Description

Technical Field

[0001] This invention relates to the field of 3D printing technology, and in particular to a self-cleaning 3D printing product device. Background Technology

[0002] 3D printing technology, as an additive manufacturing process, has been widely used in precision manufacturing, personalized customization, and many other fields. However, existing 3D printing devices mostly rely on manual methods for unloading the product and cleaning the worktable after printing. This is not only cumbersome and inefficient, but also prone to product damage or worktable contamination due to human contact, affecting the quality of subsequent prints. Furthermore, most devices are equipped with only a single worktable, requiring a shutdown for unloading and cleaning after printing, preventing continuous printing operations and severely limiting production efficiency. In addition, traditional unloading mechanisms often use a single clamping or pushing method, which is difficult to adapt to printed products of different sizes and shapes, and their cleaning function is weak, easily leaving dust and waste residue, affecting the cleanliness and operational stability of the device. To address these shortcomings, there is an urgent need for a 3D printing device that can achieve automatic unloading, efficient cleaning, and support continuous operation, in order to break through existing technological bottlenecks and improve the automation level and production efficiency of 3D printing.

[0036] The invention is used in the following manner: The invention has a reasonable and simple structure, low production cost, convenient installation, and complete functions. After the 3D printing mechanism 2 completes the preset printing task, the replaceable worktable 3 carrying the printed product is fixedly connected to its lower longitudinal moving part via a locking mechanism 4. At this time, the locking mechanism 4 is in a locked state, and the piston rods of several locking cylinders 41 are inserted into the locking holes 42 opened on the outer side of the corresponding fixing blocks 43, firmly fixing the replaceable worktable 3 to the moving part of the 3D printing mechanism 2; two rotary clamping conveying mechanisms 5 (located on the left and right sides of the chassis 1 respectively) Both the inner side of the side window are in standby mode, and the two unloading and cleaning mechanisms 6 (located on the outside of the corresponding rotary conveyor mechanism 5 and fixed on the outside of the chassis 1) are also in standby mode. After the entire device completes the printing stage, it enters the self-cleaning and continuous printing preparation stage. Then, the 3D printing mechanism 2 activates its lower longitudinal moving component to accurately move the replaceable worktable 3 fixed on it to the corresponding position of the clamping mechanism 52 of the right rotary conveyor mechanism 5, ensuring that the right edge of the replaceable worktable 3 is aligned with the clamping groove 521 of the clamping mechanism 52. At this time, the left rotary conveyor mechanism 5 is still... In standby mode, the clamping mechanism 52 is not performing a clamping action, and the left replaceable worktable 3 is not moving. Then, the clamping mechanism 52 of the right rotary clamping and conveying mechanism 5 starts to work. The hydraulic cylinder 526 is activated, and its piston rod pushes the connecting block 525 to move horizontally within the inner cavity 527 of the rotating seat 51. The inclined blocks 524 fixed on the upper and lower sides of the connecting block 525 move synchronously. The inclined blocks 524 slide and engage with the inclined grooves 523 on the clamping blocks 522, causing the upper and lower clamping blocks 522 to clamp into the clamping grooves 521, finally firmly clamping the right side of the replaceable worktable 3. Fixing; at the same time, the locking mechanism 4 unlocks, and the piston rods of several locking cylinders 41 retract synchronously, disengaging from the corresponding locking holes 42, releasing the fixation on the bottom of the replaceable worktable 3. At this time, the replaceable worktable 3 is only fixed by the clamping mechanism 52 of the right-side rotary clamping conveyor 5. Then, the motor 54 of the right-side rotary clamping conveyor 5 starts, and its output shaft drives the transmission shaft 53 to rotate. The rotating seat 51 fixed outside the transmission shaft 53 rotates synchronously, thereby driving the replaceable worktable 3 clamped by the clamping mechanism 52 to rotate slowly until the replaceable worktable 3 is in a vertical state.Subsequently, the clamping mechanism 55 of the right-side rotary conveying mechanism 5 is activated, and the piston rod of the second cylinder 551 extends downward, driving the fixed end of the clamping block 552 to move down, so that the clamping groove 553 on the lower side of the clamping block 552 engages with the upper edge of the vertically positioned replaceable worktable 3, thus performing secondary fixation on the replaceable worktable 3 to ensure its stability during the unloading and cleaning process. At this time, the rotating seat 51 stops rotating, the first motor 54 is turned off, and then the right-side unloading and cleaning mechanism 6 (fixed on the right side of the machine box 1) begins to work. First, the lifting drive mechanism 62 is activated, and the output shaft of the second motor 621 drives the second transmission shaft 622 to rotate. The drive gears 623 on both sides of the second transmission shaft 622 rotate synchronously, and the drive gears 623 and the upper side of the screw 625... The driven gear 624 engages with the drive gear, driving the screws 625 in the two guide grooves 626 to rotate synchronously. The screws 625 engage with the threaded holes in the center of the slides 627, driving the two slides 627 to move vertically along the guide grooves 626, thereby driving the connecting beam 63 fixed between the slides 627 to rise and fall synchronously, adjusting the height of the unloading and cleaning structure 64 so that it is aligned with the surface of the vertical replaceable worktable 3. When the unloading and cleaning structure 64 is working, the movable seat 642 is in the slide cavity 641 under the elastic force of the spring 644 and is pressed against the replaceable worktable 3. The shovel 645 on the lower left side of the movable seat 642 is pressed against the surface of the replaceable worktable 3. At the same time, the motor 649 starts, and its output shaft drives the transmission shaft 648 to rotate, thus driving the transmission... The cleaning wheels 647 fixed externally to shaft 3 648 rotate synchronously to wipe and clean the surface of the replaceable worktable 3; the shovel 645 scrapes off the printed products from the surface of the replaceable worktable 3, and the products slide down the frame 61 into the collection box 65. The buffer pad 66 on the bottom inner side of the collection box 65 cushions and protects the falling products to prevent damage; at the same time, the dust suction pipe 643 is activated, sucking in the dust and debris generated during the cleaning process through the opening of the mounting slot 646, achieving a comprehensive cleaning of the replaceable worktable 3. During the cleaning process, the connecting beam 63 continuously rises and falls to ensure that the entire surface of the replaceable worktable 3 is cleaned. While the right unloading and cleaning mechanism 6 unloads and cleans the right replaceable worktable 3, the left side... The rotary clamping conveyor 5 is activated, and its working process is the same as the initial clamping process of the right rotary clamping conveyor 5. The motor 54 drives the transmission shaft 53 and the rotating seat 51 to rotate, so that the left clamping mechanism 52 is adjusted to a horizontal state. Then, the hydraulic cylinder 526 pushes the connecting block 525 and the inclined block 524 to move, which drives the clamping block 522 to clamp the left replaceable worktable 3. After that, the rotating seat 51 of the left rotary clamping conveyor 5 rotates, moving the left replaceable worktable 3 to the corresponding position of the longitudinal moving part under the 3D printing mechanism 2. Then, the locking mechanism 4 is activated, and the piston rods of several locking cylinders 41 extend and insert into the locking holes 42 of the bottom fixing block 43 of the left replaceable worktable 3, so as to firmly fix the left replaceable worktable 3.Simultaneously, the clamping mechanism 52 of the left rotary conveyor mechanism 5 is released, and the locking mechanism 55 is reset, returning to the standby state. At this time, the 3D printing mechanism 2 can immediately start the next printing task to achieve continuous printing. After the unloading and cleaning of the right replaceable worktable 3 is completed, the lifting drive mechanism 62 of the right unloading and cleaning mechanism 6 drives the connecting beam 63 and the unloading and cleaning structure 64 to reset, the second motor 621 and the third motor 649 are turned off, and the dust suction pipe 643 stops working; the locking mechanism 55 of the right rotary conveyor mechanism 5 is reset (the piston rod of the second cylinder 551 retracts, and the locking block 552 disengages from the replaceable worktable 3), and the clamping mechanism 52 is released (the piston rod of the first cylinder 526 retracts, and the connecting block 525 and the inclined block 552 disengage from the replaceable worktable 3). 24. Reset (clamping block 522 opens), motor 54 drives the rotating seat 51 and the replaceable worktable 3 to rotate and reset to a horizontal state. Then, the printed product in the collection box 65 can be manually removed, or the cleaned replaceable worktable 3 can be moved to a designated location for later use. The right-side rotary clamping conveyor 5 returns to standby mode, awaiting the next unloading and cleaning task. In summary, throughout the entire process, all components work together. Through the alternating switching of the replaceable worktable 3, the conveying and positioning of the rotary clamping conveyor 5, and the automatic unloading and cleaning of the unloading and cleaning mechanism 6, 3D printing and unloading / cleaning are synchronized. This improves printing efficiency, avoids the tediousness of manual cleaning, and ensures the continuous and stable operation of the device.
