Description

Technical Field

[0001] The present invention relates to the technical field of aluminum powder spraying equipment, and specifically to a powder spraying equipment for aluminum production. Background Art

[0002] Aluminum profiles, as one of the metal materials widely used in modern industry, are known for their light weight, high strength, corrosion resistance, easy processing, and good electrical and thermal conductivity. It is widely used in many fields such as building curtain walls, transportation, electronic equipment, furniture manufacturing, and aerospace. The surface treatment of aluminum profiles, especially spraying treatment, can not only improve the aesthetics of products, but also enhance their weather resistance, wear resistance, and corrosion resistance, thereby extending the service life. In the spraying treatment of aluminum profiles, electrostatic spraying dominates in aluminum profile spraying due to its high efficiency and uniformity.

[0003] During the use of existing powder spraying equipment, deficiencies have gradually emerged, mainly manifested in the following aspects: First, the metal powder adhesion rate is low. Specifically, existing metal powder spraying equipment is mainly divided into two structural forms: vertical and horizontal. In vertical spraying equipment, aluminum materials need to be vertically suspended, and operators need to hold a spray gun to spray the suspended aluminum materials. To avoid mutual shielding of the spraying paths between adjacent aluminum materials and ensure spraying uniformity, a large suspension distance must be maintained. Similarly, although horizontal spraying equipment can drive the aluminum materials to rotate through a rotating mechanism to achieve all-round spraying, to prevent mutual collision and interference of the aluminum materials during rotation, sufficient spacing must also be reserved between adjacent aluminum materials. This necessary spacing setting results in some metal powder not adhering to the surface of the aluminum materials during spraying but directly spraying out through the gaps between the aluminum materials. Therefore, the metal powder adhesion rate is low, causing waste of metal powder.

[0004] Second, the workpiece loading and unloading process is cumbersome. Specifically, when using horizontal powder spraying equipment for aluminum profile spraying, due to process requirements, the aluminum materials must be accurately clamped inside the equipment. Therefore, when fixing the aluminum materials, operators need to lean into the equipment to complete the accurate positioning and clamping of the workpieces. This operation method makes the entire workpiece loading and unloading process cumbersome and time-consuming. At the same time, the limited internal space of the equipment also poses potential risks to the safety of operators.

[0005] In summary, it is obvious that there are inconveniences and defects in the actual use of the existing technology, so it is necessary to improve it. Summary of the Invention

[0006] Aiming at the defects in the prior art, the technical problem to be solved by the present invention is to provide a powder spraying device for aluminum production. When spraying aluminum, the adjacent aluminum materials are arranged without gaps. This tight layout completely solves the problem of powder escape caused by the necessary spacing in traditional spraying devices, greatly improves the adhesion rate of metal powder, and reduces the waste of metal powder. When replacing the aluminum materials, the operator can quickly complete the picking, placing and positioning of the aluminum materials by operating outside, which simplifies the feeding and discharging process, reduces potential safety hazards, and improves the practicality of the device.

[0007] To solve the above problems, the present invention provides the following technical solutions: A powder spraying device for aluminum production, including a spraying box with an open top. A box door is hinged at the open end of the spraying box. Inside the spraying box, a fixed U-shaped plate fixedly arranged and several horizontally movable sliding U-shaped plates are horizontally arranged in parallel. Several slots are provided at the end of the sliding U-shaped plate. Several inserting rods are fixedly arranged at the ends of the fixed U-shaped plate and the sliding U-shaped plate. One end of the inserting rod extends into the slot of the adjacent sliding U-shaped plate and is provided with a detachably arranged limiting ring. Horizontally sliding sliding L-shaped plates and swingable swing L-shaped plates are arranged on the tops of the fixed U-shaped plate and the sliding U-shaped plate. A positioning plate is rotatably arranged at the end of the swing L-shaped plate along the horizontal line. Several first avoidance grooves are provided at the opposite ends of the positioning plate. Several second avoidance grooves are provided at the top and bottom of the positioning plate. The first avoidance grooves and the second avoidance grooves are arranged front and back. Guide wheels rotatably arranged are provided in the first avoidance grooves and the second avoidance grooves. Part of the area of the guide wheels is located outside the positioning plate. A spraying component for spraying aluminum is provided at the bottom of the box door.

[0008] As an optimized scheme, the spraying component includes a moving plate. Two sliding plates are horizontally slidably arranged at the bottom of the box door. The moving plate is detachably connected to the two sliding plates. Several powder spray guns are fixedly inserted on the moving plate. The powder spray guns are connected to an external powder supply system through powder conveying pipes.

[0009] As an optimized scheme, a side support shaft and a lower support shaft are respectively fixedly arranged at the end and the bottom of the swing L-shaped plate. Several detachably arranged V-shaped tracks are arranged on the tops of the fixed U-shaped plate and the sliding U-shaped plate. Several V-shaped rollers rotatably connected to the lower support shaft are sleeved on the lower support shaft. The V-shaped rollers are in rolling connection with the V-shaped tracks. A lifting plate rotatably connected to the side support shaft is sleeved on the side support shaft. The lifting plate is vertically lifted and lowered.

[0010] As an optimized solution, rectangular grooves are provided through the tops of the fixed U-shaped plate and the sliding U-shaped plate, and control telescopic cylinders are fixedly provided at the bottoms of the fixed U-shaped plate and the sliding U-shaped plate. The telescopic ends of the control telescopic cylinders pass through the rectangular grooves and are fixedly connected to the lifting plate.

[0011] As an optimized solution, the two ends of the fixed U-shaped plate are detachably connected to the opposite inner walls of the spraying box correspondingly. A number of horizontally slidable sliders are provided on the opposite inner walls of the spraying box, and the two ends of the sliding U-shaped plate are detachably connected to the sliders.

[0012] As an optimized solution, a number of hydraulic telescopic cylinders are fixedly provided at the inner bottom of the spraying box, and the telescopic ends of the hydraulic telescopic cylinders are fixedly connected to the outermost sliding U-shaped plate.

[0013] As an optimized solution, driving telescopic cylinders are fixedly provided at the tops of the fixed U-shaped plate and the sliding U-shaped plate, and the telescopic ends of the driving telescopic cylinders are fixedly connected to the sliding L-shaped plate.

[0014] As an optimized solution, a number of detachably arranged fixed shafts are inserted through the ends and the bottom of the positioning plate. The fixed shafts pass through the first avoidance groove or the second avoidance groove, and the guide wheels are rotatably sleeved on the fixed shafts.

[0015] As an optimized solution, a steering motor is fixedly provided at the end of the swinging L-shaped plate. The output shaft of the steering motor passes through the swinging L-shaped plate and is fixedly connected to the positioning plate.

[0016] As an optimized solution, a number of mounting plates are fixedly provided at the bottom of the box door. Two threaded lead screws are provided below the box door. The two ends of the threaded lead screws are rotatably connected to the two mounting plates correspondingly. The threaded lead screws pass through the sliding plate and are threadedly connected to the sliding plate. Driving motors are fixedly provided at the ends of the two mounting plates, and the output shafts of the driving motors are fixedly connected to the threaded lead screws.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. When spraying aluminum materials, the driving motor drives the moving plate and the powder spray gun to move horizontally. The external powder supply system transports metal powder through the powder delivery pipe to the powder spray gun and sprays it out. The sprayed metal powder adheres to the top surface of the aluminum material. After the top surface of the aluminum material is sprayed, the hydraulic telescopic cylinder drives the outermost sliding U-shaped plate to move horizontally. The insertion rod and the sliding U-shaped plate move relatively. When the limit ring abuts against the inner wall of the slot, it drives the adjacent sliding U-shaped plate to move horizontally until all the limit rings abut against the inner wall of the slot. At this time, gaps are generated between the fixed U-shaped plate and the sliding U-shaped plate and between adjacent two sliding U-shaped plates. The driving telescopic cylinder drives the sliding L-shaped plate to slide horizontally, thereby releasing the restriction on one end of the aluminum material. Then, the orientation-adjusting motor drives the positioning plate and the aluminum material to rotate 90° (the rotation directions of adjacent two aluminum materials are opposite to prevent the unsprayed surface of the aluminum material from contacting the sprayed surface, resulting in a reduction in the amount of metal powder on the sprayed surface). The unsprayed surface of the aluminum material rotates to the upper side. The sliding L-shaped plate resets and restricts the aluminum material. The hydraulic telescopic cylinder drives the outermost sliding U-shaped plate to reset, thereby resetting all the sliding U-shaped plates. At this time, the adjacent aluminum materials are arranged without gaps. Repeat the above process to spray the four end faces of the aluminum material in sequence. When this equipment sprays aluminum materials, the adjacent aluminum materials are arranged without gaps. This tight layout completely solves the problem of powder escape caused by the necessary spacing of traditional spraying equipment, greatly improves the adhesion rate of metal powder, and reduces the waste of metal powder; 2. After the aluminum material is sprayed, the hydraulic telescopic cylinder drives the outermost sliding U-shaped plate to move horizontally to the limit position. At this time, the sprayed aluminum materials are arranged at intervals. The sliding L-shaped plate slides horizontally to release the restriction on the aluminum material. The control telescopic cylinder drives the lifting plate to move downward. The V-shaped rollers roll along the V-shaped track. The swinging L-shaped plate drives the positioning plate and the aluminum material to swing upward (as shown in Figure 11 ), and the staff can quickly remove the aluminum material. When inserting the aluminum material, the staff holds the aluminum material and inserts one end of it into the positioning plate. The guide wheels contact the inner wall of the aluminum material and guide the aluminum material until the aluminum material abuts against the swinging L-shaped plate. Then, the swinging L-shaped plate and the sliding L-shaped plate reset successively. Thus, the loading of the aluminum material is completed. When this equipment replaces the aluminum material, the operator can quickly complete the picking, placing, and positioning of the aluminum material by operating outside, simplifies the material picking and placing process, reduces safety hazards, and improves the practicality of the equipment; 3. The front and rear arranged guide wheels can not only play a role in positioning and supporting the aluminum material compared with positioning components such as positioning inserts, but also facilitate the insertion and picking of the aluminum material, further improving the practicality of the equipment.

[0024] A side support shaft 25 and a lower support shaft 23 are respectively fixedly provided at the end and the bottom of the swing L-shaped plate 18. Several detachable V-shaped tracks 21 are provided at the tops of the fixed U-shaped plate 6 and the sliding U-shaped plates 5. Several V-shaped rollers 22 rotatably connected thereto are sleeved on the lower support shaft 23. The V-shaped rollers 22 are in rolling connection with the V-shaped tracks 21. A lifting plate 24 rotatably connected thereto is sleeved on the side support shaft 25. The lifting plate 24 is vertically lifted and lowered.

[0025] Rectangular slots 19 are provided through the tops of the fixed U-shaped plate 6 and the sliding U-shaped plates 5. Control telescopic cylinders 20 are fixedly provided at the bottoms of the fixed U-shaped plate 6 and the sliding U-shaped plates 5. The telescopic ends of the control telescopic cylinders 20 pass through the rectangular slots 19 and are fixedly connected to the lifting plate 24.

[0026] The two ends of the fixed U-shaped plate 6 are detachably connected to the opposite inner walls of the spraying box 1 respectively. Several horizontally slidable sliders 7 are provided on the opposite inner walls of the spraying box 1. The two ends of the sliding U-shaped plates 5 are detachably connected to the sliders 7 respectively.

[0027] Several hydraulic telescopic cylinders 34 are fixedly provided at the bottom inside the spraying box 1. The telescopic ends of the hydraulic telescopic cylinders 34 are fixedly connected to the outermost sliding U-shaped plate 5.

[0028] A driving telescopic cylinder 9 is fixedly arranged at the top of both the fixed U-shaped plate 6 and the sliding U-shaped plate 5, and the telescopic end of the driving telescopic cylinder 9 is fixedly connected with the sliding L-shaped plate 8.

[0029] A plurality of detachably arranged fixed shafts 26 are inserted through the end and bottom of the positioning plate 15. The fixed shafts 26 penetrate through the first avoidance groove 13 or the second avoidance groove 16, and the guiding wheels 14 are rotatably sleeved on the fixed shafts 26.

[0030] A steering motor 17 is fixedly arranged at the end of the swinging L-shaped plate 18. The output shaft of the steering motor 17 passes through the swinging L-shaped plate 18 and is fixedly connected with the positioning plate 15.

[0031] A plurality of mounting plates 30 are fixedly arranged at the bottom of the box door 4. Two threaded lead screws 32 are arranged below the box door 4. The two ends of the threaded lead screws 32 are correspondingly rotatably connected with the two mounting plates 30. The threaded lead screws 32 penetrate through the sliding plate 31 and are threadedly connected with the sliding plate 31. A driving motor 33 is fixedly arranged at the end of the two mounting plates 30, and the output shaft of the driving motor 33 is fixedly connected with the threaded lead screw 32.

[0032] The working principle of this device is as follows: When spraying the aluminum material 2, the driving motor 33 drives the moving plate 29 and the powder spray gun 27 to move horizontally. The external powder supply system transports the metal powder through the powder delivery pipe 28 to the powder spray gun 27 and sprays it out from the powder spray gun 27. The sprayed metal powder adheres to the top surface of the aluminum material 2. After the top surface of the aluminum material 2 is sprayed, the hydraulic telescopic cylinder 34 drives the outermost sliding U-shaped plate 5 to move horizontally. The insertion rod 12 and the sliding U-shaped plate 5 move relatively. When the limiting ring 11 abuts against the inner wall of the slot 10, it drives the adjacent sliding U-shaped plate 5 to move horizontally until all the limiting rings 11 abut against the inner wall of the slot 10. At this time, a gap is generated between the fixed U-shaped plate 6 and the sliding U-shaped plate 5 and between two adjacent sliding U-shaped plates 5. The driving telescopic cylinder 9 drives the sliding L-shaped plate 8 to slide horizontally, thereby releasing the restriction on one end of the aluminum material 2. Then, the steering motor 17 drives the positioning plate 15 and the aluminum material 2 to rotate 90° (the rotation directions of two adjacent aluminum materials 2 are opposite to prevent the unsprayed surface of the aluminum material 2 from contacting the sprayed surface, resulting in a reduction in the amount of metal powder on the sprayed surface). The unsprayed surface of the aluminum material 2 rotates to the upper side. The sliding L-shaped plate 8 resets and restricts the aluminum material 2. The hydraulic telescopic cylinder 34 drives the outermost sliding U-shaped plate 5 to reset, thereby causing all the sliding U-shaped plates 5 to reset. At this time, the adjacent aluminum materials 2 are arranged without gaps. Repeat the above process to spray the four end faces of the aluminum material 2 in sequence. When this equipment sprays the aluminum material 2, the adjacent aluminum materials 2 are arranged without gaps. This tight layout completely solves the problem of powder escape caused by the necessary spacing of traditional spraying equipment, greatly improves the adhesion rate of the metal powder, and reduces the waste of the metal powder; After the aluminum material 2 is sprayed, the hydraulic telescopic cylinder 34 drives the outermost sliding U-shaped plate 5 to move horizontally to the limit position. At this time, the sprayed aluminum materials 2 are arranged at intervals. The sliding L-shaped plate 8 slides horizontally to release the restriction on the aluminum material 2. The telescopic cylinder 20 is controlled to drive the lifting plate 24 to move downward. The V-shaped roller 22 rolls along the V-shaped track 21, and the swinging L-shaped plate 18 drives the positioning plate 15 and the aluminum material 2 to swing upward (as Figure 11 shown). The staff can quickly remove the aluminum material 2. When inserting the aluminum material 2, the staff holds the aluminum material 2 and inserts one end of it into the positioning plate 15. The guide wheel 14 contacts the inner wall of the aluminum material 2 and guides the aluminum material 2 until the aluminum material 2 abuts against the swinging L-shaped plate 18. Then the swinging L-shaped plate 18 and the sliding L-shaped plate 8 are reset successively. Thus, the loading of the aluminum material 2 is completed. When replacing the aluminum material 2 of this equipment, the operator can quickly complete the taking, placing and positioning of the aluminum material 2 through external operation, which simplifies the material taking and placing process, reduces potential safety hazards, and improves the practicability of the equipment; The front and rear arranged guide wheels 14 can not only play a role in positioning and supporting the aluminum material 2 compared with positioning components such as positioning insertion plates, but also facilitate the insertion and taking of the aluminum material 2, further improving the practicability of the equipment.
