Zipper discharging device for bag making machine

Abstract

The invention relates to a zipper discharging device for a bag making machine. A side plate is fixed to a bottom plate. One end of a roller shaft is installed on the side plate. A roller is installed on the roller shaft through a third bearing in a supported manner. A blocking step is arranged at one end of the roller. A blocking ring is installed at the other end of the roller. One end of a swing rod is connected to the roller shaft through a second bearing. A first movable guide roller and a second movable guide roller are installed at the other end of the swing rod. One end of a swing arm is fixed to the swing rod, and the other end of the swing arm is connected with the side plate through a tension spring. The rear end of a locking base is hinged to the side plate, a long groove is formed in the front portion of the locking base, and the distance between the center of the long groove and the rotary center of the roller shaft is gradually increased from the back to the front. A brake block is fixedly installed in the middle of the locking base. A small shaft is installed on the swing rod and penetrates the interior of the long groove in the locking base. A fixed rod is fixedly installed on the side plate, and a first fixed guide roller and a second fixed guide roller are installed at the upper end of the fixed rod. Zippers can keep proper tension in the discharging process, the discharging effect is good, working efficiency is improved, and labor intensity is relieved.

Description

technical field [0001] The invention relates to a zipper discharging device, in particular to a zipper discharging device for a bag making machine, belonging to the technical field of bag making machines. Background technique [0002] With the continuous development of the economy, the market's functional requirements for bag making machines are becoming higher and higher, such as more and more packaging bags are required to have a zipper sealing function. Although the bag making machines currently on the market can realize the production of zipper packaging bags, the zipper feeding effect is poor, resulting in low work efficiency and affecting the production efficiency and market competitiveness of enterprises. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a zipper discharge device for bag making machines, which has a compact structure and simple operation, can keep the zipper at a sui...
