A three-side sealing machine

Abstract

The invention provides a three-side sealing machine. The three-side sealing machine comprises a rack, a packaging film conveying part, a film pressing and sealing and cutting part, a material conveying platform material pushing structure, a material protecting mechanism and a chain plate line feeding part. Materials can be automatically conveyed, a product drive channel is formed by protecting plates on the two sides, the side portions of driven products are limited, the height direction and the horizontal transverse direction of the protecting plates can be adjusted, and adjusting adaptation can be carried out according to the appearances of the products. Through the design of the material pushing structure and the material protecting mechanism, the products or materials conveyed to the position of a material conveying platform are automatically pushed to the sealing position, manual operation is not needed, the labor cost is reduced, and the processing efficiency of mechanically pushing the materials is improved. The materials are conveyed to the film pressing and sealing and cutting part, the three sides are subjected to film pressing and side sealing and cutting at the same time, the structure is reasonable, material packaging film pressing and sealing and cutting are achieved through one step, and the good effects of improving the sealing and cutting efficiency and reducing the reject ratio are achieved.

Description

technical field [0001] The invention relates to the technical field of packaging machinery, in particular to a three-side sealing machine. Background technique [0002] With the development of society and the improvement of people's living standards, the degree of diversification of products is getting higher and higher, and the requirements for product packaging are also increasing one after another. After the product is produced, an important process needs to be carried out-packaging and sealing. Packaging machinery has largely replaced traditional manual operations, greatly reducing work intensity, while packaging products are beautiful and the authenticity rate is high. Packaging machinery has been widely used in all walks of life for its high efficiency, easy operation and easy maintenance. During the use of packaging machinery in various industries in China, the degree of automation of the machines varies, while the degree of standardization, generalization and seria...

Problems solved by technology

During the use of packaging machinery in various domestic industries, the degree of automation of the machines varies, and the degree of standardization, generalization, and serialization is not high. There are repeated designs, unreasonable allocation of resources, and waste in the entire industry.

The sealing machine currently used is just a simple sealing operation. It is a plastic bag that is formed manually, and then one side is sealed. The products that need to be sealed need to be manually transported to the sealing place, and then manually taken out after being sealed by the sealing machine. , it is impossible to realize fully automated pushing of raw material products, high labor costs, and low operating efficiency; in the process of pushing materials to the sealing place, the materials are prone to deviation and detachment from the platform, which not only causes waste of materials, but also causes improper edge sealing. Qualified, inconvenient to clean, low efficiency of sealing operation, requiring worker care; moreover, the existing sealing machine has an imperfect structure for sealing and cutting materials, and the pressing and sealing and cutting of material packaging need to be carried out step by step. The problem of low sealing and cutting efficiency and high failure rate; the current sealing machine does not have a mechanism for mechanized delivery of materials to the sealing and cutting machine, and most of them use manual materials to be placed on the sealing and cutting machine. The conveyor belt continuously pushes the materials to the sealing and cutting machine in a straight line, and the amount of materials pushed is not easy to control, resulting in the problem of poor consistency in the size of the sealed and cut packages
