The open type rubber mixing machine has two horizontally arranged rollers, and the mechanical rubber mixing between the two rollers is called an open mill. It is mainly composed of rollers, racks, distance adjusting devices and transmission devices. The material is pulled into the gap between the rollers at different linear speeds under the action of friction between the two opposite rotating rollers.

[0042] When it is needed to open the valve piece 209, just start the No. 2 motor 303, the No. 2 motor 303 drives the connecting rod 304 to move downwards through the reciprocating screw rod 302, the connecting rod 304 drives the No. 2 sliding seat 305 to move downwards, thereby drives the cutting rod 307 to move downwards, the cutting rod 307 drives the cutting knife 309 to cut the raw material pushed out of the pushing material port 208, the No. 2 sliding seat 305 moves downwards at the same time drives the No. 1 moving plate 312 to move downwards through the No. 1 supporting rod 311, because of the setting of the shape of the rotating groove 315, when the No. 1 moving plate 312 drives the tooth block 316 to mesh with the No. 1 gear 310 to move downwards, the tooth block 316 cannot rotate, thereby drives the No. 1 gear 310 to rotate 90 degrees, it is needed to be explained that the gear racks on the No. 1 moving plate 312 and the No. 2 moving plate 314 can only drive the No. 1 gear 310 to rotate half a circle, thereby makes the valve piece 209 open, at this time the pushing material port 208 pushes the material, when the cutting knife 309 moves to the discharging port, the tooth block 316 on the No. 2 moving plate 314 meshes with the No. 1 gear 310, thereby drives the valve piece 209 to close, stops discharging, it is needed to be explained that because of the setting of the shape of the rotating groove 315, when the No. 1 moving plate 312 and the No. 2 moving plate 314 move upwards, the tooth block 316 will be driven to rotate by the No. 1 gear 310, thereby cannot drive the No. 1 gear 310 to rotate, and the tooth block 316 will be driven to reset by the torsion spring after moving through the No. 1 gear 310, when it is needed to adjust how much raw material the pushing material port 208 pushes out, it is needed to be explained that Figure 1 The most pushing material amount is shown in the middle, just start the No. 3 motor 308, the No. 3 motor 308 drives the cutting rod 307 to move downwards through the No. 1 threaded rod 306, thereby shortens the distance between the cutting knife 309 and the pushing material port 208, thereby reduces how much raw material the pushing material port 208 pushes out

[0043] Please pay attention to Figures 1-4The end of the cutting rod 307 is provided with a reset mechanism 400. The cutting rod 307 is provided with a connecting rod 401 at both ends.

The bottom end of the inner wall of the sliding rod 102 is rotatably connected with a plurality of rollers 103. The bottom end of the plurality of rollers 103 is attached to the bottom end of the T-shaped sliding groove 101.

[0044] When the cutting knife 309 cuts off the raw material, the connecting rod 401 just drives the first gear rack 402 to mesh with the second gear 403, thereby driving the second gear 403 to rotate. The second gear 403 drives the second transmission disc 404 to rotate. The second transmission disc 404 drives the third transmission disc 406 to rotate through the second transmission belt 407. The third transmission disc 406 drives the third gear 408 to rotate through the rotating rod 405. The third gear 408 can drive the toothed column 409 to rotate in the opposite direction. The toothed column 409 can drive the sliding rod 102 to move away from the rubber mixing machine through the second gear rack 410, thereby facilitating manual operation of the rubber mixing machine. When it is necessary to push the material again, the second motor 303 is started again. The second motor 303 drives the first gear rack 402 to move upward through the reciprocating lead screw 302, thereby driving the toothed column 409 to reverse rotation, which can drive the sliding rod 102 to reset.

[0045] Please refer to Figures 1-9 The top end of the base 100 is provided with a discharging mechanism 500. The discharging mechanism 500 comprises an adjusting seat 501.

The output end of the fourth motor 503 penetrates through the outer wall of the adjusting seat 501 and is fixedly connected with the end of the second threaded rod 502.

[0046] When the sliding rod 102 moves away from the rubber mixing machine, the jacking rod 507 can push the cover plate 212 open through the push rod 213, at which time the conveying belt 506 can be started to drop the raw materials through the feeding hopper into the premixing barrel 201, and the fourth motor 503 can be started to drive the sliding block to move forward and backward through the second threaded rod 502, thereby driving the mounting plate 505 to move, which in turn drives the conveying belt 506 to adjust the position forward and backward, so that when the cutting knife 309 is adjusted in the up-down position, the moving distance of the pushing port 208 and the cutting knife 309 will also change accordingly, and the position of the conveying belt 506 can be adjusted to adapt to the position of the feeding hopper.

[0047] In use, the two groups of screw rods 202 in the premixing pushing mechanism 200 can preliminarily premix the raw materials in the premixing barrel 201, reducing the mixing time of the raw materials on the rubber mixing machine and improving the work efficiency. The raw materials are premixed while moving to the pushing port 208, and the premixed raw materials are pushed to the rubber mixing machine through the pushing port 208, realizing automatic pushing and avoiding manual feeding, preventing the fingers from being accidentally rolled into the gap between the two groups of rollers when feeding manually, and improving the safety. The setting of the first moving plate 312 and the second moving plate 314 in the cutting mechanism 300 can adjust the height of the cutting knife 309 through the third motor 308, thereby adjusting the time when the cutting knife 309 moves to the pushing port 208, realizing the control of the pushing of the raw materials by the pushing port 208, and adjusting how much raw materials are pushed out of the pushing port 208 according to the specific use. After the cutting knife 309 cuts off the raw materials, the sliding rod 102 can move away from the rubber mixing machine, thereby driving the pushing port 208 and the cutting knife 309 to move away from the rubber mixing machine, preventing the rubber in the rubber mixing machine from being touched by the cutting knife 309 or the pushing port 208 when the rubber is being prepared, and facilitating manual operation of the rubber mixing machine. When the pushing port 208 and the cutting knife 309 move away from the rubber mixing machine, the jacking rod 507 can push the cover plate 212 open through the push rod 213, at which time the conveying belt 506 can be started to drop the raw materials through the feeding hopper into the premixing barrel 201, and the fourth motor 503 can control the forward and backward position of the conveying belt 506, so that when the cutting knife 309 is adjusted in the up-down position, the moving distance of the pushing port 208 and the cutting knife 309 will also change accordingly, and the position of the conveying belt 506 can be adjusted to adapt to the position of the feeding hopper.
