Static elimination equipment for cigarette package production and static elimination method thereof

Abstract

This invention provides a static elimination device and method during cigarette package production, wherein, the device comprises static generator on conveyer with static detectors 1 and 2 on front and back of the said generator and connected with the generator to form electric charge detection and feedback loop, they send the detected static polarity and voltage into generator to generate static charges with opposite polarity, then blowing the static to transparent paper material to balance the static, then feedbacking the detected result to generator. The invention solves problems in existing device, has simple structure, decides automatically the polarity, balances charge and eliminates static safely and quickly.

Description

technical field [0001] The invention relates to a device and a method for eliminating static electricity, in particular to a device and a method for eliminating static electricity generated during transportation of transparent paper materials used in packaging machines in the tobacco industry. Background technique [0002] The generation of static electricity is a very complicated process, which is related to many factors. When two different solids are in contact, the distance between them reaches or is less than 25×10 -8 cm, electron transfer will occur on the contact interface, the positive charge of losing electrons, and the negative charge of gaining electrons, that is, static electricity will be generated. The size of the electrostatic voltage depends on the physical and chemical properties of the two objects rubbing against each other, as well as the relative humidity, resistivity, number of objects, flow and friction time and speed of the location, etc. It is also di...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to solve the problem that the static elimination effect on the transparent paper packaging material in the tobacco industry is not good at present. In the process of eliminating static electricity, there is a zero-crossing point that cannot be automatically adjusted according to the static electricity intensity to neutralize the charge generation, and the transparent paper is easy to be damaged. Dangerous to the operator, provide a device in the form of detection and feedback that can control the polarity and strength of the neutralized charge, and eliminate static electricity by delivering ionized air to the surface of the transparent paper and eliminate The electrostatic method has the advantages of simple structure, convenient use, safety and reliability, and good static elimination effect.
