Through the impurity removal of the filter screen 10, the impurity content of the stock solution entering the injection molding pipe 4 is low, so that the impurity removal function of the stock solution is realized, the influence on the injection molding quality due to overhigh impurities is avoided, the reliability of the equipment is improved, meanwhile, the driving assembly is controlled to work to drive the rotating shaft 13 to rotate, the scraper blade 18 is driven to rotate through the first connecting rod 16 and the second connecting rod 17, the impurities adhered to the filter screen 10 can be scraped through the rotation of the scraper blade 18, the impurities cannot be adhered to the filter screen 10 all the time, the probability of blockage of the filter screen 10 is reduced, the influence on the circulation of the stock solution is avoided, the injection molding work cannot be influenced, the reliability of the equipment is improved, when the rotating shaft 13 rotates, the support plate 15 moves towards the direction far away from the rotating shaft 13 through the action of centrifugal force, the first spring 14 is stretched, the pressing plate 20 is driven to move, compress second spring 19, the second spring 19 of compression can give scraper blade 18 a decurrent power, make scraper blade 18 can support firmly with filter screen 10 and lean on, thereby the effect of scraping has been promoted, when pivot 13 rotates, can also drive carousel 22 and rotate, through the effect of centrifugal force, drive scraper blade 18 through bracing piece 23 and remove to the direction of keeping away from carousel 22, make carousel 22 support with gasbag 26 and lean on and extrude gasbag 26, compress third spring 27, make the leading-in jam-proof mechanism work of air in the gasbag 26, make jam-proof mechanism work, after the completion of moulding plastics, drive assembly stop work, make pivot 13 no longer rotate, and stripper plate 24 no longer receives the effect of centrifugal force, make stripper plate 24 no longer extrude gasbag 26, under the effect of restoring force of third spring 27, make gasbag 26 resume to original state. When the air bag 26 is extruded by the extrusion plate 24, air in the air bag 26 is introduced into the inner part of the air cylinder 30 through the branch pipe 29, the piston 32 moves downwards, the elastic rope 31 is stretched, raw liquid collected in the air cylinder 30 is reintroduced into the injection molding pipe 4 through the second through pipe 34, waste of the raw liquid is avoided, the environmental protection performance of the device is improved, after injection molding is completed, the rotating shaft 13 does not rotate any more, when the air bag 26 is no longer extruded by the extrusion plate 24, the piston 32 moves upwards through the restoring force of the elastic rope 31, the raw liquid remained in the connecting pipe 3 is introduced into the inner part of the air cylinder 30 through the first through pipe 33, the function of cleaning the connecting pipe 3 is realized, the phenomenon that the raw liquid is agglomerated in the connecting pipe 3 to block the connecting pipe 3 is avoided, the probability of blocking of the connecting pipe 3 is reduced, the influence on injection molding work is avoided, and the reliability of the device.

Compared with the prior art, the injection molding machine with the impurity removing function realizes the impurity removing function through the impurity removing mechanism, avoids the influence on the injection molding quality due to overhigh impurities, thereby improving the reliability of equipment, compared with the prior impurity removing mechanism, the impurity removing mechanism can also scrape the impurities adhered on the filter screen 10, so that the impurities can not be adhered on the filter screen 10 all the time, thereby reducing the probability of blocking the filter screen 10, avoiding the influence on the circulation of the stock solution, further not influencing the injection molding work, improving the reliability of the equipment, realizing the function of cleaning the connecting pipe 3 through the anti-blocking mechanism, avoiding the agglomeration of the stock solution remained in the connecting pipe 3 to block the connecting pipe 3, further reducing the probability of blocking the connecting pipe 3, avoiding the influence on the injection molding work, further improving the reliability of the equipment, compared with the prior anti-blocking mechanism, the anti-blocking mechanism and the impurity removing mechanism are an integrated linkage mechanism, the practicality is higher.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
