Description

Technical Field

[0001] The present invention relates to the technical field of polishing of roller fairleads, and specifically to a polishing device and method for a ship roller fairlead with a chip collection function. Background Art

[0002] A roller fairlead is a key device used to guide and protect cables in scenarios such as ships, docks, and lifting equipment. Its core function is to ensure the safe and smooth retraction and release of the cable by reducing the friction and wear between the cable and the equipment.

[0003] In the prior art, the flaky chips generated during grinding will rebound onto the drum. When the surface of the flaky chip is parallel to the flying direction, the sharp edge of the flaky chip will scratch the surface when it hits the drum, affecting the grinding quality; when the grinding wheel is used for high-hardness treatment, the abrasive grains are easily worn but do not fall off, resulting in a decline in the grinding effect of the grinding wheel. Frequent manual cleaning has low efficiency and also reduces the grinding efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a polishing device and method for a ship roller fairlead with a chip collection function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A polishing device for a ship roller fairlead with a chip collection function, which is used for polishing the drum of the roller fairlead.

[0006] The workbench is used to fix each component. The drum is sent to the clamping module by the polishing module for clamping.

The fixing plate is used for fixing each component. The flipping motor drives the worm to rotate, and the worm drives the flipping plate to rotate through the worm gear. The polishing motor controls the polishing roller to polish the roller. The limiting block on the flipping plate is used to hold up the roller for clamping. After clamping, it flips down by a certain angle to prevent the limiting block of the flipping plate from being worn when the roller rotates. After grinding, the flipping plate is flipped to let the polishing roller polish the roller, and the slag collection module can suck in the debris generated during grinding.

When the surface of the sheet chip is parallel to the flying direction, the sharp edge of the sheet chip will scratch the surface when hitting the roller, affecting the grinding quality. When the surface of the sheet chip is parallel to the flying direction, it is mainly divided into a horizontal state and a vertical state. The vertical guiding pipe sprays out an air flow to impact the surface of the sheet chip in the vertical state, and the sheet chip will rotate to face the surface towards the roller, preventing the sharp edge of the sheet chip from scratching the surface of the roller. The two vertical guiding pipes face each other and are placed staggeredly to prevent the gases at both ends from interfering with each other.

[0017] S2. The grinding module grinds the roller to remove the oxide layer and worn parts; the limiting block on the turning plate controls the roller to turn down a certain angle after clamping, and then controls the grinding wheel to start grinding;

[0018] S3. The debris guiding module adjusts the direction of the debris rebounding towards the roller; the sheet debris generated during grinding is easy to scratch the surface of the roller.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The clamping assembly can detect the offset of the roller and can automatically adjust to correct the deviation of the roller;

[0023] 2. The slag collection module can clean the debris adsorbed on the polishing roller due to static electricity, improving the polishing efficiency of the polishing roller. The impact nozzle can eject intermittent high-speed jets to remove the abrasive grains that cannot automatically fall off after wear on the grinding wheel, improving the grinding efficiency of the grinding wheel.

[0024] 3. The debris guiding module can adjust the surface orientation of the flaky debris to prevent the sharp edges of the flaky debris from hitting the surface of the polished roller. Description of the Drawings

[0058] S3. The chip guiding module 5 adjusts the direction of the chips rebounding towards the drum 7; the flaky chips generated during grinding are likely to scratch the surface of the drum 7. The chip guiding module 5 sprays airflows in different directions to impact the surface of the flaky chips, adjusting the surface orientation of the flaky chips, and reducing the damage when the flaky chips impact the drum 7 through surface collision.

[0059] S4.

The debris guiding module 5 sprays airflows in different directions to impact the surface of the flaky debris, adjusting the surface orientation of the flaky debris. The impact nozzle 6 intermittently introduces water flow and high-pressure air, and the high-pressure air increases the water flow speed. The high-speed water flow impacts and drops the abrasive grains that cannot fall off after wear on the grinding wheel 454. After the grinding is completed, the turning plate 36 is rotated by a certain angle, the polishing roller 38 is controlled to polish the drum 7, the slag collection box 391 collects the debris generated by polishing, the gas is ionized by the ionization needle 399, and the dust removal nozzle 396 sprays the gas with positive and negative charges to clean the debris on the polishing roller 38.
