Description

Technical Field

[0001] This invention relates to the field of supporting equipment for fully automatic dry powder presses, specifically a multi-link feeding mechanism for a fully automatic dry powder press. Background Technology

[0002] Fully automatic dry powder presses are core equipment used in powder metallurgy, building materials, electronic components and other fields to press dry powder raw materials into shapes. With advantages such as high degree of automation, high production efficiency and good molding accuracy, they are widely used in the large-scale production of various dry powder products. As a key component of fully automatic dry powder presses, the feeding mechanism directly determines the uniformity of dry powder filling, feeding efficiency and the quality of the subsequent pressed finished products. Its performance is closely related to the overall operational stability and production qualification rate of the fully automatic dry powder press.

[0003] Currently, the feeding mechanism of fully automatic dry powder presses has many shortcomings in practical applications: quantitative control is difficult to achieve during feeding, and dry powder is prone to clumping and bridging due to stickiness or electrostatic force, leading to feeding blockage and unevenness, resulting in dry powder waste and unqualified pressed blanks; during the feeding process, the transmission structure has poor stability and insufficient feeding accuracy, which easily leads to problems such as material box misalignment and dry powder flying and stratification, affecting feeding efficiency and subsequent filling uniformity; in addition, there are no effective dust prevention measures during dry powder feeding and pre-extrusion, resulting in serious dust waste and environmental pollution. At the same time, the lack of a targeted pre-extrusion structure easily leads to loose and cracked pressed blanks, which cannot meet the continuous, clean, and high-precision production requirements of fully automatic dry powder presses. There is an urgent need for a feeding mechanism that can solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-link feeding mechanism for a fully automatic dry powder press to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A multi-link feeding mechanism for a fully automatic dry powder press includes: The base has a feeding groove on its top surface, a feeding rack is fixedly installed on the top surface of the base, and a storage box is provided on the top surface of the feeding groove. A feeding assembly, which is disposed inside the feeding rack, is used for feeding materials; A feeding assembly, disposed inside the base, is used to push the storage box.

[0006] Preferably, the feeding assembly includes: The feed inlet is located on the top surface of the unloading rack, and a feed pipe is fixedly installed inside the feed inlet. The material discharge port is located on the inner bottom surface of the material discharge frame, and a material discharge valve is fixedly installed inside the material discharge port.

[0007] Preferably, the feeding assembly further includes: Two vibration grooves are formed inside one side of the unloading frame, and a vibration motor is fixedly installed inside the vibration groove.

[0008] Preferably, the feeding assembly includes: Two mounting blocks are fixedly installed inside one side of the feeding trough. A rotating block is rotatably connected inside the mounting block, and a first connecting rod is rotatably connected to one side of the rotating block. The second link is rotatably connected to one side of the first link, and the second link connects the two rotating blocks together; A pusher plate, which is rotatably connected to one side of the first connecting rod; Two limiting blocks are fixedly installed on the inner top surface of the feeding trough. A third connecting rod is rotatably connected to one side of each limiting block, and the other end of the third connecting rod is rotatably connected to one end of the first connecting rod.

[0009] Preferably, the feeding assembly further includes: A drive slot is formed on one side of the base, and a servo motor is fixedly installed inside the drive slot. One end of the drive shaft of the servo motor is connected to one end of the rotating block.

[0010] Preferably, a mounting bracket is fixedly installed on the top surface of the base, and a cylinder is fixedly installed on the top surface of the mounting bracket. One end of the cylinder's telescopic shaft is connected to a pressing block.

[0011] Preferably, a dust collection box is fixedly installed on one side of the base, a dust suction groove is opened on one side of the inside of the feeding groove, a side plate is fixedly installed inside the dust suction groove, a plurality of suction heads are fixedly installed on one side of the side plate, and an air extraction pipe is connected between the dust collection box and the dust suction groove.

[0012] Preferably, an air pump is fixedly installed on the top surface of the dust collection box, a dust cover is movably installed on one end of the air pump extending to the dust collection box, and a box door is movably installed on one side of the dust collection box.

[0013] Preferably, the top surface of the base has two mounting slots, and an iron plate is fixedly installed inside the mounting slots. The bottom surface of the storage box has two fixing slots, and a magnet is fixedly installed inside the fixing slots.

[0014] Preferably, a controller is fixedly installed on one side of the base.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a feed inlet, the dry powder raw material enters the feed pipe through the feed inlet. The feed pipe guides the dry powder into the feeding rack. The controller controls the opening and closing of the feeding valve to achieve quantitative feeding of the dry powder, allowing the dry powder to fall accurately into the storage box on the feeding trough below through the feeding port. At the same time, the vibration motor is fixedly installed inside the vibration trough. When the vibration motor is started, it generates micro-amplitude vibration, which is transmitted to the entire feeding rack. This effectively prevents the dry powder from clumping or bridging due to stickiness or static electricity in the feed pipe, feeding port, and inside the feeding rack, ensuring smooth feeding of the dry powder. It achieves precise quantitative feeding of the dry powder, avoiding excessive or insufficient feeding that would lead to unqualified pressed blanks. The vibration structure solves the problems of dry powder blockage and clumping during feeding, improves the continuity and stability of feeding, and is simple in structure and easy to control, reducing dry powder waste during feeding. It is suitable for the continuous production needs of fully automatic dry powder presses.

[0016] 2. By setting a servo motor, which is fixedly installed inside the drive slot, it serves as the power source for the feeding assembly. The controller controls the servo motor to start, and the drive shaft of the servo motor drives the rotating block to rotate around the mounting block. The limit block is fixed on the top surface of the feeding slot, and the third link is hinged between the limit block and the first link, limiting and guiding the movement trajectory of the first link. This allows the first link to drive the pusher plate to make a smooth linear reciprocating motion along the feeding slot, thereby pushing the storage box to move within the feeding slot and completing the feeding action. The multi-link linkage structure, combined with the precise control of the servo motor, achieves smooth and accurate pushing of the storage box. The feeding stroke is controllable, with small errors, ensuring the uniformity of subsequent dry powder filling. The multi-link structure has high transmission efficiency and no rigid impact, reducing vibration during the feeding process and preventing dry powder from flying or separating in the storage box. The limit structure prevents the first link from deviating from its movement trajectory, improving feeding stability. At the same time, the linkage structure is reasonably designed, reliable in operation, and adaptable to the high-efficiency requirements of fully automatic feeding.

[0017] 3. By setting up an extrusion block, the mounting frame provides fixed support for the cylinder. When the storage box is pushed to the designated position, the controller controls the cylinder to start. The cylinder's telescopic shaft drives the extrusion block to move downward, pre-extruding the dry powder in the storage box to make the dry powder initially dense, preparing it for subsequent pressing. The pre-extrusion structure (cylinder, extrusion block) can reduce the gaps between dry powder particles, avoiding defects such as looseness and cracking in the blank during subsequent pressing, thus improving the pressing quality. The dust removal component can effectively collect the dry powder flying during the feeding process, avoiding waste of dry powder and preventing dust pollution of equipment and working environment, protecting the health of operators. The design of the dust cover and movable box door facilitates dust recovery and equipment maintenance. The overall structure is adapted to the clean and standardized production requirements of dry powder pressing. Attached Figure Description

[0020] Please see Figures 1 to 8In this embodiment of the invention, a multi-link feeding mechanism for a fully automatic dry powder press includes: a base 1, a feeding groove 2 on the top surface of the base 1, a feeding frame 3 fixedly installed on the top surface of the base 1, and a storage box 4 on the top surface of the feeding groove 2; a feeding assembly, which is located inside the feeding frame 3 and is used for feeding; a feeding component, which is located inside the base 1 and is used for pushing the storage box 4. The feeding assembly includes: a feeding port 5, which is located on the top surface of the feeding frame 3 and has a feeding pipe 6 fixedly installed inside the feeding port 5; a feeding outlet 7, which is located on the bottom surface inside the feeding frame 3 and has a feeding valve 8 fixedly installed inside the feeding outlet 7; the feeding assembly also includes: two vibration grooves 9, which are located on one side inside the feeding frame 3 and have a vibration motor 10 fixedly installed inside the vibration grooves 9. By setting the feed inlet 5, the dry powder raw material enters the feed pipe 6 through the feed inlet 5. The feed pipe 6 guides the dry powder into the feeding rack 3. The controller 35 controls the opening and closing of the feeding valve 8 to achieve quantitative feeding of the dry powder, so that the dry powder falls accurately into the storage box 4 on the feeding trough 2 below through the feeding port 7. At the same time, the vibration motor 10 is fixedly installed inside the vibration trough 9. When the vibration motor 10 is started, it generates micro-amplitude vibration, which is transmitted to the entire feeding rack 3. This can effectively prevent the dry powder from clumping or bridging due to stickiness or electrostatic force in the feed pipe 6, feeding port 7 and feeding rack 3, ensuring smooth feeding of the dry powder. It achieves precise quantitative feeding of the dry powder and avoids excessive or insufficient feeding, which would lead to unqualified pressed blanks. The setting of the vibration structure solves the problems of dry powder blockage and clumping, improves the continuity and stability of feeding, and is simple in structure and easy to control, reducing the waste of dry powder during the feeding process, and is suitable for the continuous production needs of fully automatic dry powder presses.

[0021] exist Figures 1-4 The feeding assembly includes: two mounting blocks 11, which are fixedly installed on one side of the inside of the feeding trough 2. A rotating block 12 is rotatably connected inside the mounting block 11, and a first connecting rod 13 is rotatably connected to one side of the rotating block 12; a second connecting rod 14, which is rotatably connected to one side of the first connecting rod 13, and the second connecting rod 14 connects the two rotating blocks 12 together; a pusher plate 15, which is rotatably connected to one side of the first connecting rod 13; and two limiting blocks 16, which are fixedly installed on the top surface inside the feeding trough 2. A third connecting rod 17 is rotatably connected to one side of the limiting block 16, and the other end of the third connecting rod 17 is rotatably connected to one end of the first connecting rod 13. The feeding assembly also includes: a drive groove 18, which is opened on one side of the base 1. A servo motor 19 is fixedly installed inside the drive groove 18, and one end of the drive shaft of the servo motor 19 is connected to one end of the rotating block 12. By setting a servo motor 19, which is fixedly installed inside the drive slot 18, as the power source for the feeding assembly, the controller 35 controls the servo motor 19 to start. The drive shaft of the servo motor 19 drives the rotating block 12 to rotate around the mounting block 11. When the rotating block 12 rotates, it drives the first connecting rod 13, which is hinged to it, to move. The second connecting rod 14 connects the two first connecting rods 13 into a whole, ensuring that the two rotating blocks 12 rotate synchronously and realizing the smooth linkage of the first connecting rods 13. At the same time, the limiting block 16 is fixed on the top surface of the feeding slot 2, and the third connecting rod 17 is hinged between the limiting block 16 and the first connecting rod 13, limiting and guiding the movement trajectory of the first connecting rod 13. The first connecting rod 13 drives the pusher plate 15 to make a smooth linear reciprocating motion along the feeding trough 2, thereby pushing the storage box 4 to move within the feeding trough 2 and completing the feeding action. The multi-link linkage structure, combined with the precise control of the servo motor 19, enables the smooth and precise pushing of the storage box 4. The feeding stroke is controllable with small errors, ensuring the uniformity of subsequent dry powder filling. The multi-link structure has high transmission efficiency and no rigid impact, reducing vibration during the feeding process and preventing dry powder from flying or separating in the storage box 4. The setting of the limit structure prevents the first connecting rod 13 from deviating from its movement trajectory, improving the feeding stability. At the same time, the linkage structure is reasonably designed, reliable in operation, and adaptable to the high-efficiency requirements of fully automatic feeding.

[0022] exist Figures 6-8 In the middle: A mounting bracket 20 is fixedly installed on the top surface of the base 1, and a cylinder 21 is fixedly installed on the top surface of the mounting bracket 20. One end of the telescopic shaft of the cylinder 21 is connected to a pressing block 22. A dust collection box 23 is fixedly installed on one side of the base 1. A dust suction trough 24 is opened on one side of the inside of the feeding trough 2. A side plate 25 is fixedly installed inside the dust suction trough 24. Multiple suction heads 26 are fixedly installed on one side of the side plate 25. An air extraction pipe 27 is connected between the dust collection box 23 and the dust suction trough 24. An air pump 28 is fixedly installed on the top surface of the dust collection box 23. A dust cover 29 is movably installed on one end of the air pump 28 extending to the dust collection box 23. A box door 30 is movably installed on one side of the dust collection box 23. By setting the extrusion block 22, the mounting frame 20 provides fixed support for the cylinder 21. When the storage box 4 is pushed to the designated position, the controller 35 controls the cylinder 21 to start. The telescopic shaft of the cylinder 21 drives the extrusion block 22 to move downward, pre-extruding the dry powder in the storage box 4 to make the dry powder initially compacted, preparing it for subsequent pressing. At the same time, the air pump 28 starts to generate negative pressure. The negative pressure is transmitted to multiple suction heads 26 in the dust collection tank 24 through the suction pipe 27. The suction heads 26 suck up the dry powder flying during the feeding process and the scattered dry powder on the edge of the storage box 4, and transport it to the dust collection box 23 for collection through the suction pipe 27. The dust cover 29 can prevent dust from entering the storage box. The dry powder collected in the dust collection box 23 is extracted by the air pump 28. The dry powder in the dust collection box 23 can be cleaned and recycled by periodically opening the box door 30. The pre-extrusion structure (cylinder 21, extrusion block 22) can reduce the gap between dry powder particles, avoid defects such as looseness and cracking of the blank during subsequent pressing, and improve the pressing quality. The dust collection component can effectively collect the dry powder flying during the feeding process, which not only avoids the waste of dry powder, but also prevents dust from polluting the equipment and working environment, and protects the health of operators. The design of the dust cover 29 and the movable box door 30 facilitates dust recovery and equipment maintenance. The overall structure is adapted to the clean and standardized production requirements of dry powder pressing.

[0023] exist Figures 1-3 In the middle: the top surface of the base 1 has two mounting slots 31, and an iron plate 32 is fixedly installed inside the mounting slots 31. The bottom surface of the storage box 4 has two fixing slots 33, and a magnet block 34 is fixedly installed inside the fixing slots 33. A controller 35 is fixedly installed on one side of the base 1. By setting an iron plate 32, which is fixedly installed inside the mounting groove 31, and installing a magnet 34 in the fixing groove 33 on the bottom of the storage box 4, when the storage box 4 is placed on the feeding groove 2, the magnet 34 and the iron plate 32 attract each other, realizing the rapid positioning and fixing of the storage box 4 on the feeding groove 2, and preventing the storage box 4 from shifting or shaking during the feeding process; the controller 35 is fixed on one side of the base 1 and is electrically connected to all electrical components such as the servo motor 19, the vibration motor 10, the feeding valve 8, the cylinder 21, and the air pump 28, and can centrally control the start of each component. The system includes stop and operation parameter adjustments to achieve automated linkage operation of the entire feeding mechanism; the magnetic adsorption fixing structure is simple in structure and easy to operate, enabling quick positioning and disassembly of the storage box 4, improving the efficiency of equipment debugging and maintenance, and effectively avoiding problems such as dry powder spillage and uneven filling caused by the displacement of the storage box 4 during feeding; the controller 35 realizes the automated control of the mechanism, reduces manual intervention, improves production efficiency, and facilitates flexible adjustment of operating parameters according to different specifications of dry powder and product requirements, enhancing the versatility and adaptability of the mechanism.

[0024] The working principle of this invention is as follows: First, the storage box 4 is placed on the feeding groove 2. The magnet block 34 in the fixing groove 33 on the bottom of the storage box 4 and the iron plate 32 in the mounting groove 31 of the base 1 attract each other, so as to realize the quick positioning and fixation of the storage box 4 and prevent the displacement and shaking during the subsequent feeding process. Subsequently, the device is activated, and the controller 35 controls the feeding assembly to start working. The dry powder raw material enters the feeding pipe 6 through the feeding port 5. The feeding pipe 6 guides the dry powder into the feeding rack 3. The controller 35 controls the opening and closing of the feeding valve 8 according to preset parameters to achieve quantitative feeding of the dry powder, so that the dry powder falls accurately into the storage box 4 below through the feeding port 7. At the same time, the controller 35 controls the vibration motor 10 in the vibration groove 9 to start, generating micro-amplitude vibration and transmitting it to the entire feeding rack 3, effectively preventing the dry powder from clumping or bridging in the feeding pipe 6, the feeding port 7 and the feeding rack 3, ensuring smooth and uniform feeding. After feeding is completed, the controller 35 controls the feeding assembly to start, and the servo motor 19 in the drive groove 18 starts running. Its drive shaft drives the rotating block 12 to rotate around the mounting block 11. When the rotating block 12 rotates, it drives the first connecting rod that is hinged to it. When rod 13 moves, the second connecting rod 14 connects the two first connecting rods 13 into a whole, ensuring that the two rotating blocks 12 rotate synchronously and realize the smooth linkage of the first connecting rods 13. At the same time, the third connecting rod 17 hinged on the limit block 16 limits and guides the movement trajectory of the first connecting rod 13, so that the first connecting rod 13 drives the pusher plate 15 to make a smooth linear reciprocating motion along the feeding groove 2, thereby pushing the storage box 4 to move towards the pre-extrusion and subsequent pressing station to complete the feeding action. When the storage box 4 is pushed to the designated station, the controller 35 controls the cylinder 21 on the mounting frame 20 to start. The telescopic shaft of the cylinder 21 drives the extrusion block 22 to move downward, pre-extruding the dry powder in the storage box 4, making the dry powder initially dense, preparing for the formal pressing process of the subsequent fully automatic dry powder press, and avoiding defects such as looseness and cracking of the blank during formal pressing. Throughout the feeding and pre-extrusion process, the controller 35 synchronously controls the dust removal components. The air pump 28 starts to generate negative pressure, which is transmitted through the extraction pipe 27 to multiple suction heads 26 in the dust collection tank 24. The suction heads 26 suck up the dry powder flying during the feeding process and the dry powder scattered from the edge of the storage box 4, and transport it to the dust collection box 23 for collection through the extraction pipe 27. The dust cover 29 prevents the dry powder collected in the dust collection box 23 from being extracted by the air pump 28. The operator can periodically open the box door 30 to clean the dry powder in the dust collection box 23. Cleaning and recycling prevents waste of dry powder and dust pollution. After a feeding operation is completed, the controller 35 controls the reset of each component: the cylinder 21 drives the extrusion block 22 to rise and reset, the servo motor 19 drives the multi-link mechanism and the pusher plate 15 to reset, the vibration motor 10 and the air pump 28 stop running, and the discharge valve 8 is closed. Then the storage box 4 can be replaced or the next round of feeding operation can be carried out to achieve continuous and automated feeding. The whole process does not require much manual intervention and is suitable for the high-efficiency production needs of fully automatic dry powder presses.
