Description

Technical Field

[0001] This application relates to the field of 3D printing, and more particularly to a hydrogel 3D printing device. Background Art

[0002] Our company's previous hydrogel 3D method is as Figure 15 shown. It usually fills the cavity 200 of the placement shell with printing materials. Therefore, after printing is completed, a large amount of printing materials will be wasted. In view of the above technical defects, our company adopts droplet printing, that is, it no longer fills the placement shell with printing materials, but adds some printing materials in the center of the feeding part 40 to meet the printing requirements, thus avoiding waste of printing materials. In addition, it should be noted that an external glass plate is also provided at 200, and the external glass plate is fixed on the external platform, and the placement shell covers the external platform, so as to close the bottom of the cavity 200 through the external glass plate. Those skilled in the art should understand that after the device is printed multiple times, the glass used to close the bottom of the cavity 200 on the existing device needs to be replaced, which makes the replacement of the glass plate rather troublesome, while the invention only needs to take out the feeding part. Among them, the heating method of the existing hydrogel 3D printing platform usually adopts hot air heating or electric heating sheet method, but the heating effect of the above methods is not uniform in actual application, thus affecting the printing effect. The invention adopts the method of silicone oil heating, and its bottom is evenly heated, and the effect is better than the current mainstream heating method in the market.

[0003] Therefore, there is a need to provide a hydrogel 3D printing device with less consumption of printing materials, convenient disassembly and assembly, good heating effect, and capable of manually adding printing materials. Summary of the Invention

[0048] Specifically, the heating device 20 includes a second platform 21, which is fixed on the first platform 11, and the bottom of the first platform 11 is also separated from the second platform 21 by a predetermined distance. In addition, the heating device 20 also includes a heating plate 22, which is fixed at the bottom of the second platform 21, and the heating plate 22 is annular. In addition, the center of the second platform 21 also has a silicone oil tank 2101, wherein those skilled in the art should understand that the silicone oil tank 2101 is used to fill silicone oil, and the sealing method of the silicone oil tank 2101 can be achieved by two spaced glass plates, thereby limiting the position of the silicone oil in the silicone oil tank 2101. In addition, it should be noted that a first insertion hole 2102 and a second insertion hole 2103 are also provided on one side of the second platform 21, and the first insertion hole 2102 and the second insertion hole 2103 are both connected to the silicone oil tank 2101. It should be noted that the first insertion hole 2102 and the second insertion hole 2103 can be used as an oil filling port.

[0049] It is worth mentioning that the hydrogel 3D printing device also includes a pressure relief component 30, which is arranged at the first insertion hole 2102. That is, those skilled in the art should understand that the second platform 21 is configured to be heated by its built-in heating plate 22, so that the silicone oil in the silicone oil cabin 2101 expands, so that the expanded silicone oil can be guided to the pressure relief component 30.

[0050] Specifically, the pressure relief assembly 30 includes a first connecting stud 31, which is threadedly connected to the first insertion hole 2102, wherein the first connecting stud 31 is a hollow stud, and a first adapter 32 is fixed to the side of the first connecting stud 31 away from the second platform 21, wherein the first adapter 32 is a right-angle air pipe.

[0051] Furthermore, the pressure relief assembly 30 further includes a first air pipe 33 , one end of which is disposed at an end of the first adapter 32 away from the first connecting stud 31 , and the other end of the first air pipe 33 vertically extends a predetermined distance.

[0052] Further, the pressure relief component 30 further includes a second adapter 34. One end of the second adapter 34 is fixedly connected to the end of the first air pipe 33 that is away from the first adapter 32, and the other end extends a predetermined distance in a direction away from the first air pipe 33. It should be noted that the above-mentioned second adapter 34 is a hollow pipe fitting, and the first air pipe 33 can be fixed on the second adapter 34 by an interference fit method.

[0053] Further, the pressure relief component 30 further includes a second air pipe 35. One end of the second air pipe 35 is also fixedly connected to the end of the second adapter 34 that is away from the first air pipe 33, and the other end extends a predetermined distance in a direction away from the second adapter 34. The connection method between the second air pipe 35 and the second adapter 34 is the same as the connection method between the first air pipe 33 and the second adapter 34. It should be noted that the above-mentioned first air pipe 33 can be a plastic pipe, and the second air pipe 35 can be a silicone hose, that is, a flexible hose. Moreover, one end of the second air pipe 35 that is away from the second adapter 34 also has a plug to block the second air pipe 35. Specifically, when the silicone oil in the silicone oil tank 2101 expands, so that the expanded silicone oil can be guided to the pressure relief component 30, the second air pipe 35 will expand, so as to ensure that the pressure in the silicone oil tank 2101 will not be too high.

[0054] In addition, it should be noted that the pressure relief component 30 further includes a support frame 36. The support frame 36 is fixed on the wall surface of the second platform 21 where the first insertion hole 2102 is provided. It has a guiding cavity, and the first connecting stud 31, the first adapter 32, the first air pipe 33 and the second adapter 34 are all placed in the guiding cavity.

[0055] It is worth mentioning that a connecting pipe and a pipe disassembly plug 37 placed on the connecting pipe are further provided in the second insertion hole 2103, that is, the connecting pipe is threadedly connected to the second insertion hole 2103. In addition, the user can manually disassemble the pipe disassembly plug 37. Specifically, when there are trace bubbles in the silicone oil tank 2101, the user can manually place the second platform 21 vertically, then pull out the pipe disassembly plug 37, and press the second air pipe 35, so that the bubbles are discharged from the connecting pipe, and then install the pipe disassembly plug 37 and continue to use.

[0056] Specifically, the hydrogel 3D printing device further includes a material feeding member 40, which is placed in the silicone oil chamber 2101 and is in contact with the glass plate on the upper side of the silicone oil chamber 2101. When the heating plate 22 heats the second platform 21, the silicone oil in the silicone oil chamber 2101 can quickly conduct heat to the material feeding member 40, and the above-mentioned material feeding member 40 is used to place the printing material, that is, printing is carried out by means of photocuring.

[0057] In addition, it should be noted that a plurality of evenly distributed first magnetic blocks are provided on the top of the second platform 21, and the plurality of first magnetic blocks are arranged in a rectangular array. The hydrogel 3D printing device further includes a mist guiding shell 50, which is arranged on the second platform 21 and cooperates with the plurality of first magnetic blocks, that is, the mist guiding shell 50 is limited on the second platform 21 by means of magnetic attraction. In addition, the mist guiding shell 50 is annular, and at the same time, the material feeding member 40 is located at the center of the mist guiding shell 50, and the mist guiding block is connected to the pipeline of an external humidifier, that is, when water mist is sprayed onto the printing material on the material feeding member 40 through the mist guiding shell 50, the humidity of the printing material is ensured.

[0058] Specifically, the hydrogel 3D printing device further includes two locking devices 60, which are arranged oppositely and are spaced apart by a predetermined distance. Both of the two locking devices 60 are located on the top of the second platform 21 and on both sides of the material feeding member 40, and the two locking devices 60 are arranged to limit the position of the material feeding member 40.

[0059] Furthermore, each of the locking devices 60 includes a rotating rod 61, two elastic members 62 and a collar 63. The two elastic members 62 are both located under the collar 63 and are both arranged on the rotating rod 61. The rotating rod 61 is vertically arranged, and one end of the rotating rod 61 is rotatably connected to the top of the second platform 21. Specifically, the second platform 21 has a mounting hole that cooperates with the end of the rotating rod 61 to limit the position of the rotating rod 61. In addition, it should be noted that the rotating rod 61 also has an annular protrusion 611, and the annular protrusion 611 is located between the two elastic members 62.

[0060] Further, each of the locking devices 60 includes a rotating block 64. The top of the rotating block 64 has a stepped hole 6401 that penetrates the rotating block 64. The annular bump 611 cooperates with the bottom of the stepped hole 6401. Meanwhile, one of the elastic members 62 faces the stepped hole 6401 and abuts against the bottom of the rotating block 64, and the other end cooperates with the second platform 21 to define the distance between the rotating block 64 and the second platform 21. The rotating rod 61 also passes through the stepped hole 6401, and the other elastic member 62 is also placed at the top of the stepped hole 6401. The collar 63 is located above the rotating block 64 to limit the elastic member 62 located at the top of the stepped hole 6401. It should be noted that the connection manner between the collar 63 and the rotating rod 61 includes but is not limited to threaded connection. The elastic member 62 located at the top of the stepped hole 6401 is in frictional contact with the side wall forming the stepped hole 6401. At the same time, the connection manner between the rotating rod 61 and the second platform 21 can be implemented as a threaded connection. That is, when the user tightens the rotating rod 61, the collar 63 will move downward a predetermined distance, thereby squeezing the elastic member 62 located at the top of the stepped hole 6401, thereby preliminarily limiting the position of the rotating block 64. Additionally, during the process of rotating the rotating rod 61, since the elastic member 62 located at the top of the stepped hole 6401 is in frictional contact with the side wall forming the stepped hole 6401, it will drive the rotating block 64 to deflect a predetermined angle, facilitating the use of the locking device 60. Regarding how to use it conveniently, it is described as follows. The bottom of the rotating block 64 also has an abutting portion 641. One side of the abutting portion 641 away from the rotating rod 61 has an arc-shaped pressing surface. That is, when the user rotates the rotating rod 61, the rotating block 64 is configured to swing a predetermined distance in a direction close to or away from the feeding member 40. When the rotating block 64 swings a predetermined angle in a direction close to the feeding member 40, the arc-shaped pressing surface will contact and abut against the side wall of the feeding member 40, making the rotating block 64 unable to rotate. At this time, the user continues to rotate the rotating rod 61 to make the collar 63 press down, thereby squeezing the rotating block 64 to limit the position of the rotating block 64. At the same time, the ends of the two rotating blocks 64 close to each other will be located above the feeding member 40 to limit the position of the feeding member 40. Conversely, when the rotating block 64 swings a predetermined angle in a direction away from the feeding member 40, the ends of the two rotating blocks 64 close to each other no longer limit the position of the feeding member 40. That is, through the above method, the operation convenience of the locking assembly is improved. Additionally, it should be noted that a knob is provided at the top of the rotating rod 61, and the user can conveniently adjust the locking assembly through the knob.

[0061] The hydrogel 3D printing device also includes a lifting assembly 70, which is arranged on the top of the base 10, and the lifting assembly 70 includes a frame 71, which is vertically arranged and fixed on the top of the base 10, and the frame 71 is also spaced a predetermined distance from the second platform 21. It is worth mentioning that the lifting assembly 70 also includes a driving assembly 72 and a support arm 73. The driving assembly 72 is arranged on the frame 71, and the support arm 73 cooperates with the driving assembly 72. Specifically, the driving assembly 72 is configured to drive the support arm 73 to move up and down a predetermined distance, that is, the implementation method of the driving assembly 72 can be implemented as a motor, a lead screw and a slider. At the same time, the frame 71 also has a strip mounting groove, and the motor, the lead screw and the slider are all arranged in the strip mounting groove, and the motor is close to the top of the frame 71. In addition, the motor cooperates with the lead screw, and the slider is placed on the lead screw. It should be understood by those skilled in the art that when the above-mentioned motor is operating, the lead screw rotates, and the slider moves up or down a predetermined distance, and the support arm 73 moves up or down a predetermined distance synchronously.

[0062] Specifically, the hydrogel 3D printing device further includes a print head assembly 80, which is mounted on a side of the support arm 73 away from the drive assembly 72. Specifically, the print head assembly can move downward by a predetermined distance so that the print head assembly can face the printing material on the material placing member 40. The print head assembly includes a quick-release head 81, and the quick-release head 81 cooperates with the end of the support arm 73 away from the drive assembly 72. Specifically, the top of the support arm 73 has a positioning hole, and the positioning hole is located at the end of the support arm 73 away from the drive assembly 72. At the same time, the quick-release head 81 has a matching cavity 8102 at the end close to the support arm 73, and the top of the quick-release head 81 has a strip notch 8101. The strip notch 8101 and the matching cavity 8102, that is, the end of the support arm 73 is slidably placed in the matching cavity 8102, and the positioning hole is located in the strip notch 8101. At this time, the user can use an external hand-tightening screw 82 to threadably connect with the positioning hole and squeeze the top of the quick-release head 81, so as to limit the position of the quick-release head 81.

Among them, the connection mode between the connecting piece 83 and the quick-release head 81 can be implemented as a screw connection, and the connection mode between the connecting piece 83 and the heat conducting plate can also be implemented as a screw connection. In addition, a heat insulating washer is provided at the connection between the external screw and the connecting piece 83, so as to facilitate the heat to be guided to the quick-release head 81 through the connecting piece 83.

[0064] Further, the print head assembly 80 further includes a heating block 87, the heating block 87 is magnetically connected to the side of the heat conducting block 84 close to the frame 71.

In addition, it should be noted that the implementation modes of the heating block 87 and the heat conducting block 84 can also be changed, that is, the heat conducting block 84 is cancelled, and the heating block 87 is directly matched with the two connecting pieces 83, thereby improving the heating efficiency. It is worth mentioning that the present invention has a temperature control module 100 as Figure 1 shown, and the heating block 87 can be combined with the temperature control module 100.

[0065] In addition, it should be noted that the print head assembly 80 further includes a hydrogel forming platform 86, the structure of which is as Figure 13 shown, and the hydrogel forming platform 86 is matched with the bottom of the heat conducting block 84 or the bottom of the heating block 87, and its connection mode can be specifically implemented as a magnetic connection. In addition, a diversion groove 8601 is further provided on one side of the hydrogel forming platform 86, and the structure of the diversion groove 8601 is as Figure 12 and 13 shown in two implementation modes, that is, during printing, the user can add a small amount of printing material on the feeding part 40, and then the user can add printing material through the diversion groove 8601 according to the subsequent printing situation, thereby effectively reducing the waste of printing material in this way.
