[0002] Silicone rubber is a rubber with a backbone composed of alternating silicon and oxygen atoms, typically with two organic groups attached to the silicon atoms. Ordinary silicone rubber is primarily composed of silicon-oxygen chain segments containing methyl groups and a small amount of vinyl groups. Currently, during silicone rubber processing, silicone rubber mixers typically place rubber pellets directly into the mixer. This results in varying sizes of rubber pellets and inconsistent melting rates, impacting the melting process.

[0004] However, the above device has the following technical problems when actually used:

[0005] 1. In the above device, the silica gel material passes through the gap between the conveyor belt and the screen plate, and the gap is used to screen out the larger material. However, the screened material is manually taken out of the conveyor belt. On the one hand, it is necessary to manually observe the screening situation in real time, thereby increasing the labor intensity. On the other hand, the above device lacks a secondary processing and utilization device for the screened material, which will cause material waste and cost loss.

[0006] 2. In addition, in the above device, a heating device is provided at the bottom of the mixing box. When all the materials are piled up inside the mixing box, the heat transfer will be affected, so that the materials on the upper layer cannot be heated and melted quickly, affecting the mixing efficiency of the silicone material. Utility Model Content

[0007] The utility model provides a rubber mixing machine for silica gel production, aiming to solve the problem mentioned in the above-mentioned background technology that unqualified products in the above-mentioned device are directly taken out manually, which on the one hand increases the labor cost required for manual labor, and on the other hand, the unqualified products cannot be reused, which easily causes cost loss. In addition, the heating device in the above-mentioned device is arranged at the bottom of the mixing box, and its heat cannot be quickly transferred to the upper material, thereby affecting the melting efficiency of the upper material.

[0008] The utility model is realized as follows: a mixing and refining machine for silica gel production comprises: a mixing box body, a stirring tank is provided on the top wall of the mixing box body, a column is fixedly installed upright in the mixing tank, an annular stirring chamber is provided on the outer side of the column, a stirring mechanism comprises: a rotating plate rotatably connected to the column, both ends of which are movably connected to a stirring assembly, the stirring assembly extends into the stirring chamber, a feeding box body is arranged above the mixing box body, and a feeding trough is provided corresponding to the stirring chamber, and a discharge trough located on one side of the feeding trough is further provided in the feeding box body, the discharge trough is connected to the feeding trough, a feeding port connected to the discharge trough is provided on the top wall of the feeding box body, a feeding mechanism comprises: a sieve plate correspondingly arranged above the feeding port, a conveying device is provided on one side of the sieve plate, and a crushing assembly is provided on the other side, and the crushing assembly is arranged in the feeding trough; in this scheme, the device is composed of a conveying device. The device transports the silica gel material to the screen plate, and the material rolls toward the crushing box along the inclined screen plate. The qualified material will pass through the sieve holes on the screen plate and fall into the discharge chute along the feed port, then enter the feeding chute along the discharge chute and finally enter the mixing tank to wait for subsequent mixing processing, while the unqualified material cannot pass through the sieve holes and will eventually roll into the crushing box. The first crushing roller and the second crushing roller crush the unqualified material to reduce its volume to meet the processing requirements, and then the qualified material after crushing enters the mixing tank along the feeding chute. The qualified material in this device will directly pass through the sieve holes and fall into the discharge chute along the feed port, and finally be discharged along the feeding chute, while the unqualified material will enter the crushing box, be crushed by the crushing components and then discharged along the feeding chute, reducing the workload of manual pickup of unqualified products. At the same time, the unqualified products can also be processed and reused for secondary processing, reducing cost losses.

[0009] In addition, in this device, heating elements are provided on the inner and outer circumferential walls of the annular stirring chamber. When the heating elements are working, the heat generated by them, combined with the rotating stirring components, can transfer the heat evenly and quickly to the materials at various locations, thereby heating and melting the materials and improving the mixing efficiency of the silicone material.

The driving gear on the rotating shaft and the gear ring on the outer wall of the column are engaged with each other, and the driving gear is fixedly installed on the rotating shaft. Therefore, under the influence of the engagement of the driving gear and the gear ring, the rotating shaft itself rotates, thereby controlling multiple stirring rods to rotate around the rotating shaft, thereby realizing stirring processing of the material in the stirring chamber.

[0011] Preferably, a heating device is further included, which comprises: a first heating element arranged around the inner peripheral wall of the stirring tank, and a second heating element fixed around the outer wall of the column and corresponding to the first heating element; in this scheme, by respectively arranging the first heating element and the second heating element on the inner peripheral wall and the outer peripheral wall of the annular stirring chamber, rapid heat conduction can be achieved, and the material is stirred by the rotating stirring component so that it is evenly contacted with the heating element, and the heat generated by the heating element is used to melt the material.

At this time, the output end of the second motor drives the first crushing roller to rotate, and the first crushing roller drives the second crushing roller on the other side to rotate in the opposite direction through the transmission of two mutually meshing control gears. The first crushing roller and the second crushing roller crush the material between the two, so that the volume of the material is reduced to a specified size. After crushing, the qualified size material is discharged into the stirring chamber along the feeding trough and waits for subsequent melting processing.

[0013] Preferably, the screen plate is tilted, with its end close to the conveying device higher than its end close to the crushing box, and a number of sieve holes are provided on the screen plate at equal intervals; in this scheme, the purpose of tilting the screen plate is to facilitate the free rolling of the material output by the conveying device, and to use the sieve holes to screen the qualified products without manual intervention, thereby greatly improving the automatic screening function of the device and reducing the workload required by manual labor.

[0014] Preferably, the inner bottom wall of the discharge trough is formed with a guide slope, and the height of the end close to the feeding trough is lower than the height of the end away from the feeding trough; in this scheme, the purpose of the inclined setting of the inner bottom wall of the discharge trough is to facilitate the rapid fall of qualified materials after screening into the feeding trough, avoid accumulation in the discharge trough, and prevent material accumulation from affecting the subsequent material transportation.
