Environment-friendly LED lamp diffusion sheet spraying device

Technical Field

The invention relates to the technical field of spraying of LED lamps, in particular to a spraying device for a diffusion sheet of an environment-friendly LED lamp.

Background

The LED lamp is popular with consumers due to energy conservation and environmental protection, is fashionable and gorgeous in appearance, can play a basic role in illumination at home and in workplaces, can play a good decoration and embellishing role, belongs to the components of the LED lamp, and needs to be sprayed with dye chemical substances in the production process to improve the performance of the LED lamp.

For example, chinese patent that publication number is CN109433492A discloses an led lamp spraying equipment of environmental protection net flavor, including conveying pipe, bearing seat, protruding platform and base, conveying pipe runs through the inside and shower nozzle threaded connection in top of spraying box, the bearing seat sets up the inside below at the spraying box, protruding platform sets up the inside top at the bearing seat, place the seat and run through protruding platform and bearing seat and first connecting axle interconnect, the outside of first connecting axle is connected with the connection belt, the top bilateral symmetry of base is provided with first motor, the front surface of spraying box rotates and is connected with the guard plate, all seted up the perforation on first connecting axle and the second connecting axle. This led lamp spraying equipment of environmental protection net flavor, through the setting of the bellying platform of conical structure for unnecessary dyestuff that the shower nozzle sprayed can be through the lateral wall landing downwards of bellying platform, and fall into in the bearing seat, thereby avoided the dyestuff distribution to pollute the inboard of spraying box.

But it still can have the condition that the dyestuff appears spattering outward and splashing at the in-process of concrete spraying, leads to the dyestuff extravagant in the time, on the dyestuff spattered the diapire in the spraying case, and it is more troublesome to need follow-up clearance to carry out.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide the spraying device for the diffusion sheet of the environment-friendly LED lamp, which can effectively prevent the dye from splashing during spraying.

The above object of the present invention is achieved by the following technical solutions:

the utility model provides an environmental protection led lamps and lanterns diffusion piece spraying device, includes the organism, be provided with the spray booth in the organism, be provided with the holder that is used for the centre gripping product in the spray booth, the top and the bottom of holder are provided with top cap and end cover respectively, the equal vertical sliding connection of top cap and end cover is in the spray booth, be provided with the first driving piece of ordering about top cap and end cover lift on the organism, the top cap inner wall is provided with the nozzle.

Like this when concrete spraying, the product that will treat the spraying is fixed with the help of the holder, then removes in opposite directions through ordering about the overhead guard and end cover and realize the closure, cover the product in inside, then spray with the help of the nozzle on the overhead guard, the dyestuff is blockked comprehensively by overhead guard and end cover during the spraying, can prevent effectively splashing of dyestuff, just avoid the dyestuff to splash to the condition that the bottom wall of spray booth leads to follow-up needs to clear up when reducing extravagant, make the inside clean and tidy nature of spray booth better.

The present invention in a preferred example may be further configured to: the bottom of the bottom cover is connected with a discharge pipe, and the end part of the discharge pipe is connected with a storage box.
