Description

Conveying device of bag making machine Technical Field The utility model relates to the technical field of bag making machines, in particular to a conveying device of a bag making machine. Background The bag making machine is one kind of plastic bag making equipment and its operation principle is to cut, heat and seal plastic film in certain width and length. Additional procedures such as printing, vent hole making and the like can be performed during bag making. The working process of the bag making machine mainly comprises five steps of unreeling, printing, cutting off, sealing and reeling, and automatic operation is needed to be realized through program control. At present, the present disclosure with publication number CN211808155U discloses a hot bag cutting device of a bag making machine, comprising a bag making machine body, wherein a concave frame is fixed on the upper end face of the bag making machine, a sealing device, a cooling device and a cutting device are arranged in the concave frame, the sealing device comprises a first blade, a first supporting plate is fixed on the side wall of the concave frame, a heating pipe is fixed in the first blade, a first cylinder fixedly matched with the first blade is fixed on the upper end face of the bag making machine body, sliding grooves are symmetrically arranged on the lower end face of the first supporting plate, a communicating moving groove is arranged between the sliding grooves, a sliding-matched moving block is arranged in the moving groove, a threaded rod first threaded with the moving block is arranged in the moving groove, and a first motor is fixed on the upper end face of the first supporting plate. In the above scheme, although the prior art can better seal the plastic bag by cutting the seam, the plastic bag after the seam is sealed is required to be rolled later, and when the plastic bag is cut and sealed by the existing hot cutting device, the precision of the hot cutting position and the quality of the hot cutting position can be guaranteed only by stopping conveying the plastic bag, and the rolling device usually runs without stopping, so that the plastic bag is easy to be stretched, further the plastic bag is pulled out, in order to prevent the plastic bag from being pulled out, the rolling device is stopped in the process of sealing the plastic bag by cutting the seam in the prior art, so that the plastic bag is sealed by cutting the seam, but repeated stopping and starting are required, so that a large amount of electric energy is consumed, and the problem of low bag manufacturing efficiency is caused. Disclosure of utility model The utility model aims to overcome the defects of the prior art, and provides a conveying device of a bag making machine, which is provided with an adjusting mechanism, so that the tension of a plastic bag is maintained in a required interval, the problem that a winding device is required to be stopped when a joint of the plastic bag is sealed in the prior art is solved, the consumption of electric energy is saved, and the bag making efficiency is improved. The scheme for solving the technical problems is as follows: The utility model provides a bag making machine conveyor, includes the frame, rotates on the lateral wall of frame to be connected with many conveying rollers, and the upper end of frame is equipped with hot cutting device, and hot cutting device's lower extreme symmetry is fixed with two connecting rods, and the lower extreme of connecting rod is fixed with the connecting plate, and hot cutting device's left side is equipped with stops the subassembly, and hot cutting device's right side is equipped with adjustment mechanism, and adjustment mechanism includes adjustment component and fixed subassembly, is equipped with lifting unit in the frame. When the plastic bag is required to be sealed by lancing, the stop and stop assembly is stopped, so that the plastic bag required to be sealed by lancing is stopped to be conveyed, the lifting assembly is started to drive the hot cutting device to move downwards, the plastic bag is sealed by lancing through the hot cutting device, the winding device is not required to be stopped by arranging the adjusting assembly, when the plastic bag is stopped to be conveyed, the winding device is not required to be stopped, so that the adjusting assembly is driven to move upwards under the action of the plastic bag, when guaranteeing that the plastic bag stops carrying, the plastic bag that needs the rolling can not appear tightening to can not cause the plastic bag rolling to be torn when carrying, when the plastic bag is not stopped carrying, under the action of adjusting part's gravity, make the plastic bag rate of tension that needs the rolling maintain in required interval, thereby prevent that coiling mechanism can not effectively tighten up the plastic bag, simultaneously through being equipped with fixed subassembly, thereby can be fixed to adjusting part ce
