Description

Technical Field

[0001] The present invention relates to the technical field of additive manufacturing equipment, and specifically relates to an additive manufacturing equipment for processing automotive plastic parts. Background Art

[0002] Additive manufacturing technology is a technology for manufacturing solid parts by gradually adding materials. Compared with the traditional material removal - cutting processing technology, it is a "bottom-up" manufacturing method. The familiar 3D printing technology is an embodiment of additive manufacturing technology. Existing additive manufacturing equipment or 3D printing equipment usually adopts a three-axis movement method, and realizes layer-by-layer stacking printing by heating and melting filamentous consumables, and finally processes the designed 3D items.

[0003] However, in order to ensure the effect of the 3D printing equipment, it is necessary to ensure the horizontal placement of the device. However, existing 3D printing equipment is usually not convenient for horizontal adjustment for different placement areas, which may affect the subsequent leveling of the printing surface. At the same time, during the printing process of the equipment, in order to make the finished product have different colors, filamentous consumables of different colors will be used. Adding consumables to existing equipment is relatively inconvenient, and it is not convenient to adjust the placement position according to needs. And the filamentous consumables usually have a certain hardness and toughness, which may cause the filamentous consumables on the winch to shift or even break away when the height of the print head rises, affecting the addition of consumables.

Detailed implementation mode

[0035] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0036] As Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 As shown in

[0037] Specifically, as Figure 1 、 Figure 3 、 Figure 7As shown, the leveling structure 2 includes support feet 205. A plurality of support feet 205 are slidably connected to the bottom side of the printer body 1. A first spring 206 is fixedly connected between the end of the support foot 205 and the printer body 1. An engagement groove 207 is formed in the side surface of the support foot 205. A traction plate 202 is provided on the side surface of the support foot 205. A worm 204 is rotatably connected to the end of the traction plate 202. The side surface of the worm 204 is engaged with the support foot 205 through the engagement groove 207. There are four support feet 205, and the four support feet 205 are arranged in a square at the bottom side of the printer body 1. A bevel gear 203 is fixedly connected to the top end of the worm 204. A regulating rod 201 is engaged with the side surface of the bevel gear 203. The middle part of the regulating rod 201 is rotatably connected to the side surface of the printer body 1;

[0038] The user can rotate the regulating rod 201 corresponding to the support foot 205, drive the worm 204 connected to the bevel gear 203 to rotate through the regulating rod 201, and then drive the support foot 205 to move through the engagement groove 207 to adjust the support height of the current position of the printer body 1 and ensure the horizontal placement of the overall printer body 1.

[0039] Specifically, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 shown, the reset structure 3 includes a guide groove 306. A guide groove 306 is formed at the end of the traction plate 202. The traction plate 202 is slidably connected to the printer body 1. A third spring 305 is fixedly connected between the side surface of the traction plate 202 and the printer body 1. A reset rod 302 is rotatably connected to the middle of the printer body 1. The two sides of the reset rod 302 are slidably connected to the traction plate 202 through the guide groove 306 respectively. An adjusting cap 301 is slidably connected to the end of the reset rod 302. A second spring 304 is fixedly connected between the adjusting cap 301 and the printer body 1. The end of the adjusting cap 301 is of a square structure. A mating groove 303 is formed inside the printer body 1. The square end of the adjusting cap 301 is slidably connected to the printer body 1 through the mating groove 303;

[0040] Since the support height of the support feet 205 is adjusted by the adjusting rod 201, in order to facilitate the user to quickly reset the position of the support feet 205, the user can first press the adjusting cap 301 located on the side of the printer body 1, so that the square part at the end of the adjusting cap 301 disengages from the mating groove 303. At this time, the adjusting cap 301 can be rotated to drive the reset rod 302 to rotate. When the reset rod 302 rotates in any direction, the extended parts on both sides of the reset rod 302 will slide in the guiding grooves 306 on the corresponding traction plates 202, and at the same time, the traction plates 202 will be pulled, so that the worm 204 at the other end of the traction plate 202 disengages from the engaging groove 207 on the support feet 205. After losing the support, the support feet 205 will be reset under the traction of the first spring 206. At this time, the adjusting cap 301 is released, and the worm 204 on the traction plate 202 will re-engage with the engaging groove 207 on the support feet 205 under the traction of the third spring 305. At the same time, the square part at the end of the adjusting cap 301 will slide back into the mating groove 303 again. At this time, since the adjusting cap 301 will limit the rotation of the reset rod 302 to fix the position of the traction plate 202, the effect of resetting and fixing the support feet 205 is achieved. At this time, the user can adjust the support feet 205 again.

[0041] Specifically, as Figure 1 , Figure 4 , Figure 8 , Figure 9 shown, the installation structure 4 includes an installation arm 401. The top end of the printer body 1 is fixedly connected with the installation arm 401. The two sides of the installation arm 401 are respectively provided with side sliding grooves 404 in a "U" - shaped structure. The installation arm 401 is slidably connected with a sliding seat 402 through the side sliding grooves 404. A first abutting rod 407 is slidably connected to the middle of the sliding seat 402. The end of the first abutting rod 407 is in a triangular prism structure. A fifth spring 408 is fixedly connected between the first abutting rod 407 and the sliding seat 402. A tooth groove 403 is provided on the top side of the installation arm 401. The first abutting rod 407 abuts against the installation arm 401 through the tooth groove 403. A second abutting rod 412 is slidably connected to each side of the sliding seat 402. A sixth spring 411 is fixedly connected between the second abutting rod 412 and the sliding seat 402. A locking rod 405 is slidably connected to the middle of the sliding seat 402. A fourth spring 406 is fixedly connected between the locking rod 405 and the sliding seat 402. The adjacent ends of the first abutting rod 407, the second abutting rod 412 and the locking rod 405 are all hemispherical ends. First abutting grooves 409 are respectively provided on both sides of the locking rod 405. A second abutting groove 410 is provided on the bottom side of the locking rod 405. The hemispherical ends of the first abutting rod 407 and the second abutting rod 412 abut against the side surface of the locking rod 405;

[0042] The mounting arm 401 located on the top side of the printer body 1 is used to place consumables. The sliding seat 402 can slide in through the two ends of the side sliding groove 404 on the mounting arm 401. At the same time, a triangular locking rod 405 is provided on the bottom side of the sliding seat 402 to facilitate the adjustment and fixation of the position of the sliding seat 402. In order to further improve the fixing effect of the sliding seat 402 and ensure the stability of the device during printing, the user needs to keep pressing the locking rod 405 when sliding the sliding seat 402. At this time, the first contact groove 409 and the second contact groove 409 on the side of the locking rod 405 are pressed. The two interference grooves 410 will move to the positions of the second interference rod 412 and the first interference rod 407 respectively. Due to the existence of the interference grooves, the user can freely adjust the position of the sliding seat 402 on the mounting arm 401. After the adjustment is completed, the locking rod 405 is released. At this time, the interference grooves and the interference rod are separated from each other, so that the first interference rod 407 and the second interference rod 412 will directly interfere with the side of the locking rod 405, and the first interference rod 407 and the second interference rod 412 cannot slide, thereby fixing the position of the sliding seat 402 on the mounting arm 401.

[0043] Specifically, such as Figure 1 、 Figure 2 、 Figure 5 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 As shown, the locking structure 5 includes a turntable 501, the end of the sliding seat 402 is rotatably connected to the turntable 501, the middle of the sliding seat 402 is provided with a mounting shaft 506, both ends of the mounting shaft 506 are provided with a protruding structure, both sides of the sliding seat 402 are provided with a first receiving groove 507, the mounting shaft 506 is slidably connected to the sliding seat 402 through the first receiving groove 507, the protrusions at both ends of the mounting shaft 506 conflict with the inner side of the turntable 501, the middle of the turntable 501 is provided with a second receiving groove 508, the side of the turntable 501 is provided with a plurality of positioning grooves 505, the turntable 501 conflicts with the second conflicting rod 412 on the same side through the positioning grooves 505, the mounting shaft 506 is rotatably connected to the wire reel 503, the side of the wire reel 503 is fixedly connected to the consumable wire 502, and the side of the turntable 501 is rotatably connected to the guide block 504;

[0044] The middle part of the turntable 501 is used for placing the filament consumable. A guiding block 504 for guiding the filament consumable is arranged on the side of the turntable 501 to ensure smooth wire feeding of the print head at different heights. On the other hand, in order to facilitate the disassembly and assembly of the spool of the filament consumable, the mounting shaft 506 located in the middle of the turntable 501 is used to facilitate the rotation of the spool of the filament consumable. During installation, the user first needs to rotate the turntable 501 so that the second receiving groove 508 formed on the turntable 501 and the first receiving groove 507 on the sliding seat 402 are rotated to be aligned. At this time, the mounting shaft 506 can be directly taken out to install the spool of the filament consumable, which is convenient for operation.

[0045] Specifically, as Figure 5 , Figure 10 , Figure 11 , Figure 12 shown, the guiding structure 7 includes guiding wheels 701. A plurality of guiding wheels 701 are arranged inside the guiding block 504. The guiding wheels 701 are arranged adjacent to each other in pairs. The end of the consumable wire 502 sequentially passes through the space between adjacent guiding wheels 701. The ends of adjacent guiding wheels 701 are rotatably connected to shaft blocks 705. An eighth spring 706 is fixedly connected between the shaft blocks 705. Two pressing blocks 702 slide symmetrically in the middle of the guiding block 504. A seventh spring 703 is fixedly connected between the two pressing blocks 702. A blade 704 is fixedly connected to the bottom side of the pressing block 702. Positioning columns 707 are slidably connected to both sides of the guiding block 504. An eighth spring 706 is fixedly connected between the positioning columns 707 and the guiding block 504. The positioning column 707 has a "cross" structure. Annularly arranged fixing grooves 708 are formed inside the turntable 501. The positioning column 707 is engaged with the turntable 501 through the fixing groove 708;

[0046] Two guiding wheels 701 are arranged at both ends of the guiding block 504 for guiding the wire output. At the same time, under the traction of the eighth spring 706 between the shaft blocks 705 at the ends of the guiding wheels 701, the guiding wheels 701 can apply a certain clamping effect on the filament consumable in the middle. The guiding block 504 and the turntable 501 can rotate, thereby adjusting the wire output direction. Press the positioning columns 707 on both sides so that the side of the positioning column 707 disengages from the current fixing groove 708, and then the guiding block 504 can be rotated. After adjusting to the appropriate angle, release the positioning column 707 to fix it. On the other hand, a pressable pressing block 702 is arranged in the middle of the guiding block 504. After the filament consumable passes through the guiding block 504, the user can press the pressing block 702 to cut off the filament consumable through the inner blade 704, which is convenient for use.

[0047] Specifically, as Figure 1 , Figure 2 ,Figure 13 As shown, the cooling structure 6 includes a support frame 601. The support frame 601 is installed on the side of the printer body 1. An installation cross-column 604 is rotatably connected between the two support frames 601. A blower 602 is installed in the middle of the installation cross-column 604. One end of the installation cross-column 604 is fixedly connected to a worm gear sleeve 605. A control rod 603 is engaged with the side of the worm gear sleeve 605;

[0048] In order to cool the model in real time during printing and ensure the rapid cooling and curing of the material, a rotatable installation cross-column 604 is provided on the support frame 601 on the side of the printer body 1. The blower 602 in the middle of the installation cross-column 604 can perform air-cooling on the printed parts on the printer body 1. At the same time, the user can rotate the control rod 603 to rotate the installation cross-column 604 through the engaged worm gear sleeve 605, thereby adjusting the direction of the blower 602 and improving the cooling effect on printed parts of different heights.

[0049] When the present invention is in use, first, in order to ensure the horizontal placement of the printer body 1 in the placement area, support feet 205 with adjustable heights are respectively provided at the four corners of the bottom side of the printer body 1. The user can rotate the adjusting rod 201 corresponding to the support foot 205, drive the worm 204 of the connecting bevel gear 203 to rotate through the adjusting rod 201, and then drive the support foot 205 to move through the engagement groove 207, adjust the support height of the current position of the printer body 1, and ensure the overall horizontal placement of the printer body 1. Since the support height of the support foot 205 is adjusted by the adjusting rod 201, in order to facilitate the user to quickly reset the position of the support foot 205, the user can first press the adjusting cap 301 located on the side of the printer body 1, so that the square part at the end of the adjusting cap 301 is disengaged from the mating groove 303. At this time, the adjusting cap 301 can be rotated and drive the reset rod 302 to rotate. When the reset rod 302 rotates in any direction, the extended parts on both sides of the reset rod 302 will slide in the guiding grooves 306 on the corresponding traction plates 202, and at the same time traction the traction plates 202, so that the worm 204 at the other end of the traction plate 202 is disengaged from the engagement groove 207 on the support foot 205. After losing the support, the support foot 205 will be reset under the traction of the first spring 206. At this time, release the adjusting cap 301, and the traction plate 202 will drive the worm 204 to re-engage with the engagement groove 207 on the support foot 205 under the traction of the third spring 305. At the same time, the square part at the end of the adjusting cap 301 will slide back into the mating groove 303 again. At this time, since the adjusting cap 301 will limit the rotation of the reset rod 302 to fix the position of the traction plate 202, the effect of resetting and fixing the support foot 205 is achieved. At this time, the user can re-adjust the support foot 205. The mounting arm 401 located on the top side of the printer body 1 is used to place the consumables. The sliding seat 402 can slide into both ends of the side sliding groove 404 on the mounting arm 401. At the same time, a locking rod 405 with a triangular structure is provided at the bottom side of the sliding seat 402, which is convenient for adjusting and fixing the position of the sliding seat 402. In order to further improve the fixing effect of the position of the sliding seat 402 and ensure the stability of the device during the printing process, the user needs to keep pressing the locking rod 405 when sliding the sliding seat 402. At this time, the first abutment groove 409 and the second abutment groove 410 on the side of the locking rod 405 will respectively move to the positions of the second abutment rod 412 and the first abutment rod 407. Due to the existence of the abutment groove, the user can freely adjust the position of the sliding seat 402 on the mounting arm 401 at this time. After the adjustment is completed, release the locking rod 405. At this time, the abutment groove and the abutment rod are separated from each other, so that the first abutment rod 407 and the second abutment rod 412 will directly abut on the side of the locking rod 405, and the first abutment rod 407 and the second abutment rod 412 cannot slide, realizing the fixation of the position of the sliding seat 402 on the mounting arm 401. A turntable 501 is provided on the top side of the sliding seat 402.The middle part of the turntable 501 is used for placing the filament consumable. A guiding block 504 for guiding the filament consumable is arranged on the side of the turntable 501 to ensure smooth wire feeding of the print head at different heights. On the other hand, in order to facilitate the disassembly and assembly of the spool of the filament consumable, the mounting shaft 506 located in the middle of the turntable 501 is used to facilitate the rotation of the spool of the filament consumable. During installation, the user first needs to rotate the turntable 501 so that the second receiving groove 508 opened on the turntable 501 is rotated to align with the first receiving groove 507 on the sliding seat 402. At this time, the mounting shaft 506 can be directly taken out to install the spool of the filament consumable, which is convenient for operation. Both ends of the guiding block 504 for guiding the wire feeding are provided with two guiding wheels 701. At the same time, under the traction of the eighth spring 706 between the shaft blocks 705 at the ends of the guiding wheels 701, the guiding wheels 701 can exert a certain clamping effect on the filament consumable in the middle. The guiding block 504 can rotate relative to the turntable 501, thereby adjusting the wire feeding direction. Press the positioning posts 707 on both sides so that the sides of the positioning posts 707 are disengaged from the current fixing grooves 708, and then the guiding block 504 can be rotated.
