[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figures 1-6As shown, the utility model provides a crushing device for producing plastic particles, comprising a bottom plate 1, a support frame 2 is mounted on the top surface of the bottom plate 1, a crushing mechanism 8 is mounted on the support frame 2, and an anti-blocking mechanism 6 is mounted at the discharge port of the crushing mechanism 8;

[0030] Among them, a vibration component 5 is installed between the bottom plate 1 and the crushing mechanism 8;

[0031] Furthermore, the crushing mechanism 8 and the vibration assembly 5 are respectively identical in structure and working principle to the crushing mechanism and the vibration mechanism in the existing utility model patent for a crushing device for producing plastic particles (publication number: CN219404935U), and will not be described in detail here;

[0032] Furthermore, a control panel 3 is mounted on the outer wall of the support frame 2. The control panel 3 is connected to all the electrical devices in the device through guides and controls the operation of the electrical devices.

[0033] The anti-clogging mechanism 6 includes a mounting frame 601 and a filter plate 606. The side wall of the filter plate 606 is evenly provided with a plurality of sliding grooves 609. A plurality of screening grooves 607 are evenly provided between two adjacent sliding grooves 609.

[0034] Multiple air pumps 608 are evenly installed on the side wall of the filter plate 606, and the air outlet end of the air pump 608 is connected to the sliding groove 609;

[0035] Sliding blocks 605 are slidably installed in the plurality of sliding slots 609 , and a connecting plate 604 is installed on one side of the sliding blocks 605 away from the air pump 608 ;

[0036] The sliding slot 609 is connected to the adjacent screening slot 607;

[0037] A mounting frame 601 is installed on the side of the filter plate 606 away from the air pump 608. Slide grooves 602 are respectively provided on the left and right sides of the inner cavity of the mounting frame 601. A connecting plate 604 is slidably installed between the two slide grooves 602.

[0038] A plurality of springs 603 are evenly installed on the side of the connecting plate 604 away from the sliding block 605, and the side of the plurality of springs 603 away from the connecting plate 604 is connected to the inner cavity side wall of the mounting frame 601;

[0039] A collecting frame 4 is installed in the middle of the top surface of the bottom plate 1, and a material blocking frame 10 is installed on the bottom surface of the screening tank 607;

[0040] Among them, the material blocking frame 10 is used to limit the discharging of materials, and the collecting frame 4 is used to collect materials;

[0041] In this embodiment, when the screening slot 607 is clamped with large plastic particles, and these large plastic particles are clamped more tightly under the action of the vibration component 5, the air pump 608 is started, and the air pump 608 will inflate the interior of the sliding slot 609. As the air pump 608 injects gas, the sliding block 605 will be pushed by the gas to slide in the sliding slot 609. At this time, the multiple sliding blocks 605 will drive the connecting plate 604 to slide into the inner cavity of the installation frame 601, and at the same time squeeze the spring 603 to contract;

[0042] When the sliding block 605 slides and contacts the closed sliding slot 609 and the sieving slot 607, high-pressure gas will be poured into the sieving slot 607, and the particles in the sieving slot 607 will be discharged from the sieving slot 607 under the high-pressure gas flow, thereby unblocking the sieving slot 607.

[0043] Finally, the inflation of the air pump 608 is stopped, and the sliding block 605 and the connecting plate 604 will be quickly reset under the action of the spring 603, closing the connection between the sliding groove 609 and the screening groove 607 to prevent particles from entering the sliding groove 609.

[0048] In this embodiment, when the device generates a large amount of dust during pulverization, the opening of the nylon bag and the inner wall of the annular groove 705 are first sealed with iron wire;

[0049] Then, the exhaust fan 703 is started through the control panel 3. The exhaust fan 703 pours the fine powder in the pulverizing mechanism 8 into the nylon bag on the connecting ring 704 through the filter 702 and the exhaust fan 703, thereby processing the fine dust in the pulverizing mechanism 8.
