[0069] The filtering component includes a melting and feeding part 2 which is fixed on the workbench 1. The melting and feeding part 2 includes a feeding pipe 21 arranged vertically. Inside the feeding pipe 21, there is a rotatable feeding roller 24. The spiral protrusions on the surface of the feeding roller 24 are in contact with the inner wall of the feeding pipe 21.

[0072] First, the impurities on the materials are removed by the impurity removing component 3, and then the materials in the molten state are filtered by the filtering component, so as to remove the impurities on both sides during the processing of epoxy resin, and improve the impurity removing effect.

[0073] Embodiment 1

[0074] As one of the embodiments of the present application, at the bottom of the feeding pipe 21, there is a first motor 23 which is fixed on the workbench 1. The output end of the first motor 23 penetrates through the bottom side wall of the feeding pipe 21 and is connected to the bottom of the feeding roller 24. The surface of the feeding pipe 21 is sleeved with a heating pipe 22. Inside the heating pipe 22, there is a heating element, and the heating element can be an electric heating wire.

[0075] The first motor 23 drives the feeding roller 24 to rotate. During the rotation, the feeding roller 24 pushes the materials to move upward in the feeding pipe 21. Under the heating of the heating pipe 22, the solid materials gradually become molten state.

[0076] Embodiment 2

[0077] As one of the embodiments of the present application, as Figure 3 and Figure 5 shown, the filtering part 9 includes a bearing shell 91 which is fixed on the top of the feeding pipe 21 and is fixed on the workbench 1 through a connecting rod. At the top of the feeding pipe 21, there is a connecting part which connects the melting and feeding part 2 and the filtering part 9;

[0078] A filtering shell 92 which is fixed in the inner cavity of the bearing shell 91. A filter screen 93 is laid at the bottom of the filtering shell 92. The filter screen 93 is made of rigid material, and the aperture of the filtering holes of the filter screen 93 is preferably between 10 and 100 microns.

[0079] The pressure filtering member is arranged at the top of the inner cavity of the filtering shell 92, and the pressure filtering member is driven by a connecting shaft 25 on the connecting part. A blanking pipe 911 is arranged at the bottom of the bearing shell 91, and the filtered material flows to the next processing step through the blanking pipe 911.

[0080] An annular shell is formed by downward protrusion at the outer edge of the bottom side wall of the bearing shell 91, and an annular filtering end is also formed by downward protrusion at the bottom side wall of the filtering shell 92. The filter net 93 is arranged inside the annular filtering end, which is convenient for the molten material to flow from the conveying pipe 211 into the filtering shell 92.

[0081] Further, the connecting part includes a conveying pipe 211. The top diameter of the feeding pipe 21 gradually decreases to form the conveying pipe 211. The conveying pipe 211 is connected to the bottom of the bearing shell 91 and communicates with the inner cavity of the bearing shell 91. A conveying screw 241 is fixed at the top of the feeding roller 24. The conveying screw 241 is located in the inner cavity of the conveying pipe 211, and the spiral protrusions on the surface of the conveying screw 241 are lapped with the inner wall of the conveying pipe 211. The top of the conveying screw 241 extends into the inner cavity of the filtering shell 92;

[0082] The connecting shaft 25 is fixed at the top of the conveying screw 241. The top end of the connecting shaft 25 is connected to the top side wall of the inner cavity of the bearing shell 91, and the connecting shaft 25 can rotate on the top side wall of the inner cavity of the bearing shell 91.

[0083] The conveying screw 241 rotates with the feeding roller 24, and the rotating conveying screw 241 pushes the molten material into the inner cavity of the filtering shell 92.

[0084] Specifically, as Figure 6 shown, the pressure filtering member includes a pressure filtering plate. The pressure filtering plate is slidably sleeved on the connecting shaft 25. A plurality of guiding telescopic rods 96 are connected to the top of the pressure filtering plate. The guiding telescopic rods 96 are fixed on the top side wall of the inner cavity of the bearing shell 91, and a first spring is sleeved on the surface of the guiding telescopic rods 96;

[0085] A driving unit, the driving unit includes a first bevel gear 252. The first bevel gear 252 is fixed on the surface of the connecting shaft 25, and a second bevel gear 253 is meshed and connected to one side of the first bevel gear 252;

[0086] A transmission shaft 97. One end of the transmission shaft 97 is fixed at the center of the second bevel gear 253. A bearing is sleeved on the surface of the transmission shaft 97, and the bearing is fixed on the inner wall of the bearing shell 91. The other end of the transmission shaft 97 is fixed to the center of the transmission gear 98. The transmission gear 98 is an incomplete gear, that is, the meshing teeth 981 on the transmission gear 98 are only distributed on the annular surface of a part of the transmission gear 98, as Figure 11 shown,Figure 11 The distribution of the meshing teeth 981 is schematically shown by a circular surface in the middle;

[0087] Furthermore, a transmission rack 99 meshing with the transmission gear 98 is arranged on one side of the transmission gear 98. The transmission rack 99 is slidably connected to the guide rail in the vertical direction, and the guide rail is fixed to the inner wall of the bearing shell 91. Figure 13 Schematically shows one connection method between the transmission rack 99 and the guide rail and one type of the guide rail. The bottom end of the transmission rack 99 can overlap with the filter plate.

[0088] A second spring is arranged on the transmission rack 99. One end of the second spring is fixed to the transmission rack 99, and the other end of the second spring is fixed to the guide rail passing through the bearing shell 91.

[0089] The connecting shaft 25 rotates along with the feeding roller 24. The rotating connecting shaft 25 drives the first bevel gear 252 to rotate. The first bevel gear 252 drives the second bevel gear 253 to rotate. The second bevel gear 253 drives the transmission gear 98 to rotate through the transmission shaft 97.

[0090] In this embodiment, during the rotation of the transmission gear 98, the meshing teeth 981 on its surface drive the transmission rack 99 to move downward during the rotation. The downward moving transmission rack 99 pushes the filter plate downward, and the filter plate moves downward, thereby pressing the material in the filter shell 92 to achieve pressure filtration. During this process, both the first spring and the second spring are stretched.

[0091] When the transmission gear 98 rotates to the area where there are no meshing teeth 981 on its surface, it no longer restricts the transmission rack 99. The transmission rack 99 returns to its original position driven by the contraction of the second spring, and then repeats the above process to achieve repeated pressure filtration of the material in the filter shell 92.

[0092] Preferably, the filter plate includes an inner connecting plate 94 and an outer connecting ring 95. The inner connecting plate 94 is of a circular structure, and the center of the inner connecting plate 94 is slidably sleeved on the connecting shaft 25. The outer connecting ring 95 is sleeved on the circular surface of the inner connecting plate 94, and the outer wall of the outer connecting ring 95 is attached to the inner wall of the filter shell 92.

[0093] The connection between the outer ring 95 and the inner plate 94 is a rotary sealing structure. The rotary sealing structure in this application has no innovation and is the same as the rotary sealing structure in the prior art. The surface of the inner plate 94 and the connecting shaft 25 is a sliding sealing structure. The inner plate 94 and the connecting shaft 25 are directly connected to each other through the limiting rod 251 of an "L" shape. The vertical part of the limiting rod 251 is connected to the inner plate 94 and is telescopic. The limiting rod 251 can make the inner plate 94 and the connecting shaft 25 rotate synchronously. When the inner plate 94 slides on the surface of the connecting shaft 25, only a sliding sealing structure is required. The sliding sealing structure in this technical solution has no innovation and is the same as the sliding sealing structure in the prior art;

[0094] By dividing the filter pressing plate into the outer ring 95 and the inner plate 94, the problem that both rotary sealing and sliding sealing need to be achieved at the contact part between the filter pressing plate and the connecting shaft 25 can be solved, and the difficulty and cost of implementing this technical solution are reduced.

[0095] Preferably, the top of the outer ring 95 and the top of the inner plate 94 are connected by a connecting piece 951. As Figure 10 shown, the connecting piece 951 includes two connecting rings. The two connecting rings are respectively embedded in the outer ring 95 and the inner plate 94. The tops of the two connecting rings are respectively connected with two connecting pipes of different sizes. The connecting pipes penetrate through the corresponding outer ring 95 and inner plate 94, and the tops of the two connecting pipes are connected to each other.

[0096] The outer ring 95 and the inner plate 94 are connected by the connecting piece 951 without interfering with the relative rotation between the outer ring 95 and the inner plate 94.
