Description

Technical Field

[0001] This utility model relates to the field of renewable resource recycling technology, and more specifically, to a material dispensing device. Background Technology

[0002] For waste sorting and recycling, conveyor belts are typically used as the main sorting device. Through a scientific and effective sorting and recycling system, efficient resource recycling can be achieved, transforming waste into renewable resources. Currently, conveyor belts use gate-type sorting valves to divert materials. Specifically, cylinders are vertically arranged to drive the valves to move up and down. When the valve descends and contacts the surface of the running conveyor belt, the material carried on the belt is blocked by the valve and guided to the target hopper along the angle formed between the valve and the belt.

[0003] However, in actual operation, some material cannot be completely guided into the designated bin along the valve direction, but instead remains and accumulates on the belt or valve surface. When the cylinder drives the valve to rise, this residual material continues to move with the belt and enters the next bin, causing material mixing. This mixing not only reduces the purity of the sorted material, but also affects the overall sorting efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a material sorting device that can improve the purity of the sorted materials and the overall sorting efficiency.

[0005] The embodiments of this utility model are implemented as follows:

[0009] The material dispensing valve is rotatably disposed on one side of the material dispensing and conveying mechanism, and the material dispensing valve has an open state and a closed state;

[0010] When the material distribution valve is in the open state, it is used to guide the material on the material distribution conveying mechanism into the silo; during the process of the material distribution valve switching from the open state to the closed state, it is used to sweep the material accumulated on the material distribution valve and the material distribution conveying mechanism into the silo.

[0011] In an optional embodiment, the material distribution device further includes a material guide trough, which is disposed on one side of the material distribution and conveying mechanism.

[0013] In an optional embodiment, the dispensing valve includes a rotating part and a dispensing part. One end of the rotating part is hinged to the driving member, and the other end of the rotating part is rotatably connected to the dispensing conveying mechanism. The end of the dispensing part near the driving member is fixedly connected to the rotating part.

[0014] In an optional embodiment, a mounting member is provided on one side of the material conveying mechanism, the fixed end of the driving member is hinged to the mounting member, and the movable end of the driving member is hinged to the rotating part.

[0015] In an optional embodiment, the material dispensing device further includes a speed regulator disposed on the drive member; and / or,

[0016] The material dispensing device further includes a proximity switch, which is disposed on the driving component; and / or,

[0017] The material distribution device also includes a detection switch, which is located on one side of the material distribution and conveying mechanism.

[0018] In an optional embodiment, the material distribution and conveying mechanism includes a first support frame, a second support frame, and a conveyor belt, wherein the first support frame and the second support frame are respectively disposed on opposite sides of the conveyor belt;

[0019] The hopper is located on the side of the first support frame away from the second support frame. The dispensing valve is rotatably mounted on the first support frame. When the dispensing valve is in the open state, the dispensing valve abuts against the second support frame.

[0020] In an optional embodiment, the dispensing device further includes a purger disposed on the second support frame. The purger is used to purge material accumulated on the dispensing valve when the dispensing valve is in the open state; and / or,

[0021] The material dispensing device further includes a first guide plate, which is disposed on the second support frame and is used to cooperate with the material dispensing valve; and / or,

[0022] The material distribution device further includes a second guide plate, which is disposed at one end of the material distribution valve near the first support frame.

[0023] In an optional embodiment, there are multiple hoppers and multiple distributing valves. The multiple hoppers are arranged sequentially along the extension direction of the distributing conveying mechanism, and the multiple distributing valves are arranged one-to-one with the multiple hoppers.

[0024] In an optional embodiment, the material distribution device further includes a conveying platform, and the material distribution and conveying mechanism is disposed on the conveying platform.

[0025] The beneficial effects of this utility model embodiment include:

[0026] The material distribution device rotatably mounts a distribution valve on the material distribution conveyor mechanism. This allows the valve to intercept material on the conveyor belt, and through the combined guiding action of the valve and the conveying action of the mechanism, guide the material into the hopper. Specifically, when the valve is open, its extension direction forms an angle with the conveying direction of the conveyor mechanism. During transport, the material is intercepted by the valve. As the conveyor mechanism continuously transports the material, it moves along its direction. When the material encounters the valve, it is gradually guided into the hopper along the valve's extension direction. Furthermore, because the valve rotates relative to the conveyor mechanism, when it closes, it further sweeps material accumulated on the valve into the hopper, reducing the probability of material residue accumulating on the valve surface or the conveyor mechanism, thus improving the purity of the sorted material and overall sorting efficiency.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] As described in the background section, current material distribution belt conveyors use gate-type distribution valves to divert materials. However, in actual operation, some material cannot be completely guided into the designated bin along the valve direction, but instead remains and accumulates on the belt or valve surface. When the cylinder drives the valve to rise, this residual material continues to move with the belt and enters the next bin, causing material mixing. This mixing not only reduces the purity of the sorted material but also affects the overall sorting efficiency.

[0045] Based on this, please refer to Figures 1-9 This utility model provides a material distribution device 100 and a valve anti-jamming method, which can effectively improve the aforementioned technical problems, that is, it can improve the purity of the sorted material 200 and the overall sorting efficiency. The material distribution device 100 and the valve anti-jamming method will be described in detail below.

[0046] Please refer to Figures 1-3 , Figure 1 This is a first-view structural schematic diagram of the material dispensing device 100 provided in this embodiment. Figure 2 This is a structural schematic diagram of the material dispensing device 100 provided in this embodiment from a second perspective. Figure 3 This is a partial structural schematic diagram of the material dispensing device 100 provided in this embodiment. (Combined with...) Figures 1-3 The material distribution device 100 includes a material distribution and conveying mechanism 10, a hopper 20, and a material distribution valve 30.

[0047] Specifically, the hopper 20 is located on one side of the material distribution and conveying mechanism 10 and is used to receive the material 200 on the material distribution and conveying mechanism 10. The material distribution valve 30 is rotatably located on one side of the material distribution and conveying mechanism 10 and has an open state and a closed state. When the material distribution valve 30 is in the open state, it is used to guide the material 200 on the material distribution and conveying mechanism 10 into the hopper 20; when the material distribution valve 30 switches from the open state to the closed state, it is used to sweep the material 200 accumulated on the material distribution valve 30 and the material distribution and conveying mechanism 10 into the hopper 20.

[0048] It should be pointed out that, Figure 2 and Figure 3 The X direction shown is the direction in which the material distribution and conveying mechanism 10 conveys the material 200. That is, when the material distribution valve 30 is open, its extension direction forms a certain angle with the X direction. During conveying, the material 200 will be intercepted by the material distribution valve 30. Because the material distribution and conveying mechanism 10 continuously operates to convey the material 200, the material 200 always moves along the X direction. When the material 200 encounters the obstruction of the material distribution valve 30, it will gradually be guided into the hopper 20 along the extension direction of the material distribution valve 30. It is easy to understand that since the material distribution valve 30 rotates relative to the material distribution and conveying mechanism 10, during the closing process, it can further sweep the material 200 accumulated on the material distribution valve 30 into the hopper 20, thereby reducing the probability of material 200 remaining on the valve surface or the material distribution and conveying mechanism 10, improving the purity of the sorted material 200 and the overall sorting efficiency.

[0049] In order to better guide the material 200 and prevent the material 200 from falling outside the hopper 20 during the material guiding and sweeping process, the material distribution valve 30 in this embodiment also includes a material guide trough 70. The material guide trough 70 is disposed on one side of the material distribution conveying mechanism 10. The material distribution valve 30 is located at the inlet of the material guide trough 70 and is used to guide the material 200 on the material distribution conveying mechanism 10 into the inlet of the material guide trough 70. The outlet of the material guide trough 70 is correspondingly disposed to the hopper 20.

[0050] Furthermore, to facilitate control of the rotation of the distributing valve 30 and achieve precise control of its opening and closing angles, thereby improving sorting efficiency and equipment automation, in this embodiment, the distributing device 100 also includes a drive component 40. The drive component 40 is located on one side of the distributing conveying mechanism 10 and is connected to the distributing valve 30. Of course, in other embodiments, the drive component 40 may not be provided, and the distributing valve 30 may be manually rotated to guide the material 200 and guide residual material 200 into the hopper 20.

[0051] It should be noted that in this embodiment, the driving component 40 is specifically a cylinder. Of course, in other embodiments, the driving component 40 may also be a hydraulic cylinder, an electric push rod, or other driving structures.

[0052] Please continue to combine Figure 2 and Figure 3 Specifically, the material distribution and conveying mechanism 10 includes a first support frame 11, a second support frame 12, and a conveyor belt 13. The first support frame 11 and the second support frame 12 are respectively disposed on opposite sides of the conveyor belt 13. The hopper 20 is located on the side of the first support frame 11 away from the second support frame 12. The material distribution valve 30 is rotatably disposed on the first support frame 11, and the driving component 40 is disposed on the first support frame 11. When the material distribution valve 30 is in the open state, the material distribution valve 30 abuts against the second support frame 12.

[0053] It should be noted that in existing technologies, valves move up and down, with their entire weight borne by a cylinder. This requires a larger cylinder, increasing equipment costs. Especially when the equipment is idle for extended periods, cylinder leaks can occur, causing the valve to press completely against the conveyor belt under its own weight, making it difficult to start the conveyor and affecting normal operation. In this embodiment, the rotary motion of the distributing valve 30, when closed, allows it to rotate back onto the first support frame 11, preventing contact with the conveyor belt 13 and other equipment. This ensures the normal operation of the conveyor belt 13 and other components. Simultaneously, the first support frame 11 primarily bears the weight of the distributing valve 30, reducing the driving force of the drive component 40 and eliminating the need for a larger drive structure, thus lowering equipment costs.

[0054] Additionally, it should be noted that the "open state" mentioned above can be understood as the state when the material distribution valve 30 is rotated to its maximum angle, that is, when the end of the material distribution valve 30 away from the drive component 40 is in contact with the second support frame 12. In this state, it ensures that all the material 200 on the conveyor belt 13 can be intercepted and guided by the material distribution valve 30. The "closed state" mentioned above can be understood as the state when the material distribution valve 30 is rotated back to the first support frame 11. In this state, the material distribution valve 30 is not in contact with the conveyor belt 13 and is not located above the conveyor belt 13, ensuring the normal flow of the material 200 on the conveyor belt 13.

[0055] Further, please refer to Figure 4 , Figure 4 for Figure 3 A magnified view of a section at point A, combined with Figure 3 and Figure 4 The dispensing valve 30 includes a rotating part 31 and a dispensing part 32. One end of the rotating part 31 is hinged to the driving member 40, and the other end of the rotating part 31 is rotatably connected to the dispensing conveying mechanism 10. Specifically, in this embodiment, the other end of the rotating part 31 is rotatably connected to the first support frame 11. The end of the dispensing part 32 near the driving member 40 is fixedly connected to the rotating part 31. When the dispensing valve 30 is in the open state, the end of the dispensing part 32 away from the rotating part 31 abuts against the second support frame 12.

[0056] like Figure 4 As shown, the method of driving the rotating part 31 to rotate relative to the material distributing and conveying mechanism 10 via the driving component 40, thereby driving the distributing part 32 to rotate, can be understood as utilizing the lever principle. That is, the driving component 40 applies power, the rotating part 31 acts as the power arm, and the connection between the rotating part 31 and the first support frame 11 of the material distributing and conveying mechanism 10 is the fulcrum. The driving component 40 applies a force to the end of the rotating part 31 away from the first support frame 11, thereby facilitating the rotation of the distributing part 32 located at one end of the first support frame 11. It is easy to understand that since the distributing part 32 encounters less resistance during the opening of the distributing valve 30, the driving component 40 can apply a smaller driving force to drive the distributing part 32 to rotate. This eliminates the need for a model with a large driving force, allowing for a smaller driving structure to be selected for the driving component 40, thereby reducing equipment costs and making the overall structure of the distributing device 100 lighter.

[0057] In order to better install and disassemble the drive component 40, a mounting component 111 is provided on one side of the material conveying mechanism 10. Specifically, in this embodiment, the mounting component 111 is located on the side of the first support frame 11 away from the second support frame 12; the fixed end of the drive component 40 is hinged to the mounting component 111, and the movable end of the drive component 40 is hinged to the rotating part 31.

[0058] like Figure 4 As shown, by setting the drive component 40 on the side of the first support frame 11 away from the second support frame 12, the drive component 40 will not interfere with other structures of the material distribution device 100 during the driving process, which can improve the installation stability of the drive component 40 and make the process of driving the material distribution valve 30 smoother; at the same time, it is easy to disassemble and install, which can improve maintenance and installation efficiency.

[0059] Please refer to Figure 5 , Figure 5 This is a partial structural diagram of the first working condition of the material sorting device 100 provided in this embodiment. In the actual process of sorting materials 200, there may be material 200 accumulating at the contact point between the material sorting valve 30 and the second support frame 12, making it difficult for the material 200 at this point to be guided to the middle area of ​​the material sorting valve 30 along the extension direction of the material sorting valve 30 under the action of the conveyor belt 13.

[0060] Therefore, in order to better guide the material 200 accumulated at the junction of the distributing valve 30 and the second support frame 12, please refer to... Figure 6 , Figure 6 for Figure 3 A magnified view of a section at point B, combined with... Figure 3 and Figure 6 The material distribution device 100 also includes a first guide plate 61, which is disposed on the second support frame 12 and is used to cooperate with the material distribution valve 30. The first guide plate 61 is inclined and also has a guiding function. When the material distribution valve 30 is in the open state, it can work with the valve to guide the material 200, thereby improving the sorting efficiency.

[0061] Furthermore, in order to improve the flow guiding effect, when the material distribution valve 30 is in the open state, the first guide plate 61 is parallel to the material distribution valve 30.

[0062] Please refer to Figure 7 , Figure 7 This is a partial structural schematic diagram of the first working condition of the material dispensing device 100 provided in this embodiment, combined with... Figures 5-7 It should be noted that in the actual sorting process, there may be a situation where there is a large amount of material 200, and there may be a lot of material 200 accumulating at the contact point between the material distribution valve 30 and the second support frame 12 or between the material distribution valve 30 and the first guide plate 61. As a result, when the material distribution valve 30 is closed, some residual material 200 may easily get stuck between the material distribution valve 30 and the protective plate of the second support frame 12, or between the material distribution valve 30 and the guide trough 70, making it impossible for the material distribution valve 30 to close normally, affecting the sorting efficiency and normal operation of the equipment.

[0063] Therefore, in order to further reduce the probability of material 200 remaining on the valve surface or the material conveying mechanism 10, and to reduce the probability of jamming and material jamming, in this embodiment, the material dispensing device 100 also includes a blower 50, which is disposed on the second support frame 12. The blower 50 is used to blow away the material 200 accumulated on the material dispensing valve 30 when the material dispensing valve 30 is in the open state.

[0064] To improve the purging effect and further enhance sorting efficiency and the purity of the sorted material 200, when the distribution valve 30 is open, the purger 50 is set parallel to the distribution valve 30. That is, the purging direction of the purger 50 is the extension direction of the distribution valve 30, which can better blow the material 200 along the extension direction of the distribution valve 30 to the middle area of ​​the distribution valve 30 or the area near the hopper 20, thereby ensuring that the material 200 is better swept into the hopper 20 when the distribution valve 30 is closed.

[0065] Combination Figure 6 In this embodiment, the purger 50 is located on the side of the first guide plate 61 away from the material distribution valve 30, thereby further improving the purging effect and increasing the sorting efficiency.

[0066] Please continue to combine Figure 4 To prevent the end of the dispensing valve 30 near the drive component 40 from interfering with the guide trough 70 or the hopper 20 during the closing process, and to prevent material 200 from getting stuck between the dispensing valve 30 and the guide trough 70 or the hopper 20, in this embodiment, the dispensing device 100 further includes a second guide plate 62, which is disposed at the end of the dispensing valve 30 near the first support frame 11. The second guide plate 62 also has a guiding function, which can facilitate the introduction of material 200 into the guide trough 70 or the hopper 20, thereby ensuring the normal closing of the dispensing valve 30 and improving the sorting efficiency.

[0067] Furthermore, in order to detect whether the dispensing valve 30 is closed in place, in this embodiment, the dispensing device 100 also includes a proximity switch, which is disposed on the drive member 40. Of course, in some embodiments, the valve closure status can also be detected by a detection switch. For example, in other embodiments, the dispensing device 100 also includes a detection switch, which is disposed on one side of the dispensing conveying mechanism 10. Specifically, the detection switch is disposed on the first support frame 11.

[0068] Please continue to combine Figures 1-3The material bins 20 and the distributing valves 30 are multiple in number. Multiple material bins 20 are arranged sequentially along the extension direction of the distributing conveyor mechanism 10, and multiple distributing valves 30 are arranged one-to-one with multiple material bins 20, which can further improve sorting efficiency and save equipment installation space. Of course, in this embodiment, the corresponding number of drive components 40, blowers 50, first guide plates 61, second guide plates 62, and guide troughs 70 are also multiple.

[0069] In addition, combined Figure 1 In order to facilitate the installation of the material distribution and conveying mechanism 10, in this embodiment, the material distribution device 100 also includes a conveying platform 80, and the material distribution and conveying mechanism 10 is disposed on the conveying platform 80.

[0070] Please refer to Figure 8 and Figure 9 , Figure 8 This is a partial structural diagram of the third working condition of the material distribution device 100 provided in this embodiment. Figure 9 This is a flowchart of the valve anti-jamming method provided in this embodiment, combined with... Figure 8 and Figure 9 Valve anti-jamming methods include:

[0071] Step S10: Control the material distribution and conveying mechanism 10 to maintain its operating state;

[0072] Step S20: Control the material distribution valve 30 to rotate forward by a first preset angle or for a first preset duration, so that the material distribution valve 30 is in the open state;

[0073] Step S40: Control the material distribution valve 30 to reverse to the second preset angle or the second preset duration; wherein, the second preset angle is less than the first preset angle, and the second preset duration is less than the first preset duration;

[0074] Step S60: Control the material distribution valve 30 to rotate forward by a second preset angle or for a second preset duration, so that the material distribution valve 30 is in the open state;

[0075] Step S70: Control the material distribution valve 30 to reverse the first preset angle or the first preset duration, so that the material distribution valve 30 is in the closed state.

[0076] It should be noted that the first preset angle can be understood as the angle at which the material distribution valve is rotated to its maximum by 30 degrees. Figure 3 The first preset angle θ1 is shown; as shown Figure 8As shown, the second preset angle θ2 is less than the first preset angle, that is, θ2 < θ1. The first preset duration can be understood as the time taken for the material distribution valve 30 to go from closed to fully open, and the second preset duration can be understood as the time taken for the material distribution valve 30 to go from fully open to closed by a certain angle. For example, the first preset duration is T1, and the second preset duration is T2, that is, T2 < T1.

[0077] In other words, during the material sorting process, after the material sorting valve 30 is fully opened for the first time to intercept and guide the material 200, it will not close directly. Instead, it will close at a certain angle first, and then fully open for the second time. This allows the material 200 located at the end of the material sorting valve 30 away from the drive component 40, or the material 200 accumulated between the material sorting valve 30 and the first guide plate 61 in the open state, to move a certain distance towards the hopper 20 along with the material sorting valve 30. Then, when the material sorting valve 30 is fully opened again, this part of the material 200 will be briefly separated from the material sorting valve 30 and continue to move a certain distance in the X direction under the conveying action of the conveyor belt 13, and then come into contact with the material sorting valve 30 again. At this time, this part of the material 200 will not accumulate between the material sorting valve 30 and the first guide plate 61, but will be located near the hopper 20, which may be in the middle area or the lower middle area of ​​the material sorting valve 30, etc. Next, the material distribution valve 30 reverses and closes, sweeping this portion of material 200 into the hopper 20.

[0078] It should be noted that the above-mentioned valve anti-jamming method can be understood as a secondary shaking closing method, which can prevent the material 200 from getting stuck between the valve and the first support frame 11 when the material distribution valve 30 is closed. This solves the problems of door jamming and material jamming, ensures the normal opening and closing of the material distribution valve 30, thereby ensuring the normal operation of the equipment and further improving the sorting efficiency and the purity of the sorted material 200.

[0079] Optionally, when the material distribution valve 30 is closed to half-closed, that is, when the material distribution valve 30 is in a half-closed state, its shaking effect is better, which can improve the subsequent sweeping effect and sorting efficiency. That is, in this embodiment, θ1 = 2θ2. Of course, in other embodiments, θ1 and θ2 can also have other magnitude relationships.

[0080] In actual operation, the rotation angle of the distributing valve 30 is difficult to control. To more easily achieve the state of closing the distributing valve 30 to half, this can be achieved by controlling the duration of forward or reverse rotation of the distributing valve 30, i.e., T1 = 2T2. For example, in this embodiment, the distributing device 100 also includes a speed regulator, which is disposed on the drive component 40.

[0081] To control the material distribution valve 30 to reverse to the second preset angle, so that the material distribution valve 30 is in a half-open or half-closed position, this can be controlled by using a speed regulator to control the rotation time. Specifically, the speed regulator can be controlled to appropriately slow down the movement speed of the drive component 40, and the time from opening to closing of the drive component 40 can be tested. This time can be understood as the first preset duration T1. The half-open duration of the drive component 40 can be set based on half of this time, that is, the half-open duration can be understood as the second preset duration T2. ​​The relationship between the two is T1 = 2T2, thereby achieving the effect of relatively precise control of the drive component 40 to drive the material distribution valve 30 to the half-open position.

[0082] Please continue to combine Figure 9 To further improve sorting efficiency and reduce the probability of material jamming or gate jamming, the valve anti-jamming method further includes the following steps after step S20 and before step S40:

[0083] Step S30: Control the blower 50 to blow away the material 200 accumulated on the dispensing valve 30.

[0084] In other words, when the material distribution valve 30 is fully opened for the first time, the material 200 is first purged by the blower 50, so that most of the material 200 can be in the middle or lower middle area of ​​the material distribution valve 30, thereby further reducing the probability of material jamming during the closing process of the material distribution valve 30.

[0085] Similarly, after step S40 and before step S60, the valve anti-jamming method further includes:

[0086] Step S50: Control the blower 50 to blow away the material 200 accumulated on the dispensing valve 30.

[0087] In other words, when the material distribution valve 30 is fully opened for the second time, the material 200 is first purged by the blower 50, which can further ensure that some of the residual material 200 is in the middle or lower part of the material distribution valve 30, thereby further reducing the probability of material jamming during the closing process of the material distribution valve 30.

[0088] Please continue to combine Figure 9 During the closing process of the distributing valve 30, material jamming may still occur. Therefore, in this embodiment, after step S70, the valve anti-jamming method further includes:

[0089] Step S80: Check whether the material distribution valve 30 is closed properly;

[0090] Step S91: If the material distribution valve 30 is closed, then control the material distribution conveying mechanism 10 to stop operating.

[0091] Step S92: If the material distribution valve 30 is not closed in place, control the material distribution valve 30 to rotate forward by a third preset angle or a third preset duration; wherein, the third preset angle is less than or equal to the first preset angle, and the third preset duration is less than or equal to the first preset duration.

[0092] Step S93: Control the material distribution valve 30 to reverse the third preset angle or the third preset duration, so that the material distribution valve 30 is in the closed state.

[0093] In other words, if the material distribution valve 30 is detected to be fully closed, there is no material jamming, and the machine can be stopped. Of course, if the material distribution valve 30 is detected to be not fully closed, it indicates that material jamming has occurred, and the material distribution valve 30 needs to be further opened to make the material distribution valve 30 vibrate a third time. In this way, the material 200 stuck on the material distribution valve 30 can continue to move a certain distance along the X direction under the conveying action of the conveyor belt 13, and then continue to enter the hopper 20 under the sweeping action of the material distribution valve 30, thereby further improving the sorting efficiency and the purity of the sorted material 200.

[0094] It should be noted that in this embodiment, the material distribution device 100 also includes a controller, which communicates with the drive unit 40, the material distribution and conveying mechanism 10, the blower 50, the speed controller, the detection switch and the proximity switch, thereby ensuring the orderly control of each structure of the entire material distribution device 100 and realizing the function of preventing material jamming in the valve.

[0095] In summary, the embodiments of this utility model provide a material distribution device 100 and a valve anti-jamming method. The material distribution device 100 includes a material distribution conveying mechanism 10, a hopper 20, and a material distribution valve 30. The hopper 20 is disposed on one side of the material distribution conveying mechanism 10 and is used to receive the material 200 on the material distribution conveying mechanism 10. The material distribution valve 30 is rotatably disposed on one side of the material distribution conveying mechanism 10 and has an open state and a closed state. When the material distribution valve 30 is in the open state, it is used to guide the material 200 on the material distribution conveying mechanism 10 into the hopper 20. During the process of switching the material distribution valve 30 from the open state to the closed state, it is used to sweep the material 200 accumulated on the material distribution valve 30 and the material distribution conveying mechanism 10 into the hopper 20.

[0096] The material distribution device 100 rotatably mounts the material distribution valve 30 on the material distribution conveying mechanism 10, allowing the material distribution valve 30 to intercept the material 200 on the conveyor belt 13. With the guiding action of the material distribution valve 30 and the conveying action of the material distribution conveying mechanism 10, the material 200 is guided into the hopper 20. In other words, when the material distribution valve 30 is open, its extension direction forms a certain angle with the conveying direction of the material distribution conveying mechanism 10. During conveying, the material 200 is intercepted by the material distribution valve 30. Because the material distribution conveying mechanism 10 continuously operates and conveys the material 200, the material 200 always moves along the conveying direction of the material distribution conveying mechanism 10. When the material 200 encounters the obstruction of the material distribution valve 30, it will gradually be guided into the hopper 20 along the extension direction of the material distribution valve 30. As is easily understood, since the material distribution valve 30 rotates relative to the material distribution conveying mechanism 10, during the closing process of the material distribution valve 30, it can further sweep the material 200 accumulated on the material distribution valve 30 into the hopper 20, thereby reducing the probability of material 200 remaining on the valve surface or the material distribution conveying mechanism 10, and improving the purity of the sorted material 200 and the overall sorting efficiency.

[0097] The valve anti-jamming method is implemented using the material distribution device 100, which can improve the purity of the sorted material 200 and the overall sorting efficiency. Furthermore, this valve anti-jamming method, through a two-stage shaking closing mechanism—first fully opening the material distribution valve 30, then closing it at a certain angle, then fully opening it again, and finally fully closing it—avoids the situation where material 200 gets stuck between the valve and the first support frame 11 when the material distribution valve 30 is closed. This solves the problems of valve jamming and material jamming, ensuring the normal opening and closing of the material distribution valve 30, thereby guaranteeing the normal operation of the equipment and further improving the sorting efficiency and the purity of the sorted material 200.

[0098] The above description is merely a specific embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
