Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a high viscous fluid crosslinking device and a sealant-

Embodiments of the present invention relate to a high viscosity fluid crosslinking apparatus and a sealant coated tire manufacturing apparatus comprising the same.

The vehicles that the users are traveling with are made up of many parts, among which the tires have a great effect on the driving of the vehicle, and can be said to be one of the key components for securing the safety of the user.

If the tire is damaged by a sharp object such as a nail, it must be replaced or repaired. However, research and development on sealant tires and run-flat tires, which can travel a certain distance even if a puncture has recently occurred in a tire, is continuing.

Sealant tires are tubeless tires that have improved performance to withstand punctures. They are made by attaching a special rubber layer to a thin rubber layer called an inner liner, which is attached to the inner wall of the tread of a tire.

The role of the rubber layer is to surround the nail even if the nail penetrates the tread, and even if the nail falls off, the wound hole is naturally sealed so that no air leaks.

In order for the sealant to fill the puncture, the sealant must be a material having high viscosity and viscoelasticity. The sealant material undergoes a cross-linking reaction at a high temperature after mixing. To crosslink the sealant material, the high viscosity fluid is supplied with heat using a heating plate and a heating band, or using a heating chamber. However, a high viscosity fluid has a high viscosity and specific heat, so that there is a temperature difference between the material at the position where the heat is directly supplied and the material at the position where it is not. When a temperature difference occurs between the materials, the degree of the crosslinking reaction is also varied, and the physical properties of the material are varied when the crosslinking is finally completed.

Therefore, research is needed to reduce the quality variation by uniformly heating a high viscosity fluid having a high viscosity, a high boiling point, and a low thermal conductivity.

The connecting member 122 may transmit the rotational driving force in one direction of the rotational driving module 123 and may transmit the rotational driving force to the rotating roller 121 arranged in a direction different from the one direction by the angle adjusting unit 140. For example, the connecting member 122 may be a universal joint.

The angle adjuster 140 seats the other side of the drum 110 and raises or lowers the other side of the drum 110 so that the angle of the first axis A1 of the drum 110 ) Can be adjusted. The angle adjusting part 140 adjusts the height of the other side of the drum part 110 in a state where the height of the drum part 110 from the ground surface of the drum part 110 is fixed, The angle can be adjusted.

The angle adjusting unit 140 may include a first guide roller 141 and a first up / down drive module 143.

The supporting unit 150 includes a plurality of support units 150, The drum unit 110 may be supported. Hereinafter, for convenience of explanation, the case where only one support 150 is provided will be described.

As shown in FIG. 2, the supporting part 150 may be disposed at a position to support the drum part 110 in response to the movement of the first axis A1 by the angle adjusting part 140. The supporting portion 150 may include a second guide roller 151 and a second up-down driving module 153. The second guide roller 151 can support the drum unit 110 while guiding the movement of the drum unit 110 as the drum unit 110 rotates. At this time, the drum unit 110 may be provided with a third guide rail R3 for guiding the second guide roller 151.

The second up-down driving module 153 may be formed of a cylinder, a piston, a rotating machine, or the like, in the same manner as the first up-down driving module 143.

On the other hand, the heat generating unit 160 can transmit heat to the high viscosity fluid. The heating unit 160 may be a heating plate or a heating band connected to the drum unit 110 to transmit heat by conduction and may be a heating chamber for transferring heat by convection . The present invention is not limited to the type of the heat generating unit 160, but in FIG. 2, the case where the heat generating chamber is formed of the heat generating unit 160 is shown as an example. The heat generating unit 160 may include a temperature sensor (not shown) although not shown.

FIG. 3 is a block diagram showing the high viscosity fluid bridging apparatus 100 shown in FIG. 2, and FIG. 4 is a state diagram showing an operating state of the high viscosity fluid bridging apparatus 100 shown in FIG.

Referring to FIGS. 3 and 4, a control method of the high viscosity fluid crosslinking apparatus 100 by the control unit 130 can be described.

The high viscous fluid (M) can be completed through cross-linking reaction when heat is supplied to the mixed high-viscosity materials. When the high viscosity fluid (M) is crosslinked in a large amount, uniform heat is supplied to the entire high viscosity fluid (M) stored in the drum portion (110) to obtain uniform physical properties of the high viscosity fluid (M). Therefore, the highly viscous fluid M can obtain uniform physical properties through a constant flow.

The viscosity of the high viscosity fluid (M) varies with the crosslinking time after mixing. The high viscosity fluid (M) has a low viscosity immediately after mixing, and maintains a high viscosity after a certain crosslinking time. Therefore, the viscosity of the high-viscosity fluid (M) must be changed in accordance with the viscosity change so that a uniform crosslinking reaction can be achieved.

The control unit 130 may be connected to the rotation driving unit 120 to control the rotation speed of the drum unit 110 receiving the highly viscous fluid M. For example, the rotational speed may be selected in the range of 0.01 RPM to 1 RPM, and the crosslinking time may be selected in the range of 1 hour to 120 hours. The control unit 130 may control the rotation driving unit 120 to adjust the rotation speed of the drum unit 110 according to the state of the viscous fluid M or the crosslinking time. Specifically, the control unit 130 may control the rotation driving unit 120 so that the rotational speed of the drum unit 110 is sequentially decreased according to the crosslinking time. Since the viscosity of the high viscosity fluid increases with the crosslinking time, the controller 130 reduces the rotation speed of the drum portion 110 according to the crosslinking time based on the state of the highly viscous fluid M, So that a continuous and uniform flow can be generated in the high-viscosity fluid (M). The control unit 130 may control the rotation driving unit 120 such that the drum unit 110 is repeatedly rotated clockwise and counterclockwise. The control unit 130 may store the rotation speed of the drum unit 110 according to the crosslinking time. An example of the rotation speed table of the drum unit 110 according to the crosslinking time is shown in Table 1 below.

Bridging time (hour) Rotational Speed (RPM) 0-12 One 12 to 24 -0.9 24 to 36 0.8 36 to 48 -0.7 48 to 60 0.6 60 to 72 -0.5 72 ~ 84 0.4 84 ~ 96 -0.3 96-108 0.2 108 ~ 120 -0.1

Here, when the rotation speed has a positive value, it may be a rotation in a clockwise direction, and when the rotation speed is a negative value, it may be a rotation in a counterclockwise direction. However, the above table is only one example, and the present invention is not limited thereto. When the rotation speed has a positive value, it rotates counterclockwise, and when the rotation speed has a negative value, it may rotate clockwise. Table 1 shows the case where the rotational speed is linearly decreased according to the crosslinking time, but the table may be set to have a different width for each time period. In another embodiment, the high viscosity fluid crosslinking apparatus 100 further includes a viscosity sensor (not shown) to adjust the rotation speed of the drum portion 110 according to the viscosity of the high viscosity fluid measured through a viscosity sensor .

The control unit 130 may control the angle adjusting unit 140 such that the drum unit 110 has an inclination with respect to the paper surface. The control unit 130 controls the first up-down driving module 143 of the angle adjusting unit 140 so that the other side of the drum unit 110 is raised or lowered, thereby rotating the drum unit 110 in the vertical direction The angle [theta] of the first axis A1 can be adjusted. The control unit 130 can control the angle [theta] of the first axis A1 within a range of 0 [deg.] To 90 [deg.], For example.

At this time, the control unit 130 may control the support unit 150 in response to the movement of the angle control unit 140. Specifically, when the first up-down driving module 143 of the angle adjusting unit 140 is raised, the controller 130 may lower the second up-down driving module 153 of the supporting unit 150. [ Accordingly, the support portion 150 can support the drum portion 110 which is inclined by the angle adjusting portion 140. [

Meanwhile, the control unit 130 may control the heat generating unit 160 to crosslink the high viscosity fluid at a predetermined temperature. The control unit 130 may be connected to a temperature sensor (not shown) to sense the temperature change of the high viscosity fluid. When the temperature of the high viscous fluid becomes lower than a preset temperature set by the user, the controller 130 can drive the heat generating unit 160.

As described above, the high viscosity fluid crosslinking apparatus 100 according to an exemplary embodiment of the present invention rotates the drum portion 110 that receives the high viscosity fluid during the crosslinking of the high viscosity fluid M, thereby achieving a constant flow to the high viscosity fluid So that the high viscosity fluid can have a homogeneous physical property by a homogeneous crosslinking reaction.

The control unit 130 may also be embodied in the form of a recording medium including instructions executable by a computer such as a program module executed by a computer. Computer readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. In addition, the computer-readable medium may include both computer storage media and communication media. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Communication media typically comprise any information delivery media, including computer readable instructions, data structures, program modules, or other data, or transport mechanisms, of a modulated data signal such as a carrier wave.
