Description

Technical Field

[0001] This invention relates to the field of additive manufacturing equipment technology, specifically to an additive manufacturing equipment for processing automotive plastic parts. Background Technology

[0002] Additive manufacturing is a technology that uses a gradual accumulation of material to create solid parts. Compared to traditional material removal and machining techniques, it is a "bottom-up" manufacturing method. The 3D printing technology we are familiar with is an example of additive manufacturing. Existing additive manufacturing equipment, or 3D printing equipment, typically uses a three-axis movement method, heating and melting filaments to achieve layer-by-layer printing, ultimately producing the designed 3D object.

[0003] However, to ensure the effectiveness of 3D printing equipment, it is necessary to ensure that the device is placed horizontally. However, existing 3D printing equipment is usually not convenient for adjusting the level for different placement areas, which may affect the subsequent leveling of the printed surface. At the same time, in order to make the finished product have different colors, different colored filaments are used during the printing process. The existing equipment is inconvenient to add filaments and it is not convenient to adjust the placement position as needed. Furthermore, filaments usually have a certain degree of hardness and toughness, which may cause the filaments on the winch to shift or even detach when the print head is raised, affecting the addition of filaments.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figure 1 , Figure 3 , Figure 5 , Figure 7 As shown, the additive manufacturing equipment for processing automotive plastic parts according to the present invention includes a printer body 1, a leveling structure 2 on the bottom side of the printer body 1, a reset structure 3 on the inner side of the printer body 1, a mounting structure 4 on the top side of the printer body 1, a locking structure 5 connected to the mounting structure 4, a guide structure 7 connected to the locking structure 5, and a cooling structure 6 connected to the side of the printer body 1.

[0037] Specifically, such as Figure 1 , Figure 3 , Figure 7As shown, the leveling structure 2 includes support feet 205. Multiple 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. A meshing groove 207 is provided on the side of the support foot 205. A traction plate 202 is provided on the side of the support foot 205. A worm gear 204 is rotatably connected to the end of the traction plate 202. The side of the worm gear 204 meshes with the support foot 205 through the meshing groove 207. There are four support feet 205, which are arranged in a square on the bottom side of the printer body 1. A bevel gear 203 is fixedly connected to the top of the worm gear 204. An adjusting rod 201 meshes with the side of the bevel gear 203. The middle part of the adjusting rod 201 is rotatably connected to the side of the printer body 1.

[0038] The user can rotate the adjustment rod 201 of the corresponding support foot 205, which drives the worm gear 204 connected to the bevel gear 203 to rotate, and then drives the support foot 205 to move through the meshing groove 207, thereby adjusting the support height of the printer body 1 at the current position and ensuring that the printer body 1 is placed horizontally.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, the reset structure 3 includes a guide groove 306. The end of the traction plate 202 is provided with the guide groove 306. The traction plate 202 is slidably connected to the printer body 1. A third spring 305 is fixedly connected between the side 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 adjustment cap 301 is slidably connected to the end of the reset rod 302. A second spring 304 is fixedly connected between the adjustment cap 301 and the printer body 1. The end of the adjustment cap 301 has a square structure. A mating groove 303 is provided on the inner side of the printer body 1. The square end of the adjustment cap 301 is slidably connected to the printer body 1 through the mating groove 303.

[0040] 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 disengages from the mating groove 303. At this time, the adjusting cap 301 can rotate 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 guide groove 306 on the corresponding traction plate 202, and at the same time pull the traction plate 202, so that the worm gear 2 at the other end of the traction plate 202... 04. After disengaging from the engagement groove 207 on the support foot 205 and losing support, the support foot 205 will reset under the traction of the first spring 206. At this time, the adjusting cap 301 is released, and the worm gear 204 re-engages 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. Since the adjusting cap 301 restricts the rotation of the reset rod 302, the position of the traction plate 202 is fixed, thus achieving the effect of resetting and fixing the support foot 205. At this time, the user can readjust the support foot 205.

[0041] Specifically, such as Figure 1 , Figure 4 , Figure 8 , Figure 9 As shown, the mounting structure 4 includes a mounting arm 401, which is fixedly connected to the top of the printer body 1. The mounting arm 401 has side sliding grooves 404 in a U-shape on both sides. A sliding seat 402 is slidably connected to the mounting arm 401 via the side sliding grooves 404. A first abutment rod 407 is slidably connected to the middle of the sliding seat 402. The end of the first abutment rod 407 has a triangular structure. A fifth spring 408 is fixedly connected between the first abutment rod 407 and the sliding seat 402. A toothed groove 403 is provided on the top side of the mounting arm 401, and the first abutment rod 407 abuts against the mounting arm 401 through the toothed groove 403. A second abutment rod 412 is slidably connected to each side of the sliding seat 402. A sixth spring 411 is fixedly connected between the second abutment 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 abutment rod 407, the second abutment rod 412 and the locking rod 405 are all hemispherical ends. A first abutment groove 409 is opened on each side of the locking rod 405. A second abutment groove 410 is opened on the bottom side of the locking rod 405. The hemispherical ends of the first abutment rod 407 and the second abutment rod 412 abut against the side of the locking rod 405.

[0042] The mounting arm 401 located on the top side of the printer body 1 is used to hold consumables. The sliding seat 402 can slide into the mounting arm 401 through both ends of the side sliding groove 404. At the same time, the bottom side of the sliding seat 402 is provided with a triangular locking rod 405 to facilitate the adjustment and fixation of the position of the sliding seat 402. In order to further improve the fixation 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 abutment groove 409 on the side of the locking rod 405 and the second abutment groove 405 are engaged. The two abutment grooves 410 will move to the positions of the second abutment rod 412 and the first abutment rod 407 respectively. Due to the presence of the abutment grooves, the user can freely adjust the position of the sliding seat 402 on the mounting arm 401. After adjustment, the locking rod 405 is released. At this time, the abutment grooves and abutment rods are separated from each other, so that the first abutment rod 407 and the second abutment rod 412 will directly abut against the side of the locking rod 405, and the first abutment rod 407 and the second abutment 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 engaging 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 an installation shaft 506. Both ends of the installation shaft 506 are provided with protruding structures. Both sides of the sliding seat 402 are provided with first receiving grooves 507. The installation shaft 506 is slidably connected to the sliding seat 402 through the first receiving grooves 507. The protrusions at both ends of the installation shaft 506 abut against 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 multiple positioning grooves 505. The turntable 501 abuts against the second abutting rod 412 on the same side through the positioning grooves 505. A wire roll 503 is rotatably connected to the installation shaft 506. Consumable wire 502 is fixedly connected to the side of the wire roll 503. A guide block 504 is rotatably connected to the side of the turntable 501.

[0044] The center of the turntable 501 is used to place filament consumables. A guide block 504 is provided on the side of the turntable 501 to guide the filament consumables, ensuring smooth filament feeding at different printhead heights. On the other hand, to facilitate the installation and removal of the filament consumable reel, the mounting shaft 506 located in the center of the turntable 501 is used to facilitate the rotation of the filament consumable reel. During installation, the user first needs to rotate the turntable 501 so that the second receiving groove 508 on the turntable 501 and the first receiving groove 507 on the sliding seat 402 are aligned. At this point, the mounting shaft 506 can be directly removed to install the filament consumable reel, which is convenient for operation.

[0045] Specifically, such as Figure 5 , Figure 10 , Figure 11 , Figure 12 As shown, the guide structure 7 includes guide wheels 701. Multiple guide wheels 701 are provided on the inner side of the guide block 504. The guide wheels 701 are arranged adjacent to each other in pairs. The end of the consumable filament 502 passes sequentially between adjacent guide wheels 701. A shaft block 705 is rotatably connected to the end of adjacent guide wheels 701. An eighth spring 706 is fixedly connected between the shaft blocks 705. Two pressing blocks 702 slide symmetrically in the middle of the guide block 504. A seventh spring 703 is fixedly connected between blocks 702. A blade 704 is fixedly connected to the bottom side of the pressing block 702. Positioning posts 707 are slidably connected to both sides of the guide block 504. An eighth spring 706 is fixedly connected between the positioning posts 707 and the guide block 504. The positioning posts 707 have a "+" shaped structure. The inner side of the turntable 501 is provided with a ring of fixed grooves 708. The positioning posts 707 are engaged with the turntable 501 through the fixed grooves 708.

[0046] The guide block 504, used to guide the filament output, has two guide wheels 701 at both ends. The guide wheels 701 are pulled by an eighth spring 706 between the end shaft blocks 705, allowing them to clamp the filament in the middle. The guide block 504 can rotate with the turntable 501, thus adjusting the direction of the filament output. Pressing the positioning pins 707 on both sides disengages the sides of the positioning pins 707 from the current fixing groove 708, allowing the guide block 504 to rotate. After adjusting to a suitable angle, releasing the positioning pins 707 secures the filament. Furthermore, a pressable block 702 is located in the middle of the guide block 504. After the filament passes through the guide block 504, the user can press the press block 702 to cut the filament using the inner blade 704, facilitating use.

[0047] Specifically, such as Figure 1 , Figure 2 , Figure 13 As shown, the cooling structure 6 includes a support frame 601. The support frame 601 is mounted on the side of the printer body 1. A mounting column 604 is rotatably connected between the two sides of the support frame 601. A fan 602 is mounted in the middle of the mounting column 604. A worm gear sleeve 605 is fixedly connected to one end of the mounting column 604. A control rod 603 is engaged on the side of the worm gear sleeve 605.

[0048] In order to cool the model in real time during the printing process and ensure the rapid cooling and curing of the material, a rotatable mounting column 604 is provided on the support frame 601 located on the side of the printer body 1. The fan 602 in the middle of the mounting column 604 can cool the printed parts on the printer body 1. At the same time, the user can rotate the control lever 603, which rotates the mounting column 604 through the meshing worm gear sleeve 605, thereby adjusting the direction of the fan 602 and improving the cooling effect on printed parts of different heights.

[0049] In use, to ensure the printer body 1 is placed horizontally in the designated area, each of the four corners of the bottom side of the printer body 1 is equipped with an adjustable support foot 205. The user can rotate the adjustment rod 201 corresponding to the support foot 205. The adjustment rod 201 drives the worm gear 204 connected to the bevel gear 203 to rotate, which in turn drives the support foot 205 to move through the meshing groove 207, adjusting the support height of the printer body 1 at its current position and ensuring the overall horizontal placement of the printer body 1. Since the support height of the support foot 205 is adjusted by the adjustment rod 201, to facilitate quick repositioning of the support foot 205, the user can first press the adjustment cap 3 located on the side of the printer body 1. 01, causing the square portion at the end of the adjusting cap 301 to disengage from the mating groove 303. At this time, the adjusting cap 301 can rotate and drive the reset rod 302 to rotate. When the reset rod 302 rotates in any direction, the extended portions on both sides of the reset rod 302 will slide in the guide groove 306 on the corresponding traction plate 202, and at the same time pull the traction plate 202, causing the worm 204 at the other end of the traction plate 202 to disengage from the meshing groove 207 on the support foot 205. After losing support, the support foot 205 will reset under the traction of the first spring 206. At this time, the adjusting cap 301 is released, and the worm 204 of the traction plate 202 re-engages with the meshing groove 207 on the support foot 205 under the traction of the third spring 305. At the same time, the adjusting cap 301... The square portion at the end will slide back into the mating groove 303. At this time, the adjusting cap 301 will restrict the rotation of the reset rod 302, thereby fixing the position of the traction plate 202, achieving the effect of resetting and fixing the support foot 205. At this time, the user can readjust the support foot 205. 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 into the two ends of the side sliding groove 404 on the mounting arm 401. At the same time, the bottom side of the sliding seat 402 is provided with a triangular locking rod 405 to facilitate the adjustment and fixing of 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 printing, the user slides the sliding seat. At position 402, the locking lever 405 needs to be pressed. At this time, the first abutment groove 409 and the second abutment groove 410 on the side of the locking lever 405 will move to the positions of the second abutment rod 412 and the first abutment rod 407, respectively. Due to the presence of the abutment grooves, the user can freely adjust the position of the sliding seat 402 on the mounting arm 401. After adjustment, release the locking lever 405. At this time, the abutment grooves and abutment rods separate, causing the first abutment rod 407 and the second abutment rod 412 to directly abut against the side of the locking lever 405, and preventing them from sliding. This fixes the position of the sliding seat 402 on the mounting arm 401. A turntable 501 is located on the top side of the sliding seat 402.The center of the turntable 501 is used to hold filament consumables. A guide block 504 is provided on the side of the turntable 501 to guide the filament consumables, ensuring smooth filament feeding at different printhead heights. Furthermore, to facilitate the installation and removal of the filament consumable reel, a mounting shaft 506 located in the center of the turntable 501 allows for easy rotation of the filament consumable reel. During installation, the user first needs to rotate the turntable 501 so that the second receiving groove 508 on the turntable 501 engages with the sliding seat. When the first receiving groove 507 on 402 is rotated to be aligned, the mounting shaft 506 can be directly removed for installation of the filament consumable reel, facilitating operation. The guide block 504, used to guide the filament output, has two guide wheels 701 at both ends. Simultaneously, the guide wheels 701 are pulled by the eighth spring 706 between the shaft blocks 705 at the ends of the guide wheels 701, allowing the guide wheels 701 to apply a certain clamping effect to the filament consumable in the middle. The guide block 504 and the turntable 501 can rotate, thereby adjusting... To adjust the direction of the filament output, press the positioning pins 707 located on both sides to disengage the sides of the positioning pins 707 from the current fixing slots 708, allowing the guide block 504 to rotate. After adjusting to the appropriate angle, release the positioning pins 707 to fix them in place. On the other hand, a pressable pressing block 702 is located in the middle of the guide block 504. After the filament passes through the guide block 504, the user can press the pressing block 702 to cut the filament through the inner blade 704 for easy use.
