Description

Paper feeding gripper bar device of die cutting machine Technical Field The utility model relates to the technical field of paper feed gripper bars, in particular to a paper feed gripper bar device of a die cutting machine. Background In the technical field of paper feeding teeth-arranging devices of the existing die cutting machines, the outer shaft of the teeth-arranging device is used as a key component of the paper feeding teeth-arranging device, and the paper biting teeth on the outer shaft are easy to wear, damage and the like due to frequent contact with paper and bearing larger friction force, tension and the like in the long-time running process. Once the paper biting teeth are damaged, the paper feeding precision and the die cutting quality of the die cutting machine are directly affected, so that the adverse phenomena of unstable paper conveying, die cutting position deviation and the like are caused, and the production efficiency and the product quality are further reduced. However, the existing paper feed gripper bar device of the die cutting machine has the defects that paper biting teeth on the outer shaft of the gripper bar are inevitably replaced due to abrasion, damage and the like in the actual use process of the paper feed gripper bar device of the die cutting machine. The traditional replacement mode often needs to replace the whole dental row device, so that the maintenance cost is increased, and the resource waste is caused. Therefore, a paper feeding gripper bar device of a die cutting machine is designed to solve the problems. Disclosure of utility model The utility model aims to provide a paper feeding gripper bar device of a die cutting machine, which aims to solve the problems in the background technology. In order to solve the technical problems, the paper feeding gripper bar device of the die cutting machine comprises a gripper bar inner shaft, a gripper bar outer shaft is sleeved on the outer side of the gripper bar inner shaft, the gripper bar outer shaft is in sliding connection with the gripper bar inner shaft, a plurality of paper biting teeth for biting paper are arranged on the gripper bar outer shaft, the gripper bar outer shaft comprises a first outer shaft and a second outer shaft, and a male end and a female end which are arranged side by side are arranged on the end faces of the first outer shaft and the second outer shaft. Further, the male end is a stand column protruding out of the end face of the first outer shaft, and the female end is a sleeve protruding out of the end face of the first outer shaft. Further, a positioning groove is formed in the end face of the first outer shaft around the periphery of the male end, and the inner diameter size of the positioning groove is matched with the outer size of the female end. Further, a clamping strip is arranged on one side of the male end, a clamping groove is formed in the side wall of the female end, and the clamping strip is matched with the clamping groove. Further, the cross section of the male end is of a circular structure, and the cross section of the female end is of a circular ring structure. Further, a driving assembly is arranged on the outer side of the inner shaft of the dental row, and the driving assembly is connected with the outer shaft of the dental row and used for driving the outer shaft of the dental row to slide. Further, the drive assembly comprises a drive motor for providing power and a coupling rod with one end connected with the drive motor and the other end connected with the dental floss outer shaft. Further, the dental row outer shaft is arranged on the dental row inner shaft through a linear bearing. Compared with the prior art, the utility model has the beneficial effects that: 1. According to the utility model, the first outer shaft or the second outer shaft corresponding to the damaged part is disassembled, and then the tail parts of the new first outer shaft and the new second outer shaft are spliced together through the male end and the female end, so that the whole dental row device does not need to be replaced, the maintenance cost is reduced, and the economical efficiency of equipment is improved. 2. According to the utility model, through the connection mode of the male end and the female end, the first outer shaft and the second outer shaft have the characteristic of modularization, and the first outer shaft and the second outer shaft with different specifications and types can be combined through the male end and the female end so as to adapt to the requirements of different die cutting machines.
