Description

Technical Field

[0001] This utility model relates to the field of NdFeB sintering technology, specifically to an automated NdFeB powder feeding production line. Background Technology

[0002] Neodymium iron boron (NdFeB) is a magnetic material and the strongest known type of permanent magnet. NdFeB can be divided into sintered NdFeB and bonded NdFeB. Because the magnetic properties of sintered NdFeB are far superior to those of bonded NdFeB, sintered NdFeB is widely used in electronics, electrical machinery, medical devices, toys, packaging, hardware machinery, aerospace, and other fields. In the sintering process, ground NdFeB powder is first loaded into a powder container, which is then suspended on a forming press. Finally, the powder is fed into the forming press for molding and pressing.

[0003] Currently, when molding and pressing neodymium iron boron powder, the material container is first hoisted onto the molding press manually, and then the material container is connected to the molding press inlet manually, and valves are opened and closed manually. The entire feeding process takes more than 10 minutes, resulting in low production efficiency. In addition, since neodymium iron boron powder is flammable, leakage may occur during manual operation, posing a great safety hazard to the operator. Summary of the Invention

[0004] The technical problem this invention aims to solve is that the current process of molding and pressing NdFeB powder involves manually handling the material containers and hoisting them onto the molding press, resulting in low production efficiency. The goal is to provide an automated NdFeB powder feeding production line where the entire handling and hoisting process is automatically operated by the production line's mechanical equipment, automatically hoisting the material containers onto the corresponding molding machines, replacing manual handling and hoisting of the material containers, and improving production efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] An automated feeding production line for neodymium iron boron powder includes a Z-axis automatic lifting mechanism for lifting and lowering a material container; several Y-axis lifting mechanisms, each equipped with a forming machine, wherein in operation, the material container is connected to the corresponding forming machine; and an X-axis transport mechanism for transporting the material container located on the Z-axis automatic lifting mechanism to the top of the corresponding Y-axis lifting mechanism.

[0007] The beneficial effects of this utility model are that by setting an automatic Z-axis lifting mechanism to raise and lower the material tank, it is easy for the X-axis conveying mechanism to connect with the material tank, and for the X-axis conveying mechanism to move the material tank above the corresponding Y-axis lifting mechanism, so that the material tank is in contact with the corresponding forming material tank. This allows the powder in the material tank to be transported to the forming material tank on the corresponding Y-axis lifting mechanism, and then the NdFeB powder is pressed into the desired shape by the forming machine. The entire handling and hoisting process is automatically operated by the mechanical equipment of the production line, realizing the automatic hoisting of the material tank onto the corresponding forming machine, replacing manual handling and hoisting of the material tank, and improving production efficiency.

[0008] In some embodiments, the Z-axis automatic lifting mechanism includes a Z-axis vertical frame, a material tank support, a guide plate, a gear, and a rack. The material tank is fixedly connected to the material tank support. A material tank lifting motor is fixedly connected to the bottom of the Z-axis vertical frame. The gear is mounted on the output shaft of the material tank lifting motor. The rack and the guide plate are both vertically arranged on the inner side wall of the Z-axis vertical frame and located on one side of the material tank support. The rack meshes with the gear. A slider is provided on the side wall of the material tank support, and the slider is slidably connected to the guide plate. By setting a Z-axis vertical frame and providing a guide plate and rack on the inner side of the Z-axis vertical frame, it is convenient to drive the gear to rotate when the lifting motor rotates. Through the meshing transmission of the gear and rack, the material tank support is raised and lowered along the inner side of the Z-axis vertical frame, thereby realizing the raising and lowering of the material tank installed on the material tank support. In specific operation, a forklift is used to install the material tank and the material tank support on the Z-axis vertical frame, and then the lifting motor and the material tank are raised and lowered synchronously through the transmission structure.

[0009] In some embodiments, the X-axis conveying mechanism includes a crossbeam, a moving trolley, and a material can holder clamping mechanism. The material can holder clamping mechanism is fixedly connected to the bottom of the moving trolley, and the top of the moving trolley is slidably connected to the crossbeam. The crossbeam is equipped with the same number of proximity switches as the Y-axis lifting mechanisms. The crossbeam is located above several Y-axis lifting mechanisms arranged side by side. The material can is mounted on the material can support. In the working state, the material can holder clamps onto the material can support, and the moving trolley drives the material can support to slide along the crossbeam to stop above the corresponding Y-axis lifting mechanism. By providing the same number of proximity switches as the Y-axis lifting mechanisms on the crossbeam, the moving trolley can easily drive the material can support to the corresponding proximity switch. The control terminal then issues a stop command to the drive motor, causing the moving trolley to stop at the corresponding position, ensuring that the powder in the material can is accurately released onto the corresponding molding press.

[0010] In some embodiments, the material tank rack clamping mechanism includes a clamping cylinder, two gripper rods, several connecting rods, and at least four grippers. One end of each gripper is fixedly connected to a corresponding gripper rod. The free end of the piston rod of the clamping cylinder is connected to one of the gripper rods. The two ends of the connecting rods are respectively connected to a pair of grippers located on the two gripper rods. In the working state, the piston rod of the clamping cylinder extends and drives a gripper rod connected to it to rotate. The grippers located on the two gripper rods rotate in opposite directions, and the free ends of the grippers are clamped on the material tank rack. By fixing one end of the gripper to the corresponding gripper rod and connecting the free end of the piston rod of the gripping cylinder to one of the gripper rods, and connecting the two ends of the connecting rod to a pair of grippers located on the two gripper rods respectively, it is convenient that during operation, the piston rod of the gripping cylinder extends to drive the gripper rod connected to it to rotate, and the grippers on the two gripper rods rotate in opposite directions. The free ends of the grippers are clamped on the material tank support, so that the material tank support clamping mechanism clamps and connects the material tank support to the moving trolley. When it is necessary to release the material tank support, the piston rod of the gripping cylinder is retracted, causing the grippers to rotate in opposite directions, thereby releasing the free ends of the grippers from the material tank support.

[0011] In some embodiments, the connecting rods include at least four, the fixed end of the gripper is provided with an inclined portion, the inclined portion is inclined toward the inner side of the can holder clamping mechanism, two connecting rods are arranged in an X-shape to form a pair of connecting rods, and each pair of grippers is provided with a pair of connecting rods on the inclined portion, the connecting rods are all connected to the inclined portion of the corresponding gripper, and the gripper rod is fixedly connected to the inclined portion. By providing an inclined portion at the fixed end of the gripper and inclining it toward the inner side of the can holder clamping mechanism, the clamping force of the gripper can be improved. Furthermore, by arranging two connecting rods in an X-shape to form a pair of connecting rods, and providing a pair of connecting rods on the inclined portion of each pair of grippers, it is convenient to apply opposing pulling forces to the corresponding pair of grippers through the X-shaped connecting rods, so that the free end of the gripper can be kept clamped to the can holder for a long time.

[0012] In some embodiments, the material tank rack clamping mechanism includes a mounting plate and a rotating arm. The two sides of the mounting plate are hinged to the corresponding gripper bars via a connecting structure. The clamping cylinder is fixedly connected to the mounting plate. One end of the rotating arm is fixedly connected to a gripper bar, and the other end is connected to the free end of the piston rod of the clamping cylinder. Both the clamping cylinder and the rotating arm are inclined and tilted towards each other. The mounting plate is fixedly connected to the bottom of the moving trolley. By providing a rotating arm and inclining both the clamping cylinder and the rotating arm towards each other, the clamping force of the grippers can be improved.

[0013] In some embodiments, the Y-axis lifting mechanism includes a lifting motor, two lifting frames, two drive shafts, and two screws. The output shaft of the lifting motor is equipped with input conical teeth, and one end of each of the two drive shafts is equipped with output conical teeth. The two output conical teeth are located symmetrically on both sides of the input conical teeth and mesh with them. The other ends of the two drive shafts are connected to the corresponding screws via a transmission structure. The bottom of each lifting frame is screwed onto the corresponding screw. In operation, the lifting motor rotates forward or reverse, raising or lowering the lifting frame. This allows the lifting motor to rotate forward or reverse during operation, thereby driving the corresponding drive shaft to rotate forward or reverse. The torque of the drive shaft is then transmitted to the screws via the transmission structure, causing the screws to rotate forward or reverse, which in turn increases or decreases the distance between the two bottoms of the lifting frame connected to the screw, thus lowering or raising the lifting frame.

[0014] In some embodiments, the Y-axis lifting mechanism further includes a support base, which is fixedly connected to the top of the lifting frame. A through hole is provided in the middle of the support base, through which the material tank support passes. Several bottom support cylinders and swing cylinders are provided on the support base. A support block is provided at the free end of the piston rod of the bottom support cylinder, and a swing rod is provided at the free end of the piston rod of the swing cylinder. In the working state, the support block supports the bottom of the crossbeam of the material tank support, and the free end of the swing rod abuts against the outside of the material tank. By fixing the support base to the top of the lifting frame, it is easy to lift and lower the support base through the lifting frame. Several bottom support cylinders and swing cylinders are also provided on the support base. A support block is provided at the free end of the piston rod of the bottom support cylinder, and a swing rod is provided at the free end of the piston rod of the swing cylinder. When it is necessary to place the material tank on the support base, the support block lifts it to the bottom of the crossbeam of the material tank support, so that the material tank support is kept at the set height. The free end of the swing rod abuts against the outside of the material tank to position the material tank, prevent the material tank from shifting on the material tank support, and ensure that the material tank and the forming material tank are in contact.

[0015] In some embodiments, the Y-axis lifting mechanism further includes a valve stem, a valve motor, and a valve stem locking structure. The ball valve end of the valve stem is connected to the inner cavity of the discharge pipe section of the conveying tank. The output shaft of the valve motor is connected to the valve stem, and the valve stem locking structure is slidably connected to the stem portion of the valve stem. The valve stem is rotated by the valve motor, thereby automatically opening and closing the discharge port of the conveying tank.

[0016] In some embodiments, the valve stem locking structure includes a locking block, a valve bracket, a base plate, and a motor cylinder. The valve bracket is radially slidably connected to the base plate. The valve motor is fixedly connected to the bottom of a transfer bracket, which is slidably connected to the inner top of the valve bracket. The motor cylinder is fixedly connected to the valve bracket, and the free end of the piston rod of the motor cylinder is connected to the transfer bracket. The locking block is connected to the output shaft of the valve motor and is slidably connected to the stem portion of the valve stem. This allows the generator mounted on the valve bracket to move synchronously when the valve bracket slides to a position close to the valve stem during operation. This causes the locking block mounted on the output shaft of the valve motor to radially abut against the valve stem, restricting radial movement of the valve stem. The motor cylinder then drives the transfer bracket to slide, causing the valve motor connected to the transfer bracket to move synchronously. The movement of the valve motor causes the locking block to move along the length of the valve stem, resulting in the locking block abutting against the free end of the valve stem, restricting further movement of the valve stem along its length, thus maintaining the ball valve in its set position.

[0017] In some embodiments, the Y-axis lifting mechanism further includes two docking blocks and two docking cylinders. The molding machine is provided with a molding machine feed pipe. The free ends of the piston rods of the two docking cylinders are respectively connected to the outer sides of the corresponding docking blocks. The inner sides of the docking blocks are each provided with arc-shaped grooves. In the working state, the top of the molding machine feed pipe and the bottom of the conveying tank discharge pipe section of the conveying tank form a mating part, and the arc-shaped groove abuts against the outer periphery of the mating part. By providing two docking cylinders and connecting the free ends of the piston rods of the two docking cylinders to the outer sides of the corresponding docking blocks, and by providing arc-shaped grooves on the inner sides of the docking blocks to mate with the outer periphery of the mating part where the top of the molding machine feed pipe and the bottom of the conveying tank discharge pipe section of the conveying tank meet, the top of the molding machine feed pipe and the bottom of the conveying tank discharge pipe section of the conveying tank are docked, facilitating the smooth entry of powder into the molding tank and preventing powder leakage.

[0018] In some embodiments, grooves are provided on the inner sides of the two mating blocks, and protrusions are provided on the outer periphery of the top of the molding machine feed pipe and the outer periphery of the bottom of the conveying tank discharge pipe section. The protrusions constitute the mating parts, and in the working state, the two protrusions are engaged in the grooves. By providing grooves on the inner sides of the mating blocks and providing protrusions on the outer periphery of the top of the molding machine feed pipe and the bottom of the conveying tank discharge pipe section, it is easy to engage the two protrusions in the grooves, further limiting the top of the molding machine feed pipe and the bottom of the conveying tank discharge pipe section, further improving the mating accuracy between the top of the molding machine feed pipe and the bottom of the conveying tank discharge pipe section, thereby preventing the leakage of flammable NdFeB powder and ensuring the safety of the production site.

[0019] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0020] 1. The entire handling and hoisting process is automated by the production line's mechanical equipment, which automatically hoists the material tanks onto the corresponding molding machines, replacing manual handling and hoisting of the material tanks and improving production efficiency.

[0021] 2. The same number of proximity switches as the Y-axis lifting mechanism are installed on the cross frame, so that the moving trolley can drive the material tank rack to the corresponding proximity switch. The control terminal sends a stop command to the drive motor, so that the moving trolley stops at the corresponding position, ensuring that the powder in the material tank can be accurately released to the corresponding molding press.

[0022] 3. The piston rod of the clamping cylinder extends and drives a clamping claw rod connected to it to rotate. The clamping claws on the two clamping claw rods rotate in opposite directions. The free ends of the clamping claws are clamped on the material tank support, so that the material tank support clamping mechanism clamps and connects the material tank support to the moving trolley. When it is necessary to release the material tank support, the piston rod of the clamping cylinder is retracted, causing the clamping claws to rotate in opposite directions, thereby releasing the free ends of the clamping claws from the material tank support.

[0023] 4. The fixed end of the gripper is provided with an inclined part and tilted towards the inside of the material tank rack clamping mechanism, which can improve the clamping force of the gripper. The two connecting rods are also arranged in an X shape to form a pair of connecting rods. Each pair of grippers is provided with a pair of connecting rods on the inclined part, so that the X-shaped connecting rods can apply opposing pulling forces to the corresponding pair of grippers, so that the free end of the gripper can be kept clamped to the material tank rack for a long time.

[0024] 5. A groove is provided on the inner side of the docking block, and protrusions are provided on the outer periphery of the top of the molding machine feed pipe and the outer periphery of the bottom of the material tank discharge pipe section. This facilitates the further limiting of the top of the molding machine feed pipe and the bottom of the material tank discharge pipe section by engaging the two protrusions in the groove. This further improves the docking accuracy between the top of the molding machine feed pipe and the bottom of the material tank discharge pipe section, thereby preventing the leakage of flammable NdFeB powder and ensuring the safety of the production site.

[0045] Example

[0046] See Figures 1-13 This embodiment provides an automated feeding production line for neodymium iron boron powder, including a Z-axis automatic lifting mechanism 10 for lifting and lowering a material tank 11; several Y-axis lifting mechanisms 20, each equipped with a forming machine 23, wherein in operation, the material tank 11 is connected to the corresponding forming machine 23; and an X-axis transport mechanism 30 for transporting the material tank 11 located on the Z-axis automatic lifting mechanism 10 to the top of the corresponding Y-axis lifting mechanism 20.

[0047] See Figure 1 and Figure 13 The Z-axis automatic lifting mechanism 10 includes a Z-axis vertical frame, a material tank support 12, a guide plate 13, a gear 15, and a rack 14. The material tank 11 is fixedly connected to the material tank support 12. A material tank lifting motor is fixedly connected to the bottom of the Z-axis vertical frame. The gear 15 is mounted on the output shaft of the material tank lifting motor. The rack 14 and the guide plate 13 are both vertically arranged on the inner side wall of the Z-axis vertical frame and located on one side of the material tank support 12. The rack 14 meshes with the gear 15. A slider is provided on the side wall of the material tank support 12. The slider is slidably connected to the guide plate 13. By setting a Z-axis vertical frame and installing a guide plate 13 and a rack 14 on the inner side of the Z-axis vertical frame, it is convenient to drive the gear 15 to rotate when the lifting motor 221 rotates. Through the meshing transmission of the gear 15 and the rack 14, the material tank support 12 is raised and lowered along the inner side of the Z-axis vertical frame, thereby realizing the raising and lowering of the material tank 11 installed on the material tank support 12. In specific operation, the material tank 11 and the material tank support 12 are installed on the Z-axis vertical frame by a forklift, and then the material tank support 12 and the material tank 11 are raised and lowered synchronously by the lifting motor 221 and the transmission structure.

[0048] See Figure 1 , Figure 2 and Figure 7The X-axis conveying mechanism 30 includes a crossbeam 31, a moving trolley 34, and a tank rack clamping mechanism 35. The tank rack clamping mechanism 35 is fixedly connected to the bottom of the moving trolley 34, and the top of the moving trolley 34 is slidably connected to the crossbeam 31. The crossbeam 31 is equipped with the same number of proximity switches 33 as the Y-axis lifting mechanisms 20. The crossbeam 31 is located above several Y-axis lifting mechanisms 20 arranged side by side. The conveying tank 11 is mounted on the tank support 12. Slide rails 32 are provided on both sides of the bottom of the crossbeam 31, and rollers are provided on the bottom of the trolley. The rollers are slidably connected to the slide rails 32. In the working state, the tank rack clamping mechanism 35 clamps onto the tank support 12, and the moving trolley 34 drives the tank support 12 to slide along the crossbeam 31 until it stops above the corresponding Y-axis lifting mechanism 20. By installing proximity switches 33 on the crossbeam 31 in the same number as the Y-axis lifting mechanism 20, the moving trolley 34 can drive the material tank rack to the corresponding proximity switch 33. The control terminal then issues a stop command to the drive motor, causing the moving trolley 34 to stop at the corresponding position. The proximity switches 33 can be inductive, capacitive, Hall effect, or AC / DC type. The cables connecting the drive motor and the control terminal are all housed within the cable chain.

[0049] Specifically, the mobile trolley 34 also includes a trolley motor and a trolley drive shaft 222. A drive sprocket is mounted on the output shaft of the trolley motor. The trolley drive shaft 222 is rotatably connected to the trolley support via bearings. The trolley drive shaft 222 is horizontally positioned and has a driven sprocket mounted on it. The drive sprocket and the driven sprocket are driven by a chain. Rollers are fixedly connected to both ends of the trolley drive shaft 222 and located at the bottom of the trolley support. Two additional rollers are rotatably connected to the bottom of the trolley support.

[0050] See Figure 7 Specifically, the lifting frame 22 includes two, and the lifting frame 22 is composed of multiple long strip plates hinged at their ends, so that the top and bottom of the lifting frame 22 are provided with two connecting parts, thereby realizing the adjustable distance between the two bottoms, and thus achieving the lifting effect.

[0051] See Figures 3-5The material tank rack clamping mechanism 35 includes a clamping cylinder 38, two gripper rods 371, several connecting rods 36, and at least four grippers 372. One end of each gripper 372 is fixedly connected to a corresponding gripper rod 371. The free end of the piston rod of the clamping cylinder 38 is connected to one of the gripper rods 371. The two ends of the connecting rods 36 are respectively connected to a pair of grippers 372 located on the two gripper rods 371. In the working state, the piston rod of the clamping cylinder 38 extends and drives the gripper rod 371 connected to it to rotate. The grippers 372 located on the two gripper rods 371 rotate in opposite directions, and the free ends of the grippers 372 are clamped on the material tank support 12. By fixing one end of the gripper 372 to the corresponding gripper rod 371, and connecting the free end of the piston rod of the clamping cylinder 38 to one of the gripper rods 371, and connecting the two ends of the connecting rod 36 to a pair of grippers 372 located on the two gripper rods 371 respectively, it is convenient that during operation, the piston rod of the clamping cylinder 38 extends to drive the gripper rod 371 connected to it to rotate, and the grippers 372 located on the two gripper rods 371 rotate in opposite directions. The free ends of the grippers 372 are clamped on the material tank support 12, so that the material tank support clamping mechanism 35 clamps and connects the material tank support 12 to the moving trolley 34. When it is necessary to release the material tank support 12, by retracting the piston rod of the clamping cylinder 38, the grippers 372 rotate in opposite directions, thereby releasing the free ends of the grippers 372 from the material tank support 12. Specifically, the free end of the gripper 372 is provided with a hook 3721, and the inner side of the hook 3721 is provided with an anti-slip layer, which contacts the material tank support 12. The anti-slip layer can be made of soft materials such as rubber or silicone.

[0052] See Figures 3-4 The connecting rods 36 include at least four. The fixed end of the gripper 372 is provided with an inclined portion, which is inclined towards the inside of the material tank holder clamping mechanism 35. Two connecting rods 36 are arranged in an X-shape to form a pair of connecting rods 36. Each pair of grippers 372 has a pair of connecting rods 36 on its inclined portion. The connecting rods 36 are all connected to the inclined portion of the corresponding gripper 372. The gripper rod 371 is fixedly connected to the inclined portion. By providing an inclined portion at the fixed end of the gripper 372 and tilting it towards the inside of the material tank holder clamping mechanism 35, the clamping force of the gripper 372 can be improved. Furthermore, by arranging two connecting rods 36 in an X-shape to form a pair of connecting rods 36, and by providing a pair of connecting rods 36 on the inclined portion of each pair of grippers 372, it is convenient to apply opposing pulling forces to the corresponding pair of grippers 372 through the X-shaped connecting rods 36, so that the free end of the gripper 372 can be held with the material tank holder 12 for a long time. Specifically, the inclined portion of the gripper 372 has a groove, one end of the connecting rod 36 is fixed on the inclined portion of one of the grippers 372, and the other end of the connecting rod is slidably connected to the groove of the inclined portion of the other gripper 372 via a slider.

[0053] See Figures 3-5 The material tank rack clamping mechanism 35 includes a mounting plate 39 and a rotating arm 37. Both sides of the mounting plate 39 are hinged to the corresponding gripper rods 371 via a connecting structure. The clamping cylinder 38 is fixedly connected to the mounting plate 39. One end of the rotating arm 37 is fixedly connected to a gripper rod 371, and the other end is connected to the free end of the piston rod of the clamping cylinder 38. Both the clamping cylinder 38 and the rotating arm 37 are inclined and facing each other. The mounting plate 39 is fixedly connected to the bottom of the moving trolley 34 (via bolts). By setting the rotating arm 37 and inclining both the clamping cylinder 38 and the rotating arm 37 towards each other, the clamping force of the gripper 372 is improved. In the initial state, the piston rod of the cylinder 38 is in the retracted state, and the gripper mechanism 35 is open. The piston rod of cylinder 38 extends and pushes the rotating arm 37, which in turn causes the gripper rod 371 to drive the gripper 372 to rotate, so that the two gripper mechanisms 35 clamp the material tank rack.

[0054] See Figure 7 The Y-axis lifting mechanism 20 includes a lifting motor 221, two lifting frames 22, two drive shafts 222, and two screws 223. The output shaft of the lifting motor 221 is equipped with input conical teeth. One end of each of the two drive shafts 222 is equipped with output conical teeth, which are located symmetrically on both sides of the input conical teeth and mesh with them. The other ends of the two drive shafts 222 are connected to the corresponding screws 223 via a transmission structure. The bottom of each lifting frame 22 is screwed onto the corresponding screw 223. In operation, the lifting motor 221 drives the drive shafts 222 to rotate accordingly by rotating forward or backward. The drive shafts 222 transmit torque to the screws 223, causing them to rotate synchronously forward or backward. The rotation of the screws 223 changes the distance between the two bottoms of the lifting frame 22 connected to it, thereby lowering or raising the lifting frame 22.

[0055] See Figure 7The Y-axis lifting mechanism 20 also includes a support base 26, which is fixedly connected to the top of the lifting frame 22. A through hole is provided in the middle of the support base 26, through which the material tank support 12 passes. Several bottom support cylinders 261 and swing cylinders 264 are provided on the support base 26. A support block 262 is provided at the free end of the piston rod of the bottom support cylinder 261, and a swing rod 263 is provided at the free end of the piston rod of the swing cylinder 264. In the working state, the support block 262 supports the bottom of the crossbeam of the material tank support 12, and the free end of the swing rod 263 abuts against the outside of the material tank 11. By fixing the support base 26 to the top of the lifting frame 22, it is easy to lift the support base 26 by the lifting frame 22. Several bottom support cylinders 261 and swing cylinders 264 are also provided on the support base 26. A support block 262 is provided at the free end of the piston rod of the bottom support cylinder 261, and a swing rod 263 is provided at the free end of the piston rod of the swing cylinder 264. When it is necessary to place the material tank 11 on the support base 26, the support block 262 lifts it to the bottom of the crossbeam of the material tank support 12, so that the material tank support 12 is kept at the set height. The free end of the swing rod 263 abuts against the outside of the material tank 11 to position the material tank 11 and prevent the material tank 11 from shifting on the material tank support 12.

[0056] See Figure 7 Specifically, several bottom support cylinders 261 and swing cylinders 264 are provided and evenly distributed around the circular shape of the material tank support 12. The swing rod 263 is hinged to a bracket at the output end of the swing cylinder 264, and the piston rod of the swing cylinder 264 is connected to the end of the swing rod 263 that is hinged to the bracket. This facilitates the swing rod 263 to swing radially along the material tank 11 via the swing cylinder 264 during operation. A support block 262 is hinged to a bracket at the output end of the bottom support cylinder 261, and the piston rod of the bottom support cylinder 261 is connected to the end of the support block 262 that is hinged to the bracket. This facilitates the bracket providing support to the support block 262 during operation.

[0057] See Figures 7-9 The Y-axis lifting mechanism 20 also includes a valve stem 24, a valve motor 241, and a valve stem locking structure. The ball valve end of the valve stem 24 is connected to the inner cavity of the discharge pipe section of the material tank 11. The output shaft of the valve motor 241 is connected to the valve stem 24. The valve stem locking structure is slidably connected to the rod portion of the valve stem 24. The valve motor 241 drives the valve stem 24 to rotate, thereby automatically opening and closing the discharge port of the material tank 11.

[0058] See Figures 7-12 The valve stem locking structure includes a locking block 247, a valve bracket 242, a base plate 248, and a motor cylinder 2452. The valve bracket 242 is radially slidably connected to the base plate 248 (specifically, the base plate 248 is provided with a bracket guide rail 245, and the bottom of the valve bracket 242 is provided with a slider that can be slidably connected to the bracket guide rail 245). The valve motor 241 is fixedly connected to the bottom of the adapter bracket. The adapter bracket is generally rectangular plate structure. The adapter bracket is slidably connected to the top inner side of the valve bracket 242. The motor cylinder 2452 is fixedly connected to the valve bracket 242. The free end of the piston rod of the motor cylinder 2452 is connected to the adapter bracket. The locking block 247 is connected to the output shaft of the valve motor 241. The locking block 247 is slidably connected to the rod portion of the valve stem 24. To facilitate operation, when the valve bracket 242 slides to the end near the valve stem 24, the valve motor 241 mounted on the valve bracket 242 moves synchronously. This causes the locking block 247 mounted on the output shaft of the valve motor 241 to radially abut against the valve stem 24, restricting the radial movement of the valve stem 24. Then, the motor cylinder 2452 drives the adapter bracket to slide, causing the valve motor 241 connected to the adapter bracket to move synchronously. The movement of the valve motor 241 causes the locking block 247 to move along the length of the valve stem 24, thus abutting against the free end of the valve stem 24, restricting the movement of the valve stem 24 along its length, and keeping the ball valve in its set position. Specifically, the free end of the valve stem 24 is provided with a protrusion. When the valve motor 241 moves, it causes the locking block 247 to move along the length of the valve stem 24, causing the locking block 247 to abut against the protrusion on the valve stem 24, restricting the movement of the valve stem 24 along its length.

[0059] See Figure 11 and Figure 12 Specifically, the valve stem locking structure further includes a mounting block 39, a base plate 248, and a push plate 2481. A locking block 247 is slidably connected to the mounting block 39, and springs 246 are provided on both sides of the locking block 247. The mounting block 39 is connected to the output shaft of the valve motor 241. The push plate 2481 is fixedly connected to one end of the base plate 248. The piston rod of the valve cylinder 243 is connected to the push plate 2481. The valve cylinder 243 is fixedly connected to the valve bracket 242. A motor guide rail 2451 is provided on the inner top of the valve bracket 242. A slider is provided on the adapter bracket 391, and the slider slides in cooperation with the motor guide rail 2451.

[0060] See Figures 9-10The Y-axis lifting mechanism 20 also includes two docking blocks 253 and two docking cylinders 254. The molding machine 23 is provided with a molding machine feed pipe 251. The free ends of the piston rods of the two docking cylinders 254 are respectively connected to the outside of the corresponding docking blocks 253. The inner side of each docking block 253 is provided with an arc-shaped groove. In the working state, the top of the molding machine feed pipe 251 and the bottom of the discharge pipe section of the conveying tank 11 form a mating part. The arc-shaped groove abuts against the outer periphery of the mating part. By setting two docking cylinders 254 and connecting the free ends of the piston rods of the two docking cylinders 254 to the outside of the corresponding docking blocks 253, and by setting an arc-shaped groove on the inner side of the docking block 253 to fit with the outer periphery of the part where the top of the molding machine feed pipe 251 matches the bottom of the discharge pipe section of the conveying tank 11, the top of the molding machine feed pipe 251 is docked with the bottom of the discharge pipe section of the conveying tank 11, so that the powder in the conveying tank 11 can smoothly enter the molding machine and prevent powder leakage.

[0061] See Figures 9-10 The inner sides of the two mating blocks 253 are provided with grooves 2531. The outer periphery of the top of the molding machine feed pipe 251 and the outer periphery of the bottom of the feed tank 11 discharge pipe section are provided with protrusions 252. The protrusions 252 constitute the mating parts. In the working state, the two protrusions 252 are engaged in the grooves 2531. By providing a groove 2531 on the inner side of the docking block 253, and providing protrusions 252 on the outer periphery of the top of the molding machine feed pipe 251 and the outer periphery of the bottom of the discharge pipe section of the conveying tank 11, it is easy to engage the two protrusions 252 in the groove 2531, further limiting the top of the molding machine feed pipe 251 and the bottom of the discharge pipe section of the conveying tank 11, further improving the docking accuracy between the top of the molding machine feed pipe 251 and the bottom of the discharge pipe section of the conveying tank 11, thereby preventing the leakage of flammable NdFeB powder and ensuring the safety of the production site.
