Description

Technical Field

[0001] This utility model relates to the field of packaging bag processing, and in particular to a cutting device for packaging bag processing. Background Technology

[0002] A search of Chinese patents revealed publication number CN221090130U, which discloses a cutting device for processing plastic packaging bags. This device relates to the field of plastic packaging bag processing technology and includes a cutting platform, a column, conveyor rollers, and a tensioning cutting assembly. The tensioning cutting assembly is positioned between the column and the conveyor rollers and is used to stretch the plastic film and cut it at equal intervals. The tensioning cutting assembly includes a motor, a transmission wheel, a transmission belt, a slot, a compression spring, a blade, and a friction sleeve. In this invention, the plastic film conveyed between the leftmost set of conveyor rollers and the middle set of conveyor rollers is tensioned. Simultaneously, when passing the rightmost set of conveyor rollers, the elasticity of the compression spring and the blade are used to cut the plastic film. Therefore, by using a motor as the driving force to tension and cut the plastic film at equal intervals during the plastic packaging bag processing, manufacturing costs are greatly reduced and operational difficulty is lowered.

[0003] Existing cutting devices are inconvenient for material replacement. Packaging bag materials are typically fed onto a feeding rod, which needs to be replaced after use. Replacement requires disassembling the feeding rod, which is usually bolted on. Disassembly and reassembly require tools, making the process cumbersome, increasing workload, and reducing replacement efficiency. Furthermore, they lack anti-deviation functionality. During cutting, plastic bags are typically conveyed to the cutting station via guide rollers. During this conveying process, the plastic bags are prone to deviation, causing slanted cuts and affecting cutting quality, making them unsuitable for use. To address these problems, we propose a cutting device for packaging bag processing. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for packaging bag processing, which has the advantages of easy material changing and anti-deviation function.

[0044] Brief description of the usage process: Load the plastic bag material onto the feeding rod, then place one end of the plastic bag material between the positioning plates 20, and then pass it through the conveying roller 27 to place the plastic bag on the cutting seat 25. The cylinder 22 drives the lifting plate 23 to lower the cutting blade 24 and the pressure plate 30. Since the pressure plate 30 is located at the bottom of the cutting blade 24, the lowering of the lifting plate 23 first presses the plastic bag tightly, and then the cutting blade 24 cuts the plastic bag to achieve the cutting purpose. When changing materials, press the pressing head 34. The pressing head 34 moves, which drives the pressing rod 8 to move. The moving pressing rod 8 drives the locking connector 10 to move, so that the locking connector 10 is disengaged from the fixing hole 11. Rotate the fixing cylinder 6 to rotate the notch 7 to the top and make it coincide with the fixing groove 4. Remove the feeding rod 5 to replace the material. After replacement, put both ends of the feeding rod 5 into the fixing groove 4, and then... Rotate the fixed cylinder 6 to rotate the notch 7 to the bottom. The fixed cylinder 6 fixes both ends of the feeding rod 5 in the fixed groove 4. Release the pressing head 34. The pressing rod 8, under the action of the first spring 9, drives the snap-fit ​​connector 10 to engage with the fixing hole 11, thus fixing it and completing the replacement, thereby facilitating material replacement. Set up the positioning plate 20. The positioning plate 20 restricts the plastic bag between the positioning plates 20 to prevent the plastic bag from shifting. By rotating the rotating head 33, the rotating head 33 drives the bidirectional lead screw 18 to rotate. The bidirectional lead screw 18 drives the sliding block 17 to move. The sliding block 17 drives the transmission block 19 to move. The transmission block 19 drives the positioning plates 20 to move relative to or away from each other, moving the positioning plates 20 to the required position. The distance between the positioning plates 20 can be adjusted to accommodate plastic knives of different widths, thereby achieving the purpose of preventing shifting.
