Punching machine capable of punching continuous conveying materials

Abstract

The invention relates to a punching machine, and specifically relates to a punching machine capable of punching continuous conveying materials. The punching machine comprises a frame, a conveyer device for continuously conveying materials, a detecting device and a punching device and is characterized in that the punching device is provided with an air cylinder, wherein the detecting device is electrically connected with the air cylinder; the extensible piston rod of the air cylinder is connected with a punch head; the bottom surface of the punch head is arc-shaped; a tool holder is arranged below the punch head; the detecting device comprises a photoelectric detector and a coder; the air cylinder is operated by the signal given by the photoelectric detector or the coder. The punching machine designed in the invention uses the high-speed action of the air cylinder, and thus has less possibility of catching the punch head with the arc-shaped bottom surface, so that the materials can be directly punched without being stopped.

Description

technical field [0001] The invention relates to a punching machine, in particular to a punching machine capable of punching continuously running materials. The punching machine can be adapted to bag making machines, film blowing machines, printing machines and other mechanical field. Background technique [0002] Bags are indispensable items in people's daily life. In daily life, people are accustomed to packaging various foods in bags for convenient storage and transportation; as people's awareness of food packaging increases, they gradually have requirements for the freshness and humidity of the food in the packaging bags. Therefore, some packaging bags must have ventilation holes to keep the food fresh; the other is a packaging bag with liquid in the bag, which must have the function of being able to stand, so it also needs to be punched. [0003] Taking the bag making machine as an example, the punching machine on the existing bag making machine has the following disad...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the bag making machine makes bags at high speed, when making bags with air holes or other holes, the bag feeding mechanism must first stop feeding the bags before punching holes on the bag body; if If the bag feeding is not stopped, the punching needle will catch the bag and tear the bag, which seriously affects the bag making speed

[0005] 2. The existing punching method is that the punching needle directly faces the female seat. When the punching machine runs for a long time, the punching needle will wear out, resulting in the punching not being able to be punched out.

Due to the high precision requirements for the cooperation between the punch pin and the female seat, it is not easy to repair and the production cost is expensive
