[0009] The upper folding part of the packaging bag is located between the gusset plate and the guide plate. Every time the machine is running, the bag-carrying cylinder is retracted and the part of the packaging bag that is higher than the guide plate is turned over. The bag-inserting cylinder is extended to insert the bag onto the guide plate. The guide plate has reverse barbs on its upper side to fix the folding part of the packaging bag. The packaging bag is then sent to the sealing machine through the folding bag feeding cylinder for sealing, thereby realizing the folding function. After the action is completed, the folding bag feeding cylinder is retracted, the bag-inserting cylinder is retracted, and the bag-carrying cylinder is extended to complete a folding action cycle.

[0010] Beneficial effects:

[0011] 1. The present invention is a cylinder folding machine, which solves the problem that the folding effect of existing packaging bags is not ideal due to the different hardness of the packaging bags during the packaging process. The pneumatic folding machine mechanism can fold the packaging bags at high speed and stably, and has the advantages of ensuring the consistency of the folding of the packaging bags, fast folding speed, no distinction between soft and hard bags, and good adaptability.

[0012] The present invention adopts a combination of three cylinders, namely, a bag inserting cylinder, a bag carrying cylinder and a bag folding and feeding cylinder, to complete movements in three directions of X, Y and Z, which greatly improves the folding quality of the packaging bag. In addition, the cylinders are simple and convenient to use and operate, and run smoothly, which improves the operator's work efficiency while ensuring quality.

[0013] The mounting body, buckle plate and lead-in plate of the present invention are cut by a laser cutting machine and then assembled by welding, which can make the size precise and effectively improve the process performance of the product. At the same time, a group of reinforcing ribs are welded above the mounting body to improve the rigidity of the mounting body and ensure the smooth operation of the product.

[0014] The mounting body and the buckle plate of the present invention are both provided with long holes, so that the bolts in the long holes can be adjusted as needed, which is convenient and practical.

[0015] The polytetrafluoroethylene plate of the invention is processed by a milling machine, so that it has precise size and good surface finish. At the same time, the material has the dual advantages of excellent wear resistance and non-adhesion, which can make the contact part of the folding bag pass smoothly and ensure the folding quality.
