The main types include ring die pellet machine and flat die pellet machine, which are selected according to different needs and scales. Among them, the flat die pellet machine is a device that compresses materials into pellets. Its working principle is to feed the raw materials into the flat die through the feed port, and the die and pressure rollers are squeezed to form pellets, and then cut into specified lengths by a cutter.

There are two fixed rings, and the bottom of the fixed ring is fixedly connected to an inclined rod, and the end of the inclined rod away from the fixed ring is fixedly connected to a scraper, and the bottom contact of the scraper is arranged on the top of the granulation plate.

[0015] A method for using a granulating device for straw recycling comprises the following steps:

[0016] Step 1: Place the material on the top of the granulation plate, start the motor, the motor drives the rotating shaft to rotate, the rotating shaft drives the bearing frame to rotate, the bearing frame drives the roller shell to rotate, so that the material passes through the circular hole of the granulation plate and moves downward to the inside of the bottom shell;

[0017] Step 2: When the material enters the bottom shell, the rotating shaft drives the scraper sleeve to rotate, and during the rotation of the rotating shaft, the rotating shaft drives the reciprocating thread sleeve to rotate. During the rotation of the reciprocating thread sleeve, the thread sleeve frame performs reciprocating lifting and lowering motion, and when the thread sleeve frame moves downward;

[0018] Step 3: The threaded sleeve drives the rotating plate to move downward. The threaded sleeve is limited by the limit frame, so that the threaded sleeve can be lifted vertically, and the rotating plate can drive the slider to slide along the outer wall of the limit frame, so that two adjacent sliders move away from each other;

[0019] Step 4: The slider drives the fixed plate to move, and the fixed plate drives the arc cotton to move. During the movement of the arc cotton, it can come into contact with the top of the outer wall of the roller shell. When the roller shell rolls and crushes the material, the roller shell will rotate around the bearing frame.

[0020] The present invention has the following beneficial effects:

[0021] (1) In the present invention, the material is placed on the top of the granulation plate, and the motor is started. The motor drives the rotating shaft to rotate, the rotating shaft drives the bearing frame to rotate, and the bearing frame drives the roller shell to rotate. During the rotation of the roller shell, the material on the top of the granulation plate is rolled, so that the material passes through the circular hole of the granulation plate and moves downward to the inside of the bottom shell. In this process, the material is molded into a cylindrical shape by the pressure. When the material enters the inside of the bottom shell, the rotating shaft drives the scraper sleeve to rotate. During the rotation of the scraper sleeve, the cylindrical material is cut, so that the granulated material falls to the top of the inclined shell. Due to the inclined setting of the inclined shell, the material slides to the discharge pipe, and the material is discharged outward through the discharge pipe, thereby performing the collection work. During the rotation of the rotating shaft, the rotating shaft The movable shaft drives the reciprocating wire sleeve to rotate. During the rotation of the reciprocating wire sleeve, the threaded sleeve frame performs reciprocating lifting and lowering motion. When the threaded sleeve frame moves downward, the threaded sleeve frame drives the rotating plate to move downward. Limited by the limit frame, the threaded sleeve frame can first be lifted vertically, and the rotating plate can drive the slider to slide along the outer wall of the limit frame. The two adjacent sliders move away, and the slider drives the fixed plate to move. The fixed plate drives the arc-shaped cotton to move. The arc-shaped cotton can contact the top of the outer wall of the roller shell during movement. When the roller shell rolls and crushes the material, the roller shell will rotate around the bearing frame. At this time, the material adhering to the top of the roller shell will be scraped off by the arc-shaped cotton to prevent the material from adhering to the outside of the roller shell, thereby improving the forming efficiency of the material.

[0022] (2) In the present invention, when the slider moves, the slider drives the arc plate to move. During the movement of the arc plate, the arc plate will come into contact with the block, and the arc plate will squeeze the block, causing the block to slide along the outer wall of the slide groove. The block drives the round rod to slide, and the round rod drives the rotating ring to slide. The rotating ring drives the circular plate to slide back and forth in the inner cavity of the roller shell. During the process of the circular plate sliding back and forth in the inner cavity of the roller shell, the repeated friction generated causes the inner wall of the roller shell to heat up. After the roller shell is heated, the material adhered to the outer wall is dried, thereby preventing a large amount of material from adhering. At the outer wall of the roller shell, it can reduce the moisture content in the material. When the fixed plate moves, the fixed plate drives the reset spring to move, the reset spring drives the sliding rod to move, and the sliding rod drives the arc plate to move. When the arc plate moves to one side of the roller shell, it is affected by the reaction force of the roller shell and the elastic deformation of the reset spring, and the arc plate no longer slides. At this time, the arc plate drives the sliding rod to slide along the inner wall of the fixed plate and the sliding block, preventing the slider from being stuck when the arc plate moves, so that the slider can continue to slide on the outer wall of the limit frame, thereby improving the stability of the device operation.

[0023] (3) In the present invention, when the circular plate slides inside the roller shell, the circular plate drives the friction plate to move, causing the air inside the roller shell to heat up. At this time, the spring is elastically deformed, and the spring squeezes the circular plate. When the circular plate slides toward the rotating ring, the circular plate and the friction plate move together, so that the hot air flow inside the roller shell enters the interior of the annular shell through the circular tube. The air flow is discharged outward through a plurality of air holes provided on the outer wall of the annular shell, and can perform jet treatment on the arc cotton moved above the annular shell, thereby preventing the attachment of materials to the outer wall of the arc cotton after the arc cotton is scraped and cleaned, thereby improving the cleaning effect of the arc cotton.

[0024] (4) In the present invention, when the roller shell rolls the material, the material is squeezed by the roller shell and may move to the area where the roller shell does not contact the granulation plate. The material is thus piled up, which affects the granulation efficiency of the material. At this time, when the block moves, the block drives the fixed ring to slide, the fixed ring drives the inclined rod to slide, the inclined rod drives the scraper to slide, and the two scrapers move away from each other. During the movement of the scraper, the materials gathered in a pile are scraped, so that the materials are moved again to the area where the roller shell contacts the granulation plate, thereby indirectly improving the granulation efficiency of the material.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1, please refer to Figure 1 - Fig. 9 As shown, the present invention is a granulation device for straw recycling and a method of using the same, comprising a bottom shell 1, one side of the bottom shell 1 is connected to a discharge pipe 2, the top of the bottom shell 1 is fixedly connected to a top shell 3, and further comprising;

The outer walls of both ends of the bearing frame 44 are rotatably connected to roller shells 453, and the material is placed on the top of the granulating plate 451, and the motor 42 is started. The motor 42 drives the rotating shaft 43 to rotate, and the rotating shaft 43 drives the bearing frame 44 to rotate, and the bearing frame 44 drives the roller shell 453 to rotate. During the rotation of the roller shell 453, The material on the top of the granulation plate 451 is rolled, so that the material moves downward to the inside of the bottom shell 1 through the circular hole of the granulation plate 451. In this process, the material is molded into a cylindrical shape due to the pressure. When the material enters the inside of the bottom shell 1, the rotating shaft 43 drives the scraper sleeve 452 to rotate. The scraper sleeve 452 cuts the cylindrical material during rotation, so that the granulated material falls to the top of the inclined shell 41. Due to the inclined setting of the inclined shell 41, the material slides to the discharge pipe 2, and the material is discharged outward through the discharge pipe 2, thereby performing collection work.

[0042] A reciprocating thread sleeve 454 is fixedly connected to the outer wall of the top end of the rotating shaft 43, and a threaded sleeve frame 455 is threadedly connected to the outer wall of the top end of the reciprocating thread sleeve 454. The bottoms of both ends of the threaded sleeve frame 455 are rotatably connected to rotating plates 456 respectively. The rotating plates 456 are arranged in four. The two sides of the bearing frame 44 are fixedly connected to the limiting frames 457 respectively. The purpose of this arrangement is to enable the threaded sleeve frame 455 to perform vertical lifting movement on the outer wall of the reciprocating thread sleeve 454.

[0043] One end of the rotating plate 456 away from the threaded sleeve 455 is rotatably connected to a slider 458, the inner wall of the slider 458 is slidably connected to the outer wall of the limit frame 457, one end of the slider 458 is fixedly connected to a fixed plate 459, and the bottom of the fixed plate 459 is fixedly connected to an arc-shaped cotton 4510.

[0044] A heating component 46 is provided on the top of the bearing frame 44. The heating component 46 includes a slide groove 461 opened at both ends of the top of the bearing frame 44. The side of the slider 458 away from the fixed plate 459 is fixedly connected to the arc plate 462, and the inner wall of the slide groove 461 is slidably connected to the block 463. The purpose of this setting is to limit the moving trajectory of the block 463. One side of the arc plate 462 is in contact with one side of the block 463. The side of the block 463 away from the arc plate 462 is fixedly connected to a round rod 464, and the end of the round rod 464 away from the block 463 is fixedly connected to a round plate 466.

[0045] The outer wall of one end of the round rod 464 is rotatably connected with a rotating ring 465. The purpose of this arrangement is to prevent the round rod 464 from getting stuck during the reciprocating movement. The outer wall of the rotating ring 465 is rotatably connected to the inner wall of the roller shell 453. The outer wall of the circular plate 466 is fixedly connected with a friction plate 467. The outer wall of the friction plate 467 is slidably connected to the inner cavity of the roller shell 453. Four springs 468 are fixedly connected around the side of the circular plate 466 away from the round rod 464. One end of the spring 468 is fixedly connected to one side of the inner cavity of the roller shell 453. When the slider 458 moves, the slider 458 drives the arc plate 462 to move. When the arc plate 462 moves, the arc Plate 462 will come into contact with block 463, and the arc plate 462 will squeeze block 463, so that block 463 will slide along the outer wall of slide groove 461, and block 463 will drive round rod 464 to slide, and round rod 464 will drive rotating ring 465 to slide, and rotating ring 465 will drive circular plate 466 to slide back and forth in the inner cavity of roller shell 453. During the process of reciprocating sliding of circular plate 466 in the inner cavity of roller shell 453, repeated friction will be generated to heat up the inner wall of roller shell 453. After roller shell 453 is heated, it will dry the material adhered to the outer wall, so as to prevent a large amount of material from adhering to the outer wall of roller shell 453 and reduce the water content in the material.

[0046] In Example 2, a cleaning assembly 47 is provided on one side of the roller shell 453, and the cleaning assembly 47 includes a circular tube 471 connected to the side of the roller shell 453 close to the rotating ring 465, one end of the circular tube 471 is connected to an annular shell 472, and one side of the annular shell 472 is fixedly connected to one side of the outer wall of the roller shell 453.

[0047] A plurality of air holes 473 are respectively provided around the outer wall of the annular shell 472, and sliding rods 474 are fixedly connected at both ends of the arc plate 462 close to the slider 458. One end of the sliding rod 474 passes through the fixed plate 459 and is slidably connected to the inner wall of the fixed plate 459. A return spring 475 is fixedly connected to the side wall of one end of the sliding rod 474. The purpose of this arrangement is to facilitate resetting. One end of the return spring 475 is fixedly connected to one side of the fixed plate 459.

[0048] Auxiliary components 48 are provided on both sides of the block 463. The auxiliary components 48 include fixed rings 481 fixedly connected to both sides of the block 463. Two fixed rings 481 are provided. The bottom of the fixed ring 481 is fixedly connected to an inclined rod 482. The end of the inclined rod 482 away from the fixed ring 481 is fixedly connected to a scraper 483. The bottom of the scraper 483 is contacted with the top of the granulating plate 451. When the roller shell 453 rolls the material, the material is squeezed by the roller shell 453 and may move to the point where the roller shell 453 is not in contact with the granulating plate 451. 1, these materials are piled up, thereby affecting the granulation efficiency of the materials. At this time, when the block 463 moves, the block 463 drives the fixed ring 481 to slide, the fixed ring 481 drives the inclined rod 482 to slide, the inclined rod 482 drives the scraper 483 to slide, and the two scrapers 483 move away from each other. During the movement of the scraper 483, the materials gathered in a pile are scraped, so that the materials are moved again to the area where the roller shell 453 contacts the granulation plate 451, thereby improving the granulation efficiency of the materials.

[0049] A method for using a granulating device for straw recycling comprises the following steps:

[0050] Step 1: Place the material on the top of the granulation plate 451, start the motor 42, the motor 42 drives the rotating shaft 43 to rotate, the rotating shaft 43 drives the bearing frame 44 to rotate, the bearing frame 44 drives the roller shell 453 to rotate, so that the material passes through the circular hole of the granulation plate 451 and moves downward to the inside of the bottom shell 1;

[0051] Step 2: After the material enters the bottom shell 1, the rotating shaft 43 drives the scraper sleeve 452 to rotate, and during the rotation of the rotating shaft 43, the rotating shaft 43 drives the reciprocating thread sleeve 454 to rotate. During the rotation of the reciprocating thread sleeve 454, the thread sleeve frame 455 performs a reciprocating lifting motion. When the thread sleeve frame 455 moves downward;

[0052] Step 3: The threaded sleeve 455 drives the rotating plate 456 to move downward, and is limited by the limiting frame 457. First, the threaded sleeve 455 can be lifted vertically, and the rotating plate 456 can drive the slider 458 to slide along the outer wall of the limiting frame 457, and two adjacent sliders 458 move away from each other;

[0053] Step 4: The slider 458 drives the fixed plate 459 to move, and the fixed plate 459 drives the arc cotton 4510 to move. The arc cotton 4510 can contact the top of the outer wall of the roller shell 453 during the movement. When the roller shell 453 rolls and crushes the material, the roller shell 453 will rotate around the bearing frame 44.

[0054] When in use, place the material on the top of the granulating plate 451, start the motor 42, the motor 42 drives the rotating shaft 43 to rotate, the rotating shaft 43 drives the bearing frame 44 to rotate, the bearing frame 44 drives the rolling shell 453 to rotate, and during the rotation of the rolling shell 453, the material on the top of the granulating plate 451 will be rolled, so that the material passes through the circular hole of the granulating plate 451 and moves downward to the inside of the bottom shell 1. In this process, the material is affected by the pressure and is molded into a cylindrical shape. When the material enters the inside of the bottom shell 1, the rotating shaft 43 drives the scraper sleeve 452 to rotate. During the rotation of the scraper sleeve 452, the cylindrical material is cut, so that the granulated material falls to the top of the inclined shell 41. Due to the inclined setting of the inclined shell 41, the material slides to the discharge pipe 2, and the material is discharged outward through the discharge pipe 2, thereby performing the collection work, and during the rotation of the rotating shaft 43, the rotating shaft 43 drives the reciprocating wire sleeve 454 to rotate. During the rotation of the reciprocating thread sleeve 454, the threaded sleeve frame 455 performs a reciprocating lifting motion. When the threaded sleeve frame 455 moves downward, the threaded sleeve frame 455 drives the rotating plate 456 to move downward. Limited by the limiting frame 457, the threaded sleeve frame 455 can first be lifted vertically, and the rotating plate 456 can drive the slider 458 to slide along the outer wall of the limiting frame 457, and the two adjacent sliders 458 move away from each other. The slider 458 drives the fixed plate 459 to move, and the fixed plate 459 drives the arc-shaped cotton 4510 to move. During the movement of the arc-shaped cotton 4510, it can come into contact with the top of the outer wall of the rolling shell 453. When the rolling shell 453 rolls and crushes the material, the rolling shell 453 will rotate around the bearing frame 44. At this time, the material adhering to the top of the rolling shell 453 will be scraped off by the arc-shaped cotton 4510 to prevent the material from adhering to the outside of the rolling shell 453, thereby improving the forming efficiency of the material.

[0055] When the slider 458 moves, the slider 458 drives the arc plate 462 to move. During the movement of the arc plate 462, the arc plate 462 will come into contact with the block 463. The arc plate 462 squeezes the block 463 to make the block 463 slide along the outer wall of the slide groove 461. The block 463 drives the round rod 464 to slide. The round rod 464 drives the rotating ring 465 to slide. The rotating ring 465 drives the circular plate 466 to slide back and forth in the inner cavity of the rolling shell 453. During the process of the circular plate 466 sliding back and forth in the inner cavity of the rolling shell 453, the repeated friction generated causes the inner wall of the rolling shell 453 to heat up. After the rolling shell 453 is heated, the material adhering to the outer wall is dried to prevent a large amount of material from adhering to the rolling shell. 453, and can reduce the moisture content in the material. When the fixed plate 459 moves, the fixed plate 459 drives the return spring 475 to move, the return spring 475 drives the sliding rod 474 to move, and the sliding rod 474 drives the arc plate 462 to move. When the arc plate 462 moves to one side of the roller shell 453, it is affected by the reaction force of the roller shell 453 and the elastic deformation of the return spring 475, and the arc plate 462 no longer slides. At this time, the arc plate 462 drives the sliding rod 474 to slide along the inner wall of the fixed plate 459 and the sliding block 458, preventing the arc plate 462 from causing the sliding block 458 to be stuck when moving, so that the sliding block 458 can continue to slide on the outer wall of the limit frame 457, thereby improving the stability of the device operation.

[0056] When the circular plate 466 slides inside the rolling shell 453, the circular plate 466 drives the friction plate 467 to move, so that the air inside the rolling shell 453 is heated up. At this time, it is elastically deformed by the spring 468, and the spring 468 squeezes the circular plate 466. When the circular plate 466 slides toward the rotating ring 465, the circular plate 466 and the friction plate 467 move together, so that the hot air flow inside the rolling shell 453 enters the interior of the annular shell 472 through the circular tube 471, and the air flow is discharged outward through the multiple air holes 473 provided on the outer wall of the annular shell 472, so that the arc cotton 4510 moved above the annular shell 472 can be sprayed, so as to prevent the outer wall of the arc cotton 4510 from being attached with materials after the arc cotton 4510 is scraped and cleaned, thereby improving the cleaning effect of the arc cotton 4510.

[0057] When the roller shell 453 rolls the material, the material is squeezed by the roller shell 453 and may move to the area where the roller shell 453 is not in contact with the granulation plate 451. The materials are thus piled up, which affects the granulation efficiency of the materials. At this time, when the block 463 moves, the block 463 drives the fixed ring 481 to slide, the fixed ring 481 drives the inclined rod 482 to slide, and the inclined rod 482 drives the scraper 483 to slide. The two scrapers 483 move away from each other. During the movement of the scraper 483, the materials gathered in a pile will be scraped, so that the materials are moved again to the area where the roller shell 453 is in contact with the granulation plate 451, thereby indirectly improving the granulation efficiency of the materials.
