Description

Technical Field

[0001] This invention relates to the field of powder coating equipment technology, and in particular to a powder coating device and method for producing basketball hoops. Background Technology

[0002] The powder coating equipment for basketball hoop production is an integrated electrostatic powder coating system. It is mainly used for the corrosion protection and decoration of large metal components such as the main column, backboard frame, and base of the basketball hoop. When the powder coating equipment is working, it uses a high-voltage electrostatic field to make the powder coating powder negatively charged and the grounded basketball hoop workpiece positively charged. The powder evenly covers the surface of the workpiece under the electrostatic adsorption effect, and then is cured at high temperature to form a dense, corrosion-resistant, and impact-resistant coating.

[0003] Existing powder coating equipment sprays powder onto the workpiece through a spray gun. When spraying large flat surfaces, a nozzle with a more diffused spray effect is selected to improve powder coating efficiency. When spraying corners, a nozzle with a more concentrated spray effect is selected to ensure that the powder coating can penetrate into the corners. Therefore, existing powder coating equipment requires frequent nozzle changes to meet powder coating needs, which makes powder coating inconvenient and requires the preparation of various different nozzles to meet powder coating needs, resulting in high powder coating costs. Summary of the Invention

[0006] More preferably, all the first adjusting members and the two second adjusting members are circumferentially equally spaced, and the plane on which the two second adjusting members are located divides all the first adjusting members into two groups of equal number. The first adjusting member is composed of a first inclined part and a first horizontal part, and the second adjusting member is composed of a second inclined part, a second horizontal part and a third inclined part.

[0007] More preferably, the variable nozzle is provided with first spray holes that are evenly distributed in the circumferential direction, the adjusting rod is provided with second spray holes, the second spray holes are connected to the corresponding first spray holes, the spray pipe is fixedly connected to a motor, and the output shaft of the motor is driven by the rotating pipe through a gear ring.

[0008] More preferably, the adjusting rod is slidably connected to a sealing element, which is used to block the corresponding second spray hole.

[0009] More preferably, the sealing member is fixedly connected to a spring telescopic rod, and a return spring is provided between the fixed part of the spring telescopic rod and the corresponding adjusting rod. Both the first adjusting member and the second adjusting member are fixedly connected to a pressing member. The telescopic end of the spring telescopic rod is rotatably connected to a roller. The pressing member is used to push the adjacent roller. The adjusting rod is fixedly connected to a blocking block, and the blocking block is used to limit the adjacent sealing member.

[0010] More preferably, the extrusion member has a first extrusion part and a second extrusion part, and when the second horizontal part contacts the adjacent transmission rod, the plane where the first extrusion part is located is perpendicular to the axis of the adjacent adjustment rod, and the plane where the second extrusion part is located is perpendicular to the axis of the adjacent spring telescopic rod.

[0011] More preferably, the adjusting rod is hinged to a baffle, and the baffles, which are evenly distributed around the circumference, work together to block the variable nozzle.

[0012] More preferably, the baffle is wound with an elastic rope, the adjusting rod is fixedly connected to a guide post, the elastic rope passes around the corresponding guide post and is fixedly connected to the corresponding sealing member, and an elastic sheet is fixedly connected between the baffle and the corresponding adjusting rod.

[0013] More preferably, the elastic coefficient of the elastic rope is greater than that of the elastic sheet.

[0014] A method of using a powder coating device for basketball hoop production, based on the aforementioned powder coating device for basketball hoop production, specifically includes the following steps: S1: Activate the integrated component and aim the variable nozzle at the basketball hoop. The integrated component causes the powder coating powder to enter the spray pipe from the powder tank through the pipe, then through the rotating pipe to the variable nozzle, and finally sprayed onto the basketball hoop by the variable nozzle. S2: When powder coating a large area of ​​flat surface, the telescopic end of the electric push rod is shortened and drives the sliding frame. The sliding frame drives the adjusting rod to rotate. The adjusting rods distributed at equal intervals in the circumference expand the variable nozzle, thereby increasing the range of powder coating powder sprayed from the variable nozzle. S3: When powder coating dead corners, the extension end of the electric push rod is extended and drives the sliding frame. The sliding frame drives the circumferentially evenly distributed adjustment rods to reduce the opening of the variable nozzle, thereby concentrating the powder coating powder and allowing the powder coating powder to penetrate into the dead corner. S4: As the telescopic end of the control electric push rod continues to extend, the third inclined part squeezes the transmission rod, and the transmission rod drives the adjacent adjusting rod to open the variable nozzle so that the powder coating powder is sprayed out from the variable nozzle in a fan shape. S5: When the telescopic end of the electric push rod drives the extrusion component to move, the extrusion component drives the adjacent sealing component to move, thereby releasing the seal on the adjacent second nozzle. S6: When the sealing component moves, the sealing component drives the adjacent baffle to rotate, thereby causing the baffles that are evenly distributed in the circumferential direction to block the variable nozzle. Then, the output shaft of the motor drives the variable nozzle and the adjusting rod to rotate, so that the powder coating powder is sprayed out through the first spray hole and the second spray hole. S7: After powder coating is completed, turn off the integrated components.

[0015] The beneficial effects of adopting the above solution are as follows: The present invention sets up a variable nozzle with a changeable shape and uses circumferentially evenly distributed adjusting rods as the skeleton of the variable nozzle. By changing the state of the adjusting rods, the shape and size of the variable nozzle opening can be changed, thereby meeting the needs of different powder coating.

[0016] By setting a first spray hole and a second spray hole in the variable nozzle and adjusting rod, the powder coating powder is sprayed out circumferentially. The motor drives the rotating tube to rotate, causing the powder coating powder to be sprayed out in a rotating manner. This adds another powder coating method to the variable nozzle, so as to uniformly powder coat the inner wall of the tubular part.

[0017] By blocking the variable nozzle with baffles evenly distributed around the circumference, the powder coating powder will not continue to be sprayed out from the variable nozzle, but will be sprayed out entirely from the second nozzle. This is to avoid the opening of the variable nozzle diverting the powder coating powder, which would result in an insufficient amount of powder being sprayed out from the second nozzle.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] A powder coating device for basketball hoop production, such as Figures 1-5As shown, the device includes an integrated component 1, on which a powder tank 2 is mounted. The powder tank 2 holds powder coating powder and is connected to a spray pipe 3. The integrated component 1 contains a control terminal, an electrostatic generator, and an air supply device. The electrostatic generator charges the powder coating powder, and the air supply device allows the powder coating powder from the powder tank 2 to enter the spray pipe 3. Since these are all existing devices, they will not be described in detail here. A rotating tube 4 is rotatably connected to the front of the spray pipe 3, and a variable nozzle 5 is fixedly connected to the rotating tube 4. The variable nozzle 5 is made of an elastic material and is used to change the opening shape of the variable nozzle 5 to adapt to different powder coating requirements. Specific materials can be selected such as fluororubber, which is wear-resistant and high-temperature resistant. The rotating pipe 4 has six circumferentially spaced adjusting rods 6 hinged to its front side. The adjusting rods 6 are fixedly connected to the variable nozzle 5. The nozzle 3 is slidably connected to a sliding frame 7, which can slide back and forth along the nozzle 3. The nozzle 3 is fixedly connected to an electric push rod 8, the telescopic end of which is fixedly connected to the sliding frame 7. The front side of the sliding frame 7 is rotatably connected to a rotating ring 9, which is fixedly connected to four first adjusting members 101 and two second adjusting members 102. The adjusting rods 6 are fixedly connected to a transmission rod 11. The first adjusting members 101 and the second adjusting members 102 respectively press the corresponding transmission rod 11 to adjust the state of the adjusting rod 6, thereby changing the shape of the opening of the variable nozzle 5. All the first adjusting members 101 and the two second adjusting members 102 are circumferentially spaced, and the plane where the two second adjusting members 102 are located divides all the first adjusting members 101 into two equal groups of upper and lower parts. The first adjusting member 101 is composed of a first inclined part 1011 and a first horizontal part 1012, and the second adjusting member 102 is composed of a second inclined part 1021, a second horizontal part 1022 and a third inclined part 1023. When the transmission rods 11 on the left and right sides come into contact with the third inclined part 1023, the front of the adjusting rods 6 on the left and right sides expands outward, while the four adjusting rods 6 on the upper and lower sides remain in their original state, thereby making the opening of the variable nozzle 5 flat.

[0023] When using this device to powder coat a basketball hoop, first move the device to the work site and start it. Then, the worker holds the spray nozzle 3 to powder coat the basketball hoop. The powder coating powder enters the spray nozzle 3 from the powder tank 2 through the pipe, then goes through the rotating pipe 4 to the variable nozzle 5, and finally is sprayed onto the basketball hoop by the variable nozzle 5. When powder coating a large flat area, the telescopic end of the electric push rod 8 is shortened, which drives the sliding frame 7 to move backward. The sliding frame 7 drives the rotating ring 9 to move, and the rotating ring 9 drives the first adjusting member 101 and the second adjusting member 102 to move. The first inclined part 1011 and the second inclined part 1021 respectively press the corresponding transmission rod 11. The transmission rod 11 drives the adjacent adjusting rod 6 to rotate. The six adjusting rods 6 will... The variable nozzle 5 is expanded, thereby increasing the range of powder coating powder sprayed from the variable nozzle 5 to achieve a rapid powder coating effect on flat surfaces. When powder coating dead corners, the telescopic end of the electric push rod 8 is extended and drives the sliding frame 7 to move forward. The sliding frame 7 drives the six adjusting rods 6 to narrow the opening of the variable nozzle 5, thereby concentrating the powder coating powder and allowing it to penetrate deep into the dead corners to ensure the powder coating effect. When the telescopic end of the electric push rod 8 continues to extend, the third inclined part 1023 squeezes the corresponding transmission rod 11, causing the adjusting rods 6 on the left and right sides to expand the variable nozzle 5. At this time, the opening of the variable nozzle 5 becomes flat, so that the powder coating powder is sprayed out of the variable nozzle 5 in a fan shape to meet different powder coating needs.

[0024] Example 2

[0025] Based on Example 1, such as Figure 4 and Figure 5 As shown, the variable nozzle 5 is provided with circumferentially evenly distributed first spray holes 501, and the adjusting rod 6 is provided with second spray holes 601. The second spray holes 601 are connected to the corresponding first spray holes 501, so that the powder coating can be sprayed out from the first spray holes 501 and the second spray holes 601, thereby providing more diverse spraying methods for this device. The spray pipe 3 is fixedly connected to the motor 301, and the output shaft of the motor 301 is driven by the rotating pipe 4 through a gear ring. The adjusting rod 6 is slidably connected to the sealing member 12, which is used to seal the corresponding second spray hole 601, so that the second spray hole 601 will not leak when the powder coating is sprayed out from the variable nozzle 5.

[0026] like Figure 4 and Figure 5As shown, the sealing member 12 is fixedly connected to a spring telescopic rod 13. A return spring 14 is provided between the fixed part of the spring telescopic rod 13 and the corresponding adjusting rod 6. Both the first adjusting member 101 and the second adjusting member 102 are fixedly connected to a pressing member 15. The pressing member 15 is used to drive the spring telescopic rod 13 to move, so that the spring telescopic rod 13 drives the sealing member 12 to release the sealing of the adjacent second spray hole 601. The pressing member 15 is misaligned with the corresponding second spray hole 601 to prevent the powder coating from being sprayed out of the second spray hole 601. When the spring telescopic rod 13 is blocked by the extrusion member 15, the extension end of the spring telescopic rod 13 is rotatably connected to the roller 16. The roller 16 is used to reduce the friction between the spring telescopic rod 13 and the extrusion member 15. The adjusting rod 6 is fixedly connected to the blocking block 602. The blocking block 602 is used to limit the adjacent sealing member 12, so that the sealing member 12 will not move due to the extrusion member 15 and the spring telescopic rod 13 during the backward movement of the extrusion member 15, so as to ensure the sealing effect of the sealing member 12 on the second spray hole 601.

[0027] like Figure 5 As shown, the extruder 15 has a first extrusion part 1501 and a second extrusion part 1502. When the second horizontal part 1022 contacts the adjacent transmission rod 11, the plane where the first extrusion part 1501 is located is perpendicular to the axis of the adjacent adjusting rod 6, thereby ensuring that when the extruder 15 moves forward, the spring telescopic rod 13 will only move along the adjusting rod 6 under the pressure of the extruder 15, and will not cause the telescopic end of the spring telescopic rod 13 to retract. The plane where the second extrusion part 1502 is located is perpendicular to the axis of the adjacent spring telescopic rod 13.

[0028] like Figures 4-6 As shown, the adjusting rod 6 is hinged to a baffle 17, which consists of a cylinder and a flat plate. The flat plates of six baffles 17 form a complete plane, thereby blocking the variable nozzle 5. An elastic rope 18 is wound around the cylinder of the baffle 17, and a guide post 19 is fixed to the adjusting rod 6. The guide post 19 is used to change the direction of adjacent elastic ropes 18. The elastic rope 18 passes around the corresponding guide post 19 and is fixed to the corresponding blocking member 12. When the blocking member 12 moves forward, it pulls the elastic rope 18 to make the baffle 17 rotate. An elastic plate 20 is fixed between the baffle 17 and the corresponding adjusting rod 6. The elastic coefficient of the elastic rope 18 is greater than that of the elastic plate 20. When the sealing member 12 moves, the elastic rope 18 pulls the baffle 17 to rotate, and all the baffles 17 together block the variable nozzle 5. After that, the sealing member 12 continues to move, causing the elastic rope 18 to accumulate force. At this time, the rotation of the baffle 17 causes the elastic plate 20 to also accumulate force. However, because the elastic force of the elastic rope 18 is greater than that of the elastic force of the elastic plate 20, the elastic force of the elastic plate 20 is insufficient to pull the baffle 17 back.

[0029] When the transmission rod 11 contacts the corresponding second horizontal part 1022, the first pressing part 1501 contacts the corresponding roller 16. At this time, when the telescopic end of the electric push rod 8 drives the pressing member 15 to move forward, the first pressing part 1501 presses the roller 16. The roller 16 drives the spring telescopic rod 13 to move forward. The spring telescopic rod 13 compresses the adjacent reset spring 14 and drives the adjacent sealing member 12 to move, thereby releasing the blockage of the adjacent second nozzle 601. At this time, the transmission rods 11 on the left and right sides are still in contact with the corresponding second horizontal part 1022 respectively. When the sealing member 12 moves... When the sealing component 12 stretches the adjacent elastic rope 18, the elastic rope 18 drives the adjacent baffle 17 to rotate. When the baffle 17 rotates, it stretches the adjacent elastic sheet 20, thereby blocking the variable nozzle 5 with the two baffles 17. Then the motor 301 starts, and the output shaft of the motor 301 drives the rotating tube 4 to rotate through the gear ring. The rotating tube 4 drives the variable nozzle 5 and the adjusting rod 6 to rotate, so that the powder coating powder is sprayed out through the first spray hole 501 and the second spray hole 601, thereby coating the inner wall of the tubular component and improving the uniformity of the powder coating after spraying, thus improving the uniformity of the powder coating.

[0030] As the first adjusting member 101 and the second adjusting member 102 continue to move forward, the first pressing part 1501 passes over the roller 16. At this time, the roller 16 loses the pressing force of the first pressing part 1501. Under the action of the return spring 14, the spring telescopic rod 13 drives the sealing member 12 to re-seal the second spray hole 601. At the same time, because the sealing member 12 loosens the elastic rope 18, the baffle 17 releases the seal on the variable nozzle 5 under the action of the adjacent elastic plate 20. Thus, the powder coating changes from being sprayed from the second spray hole 601 to being sprayed from the flat variable nozzle 5. When the pressing member 15 moves backward, the second pressing part 1502 presses the roller 16, causing the roller 16 to press the telescopic end of the spring telescopic rod 13. The spring telescopic rod 13 shortens, but does not drive the sealing member 12 to release the seal on the second spray hole 601. That is, when the third inclined part 1023 contacts the adjacent transmission rod 11, the sealing member 12 is in a sealing state.

[0031] Example 3

[0032] Based on Example 2, a method for using a powder coating device for basketball hoop production is described, such as... Figures 1-6 As shown, the powder coating device for producing basketball hoops specifically includes the following steps: S1: Activate the integrated component 1 and aim the variable nozzle 5 at the basketball hoop. The integrated component 1 causes the powder coating powder to enter the spray pipe 3 from the powder tank 2 through the pipe, then through the rotating pipe 4 to the variable nozzle 5, and finally sprayed onto the basketball hoop by the variable nozzle 5. S2: When powder coating a large area of ​​flat surface, the telescopic end of the electric push rod 8 is shortened and drives the sliding frame 7. The sliding frame 7 drives the adjusting rod 6 to rotate. The adjusting rods 6, which are evenly distributed in the circumference, open the variable nozzle 5, thereby increasing the range of powder coating powder sprayed from the variable nozzle 5. S3: When powder coating the dead corner, the telescopic end of the electric push rod 8 is extended and drives the sliding frame 7. The sliding frame 7 drives the circumferentially evenly distributed adjustment rods 6 to reduce the opening of the variable nozzle 5, thereby concentrating the powder coating powder and enabling the powder coating powder to penetrate into the dead corner. S4: As the telescopic end of the control electric push rod 8 continues to extend, the third inclined part 1023 squeezes the transmission rod 11, and the transmission rod 11 drives the adjacent adjusting rod 6 to open the variable nozzle 5 so that the powder coating powder is sprayed out from the variable nozzle 5 in a fan shape. S5: When the telescopic end of the electric push rod 8 drives the extrusion member 15 to move, the extrusion member 15 drives the adjacent sealing member 12 to move, thereby releasing the blockage of the adjacent second nozzle 601. S6: When the sealing member 12 moves, the sealing member 12 drives the adjacent baffle 17 to rotate, so that the baffles 17 distributed at equal intervals in the circumference block the variable nozzle 5. Then the output shaft of the motor 301 drives the variable nozzle 5 and the adjusting rod 6 to rotate, so that the powder coating powder is sprayed out through the first spray hole 501 and the second spray hole 601. S7: After powder coating is completed, turn off integrated component 1.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
