Description

Technical Field

[0001] This utility model relates to the field of packaging machinery, specifically a transverse traction conveying device for packaging bags. Background Technology

[0002] In the production of flexible packaging bags using film encapsulation, for various liquids, viscous substances, powders, and granular packaging materials, the process of metering, forming, and sealing does not involve cutting into individual bags. Instead, it forms continuous packaging bags with the sealed edges joined together. (See attached image) Figure 7 This diagram illustrates a three-side seal packaging bag arranged horizontally. After the packaging film is shaped, folded, and filled with material, the two sides of the film are glued together to form a longitudinal seal 302. The horizontal separation of each packaging bag forms a transverse seal 301. The transverse seal 301 and the longitudinal seal 302 together form a single packaging bag. As long as the transverse seal 301 is not cut in the middle, the packaging bag shown in the diagram is formed.

[0003] Currently, continuous packaging bags are widely used in the fast-moving consumer goods (FMCG) industry. These bags, which do not undergo shearing by the packaging machine, are typically used on bag sorting and dispensing machines, generally employing a longitudinal traction conveyor system. However, in this longitudinal traction conveyor system, the traction conveying of continuous packaging bags is unstable due to factors such as the power of the traction drive, the weight of the packaging bags, and machine vibration. While this system is suitable for bag sorting and dispensing machines where stability requirements for traction conveying of continuous packaging bags are not high, it is unsuitable for applications requiring punching or rounded corner cutting, where higher stability is required. Summary of the Invention

[0004] The purpose of this utility model is to address the above-mentioned shortcomings by providing a transverse traction conveying device for packaging bags. This device can solve the problem of unstable conveying caused by the combined effects of the packaging bags' own weight, external vibrations, and transmission force during the longitudinal traction conveying process, which is beneficial to the further operation of subsequent equipment.

This improves the stability of the packaging bags during lateral traction transmission, solves the problem of poor stability caused by longitudinal traction transmission of packaging bags, and facilitates the further operation of packaging equipment such as punching and rounding corner cutting. In summary, this invention can solve the problem of unstable transmission caused by the combined effects of the packaging bags' own weight, external vibration, and transmission force during longitudinal traction transmission, which is beneficial to the further operation of subsequent equipment and is worthy of widespread application.
