when the plastic medicine bottle is moved above the scraper, the fifth motor is started to drive the third supporting rod 707 to rotate, the movable rod 14 is driven to rotate through the matching of the spline and the spline groove, so that the plastic medicine bottle is driven to rotate, meanwhile, the water pump is started to spray and strip mixed liquid of the glue agent and water from top to bottom on the plastic medicine bottle, and the scraper is always contacted with the outer surface of the plastic medicine bottle, so that the label on the outer surface of the plastic medicine bottle and glue residues left between the plastic medicine and the label can be scraped; after the label of the plastic medicine bottle is scraped, the intermittent gear is just matched with the first gear, so that the conveyor belt is driven to move rightwards, meanwhile, the first gear drives 54 to rotate, 54 drives 53 to rotate, 53 drives 52 to rotate, 53 drives 51 to rotate, and 51 drives 36 to move downwards, so that when the scraper moves downwards, one end, opposite to the two telescopic scraping plates 909, of the scraper is always in contact with the two side faces of the scraper, the label and the fragments scraped from the two sides of the scraper can be removed from the scraper, the scraper can be continuously used, and the problem that the label of the plastic medicine bottle cannot be continuously removed by the scraper due to the fact that the label and the fragments are accumulated on the scraper is avoided; when the plastic medicine bottle is moved to the position right above the scraper, the intermittent gear is just separated from the first gear, so that the special ratchet rack moves upwards under the action of the spring, meanwhile, the special ratchet rack drives 539 to move upwards, and the 539 pushes 630 to turn upwards, so that the service life of the scraper is prevented from being influenced by abrasion of the scraper due to collision with 640 when the scraper moves upwards. Meanwhile, under the impact of water flow, the label and the debris on the upper surface of the inclined 630 are washed away along the inclined plane, so that the label on the scraper can be scraped continuously, the water flow can be gathered to the middle through the 631 to wash one end of the 909 close to the scraper, so that the impact of the water flow can be increased to wash away the label on the upper surface of the 909 conveniently, meanwhile, a part of the water flow can wash the scraper, and the effect of cleaning twice is achieved; the scraper is driven to move downwards when the conveyor belt moves, so that the abrasion of the body of the plastic medicine bottle on the scraper due to the scraping of the body on the scraper to the knife edge of the scraper can be avoided; the scraper can be always attached to the plastic medicine bottle through the arrangement of the spring, so that the label on the plastic medicine can be completely scraped after the plastic medicine bottle rotates three circles;
the blanking device comprises a blanking shell 58 arranged on the upper end surface of the base 1, a blanking space arranged in the blanking shell 58, a feeding hole 870 communicated with the rear end of the blanking space, an upright plate 59 fixedly arranged on the upper end surface of the base 1, a matching motor fixedly arranged in the upright plate 59, a blanking roller 60 fixedly arranged at the output end of the matching motor, a third groove arranged on the outer surface of the blanking roller 60 in the circumferential direction, an adjusting plate 61 movably arranged in the third groove, a plurality of telescopic oblique blocks 62 fixedly arranged on the upper end surface of the adjusting plate 61, and a matching spring fixedly arranged on the lower end surface of the adjusting plate 61 and the lower end wall of the third groove; the method comprises the following steps of taking off the labeled plastic medicine bottle from the equipment by using a blanking device; the plastic medicine bottle sleeved on the bottle 14 is driven to move forwards until the plastic medicine bottle falls into the blanking space by being driven to rotate by matching with the starting of a motor; the left end surfaces of the telescopic sloping blocks 62 are all arranged to be inclined planes, so that when plastic medicine bottles with labels removed are conveyed from left to right, the plastic medicine bottles can drive the telescopic sloping blocks 62 to move downwards, and the plastic medicine bottles can be prevented from being clamped by the telescopic sloping blocks when moving rightwards, being incapable of moving rightwards continuously and being taken down from equipment; when the bottleneck of plastics medicine bottle reachd 14 when the rotatory in-process of unloading roller 60 moved forward when the plastics medicine bottle during, because the bottleneck diameter of plastics medicine bottle is less than the body, the unloading roller can't contact with the bottleneck of plastics medicine bottle, can be when the bottleneck is located the top of unloading roller through the setting of flexible sloping block, thereby the flexible sloping block can stretch out from the third recess and can continue to drive plastics medicine bottle and move forward and drop to the unloading space in can continuing to drive the bottleneck contact of plastics medicine bottle, thereby avoid plastics medicine bottle card on 14 and make equipment can't continue the operation.
The working principle is as follows: remove step of label with label splitter as follows, put into the plastics medicine bottle, fixed cylinder starts to drive plastics medicine rearward movement, the plastics medicine bottle reachs on the carriage release lever, it is rotatory that the second motor starts to drive first friction pulley, thereby the external screw thread through plastics medicine bottle bottleneck is fixed on fixing device, first motor starts to drive intermittent gear, intermittent gear drives first gear revolve, thereby it removes to drive the conveyer belt, can soak the label paper of plastics medicine bottle when the plastics medicine bottle is removed to soaking in the device by the conveyer belt, the plastics medicine bottle after will soaking removes to scrape the label device and can carry out striking off of label, the unloading device follow equipment takes off is crossed to the plastics medicine bottle bucket after will striking off the label.
