Description

Technical Field

[0001] This utility model relates to the field of waste toner collection technology, and more specifically, to a waste toner collection device for 3D printers. Background Technology

[0002] Problems during the residual powder conveying process:

[0003] During the feeding process, residual powder tends to stick and accumulate on the inner wall of the device. This phenomenon not only affects the normal conveying of residual powder, but also leads to a series of derivative problems. The gradually accumulating sticky residual powder will reduce the channel area and reduce the conveying efficiency. The accumulated residual powder may suddenly fall off, causing uneven powder distribution in downstream equipment. Long-term sticky residual powder may also degrade in performance, affecting the quality of recycled material. In addition, the sticking phenomenon will increase the difficulty of equipment cleaning, prolong maintenance time, and increase operating costs.

[0004] Traditional filter assembly installation methods typically use bolt fixing or snap-fit ​​connections. These methods have obvious drawbacks. Bolted connections require frequent disassembly and assembly, which is cumbersome and time-consuming. Snap-fit ​​connections may have insufficient strength or wear out quickly. When it is necessary to clean or replace the filter assembly, the complicated disassembly and assembly process not only reduces work efficiency but may also damage parts due to improper operation. In addition, the inconvenient installation method also increases the difficulty of daily inspections, which can easily lead to untimely maintenance. Utility Model Content

[0030] Please see Figures 1-5A 3D printer waste toner collection device includes a feed box assembly 1, a filter box 2, a feed hammering mechanism, a filter mounting mechanism, and a snap-fit ​​auxiliary mechanism. The feed hammering mechanism includes a fixed frame 3, a connecting frame 4, a rotating frame 5, a hydraulic cylinder 6, and a hammering block 7. The fixed frame 3 is fixedly installed at both ends of the feed box assembly 1, the connecting frame 4 is installed at the bottom end of the fixed frame 3, one end of the rotating plate is rotatably connected to the connecting frame 4, both ends of the hydraulic cylinder 6 are rotatably connected to the connecting frame 4 and the rotating plate, and the hammering block 7 is installed at one end of the rotating plate, with one end of the hammering block 7 connected to the feed box assembly 1. The material bin assembly 1 has a surface contact setting. The filter installation mechanism includes a clamping tube 8, a clamping rod 9, a clamping groove 10, a stabilizing spring 11, a rocker arm 12, a directional ring 13, and a pressing groove 14. The clamping groove 10 is located on the side wall of the clamping rod 9. The rocker arm 12 is rotatably mounted on the side wall of the clamping tube 8. The stabilizing spring 11 is installed inside the clamping tube 8. The directional ring 13 is directionally slidably mounted on the outer wall of the clamping tube 8. The pressing groove 14 is located on the directional ring 13. The pressing groove 14 presses against the rocker arm 12, causing the other end of the rocker arm 12 to pry into the clamping groove 10, thereby pressing the clamping rod 9 against the stabilizing spring 11.

[0031] In this embodiment, the fixed frames 3 at both ends of the feed box assembly 1 support the rotating plate via connecting frames 4. The hydraulic cylinder 6 controls the reciprocating motion of the rotating plate. When the hydraulic cylinder 6 extends, it drives the rotating plate to rotate around the connecting frame 4, causing the hammering block 7 installed at the end of the rotating plate to contact the surface of the feed box assembly 1, thus achieving a hammering action. When the hydraulic cylinder 6 retracts, the rotating plate returns to its original position, and the hammering block 7 leaves the surface of the feed box. This periodic hammering action prevents residual powder from clumping or adhering in the feed box, ensuring that the residual powder falls smoothly into the filter box 2. The component 24 is connected to the clamping tube 8 on the mating plates 26 at both ends of the filter box 2 via the clamping rod 9 on the mounting plate 25. When the clamping rod 9 is inserted into the clamping tube 8, the clamping groove 10 on the side wall of the clamping rod 9 engages with the rocker plate 12 inside the clamping tube 8. When the directional ring 13 slides on the outer wall of the clamping tube 8, the pressing groove 14 on it presses against the rocker plate 12, causing the other end of the rocker plate 12 to rock into the clamping groove 10. At the same time, the clamping rod 9 presses the stabilizing spring 11 inside the clamping tube 8, forming a stable three-point support structure, which realizes the quick installation and reliable fixation of the filter assembly 24.

[0032] The snap-fit ​​auxiliary mechanism includes a rotating ramp 15, a top-loading ramp 16, a rotating ring 17, a pressing groove 18, a fixing block 19, and a spring block 20. The rotating ramp is rotatably mounted on the outer wall of the snap-fit ​​tube 8. The top-loading ramp 16 is mounted on the top end of the directional ring 13. The rotating ring 17 is mounted on the top of the rotating ramp ring. The fixing block 19 is mounted on the outer wall of the snap-fit ​​tube 8. The spring block 20 is mounted on the fixing block 19. The pressing groove 18 is set on the rotating ring 17. The spring block 20 extends into the pressing groove 18 step by step, so that the rotating ramp ring rotates stably and the top-loading ramp ring and the directional ring 13 move.

[0033] In this embodiment, the rotating ramp 15 on the outer wall of the snap-fit ​​tube 8 cooperates with the spring block 20 on the fixed block 19 through the rotating ring 17. The pressing groove 18 on the rotating ring 17 causes the spring block 20 to extend into the groove step by step, ensuring the stable rotation of the rotating ramp 15. When the rotating ramp 15 rotates, the directional ring 13 is moved by the top ramp 16, thereby achieving precise control of the pressure on the rocker plate 12. The reset spring 27 provides a reverse thrust between the directional ring 13 and the outer wall of the snap-fit ​​tube 8. The push block 28 acts on the rocker plate 12 to achieve snap-fit ​​and unlock, thereby achieving quick disassembly of the filter assembly 24.

[0034] Please see Figures 1-5 As a supplementary embodiment of a 3D printer residual powder collection device for the feeding hammer mechanism, filter installation mechanism, and snap-fit ​​auxiliary mechanism: A collection box is installed at the bottom of the filter box 2, and a box cover 21 is installed on the side of the collection box. A top cover 22 is installed at the top of the feeding box, and a feeding pipe 23 is passed through the top cover 22. One end of the feeding pipe 23 is connected to an external printer. A filter assembly 24 is slidably installed inside the filter box 2, and a mounting plate 25 is installed at one end of the filter assembly 24. Matching plates 26 are installed at both ends of the filter box 2, and a snap-fit ​​tube 8 is fixedly installed on the matching plate 26. One end of the snap-fit ​​rod 9 is connected to the mounting plate 25, and the other end of the snap-fit ​​rod 9 extends through the matching plate 26 to quickly snap-fit ​​the snap-fit ​​tube 8. A return spring 27 is installed between the outer wall of the directional ring 13 and the snap-fit ​​tube 8. An upward push block 28 is installed at the bottom of the pressure groove 14. The return spring 27 pushes the directional ring 13 and the upward push block 28, and pushes the rocker plate 12 in the opposite direction.

[0035] More specifically, residual powder from the 3D printer enters the feed box assembly 1 through the feed pipe 23 on the top cover 22. The feed hammering mechanism starts working, and the hydraulic cylinder 6 drives the hammering block 7 to periodically hammer the surface of the feed box to prevent residual powder from accumulating and clumping. After being filtered by the filter assembly 24, qualified powder falls into the collection box at the bottom. The filter assembly 24 can be quickly installed and removed through the filter installation mechanism, which is convenient for cleaning and replacement. The snap-fit ​​auxiliary mechanism ensures the stability and reliability of the filter assembly 24 installation, while providing a precise pressure adjustment function. The residual powder in the collection box can be removed through the box cover 21. When it is necessary to clean or replace the filter assembly 24, the position of the directional ring 13 is adjusted through the snap-fit ​​auxiliary mechanism to release the lock between the rocker plate 12 and the slot 10, so that the filter assembly 24 can be quickly removed. The whole system operates stably, is easy to operate and maintain, and can effectively solve the problem of residual powder recovery during 3D printing.

[0036] In summary, during the use or operation of the overall equipment: when the feeding and hammering mechanism is in operation, the fixed frames 3 at both ends of the feeding box assembly 1 support the rotating plate through the connecting frame 4. The hydraulic cylinder 6 controls the reciprocating motion of the rotating plate. When the hydraulic cylinder 6 extends, it drives the rotating plate to rotate around the connecting frame 4, so that the hammering block 7 installed at the end of the rotating plate contacts the surface of the feeding box assembly 1 to realize the hammering action. When the hydraulic cylinder 6 retracts, the rotating plate returns to its original position, and the hammering block 7 leaves the surface of the feeding box. This periodic hammering action can prevent residual powder from clumping or adhering in the feeding box and ensure that the residual powder falls smoothly into the filter box 2.

[0037] When the filter installation mechanism is in operation, the filter assembly 24 is connected to the clamping pipe 8 on the mating plates 26 at both ends of the filter box 2 via the clamping rod 9 on the mounting plate 25. When the clamping rod 9 is inserted into the clamping pipe 8, the groove 10 on the side wall of the clamping rod 9 engages with the rocker plate 12 inside the clamping pipe 8. When the directional ring 13 slides on the outer wall of the clamping pipe 8, the pressure groove 14 on it presses against the rocker plate 12, causing the other end of the rocker plate 12 to rock into the groove 10. At the same time, the clamping rod 9 presses the stabilizing spring 11 inside the clamping pipe 8, forming a stable three-point support structure, which realizes the quick installation and reliable fixation of the filter assembly 24.

[0038] When the locking auxiliary mechanism is in operation, the rotating ramp 15 on the outer wall of the locking tube 8 cooperates with the spring block 20 on the fixed block 19 through the rotating ring 17. The pressing groove 18 on the rotating ring 17 causes the spring block 20 to extend step by step, ensuring the stable rotation of the rotating ramp 15. When the rotating ramp 15 rotates, the directional ring 13 is moved by the top ramp 16, realizing precise control of the pressure on the rocker plate 12. The reset spring 27 provides a reverse thrust between the directional ring 13 and the outer wall of the locking tube 8, which acts on the rocker plate 12 through the push block 28 to realize the locking and unlocking, and realize the quick disassembly of the filter assembly 24.

[0039] Excess powder from the 3D printer enters the feed box assembly 1 through the feed pipe 23 on the top cover 22. The feed hammering mechanism starts working, and the hydraulic cylinder 6 drives the hammering block 7 to periodically hammer the surface of the feed box to prevent excess powder from accumulating and clumping. After being filtered by the filter assembly 24, qualified powder falls into the collection box at the bottom. The filter assembly 24 can be quickly installed and removed through the filter installation mechanism, facilitating cleaning and replacement. The snap-fit ​​auxiliary mechanism ensures the stability and reliability of the filter assembly 24 installation, while providing precise pressure adjustment. Excess powder in the collection box can be removed through the cover 21. When it is necessary to clean or replace the filter assembly 24, the position of the directional ring 13 is adjusted through the snap-fit ​​auxiliary mechanism to release the lock between the pry bar 12 and the slot 10, allowing for quick removal of the filter assembly 24. The entire system operates stably, is easy to operate and maintain, and can effectively solve the problem of excess powder recovery during 3D printing.
