Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag processing, in particular to a cutting device for woven bag processing. Background Art

[0002] Woven bags are a common and practical packaging bag. They are usually woven from plastic flat wires, mostly made of polypropylene or polyethylene. Woven bags have the advantages of high strength, low cost, and large capacity, and can meet the packaging needs of a variety of items. The production process is relatively simple and can be mass-produced. In appearance, woven bags have certain pores, which makes them breathable, but relatively weak in moisture resistance. Woven bags are widely used in industrial and agricultural production, such as packaging fertilizers, cement, grain, feed, etc.; in daily life, they are also often used to store clothes, bedding, etc.; when processing woven bags, cutting devices are often used to cut the woven bags to ensure that the specifications of the woven bags during production are within the design indicators.

[0003] Prior art includes a utility model with publication number CN219667611U, which discloses a cutting device for processing packaging bags. The patent adopts a workbench, a cutting mechanism and a cleaning mechanism. A positioning groove is provided on the surface of the workbench. The cleaning mechanism includes two supporting plates fixedly connected to the lower surface of the workbench. Limit rods and lead screws are respectively provided on the surfaces of the supporting plates. A cleaning assembly is jointly provided on the outer surfaces of the limit rod and the lead screw. A servo motor for driving the lead screw to rotate is provided on the side of the supporting plate. A card slot is provided on the side of the supporting plate. A collection box is fixed to the inner wall of the card slot. By setting a tension spring and a movable column, the tension of the tension spring can be used to make the first cleaning block and the second cleaning block fit tightly together, which can increase the friction between the V-shaped notch and the blade, thereby improving the cleaning effect of the blade. In addition, this setting can adjust the size of the V-shaped notch within a certain range, effectively avoiding the situation where the first cleaning block and the second cleaning block are worn out, resulting in the cleaning assembly being difficult to fit the blade. This solves the problem that in the existing equipment, when the wiper is worn out during long-term use by using a screw rod to drive the wiper to move quickly to clean the blade, the wiper block is difficult to contact closely with the blade, thereby greatly reducing the cleaning effect of the wiper block.

[0004] In the process of cutting the rice woven bags with the help of the cutting device, there is an existing woven bag cutting device such as the above-mentioned one. In order to ensure the stability of the woven bags during processing, a negative pressure mechanism is used to limit the position of the woven bags in the processing area of ​​the equipment. Since the rice woven bags are usually woven bags, when the equipment uses a negative pressure structure to limit the position of the woven bags, due to the strong air permeability of the woven bags, the suction force generated by the negative pressure equipment is difficult to stably adsorb the woven bags in the processing area, resulting in a certain degree of deflection of the woven bags when the equipment is processing the woven bags, which then causes deviations in the cutting position, resulting in the problem of scrapping the woven bags.
