Problems solved by technology

Now the inner bag suit is mainly operated by workers manually, with the help of simple mechanical devices, and the process of the inner bag suit is completed manually: align the inner and outer bag openings → fold the inner and outer bag openings inward → thermally bond and fold Good inner and outer pockets, the manual fitting process is cumbersome, the work efficiency is low, and the labor cost is high
However, the existing thermal bonding equipment for the inner and outer bags of woven bags is too low in automation and cannot solve the above problems well.

Abstract

The invention relates to an inner and outer bag automatic thermal bonding device. The device comprises a main frame body, an opening mechanism, a stretching mechanism and an edge folding thermal bonding mechanism, wherein the opening mechanism is arranged at the end of the main frame body, a movable frame body capable of sliding front and back is arranged in the main frame body, and the stretchingmechanism and the edge folding thermal bonding mechanism are installed on the movable frame body; the opening mechanism comprises a tray and a suction cup moving up and down, the stretching mechanismcomprises supporting plates A which are arranged in a bilateral symmetry mode and supporting plates B which are arranged in an up-down symmetry mode, the supporting plates A and the supporting platesB are connected with a front-back moving mechanism, the front-back moving mechanism is installed on the movable frame body, and a pressing plate is arranged on the main frame body on the outer sidesof the supporting plates A; and the edge folding thermal bonding mechanism comprises an edge folding pressing plate, a thermal bonding floating pressing plate and a thermal bonding welding head whichare arranged in the circumferential direction, the edge folding pressing plate is located on the inner side of the thermal bonding floating pressing plate, and the edge folding pressing plate, the thermal bonding floating pressing plate and the thermal bonding welding head move towards the center. The device is simple in operation, stable in operation, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of plastic woven bags, in particular to an automatic thermal bonding device for inner and outer bags. Background technique [0002] In the field of plastic woven bag packaging, according to the technical requirements of the packaged items, it is necessary to set a plastic inner bag in the woven bag, and the specific process requirements for the inner bag: 1. The bag needs to have a certain loose margin in the outer bag, so the inner bag before gluing is about 5cm longer than the outer bag mouth; 2. First align the inner and outer mouths, and then fold the inner and outer bag mouths inward by 3cm Left and right, and then thermally bond the inner and outer bags together at the folded mouth of the bag by using a hot tool. Now the inner bag suit is mainly operated by workers manually, with the help of simple mechanical devices, and the process of the inner bag suit is completed manually: align the inner and out...
