[0021] The terms "first", "second", etc. are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features.

[0022] As Figures 1-9As shown, the ABS plastic purifier shell injection processing device provided by the embodiment of the application comprises an injection molding machine body 100, a storage barrel 200, a feeding pipe 201, a material leveling plate 407, a material carrying plate 700 and a second spring 701. The storage barrel 200 is arranged at the hopper feeding end of the injection molding machine body 100. The material carrying plate 700 is arranged at the inner side of the storage barrel 200. The second spring 701 is arranged at the lower end of the material carrying plate 700. The feeding pipe 201 is arranged at the feeding end of the storage barrel 200, and the lower end of the feeding pipe 201 is located at the upper end inside the storage barrel 200. A plurality of material leveling plates 407 are uniformly arranged outside the lower end of the feeding pipe 201. The feeding pipe 201 is used for storing materials in the storage barrel 200 or conveying materials into the hopper of the injection molding machine body 100. The plurality of material leveling plates 407 can rotate circumferentially and vertically lift relative to the feeding pipe 201.

[0023] In the embodiment, the ABS plastic purifier shell needs to be injected before the ABS plastic particles are transported. The ABS plastic particles are transported to the hopper and then enter the barrel. Then, under the heating of the barrel and the pushing of the screw, the ABS plastic particles enter the mold to be cooled and formed. The ABS plastic particles are generally stored in the storage barrel 200 before being transported to the hopper. The dried ABS plastic particles outside can be transported to the storage barrel 200 through the feeding pipe 201 for storage. When the ABS plastic particles are stored in the storage barrel 200, they will fall on the upper end of the load plate 700. As the amount of ABS plastic particles on the upper end of the load plate 700 increases, the pressure on the load plate 700 increases, causing the load plate 700 to move vertically downward in the storage barrel 200 and compress the second spring 701 at the lower end. When the load plate 700 moves downward to the preset position, the feeding pipe 201 no longer transports ABS plastic particles. At this time, the lower end of the feeding pipe 201 is located inside the upper end of the ABS plastic particles in the storage barrel 200. Since the second spring 701 is compressed, the second spring 701 will generate an upward pushing force due to deformation. The pushing force acts on the bottom end of the load plate 700, causing the load plate 700 to be in a state of force balance at this time. When the stored ABS plastic particles need to be transported, the feeding pipe 201 transports the material into the hopper of the injection molding machine body 100. Since the lower end of the feeding pipe 201 is inserted into the inside of the upper end of the ABS plastic particles, the ABS plastic particles at this position are sucked by the feeding pipe 201 to form a recess. Since the ABS plastic particles are dried and heated, some of the ABS plastic particles have a certain degree of stickiness, which may cause mutual bridging, resulting in the ABS plastic particles at this position failing to slide and fill the recess after being sucked. Since the amount of missing ABS plastic particles is small, the downward force on the load plate 700 at this time is not significantly reduced, causing the second spring 701 to have a small deformation recovery amount and unable to push the load plate 700 to move upward by a significant height, thereby failing to achieve the upward movement of the material in the recess and contact with the bottom end of the feeding pipe 201 for replenishment. At this time, the plurality of flat plates 407 rotate circumferentially and vertically lift relative to the feeding pipe 201, that is, the plurality of flat plates 407 rotate circumferentially and vertically lift at the recess, which can move the ABS plastic particles around the recess towards the middle and fill the recess for timely replenishment. At this time, the feeding pipe 201 can avoid flow interruption during suction. After the ABS plastic particles at this height are sucked by the above method, the flat plates 407 cannot replenish the recess at this time, but the missing ABS plastic particles reach a certain weight, so the load plate 700 vertically moves upward under the pushing force of the second spring 701 and reaches a position balance. At this time, the upper end of the ABS plastic particles contacts the lower end of the feeding pipe 201, achieving self-replenishment and avoiding flow interruption. When the material is reduced too much, the loading plate 700 moves vertically upward under the action of the second spring 701 and reaches a position balance, and at this time, the upper end of the ABS plastic particles contacts the lower end of the feeding pipe 201, realizing self-feeding and avoiding flow interruption; when the material reduction is not much and the material in the recess is bridged, the multiple flat plates 407 rotate circumferentially and vertically lift relative to the feeding pipe 201, that is, the multiple flat plates 407 rotate circumferentially and vertically lift at the recess, which can move the ABS plastic particles around the recess to the middle and fill the recess in time, thereby avoiding flow interruption when the feeding pipe 201 is drawing, compensating for insufficient vertical displacement of the loading plate 700, and ensuring that the material input into the hopper will not be interrupted to ensure the continuity and efficiency of injection molding.

[0026] As shown in Figure 5 , Figure 6 and Figure 9As shown, the outer side of the feeding pipe 201 is coaxially fixed with a fixing ring 500, the bottom end of the fixing ring 500 is vertically fixed with a driving rod 501, the upper end of the sleeve pipe 406 is shaped and processed into a bevel part, and the bottom end of the driving rod 501 is always in contact and connection with the bevel part of the sleeve pipe 406.

[0027] In the embodiment, when the sleeve 403 rotates relative to the feeding pipe 201, the sleeve pipe 406 rotates relative to the feeding pipe 201 through the first spring 404 and the connecting ring 405, the sleeve pipe 406 rotates relative to the fixing ring 500 because the fixing ring 500 and the driving rod 501 are fixed relative to the feeding pipe 201, and the sleeve pipe 406 vertically moves downward relative to the driving rod 501 because the bottom end of the driving rod 501 always contacts and connects with the bevel part of the sleeve pipe 406, the plurality of flat material plates 407 synchronously vertically move downward relative to the driving rod 501 when the bottom end of the driving rod 501 moves from low to high on the bevel part of the sleeve pipe 406, the sleeve pipe 406 vertically moves upward relative to the driving rod 501 under the pushing of the first spring 404 which restores deformation, the plurality of flat material plates 407 synchronously vertically move upward relative to the driving rod 501, the plurality of flat material plates 407 reciprocating vertically move upward under the rotation of the sleeve 403, and the plurality of flat material plates 407 reciprocating vertically move upward while rotating, which can move the ABS plastic particles around the recesses to the middle, fill the recesses in time, avoid the flow interruption of the feeding pipe 201 when drawing material, compensate for the insufficient vertical displacement of the material loading plate 700, ensure that the material input into the hopper will not be interrupted, and ensure the continuity and efficiency of injection molding.

[0031] In this embodiment, the material loading plate 700 is supported by the second spring 701. When the material is reduced, the material loading plate 700 moves vertically upward under the thrust of the second spring 701 and reaches a position balance. At this time, the upper end of the ABS plastic particles is in contact with the lower end of the feeding pipe 201, realizing self-feeding and preventing flow interruption.

[0032] As shown in Figure 4 , the upper end of the feeding pipe 201 is fixedly communicated with the discharge end of the external storage bin. The feeding pipe 201 is fixedly installed with an electromagnetic valve 202.
