[0002] During the processing and production of plastic bags, the required arc-shaped notches need to be cut out on their sides. However, the cut leftovers are sometimes adsorbed on the plastic bags due to static electricity, causing the cut leftovers to be carried everywhere, requiring workers to spend a lot of extra time cleaning up later, which is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of the utility model is to provide a plastic bag residual material cutting device to overcome the above-mentioned defects in the prior art.

[0004] A device for removing residual material from plastic bags comprises a frame, a cutting mechanism and a cleaning mechanism. The top of the frame is provided with several support plates. The cutting mechanism is provided with two and is arranged on a fixed plate of the frame. The cutting mechanism is used to remove residual material from plastic bags. The cleaning mechanism is arranged on the side of the fixed plate and is used to separate the removed residual material from the plastic bag.

[0005] Preferably, the cutting mechanism includes a cylinder and a cutting knife. A base plate connected to the frame is provided below the fixed plate. A through groove for plastic bags to pass through is provided at the bottom of the fixed plate. The cylinder is installed on a support column at the top of the fixed plate. The lower end of the piston rod of the cylinder is provided with a connecting column that is inserted into the through hole on the fixed plate. The cutting knife is provided at the lower end of the connecting column.

[0006] Preferably, the cutting knife is an arc-shaped structure.

[0007] Preferably, the cleaning mechanism includes a cleaning brush and a bolt, and the cleaning brush is a long strip structure and is connected to the fixing block on the side of the fixing plate by a bolt.

[0008] Preferably, four support columns are provided and distributed on the fixing plate in a rectangular array.

[0009] The utility model has the following advantages:

[0010] When the utility model is in use, the piston rod of the cylinder of the cutting mechanism is extended to drive the connecting column and the cutting knife to move downward to cut an arc-shaped notch on the plastic bag, and the residual material adhering to the plastic bag is cleaned down by the cleaning brush, so as to prevent the residual material from being adsorbed on the plastic bag and unable to fall naturally under the condition of static electricity.

DETAILED DESCRIPTION

[0018] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention.

[0019] like Figure 1-6 As shown, the utility model provides a plastic bag residual material cutting device, including a frame 1, a cutting mechanism 3 and a cleaning mechanism 5. The top of the frame 1 is provided with a plurality of support plates 2, and the cutting mechanism 3 is provided with two and is arranged on the fixed plate 4 of the frame 1. The cutting mechanism 3 is used to cut the residual material of the plastic bag. The cleaning mechanism 5 is arranged on the side of the fixed plate 4 and is used to separate the removed residual material from the plastic bag.

[0020] It should be noted that the cutting mechanism 3 includes a cylinder 33 and a cutting knife 36. A bottom plate 31 connected to the frame 1 is provided below the fixed plate 4. A through groove 32 for the plastic bag to pass through is provided at the bottom of the fixed plate 4. The cylinder 33 is installed on the support column 34 on the top of the fixed plate 4. There are four support columns 34 and they are distributed in a rectangular array on the fixed plate 4. The lower end of the piston rod of the cylinder 33 is provided with a connecting column 35 that is inserted into the through hole 37 on the fixed plate 4. The cutting knife 36 is provided at the lower end of the connecting column 35. The cutting knife 36 is an arc-shaped structure.

[0021] In addition, the cleaning mechanism 5 includes a cleaning brush 51 and a bolt 52. The cleaning brush 51 is a long strip structure and is connected to the fixing block 53 on the side of the fixing plate 4 through the bolt 52, so as to facilitate the adjustment of the angle of the cleaning brush 51.

[0022] Specific implementation and principle:

[0023] In actual application, the present invention is wound around the conveyor roller of the frame 1, and the side edges of the plastic bag are located in the through grooves 32 of the bottom plate 31 and the fixed plate 4. The plastic bag is then moved by the pulling device. During the movement of the plastic bag, the piston rod of the control cylinder 33 is extended to drive the connecting column 35 and the cutting knife 36 to move downward. The cutting knife 36 cuts an arc-shaped notch on the plastic bag, and the cleaning brush 51 cleans the remaining material adhering to the plastic bag.
