Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly relates to a horizontal automatic bag-making four-side sealing packaging machine and a packaging method thereof. Background Art

[0002] A packaging machine is a type of machine that packages products, playing the roles of protection and beautification. Packaging machines are mainly divided into two aspects: 1. Assembly line type integrated production packaging, 2. Product peripheral packaging equipment. A horizontal packaging machine is a type of packaging machine applicable to the packaging of various regular objects such as biscuits, rice crackers, snow cakes, egg yolk pies, chocolates, bread, instant noodles, mooncakes, medicines, daily necessities, industrial parts, paper boxes or trays.

[0003] In the prior art, in the existing horizontal packaging machine, the way the packaging bag feeds the paper during the packaging process is in a linear form above, and then materials are placed into the bag. This packaging method will cause the surface of the packaging bag to be uneven after packaging or the packaging bag to deform during heat sealing. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a horizontal automatic bag-making four-side sealing packaging machine and a packaging method thereof to solve the above technical problems.

[0005] The technical solution of the present invention is realized as follows: A horizontal automatic bag-making four-side sealing packaging machine includes a machine body. On the machine body, there are successively arranged a paper feeding station, a material feeding station, a film feeding station, a heat sealing station, a punching station, and a cutting station according to the working sequence. The paper feeding station conveys the paper from the upper end of the machine body to the lower end of the machine body, and rises and enters the heat sealing station before the heat sealing station. The film feeding station is used to send the film into the heat sealing station to realize the up-and-down corresponding cooperation of the paper and the film. An opening is formed at the connection of the paper and the film for the materials in the material feeding station to be sent onto the paper surface of the heat sealing station. The heat sealing station is used to seal the paper and the film in a U shape to form a packaging bag strip. The punching station is used to punch the side edges of the packaging bag strip. The cutting station is used to cut the packaging bag strip.

[0006] By adopting the above technical solution, the conveying mode of the paper is changed to downward conveying, and then upward conveying to before the heat sealing station. The film is also pulled towards the heat sealing station. The positions of the film and the paper correspond up and down, with the paper located below the film. When the equipment operates, the material feeding station pushes the materials onto the paper. The heat sealing station heat-seals the paper and the film. At this time, a bag strip with three parts sealed is formed. After the bag strip advances, the above heat sealing process is repeated to completely seal the bag strip. The completely sealed bag strip enters the punching station for punching, and finally enters the cutting station for cutting into finished products. This structure can prevent the uneven sealing of the paper and the film, reduce the deformation degree of the bag, improve the yield rate, and the feeding accuracy is higher.

[0008] By adopting the above technical solution, the storage mechanism rotates intermittently. When the storage mechanism completes its rotation, the pushing mechanism pushes the material in the storage mechanism into the heat sealing station.

The first synchronous pulley and the second synchronous pulley have the same structure and are connected through a leather toothed belt transmission. A third through groove is opened on the end face of the machine body, and the upper end of the swing rod passes through the third through groove and is hinged to the pushing mechanism. The middle part of the third transmission shaft is keyed to the first transmission sprocket, and a fourth transmission shaft protruding from the rotator is provided on the rotator, and the fourth transmission shaft is keyed to the second transmission sprocket chain-driven by the first transmission sprocket.

[0020] By adopting the above technical solution, the adjustment disc is driven by the third transmission shaft and the synchronous pulley on the disc mounting plate, and the transmission ratio is constant and accurate, so that the pushing mechanism can cooperate with the storage mechanism more accurately. The third transmission shaft drives the feeding station and the storage mechanism at the same time through the synchronous pulley and the transmission sprocket, which further improves the coordination accuracy of the two mechanisms and can effectively improve the product yield.
