[0002] Kraft paper bags are non-toxic, odorless, and pollution-free. They meet national environmental protection standards, have high strength and are highly environmentally friendly. They are one of the most popular environmentally friendly packaging materials in the world. Kraft paper bags made of kraft paper are increasingly widely used. When shopping in supermarkets, shopping malls, shoe stores, clothing stores, etc., there are generally kraft paper bags available, which is convenient for customers to carry the purchased items. Kraft paper bags are cut during the production process to make holes on the surface of kraft paper bags;

[0003] However, when cutting holes in kraft paper bags, a large amount of waste is generated. If it is not cleaned up, the waste will be scattered everywhere, and it needs to be cleaned up again manually, which increases the workload. In addition, when cutting holes in kraft paper bags, no pressing mechanism is provided, which makes it easy for the holes in the kraft paper bags to deviate, resulting in product damage. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example: Figure 1-3As shown, the utility model provides a kraft paper bag cutting device, including a box body 1, a support frame 2 is fixedly installed on the top of the box body 1, a first electric push rod 3 is fixedly installed on one side of the top of the box body 1, a push plate 31 is provided on one side of the first electric push rod 3, and the middle part of one side of the push plate 31 is fixedly installed on the driving end of the first electric push rod 3, the upper part of the box body 1 is provided with two symmetrically distributed first tooth plates 11, and the side of the box body 1 away from the first tooth plate 11 is provided with two symmetrically distributed second tooth plates 12, and two symmetrically distributed gears 13 are rotatably installed in the middle parts of the two box bodies 1, the first tooth plate 11 and the second tooth plate 12 are both meshed and connected with the gear 13, the lower part of the push plate 31 is fixedly installed on one end of the first tooth plate 11, and the opposite sides of the two second tooth plates 12 are fixedly installed with a baffle 14, the baffle 14 is slidably clamped on the upper part of the box body 1, and the lower part of the box body 1 is slidably provided with a collection box 15, and the inner lower surface of the support frame 2 is fixedly installed with a hole cutter body 21.

[0017] A screw rod 4 is rotatably installed on the upper part of the support frame 2, and positive and negative threads are provided at both ends of the screw rod 4. Symmetrically distributed sliders 41 are threadedly installed at both ends of the screw rod 4, and a second electric push rod 42 is fixedly installed at the bottom ends of the two sliders 41. A clamping plate 43 is provided at the bottom ends of the two second electric push rods 42, and the middle parts of the top ends of the two clamping plates 43 are fixedly installed on the driving end of the second electric push rod 42.

[0018] Two symmetrically distributed first slide grooves 111 are provided on the upper part of one side of the box body 1 close to the first tooth plate 11. The two first tooth plates 11 are slidably clamped in the first slide grooves 111, and both sides of the lower part of the push plate 31 are slidably clamped in the first slide grooves 111. By setting the first slide grooves 111, the first slide grooves 111 limit the push plate 31 and the first tooth plate 11, so that the push plate 31 is more stable when driving the first tooth plate 11 to move.

[0019] Two symmetrically distributed second slide grooves 121 are provided on the upper part of one side of the box body 1 close to the second tooth plate 12. The two second tooth plates 12 are slidably clamped inside the second slide grooves 121, and both sides of the baffle 14 are slidably clamped inside one side of the second slide grooves 121. By setting the second slide grooves 121, the second tooth plate 12 and the baffle 14 are limited by the second slide grooves 121, so that it is more stable when the second tooth plate 12 drives the baffle 14 to move.

[0020] A cavity 16 is formed at the lower portion of the box body 1 , and the collecting box 15 is slidably mounted at the lower portion of the cavity 16 .

[0021] Universal wheels 17 are fixedly installed at the four corners of the bottom end of the box body 1. By providing the universal wheels 17, the device as a whole is easy to move.

[0022] A limiting groove 22 is provided on the upper part of the support frame 2, and the two sliders 41 are slidably clamped inside the limiting groove 22. By setting the limiting groove 22, when the screw rod 4 rotates, the limiting groove 22 limits the slider 41, thereby driving the two sliders 41 to move relative to each other.

[0023] One end of the screw rod 4 passes through the support frame 2, and a handle 44 is fixedly installed on the end of the screw rod 4 passing through the support frame 2. By setting the handle 44, the screw rod 4 is driven to rotate by rotating the handle 44, that is, the two sliders 41 are driven to move relative to each other, so that the clamping plate 43 is located at the upper part of the kraft paper bag.

[0024] Working principle: in actual use, a kraft paper bag is placed on the top of the baffle 14, and a hole is made in the kraft paper bag through the hole cutter body 21. After the hole is made, the kraft paper bag is taken away, and the waste generated by the hole making will be retained on the top of the baffle 14. By starting the first electric push rod 3, the first push plate 31 is driven to move forward, that is, the first tooth plate 11 is driven to move forward, so that the gear 13 rotates, thereby driving the meshing second tooth plate 12 to move. At this time, the first tooth plate 11 and the second tooth plate 12 move in opposite directions, that is, the push plate 31 moves forward while the baffle 14 moves backward, so that the cavity 16 leaks out. Under the relative movement of the push plate 31 and the baffle 14, the push plate 31 pushes the waste retained on the upper surface of the baffle 14 away from the upper part of the baffle 14, so that it falls into the cavity 16 and then enters the collection box 15 for collection. The waste inside the collection box 15 can be removed by pulling out the collection box 15.

[0025] After placing the kraft paper bag on the upper part of the baffle 14, the screw 4 is driven to rotate by turning the handle 44, that is, the two sliders 41 are driven to move relative to each other, so that the clamping plate 43 is located on the upper part of the kraft paper bag, and the second electric push rod 42 is started to drive the clamping plate 43 to move downward to clamp and fix the kraft paper bag, and then the hole cutter body 21 is started to cut a hole in the clamped kraft paper bag.

[0026] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
