Then a collecting filter frame 10 is arranged just below the through hole 9, and then a knob 19 is screwed and connected to the side wall of the collecting filter frame 10, and a filter baffle 11 is fixedly connected to one side of the top of the collecting filter frame 10. At the same time, 11 is slidingly connected to the bottom wall of the filter screen 8, and two limit blocks 12 are symmetrically arranged at the top of the other side of the collection filter frame 10, and then the surfaces of the two limit blocks 12 are provided with plug holes 13, and at the same time, two limit seats 16 are arranged on the outer wall of the feed barrel 4 and above the two limit blocks 12, and then the surfaces of the two limit seats 16 are movably penetrated with plug rods 14 plugged and connected with the plug holes 13, and the tops of the two plug rods 14 are commonly connected with a toggle rod 15, and at the same time, the outer sides of the two plug rods 14 are fixedly sleeved with block blocks 18, and the outer sides of the two plug rods 14 are provided with springs 17 between the limit seats 16 and the block blocks 18, and finally the two ends of the spring 17 are respectively fixedly connected with the limit seats 16 and the block blocks 18;

[0023] When cleaning the impurities on the filter screen 8, the scraper 7 is first driven to rotate by the rotating rod 6, and then the rotating scraper 7 moves the impurities trapped on the filter screen 8, and then when the impurities are moved to the opening 9 on the surface of the filter screen 8, they fall into the collection filter frame 10 for collection. When the collection filter frame 10 collects a certain amount, the toggle rod 15 is pulled, and then the insertion rod 14 releases the limit of the limit block 12, and then the collection filter frame 10 is moved out of the feed barrel 4, and then the knob 19 is turned to collect the collection filter. The impurities collected in the frame 10 are discharged from the notch at the connection of the knob 19. The setting of this structure can clean the impurities on the filter screen 8 while feeding, without delaying the feeding process, thereby improving the working efficiency of the device. At the same time, when the collection and filter frame 10 is moved out of the feed barrel 4, the filter baffle 11 fixedly connected to the collection and filter frame 10 is pulled, so that the filter baffle 11 blocks the through port 9, thereby preventing the impurities from falling directly from the through port 9 into the mixing barrel 1 when the collection and filter frame 10 is moved out of the feed barrel 4.

[0025] Specific working principle:

[0026] When the device is in use, the material is first put into the mixing barrel 1 through the feed barrel 4, and then the raw materials in the mixing barrel 1 can be mixed and stirred through the setting of the stirring component 20, and then the scraper ring 22 is driven up and down by the electric push rod 21 to scrape the material attached to the inner wall of the mixing barrel 1, and finally the discharge pipe 3 is set to discharge the polyurethane foaming mixture in the mixing barrel 1. When the material is put into the feed barrel 4, the filter screen 8 in the feed barrel 4 will screen the impurities in the material, so that the impurities are trapped on the upper surface of the filter screen 8. When the impurities on the filter screen 8 need to be cleaned, the scraper 7 is first driven to rotate by the rotating rod 6, and then the rotating scraper 7 moves the impurities trapped on the filter screen 8. Then, when the impurities are pushed to the opening 9 on the surface of the filter screen 8, they fall into the collecting filter frame 10 for collection. When the collecting filter frame 10 collects a certain amount, the pushing rod 15 is pulled, and then the insert rod 14 releases the limit on the limit block 12, and then the collecting filter frame 10 is moved out of the feed barrel 4. Then, the knob 19 is turned to discharge the impurities collected in the collecting filter frame 10 from the notch at the connection of the knob 19. At the same time as the collecting filter frame 10 is moved out of the feed barrel 4, the filter baffle 11 fixedly connected to the collecting filter frame 10 is pulled, so that the filter baffle 11 blocks the opening 9, thereby preventing impurities from falling directly from the opening 9 into the mixing barrel 1 when the collecting filter frame 10 is moved out of the feed barrel 4.
