[0002] Paper bags are a widely used packaging material, mainly used to load, protect, transport and display various commodities. They are usually made of paper or paper composite materials, and are lightweight, recyclable and environmentally friendly. The production process of paper bags involves multiple links, including material selection, printing, cutting, folding, gluing, punching, etc.

[0003] When punching paper bags, holes are usually punched at the handles to facilitate people to take the paper bags. However, in the production of paper bags, in order to ensure the production speed of paper bags, cutting blades are usually installed on the sticks to punch the paper bags in transportation when rotating. However, the remaining materials cut by punching are generally not completely cut off to prevent the remaining materials from running around and affecting the working environment. They also need to be handled separately, and their recycling is more cumbersome.

[0028] A cleaning motor 5 and a limit frame 10 are fixedly arranged on the inner wall of the inner shell 3. The cleaning motor 5 is a servo motor to assist in rotating the rotation speed of the rotating stick 2 to control the rotation speed of the cleaning disk 6. The output end of the cleaning motor 5 is fixedly connected to the cleaning disk 6. The center rod 8 moves through the inner side of the limit frame 10. A limit block 9 is fixedly arranged on the outer side of the center rod 8. One side of the limit block 9 contacts one end of the limit frame 10.

[0029] By setting the cleaning disk 6, when the rotating roller 2 cuts and punches the packaging paper bag being conveyed, the cut residual materials are collected to prevent the residual materials from running around, and the cleaning disk 6 rotates one circle when the rotating roller 2 rotates one circle, and the cut residual materials are automatically collected, and the degree of automation is relatively high. Moreover, through the movable connection of the telescopic rod 12, when the suction cup 121 contacts the residual materials, the pressure between the suction cup 121 and the residual materials can be increased, so that the residual materials are brought into the rotating roller 2.

[0030] A rotating disk 13 is fixedly provided at the output end of the cleaning motor 5 , and a protruding rod 14 is fixedly provided at an eccentric position of one end of the rotating disk 13 close to the cleaning disk 6 , so as to ensure that the protruding rod 14 revolves around the axis of the rotating disk 13 .

[0031] The inner walls on both sides of the inner shell 3 are provided with limiting slide grooves 18, and sliding plates 15 are movably provided inside the two limiting slide grooves 18. An inclined plate 16 is fixedly provided at the lower end of the sliding plate 15, and a push plate 17 is fixedly provided at the upper end of the sliding plate 15. The push plate 17 is mainly used to push out the residual material on the suction cup 121 to separate the residual material from the suction cup 121.

[0032] Two vertical plates 19 are fixed on the upper end of the sliding plate 15, and a tension spring 20 is fixed on one end of the vertical plate 19. Two fixed plates 21 are fixed on the inner wall of the inner shell 3, and the ends of the tension springs 20 are fixedly connected to one side of the fixed plate 21 to ensure that the sliding plate 15 can be reset.

[0033] An L-shaped plate 151 is fixedly provided at one end of the sliding plate 15, and the outer side of the protruding rod 14 abuts against the L-shaped plate 151. Through the arrangement of the sliding plate 15 and the turntable 13, after the suction cup 121 brings out the residual material, the residual material is automatically pushed down, and through the arrangement of the inclined plate 16, the residual material is prevented from running out of the rotating roller 2, and through the arrangement of the conical surface 4 on the inner shell 3, the residual material is automatically moved toward the discharge hole 22 after being pushed out, which is convenient for the automatic discharge of the residual material, further improving the degree of automation, and using fewer electrical components.

[0034] The sliding plate 15 is concavely arranged to ensure that the residual material falls onto the inclined plate 16 .

[0035] Working principle: the operator turns on the motor, so that the motor drives the rotating rod 2 to rotate, and then the rotating rod 2 drives the sponge layer 201 and the punching blade 202 to rotate, so that the punching blade 202 performs a punching operation on the packaging cardboard, and at the same time turns on the cleaning motor 5, the cleaning motor 5 drives the cleaning disk 6 and the rotating disk 13 to rotate, and the cleaning disk 6 drives the center rod 8 to move through the convex groove 7, and the center rod 8 is limited by the limit frame 10, so that the center rod 8 can only slide up and down, so that the center rod 8 drives the extension rod 11 to move, and then the extension rod 11 drives the telescopic rod 12 to move, and the telescopic rod 12 drives the suction cup 121 to move, so that the suction cup 121 absorbs the cut residual material;

[0036] At this time, the cleaning disc 6 continues to rotate, so that the convex curved groove 7 drives the center rod 8 to reset, and at the same time, the suction cup 121 drives the residual material to enter the rotating roller 2. At the same time, the rotating disc 13 drives the convex rod 14 to rotate, so that the convex rod 14 abuts the L-shaped plate 151, and the L-shaped plate 151 drives the sliding plate 15 to move. Through the setting of the limiting sliding groove 18, the sliding plate 15 moves parallel to the suction cup 121, and then the sliding plate 15 drives the pushing plate 17 to push the residual material on the suction cup 121 down, so that the residual material is separated from the suction cup 121, and then the residual material falls onto the inclined plate 16. Due to the movement of the sliding plate 15, the inclined plate 16 is completely above the punching blade 202, and then the residual material falls onto the conical surface 4 on the inner shell 3 through the inclined plate 16, so that the residual material is accumulated at the angle of the rotating roller 2, and then through the setting of the discharge hole 22, the residual material enters the collection box 23, completing the automatic recovery and centralized treatment of the residual material;

[0037] At this time, the turntable 13 continues to rotate, so that the protruding rod 14 is separated from the L-shaped plate 151, and the tension spring 20 is working, so that the tension spring 20 drives the vertical plate 19 to move toward the fixed plate 21, so that the sliding plate 15 is reset to facilitate the next waste material recovery preparation.
