Description

Technical Field

[0001] This utility model relates to the technical field of butterfly valve spraying equipment, and in particular to a spraying device for butterfly valve production. Background Technology

[0002] Butterfly valves, as a type of simple regulating valve, are widely used for the on / off control of low-pressure pipeline media. In the production process of butterfly valves, surface spraying is of utmost importance. This not only enhances the corrosion resistance of the butterfly valve and extends its service life, but also improves its aesthetics. In the manufacturing process of butterfly valves, the valve body castings are first inspected and tested. After that, they are processed and polished. Then, an epoxy spraying treatment is used to apply an epoxy coating to the surface of the butterfly valve.

[0003] For example, Chinese patent CN220803959U discloses a painting device for butterfly valve production, including a collection cabinet, a spraying box fixedly connected to the top of the collection cabinet, a spraying mechanism on the top of the spraying box, several equidistant air inlets on the left side of the spraying box, a dustproof net fixedly connected inside the air inlets, a defogging mechanism on the top right side of the spraying box, a cabinet door rotatably connected to the front of the spraying box, and a clamping and rotating mechanism at the bottom inside the collection cabinet.

[0004] Existing butterfly valve spraying equipment typically clamps the butterfly valve during the spraying process, but this prevents the valve from rotating effectively, resulting in uneven spraying, especially on the sides of the valve, which affects the overall spraying quality. To address these issues, a new spraying device for butterfly valve production is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art, and to propose a spraying device for butterfly valve production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spraying device for butterfly valve production, comprising a spraying mechanism and a clamping mechanism installed on the top of the spraying mechanism. The clamping mechanism includes a fixed plate, a motor, a drive gear, a second bevel gear, an electric push rod, and two fixed rods. The output end of the motor is fixedly connected to the top of the drive gear. An arc-shaped frame is welded to the bottom of the drive gear, and a connecting frame is welded to one end of the arc-shaped frame. A driven gear is rotatably connected to the top of the connecting frame. The outer edge of the drive gear meshes with the outer edge of the driven gear. A first bevel gear is welded to the bottom of the driven gear through the connecting frame. The second bevel gear is rotatably installed at one bottom end of the arc-shaped frame, and the electric push rod is fixedly installed at the other bottom end of the arc-shaped frame. The outer edge of the second bevel gear meshes with the outer edge of the first bevel gear. One fixed rod is welded to one end of the second bevel gear, and the other fixed rod is rotatably installed at the output end of the electric push rod. A clamping plate is welded to one end of both fixed rods.

[0007] Preferably, the clamping plate has a cavity inside, and a clamping rod is slidably installed on the inner wall of the cavity.

[0008] Preferably, one end of the clamping rod is connected to one end of the cavity by a spring, and the other end of the clamping rod extends to the outside of the clamping plate, and multiple protrusions are welded in a ring array on the outside of the clamping plate.

[0009] Preferably, the motor is fixedly mounted on the top of the fixed plate, and the spraying mechanism includes a base and a storage tank.

[0010] Preferably, a baffle is welded to the top of the base, and the bottom of the fixing plate is welded to the top of the baffle.

[0011] Preferably, one end of the storage tank is fixedly connected to a conveying pipe, and a spraying end is fixedly installed on the top of the base, with one end of the conveying pipe connected to the spraying end.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by placing the butterfly valve between two clamping plates, the electric push rod drives one of the fixing rods and the clamping plate to move until the two clamping plates clamp the butterfly valve. Multiple protrusions can enhance the clamping firmness of the clamping plates on the butterfly valve, and the rod-shaped clamping rod can always be inserted into the middle hole of the butterfly valve under the elastic force of the spring, which can stably fix the butterfly valve in the suspended state at the bottom of the arc frame, thus ensuring uniform spraying.

[0014] 2. In this utility model, by setting a clamping mechanism, the motor drives the drive gear to rotate, thereby causing the butterfly valve to rotate in the horizontal direction. The drive gear drives the driven gear and the first bevel gear to rotate, thereby driving the second bevel gear and the clamped butterfly valve to rotate. Thus, the butterfly valve can rotate in the horizontal direction while also rotating on its own axis. The spraying end sprays the butterfly valve above until the entire surface of the butterfly valve is sprayed, so that all surfaces of the butterfly valve can be evenly sprayed, avoiding the problem of uneven spraying caused by the butterfly valve's inability to rotate on its own axis, and improving the spraying quality of the butterfly valve.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. 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.

[0022] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a spraying device for butterfly valve production, including a spraying mechanism 1 and a clamping mechanism 2 installed on the top of the spraying mechanism 1. The clamping mechanism 2 includes a fixed plate 21, a motor 22, a drive gear 23, a second bevel gear 27, an electric push rod 28, and two fixed rods 29. The output end of the motor 22 is fixedly connected to the top of the drive gear 23. An arc-shaped frame 24 is welded to the bottom of the drive gear 23, and a connecting frame 215 is welded to one end of the arc-shaped frame 24. A driven gear 25 is rotatably connected to the top of the connecting frame 215. The outer edge of the drive gear 23 meshes with the outer edge of the driven gear 25. A first bevel gear 26 is welded to the bottom of the driven gear 25 through the connecting frame 215. The second bevel gear 27 is rotatably installed at one end of the bottom of the arc-shaped frame 24. The electric push rod 28 is fixedly installed at the bottom of the other end of the arc frame 24. The outer edge of the second bevel gear 27 meshes with the outer edge of the first bevel gear 26. One of the fixing rods 29 is welded to one end of the second bevel gear 27, and the other fixing rod 29 is rotatably installed at the output end of the electric push rod 28. A clamping plate 210 is welded to one end of both fixing rods 29. A cavity 211 is opened inside the clamping plate 210, and a clamping rod 212 is slidably installed on the inner wall of the cavity 211. One end of the clamping rod 212 is connected to one end of the cavity 211 by a spring 214, and the other end of the clamping rod 212 extends to the outside of the clamping plate 210. Multiple protrusions 213 are welded in a ring array on the outside of the clamping plate 210. The motor 22 is fixedly installed on the top of the fixing plate 21.

[0023] The specific settings and functions of this embodiment are described in detail below: When the device sprays the butterfly valve, it first places the butterfly valve between two clamping plates 210. The electric push rod 28 drives one of the fixed rods 29 and the clamping plate 210 to move until the two clamping plates 210 clamp the butterfly valve. Multiple protrusions 213 can enhance the clamping firmness of the clamping plate 210 on the butterfly valve, and the rod-shaped clamping rod 212 can always be inserted into the middle hole of the butterfly valve under the elastic force of the spring 214, which can stably fix the butterfly valve in the suspended state at the bottom of the arc frame 24, thus ensuring uniform spraying.

[0024] After the butterfly valve is fixed in place, the paint pump and motor 22 are started. The motor 22 drives the drive gear 23 and the arc frame 24 to rotate, thereby causing the butterfly valve at the bottom of the arc frame 24 to rotate horizontally (revolve). The drive gear 23 drives the driven gear 25 and the first bevel gear 26 to rotate, thereby driving the second bevel gear 27, the fixing rod 29, and the clamped butterfly valve to rotate. This allows the butterfly valve to rotate horizontally and rotate on its own axis. At the same time, the paint pump delivers the paint in the storage tank 13 to the spraying end 15 through the delivery pipe 14, thereby spraying the butterfly valve above until the entire surface of the butterfly valve is sprayed. This ensures that all surfaces of the butterfly valve can be sprayed evenly, avoiding the problem of uneven spraying caused by the butterfly valve's inability to rotate on its own axis, and improving the spraying quality of the butterfly valve.

[0025] Example 2: Figure 1 and Figure 3 As shown, the spraying mechanism 1 includes a base 11 and a storage tank 13. A baffle 12 is welded to the top of the base 11, and the bottom of the fixing plate 21 is welded to the top of the baffle 12. A conveying pipe 14 is fixedly connected to one end of the storage tank 13. A spraying end head 15 is fixedly installed on the top of the base 11, and one end of the conveying pipe 14 is connected to the spraying end head 15.

[0026] The overall effect of this embodiment is as follows: after the butterfly valve is fixed, the paint pump is started, and the paint pump delivers the paint in the storage tank 13 to the spraying end 15 through the delivery pipe 14, thereby spraying the butterfly valve above until the entire surface of the butterfly valve is sprayed. During the spraying process, the baffle 12 on the top of the base 11 can block the paint during the spraying process, preventing most of the paint from drifting away randomly. After the spraying work is completed, the motor 22, paint pump and other equipment are turned off, and the residual paint on the base 11 is cleaned to prevent the paint from drying and clogging the spraying end 15. The wear of each component is checked regularly, and severely worn components are replaced in time to ensure the normal operation of the device.

[0027] The operating method and working principle of this device are as follows: When spraying a butterfly valve, the butterfly valve is first placed between two clamping plates 210. The electric push rod 28 drives one of the fixing rods 29 and the clamping plate 210 to move until the two clamping plates 210 clamp the butterfly valve. Under the elastic force of the spring 214, the clamping rod 212 can always be inserted into the middle hole of the butterfly valve, which can stably fix the butterfly valve in a suspended state at the bottom of the arc frame 24, ensuring uniform spraying. After the butterfly valve is fixed, the paint pump and motor 22 are started. The motor 22 drives the drive gear 2 The rotation of the arc-shaped frame 24 causes the butterfly valve at the bottom of the arc-shaped frame 24 to rotate horizontally (revolution). The driving gear 23 drives the driven gear 25 to rotate, which in turn drives the bevel gear 27 and the clamped butterfly valve to rotate. This allows the butterfly valve to rotate horizontally while also rotating on its own axis. At the same time, the paint pump delivers the paint from the storage tank 13 to the spraying end 15 through the delivery pipe 14, thereby spraying the butterfly valve above. This ensures that all surfaces of the butterfly valve receive uniform spraying, avoiding uneven spraying caused by the butterfly valve's inability to rotate on its own axis, and improving the spraying quality of the butterfly valve.

[0028] 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 present utility model.
