Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to an anti-rust liquid spraying device for bar processing. Background Art

[0002] In the metalworking industry, bar stock, as an essential building block, is widely used in a variety of fields, including construction, machinery, and automotive. During production, finished bar stock is often cut to specific lengths and packaged to meet diverse customer needs. However, a key issue with this process is that after shearing, the original oxide layer on the bar ends is often destroyed, leaving the newly exposed metal surface directly exposed to the environment.

[0003] Especially in the southwest, where the unique climate creates high humidity, this high humidity significantly accelerates oxidation and corrosion on metal surfaces. Without the protective oxide layer, the ends of the bar are more susceptible to reaction with moisture and oxygen in the air, causing rust. This in turn damages the product's appearance and reduces its market value. Furthermore, rust can negatively impact the bar's mechanical properties, making subsequent processing and use more difficult.

[0004] To address the issue of rust on the ends of rods, the traditional approach is to manually apply anti-rust liquid. While this method can delay the onset of rust to a certain extent, it has significant limitations. First, manual application consumes a significant amount of human resources, increasing the labor intensity of workers and also increasing labor costs during the production process. Second, due to the many uncontrollable factors in manual operation, it is often difficult to ensure uniformity and consistency in the application, which affects the stability of the anti-rust effect and product quality. More importantly, manual application is inefficient and cannot meet the requirements of modern production for efficient and continuous operations, thereby slowing down the overall production pace and increasing production costs.

[0005] In view of the above problems, the industry urgently needs a more efficient and reliable solution to address the challenge of rod end corrosion. Summary of the Invention

[0006] The utility model provides a device for spraying anti-rust liquid for rods, which is an automatic spraying device. It not only achieves the purpose of rust prevention and improving the quality of finished products, but also can effectively reduce the impact of the additional process of manual spraying of anti-rust liquid on the production rhythm, thereby solving the problems caused by the manual application of anti-rust liquid on the existing rods.

[0007] In order to solve the above problems, the technical solution adopted by the present invention is:

[0009] In the above technical solution, a more specific technical solution can also be: the nozzle mounting bracket includes a vertical fixed bracket, a T-shaped adjustment bracket and a nozzle bracket, the vertical fixed bracket is installed on one side of the box body, the vertical rod of the T-shaped adjustment bracket is inserted into the vertical fixed bracket and fastened by adjusting screw 1; the cross bar of the T-shaped adjustment bracket is hollow, and the nozzle bracket passes through the inside of the cross bar of the T-shaped adjustment bracket and is fastened by adjusting screw 2.

[0010] Furthermore, a metal detector is provided on the nozzle, and the valve is a solenoid valve.

[0011] Furthermore, there are three nozzles, which are evenly distributed on the nozzle.

[0012] Furthermore, a one-way valve is provided on the air pipe.

[0018] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0019] 1. The utility model is an automatic spraying device, which not only achieves the purpose of preventing rust and improving the quality of finished products, but also effectively reduces the impact of the additional process steps of manually spraying rust-proof liquid on the production rhythm, thereby solving the problems caused by the manual application of rust-proof liquid on the existing rods: when the rods need to be treated with rust-proof treatment, the valve is opened to connect the power compressed air source through the air pipe 3 and the valve. The connected power compressed air is divided into two paths: one path of compressed air enters the box through the air pipe 1 and the box air inlet, compresses the rust-proof liquid stored in the box and delivers it to the nozzle through the box liquid outlet, pipeline, and nozzle liquid inlet; the other path of compressed air is directly delivered to the nozzle through the air pipe 2 and the nozzle air inlet, and merges with the rust-proof liquid at the nozzle of the nozzle to complete the spraying of the rust-proof liquid.

The spraying lasts for 1-2 seconds, and then a signal is given to command the lifting chain arm to rise. The finished bar is transported to the next process via the bar conveyor chain. The automatic spraying of the anti-rust liquid is repeated in sequence to achieve the purpose of rust prevention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings: Example

Therefore, when the rod needs to be treated with rust prevention, open the valve and connect the power compressed air source through the air pipe three and the valve. The connected power compressed air is divided into two paths: one path of compressed air enters the box through the air pipe one and the air inlet of the box, compresses the anti-rust liquid stored in the box and transports it to the nozzle through the liquid outlet of the box, the pipeline, and the liquid inlet of the nozzle; the other path of compressed air is directly transported to the nozzle through the air pipe two and the air inlet of the nozzle, and merges with the anti-rust liquid at the nozzle of the nozzle to complete the spraying of the anti-rust liquid.

[0028] A metal detector 17 is provided on the nozzle 9, and the valve 15 is a solenoid valve. When the metal detector 17 detects a signal of a bar 26, the information is sent to the solenoid valve 15, and the solenoid valve 15 starts to operate.

[0029] The nozzle mounting bracket 8 includes a vertical fixed bracket 8-1 for fixed support, a T-shaped adjustment bracket 8-2 for adjusting the position relationship between the nozzle and the rod 26, and a nozzle bracket 8-3 for installing the nozzle. The vertical fixed bracket 8-1 is installed on one side of the box 1. The vertical rod of the T-shaped adjustment bracket 8-2 is inserted into the vertical fixed bracket 8-1 and is fastened by an adjusting screw 18. When it is necessary to increase or lower the installation height of the nozzle, it can be achieved by loosening the adjusting screw 18 and moving the vertical rod of the T-shaped adjustment bracket 8-2 up and down; the cross bar of the T-shaped adjustment bracket 8-2 is hollow, and the nozzle bracket 8-3 passes through the inside of the cross bar of the T-shaped adjustment bracket 8-2 and is fastened by an adjusting screw 2 19. When it is necessary to open or shorten the distance between the nozzle and the rod 26, it can be achieved by loosening the adjusting screw 2 19 and moving the nozzle bracket 8-3 back and forth.

[0030] There are three nozzles 10, which are evenly distributed on the nozzle head 9. This arrangement makes the spray distribution more uniform.

[0031] A one-way valve 20 is provided on the air pipe 7, which can prevent the incoming air from flowing back and ensure that the rust-proof liquid can achieve the expected compression effect.

[0032] A one-way valve 21 is provided on the air pipe 14 to prevent the incoming air from flowing back and ensure that the anti-rust liquid can achieve the expected spraying effect.

[0033] A one-way valve 22 is provided on the pipeline 12. Such a setting can prevent the input rust-proof liquid from flowing back and ensure that the rust-proof liquid can achieve the expected spraying effect.

[0034] The solenoid valve 15 is a two-position five-way solenoid valve.

[0035] There are two liquid outlets 3 of the box body. Such an arrangement allows them to be used interchangeably to prevent the phenomenon that one of them cannot be used due to a problem.

[0036] It includes a bar conveyor chain 23, a lifting chain arm 24, and a lifting device 25; along the conveying direction of the bar conveyor chain 23, the utility model bar anti-rust liquid spraying device 27 is installed on both sides of the bar conveyor chain 23, and the nozzle 9 is respectively facing the two ends of the bar 26 on the bar conveyor chain 23.

[0037] The process of spraying the anti-rust liquid on the finished bar 26 using the anti-rust liquid spraying device 27 of the utility model is as follows:

[0038] Finished bar 26 is delivered to the weighing platform via bar conveyor chain 23 for positioning. The chain lift arm 24 is lowered, and the metal detector 17 on the bar anti-rust liquid spraying device 27 detects the presence of bar 26. This activates the solenoid valve 15, which delivers the anti-rust liquid from the housing 1 to the spray head 9. The compressed air supplied by the solenoid valve 15 to the spray head 9 completes the spraying process at the nozzle 10. The spraying process lasts for 1-2 seconds. A signal is then given to raise the chain lift arm 24, transporting the finished bar 26 via the bar conveyor chain 23 to the next process. This process is repeated to automatically spray the anti-rust liquid, achieving the desired rust prevention effect.

[0039] The method of adding rust-proof liquid is as follows: first open the box exhaust port 6 of the box 1 (to avoid liquid mist splashing when opening the refueling port), then open the cover of the box filling port 4, and add rust-proof liquid into the box 1 through the box filling port 4.

[0040] The method of draining the sewage is as follows: first open the box exhaust port 6 of the box 1, open the valve at the box sewage outlet 2, and drain the sewage in the box.

[0041] The method of spraying the anti-rust liquid is as follows: when the solenoid valve 15 is energized, the compressed air pressure presses the anti-rust liquid out from the liquid outlet 3 of the box body 1, and is transported to the nozzle 9 through the pipeline 12. When the solenoid valve 15 is energized, the compressed air is transported to the nozzle 9 through the air pipe 14. The anti-rust liquid and compressed air are sprayed through the nozzle at the same time to complete the spraying.
