[0002] Plastic bags are bags made of plastic as the main raw material. They are indispensable items in people's daily lives. Due to the increasing demand for plastic bags, the production of plastic bags is also increasing. In the production process of plastic bags, cutting equipment is usually required to cut the plastic bags.

[0003] However, the existing cutting equipment has its cutter and knife holder fixed by bolts. When replacing, multiple extrusion bolts need to be removed one by one before the cutter can be removed and replaced, which increases the difficulty of subsequent replacement. In view of the above reasons, the present application proposes a plastic bag cutting and output device with a quick cutter replacement function. Utility Model Content

When the limit plate fits with the top inner wall of the positioning frame, the pressure plate cannot continue to move up, thereby realizing the positioning of the plastic bag and the cutting knife realizing the cutting of the plastic bag. During the processing, the staff can avoid frequently cutting the positioning of the plastic bag, which can not only reduce the workload but also improve the processing efficiency of the equipment.

[0016] In summary, the utility model has a compact structure and has the function of quickly replacing the cutter, which can reduce the difficulty of subsequent replacement of the cutter. During cutting, the staff does not need to frequently position the cut plastic bags, which not only reduces the workload but also improves the processing efficiency of the equipment.

The limiting grooves and the limiting blocks are movably connected, and the coordinated use of the limiting grooves and the limiting blocks can realize the limitation of the insert block 702 to prevent the insert block 702 from being separated from the mounting seat 701 when being pulled. A cross plate 704 is fixed on the front of the insert block 702, and two plug rods 705 are fixed on the back of the cross plate 704. The plug rods 705 are adapted to the socket 5, and a pull rod 706 is movably provided on the top inner wall of the mounting seat 701, and the bottom of the pull rod 706 is fixed A clamping block 707 is provided, and a slope is provided on the adjacent side of the clamping block 707 and the clamping block 703, and the two slopes are parallel. The top of the plug block 702 is fixedly provided with the clamping block 703, and the pull rod 706 is sleeved with a spring 1, one end of the spring 1 is in contact with the clamping block 707, and the other end of the spring 1 is in contact with the top inner wall of the mounting seat 701, and two limiting rods 708 are fixedly provided on the top of the clamping block 707, and the two limiting rods 708 penetrate the top inner wall of the mounting seat 701 and extend to the outside of the mounting seat 701, and the limiting rods 708 are movably connected to the top inner wall of the mounting seat 701, and a circular hole is provided on the top inner wall of the mounting seat 701, and a sealing ring is provided on the inner wall of the circular hole, and the inner wall of the sealing ring is in contact with the limiting rod 708.
