when the dissolving machine works, the insoluble plastic is blocked by the partition plate in the prior art, because the plastic has larger volume and no air permeability, if the plastic covered on the surface of the partition plate is not cleaned in time, the filtering holes on the partition plate can be covered, the dissolving liquid can not flow in the dissolving box 1, and the workload of workers can be greatly increased by frequent cleaning, the technical scheme solves the problems, and the specific scheme is as follows, when the paper-plastic composite bag is dissolved and separated, the slightly heated paper-plastic composite bag is added into the dissolving box 1 from the feed inlet 2, meanwhile, the dissolving agent is added into the dissolving box 1 from the feed inlet 2, the dissolving agent can flow rightwards while dissolving the paper-plastic composite bag, the dissolving agent can flow out from the liquid outlet 3, the effect of recycling the dissolving agent is achieved, the dissolving agent can drive the paper-plastic composite bag to flow rightwards together to the filtering screen plate 5 while flowing, after the paper-plastic composite bag is dissolved for a certain period of time, the motor 7 is started, the motor 7 drives the threaded rod 6 to rotate, the threaded rod 6 drives the filter screen plate 5 to move upwards in the first sliding groove 4, the filter screen plate 5 drives the fourth push plate 25 to drive the third push plate 24 to move together towards the outer side of the dissolving tank 1 by extruding the second inclined surface 28 of the fourth push plate 25 when moving upwards, the third push plate 24 drives the second push plate 23 to move upwards, the second push plate 23 drives the second limit block 21 to move towards

push plate 34, then the air cylinder 12 is started to extend forwards, the air cylinder 12 drives the first scraping plate 11 to move forwards, the first scraping plate 11 scrapes the residues accumulated on the surface of the filter screen plate 5 forwards, the residues are separated from the top of the filter screen plate 5, the situation that the filter holes are blocked by the accumulated residues on the filter screen plate 5 is avoided, after the residues on the filter screen plate 5 are completely scraped by the first scraper 11, the cylinder 12 drives the first scraper 11 to move backwards to the initial position, then the motor 7 can start to rotate backwards, the filter screen plate 5 drives the second rack bar 33 to move downwards together under the action of the threaded rod 6, when the second rack bar 33 moves downwards to be meshed with the first gear 31, the second rack bar 33 acts on the first gear 31 to rotate the first gear 31, the first gear 31 drives the first rack bar 30 to move upwards, the first rack bar 30 drives the first push plate 19 to move upwards, at the moment, due to the limiting effect of the first limiting block 14 on the fixed block 17, the blocking plate 9 cannot move upwards, the first push plate 19 can only slide upwards in the third sliding groove 13 and simultaneously stretch the third spring 20, when the filter screen 5 moves downwards to make the bottom surface of the filter screen contact with the driving inclined plane on the first limit block 14, the filter screen 5 continues to move downwards to drive the first limit block 14 to move leftwards, so that the first limit block 14 is staggered with the fixed hole, when the first limit block 14 is just separated from the fixed hole, the bottom surface of the
