Description

Technical Field

[0001] The invention relates to the technical field of metal spraying, and in particular to a spraying device for metal anti-corrosion processing. Background Art

[0002] Metal materials are widely used in various industrial fields due to their excellent mechanical properties and processing convenience. However, metal materials are easily affected by environmental factors such as humidity, temperature changes and chemical corrosion, which leads to reduced performance and shortened life. In order to extend the service life of metal materials and maintain their performance, the use of anti-corrosion coating is a common and effective method.

[0003] Traditional metal anti-corrosion processing methods mostly use manual spraying or simple mechanical spraying equipment. Although these methods can achieve anti-corrosion treatment of metal surfaces to a certain extent, they still have many shortcomings. For example, manual spraying is difficult to ensure the uniformity and thickness consistency of the coating, and it is easy to cause the coating to be locally too thick or too thin, affecting the anti-corrosion effect and the aesthetics of the material. Traditional mechanical spraying equipment is usually simple in design, with low flexibility and automation, and it is difficult to adapt to the spraying needs of complex or special-shaped metal workpieces.

[0004] In Chinese patent application 202110772215.5, a metal anti-corrosion processing spraying device is disclosed, including a base, a driving mechanism is provided at the upper end of the base, a feeding mechanism is provided at the upper end of the driving mechanism, a spraying mechanism is provided at the lower end of the feeding mechanism, a fixing mechanism is provided at one end of the spraying mechanism, and a shielding mechanism is provided on the lower surface of the spraying mechanism linkage rod. The beneficial effects of the invention are: the rotating rod is driven to rotate by rotating the fixing plate, and the threaded hole is squeezed when the rotating rod rotates, thereby causing the moving block to move, and the moving block drives the conical block to move, and the belt is driven to move when the conical block moves, and at the same time, the rotating plate can be driven to rotate the rotating shaft, and the rotating shaft can drive the belt to reel in, so that the belt inside the horizontal cavity is straightened, and then the belt is driven to block the lower end spray hole, so that the number of spray holes opened can be controlled, and the number of spray holes to be opened is selected according to the specifications of the metal material, thereby preventing excessive opening of the spray holes from causing waste of paint.

[0005] In addition, the existing spraying devices usually have difficulty in achieving accurate positioning and fixing of the workpiece during the spraying process, and are not convenient for directly spraying the upper and lower surfaces of the metal, which not only affects the spraying quality, but also reduces the spraying efficiency.

[0006] Therefore, a novel metal anti-corrosion processing spraying device is needed to solve the above problems. Summary of the invention

[0042] like Figure 1-8 As shown, a metal anti-corrosion processing spraying device of the present invention comprises: a spraying box 1, a cover 11 is arranged on the top of the spraying box 1, a spraying slot 12 is opened on the top of the spraying box 1, a partition plate 13 is fixed in the middle of the spraying slot 12, and metal bodies 14 to be sprayed are placed on both sides of the partition plate 13;

[0043] By placing two metal bodies 14 to be sprayed on both sides of the partition plate 13 in the spray tank 12 and closing the spray tank 12 with the cover 11, harmful substances are prevented from scattering to the outside during spraying to affect the health of workers.

[0044] The support part 2 includes a support plate 21 and a clamping plate 22. One end of the support plate 21 and the clamping plate 22 are both inserted into the inner wall of the spray tank 12 and can move left and right in the horizontal direction. The other end of the support plate 21 extends to the inside of the spray tank 12 for placing the metal body 14. When the support plate 21 is in the supporting position, a position less than half of the bottom of the metal body 14 contacts the support plate 21. The clamping plate 22 is used to clamp the side wall of the metal body 14 after the support plate 21 is separated from the metal body 14.

[0045] The support plate 21 and the clamping plate 22 can move left and right in the horizontal direction, so that the device can adapt to metal bodies 14 of different sizes and shapes. At the same time, the support plate 21 mainly provides a stable platform to support the placement of the metal body 14. Before the spraying process begins, the support plate 21 is first moved to an appropriate position so that the metal body 14 can be placed thereon. The clamping plate 22 is used to clamp the side wall of the metal body 14 during spraying, and the upper and lower surfaces of the metal body 14 can be sprayed directly.

[0046] The spray box 1 is provided with a first support groove 15 inside, one end of the support plate 21 is inserted into the first support groove 15, a first rack 211 is provided on the top of the support plate 21, a second support groove 16 is provided on the top of the first support groove 15, the clamping plate 22 is installed in the second support groove 16, a second rack 221 is provided on the bottom of the clamping plate 22, a plug hole 222 is provided inside the clamping plate 22, a clamping rod 223 is installed inside the plug hole 222, and the clamping rod 22 3, a first spring 224 is sleeved on the first rack 211 and the second rack 221, a rotating shaft 23 is installed between the first rack 211 and the second rack 221, a rotating gear 231 is installed on the rotating shaft 23, and the rotating gear 231 is meshed with the first rack 211 and the second rack 221, wherein when the rotating gear 231 drives the support plate 21 to move into the first support groove 15, the clamping plate 22 pushes the metal body 14 to move close to the partition plate 13 and clamps the metal body 14.

[0047] When spraying, the gear 231 is rotated clockwise to drive the first rack 211 to move to the left, and the second rack 221 to move to the right. At this time, the clamping plate 22 moves to the right and pushes the end of the clamping rod 223 to contact the metal body 14, and squeezes the other side of the metal body 14 to resist the partition plate 13. When the support plate 21 is separated from the metal body 14, the clamping rod 223 compresses the first spring 224 and inserts into the innermost part of the socket 222. The clamping rod 223 and the partition plate 13 clamp the side wall of the metal body 14 to prevent the support plate 21 from blocking the spraying during spraying.

[0048] The spraying part 3 is installed inside the spray box 1, and the spraying part 3 includes a hydraulic cylinder 31 fixed on the top of the cover body 11 and a plurality of piston rods 32 fixed on the bottom of the cover body 11, and a liquid storage chamber 33 installed inside the spray box 1, and a spray pipe 34 is installed on one side of the liquid storage chamber 33. A support frame 110 is installed at the bottom of the spray box 1, and the hydraulic cylinder 31 is fixed on the support frame 110.

[0049] During spraying, the hydraulic cylinder 31 is started to move downward, driving the piston rod 32 and the cover body 11 to move downward. The liquid in the compressed liquid storage chamber 33 of the piston rod 32 moves into the spray pipe 34, and the upper and lower surfaces of the metal body 14 can be sprayed through the spray pipe 34.

[0050] The spray pipe fitting 34 includes a connecting pipe 35 connected to the liquid storage chamber 33, a plurality of first branch pipes 36 installed on the connecting pipe 35, and two second branch pipes 37 connected to the connecting pipe 35. The connecting pipe 35 passes through the partition plate 13. The first branch pipe 36 is located below the metal body 14. The second branch pipe 37 is rotatably installed on the inner wall of the spray tank 12. The second branch pipe 37 is connected to the top of the connecting pipe 35 through a hose 310. The second branch pipe 37 is located directly above the partition plate 13. A plurality of mutually perpendicular third branch pipes 39 are installed on the second branch pipe 37.

[0051] The connecting pipe 35 is the main transmission pipeline between the liquid storage chamber 33 and each branch pipe. It passes through the partition plate 13 to ensure that the paint can flow smoothly from the liquid storage chamber 33 to the branch pipe. The connecting pipe 35 is an inverted T-shaped paint enters the connecting pipe 35 from the liquid storage chamber 33, and enters the first branch pipe 36 through the connecting pipe 35. Multiple first branch pipes 36 evenly spray the bottom surface of the metal body 14. At the same time, two second branch pipes 37 are connected to the top of the connecting pipe 35 through a hose 310 and are rotatably installed on the inner wall of the spray tank 12. Multiple third branch pipes 39 perpendicular to each other are installed on the second branch pipe 37, so that the paint can be more evenly distributed to different sides of the metal body 14. When no spraying is performed, the third branch pipes 39 on the two second branch pipes 37 are parallel to each other in the vertical direction. When spraying, the second branch pipe 37 rotates to drive the third branch pipe 39 and the metal body 14 to be on the same horizontal line. At this time, the third branch pipe 39 can be prevented from blocking the loading and unloading of the metal body 14.

[0052] A lower cover plate 17 is installed at the bottom of the cover body 11, and a third rack 18 is installed at the bottom of the lower cover plate 17. A plurality of first gears 38 are installed on the second branch pipe 37. When the lower cover plate 17 moves downward, the third rack 18 passes between the first gears 38 on two of the second branch pipes 37, driving the second branch pipe 37 to rotate until it is parallel to the metal body 14.

[0053] When the hydraulic cylinder 31 drives the lower cover plate 17 downward, the third rack 18 passes through between the first gears 38 on the two second branch pipes 37, driving the two second branch pipes 37 to rotate 90 degrees in opposite directions, so that the second branch pipes 37 are parallel to the surface of the metal body 14.

[0054] A through hole 19 is provided on the spray box 1, and the piston rod 32 is inserted into the through hole 19. The piston rod 32 is located on both sides of the support plate 21 and the clamping plate 22. A first piston plate 321 is installed on the piston rod 32, and a second piston plate 322 is installed at the bottom of the first piston plate 321. A fourth rack 323 is provided between the first piston plate 321 and the second piston plate 322, and the fourth rack 323 is meshed with the rotating gear 231.

[0055] The piston rod 32 penetrates into the liquid storage chamber 33 from the through hole 19, and meshes with the fourth rack 323 and the rotating gear 231 on the rotating shaft 23. When the piston rod 32 moves downward, it drives the rotating gear 231 to rotate clockwise, the support plate 21 moves to the left, and the clamping plate 22 moves to the right. At the same time, the second piston plate 322 at the bottom of the piston rod 32 compresses the liquid in the liquid storage chamber 33 into the connecting tube 35.

[0056] A blowing cavity 4 is installed above the second supporting groove 16 , a blowing hole 41 is installed on one side of the blowing cavity 4 , and the second piston plate 322 is located in the blowing cavity 4 . When the second piston plate 322 moves up and down, gas is blown from the blowing hole 41 toward the surface of the metal body 14 .

[0057] By setting up the blowing chamber 4, the dust on the surface of the metal body 14 can be blown off. By pressing the first piston plate 321 downward by the piston rod, the generated gas is blown toward the metal body 14 from the air outlet to blow off the dust above it. At the same time, a filter net can be set inside the blowing hole 41. When the piston plate moves upward and resets, the impurity gas after spraying in the spraying slot 12 is adsorbed onto the filter net.

[0058] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
