Description

Technical Field

[0001] The utility model relates to the technical field of rubber band machines, and particularly refers to a material pulling device of a rubber band machine. Background Art

[0002] In the production of rubber bands, the usual production process is to use bundled or rolled rubber bands as raw materials, cut them into segments and sew them into circles. In this production process, it is usually completed by manual operation or separate operation of multiple single machines with different functions.

[0003] When the rubber band enters the next working station from some working stations, a special moving device, that is, a material pulling device, is required to complete the operation. For example, an automatic rubber band machine disclosed in Chinese Patent CN201920429727.X includes a material pulling device, which is respectively arranged at both ends of a flipping manipulator device with a feeding device. The material pulling device includes a clamping mechanism capable of clamping the rubber band and a sliding mechanism for dragging the clamping mechanism to move. A connecting plate is arranged on the sliding mechanism and connected to the workbench; however, there are still some deficiencies in this patent that the connecting plate is directly fixed to the workbench through fixing parts such as screws. When the material pulling device picks up the fabric on the feeding device, due to the installation error of the connecting plate, the material pulling device tilts, resulting in the tilted rubber band being pulled. When the next process of the rubber band machine flips both ends of the rubber band, the two ends of the rubber band cannot be aligned, and the two ends of the rubber band are misaligned (as Figure 3 shown), resulting in unqualified quality of the sewn rubber band circles. After the rubber band circles are sewn onto clothes, it affects the aesthetics of the clothes. Summary of the Invention
