Description

Technical Field

[0001] The present invention relates to the technical field of recycling and utilization of renewable resources, and more particularly, to a material distribution device and a method for preventing material jamming of a valve. Background Art

[0002] For the classified recycling of garbage, a material distribution belt conveyor is usually used as the main material distribution device. Through a scientific and effective sorting and recycling system, the efficient circular utilization of resources can be realized, and waste can be converted into renewable resources. At present, the material distribution belt conveyor realizes the material diversion function through a gate-type material distribution valve. Specifically, the cylinder is vertically arranged to drive the valve to move up and down. When the valve descends and contacts the surface of the running belt, the material carried on the belt will be blocked by the valve and guided to the target bin along a certain angle formed between the valve and the belt.

[0003] However, in the actual operation process, some materials cannot be completely guided into the designated bin along the direction of the valve, but remain and accumulate on the surface of the belt or the valve. When the cylinder drives the valve to rise, these residual materials will continue to move with the belt and enter the next bin, thus causing the phenomenon of material mixing. This mixing situation not only reduces the purity of the sorted materials but also affects the overall sorting efficiency. Summary of the Invention

[0025] In a second aspect, the present invention provides a method for preventing material jamming in a valve, which is implemented by using the material distribution device according to any one of the foregoing embodiments. The method for preventing material jamming in the valve includes:

[0026] Controlling the material distribution conveyor to maintain an operating state;

[0027] Controlling the material distribution valve to rotate forward by a first preset angle or for a first preset duration, so that the material distribution valve is in the open state;

[0029] Controlling the material distribution valve to rotate forward by the second preset angle or for the second preset duration, so that the material distribution valve is in the open state;

[0030] Controlling the material distribution valve to rotate reversely by the first preset angle or for the first preset duration, so that the material distribution valve is in the closed state.

[0034] Controlling a purger to purge the material accumulated on the material distribution valve; and / or,

[0035] After the step of controlling the material distribution valve to rotate forward by the second preset angle or for the second preset duration so that the material distribution valve is in the open state, and before the step of controlling the material distribution valve to rotate backward by the first preset angle or for the first preset duration so that the material distribution valve is in the closed state, the valve anti-jamming method further includes:

[0036] Controlling a purger to purge the materials accumulated on the material distribution valve.

[0037] In an alternative embodiment, after the step of controlling the material distribution valve to rotate backward by the first preset angle or for the first preset duration so that the material distribution valve is in the closed state, the valve anti-jamming method further includes:

[0039] If the material distribution valve is not closed in place, controlling the material distribution valve to rotate forward by a third preset angle or for a third preset duration; 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;

[0042] The beneficial effects of the embodiments of the present invention include:

[0043] By rotatably arranging the material distribution valve on the material distribution conveyor, the material distribution device enables the material distribution valve to intercept the materials on the conveyor belt, and under the combined action of the guiding function of the material distribution valve and the conveying function of the material distribution conveyor, the materials are introduced into the silo. That is to say, when the material distribution valve is in the open state, the extending direction of the material distribution valve forms a certain angle with the conveying direction of the material distribution conveyor. During the conveying process, the materials will be intercepted by the material distribution valve. Since the material distribution conveyor continuously operates to convey the materials, the materials always move along the conveying direction of the material distribution conveyor. When the materials encounter the obstruction of the material distribution valve, they will gradually be introduced into the silo along the extending direction of the material distribution valve. It is easy to understand that since the material distribution valve rotates relative to the material distribution conveyor, during the closing process of the material distribution valve, it can further sweep the materials accumulated on the material distribution valve into the silo, thereby reducing the probability of material residue accumulating on the valve surface or the material distribution conveyor, and improving the purity of the sorted materials and the overall sorting efficiency.

[0044] The method for preventing material jamming of the valve is realized by using a material distributing device, which can improve the purity of the sorted material and the overall sorting efficiency. Moreover, by first fully opening the material distributing valve, closing it by a certain angle and then fully opening it again, and then fully closing the material distributing valve in this way of secondary jitter closing, the method can also avoid the situation where the material gets stuck between the valve and the first support frame when the material distributing valve is closed, solve the problems of valve jamming and material jamming, ensure the normal opening and closing of the material distributing valve, thus ensuring the normal operation of the equipment and further improving the sorting efficiency and the purity of the sorted material.

Detailed implementation

[0056] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0057] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0058] It should be noted that: like reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0059] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0060] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0061] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and defined, the terms "set", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] As described in the background art, the current material distribution belt conveyor realizes the material diversion function through a gate-type material diversion valve. However, in the actual operation process, some materials cannot be completely guided into the designated bin along the direction of the valve, but remain and accumulate on the surface of the belt or the valve. When the cylinder drives the valve to rise, these residual materials will continue to move with the belt and enter the next bin, thus causing the phenomenon of material mixing. This mixing situation not only reduces the purity of the sorted materials but also affects the overall sorting efficiency.

[0063] Based on this, please refer to Figures 1 - 9 , an embodiment of the present invention provides a material distribution device 100 and a method for preventing the valve from jamming with materials, which can effectively improve the above-mentioned technical problems, that is, it can improve the purity of the sorted materials 200 and the overall sorting efficiency. The following will describe the material distribution device 100 and the method for preventing the valve from jamming with materials in detail.

[0064] Please refer to Figures 1 - 3 , Figure 1 is a schematic structural view of the material distribution device 100 provided in this embodiment from the first perspective, Figure 2 is a schematic structural view of the material distribution device 100 provided in this embodiment from the second perspective, Figure 3 is a partial schematic structural view of the material distribution device 100 provided in this embodiment. Combining Figures 1 - 3 , the material distribution device 100 includes a material distribution and conveying mechanism 10, bins 20, and a material distribution valve 30.

[0065] Specifically, the bins 20 are arranged on one side of the material distribution and conveying mechanism 10 and are used to receive the materials 200 on the material distribution and conveying mechanism 10. The material distribution valve 30 is rotatably arranged on one side of the material distribution and conveying mechanism 10, and the material distribution valve 30 has an open state and a closed state. Among them, when the material distribution valve 30 is in the open state, the material distribution valve 30 is used to guide the materials 200 on the material distribution and conveying mechanism 10 into the bins 20; during the process of the material distribution valve 30 switching from the open state to the closed state, the material distribution valve 30 is used to sweep the materials 200 accumulated on the material distribution valve 30 and the material distribution and conveying mechanism 10 into the bins 20.

[0066] It should be noted that, Figure 2 andFigure 3 The X direction shown in the figure is the direction in which the material distribution and conveying mechanism 10 conveys the material 200. That is to say, when the material distribution valve 30 is in the open state, the extending direction of the material distribution valve 30 forms a certain angle with the X direction. During the conveying process, the material 200 will be intercepted by the material distribution valve 30. Since 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 storage bin 20 along the extending 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 of the material distribution valve 30, it can further sweep the material 200 accumulated on the material distribution valve 30 into the storage bin 20, thereby reducing the probability of the material 200 remaining and accumulating on the valve surface or the material distribution and conveying mechanism 10, and improving the purity of the sorted material 200 and the overall sorting efficiency.

[0067] During the process of the material distribution valve 30 guiding and sweeping the material 200, in order to better guide the material 200 and prevent the material 200 from falling outside the storage bin 20 during the sweeping process, in this embodiment, the material distribution device 100 further includes a guiding chute 70. The guiding chute 70 is arranged on one side of the material distribution and conveying mechanism 10. The material distribution valve 30 is located at the feeding port of the guiding chute 70 and is used to guide the material 200 on the material distribution and conveying mechanism 10 into the feeding port of the guiding chute 70. The discharging port of the guiding chute 70 is correspondingly arranged with the storage bin 20.

[0068] Furthermore, in order to facilitate the control of the rotation of the material distribution valve 30, achieve precise control of the opening and closing rotation angle of the material distribution valve 30, and further improve the sorting efficiency and the automation level of the equipment, in this embodiment, the material distribution device 100 further includes a driving member 40. The driving member 40 is arranged on one side of the material distribution and conveying mechanism 10, and the driving member 40 is connected to the material distribution valve 30. Of course, in some other embodiments, the driving member 40 may not be provided, and the material distribution valve 30 can be directly rotated manually to realize the diversion of the material 200 and the introduction of the residual material 200 into the storage bin 20.

[0069] It should be noted that in this embodiment, the driving member 40 is specifically a cylinder. Of course, in other embodiments, the driving member 40 can also be other driving structures such as a hydraulic cylinder or an electric push rod.

[0070] Please continue to refer to 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 arranged on opposite sides of the conveyor belt 13. The silo 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 arranged on the first support frame 11, and the driving member 40 is arranged 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.

[0071] It should be noted that in the prior art, the valve moves up and down, and its entire weight is directly borne by the cylinder, requiring a larger specification cylinder, resulting in an increase in equipment cost. Especially when the equipment is out of use for a long time, the cylinder is prone to air leakage, causing the valve to completely press on the belt under its own weight, making it difficult to start the belt conveyor and affecting the normal operation of the equipment. In this embodiment, in this rotational movement mode of the material distribution valve 30, when in the closed state, it can rotate and retract on the first support frame 11 without contacting the conveyor belt 13, which can ensure the normal operation of the conveyor belt 13 and other equipment. At the same time, the first support frame 11 mainly bears the weight of the material distribution valve 30, so that the driving force of the driving member 40 does not need to be too large, and there is no need to use a larger specification driving structure, thereby reducing the equipment cost.

[0072] In addition, it should also be noted that the open state mentioned above can be understood as the state when the material distribution valve 30 rotates to the maximum angle, that is, the state when the end of the material distribution valve 30 away from the driving member 40 abuts against the second support frame 12. At this time, it can ensure that all the materials 200 on the conveyor belt 13 can be intercepted and diverted by the material distribution valve 30. And the closed state mentioned above can be understood as the state when the material distribution valve 30 rotates and retracts to the first support frame 11, that is, the material distribution valve 30 will not cooperate with the conveyor belt 13 and is not located above the conveyor belt 13, which can ensure the normal flow of the materials 200 on the conveyor belt 13.

[0073] Further, please refer to Figure 4 , Figure 4 is Figure 3 the partial enlarged view of A in Figure 3 and Figure 4 , the material distribution valve 30 includes a rotating part 31 and a material distribution 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 material distribution and conveying mechanism 10. Specifically, in this embodiment, the other end of the rotating part 31 is rotatably connected to the first support frame 11; one end of the material distribution part 32 close to the driving member 40 is fixedly connected to the rotating part 31. Among them, when the material distribution valve 30 is in the open state, the end of the material distribution part 32 away from the rotating part 31 abuts against the second support frame 12.

[0074] As Figure 4 shown, by driving the rotating part 31 to rotate relative to the material distributing and conveying mechanism 10 through the driving part 40 to drive the material distributing part 32 to rotate, it can actually be understood as using the lever principle. That is, the driving part 40 applies power, the rotating part 31 is the power arm, and the connection point between the rotating part 31 and the first support frame 11 of the material distributing and conveying mechanism 10 is the fulcrum. The driving part 40 applies a force to the end of the rotating part 31 far from the first support frame 11, so as to facilitate driving the material distributing part 32 at one end of the first support frame 11 to rotate. It is easy to understand that since the resistance encountered by the material distributing part 32 is small during the opening process of the material distributing valve 30, the driving part 40 can apply a smaller driving force to drive the material distributing part 32 to rotate, so that the driving part 40 does not need to use a model with a large driving force, and the driving part 40 can select a driving structure with a smaller volume, thereby reducing the equipment cost and making the overall structure of the material distributing device 100 lighter.

[0075] For better installation and disassembly of the driving part 40, an installation part 111 is provided on one side of the material distributing and conveying mechanism 10. Specifically, in this embodiment, the installation part 111 is arranged on the side of the first support frame 11 away from the second support frame 12; the fixed end of the driving part 40 is hinged to the installation part 111, and the movable end of the driving part 40 is hinged to the rotating part 31.

[0076] As Figure 4 shown, by arranging the driving part 40 on the side of the first support frame 11 away from the second support frame 12, it is ensured that the driving part 40 will not interfere with other structures of the material distributing device 100 during the driving process, which can improve the installation stability of the driving part 40, and the process of driving the material distributing valve 30 is also smoother; at the same time, its disassembly and installation are convenient, which can improve the maintenance and installation efficiency.

[0077] Please refer to Figure 5 , Figure 5 , which is a partial structural schematic diagram of the first working condition of the material distributing device 100 provided in this embodiment. During the actual sorting of the material 200, there may be a situation where the material 200 accumulates at the contact position between the material distributing valve 30 and the second support frame 12, making it difficult for the material 200 here to be guided along the extension direction of the material distributing valve 30 to the middle area of the material distributing valve 30 under the action of the conveyor belt 13.

[0078] Therefore, in order to better guide the material 200 accumulated at the contact position between the material distributing valve 30 and the second support frame 12, please refer to Figure 6 , Figure 6 which Figure 3 is the partial enlarged view at B in Figure 3 and Figure 6, the material distribution device 100 further includes a first diversion plate 61. The first diversion plate 61 is disposed on the second support frame 12 and is used to cooperate with the material distribution valve 30. The first diversion plate 61 is inclined and also has a diversion function. It can cooperate with the material distribution valve 30 when the material distribution valve 30 is in the open state to divert the material 200, thereby improving the sorting efficiency.

[0079] Further, to improve the diversion effect, when the material distribution valve 30 is in the open state, the first diversion plate 61 is parallel to the material distribution valve 30.

[0080] Please refer to Figure 7 , Figure 7 which is a partial structural schematic diagram of the first working condition of the material distribution device 100 provided in this embodiment. In combination with Figures 5 - 7 , it should be noted that during the actual sorting process, there may also be a situation where there is a large amount of material 200. And there is a large accumulation of material 200 at the contact between the material distribution valve 30 and the second support frame 12 or between the material distribution valve 30 and the first diversion plate 61. As a result, when the material distribution valve 30 is being closed, some residual material 200 is likely to get stuck between the protective plate of the material distribution valve 30 and the second support frame 12, or is likely to get stuck between the material distribution valve 30 and the guide chute 70, making the material distribution valve 30 unable to close normally and affecting the sorting efficiency and the normal operation of the equipment.

[0081] Therefore, in order to further reduce the probability of residual material 200 accumulating on the valve surface or the material distribution and conveying mechanism 10, and to reduce the probability of the valve getting stuck and the material getting stuck, in this embodiment, the material distribution device 100 further includes a purger 50. The purger 50 is disposed on the second support frame 12 and is used to purge the material 200 accumulated on the material distribution valve 30 when the material distribution valve 30 is in the open state.

[0082] To improve the purging effect and further enhance the sorting efficiency and the purity of the sorted material 200, when the material distribution valve 30 is in the open state, the purger 50 is arranged parallel to the material distribution valve 30. That is to say, the purging direction of the purger 50 is the extending direction of the material distribution valve 30, which can better blow the material 200 along the extending direction of the material distribution valve 30 to the middle area of the material distribution valve 30 or the area near the silo 20, so as to ensure that when the material distribution valve 30 is being closed, the material 200 can be better swept into the silo 20.

[0083] In combination with Figure 6 , in this embodiment, the purger 50 is disposed on the side of the first diversion plate 61 away from the material distribution valve 30, thereby further improving the purging effect and enhancing the sorting efficiency.

[0084] Please continue to combine Figure 4, To avoid interference between one end of the material distribution valve 30 close to the driving member 40 and the material guiding groove 70 or the storage bin 20 during the closing process of the material distribution valve 30, and to prevent the material 200 from getting stuck between the material distribution valve 30 and the material guiding groove 70 or the storage bin 20, in this embodiment, the material distribution device 100 further includes a second guiding plate 62, and the second guiding plate 62 is arranged at one end of the material distribution valve 30 close to the first support frame 11. The second guiding plate 62 also has a guiding function, which can facilitate the introduction of the material 200 into the material guiding groove 70 or the storage bin 20, thus ensuring the normal closing of the material distribution valve 30 and further improving the sorting efficiency.

[0085] Furthermore, to detect whether the material distribution valve 30 is closed in place, in this embodiment, the material distribution device 100 further includes a proximity switch, and the proximity switch is arranged on the driving member 40. Of course, in some of its implementation manners, it is also possible to detect whether the valve is closed in place through a detection switch. For example, in other embodiments, the material distribution device 100 further includes a detection switch, and the detection switch is arranged on one side of the material distribution and conveying mechanism 10. Specifically, the detection switch is arranged on the first support frame 11.

[0086] Please continue to refer to Figures 1 - 3 , the number of the storage bins 20 and the material distribution valves 30 are both multiple. The multiple storage bins 20 are arranged in sequence along the extending direction of the material distribution and conveying mechanism 10, and the multiple material distribution valves 30 are arranged in one-to-one correspondence with the multiple storage bins 20, which can further improve the sorting efficiency and save the equipment installation space. Of course, in this embodiment, correspondingly, the number of the driving members 40, the purging devices 50, the first guiding plates 61, the second guiding plates 62, and the material guiding grooves 70 are all multiple.

[0087] In addition, referring to Figure 1 , to facilitate the installation of the material distribution and conveying mechanism 10, in this embodiment, the material distribution device 100 further includes a conveying platform 80, and the material distribution and conveying mechanism 10 is arranged on the conveying platform 80.

[0088] Please refer to Figure 8 and Figure 9 , Figure 8 is a partial structural schematic diagram of the third working condition of the material distribution device 100 provided in this embodiment. Figure 9 is a flow block diagram of the valve anti-blocking method provided in this embodiment. Referring to Figure 8 and Figure 9 , the valve anti-blocking method includes:

[0089] Step S10: Control the material distribution and conveying mechanism 10 to maintain the operating state;

[0090] Step S20: Control the material distribution valve 30 to rotate forward by a first preset angle or a first preset duration, so that the material distribution valve 30 is in an open state;

[0091] Step S40: Control the material distribution valve 30 to reverse by a second preset angle or for a 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;

[0092] Step S60: Control the material distribution valve 30 to rotate forward by the second preset angle or for the second preset duration, so that the material distribution valve 30 is in an open state;

[0093] Step S70: Control the material distribution valve 30 to reverse by the first preset angle or for the first preset duration, so that the material distribution valve 30 is in a closed state.

[0094] It should be noted that the first preset angle can be understood as the maximum angle to which the material distribution valve 30 rotates, such as Figure 3 the first preset angle θ1 shown; as Figure 8 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 duration used by the material distribution valve 30 from being closed to being fully opened, and the second preset duration can be understood as the duration used by the material distribution valve 30 from being fully opened to closing by a certain angle. For example, the first preset duration is T1, and the second preset duration is T2, that is, T2 < T1.

[0095] That is to say, during the sorting process of the material 200, after the material distribution valve 30 is fully opened for the first time to intercept and guide the material 200, it will not be directly closed, but will first close by a certain angle, and then be fully opened for the second time. This can enable the material ② at the end of the material distribution valve 30 far from the driving member 40, or the material 200 accumulated between the material distribution valve 30 and the first guide plate 61 in the open state, to first move a certain distance along with the material distribution valve 30 towards the silo 20. Then, when the material distribution valve 30 is fully opened again, this part of the material 200 will be briefly separated from the material distribution valve 30, and under the conveying action of the conveyor belt 13, continue to move a certain distance along the X direction, and then contact the material distribution valve 30 again. At this time, this part of the material 200 will not accumulate between the material distribution valve 30 and the first guide plate 61, but will be located at a position of the material distribution valve 30 close to the silo 20, which can be in the middle area or the middle and lower area of the material distribution valve 30, etc. Then, the material distribution valve 30 is reversed and closed again to sweep this part of the material 200 into the silo 20.

[0096] It should be noted that the above valve anti-jamming method can be understood as a secondary jitter closing method, which can avoid the situation where the material 200 gets stuck between the valve and the first support frame 11 when the material distribution valve 30 is closed, solves the problems of valve jamming and material jamming, ensures the normal opening and closing of the material distribution valve 30, thus ensuring the normal operation of the equipment, and further improving the sorting efficiency and the purity of the sorted material 200.

[0097] Optionally, when the material distribution valve 30 is closed to the half-open state, that is, when the material distribution valve 30 is in the half-closed state, its jitter effect is better, which can improve the subsequent material sweeping effect and sorting efficiency. That is, in this embodiment, θ1 = 2θ2. Of course, in other embodiments, the size relationship between θ1 and θ2 can also be other values.

[0098] During the actual process of operating the valve to open and close, it is not easy to control the rotation angle of the material distribution valve 30. To more conveniently achieve the state of closing the material distribution valve 30 to the half-open state, it can be achieved by controlling the forward or reverse rotation duration of the material distribution valve 30, that is, T1 = 2T2. For example, in this embodiment, the material distribution device 100 further includes a speed regulator, and the speed regulator is arranged on the driving member 40.

[0099] For controlling the material distribution valve 30 to reverse by a second preset angle so that the material distribution valve 30 is in the half-open or half-closed position, it can be controlled by using the speed regulator based on the rotation time. Specifically, the speed regulator can be controlled to appropriately slow down the action speed of the driving member 40, and the time from the start to the end of the driving member 40 can be tested. This time can be understood as the first preset duration T1. Based on half of this time, the half-open duration of the driving member 40 is set, that is, this half-open duration can be understood as the second preset duration T2, and the relationship between the two is T1 = 2T2, so as to achieve the effect of relatively accurately controlling the driving member 40 to drive the material distribution valve 30 to be in the half-open position.

[0100] Please continue to combine Figure 9 To further improve the sorting efficiency and reduce the probability of material jamming or valve jamming, after step S20 and before step S40, the valve anti-jamming method further includes:

[0101] Step S30: Control the blower 50 to blow the material 200 accumulated on the material distribution valve 30.

[0102] That is to say, when the material distribution valve 30 is fully opened for the first time, by blowing the material 200 with the blower 50 first, most of the material 200 can be in the middle or lower-middle region of the material distribution valve 30, thereby further reducing the probability of material jamming during the closing process of the material distribution valve 30.

[0103] Similarly, after step S40 and before step S60, the valve anti-jamming method further includes:

[0104] Step S50: Control the blower 50 to blow the material 200 accumulated on the material distribution valve 30.

[0105] That is to say, when the material distribution valve 30 is fully opened for the second time, the material 200 can be purged by the purger 50 first, which can further make part of the residual material 200 be in the middle or the 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.

[0106] Please continue to combine Figure 9 , when the material distribution valve 30 is closing, there may still be a situation of material jamming. Therefore, in this embodiment, after step S70, the valve anti-jamming method further includes:

[0107] Step S80: Detect whether the material distribution valve 30 is closed in place;

[0108] Step S91: If the material distribution valve 30 is closed in place, control the material distribution conveyor 10 to stop running.

[0109] 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 for 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.

[0110] Step S93: Control the material distribution valve 30 to rotate backward by a third preset angle or for a third preset duration, so that the material distribution valve 30 is in a closed state.

[0111] That is to say, if it is detected that the material distribution valve 30 is closed in place, there is no situation of material jamming, and the shutdown operation can be performed. Of course, if it is detected that the material distribution valve 30 is not closed in place, it means that there is a situation of material jamming, and the material distribution valve 30 needs to be further opened to make the material distribution valve 30 shake for the 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 storage bin 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.

[0112] It should be noted that, in this embodiment, the material distribution device 100 further includes a controller, and the controller is simultaneously in communication with the driving member 40, the material distribution conveyor 10, the purger 50, the speed regulator, the detection switch, and the proximity switch, so as to ensure the orderly control of each structure of the entire material distribution device 100 and realize the function of valve anti-jamming.

[0113] In summary, the embodiments of the present invention provide a material distribution device 100 and a method for preventing material jamming in a valve. The material distribution device 100 includes a material distribution conveying mechanism 10, a material bin 20, and a material distribution valve 30. The material bin 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 the material distribution valve 30 has an open state and a closed state. Wherein, when the material distribution valve 30 is in the open state, the material distribution valve 30 is used to introduce the material 200 on the material distribution conveying mechanism 10 into the material bin 20. During the process of the material distribution valve 30 switching from the open state to the closed state, the material distribution valve 30 is used to sweep the material 200 accumulated on the material distribution valve 30 and the material distribution conveying mechanism 10 into the material bin 20.

[0114] By rotatably disposing the material distribution valve 30 on the material distribution conveying mechanism 10, the material distribution device 100 enables the material distribution valve 30 to intercept the material 200 on the conveyor belt 13, and under the combined action of the guiding function of the material distribution valve 30 and the conveying function of the material distribution conveying mechanism 10, the material 200 is introduced into the material bin 20. That is to say, when the material distribution valve 30 is in the open state, the extending direction of the material distribution valve 30 forms a certain angle with the conveying direction of the material distribution conveying mechanism 10. During the conveying process, the material 200 will be intercepted by the material distribution valve 30. Since the material distribution conveying mechanism 10 continuously operates to convey 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 introduced into the material bin 20 along the extending 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 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 material bin 20, thereby reducing the probability of the material 200 remaining and accumulating 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.

[0115] The method for preventing material jamming in the valve is realized by using the material distribution device 100, which can improve the purity of the sorted material 200 and the overall sorting efficiency. Moreover, by the way of closing the material distribution valve 30 with two - time jitter, that is, first fully opening the material distribution valve 30, then closing it by a certain angle and then fully opening it again, and finally fully closing the material distribution valve 30, it can also avoid the situation where the material 200 gets stuck between the valve and the first support frame 11 when the material distribution valve 30 is closed, solve the problems of valve jamming and material jamming, ensure the normal opening and closing of the material distribution valve 30, thus ensuring the normal operation of the equipment, and further improving the sorting efficiency and the purity of the sorted material 200.
