[0005] During the recovery process, plastic bags float due to their light texture, which makes the contact points between the plastic bags and the two crushing rollers insufficient, which is not conducive to ensuring the crushing efficiency of the plastic bag recovery device. Therefore, it is necessary to design a recovery device with a pressing function for crushing plastic bags to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that during the recovery operation, due to the light texture of the plastic bag, floating phenomenon will occur, resulting in insufficient contact points between the plastic bag and the two crushing knife rollers, which is not conducive to ensuring the crushing efficiency of the plastic bag recovery device.

[0025] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0026] The first implementation method:

[0027] Figure 1-3 , Figure 6-7 A retrieval device for crushing plastic bags is shown, comprising a crushing frame 1, with crushing knife rollers 4 installed on both the front and rear sides of the inner end of the crushing frame 1, vertical poles 5 symmetrically fixedly connected to the left and right ends of the crushing frame 1, a rotating cross bar 6 installed between the two vertical poles 5, a mesh hollow shaft 7 fixedly connected to the outer end of the rotating cross bar 6, a joint rotating plate 8 fixedly connected to the lower end of the mesh hollow shaft 7, a plurality of arc-shaped hook rakes 9 fixedly connected to the front end of the joint rotating plate 8 equidistantly from left to right, and four-position air supply ports 10 fixedly connected to the upper inner wall of the mesh hollow shaft 7.

[0028] Figure 1-3 , Figure 6-7It is shown that the vertical pole 5 at the left end is externally connected to a drive motor 12, the output end of the drive motor 12 is connected to the rotating cross bar 6, the crushing knife roller 4 is externally connected to a second motor, the vertical pole 5 at the right end is externally connected to a fan 11, the output end of the fan 11 extends to the mesh hollow shaft 7 and is connected to the four-way air supply port 10, the lower end of the crushing frame 1 is fixedly connected to a feed port 3, the two crushing knife rollers 4 are meshed with each other, and the outer end of the crushing frame 1 is fixedly connected to a plurality of support legs 2, and the plurality of support legs 2 are located at the four corners outside the crushing frame 1.

[0029] Figure 1-3 , Figure 6-7 The present invention shows that the motor is used to drive the crushing rollers 4 to mesh and rotate, and the plastic bags put into the crushing frame 1 are crushed and recovered. During the recovery process, the plastic bags are light in texture and will float, so that the contact points between the plastic bags and the two crushing rollers 4 are not sufficient. Therefore, a rotating cross bar 6 that can be rotated by a driving motor 12 is provided between the two crushing rollers 4. When the rotating cross bar 6 rotates between the two crushing rollers 4, the associated rotating plate 8 under the crushing rollers 4 cooperates with a plurality of arc-shaped hook rakes 9 to rotate counterclockwise between the two crushing rollers 4, so that the arc-shaped hook rakes 9 are rotated. The rake 9 can generate downward pressure on the plastic bags that float up during the feeding process, which helps to make the contact points between the plastic bags and the two crushing knife rollers 4 sufficient, which is beneficial to ensuring the crushing efficiency of the plastic bag recovery device. At the same time, when the rotating cross bar 6 rotates, a four-directional air supply port 10 is also provided in the rotating cross bar 6. The four-directional air supply port 10 can blow gas outward in multiple ranges, so that the plastic bag fragments attached and entangled on the joint rotating plate 8 and the arc-shaped hook rake 9, as well as the meshing point between the two crushing knife rollers 4, can be blown away, so as to avoid a large amount of fragments adhering to the outside, thereby affecting the feeding efficiency of the plastic bag fragments.

[0030] The second implementation method:

[0031] Figure 2 , Figure 4-5 A retrieval device for crushing plastic bags is shown, wherein a plurality of sharp-angled hooks 14 are fixedly connected to the lower end of the arc-shaped hook rake 9, and the plurality of sharp-angled hooks 14 are arranged equidistantly from front to back. Meanwhile, when the arc-shaped hook rake 9 rotates following the associated rotating plate 8, a plurality of sharp-angled hooks 14 can be arranged under the arc-shaped hook rake 9 during the process of pressing the plastic bag downward. The sharp-angled hooks 14 can improve the connectivity between the arc-shaped hook rake 9 and the plastic bag, and prevent the plastic bag from escaping from the pressing area of ​​the arc-shaped hook rake 9. At the same time, the plastic bag can be hooked, and the crushing knife roller 4 can be more efficient when continuously crushing the plastic bag.

[0032] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
