Description

Technical Field

[0001] The invention relates to the field of spraying technology, and in particular to a spraying device for processing a glass cover plate. Background Art

[0002] During the processing of glass cover plates, in order to enhance the light transmittance, anti-fingerprint and other properties of the glass cover plates, it is necessary to spray protective oil and other substances on the surface of the glass cover plates. The sprayed materials are generally harmful to the human body. Therefore, during the spraying process, an induced draft fan will be used to extract the sprayed materials that are not adsorbed on the glass cover plates during the spraying process out of the spray box. In the spraying of the prior art, the air inlet end of the exhaust pipe of the induced draft fan is usually arranged above the supporting platform on which the glass cover plates are placed. Since the spray gun sprays the mist-like spray onto the glass cover plates downward, and the exhaust direction of the induced draft fan is from bottom to top, the sprayed materials will form turbulence, which will be adsorbed on the surface of the glass cover plates to form foggy surface oil. The foggy surface oil needs to be wiped off manually later, which not only affects the yield rate of the glass cover plates, but also affects the spraying efficiency. Summary of the invention

[0003] In order to solve the technical problems existing in the background technology, the present invention provides a spraying device for processing a glass cover plate.

[0004] The spraying equipment for processing glass cover plates comprises a spray box, a spray gun assembly, a supporting platform and an induced draft fan assembly. The supporting platform is horizontally installed in the body of the spray box. The spray gun assembly comprises a spray gun. The spray gun needs to spray a mist flow downward to spray the glass cover plate placed on the supporting platform. The induced draft fan assembly comprises an induced draft fan and an exhaust pipe. The air outlet end of the exhaust pipe is connected with the air inlet of the induced draft fan. The air inlet end of the exhaust pipe passes through the body of the spray box and is connected with the inside of the spray box. The supporting platform is provided with a plurality of evenly distributed first through holes penetrating the top wall and the bottom wall of the glass cover plate. The air inlet end of the exhaust pipe is located below the supporting platform.

[0005] Preferably, the spraying equipment also includes a mist flow receiving part, which is installed in the box body of the spray box. The mist flow receiving part is a block with a receiving groove on the top, and the top wall of the receiving groove is abutted against the outer edge of the bottom wall of the supporting platform. A second through hole is provided on the side wall or the bottom wall of the mist flow receiving part, and the air inlet end of the exhaust pipe passes through the second through hole and is connected to the receiving groove and multiple first through holes on the supporting platform.

[0006] Preferably, a guide groove is opened on the top of the supporting platform, the first through holes are evenly distributed in the guide groove, and the spray gun sprays the glass cover plate placed in the guide groove. The peripheral wall boundary of the guide groove should slightly exceed the outer peripheral boundary of the glass cover plate.

[0007] Preferably, the mist flow receiving portion is made of a transparent material.

[0008] Preferably, the mist flow storage part includes a mist flow storage part body and a mist flow storage part mounting seat. The mist flow storage part mounting seat is fixedly installed in the box body of the spray box. The top of the mist flow storage part mounting seat is provided with an installation groove that is compatible with the mist flow storage part body and allows the mist flow storage part body to be nested therein.

[0009] Preferably, a plurality of supporting platforms are installed in the spray box, and the air inlet end of the exhaust pipe includes a plurality of branch air inlet ends, and a branch air inlet end is installed under each supporting platform.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] Since the air inlet end of the exhaust pipe is arranged below the supporting platform, it is ensured that the direction in which the spray material is sprayed out from the spray gun and the direction in which the excess spray material is extracted by the induced draft fan are both from top to bottom, thereby avoiding the formation of turbulence of excess spray material that will be adsorbed on the surface of the glass cover plate to form foggy surface oil, thereby greatly reducing the subsequent workload of manually wiping the foggy surface oil on the glass cover plate, while also improving the yield rate of the glass cover plate, in addition, it also reduces the spray material adsorbed on the box wall of the spray box, and also reduces the damage of the spray material to the operator.

[0012] A mist collection section is provided to seal the lower space of the support platform and the air inlet end of the exhaust pipe, so as to further reduce the probability of excess spray spreading in the spray box body to form misty surface oil on the surface of the glass cover plate, thereby further ensuring the pollution-free spraying effect of the glass cover plate.

[0016] The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] refer to Figures 1 to 3, a spraying device for processing a glass cover plate comprises a spray box 1, a spray gun assembly, a carrying platform 2, and an induced draft fan assembly. The carrying platform 2 is horizontally installed in the body of the spray box 1. The spray gun assembly comprises a spray gun 3. The spray gun 3 needs to spray a mist flow downward to spray the glass cover plate placed on the carrying platform 2. The induced draft fan assembly comprises an induced draft fan and an exhaust pipe 4. The exhaust pipe 4 has an air outlet connected to an air inlet of the induced draft fan. The exhaust pipe 4 has an air inlet end that passes through the body of the spray box 1 and is connected to the inside of the spray box 1. The carrying platform 2 is provided with a plurality of evenly distributed first through holes 2a that penetrate the top wall and the bottom wall of the glass cover plate. The exhaust pipe 4 has an air inlet end that is located below the carrying platform 2.

[0018] Since the spray is sprayed from the spray gun 3 from top to bottom, and the excess spray not adsorbed on the glass cover is also drawn out by the induced draft fan from top to bottom, it is avoided that the excess spray forms turbulent flow that will be adsorbed on the surface of the glass cover to form foggy surface oil, thereby greatly reducing the workload of subsequent manual wiping of the foggy surface oil on the glass cover, while also improving the yield rate of the glass cover, in addition, it also reduces the spray adsorbed on the box wall of the spray box 1, and also reduces the damage of the spray to the operator.

[0019] The spraying equipment also includes a mist flow receiving part 5, which is installed in the box body of the spray box 1. The mist flow receiving part 5 is a block with a receiving groove 5a on the top. The top wall of the receiving groove 5a is abutted against the outer edge of the bottom wall of the supporting platform 2. A second through hole 5b is provided on the side wall or bottom wall of the mist flow receiving part 5. The air inlet end of the exhaust pipe 4 passes through the second through hole 5b and is connected with the receiving groove 5a and multiple first through holes 2a on the supporting platform 2.

[0020] In order to further reduce the probability of excess spray spreading in the spray box 1 to form foggy surface oil on the surface of the glass cover, a mist flow receiving section 5 is provided to seal the lower space of the supporting platform 2 and the air inlet end of the exhaust pipe 4, thereby further ensuring the pollution-free spraying effect of the glass cover.

[0021] A guide groove 2b is provided on the top of the supporting platform 2, and the first through holes 2a are evenly distributed in the guide groove 2b. The spray gun 3 sprays the glass cover plate placed in the guide groove 2b. The peripheral wall boundary of the guide groove 2b should slightly exceed the outer peripheral boundary of the glass cover plate. The guide groove 2b will better introduce the excess spray on the supporting platform 2 into the mist flow receiving portion 5 located below it to avoid its adsorption on the glass cover plate to cause spray pollution to the glass cover plate.

[0022] The mist flow receiving portion 5 is made of a transparent material, which facilitates observation of the amount of sprayed material stored in the receiving groove 5 a, so that the sprayed material in the receiving groove 5 a can be removed in time, thereby ensuring the working reliability of the mist flow receiving portion 5 .

[0023] The mist flow receiving portion 5 comprises a mist flow receiving portion body 50 and a mist flow receiving portion mounting seat 51. The mist flow receiving portion mounting seat 51 is fixedly mounted in the body of the spray box 1. A mounting groove 51a which is matched with the mist flow receiving portion body 50 and allows the mist flow receiving portion body 50 to be nested therein is provided on the top of the mist flow receiving portion mounting seat 51. If there is too much spray in the storage groove 5a, it is only necessary to take the mist flow receiving portion body 50 out of the mist flow receiving portion mounting portion 51, remove the spray therein, and then put it back into the mounting groove 51a, thereby reducing the workload of removing the spray.

[0024] A plurality of supporting platforms 2 are installed in the spray box 1, and the air inlet end of the exhaust pipe 4 includes a plurality of branch air inlet ends 41. A branch air inlet end 41 is installed under each supporting platform 2, so as to improve the spraying efficiency.
