Mechanical sheet perforating machine

Abstract

The invention discloses a mechanical sheet perforating machine. Wallboards (8) are respectively arranged at both sides of a supporting frame (13); moving wallboards (9) are arranged on the wallboards (8); two perforating needle rollers (1) are arranged between the wallboards (8) from top to bottom; perforating wheels (14) are arranged at intervals on the perforating needle rollers (1); two rubber carrier rollers (2) are arranged between the moving wallboards (9); the horizontal positions of the rubber carrier rollers (2) are respectively opposite to the perforating needle rollers (1); a driving roller (3), a guide roller (4), a limiting roller (5) and a tensioning roller (6) are arranged between the wallboards (8); a group of belts (7) is wound among the driving roller (3), the guide roller (4), the limiting roller (5) and the tensioning roller (6); and all the components are integrated into the mechanical sheet perforating machine. According to the perforating machine disclosed by the invention, a sheet passes through between the two groups of staggered perforating needle rollers; the sheet which has low tensile strength, is easy to break and is softer is subjected to seamless butting continuous perforation; materials are avoid from being stacked and accumulated; needle holes are guaranteed to be full filled in the sheet without a dead angle.

Description

technical field [0001] The present invention relates to a punching machine, in particular to a mechanical sheet punching machine. Background technique [0002] As we all know, in order to make the object have strong air permeability and flammability, it is an effective way to increase air holes on the object. At present, the leading technology in China is Burfi Binson, which applies the punching technology to cloth, non-woven fabrics, metal films, plastic films, etc., and the ventilation effect of the products is very obvious. This punching technology has no precedent for effectively punching thin sheets with low tensile strength, easy to break, and containing a certain amount of moisture. There are two basic problems that need to be solved in the actual punching of low tensile strength, thinner, and water-containing sheets: 1. Low-strength and softer sheets are easy to run with the needle, resulting in rolling phenomenon, resulting in material accumulation on the needl...

Problems solved by technology

There are two basic problems that need to be solved in the actual punching of low tensile strength, thinner, and water-containing sheets: 1. Low-strength and softer sheets are easy to run with the needle, resulting in rolling phenomenon, resulting in material accumulation on the needle roller, which cannot be normal Operation; 2. Due to the tension during punching, it is very easy to cause breakage for the thin sheet with low tensile strength. Only by keeping the front and back of the thin sheet continuous can the punching be carried out normally, otherwise it will cause stacking and accumulation.
