Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery material production, and in particular to a conveyor for conveying new energy lithium battery materials. Background Art

[0002] The positive and negative electrode materials of lithium batteries often exist in the form of particles or powders. The properties of these particles / powders have a significant impact on the performance of lithium-ion batteries. First, the morphology and size of the particles / powders affect the diffusion path and diffusion resistance of lithium ions, as well as the contact area between the active material and the electrolyte, thereby affecting the electrochemical performance of lithium-ion batteries. In addition, spherical particles provide a larger contact area, increasing the active material content in the electrode. Second, the particle size distribution has a direct impact on the packing of electrode material particles.

[0003] However, the transportation of these battery materials is relatively troublesome. In order to prevent air pollution or harm to the human body, pneumatic conveying devices are usually used to transport these materials. However, these battery materials flow in the pipeline under the action of airflow. As the flow time increases, the materials continuously hit the inner wall of the pipeline with irregular motion, gradually causing wear on the inner wall of the pipeline, so that some metal debris will fall from the inner wall of the pipeline and flow with the material, which will eventually affect the conveying purity of these materials.

[0004] Therefore, we proposed a conveyor for transporting new energy lithium battery materials to solve the above problems. Summary of the Invention

[0050] The disclosure below provides many different embodiments or examples for realizing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0051] like Figure 1As shown, the present invention provides a technical solution: a conveyor for conveying new energy lithium battery materials, comprising a base 1, a feeder 2, a screening assembly, a drive structure 1 5, a drive structure 2 6 and a transmission structure 7. A fixing frame 3 is fixedly installed on the base 1 by bolts, and a PLC controller 31 is installed on the outer surface of one side of the fixing frame 3. A conveying pipe 12 is provided below the fixing frame 3, and the conveying pipe 12 is arranged along the length direction of the base 1, and a plurality of support seats are also installed between the conveying pipe 12 and the base 1 by bolts. An air pump 11 for providing airflow is connected to one end of the conveying pipe 12, and a connecting box 13 connected thereto is installed on the other end of the conveying pipe 12. A convex ring is welded on the outer surface of the end of the connecting box 13 away from the air pump 11, and a thread is provided on the inner surface of the convex ring so that the material collection can be assembled by threaded installation. The collecting bag / collection box is provided with a feeder 2 fixed by bolts on the outer surface of the conveying pipe 12. A material-dispensing plate 21 is rotatably arranged inside the feeder 2, and a rotating motor 1 is installed on the outer surface of the feeder 2. The rotating motor 1 drives and controls the material-dispensing plate 21. A screening assembly is slidingly arranged in the connecting box 13. The driving mechanism 1 5 is connected to the material-dispensing plate 21. The driving structure 2 6 is connected to the screening assembly and controls the reciprocating motion of the screening assembly. The transmission structure 7 is connected between the driving structure 1 5 and the driving structure 2 6, so that the alternating speed of the screening assembly can be directly controlled according to the dispensing speed of the material-dispensing plate 21. Two sets of cleaning structures 8 are also installed on the base 1 for cleaning the adsorbed metal debris. A chute is also provided on one side of the cleaning structure 8 on the base 1 to facilitate the falling and collection of the cleaned metal impurities.

[0052] It should be further explained that the material (powder or granular) enters the conveying pipe 12 through the feeder 2, and the pneumatic pump 11 is started to generate airflow in the conveying pipe 12, thereby driving the material to flow in the pipe. As the material continues to flow in the conveying pipe 12, the inner wall of the conveying pipe 12 is continuously impacted by the material. After a long time, metal debris will fall off the inner wall of the conveying pipe 12 and mix with the material and flow together. At the outlet of the conveying pipe 12, the screening component can be alternately moved back and forth to remove the mixed pipe wall debris through the adsorption effect, so as to improve the purity of the material.

[0053] like Figure 2-5 As shown, a square hole and a T-shaped hole are respectively provided on the top surface of the fixing frame 3, and a vertically arranged fixing plate 32 is installed on the top surface of the fixing frame 3 on one side of the square hole by bolts. A sub-controller 1 is installed on the vertical side wall of one side of the fixing plate 32, and the sub-controller 1 is connected to the PLC controller 31 through an electrical signal. An extension platform 33 is also installed on the side wall of the fixing frame 3 facing the feeder 2 by bolts.

[0054] The screening assembly includes a screening box 4, a screening plate 41, a second fixing seat 42, a connecting shaft 43 and a third fixing seat 44;

[0055] The screening box 4 is arranged in a rectangular parallelepiped structure, and two fixing seats 42 are provided and symmetrically installed on the top surface of the screening box 4, and a connecting shaft 43 is fixedly inserted between the two fixing seats 42, and a rack 431 arranged vertically upward is installed on the outer surface of the connecting shaft 43 by screws, and a contact sensor 1 (not shown in the figure) is embedded on the side wall surface of the fixing seat 42 facing the connecting seat, and the contact sensor 1 is connected to the PLC controller 31 through an electrical signal. The screening box 4 is provided with two symmetrically arranged mounting holes, and a screening plate 41 is installed at the middle position of the mounting hole by screws, and a number of screening holes are provided on the screening plate 41, and a magnet ring (not shown in the figure) is embedded on the circumferential surface of the screening hole, and a screen with a certain thickness ((the thickness is equal to the thickness of the mounting hole - the thickness of the screening plate 41) / 2) can be fixed on the two side surfaces of the screening plate 41 by screws. Figure 2 A plastic plate (not shown in the figure) is provided to reduce the thickness difference between the middle screening plate 41 and the outer surface of the screening box 4, so that only metal debris can be adsorbed by the magnet ring when passing through the screening hole, and cannot be adsorbed on the two side surfaces of the screening plate 41. A fixing seat 44 is also installed on the top surface of the connecting box 13 by bolts.

[0056] Among them, a discharge port connected to the conveying pipe 12 is opened in the connecting box 13, and the size of the discharge port is equal to the size of the screening plate 41. A solenoid valve 131 is also installed at the end of the connecting box 13 facing the conveying pipe 12 by screws. The opening and closing action of the solenoid valve 131 realizes the conduction between the conveying pipe 12 and the connecting box 13, and when the screening component is switched, the solenoid valve 131 is controlled to be closed by the PLC controller 31, so as to avoid affecting the material being taken away from the conveying pipe 12 during switching. After the switching is completed, the solenoid valve 131 is opened again, and the switching time of the screening component can be completed between 2-3 seconds.

[0057] It should be further explained that the reciprocating linear motion of rack 1 431 is controlled by the action of gear transmission, so that it drives the connecting shaft 43 to move and synchronously drives the screening box 4 to move and adjust. Whenever the fixed seat 2 42 moves to a position in contact with the outer surface of the connecting box 13, the contact sensor 1 on the fixed seat 2 42 is triggered. At this time, one of the screening plates 41 is located exactly in the middle position of the discharge port, and the other screening plate 41 is located outside the connecting box 13 and is arranged opposite to the cleaning structure 8 on the same side.

[0058] The second driving structure 6 includes a guide rail base 61, a movable base 62, a movable shaft 63, an adjustment gear 64, an adjustment rack 65, a rotating member 66, a rotating block 67 and a fixed rod 68;

[0059] The longitudinal section of the guide rail seat 61 is U-shaped, and the guide rail seat 61 is fixed between the side walls of the connecting box 13 and the fixed frame 3 by bolts. The movable seat 62 is arranged in a "U"-shaped structure and slides between the inner walls of the guide rail seat 61. A sliding rod 611 is provided through the movable seat 62 and is in sliding contact with it. The sliding rod 611 is fixedly installed between the side walls of the connecting box 13 and the fixed frame 3. A spiral guide groove is provided on the outer surface of the movable shaft 63. One end of the movable shaft 63 is fixed between the side walls of the movable seat 62 by an axial connection and is connected thereto as a whole, and a connecting groove is also provided on the end where the movable shaft 63 is connected to the movable seat 62.

[0060] A rotating sleeve 641 is provided between the inner walls of the fixed seat three 44 and is in rotational contact therewith. A limit ring 1 is connected to the outer surface of the rotating sleeve 641 and is synchronized with it. The limit ring 1 is always rotatably provided between the inner walls of the fixed seat three 44. One end of the rotating sleeve 641 is fixed to the adjusting gear 64 as a whole by screws, and a guide bolt (not shown in the figure) is fixed to the inner surface of the rotating sleeve 641 by screws. The guide bolt always slides and adjusts along the inner wall of the guide groove. When the guide bolt moves from one end of the guide groove to the other end, the adjusting gear 64 rotates exactly 360 degrees.

[0061] Among them, an annular electromagnet 441 is also installed on the side wall surface of the fixed seat three 44 facing the adjusting gear 64, and an external power supply (not shown in the figure) for controlling the start of the electromagnet 441 is installed on one side wall of the fixed seat three 44. The external power supply and the PLC controller are connected through electrical signals. One end of the rotating sleeve 641 passes through and is rotatably set between the inner walls of the electromagnet 441, and when the electromagnet 441 is in a working state, the rotating sleeve 641 and the electromagnet 441 can be connected as a whole by suction. In fact, after each switching of the screening component 4 (that is, when the contact sensor on this side is triggered), the PLC controller immediately controls the start of the external power supply, and causes the electromagnet 441 to lock and fix the state of the rotating sleeve 641, and then stops the external power supply when the next switching occurs.

[0062] It should be further explained that as the movable seat 62 moves linearly between the side walls of the guide rail seat 61, the movable shaft 63 is synchronously driven to move back and forth in the rotating shaft sleeve 641 along the horizontal direction. The guide groove uses the limiting and guiding effect of the guide bolt. When the movable shaft 63 makes a linear motion to one side, the guide bolt rotates along the trajectory of the guide groove and synchronously drives the rotating shaft sleeve 641 to rotate and adjust together. Then, during the reciprocating linear motion of the movable shaft 63, the forward and reverse rotation of the rotating shaft sleeve 641 is controlled according to the different motion directions, thereby driving the adjusting gear 64 to also achieve the forward and reverse rotation effects, thereby controlling the reciprocating movement and adjustment of the screening box 4.

[0063] A transmission gear 661 and a cam-shaped rotating member 66 are respectively provided on both sides of the fixed plate 32 for coaxial rotation (it should be noted that a rotation angle sensor is installed on the shaft connected to the two, which is not shown in the figure. The rotation angle sensor is mainly used to monitor its rotation angle, and the rotation angle sensor is connected to the PLC controller 31 through an electrical signal), and a locator 321 with an axial ring structure is also fixedly installed on the side wall of the fixed plate 32 facing the transmission gear 661, and the sub-controller 1 and the locator 321 are connected and controlled by wires.

[0064] A linkage handle 662 is rotatably provided on the other end of the rotating member 66 via an axis connection, and the other end of the linkage handle 662 is rotatably provided in a connecting groove at the end of the movable shaft 63 via an axis connection.

[0065] A connecting frame 37 is installed on the bottom wall of the fixing frame 3 below the square hole by bolts, a rotating block 67 is rotatably provided above the connecting frame 37, and a bevel gear 6 77 is rotatably provided below the connecting frame 37. The rotating block 67 and the bevel gear 6 77 are coaxially connected, and a piston shaft 671 is slidably provided between the inner walls of the rotating block 67, and an "L"-shaped connecting piece 672 is installed on one end of the piston shaft 671 by screws, and a spring is sleeved on the piston shaft 671 between the rotating block 67 and the connecting piece 672, and a protrusion (disc-shaped structure) connected to it is provided on the other end of the piston shaft 671, that is, the piston shaft 671 never separates from the rotating block 67.

[0066] Guide grooves are provided on the inner walls on both sides of the square hole, and sliders 681 are slidably arranged in the guide grooves. A fixing rod 68 is fixedly connected between the sliders 681 on both sides, and a connecting block 651 is slidably arranged on the fixing rod 68. The bottom wall of the connecting block 651 and the top wall of the connecting piece 672 are rotatably connected by a "T"-shaped axis. An adjusting rack 65 is installed on the top of the connecting block 651 by screws. The adjusting rack 65 slides and adjusts along the top surface of the fixing frame 3, and the movement trajectory of the adjusting rack 65 is rectangular.

[0067] Among them, distance sensors 38 are embedded on the inner walls on the other two sides of the square hole. The distance sensors 38 are connected to the PLC controller 31 through electrical signals, and the positions of the two distance sensors 38 are set on the side close to the position of the transmission gear 661.

[0068] It should be further explained that the rotation of the rotating block 67 is driven by the output of the bevel gear six 77. As the rotating block 67 rotates, the connecting piece 672 performs circular motion synchronously therewith, and the connecting block 651 always sticks to the four inner walls of the square hole and moves and adjusts together with the drive of the connecting piece 672, thereby synchronously driving the adjustment rack 65 to reciprocate and adjust. When the transmission gear one 661 is able to contact and engage with the adjustment rack 65, as the adjustment rack 65 moves linearly, it can control the circular motion of the transmission gear one 661, so that the rotating member 66 on the other side rotates synchronously, and then the reciprocating motion of the movable seat 62 is controlled through the linkage handle 662.

[0069] In the sliding process of the connecting block 651, as shown in FIG. Figure 4 As shown in the figure, the marks ad are four state points during the movement of the connecting block 651. The specific process is as follows:

[0070] When the connecting block 651 is located at position a shown in the figure, the distance value detected by the distance sensor 38 at this position is 0. At this time, the adjustment rack 65 is just as shown in the figure. Figure 4 As shown, the adjusting rack 65 is in meshing contact with the transmission gear 1 661. When the connecting block 651 moves from position a to position b, the positioner 321 stops working. During the linear movement of the connecting block 651, the adjusting rack 65 moves toward the side where the transmission gear 1 661 is located, thereby driving the rotation of the transmission gear 1 661.

[0071] When the connecting block 651 moves to position b as shown in the figure, the transmission gear 1 661 rotates 180 degrees, and the rotating member 66 also rotates 180 degrees. The connection point between the rotating member 66 and the linkage handle 662 is in the horizontal direction (that is, when the connecting block 651 is in position a as shown in the figure, the connection point between the rotating member 66 and the linkage handle 662 is still in the horizontal direction and is horizontally opposite to the position where it is currently stopped). At this time, the distance value detected by the distance sensor 38 on the side where position b is located is 0, and the positioner 321 is activated, firmly locking the shaft between the transmission gear 1 661 and the rotating member 66 by suction.

[0072] When the connecting block 651 moves from position b to position c as shown in the figure, the circular motion of the rotating block 67, the piston shaft 671 and the connecting piece 672 controls the connecting block 651 to slide against the inner wall of the square hole, thereby causing the adjusting rack 65 to move in a straight line away from the transmission gear 1 661 until it reaches position c. Subsequently, the connecting block 651 continues to move from position c to position d. During this process, the connecting block 651 also drives the adjusting rack 65 to make a straight line motion toward the side where position d is located.

[0073] When the connecting block 651 moves from the position d to the position a shown in the figure, the connecting block 651 drives the adjusting rack 65 to make a linear motion toward the side where the transmission gear 1 661 is located. When the connecting block 651 moves to the position a, the distance value detected by the distance sensor 38 at this position is 0 again. At this time, the positioner 321 stops, and the adjusting rack 65 moves again to a state of meshing contact with the transmission gear 1 661.

[0074] like Figure 6-10 As shown, a cavity is provided inside the feeder 2, and a material-dispensing plate 21 is rotatably arranged between the inner walls of the cavity, and an output shaft 211 connected to the material-dispensing plate 21 is passed through the middle of the material-dispensing plate 21 as an integral part thereof, one end of the output shaft 211 is mounted on the output end of the rotating motor 1 as its output component, and a mounting seat integrally formed with the output shaft 211 (i.e., the diameter of the mounting seat is equal to the diameter of the output shaft 211) is fixed to the other end of the output shaft 211 by screws, and a magnetic column 212 and a magnetic ring 213 are mounted on the outer surface of the mounting seat by screws, and the magnetic column 212 is located in the middle position of the magnetic ring 213.

[0075] The driving structure 1 5 includes a bevel gear 1 51 , a bevel gear 2 52 , a bevel gear 3 53 , a bevel gear 4 54 and a connecting sleeve 55 ;

[0076] One end of the connecting sleeve 55 is fixedly mounted on the outer surface of the mounting base by screws, and a magnetic power supply is installed on the outer surface of the connecting sleeve 55. The magnetic power supply and the magnetic column 212 and the magnetic ring 213 can be individually controlled by wires, and the magnetic power supply is connected to the PLC controller 31 through electrical signals. The extension platform 33 is located below the connecting sleeve 55 and is arranged in rotational contact therebetween.

[0077] The output shaft 2 511 is fixedly installed on the end face of the bevel gear 1 51 facing the connecting sleeve 55 by screws, and the limit ring 2 is fixedly installed on the outer surface of the output shaft 2 511. The bevel gear 1 51 and the bevel gear 2 52 are engaged for transmission. The output shaft 2 511 and the limit ring 2 are both rotatably set between the inner wall of the connecting sleeve 55. The end face of the output shaft 2 511 located in the connecting sleeve 55 is in contact with the end face of the magnetic ring 213, and they can be connected as one by magnetic attraction.

[0078] The output shaft three 531 is fixedly installed on the end face of the bevel gear three 53 facing the connecting sleeve 55 by screws, and a limit ring three is fixedly installed on the outer surface of the output shaft three 531. The bevel gear three 53 is meshed with the bevel gear four 54 for transmission. The output shaft three 531 passes through the bevel gear one 51 and the output shaft two 511 and extends to the end face of the magnetic column 212 for rotation. The output shaft three 531 is rotatably set between the inner walls of the bevel gear one 51 and the output shaft two 511, and the limit ring three is rotatably set between the inner walls of the output shaft two 511. The output shaft three 531 and the magnetic column 212 can also be connected as a whole by magnetic attraction.

[0079] It should be further explained that the generation of current on the magnetic column 212 and the magnetic ring 213 is controlled by the magnetic power supply, so that the magnetic column 212 and the magnetic ring 213 can generate suction force separately. When there is suction force on the magnetic column 212, the magnetic column 212 and the output shaft three 531 are connected as one, and the bevel gear three 53 can rotate synchronously with the rotation of the output shaft one 211; when there is suction force on the magnetic ring 213, the magnetic ring 213 and the output shaft two 511 are connected as one, and the bevel gear one 51 can rotate synchronously with the rotation of the output shaft one 211. When there is no suction force on the magnetic column 212 or the magnetic ring 213, under the action of the limit ring two and the limit ring three, the output shaft three 531 and the output shaft two 511 can generate rotational contact, or the output shaft two 511 and the connecting sleeve 55 can also generate rotational contact.

[0080] When bevel gear 1 51 rotates, it can drive the synchronous shaft 1 75 to rotate through the meshing transmission with bevel gear 2 52 . When bevel gear 3 53 rotates, it can drive the external shaft and screw 1 751 to rotate through the meshing transmission with bevel gear 4 54 .

[0081] The transmission structure 7 includes a transmission gear 2 71 , a transmission gear 3 72 , a bevel gear 5 73 , a moving member 74 , a synchronization shaft 1 75 , a synchronization shaft 2 76 and a bevel gear 6 77 ;

[0082] A fixing plate 2 35 and a fixing plate 3 36 are installed between the inner walls of the fixing frame 3 by bolts, and a fixing seat 1 34 is also installed on the outer surface of the fixing frame 3 facing the bevel gear 2 52 by bolts. One end of the synchronization shaft 1 75 is connected and fixed to the bevel gear 2 52 as a whole, and the other end is rotatably set on the inner wall of the T-shaped hole, and a transmission gear 2 71 that rotates synchronously with it is also installed on the synchronization shaft 1 75, a positioning hole is provided on the transmission gear 2 71, and a through hole is provided on the synchronization shaft 1 75 along its length direction (contact sensors 2 are embedded on the opposite end walls on both sides of the through hole, not shown in the figure, the contact sensor 2 is connected to the PLC controller 31 through electrical signals, and the contact sensor 2 can only come into contact with the end face of the threaded sleeve 741 on the moving part 74), a screw 1 751 is rotatably set in the through hole, and one end of the screw 1 751 is connected to a screw fixed to it. The external shaft of the body passes through the fixed seat 34 and rotates with it. The external shaft is connected and fixed to the bevel gear 454 as one body. An "L"-shaped moving part 74 is slidably provided between the inner walls of the through hole. A threaded sleeve 741 fixed to it as one body is passed through the inner walls of the moving part 74. A screw 751 passes through the threaded sleeve 741 and cooperates with it for threaded transmission. A rotary motor is also installed on one side of the interior of the synchronous shaft 75. An electric suction cup 1 (not shown in the figure) is installed on the output end of the rotary motor. The end of the screw 751 close to the T-shaped hole is rotatably provided between the inner walls of the electric suction cup 1, and under the suction action of the electric suction cup 1, the screw 751 can rotate together with the electric suction cup 1 along with the rotary motor. It should be noted that the output direction of the rotary motor is unique, and the moving part 74 can only be moved and adjusted to the side away from the T-shaped hole under the action of the rotation of the driving screw 751.

[0083] One end of the moving member 74 facing the transmission gear 2 71 matches the positioning hole. When the end of the moving member 74 located in the through hole moves to the end of the through hole close to the transmission gear 2 71, the contact sensor 2 on this side is triggered, and at this time the moving member 74 passes through the positioning hole and the end of the moving member 74 contacts the inner wall of the T-shaped hole.

[0084] A synchronization shaft 2 76 is rotatably provided between the fixed plate 2 35 and the fixed plate 3 36, and a ring-shaped electric suction cup 2 is fixedly installed on the surface of the fixed plate 2 35 and the fixed plate 3 36 facing the transmission gear 3 72 by screws. The electric suction cup 2 is connected to the contact sensor 2 through an electrical signal. When the contact sensor 2 is triggered, it can control the electric suction cup 2 to perform a corresponding function. In addition, the electric suction cup 2 can also be directly controlled by the PLC controller 31. A transmission gear 3 72 that rotates synchronously with the synchronization shaft 2 is installed at a position near the fixed plate 2 35 on the synchronization shaft 2. The transmission gear 3 72 is always meshed with the transmission gear 2 71, and a bevel gear 5 73 that is synchronized with the synchronization shaft is installed on the other end of the synchronization shaft. A bevel gear 6 77 is meshed with one side of the bevel gear 5 73. The bevel gear 6 77 and the rotating block 67 are coaxially connected and are respectively rotatably provided below and above the connecting frame 37.

[0085] It should be further explained that, by first controlling the suction force generated on the magnetic column 212, the output shaft 3 531 is caused to rotate synchronously with the rotation of the output shaft 1 211, thereby driving the bevel gear 3 53 to rotate synchronously, and then driving the bevel gear 4 54 to rotate synchronously, and driving the external shaft and the screw 1 751 to rotate synchronously clockwise. As the screw 1 751 rotates and the displacement direction of the moving part 74 is restricted by the through hole, the moving part 74 can only move and adjust between the inner walls of the through hole in a straight line, and move to the side where the transmission gear 2 71 is located. When When the moving part 74 moves to the end of the side close to the transmission gear 2 71 in the through hole, the contact sensor 2 on this side is triggered. At this time, the two electric suction cups 2 stop working (that is, the synchronization shaft 2 76 can rotate), and the magnetic power supply to the magnetic column 212 is immediately stopped through the PLC controller 31, so that the suction force on the magnetic column 212 disappears. According to the different material-pickup speeds of the material-pickup plate 21, the time taken for the moving part 74 to contact the inner wall of the T-shaped hole is also different, thereby controlling the time for alternating replacement of the screening plate 41.

[0086] Subsequently, the PLC controller 31 is used to start the magnetic power supply to control the suction force of the magnetic ring 213, so that suction force is generated on the magnetic ring 213, thereby enabling the output shaft 2 511 to synchronously drive the rotation output of the bevel gear 1 51 with the rotation of the output shaft 1 211, and then the bevel gear 2 52 drives the rotation of the synchronization shaft 1 75 and the transmission gear 2 71. As the transmission gear 2 71 rotates, the transmission gear 3 72 rotates together, and drives the rotation output of the bevel gear 5 73 through the action of the synchronization shaft 2 76, and then synchronously controls the circular motion of the rotating block 67 through the action of the bevel gear 6 77. When the rotating member 66 rotates 180 degrees, the angle sensor is triggered. At this time, the PLC controller 31 immediately starts the two electric suction cups 2, so that the synchronization shaft 2 76 is locked and cannot continue to rotate. At the same time, the PLC controller 31 immediately stops the power supply of the magnetic power supply to the magnetic ring 213, so that the suction force on the magnetic ring 213 disappears.

[0087] Afterwards, the electric suction cup 1 on the rotary motor is started through the PLC controller 31, so that the screw 1 751 is connected to the rotary motor at this time. At the same time, the PLC controller also controls to eliminate the suction between the magnetic column 212 and the output shaft 3 531, that is, the screw 1 751 at this time can only rotate counterclockwise with the drive of the rotary motor. With the drive of the rotary motor, under the transmission action between the threaded sleeve 741 and the screw 1 751, the moving part 74 moves and adjusts to the side where the bevel gear 2 52 is located. When the end of the moving part 74 moves to the end of the through hole close to the position of the bevel gear 2 52, the end of the threaded sleeve 741 also triggers the contact sensor 2 on that side. At this time, the moving part 74 stops moving, and then, the next alternating replacement process of the screening plate 41 is repeated according to the set time interval.

[0088] like Figure 11 As shown, the cleaning structure 8 includes a fixing box 81, a second screw 82, a sliding seat 83, a mounting plate 84 and an inserting rod 841;

[0089] The fixed box 81 is arranged in a rectangular structure and is mounted on the base 1 by screws. A rotating motor 2 is installed on the outer surface of one end of the fixed box 81, and a screw 2 82 is installed on the output end of the rotating motor 2. The screw 2 82 is rotatably arranged between the inner walls of the fixed box 81, and a sliding seat 83 is slidingly arranged along the inner walls of the fixed box 81. The screw 2 82 penetrates the sliding seat 83 and cooperates with it through threaded transmission. A mounting plate 84 is mounted on the sliding seat 83 by screws, and a number of plug rods 841 are installed on the mounting plate 84 in a threaded connection manner. The distribution of the plug rods 841 is consistent with the distribution of the screening holes on the screening plate 41. When the screening plate 41 is moved out of the connecting box 13, the positions of the screening holes on the screening plate 41 are aligned one by one with the plug rods 841 on the mounting plate 84 on that side.

[0090] It should be further explained that every time the rotating member 66 rotates 180 degrees, one of the screen plates 41 on the screening box 4 is moved out of the connecting box 13, and the removed screen plate 41 is arranged opposite to the cleaning structure 8 on that side. Subsequently, the rotating motor 2 is started by the PLC controller 31, so that the control sliding seat 83 moves toward the side close to the screen plate 41. During the movement, the insertion rod 841 gradually approaches the screening hole and finally passes through the screening hole, pushing the metal impurities adsorbed in the screening hole out of the screening hole and falling into the inclined chute and sliding out. According to the movement distance set by the sliding seat 83, when it moves to the farthest distance, the PLC controller 31 immediately controls the rotating motor 2 to drive in reverse, and moves the insertion rod 841 out of the screening hole and stops after the sliding seat 83 is reset.

[0091] Working principle: Battery materials are fed into the feeder 2 and fed into the conveying pipe 12 through the material-dispensing plate 21. The battery materials are conveyed along with the battery materials under the action of the airflow through the pneumatic pump 11. The battery materials are discharged after passing through the connecting box 13. Before starting to convey, a collection bag or a collection box can be installed on the convex ring of the connecting box 13 by means of a threaded connection to facilitate the collection of these materials.

[0092] During the battery material transportation process, the magnetic column 212 is controlled to generate suction, so that the bevel gear 3 53 rotates synchronously with the output shaft 1 211 (the rotation direction of the output shaft 1 211 is determined by the rotation direction of the output shaft 1 211). Figure 6 After the first gear 73 is in gear, the second gear 73 is in gear, and the second gear 73 is in gear.

[0093] Rotating block 67 then starts to press Figure 5 As shown in the figure, the connecting block 651 moves in a counterclockwise direction. In the initial position, the connecting block 651 is located at Figure 4 At position a shown in FIG, after starting to move, the connecting block 651 moves in a straight line direction under the circular motion of the rotating block 67. Figure 4As shown, the position a moves to the position b (the positioner 321 stops working during this process, that is, there is no suction on the positioner 321 at this time), synchronously driving the adjustment rack 65 to make a linear motion to one side, and finally triggering the distance sensor 38 at the position b. At the same time, in this process, the transmission gear 1 661 is driven to rotate 180 degrees, and the rotating member 66 rotating coaxially with the transmission gear 1 661 also rotates 180 degrees accordingly, so that the movable seat 62 is pushed from the farthest position from the connecting box 13 to the closest position to the connecting box 13 through the action of the linkage handle 662, and then drives the adjustment gear 64 to rotate 360 ​​degrees, so that one of the screening plates 41 is exactly located in the discharge port of the connecting box 13;

[0094] Then, the connecting block 651 continues to move in a straight line direction under the circular motion of the rotating block 67. Figure 4 As shown, position b moves toward position c (when the distance value detected by the distance sensor 38 at position b reaches 0, the positioner 321 also enters the working state, i.e., at this time, there is suction on the positioner 321, thereby locking the state of the transmission gear 1 661 and the rotating member 66 and preventing them from moving further), and the adjustment rack 65 moves outward in a straight line toward the side away from the transmission gear 1 661, and stops moving toward this side when the connecting block 651 moves to position c;

[0095] Then, the connecting block 651 continues to move in a straight line under the circular motion of the rotating block 67. Figure 4 The position c shown moves toward the position d, which means that the adjustment rack 65 moves in the opposite direction of a→b. When the connecting block 651 moves to the position d, it stops moving toward the side.

[0096] Then, the connecting block 651 continues to move in a straight line direction under the circular motion of the rotating block 67. Figure 4 As shown, the position d moves toward the position a, that is, the adjustment rack 65 moves in the opposite direction of b→c. When the connecting block 651 moves to the position a again, the distance value detected by the distance sensor 38 at the position a is 0, and the adjustment rack 65 at this time moves again to the state of meshing contact with the transmission gear 1 661, that is, Figure 4 The state of the initial position shown in FIG. 2 is that, at this time, since the adjustment rack 65 restricts the transmission gear 1 661 , the positioner 321 stops working mode again (i.e., no suction is generated on the positioner 321 );

[0097] In the process of the connecting block 651 moving from a→b→c→d, the transmission gear 2 71 and the transmission gear 3 72 are always engaged and transmitted. When the connecting block 651 moves back to position a again, the bevel gear 1 51 stops outputting. At this time, the suction force on the magnetic ring 213 disappears. At the same time, the two electric suction cups 2 generate suction and firmly lock the synchronous shaft 2 76 to prevent accidental movement. Subsequently, before the next cycle arrives, the output shaft 1 211 no longer drives the bevel gear 1 51 or the bevel gear 3 53 to rotate, and the screening plate 41 located in the connecting box 13 can also It is capable of adsorbing metal impurities in the passing battery materials, and before the next cycle arrives, that is, when the bevel gear 1 51 stops outputting, the rotary motor and the electric suction cup 1 are started by the PLC controller 31, so that the screw 1 751 rotates with the drive of the rotary motor until the moving part 74 moves to the end of the through hole near the position of the bevel gear 2 52. The end face of the threaded sleeve 741 triggers the contact sensor 2 on this side, and then the electric push rod resets and stops. At the same time, the magnetic seat forms suction again and is connected to the moving part 74 as a whole.
