Description

Technical Field

[0001] The invention relates to the technical field of metal equipment spraying, and more specifically, to a metal gradient wear-resistant coating spraying device for fitness equipment processing. Background Art

[0002] Metal gradient wear-resistant coating is a very important coating for fitness equipment. It can effectively protect fitness equipment and extend its service life. Therefore, in the metal fitness equipment manufacturing industry, the metal gradient wear-resistant coating spraying process is a key link. However, the current spraying equipment faces a problem: it is difficult to adapt to the diversified needs of metal fitness equipment. Metal fitness equipment is usually composed of rectangular plates of various sizes, and the existing spraying equipment can often only handle sizes within a limited range and lacks the flexibility to deal with plates of different sizes. This limitation leads to inefficient spraying process and unstable quality.

[0003] This problem of not being able to adjust the spray area according to different sizes has a serious impact on the production efficiency and product quality of metal fitness equipment, specifically: For small size plates, overspray may occur, which not only wastes paint, but may also affect the accuracy and fit of the parts.

[0004] For large-sized panels, spray coverage may be insufficient, affecting the durability and appearance quality of the product.

[0005] Since the spraying area cannot be precisely controlled, operators often need to adjust and repeat the spraying multiple times, which not only increases production time and cost, but may also lead to inconsistent spraying quality due to human operating errors.

An internal thread 24 is provided on the inner wall of the bidirectional sleeve 19, and the internal thread 24 and the internal screw 11 are threadedly connected. The pitch of the external thread 23 is greater than the pitch of the internal thread 24. A plurality of guide grooves 25 are equidistantly provided on the inner wall of the nozzle 6, and a plurality of guide strips 26 are equidistantly provided on the outer wall of the sealing disk 7. The plurality of guide strips 26 are slidably connected in the plurality of guide grooves 25. A reducing ring 27 is coaxially provided on the upper end surface of the sealing disk 7. When the conical groove 12 is fitted on the cone head 10, the uppermost end of the reducing ring 27 is parallel to the upper end surface of the nozzle 6.

[0027] Working principle: When it is necessary to spray the rectangular plates of metal fitness equipment of different sizes, first adjust the position of the transverse plate 5 according to the corresponding size, and the cylinder 34 can drive the movement of the transverse plate 5. Since the transverse plate 5 is installed on the sliding block 38, and the sliding block 38 is slidably connected to the slide rail 37, it can move laterally along the slide rail 37. At the same time, the pressing sleeve 4 slides along the sliding sleeve 3. Since the size of the pressing sleeve 4 is sufficient to cover the adjusted size of the transverse plate 5, the pressing sleeve 4 will continue to press on the right end of the sliding sleeve 3 to ensure that the nozzle 6 at the right end is all within the coverage range of the pressing sleeve 4. Then, as the pressing sleeve 4 moves, the pressing sleeve 4 compresses the sealing disk 7 downward along the reducing ring 27. Since the hexagonal rod 16 is slidably connected to the hexagonal sleeve 17 and the synchronous rod 20 is slidably connected in the synchronous sleeve 21, it can be carried out. Slide up and down, and the spring 18 and multiple synchronous springs 22 will also be compressed accordingly. When the sealing ring and the upper end surface of the nozzle 6 are in a parallel state, the cone head 10 is also pressed in the cone groove 12, so that the multiple spray holes 13 are in a sealed state. At this time, the sealing disk 7 will be inside the pressing sleeve 4, thereby ensuring that the internal nozzle 6 is in a sealed state, so that the number of sprayable nozzles 6 can be changed synchronously when adjusting according to different plate sizes, thereby ensuring that it adapts to the shape of the plate, and then the paint is introduced through the two-way tube 2 and the sliding sleeve 3, and then the paint with a certain pressure enters the nozzle 6. At this time, the nozzle 6 in the open state will spray paint through the spray hole 13, and then the plate is sprayed. In the process, since the spray atomization degree can be adjusted according to the degree of opening of the cone head 10 and the cone groove 12, the spraying effect of the plate used in the production of metal fitness equipment is guaranteed.

[0028] When the degree of atomization needs to be changed, the wrench is first inserted into the hexagonal slot 15, and then the hexagonal slot 15 is rotated, so that the follower sleeve 14 can be driven to rotate accordingly. Since the hexagonal rod 16 is fixedly installed on the follower sleeve 14, and the hexagonal rod 16 is slidably connected in the hexagonal sleeve 17, the hexagonal sleeve 17 and the bidirectional sleeve 19 can be driven to rotate synchronously. Since the inner screw 11 is threadedly connected to the inner thread 24, and the outer sleeve 101 is threadedly connected to the outer thread 23, and the two are reversely threaded, and the pitch of the outer thread 23 is greater than The pitch of the internal thread 24, so the adjustment amount of each rotation of the outer sleeve 101 is the difference between the internal pitch and the external pitch, so it can play the effect of finely adjusting the distance between the cone head 10 and the cone groove 12, and then because there are multiple synchronization springs 22, the elastic force will be significantly greater than that of a single synchronization spring 22, thereby ensuring that the sealing disk 7 can mainly move with the adjustment of the external sleeve 101, and when the gap between the cone head 10 and the cone groove 12 is changed, the atomization degree of the spray can be changed, so the spray degree of the plate can be changed, thereby ensuring the use effect.

[0029] To achieve lateral movement and drive, add a drive mechanism, see Figure 1 to Figure 2and Figure 7 to Figure 8 The driving mechanism includes a servo motor 28, a driving shaft 29, a fixing frame 30, a driving wheel 31 and a transverse roller 32. The servo motor 28 is fixedly installed on the bottom plate 1, and the protruding end of the servo motor 28 is connected to the driving shaft 29. The fixing frame 30 is installed on the bottom plate 1. The driving shaft 29 is rotatably connected to the fixing frame 30. The driving wheel 31 is limitedly rotatably connected to the transverse plate 5. A limiting groove 33 is provided in the driving wheel 31. The inner wall of the limiting groove 33 is rotatably connected to the transverse roller 32. A plurality of transverse rollers 32 are respectively attached to the outer wall of the driving shaft 29. A cylinder 34 is provided on the bottom plate 1. The protruding end of the cylinder 34 is connected to the transverse roller 32. On the longitudinal plate 5, a plurality of receiving wheels 35 are rotatably provided on the transverse plate 5, and a plurality of receiving wheels 35 are respectively meshed with conveyor belts 36, and the conveyor belts 36 are meshed with the driving wheel 31. Two slide rails 37 are provided on the bottom plate 1, and a sliding block 38 is slidably provided on each slide rail 37, and the two sliding blocks 38 are respectively installed on the transverse plate 5. A lateral frame 39 is respectively provided on the transverse plate 5 and the bottom plate 1, and a plurality of rotating shafts 40 are respectively rotatably provided on each lateral frame 39, and a plurality of expansion springs 41 are respectively provided on each rotating shaft 40, and a clamping wheel 42 is provided on the plurality of expansion springs 41, and a shrinking sleeve 43 is respectively provided on each clamping wheel 42.

[0030] Working principle: when the position of the transverse plate 5 is changed by the cylinder 34, since the transverse roller 32 in the limit groove 33 is engaged with the drive shaft 29, it can not only reduce the lateral friction force, but also drive the rotation of the driving wheel 31. Then, as the transverse plate 5 moves, the rectangular plate can be placed between the two conveyor belts 36, and then the shrinkage sleeves 43 on both sides are pressed against the two sides of the plate through the contraction of the transverse plate 5. Since they are pressed on the shrinkage sleeves 43, the expansion springs 41 can provide both lateral clamping force and vertical fixing force, thereby ensuring stable fixation between the plate and the conveyor belt 36. Then, the driving wheel 31 can be driven to rotate under the action of the servo motor 28, and the conveyor belt 36 can be driven by the driving wheel 31, thereby driving the plate through the upper end of multiple nozzles 6, and then the paint sprayed by the nozzles 6 completes the spraying process on the plate.

[0031] See also Figures 9 to 11In order to realize the feeding of paint, a feeding mechanism is added, which includes a one-way tube 44, a feeding tube 45, a clamping rod 46 and a rubber ring 47. The one-way tube 44 is connected and installed on the two-way tube 2. A plurality of clamping holes 48 are opened on the side wall of the one-way tube 44. A clamping rod 46 is slidably connected in each clamping hole 48, and a rubber ring 47 is installed on the side wall of each clamping rod 46. The rubber ring 47 is slidably connected in the clamping hole 48. An annular groove 49 is opened on the side wall of the feeding tube 45, and a plurality of clamping rods 46 respectively abut against the annular groove 49. A lifting sleeve 50 is threadedly provided on the one-way tube 44, and a plurality of anti-slip grooves 51 are equidistantly opened on the side wall of the lifting sleeve 50. A thrust bearing 52 is provided on the lower end surface of the lifting sleeve 50, and a thrust sleeve 53 is coaxially provided on the lower end surface of the thrust bearing 52. A groove 54 is opened on the thrust sleeve 53, and a plurality of clamping rods 46 respectively abut against the groove 54. A plurality of protective springs 55 are provided on the lower end surface of the thrust sleeve 53, and a stop sleeve 56 is coaxially provided on the one-way tube 44. A plurality of protective springs 55 are respectively connected to the stop sleeve 56. A bottom spring 57 is provided on the feed pipe 45, and a one-way disk 58 is provided on the bottom spring 57. A bottom groove 59 is opened on the lower end surface of the one-way tube 44, and the one-way disk 58 abuts against the bottom groove 59. A rubber sleeve 60 is provided on the lower end surface of the feed pipe 45, and the rubber sleeve 60 is connected to the one-way disk 58.

[0032] Working principle: Since the feed pipe 45 is connected to the external feeding equipment, the feed pipe 45 and the one-way pipe 44 need to be sealed. First, the feed pipe 45 is inserted into the one-way pipe 44. At this time, the one-way disk 58 will slide downward until the one-way disk 58 fits in the bottom groove 59, and then the lifting sleeve 50 is rotated. Since the lifting sleeve 50 is threadedly connected to the one-way pipe 44, the lifting sleeve 50 can be pressed downward, and then the thrust of the rotation can be changed into a vertical thrust through the thrust bearing 52, thereby driving The push sleeve 53 slides downward, and at this time, one end of the clamping rod 46 is against the groove 54. The push sleeve 53 slides downward, and the clamping rod 46 can be contracted toward the axis of the one-way tube 44, so that the clamping tube is abutted in the annular groove 49, and then the feed pipe 45 can be driven to slide downward, and then the bottom spring 57 is compressed, thereby providing pressure for the one-way disk 58, ensuring the sealing effect between the one-way disk 58 and the bottom groove 59, and then the paint introduced through the feed pipe 45 ensures the sealed connection with the two-way tube 2.

[0033] When it is necessary to release the seal between the feed pipe 45 and the one-way tube 44, firstly, the lifting sleeve 50 is rotated in the opposite direction to release the interference between the groove 54 and the clamping rod 46, and then the bottom spring 57 provides reverse pressure, and then the clamping rod 46 is adapted to expand outward, and a plurality of protective springs 55 are used to prevent the clamping rod 46 from falling outward, and each clamping rod 46 is provided with a rubber ring 47, which fits on the inner wall of the clamping hole 48, thereby ensuring that the clamping rod 46 has a certain friction force, ensuring that the clamping rod 46 will not move without being subjected to a large force, and preventing it from falling inward, and then the feed pipe 45 can be pulled out to release the connection between the two.

[0034] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here.
