Abstract
The utility model relates to a laser device for cutting plastic films, which is mainly composed of a laser generator, an optical path passage and a cutting head, wherein, the cutting head is provided with an aperture diaphragm inside. The utility model can better ensure the quality of the cut of films. When the device is used for cutting plastic films in production lines without contacts, particularly composite films, the utility model solves the problem of loss caused during contact cutting by using blades made of any material. The utility model can work durably without maintenance and has increased production efficiency.
Description
The utility model relates to a kind of laser aid that plastic sheeting is used that cuts, and relates in particular to the laser cutting head that is used for the continuous cutting at plastic sheeting edge on the production line.
The cutting of plastic sheeting on the current product line generally adopts the blade of metal or other material to carry out the contact cutting.When cutting contained the laminated film of a considerable amount of inorganic components, the wearing and tearing of blade were very obvious.As can not regularly being changed in time, tend to so cause exception parking, production efficiency is greatly reduced, and bring economic loss.Use the blade of unlike material instead, also can not fundamentally solve the wear problem of blade in the contact cutting.
The purpose of this utility model is the deficiency at above-mentioned prior art, proposes a kind of non-contact plastic thin-film cutter, i.e. the incisory laser aid of plastic sheeting continuous edge on production line.
Task of the present utility model, can finish by following design: main by the laser generator that is used to produce lasing light emitter, have the path channels of speculum and cutting head and constitute, it is characterized in that cutting head inner focusing mirror the place ahead is equipped with the aperture diaphragm of an aperture less than lasing beam diameter.The effect of aperture diaphragm be will be the peripheral edge portion that distributes of Gauss's luminous energy blocked, make hot spot after the light beam line focus can satisfy the quality requirement of film cutting, reduce the loss that fuel factor causes.
The laser aid that adopts the utility model to provide, can be that the plastic sheeting of 15～100um, linear velocity 80～300m/min or the laminated film that is added with inorganic matter carry out contactless cutting to the thickness that moves on the production line, compared with prior art fundamentally solved in the contact cutting, because the scram that blade abrasion causes.The cutting head that particularly adopts aperture diaphragm to constitute can make otch smooth smooth, and non-maintaining continuous production is enhanced productivity more than 10,000 hours greatly, reduces the finished product loss.
Accompanying drawing is the laser aid structural representation.
Below in conjunction with accompanying drawing the utility model is further described.
In the utility model structure was formed, it was the CO of basic mode that laser generator is preferably selected output mode for use
2Laser instrument (1).For guaranteeing the safety of operating personnel on the production line, path channels adopts the totally enclosed type pipeline configuration, even light path is advanced along pipeline (2), at the pipeline turning point, interior angle is equipped with speculum (3).Cutting head (9) outer tube top is straight tube-like, and it is conical that the bottom is, and is provided with through hole (8) at the vertex of a cone, so that focused beam passes through.Straight tube is provided with a pore (5), can pass to gas with various according to cutting object, prevents from that vapour is dirty to hide focus lamp, or passes to inert gas and prevent the overheated burning of film.
Cutting head (9) is fixed on the support (4) that can adjust vertically.The aperture diaphragm (6) of an aperture less than lasing beam diameter is equipped with in cutting head inner focusing mirror (7) the place ahead, to block the edge hot spot, guarantees that the otch (10) of film (11) is smooth smooth, satisfies quality requirement.
Claims (1)
1, a kind of cutting plastic sheeting laser aid by laser generator, has the path channels of speculum and cutting head and constitutes, and it is characterized in that cutting head inner focusing mirror the place ahead is equipped with the aperture diaphragm of an aperture less than lasing beam diameter.
