Description

Technical Field

[0001] The present invention relates to the technical field of 3D printers, and in particular to a cooling device applied to 3D printing equipment. Background Art

[0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis and uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. 3D printing is usually achieved using a digital technology material printer. It is often used to make models in the fields of mold manufacturing, industrial design, etc., and then gradually used for the direct manufacturing of some products. There are already parts printed using this technology. This technology has been used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automobiles, aerospace, dental and medical industries, education, geographic information systems, civil engineering and other fields. There are many types of 3D printers on the market, but most of them are overall box-type structures, but in the long run, they are not as durable as before. During long-term use, the 3D printer will generate a lot of heat. If it cannot be quickly discharged in time, it will cause great damage to the internal parts, and in severe cases, the 3D printer will be burned. The existing equipment generally cools it down by air cooling. For example, the patents No.: CN202320701114.3 and CN201910274364.1 both use air cooling for cooling. When cooling, the air cooling uses the fan blades to drive the flow of air to dissipate heat. Although air cooling can dissipate heat, in actual use, the effect of dissipating heat only by the gas generated by the fan blades is relatively poor, and it cannot be cooled quickly, resulting in poor effect of the equipment during use, thereby affecting the cooling efficiency of the equipment.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 8 , the present invention provides a technical solution:

[0029] A cooling device for 3D printing equipment comprises a shell 1, a cooling chamber 2 is provided inside the shell 1, a plurality of air holes 3 are provided on the inner wall of the shell 1, the air holes 3 and the cooling chamber 2 are connected in a through manner, a workbench 4 is installed in the shell 1, a print head 5 is provided in the shell 1, an air cooling mechanism 6 is installed on the shell 1, an alternating mechanism 10 is provided in the cooling chamber 2, two placement trays 19 are provided on the alternating mechanism 10, a return pipe 21 is fixedly connected to the lower side of the placement tray 19, a circulation mechanism 26 is installed on the shell 1, the return pipe 21 is connected in a through manner to the circulation mechanism 26, an ice maker 30 is installed on the shell 1, the ice maker 30 and the circulation mechanism 26 are connected in a through manner, a closing mechanism 31 is provided on the shell 1, and a driving mechanism 34 is provided on the shell 1, and the driving mechanism 34 is movably connected to the air cooling mechanism 6, the alternating mechanism 10 and the closing mechanism 31 respectively;

[0030] During operation, the printing head 5 can print materials on the workbench 4, and during the printing process, the ice maker 30 is controlled to make ice cubes. When the ice cubes are made, the driving mechanism 34 is controlled to be connected with the closing mechanism 31 for transmission. At this time, the placing tray 19 on the alternating mechanism 10 is located at the lower side of the ice maker 30, and when the driving mechanism 34 controls the closing mechanism 31 to open, the ice cubes made in the ice maker 30 enter the placing tray 19. When the materials enter the placing tray 19, the driving mechanism 34 controls the alternating mechanism 10 to work, so that the alternating mechanism 10 moves the placing tray 19 containing the ice cubes to one side of the air cooling mechanism 6. At the same time, the ice maker 30 can make ice cubes again. When the placing tray 19 moves to one side of the air cooling mechanism 6, the driving mechanism 34 is controlled to be connected with the air cooling mechanism 6 for transmission. At this time, the driving mechanism 34 controls the air cooling mechanism 6 to work, thereby promoting the flow of air. When the air flows, the air first moves the ice cubes placed in the placing tray 19 to the side of the air cooling mechanism 6. The cold air is agitated to enter the cooling chamber 2, and at the same time, the cold air is transported to the inner side of the shell 1 through the air vents 3 on the cooling chamber 2, thereby completing the cooling of the device during printing. At the same time, when the ice cubes are in the process of melting, the melting absorbs heat, which can cool the inside of the device at the same time. After the ice cubes melt, the liquid re-enters the circulation mechanism 26 through the reflux pipe 21, so that it is made into ice cubes again through the ice maker 30, and is moved to one side of the air cooling mechanism 6 through the alternating mechanism 10 again, thereby making the device more efficient during air cooling, and at the same time, it can further improve the quality of air cooling and accelerate the temperature drop. The melting of the ice cubes absorbs heat and cooperates with the cooling of the air cooling at the same time, further improving its cooling efficiency. The melted liquid is circulated for refrigeration, which can avoid waste of resources, so that the device can complete the temperature drop of the device when it is working, and can ensure the circulation of resources during its cooling, further improving the practicability and convenience of use of the device, and at the same time ensuring the use effect of the device.

[0031] As a further solution of the present invention, the air cooling mechanism 6 is located in the cooling chamber 2, and the air cooling mechanism 6 includes a shell 7, a drive shaft 8 and a fan blade 9. The shell 7 is installed on the housing 1, and the drive shaft 8 is rotatably connected in the shell 7, and the fan blade 9 is installed on the drive shaft 8;

[0032] During operation, when the driving mechanism 34 controls the driving shaft 8 to rotate, the driving shaft 8 controls the fan blades 9 to rotate, so that the fan blades 9 control the flow of air, thereby making the equipment more efficient and faster when cooling down.

[0033] As a further solution of the present invention, the alternating mechanism 10 includes a mounting seat 11, a guide groove 12, a support platform 13, a telescopic mechanism 14, a track wheel 15, a rack 16, a first rotating column 17 and a first gear 18. The mounting seat 11 is installed in the cooling chamber 2, and the guide groove 12 is opened on the mounting seat 11. The supporting platform 13 and the telescopic mechanism 14 are slidably connected in the mounting seat 11. The telescopic mechanism 14 is installed with a track wheel 15, and the track wheel 15 is slidably connected in the guide groove 12. The support platform 13 and the telescopic mechanism 14 are fixedly connected with a rack 16. The first rotating column 17 is rotatably connected in the mounting seat 11, and two first gears 18 are installed on the first rotating column 17. The first gear 18 and the rack 16 are meshed and connected, and the placement plate 19 is respectively located on the support platform 13 and the telescopic mechanism 14;

[0034] During operation, when the driving mechanism 34 controls the first rotating column 17 to rotate, the first rotating column 17 controls the two first gears 18 to rotate. At this time, the first gear 18 drives the two gears to move. When the two racks 16 move, the support platform 13 and the telescopic mechanism 14 move relative to each other. At the same time, the track wheel 15 on the telescopic mechanism 14 moves in the guide groove 12. When the support platform 13 and the telescopic mechanism 14 alternate, the track wheel 15 cooperates with the track groove to shorten the telescopic mechanism 14, so that the two placement platforms form an intersection. After the two placement platforms are interlaced, the two placement platforms can be on the same plane again, and then the placement platforms are always kept on one side of the air cooling mechanism 6. Then, the air cooling mechanism 6 can improve the air cooling efficiency of the equipment, further improve the cooling effect of the equipment when in use, and at the same time, it can absorb heat through the melting of ice cubes to increase the rate of temperature drop.

[0035] As a further solution of the present invention, the telescopic mechanism 14 includes a fixed seat 22, a sliding seat 23, a spring 24 and an electric lock plate 25. The mounting seat 11 is slidably connected to the sliding seat 23, the sliding seat 23 is slidably connected to the fixed seat 22, a spring 24 is provided between the fixed seat 22 and the sliding seat 23, the track wheel 15 is located on the fixed seat 22, and an electric lock plate 25 is provided between the fixed seat 22 and the sliding seat 23;

[0036] During operation, when the track wheel 15 moves in the guide groove 12, the track wheel 15 moves along the shape of the guide groove 12, and when the two placement plates 19 are staggered, the track wheel 15 pulls the fixed seat 22, so that the distance between the fixed seat 22 and the sliding seat 23 changes, and the length of the spring 24 is shortened. After the two placement plates 19 are staggered, the fixed seat 22 and the sliding seat 23 are reset, and then the two placement platforms are located on the same horizontal plane again, and then the ice cubes can be melted and cooled by air cooling at the same time, and at the same time they can melt and absorb heat by themselves, further improving the cooling efficiency of the equipment.

[0037] As a further solution of the present invention, a plurality of through holes 20 are provided on the placement plate 19, and the placement plate 19 is located on one side of the air cooling mechanism 6;

[0038] During operation, when the air flow in the air cooling mechanism 6 acts on the placement plate 19, the gas enters the placement plate 19 through the through hole 20, and at the same time the gas is discharged from the placement plate 19, thereby completing the cooling of the gas, and then reducing the temperature in the air flow, and then making the equipment more efficient when cooling.

[0039] As a further solution of the present invention, the circulation mechanism 26 includes a liquid storage tank 27, a liquid injection pipe 28 and a pump 29. The liquid storage tank 27 is installed on the housing 1, the liquid storage tank 27 is provided with a liquid injection pipe 28, the return pipe 21 is connected to the liquid storage tank 27, and the pump 29 is installed on the liquid storage tank 27;

[0040] During operation, when the ice melts, the liquid enters the liquid storage tank 27 through the reflux pipe 21. At this time, the pump 29 transports the liquid to the ice maker 30 to cool the liquid. After the liquid is cooled, it can enter the placement tray 19 again. This can be circulated multiple times, which can effectively improve the cooling efficiency of the equipment and ensure the recycling of resources.

[0041] As a further solution of the present invention, the closing mechanism 31 is located at the lower side of the ice maker 30, and the closing mechanism 31 includes a second rotating column 32, a closing plate 33 and a reversing wheel. Two second rotating columns 32 are rotatably connected to the housing 1, and the closing plate 33 is installed on the second rotating column 32. The housing 1 is provided with a reversing wheel, and one of the second rotating columns 32 is drivingly connected to the reversing wheel;

[0042] During operation, when the ice maker 30 completes ice making, the driving mechanism 34 controls the second rotating column 32 to rotate, and at the same time, the other second rotating column 32 performs reverse rotation through the reversing wheel. At this time, the two closing plates 33 move downward or upward at the same time, so as to complete their separation. When the two closing plates 33 are separated, the ice maker 30 transports the ice cubes to the placement tray 19, thereby achieving cooling inside the device. After the ice cubes are transported, the two closing plates 33 are closed again, thereby forming a closed space inside, which can effectively improve the cooling efficiency of the device.

[0043] As a further solution of the present invention, the driving mechanism 34 includes a third rotating column 35, a speed regulating box 36, a half gear 37, a fourth rotating column 38, a second gear 39, a torsion spring 40, a driving motor 41 and a telescopic rod 42. The third rotating column 35 and the fourth rotating column 38 are rotatably connected on the shell 1. The speed regulating box 36 is installed on the shell 1. The speed regulating box 36 and the third rotating column 35 are transmission-connected. The half gear 37 is installed on the alternating mechanism 10. The speed regulating box 36 and the alternating mechanism 10 are transmission-connected. The second gear 39 is installed on the fourth rotating column 38. The second gear 39 and the half gear 37 are meshingly connected. The fourth rotating column 38 is sleeved with a torsion spring 40. Another third rotating column 35 is rotatably connected to the shell 1. The other third rotating column 35 is transmission-connected to the air cooling mechanism 6. The driving motor 41 is installed on the shell 1. The output unit of the driving motor 41 is fixedly connected to the telescopic rod 42, and the telescopic rod 42 is movably connected to the two third rotating columns 35 respectively.

[0044] During operation, when the telescopic rod 42 is shortened, the telescopic rod 42 is engaged with another third rotating column 35, and the driving motor 41 drives another third rotating column 35 to rotate through the telescopic rod 42, thereby making the air cooling mechanism 6 work, thereby effectively accelerating the air cooling effect of the equipment, and when the telescopic rod 42 is extended, the telescopic rod 42 is engaged with one of the third rotating columns 35, and the driving motor 41 drives the speed regulating box 36 to work through the third rotating column 35, and the speed regulating box 36 drives the alternating mechanism 10 to work, and at the same time the speed regulating box 36 drives the alternating mechanism 10 to work through the semi-gear The wheel 37 drives the second gear 39 to rotate, so that the closing mechanism 31 opens. When the placement tray 19 moves to the lower side of the ice maker 30, the closing mechanism 31 is fully opened. At this time, the ice cubes enter the placement tray 19. Then the half gear 37 and the second gear 39 are disengaged, and the torsion spring 40 controls the closing mechanism 31 to close again. Then the alternating mechanism 10 is controlled to alternate again, so that ice cubes are placed in the two placement trays 19. Finally, the air cooling mechanism 6 is operated again to complete the reduction of the air cooling temperature, making it more efficient in cooling and further improving its cooling speed.
