Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging, in particular to an easy-folding line device. Background Art
[0002] PVC hard sheet is a thermoplastic resin, which is mainly made of vinyl chloride monomer through polymerization reaction and certain additives (such as stabilizers, lubricants, fillers, etc.) are added. This material is usually called rigid polyvinyl chloride (UPVC) or hard PVC. UPVC is a specific category of hard PVC, which refers to hard PVC that does not contain or use plasticizers. PVC hard sheet has high hardness and its transparency is better than polyethylene and polypropylene, but inferior to polystyrene. PVC hard sheet has a wide range of applications, including but not limited to plates, pipes, soles, toys, doors and windows, wire sheaths, stationery, etc.
[0003] The problem of adjusting the easy-folding line of PVC hard sheet packaging materials in filling machines is currently basically solved by adjusting the depth of the easy-folding line by a screw, and the position is fixed after adjustment. Because the position of the easy-folding line blade is fixed and cannot be moved, the packaging material cannot be quickly and accurately transferred to the right position when transferring the packaging material. To solve this problem, a easy-folding line device is designed. Utility Model Content

[0010] Beneficial Effects
[0011] The utility model provides an easy-folding line device. The utility model adjusts the left cylinder, the right cylinder, the middle partition of the easy-folding line, the easy-folding line blade, and the automatic centering bearing are located on the sliding bearing. The PVC hard sheet is guided to the designated position through the middle partition of the easy-folding line. The middle partition of the serial number easy-folding line separates two PVC hard sheets. The left cylinder and the right cylinder are cylinders for opening and closing the mechanism. When the mechanism is working, the left cylinder and the right cylinder are provided with air source by the equipment, and the cylinder rod extends. At this time, the automatic centering bearing fits the PVC hard sheet and the middle partition of the easy-folding line. Because the automatic centering bearings are respectively distributed on both sides of the middle partition of the easy-folding line, it can be ensured that the cylinders on both sides are evenly and centrally distributed with the middle partition of the easy-folding line when they are extended, and it is ensured that the center position of the easy-folding line blade corresponding to the middle partition of the easy-folding line is the same on both sides. The sliding bearing is moved up and down by rotating the adjusting handle through the threaded rod and the sleeve thread linkage, thereby adjusting the height of the equipment, completing the adjustment of the blade position, and accurately moving the packaging material to the use position.
