Background
Silicone rubber refers to rubber having a backbone composed of alternating silicon and oxygen atoms, with the silicon atoms typically having two organic groups attached to them. Silicone rubbers are further classified into heat vulcanization (high temperature vulcanized silicone HTV) and Room Temperature Vulcanization (RTV) in use. The high-temperature vulcanized silicone rubber is mainly used for manufacturing various rubber products, and the room-temperature silicone rubber is mainly used as a binder.
Common room temperature silicone rubber is silicone structural adhesive which is specially designed for structural bonding assembly in building curtain walls, has good bonding property and stability, and is widely used in the building field. At present, the common production method is to put 107 glue and calcium carbonate powder into a first mixing drum to be mixed to form a base material, then transfer the base material into a grinding device, grind the base material by a grinding rod, and then put trimethyl, titanium hydrate, coupling agent, white oil and the base material into a second mixing drum to be mixed to obtain the finished product. The above-mentioned plant also has some drawbacks in production: in the grinding device, because the base material poured into the grinding device is more, the grinding rod can not fully grind and grind the base material, so that the base material put into the second mixing drum is doped with the base material which is not ground, and a finished product mixed by the second mixing drum contains particles, so that the base material forms a solid bonding object in the bonding process, the bonding performance of the solid bonding object is poor when the grinding device is used, the base material bonded into the solid bonding object can be wasted, and if the base material is not fully ground, the bonding effect of the finished product is poor, and the utilization rate of the base material is low.

The specific implementation process is as follows:
the base material that will mix pours into the elementary grinding chamber in the operation section of thick bamboo 3, starter motor 1 and air-blower 6, let air-blower 6 last the air feed to the material pipe, increase the pressure in the material pipe, it rotates to drive gear reduction mechanism 2 and planet carrier 406 by motor 1's output shaft 101, utilize planetary gear train to accelerate the rotation of filter sieve portion, realize that the planet carrier is the input shaft, the shaft of sun gear is the output shaft, drive first filter 301 through sun gear 405, second filter 302 and riser rotate, thereby because the rotation of filter sieve portion drives big grinding ball and the little grinding ball rotation in elementary grinding chamber and the second grade grinding chamber, thereby grind the base material, and in first filter 301 and second filter 302 pivoted, can filter the base material of grinding, specifically do: when the base material in the primary grinding chamber is ground by the large grinding balls and the diameter of the base material is smaller than that of the first filtering holes, the base material can enter the secondary grinding chamber through the first filtering holes; after the base material in the secondary grinding chamber is ground by the small grinding balls, the diameter of the base material is smaller than that of the second filtering holes, the base material can enter the finished product chamber through the second filtering holes, and the first filtering plate, the second filtering plate and the vertical plate are driven by the sun gear to rotate clockwise, so that the base material in the primary grinding chamber is ground by the first filtering plate, the base material with the diameter smaller than that of the first filtering hole is pressed into the secondary grinding chamber, and the base material can not return to the primary grinding chamber again after entering the secondary grinding chamber because the first filtering plate, the second filtering plate and the vertical plate rotate clockwise. The base stock is screened in the primary grinding chamber and the secondary grinding chamber to obtain fully ground base stock.
By setting the time required for triggering the time controller 904, at this time, each stage of grinding chamber just restores to the original position, and the time controller 904 is triggered, so that the electromagnet 903 is powered off and demagnetized, at this time, the motor is turned off, and the motor stops working, the spring 901 overcomes the repulsive force between the sliding plate 902 and the electromagnet 903 to drive the sliding plate 902 to slide towards the inner side of the groove, because the fan-shaped notch is positioned under the second stage grinding chamber and the cross-sectional area of the fan-shaped notch is consistent with that of the second stage grinding chamber, the fan-shaped notch is not sealed, the base material accumulated in the second stage grinding chamber and can not pass through the second filtering hole falls into the collecting chamber 7, the recovered base material in the collecting chamber 7 is adsorbed by the negative pressure generated by the throat of the venturi tube, so that the base material tube is transferred into the base material tube 801, and the base material which is not fully ground is blown, the communicating part of the material pipe 801 is just positioned in the primary grinding chamber, and because the motor is stopped at the moment, the energy is stored by the torsion spring when the motor rotates, the torsion spring releases energy after the motor is stopped, and the rotating shaft is driven to rotate reversely under the action of the torsion spring, so that the baffle plate 8 is opened. Since there is a pressure difference between the inside and the outside of the material pipe 801 by the blower 6, when the material pipe 801 is not sealed by the baffle plate 8, the base material in the material pipe 801 is ejected from the horizontal section of the material pipe 801 toward the primary grinding chamber by the pressure difference.
After discharging for 1min, the time controller 904 is powered on again, so that the electromagnet 903 is powered on to generate repulsion to the sliding plate 902, the pulling force of the spring 901 is overcome, the sliding plate 902 is pushed to slide towards the fan-shaped notch, and finally the fan-shaped notch is sealed. The base material after being fully ground finally enters the finished product chamber, and the base material in the finished product chamber is collected after the grinding process is finished.
