Description

Technical Field

[0001] This utility model relates to the field of feeding mechanism technology, and in particular to a quantitative powder filling press. Background Technology

[0002] In many booming industrial sectors such as powder metallurgy, pharmaceuticals, chemicals, and ceramics, powder filling presses are key core equipment, playing a crucial role. Their core function lies in their ability to precisely and efficiently fill powdered materials into a mold according to predetermined requirements, and then, through specific pressing processes, ultimately produce products that meet specific shape and size standards, satisfying the needs of different industrial production stages.

[0003] Currently, most mainstream powder filling presses on the market suffer from a significant drawback: they can only execute a single, fixed quantitative powder quantity standard, lacking the ability to flexibly adjust the powder quantity according to actual production needs. However, in actual industrial production scenarios, the situation is often complex and varied. Different types of products have different powder quantity requirements due to their varying uses and performance requirements; even for the same product, the powder quantity requirements may differ significantly at different production stages, such as the R&D trial production stage, the small-batch production stage, and the large-scale mass production stage.

[0004] However, existing powder-filling presses are limited by their design, making the operation extremely cumbersome and complex when adjusting powder quantity. For example, specific powder feeding components may need to be replaced to meet the new powder quantity requirements. These components are often precision-structured and have strict installation requirements, making the replacement process not only time-consuming but also requiring specialized technicians. Furthermore, the metering device must be recalibrated after component replacement to ensure powder quantity accuracy. This series of operations significantly extends equipment downtime, severely impacting production line continuity and ultimately reducing overall production efficiency.

[0005] Therefore, this application develops a quantitative powder filling press to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a quantitative powder filling press to solve the problem of the inability to adjust the powder feeding amount in the prior art.

[0007] The technical solution of this utility model is: a quantitative powder filling press, comprising: a powder filling box, a quantitative component, and a powder feeding component arranged sequentially along the powder moving direction;

[0008] The powder filling box is used to hold powder, and has a first through hole at the bottom so that the powder can flow out through the first through hole;

[0009] The metering component includes a metering column, a driving device, and a powder quantity control unit. The powder quantity control unit has a second through hole inside. One end of the metering column is mounted on a cylinder, and the other end extends into the second through hole. By moving the metering column, the distance between the top surface of the metering column and the top surface of the powder quantity control unit is controlled, thereby controlling the powder volume. The driving device controls the powder quantity control unit to move along a first direction, so that the first through hole and the second through hole are connected or misaligned.

[0010] The powder feeding component reciprocates along a second direction at an angle to the first direction via a cylinder, receiving powder that has passed through the powder filling box and the metering component, and moving it into the mold.

[0011] Preferably, the powder quantity control unit includes a powder quantity control plate and a transition plate arranged sequentially along the powder movement direction. The second through hole includes a metering hole opened on the powder quantity control plate and a transition hole opened on the transition plate. Initially, the first through hole and the metering hole are misaligned, and one end of the metering column passes through the transition hole and is located inside the metering hole.

[0012] Preferably, the first through hole, the metering hole, and the transition hole are all arranged in an array, and when the first through hole and the metering hole are misaligned, when the first through hole and the metering hole are projected onto the transition hole, their projections correspond one-to-one with the transition hole.

[0013] Preferably, the driving device includes a first driving part and a second driving part disposed in the first direction and located on both sides of the powder filling box. The driving end of the first driving part is located on the powder filling box and drives the powder filling box to move along the first direction. The driving end of the second driving part is located on the powder quantity control plate and drives the powder filling box and the powder quantity control plate to move together in opposite directions along the first direction.

[0014] Preferably, the powder feeding assembly includes a powder feeding hopper and a control unit. The powder feeding hopper is disposed along the second direction and away from the powder filling box, and a powder feeding cavity corresponding to the metering orifice is opened on the powder feeding hopper. The control unit is located on the powder feeding hopper, positions the powder feeding cavity, and controls the powder feeding cavity to correspond with the cavity of the mold so that the powder flows into the mold.

[0015] Preferably, the control unit includes a mounting groove, a limiting plate, an elastic element, and a limiting block. The mounting groove is opened inside the powder feeding hopper and close to the powder filling box. The limiting plate is slidably disposed on the bottom surface of the powder feeding hopper and has a limiting hole corresponding to the powder feeding cavity. The limiting block is located inside the mounting groove and is fixedly connected to one end of the limiting plate, forming a protruding structure towards the mold. One end of the elastic element is connected to the limiting block, and the other end is connected to the side wall of the mounting groove. When the limiting block abuts against the mold, the limiting hole communicates with the cavity of the mold, the elastic element is compressed, and the powder feeding hopper slides relative to the limiting plate, so that the powder feeding cavity and the limiting hole communicate.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] (1) The combination of the metering column and the powder control unit accurately controls the distance between the top surface of the metering column and the top surface of the powder control unit, thereby accurately controlling the capacity of the powder in the metering orifice, realizing accurate control of the powder capacity, and meeting the powder feeding requirements of different products;

[0018] (2) The powder feeding hopper in the powder feeding assembly has a powder feeding cavity that corresponds to the metering hole one by one, so that the powder material transmitted from the metering hole can fall accurately into the corresponding powder feeding cavity. Furthermore, when the powder feeding hopper moves, the limiting block first abuts against the mold, and the powder feeding hopper slides relative to the limiting plate to make the powder feeding cavity connect with the limiting hole, so as to achieve precise positioning of the powder feeding cavity and the mold cavity. Moreover, the elastic restoring force of the spring can reset the limiting block and the limiting plate, so as to prepare for the next powder feeding. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to specific embodiments:

[0026] like Figures 1-4 As shown, a quantitative powder filling press includes a powder filling box 1, a quantitative component 2, and a powder feeding component 3 arranged sequentially along the powder moving direction.

[0027] The main function of the powder filling box 1 is to contain the powder to be processed. A first through hole 11 is provided at the bottom of the box, through which the powder can flow out of the powder filling box 1, providing a source of powder for the subsequent quantitative and powder feeding process.

[0028] The metering component 2 includes a metering column 21, a driving device 22, and a powder quantity control unit 23. The powder quantity control unit 23 has a second through hole 24 inside. One end of the metering column 21 is mounted on a cylinder, and the other end extends into the second through hole 24 of the powder quantity control unit 23. The cylinder drives the metering column 21 to move, which can accurately control the distance between the top surface of the metering column 21 and the top surface of the powder quantity control unit 23. This distance directly determines the capacity of the powder that can be contained in the second through hole 24, thereby realizing the control of the powder capacity. The driving device 22 can control the powder quantity control unit 23 to move along a first direction. When the powder quantity control unit 23 moves to a specific position, the first through hole 11 at the bottom of the powder filling box 1 is connected to the second through hole 24 inside the powder quantity control unit 23. At this time, the powder can flow from the first through hole 11 into the second through hole 24. When the powder quantity control unit 23 moves to other positions, the first through hole 11 and the second through hole 24 will be misaligned and separated, thereby preventing the powder from continuing to flow into the second through hole 24, thus completing the metering control of the powder.

[0029] The powder feeding assembly 3 includes a powder feeding hopper 31 and a control unit 32. The powder feeding hopper 31 is provided with a powder feeding chamber 311. The feeding assembly can reciprocate along a second direction perpendicular to the first direction through the action of the cylinder. During the reciprocating motion, the feeding hopper receives the powder after it has been processed by the powder filling box 1 and the metering component 2, and accurately moves the powder into the mold to complete the powder feeding process of the entire powder filling press.

[0030] In this embodiment, as Figures 2-3 As shown, the powder quantity control unit 23 includes a powder quantity control plate 231 and a transition plate 232 arranged sequentially along the powder movement direction. The second through hole 24 includes a metering hole 241 opened on the powder quantity control plate 231 and a transition hole 242 opened on the transition plate 232. The driving device 22 includes a first driving unit 221 and a second driving unit 222 located in the first direction and arranged on both sides of the powder filling box 1. The driving end of the first driving unit 221 acts on the powder filling box 1 and can drive the powder filling box 1 to move along the first direction. The driving end of the second driving unit 222 acts on the powder quantity control plate 231 and drives the powder filling box 1 and the powder quantity control plate 231 to move together in opposite directions along the first direction. In the initial state, the first through hole 11 at the bottom of the powder filling box 1 and the metering hole 241 on the powder quantity control plate 231 are misaligned and not connected. At the same time, one end of the metering column 21 passes through the transition hole 242 on the transition plate 232 and extends into the metering hole 241 of the powder quantity control plate 231.

[0031] Its working principle is as follows: When the powder feeding amount needs to be adjusted according to the requirements of different products, the operator will first adjust the height of the metering column 21. By changing the height of the metering column 21, the distance between the top surface of the metering column 21 and the top surface of the powder quantity control plate 231 can be precisely controlled, thereby adjusting the powder capacity that the metering hole 241 can hold, that is, the amount of powder fed. After adjusting the height of the metering column 21, the powder feeding process begins. First, the first drive unit 221 starts working, driving the powder filling box 1 to move along the first direction. As the powder filling box 1 moves, the first through hole 11 at its bottom gradually aligns with and connects with the metering hole 241 on the powder quantity control plate 231. At this time, the powder in the powder filling box 1 will flow into the metering hole 241 through the first through hole 11 until the metering hole 241 is filled with powder. Then, the first drive unit 221 drives the powder filling box 1 back to the initial position.

[0032] Subsequently, the metering column 21 descends until its top surface is level with the bottom surface of the powder quantity control plate 231. The second drive unit 222 is activated, driving the powder quantity control plate 231 and the powder filling box 1 to move in opposite directions along the first direction. During this movement, the originally misaligned metering hole 241 and the transition hole 242 gradually connect. At this time, the transition hole 242 corresponds to the powder feeding chamber 311 in the powder feeding assembly 3. The powder already filled in the metering hole 241 will be smoothly transferred to the powder feeding chamber 311 through the transition hole 242, preparing for the subsequent feeding of the powder into the mold.

[0033] Furthermore, the first through hole 11 at the bottom of the powder filling box 1, the metering hole 241 on the powder quantity control plate 231, and the transition hole 242 on the transition plate 232 are all arranged in an array. When the first through hole 11 and the metering hole 241 are projected onto the transition hole 242 from a direction perpendicular to the plane where the transition hole 242 is located, the projection of the first through hole 11 and the projection of the metering hole 241 correspond one-to-one with the transition hole 242. That is, the transition hole 242 needs to provide a moving channel for the metering column 21 and a moving channel for the powder to complete the metered powder feeding.

[0034] like Figure 4 As shown, the powder feeding hopper 31 is arranged along the second direction and away from the powder filling box 1. On the powder feeding hopper 31, there are powder feeding cavities 311 that correspond one-to-one with the metering holes 241. Each powder feeding cavity 311 corresponds to one metering hole 241, ensuring that the powder material transmitted from the metering hole 241 can accurately fall into the corresponding powder feeding cavity 311. In order to achieve the precise flow of powder material from the powder feeding cavity 311 into the mold cavity, a control unit 32 is provided on the powder feeding hopper 31 to position the powder feeding cavity 311, ensuring that when the powder feeding cavity 311 corresponds to the position of the mold cavity, the powder material can flow smoothly into the mold.

[0035] Specifically, the control unit 32 includes a mounting groove 321, a limiting plate 322, an elastic element 323, and a limiting block 324. The mounting groove 321 is located inside the powder feeding hopper 31 and near the powder filling box 1, providing mounting space for the limiting block 324. The limiting plate 322 is slidably disposed on the bottom surface of the powder feeding hopper 31, and has a limiting hole 325 corresponding to the powder feeding cavity 311. When the limiting hole 325 is aligned with the powder feeding cavity 311, the powder can flow out from the powder feeding cavity 311 through the limiting hole 325. The limiting block 324 is located in the mounting groove 321 and is fixedly connected to one end of the limiting plate 322, forming a structure protruding towards the mold. One end of the elastic element 323 is connected to the limiting block 324, and the other end is connected to the side wall of the mounting groove 321, providing elastic support and reset function for the limiting block 324 and the limiting plate 322. Specifically, the elastic element 323 is a spring.

[0036] In actual operation, when the powder feeding hopper 31 moves towards the mold, the limiting block 324 first comes into contact with the mold. As the powder feeding hopper 31 continues to move, the limiting block 324 is blocked by the mold and cannot move forward. The powder feeding hopper 31 then slides relative to the limiting plate 322. During this process, the spring is compressed, resulting in elastic deformation. At the same time, the originally misaligned powder feeding cavity 311 and the limiting hole 325 gradually connect. When the powder feeding cavity 311 and the limiting hole 325 are fully connected, the powder in the powder feeding cavity 311 can flow smoothly into the mold cavity through the limiting hole 325, completing a precise powder feeding operation. After the powder feeding is completed, the elastic restoring force of the spring will reset the limiting block 324 and the limiting plate 322, preparing for the next powder feeding.
