A waste removal device for an unwinding die-cutting machine

Abstract

The invention relates to a waste removal device of an unwinding type die-cutting machine. The waste removal device comprises a waste half-removal mechanism, a waste full-removal mechanism and a paperand scrap edge drive mechanism. The waste half-removal mechanism comprises an upper waste half-removal die plate and a lower waste half-removal die plate; the upper waste half-removal die plate is connected with a waste half-removal cam drive unit and moves up and down; the lower waste half-removal die plate is stationary; and a scrap edge collection unit is arranged on the lower portion of the waste half-removal mechanism. The waste full-removal mechanism comprises an upper waste full-removal die plate and a lower waste full-removal die plate; the upper waste full-removal die plate is connected with a waste full-removal cam drive unit and moves up and down; the lower waste full-removal die plate is stationary; and an automatic stacking and lifting unit for collecting finished products isarranged on the lower portion of the waste full-removal mechanism. The paper and scrap edge drive mechanism comprises a drive roller and a plurality of driven rollers, and the drive roller and the driven rollers are used for clamping the products therebetween. By means of the waste removal device, scrap edges, generated after die-cutting, of the products can be effectively removed, the manual waste removal operation is omitted, the number of production and processing procedures is reduced, product transfer is accelerated, the products are fully stripped off and automatically stacked, the production efficiency is high, and the waste removal device shows the energy-saving, cost-saving and environment-friendly concepts.

Description

technical field [0001] The invention relates to the technical field of die-cutting machines, in particular to a waste removal device for an unwinding type die-cutting machine. Background technique [0002] After the traditional die-cutting machine die-cuts the semi-finished products, it is necessary to manually clean up the waste edges on the products to ensure that the products can be separated independently, so that the box-gluing process can be produced efficiently and cleanly, but this requires a lot of labor and increases the manufacturing cost. cost, and it is difficult to achieve lean production. [0003] An improved unwinding die-cutting machine, when the die table presses and cuts the product, the paper is cut into single sheets at the same time, and then the surrounding waste paper is peeled off by the pressure roller with a waste removal needle, and then the Manually collect and stack the semi-finished products at the material device.

[0002] After the traditional die-cutting machine die-cuts the semi-finished products, it is necessary to manually clean up the waste edges on the products to ensure that the products can be separated independently, so that the box-gluing process can be produced efficiently and cleanly, but this requires a lot of labor and increases the manufacturing cost. cost, and it is difficult to achieve lean production

[0003] An improved unwinding die-cutting machine, when the die table presses and cuts the product, the paper is cut into single sheets at the same time, and then the surrounding waste paper is peeled off by the pressure roller with a waste removal needle, and then the Manually collect and stack the semi-finished products at the material device. This method solves the peeling off of part of the waste edge of the product. However, because the products are joined together, the small holes and small pieces of paper between the products cannot be separated from each other because of the needle-shaped waste removal stick. Precise positioning of the single-sheet product after the sheet is broken, still cannot effectively clean up these small pieces of paper, so that the site is full of small garbage, caught in the product, affecting the efficient production of the box-gluing process

[0004] After the roll paper has been die-cut, the connection between each product and between the product and the waste edge basically exists as a needle-like connection point. This is to ensure that the waste edge or product can be removed from the paper at the stripping station. It is easy to peel off, which also brings great challenges to the conveying and precise positioning of the paper in the equipment, because the paper can be advanced by the tension control of the front and rear drive rollers, and the paper must stop when the die-cutting is performed. As the speed increases, the paper The start and stop of the machine becomes frequent, the acceleration is very large, the tension change between the paper becomes extremely serious, and the product is easy to fall apart during the transmission process
