Description

Technical Field

[0001] This utility model relates to the field of spray coating technology, specifically to a swing-type automatic spray coating device for spray coating. Background Technology

[0002] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets by pressure or centrifugal force and apply them to the surface of the object. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivatives of the above basic spraying methods.

[0003] In the prior art, such as the precision electronic processing swing-type automatic spraying device with announcement number CN217796862U, there is a device body, a swing component and a fixing component, and it also includes an adsorption component for collecting and purifying the irritating odor generated during the spraying process. The adsorption component includes an exhaust fan, a pipe and an adsorption pad. The exhaust fan is fixedly connected to the side panel, and the pipe is fixedly connected to the exhaust fan and the placement platform.

[0004] In the above, a clean spraying effect was basically achieved by the combination of the swing component and the exhaust fan. However, after reading the technical solution, it was found that when the spray gun swings up and down, the spraying trajectory of the paint becomes a parabola. This trajectory makes it impossible for the paint to cover the workpiece surface evenly, resulting in poor spraying quality and excessive waste of paint on the outer side, leading to excessive paint consumption. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a swing-type automatic spraying device for spraying, which can effectively solve the problem that the parabolic trajectory in the existing technology makes it impossible for the paint to be evenly covered on the surface of the workpiece.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a swing-type automatic spraying device for spraying processing, including a workpiece, a fixing bolt adapted to be installed on the side of the workpiece, and the fixing bolt is cooperated with a rotating spraying component and an area-increasing component.

[0008] The circular spraying assembly includes a drive source, the output end of which is fixedly connected to a straight shaft. A stabilizing disc is fitted at the bottom of the straight shaft, and a circular rotating disk is fitted on the outer surface of the straight shaft. A spur gear is rotatably connected to the end face of the circular rotating disk. The teeth of the spur gear mesh with an internal gear disc, and the spur gear is engaged with a paint supply component via its own key shaft.

[0009] Furthermore, the paint supply component includes a accumulator ring, which is fixedly sleeved with the key shaft. A booster pump is connected to the side of the accumulator ring, and a paint tube is inserted into the bottom of the accumulator ring.

[0010] Furthermore, the number of spur gears is several, and the several spur gears are distributed in a circular array.

[0011] Furthermore, the area-increasing component includes a straight cylinder fixedly connected to the outer wall of the straight shaft. The inner cavity of the straight cylinder is provided with a tension spring. A pull rod is snapped onto the end face of the tension spring. A ball rod is slidably connected to the side of the pull rod. A limit block is provided on the outer surface of the pull rod. A limit slot is opened on the side of the straight cylinder. The groove surface of the limit slot is slidably connected to the limit block.

[0012] Furthermore, the outer surface of the cue is rotatably fitted with an extension plate, the extension plate being triangular in shape, and the surface of the extension plate having a material leakage opening.

[0013] Furthermore, a baffle plate is fixedly connected to the top of the drive source, and a base is snapped onto the side of the baffle plate, with the base fitting into the bottom of the workpiece.

[0014] Furthermore, the paint tube section is composed of multiple curved tubes distributed outwards, and the bottom of the paint tube section is separated from the expansion plate.

[0015] Furthermore, the displacement range of the extension plate is greater than that of the circumferential surface of the spur gear, and the inner shape of the material leakage opening is circular.

[0016] Beneficial effects

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] 1. By meshing the spur gear with the internal gear disc, the rotation of the spur gear drives the paint supply component to rotate, achieving the effect of circulating spraying of the paint supply component and solving the problem of uneven spraying on the workpiece surface. By connecting the booster pump with the accumulator ring, the spray material can continuously enter the inner cavity of the accumulator ring, which is conducive to the sustained spraying of paint. At the same time, the paint tube is inserted and installed at the bottom of the accumulator ring, which allows the paint to be evenly sprayed onto the workpiece surface through the paint tube, avoiding the accumulation of spray material on the workpiece surface.

[0019] Second, an extension plate is rotated and installed on the surface of the cue stick. After the spray material impacts the extension plate, the extension plate rotates along the surface of the cue stick and is finally sprayed out through the discharge hole. This optimizes the problem of the spray material sticking together during the falling process and also expands the spraying area of ​​the spray material, thereby improving the spraying quality of the workpiece.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] See attached document Figure 1-5 An automatic oscillating spraying device for spraying processing includes a workpiece 1, a fixing bolt 3 adapted to be installed on the side of the workpiece 1, and a rotating spraying component 4 and an area-increasing component 5 in cooperation with the fixing bolt 3.

[0030] The rotating spraying assembly 4 includes a drive source 41, the output end of which is fixedly connected to a straight shaft 42. A stabilizing disk 43 is fitted at the bottom of the straight shaft 42. A rotating disk 45 is fitted on the outer surface of the straight shaft 42. A spur gear 46 is rotatably connected to the end face of the rotating disk 45. The teeth of the spur gear 46 mesh with an internal gear disk 47, and the spur gear 46 is engaged with a paint supply component 48 via its own key shaft.

[0031] The mounting bolt 3 on the side of the workpiece 1 ensures its stable placement and allows the drive source 41 to connect with the straight shaft 42, so that the power output of the drive source 41 is directly transmitted to the straight shaft 42, facilitating the synchronous rotation of the ring turntable 45, meeting the circumferential painting requirements of the paint supply part 48, and allowing the spur gear 46 to mesh with the internal gear disk 47, so that the rotation of the spur gear 46 will drive the paint supply part 48 to rotate, achieving the effect of cyclic spraying of the paint supply part 48 and solving the problem of uneven spraying on the surface of the workpiece 1.

[0032] The paint supply component 48 includes a material storage ring 481, which is fixedly sleeved with the key shaft. A booster pump 482 is connected to the side of the material storage ring 481, and a paint tube 483 is inserted into the bottom of the material storage ring 481. There are several spur gears 46, and the distribution of the several spur gears 46 is in a ring array.

[0033] By connecting the booster pump 482 to the accumulator ring 481, the spray material can continuously enter the inner cavity of the accumulator ring 481, which is beneficial for the sustained spraying of the paint. At the same time, by inserting and installing the paint tube 483 at the bottom of the accumulator ring 481, the paint can be evenly sprayed onto the surface of the workpiece 1 through the paint tube 483, avoiding the accumulation of spray material on the surface of the workpiece 1.

[0034] The area-enhancing component 5 includes a straight cylinder 51 fixedly connected to the outer wall of the straight shaft 42. A tension spring 52 is provided in the inner cavity of the straight cylinder 51. A pull rod 53 is snapped onto the end face of the tension spring 52. A ball rod 55 is slidably connected to the side of the pull rod 53. A limit block 54 is provided on the outer surface of the pull rod 53. A limit slot 511 is opened on the side of the straight cylinder 51. The groove surface of the limit slot 511 is slidably connected to the limit block 54.

[0035] By setting a tension spring 52 inside the straight cylinder 51, the straight cylinder 51 is affected by the centrifugal force of the straight shaft 42, and the tension spring 52 can push the pull rod 53 to move, thereby allowing the cue stick 55 to slide. A limiting block 54 is set on the outer surface of the pull rod 53, and the limiting block 54 is slidably connected to the limiting slot 511, making the displacement of the pull rod 53 more stable and preventing wobbling.

[0036] An extension plate 56 is rotatably fitted on the outer surface of the cue stick 55. The extension plate 56 is triangular in shape and has a material leakage opening 561 on its surface.

[0037] An extension plate 56 is rotatably mounted on the surface of the cue stick 55, so that after the spray material impacts the extension plate 56, the extension plate 56 rotates along the surface of the cue stick 55 and is finally sprayed out through the discharge hole 561. This optimizes the problem of the spray material sticking together during the falling process and also expands the spraying area of ​​the spray material, thereby improving the spraying quality of the workpiece 1.

[0038] A baffle plate 44 is fixedly connected to the top of the drive source 41, and a base 2 is snapped onto the side of the baffle plate 44. The base 2 is fitted and connected to the bottom of the workpiece 1.

[0039] By fixing a baffle plate 44 on the surface of the drive source 41, the vibration of the drive source 41 during operation can be reduced, thereby reducing air transmission and avoiding affecting the natural drop of the spray material. At the same time, a base 2 is installed at the bottom of the workpiece 1 to keep the position of the workpiece 1 fixed, which indirectly ensures the spraying quality.

[0040] The paint tube section 483 is composed of multiple curved tubes that are distributed outwards, and there is a distance between the bottom of the paint tube section 483 and the extension plate 56.

[0041] By combining multiple curved tubes, the spraying range is significantly expanded, saving spraying time for workpiece 1, and also improving the problem of excessive material waste.

[0042] The displacement range of the extension plate 56 is greater than that of the circumferential surface of the spur gear 46, and the inner shape of the material leakage opening 561 is circular.

[0043] The extension plate 56 is moved further, allowing more spray material to flow out along its surface, directly increasing the spraying area. At the same time, the circular design of the discharge opening 561 reduces spray material residue and improves utilization.

[0044] Working principle: First, place the workpiece 1 on the upper surface of the base 2 and fix it with the fixing bolt 3. Then start the drive source 41. The drive source 41 drives the straight shaft 42 to rotate at high speed, which further makes the spur gear 46 move synchronously in a circular motion. Since the internal gear disk 47 and the spur gear 46 are meshed, under the action of the internal gear disk 47, the trajectory of the spur gear 46 is the center of the circle and it can rotate on its own, creating the basic conditions for uniform spraying.

[0045] At the same time, the external controller is turned on, which causes the booster pump 482 to start automatically. The booster pump 482 continuously sprays the paint into the storage ring 481. The storage ring 481 further allows the paint to enter the inner cavity of the paint tube 483, so that the paint falls on the surface of the workpiece 1. Under the effect of circumferential rotation, the spraying amount is more uniform and the spraying area is wider.

[0046] The centrifugal force generated by the high-speed rotation of the straight shaft 42 causes the tension spring 52 to stretch along the outer side of the straight shaft 42. Under the action of the tension spring 52, the pull rod 53 pushes the ball rod 55 to slide in a straight line. During the falling process, the paint first hits the surface of the extension plate 56, causing the extension plate 56 to rotate around the ball rod 55. A part of the paint moves along the surface of the extension plate 56, eventually filling the area near the straight shaft 42 with paint, thus expanding the effective spraying area of ​​the workpiece 1. Another part of the paint passes through the discharge opening 561, preventing paint accumulation on the surface of the workpiece 1.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
