[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 In this embodiment, a surface rust removal device for a weft inserting auxiliary nozzle includes a workbench 1. Support rods 2 are fixedly installed at both ends of the top of the workbench 1. A top plate 3 is fixedly installed between the tops of the two support rods 2. An adjustment mechanism 4 is provided on the lower side of the top plate 3.

[0021] The adjustment mechanism 4 includes a mounting box 401, on the front side wall of which a motor 402 is fixedly mounted, and a gear 403 rotatably mounted inside the mounting box 401 is fixedly mounted at the output shaft of the motor 402, and tooth plates 404 are meshed at the top and bottom of the gear 403, and connecting rods 405 are fixedly mounted on opposite sides of the two tooth plates 404, and rust removal rollers 406 are movably mounted at the bottoms of the two connecting rods 405.

[0022] Through the engagement between the gear 403 and the two tooth plates 404, when the motor 1 402 is started, the two tooth plates 404 can be moved relative to each other, thereby driving the two rust removal rollers 406 to move relative to each other through the two connecting rods 405 to adjust the distance between the two rust removal rollers 406, so as to meet the rust removal work of auxiliary nozzles of different sizes, solving the problem that the distance between the two grinding rollers of the above-mentioned utility model patent cannot be adjusted, so the rust removal operation cannot be performed on auxiliary nozzles of different sizes, which has limitations in use.

[0023] Slide grooves 408 are provided on the front side walls of the two tooth plates 404, and a slide rod 407 is fixedly installed on the front inner wall of the installation box 401 and is slidably connected to the inside of the two slide grooves 408. By setting up two slide grooves 408 and two slide rods 407, the stability of the two tooth plates 404 when moving left and right is improved.

[0024] There are two openings at the bottom of the installation box 401. The bottom ends of the two connecting rods 405 pass through the openings and extend to the top of the rust removal roller 406. The openings facilitate the connection between the two connecting rods 405 and the two rust removal rollers 406.

[0025] The tops of the two rust removal rollers 406 are fixedly mounted with threaded barrels, and the bottom ends of the two connecting rods 405 are threadedly connected to the threaded barrels. By providing the threaded barrels, the two rust removal rollers 406 can be disassembled and replaced.

[0026] A power assembly 5 is provided on the top of the installation box 401 . The power assembly 5 includes an electric push rod 501 . The electric push rod 501 is fixedly mounted on the top of the top plate 3 . A motor 2 502 is fixedly mounted on the driving end of the electric push rod 501 .

[0027] The outer surfaces of the two support rods 2 are slidably installed with movable sleeves 503, and a horizontal plate 504 is fixedly installed between the two movable sleeves 503. Motor 1 402 is fixedly installed on the top of the horizontal plate 504, and the output shaft of motor 2 502 passes through the horizontal plate 504 and is fixedly connected to the top of the installation box 401.

[0028] Under the action of the electric push rod 501, the motor 2 502, the horizontal plate 504 and the adjustment mechanism 4 can be driven to move up and down, thereby adjusting the rust removal height.

[0029] By providing two movable sleeves 503, the stability of the horizontal plate 504 when moving up and down is improved. Under the action of the motor 1 402, the installation box 401 is driven to rotate, thereby driving the two rust removal rollers 406 to rotate to perform rust removal work.

[0030] During implementation, follow these steps:

[0031] 1) First, the electric push rod 501 drives the motor 2 502 to descend, and the motor 1 402 drives the horizontal plate 504 to descend, thereby driving the adjustment mechanism 4 to descend, and lowering the adjustment mechanism 4 to the appropriate rust removal height;

[0032] 2) Then, the motor 1 402 drives the gear 403 to rotate, and the gear 403 drives the two tooth plates 404 to move in opposite directions. The two tooth plates 404 drive the two connecting rods 405 to move in opposite directions. The two connecting rods 405 drive the two rust removal rollers 406 to move in opposite directions until the two rust removal rollers 406 are adjusted to a suitable distance and contact the two sides of the auxiliary nozzle;

[0033] 3) Finally, the second motor 502 drives the installation box 401 to rotate, and the installation box 401 drives the two rust removal rollers 406 to rotate to remove rust from the surface of the auxiliary nozzle.

[0034] In summary, the surface rust removal device for the weft inserting auxiliary nozzle realizes flexible adjustment of the distance between the two rust removal rollers 406 by providing the adjustment mechanism 4. This design enables the device to adapt to nozzles of different sizes and adjust the rust removal rollers 406 to the most appropriate position to ensure efficient rust removal. Whether large or small nozzles, they can receive uniform and thorough rust removal treatment, significantly improving the applicability of the device.
