Problems solved by technology

Pre-drilling is often used in production, that is, electrostatic or laser drilling is performed on the splicing line in advance, but most of the products currently seen are one to two rows of holes, which cannot meet the required air permeability, and the efficiency is low. There is no equipment capable of producing high-transparency tipping paper for punching thin substrates. In addition, no qualified high-transparency packaging paper has been produced by changing the paper production process during production.

Abstract

The present invention relates to electrically perforating, and is especially one wide coverage perforating apparatus for thin base material. The perforating apparatus consists of unwinding mechanism, winding mechanism, correction controller, tension controller, hydraulic mechanism, perforating mechanism, HF high voltage generator, detection mechanism, speed, frequency and pulse width controller, and man-machine interface. It features the perforating mechanism comprising at least two electrode matrixes, each of which consists of two, including one positive and one negative, electrodes set on two sides of the base material separately, in some angle to the base material motion direction and with M electrode pins. The present invention has the advantages of multiple perforating, capacity of perforating in millimeter level narrow strip and capacity of perforating in meter level broad width.

Description

Technical field: [0001] The invention relates to the field of electric punching, in particular to punching equipment for wide and thin substrates. Background technique: [0002] The use of thin substrates is extremely wide, especially in some fields, the use of thin substrates requires a certain tensile strength and a certain degree of air permeability or other characteristics caused by micropores. In the current cigarette manufacturing industry, in order to reduce tar smoking One of the effective methods is to perforate cigarettes and tipping paper to increase their air permeability and reduce tar content. At present, there are mostly two ways of punching tipping paper, that is, online punching or pre-punching. Pre-drilling is often used in production, that is, electrostatic or laser drilling is performed on the splicing line in advance, but most of the products currently seen are one to two rows of holes, which cannot meet the required air permeability, and the efficiency...
