Laser cleaning machine for cylindrical nickel screen

Abstract

The invention relates to a laser cleaning machine for a cylindrical nickel screen, and belongs to the technical field of laser cleaning devices. The laser cleaning machine comprises a machine body front portion, a machine body rear portion, a cylindrical nickel screen rotating mechanism, a tail bracket mechanism, a laser emission mechanism, a motor driving mechanism, a cleaning mechanism and a transmission mechanism. By using three groups of reflectors, through the reflective cooperation of the reflectors, the directions of the beams emitted by laser tubes are changed. In the cleaning process,the cylindrical nickel screen is rotated simply by moving the cleaning mechanism, and the space occupation of the device is reduced by fixing the laser tubes and changing the arrangement way of the laser tubes. An original arrangement way that the laser tubes are perpendicular to the nickel screen is replaced. The transverse distance between the beam focuses when lasers reach the cylindrical nickel screen is shortened, that is, when the cylindrical nickel screen is cleaned, the cleaning mechanism can move a shorter distance, and by means of the structure, the cleaning efficiency can be effectively improved. By using the cleaning structure which can move independently without moving the laser tubes or a power supply thereof, the load of a motor is greatly reduced, therefore, the motor which has lower technical parameters can be selected, and the cost is saved.

Description

technical field [0001] The invention specifically relates to a cylindrical nickel mesh laser cleaning machine, which belongs to the technical field of laser cleaning equipment. Background technique [0002] Rotary screen printing occupies the main market of textile printing in China. Its key component is seamless nickel rotary screen, referred to as nickel screen, which is usually made by electroforming, and its mesh is hexagonal. The pattern is printed on the nickel mesh by photosensitive method, and the photosensitive adhesive layer can be cleaned after use to realize the recycling of the nickel mesh. Laser technology can be used to remove photosensitive glue. The principle of laser removal of photosensitive glue is to irradiate the laser through optical focusing and then irradiate the part that needs to be cleaned. The laser energy can be highly concentrated in time and space, and the focused laser beam can produce several near the focus Thousands or even tens of thousan...

AI Technical Summary

Problems solved by technology

When the laser cleaning machine of the above technical solution is working, the vertically placed laser tube moves along the axis of the nickel mesh, resulting in an excessively large floor area of ​​the cleaning machine, and due to the influence of the diameter of the laser tube, the distance between the focusing mirrors is too large, resulting in cleaning relatively inefficient
