Description

Technical Field

[0001] The invention relates to the technical field of surface coating, and more particularly to a surface coating device for producing fitness equipment accessories. Background Art

[0002] In the current field of fitness equipment accessories production, surface coating process is a key link to ensure product quality and aesthetics. However, existing surface coating devices face some significant challenges and limitations in practical applications. The primary problem is that operators need to frequently adjust the shape and range of the spray for different accessory shapes, sizes and coating requirements. This adjustment demand stems from the diversity of fitness equipment accessories. From simple handles to complex mechanical parts, each accessory may require a unique coating method. However, existing coating devices often lack a flexible adjustment mechanism, making it difficult to achieve convenient synchronous adjustment of multiple nozzles. This means that operators may need to adjust each nozzle one by one, which is not only time-consuming and labor-intensive, but may also lead to inconsistent adjustments, affecting the uniformity and efficiency of the coating.

[0003] A further problem is that existing nozzle systems usually do not have the ability to adjust the spray shape in both directions. This limitation seriously affects the accuracy and adaptability of the coating process. For example, some accessories may require different spray coverage, or the spray shape needs to be adjusted during the coating process to adapt to the complex contours of the accessories. However, existing technologies cannot meet this demand for flexible adjustment, making it difficult for operators to accurately control the coating process, which may cause some areas to be coated too thick or too thin, affecting the quality and durability of the final product. The lack of this adjustment capability not only reduces production efficiency, but may also increase material waste and even require additional post-processing steps to correct the problem of uneven coating.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a surface coating device for the production of fitness equipment accessories, which has the following beneficial effects:

[0019] 1. The rotating mechanism realizes the precise adjustment of the nozzle angle through the cooperation of the worm and the worm gear. The design of the synchronous sleeve enables multiple nozzles to be adjusted at the same time, which greatly improves the operating efficiency. The independent adjustment function of a single nozzle provides flexibility for special needs.

[0020] 2. The design of the rotating mechanism cleverly realizes the dual movement of fitness equipment accessories. The servo motor drives the active wheel, which in turn drives the rotation of the revolution disk, so that the accessories fixed on the revolution disk can revolve. At the same time, the meshing design of the rotating wheel and the fixed wheel ensures that the accessories can also rotate during the revolution. This dual movement greatly improves the uniformity and coverage of the spraying, ensuring that each accessory surface can be fully and evenly coated, greatly improving the spraying effect and efficiency, while also reducing the generation of spraying dead angles and improving product quality.

[0021] 3. The design of the fixing mechanism solves the problem of fixing the rotating disk and the transmission rod. Through the cooperation of the coaxial sleeve, the friction rod and the slider, a quick and stable connection is achieved. The meshing design of the threaded strip of the tapered sleeve and the spiral groove on the slider allows the operator to adjust the friction force through a simple rotation action, which can not only conveniently fix the fixing rod but also effectively clamp it. At the same time, the design of the embedded strip and the embedded groove ensures the stability of the tapered sleeve during the adjustment process. This design simplifies the operation of replacing the fixing frame, thereby ensuring the stability of the accessories during the spraying process and further improving the spraying quality.

A fitting ring 30 is provided on the adjusting sleeve 13, and a top groove 31 is provided on the adjusting ring.

[0040] Working principle: When it is necessary to spray the surface of fitness equipment accessories, first hang the corresponding fitness equipment accessories on the hook 45. Since the discharge barrel 2 is connected to the external feeding equipment, the paint can be pressed into the discharge barrel 2 by the corresponding pressure, and then the corresponding paint flows into the multiple nozzles 3 respectively. At this time, the paint is atomized through the multiple expansion holes 22 in the adjustment sleeve 13. Since the core of the spray is to convert the liquid into fine droplets, this process is usually achieved by forcing the liquid to pass through a small hole or a specially designed nozzle with high pressure. When the paint passes through the expansion hole 22 at a high speed, due to the sudden decrease in pressure and the shear force of the air, the liquid is split into tiny droplets, so the formed spray can be sprayed onto the accessories of the fitness equipment. At the same time, the corresponding material can be pressed into the multiple adjustment holes 21 through the middle hole 20, and then a spray with a certain pressure will be sprayed out. At this time, the contact between the two sprays will increase the area of ​​the spray sprayed in the expansion hole 22, thereby ensuring the spraying effect.

[0041] When it is necessary to adjust the spraying area, the spraying area can be changed by simply changing the relative positions of the adjusting hole 21 and the expansion hole 22 on the conical head 14. The rotation of the fitting sleeve 5 can drive the rotation of the worm 9. Since the two fitting sleeves 5 are fitted on the lateral tube 4, the worm 9 is in a limited position state, and then the rotation of the fitting sleeve 5 can drive the rotation of the worm 9. Since the worm 9 is threadedly connected to the worm wheel 10, the rotation of the screw 9 will drive the worm wheel 10 to rotate accordingly. Since the worm wheel 10 is slidably connected to the intermediate tube 11, and the telescopic block 16 is slidably connected in the telescopic groove 15, and the double-sided disks 17 are respectively fitted on both sides of the worm wheel 10, the worm wheel 10 will not rotate with the rotation of the intermediate tube 11. Since the middle tube 11 is threadedly connected to the tail tube 12, the relative positions of the middle tube 11 and the tail tube 12 can be adjusted by rotating the middle tube 11. Since the conical head 14 is installed on the middle tube 11, the position of the conical head 14 can be adjusted, thereby changing the relative positions of the adjustment hole 21 and the expansion hole 22. Under the action of the baffle 18 and the tail spring 19, it is ensured that the middle tube 11 can be stably fixed after being adjusted to multiple positions. In addition to adjusting the position of the conical head 14, the position of the adjusting sleeve 13 can also be changed. Since the adjusting sleeve 13 is threadedly connected to the middle ring 23, the double-sided bidirectional springs 24 ensure that the adjusting sleeve 13 can be effectively fixed when it is in multiple positions, thereby completing the adjustment process.

[0042] When multiple worm gears 9 rotate synchronously, since the synchronous sleeves 7 are respectively sleeved on the hexagonal rods 6, the multiple worm gears 9 can be driven to rotate synchronously, thereby ensuring the convenience of adjustment, and when a single nozzle 3 needs to be adjusted, it is only necessary to move the synchronous sleeve 7 in the opposite direction, so that the synchronous sleeve 7 and the hexagonal rod 6 on the corresponding nozzle 3 can be disconnected, and then the adjustment process of the single synchronous sleeve 7 is completed. After the synchronous sleeve 7 is loosened, the return stroke of the synchronous sleeve 7 is guaranteed under the action of the internal spring 8, thereby ensuring the connection between the two hexagonal rods 6.

[0043] When the adjustment of the adjustment sleeve 13 is completed, since the inner strip 28 on the stop sleeve 27 is slidably connected in the follower groove 29, and the other end of the inner strip 28 abuts in the top groove 31, the stable fixation between the adjustment sleeve 13 and the nozzle 3 is guaranteed, thereby ensuring the spraying effect.

[0044] In order to achieve uniform spraying of fitness equipment accessories, a rotating mechanism is added. Please refer to Figure 1 , Figure 2 and Fig.10 The rotating mechanism includes a bearing 32, a servo motor 33, a revolving wheel 34, a driving wheel 35 and a revolving disk 36. One end of the bearing 32 is connected to the chassis 1, and the other end of the bearing 32 is connected to the revolving disk 36. The servo motor 33 is fixedly mounted on the chassis 1, and the driving wheel 35 is mounted on the protruding end of the servo motor 33. The revolving wheel 34 is fixedly mounted on the revolving disk 36, and the driving wheel 35 is meshed on the revolving disk 36. A plurality of fixed cylinders 37 are fixedly arranged on the revolving disk 36. A transmission rod 38 is rotatably provided on each fixed cylinder 37, an insertion rod 39 is provided on the upper end of the transmission rod 38, a self-rotating wheel 40 is provided on the lower end of the transmission rod 38, a fixed wheel 41 is provided on the chassis 1, and multiple self-rotating wheels 40 are respectively engaged with the fixed wheel 41, a tray 42 is provided on the insertion rod 39, a self-rotating disk 43 is fitted on the tray 42, the insertion rod 39 is clamped on the self-rotating disk 43, a fixing frame 44 is provided on the self-rotating disk 43, and a hook 45 is provided on the upper end of the fixing frame 44.

[0045] Working principle: when it is necessary to rotate multiple fitness equipment accessories, first the servo motor 33 can drive the rotation of the driving wheel 35, the driving wheel 35 is meshed on the revolving wheel 34, and the revolving wheel 34 is installed on the revolving disk 36, so it can drive the rotation of the revolving disk 36, and then with the rotation of the revolving disk 36, multiple fixed frames 44 will revolve accordingly, and at this time the self-rotating wheel 40 is meshed on the fixed wheel 41, and the self-rotating wheel 40 is also rotating while revolving. Since the self-rotating wheel 40 is connected to the transmission rod 38, the insertion rod 39 on the transmission rod 38 is clamped on the self-rotating disk 43, thereby ensuring the transmission of power, so that the fixed frame 44 can be ensured to rotate accordingly, and at this time the fitness equipment accessories can not only revolve but also rotate, thereby ensuring a better spraying effect.

[0046] See also Figure 11-13 In order to fix the self-rotating disk 43, a fixing mechanism is added, which includes a coaxial sleeve 46, a friction rod 47, a slider 48, a spring 49 and a friction plate 50. The coaxial sleeve 46 is coaxially mounted on the self-rotating disk 43, and the friction rod 47 is coaxially mounted on the transmission rod 38. A plurality of inclined grooves 51 are equidistantly provided on the side wall of the coaxial sleeve 46, and each inclined groove 51 is respectively slidably connected to the slider 48. A spring 49 is respectively mounted on each slider 48, and a friction plate 50 is mounted on the spring 49. The friction plate 50 abuts against the side wall of the friction rod 47. A tapered sleeve 52 is provided for rotation, and a threaded strip 53 is provided on the inner wall of the tapered sleeve 52. A follower block 54 is provided on each slider 48. A plurality of follower blocks 54 are provided with spiral grooves 55, and a plurality of spiral grooves 55 are respectively engaged with the threaded strip 53. An embedded strip 56 is provided coaxially on the coaxial sleeve 46. An embedded groove 57 is provided on the inner wall of the tapered sleeve 52. The embedded strip 56 is slidably connected in the embedded groove 57. A hexagonal sleeve 58 is provided coaxially on the outer wall of the tapered sleeve 52. A contact ring 59 is provided coaxially on the inner wall of the tapered sleeve 52. The contact ring 59 is sleeved on the coaxial sleeve 46.

[0047] Working principle: When it is necessary to replace different fixing frames 44 according to different fitness equipment accessories, first fit the corresponding rotating disk 43 on the tray 42, and then the friction rod 47 passes through the coaxial sleeve 46. At this time, rotating the hexagonal sleeve 58 can drive the rotation of the cone sleeve 52. Since the embedded strip 56 is rotated and connected in the embedded groove 57, the upper and lower limits of the cone sleeve 52 are guaranteed, and then it can be guaranteed to rotate at the corresponding position. At this time, the threaded strip 53 rotates accordingly. Since the multiple spiral grooves 55 are engaged on the threaded strip 53, they can slide up and down at any time. Then the friction plate 50 expands and moves upward at the same time. At this time, the friction plate 50 fits on the friction rod 47, and then the friction force is provided by the time elastic force of multiple springs 49. At this time, with the rotation, it can not only be fixed but also the friction rod 47 can be pushed upward, thereby ensuring the stable fixation between the rotating disk 43 and the transmission rod 38, thereby completing the fixing process.
