[0036] The working principle and usage process of the present utility model: When in use, when it is necessary to cut the garbage bag, first move the garbage bag and place the middle part of the garbage bag on the top of the tension rod 6, and then place the two ends of the garbage bag on the tops of the two placement racks 71 respectively by pulling. Then, start the servo motor 83 through the control panel 16 to drive the lead screw 82 to rotate by the output end of the servo motor 83. The rotation of the lead screw 82 can drive the connecting plate 81 to move downward, and the downward movement of the connecting plate 81 can drive the two pressing plates 72 to move downward, so as to press and position the garbage bag on the top of the placement rack 71. At this time, the garbage bag is in a straightened state. The user then turns on the heating wire 5 through the control panel 16 and starts the cylinder 3, so that the high-temperature heating wire 5 can descend to cut and melt the garbage bag, avoiding the situation of the garbage bag being damaged.

[0037] To sum up: For this cutting device for producing and preparing garbage bags, by setting the tension rod 6, first place the garbage bag to be cut on the top of the tension rod 6, and the surface of the garbage bag can be straightened by pulling the two ends of the garbage bag, so as to avoid the heating wire 5 from contacting other parts of the garbage bag when cutting and melting the garbage bag. This solves the problem that since the device does not have a positioning structure for the garbage bag, after the garbage bag is placed on the top of the support table, due to its own gravity, the garbage bag located on the top of the groove will sink, and some garbage bags have wrinkles on their surfaces. Therefore, when the heating wire descends to cut and melt the garbage bag, it is easy to contact other parts of the garbage bag, which easily causes the garbage bag to have excessive damage and cause excessive losses.
