Description

Technical Field

[0001] This utility model belongs to the field of powder separation technology, specifically, it relates to a metal powder separation device for casting grinding equipment. Background Technology

[0002] The invention includes: a dispensing box, inside which a dispensing mechanism is installed, and the dispensing mechanism is equipped with a buffer assembly; a loading mechanism is installed at the bottom of the dispensing box; the buffer assembly includes a second servo motor fixed to the inner wall of the dispensing box, the output end of the second servo motor being fixedly connected to a rotating shaft, and blades being fixedly sleeved on the outer ring of the rotating shaft; the dispensing mechanism includes a partition plate fixed to the inner wall of the dispensing box, and the rotating shaft is rotatably connected to the partition plate. This invention uses the dispensing mechanism to evenly divide metal powder mixed with plastic granules into several portions, which are then lowered into the corresponding loading mechanisms via the buffer assembly. The buffer assembly effectively mitigates the impact of the metal powder mixed with plastic granules on the dispensing box, preventing it from breaking.

[0003] Utility model patent CN217805348U discloses a metal powder mixed with plastic granules packaging device, comprising: a packaging box, an internal dispensing mechanism, a buffer assembly, and a loading mechanism at the bottom of the packaging box; the buffer assembly includes a second servo motor fixed to the inner wall of the packaging box, the output end of the second servo motor being fixedly connected to a rotating shaft, and blades fixedly sleeved on the outer ring of the rotating shaft; the dispensing mechanism includes a partition plate fixed to the inner wall of the packaging box, and the rotating shaft is rotatably connected to the partition plate. The dispensing mechanism can evenly divide the metal powder mixed with plastic granules into several portions, which are then lowered into the corresponding loading mechanisms via the buffer assembly. The buffer assembly effectively mitigates the impact of the metal powder mixed with plastic granules on the packaging box, preventing it from breaking.

[0004] However, the existing dispensing process relies on an intermittent mode of "single storage - single dispensing - shutdown for barrel replacement," which cannot achieve continuous operation and significantly restricts overall production efficiency. Looking at the process details, the device uses the cooperation of interceptor plate two and the feeding hole to first guide the material into a fixed-capacity storage chamber, and then the material is fed into the dispensing barrel through a blade buffer. When the pressure sensor detects that the dispensing barrel is full, the operation of servo motor two must be stopped to interrupt the feeding. Then, the clamp on the suspension plate is manually opened, the full dispensing barrel is removed, an empty dispensing barrel is placed in, and it is re-secured by the clamp. Finally, servo motor two is restarted to resume dispensing. The entire barrel replacement process requires a complete interruption of the dispensing operation, which not only generates a large amount of ineffective downtime, but also involves many manual operations, which can easily extend the downtime cycle due to differences in operating speed. In high-volume, high-frequency packaging scenarios, this intermittent process leads to a significant decrease in equipment utilization. The accumulated downtime significantly reduces the total packaging volume per unit time, making it difficult to meet the core efficiency requirements of continuous industrial production. This is especially true when processing large quantities of mixtures of metal powder and plastic granules, where the capacity loss due to process interruptions is even more pronounced. In view of this, this utility model is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A metal powder separation device for casting grinding equipment, comprising: A placement seat is used to carry the separation box and transport the separation box via a turntable, providing a moving path for receiving metal powder; The discharge component is disposed on one side of the support of the placement seat and is used to drive the separation box to move out of the placement slot of the placement seat after the separation box receives the powder. The separator is connected to an external support via a mounting plate. It is used to store the metal powder to be separated and to quantitatively feed the powder into the separator via a discharge pipe controlled by a solenoid valve.

[0006] Preferably, the placement seat includes a bracket, a mounting frame, a stepper motor, a turntable, a placement slot, a separation box, and a box slot; The bracket is a frame structure and serves as the main load-bearing component for the placement seat; The mounting bracket is located at the lower center of the bracket and is fixedly connected to the bracket via a fixing rod, used to support and fix the stepper motor; The stepper motor is fixed on the mounting bracket, with its output shaft facing upward and fixedly connected to the center of the turntable. It is used to drive the turntable to rotate around its own axis to realize the conveying of the separation box. The turntable is a circular plate, horizontally positioned above the support, with multiple placement slots spaced apart along the circumferential direction on the edge of the turntable; The placement slot is a groove adapted to the separation box and is used to place the separation box. The separation box moves with the turntable to the bottom of the separation component to receive the powder. The slot is located at the top of the bracket and has an arc-shaped structure. The arc-shaped trajectory is adapted to the rotation trajectory of the turntable and is used to guide the separation box to slide into the placement slot of the turntable. The separation box is an open-top box placed in a slot to receive metal powder fed into the separator's discharge pipe.

[0007] Preferably, the discharge component includes a fixed plate, a movable frame, a cylinder, a baffle plate, and a guide rod; Two fixing plates are provided, symmetrically fixed in the slot in the middle of one side of the bracket, and the fixing plates are provided with movable pins; The movable frame is a movable clamp structure, which is hinged to the fixed plate by a movable pin. The movable frame can be rotated around the movable pin, and the free end of the movable frame is detachably connected to the upper surface of the bracket by magnetic attraction, so as to fix or unfold the movable frame. The cylinder is fixed to the top of the movable frame, and the movable end of the cylinder faces the turntable and is fixedly connected to the baffle plate, which is used to drive the baffle plate to move in the direction of approaching / moving away from the turntable. The movable frame has a through slot, and the guide rod passes through the through slot. One end of the guide rod is fixedly connected to the baffle plate, and the other end extends out of the through slot to limit the movement trajectory of the baffle plate and ensure that the baffle plate moves in a straight line. The baffle plate is a plate body adapted to the side wall of the separation box. When the separation box moves with the turntable to the position corresponding to the discharge part, the cylinder drives the baffle plate to move towards the separation box. The baffle plate abuts against the side wall of the separation box, thereby driving the separation box to move out of the placement slot of the turntable.

[0008] Preferably, the separating component includes a mounting plate, a discharge hopper, a discharge pipe, and a solenoid valve; The mounting plate is a rectangular plate that is fixed to an external support and serves as the load-bearing foundation for the separable component. The feeding hopper is fixed to the upper surface of the mounting plate and is a funnel-shaped structure with an open top, used to store metal powder to be separated generated during the grinding of castings. The discharge pipe is a cylindrical pipe, fixed at the bottom center of the discharge hopper, and connected to the inside of the discharge hopper, used to convey the metal powder in the discharge hopper downward to the separation box; The solenoid valve is fixed to the bottom end of the discharge pipe, and the outlet of the solenoid valve corresponds to the separation box on the placement seat.

[0009] Preferably, the stepper motor is a precision speed-controlled stepper motor, the inner wall of the slot is provided with a smooth coating, the separation box is made of wear-resistant metal material, and the side wall of the box is provided with anti-slip protrusions.

[0010] Preferably, the magnetic connection between the movable frame and the upper surface of the support is achieved using a strong magnetic block, with the magnetic force being greater than the total weight of the movable frame, cylinder, and baffle plate. A lubricating sleeve is provided at the interface between the guide rod and the through groove of the movable frame to reduce frictional resistance during the movement of the guide rod. An elastic buffer layer is provided on the side of the baffle plate near the separation box. The cylinder is an adjustable stroke cylinder, which can flexibly adjust the moving distance of the baffle plate according to the distance between the turntable and the support.

[0011] Compared with the prior art, the present invention has the following advantages: This invention, through a coordinated design of rotary conveying, synchronous receiving, and automatic removal, completely breaks the intermittent operation mode of existing devices, realizing a continuous process for metal powder separation and significantly improving operational efficiency. Structurally, the rotary table in the placement base has multiple placement slots spaced along its edge. A stepper motor precisely controls the rotation speed and stopping position of the rotary table. When one separation box moves with the rotary table to receive powder under the separation component, another empty separation box automatically slides into the adjacent placement slot through an arc-shaped slot to complete the feeding preparation. When the receiving separation box continues to rotate with the rotary table to the discharge component position, the air... The cylinder drives the baffle plate to move linearly along the guide rod, contacting the side wall of the separation box and removing it from the placement slot. Throughout the process, the turntable operates continuously without stopping to wait for box replacement. This design forms a cyclical process of separation box feeding - powder quantitative dispensing - automatic removal of the separation box, with each link seamlessly connected. It not only eliminates the downtime caused by manual box replacement in existing devices, but also increases the processing capacity per unit time by operating multiple placement slots in parallel. In the scenario of batch separation of metal powder after casting grinding, this continuous system can significantly improve equipment utilization, reduce ineffective time loss, and meet the efficiency requirements of large-scale industrial processing.

[0012] This invention, by employing a combination of precise material control via solenoid valves and automated operation, not only solves the problem of insufficient quantitative accuracy in existing devices but also significantly improves the automation level and material adaptability of the equipment. In terms of quantitative control, the separator controls the opening and closing of the discharge pipe via a solenoid valve. The opening and closing time of the solenoid valve can be flexibly adjusted through an external control system, eliminating the need for a fixed-volume storage chamber. Regardless of variations in the particle size and density of the metal powder, the single-dispensing amount can be precisely controlled by adjusting the opening and closing time of the solenoid valve, avoiding quantitative deviations caused by changes in material density in existing devices. Simultaneously, the solenoid valve's response... The device offers high speed and can adjust the discharge in real time based on the material receiving status of the separation box, ensuring consistency in the amount dispensed each time and meeting the stringent requirements for quantitative accuracy of metal powder. In terms of automation, the entire process, from feeding and receiving the material to removing it from the separation box, requires no manual intervention. It can run automatically simply by setting parameters through the control system, reducing errors caused by manual operation and lowering the labor intensity of operators. In addition, the device's structural design is highly compatible with material characteristics. Whether it is fine-particle metal powder or polished powder with slight impurities, stable separation can be achieved by adjusting the solenoid valve parameters and the speed of the turntable.

The stepper motor 13 is fixed on the mounting frame 12, with its output shaft facing upward and fixedly connected to the center of the turntable 14, used to drive the turntable 14 to rotate around its own axis. The separation box 16 is conveyed by a turntable 14, which is a circular plate horizontally positioned above the support 11. Multiple placement slots 15 are spaced apart along the circumferential direction on the edge of the turntable 14. The placement slots 15 are grooves adapted to the separation box 16 and are used to place the separation box 16. The separation box 16 rotates and moves with the turntable 14 to the bottom of the separation component 3 to receive the powder. The box groove 17 is opened on the top of the support 11 and has an arc-shaped structure. The arc-shaped trajectory is adapted to the rotation trajectory of the turntable 14 and is used to guide the separation box 16 to slide into the placement slot 15 of the turntable 14. The separation box 16 is a box with an open top and is placed in the placement slot 15 to receive the metal powder fed by the discharge pipe 33 of the separation component 3.

[0020] More specifically, the stepper motor 13 is a precision speed-controlled stepper motor, which can adjust the rotation speed and stopping position of the turntable 14 through an external control system to ensure that the separation box 16 can accurately stop directly below the solenoid valve 34 to receive the material, and can move to the corresponding position of the discharge part 2 after receiving the material; the inner wall of the box groove 17 is provided with a smooth coating (such as a polytetrafluoroethylene coating) to reduce the frictional resistance when the separation box 16 slides into the placement groove 15 and avoid the separation box 16 getting stuck; the separation box 16 is made of wear-resistant metal material, and the side wall of the box body is provided with anti-slip protrusions to enhance the contact friction between the baffle plate 24 and the separation box 16, ensuring that the baffle plate 24 can stably drive the separation box 16 to move out.

The movable frame 22 can be rotated around the movable pin, and the free end of the movable frame 22 is detachably connected to the upper surface of the support 11 by magnetic attraction, so as to realize the fixing or unfolding of the movable frame 22; the cylinder 23 is fixed to the top of the movable frame 22, and the cylinder 24 is fixed to the top of the movable frame 22. The movable end of the 3 faces the turntable 14 and is fixedly connected to the baffle plate 24, which is used to drive the baffle plate 24 to move in the direction of approaching / away from the turntable 14; the movable frame 22 has a through groove, and the guide rod 25 passes through the through groove. One end of the guide rod 25 is fixedly connected to the baffle plate 24, and the other end extends to the outside of the through groove, which is used to limit the movement trajectory of the baffle plate 24 and ensure that the baffle plate 24 moves in a straight line; the baffle plate 24 is a plate body adapted to the side wall of the separation box 16. When the separation box 16 moves with the turntable 14 to the position corresponding to the discharge part 2, the cylinder 23 drives the baffle plate 24 to move towards the separation box 16. The baffle plate 24 abuts against the side wall of the separation box 16, thereby driving the separation box 16 to move out of the placement groove 15 of the turntable 14.

[0022] More specifically, the magnetic connection between the movable frame 22 and the upper surface of the support 11 uses a strong magnetic block, and the magnetic force is greater than the total weight of the movable frame 22, cylinder 23, and baffle plate 24, ensuring the fixed stability of the movable frame 22 when it is not in operation; a lubricating sleeve is provided at the joint between the guide rod 25 and the through groove of the movable frame 22 to reduce the frictional resistance when the guide rod 25 moves, ensuring the smooth movement of the baffle plate 24; an elastic buffer layer (such as a rubber layer) is provided on the side of the baffle plate 24 near the separation box 16 to prevent damage to the side wall of the separation box 16 when the baffle plate 24 touches the separation box 16; the cylinder 23 is an adjustable stroke cylinder, which can flexibly adjust the moving distance of the baffle plate 24 according to the distance between the turntable 14 and the support 11, ensuring that it can stably drive the separation boxes 16 of different sizes to move out of the placement slot 15.

[0023] Specifically, the separator 3 is connected to an external support via a mounting plate 31.

The separator 3 includes a mounting plate 31, a hopper 32, a discharge pipe 33, and a solenoid valve 34. The mounting plate 31 is a rectangular plate, fixed to the external support, serving as the foundation for the separator 3. The hopper 32 is fixed to the upper surface of the mounting plate 31 and is a funnel-shaped structure with an open top, used to store the metal powder to be separated generated during casting grinding. The discharge pipe 33 is a cylindrical pipe. Fixed at the bottom center of the discharge hopper 32 and communicating with the inside of the discharge hopper 32, it is used to convey the metal powder in the discharge hopper 32 downward to the separation box 16; the solenoid valve 34 is fixed at the bottom end of the discharge pipe 33, and the outlet of the solenoid valve 34 corresponds to the separation box 16 on the placement seat 1.
