Technical Field
[0001] The utility model relates to a packaging bag production cutting device, belonging to the technical field of packaging bag production. Background Art
[0002] Packaging bags refer to bags used to package various supplies, which make it convenient to transport and store goods during the production and circulation process. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags are eventually transported to garbage dumps for treatment like general garbage, and only 7% of plastics are recycled.
[0003] A cutting device is required in the production of packaging bags. However, when the existing cutting device is cutting the packaging bags, the material of the packaging bags is relatively soft and cannot be tightened, resulting in uneven cuts, which affects the cutting efficiency and cutting quality.
[0004] Therefore, a packaging bag production cutting device is proposed. Utility Model Content

[0012] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:
[0013] 1. The utility model drives the lower pressure plate to move downward by extending the clamping cylinder, clamps and limits the packaging bag to be cut on the inner side of the U-shaped plate to avoid deviation during the cutting process, and drives the positive and negative threaded rods to rotate through the output end of the servo motor. The positive and negative threaded rods drive the threaded sleeves to move outward through the action of the threads, and the threaded sleeves drive the U-shaped plate to move outward, so that the packaging bag clamped on the inner side of the U-shaped plate extends outward and tightens, avoiding uneven incisions during the cutting process, thereby improving the cutting quality and efficiency.
