The working principle of the coating platform scraper gap adjusting mechanism for leather processing provided by the utility model is as follows:
when the leather scraping device is used, when a scraper 9 is needed to scrape dirt or glue and scrape materials on leather, the leather is firstly placed on a coating roller 3 according to the size and thickness of the leather, then the gap of the scraper 9 is adjusted, at the moment, a first rotating wheel is rotated to drive a corresponding first screw rod 6 to rotate, the first screw rod 6 rotates to drive a belt pulley to rotate, the other first screw rod 6 is driven to rotate together through belt transmission, the mounting blocks 5 are limited in corresponding mounting holes 4 in a sliding mode, at the moment, the two mounting blocks 5 move downwards stably together, the long block 8 is driven to move downwards stably through the two support shafts 7, and when the gap between the bottom of the scraper 9 and the leather on the coating roller 3 is needed, the first rotating wheel is stopped to rotate;
when the inclination angle of the scraper 9 needs to be adjusted, the scraper 9 can be conveniently adjusted to the most suitable inclination angle according to the thickness, the material and the like of leather, the damage to the leather is minimum when the scraper 9 scrapes dirt, the inclination angle is fixedly set in advance because the inclination angle of the existing scraper 9 is not adjustable, although the influence of the inclination angle adjustment is not large, for part of precious leather, the scraper 9 cannot be adjusted to the suitable inclination angle, the damage to the surface skin of the precious leather is large, at the moment, the crank is rotated to drive the worm 23 to rotate, the worm 23 rotates to drive the worm wheel 22 to rotate, the worm wheel 22 rotates to drive the corresponding fulcrum shaft 7 to rotate, the fulcrum shaft 7 drives the long strip block 8 to rotate, the long strip block 8 drives the scraper 9 to rotate to the suitable inclination angle, the crank can be stopped to rotate, and the scraper 9 cannot rotate due to the self-locking effect of the worm wheel 22 and the worm 23;
when the scraper 9 is used, a large amount of dirt, residual materials and the like remain on the scraper 9, and when the scraper 9 needs to be cleaned, because the clearance between the scraper 9 and the coating roller 3 is small, potential safety hazard exists in cleaning and the cleaning is inconvenient, at the moment, the two second screw rods 17 are rotated to drive the two support plates 18 to move downwards, when the two scraping blades 19 move downwards to the top parts of the two scraping blades 19 which are slightly lower than the top parts of the scraping blades 9, the second screw rods 17 stop rotating, at the moment, the two scraping blades 19 are separated from the corresponding avoiding grooves 10, and then the bidirectional screw rod 14 is rotated to drive the two moving blocks 15 to move close to each other until the two scraping blades 19 are attached to the outer walls of the two sides of the scraper 9, and finally the output shaft of the air cylinder 20 is controlled to extend and contract to quickly and safely clean the residual materials on the scraper 9, the two scraping blades 19 need to be continuously used after cleaning, and the two scraping blades 19 are moved into the avoiding groove 10 in the same way.
Compared with the prior art, the scraper gap adjusting mechanism of the coating platform for leather processing provided by the utility model has the following beneficial effects:
through the mutual matching of the vertical pile 2, the first screw rod 6, the fulcrum shaft 7, the long block 8, the scraper 9, the avoiding groove 10, the sliding block 11, the bidirectional screw rod 14, the moving block 15, the second screw rod 17, the supporting plate 18, the scraper 19, the cylinder 20, the worm wheel 22, the worm 23 and the like, the adjustment of the inclination angle of the scraper 9 can be realized by rotating the worm 23, and further the scraper 9 has better protection on leather when scraping dirt; when the gap between the bottom of the scraper 9 and the leather on the coating roller 3 needs to be adjusted, the gap can be adjusted by rotating the first screw rod 6; when the defective materials on the scraper 9 need to be cleaned, the scraper 19 can be clamped by adjusting the two-way screw rod 14 and the second screw rod 17, then the cylinder 20 is started to clean the defective materials, the cleaning is convenient and safe, and after the cleaning is finished, the scraper 19 is transferred into the avoiding groove 10, so that the normal use of the scraper 9 cannot be hindered.
