[0027] Reference Figure 1-Figure 5The utility model provides a technical solution: a filtering device for hot melt adhesive production, comprising a processing box 2, a filtering mechanism 1, a filter plate 18 and a filter column 19. The filtering mechanism 1 is a mechanism that can prevent the filter from being blocked. The filtering mechanism 1 comprises a motor 11, which is arranged on one side of the processing box 2. A fixed shaft 12 is arranged at the output end of the motor 11. A filter frame 17 is slidably arranged inside the processing box 2. A mounting rod 13 and a fixed rod 25 are arranged inside the processing box 2. Cams 16 are arranged on the surfaces of the mounting rod 13 and the fixed rod 25. The cam 16 is arranged at the bottom of the filter frame 17. Through the mutual cooperation of the motor 11, the fixed shaft 12, the mounting rod 13, the cam 16, the filter frame 17, the fixed plate 31 and the mounting plate 3, when the operator needs to prevent the filter from being blocked, the operator can first put the melt from the feed hopper 22 into the interior of the processing box 2, and then the operator can start the motor 11 to drive the fixed shaft 12 to The fixed shaft 12 rotates to drive the rotating wheel 14 to rotate, the rotating wheel 14 drives the first belt 15 to rotate, the first belt 15 drives the mounting rod 13 to rotate, the mounting rod 13 drives the mounting wheel 27 to rotate, and the mounting wheel 27 drives the fixed rod 25 to rotate through the second belt 28, so that the two groups of cams 16 rotate. When the two groups of cams 16 rotate to the bottom of the filter frame 17, the filter screens arranged inside the filter plate 18 and the filter bar 19 can be vibrated, so that the filter screens will not be blocked. When the two groups of cams 16 rotate to both sides, the two groups of fixed plates 31 can be resisted, and the fixed plates 31 squeeze the springs 32 and drive the mounting plate 3 to move. When the two groups of cams 16 are away from the fixed plates 31, the two groups of mounting plates 3 can rebound through the springs 32, so that the melt filtered inside the two sides of the processing box 2 can be shaken, so that the filter screens will not be blocked, thereby improving the filtering efficiency.
[0028] Reference Figure 1-Figure 5In a preferred embodiment, the filter plate 18 and the filter bar 19 are both arranged inside the filter frame 17, and mounting plates 3 are respectively arranged on both sides of the filter frame 17. A stirring rod 21 is arranged on the surface of the fixed shaft 12, and a heating baffle 23 is arranged inside the processing box 2. By setting the heating baffle 23, the operator can separate the processing box 2 into two areas, and the molten adhesive can be heated to facilitate subsequent filtration. A feed hopper 22 is arranged on the top of the processing box 2, and an outlet pipe 24 is arranged at the bottom of the heating baffle 23. A rotating wheel 14 is arranged on the surface of the fixed shaft 12 and the mounting rod 13, and a first belt 15 is arranged between the two groups of rotating wheels 14. A mounting wheel 27 is arranged on the surface of the mounting rod 13 and the fixed rod 25, and a second belt 28 is arranged between the two groups of mounting wheels 27. By setting the rotating wheel 14, the first belt 15, the mounting wheel 27 and the second belt 28 cooperate with each other, so that when the fixed shaft 12 rotates, The rotating wheel 14 is driven to rotate, and the rotating wheel 14 drives the first belt 15 to rotate. The first belt 15 drives the mounting rod 13 to rotate, and the mounting rod 13 drives the mounting wheel 27 to rotate. The mounting wheel 27 drives the fixed rod 25 to rotate through the second belt 28. Through the mutual cooperation of the fixed shaft 12, the stirring rod 21, the water outlet pipe 24, the filter plate 18 and the filter column 19, when the operator needs to filter various impurities, the operator can drive the stirring rod 21 to rotate when the fixed shaft 12 rotates, so that the molten rubber can be stirred. When the stirring is completed, the operator can control the valve on the surface of the water outlet pipe 24, so that the mixed material can fall to the top of the filter plate 18, and the material is selectively filtered for the first time. After the filtering is completed, it falls to the top of the filter column 19, so that the material can be selectively filtered multiple times, and impurities of different sizes can be filtered, which is convenient for the operator to use.
[0029] Reference Figure 1-Figure 5In a preferred embodiment, a drain pipe 26 is provided at the bottom of the treatment box 2, and valves are provided on the surfaces of the drain pipe 26 and the outlet pipe 24. By providing the valves, the water volume of the drain pipe 26 and the outlet pipe 24 can be controlled. Telescopic rods 29 are provided on both sides of the inner cavity of the treatment box 2, and the mounting plates 3 are provided on the surface of the telescopic rods 29. Springs 32 are provided on the opposite sides of the two sets of mounting plates 3, and fixing plates 31 are provided on the opposite ends of the two sets of springs 32. The two sets of fixing plates 31 are respectively provided on the mounting rods 13. On the side opposite to the fixing rod 25, installation doors are provided on both sides of the processing box 2. Filter nets are arranged inside the filter plate 18 and the filter bar 19. The mesh of the filter net inside the filter plate 18 is larger than the mesh of the filter bar 19. Through the above arrangement, the debris can be initially filtered. The filter plate 18 and the filter bar 19 are both detachable. By setting them to be detachable, the operator can remove the filter plate 18 and the filter bar 19 after the filter net has been used for a long time, and the operator can clean or replace the filter net.
[0030] Specifically, the working process or working principle of the filtering device for hot melt adhesive production is as follows: in the specific filtering of hot melt adhesive production, it is usually necessary to remove solid impurities and particulate matter in the molten adhesive before heating the molten adhesive, but the general device can only filter the sol alone, and the filtering effect is not good. After a long period of use, impurities will clog the filter holes on the filter plate. After the filter holes are clogged, not only will the filtering quality be affected, but also the filtering efficiency will be reduced, which is inconvenient for the operator to use. Therefore, the technical solution can solve the above problems. When the operator needs to prevent the filter from being blocked, When the operator first puts the melt from the feed hopper 22 into the processing box 2, the operator then starts the motor 11 to drive the fixed shaft 12 to rotate, the fixed shaft 12 rotates to drive the rotating wheel 14 to rotate, the rotating wheel 14 drives the first belt 15 to rotate, the first belt 15 drives the mounting rod 13 to rotate, the mounting rod 13 drives the mounting wheel 27 to rotate, the mounting wheel 27 drives the fixed rod 25 to rotate through the second belt 28, so that the two sets of cams 16 rotate, when the two sets of cams 16 rotate to the bottom of the filter frame 17 , the filter screens arranged inside the filter plate 18 and the filter bar 19 can be vibrated so that the filter screens will not be blocked. When the two sets of cams 16 rotate to both sides, the two sets of fixed plates 31 can be resisted, and the fixed plates 31 squeeze the springs 32 and drive the mounting plate 3 to move. When the two sets of cams 16 are away from the fixed plates 31, the two sets of mounting plates 3 can rebound through the springs 32, so that the melt filtered inside the two sides of the processing box 2 can be shaken, thereby preventing the filter screens from being blocked and improving the filtering efficiency. When the operator needs To filter various impurities, the operator can drive the stirring rod 21 to rotate when the fixed shaft 12 rotates, so as to stir the molten glue. After the stirring is completed, the operator can control the valve on the surface of the water outlet pipe 24 to allow the mixed material to fall to the top of the filter plate 18, and selectively filter the material for the first time. When the filtration is completed, it falls to the top of the filter column 19, so that the material can be selectively filtered multiple times to filter impurities of different sizes, which is convenient for the operator to use. At this point, all processes are completed.

Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
