Description

Technical Field

[0001] This utility model relates to the technical field of bar surface spraying equipment, specifically a bar surface spraying equipment. Background Technology

[0002] Bar surface spraying equipment is mainly used for coating the surface of metal bars. Currently, most common bar spraying equipment adopts a structure that combines a fixed spraying station with a single-size conveyor belt. This structure is suitable for continuous spraying operations of standardized bars, and can achieve uniform coverage and rapid curing of the coating. It is widely used in fields such as construction and machinery manufacturing, and meets the basic requirements for corrosion prevention, rust prevention and surface aesthetics in mass production.

[0003] Traditional bar surface coating equipment is poorly adaptable to bars of different diameters, shapes, or lengths, often requiring downtime for adjustments or component replacements. This results in low production efficiency, frequent manual intervention, and potential uneven coating. To address these issues, we propose a new bar surface coating system. Utility Model Content

[0004] The purpose of this invention is to provide a bar surface spraying equipment to solve the problems mentioned in the background art, such as poor adaptability when facing bars of different diameters, shapes or lengths, the need to stop the machine to adjust or replace some components, resulting in low production efficiency and frequent manual intervention.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bar surface spraying device, comprising: a housing, a conveying component inside the housing for conveying placed bars into the housing, a fixing component at the top of the housing for clamping the bars conveyed by the conveying component and pushing the bars to the spraying station, and a spraying component at the end of the housing for spraying paint on the surface of the bars located at the spraying station.

[0006] The conveying assembly includes multiple drive wheels, which are rotatably connected to the housing. Each drive wheel has a belt on its outer side. One drive wheel is coaxially and fixedly connected to a drive motor, which is installed inside the housing. A support roller is fixedly connected to the outer side of the drive wheel. The drive motor drives the drive wheel to rotate, which in turn drives the belt, causing the multiple drive wheels to rotate synchronously. The drive wheels then drive the support roller to rotate, thus achieving stable conveying of the bar stock within the equipment. This conveying structure operates stably, ensuring the bar stock maintains a uniform speed during the coating process, avoiding uneven coating or missed areas caused by unstable operation. It is suitable for large-scale continuous production.

[0007] The fixing component includes a guide rail fixed to the housing, a sliding wheel slidably connected to the guide rail, a support plate fixedly connected below the sliding wheel, a jaw positioning plate fixedly connected below the support plate, a jaw positioning plate fixedly connected to a jaw arm, and a jaw arm connected to a cylinder. The cylinder drives the jaws via a pneumatic rod, thereby achieving automatic clamping and positioning of bars of different diameters and shapes. This structure can automatically adjust the clamping position according to the size of the bar, ensuring stable and reliable clamping, preventing the bar from shifting or shaking during the spraying process, and improving the consistency of spraying quality and the adaptability of the equipment.

[0008] The spraying assembly includes a compression spring fixedly connected to the inner wall of the housing, and a roller fixedly connected above the compression spring. When the roller contacts the surface of the rod, it automatically adheres to the surface through the elastic force of the compression spring, providing auxiliary support and dynamic following, ensuring that the spray gun maintains the optimal spraying distance from the surface of the rod. A spray gun baffle is fixedly connected to the lower half of the housing, and the spray gun is fixedly installed on the spray gun baffle. The spray gun can be selected for liquid spraying or powder spraying according to process requirements to achieve uniform spraying on the surface of the rod, ensuring consistent coating thickness, strong adhesion, and meeting various performance requirements such as corrosion resistance, wear resistance, and aesthetics.

[0009] One end of the chuck is equipped with a rubber anti-slip edge, which further enhances the clamping stability, prevents damage to the surface of the bar during the clamping process, and improves the safety and applicability of the equipment.

[0010] The support rollers are equipped with anti-slip sleeves to enhance friction, prevent the bars from slipping during transport, and ensure their smooth movement.

[0011] This utility model has at least the following beneficial effects: The bar surface spraying equipment provided by this utility model has a fixing component that can automatically clamp workpieces of different specifications to prevent displacement and improve spraying quality. The spraying component achieves automatic contact through springs and rollers, assisting the spray gun to spray evenly. One end of the chuck is equipped with a rubber anti-slip edge to enhance clamping stability and avoid damage to the workpiece. The surface of the supporting roller is equipped with an anti-slip sleeve to enhance friction and prevent the bar from slipping during transportation. The equipment is easy to operate, runs stably, and is suitable for various bar spraying needs, making it highly practical. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 Please see Figure 1-4 This utility model provides a technical solution: a bar surface spraying device, comprising: a housing 1, a conveying component 2 inside the housing 1, the conveying component 2 conveying the placed bar into the housing 1, a fixing component 3 at the top of the housing 1, the fixing component 3 clamping the bar conveyed by the conveying component 2 and pushing the bar to the spraying station, and a spraying component 4 at the end of the housing 1, the spraying component 4 spraying paint on the surface of the bar located at the spraying station.

[0016] The conveying assembly 2 includes multiple drive wheels 22, which are rotatably connected to the housing 1. A belt 21 is provided on the outer side of each drive wheel 22. One of the drive wheels 22 is coaxially fixedly connected to a drive motor 23, which is installed inside the housing 1. A support roller 24 is fixedly connected to the outer side of the drive wheel 22. The drive motor 23 drives the drive wheel 22 fixedly connected to it to rotate, and the drive wheel 22 drives the belt 21 to rotate, thereby making the multiple drive wheels 22 rotate synchronously. The drive wheel 22 drives the support roller 24 to rotate, thereby conveying the bar material at a uniform speed along the length of the housing 1 to the area of ​​the fixed assembly 3.

[0017] The fixing component 3 includes a guide rail 36 fixed on the housing 1. A sliding wheel 37 is slidably connected to the guide rail 36. A support plate 38 is fixedly connected above the sliding wheel 37. A claw arm 34 is fixedly connected below the support plate 38. The claw arm 34 is fixedly connected to a claw positioning plate 35. The claw positioning plate 35 is connected to a cylinder 32. The cylinder 32 drives the claw 31 to move through a pneumatic rod 33, thereby realizing automatic clamping and positioning of bars of different diameters and shapes. When the bar moves to the area of ​​the fixing component 3, the sliding wheel 37 on the guide rail 36 is activated. The sliding wheel 37 drives the support plate 38 to move towards the bar. The claw arm 34 moves with the support plate 38 until the claw 31 contacts the surface of the bar. The cylinder 32 drives the claw 31 to open and close through the pneumatic rod 33. The claw 31 clamps the bar. The sliding wheel 37 slides along the guide rail 36, pushing the claw arm 34 to move the clamped bar to the area of ​​the spraying component 4, completing the positioning. This structure can automatically adjust the clamping position according to the size of the rod, ensuring stable and reliable clamping, preventing the rod from shaking or shifting during the spraying process, and improving the consistency of spraying quality and the adaptability of the equipment.

[0018] The spraying assembly 4 includes a compression spring 41 fixedly connected to the inner wall of the housing 1. A roller 42 is fixedly connected above the compression spring 41. When the roller 42 contacts the surface of the rod, it automatically adheres to the surface through the elastic force of the compression spring 41, providing auxiliary support and dynamic following, ensuring that the spray gun maintains a constant spraying distance from the surface of the rod. A spray gun 43 is fixedly installed on the top of the housing 1. The spray gun can select liquid spraying or powder spraying according to actual process requirements to achieve efficient and uniform spraying of the surface of the rod, ensuring consistent coating thickness and strong adhesion, and meeting various performance requirements such as corrosion resistance, wear resistance, and aesthetics. When the rod enters the spraying assembly 4, the roller 42 adheres tightly to the surface of the rod through the elastic force of the compression spring 41, ensuring that the roller 42 moves synchronously with the rod, maintaining a constant distance between the spray gun 43 and the surface of the rod. The spray gun 43 selects liquid or powder spraying mode according to process requirements, and guides the coating to evenly cover the surface of the rod through the spray gun baffle 44.

[0019] Example 2 In this second embodiment, the other structures remain unchanged. One end of the chuck 31 is provided with a rubber anti-slip edge 5. This structure can better fit the surface of the bar and is especially suitable for clamping workpieces with round or irregular cross-sections. It avoids indentation or damage to the surface of the bar during clamping and enhances clamping stability. The surface of the support roller 24 is provided with an anti-slip sleeve 6 to enhance friction and prevent the bar from slipping during transport, ensuring its smooth movement.
