The invention belongs to the technical field of feeding objects to machines and particularly discloses a paper feeding device of a die cutting machine. The paper feeding device of the die cutting machine comprises two paper feeding units. Each paper feeding unit comprises suction nozzles, a rigid pipeline, a first paper pushing claw, a second paper pushing claw, a chain and chain wheels. Each rigid pipeline is arranged on one side of the corresponding paper feeding unit. Each suction nozzle is downward and fixed to the corresponding rigid pipeline. An air exhaust device is arranged in each rigid pipeline. The two ends of each rigid pipeline are rotationally connected with rotating sleeves. A cavity communicating with the corresponding rigid pipeline is arranged in each rotating sleeve. A valve element is arranged in each rigid pipeline. One end of each valve element is fixed to one side of the corresponding rigid pipeline. The other end of each valve element is a ball matched with the corresponding rotating sleeve. Each ball is rotationally connected with the corresponding rotating sleeve. An L-shaped channel is formed in each valve element. Each rigid pipeline communicates with the corresponding rotating sleeve through the corresponding L-shaped channel. A first pipeline and a second pipeline are connected to the rotating sleeve. When the paper feeding device of the die cutting machine is adopted to feed paper, paperboards can be smoothly disengaged from the paper pushing claws, and the situation that the paper boards are taken away by the paper pushing claws and deviate from a cutting rail of the die cutting machine is avoided.
Description
technical field [0001] The invention belongs to the technical field of supplying objects to machines, in particular to a paper feeding device for a die-cutting machine. Background technique [0002] At present, the semi-automatic die-cutting machine used in the domestic market adopts the method of manual paper feeding when die-cutting cardboard, that is, the paper is fed through the rising of the rear paper pile, and then the paper that needs to be die-cut is fed one by one by manpower. into the die-cutting machine. This method of paper feeding requires direct human labor. When operating continuously, the operator is in a state of high concentration for a long time, the labor intensity is high, the operator is prone to fatigue, and has a high risk. Injury; At the same time, there are problems such as high die-cutting cost and low paper feeding efficiency. [0003] The Chinese invention patent with the publication number CN103771164A discloses a paper feeding device for a d...
