[0019] The present invention also provides a method for using a filter device for processing resin materials, comprising the following steps:

[0020] S1. By starting the motor, the resin material in the heating barrel is intermittently transported to the inside of the annular filter in a rotating state, so as to filter the resin material and transport the filtered impurities;

[0021] S2. During the conveying of the resin material, the stirring rod is rotated inside the heating barrel to stir the resin material inside the heating barrel, so that the resin material inside the heating barrel is heated evenly, thereby improving the softening efficiency of the resin material;

[0022] S3. At the same time, during the process of conveying the resin material, the hammer plate can continuously beat the annular filter screen, so that the impurities adhering to the inner wall of the annular filter screen fall into the inside of the rectangular frame, thereby avoiding the impurities adhering to the annular filter screen and affecting the filtering effect.

[0023] Compared with the prior art, the invention has the following beneficial effects: the invention has a scientific and reasonable structure and is safe and convenient to use:

[0024] 1. An intermittent feeding assembly is provided. When filtering the resin material, the rotation of the second rotating shaft drives the first sealing rubber piston to slide inside the square outer box. When the first sealing rubber piston moves in the direction close to the elastic barrier sheet, the second sealing rubber piston slides into the interior of the lower sealing ring, and the third sealing rubber piston slides inside and out of the upper sealing ring. The gas enters the interior of the upper rectangular sealing box and flows out along the inside of the discharge pipe. When the first sealing rubber piston moves in the direction away from the elastic barrier sheet, the third sealing rubber piston slides into the interior of the upper sealing ring and fits with the end of the longitudinal pipe, so that the second sealing rubber piston slides inside and out of the lower sealing ring, thereby extracting the resin material inside the heating barrel and realizing intermittent delivery of the resin material;

[0025] By using an elastic barrier sheet, the resin material can be blocked, and the resin material on one side of the elastic barrier sheet and the air on the other side can be isolated. When the air pressure changes, the elastic barrier sheet can be deformed, thereby separating the resin material without affecting the transportation of the resin material.

[0026] 2. A filtering and collecting component is provided; when the circular disk, the connecting baffle, the annular disk and the annular filter rotate synchronously, the resin material can be filtered under the action of the annular filter, and the filtered resin material falls into the interior of the storage tank and flows out along the interior of the discharge tank. Under the action of the rotation of the annular filter, the resin material can be quickly filtered, and at the same time, the impurities filtered inside the annular filter and a small part of the resin material can be driven to move to the upper part of the annular filter, and fall into the interior of the rectangular frame under the action of gravity. The setting of the square filter can further filter the resin material, and the resin material inside the rectangular frame can flow into the interior of the collecting tank and flow out along the interior of the connecting pipe, which is conducive to filtering the impurities in the resin material, collecting and transporting the filtered impurities, and improving the convenience of resin material processing and filtering.

[0027] 3. A mixing and stirring assembly is provided. When the second sealing rubber piston moves, the tooth plate is driven to move. The movement of the tooth plate can drive the gear plate to rotate, thereby driving the stirring rod to rotate inside the heating barrel, thereby stirring the resin material inside the heating barrel, thereby improving the efficiency of uniform heating of the resin material inside the heating barrel;

[0028] By using a spring, a U-shaped clamping plate and a fixed plate, the second sealing rubber piston has a force in the direction of the feed connecting pipe under the action of the spring elastic potential energy, that is, when the first sealing rubber piston moves in the opposite direction, the second sealing rubber piston quickly slides into the interior of the lower sealing ring, and the tooth plate can move horizontally under the restriction of the U-shaped clamping plate and the fixed plate, thereby improving the accuracy of the second sealing rubber piston sliding into the interior of the lower sealing ring.

[0029] 4. A hammer assembly is provided. When the third sealing rubber piston moves upward and drives the fourth sealing rubber piston to slide upward inside the piston cover, the space of gas above the fourth sealing rubber piston is reduced, so that the rectangular rod sleeve moves upward on the surface of the fifth sealing rubber piston. When the third sealing rubber piston slides downward into the interior of the upper sealing ring, the space of gas above the fourth sealing rubber piston is increased, thereby extracting the gas inside the rectangular rod sleeve, so that the cross bar drives the hammer plate to move downward, so that the hammer plate applies force to the annular filter. The reciprocating movement of the third sealing rubber piston causes the hammer plate to reciprocate at the same time, which is conducive to continuous beating of the annular filter, so that impurities adhering to the inner wall of the annular filter fall into the inside of the rectangular frame, thereby avoiding the accumulation of impurities inside the annular filter affecting the filtering effect of the annular filter.

[0066] The present invention also provides a method for using a filter device for processing resin materials, comprising the following steps:

[0067] S1, by starting the motor 42, the resin material inside the heating barrel 2 is intermittently transported to the inside of the annular filter 46 in a rotating state, so as to filter the resin material and transport the filtered impurities;

[0068] S2. During the process of conveying the resin material, the stirring rod 68 is rotated inside the heating barrel 2 to stir the resin material inside the heating barrel 2, so that the resin material inside the heating barrel 2 is heated evenly, thereby improving the efficiency of softening the resin material;

[0069] S3. During the resin material conveying process, the hammer plate 77 can continuously beat the annular filter screen 46, so that impurities adhering to the inner wall of the annular filter screen 46 fall into the inside of the rectangular frame 413, thereby preventing impurities from adhering to the annular filter screen 46 and affecting the filtering effect.

[0070] Working principle: When filtering the resin material, the electric heating plate 3 and the motor 42 are connected to the external power supply, the electric heating plate 3 is started, and the resin material is added to the inside of the heating barrel 2. The resin material can be softened and plastically flowed under the heating of the electric heating plate 3, and the motor 42 is operated. The operation of the motor 42 drives the first rotating shaft 418 to rotate, and the rotation of the first rotating shaft 418 drives the circular disk 45 and the active bevel gear 522 to rotate. When the active bevel gear 522 and the driven bevel gear 521 are meshed and connected, the second rotating shaft 519 can be driven to rotate, and the rotation of the second rotating shaft 519 drives the rotating disk 517 to rotate, and the rotation of the rotating disk 517 drives the second rotating shaft 519 to rotate. The shaft pin 516 rotates with the second rotating shaft 519 as the axis, the transfer rod 513 can rotate on the surface of the second shaft pin 516, and the hollow rod 514 can rotate on the surface of the first shaft pin 512. When the second shaft pin 516 rotates, the transfer rod 513 can pull the hollow rod 514 to slide inside the guide groove 510, and the movement of the hollow rod 514 can drive the first sealing rubber piston 59 to slide inside the square outer box 58. When the first sealing rubber piston 59 moves toward the direction close to the elastic barrier sheet 56, the external gas flows into the inside of the square outer box 58 along the inside of the hollow rod 514, and the first sealing rubber piston 59 compresses the inside of the rectangular sealing box 52. The gas exerts a force on the second sealing rubber piston 525, causing the second sealing rubber piston 525 to slide into the interior of the lower sealing ring 526 and fit one end of the feed connecting pipe 523. The gas exerts a force on the third sealing rubber piston 527, causing the third sealing rubber piston 527 to slide inside the upper sealing ring 515 and slide out. The gas enters the interior of the upper rectangular sealing box 51 and flows out along the interior of the discharge pipe 524. When the first sealing rubber piston 59 moves in a direction away from the elastic barrier sheet 56, the gas on one side of the first sealing rubber piston 59 flows out from the interior of the square outer box 58 along the interior of the hollow rod 514. The rubber piston 59 extracts the gas inside the middle rectangular sealing box 52, and the gas exerts a force on the third sealing rubber piston 527, so that the third sealing rubber piston 527 slides into the interior of the upper sealing ring 515 and fits with the end of the longitudinal pipe 54. As the first sealing rubber piston 59 continues to move, the gas exerts a force on the second sealing rubber piston 525, so that the second sealing rubber piston 525 slides inside the lower sealing ring 526 and slides out, thereby extracting the resin material inside the heating barrel 2, so that the resin material inside the heating barrel 2 intermittently flows from the inside of the discharge pipe 524 into the inside of the transfer box 49, thereby realizing the transportation of the resin material;

[0071] The elastic barrier sheet 56 is provided to block the resin material, so that the resin material on one side of the elastic barrier sheet 56 is isolated from the air on the other side. The elastic barrier sheet 56 is made of a precious metal elastic alloy material with high strength, high elasticity, high melting point, and high use temperature. It can still maintain good elasticity at 700°C, so that when it comes into contact with the resin material at a higher temperature, it will not affect the shape and performance of the elastic barrier sheet 56, and the elastic barrier sheet 56 can be deformed when the air pressure changes. The elastic barrier sheet 56 is sealed and connected to the middle rectangular sealing box 52, so that the resin material can be separated without affecting the transportation of the resin material.

[0072] The resin material inside the transfer box 49 is transported along the inside of the feeding conduit 410 to between the annular disk 47 and the circular disk 45. When the first rotating shaft 418 drives the circular disk 45 to rotate, the rotation of the circular disk 45 drives the annular disk 47 to rotate through the connecting baffle 48, and at the same time drives the annular filter 46 to rotate synchronously. Under the action of the annular filter 46, the resin material can be filtered, and the filtered resin material falls into the inside of the storage trough 43 and flows out along the inside of the discharge trough 44. Under the action of the rotation of the annular filter 46, the resin material can be quickly filtered. During the rotation of the connecting baffle 48, the impurities and a small amount of resin material filtered inside the annular filter 46 can be driven to move. When the impurities and a small amount of resin material move to the upper part of the annular filter 46, they fall to the rectangular frame 4 under the action of gravity. 13, impurities and a small amount of resin material in the rectangular frame 413 slide along the inclined surface of the inclined plate 414 and slide to the position of the square filter screen 415. The setting of the square filter screen 415 can further filter the resin material. As the resin material and impurities accumulated on the square filter screen 415 continue to increase, the resin material and impurities in the rectangular frame 413 flow into the inside of the connecting groove 423 along the inside of the second through groove 422, flow along the inside of the connecting groove 423, and flow out from the inside of the first through groove 419. The resin material and impurities flowing out from the inside of the first through groove 419 fall into the inside of the collecting groove 411 and flow out along the inside of the connecting pipe 412, which is conducive to filtering the impurities in the resin material, collecting and transporting the filtered impurities, and improving the efficiency of resin material processing and filtering;

[0073] The rotation of the first rotating shaft 418 can drive the first retaining ring 420 and the second retaining ring 421 to rotate synchronously, and the first retaining ring 420 and the second retaining ring 421 are both in contact with the rectangular frame 413 on the sides away from each other, so as to prevent impurities from flowing out from the inside of the first auxiliary rotating hole 416;

[0074] In the process of intermittently conveying the resin material, the intermittent conveying of the resin material is achieved by the intermittent reciprocating movement of the third sealing rubber piston 527 and the second sealing rubber piston 525. When the second sealing rubber piston 525 is moving, the movement of the second sealing rubber piston 525 can drive the tooth plate 61 to move. During the movement of the tooth plate 61, the fixed plate 62 slides inside the auxiliary through groove 64, and the spring 63 is compressed. The movement of the tooth plate 61 can drive the gear plate 67 to rotate, and the rotation of the gear plate 67 drives the third rotating shaft 6 9 rotates, thereby driving the stirring rod 68 to rotate inside the heating barrel 2. Under the action of the elastic potential energy of the spring 63, the second sealing rubber piston 525 has a force in the direction of the feed connecting pipe 523, that is, when the first sealing rubber piston 59 moves in the opposite direction, the second sealing rubber piston 525 quickly slides into the interior of the lower sealing ring 526. The reciprocating movement of the second sealing rubber piston 525 can cause the stirring rod 68 to reciprocate, thereby stirring the resin material inside the heating barrel 2, thereby improving the efficiency of the resin material inside the heating barrel 2 being heated evenly;

[0075] During the movement of the tooth plate 61, the tooth plate 61 can move horizontally under the restriction of the U-shaped clamping plate 65 and the fixing plate 62, thereby improving the accuracy of the second sealing rubber piston 525 sliding into the lower sealing ring 526;

[0076] When the third sealing rubber piston 527 is moving, that is, when the third sealing rubber piston 527 moves upward, the movement of the third sealing rubber piston 527 drives the sealing slide rod 71 to move, and the movement of the sealing slide rod 71 drives the fourth sealing rubber piston 72 to slide inside the piston cover 73. The movement of the fourth sealing rubber piston 72 compresses the gas above the fourth sealing rubber piston 72, so that the gas above the fourth sealing rubber piston 72 is injected into the interior of the rectangular rod sleeve 78 along the interior of the air pipe 75. As the air pressure inside the rectangular rod sleeve 78 increases, the rectangular rod sleeve 78 moves upward on the surface of the fifth sealing rubber piston 79, and the movement of the rectangular rod sleeve 78 drives the cross bar 76 to move, and the movement of the cross bar 76 drives the hammer plate 77 to move in the direction away from the annular filter screen 46. When When the third sealing rubber piston 527 slides downward into the interior of the upper sealing ring 515, the space of the gas above the fourth sealing rubber piston 72 is increased, thereby extracting the gas inside the rectangular rod sleeve 78, so that the cross bar 76 drives the hammer plate 77 to move downward, so that the hammer plate 77 applies a force to the annular filter 46, and the reciprocating movement of the third sealing rubber piston 527 causes the hammer plate 77 to reciprocate at the same time, thereby achieving the effect of beating the annular filter 46, so that impurities adhering to the inner wall of the annular filter 46 fall into the interior of the rectangular frame 413, which is conducive to continuously beating the annular filter 46, so that the impurities adhering to the inner wall of the annular filter 46 fall into the interior of the rectangular frame 413, and avoid the accumulation of impurities inside the annular filter 46 affecting the filtering effect of the annular filter 46;

[0077] Under the action of the gravity of the cross bar 76, the hammer plate 77 and the rectangular rod sleeve 78, the third sealing rubber piston 527 always has the force to slide into the interior of the upper sealing ring 515, and the restriction of the longitudinal sliding of the sealing slide rod 71 can enable the third sealing rubber piston 527 to slide accurately into the interior of the upper sealing ring 515.
