[0002] The reciprocating motion linkage structure for tying bags in a bag-making machine is a support device that enables the needle to reciprocate up and down to tie the bag. A bag-making machine is a machine that produces various plastic packaging bags or other packaging bags. Its processing range includes packaging bags of various sizes, thicknesses and specifications of plastic or other materials. Generally speaking, plastic packaging bags are the main products. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of the reciprocating motion linkage structure for tying bags in bag-making machines.

[0003] The existing linkage structure for bag tying in bag making machines has certain drawbacks. Since it lacks bearings, the contact between the shaft and bearing can generate heat through friction after prolonged use, easily leading to jamming and reducing the machine's operating speed. This negatively impacts the actual usage. Therefore, we propose a reciprocating linkage structure for bag tying in bag making machines. Utility Model Content
