[0043] Specifically, when the carton is placed in the body 1, the push rod 27 is manually slid, so that the push rod 23 connected to one end of the push rod 27 drives the sliding block 24 to slide together, so that the size of the carton can be aligned, then the push rod 27 is pushed again, so that the push rod 23 drives the sliding block 24 to push the carton placed in the body 1 to the pushing-out mechanism 3 in the body 1, which is designed to save the alignment and arrangement of the stacked cartons during processing.

[0046] Referring to Figure 3 and Figure 4The collecting mechanism 7 comprises a collecting box 71 which is designed to collect the ejected paper blocks and can uniformly collect the paper blocks. The bottom of the collecting box 71 is fixedly connected to the top of the two guide rails 6. The inner walls of the collecting box 71 are rotatably connected with two support columns 72. The support columns 72 can smoothly rotate through the support of the collecting box 71. The outer portions of the two support columns 72 are rotatably connected with two rotating plates 73 which are designed to prevent the paper blocks from falling and being concentrated inside the collecting box 71, so that the paper blocks will tilt to one side when the paper blocks are stacked and will scatter on the inner bottom wall of the machine body 1. The adjacent sides of the rotating plates 73 are rotatably connected with connecting columns 74 which are designed to provide good rotating ability. The connecting columns 74 are connected between the two rotating plates 73, so that the rotating plates 73 can smoothly rotate. The inner bottom wall of the collecting box 71 is fixedly connected with a guide column 75 which can provide good guiding ability through the support of the collecting box 71. The outer portion of the guide column 75 is sleeved with a return spring 76 which is designed to provide good return ability. The guide column 75 can prevent the return spring 76 from deviating when being compressed or stretched. The top of the return spring 76 is located at the bottom of the connecting column 74. The two rotating plates 73 are connected with the two support columns 72 through the connecting column 74, so that the two rotating plates 73 can be placed flat, and the return spring 76 will be pressed downward.

[0047] Specifically, the collecting box 71 can collect the ejected paper blocks. The support columns 72 and the connecting columns 74 provide rotation, so that the two rotating plates 73 can be rotated. The return spring 76 supported by the guide column 75 at the bottom can make the rotating plates 73 present an upward triangular shape. When the paper blocks fall during processing, the two rotating plates 73 can be pressed through the gravitational force of the stacked paper blocks. The return spring 76 will be compressed, so that the paper blocks will slide to the two sides inside the collecting box 71. This design can perfectly collect the paper blocks. When the paper blocks inside the collecting box 71 are uniformly collected, the two rotating plates 73 will be lifted again through the released pressure of the return spring 76, which is convenient for use next time.

[0048] Working principle: when the carton is placed in the body 1, the push rod 27 is manually slid, the push rod 27 at one end of the push rod 23 is driven to slide the sliding block 24, and the size of the carton is aligned. Push the push rod 27 again, the push rod 27 drives the push rod 23 to push the sliding block 24 to the inside of the push-out mechanism 3 in the body 1. At this time, the pneumatic cylinder 31 in the push-out mechanism 3 starts to work, its output end drives the connecting plate 32 to press down, and the vertical cutter 33 in the alignment hole 34 on the connecting plate 32 pushes out the paper block in the carton. When placing the carton, the sliding rod 51 slides outside the connecting rod 4, so that the carton can be well supported, and then the positioning plate 53 adjusts the horizontal distance to support and fix the two sides of the carton. At the same time, the rear end of the carton is fixed by sliding the positioning plate 53, so as to ensure that the carton will not shift during processing. After fixing, push the push rod 27 again to drive the sliding block 24 to push the other side of the carton, so that the carton is completely attached to the inside of the positioning plate 53. In this process, as described above, when the carton enters the body 1, the operator manually slides the push rod 27, which drives the push rod 23 and the sliding block 24 to move and adjust to the position matching the size of the carton. Then, push the push rod 27 again to push the carton to the push-out mechanism 3. The vertical cutter 33 is fixed in different alignment holes 34 by screw connection, so as to accurately align with the support block of the carton, and then the pneumatic cylinder 31 is started to push the connecting plate 32 to press down, and the vertical cutter 33 on the connecting plate 32 aligns with the paper block in the carton and pushes it out. Before processing, the sliding rod 51 slides on the connecting rod 4, drives the positioning plate 53 to move and adjust to the appropriate position to support and fix the carton. The positioning plate 53 can fix the carton from both sides and the rear end to prevent it from shifting during processing. When the carton is fixed, push the push rod 27 again, and the sliding block 24 continues to push the carton to tightly fit on one side of the positioning plate 53. During the whole processing, the guide rail 6 ensures the smooth movement of the carton;

[0049] When the paper box is placed inside the machine body 1, the paper pieces pushed out fall into the collecting box 71. The bottom of the collecting box 71 is fixedly connected to the top of the two guide rails 6, facilitating sliding out of the unified collection of paper pieces during processing, and in use, the support column 72 can drive the rotating plate 73 to rotate. Meanwhile, the top of the reset spring 76 is located at the bottom of the connecting column 74. In the initial state, the reset spring 76 is in a natural state, and the two rotating plates 73 are in an upward triangular shape under the action of the reset spring 76, forming a concentrated collection area. When the paper pieces are pushed out by the vertical cutter 33 and fall into the collecting box 71, the paper pieces will slide to both sides of the collecting box 71 under the action of their own gravity. With the continuous falling and accumulation of the paper pieces, the paper pieces will generate downward pressure on the rotating plate 73. This pressure is transmitted to the connecting column 74 through the rotating plate 73, causing the rotating plate 73 to reset to form a flat surface, and the downward movement of the connecting column 74 compresses the reset spring 76, causing it to generate upward elastic force. When the gravity and pressure of the paper pieces exceed the elastic force of the reset spring 76, the rotating plate 73 will gradually rotate downward, allowing the paper pieces to be evenly distributed on both sides of the collecting box 71, preventing the paper pieces from being concentrated and stacked on one side of the collecting box 71, causing the paper pieces to fall off. When the paper pieces inside the collecting box 71 need to be cleaned, the operator can pause the operation of the paper shell waste cleaning machine and take out the collected paper pieces. After taking out, the reset spring 76 will automatically return to the natural state under the condition of losing the pressure of the paper pieces, and drive the rotating plate 73 back to the upward triangular shape of the top position through the connecting column 74, preparing for the next collection of paper pieces.

[0050] 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 make equivalent replacements of some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
