Material packaging method of prefabricated bag packaging machine

Abstract

A material packaging method for a prefabricated bag packaging machine comprises the following steps: material clamping or holding, prefabricated bag expansion, material pushing, and prefabricated bag removal. In the material clamping or holding process, a material is clamped or held under the action of a clamping mechanism (4) or a holding mechanism (9), and is conveyed to a to-be-pushed station; in the prefabricated bag expansion process; the left and right sides of the bag mouth of the prefabricated bag are expanded under the action of a bag expanding mechanism (5); in the material pushing process, the material moves under the action of a material pushing mechanism (2) in the direction of the bag mouth of the prefabricated bag to the bottom of the prefabricated bag, and continues to be pushed along with the prefabricated bag; and in the prefabricated bag removal process, after moving to the bottom of the prefabricated bag, the material continues to be pushed by the material pushing mechanism (2), and then is removed from the bag expanding mechanism (5). In the whole packaging process, the material can be continuously pushed by a material pushing head into the prefabricated bag, the continuous degree of material conveying and pushing is high, the travel distance of material conveying and packaging is short, and the packaging efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of material packaging, in particular to a material packaging method for a prefabricated bag packaging machine. Background technique [0002] The packaging machine replaces the traditional manual packaging and has the characteristics of fast speed and neat and beautiful packaging. The packaging materials of the packaging machine can be candies, biscuits, paper towels, etc. Among them, the paper towel packaging machine is mainly used for the bagging and packaging of various specifications of soft paper towels. The paper towel packaging machines can be divided into: roll paper packaging machines, paper towel packaging machines, three-dimensional paper towel packaging machines, and wallet paper towels. Packaging machines, etc. Paper pumping packaging machines can be divided into three types: reciprocating packaging machines, three-dimensional packaging machines, and rotary packaging machines.

Problems solved by technology

[0015] The present invention aims to overcome the complex process at a single station of the prefabricated bag packaging machine in the prior art, the many packaging actions, the long travel between each station, the large area occupied by the equipment, the irregular materials that are easy to dump, and the prefabricated bags that are easy to break. Bags, long pushing stroke, poor packaging effect, low packaging efficiency, etc., provide a material packaging method for prefabricated bag packaging machine, the prefabricated bag packaging machine of the present invention can be applied to small packaging machines, medium packaging machines, large packaging machines, etc. Packaging machinery for bag packaging. At the same time, the invention is also suitable for packaging materials such as soft tissue paper, flat roll paper, toilet paper, block food, medicine, roll paper, and bulk food; during the entire packaging process of the invention, the material can be The material is continuously pushed into the prefabricated bag by the pushing head, and the degree of continuous material conveying and pushing is high. Compared with the packaging method of the prior art, the material conveying and packaging journey is shorter and the packaging efficiency is higher.
