Detailed Description

The following provides a more detailed description of the present invention with reference to specific embodiments,

fig. 2 shows a schematic structural diagram of the cold pad-batch dyeing machine of the present invention, which is mainly composed of a cloth feeding cooling portion 1, a cold water roller transmission portion 2, a leveling roller portion 3, and a winding portion 4, and is arranged in sequence along the upstream and downstream directions. In addition, a tensioning part 5, a limit switch 6 adapted to the tensioning part 5, and a controller (not shown in the figure) are additionally provided. The tensioning part 5 is arranged between the cold water roller transmission part 2 and the uniform padder part 3 and is used for adjusting the tension of the cloth in real time.

Fig. 3 shows a schematic structural diagram of a first embodiment of a tensioning part in a cold pad-batch dyeing machine according to the present invention, which is mainly composed of a base plate 51, a tensioning frame 52, a bearing mounting part 53, a first tensioning roller 54, a second tensioning roller 55, a torque motor 56, and the like. The tension bracket 52 is composed of a mounting panel 521 and a mounting shaft 522 extending rearward along the mounting panel 521. The first tension roller 54 and the second tension roller 55 are fixed to both ends of the mounting panel 521, and are arranged in parallel with each other at a distance. The mounting shaft 522 is rotatably inserted into and mounted on the base plate 51 via the bearing mounting portion 53, and is driven by the torque motor 56 to perform a rotational movement. The controller is connected to both the limit switch 6 and the torque motor 56. The limit switch 6 is arranged at the downstream side of the tensioning part 5 by 50-80cm, monitors the sagging amount of the cloth in real time, feeds back data to the controller in time, and sends an action signal to the torque motor 56 when the data exceeds a preset standard value in the controller. Through adopting above-mentioned technical scheme to set up, adopt torque motor 56 to carry out corresponding circumference rotary motion with real-time drive tensioning frame 52 according to the actual sag of cloth, change its length that holds to the cloth to change the tensile force of cloth, and combine limit switch 6 and controller to realize the online real-time supervision to the tensile force of cloth, and then realize the control of high accuracy permanent tension, ensure the dyeing quality of cloth.

As is known, a voice coil motor is a direct drive motor, which has the characteristics of simple structure, small size, high speed, high acceleration response, and the like. In view of the above, the torque motor 56 may preferably be a voice coil motor.

Since the first and

second tension rollers

54 and 55 are inevitably inclined with respect to the installation panel 521 after a long time of operation, the side edge of the cloth is easily warped or even folded due to the unbalanced tensile force at the moment of the rotational movement of the tension frame 52, and thus, as a further optimization of the cold pad-batch dyeing machine, the tension part 5 further includes a leveling roller 57 which is also fixed to the installation panel 521. Around the periphery of both the levelling roll 57 and the first tensioning roll 54 a cloth elastic abutment sleeve 58 is arranged. The smoothing roller 57 and the first tensioning roller 54 are arranged parallel to each other and together elastically abut against the cloth (as shown in fig. 4). In this way, in the actual operation process of the cold pad-batch dyeing machine, the cloth is always in a compressed and flat state, so that the phenomenon is avoided, and the dyeing quality is ensured.

Of course, as another modification of the above solution, the leveling roller 57 can also be used in combination with the second tensioning roller 55. Similarly, a cloth elastic abutment sleeve 58 is provided around the periphery of both the smoothing roll 57 and the second tensioning roll 55. The smoothing roll 57 is arranged in parallel with the second tensioning roll 55 and together elastically abuts against the cloth (not shown in the figure).

Fig. 5 shows a side view of a second embodiment of the tensioning part in a cold pad-batch dyeing machine according to the invention, which differs from the first embodiment described above in the following two points: 1) the leveling roller 57 is preferably detachably connected to the mounting panel 521 by means of a fastener, and accordingly, a long waist-shaped hole 5211 adapted to the fastener is formed on the mounting panel 521 to adjust the amount of the abutting force applied to the cloth. In the actual running process of the cold pad-batch coloring agent, when the abutting force applied to the cloth is inappropriate, the fastener is rotated by means of the wrench, then the relative position of the leveling roller 57 is adjusted along the long-strip waist-shaped hole 5211 according to the actual situation, and after the adjustment is completed, the fastener is locked by means of the wrench again, so that the relative distance between the leveling roller 57 and the first tensioning roller 54 or the second tensioning roller 55 can be adjusted. 2) Annular abutting flanges 581 are arranged at two ends of the cloth elastic abutting sleeve 58. Of course, similarly, with reference to the above, the annular abutting flanges 581 may be provided at both ends of the first tension roller 54 and the second tension roller 55 (as shown in fig. 6). Therefore, the cloth can be effectively prevented from deviating in the feeding process due to the offset phenomenon of the first tensioning roller 54, the second tensioning roller 55 and the leveling roller 57.

The cloth elastic abutting 58 is preferably a rubber sleeve in view of both reliability of the overall use effect and manufacturing cost.

Finally, in order to improve the friction force of the elastic cloth abutting sleeve 58 to the cloth and improve the feeding stability of the cloth, a spiral groove 582 may be further formed on the outer side wall thereof. The number of the spiral grooves 582 may be provided in plural, which are alternately arranged in the axial direction of the elastic abutting sleeve 58 (as shown in fig. 7).

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
