DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1 Reference Figure 1-Figure 3 , topcoat spraying equipment, which is used in the field of aluminum spray painting, mainly includes a base plate 1 and a plurality of base plates 8 located above the base plate 1. The top of the base plate 1 is fixed with a spray box 2 and a drying box 3 from left to right, and both sides of the two boxes are provided with openings to facilitate the movement of the aluminum cabinet. A groove 4 is designed at the top of the base plate 1, and a conveyor chain 5 is arranged in the groove 4. The conveyor chain 5 is used to convey the aluminum cabinet to the spray box 2 and the drying box 3 in turn.

[0022] Reference Figure 3 , Figure 4 and Figure 6 A top plate 10 is fixed to the top inner wall of the spray box 2. A plurality of electromagnetic spray heads 21 and two groups of spray components are respectively arranged below the top plate 10. Each group of spray components is composed of a plurality of nozzles 15. These electromagnetic spray heads 21 and the spray components jointly complete the paint spraying on the aluminum cabinet surface.

[0023] Reference Figure 3-Figure 5In order to realize the spraying of the side of the aluminum cabinet, a first spraying structure is provided. The structure includes a bidirectional screw 11 which is rotatably connected to the bottom of the top plate 10 through a base plate. The outer wall thread sleeve of the bidirectional screw 11 is provided with two frames 13, and the two frames 13 are respectively located on the positive and negative thread segments of the bidirectional screw 11. At the bottom of the top plate 10, a fixed rod 12 is also fixed through the base plate, and the two frames 13 are slidably connected to the fixed rod 12. The cooperation between the bidirectional screw 11 and the frame 13 can control the spacing between the two frames 13. In each frame 13, a first movable plate 14 is slidably connected, and the sides of the two first movable plates 14 close to each other are fixedly connected to the two spraying components. On the sides away from each other, a first liquid storage pipe 17 is fixed respectively, and the spraying component is connected to the adjacent first liquid storage pipe 17. In each frame 13, a screw rod 16 is rotatably connected, and the screw rod 16 is threadedly connected to the first movable plate 14, so as to enable the spraying component to spray paint evenly on the aluminum cabinet surface.

[0024] Reference Figure 2 and Figure 4 A storage box 48 is fixed on the top of the spray box 2 for containing paint. A water pump 18 is also fixed on the top inner wall of the spray box 2. The liquid inlet end of the water pump 18 is connected to the storage box 48 through a hose, and a first liquid delivery pipe 19 is fixed to the liquid outlet end through a hose. The two ends of the first liquid delivery pipe 19 are respectively connected to the two first liquid storage pipes 17 for delivering paint to the first liquid storage pipes 17.

[0025] Specifically, when working, the water pump 18 will inject the paint in the storage box 48 into the first liquid storage tube 17, and then the paint will be evenly sprayed on the two cabinet surfaces of the aluminum cabinet through the nozzle 15. Then, the motor drives the screw 16 to rotate, and the screw 16 will drive the first movable plate 14 to move, and then the cabinet surface can be evenly sprayed with paint through the cooperation of the first movable plate 14 and the nozzle 15. When the supporting platform 9 rotates, the screw 16 will drive the first movable plate 14 to move, and the nozzle 15 can spray the paint on the other two cabinet surfaces of the aluminum cabinet.

[0026] Reference Figure 5-Figure 8In order to realize the spraying of the top surface of the aluminum cabinet, a second spraying structure is set. This structure includes a second liquid storage tube 20 fixed at the bottom of the top plate 10, and multiple electromagnetic spray heads 21 are fixed at the bottom of the second liquid storage tube 20. A second infusion tube 22 is fixed on the top of the second liquid storage tube 20, and the second infusion tube 22 is connected to the first infusion tube 19. At the top of the bottom plate 8, a bearing platform 9 is rotatably connected, and the bearing platform 9 is used to carry the aluminum cabinet. A motor for driving the bearing platform 9 to rotate is provided in the bottom plate 8. When the bottom plate 8 is set on the conveyor chain 5, the conveyor chain 5 will convey the bottom plate 8. A semicircular ring 24 is fixedly sleeved on the outer wall of the bearing platform 9. At the top of the base plate 1, a fixed seat 25 is fixed, and a plug rod 26 that cooperates with the semicircular ring 24 is slidably penetrated in the fixed seat 25. The function of the semicircular ring 24 is to push the plug rod 26 outward. A tension spring 27 is sleeved on the outer wall of the plug rod 26, one end of the tension spring 27 is fixedly connected to the side of the fixed seat 25 away from the support platform 9, and the other end is fixedly connected to the outer wall of the plug rod 26. An L-shaped frame 29 is also fixed on the side of the fixed seat 25 away from the support platform 9, and a second touch piece 30 is fixed on one side of the L-shaped frame 29. A first touch piece 28 is fixed to the end of the plug rod 26 away from the support platform 9. The first touch piece 28 and the second touch piece 30 are both electrically connected to the electromagnetic nozzle 21, and when they cooperate, the electromagnetic nozzle 21 can be energized.

[0027] Specifically, during operation, the motor provided in the bottom plate 8 drives the support platform 9 to rotate, driving the aluminum cabinet to rotate 180°. During the rotation of the support platform 9, the inclined surface at one end of the semicircular ring 24 will cooperate with the insertion rod 26, driving the insertion rod 26 and the first touch piece 28 to move outward. When the first touch piece 28 touches the second touch piece 30, the electromagnetic spray head 21 will be energized. Therefore, during the rotation of the support platform 9, the electromagnetic spray head 21 can spray the top cabinet surface of the aluminum cabinet. The insertion rod 26 will not reset until it loses the resistance of the semicircular ring 24.

[0028] Reference Figure 3 and Fig. 9 A drying structure is provided in the drying box 3, which is used to dry the paint on the aluminum cabinet surface and remove the paint odor. A plurality of first fans 32 are fixedly installed on the top of the drying box 3. The function of these first fans 32 is to extract air from the outside and introduce the air into the drying box 3, which is mainly used to dry the top surface of the aluminum cabinet. In order to ensure the drying effect, a plurality of second fans 33 are also provided on the inner walls of the two sides of the drying box 3 that are far away from each other. These second fans 33 work in coordination with the first fans 32 to dry the cabinet surface of the aluminum cabinet in all directions.

[0029] A plurality of heating plates are also fixed to the top inner wall of the drying box 3. The function of these heating plates is to heat the air entering the drying box 3, increase the temperature of the air, thereby accelerating the evaporation of water on the aluminum cabinet surface, and achieving the purpose of rapid drying.

[0030] Reference Fig. 9 In addition, in order to deal with the paint odor that may be generated during the drying process, the device is fixed with two water tanks 35 on the top of the base plate 1. The two water tanks 35 contain salt water, and the characteristic of salt water is that it can absorb harmful substances such as formaldehyde in paint. The two water tanks 35 are respectively located on both sides of the drying box 3 to facilitate the treatment of the odorous air discharged from the drying box 3.

[0031] Reference Fig. 9 In order to achieve this function, air pumps 34 are fixed on both sides of the drying box 3. The air inlet ends of the two air pumps 34 extend into the drying box 3 through pipes, and the air outlet ends extend into the corresponding water tanks 35 through pipes. When the drying operation is performed in the drying box 3, the air pumps 34 will start to extract the air containing the paint odor from the drying box 3 and discharge it into the water tank 35. The salt water in the water tank 35 is used to adsorb the odorous air, thereby preventing the odorous air from being directly discharged into the environment and causing air pollution.

[0032] Specifically, when the aluminum cabinet is sent into the drying box 3, the first fan 32 starts to work, extracts air from the outside and introduces it into the drying box 3. At the same time, the heating plate also starts to heat up to increase the temperature of the air in the drying box 3. Then, the first fan 32 and the second fan 33 are started at the same time to blow and dry the cabinet surface of the aluminum cabinet. During the drying process, the air pump 34 will continuously extract the odorous air in the drying box 3 and discharge it into the water tank 35 for treatment.

[0033] Reference Figure 7 and Figure 8 Both ends of the semicircular ring 24 are designed with inclined surfaces. These inclined surfaces cooperate with the insertion rod 26. When the frame 13 moves toward the middle, the inclined surfaces of the semicircular ring 24 will push the insertion rod 26 to move outward. This design enables the electromagnetic nozzle 21 to automatically adjust the spraying range as needed during the spraying process to avoid waste of raw materials.

[0034] Reference Figure 6 A baffle 23 is also fixed on the top of the frame 13. The baffle 23 is used to close the electromagnetic nozzles 21 at the edge when the frame 13 moves toward the middle. Because when the nozzle 15 is close to the aluminum cabinet for spraying, if the electromagnetic nozzles 21 at the edge continue to spray, it will cause a waste of raw materials. The setting of the baffle 23 just solves this problem. It can automatically close the electromagnetic nozzles 21 at the edge when the frame 13 moves, ensuring the accuracy and efficiency of spraying.

[0035] Reference Figure 3 A groove 4 is provided on the inner bottom surface of the drying box 3, and a plurality of rotating shafts 6 are rotatably connected in the groove 4. A plurality of rollers 7 are fixed to the outer walls of the rotating shafts 6, and the rollers 7 are arranged to support the movement of the bottom plate 8, so that the bottom plate 8 can move smoothly inside the drying box 3.

[0036] Reference Figure 3 and Fig. 9 In order to prevent the odor and hot air in the drying box 3 from escaping to the outside, a plurality of thermal insulation curtains 31 are provided at the openings on both sides of the drying box 3. These thermal insulation curtains 31 are close to each other to form an effective heat insulation and odor isolation barrier to ensure that the heat and odor during the drying process will not leak into the outside environment.

[0037] Through the above design, the assembled aluminum cabinet paint spraying equipment not only realizes the rapid drying and odor treatment of the aluminum cabinet surface, but also improves the accuracy of spraying and the utilization rate of raw materials by optimizing the spraying structure.

[0038] Example 2 refer to Figure 10-12 , based on the improvement of Example 1: two second movable plates 36 are provided in the drying box 3, and the two second movable plates 36 are respectively located on both sides of the bearing platform 9. A plurality of rectangular grooves 37 are provided in the second movable plate 36, and a vertical plate 47 is slidably connected in each rectangular groove 37. The vertical plate 47 is fixed on the top of the base plate 1 to ensure that the second movable plate 36 can slide stably on the base plate 1. A sliding rod 38 is also fixed in the rectangular groove 37, and the sliding rod 38 slides through the vertical plate 47 to provide a guide for the sliding of the second movable plate 36.

[0039] refer to Fig.12 A spring 39 is fixed to one side of the vertical plate 47 near the bearing platform 9, one end of the spring 39 is fixedly connected to the inner wall of one side of the rectangular groove 37, and the spring 39 is sleeved on the outer wall of the sliding rod 38. In this way, when the second movable plate 36 is moved outward by an external force, the spring 39 will be compressed; when the external force disappears, the spring 39 will drive the second movable plate 36 to move back to the middle.

[0040] refer to Fig.12 A plurality of racks 40 are fixed at the bottom of the second movable plate 36, and a plurality of vertical plates 47 on the same side are rotatably connected to a rotating shaft 41 through a base plate at a side away from the carrier 9. A plurality of residual gears 42 are fixed to the outer wall of the rotating shaft 41, and these residual gears 42 are intermittently meshed with the racks 40. When the rotating shaft 41 rotates, the residual gears 42 drive the second movable plate 36 to intermittently move outward.

[0041] refer to Fig.12A rubber pad 46 is fixed on one side of the second movable plate 36 close to the bearing platform 9 to increase the contact friction with the aluminum cabinet to ensure that the aluminum cabinet can push the second movable plate 36 to move to both sides. A placement groove 43 is provided on the top of the second movable plate 36, and a lifting plate 44 is slidably connected in the placement groove 43. A grinding belt for grinding water drop-shaped paint is installed on the top of the lifting plate 44 to remove the water drop-shaped paint that may be formed on the bottom of the aluminum cabinet during the drying process.

[0042] refer to Fig.12 The bottom of the lifting plate 44 is rotatably connected to a lead screw 45, and the bottom end thread of the lead screw 45 penetrates the second movable plate 36. By rotating the lead screw 45, the height of the lifting plate 44 can be controlled so that the grinding belt can closely contact the bottom of the aluminum cabinet to ensure the grinding effect.

[0043] refer to Fig.12 , a guiding slope is provided on one side of the second movable plate 36, which is used to enable the aluminum cabinet to smoothly push the second movable plate 36 to move to both sides to make way during the movement. When the bottom plate 8 drives the aluminum cabinet to move into the drying box 3, the cabinet feet of the aluminum cabinet will touch the slope of the second movable plate 36 and push the second movable plate 36 to move outward. Until the aluminum cabinet moves between the two second movable plates 36, at this time, the rotating shaft 41 is driven by the motor to rotate, and the rotating shaft 41 drives the residual gear 42 to rotate. Since the residual gear 42 is intermittently meshed with the rack 40, it will drive the second movable plate 36 to move outward for a distance, and then reset under the action of the spring 39. In this way, the second movable plate 36 can be driven to move back and forth through the continuous rotation of the motor.

[0044] Specifically, during the reciprocating movement, the grinding belt on the top of the lifting plate 44 will contact the bottom of the aluminum cabinet to remove the water drop-shaped paint formed during the drying process, thereby ensuring the aesthetics of the aluminum cabinet.

[0045] The above implementation method ensures that the assembled aluminum cabinet paint spraying equipment can effectively remove the water drop paint on the bottom of the aluminum cabinet during the drying process, thereby improving the quality and aesthetics of the product. At the same time, the implementation method has the advantages of simple structure, convenient operation, significant effect, etc., and has high practicality and promotion value.

[0046] A method for using an assembled aluminum cabinet paint spraying device, comprising the following steps: S1. The bottom plate 8 and the aluminum cabinet thereon are conveyed to the spray box 2 by the conveyor chain 5. When the aluminum cabinet moves to the bottom of the top plate 10, the water pump 18 injects the paint in the storage box 48 into the first liquid storage pipe 17, and the paint is evenly sprayed on the two cabinet surfaces of the aluminum cabinet through the nozzle 15. Then, the screw 16 is driven by the motor to rotate, and the screw 16 drives the first movable plate 14 to move, so that the cabinet surface can be evenly sprayed with paint through the cooperation of the first movable plate 14 and the nozzle 15; S2. When spraying the other two cabinet surfaces and the top cabinet surface of the aluminum cabinet, the motor arranged in the bottom plate 8 drives the bearing platform 9 to rotate, driving the aluminum cabinet to rotate 180°, and at the same time, the motor drives the bidirectional screw 11 to rotate, and the bidirectional screw 11 drives the two frames 13 to move to both sides to prevent the screw 16 from touching the aluminum cabinet. In addition, when the bearing platform 9 rotates, the inclined surface at one end of the semicircular ring 24 cooperates with the insertion rod 26 to drive the insertion rod 26 and the first touch piece 28 to move outward, and the first touch piece 28 touches the second touch piece 30. At this time, the electromagnetic nozzle 21 is energized, and the electromagnetic nozzle 21 sprays the top cabinet surface of the aluminum cabinet until the insertion rod 26 loses the resistance of the semicircular ring 24 and resets. When the bearing platform 9 rotates, the screw 16 drives the first movable plate 14 to move, and the nozzle 15 can apply paint to the other two cabinet surfaces of the aluminum cabinet; S3. After the coating is finished, the conveyor chain 5 conveys the aluminum cabinet to the drying box 3, and the outside air is sucked into the drying box 3 by the first fan 32. The heating plate arranged on the inner wall of the drying box 3 heats the air in the drying box 3, and then the first fan 32 and the second fan 33 blow air to the cabinet surface of the aluminum cabinet to dry the cabinet surface, and the air pump 34 sucks the air containing the paint odor in the drying box 3 into the water tank 35, and the salt water in the water tank 35 absorbs harmful substances such as formaldehyde in the paint to avoid air pollution; S4. When the bottom plate 8 drives the aluminum cabinet to move into the drying box 3, the cabinet feet of the aluminum cabinet touch the inclined surface of the second movable plate 36, and push the second movable plate 36 to move outward until the aluminum cabinet moves between the two second movable plates 36. The rotating shaft 41 is driven by the motor to rotate, and the rotating shaft 41 drives the residual gear 42 to rotate. The residual gear 42 is intermittently engaged with the rack 40, driving the second movable plate 36 to move outward and reset under the action of the spring 39. Therefore, the second movable plate 36 can be driven to reciprocate. The grinding belt on the top of the lifting plate 44 can remove the water drop-shaped paint at the bottom of the aluminum cabinet during the drying process to ensure the aesthetics of the aluminum cabinet.

[0047] However, as is well known to those skilled in the art, the working principles and wiring methods of the water pump 18, electromagnetic nozzle 21, first fan 32, second fan 33 and vacuum pump 34 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.
