[0002] Silicone products refer to products made from silicone as the main raw material. Silicone products can be divided into three categories according to their molding process: molded silicone, extruded silicone and liquid silicone. Molded silicone products are usually made by placing solid silicone raw materials with added vulcanizers in high-temperature molds and applying pressure through a vulcanizing machine to solidify them at high temperature. In the processing of silicone products, in order to improve the quality of silicone products, the silicone raw materials need to be ground.

[0003] The existing traditional method is to directly use a grinding disc for grinding. Due to the different sizes of silica gel, larger sizes are not convenient for grinding, which affects the processing efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide a grinder for silica gel production, which solves the problem that silica gel of different sizes is not convenient to grind due to the use of grinding discs and affects the processing efficiency by setting a crushing mechanism.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A grinding machine for silica gel production, comprising a box body, a feed port fixedly connected to the top of the box body, a discharge port opened at the bottom of the box body, and a grinding mechanism connected to the box body, and also comprising a screening box plugged into the inside of the box body, a crushing mechanism connected to the side wall of the box body, and a screening mechanism connected to the screening box;

[0007] The crushing mechanism comprises a first driving member connected to the side wall of the box body, and a first crushing roller and a second crushing roller movably arranged inside the box body for crushing the silica gel;

[0008] The screening mechanism comprises a stirring motor fixedly connected to the outer side wall of the screening box, and a stirring rod movably arranged inside the screening box for stirring the silica gel.

[0009] Preferably, the first driving member includes a driving motor fixedly connected to the outer wall of the box body, a transmission shaft fixedly connected to the output end of the driving motor, a driven shaft passing through the side wall of the box body and rotatably connected to the side wall of the box body, a main gear fixedly connected to the outer wall of the transmission shaft, and a transmission gear fixedly connected to the outer wall of the driven shaft.

[0010] Preferably, the first crushing roller is fixedly connected to the outer side wall of the driven shaft, and the second crushing roller is fixedly connected to the outer side wall of the transmission shaft.

[0011] Preferably, the screening box comprises a mounting plate, a bearing frame fixedly connected to the top of the mounting plate, guide holes provided on the outer side wall of the bearing frame, and a screening net fixedly connected to the bottom of the bearing frame.

[0012] Preferably, the screening mechanism comprises a positioning block fixedly connected to the output end of the stirring motor, a stirring shaft sleeved on the outer side wall of the positioning block, and a fixing bolt penetrating the stirring shaft and threadedly connected to the positioning block;

[0013] The stirring rod is fixedly connected to the outer side wall of the stirring shaft.

[0014] Preferably, the screening mechanism further comprises a sliding rod fixedly connected to the inner wall of the box body, a knob rotatably arranged on the outer wall of the box body, and a limit block fixedly connected to the outer wall of the knob.

[0015] Preferably, the grinding mechanism comprises a second driving member fixedly connected to the outer side wall of the box body, and a first grinding roller and a second grinding roller movably arranged inside the box body;

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. In the utility model, silica gel is added into the box body through the feed port, and the drive motor is started, so that the drive motor drives the transmission shaft to rotate forward, and the cooperation of the main gear and the transmission gear drives the driven shaft to rotate reversely, thereby driving the two crushing rollers to rotate in opposite directions, thereby crushing the silica gel, avoiding the inability to grind large-sized silica gel.

[0019] 2. In the utility model, by placing the collection box below the discharge port, the crushed silica gel will fall into the interior of the screening box under the action of gravity. At this time, the stirring motor is in working state, thereby driving the stirring shaft and the stirring rod to rotate, so that the small-sized silica gel passes through the screening net and falls between the two grinding rollers, while the large-sized silica gel remains in the interior of the screening box, and the small-sized silica gel is polished by the grinding roller and finally transported to the collection box through the discharge port. Then, by turning the knob, the knob drives the limit block away from the screening box, and then the screening box is pulled out and the fixing bolts are removed. At this time, the stirring rod can be taken out from the interior of the screening box, so that the large-sized silica gel inside the screening box can be cleaned conveniently.
