Description

Technical Field

[0001] The utility model relates to the technical field of plastic woven tubular bag processing equipment, in particular to a plastic woven tubular bag slitting and cutting device. Background Art

[0002] Plastic woven tubular bags are commonly known as woven bags. During processing, plastic strips are woven into continuous tubular bags through a weaving machine, and then sheared to form bags with one end open. In order to facilitate collection, storage and transportation, the current tubular bags will not be cut all at once during shearing. Uniform and continuous fractures with a certain interval will be formed on the tubular bags. Each fracture is not completely cut off, and a thinner connection will be left. When used later, the fracture can be directly torn apart. This method facilitates the winding and use of the tubular bags.

[0003] The slitting machines currently used for tubular bags, namely cam reciprocating cutting machines, will affect the smooth cutting of the tubular bags due to phenomena such as blunt or curled blades. In addition, if the cutting is not smooth, it will also cause unevenness and burrs at the break, which may cause the bag opening to break later, affecting the appearance and quality.

[0007] A further technical solution is: the cutter is located in the middle of the inductor coil.

[0008] A further technical solution is: the scraping mechanism includes a vertical plate, a sliding rod, a tension spring and a scraper, the vertical plate is symmetrically installed on the frame, the sliding rod is slidably installed on the vertical plate through the tension spring, the two scrapers are respectively installed on the two sliding rods, and the two scrapers are pressed against both sides of the cutter.

[0026] When the induction heating device 5 is powered on, the induction coil 4 works on the cutter 2, and the cutter 2 heats up. The temperature is comprehensively considered according to factors such as the sharpness of the cutter 2 and the cutting speed, so as to achieve the effect of semi-melting and semi-cutting the tubular bag. Then, the tubular bag is driven by the existing conveying equipment and passes through the slitting machine 1 at a uniform speed. The slitting machine 1 drives the cutter 2 to move up and down to achieve a uniform cutting effect of the tubular bag. The cut edge of the tubular bag is flat and smooth, and it also plays a role in tidying up the cut to prevent burrs. Even if the cutter is blunt or curled, it will not affect the cutting effect. In addition, the scraping mechanism 6 cleans the cutter 2 that moves up and down, and scrapes off the residue adhering to the cutter 2 on the basis of hot cutting of the tubular bag, cleans the cutter and ensures the quality of the cutting.

The vertical plate 7 is symmetrically mounted on the frame 3. The slide rod 8 is slidably mounted on the vertical plate 7 through the tension spring 9. The two scrapers 10 are respectively mounted on the two slide rods 8, and the two scrapers 10 are pressed against both sides of the cutter 2.

[0030] The cutter 2 moves up and down, pressing against the scraper 10 which moves back and forth in the horizontal direction. Under the action of the tension spring 9, the scraper 10 always presses against both sides of the cutter 2, thereby cleaning the residues on both sides of the cutter 2 more thoroughly.

[0031] Preferably, a limit plate 11 is provided at the outer end of the sliding rod 8 .

[0032] The limiting plate 11 prevents the slide bar 8 from falling off.
