A packaging bag clamping bracket on the injection gun head on a foaming machine

Abstract

The invention discloses a packaging bag clamping bracket on an injection gun head of a foaming machine. The packaging bag clamping bracket comprises a rectangular frame body. The middle of the rectangular frame body is provided with two connecting rods, and both ends of each connecting rod are formed on the inner wall of the frame body. A vertical sleeve seat is formed in the middles of the connecting rods, and the upper end of the sleeve seat is screwed with a plurality of locking screws. A tension rod abuts against the outer walls of two opposite sides of the frame body respectively and absorbs a permanent magnet iron block fixed on the connecting rods and the inner walls of the frame body. Push rods are inserted into the frame body on both sides of the connecting rods, one end of each push rod penetrates the frame body to be fixed at two ends of the corresponding tension rod, and a rectangular connecting block is formed at the other end of each push rod. A vertical pillar is fixed on each connecting block, and a roller is hinged to the top end of each pillar. The bracket can reduce the potential safety hazard in the process of injecting a foaming agent into a small packaging bagby the foaming machine.

Description

Technical field: [0001] The invention relates to the technical field of plastic machinery, in particular to a packaging bag clamping bracket on an injection gun head on a foaming machine. Background technique: [0002] Foaming machine is a kind of plastic machinery, specifically plastic molding machinery. At present, some manufacturers use the head of the foaming machine to inject the foaming agent into the small packaging bag, and then the foaming agent expands to realize the expansion of the small packaging bag. The expanded small packaging bag can be used as a filling in the extra space after the product is packed. It can be used as food, and its inflated small packaging bag is soft, which can protect the product. However, at present, the foaming agent in the small packaging bag is generally used purely by hand, which is not only inefficient, but also has a high temperature after injection, and it is easy to splash on the hands, sticking to the hands and causing injury t...

Problems solved by technology

However, at present, the foaming agent in the small packaging bag is generally used purely by hand. Not only is the efficiency low, but the foaming agent just injected has a high temperature, and it is easy to splash on the hands and cause harm to the employees if it sticks to the hands.
