Automatic spraying device for plastic shell processing

Abstract

According to the automatic spraying device for machining the plastic shell, in the working process, the plastic shell to be sprayed is fixed in the spraying box through the fixing mechanism, and the XY moving platform drives the spraying nozzle to conduct moving spraying on the plastic shell to be sprayed. In the process, the spraying machine supplies materials to the spraying nozzle through the spraying hose, and spraying operation is conducted on the to-be-sprayed plastic shell in combination with the XY moving platform. In the spraying process or after spraying operation is completed, the exhaust fan works to suck waste gas in the spraying box into the adsorption barrel, so that the waste gas spirally ascends through the spiral blade, and in the process that the waste gas spirally ascends in the waste gas adsorption barrel, coating particles in the waste gas can be effectively adsorbed through the blade mud arranged on the two faces of the spiral blade. The waste gas is pumped to the adsorption box by the exhaust fan after passing through the adsorption barrel, so that harmful substances and peculiar smell in the waste gas are further adsorbed by activated carbon in the adsorption box. After being treated by activated carbon, the gas is discharged from the top of the adsorption box.

Description

Technical Field

[0001] The utility model relates to the field of plastic shell spraying, in particular to an automatic spraying device for plastic shell processing. Background Art

[0002] Plastics are polymer compounds that are polymerized from monomers through addition polymerization or condensation polymerization. The main component of plastics is resin. Resin refers to polymer compounds that have not been mixed with various additives. The term resin was originally named after the lipids secreted by animals and plants, such as rosin and shellac. Resin accounts for about 40% to 100% of the total weight of plastics. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Plastics are important organic synthetic polymer materials and are widely used. Plastics can be divided into two categories: thermosetting and thermoplastic. The former cannot be reshaped and used, while the latter can be repeatedly produced. Thermoplastic has a large physical elongation, generally between 50% and 500%. The force does not change completely linearly at different elongations.

[0003] However, plastic has good corrosion resistance and oxidation resistance, and is low in cost. It is widely used in protective shells of various electrical appliances. In order to increase the oxidation resistance and ornamental properties of plastic shells, the plastic shells are sprayed with antioxidant coatings.

In this way, it is convenient for the fixing mechanism 300 to fix the plastic shell to be sprayed.

[0034] In order to increase the working stability of the fixing mechanism 300, in one embodiment, the fixing mechanism 300 further includes a receiving assembly 340, which includes a receiving plate 341, a rotating plate 342, a rotating plate 343 and a plurality of connecting rods 344.

[0036] During the operation of the automatic spraying device 10 for plastic shell processing, the plastic shell to be sprayed is fixed in the spray box 100 through the fixing mechanism 300, and the XY moving platform 230 drives the spray nozzle 240 to move and spray on the plastic shell to be sprayed. In this process, the sprayer 210 feeds the spray nozzle 240 through the spray hose 220, and the plastic shell to be sprayed is sprayed in combination with the XY moving platform 230. During the spraying process or after the spraying operation is completed, the exhaust fan 420 works to draw the waste gas in the spray box 100 into the adsorption cylinder 410, so that the waste gas spirally rises through the spiral blade 412. During the spiral rising process in the waste gas adsorption cylinder 410, the leaves and muds set on both sides of the spiral blade 412 can effectively adsorb the paint particles in the waste gas. After passing through the adsorption cylinder 410, the waste gas is pumped to the adsorption box 430 by the exhaust fan 420, so that the activated carbon in the adsorption box 430 further adsorbs the harmful substances and odors in the waste gas. After being treated with activated carbon, it is discharged from the top of the adsorption box 430. The above-mentioned automatic spraying device for plastic shell processing avoids pollution to the surrounding environment and harm to the health of workers during the spraying of the plastic shell.
