Description

Technical Field

[0001] The present invention relates to the technical field of 3D printing, and particularly to an extrusion device for printing wire used in the production of automotive trim parts. Background Art

[0002] 3D printing is a technology that constructs objects by layer-by-layer printing based on digital model files, using powdered metals or plastics and other bondable materials. In recent years, 3D printing technology has been widely used in industries such as healthcare, construction, and industrial manufacturing. When producing automotive trim parts, 3D printing technology is also often used.

[0003] There is a conventional 3D printer three-color wire extrusion machine device and control method, with the patent publication number CN110406105A. The floor area of its extrusion box is smaller than that occupied by three single-line extruders, reducing the excessive area occupied by the extruder on the 3D printer, thereby reducing the working load of the 3D printer and facilitating the operation of the 3D printer. There is also a wire extrusion device for 3D printers, with the patent publication number CN109927295A. Through the setting of a feeding mechanism, which is set as at least one set of pulley units, and the gap in the pulley unit is part of the wire channel, it is possible to effectively straighten the bent wire through the guidance of the pulley unit. Further, by using a roller with multiple brushes on its inner wall, the wire can be cleaned by the brushes, effectively improving its cleanliness. And the roller is set to be able to rotate, further improving the cleaning effect. On this basis, a preheating and heating unit are sequentially arranged outside the melt cylinder to effectively preheat the wire, avoiding problems such as excessive temperature difference at the connection between the heated section and the unheated part during heating, and thus effectively ensuring the quality of 3D printed products.

Then the spool 4 can be moved, driving the clamping block 16 on the fixing ring 15 to disengage from the clamping groove, so as to remove the spool 4 for replacement. The purpose of setting two spools 4 is to timely supply the printing wire to avoid jamming.

[0038] Refer to Figures 1 to 15, there are two wire sleeves 6. The wire sleeves 6 are sleeved on one end of the printing wire body 5, and the wire sleeves 6 are arranged inside the housing.

Pass one end of the printing wire body 5 through the wire sleeve 6. The output end of the electric push rod 28 drives the turntable 26 to slide on the sliding rail 25, drives the two rotating plates 24 to rotate. The rotation of the rotating plate 24 drives the rotating seat 23 and the sliding rod 21 to move. The two sliding rods 21 drive the two clamping plates 22 to move towards each other, so as to fix the printing wire body 5. The housing 1 is provided with a displacement driving component for driving the wire sleeve 6 to move. The displacement driving component includes fixing plates 29, rotating screws 30, threaded plates 31 and a first motor 32. There are two fixing plates 29, and the two fixing plates 29 are both fixedly connected to the housing 1. The rotating screw 30 is rotatably connected between the two fixing plates 29. The threaded plate 31 is threadedly sleeved on the rotating screw 30, and the threaded plate 31 is slidably connected to the housing 1. The threaded plate 31 is fixedly connected to the wire sleeve 6. The first motor 32 is fixedly installed on the fixing plate 29. The output end of the first motor 32 penetrates through the fixing plate 29 and is concentrically connected to the rotating screw 30. The output end of the first motor 32 drives the rotating screw 30 to rotate. The rotation of the rotating screw 30 drives the threaded plate 31 to slide. The threaded plate 31 drives the wire sleeve 6 to move, so as to drive the printing wire body 5 to the middle of the two driving rollers 10. A detection sensor 7 is fixedly installed on the housing 1. The detection sensor 7 is used to detect whether there is still the printing wire body 5 directly in front. When it is detected that there is no printing wire body 5 directly in front, the two first motors 32 are automatically started through the single-chip microcomputer controller, driving the wire sleeve 6 located directly above the two driving rollers 10 to deviate from the center and move, and the other wire sleeve 6 moves towards the center. Because when fixing one end of the printing wire body 5, one end of the printing wire body 5 will be slightly passed through one end of the wire sleeve 6 for a certain distance, so automatic replenishment and feeding can be carried out, and there will be no jamming phenomenon.The opening door 8 is hinged to the housing 1, and a fixed lock is provided between the opening door 8 and the housing 1 for limiting the opening door 8 to the housing 1.

[0039] Refer to Figures 1 to 15 As shown, there are multiple rotating shafts 9. The multiple rotating shafts 9 are all rotatably connected to the housing 1, and a driving roller 10 is fixedly sleeved on the rotating shaft 9. A linkage assembly is provided between the multiple rotating shafts 9 for driving the driving rollers 10 on both sides to rotate in opposite directions. The linkage assembly includes rotating gears 33, mounting frames 34, rotating rods 35, linkage gears 36, and a second motor 37. There are multiple rotating gears 33, and the multiple rotating gears 33 are respectively fixedly sleeved on the multiple rotating shafts 9, and two adjacent rotating gears 33 are meshed with each other. There are multiple mounting frames 34, and the multiple mounting frames 34 are all fixedly connected to the housing 1.

The second motor 37 is fixedly installed on the housing 1, and the output end of the second motor 37 penetrates the housing 1 and is concentrically connected to one of the rotating shafts 9. The output end of the second motor 37 drives the rotating shaft 9 on its side to rotate. This rotating shaft 9 drives the rotating gear 33 on its side to rotate. This rotating gear 33 drives the adjacent rotating gear 33 to rotate in the opposite direction. Then, through the drive of the linkage gear 36, the rotating gears 33 on the same side can be driven to rotate in the same direction, and two adjacent rotating gears 33 rotate in the opposite direction, thereby driving the driving roller 10 to rotate. The driving roller 10 drives the printing wire body 5 to move, and at the same time, the driving roller 10 can straighten the printing wire body 5. The rotating gears 33 and the linkage gears 36 in the figures of this application are schematic diagrams. In actual research and development, for safety considerations during the manufacturing process, the number of teeth of the rotating gears 33 and the linkage gears 36 is not less than 17.

[0040] Refer to Figures 1 to 15, the cleaning component is arranged on the outer shell 1 and is used to clean the impurities on the printing wire body 5. The cleaning component includes a suction fan 38, a suction pipe 39, an impurity box 40, a cleaning door 41, a dust-proof net 42, a suction pipe 43 and a cleaning sleeve 44. The suction fan 38 is fixedly installed on the outer shell 1, the suction pipe 39 is connected to the suction fan 38, the impurity box 40 is fixedly connected to the outer shell 1, and the impurity box 40 is connected to the suction pipe 39.

The dust-proof net 42 is fixedly connected to the suction pipe 39, and the dust-proof net 42 prevents impurities from entering the suction fan 38. The suction pipe 43 is connected to the impurity box 40, and the cleaning sleeve 44 is connected to the suction pipe 43. When the printing wire body 5 passes through the cleaning sleeve 44, the suction fan 38 sucks air through the suction pipe 39, and the impurities on the surface of the printing wire body 5 will enter the impurity box 40 through the suction pipe 43, which is convenient for cleaning the printing wire body 5 to prevent impurities from affecting the quality of 3D printing. An air flow sensor 45 is fixedly installed on the impurity box 40, and the air flow sensor 45 is arranged above the dust-proof net 42. The air flow sensor 45 is convenient for detecting the air flow velocity at the dust-proof net 42 in the impurity box 40.

The spray pipe 12 passes through the outer shell 1 and extends to the outside, and a one-way valve 13 is arranged on the spray pipe 12. A nozzle 14 is arranged on the spray pipe 12. When the printing wire body 5 enters the heating pipe 46, the heating wire 47 heats and melts the printing wire body 5, and the melted raw material enters the material cylinder 11 through the discharge hopper 49. When the one-way valve 13 is opened, the raw material will be ejected from the nozzle 14 on the spray pipe 12, thereby performing 3D printing. Two detection probes 50 are fixedly connected to the inner side wall of the outer shell 1, and two warning lights 51 matching the detection probes 50 are fixedly installed on the outer side wall of the outer shell 1. The detection probes 50 detect whether the printing wire body 5 on their own side exists. When the printing wire body 5 is gone, the warning light 51 on the same side is turned on through the single-chip microcomputer controller to remind the staff to replace the spool 4.

[0041] Embodiment 2

[0042] In summary, the working principle and process of the printing wire extrusion device for automotive trim production are as follows. When in use, first, respectively set the two wire reels 4 on the two central shafts 3. Pull the pull ring 20 outwards. The pull ring 20 drives the moving plate 18 to move. The moving plate 18 drives the clamping rod 19 to move. The telescopic spring 17 elastically expands and contracts. Align the clamping block 16 on the fixed ring 15 with the card slot and press it in. Release the pull ring 20. The telescopic spring 17 elastically contracts, driving the clamping rod 19 into the card slot. Then, pass one end of the printing wire body 5 through the wire sleeve 6. The output end of the electric push rod 28 drives the turntable 26 to slide on the slide rail 25, driving the two rotating plates 24 to rotate. The rotation of the rotating plate 24 drives the rotating seat 23 and the sliding rod 21 to move. The two sliding rods 21 drive the two clamping plates 22 to move towards each other to clamp the printing wire body 5. Then, just close the opening door 8;

[0043] Drive the two clamping plates 22 to move away from each other through the electric push rod 28. The output end of the second motor 37 drives the rotating shaft 9 on its side to rotate. The rotating shaft 9 drives the rotating gear 33 on its side to rotate. The rotating gear 33 drives the adjacent rotating gear 33 to rotate in the opposite direction. Then, through the drive of the linkage gear 36, the rotating gear 33 on the same side can be driven to rotate in the same direction. The adjacent two rotating gears 33 rotate in the opposite direction, thereby driving the driving roller 10 to rotate. The driving roller 10 drives the printing wire body 5 to move. The printing wire body 5 enters the cleaning sleeve 44. The suction fan 38 sucks air through the suction pipe 39. The impurities on the surface of the printing wire body 5 will enter the impurity box 40 through the dust suction pipe 43. Then, when the printing wire body 5 enters the heating pipe 46, the printing wire body 5 is heated and melted by the heating wire 47. The melted raw material enters the material cylinder 11 through the discharge hopper 49. Open the one-way valve 13, and the raw material will be sprayed out through the nozzle 14 on the spray pipe 12, thus performing 3D printing;

[0044] When it is detected that there is no printing wire body 5 directly in front, the single-chip microcomputer controller automatically turns on the two first motors 32. The output end of the first motor 32 drives the rotating screw 30 to rotate. The rotation of the rotating screw 30 drives the threaded plate 31 to slide. The threaded plate 31 drives the wire sleeve 6 to move, thereby driving the wire sleeve 6 directly above the two driving rollers 10 to deviate from the center and move. The other wire sleeve 6 moves towards the center. When the printing wire body 5 runs out, the single-chip microcomputer controller turns on the warning light 51 on the same side.

[0045] The above-described embodiments merely represent specific implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
