Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag processing, in particular to an intermittent conveying device for packaging bags. Background Art

[0002] During the production process of packaging bags, it is necessary to punch holes in the packaging bags. When punching holes in the packaging bags, it is necessary to stop the forward conveyance of the packaging bags, and after the punching is completed, the normal packaging bags are conveyed forward normally.

[0003] Patent document CN217169994U discloses a feeding device for a bag making machine, including bottom plates on the left and right sides. A support plate is provided directly above the bottom plates. A rotating plate is arranged between the support plates on the left and right sides. The left and right end faces of the rotating plate are fixedly connected with rotating shafts. A first motor is fixedly installed on the left end face of the left support plate. Grooves are formed on the upper and lower end faces of the rotating plate. An installation groove is formed on the inner right side wall of the groove. A second motor is fixedly installed inside the installation groove. The output end of the second motor is fixedly connected with a threaded rod. Moving blocks are threadedly connected to the left and right sides of the outer surface of the threaded rod. This device rotates the upper and lower material rolls in turn to avoid the situation where bag making cannot be carried out when the material roll needs to be disassembled or replaced. At the same time, the second motor facilitates positioning the new material roll.

[0004] However, the feeding of the raw materials by this feeding device is continuous. When the raw materials in the front stop moving, the feeding device is still in the feeding state, which will cause the raw materials to not be in a taut state, thus affecting the quality of the finished packaging bags. Therefore, it is necessary for us to improve such a structure to overcome the above defects. Summary of the Utility Model

[0032] 1. By providing a swinging assembly, the present utility model realizes the intermittent conveying of the film material. When the film material stops moving forward, the rotating assembly and the supporting assembly continue to work to release the film material. The swinging assembly moves forward to traction the released film material to ensure that the released film material is in a taut state. When the film material needs to move forward, a pulling force is transmitted from the front, and the swinging assembly moves backward. Driven by the pulling force, the film material moves forward normally. This process is repeated to achieve the conveying of the film material. By controlling the stroke of the swinging assembly, the tension of the film material is adjusted, making the control of the tension force of the film material more accurate, increasing the accuracy of subsequent preparation, and thus improving the quality and accuracy of the finished packaging bag.
