The shape and structural design of the paper box are often determined by the shape characteristics of the packaged goods. Therefore, there are many styles and types, including rectangular, square, polygonal, special-shaped paper boxes, cylindrical, etc. The manufacturing process is basically the same, that is, selecting materials - designing icons - making templates - stamping - joining them into boxes. In this process, a lot of scraps will be generated; these scraps can be recycled and reused. Generally, the scraps will be crushed first to facilitate their recycling.

An electric telescopic rod is installed at the lower part of the box body, and the electric telescopic rod can drive the push plate to compress the crushed carton scraps. The compressed carton scraps are stored in a drawer. The feed port of the device is located above the box body, which can ensure smooth feeding. When there are enough carton scraps, the sliding door is opened to ensure uniform feeding. Finally, the crushed carton scraps are compressed by the electric telescopic rod, the volume becomes smaller, and the discharge is simple.

[0004] However, in the above arrangement, the crushed carton scraps will directly fall to the bottom of the box. The carton scraps are of different sizes and are only crushed once between the crushing knives before entering the bottom of the box for discharge and collection. This can easily lead to insufficient crushing of the carton scraps. Summary of the invention

[0011] With this arrangement, when in use, the carton scraps are placed in the feeding bin, and when the stepper motor is started, the lead screw is driven to rotate, that is, the slide plate is driven to move left and right along the slide bar, and then the feeding bin can be driven to move left and right above the crushing box, thereby ensuring the uniformity of feeding when the carton scraps are crushed, and effectively improving the crushing efficiency.

[0046] The above scheme is adopted: when the loading bin 2 moves left and right to load the material, it will drive the support plate 401 to move left and right, thereby driving the wheel plate 402 to roll left and right along the wheel track 404, and then driving the flipping plate 5 at the other end of the support rod 403 to rotate and move left and right along the discharge port 102. Therefore, the self-rotation and left and right movement of the flipping plate 5 to flip the material are carried out simultaneously, which improves the full flipping operation of the paper box scraps at the discharge port 102. On the one hand, the crushed materials at the bottom of the crushing box 101 are allowed to move between each other, which is convenient for the crushing rod 8 to more fully perform the crushing work. On the other hand, it is convenient to flip and scrape the discharge mesh plate 7 to avoid its blockage, which facilitates its faster discharge, thereby helping to improve work efficiency.

[0048] The above scheme is adopted: when the long flap 501 on the flip plate 5 rotates to the discharge mesh plate 7, the discharge mesh plate 7 will be pressed tightly. At this time, the spring 702 is driven to shrink and deform to make the discharge mesh plate 7 move downward, until the short flap 502 rotates to the discharge mesh plate 7, the spring 702 will be reset and drive the discharge mesh plate 7 to reset, so as to facilitate the discharge mesh plate 7 to shake up and down, which is more conducive to the rapid discharge of the discharge mesh plate 7.

[0049] refer to Figure 4 , Figure 6 and Figure 8As shown, the crushing assembly also includes a positioning ring 503, and the positioning ring 503 is located in the middle of the flipping plate 5. The front and rear outer walls of the positioning ring 503 are fixedly connected with an axle rod 504, and the axle rod 504 is connected to the flipping plate 5 through a bearing.

The receiving hole 802 is matched and connected with the rotating rod 6, and the surface of the crushing rod 8 is sleeved with evenly distributed crushing blades 801.

[0050] The above scheme is adopted: the shaft rod 504 is connected to the bearing of the turning plate 5, so that when the turning plate 5 rotates, it will not drive the positioning ring 503 to rotate, but will only drive the positioning ring 503 to move left and right, thereby improving the stability of the connection between the positioning ring 503 and the crushing rod 8. On the one hand, when the rotating rod 6 rotates, the limiting effect of the positioning block 803 is convenient to drive the crushing rod 8 to rotate, and then it is convenient to drive the crushing blade 801 to rotate to further crush the scraps of the paper box. On the other hand, it is convenient to drive the crushing rod 8 and the crushing blade 801 to move left and right along the rotating rod 6, so that the crushing efficiency is more sufficient.

[0057] Furthermore, the wheel plate 402 can be set to a gear shape, and the wheel rail 404 can be correspondingly set to a toothed chain shape. The gear-shaped wheel plate 402 and the toothed chain-shaped wheel rail 404 are meshingly connected. The advantage of this setting is that it is beneficial to improve the stability of the connection between the wheel plate 402 and the wheel rail 404, which makes it easier for the wheel plate 402 to roll stably along the wheel rail 404, and then drives the flipping plate 5 to perform stable self-rotation movement.

It should be noted that the fluid can be either gas or liquid.

[0059] This setting has the following effects:

[0060] First, if the fluid extraction member is set as a vacuum cleaner, on the one hand, the broken paper scraps of smaller size can be recycled (larger paper scraps can still be discharged through the discharge mesh plate 7), and on the other hand, smaller debris particles can be prevented from flying and polluting the working environment.

[0061] Second, if the fluid supply member is an air pump, if the discharge mesh plate 7 is blocked, the discharge mesh plate 7 can be cleared to a certain extent by blowing air through the air pump.

[0062] Thirdly, if the fluid supply member is a water pump, an appropriate amount of water can be supplied, thereby facilitating improving the crushing efficiency.

[0063] Fourthly, the positioning ring 503 reciprocates on the rotating rod 6 to clean the through hole and reduce the blockage of the through hole.

[0064] Working principle of the present invention:

[0065] When in use, the carton scraps are placed in the loading bin 2, and the stepper motor 201 and the rotating motor 303 are started. At this time, the slide plate 4 drives the loading bin 2 to move left and right along the slide bar 203, and the materials are evenly fed into the crushing box 101 through the bottom of the loading bin 2 and the slide plate 4. The two sets of spiral blades 301 rotate to fully crush the materials, and the support plate 401 also moves with the slide plate 4, driving the wheel plate 402 to roll left and right along the wheel track 404, and then driving the flipping plate 5 at the other end of the support rod 403 to rotate and move left and right along the discharge port 102. Therefore, the flipping plate 5 rotates and flips the materials at the same time, which improves the full flipping operation of the carton scraps at the discharge port 102, which is beneficial to prevent material blockage and make the powder more sufficient. At the same time, through the positioning ring 503, the shaft rod 504, The accommodating hole 802, the positioning block 803 and the positioning groove 601 enable the rotating rod 6 to drive the crushing rod 8 to rotate and move, that is, drive the crushing blade 801 to rotate to further crush the scraps of the carton scraps, thereby improving the crushing efficiency. At the same time, the long flap 501 and the short flap 502 press against the discharge mesh plate 7 in turn, that is, when the long flap 501 rotates to the discharge mesh plate 7, it will press against the discharge mesh plate 7. At this time, the spring 702 is driven to shrink and deform, causing the discharge mesh plate 7 to move downward, until the short flap 502 rotates to the discharge mesh plate 7, which will reset the spring 702 and drive the discharge mesh plate 7 to reset, thereby facilitating the discharge mesh plate 7 to shake up and down, which is more conducive to the rapid discharge of the discharge mesh plate 7. Finally, the fully crushed carton plastic will fall into the collection box 103.
