[0002] NdFeB thin sheets are a common form of NdFeB permanent magnet material. They are characterized by thin thickness (usually ranging from a few microns to a few millimeters) and strong magnetism, and have special applications in many fields.

[0003] The production of NdFeB sheets is a process in which various metals are mixed and smelted into alloys in a certain proportion. Each batch of products involves many types of metals during the batching process, and most of the batching is done through automated weight proportioning. For example, the existing technology uses a double-layer vibrating screen, with the upper vibrating screen screening out large materials and the lower vibrating screen supplementing the small materials. This method is combined with a floor scale to achieve material proportioning and thus realize automated weighing of the raw materials.

[0004] However, when weighing the raw materials in the above method, no matter whether the upper or lower vibrating screen is conveying the raw materials from the corresponding discharge hopper into the barrel, when the large or small materials in the barrel reach the specified weight, the vibrating screen stops conveying, but the raw materials in the discharge hopper continue to fall downward, resulting in inaccurate weighing ratio of the raw materials, affecting the subsequent production quality of NdFeB sheets; and when the raw materials need to be replaced, it is difficult to discharge and clean the raw materials on the discharge hopper at the same time through the vibration of the upper and lower vibrating screens alone, and manual cleaning of the upper and lower vibrating screens and the raw materials on the discharge hopper is required, which greatly reduces the degree of automation and cleaning effect of the automatic batching structure of raw materials for NdFeB sheet production when replacing raw materials for automatic batching.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] See Figure 1 and Figure 2 A raw material automatic batching structure for the production of NdFeB thin sheets includes a box body 1, a discharge adjustment mechanism 12, two discharge hoppers 6, a discharge mechanism 7, an end sealing mechanism 8 and a push vibration mechanism 9. A vibrating screen 1 2 and a vibrating screen 2 3 are provided in the box body 1. The vibrating screen 1 2 is provided with a circular sieve opening to filter small materials and convey large materials. The vibrating screen 2 3 is used to convey small materials to supplement differential materials. A floor scale 10 is provided on one side of the box body 1. A roller line 4 for conveying a barrel 11 is provided on the floor scale 10. A discharge port 5 is provided on the side of the box body 1 close to the roller line 4.

[0035] Vibrating screen 1 2 and vibrating screen 2 3 are both existing equipment used for vibrating and conveying large and small materials.

[0036] See Figure 1 The discharge adjustment mechanism 12 is installed on the vibrating screen 2 and is used to adjust the size of the outlet of the vibrating screen 2. The discharge adjustment mechanism 12 includes a lifting baffle that slides up and down and an electric slider that controls the lifting baffle (which is the existing technology and is not specifically shown in the figure).

[0037] See Figure 1 and Figure 2The two discharge hoppers 6 are installed on the discharge port 5, and the two discharge hoppers 6 are respectively installed below the outlets of the vibrating screen 1 2 and the vibrating screen 2 3; the discharge mechanism 7 is jointly provided at the outlets of the two discharge hoppers 6.

[0038] See Figure 1 、 Figure 4 and Figure 6 The end sealing mechanism 8 is installed on the side wall of the box body 1. The end sealing mechanism 8 includes two fixed support plates 80, which are connected to the box body 1 through a connecting rod 81. A blocking plate 1 82 and a blocking plate 2 83 are connected between the two fixed support plates 80 for sliding up and down. The blocking plate 1 82 and the blocking plate 2 83 are connected by an elastic buckle 84. A driving part for driving the blocking plate 2 83 is also provided on the box body 1. When the driving part drives the blocking plate 2 83, the blocking plate 2 83 cooperates with the blocking plate 1 82 and the elastic buckle 84. When weighing and discharging, the upper discharge hopper 6 is opened first, the upper discharge hopper 6 is closed, and the lower discharge hopper 6 is opened and closed at the same time.

[0039] It is particularly noted that: the floor scale 10 is provided with a weighing sensor for controlling the opening and closing of the vibrating screen 1 2 and the vibrating screen 2 3 and the driving of the driving unit. The weighing sensor is a prior art. The specific process of controlling the opening and closing of the vibrating screen 1 2 and the vibrating screen 2 3 and the driving of the driving unit will not be repeated. The specific execution results are as follows: when the total amount of large materials in the barrel 11 is reached, the weighing sensor controls the vibrating screen 1 2 to stop working, and at the same time controls the driving unit and the vibrating screen 2 3 to work. The driving unit drives the blocking plate 2 83 to move upward quickly to a specified distance. The blocking plate 2 83 pushes the blocking plate 1 82 upward through the elastic locking unit 84 to block the upper discharge hopper 6 and open the lower discharge hopper 6. At the same time, the vibrating screen 2 3 vibrates to transport small materials, and the small materials are transported from The discharge hopper 6 on the lower side is discharged; when the total amount of material in the barrel 11 is reached, the weighing sensor controls the vibrating screen 2 3 to stop vibrating, and at the same time controls the driving unit to drive the blocking plate 2 83 to continue to move upward, and the blocking plate 2 83 moves upward through the elastic locking part 84 and is tightly pressed against the bottom of the blocking plate 1 82. The upper and lower discharge hoppers 6 are both closed. At this time, the weighing sensors are also closed, and then the roller line 4 transports and removes the barrel 11, and then the next barrel 11 is placed. When the next barrel 11 reaches the specified position, the weighing sensor is turned on and the barrel 11 is weighed by the floor scale 10. Through the weighing weight of the barrel 11, the weighing sensor controls the driving unit to drive the blocking plate 2 83 through the elastic locking part 84 to drive the blocking plate 1 82 to move downward for reset.

[0040] When the materials are initially batched, the upper discharge hopper 6 is opened, the vibrating screen 2 vibrates to filter the small materials and convey the large materials, so that the large materials fall into the barrel 11. During the material dropping process, the floor scale 10 below the roller line 4 is weighed in real time. When the total amount of large materials in the barrel 11 is reached, the weighing sensor controls the vibrating screen 2 to stop working. At the same time, the driving part drives the blocking plate 2 83 to move upward quickly to the specified distance. The blocking plate 2 83 pushes the blocking plate 1 82 upward through the elastic locking part 84 to block the upper discharge hopper 6 and open the lower discharge hopper 6. At the same time, the vibrating screen 2 3 vibrates to convey the small materials, and the small materials are discharged from the discharge hopper 6 on the lower side, thereby preventing the large materials in the upper discharge hopper 6 from continuing to fall downward into the barrel 11 after the vibrating screen 2 stops vibrating due to the tilt of the discharge hopper 6 and the gravity of the large materials themselves, resulting in more large materials in the barrel 11 and inaccurate weighting of the raw materials.

[0041] During the discharge of small materials, the floor scale 10 below the roller line 4 is weighed in real time. When the total amount of material in the barrel 11 is reached, the weighing sensor controls the driving unit to drive the sealing plate 2 83 to continue to move up, and the vibrating screen 2 3 stops vibrating. At this time, the sealing plate 1 82 no longer moves, and the sealing plate 2 83 moves up through the elastic locking part 84 and is tightly pressed against the bottom of the sealing plate 1 82. The upper and lower discharge hoppers 6 are both closed. At this time, the weighing sensors are closed at the same time, and then the roller line 4 transports the barrel 11 to be removed, and then the next barrel 11 is placed. The sealing plate 1 82 and the sealing plate 2 83 are buckled through the elastic locking part 84, and the roller line 4 transports the barrel 11 to the next process.

[0042] The above process realizes the precise weighing when automatically proportioning the raw materials for the production of NdFeB sheets, and avoids the problem that during the weighing process, the weight in the barrel 11 has reached the specified weight, but the material in the discharge hopper 6 continues to fall downward under its own weight, resulting in errors in material weighing and affecting the accuracy of the overall raw material ratio.

[0043] When the next barrel 11 reaches the specified position, the weighing sensor is turned on and the barrel 11 is weighed by the floor scale 10. According to the weighing weight of the barrel 11, the weighing sensor controls the driving part to drive the sealing plate 2 83 to move downward through the elastic locking part 84, and the sealing plate 1 82 is driven to move downward. During this process, the discharge hopper 6 on the lower side is always blocked until the discharge hopper 6 on the upper side is opened, and the above-mentioned batching steps are repeated.

[0044] See Figure 1 and Figure 2 The pushing vibration mechanism 9 is installed between the two discharge hoppers 6 and the box body 1. The two discharge hoppers 6 cooperate with the top rod 72 through the discharge mechanism 7 and then come into contact with the vibrating screen 1 2 and the vibrating screen 2 3. When the discharge mechanism 7 is opened, the remaining material is discharged as the vibrating screen 1 2 and the vibrating screen 2 3 vibrate.

[0045] When the material needs to be replaced, the two discharging hoppers 6 cooperate with the vibrating mechanism 9 through the discharging mechanism 7 to contact the vibrating screen 1 2 and the vibrating screen 2 3, and open the discharging mechanism 7 to discharge the residual material as the vibrating screen 1 2 and the vibrating screen 2 3 vibrate, thereby realizing the integrated vibration discharge of the residual material in the vibrating screen 1 2 and the vibrating screen 2 3 and the two discharging hoppers 6, which greatly improves the convenience and efficiency of residual material discharge.

[0046] See Figure 1 The driving part includes a driving source (such as an electric slider, not shown in the figure) installed on the fixed support plate 80 for driving the blocking plate 2 83 to slide up and down.

[0047] See Figure 1 、 Figure 6 and Figure 8 The elastic locking portion 84 includes spring grooves 840 provided on the opposite surfaces of the two fixed support plates 80, and ear plates slidably connected to the spring grooves 840 are installed on the sealing plate 1 82 and the sealing plate 2 83, and a compression spring 841 is installed between the two ear plates opposite to each other. The top of the ear plate of the sealing plate 1 82 and the two sides of the lower end surface of the sealing plate 1 82 arranged along its width direction are both installed with partitions 842 that close the spring grooves 840. The partition 842 is used to prevent the discharged material from entering the spring grooves 840, and the top of the partition 842 on the ear plate of the sealing plate 1 82 slides through the spring grooves 840, and the side wall of the sealing plate 2 83 is provided with a connecting groove corresponding to the partition 842 on the sealing plate 1 82 and slidingly matched, and a snap-on assembly is installed between the sealing plate 1 82 and the sealing plate 2 83.

[0048] When the total amount of large material in the barrel 11 is reached, the weighing sensor controls the vibrating screen 2 to stop working. At the same time, the driving unit drives the blocking plate 2 83 to move upward quickly to the specified distance. When the blocking plate 2 83 moves upward, the compression spring 841 drives the blocking plate 1 82 to move upward. The blocking plate 1 82 blocks the outlet of the discharge hopper 6 for discharging large materials. At this time, the outlet of the discharge port 5 on the lower side is located between the blocking plate 1 82 and the blocking plate 2 83. Therefore, the outlet of the discharge port 5 on the lower side is in an open state. At this time, the ear plate on the blocking plate 1 82 conflicts with the top of the spring groove 840, and the top of the blocking plate 2 83 is aligned with the outlet of the discharge hopper 6 on the lower side. The vibrating screen 2 3 vibrates to transport the small material into the discharge hopper 6 on the lower side and transports the small material to the barrel 11 to supplement the differential material.

[0049] When the total amount of material in the barrel 11 is reached, the weighing sensor controls the driving unit to drive the sealing plate 2 83 to move up again, and the vibrating screen 2 3 stops vibrating. At this time, the ear plate on the ear plate of the sealing plate 1 82 is tightly pressed against the top of the spring groove 840, so the sealing plate 1 82 no longer moves. When the sealing plate 2 83 moves up, the compression spring 841 contracts, and the sealing plate 2 83 blocks the outlet of the discharge hopper 6 on the lower side until the sealing plate 2 83 is tightly pressed against the sealing plate 1 82. At this time, the clamping assembly connects the sealing plate 1 82 with the sealing plate 2 83, so that when the sealing plate 2 83 moves down, the sealing plate 1 82 and the sealing plate 2 83 are tightly pressed and move down, ensuring that the outlet of the discharge hopper 6 on the lower side always remains in a blocked state, avoiding the problem of inaccurate material ratio due to the small materials in the discharge hopper 6 being discharged first.

[0050] See Figure 1 、 Figure 6 and Figure 8 The clamping assembly includes receiving grooves on both sides of the blocking plate 82 arranged along its width direction. The receiving groove is located on the side of the blocking plate 82 close to the bottom. A clamping block 861 is installed in the receiving groove through the reset spring 860. The side of the clamping block 861 away from the reset spring 860 is inclined. A push plate 862 is installed on the ear plate connected to the blocking plate 83. The top of the push plate 862 is an inclined surface and a clamping groove 863 that matches the clamping block 861 is opened on the side close to the blocking plate 83. An unlocking piece is provided at the bottom of the spring groove 840, and a buffer piece is installed between the ear plate connected to the blocking plate 82 and the spring groove 840.

[0051] When the total amount of material in the barrel 11 is reached, the sealing plate 2 83 moves up and the compression spring 841 contracts. When the sealing plate 2 83 approaches the sealing plate 1 82, the inclined surface of the push plate 862 contacts the inclined surface of the block 861 and pushes the block 861 to squeeze the reset spring 860. The block 861 moves toward the receiving slot until the end of the block 861 is flush with the side wall of the sealing plate 1 82. The push plate 862 continues to move. When the slot 863 is aligned with the block 861, the block 861 is inserted into the slot 863 under the elastic force of the reset spring 860. At the same time, the sealing plate 1 82 and the sealing plate 2 83 are tightly attached and locked.

[0052] When the next barrel 11 reaches the specified position, the driving unit drives the sealing plate 2 83 to move downward, and the sealing plate 1 82 moves downward along with the sealing plate 2 83 through the engagement of the blocking block 861 and the slot 863, thereby realizing the function of first opening the upper discharge hopper 6 to discharge large materials, while keeping the outlet of the lower discharge hopper 6 always blocked.

[0053] When the ear plate on the second sealing plate 83 contacts the bottom of the spring groove 840, the unlocking piece pushes the block 861 out of the groove 863, and the first sealing plate 82 moves upward under the elastic force of the compression spring 841 to reset, so that the top of the first sealing plate 82 is aligned with the outlet of the upper discharge hopper 6, so as to repeat the above steps to work.

[0054] See Figure 8 The unlocking part includes an L-shaped push rod 864 installed at the bottom of the spring groove 840, and a through groove is provided on the push plate 862 and the ear plate connected thereto. The through groove passes through the card slot 863, and the horizontal section of the L-shaped push rod 864 slides into the through groove, and the end of the horizontal section of the L-shaped push rod 864 is rollingly connected with a ball.

[0055] When the ear plate on the second sealing plate 83 approaches the bottom of the spring groove 840, the ball on the L-shaped support rod 864 contacts the inclined surface of the block 861 and pushes the block 861 to move into the receiving groove until the block 861 is disengaged from the slot 863, thereby realizing the unlocking function.

[0056] See Figure 7 The buffer member includes an arc-shaped spring piece 865 connected to the ear plate of the sealing plate 82. The side wall of the spring slot 840 is provided with grooves evenly arranged from top to bottom. The arc-shaped spring piece 865 is plugged into and fitted with the multiple grooves one by one to slow down the upward movement of the sealing plate 82.

[0057] See Figure 1 、 Figure 2 and Figure 4 The sealing plate 1 82 and the sealing plate 2 83 are both provided with an inclined discharge port 820, and the lower end surface of the sealing plate 1 82 is installed with an extension plate 1 821. The discharge port 820 on the sealing plate 1 82 extends to the extension plate 1 821. A thin plate 823 is installed between the upper and lower discharge hoppers 6 and on the lower outer wall of the discharge hopper 6 on the lower side. The thin plate 823 is tightly attached to the side walls of the sealing plate 1 82 and the sealing plate 2 83. The thin plate 823 is used to prevent materials from flying into between the two discharge hoppers 6, so that the materials in the two discharge hoppers 6 can fall smoothly into the barrel 11.

[0058] See Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The discharging mechanism 7 includes a connecting tube 70 installed between the upper and lower discharge hoppers 6 and below the lower discharge hopper 6. The connecting tube 70 is connected to the inclined end of the discharge hopper 6. A flip plate 71 is rotatably connected to the connecting tube 70 to seal the top thereof. A top rod 72 is horizontally slidably connected to the connecting tube 70. The top rod 72 supports the lower end of the flip plate 71. The top rod 72 is horizontally slidably connected to the box body 1. The box body 1 is provided with an electric slider 2 (which is a prior art and not shown in the figure) that drives the two top rods 72 to move simultaneously.

[0059] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The pushing vibration mechanism 9 includes two upper and lower groups of pushing rods 90 hinged by torsion spring rods under the discharge port 5. Each group of pushing rods 90 is composed of pushing rods 90 symmetrically arranged along the width direction of the discharge port 5. The upper and lower groups of pushing rods 90 are respectively located below the outlets of vibrating screen 1 2 and vibrating screen 2 3. A push-pull rod 91 is fixedly installed on the end of the top rod 72 away from the flip plate 71. The end of the push-pull rod 91 away from the top rod 72 is slidably sleeved on the pushing rod 90 and is used to drive the pushing rod 90 to rotate and contact the corresponding discharge hopper 6.

[0060] When the material needs to be replaced for weighing and the residual material needs to be cleared, the electric slider 2 drives the two push rods 72 to move to the side away from the connecting cylinder 70. During the movement, the flip plate 71 flips along the hinge under the action of its own gravity, thereby opening the top of the connecting cylinder 70, so that the large and small materials in the upper and lower discharge hoppers 6 are discharged from the connecting cylinder 70 on the lower side. At the same time as the push rod 72 moves, the push rod 72 drives the push-pull rod 91 to rotate, and the push-pull rod 91 pushes the push rod 90 to rotate. The push rod 90 rotates and presses against the corresponding discharge hopper 6. When the vibrating screen 1 2 and the vibrating screen 2 3 vibrate, the large and small materials are transported to the corresponding discharge hopper 6. During the vibration process, the vibrating screen 1 2 and the vibrating screen 2 3 transmit the vibration force to the upper and lower discharge hoppers 6 through the push rod 90, so that the upper and lower discharge hoppers 6 vibrate along with the vibrating screen 1 2 and the vibrating screen 2 3, so as to facilitate rapid discharge of materials.

[0061] It should be noted that the vibrations of the vibrating screen 1 2 and the vibrating screen 2 3 are uniformly controlled to be turned on and off by another control switch.

[0062] See Figures 1-8The material that is in the upper hopper 6 is discharged from the lower hopper 6, thereby preventing the large material in the upper hopper 6 from falling into the barrel 11 due to the tilt of the discharge hopper 6 and the gravity of the large material itself after the vibrating screen stops vibrating, resulting in more large material in the barrel 11 and causing the problem of inaccurate weight distribution of raw materials.

[0063] During the discharge of small materials, the floor scale 10 below the roller line 4 is weighed in real time. When the total amount of material in the barrel 11 is reached, the weighing sensor controls the driving unit to drive the sealing plate 2 83 to continue to move up, and the vibrating screen 2 3 stops vibrating. At this time, the sealing plate 1 82 no longer moves, and the sealing plate 2 83 moves up through the elastic locking part 84 and is tightly pressed against the bottom of the sealing plate 1 82. The upper and lower discharge hoppers 6 are both closed. At this time, the weighing sensors are closed at the same time, and then the roller line 4 transports the barrel 11 and removes it. After that, the next barrel 11 is placed, and the sealing plate 1 82 and the sealing plate 2 83 are buckled through the elastic locking part 84, and the roller line 4 transports the barrel 11.

[0064] When the next barrel 11 reaches the specified position, the weighing sensor is turned on and the barrel 11 is weighed by the floor scale 10. According to the weighing weight of the barrel 11, the weighing sensor controls the driving part to drive the sealing plate 2 83 to move downward through the elastic locking part 84, and the sealing plate 1 82 is driven to move downward. During this process, the discharge hopper 6 on the lower side is always blocked until the discharge hopper 6 on the upper side is opened, and the above-mentioned batching steps are repeated.

[0065] When the material needs to be replaced, the two discharging hoppers 6 cooperate with the vibrating screen 1 2 and the vibrating screen 2 3 through the discharging mechanism 7 and the top rod 72 to conflict with the vibrating screen 1 2 and the vibrating screen 2 3, and open the discharging mechanism 7 to discharge the residual material as the vibrating screen 1 2 and the vibrating screen 2 3 vibrate, thereby realizing the integrated vibration discharge of the residual material in the vibrating screen 1 2 and the vibrating screen 2 3 and the two discharging hoppers 6, which greatly improves the convenience and efficiency of residual material discharge.
