Description

Technical Field

[0001] The utility model relates to the technical field of inner mucosa manufacturing, in particular to an inner bonding machine for efficiently bonding an inner lining film cloth base. Background Art

[0002] The preparation process of the inner mucosal plastic woven bag is to bring the double-layer co-extruded lining film (the inner layer of the lining film is generally made of low-density polyethylene, and the outer layer is made of EVA resin) into the woven cloth during the weaving process of the hollow circular loom, inflate it to flatten it, and roll it up to become an inner lining film cloth base. After the inner lining film cloth base is inflated, it is heated and bonded by the heating cylinder of the inner bonding machine, printed by the printing machine, cut by the slitting machine, and sewn to produce the inner mucosal plastic woven bag.

[0003] The liner bag is generally made by blowing a plastic melt into a film through a film blow molding machine. In the prior art, the liner bag needs to be cooled during its processing. The plastic melt often needs to be cooled during the blow molding process so that it can be formed into a film. However, the cooling mechanism in the existing device for preparing and processing the liner bag of a plastic woven bag has a simple structure and low cooling efficiency, and cannot achieve all-round cooling of the plastic melt. In addition, the plastic melt needs to be guided during the process of blow molding into a film to prevent the film from being deformed. However, the prior art device for preparing and processing the liner bag of a plastic woven bag lacks a guiding device, which causes the liner bag to be deformed due to gravity during the production process, thereby reducing the qualified rate of the product.

[0040] Specifically, the hot air blower 311 collects and heats the outside air, and then blows it into the outer cylinder 31, so that the inner sticky cylinder 32 is heated up for internal sticking;

[0041] The adhesive cylinder 32 is provided with a blocking piece 321 surrounding the array;

[0042] Specifically, the baffle 321 is configured as a first baffle and a second baffle, wherein the design range of the first baffle is 30°-40°, and the design range of the second baffle is 20°-40°. In this solution, the first baffle is preferably configured as 35° and the second baffle is 30°.

[0049] The winding mechanism 5 is located at the rear side of the second traction mechanism 4 .
