Description

Technical Field

[0001] This utility model relates to the field of drum galvanizing technology, specifically a galvanizing and corrosion-resistant device for a sprocket conveyor drum. Background Technology

[0002] The galvanized anti-corrosion device for rollers is an important piece of industrial equipment. It is mainly used to improve the roller's corrosion resistance and extend its service life. The basic principle of galvanizing is to form a zinc film on the metal surface of the roller through electrochemical or hot-dip methods. This zinc film prevents the roller from directly contacting corrosive substances such as oxygen and moisture in the external environment, thus achieving the purpose of corrosion protection.

[0003] Existing galvanizing and anti-corrosion devices for rollers cannot provide positioning and support for rollers of different sizes. This means that different positioning structures need to be replaced when galvanizing rollers of different sizes to complete the galvanizing and support of the rollers. Therefore, a galvanizing and anti-corrosion device for sprocket conveyor rollers is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a galvanizing and corrosion-resistant device for sprocket conveyor rollers. It has the advantages of being able to position and support rollers of different models, thus solving the problem that it is impossible to position and support rollers of different sizes, which means that different positioning structures need to be replaced when galvanizing rollers of different models in order to complete the galvanizing and positioning of the rollers.

[0013] Furthermore, multiple rollers are fitted on opposite sides of the two arc-shaped positioning frames, and the multiple rollers are arranged vertically at equal intervals.

[0014] Compared with the prior art, this utility model provides a galvanized anti-corrosion device for sprocket conveyor rollers, which has the following beneficial effects:

[0015] 1. The galvanizing and anti-corrosion device of the sprocket conveyor roller is driven by a third electric telescopic rod to move the fixed frame connected to the outside of the winding reel, thereby adjusting the distance between the two fixed frames to meet the positioning requirements of different roller models and to achieve subsequent galvanizing.

[0026] Please see Figures 1 to 6This embodiment of a galvanized anti-corrosion device for a sprocket conveyor roller includes a galvanized anti-corrosion box 1. A fixing frame 11 is fixedly connected to the upper side of the galvanized anti-corrosion box 1. Two first drive motors 13 are mounted on the surface of the fixing frame 11. Each output end of the first drive motor 13 is fixedly connected to a movable wheel 24. A bearing 25 is sleeved on the side of the movable wheel 24 away from the first drive motor 13. A support plate 14 is inserted between the two bearings 25. Two second electric telescopic rods 15 are fixedly installed on the lower side of the support plate 14. An installation plate 16 is fixedly connected to the output end of the second electric telescopic rod 15. A positioning device 18 is provided on the outer side of the installation plate 16. The positioning device 18 includes a bidirectional motor 26 fixedly installed on the upper side of the mounting plate 16, a connecting plate 27 fixedly connected to the output end of the bidirectional motor 26, a third electric telescopic rod 28 fixedly installed on the side of the connecting plate 27 away from the bidirectional motor 26, a take-up reel 29 fixedly connected to the output end of the third electric telescopic rod 28, a connecting rope 17 fixedly connected to the outer side of the take-up reel 29, a fixing frame 20 fixedly connected to the lower side of the connecting rope 17, a bidirectional threaded rod 21 sleeved on the upper side of the fixing frame 20, and two arc-shaped positioning frames 23 threadedly connected to the outer side of the bidirectional threaded rod 21.

[0027] The galvanized anti-corrosion box 1 is equipped with a rust removal device. This device includes two partitions 2 fixedly connected to the inside of the box, two first electric telescopic rods 7 fixedly installed on the left side of one of the partitions 2, a support frame 8 fixedly connected to the output end of the first electric telescopic rods 7, a second drive motor 30 fixedly installed on one side of the support frame 8, a second rust removal roller 9 fixedly connected to the output end of the second drive motor 30, and two first rust removal rollers 6 sleeved on the left side of the inner wall of the galvanized anti-corrosion box 1. The side sleeve is equipped with two sprocket conveyor belts 10. A rust removal chamber 3 is opened on the left side inside the galvanized anti-corrosion box 1. A pickling chamber 4 is opened in the middle of the inner side of the galvanized anti-corrosion box 1. A galvanizing chamber 5 is opened on the right side inside the galvanized anti-corrosion box 1. A PLC controller 19 is embedded and installed on the front end face of the galvanized anti-corrosion box 1. A limiting hole 12 matching the moving wheel 24 is opened inside the fixed frame 11. A sliding groove matching the arc-shaped positioning frame 23 is opened inside the lower side of the fixed frame 20. A bearing seat is fixedly inserted on the side of the moving wheel 24 near the bearing 25.

[0028] Example 2:

[0029] Please see Figure 3 Based on Embodiment 1, it includes multiple rollers 22 respectively fitted on one side of the two arc-shaped positioning frames 23, with the multiple rollers 22 arranged vertically at equal intervals.

[0030] By adopting the above technical solution, when the two arc-shaped positioning frames 23 clamp the side of the roller and clean it for rust removal, the roller 22 can be driven to rotate during the positioning period by its own rotation, thereby cleaning the surface rust.

[0031] The working principle of the above embodiments is as follows:

[0032] The left-side sprocket conveyor belt 10 moves the roller below the fixed frame 11. Two first drive motors 13 start simultaneously, moving the moving wheel 24 within the limiting hole 12 and driving the positioning device 18 to move above the roller. The third electric telescopic rod 28 adjusts the distance between the two take-up reels 29, facilitating the fixed frame 20 to adjust and clamp the ends of rollers of different shapes. Then, the bidirectional motor 26 drives the take-up reel 29 to loosen the connecting rope 17, keeping the fixed frame 20 flush with the roller end. Both ends of the roller pass through the fixed frame 20. The bidirectional threaded rod 21 is then rotated to move the two rollers 22 closer to the side of the roller for clamping and positioning. Subsequently, the first drive motor 13 moves to the right above the rust removal chamber 3, and the bidirectional motor 26 continues to loosen the connection. Rope 17 moves the roller into the rust removal chamber 3 and keeps it between the first rust removal roller 6 and the second rust removal roller 9. The first electric telescopic rod 7 pushes the second rust removal roller 9 to contact the roller and makes the other side of the roller abut against the surface of the first rust removal roller 6. The second drive motor 30 starts the second rust removal roller 9 to actively remove rust from the rolling surface. In conjunction with the roller 22, the roller rotates synchronously, and the first rust removal roller 6 rolls passively and synchronously. After the rust removal work on the roller surface is completed, the connecting rope 17 is wound up and removed from the rust removal chamber 3. Then it is moved to the pickling chamber 4 to pickle the roller surface. Finally, the roller is placed in the galvanizing chamber 5 to complete the galvanizing and anti-corrosion treatment of the roller surface by hot dipping. Then it is placed above the sprocket conveyor belt 10 on the right side to transport the roller away.

Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply.
