Color printing film plastic woven barrel material bag composite automatic benchmarking device

Abstract

The invention discloses a color printing film plastic woven barrel material bag composite automatic benchmarking device which comprises a color printing film unwinding frame, a divider, and two or more turning film guiding devices, when color printing films and a plastic woven barrel material bag are compounded, patterns of an A pattern color printing film and a B pattern color printing film are printed on one color printing film in one time by a gravure printing machine, then are divided into two pieces, and each piece of the pattern is turned by the turning film guiding device to reach two sides of a composite pressure roller device, so that when the A pattern color printing film and the B pattern color printing film are compounded with the two sides of the plastic woven barrel materialbag, automatic benchmarking is achieved, and no big effort is needed for benchmarking. The beneficial effects are as follows: benchmarking of the patterns of the color printing films on the two sidesof the plastic woven barrel material bag is accurate, the yield of color printing film plastic woven barrel material bag compounding is greatly improved, the automation degree of a production line isimproved, production efficiency is improved, product quality is improved, heavy manual labor is reduced, and economic benefits of enterprises are improved.

Description

technical field [0001] The invention relates to the field of plastic processing machinery, in particular to a composite automatic marking device for color printing film, plastic braided cylinder material bags. Background technique [0002] At present, the compound device of color printing film and plastic woven cylinder material bag used at home and abroad (see figure 2 ), including a plastic woven cylinder bag unwinding device, A pattern color printing film unwinding device, composite pressure roller device, plastic extrusion double die head, B pattern color printing film unwinding device, color printing film plastic woven bag rewinding device, The double die head includes A die head and B die head. The A cast film is extruded from the A die head, and the B cast film is extruded from the B die head. The tube material bag unwinds through several guide rollers, passes through the middle part of the double die head and enters between the A and B pressure rollers of the compos...

[0002] At present, the compound device of color printing film and plastic woven cylinder material bag used at home and abroad (see figure 2 ), including a plastic woven cylinder bag unwinding device, A pattern color printing film unwinding device, composite pressure roller device, plastic extrusion double die head, B pattern color printing film unwinding device, color printing film plastic woven bag rewinding device, The double die head includes A die head and B die head. The A cast film is extruded from the A die head, and the B cast film is extruded from the B die head. The tube material bag unwinds through several guide rollers, passes through the middle part of the double die head and enters between the A and B pressure rollers of the composite pressure roller device, and the A pattern color printing film is exported from the A pattern color printing film unwinding device into the composite pressure roller. On the side of the A pressure roller in the center of the roller, the B pattern color printing film is exported from the B pattern color printing film unwinding device into the B pressure roller side of the center of the composite pressure roller. In the production state, there are A pressure rollers in turn on the composite pressure roller device and above , A pattern color printing film, A cast film, plastic woven barrel material bag, B cast film, B pattern color printing film, B pressing roller, the cast film has high viscosity and temperature, and the A pattern can be color printed under pressure One side of the film and the plastic woven tube bag is firmly bonded together, and the B pattern color printing film and the other side of the plastic woven tube bag are firmly bonded together. The bag packaging rice, food, etc. is very beautiful and elegant, and is very popular among users. However, because of this production device, the color printing film with pattern A and the color printing film with pattern B are printed and rolled separately, and then unwound from the front and back of the composite pressure roller respectively. Entering, use the artificial eyes to visually align the pattern on the pattern A color printing film and the pattern on the pattern B color printing film on both sides of the plastic woven barrel bag, which not only makes the operator exhausted, but also It is often impossible to align the pattern on the pattern A color printing film with the pattern on the pattern B color printing film. The subsequent bag making process will cause the plastic woven tube bag to have a complete pattern on one side and the pattern on the other side. Incomplete, and some were cut off at the middle, especially in the process of replacing the color printing film roll, resulting in a large amount of waste products
