Description

Technical Field

[0001] The present application relates to the field of spraying technology, and in particular to an aluminum veneer spraying device. Background Art

[0002] Aluminum veneer is a type of metal decorative panel. It has the advantages of light texture, excellent resistance to cold and heat, ability to resist strong ultraviolet radiation, ability to remain non-fading and non-powdering for a long time, and long service life. Therefore, aluminum veneer is widely used in architectural decoration.

[0003] During the processing of aluminum veneer, its surface needs to be painted. When painting, in order to improve efficiency, most of the time a continuous painting device is used, that is, the aluminum veneer is hoisted on a hanging chain and passed through a paint spray box or a paint spray room in turn. The nozzle in the paint spray box (room) sprays the aluminum veneer with paint. Since the aluminum veneer is usually in an exposed state during production and processing, and needs to be moved a certain distance to the paint spray box (room) when hanging on the chain, some dust and debris may adhere to its outer surface. When the aluminum veneer is being painted, the paint surface will be rough due to the influence of debris and dust, thereby reducing the overall spraying effect of the aluminum veneer. Therefore, the present application proposes an aluminum veneer spraying device. Summary of the Invention

[0004] The purpose of this application is to solve the problem that when the existing spraying device sprays aluminum veneer, the dust attached to the surface of the aluminum veneer affects the spraying effect. This application provides an aluminum veneer spraying device.

[0005] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] like Figures 1-8 As shown, an aluminum veneer spraying device proposed in one embodiment of the present application includes:

[0031] A frame 1 is provided with a spray box 2 on the top thereof. A feed trough 3 is provided on both opposite sides of the spray box 2. A spray mechanism 4 is provided inside the spray box 2. The feed trough 3 is used for the chain and the suspended aluminum veneer to pass through. The spray mechanism 4 is used to spray the surface of the aluminum veneer;

[0032] The cleaning mechanism 5 includes two rotating shafts 501 rotatably arranged at one end of the frame 1 and located on both sides of the feed chute 3. Two rubber discs 502 are fixed on the rotating shafts 501. When the aluminum veneer is suspended on the chain and moved for transmission, the four rubber discs 502 respectively resist the upper and lower ends of the aluminum veneer. A sleeve 503 is rotatably sleeved on the rotating shaft 501 and located between the two rubber discs 502. An elastic cleaning member 504 is provided on the sleeve 503. A driving member 505 for driving the two rotating shafts 501 to rotate synchronously in the opposite direction is provided on the frame 1. When the aluminum veneer is transmitted, the driving member 505 drives the two rotating shafts 501 to rotate synchronously in the opposite direction. The two corresponding rubber discs 502 on the two rotating shafts 501 rotate and resist the aluminum veneer. And to assist the transmission of the aluminum veneer, a linkage member 506 is provided between the rotating shaft 501 and the sleeve 503. When the rotating shaft 501 rotates, the linkage member 506 drives the sleeve 503 to rotate in the opposite direction synchronously. When the rotating shaft 501 rotates, the linkage member 506 drives the sleeve 503 to rotate in the opposite direction synchronously. At this time, the two corresponding rubber discs 502 assist in the transmission of the aluminum veneer and limit the transmission of the aluminum veneer so that it remains in a vertical state during transmission. At this time, the elastic cleaning member 504 contacts the surface of the aluminum veneer and rotates to clean the surface of the aluminum veneer. Since the rotation direction of the elastic cleaning member 504 is opposite to that of the rubber disc 502, it can not only effectively clean and remove dust from the surface of the aluminum veneer, but also does not affect the normal transmission of the aluminum veneer.

[0033] The dust-proof mechanism 6 is arranged on the frame 1, and is used to extract the cleaned dust to prevent the dust from flying and escaping. The dust-proof mechanism 6 is set to extract the cleaned dust to prevent the cleaned dust from flying, which not only prevents the flying dust from affecting the subsequent transmission of the aluminum veneer, but also improves the air environment hygiene of the work station. The overall structure of the device is that the shaft 501 and the sleeve 503 rotate synchronously in opposite directions. When the shaft 501 rotates, the rubber disc 502 assists in the transmission of the aluminum veneer and vertically limits it during transmission to prevent it from shaking. When the sleeve 503 rotates, the elastic cleaning member 504 rotates to clean the surface of the aluminum veneer, and the rotation cleaning direction is opposite to the transmission direction of the aluminum veneer. The opposite stress is used to make the cleaning effect of the aluminum veneer surface better, and the subsequent spraying effect of the aluminum veneer better.

[0034] like Figure 7As shown, in some embodiments, the driving member 505 includes a dual-axis motor 5051 arranged at the bottom of the frame 1, and the two output shaft ends of the dual-axis motor 5051 are fixed with a transmission bevel gear 5052, and the two rotating shafts 501 are fixed with a driven bevel gear 5053, and the two driven bevel gears 5053 are respectively engaged with the teeth of the two transmission bevel gears 5052. The dual-axis motor 5051 is well made, and its two output shafts rotate synchronously in the same direction, thereby driving the two transmission bevel gears 5052 to rotate synchronously, and the two transmission bevel gears 5052 are respectively engaged with the teeth of the two driven bevel gears 5053, thereby driving the two rotating shafts 501 to rotate synchronously. Since the two transmission bevel gears 5052 are relatively arranged, the two rotating shafts 501 rotate synchronously in opposite directions.

[0035] like Figure 6 As shown, in some embodiments, the linkage member 506 includes a shaft 5061 rotatably set on the frame 1, and a circular gear 5062 is fixed on the shaft 5061 and the rotating shaft 501, and the two circular gears 5062 are engaged with each other. A pulley assembly 5063 is connected between the shaft 5061 and the sleeve 503. When the rotating shaft 501 rotates, the shaft 5061 rotates synchronously in the opposite direction under the engagement of the teeth of the two circular gears 5062, and the linkage of the pulley assembly 5063 achieves the effect of driving the sleeve 503 to rotate synchronously in the opposite direction.

[0036] like Figure 4 As shown, in some embodiments, the elastic cleaning member 504 includes a mounting sleeve 5041 fixed on the sleeve 503, and the outer surface array of the mounting sleeve 5041 is provided with a plurality of foam strips 5042 distributed in a ring shape. Preferably, the outer diameter of the circle formed by the plurality of foam strips 5042 is larger than the outer diameter of the rubber disc 502. Since the material of the foam strip 5042 is deformable, when the rubber disc 502 overlaps with the outer surface of the aluminum veneer, the foam strip 5042 will also overlap with the surface of the aluminum veneer and will be compressed to a certain extent, so that when the sleeve 503 rotates, the foam strip 5042 has a better cleaning effect on the aluminum veneer.

[0037] like Figure 1 and Figure 2As shown, in some embodiments, the dustproof mechanism 6 includes two dustproof shells 601 provided on the frame 1, and openings are configured on opposite sides of the two dustproof shells 601. The cross-section of the dustproof shells 601 is tapered, and the opening is located at one end of the tapered expansion. The two rotating shafts 501 are respectively located in the two dustproof shells 601. When cleaning, the cleaned dust will float in the two dustproof shells 601. The two dustproof shells 601 are connected to an air duct 602, and the free ends of the two air ducts 602 are connected to The three-way air pipe 603, the free end of the three-way air pipe 603 is connected to the exhaust fan 604, and the three-way air pipe 603 is provided with a filter element 605. The exhaust fan 604 works to generate suction, which is applied to the dustproof shell 601 through the three-way air pipe 603 and the two air guide pipes 602. Under the action of the suction, the swept dust will be sucked into the air guide pipe 602 along with the wind flow and filtered through the filter element 605 to ensure that the dust will not be directly dissipated to the outside world, thereby playing a dust-proof role.

[0038] like Figure 8 As shown, in some embodiments, the filter element 605 includes a filter cartridge 6051 connected to the three-way air pipe 603, and a filter screen 6052 is arranged in the filter cartridge 6051. Preferably, the three-way air pipe 603 includes a first tube body and a second tube body, and the first tube body and the second tube body are respectively connected to the upper and lower ends of the filter cartridge 6051. The end of the second tube body portion extends into the filter cartridge 6051 and is constructed with a conical expansion mouth. The filter screen 6052 has a conical structure and is arranged on the conical expansion mouth. The filter screen 6052 not only effectively filters and intercepts dust in the air, but also prevents it from being covered by dust, thereby ensuring the air ventilation volume. Preferably, a discharge port is opened through one side of the filter cartridge 6051, and a cover plate covering the discharge port is provided on the filter cartridge 6051, so as to facilitate the cleaning of the intercepted dust.

[0039] like Figure 5 As shown, in some embodiments, rubber rollers 7 are rotatably provided at both ends of the opening of the dustproof shell 601. The provided rubber rollers 7 can not only assist the rubber disc 502 in assisting the transmission of the aluminum veneer, so that the aluminum veneer remains upright during transmission, making it easier for the cleaning mechanism 5 to clean it, but also are used to reduce the gap between the two dustproof shells 601, so that the dust extraction effect is better under the extraction of wind, and the dust is better prevented from overflowing and floating.

[0040] like Figure 3As shown, in some embodiments, the spraying mechanism 4 includes two nozzles 401 with open tops, and the two nozzles 401 are respectively arranged on opposite sides of the inner wall of the spray box 2. The free ends of the two nozzles 401 are connected to a three-way delivery pipe 402, and the nozzles 401 are connected to a plurality of nozzles 403 in an array along their height direction. Preferably, the free end of the three-way delivery pipe 402 is connected to an external paint equipment, and the external paint raw materials will be transported to the two nozzles 401 through the three-way delivery pipe 402, and the paint in the nozzles 401 will be sprayed out through the plurality of nozzles 403, thereby spraying both sides of the aluminum veneer.

[0041] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
