DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] In order to solve the problem that when the plastic products of large volume and thickness are crushed, the distance between the crushing rollers 401 cannot be adjusted adaptively, the plastic products are prone to generate a large interaction force with the blades on the crushing rollers 401, thereby aggravating the wear of the blades and the large-volume plastic products are prone to be stuck between the adjacent two blades after being crushed into fragments by the crushing rollers 401, thereby affecting the subsequent crushing efficiency, the following embodiments are proposed.

[0025] The utility model provides a kind of crusher for breaking up plastic as shown in Figures 1 to 4 The utility model provides a kind of crusher for breaking up plastic as shown in

[0026] By setting the adjusting assembly 5 and the crushing assembly 4, the distance between the crushing assemblies 4 can be adjusted adaptively when the plastic products of different volume thicknesses pass between the crushing assemblies 4, so that the crushing assemblies 4 can effectively crush the plastic products while reducing the wear of the crushing assemblies 4; the adjusting assembly 5 can also detect the situation that the plastic fragments are stuck between the crushing assemblies 4, so as to promote the crushing assemblies 4 to automatically clean.

[0027] As shown in Figures 1-3 The adjusting assembly 5 includes a moving block 501, one end of the moving block 501 is provided with a spring 502, and the end of the spring 502 away from the moving block 501 is connected with a fixed plate 503. The crushing assembly 4 includes a crushing roller 401, and the outer side of the crushing roller 401 is uniformly provided with a crushing blade 402. When there is no plastic product between the crushing rollers 401 for crushing, the crushing blades 402 on the two crushing rollers 401 are in contact with each other. When there is a plastic product between the crushing rollers 401 for crushing, the crushing blades 402 on the two crushing rollers 401 cut and crush the plastic product, and a gap is formed between the crushing blades 402. The two ends of the crushing roller 401 are fixedly provided with a rotating shaft 403; the rotating shaft 403 is rotatably connected with the moving block 501, and the moving block 501 is provided with a circular through hole through which the rotating shaft 403 passes.

[0028] In use, the control center starts the motor 6, the motor 6 drives the crushing roller 401 to rotate through the rotating shaft 403, and then the plastic product is thrown into the two crushing rollers 401 through the feeding port 102. The crushing blades 402 on the crushing roller 401 cut and crush the plastic product, the plastic fragments fall onto the screening plate 3, the screening plate 3 screens the plastic fragments, the qualified plastic fragments fall into the receiving box 2 for collection, and the unqualified plastic fragments are again put into the crushing roller 401 through the feeding port 102 for secondary crushing.

[0029] During the crushing process, the plastic product passes between the two crushing rollers 401, and the crushing blades 402 on the two crushing rollers 401 move away from each other due to the presence of the plastic product, so that the crushing rollers 401 move away, and then the moving block 501 is driven to move through the rotating shaft 403. The moving block 501 compresses the spring 502, and the spring 502 generates a reverse elastic force, so as to ensure that the crushing blades 402 can adaptively cut and crush plastic products of different volume thicknesses, and reduce the wear of the crushing blades 402.

[0030] By setting the spring 502, when the plastic product is crushed by the crushing roller 401, the distance between the two crushing rollers 401 can be adaptively adjusted, the interaction force between the plastic product and the crushing blade 402 is reduced, the crushing blade 402 can be effectively crushed, and the wear of the crushing blade 402 is reduced; the compression amount of the spring 502 can be changed to determine whether the plastic fragments are stuck between the adjacent two crushing blades 402, and the rotation state of the two crushing rollers 401 is adjusted to remove the plastic fragments, so that the crushing roller 401 realizes automatic removal and ensures the subsequent crushing efficiency.

[0031] When the plastic product normally passes between the two crushing rollers 401, the spring 502 continuously generates a compression amount, and the compression amount continuously changes irregularly; when no plastic product passes between the two crushing rollers 401, the spring 502 does not generate a compression amount; the above two signals are transmitted to the control center, and the control center judges that the situation is normal operation.

[0032] When no plastic product passes between the two crushing rollers 401, the spring 502 still generates a compression amount, which represents that the plastic fragments are stuck between the crushing blades 402 of the crushing roller 401, at this time, the control center receives the signal and judges that the operation is abnormal, controls any motor 6 to stop rotating, and the other motor 6 continuously rotates, so that any crushing roller 401 is stationary, and the other crushing roller 401 keeps rotating, so that any crushing blade 402 can push out the plastic fragments stuck between the other crushing blade 402, thereby completing the removal; when the spring 502 does not generate a compression amount, it represents that the plastic fragments have been removed, and the control center controls the rotating motor 6 to stop rotating.

[0033] As shown in Figure 4 The machine body assembly 1 includes a machine shell 101, the top of the machine shell 101 is provided with a feeding port 102 above the crushing assembly 4, and the two sides of the machine shell 101 are provided with long through holes 103; the rotating shaft 403 passes through the long through hole 103 and can reciprocate in the long through hole 103. The plastic fragments are thrown into the crushing assembly 4 through the feeding port 102, and the long through hole 103 can support the movement of the crushing roller 401.

[0034] The working principle of the utility model is: first, the plastic product is put in, the control center starts the motor 6, the motor 6 drives the crushing roller 401 to rotate through the rotating shaft 403, and then the plastic product is thrown between the two crushing rollers 401 through the feeding port 102.

[0035] Secondly, the plastic products are crushed, the crushing blades 402 on the crushing rollers 401 cut and crush the plastic products, in the crushing process, the plastic products pass between the two crushing rollers 401, the crushing blades 402 on the two crushing rollers 401 move away from each other due to the existence of the plastic products, so that the crushing rollers 401 move away, and then the moving blocks 501 are driven to move by the shafts 403, the moving blocks 501 compress the springs 502, the springs 502 generate reverse elastic force, so that the crushing blades 402 can adaptively cut and crush plastic products of different volumes and thicknesses. When the plastic products normally pass between the two crushing rollers 401, the springs 502 continuously generate a compression amount, and the compression amount continuously changes irregularly; when no plastic products pass between the two crushing rollers 401, the springs 502 do not generate a compression amount; the above two signals are transmitted to the control center, and the control center judges that the situation is normal operation.

[0036] Then, the fragments are screened and collected, the plastic fragments fall on the screening plate 3, the screening plate 3 screens the plastic fragments, and the crushed qualified plastic fragments fall into the receiving box 2 for collection.

[0037] Then, the unqualified plastic fragments are crushed again, the unqualified plastic fragments are crushed again by the user by pulling out the screening plate 3 and re-feeding the unqualified plastic fragments into the crushing rollers 401 through the feeding port 102.

[0038] Finally, the plastic fragments are removed, when no plastic products pass between the two crushing rollers 401, the springs 502 still generate a compression amount, which represents that the plastic fragments are currently stuck between the crushing blades 402, at this time, the control center receives the signal and judges that the operation is abnormal, controls any motor 6 to stop rotating, and the other motor 6 continuously rotates, so that any crushing roller 401 is stationary, and the other crushing roller 401 keeps rotating, so that any crushing blade 402 can push out the plastic fragments stuck between the other crushing blade 402, thereby completing the removal; when the springs 502 do not generate a compression amount, it represents that the plastic fragments have been completely removed, and the control center controls the rotating motor 6 to stop rotating.

[0039] Finally, it should be noted that: the above only describes preferred embodiments of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
