Description

Technical Field

[0001] This application relates to the technical field of coating equipment, and in particular to a spray gun holder for a coating equipment. Background Technology

[0002] Coating is a crucial step in surface manufacturing. Rust prevention, corrosion resistance, aesthetics, and mitigating inherent material defects are all important aspects of coating quality, which are vital to overall product quality. A product's appearance not only reflects its protective and decorative properties but also significantly contributes to its value. Coating equipment is a critical component of the entire coating process.

[0003] A utility model patent with Chinese patent authorization announcement number CN222093756U discloses an automatic spray gun holder for a coating equipment. The device includes a housing, blocks fixed to both ends of two horizontal bars that fit against the inner side of the housing, vertical bars fixed to the bottom of two first electric sliders, second electric sliders slidably engaged with the outer sides of the two vertical bars, a spray gun mounted on one side of each second electric slider, and a third electric slider fixed to the bottom of the lower block via a connecting rod. A sliding rod is slidably engaged with the inner wall of the third electric slider, and a bracket mounted on the inner side of the housing is fixed to the back of the sliding rod. This utility model relates to the field of spray gun holder technology. Through the cooperation of the bracket, sliding rod, and third electric slider, it achieves automatic adjustment of the spray gun's position in three directions, allowing control of the distance between the spray gun and the workpiece. This solves the problem that existing holders can only adjust the up, down, left, and right positions, and cannot adjust the spraying distance according to the workpiece position, thus affecting the final spraying effect.

[0004] The solution also has the following problems: The device uses the cooperation between the bracket, the slide bar and the third electric slider to realize the automatic adjustment of the spray gun position in three directions and to control the distance between the spray gun and the workpiece. However, the above solution still has some problems. For example, the spray gun set by the device can only spray the workpiece in parallel. However, for some irregular workpieces (such as structures with inclined surfaces or grooves), it is difficult to ensure the best spraying angle between the nozzle and the workpiece surface by simply shifting the position. This limits the angle when spraying irregular workpieces. In addition, the clamping of the limiting plate is achieved by the elastic deformation of the spring through the spring. However, the spring may become fatigued and its elasticity may decrease after long-term use, causing the nozzle to loosen.

[0005] Therefore, in order to solve the above problems, this application provides a nozzle adjustment holder for a coating equipment. Utility Model Content

[0006] To address the problem that for some irregularly shaped workpieces (such as those with inclined surfaces or grooves), it is difficult to guarantee the optimal spraying angle between the nozzle and the workpiece surface by simply shifting the position, thus limiting the spraying angle of irregularly shaped workpieces, this application provides a nozzle adjustment holder for a coating equipment.

[0007] This application provides a spray nozzle adjustment holder for a coating equipment, comprising two vertical rods and two electrically operated sliders. Each of the two vertical rods has an electrically operated slider slidably mounted on it. A flipping device is provided between the two electrically operated sliders. The flipping device includes:

A mounting plate is fixedly connected to one side of the mounting base. A nozzle is provided on the side of the mounting plate away from the mounting base. A bevel gear is fixedly connected to the rotating shaft. A bevel gear is rotatably connected to one side wall of the fixed frame. The bevel gear and the bevel gear mesh.

[0009] Limiting devices are provided on both sides of the fixing frame;

[0010] The top and bottom of the two electric sliders are provided with drive components.

[0011] The limiting device is equipped with a second driving component.

[0012] Preferably, a rotating shaft two is rotatably mounted on the side of the fixed frame near the bevel gear one, one end of the rotating shaft two is fixedly connected to the bevel gear one, and a motor three is fixedly connected to one side of the fixed frame, the output end of the motor three is fixedly connected to the rotating shaft two.

[0013] Preferably, an electric slider is fixedly connected to the top and bottom of each of the two vertical rods.

[0014] Preferably, a crossbar is provided between two adjacent electric sliders, and blocks are fixedly connected to both ends of the two crossbars.

[0015] Preferably, the bottom of the two vertical rods is provided with a housing, and the two blocks are slidably engaged with the inner side of the housing.

[0016] Preferably, the limiting device includes:

[0017] Both of the two electric sliders have through grooves on both sides of their top and bottom. Sliders are slidably installed in each of the multiple grooves. Each of the two electric sliders has a limit plate on the side near the fixed frame. The multiple sliders are fixedly connected to the limit plate by a connecting frame. Each of the two limit plates has through grooves on the side near the fixed frame. Two limit plates are slidably installed in each of the two grooves. The top and bottom of the two limit plates are in contact with the top and bottom of the fixed frame.

[0018] Preferably, the driving component one includes:

[0019] Two screws are rotatably connected to the two upper sliding grooves. Both screws pass through the slider and are threaded to the slider. The two screws rotate coaxially and have opposite thread directions. A motor is fixedly connected to one side of the electric slider. The output end of the motor is fixedly connected to the screws via a coupling.

[0020] Preferably, the second driving component includes:

[0021] Both of the two slide grooves are rotatably connected to a two-way lead screw, both of the two two-way lead screws pass through two limiting plates, both of the two two-way lead screws are threaded to the two limiting plates, and both of the tops of the two limiting plates are fixedly connected to a motor, both of the two motors are fixedly connected to the top of the two-way lead screws through a coupling.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. In this utility model, by setting a second rotating shaft to drive a first bevel gear to rotate, the first bevel gear to drive a second bevel gear to rotate, the second bevel gear to drive the first rotating shaft and the mounting base to rotate up and down, the mounting base to drive the mounting plate to rotate up and down, and the mounting plate to drive the spray head to rotate up and down, so that the spray head can spray the inclined surface and groove of the irregular workpiece. The spraying angle can be flexibly adjusted to ensure that the spray head can be aligned with the normal direction of the inclined surface or penetrate into the groove, avoiding spraying dead angles, greatly improving the uniformity and integrity of the coating. Moreover, the bevel gear transmission has the characteristics of precise transmission ratio and stable power transmission, which can accurately control the rotation angle of the spray head.

[0024] 2. In this utility model, two screws rotate to drive two sliders to move closer together. The two sliders drive two connecting frames to move closer together, and the connecting frames drive limiting plates one to move closer together. This fixes and limits the two limiting plates on both sides of a pair of fixed frames. Then, a bidirectional lead screw drives two limiting plates two to move closer together. The two limiting plates two simultaneously limit the top and bottom of both sides of the fixed frame. This simultaneously limits the sides, top, and bottom of the fixed frame, offsetting external forces (such as vibrations during processing and the weight of the workpiece) from multiple directions. This ensures that the fixed frame does not loosen or shift during operation, making it particularly suitable for high-precision processing or spraying scenarios. It ensures a reliable fixing effect, reduces deformation of the fixed frame caused by uneven force (such as slight bending of the metal fixed frame), and protects the integrity of the workpiece and equipment.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0033] Example 1, such as Figure 1-5 As shown, this utility model provides a spray nozzle adjustment holder for a coating equipment, including a vertical rod 5, an electric slider 6, a flipping device, a limiting device, a drive assembly 1, and a drive assembly 2. Two vertical rods 5 are provided, and electric sliders 6 are slidably mounted on both vertical rods 5. The flipping device includes: a fixed frame 16 between the two electric sliders 6; a rotating shaft 22 rotatably connected to the fixed frame 16; a mounting base 21 fixedly connected to the rotating shaft 22; a mounting plate 20 fixedly connected to one side of the mounting base 21; a spray nozzle 7 mounted on the side of the mounting plate 20 away from the mounting base 21; a bevel gear 19 fixedly connected to the rotating shaft 22; and the fixed frame 1... A bevel gear 23 is rotatably connected to one side wall of the 6, and the bevel gear 23 meshes with the bevel gear 19. A rotating shaft 24 is rotatably installed on the side of the fixed frame 16 near the bevel gear 23. One end of the rotating shaft 24 is fixedly connected to the bevel gear 23. A motor 15 is fixedly connected to one side of the fixed frame 16. The output end of the motor 15 is fixedly connected to the rotating shaft 24. Electric sliders 4 are fixedly connected to the top and bottom of the two vertical rods 5. A crossbar 3 is set between two adjacent electric sliders 4. Blocks 2 are fixedly connected to both ends of the two crossbars 3. A housing 1 is set at the bottom of the two vertical rods 5. The two blocks 2 slide in cooperation with the inner side of the housing 1.

[0034] In this embodiment, the nozzle 7 can be moved by the block 2, the electric slider 4, and the electric slider 6. At the same time, the motor 15 can be started. The motor 15 drives the rotating shaft 24 to rotate, the rotating shaft 24 drives the bevel gear 23 to rotate, the bevel gear 23 drives the bevel gear 19 to rotate, the bevel gear 19 drives the rotating shaft 22 and the mounting base 21 to rotate up and down, the mounting base 21 drives the mounting plate 20 to rotate up and down, and the mounting plate 20 drives the nozzle 7 to rotate up and down, so that the nozzle 7 can spray the inclined surface and groove of the irregular workpiece.

[0035] Example 2, as Figure 1-5 As shown, the limiting device includes: two electric sliders 2 6 with through grooves on both sides of the top and bottom, sliders 8 slidably installed in multiple grooves 1, limiting plates 1 13 provided on the side of the two electric sliders 2 6 near the fixed frame 16, multiple sliders 8 and limiting plates 1 13 fixedly connected by connecting frame 12, two limiting plates 1 13 with through grooves on the side of the two limiting plates 1 13 near the fixed frame 16, two limiting plates 2 17 slidably installed in the two grooves 2, the top and bottom of the two limiting plates 2 17 contacting the top and bottom of the fixed frame 16;

[0036] The drive assembly includes: two upper slides rotatably connected to screws 10, both screws 10 passing through sliders 8 and threadedly connected to sliders 8; the two screws 10 rotate coaxially with opposite thread directions; a motor 11 is fixedly connected to one side of an electric slider 6, the output end of which is fixedly connected to the screws 10 via a coupling; multiple slides 1 each have fixed limit rods 9, all passing through sliders 8 and slidingly engaged with sliders 8; the threads between the screws 10 and sliders 8 are self-locking, the self-locking condition depending on the thread helix angle, friction coefficient, and load. The self-locking condition can be calculated using the following formula: self-locking condition = friction coefficient × tan(helix angle) ≥ 1. When this condition is met, the threaded connection is self-locking. The above is all prior art; however, in practical applications, the corresponding self-locking angle can be set according to the friction coefficient of the material, which will not be elaborated further here.

[0037] The second drive assembly includes: two bidirectional lead screws 18 rotatably connected within two sliding grooves; both bidirectional lead screws 18 passing through two limiting plates 17; both bidirectional lead screws 18 threadedly connected to the two limiting plates 17; and motors 14 fixedly connected to the tops of the two limiting plates 13. The two motors 14 are fixedly connected to the tops of the bidirectional lead screws 18 via couplings. The threads between the bidirectional lead screws 18 and the limiting plates 17 are self-locking. The self-locking condition depends on the thread helix angle, the coefficient of friction, and the load applied. The self-locking condition can be calculated using the following formula: Self-locking condition = Coefficient of friction × tan(helix angle) ≥ 1. When this condition is met, the threaded connection is self-locking. The above is all prior art. In practical applications, the corresponding self-locking angle can be set according to the friction coefficient of the material, which will not be elaborated further here.

[0038] In this embodiment, the fixing frame 16 is placed between two limiting plates 13. The motor 11 is started, which drives the two screws 10 to rotate. The two screws 10 drive the two sliders 8 to move closer to each other. The two sliders 8 drive the two connecting frames 12 to move closer to each other. The two connecting frames 12 drive the limiting plates 13 to move closer to each other. The two limiting plates 13 drive the other sliders 8 to slide on the limiting rods 9, so that the two limiting plates 13 move synchronously. This allows the two limiting plates 13 to fix and limit the two sides of the fixing frame 16. Then, the motor 2 is started, which drives the bidirectional lead screw 18 to rotate. The bidirectional lead screw 18 drives the two limiting plates 17 to move closer to each other. The two limiting plates 17 simultaneously limit the top and bottom of the two sides of the fixing frame 16, thus ensuring a reliable fixing effect.

[0039] Working principle: In use, the fixing frame 16 is placed between the two limiting plates 13. The motor 11 is started, driving the two screws 10 to rotate. The two screws 10 drive two sliders 8 to move closer together, which in turn drives the two connecting frames 12 to move closer together. The two connecting frames 12 then drive the limiting plates 13 to move closer together, and the two limiting plates 13 drive the other sliders 8 to slide on the limiting rods 9. This causes the two limiting plates 13 to move synchronously, thus fixing and limiting the two sides of the fixing frame 16. Then, the motor 14 is started, driving the bidirectional lead screw 18 to rotate. The bidirectional lead screw 18 drives the two limiting plates 17 to move closer together, thus fixing and limiting the two sides of the fixing frame 16. Plate 2 17 synchronously limits the top and bottom of both sides of the fixing frame 16, thereby ensuring a reliable fixing effect. Then, the nozzle 7 can be moved by the block 2, electric slider 1 4, and electric slider 2 6. At the same time, the motor 3 15 can be started. The motor 3 15 drives the rotating shaft 24 to rotate, the rotating shaft 24 drives the bevel gear 1 23 to rotate, the bevel gear 1 23 drives the bevel gear 2 19 to rotate, the bevel gear 2 19 drives the rotating shaft 1 22 and the mounting base 21 to rotate up and down, the mounting base 21 drives the mounting plate 20 to rotate up and down, and the mounting plate 20 drives the nozzle 7 to rotate up and down, so that the nozzle 7 can spray the inclined surface and groove of the irregular workpiece.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
