Detailed Description of the Preferred Embodiments

[0022] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of this utility model.

[0023] This utility model provides: a raw material crusher for plastic processing, as Figures 1-4As shown in the figure, it includes a crushing box 1 and a support block 4. The support block 4 is fixedly installed on the side of the crushing box 1. A protective cover 3 is slidably arranged on the upper surface of the crushing box 1. Two groups of support plates 6 are fixedly installed on the upper surface of the support block 4. On the side of the two groups of support plates 6 close to the protective cover 3, a mounting plate 18 is fixedly installed. On the side of the mounting plate 18 away from the protective cover 3, there is a moving component for driving the protective cover 3 to move;

[0024] A feed hopper 8 is installed through the upper surface of the protective cover 3. Inside the feed hopper 8, there is an auxiliary material blocking component for assisting in preventing crushed materials from splashing. The support block 4 is fixedly installed on the side of the crushing box 1. The servo motor 5 and the support plates 6 are supported by the support block 4 to ensure the stability of the movement process of the protective cover 3. At the same time, the support block 4 is not connected to the protective cover 3, so as to ensure that the protective cover 3 can move.

[0025] Preferably, the moving component includes a servo motor 5, a lead screw 7, a sliding block 11, and a connecting column 13. The servo motor 5 is bolted to the upper surface of the support block 4. The lead screw 7 is key-connected to the output end of the servo motor 5. The sliding block 11 is threadedly sleeved on the outer arc surface of the lead screw 7. The connecting column 13 is fixedly installed on the lower surface of the sliding block 11, and the other end of the connecting column 13 is fixedly connected to the protective cover 3. Starting the servo motor 5 drives the lead screw 7 to rotate. The sliding block 11 moves along the outer arc surface of the lead screw 7 through the thread. When the lead screw 7 moves, it drives the protective cover 3 to move through the connecting column 13, so as to cover the crushing box 1 with the protective cover 3 to prevent debris from flying out. At the same time, when a failure occurs in the crushing equipment inside the crushing box 1, starting the servo motor 5 can drive the protective cover 3 to close and open, avoiding the need for manual operation by the staff, thus further ensuring the personal safety of the staff.

[0026] Furthermore, the lead screw 7 is rotatably arranged between the servo motor 5 and the mounting plate 18, and the lead screw 7 is located on the corresponding surfaces of the two groups of support plates 6. Neither the lead screw 7 nor the mounting plate 18 contacts the feed hopper 8. The mounting plate 18 supports one end of the lead screw 7 to ensure that the lead screw 7 rotates in a horizontal state. And the lead screw 7 does not contact the two groups of support plates 6, so as to ensure that the lead screw 7 can rotate normally. Also, neither the lead screw 7 nor the mounting plate 18 contacts the feed hopper 8 to prevent the feed hopper 8 from affecting the normal rotation of the lead screw 7.

[0027] Even further, limit plates 12 are fixedly installed on both sides of the sliding block 11, and corresponding limit grooves 10 are opened on the corresponding surfaces of the two groups of support plates 6. The two groups of limit plates 12 are symmetrically arranged on both sides of the sliding block 11 and are clamped into the limit grooves 10 to limit the sliding block 11 and prevent the sliding block 11 from rotating along with the lead screw 7.

[0028] It should be noted that the auxiliary material baffle assembly includes a baffle 9 and a compression spring 14. There are two sets of the baffle 9 and the compression spring 14. The two sets of baffles 9 are rotatably arranged on the inner wall of the feed hopper 8. One end of each of the two sets of compression springs 14 is fixedly connected to the corresponding side of the inner wall of the feed hopper 8, and the other end of each of the two sets of compression springs 14 is fixedly connected to the corresponding baffle 9. The two sets of baffles 9 are arranged obliquely downward, and an upward force is provided to the baffle 9 through the two sets of compression springs 14. When plastics are put into the feed hopper 8, the gravity of the plastics presses down the two sets of baffles 9 and enters the crushing box 1. When the feeding of plastics stops, the two sets of baffles 9 rotate upward under the action of the two sets of compression springs 14, thereby reducing the gap between the two sets of baffles 9, so as to further prevent debris from flying out through the feed hopper 8.

[0029] Specifically, clamping protrusions 15 are fixedly installed at both bottom ends of the protective cover 3, and clamping grooves 16 corresponding to the clamping protrusions 15 are formed on both sides of the crushing box 1. The protective cover 3 is limited by clamping the two sets of clamping protrusions 15 into the corresponding clamping grooves 16, and at the same time, it is ensured that the protective cover 3 can move horizontally.

[0030] In addition, a number of crushing motors 2 are bolted to the side of the crushing box 1, and a number of crushing columns are rotatably arranged inside the crushing box 1. The plastics are crushed by driving the number of crushing columns inside the crushing box 1 through the number of crushing motors 2.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
