[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a uniformly discharging feeding device for silicone production, comprising a supporting base 1, a crushing shell 2, a feeding pipe 3, a discharge outlet 4, a drive motor 5, a first sprocket 6, a transmission gear 7, a linkage gear 8, a grinding block 9, a fixed grinding block 10, a filter screen frame 11, a second sprocket 12, a first gear 13, a second gear 14, and a guide spiral shaft 15. The supporting base 1 has the crushing shell 2 fixedly connected to its upper surface, the feeding pipe 3 fixedly attached to the upper surface of the crushing shell 2, and the discharge outlet 4 provided on the lower surface of the supporting base 1. The frame 1 is connected to the crushing shell 2. The discharge outlets 4 are evenly arranged on the lower surface of the supporting base frame 1. The first sprocket 6 is rotatably connected to the crushing shell 2. The transmission gear 7 penetrates the side surface of the crushing shell 2. The transmission gear 7 and the linkage gear 8 form a meshing connection. When using this device, the raw material is first introduced into the crushing shell 2 through the feed pipe 3, so that the raw material enters the opening at the upper end of the grinding block 9. Then, the drive motor 5 drives the first sprocket 6 and the transmission gear 7 to rotate. The transmission gear 7 drives the linkage gear 8 to rotate through the tooth block, and the linkage gear 8 drives the grinding block 9 to rotate.

[0031] A drive motor 5 is fixedly connected to the side surface of the crushing shell 2. A first sprocket 6 is fixedly connected to the output end of the drive motor 5. A transmission gear 7 is fixedly connected to the upper end of the shaft of the first sprocket 6. The linkage gear 8 is a ring design. The grinding block 9 is connected to the feed pipe 3 and the linkage gear 8 respectively. The side wall of the grinding block 9 is inclined. The filter screen frame 11 is a ring design. The fixed grinding block 10 is a conical design. The upper end of the fixed grinding block 10 penetrates the lower surface of the grinding block 9. The cavity between the grinding block 9 and the fixed grinding block 10 will grind and crush the raw material. Then the raw material falls on the surface of the filter screen frame 11 for screening, which improves the quality of the raw material. Finally, the screened raw material falls into the cavity of the support base frame 1. Through the rotation of the first sprocket 6, the first sprocket 6 drives the second sprocket 12 to rotate synchronously through the transmission chain.

[0032] A linkage gear 8 is rotatably connected to the inner wall of the cavity of the crushing shell 2. A grinding block 9 is fixedly connected to the upper surface of the linkage gear 8. A filter screen frame 11 is fixedly connected to the inner wall of the cavity of the crushing shell 2. A fixed grinding block 10 is installed on the surface of the filter screen frame 11. The linkage material distribution mechanism includes a second sprocket 12, which is rotatably connected to the side surface of the support base 1. A first gear 13 is fixedly connected to the lower end of the shaft of the second sprocket 12. A second gear 14 is rotatably connected to the side surface of the support base 1. A guide spiral shaft 15 is rotatably connected to the inner wall of the cavity of the support base 1. The rotation of the second sprocket 12 will drive the first gear 13 at the lower end to rotate. The first gear 13 will drive the second gear 14 to rotate through the tooth block. The second gear 14 will drive the guide spiral shaft 15 to rotate, so that the guide spiral shaft 15 can push the raw material to disperse through the blades on its surface.

[0033] A linkage material distribution mechanism is installed on the surface of the support base 1. The mechanism drives the first gear 13 and the second gear 14 to rotate via the second sprocket 12, which in turn drives the guide screw shaft 15 to move the raw material. A transmission chain is provided between the outer surfaces of the second sprocket 12 and the first sprocket 6. The first gear 13 and the second gear 14 are meshed together. The shaft of the second gear 14 passes through the side surface of the support base 1 and is fixedly connected to the shaft of the guide screw shaft 15. The blades on the outer surfaces of the two ends of the guide screw shaft 15 are in opposite directions. The opposite direction of the blades on the outer surfaces of the two ends of the guide screw shaft 15 facilitates the dispersion and pushing of the falling raw material. The raw material can be discharged through several discharge outlets 4, thereby improving the uniformity of material feeding and preventing the raw material from falling at fixed points and affecting production.

[0034] Working principle: When using this uniformly distributed silicone production feeding device, the raw material enters the crushing shell 2 through the feed pipe 3. Then, the drive motor 5 drives the first sprocket 6 and the transmission gear 7 to rotate, which in turn drives the linkage gear 8 and the grinding block 9 to rotate. This facilitates the grinding block 9 and the fixed grinding block 10 to crush the raw material. The raw material is filtered through the filter screen 11 and then enters the support base 1. The first sprocket 6 drives the second sprocket 12 and the first gear 13 to rotate through the transmission chain. This causes the first gear 13 to drive the second gear 14 and the guide screw shaft 15 to rotate, which facilitates the blades on the surface of the guide screw shaft 15 to push the raw material and allow it to fall into different discharge outlets 4 for discharge. This improves the uniformity of feeding and increases the overall practicality of the device.
