[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

A mounting seat 12 is fixedly connected to the inner side of the main frame 1 near one end, and a bracket 20 is fixedly installed on the inner side of the main frame 1 near the other end. A material sweeping mechanism 32 is arranged on the surface of the bracket 20, and a third belt 33 is arranged at the upper end of the bracket 20. A dust blocking mechanism 41 is arranged on the surface of the third belt 33.

[0030] A fifth roller 34 is sleeved and connected to the surface of the third belt 33. An axial flow fan blade 35 is fixedly connected to the bottom surface of the fifth roller 34. An air guiding groove is arranged at one end of the axial flow fan blade 35. A housing 38 is sleeved and connected to the outside of the axial flow fan blade 35. A bottom plate 39 is fixedly connected to the bottom surface of the housing 38. A slot is arranged at the middle part of the surface of the bottom plate 39. The dust blocking mechanism 41 includes a mounting frame 411. The mounting frame 411 is fixedly connected to the bottom plate 39. A driving roller 412 is rotatably connected to the inner side of the mounting frame 411. A wedge block is fixedly connected to one end of the driving roller 412. Driven rollers 413 are symmetrically rotatably connected to the surface of the bottom plate 39 on one side of the mounting frame 411. A cloth sleeve 414 is sleeved and connected to the surfaces of the driving roller 412 and the driven rollers 413.

[0031] A punching machine 2 is fixedly installed on the top surface of the main frame 1. First cylinders 3 are symmetrically fixedly installed on both sides of the punching machine 2 on the top surface of the main frame 1. A bearing plate 4 is fixedly connected to the output end of the first cylinder 3.

[0032] A second cylinder 5 is fixedly installed at the edge near one end of the top surface of the bearing plate 4. A feeder 6 is fixedly connected to the output end of the second cylinder 5. Feeding pipes 7 are symmetrically fixedly installed on the top surface of the feeder 6. Slide seats 8 are fixedly installed on both sides of the feeder 6. A slide rail 9 is sleeved and connected to the surface of the slide seat 8. The slide rail 9 is fixedly connected to the bearing plate 4. A die base 10 is fixedly connected to the middle part of the surface of the bearing plate 4. An abutting rod 11 is fixedly installed on the surface of the main frame 1 below the die base 10.

[0033] One end surface of the mounting base 12 is fixedly connected with a blanking rack 13. The top surface of the mounting base 12 is fixedly installed with a first motor 14. The top surface of the blanking rack 13 is fixedly installed with an isolation bin 15. A connecting rack 16 is rotatably connected inside the isolation bin 15. A grinding rack 17 is fixedly connected to the side surface of the connecting rack 16. The output end of the first motor 14 is fixedly connected with the connecting rack 16. One end surface of the isolation bin 15 is fixedly connected with a cover plate 18. A feed hopper 19 is welded and fixed to the surface of the cover plate 18. The bottom surface of the blanking rack 13 is fixedly connected with a transfer pipe, and the transfer pipe is sleeved and connected with the feed pipe 7. During the powder metallurgy pressing operation, the user first needs to connect the feed hopper 19 with the external equipment for storing metal powder. During the feeding process, the pre-treated metal powder will enter the inside of the isolation bin 15.

[0034] Among them, a convex ring extends outward at the edge of the grinding rack 17. The convex ring is rotatably arranged on the inner surface of the isolation bin, and a number of through grooves are formed through the grinding rack 17. And there is a gap between the grinding rack 17 and the inner surface of the isolation bin 15, which is used for grinding the metal powder passing through the through grooves. The outer surface of the grinding rack 17 is provided with concave-convex patterns.

[0035] When the first motor 14 is pre-started, the connecting rack 16 will drive the grinding rack 17 to rotate. During this period, the connecting rack 16 will throw the metal powder between the isolation bin 15 and the grinding rack 17. Through the patterns, additional grinding care will be carried out on the metal powder poured into the gap between the two, so as to ensure the fine grinding and full mixing of the powder. Then open the valve body on the surface of the transfer pipe, and the metal powder can enter the inside of the feeder 6 through the feed pipe 7. Then control the second cylinder 5 to operate, and the blanking part of the feeder 6 can be made to contact the die base 10. After waiting for the metal powder to be poured in place, then control the second cylinder 5 to retract, and the stamping machine 2 can be driven to perform stamping operations. After the powder is pressed into shape, the output end of the first cylinder 3 can be controlled to extend. Then the formed object will be exposed from the die base 10 under the support of the plate structure at the top of the abutting rod 11. Then while performing the next feeding operation, the feeder 6 will push the formed object forward to complete blanking at the same time.

[0036] For this explanation, the feeder 6 in this application adopts the feeding structure commonly used in powder metallurgy pressing equipment, for example, it is composed of a feed pipe and a leakage trough at the bottom, and realizes the material blocking function by closely adhering to the bottom plate structure during the process, so as to perform blanking at the upper end of the mold. This technology is the prior art and is common knowledge in the field of those skilled in the art, so it will not be elaborated here.

[0037] A second motor 21 is fixedly installed on the top surface of the support 20. The output end of the second motor 21 is fixedly connected to a first belt roller 22. A first belt 23 is sleeved and connected to the surface of the first belt roller 22. A vertical frame 24 is fixedly installed on the surface of the support 20 near the middle. A connecting shaft 25 is sleeved and connected to the surface of the vertical frame 24. Transmission gears 26 are fixedly connected to the two ends of the connecting shaft 25. A sleeve shaft is fixedly connected to the surface of the main frame 1 above the transmission gears 26. A first driven gear 27 is rotatably connected to the surface of the sleeve shaft. A second belt roller 28 is fixedly connected to the surface of the first driven gear 27. A second driven gear 29 is rotatably connected to the surface of the support 20 below the transmission gears 26. A third belt roller 30 is fixedly connected to the surface of the second driven gear 29. A second belt 31 is sleeved and connected to the surface of the third belt roller 30. The transmission gears 26, the first driven gear 27 and the second driven gear 29 are meshed and connected. One end of the connecting shaft 25 is connected to a pulley, and the pulley is connected to the first belt 23 for transmission;

[0038] The material sweeping mechanism 32 includes a connecting plate 321 which is fixedly connected to the support 20. Connecting seats 322 are symmetrically and fixedly installed on the surface of the connecting plate 321 near the middle. A third air cylinder 323 is rotatably connected to the surface of the connecting seat 322. The output end of the third air cylinder 323 is rotatably connected to a support arm 324 which is rotatably connected to the support 20. A hollow shaft 326 is rotatably connected to the surface of the support arm 324 near one end edge. A fourth belt roller 325 is fixedly connected to the surface of the hollow shaft 326 near one end. A brush 327 is fixedly connected to the surface of the hollow shaft 326 near the other end. A guiding strip 328 is fixedly connected to the surface of the brush 327. Convex teeth 329 are symmetrically and fixedly connected to one end surface of the hollow shaft 326. The fourth belt roller 325 is sleeved and connected to the second belt 31.

[0039] For this explanation, the support arm 324 is a telescopic structure, which is composed of two plug plates with opposite ends inserted into each other, and a shock absorber is arranged between the two plug plates. The hollow shaft 326 is arranged at the end of the plug plate on the side of the support arm 324 away from the support 20, and the output end of the third air cylinder 323 is also connected to this plug plate, so that during the rotation of the support arm 324, the normal transmission of the second belt 31 can be ensured.

[0040] Regarding the metal powder scattered on the surface of the bearing plate 4 after powder metallurgy pressing operations, in order to reduce waste of raw materials and the workload of manual cleaning, the user can start the second motor 21. During its operation, through the transmission of the first belt roller 22 and the first belt 23, and the linkage with the coupling shaft 25 and the transmission gear 26, it will ultimately drive the second driven gear 29 and the third belt roller 30 to rotate. Subsequently, it will drive the second belt 31 to drive the fourth belt roller 325 to rotate, and finally control its rotation on the surface of the support arm 324. The bristles 327 at its bottom will clean the residual metal powder, while the guiding strip 328 at the bottom will cause the metal powder to gather in the middle during the cleaning process to prevent the metal powder from scattering everywhere;

[0041] A cover shell 36 is provided on the outside of the axial flow fan blade 35. Suspension brackets 37 are symmetrically and fixedly connected to the top surface of the cover shell 36. An enclosing shell 38 is fixedly connected to the bottom surface of the cover shell 36. Storage hoppers 40 are symmetrically welded and fixed to the surface of the bottom plate 39. For the metal powder floating in the air, in order to absorb it, the user can use the third belt 33 sleeved on the second belt roller 28. After transmission, the fifth belt roller 34 will drive the axial flow fan blade 35 to rotate, so that a suction force is generated at the bottom of the axial flow fan blade 35, and the structure of the enclosing shell 38 guides it to the slot. Most of the particulate dust will stay in the storage hopper 40 under the blockage of the cloth sleeve 414, while a small number of small-volume powder particles will directly adhere to the surface of the cloth sleeve 414. The user can directly open the storage hopper 40 to take out the collected metal dust particles later. For the cleaning of the sweeping mechanism 32 and the dust blocking mechanism 41, the user can control and handle them separately. After the third cylinder 323 operates, the hollow shaft 326 will perform a circular motion around the support arm 324 and the connecting plate 321. During this process, the hollow shaft 326 moves along with the support arm 324, and at the same time, shock absorption connection treatment is carried out using shock absorbers, which can not only ensure the dust collection effect but also prevent the second belt 31 from disengaging from the fourth belt roller 325. After controlling the hollow shaft 326 to move to the lower end of the axial flow fan blade 35, that is, when the upper end of the hollow shaft 326 is in contact and communication with the lower end of the axial flow fan blade 35, after normally driving the axial flow fan blade 35, when its blades rotate, an air pressure difference is generated using the airfoil section, and then the air is pushed to continuously flow from the air inlet end to the air outlet end. The overall air flow direction is parallel to the axis. Due to the hollow structure of the hollow shaft 326 with open ends at both ends and the upper end being close to the axial flow fan blade 35, during the process, the metal dust inside the guiding strip 328 will be absorbed upward and then collected inside the storage hopper 40 like the floating metal dust. For the metal dust adhering to the surface of the cloth sleeve 414, the user can further control the operation of the third cylinder 323. As it drives the support arm 324 to rotate, finally control the hollow shaft 326 to move to directly below the mounting bracket 411, and then control the second motor 21 to drive. Finally, the convex teeth 329 at the top of the hollow shaft 326 are butted against the wedge block, and then the second motor 21 is reopened, and then the hollow shaft 326 can drive the driving roller 412 to rotate.

[0042] For this description, a valve is provided at the bottom opening of the storage hopper 40. When cleaning the dust, the valve is opened, and after the dust cleaning is completed, the valve is closed, so that the adsorbed dust and the dust cleaned from the cloth sleeve 414 can be centrally collected for treatment; both the convex teeth 329 and the wedge block are convex in shape, and the preparation material is a magnetic material. At the same time, the hollow shaft 326 and the driving roller 412, which are respectively connected, are in a rotatable state. Before the hollow shaft 326 moves below the driving roller 412, after controlling the operation of the second motor, through the transmission of each accessory, as the distance between the two is reduced, under the influence of magnetism, the wedge block will rotate in cooperation with the driving roller 412 to a certain extent. Finally, the convex teeth 329 and the wedge block will be inserted in alignment. During the operation, the driving roller 412 also plays a role in rotating and driving to tighten the cloth sleeve 414, so that the cloth sleeve 414 can also rotate synchronously on the surface of the driven roller 413. A scraper is provided at the position on the surface of the mounting frame 411 close to the cloth sleeve 414, which can carefully scrape the powder on the surface of the cloth sleeve 414 and fall into the storage hopper 40, waiting for subsequent centralized cleaning.

[0043] Working principle of the present invention: During the powder metallurgy pressing operation, the user first needs to connect the feed hopper 19 to an external device for storing metal powder. During the feeding process, the pre-treated metal powder will enter the interior of the isolation chamber 15. When the first motor 14 is pre-started, the connecting frame 16 will drive the grinding frame 17 to rotate, thereby performing additional grinding care on the poured metal powder to ensure fine grinding and sufficient mixing of the powder. Then, by opening the valve body on the surface of the rotary connection pipe, the metal powder can enter the interior of the feeder 6 through the feed pipe 7. After that, by controlling the operation of the second cylinder 5, the feeding part of the feeder 6 can be brought into contact with the die base 10. After waiting for the metal powder to be filled in place, by controlling the second cylinder 5 to retract, the stamping machine 2 can be driven to perform stamping operations. After the powder is pressed into shape, the user can control the output end of the first cylinder 3 to extend. Then, the formed object will be exposed from the die base 10 under the support of the abutting rod 11. Then, while performing the next feeding operation, the feeder 6 will push the formed object forward to complete feeding at the same time. Regarding the metal powder scattered on the surface of the bearing plate 4 after the powder metallurgy pressing operation, in order to reduce waste of raw materials and the workload of manual cleaning, the user can start the second motor 21. During its operation, through the transmission of the first roller 22 and the first belt 23, and the linkage with the coupling shaft 25 and the transmission gear 26, it will ultimately drive the second driven gear 29 and the third roller 30 to rotate. Subsequently, it will drive the second belt 31 to drive the fourth roller 325 to rotate, and finally control it to rotate on the surface of the support arm 324. The brush bristles 327 at its bottom will clean the remaining metal powder, while the guiding strip 328 at the bottom will cause the metal powder to gather in the middle during the cleaning process to prevent the metal powder from scattering everywhere. Regarding the metal powder floating in the air, after the user uses the third belt 33 to drive the second roller 28, the fifth roller 34 will drive the axial flow fan blade 35 to rotate, thereby generating suction at the bottom of the axial flow fan blade 35 and guiding it towards the slotted opening through the structure of the enclosure 38. Most of the particulate dust will stay in the storage hopper 40 under the blockage of the cloth sleeve 414, while a small number of small-volume powder particles will directly adhere to the surface of the cloth sleeve 414. The user can directly open the storage hopper 40 to take out the collected metal dust particles later. For the cleaning of the sweeping mechanism 32 and the dust-blocking mechanism 41, the user can control and handle them separately. By operating the third cylinder 323, after controlling the hollow shaft 326 to move to the lower end of the axial flow fan blade 35, normally driving the axial flow fan blade 35 will cause the metal dust inside the guiding strip 328 to be absorbed, and then, like the floating metal dust, it will be collected inside the storage hopper 40. For the metal dust adhering to the surface of the cloth sleeve 414, the user can further control the operation of the third cylinder 323 to make the convex teeth 329 at the top of the hollow shaft 326 dock with the wedge block, and then restart the second motor 21. After that, the hollow shaft 326 can drive the driving roller 412 to rotate, cooperating with the scraper that fits the surface of the cloth sleeve 414,Scrape the metal dust on the cloth cover 414 into the storage hopper 40, so as to ensure that the surface of the cloth cover 414 can be comprehensively cleaned.

[0044] The above has described an embodiment of the present invention in detail, but the content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application shall still fall within the patent coverage scope of the present invention.
