Description

Technical fields:

[0001] This invention relates to the field of powder pressing and molding equipment technology, and more specifically, to a powder press capable of cleaning residual powder. Background technology:

[0002] Powder forming presses are essential equipment in the machinery, pharmaceutical, chemical, food, and electronics industries for pressing granular raw materials into compacts under external loads. They enable the crucial process of powder pressing, transforming powder into dense, geometrically shaped parts. They are suitable for production units, laboratories, hospitals, and other departments producing powder-pressed products. However, powder residue often remains after each pressing cycle, hindering efficient reciprocating pressing and affecting the final product quality.

[0003] To remove powder residue, Chinese utility model patent application number CN201921761936.0 discloses a powder press that is easy to clean, including a base, a column, an upper pressure plate, a lower pressure plate, a motor, a pulley, and a threaded rod. A movable plate is installed on the threaded rod, and a brush is provided at the bottom of the movable plate. The brush contacts the lower pressure plate. The motor drives the pulley and the threaded rod to rotate, which in turn drives the movable plate and the brush to move. The cleaning of the lower pressure plate is completed by the linear sweeping motion of the brush.

[0004] Although the powder press is equipped with a dust cleaning device, it has been found in actual use that, due to the characteristics of the powder press, the residual dust tends to stick together and clump together. Therefore, direct cleaning with a straight brush cannot achieve a good cleaning result. Moreover, as time goes by, the powder clumping will become more and more serious, which will seriously affect the pressing quality of the product. Summary of the Invention:

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a powder press capable of cleaning residual powder, thereby solving the technical problems existing in the prior art. The powder press capable of cleaning residual powder can disperse bonded and lumpy powder, and then, in conjunction with brush cleaning, complete the residual powder cleaning work for the powder press.

[0006] The technical solution of the present invention is as follows:

[0007] A powder press capable of cleaning residual powder includes a lower pressing part disposed on a base, and an upper pressing part correspondingly disposed above the lower pressing part. The lower pressing part and the upper pressing part cooperate to form a powder pressing and forming structure. The base is provided with a cleaning device including a brush. When the lower pressing part and the upper pressing part are separated, the cleaning device can drive the brush to sweep along the pressing surface of the lower pressing part to clean the residual powder. The brush includes a cleaning brush and a vibrating brush. The vibrating brush is driven by a vertical vibration power device to vibrate up and down to disperse the residual powder clumps.

[0009] As a preferred embodiment, the vibrating brush is a soft brush, and when the vibrating brush vibrates up and down, at least some of the bristles will reciprocate to brush the pressing surface of the lower pressing part.

[0010] As a preferred embodiment, the brush of the vibrating part is provided with a pre-vibration part and a vibrating part. When cleaning the powder, the pre-vibration part acts on the pressing surface of the lower pressing part before the vibrating part. Both the pre-vibration part and the vibrating part are composed of columnar structures, and the hardness of the columnar body on the pre-vibration part is higher than the hardness of the columnar body on the vibrating part.

[0011] As a preferred embodiment, the end of the columnar body is a conical tip structure, with the tip of the conical tip facing the pressing surface of the lower pressing part.

[0012] As a preferred embodiment, the cleaning device includes a brush holder with the brush inside, and the brush holder includes dustproof side plates disposed on both sides of the brush cleaning path.

[0018] The present invention includes a cleaning brush and a vibrating brush; the cleaning brush can move with the cleaning device to clean the residual powder on the pressing surface of the lower pressing part; the vibrating brush can vibrate up and down to disperse the powder according to the characteristics of the pressed powder of the powder press, providing a good powder cleaning environment for the cleaning brush and improving the overall powder cleaning effect of the powder press.

[0019] The vibrating brush of this invention can be a hard brush or a soft brush, and may also include a pre-vibration section and a vibrating section to adapt to different types of powder cleaning, improve the cleaning adaptability of the powder press, and specifically improve the cleaning effect.

Detailed implementation method:

[0037] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. Furthermore, the terms "vertical," "horizontal," "top," "bottom," "front," "back," "upper," "lower," "inner," and "outer," etc., mentioned in the embodiments of the present invention, indicate orientation or positional relationships based on the appendix. Figure 1 The orientations or positional relationships shown, or the orientations or positional relationships in which the product is usually placed during use, are only for the purpose of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] The inventors discovered during actual operation of the powder press that a significant amount of powder remained on the press after each pressing cycle. If not cleaned, this powder easily accumulated, eventually forming a bump at the accumulation point, thus affecting the pressing quality of the product. The inventors researched and considered this technical problem, finding that manual cleaning with brushes was not only inefficient but also posed significant safety hazards. While linear mechanical brush cleaning, using a mechanical device to control the brush's linear movement to clean the powder press, could not achieve satisfactory cleaning results, because different powder products have different characteristics; some powder presses add binders during production, while others use molds. For powder presses that use binders, residual powder tends to clump together and form one or more powder clumps on the press plate. For powder presses using molds, the mold itself, including stressed and unstressed parts, exerts pressure on the residual powder between the mold and the press plate, causing it to form one or more powder clumps. Therefore, simply using a brush for linear cleaning is insufficient to effectively remove these powder clumps and clumps. To address these issues, the inventors initially planned to use a linear mechanical scraper cleaning method, controlling the linear movement of the scraper to clean the press plate of the powder press, aiming for better cleaning. However, during actual testing, it was found that the scraper setting required extremely high precision. If the height difference between the scraper and the press plate was too large, a good cleaning effect could not be achieved; if the height difference was too small, it could easily damage the scraper and the press plate. This was difficult to control in actual production and required an additional detection and control system or significant time investment to monitor and adjust the scraper position in real time, which was extremely inconvenient.

[0040] To address the above problems, the inventor sought a cleaning device that was more convenient to operate and more practical. Through research on the characteristics of residual powder in powder presses, the inventor discovered, as shown in the attached document... Figure 8 Since powder presses are generally produced by pressing from above and below, and powder has a certain degree of fluidity, the longitudinal particle spacing 'a' of the residual powder clumps is smaller than the transverse particle spacing 'b'. Therefore, if it is desired to disperse the powder in the clumps, it is preferable to separate the powder particles by increasing the transverse particle spacing 'b'. In view of this pressing characteristic, the inventors have proposed a powder press that can clean up residual powder. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] A powder press capable of cleaning residual powder, see attached document. Figure 1 To be continued Figure 7The system includes a lower pressing part 5 disposed on a base 1, and an upper pressing part 4 disposed above the lower pressing part 5. The lower pressing part 5 and the upper pressing part 4 cooperate to form a powder pressing and molding structure. The base 1 is provided with a cleaning device 6 including a brush 604. When the lower pressing part 5 is separated from the upper pressing part 4, the cleaning device 6 can drive the brush 604 to sweep along the pressing surface of the lower pressing part 5 to clean the residual powder. The brush 604 includes a cleaning brush 6041 and a vibrating brush 6042. The vibrating brush 6042 is driven by a vertical vibration power device to vibrate up and down to disperse the residual powder clumps. By vibrating the brush 6042 up and down, for powder blocks with a relatively large transverse particle spacing b, the transverse particle spacing b can be continuously increased by the up and down movement of the brush 6042, thus dispersing the powder blocks. For powder blocks with a relatively small transverse particle spacing b, continuous vibration impact or friction can also cause the powder particles in the powder block to show a tendency to separate under transverse force, gradually expanding the transverse particle spacing b, so as to achieve the purpose of dispersing the powder blocks.

[0042] As an embodiment of the present invention, please refer to the appendix. Figure 1 To be continued Figure 6 The system includes a base 1, with columns 102 at each of its four corners. A top plate 101 is located at the top of each column 102. An upper pressing part 4 is connected to the top plate 101 via an upper pressing part hydraulic cylinder 401. The upper pressing part hydraulic cylinder 401 controls the lifting and lowering of the upper pressing part 4. The structure and control of the upper pressing part hydraulic cylinder 401 are common knowledge in powder presses and will not be described in detail here. The base 1 has a lower pressing part receiving groove 105. A lower pressing part hydraulic cylinder 501 is connected to the bottom of the lower pressing part receiving groove 105, and a lower pressing part 5 is connected to the top of the lower pressing part hydraulic cylinder 501. By controlling the lifting and lowering of the lower pressing part hydraulic cylinder 501, the lower pressing part 5 can be controlled to lift and lower within the lower pressing part receiving groove 105. The structure and control of the lower pressing part hydraulic cylinder 501 are common knowledge in powder presses and will not be described in detail here.

[0043] Preferably, the lower pressing part receiving groove 105 is provided with sliding grooves 103 on both sides, and the lower pressing part 5 is provided with lower pressing part sliders 502 on both sides to accommodate the sliding grooves 103. The sliding grooves 103 and the lower pressing part sliders 502 constitute the limiting and guiding structure of the lower pressing part 5, ensuring the stable lifting and lowering of the lower pressing part 5. When the powder press is performing pressing work, the lower pressing part 5 descends into the lower pressing part receiving groove 105, so that the pressing plane of the lower pressing part 5 is lower than the worktable surface of the base 1, ensuring that the pressing work is carried out in a relatively sealed space, avoiding safety problems caused by accidental contact or pressing errors during the pressing process; at the same time, when the upper pressing part 4 and the lower pressing part 5 are closed during powder pressing, dust is easily diffused and raised outward due to the impact force. Powder pressing work is carried out in the lower pressing part receiving groove 105, which can, to a certain extent, avoid the problem of powder flying during pressing or demolding, and facilitates powder gathering and collection.

[0044] Preferably, the cleaning device 6 is connected to a drive device 3 that controls and drives the cleaning device 6 to move. The drive device 3 can be a motor push rod device, a hydraulic push rod device, or a mechanical transmission device, etc. In this embodiment, to ensure the stable movement of the cleaning device 6, the drive device 3 adopts a gear transmission structure, including two racks 308 mounted on the column 102. The racks 308 are provided with limiting grooves 309, and limiting blocks 305 are slidably connected in the limiting grooves 309. The limiting blocks 305 are set on the side plates 302, and the side plates 302 are connected to each other through the upper panel 301. A rotating shaft 306 is rotatably connected between the side plates 302. The rotating shaft 306 is connected to the output shaft end of the motor 303. The rotating shaft 306 is provided with two gears 307 that are adapted to be installed on the racks 308. The upper panel 301 is provided with a connecting plate 304 on the side facing the pressing part 5, and the cleaning device 6 is connected to the lower end of the connecting plate 304. By controlling the forward and reverse rotation of the motor 303, the rack 308 is driven to rotate accordingly, thereby moving the cleaning device 6 to complete the powder cleaning and resetting work.

[0045] Preferably, the cleaning device 6 includes a vibration device housing 601 and a brush housing 602. The brush housing 602 includes dustproof side plates 6021 disposed on both sides of the cleaning path of the brush 604. The brush housing 602 is provided with a mounting plate 603, which includes a cleaning mounting plate 6031 for connecting the cleaning brush 6041 and a vibration mounting plate 6032 for connecting the vibration brush 6042. In this embodiment, the cleaning part mounting plate 6031 is fixedly connected to the brush receiving part 602, and the cleaning part brush 6041 has a long-bristle structure. The bristle length of the cleaning part brush 6041 can be determined according to the specific structural dimensions between the pressing part 5 and the cleaning part mounting plate 6031. When the driving device 3 drives the cleaning device 6 to move, the cleaning part brush 6041 can always keep in contact with the pressing surface of the pressing part 5 and stably follow the pressing surface of the pressing part 5 to clean the powder, so as to achieve a better powder cleaning and agglomeration effect. Further preferably, in this embodiment, during the powder cleaning process, the dustproof side plate 6021 can prevent the powder from being lifted and scattered from both sides of the straight cleaning direction of the brush 604, and the mounting plate 603 can prevent the powder from being lifted and scattered from above, so as to achieve a better powder collection effect and avoid polluting the production environment.

[0046] Preferably, the vertical vibration power device is disposed in the vibration device housing 601. The vertical vibration power device can be a vertical vibration motor or a vertical vibration system formed by other mechanical structures, such as a cam or a deflector wheel. This embodiment provides a vertical vibration system mode formed by a mechanical structure, including a rotating wheel 605. The rotating wheel 605 is connected to a rotating motor, which drives the rotating wheel 605 to rotate. The rotating motor is placed in the vibration device housing 601. The connection between the rotating motor and the rotating wheel 605, and the control of the rotating motor are common knowledge and existing technologies, so they will not be described in detail here, nor are they shown in the accompanying drawings. The rotating wheel 605 has an arc-shaped notch 6051. A vibration part mounting plate 6032 is provided below the rotating wheel 605. The vibration part mounting plate 6032 has a push rod 606 that is adapted to move with the rotating wheel 605. A return spring 607 is installed between the vibration part mounting plate 6032 and the top surface of the vibration device housing 601. As a further preferred embodiment, in order to ensure that the vibration mounting plate 6032 can vibrate stably up and down, and to facilitate the replacement of the brush structure, the vibration mounting plate 6032 and the vibration device housing 601 can be designed with a detachable guide structure such as a sliding groove, a slider mounting structure, or a guide rod mounting structure. The detachable guide structure is a well-known prior art, and those skilled in the art can fully understand and reproduce it in conjunction with the content of this invention, so it will not be described in detail here, nor is it shown in the accompanying drawings.

[0047] As a further preferred embodiment, a dust collection section 608 is installed on the vibrating part mounting plate 6032 facing the pressing part 5. The dust collection section 608 is used to absorb the powder raised by the up-and-down vibration of the vibrating part brush 6042, thus preventing powder from contaminating the production environment. The dust collection section 608 can be a fine mesh structure design or an electrostatic adsorption structure design. Both the fine mesh structure and the electrostatic adsorption structure are common knowledge structures, so they will not be described in detail here, and are also shown in the attached drawings.

[0048] Preferably, when the raw material powder of the powder press has low viscosity and the pressed powder block has low hardness, the viscosity between the powder block particles is low, making them easy to disperse by impact. The vibrating brush 6042 is preferably a hard brush. Specifically, the hardness of the hard brush is relative to the hardness of the powder particles, that is, the hardness of the hard brush is greater than the hardness of the powder particles. This ensures that when the vibrating brush 6042 vibrates up and down under the drive of the vertical vibration power device, the bristles can effectively impact the powder block to widen the lateral powder particle spacing b and disperse the powder block. The hardness of the hard brush can be selected by those skilled in the art in combination with the content of this invention and the specific characteristics of the powder being produced, so it will not be described in detail here.

[0049] Further, as a preferred embodiment, an adjustable vibration gap is provided between the vibrating brush 6042 and the pressing part 5. The vibration gap refers to the initial distance between the vibrating brush 6042 and the pressing part 5, which facilitates the impact of the brush bristles on the powder compact. Specifically, when the vibrating brush 6042 vibrates downwards under the drive of the vertical vibration power device, it impacts the pressing surface of the pressing part 5. Each bristle continuously impacts the pressing surface of the pressing part 5 at a single point. During this impact, the bristles of the vibrating brush 6042 continuously penetrate the powder compact, widening the lateral particle spacing b of the powder compact, thus dispersing the particles within the powder compact. Furthermore, the adjustable vibration spacing means that the bristle length can be shortened to increase the overall hardness of the vibrating brush 6042. In this case, the distance between the vibrating brush 6042 and the pressing part 5 increases, requiring an increase in the vibration amplitude to improve the impact effect and the powder dispersion effect. The specific size of the bristle length and vibration amplitude depends on the actual device size. Those skilled in the art can set it themselves in conjunction with the content of this invention, so it will not be described in detail here.

[0050] Preferably, the base 1 is provided with a collection section receiving groove 104, in which a collection section 2 is installed. The top of the collection section receiving groove 104, near the pressing part 5, is provided with an inclined surface 1041. The inclined surface 1041 provides a flow guide for the swept powder, optimizing the powder collection effect. As the driving device 3 drives the cleaning device 6 to move, the brush 604 of the cleaning device 6 sweeps the powder on the pressing surface of the pressing part 5. When the driving device 3 drives the cleaning device 6 to move above the collection section 2, the brush 604 sweeps the powder along the inclined surface 1041 into the collection section 2, completing the powder collection work.

[0051] As a second embodiment of the present invention, based on the first embodiment, when the raw material powder of the powder press has a high viscosity and the pressed powder block has a low hardness, the powder particles are prone to sticking to the pressing surface of the lower pressing part 5. Therefore, the vibrating brush 6042 is preferably a soft brush. Specifically, the soft brush refers to a brush with a certain toughness and softness. When the vibrating brush 6042 presses the lower pressing part 5 downward, the bristles of the vibrating brush 6042 will naturally bend along the pressing surface of the lower pressing part 5. When the vibrating brush 6042 leaves the pressing surface of the lower pressing part 5, the bristles can automatically return to their original shape. It should be noted that the vibrating brush 6042 is not necessarily better the softer it is. When the vibrating brush 6042 vibrates up and down, the bristles continuously rub against the pressing surface of the lower pressing part 5 to disperse the powder clumps through friction or impact at the bristle tips. Therefore, if the brush is too soft, it is difficult to achieve an effective powder clump dispersion effect; if it is too hard, it is easy to cause the brush to break. Those skilled in the art can select a soft brush with appropriate toughness and softness based on the content of this invention and the hardness of the powder particles to be produced, so it will not be described in detail here.

[0052] Preferably, to ensure that at least some bristles of the vibrating brush 6042 reciprocate by brushing the pressing surface of the lower pressing part 5 when it vibrates up and down, the length of the bristles should be greater than the difference between the height difference between the vibrating mounting plate 6032 and the lower pressing part 5 and the difference in the amplitude of the bristles. When the vibrating brush 6042 vibrates up and down under the action of the vibrating device, due to the relatively long bristles, the vibrating brush 6042 will continuously rub against the pressing surface of the lower pressing part 5, and the bottom of the bristles will also continuously wash the powder clumps, dispersing the powder clumps that are stuck together, or allowing the powder to directly adhere to the vibrating brush 6042, thereby optimizing the cleaning effect.

[0053] As a third embodiment of the present invention, based on embodiment one, refer to the appendix. Figure 7When the raw material powder particles of the powder press are small and the pressed powder block is hard, it is difficult to achieve the optimal powder dispersion effect through the vibrating brush 6042. Therefore, a pre-vibration section 6043 and a vibration section 6044 are added at the vibrating brush 6042. During powder cleaning, the pre-vibration section 6043 acts on the pressing surface of the lower pressing section 5 before the vibration section 6044 and the vibrating brush 6042, and the height of the pre-vibration section 6043 is smaller than the height of the vibration section 6044. During the cleaning process, the pre-vibration section 6043 first cracks and disperses the powder block, and the vibration section 6044 then further vibrates and disperses the powder block that has cracked or has a tendency to crack, thereby improving the powder dispersion effect.

[0054] Preferably, considering the different functional characteristics of the pre-vibration section 6043 and the vibration section 6044, the hardness of the pre-vibration section 6043 should be higher than that of the vibration section 6044. The pre-vibration section 6043 is used to disperse and crack powder blocks with high hardness; therefore, it is preferably made of materials with high hardness, such as ferrous metals or high-hardness plastics. The vibration section 6044 is used to further impact and disperse powder blocks that have a tendency to disperse or have already cracked under the action of the pre-vibration section 6043; therefore, it is preferably made of elastic materials with a certain hardness, such as rubber, to form an elastic impact, dispersing the powder blocks while avoiding damage to the pressing surface of the lower pressing section 5. Further preferably, to avoid damaging the lower pressing section 5, the bottom of the pre-vibration section 604 should never contact the lower pressing section 5; specifically, the height of the pre-vibration section 604 is less than the difference between the height difference between the pre-vibration section 604 and the lower pressing section 5 and the difference in the amplitude of the pre-vibration section 604. When the pre-vibration part 6043 vibrates up and down, it will disperse the upper part of the powder block and crack and open the lower part of the powder block. At the same time, the vibration part 6044 will further impact the lower part of the powder block to achieve the effect of completely dispersing the powder block.

[0055] Preferably, referring to the brush structure, the pre-vibration section 6043 and the vibration section 6044 are preferably composed of multiple columnar structures. The smaller the cross-sectional diameter of the columnar structure, the better its point impact effect on the powder compaction block, and the easier it is to expand the lateral powder particle spacing b of the powder compaction block. However, it should be noted that the smaller the cross-sectional diameter of the columnar structure, the greater the difficulty in its processing and assembly. Those skilled in the art can select a columnar structure of appropriate size based on the content of this invention and the actual powder particle size and hardness in production, which will not be detailed here. Considering the characteristics of the powder compaction block remaining in the powder press, the ends of the columnar structures that make up the pre-vibration section 6043 and the vibration section 6044 are preferably conical structures. The tip of the conical structure faces the pressing section 5. By impacting the powder compaction block with the tip of the conical structure, a better impact effect can be generated, expanding the lateral powder particle spacing b of the powder compaction block and optimizing the powder dispersion effect.

[0056] The specific usage method is as follows:

[0057] First, select the appropriate brush type according to the powder type. During operation, after the powder press completes the powder pressing work, control the motor 303 of the drive device 3 to rotate, which in turn drives the gear 307 to rotate on the rack 308, moving the cleaning device 6. During the movement of the cleaning device 6, control the vertical vibration power device to drive the vibrating brush 6042 to vibrate up and down, dispersing powder clumps and powder pressure clumps. At the same time, during the movement, the cleaning brush 6041 will sweep the powder on the pressing surface of the lower pressing part 5 in the direction of movement. When the cleaning device 6 moves above the collecting part 2, the cleaning brush 6041 sweeps the powder into the collecting part 2, completing the cleaning. Control the motor 303 of the drive device 3 to reverse, the device resets, and prepares for cleaning again.
