Description

Technical Field

[0001] The invention relates to the technical field of 3D printing nozzles, and in particular to a 3D printer nozzle cooling device. Background Art

[0002] The 3D printer nozzle is one of the core components of 3D printing technology. It is responsible for spraying or extruding the material layer by layer according to the design requirements to form a three-dimensional entity. The principle of the nozzle mainly involves material supply, heating and injection control. First of all, material supply is one of the key functions of the nozzle. Commonly used 3D printing materials include thermoplastics, metal powders, ceramic materials, etc. The nozzle introduces the material into the nozzle through a thin pipe. In normal production, the nozzle usually needs to be cooled to prevent the inner wall of the nozzle from being damaged by high temperature on the one hand, and on the other hand, to prevent the 3D printing material inside the nozzle from being heated, causing its fluidity to be too strong and difficult to shape.

[0003] Publication No.: 202120621799 discloses a 3D printer nozzle heat dissipation device, characterized in that it includes a carrier frame, a first piston is provided on the top of the carrier frame, a second piston is provided on the bottom of the carrier frame, and the first piston and the second piston are fixedly connected to the carrier frame, four mounting plates are provided on the top surface of the carrier frame, and the mounting plates are fixedly connected to the carrier frame, telescopic columns are provided on both sides of the carrier frame, and the telescopic columns and the carrier frame are fixedly connected, springs are provided on the outside of the telescopic columns, protective plates are provided at the ends of the telescopic columns, and the protective plates and the telescopic columns are fixedly connected, cooling fans are provided on both sides of the carrier frame, and fixed plates are provided on both sides of the cooling fan. However, in actual use, the device and the existing equipment do not process the 3D ink inside the print nozzle when cooling the print nozzle, and the 3D ink adheres to the inner wall of the print nozzle, which makes the actual ventilation and heat dissipation effect of the print nozzle extremely poor, thereby resulting in poor actual heat dissipation effect of the device, and the heat dissipation quality of the print nozzle of the existing equipment has further room for improvement.

In the initial state, there is a gap between the blocking plate 310 and the limiting disk 31, so that the 3D printing ink can be normally transported. At this time, the first screw 301 drives the blocking plate 310 to move and blocks the limiting disk 31, thereby isolating the 3D printing ink inside the print head 3 from the inkjet location of the print head 3. Then, the control center 13 controls the second linear drive assembly 53 to drive the second output rod 530 and the clamping head 531 to reset, so as to fix the position of the blocking plate 310. The rotation of the first toothed disk 511 can drive the two second toothed disks 520 rotates, and the second toothed disc 520 rotates through the second output shaft 521 to drive the fan blades 522 to rotate. Since the number of teeth of the first toothed disc 511 is greater than the number of teeth of the second toothed disc 520, that is, the first toothed disc 511 rotates one circle to drive the second toothed disc 520 to rotate several circles, so as to ensure that the fan blades 522 can blow air normally at the blowing head 50, and the blown air directly blows on the surface of the printing nozzle 3, and performs preliminary cooling treatment on the printing nozzle 3, so as to avoid cooling the printing ink together during the cooling process, reduce the fluidity of the 3D ink, and reduce the quality of subsequent printing, thereby improving the cooling effect and cooling quality of the device, and facilitating user use; In the step where the first rotating drive assembly 40 is turned on and drives the first rotating shaft 400 to rotate, and the first rotating shaft 400 rotates to drive the first movable wheel 401 and the first fixed rod 41 to rotate, the first movable wheel 401 rotates and drives the first fixed rod 41 to rotate, the first fixed rod 41 rotates and drives the first adjusting arm 410 and the movable rod 411 to rotate, the movable rod 411 rotates and drives the second adjusting arm 412, the second fixed rod 413 and the first bevel gear 414 to rotate, and in the process where the movable rod 411 drives the second adjusting arm 412, the second fixed rod 413 and the first bevel gear 414 to rotate, the rotation of the movable rod 411 drives the return groove plate 43 to perform a linear reciprocating motion, the movement of the return groove plate 43 drives the movable plate 430 to move, and the movement of the movable plate 430 drives the piston plate 431 to perform a linear reciprocating motion in the storage bin 44, and when the piston plate 431 moves downward, the air pressure in the storage bin 44 increases, and the storage The cooling oil in the storage bin 44 is transported to the cooling groove 32 in the print head 3 through the delivery pipe 440. The pressure difference generated by the movement of the piston plate 431 in the storage bin 44 is sufficient to ensure that the cooling oil can be transported normally. The cooling oil in the cooling groove 32 that originally adsorbed the temperature of the print head 3 is transported to the fixed bin 45 through the conversion pipe 450. The cooler in the fixed bin 45 cools down this part of the cooling oil. The second one-way valve is used to prevent the cooling oil in the storage bin 44 from flowing back. When the piston plate 431 moves upward, the air pressure in the storage bin 44 decreases. The storage bin 44 extracts the cooling oil in the fixed bin 45 into the storage bin 44 for replenishment through the extraction pipe 441. The inner wall of the print head 3 absorbs heat and cools down by the cooling oil introduced in the above steps. The device can ensure that the interior of the print head 3 is always in a state of absorbing heat and cooling the cooling oil, thereby improving the cooling effect and cooling quality of the device and facilitating user use. In the above steps, the first bevel gear 414 rotates to drive the second bevel gear 460 to rotate, and the second bevel gear 460 rotates to drive the second screw 461 to rotate. In the initial position, the grinding assembly 49 is at the top of the processing chamber 48, and the second screw 461 rotates to drive the movable block 462 to move upward, and the movable block 462 moves to drive the electric turntable 463, the connecting shaft, and the mounting member 47 to move upward until the grinding assembly 49 contacts the bottom of the print nozzle 3. At this time, the control center 13 is used to open the grinding assembly 49 to clean the part of the bottom of the print nozzle 3 that is adhered by 3D ink. After the cleaning is completed, the movable block 462 is reset, and the control center 13 is used to open the electric turntable 463 to drive the mounting member 47 to rotate 180 degrees through the connecting shaft. Ten degrees, at this time, the processing chamber 48 is at the top, and the bottom grinding assembly 49 is at the bottom. The above steps are repeated to move the processing chamber 48 upward. During this period, the second rotary drive assembly 482 is turned on by the control center 13. The second rotary drive assembly 482 is turned on to drive the second rotating shaft 483 to rotate. The second rotating shaft 483 rotates to drive the first linear drive assembly 484 to rotate. The first linear drive assembly 484 rotates to drive the limit plate 486 to rotate through the first output rod 485. In the initial case, the limit plate 486 is connected to the second annular sleeve 481 through the clamping rod 4860 and the clamping groove. At this time, the rotation of the limit plate 486 can drive the second annular sleeve 481 to rotate through the clamping rod 4860 and the clamping groove. The rotation of the second annular sleeve 481 drives The push rod 4881 and the scraper wheel 4882 rotate. As the movable block 462 continues to move, the scraper wheel 4882 enters the interior of the print head 3 and scrapes and cleans the inner wall of the print head 3 to prevent the 3D printing ink adhering to the inner wall of the print head 3 from interfering with the normal heat dissipation of the print head 3. When the special arrangement of the inner wall of the print head 3 makes it difficult for the scraper wheel 4882 to contact the inner wall of the print head 3, the control center 13 is used to turn on the first linear drive assembly 484. The first linear drive assembly 484 is turned on to drive the first output rod 485, the limit plate 486, and the clamping rod 4860 to move upward. At this time, the clamping rod 4860 is separated from the clamping slot, and the limit plate 486 moves to drive the first output shaft 487 and the third bevel gear 4870 to move upward. The second rotary drive assembly 482 is rotated until the third bevel gear 4870 is meshed with the two fourth bevel gears 488. At this time, the continued rotation of the second rotary drive assembly 482 can drive the two fourth bevel gears 488 to rotate. The rotation of the fourth bevel gear 488 drives the third screw 4880 to rotate. The rotation of the third screw 4880 drives the push rod 4881 to move. The movement of the push rod 4881 drives the scraper wheel 4882 to move. Therefore, the device can adjust the cleaning range of the print nozzle 3 according to the structural size of the print nozzle 3. The device improves the heat dissipation effect of the print nozzle 3 by cleaning the 3D printing ink adhered to the inner wall of the print nozzle 3, so that the device can comprehensively cool the print nozzle 3, improve the cooling effect and cooling quality of the device, and facilitate user use.
