Description

Mirror blasting processing unit

Technical field

The utility model is related to mirror process equipment, more specifically, it relates to a kind of mirror blasting processing unit.

Background technology

Mirror blasting processing unit is a kind of is used for mirror progress sandblasting, to remove the device of silver coating.

At present, in the market in order to solve the problems, such as that traditional mirror can only use in the case of bright and clear, design production A kind of new-type mirror -- lamp mirror.

Lamp mirror is usually LED light mirror, is that the mirror back side is handled, to remove silver coating so that glass is in the position In translucent construction, and the position installation LED light source mirror, can in the environment of insufficient light normal use.

When removing silver coating to the mirror back side, people's generally use blasting craft, which is：First at the mirror back side not Stick a kind of protective layer in position to be treated（Adhesive tape may be employed）, spray gun is recycled to project high speed grains of sand strike mirror afterwards The silver coating at the back side to remove silver coating, achievees the purpose that make mirror cooperated with LED light source to be facilitated to process in designated position light transmission Into lamp mirror.

When carrying out blasting treatment to mirror, there are such a problems：Mirror is sprayed in staff's pistol During sand, roughing sand is sprayed on mirror after use at a high speed by spray gun, can be sputtered towards surrounding, substantial amounts of particle is discharged into air Object pollutes environment.

A kind of new following spray glass-sandblasting device, technology disclosed in the Chinese patent of Publication No. CN204053807U Main points are：Including operating room, the front end of the operating room is equipped with input belt, the operating room be internally provided with mould bases, slide bar, Sucker pressing plate, the mould bases are arranged on the bottom surface of operating room, and the model sheetinstallat is on mould bases, between the template and mould bases Closed sandblasting chamber is formed, the sandblasting intracavitary sets suction feed type gun, and the slide bar is arranged on the upside of mould bases, the sucker Pressing plate is mounted on by lifting shaft on slide bar.

In use, glass is first placed on input belt by staff, glass is sent into inside working chamber by input belt, is risen It is flexible up and down that axis control sucker pressing plate drops, while sucker pressing plate slidably reciprocates along slide bar glass moving on to template upper end, afterwards Suction feed type gun starts carries out blasting treatment to glass, and the roughing sand of ejection is obstructed by mould bases, big so as to avoid discharging into air The particulate matter of amount.

The problem of a large amount of particulate matters are discharged when solving sandblasting in said program into air, pollute environment, but because In use, it is to recycle that the suction feed type gun being connected to below template is set to carry out at sandblasting after glass is placed in template At this time because suction feed type gun is irremovable, it is uneven that sandblasting polishing is usually present with when carrying out sandblasting to mirror for reason The phenomenon that, close to the position at middle part, polishing is deeper, and the place polishing at close edge is shallow or even silver coating is not removed to clean, shadow Ring using effect when lamp mirror is subsequently made.

Therefore need to propose a kind of new scheme to solve the problems, such as this.

Utility model content
