Description

Technical Field

[0001] This application relates to the field of material conveying technology, and in particular to a feeding mechanism and material processing equipment. Background Technology

[0002] When materials are fed from the material bag into the material silo or other devices, there is a gap between the material bag's outlet and the silo's inlet because the inlet lacks a sealing device. As the material falls into the silo, it experiences a strong backlash, causing it to overflow when feeding stops, resulting in high dust concentrations in the surrounding environment and potentially affecting the operator's health. Summary of the Invention

[0003] This application provides a feeding mechanism and material processing equipment, which can improve the efficiency of material transportation and prevent the material in the receiving bin from backflowing upwards and spilling into the surrounding operating environment.

[0004] This application provides a feeding mechanism, including a feeding bin, a conveying pipe assembly, a receiving bin, and at least one baffle assembly. One end of the conveying pipe assembly is connected to the feeding bin, and the other end of the conveying pipe assembly is connected to the receiving bin.

[0005] The baffle assembly is hinged to one end of the conveying pipe assembly near the receiving hopper. The baffle assembly includes a hinge axis N and a first structural segment and a second structural segment disposed on both sides of the hinge axis N.

[0006] When the first structural segment and the second structural segment in each of the baffle assemblies are in force balance, the end of the conveying pipe assembly near the receiving bin is closed by the cooperation of all the first structural segments.

[0007] Based on the above technical solution, when the conveying pipe assembly stops feeding material to the receiving hopper, the first structural section of each baffle assembly can seal the end of the conveying pipe assembly near the receiving hopper. This prevents the upward-flowing material in the receiving hopper from re-entering the conveying pipe assembly, thus avoiding the overflow of backflowing material from the assembly gaps of the conveying pipe assembly and increasing the dust concentration in the surrounding operating environment. This ensures the health of operators, reduces material loss, speeds up the feeding process, and improves conveying efficiency.

[0008] In some possible implementations, the baffle assembly includes a baffle plate and an eccentric block;

[0009] The baffle plate is hinged to one end of the conveying pipe assembly near the receiving hopper, and the eccentric block is connected to one end of the baffle plate near the second structural section.

[0010] In some possible implementations, the baffle assembly further includes a connecting rod, through which the eccentric block is connected to the baffle plate;

[0011] Parallel to the direction from the second structural segment to the first structural segment, the connecting rod includes a plurality of mounting positions arranged sequentially, and the eccentric block is detachably mounted at any of the mounting positions.

[0012] In some possible implementations, the feeding mechanism further includes at least one limiting member, which is fixedly connected to one end of the conveying pipe assembly near the receiving bin;

[0013] When all the first structural segments close one end of the feed pipe assembly near the receiving hopper, all the first structural segments abut against the side of the at least one limiting member away from the feed hopper.

[0014] In some possible implementations, the feed tube assembly includes a negative pressure chamber;

[0015] The negative pressure chamber includes a negative pressure cavity and a negative pressure source interface, and the negative pressure source interface is connected to the negative pressure cavity.

[0016] In some possible implementations, the feed tube assembly further includes a filter element installed at the negative pressure source interface location, the negative pressure source interface being connected to the negative pressure chamber through the filter element.

[0017] In some possible implementations, the feeding mechanism further includes a first detection element, which is installed at one end of the feeding bin near the conveying pipe assembly;

[0018] When the feeding hopper is filled with material, the first detection element outputs a first detection signal;

[0019] When the feed hopper is empty, the first detection element outputs a second detection signal.

[0020] In some possible implementations, when the first structural segment and the second structural segment in each of the baffle assemblies are unbalanced in force, the end of the conveying pipe assembly near the receiving bin opens;

[0021] The feeding mechanism further includes a second detection element, which is located at one end of the feeding pipe assembly near the baffle assembly;

[0022] When the end of the feed pipe assembly near the receiving hopper is closed by all the first structural sections, the second detection element outputs a third detection signal;

[0023] When the end of the feed pipe assembly near the receiving hopper is opened, the second detection element outputs a fourth detection signal.

[0024] In some possible implementations, when the first detection element outputs the first detection signal and the second detection element outputs the third detection signal, the negative pressure chamber is in a negative pressure state;

[0025] When the first detection element outputs the first detection signal and the second detection element outputs the fourth detection signal, the negative pressure chamber is in a normal pressure state.

[0026] In addition, this application also provides a material processing device, including the feeding mechanism described in the above embodiments. Attached Figure Description

[0042] The embodiment provides a feeding mechanism that can be used in processing equipment for materials such as positive / negative electrode materials, magnetic materials, or lithium cobalt oxide.

[0043] like Figure 1 As shown, the feeding mechanism may include a feeding bin 10, a conveying pipe assembly 20, a receiving bin 30, and at least one baffle assembly 40. The feeding bin 10 is used to supply materials. The feeding bin 10 may include a first storage chamber 11 and a discharge port 12. During the use of the feeding mechanism, the first storage chamber 11 can be used to store a certain amount of material. In this embodiment, the discharge port 12 may be connected to the first storage chamber 11. The material in the first storage chamber 11 can be discharged through the discharge port 12. In some embodiments, the feeding bin 10 may be a feeding hopper.

[0044] In other embodiments, the feeding bin 10 may also be a material bag or a discharge bin of an upstream processing equipment.

[0045] The receiving hopper 30 can be used to receive materials provided by the supply hopper 10. In this embodiment, the receiving hopper 30 may include a second storage chamber 31 and a feed inlet 32. The feed inlet 32 ​​may be connected to the second storage chamber 31. The materials provided by the supply hopper 10 can enter the second storage chamber 31 through the feed inlet 32. In some embodiments, the receiving hopper 30 may be a material hopper or a hopper of a processing equipment, etc.

[0046] like Figure 1As shown, the conveying pipe assembly 20 can generally be in the form of a tubular structure. The conveying pipe assembly 20 may include two connected open ends, namely a first open end 202 and a second open end 203. In this embodiment, the first open end 202 of the conveying pipe assembly 20 can be connected to the outlet 12 of the feeding hopper 10. The second open end 203 of the conveying pipe assembly 20 can be connected to the inlet 32 ​​of the receiving hopper 30. Thus, the material output from the feeding hopper 10 can be conveyed to the receiving hopper 30 through the conveying pipe assembly 20.

[0047] Combined again Figure 4 In some embodiments, the end of the conveying pipe assembly 20 near the feeding bin 10 can extend into the second storage chamber 31 of the receiving bin 30 through the inlet 32. That is, the end of the conveying pipe assembly 20 near the feeding bin 10 protrudes relative to the end of the inlet 32 ​​near the second storage chamber 31, and the second opening end 203 can be located in the second storage chamber 31.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the feeding mechanism may include two sets of baffle assemblies 40, which are symmetrically installed on the second open end 203 of the conveying pipe assembly 20, and the structures of the two sets of baffle assemblies 40 may be symmetrical. The following is a detailed description using one of the baffle assemblies 40 as an example.

[0049] Combined again Figure 4 and Figure 5 The baffle assembly 40 is hinged to the second open end 203 of the feed tube assembly 20. Accordingly, the baffle assembly 40 may include a hinge axis N. In this embodiment, the baffle assembly 40 may include a first structural segment 401 and a second structural segment 402, which may be disposed on opposite sides of the hinge axis N. When the feeding mechanism is not in use, the first structural segment 401 may be opposite to the second open end 203 of the feed tube assembly 20.

[0050] During the operation of the feeding mechanism, the first structural segment 401 is subjected to gravity and the pressure of the material, which can be combined and denoted as the first force F1. The lever arm between the first structural segment 401 and the hinge axis N can be denoted as the first lever arm L1. Similarly, the second structural segment 402 is subjected to gravity, which can be denoted as the second force F2. The lever arm between the second structural segment 402 and the hinge axis N can be denoted as the second lever arm L2.

[0051] In this embodiment, the first structural segment 401 may have a first torque M1 relative to the hinge axis N, where M1 = L1 * L1. Similarly, the second structural segment 402 may have a second torque M2 relative to the hinge axis N, where M2 = F2 * L2.

[0052] When the first torque M1 of the first structural segment 401 in the baffle assembly 40 is less than or equal to the second torque M2 of the second structural segment 402, the first structural segment 401 can close part of the second open end 203 of the conveying pipe assembly 20. It is understood that the first structural segments 401 in both sets of baffle assemblies 40 can cooperate to completely close the second open end 203, even if the conveying pipe assembly 20 is disconnected from the second storage chamber 31. In this state, the end faces of the two first structural segments 401 that are close to each other can fit together. Of course, a certain assembly gap is allowed between the end faces of the two first structural segments 401 that are close to each other. Correspondingly, the second open end 203 of the conveying pipe assembly 20 may include a closed state 2031.

[0053] When the first torque M1 of the first structural segment 401 is greater than the second torque M2 of the second structural segment 402, the baffle assembly 40 can be driven to rotate around the hinge axis N, thereby causing the first structural segment 401 to gradually move away from the second open end 203 of the conveying pipe assembly 20. Correspondingly, the second open end 203 of the conveying pipe assembly 20 can gradually open and communicate with the second storage chamber 31. It can be understood that when the first torque M1 of the first structural segment 401 is greater than the second torque M2 of the second structural segment 402, the first structural segments 401 in the two baffle assemblies 40 move away from each other, forming an opening. Material in the conveying pipe assembly 20 can enter the second storage chamber 31 through the opening between the two baffle assemblies 40. Correspondingly, the second open end 203 of the conveying pipe assembly 20 may also include an open state 2032.

[0054] It should be noted that, in addition to gravity and the pressure exerted by the material, the first structural segment 401 and the second structural segment 402 may also be subjected to forces exerted by other structural components. In the embodiment, when the second opening end 203 is in the closed state 2031, the first structural segment 401 and the second structural segment 402 are in force balance. When the second opening end 203 is in the open state 2032, the first structural segment 401 and the second structural segment 402 are out of force balance.

[0055] In other embodiments, the feeding mechanism may also include one, three, or five sets of baffle assemblies 40. When the feeding mechanism includes multiple sets of baffle assemblies 40, the multiple sets of baffle assemblies 40 may be arranged sequentially around the central axis of the second opening end 203. When the second opening end 203 of the conveying pipe assembly 20 is in a closed state 2031, it can be closed by the first structural section 401 of the multiple sets of baffle assemblies 40.

[0056] Taking a set of baffle assemblies 40 as an example, during the use of the feeding mechanism, as the material on the first structural section 401 gradually increases, the first force F1 acting on the first structural section 401 will gradually increase. Simultaneously, the first torque M1 of the first structural section 401 relative to the hinge axis N will also gradually increase. When the first torque M1 of the first structural section 401 is greater than the second torque M2 of the second structural section 402, the baffle assembly 40 can rotate forward relative to the conveying pipe assembly 20 to open the second opening end 203 of the conveying pipe assembly 20, placing the second opening end 203 in an open state 2032. The second opening end 203 can communicate with the second storage chamber 31 of the receiving bin 30. Simultaneously, the material on the first structural section 401 can slide off the first structural section 401 under gravity and fall into the second storage chamber 31. It is understandable that when material is continuously conveyed in the conveying pipe assembly 20, the first structural section 401 can be subjected to the continuous force of the material, and the first torque M1 is kept greater than the second torque M2, so that the second opening end 203 of the conveying pipe assembly 20 is kept in the open state 2032, allowing the material to continuously enter the receiving bin 30.

[0057] When material stops falling into the conveying pipe assembly 20, the first structural section 401 is no longer subjected to the force of the material. In this state, the force exerted by the material on the first structural section 401 is zero, and the first torque M1 of the first structural section 401 is less than the second torque M2 of the second structural section 402. This can drive the baffle assembly 40 to rotate in the opposite direction, thereby closing the second open end 203 of the conveying pipe assembly 20, i.e., the second open end 203 of the conveying pipe assembly 20 is in a closed state 2031. This prevents material falling into the second storage chamber 31 from backflowing into the conveying pipe assembly 20 and overflowing outwards. Furthermore, it reduces dust spillage into the surrounding operating environment, improves the operating environment, and ensures the health of operators. Simultaneously, it also reduces material loss, accelerates the feeding speed, and improves conveying efficiency.

[0058] like Figure 1 As shown, the feeding mechanism further includes a feeding valve 50. The feeding valve 50 can be installed at the discharge port 12 of the feeding hopper 10. The feeding valve 50 can be used to control the opening and closing of the discharge port 12, that is, to control whether the feeding hopper 10 supplies material to the conveying pipe assembly 20. It can be understood that the input port of the feeding valve 50 can be connected to the first storage chamber 11, and the output end of the feeding valve 50 can be connected to the first opening end 202 of the conveying pipe assembly 20.

[0059] In other embodiments, it is not excluded that the feed valve 50 is installed at the first open end 202 of the feed pipe assembly 20.

[0060] like Figure 1As shown, the feeding mechanism may also include a first detection element 61, which can be used to detect whether there is material in the feeding bin 10. Specifically, the first detection element 61 may be installed at one end of the feeding bin 10 near the discharge port 12, and the first detection element 61 may be located on the inner wall of the feeding bin 10 near the first storage chamber 11.

[0061] In some embodiments, the first detection element 61 may be a pressure sensor. When there is material in the feeding hopper 10, a certain pressure is applied to the first detection element 61, and the first detection element 61 can output a first detection signal. When there is no material in the feeding hopper 10, the first detection element 61 fails to sense the pressure, and the first detection element 61 can output a second detection signal.

[0062] In some embodiments, the feeding mechanism may further include an electrically connected alarm structure (not shown) and a controller (not shown). A first detection element 61 may be electrically connected to the controller and may send a detection signal to the controller. When the controller receives a second detection signal from the first detection element 61, it indicates that there is no material in the feeding hopper 10, and the controller may control the alarm structure to issue an alarm signal to remind the operator to add material to the feeding hopper 10. In some embodiments, the alarm structure may include a speaker and / or indicator lights, etc.

[0063] In other embodiments, the first detection element 61 may also be a structural component such as an infrared sensor or an ultrasonic sensor.

[0064] In other embodiments, the electrical components in the feeding mechanism can also be directly connected to the main controller of the material processing equipment. Accordingly, the feeding mechanism may not require an additional controller.

[0065] like Figure 1 and Figure 6 As shown, it can be understood that the interior of the conveying tube assembly 20 is a hollow structure and can form a conveying cavity 201. The conveying cavity 201 can penetrate the conveying tube assembly 20, that is, the conveying cavity 201 can extend from the first opening end 202 to the second opening end 203, and the conveying cavity 201 is connected to the first opening end 202 and the second opening end 203 respectively.

[0066] In some embodiments, the feed tube assembly 20 may include a negative pressure chamber 21, a flexible tube 22, and a feed tube 23. The flexible tube 22 may connect the negative pressure chamber 21 and the feed tube 23. The feed chamber 201 may sequentially pass through the negative pressure chamber 21, the flexible tube 22, and the feed tube 23. The end of the negative pressure chamber 21 away from the flexible tube 22 may serve as the first open end 202 of the feed tube assembly 20, and the end of the feed tube 23 away from the flexible tube 22 may serve as the second open end 203 of the feed tube assembly 20.

[0067] like Figure 6As shown, the negative pressure chamber 21 may include a negative pressure cavity 211 and a negative pressure source interface 212. The negative pressure source interface 212 may communicate with the negative pressure cavity 211. In some embodiments, the negative pressure source interface 212 may be used to connect a negative pressure supply structure such as a vacuum pump or a Roots blower, and correspondingly, the negative pressure supply structure can evacuate the negative pressure cavity 211 through the negative pressure source interface 212. In some embodiments, the negative pressure source interface 212 may be located on the circumferential sidewall of the negative pressure chamber 21.

[0068] Additionally, the feed pipe assembly 20 may also include a filter element 24, which can be installed inside the negative pressure chamber 21 and located at the negative pressure source interface 212. The filter element 24 can filter the airflow passing through the negative pressure source interface 212 to prevent material from entering the negative pressure source interface 212 from the negative pressure chamber 211 and being discharged. On the one hand, this reduces material loss. On the other hand, it also prevents material from entering the negative pressure supply structure and damaging it.

[0069] In some embodiments, the flexible tube 22 may be a soft connection, and the flexible tube 22 is sealed to the negative pressure chamber 21 and the feed pipe 23 respectively, so as to realize the sealed connection between the negative pressure chamber 21 and the feed pipe 23.

[0070] In other embodiments, the flexible tube 22 may be selected from structures such as corrugated tubes.

[0071] like Figure 1 and Figure 6 As shown, the two baffle assemblies 40 can be installed at the end of the feed pipe 23 away from the flexible pipe 22. The following is a detailed description using one of the baffle assemblies 40 as an example.

[0072] Combined again Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, the baffle assembly 40 may include a baffle plate 41, an eccentric block 42, and a connecting rod 43.

[0073] The baffle plate 41 is hinged to the second open end 203 of the feed pipe assembly 20, meaning the baffle plate 41 can rotate relative to the feed pipe assembly 20. In some embodiments, opposing rotating shafts 413 can be fixedly mounted on the baffle plate 41. A pair of connecting arms 231 can be provided on the outer wall of the feed pipe assembly 20, and the two rotating shafts 413 can be rotatably connected to the two connecting arms 231 one-to-one via a dustproof bearing 80. It can be understood that the rotating shafts 413 can be coaxial with the hinge axis N.

[0074] In this embodiment, the baffle plate 41 may include a first panel portion 411 and a second panel portion 412. The first panel portion 411 and the second panel portion 412 may be disposed on opposite sides of the hinge axis N. The first panel portion 411 is located near the first structural segment 401, and the second panel portion 412 is located near the second structural segment 402.

[0075] The eccentric block 42 can be connected to the end of the baffle plate 41 near the second structural section 402 via the connecting rod 43. Specifically, the eccentric block 42 is connected to the end of the second panel portion 412 away from the first panel portion 411 via the connecting rod 43. Correspondingly, the gravity of the first structural section 401 may include the gravity of the first panel portion 411. The gravity of the second structural section 402 may be the sum of the gravity of the second panel portion 412, the connecting rod 43, and the eccentric block 42.

[0076] When the first torque M1 of the first structural segment 401 is less than or equal to the second torque M2 of the second structural segment 402, the first panel portion 411 can partially close the second opening end 203. It is understood that the first panel portions 411 of the two baffle plates 41 can cooperate to completely close the second opening end 203. In this embodiment, the shape of the baffle plate 41 can be set to a semi-circular, rectangular, symmetrical, or pentagonal shape, etc., without specific limitations, as long as it ensures that the two first panel portions 411 cooperate to completely close the second opening end 203 of the conveying pipe assembly 20.

[0077] When the first torque M1 of the first structural section 401 is greater than the second torque M2 of the second structural section 402, the first panel 411 rotates in the forward direction away from the material conveying pipe assembly 20, which can open the second opening end 203 of the material conveying pipe assembly 20.

[0078] like Figure 2 and Figure 3 As shown, further, the axial direction of the connecting rod 43 can be perpendicular to the hinge axis N and the axial direction of the conveying pipe assembly 20. From the second structural segment 402 to the first structural segment 401 (i.e., perpendicular to the hinge axis N), the connecting rod 43 may include a plurality of sequentially arranged mounting positions 4301. The eccentric block 42 can be detachably mounted at any mounting position 4301. When the eccentric block 42 is mounted at different mounting positions 4301, the center of gravity of the second structural segment 402 can be shifted, thereby adjusting the magnitude of the second torque M2. Thus, the first structural segment 401 can be rotated forward under the triggering of materials of different weights to open the second opening end 203 of the conveying pipe assembly 20.

[0079] Understandably, when the eccentric block 42 is adjusted away from the second panel portion 412, the second torque M2 increases accordingly. Consequently, the first structural section 401 can withstand a relatively large weight of material, meaning a larger weight of material is needed to trigger the baffle plate 41 to rotate forward and open the second opening end 203 of the conveying pipe assembly 20. When the eccentric block 42 is adjusted closer to the second panel portion 412, the second torque M2 decreases accordingly. Consequently, the first structural section 401 can withstand a relatively small weight of material, meaning a smaller weight of material can trigger the baffle plate 41 to rotate forward and open the second opening end 203 of the conveying pipe assembly 20.

[0080] In some embodiments, the connecting rod 43 may be a screw, and the eccentric block 42 may be a nut, with the nut being compatible with the screw. The eccentric block 42 may be installed on the connecting rod 43 via a threaded connection. When it is necessary to adjust the eccentric block 42 to different mounting positions 4301, the eccentric block 42 may be rotated relative to the connecting rod 43 to switch between different mounting positions 4301.

[0081] like Figure 3 As shown, in some embodiments, multiple first positioning holes 431 may be provided on the connecting rod 43 along its axial direction, and the axial direction of the first positioning holes 431 may be perpendicular to the axial direction of the connecting rod 43. The multiple first positioning holes 431 may correspond one-to-one with multiple mounting positions 4301. An eccentric block 42 may be sleeved on the connecting rod 43, and a second positioning hole 421 may be provided on the eccentric block 42, the axial direction of the second positioning hole 421 may also be perpendicular to the axial direction of the connecting rod 43. When it is necessary to position the eccentric block 42 at a specific mounting position 4301, the second positioning hole 421 may be aligned with and connected to the first positioning hole 431 of the specific mounting position 4301. Subsequently, a pin may be inserted sequentially through the second positioning hole 421 and the first positioning hole 431 to position the eccentric block 42 at that mounting position 4301.

[0082] Of course, in other embodiments, the eccentric block 42 may also be directly fixed to the end of the second panel portion 412 away from the first panel portion 411.

[0083] In other embodiments, the length of the second panel portion 412 along the axial direction of the connecting rod 43 can be set to zero. That is, the baffle plate 41 may only include the first panel portion 411. Accordingly, the gravity of the second structural segment 402 may be the sum of the gravity of the connecting rod 43 and the eccentric block 42.

[0084] In other embodiments, the length of the second panel portion 412 may be greater than or equal to the length of the first panel portion 411 in a direction perpendicular to both the baffle plate 41 and the hinge axis N, and the baffle assembly 40 may be exempt from the need for the eccentric block 42 and the connecting rod 43. Accordingly, the weight of the second structural segment 402 may be the weight of the second panel portion 412.

[0085] like Figure 2 and Figure 4 As shown, the feeding mechanism further includes at least one limiting member 70. In some embodiments, the feeding mechanism may include a limiting member 70, which may be rod-shaped and may extend radially through the second opening end 203. Both ends of the limiting member 70 may be fixedly connected to the inner wall of the feed pipe 23. In some embodiments, the limiting member 70 may be perpendicular to the axial direction of the connecting rod 43.

[0086] Of course, in other embodiments, the limiting member 70 may also be extended along any other diameter of the second opening end 203.

[0087] When the second opening end 203 is in the closed state 2031, that is, when the first panel portion 411 of the two baffle plates 41 closes the second opening end 203, the ends of the two first panel portions 411 that are close to each other can abut against the side of the limiting member 70 away from the feeding bin 10. The limiting member 70 can prevent the baffle plates 41 from rotating excessively when they rotate in the opposite direction, and prevent the two baffle plates 41 from rotating excessively and forming a leakage gap. It can be understood that when both baffle plates 41 abut against the limiting member 70, the two baffle plates 41 can completely close the second opening end 203, and both baffle plates 41 can be perpendicular to the direction of gravity.

[0088] In other embodiments, the feeding mechanism may also include two, three, or five limiting members 70, and the multiple limiting members 70 may be configured one-to-one with multiple baffles 41. The limiting members 70 may be configured as rod-shaped or block-shaped structures as needed.

[0089] In other embodiments, the baffle plate 41 may protrude circumferentially relative to the radial direction of the feed tube assembly 20. Thus, the feed tube assembly 20 can provide a limiting effect for the baffle plate 41, eliminating the need for a limiting element 70 in the unloading mechanism.

[0090] like Figure 4 and Figure 5 As shown, the feeding mechanism further includes at least one second detection element 62. In some embodiments, the feeding mechanism may include two second detection elements 62. One second detection element 62 can be used to detect the position of a baffle assembly 40, and the other second detection element 62 can be used to detect the position of another baffle assembly 40. That is, the second opening end 203 of the feed pipe assembly 20 can be determined to be in a closed state 2031 or an open state 2032 by the detection results of the two second detection elements 62. In the embodiment, the detection results of the two second detection elements 62 can be synchronized.

[0091] In other embodiments, the feeding mechanism may include a second detection element 62, which can determine the opening and closing state of the second opening end 203 by detecting the position of a baffle assembly 40.

[0092] Of course, in other embodiments, the feeding mechanism may also include three or five equal numbers of second detection elements 62, and the number of second detection elements 62 may be the same as the number of baffle assemblies 40.

[0093] In this embodiment, the two second detection elements 62 may have the same structure and the installation positions of the two second detection elements 62 may be symmetrical. A detailed description will be given using one of the second detection elements 62 as an example.

[0094] In some embodiments, the second detection element 62 may be a pressure sensor. The second detection element 62 may be fixedly mounted on the outer wall of the feed tube assembly 20, and may be located on the movement path of the second structural segment 402. When the second open end 203 of the feed tube assembly 20 is in a closed state 2031, the baffle assembly 40 is in a direction perpendicular to gravity, and the baffle assembly 40 will not contact the second detection element 62. In this state, the second detection element 62 may output a third detection signal, indicating that the second open end 203 of the feed tube assembly 20 is in a closed state 2031.

[0095] When the baffle assembly 40 rotates forward relative to the feed pipe assembly 20 to open the second opening end 203 of the feed pipe assembly 20, the eccentric block 42 in the second structural section 402 can apply pressure to the second detection element 62, thereby triggering the second detection element 62 to output a fourth detection signal, indicating that the second opening end 203 of the feed pipe assembly 20 is in the open state 2032. It is understood that the force-bearing part of the second detection element 62 can have a certain extension height to meet the path requirements of the eccentric block 42 in different positions, ensuring that the second detection element 62 can be triggered in the corresponding state whenever the eccentric block 42 is in any mounting position 4301.

[0096] In other embodiments, the second detection element 62 may also be an infrared sensor or a Hall sensor. It is understood that when the second detection element 62 is a Hall sensor, a magnetic element that cooperates with the Hall sensor may be provided on the second structural segment 402 of the baffle assembly 40.

[0097] In this embodiment, the second detection element 62 can be electrically connected to the controller, and the controller can determine the switching state of the second opening end 203 based on the detection signal sent by the second detection element 62.

[0098] During the use of the feeding mechanism, when the first detection element 61 outputs a first detection signal and the second detection element 62 outputs a third detection signal, it indicates that there is material in the feeding bin 10 and the second open end 203 of the conveying pipe assembly 20 is in a closed state 2031. In this case, the negative pressure supply structure connected to the negative pressure chamber 21 can be opened to draw negative pressure from the negative pressure chamber 211 (even if the negative pressure chamber 211 is in a negative pressure state). When the negative pressure chamber 211 is in a negative pressure state, it can provide an attractive force for the material in the feeding bin 10, driving the material out of the feeding bin 10 and into the conveying pipe assembly 20 to be conveyed to the receiving bin 30, thereby speeding up the feeding speed and improving the feeding efficiency. At the same time, it can also reduce the overflow of material from the assembly gap at the connection between the conveying pipe assembly 20 and the feeding bin 10, reduce the dust concentration in the surrounding operating environment, improve the operating environment, and ensure the health of the operators. Understandably, in this state, the baffle assembly 40 closes the second opening end 203 of the conveying pipe assembly 20, which facilitates the negative pressure supply structure to draw negative pressure from the negative pressure chamber 21, thereby improving the efficiency of drawing negative pressure and thus improving the overall working efficiency of the feeding mechanism.

[0099] When the first detection element 61 outputs the first detection signal and the second detection element 62 outputs the fourth detection signal, it indicates that there is material in the feeding hopper 10 and the second opening end 203 of the conveying pipe assembly 20 is in the open state 2032. Under these circumstances, the controller can control the negative pressure supply structure to close, and the negative pressure chamber 211 is in a normal pressure state. The feeding hopper 10 can normally supply material to the receiving hopper 30 through the conveying pipe assembly 20 without the need for additional flow assistance, thereby achieving energy-saving effects.

[0100] The embodiment also provides a material processing device, which may include a negative pressure supply structure (not shown) and a feeding mechanism provided in the embodiment. The negative pressure supply structure can be connected to the negative pressure source interface 212 of the conveying pipe assembly.
