[0002] Plastic granulation is a process of plastic mechanical processing. In the process of plastic granulation, we must explore according to the performance of the machine and practice, master the skills, and continuously improve the quality and process of plastic products. The screw and barrel of the granulation extruder adopt the advanced "building block" design. The screw is composed of various forms of screw blocks mounted on the core shaft, and the inner sleeve in the barrel can be adjusted according to the different screw blocks.

[0003] After searching, a Chinese patent with publication number CN218660364U discloses a quantitative feeding mechanism for a plastic extruder, comprising a housing, a plastic extruder is arranged inside the housing, and a plurality of heating plates are arranged on one side of the housing. The utility model can quantitatively deliver plastic particles into the plastic extruder when in use by arranging a feeding mechanism.

For this reason, we provide a quantitative batching mechanism for a plastic particle extruder to solve the above problems. Utility Model Content

[0031] See also Figure 2 A screening mechanism 2 is arranged above the bottom plate 1, and the screening mechanism 2 includes a screening box 201. A hydraulic rod 202 is fixedly connected to the inner wall of the screening box 201, and a shaking plate 203 is fixedly connected to the telescopic end of the hydraulic rod 202. The outer surface of the shaking plate 203 is slidably connected to the screening box 201. The arrangement of the hydraulic rod 202 can effectively prevent the shaking plate 203 from sliding up and down too violently, and can effectively buffer a small part of the pressure, thereby increasing the service life of the shaking plate 203.

[0032] A spring 204 is sleeved on the outer surface of the hydraulic rod 202, one end of the spring 204 is fixedly connected to the screening box 201, and the end of the spring 204 away from the screening box 201 is fixedly connected to the shaking plate 203. The resilience of the spring 204 can effectively make the shaking plate 203 fixedly connected to the screening box 201 and the shaking plate 203 through the two ends of the shaking plate 203, so that it is more stable when rebounding.

[0033] The outer surface of the shaking plate 203 is fixedly connected to the filter plate 205, and the inner wall of the filter plate 205 is rotatably connected to the fixing rod 206. The two ends of the fixing rod 206 are fixedly connected to the screening box 201. Through the setting of the fixing rod 206, the filter plate 205 can effectively move up and down with the fixing rod 206 as the center.

[0034] The inner wall of the shaking plate 203 is fixedly connected to a motor 207, the outer surface of the bottom plate 1 is provided with a control button of the motor 207, the output end of the motor 207 is fixedly connected to a fan-shaped gravity block 208, by turning on the motor 207, the fan-shaped gravity block 208 can be effectively driven to rotate, and the gravity generated by the rotation of the fan-shaped gravity block 208 can drive the filter plate 205 to shake up and down.

[0035] The bottom surface of the screening box 201 is fixedly connected to the guide box 3, the bottom surface of the guide box 3 is fixedly connected to the bottom plate 1, and the top surface of the screening box 201 is fixedly connected to the feed port 4. The setting of the feed port 4 makes it more convenient to guide the raw materials to the inside of the screening box 201, and the slope setting of the guide box 3 can effectively concentrate the plastics in one place waiting for transportation.

[0036] See also Figure 3 A conveying mechanism 5 is arranged inside the bottom plate 1, and the conveying mechanism 5 includes a fixing frame 501, the bottom surface of the fixing frame 501 is fixedly connected to the bottom plate 1, a fixing block 502 is fixedly connected to the inner top wall of the fixing frame 501, a motor 2 503 is fixedly connected to the inner wall of the fixing block 502, and the motor 2 503 is arranged to have a double-head output. A control button of the motor 2 503 is installed on the outer surface of the bottom plate 1, and the setting of the fixing block 502 can effectively support and fix the motor 2 503.

[0037] The output end of motor 2 503 is fixedly connected to a gear 504, and the outer surface of the gear 504 is fixedly connected to a rotating rod 505. The end of the rotating rod 505 away from the gear 504 is rotatably connected to the base plate 1. The setting of the rotating rod 505 effectively limits the gear 504, making the gear 504 more stable when rotating.

By rotating the gear 504 and cooperating with the resilience of the spring 2 507, the pushing tooth plate 506 can be effectively driven to perform reciprocating horizontal motion to quantitatively push the plastic inside the guide box 3.

[0039] Motor 1 207 and motor 2 503 in the present application are both common electrical devices in the prior art, and the present application will not elaborate on their models or internal structures.

[0040] Working principle: plastic particles are introduced into the interior of the screening box 201 through the feed port 4, and the operation of motor 1 207 is turned on to rotate the fan-shaped gravity block 208. The gravity force of the rotation of the fan-shaped gravity block 208 effectively makes the shaking plate 203 slide up and down in the inner wall of the screening box 201. When the shaking plate 203 slides up and down, it will drive the hydraulic rod 202 and spring 1 204 to reciprocate and retract, thereby effectively driving the filter plate 205 to reciprocate and swing up and down with the fixed rod 206 as the center of the circle, so that larger particles of plastic are filtered out from the discharge port of the screening box 201 through shaking, and plastics of the required particle size will pass through the filter plate 205 and fall into the interior of the guide box 3. At this time, the operation of motor 2 503 is turned on and its speed is set. When the gear 504 with the meshing teeth rotates to the surface of the pushing tooth plate 506, the pushing tooth plate 506 will be driven to slide through the meshing force, and the pushing tooth plate 506 slides to pull the spring 2 507 to stretch and deform. During the sliding process, the material inside the guide box 3 will be pushed. When the smooth part of the gear 504 rotates to the surface of the pushing tooth plate 506, the pushing tooth plate 506 is no longer restricted by the meshing force. At this time, the spring 2 507 will contract and pull the pushing tooth plate 506 back to its original position. The material is pushed to the outer surface of the conveyor belt 7 by pushing the tooth plate 506. By connecting to an external power source, the transmission roller 6 rotates to drive the conveyor belt 7 for transmission, so that the device can achieve quantitative reciprocating pushing of materials forward, further making the device more practical.
