[0018] The upper wall of the bottom rubbing table 21 is provided with a polishing groove 28, and the heald eye polishing assembly 26 is arranged in the polishing groove 28. The heald eye polishing assembly 26 comprises a polishing motor 261, a rotating block 262 and an eccentric polishing needle 263.

The eccentric polishing needle 263 and the side wall of the sliding groove 2621 are connected with a rubber band 264.

[0019] The polishing strips 29 are fixedly arranged at the center lines of the upper wall of the bottom rubbing table 21 and the lower wall of the top rubbing table 23, respectively. The upper wall of the bottom rubbing table 21 and the lower wall of the top rubbing table 23 are respectively symmetrically arranged with embedded sliding elastic auxiliary limiting rods 20. The connection between the elastic auxiliary limiting rods 20 and the bottom rubbing table 21 and the top rubbing table 23 is provided with springs, so that the elastic auxiliary limiting rods 20 have elastic expansion function.

[0020] The polishing blocks 2522 and the polishing strips 29 are both made of oilstone material, which can improve the polishing effect.

[0021] The polishing box 1 is internally provided with an inlet conveying belt 15 and an outlet conveying belt 16. The inlet conveying belt 15 penetrates the inlet 11, and the outlet conveying belt 16 penetrates the outlet 12.

[0022] The usage process of this embodiment includes the following steps: Step 1: The feeding conveyor belt 15 conveys the heddles to the upper wall of the bottom rolling table 21; Step 2: The hydraulic interactive component 24 operates, causing the bottom rubbing table 21 and the top rubbing table 23 to clamp and rub the heddle wire, while simultaneously centering the heddle wire. Step 3: The heddle polishing assembly 26 polishes the heddle eyes of the heddle wires; Step 4: The hydraulic interactive component 24 is reset, and the discharge conveyor belt 16 conveys the heddle wire out of the polishing box 1.

[0023] In step 1, the heddle wire is placed on the polishing strip 29 on the upper wall of the bottom rubbing table 21. The heddle wire passes through two pressure blocks 252 and between two elastic auxiliary limiting rods 20. The heddle eye on the heddle wire is located between the elastic auxiliary limiting rods 20 and the pressing centering piece 25.

[0024] Step 2, when executed, specifically includes the following process: Hydraulic pump 243 operates, driving hydraulic oil to flow. Hydraulic oil in the base of hydraulic rod 1 241 enters the base of hydraulic rod 244 through hydraulic pipe 242, and flows into the base of extrusion telescopic rod 221 through hydraulic through hole 2441 and connecting pipe 222. During this process, the push rod of hydraulic rod 1 241 gradually retracts, causing the bottom rubbing table 21 to slide to the left (towards...). Figure 2 For example, simultaneously, the push rod end of the compression telescopic rod 221 slides downward under hydraulic pressure, causing the top rubbing table 23 to gradually move downward and approach the bottom rubbing table 21, until the top rubbing table 23 and the bottom rubbing table 21 press the heddle wire tightly. The top rubbing table 23 then stops moving downward, while the hydraulic pump 243 continues to move, causing the hydraulic oil to extend the push rod of the hydraulic rod 244, thereby driving the top slide bar 22 and the top rubbing table 23 to slide to the right (for example). Figure 2 For example, the polishing strips 29 on the top rubbing table 23 and the bottom rubbing table 21 press and rub the upper and lower walls of the heddle wire to polish it. In the process of downward movement of the top rubbing table 23, the pressing centering piece 25 is also caused to act, and the close extrusion of the top rubbing table 23 and the bottom rubbing table 21 causes the pressing block 252 to slide into the sliding frame 251, thereby compressing the elastic air bag 253, and the gas in the elastic air bag 253 enters the base part of the gas pressure telescopic rod 254 through the built-in pipeline, thereby causing the push rod of the gas pressure telescopic rod 254 to slide out, the gas pressure telescopic rod 254 is elongated, and the elongation causes the two sliding frames 251 to approach each other, thereby causing the polishing block 2522 on the pressing block 252 to clamp the outside wall of the heald, and the polishing block 2522 on the pressing block 252 polishes the outside wall of the heald as the top rubbing table 23 and the bottom rubbing table 21 move horizontally. Since the pressing block 252 clamps the outside wall of the heald, the heald eye cannot pass the pressing block 252, and the multi-directional extrusion and limiting action of the pressing block 252 on the top rubbing table 23 and the bottom rubbing table 21 gradually drives the heald eye to the polishing groove 28, thereby achieving centering of the heald, and the hydraulic pump 243 stops running. The elastic auxiliary limiting rod 20 assists in limiting the heald during centering to prevent the heald from deviating.

[0025] Step 3 specifically includes the following flow: The polishing motor 261 is powered to operate, and at the same time, the electromagnetic ring 2611 is powered, the electromagnetic ring 2611 repels the magnet ring 2622, causing the magnet ring 2622 to drive the rotating block 262 to move upward, and the upper end of the eccentric polishing needle 263 enters the heald eye of the heald. The polishing motor 261 drives the rotating block 262 to rotate, and the rotating block 262 drives the eccentric polishing needle 263 to rotate. Due to the arrangement of the eccentric block 2631, the eccentric polishing needle 263 will gradually deviate from the axis of the rotating block 262 under the action of rotational centrifugal force and contact the inside wall of the heald eye. With the rotating movement, the eccentric polishing needle 263 polishes the inside wall of the heald eye, and the eccentric polishing needle 263 can automatically adhere to the inside wall of the heald eye by rotational centrifugal force, and can continuously and effectively adhere to and polish the heald eye of different shapes.

[0026] After polishing, the polishing motor 261 is powered off and stops running, the eccentric polishing needle 263 falls back into the polishing groove 28, the elastic string 264 causes the eccentric polishing needle 263 to return to the initial state, the hydraulic interaction assembly 24 reverses to reset, and the rubbing and polishing device 2 resets.

[0027] Example Two: Based on Example One, in order to improve the heald conveying efficiency, two clamping mechanical hands (not shown in the figure) are arranged inside the polishing box 1, one of which is located at the feeding conveyor belt 15 to assist in conveying the heald to the upper wall of the bottom rubbing table 21, and the other is located at the discharging conveyor belt 16 to assist in conveying the heald from the bottom rubbing table 21 to the discharging conveyor belt 16.

[0028] Embodiment three: based on embodiment one, a hydraulic sensor is arranged in the hydraulic pipe 242 to detect the hydraulic pressure in the hydraulic pipe 242, and the hydraulic sensor is electrically connected with the hydraulic pump 243.

[0029] During the execution of step 2, when the press block 252 on the top and bottom rubbing tables 23 and 21 presses the heald eye of the heald to the polishing groove 28, the press block 252 cannot continue to run, and the hydraulic pressure in the hydraulic pipe 242 will suddenly increase. When the hydraulic sensor detects the sudden change in hydraulic pressure, the control hydraulic pump 243 stops running.

[0030] The above describes the present application and its embodiments, which are not limited, and the drawings only show one of the embodiments of the present application, and the actual structure is not limited thereto.
