[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] 1. The feeding device for rubber processing is provided with a uniform feeding component group. The discharge port design of the existing spiral elevator cannot ensure uniform blanking of materials. Especially when dealing with viscous or irregular granular materials, it is easy to cause material accumulation, affecting the feeding effect of the spiral elevator on rubber particles. In the corresponding designed uniform feeding component group, the spiral elevator pipe body lifts the rubber particle materials, and then discharges them from the discharge port position of the spiral elevator pipe body. The discharged rubber particles will fall into the material distribution hopper frame. As the servo motor at the bottom of the material distribution hopper frame starts, the servo motor will drive the large gear member and the small gear member through the working end. The rotation of the small gear member drives the large gear member and the reciprocating lead screw, and then can drive the side connecting arm and the movable blanking nozzle to move. The movable blanking nozzle and the guiding plate will slide at the bottom position of the material distribution hopper frame through the sliding grooves. As the reciprocating lead screw continues to rotate, the reciprocating lead screw will make the side connecting arm and the movable blanking nozzle reciprocate, thereby enabling the rubber particles in the material distribution hopper frame to be uniformly blanked, avoiding material accumulation, and improving the feeding effect of the spiral elevator on rubber particles;
[0015] 2. The feeding device for rubber processing is provided with a dust-proof component group. A uniform feeding structure is required to prevent dust so as to avoid dust entering the material, resulting in contamination of the rubber particles and ensuring the quality and performance of the finished product. In the corresponding designed dust-proof component group, the upper sleeve housing covers the discharge port of the screw elevator pipe body and the top of the material distribution hopper frame, preventing dust from entering the material distribution hopper frame from the top and mixing into the material. The length of the lower guiding pipe can be cut according to the distance between the movable blanking nozzle and the bottom receiving mechanism in actual use, so that the material distribution hopper frame can just be located 5 cm above the receiving mechanism, while still ensuring that the connecting plate II and the material distribution hopper frame can move with the movable blanking nozzle. This design can further prevent dust from mixing into the material. The weight frame member in the dust-proof component group is used to increase the weight at one end of the lower guiding pipe, ensuring that the relatively light lower guiding pipe can move with the movable blanking nozzle. The overall design of this dust-proof component group can improve the sealing performance of the screw elevator during material transportation, preventing dust or impurities in the external environment from mixing into the rubber particles, thereby improving the quality and performance of the finished product.

A side connecting arm 213 is arranged outside the reciprocating lead screw 212; a dust-proof component group 03 is arranged outside the even feeding component group 02.

There are two second connecting plates 22, and the two second connecting plates 22 are connected to both sides of the two first connecting plates 21. The second connecting plate 22 is connected with the material distribution hopper frame 23.
[0026] The material distribution hopper frame 23 is provided with sliding grooves corresponding to the positions of the movable blanking nozzle 24 and the guiding plate 25, and the material distribution hopper frame 23 is in sliding contact with the movable blanking nozzle 24 and the guiding plate 25 through the sliding grooves. A retaining plate is connected to the side of the guiding plate 25 away from the movable blanking nozzle 24.
[0027] Openings are arranged at the top and bottom of the movable blanking nozzle 24. Openings are arranged at the top and bottom of the material distribution hopper frame 23. The servo motor 28 is installed on the first lower frame 26 through a mounting bracket. The working end of the servo motor 28 is connected with the large gear member 29. The large gear member 29 meshes with the small gear member 210. There are two end rod shafts 211, and the two end rod shafts 211 are connected to both ends of the reciprocating lead screw 212. One end rod shaft 211 is connected to the first lower frame 26 through a bearing, and the other end rod shaft 211 is connected to the second lower frame 27 through a bearing. The side connecting arm 213 is connected with the reciprocating lead screw 212 through a nut pair. The side connecting arm 213 is connected with the movable blanking nozzle 24.
[0028] The dust-proof component group 03 includes an upper sleeve housing 31, and a lower guide pipe 32 and a counterweight frame member 33 are arranged at the bottom of the upper sleeve housing 31.
[0029] The upper sleeve housing 31 is connected to the top of the material distribution hopper frame 23. The upper sleeve housing 31 is provided with a hole corresponding to the discharge port position of the screw elevator pipe body 01, and the upper sleeve housing 31 is in contact with the screw elevator pipe body 01 through the hole, and a sealing strip is installed at the contact position between the hole of the upper sleeve housing 31 and the screw elevator pipe body 01.

[0031] Working principle: The discharge port design of the existing screw elevator cannot ensure the uniform discharging of materials. Especially when dealing with sticky or irregular granular materials, it is easy to cause material accumulation, affecting the feeding effect of the screw elevator for rubber particles. In the corresponding designed uniform feeding component group 02, the screw elevator tube body 01 lifts the rubber particle material, and then discharges it from the discharge port position of the screw elevator tube body 01. The discharged rubber particles will fall into the material distribution hopper frame 23. As the servo motor 28 at the bottom of the material distribution hopper frame 23 starts, the servo motor 28 drives the large gear part 29 and the small gear part 210 through the working end. The rotation of the small gear part 210 drives the large gear part 29 and the reciprocating lead screw 212, and then can drive the side connecting arm 213 and the movable discharging nozzle 24 to move. The movable discharging nozzle 24 and the guiding plate 25 will slide at the bottom position of the material distribution hopper frame 23 through the chute. As the reciprocating lead screw 212 continues to rotate, the reciprocating lead screw 212 will make the side connecting arm 213 and the movable discharging nozzle 24 move reciprocally, so as to uniformly discharge the rubber particles in the material distribution hopper frame 23, avoid material accumulation, and thus improve the feeding effect of the screw elevator for rubber particles. The uniform discharging structure is required to prevent dust to avoid dust entering the material and contaminating the rubber particles, ensuring the quality and performance of the finished product. In the corresponding designed dust-proof component group 03, the upper sleeve housing 31 covers the discharge port of the screw elevator tube body 01 and the top of the material distribution hopper frame 23 to prevent dust from entering the material distribution hopper frame 23 from the top and mixing into the material. The length of the lower guiding tube 32 can be cut according to the distance between the movable discharging nozzle 24 and the bottom receiving mechanism in actual use, so that the material distribution hopper frame 23 can just be located 5 centimeters above the receiving mechanism, and at the same time, it can still ensure that the connecting plate two 22 and the material distribution hopper frame 23 can move with the movable discharging nozzle 24. This design can further prevent dust from mixing into the material. The counterweight frame part 33 in the dust-proof component group 03 is used to increase the counterweight at one end of the lower guiding tube 32 to ensure that the relatively light lower guiding tube 32 can move with the movable discharging nozzle 24. The overall design of this dust-proof component group 03 can improve the sealing performance of the screw elevator during material transportation, prevent dust or impurities in the external environment from mixing into the rubber particles, and thus improve the quality and performance of the finished product.
