Description

Technical Field

[0001] This invention relates to the field of plastic drying equipment technology, and more specifically to a raw material granule drying equipment. Background Technology

[0002] Automotive trim serves to decorate and beautify vehicles, and its quality directly impacts the car's interior and exterior image. Trim selection should be tailored to the specific needs of the vehicle, adhering to principles of aesthetics, harmony, practicality, and safety, to ensure optimal decorative effects. Common trim items include body decals, wheels, body kits, spoilers, roof racks, and interior ambient lighting. Plastic automotive trim items are generally manufactured using injection molding. During production, the plastic granules used for trim items need to be dried before being fed into the injection molding machine for further processing.

[0003] Chinese patent document CN222460027U discloses a vertical dryer, which includes a heating chamber. The inner wall of the heating chamber is fixedly installed with multiple sets of inclined feeding plates. Feeding channels are left between the multiple sets of feeding plates. The bottom of each set of feeding plates is fixedly installed with a mounting frame. A conveying main pipe is fixedly installed on the mounting frame. Multiple sets of conveying branch pipes for air conveying are symmetrically connected on the conveying main pipe. Multiple sets of air outlets are provided at the bottom of the conveying branch pipes. Electric heating wires for air heating are provided in each set of conveying branch pipes.

[0004] However, the structural design of the aforementioned technologies, while reducing the overall size of the equipment, requires a humidity sensor to trigger the opening of the discharge valve when the continuously discharging dryer discharges materials. If the humidity of the bottom layer of material does not meet the discharge standard, the discharge needs to be delayed until the discharge standard is met. This not only leads to the subsequent materials being over-dried, but also affects the normal material supply to the injection molding machine.

[0005] Therefore, a raw material particle drying device is proposed to solve the problems mentioned above. Summary of the Invention

[0006] This invention provides a raw material particle drying device, which aims to solve the problem in related technologies where the bottom layer material has not reached the drying standard and must be dried before the material can be discharged.

[0007] The raw material particle drying equipment of the present invention includes a feeding mechanism, a discharging mechanism on the feeding mechanism, and a turning mechanism rotatably arranged inside the discharging mechanism;

[0008] The discharge mechanism includes a guide assembly installed on the feeding mechanism and a sealing assembly for discharge. The guide assembly includes a fixed box, a circular receiving cavity, and a guide cavity with an inclined inner wall. The guide cavity and the receiving cavity are connected and are distributed vertically in the fixed box. The fixed box has a discharge port.

[0009] The material turning mechanism includes a rotating drum assembly rotatably disposed in the receiving cavity, a limiting assembly located inside the rotating drum assembly, multiple adjusting components I, multiple adjusting components II, and multiple material turning components disposed outside the rotating drum assembly;

[0010] The rotating drum assembly includes a rotating drum rotatably connected in the receiving cavity and multiple partitions installed on the outside of the rotating drum. Adjustment component one is installed between two partitions. There are two adjustment components two in each group and two material turning components in each group. The two material turning components are rotatably connected to adjustment component one. The two adjustment components two are located on both sides of adjustment component one. Adjustment component one and adjustment component two are in contact with the limiting component and can drive the material turning components to rotate back and forth.

[0011] During material drying, the material passes through the feeding mechanism into the fixed box. It then enters the receiving cavity via the guide chamber and falls between multiple baffles on the rotating drum, thus dividing the material into multiple portions. When the moisture content of the material at the discharge port is below the standard, gravity pushes the baffles and rotating drum to rotate, causing the material with the insufficient moisture content to move upwards and continue drying. During rotation, the rotating drum continuously pushes the adjusting components one and two via the limiting components. These components then drive two turning components to rotate back and forth between the two baffles, turning the material between them and accelerating the drying process. Simultaneously, the rotating drum also transfers other materials to the discharge port, ensuring that the dried material is discharged first, preventing undried material from blocking the discharge port and preventing the dried material from being discharged. This eliminates the need to wait for the bottom layer of material to dry before discharging, thereby improving material discharge efficiency.

[0012] Preferably, the sealing assembly includes a fixed frame, an electric telescopic rod, a connecting rod, and a sealing plate. The fixed frame is mounted on a fixed box, the electric telescopic rod is mounted on the fixed frame, the connecting rod is mounted on one end of the electric telescopic rod, the sealing plate is mounted on the connecting rod, the sealing plate is located at the bottom of the discharge port, and a moisture sensor is installed at the discharge port.

[0013] When the material is moved to the discharge port, the moisture content of the material is detected by a moisture sensor. When the moisture content of the material meets the standard, the electric telescopic rod moves through the connecting rod and the sealing plate to open the discharge port and allow the dried material to be discharged.

[0014] Preferably, the limiting component includes a first limiting member, two second limiting members, and multiple connecting plates. The first limiting member is located between the two second limiting members, and the multiple connecting plates are arranged in a circular array on the fixed box and located inside the rotating cylinder. The first limiting member and the second limiting members are both mounted on the connecting plates.

[0015] Preferably, the limiting member includes a ring and a plurality of protrusions mounted on the ring, the plurality of protrusions being mounted in a ring array on the outer side of the ring.

[0016] Preferably, the limiting member two includes a ring two and a plurality of protrusions two mounted on the ring two. The number of protrusions two is the same as the number of protrusions one. Both the ring one and the ring two are mounted on the connecting plate, and the protrusions one and the protrusions two are arranged alternately.

[0017] Preferably, the adjustment assembly includes a support frame installed between two partitions, a push rod slidably connected to the support frame, a limiting rod installed at the bottom of the push rod, and a fixing plate installed at the top of the push rod. The bottom of the push rod is located inside the rotating cylinder, the limiting rod can contact the protrusion, and the fixing plate is located inside the support frame.

[0018] During the rotation of the rotating cylinder, the support frame 1 rotates, and the support frame 1 drives the push rod 1 to rotate. During the rotation of the push rod 1, it can continuously push the limiting rod 1 through multiple protrusions, thereby causing the fixed plate to move back and forth in the support frame 1.

[0019] Preferably, the second adjustment component includes a second support frame installed between two adjacent partitions, a second push rod slidably connected in the second support frame, a second limiting rod installed at the bottom of the second push rod, a connecting plate installed at the top of the second push rod, and two pressing components rotatably connected in the second support frame. The bottom end of the second push rod is located inside the rotating cylinder, and the connecting plate is located inside the second support frame.

[0020] Preferably, the extrusion component includes a pressure plate and a rotating shaft. The rotating shaft is rotatably connected to the inner wall of the second support frame, the pressure plate is installed on the outer side of the rotating shaft, and the connecting plate has a groove for accommodating the pressure plate.

[0021] During the rotation of the rotating cylinder, the second support frame rotates, and the second support frame rotates, which in turn drives the second push rod to rotate. During the rotation of the second push rod, multiple protrusions push the second limit rod, thereby causing the connecting plate to move back and forth in the second support frame. When the connecting plate moves, it can push the pressure plate to rotate around the rotating shaft.

[0022] Preferably, the material turning assembly includes a rotating rod, a fixed rod, two fixed plates, and two rows of turning plates. The rotating rod is rotatably connected to a support frame. The two rows of turning plates are respectively installed on both sides of the rotating rod. The turning plates on the rotating rods of the two material turning assemblies are staggered. The fixed rod is installed in the middle of one side of the rotating rod. The fixed rods on the two rotating rods are staggered. The fixed rod is located inside the support frame and contacts the top of the fixed plate. The two fixed plates are respectively installed on the outer sides of both ends of the rotating rod. The top of the fixed plate contacts the bottom of the pressure plate.

[0023] When the fixed plate moves upward, it can drive the rotating rod on the fixed rod to rotate, thereby driving the flipping plate to rotate between the two partitions. At the same time, the rotating rod pushes the pressure plate through the fixed plate, causing the pressure plate to squeeze the connecting plate, thereby driving the connecting plate to move downward. When the connecting plate moves upward, the connecting plate presses down on the fixed plate through the pressure plate, thereby driving the flipping plate on the rotating rod to rotate in the opposite direction. At the same time, the fixed rod on the rotating rod can push the fixed plate downward.

[0024] Preferably, the feeding mechanism includes a material cylinder, a material distribution plate, and two rows of elastic elements. The material cylinder is mounted on a fixed box, the material distribution plate is disposed inside the material cylinder, the material distribution plate is inverted V-shaped, and the two rows of elastic elements are respectively disposed on the material distribution plate.

[0025] The beneficial effects of the present invention by adopting the above technical solution are as follows: the material enters the receiving cavity at an inclination through the guide cavity and falls between multiple baffles on the rotating cylinder, thereby dividing the material into multiple portions. When the moisture content of the material at the discharge port is not up to standard, the material's gravity pushes the baffles and rotating cylinder to rotate, thereby causing the material with the insufficient moisture content to move upward and continue drying. While the rotating cylinder is rotating, it can also transfer other materials to the discharge port, so that the dried material is discharged first, preventing the undried material from blocking the discharge port and causing the dried material to be unable to be discharged. Therefore, it is not necessary to wait for the bottom layer of material to dry before discharging, thereby improving the material discharge efficiency. Attached Figure Description

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] like Figures 1 to 10 As shown, the raw material particle drying equipment of the present invention includes a feeding mechanism 10, a discharging mechanism 20, a control mechanism 30, and a turning mechanism 40. The feeding mechanism 10 is installed on top of the discharging mechanism 20, the control mechanism 30 is installed on one side of the discharging mechanism 20, and the turning mechanism 40 is rotatably disposed inside the discharging mechanism 20. The turning mechanism 40 is capable of dividing the material in the discharging mechanism 20 into multiple portions.

[0043] When drying materials, the control mechanism 30 is activated and hot air is introduced into the turning mechanism 40. The hot air then passes through the turning mechanism 40 into the feeding mechanism 10 and the discharging mechanism 20. The material is then fed into the feeding mechanism 10 and dried by the hot air as it passes through them. The dried material is discharged from the bottom of the discharging mechanism 20. If the material at the bottom is not sufficiently dried, the turning mechanism 40 rotates the under-dried material upwards, allowing it to continue drying while simultaneously transferring the dried material to the bottom for discharge, thus reducing waiting time.

[0044] like Figures 1 to 4 As shown, the feeding mechanism 10 includes a material cylinder 11, a cover plate 12, a connecting hopper 13, a distribution plate 14, elastic elements, and a mounting plate 17. The cover plate 12 is hinged to the top of the material cylinder 11, the connecting hopper 13 is installed on the top of the cover plate 12, and an exhaust pipe is installed on one side of the top of the material cylinder 11. The distribution plate 14 is located inside the material cylinder 11 and directly below the connecting hopper 13, and the distribution plate 14 is inverted V-shaped. There are two rows of elastic elements, which are respectively arranged on the bottom sides of the distribution plate 14. In this embodiment, there are two elastic elements in each row; in other embodiments, there may be three, four, or more elastic elements in each row. There are two mounting plates 17, both of which are fixed to the inner wall of the material cylinder 11. The two rows of elastic elements are respectively arranged on the two mounting plates 17.

[0045] The elastic element includes a slide rod 15, a spring 16, and a limiting plate 18. The top end of the slide rod 15 is mounted on the bottom of the distribution plate 14, and the top end of the slide rod 15 passes through the mounting plate 17 and extends to the outside of the mounting plate 17. The limiting plate 18 is mounted on the bottom end of the slide rod 15 to prevent the slide rod 15 from disengaging from the limiting plate 18. The spring 16 is sleeved on the outside of the slide rod 15 and is installed between the distribution plate 14 and the mounting plate 17.

[0046] When the material enters the material cylinder 11 through the connecting hopper 13, the material distribution plate 14 comes into contact with the material first. At this time, the material distribution plate 14 vibrates up and down under the action of the spring 16, so that the material is more dispersed when it falls in the material cylinder 11, making it easier for the material to be dried better.

[0047] like Figures 1 to 2 As shown, the discharge mechanism 20 includes a guide assembly 21, a sealing assembly 22, a discharge hopper 23, and support legs 24. The top of the guide assembly 21 is installed at the bottom of the material cylinder 11, the top of the sealing assembly 22 is installed at the bottom of the guide assembly 21, and the top of the discharge hopper 23 is installed at the bottom of the sealing assembly 22. There are four support legs 24, which are respectively installed at the four corners of the bottom of the sealing assembly 22.

[0048] After the material passes through the material cylinder 11, it enters the guide component 21 and is transferred to the bottom of the guide component 21 by the turning mechanism 40. Then the sealing component 22 is opened, allowing the material to pass through the sealing component 22 and be discharged through the discharge hopper 23.

[0049] like Figure 2 and Figure 5 As shown, the guiding assembly 21 includes a fixed box 211, a receiving cavity 214, and a guiding cavity 215. The top of the fixed box 211 has a connecting port 212, which communicates with the material cylinder 11. The bottom of the fixed box 211 has a discharge port 213 for material discharge. A moisture sensor (not shown) is installed at the discharge port 213 to detect the moisture content of the bottom layer of material. The receiving cavity 214 is located inside the lower part of the fixed box 211 and communicates with the discharge port 213. The receiving cavity 214 is circular in shape, and the tilting mechanism 40 is rotatably disposed within the receiving cavity 214. The guiding cavity 215 is located inside the upper part of the fixed box 211. The bottom of the guiding cavity 215 communicates with the receiving cavity 214, and the top of the guiding cavity 215 communicates with the connecting port 212. One side of the inner wall of the guiding cavity 215 is inclined to guide the material to tilt into the receiving cavity 214.

[0050] After passing through the material cylinder 11, the material enters the guide cavity 215 through the connecting port 212. Guided by the guide cavity 215, the material then enters the receiving cavity 214. Once in the receiving cavity 214, the material is transferred to the discharge port 213 by the turning mechanism 40. At this point, a moisture sensor detects the moisture content of the material at the discharge port 213. When the moisture content meets the standard, the sealing component 22 opens, allowing the dried material to be discharged through the discharge port 213. When the moisture content does not meet the standard, the turning mechanism 40 rotates, causing the material with the insufficient moisture content to move upwards for continued drying. Simultaneously, it transfers other material to the discharge port 213 for further monitoring.

[0051] Continue to refer to Figure 2 and Figure 5 As shown, the sealing assembly 22 includes a fixed frame 221, an electric telescopic rod 222, a connecting rod 223, and a sealing plate 224. The fixed frame 221 is installed between the fixed box 211 and the discharge hopper 23. The fixed end of the electric telescopic rod 222 is installed on one side of the fixed frame 221, and the movable end of the electric telescopic rod 222 passes through one side of the fixed frame 221 and extends into the interior of the fixed frame 221. The electric telescopic rod 222 is electrically connected to a moisture sensor, and the electric telescopic rod 222 is activated when the moisture content of the material reaches the standard. One end of the connecting rod 223 is installed on the movable end of the electric telescopic rod 222, and the sealing plate 224 is installed on the other end of the connecting rod 223. In the initial state, the sealing plate 224 is located at the bottom of the discharge port 213 to close the discharge port 213.

[0052] When the moisture content of the material reaches the standard, the electric telescopic rod 222 is activated. At this time, the electric telescopic rod 222 drives the sealing plate 224 to be misaligned with the discharge port 213 through the connecting rod 223, thereby opening the discharge port 213 so that the material can be discharged from the fixed box 211 through the discharge port 213.

[0053] like Figures 1 to 2 and Figure 5 As shown, the control mechanism 30 includes a control box 31, a blower 32, and a hot air duct 33. The control box 31 is installed on one side of the fixed box 211, and a heating element is provided in the control box 31. In this embodiment, the heating element is an electric heating tube. One end of the blower 32 is installed on one side of the control box 31, the top end of the hot air duct 33 is installed on the bottom of the control box 31, and the bottom end of the hot air duct 33 is installed on the fixed box 211. Both the blower 32 and the hot air duct 33 are connected to the heating element on the control box 31.

[0054] When drying materials, blower 32 blows air into heating element in control box 31. After being heated by heating element, air is sent into fixed box 211 through hot air pipe 33 to dry materials.

[0055] like Figures 5 to 6 As shown, the material-turning mechanism 40 includes a rotating drum assembly 41, a limiting assembly 42, an adjusting assembly 43, an adjusting assembly 44, and a material-turning assembly 45. The rotating drum assembly 41 is rotatably disposed in the receiving cavity 214 of the fixed box 211, and the limiting assembly 42 is installed on the inner wall of the fixed box 211 and located inside the rotating drum assembly 41. There are multiple adjusting assemblies 43, which are arranged in a circular array around the axis of the rotating drum assembly 41 on the outside of the rotating drum assembly 41. There are multiple sets of adjusting assemblies 44 and material-turning assemblies 45, which are also arranged in a circular array around the axis of the rotating drum assembly 41 on the outside of the rotating drum assembly 41.

[0056] like Figures 5 to 7As shown, the rotating drum assembly 41 includes a rotating drum 411, a partition plate 412, a connecting shaft 413, and a locking member 414. The rotating drum 411 is rotatably connected to the receiving cavity 214 of the fixed box 211, and one end of the hot air pipe 33 is connected to one end of the rotating drum 411. One end of the connecting shaft 413 is installed at the other end of the rotating drum 411, and the other end of the connecting shaft 413 passes through the fixed box 211 and extends to the outside of the fixed box 211. The locking member 414 is sleeved on the other end of the connecting shaft 413 and fixed to the fixed box 211. The locking member 414 is electrically connected to a moisture sensor. In this embodiment, the locking member 414 is an electric chuck. In other embodiments, the connecting shaft 413 can also be connected to a motor, and the motor is electrically connected to the moisture sensor. When the moisture sensor detects that the moisture content of the material is below the standard, the motor drives the rotating drum 411 to rotate through the connecting shaft 413.

[0057] There are multiple partitions 412, which are arranged in a circular array around the axis of the rotating cylinder 411 on the outside of the rotating cylinder 411. Both the rotating cylinder 411 and the partitions 412 have holes for hot air to pass through, allowing the hot air to dry the material. The multiple partitions 412 divide the receiving cavity 214 in the fixed box 211 into multiple spaces, thus dividing the material into multiple portions. Multiple adjusting components 43, multiple adjusting components 44, and multiple material turning components 45 are located in multiple spaces of the receiving cavity 214.

[0058] Hot air enters the rotating cylinder 411 through the hot air pipe 33. After passing through the rotating cylinder 411, the hot air enters the receiving cavity 214. The hot air entering the receiving cavity 214 enters the material cylinder 11 through the guide cavity 215, and finally exits from the exhaust pipe on the material cylinder 11.

[0059] When the moisture sensor detects the material, the locking member 414 locks the connecting shaft 413 to prevent the rotating drum 411 from rotating. When the moisture content of the material reaches the standard, the locking member 414 unlocks. At this time, the force of the material falling can push the partition 412, thereby driving the rotating drum 411 to rotate. During the rotation of the rotating drum 411, the partition 412 drives the material with the unmet moisture content to rotate upward, so that the material continues to be dried.

[0060] like Figures 6 to 8 As shown, the limiting assembly 42 includes a limiting member one, a limiting member two, and a connecting plate 425. There are two limiting members two, which are respectively disposed on both sides of the limiting member one. There are three connecting plates 425, which are arranged in a circular array inside the rotating cylinder 411. The limiting members one and two are both mounted on the three connecting plates 425, and one end of the connecting plate 425 extends out of the rotating cylinder 411 and is mounted on one side of the inner wall of the fixed box 211.

[0061] The limiting component includes a ring 421 and a protrusion 422. There are multiple protrusions 422, which are arranged in a ring array on the outside of the ring 421.

[0062] The second limiting component includes a second ring 423 and a second protrusion 424 mounted on the second ring 423. The first ring 421 and the second ring 423 are coaxially arranged with the rotating cylinder 411, and the number of second protrusions 424 is the same as the number of first protrusions 422. Both the first ring 421 and the second ring 423 are mounted on the connecting plate 425. The first protrusions 422 on the first ring 421 and the second protrusions 424 on the second ring 423 are staggered.

[0063] like Figures 6 to 9 As shown, the adjusting assembly 43 includes a support frame 431, a push rod 432, a limiting rod 433, and a fixing plate 434. The support frame 431 is installed between two adjacent partitions 412, and its bottom is arc-shaped to prevent material residue from remaining on it. Each set of adjusting assemblies 44 consists of two components, each positioned on one side of the support frame 431. Each set of tilting assemblies 45 consists of two components, both rotatably connected to the support frame 431. The top end of the push rod 432 is located inside the support frame 431, and its bottom end is located inside the rotating cylinder 411. The push rod 432 is slidably connected to the support frame 431. The limiting rod 433 is installed at the bottom end of the push rod 432 and can contact the protrusion 422. The fixing plate 434 is installed at the top of the push rod 432 and is located inside the support frame 431.

[0064] When the rotating drum 411 rotates, it drives the support frame 431 and the push rod 432 to rotate via the partition 412. At this time, the protrusion 422 can lift the limiting rod 433. As the limiting rod 433 moves upward, it can drive the fixed plate 434 on the push rod 432 to move upward. As the fixed plate 434 moves upward, it can push the two turning components 45 to rotate, so as to turn the material between the two partitions 412, thereby improving the drying efficiency of the material.

[0065] like Figures 6 to 10As shown, the adjusting assembly 2 44 includes a support frame 2 441, a push rod 2 442, a limiting rod 2 443, a connecting plate 444, and an extrusion component. The support frame 2 441 is installed between two adjacent partitions 412, and the support frame 1 431 has the same structure as the support frame 2 441. The top end of the push rod 2 442 is located inside the support frame 2 441, and the bottom end of the push rod 2 442 is located inside the rotating cylinder 411, with the push rod 2 442 slidably connected to the rotating cylinder 411. The limiting rod 2 443 is installed at the bottom end of the push rod 2 442 and can contact the protrusion 2 424. The connecting plate 444 is installed at the top end of the push rod 2 442 and is located inside the support frame 2 441. There are two extrusion components, symmetrically arranged on both sides of the support frame 2 441 along the axis of the push rod 2 442.

[0066] like Figures 9 to 10 As shown, the extrusion component includes a pressure plate 445 and a rotating shaft 446. The rotating shaft 446 is rotatably connected to the inner wall of the support frame 441, the pressure plate 445 is installed on the outer side of the rotating shaft 446, and the top of the connecting plate 444 is provided with a groove to accommodate the pressure plate 445.

[0067] During the rotation of the rotating cylinder 411, the rotating cylinder 411 drives the second support frame 441 and the second push rod 442 to rotate. At this time, under the action of the second protrusion 424, the second limit rod 443 can be lifted up. During the upward movement of the second limit rod 443, the connecting plate 444 on the second limit rod 443 can be driven to move upward, so as to push the two turning components 45 to rotate in opposite directions.

[0068] like Figure 6 and Figures 8 to 10 As shown, the material-turning assembly 45 includes a rotating rod 451, a turning plate 452, a fixing rod 453, and a fixing plate 454. The rotating rod 451 is rotatably connected to the first support frame 431, and its two ends are rotatably connected to the inner walls of the two second support frames 441, respectively. There are two rows of turning plates 452, which are respectively installed on both sides of the rotating rod 451, and the turning plates 452 on the two rotating rods 451 are staggered. The fixing rod 453 is installed in the middle of one side of the rotating rod 451, and the fixing rods 453 on the two rotating rods 451 are staggered. The fixing rod 453 is located inside the first support frame 431 and contacts the top of the fixing plate 434. There are two fixing plates 454, which are respectively installed on the outer sides of both ends of the rotating rod 451, and the top of the fixing plate 454 contacts the bottom of the pressure plate 445.

[0069] When protrusion 422 lifts limit rod 433, limit rod 433 pushes push rod 432 upward. Push rod 432 pushes fixed rod 453 upward through fixed plate 434. At the same time, fixed rod 453 drives tilting plate 452 to rotate through rotating rod 451, thus tilting the material between the two partitions 412. During the upward rotation of fixed rod 453, fixed plate 454 follows rotating rod 451 upward, thereby pushing pressure plate 445 to rotate around rotating shaft 446. During the rotation, pressure plate 445 pushes connecting plate 444 downward. At the same time, connecting plate 444 pushes limit rod 443 downward through push rod 442, so that limit rod 443 is located between the two protrusions 424. Conversely, when the second protrusion 424 lifts the second limiting rod 443, the connecting plate 444 can drive the rotating rod 451 on the fixed plate 454 to rotate in the opposite direction through the pressure plate 445. At the same time, the fixed rod 453 on the rotating rod 451 can press down the fixed plate 434 to push the first limiting rod 433 into the space between the first protrusion 422, thereby enabling the turning plate 452 to rotate back and forth around the rotating rod 451 between the partition plates 412 to turn the material back and forth.

[0070] Working principle: When drying materials, the materials enter the material cylinder 11 through the connecting hopper 13. When the materials enter the material cylinder 11, the separating plate 14 contacts the materials first, thus making the materials more dispersed when falling in the material cylinder 11. After passing through the material cylinder 11, the materials pass through the connecting port 212, the guide cavity 215, and then fall between the two partitions 412 on the rotating cylinder 411. At this time, the partitions 412 can rotate around the rotating cylinder 411 under the action of the material's own weight, thereby driving the materials to the discharge port 213. At this time, the moisture sensor detects the material, and the rotating cylinder 411 stops rotating under the action of the locking part 414. When the moisture content of the material reaches the standard, the electric telescopic rod 222 drives the sealing plate 224 to be misaligned with the discharge port 213 through the connecting rod 223, thereby opening the discharge port 213 so that the materials can be discharged from the fixed box 211 through the discharge port 213.

[0071] When the moisture content is below the standard, the electric telescopic rod 222 does not start, and the locking part 414 unlocks. At this time, under the action of the material's gravity, the rotating drum 411 continues to rotate, causing the material between the other two partitions 412 to be transferred to the discharge port 213. This allows the material with the standard moisture content to be discharged first, while the material with the lower moisture content continues to dry, preventing the undried material from blocking the discharge port 213 and preventing the dried material from being discharged.

[0072] During the rotation of the rotating cylinder 411, the rotating cylinder 411 drives the support frame 431 and the support frame 441 to rotate synchronously through the partition plate 412. At the same time, the push rod 432 and the push rod 442 rotate with the support frame 431 and the support frame 441, respectively. During the rotation of the push rod 432 and the push rod 442, the protrusion 422 and the protrusion 424 respectively push the push rod 432 and the push rod 442 in turn through the limiting rod 433 and the limiting rod 443, respectively.

[0073] When the limiting rod 433 is lifted, the fixed plate 434 on the push rod 432 moves upward. During this upward movement, the fixed plate 434 pushes the fixed rod 453 to rotate upward. Simultaneously, the fixed rod 453 drives the tilting plate 452 to rotate via the rotating rod 451, thus tilting the material between the two partitions 412. As the fixed rod 453 rotates upward, the fixed plate 454 follows the rotating rod 451, thereby pushing the pressure plate 445 to rotate around the rotating shaft 446. During this rotation, the pressure plate 445 pushes the connecting plate 444 downward. The connecting plate 444, through the push rod 442, pushes the limiting rod 443 downward, positioning the limiting rod 443 between the two protrusions 424.

[0074] When the second limiting rod 443 is lifted, the connecting plate 444 can drive the rotating rod 451 on the fixed plate 454 to rotate in the opposite direction through the pressure plate 445. At the same time, the fixed rod 453 on the rotating rod 451 can press down the fixed plate 434 to push the first limiting rod 433 into the space between the first protrusion 422, so that the turning plate 452 can rotate back and forth around the rotating rod 451 between the two partitions 412 to turn the material back and forth.
