Description

Technical Field

[0001] This application relates to the field of 3D printing, and particularly to a waste cleaning device and a 3D printing device using the same. Background Art

[0002] 3D printing technology is a rapid prototyping technology that uses a digital model file as a basis and applies special wax materials, powdered metals, plastics, or other bondable materials to manufacture three-dimensional objects by printing layer upon layer of materials. Fused deposition modeling is one of the main 3D printing technologies. This technology melts a thermoplastic filament and extrudes it from a nozzle, depositing it on a forming platform or the previously solidified material of the previous layer to finally generate a physical object. Based on this, after certain types of print heads perform actions such as changing materials or stopping work, it is necessary to completely extrude the consumables in the nozzles of the print heads. How to handle the remaining materials extruded by the print heads and improve the overall efficiency of the 3D printing process is something that those skilled in the art need to consider.

The first direction X, the second direction Y, and the third direction Z are three non-parallel directions in a spatial coordinate system. In subsequent embodiments, taking the first direction X, the second direction Y, and the third direction Z as three mutually perpendicular reference directions in a three-dimensional Cartesian coordinate system as an example for description, the directions shown in the embodiments of the present application are used to help understand the relative positional relationship of each component, but do not limit its specific direction.

[0096] In one embodiment, the material receiving member 13 is fixedly connected to the bracket 11, and the contact portion 121 is movably connected to the bracket 11. The bracket 11 is provided with a receiving space 110, and the sliding portion 122 is slidably arranged in the receiving space 110. The bracket 11 is also provided with a through hole 1130.

[0097] In this embodiment, the bracket 11 includes a first connecting portion 111, a second connecting portion 112, and a third connecting portion 113.

The sliding portion 122 is also generally rod-shaped, and the second connection end 1222 and the third connection end 1223 are respectively located at two ends of the rod-shaped sliding portion 122 spaced apart along the first direction X.

[0104] In one embodiment, the contacting portion 121 includes a first portion 1213, a second portion 1214, and a third portion 1215. The second portion 1214 is disposed along the third direction Z between the first portion 1213 and the third portion 1215. The two ends of the second portion 1214 spaced apart along the third direction Z are respectively connected to the first portion 1213 and the third portion 1215.

[0105] In this embodiment, the first portion 1213 and the third portion 1215 are configured to be disposed substantially parallel to each other along the third direction Z, and the extending direction of the second portion 1214 connected between the first portion 1213 and the third portion 1215 intersects with the third direction Z. The included angle between the first portion 1213 and the second portion 1214 may be an obtuse angle, and the angle range is between 90° and 180°; the included angle between the second portion 1214 and the third portion 1215 may be an obtuse angle, and the angle range is between 90° and 180°.

[0106] It can be understood that the first portion 1213 is disposed closer to the sliding portion 122 than the third portion 1215, which can increase the stroke of the sliding portion 122 and the pusher 14 along the first direction X.

[0107] In this embodiment, the contact end 1212 may be convexly provided along the first direction X, and / or a flexible or arc-shaped contact surface is provided on the convex contact end 1212 to reduce the damage that may be caused by hard contact.

[0108] It can be understood that the sliding part 122 is guided by the third connecting part 113 along the first direction X, and the first connecting end 1211 is rotationally connected to the rotating shaft 124 through the second connecting end 1222, converting the rotation of the contact part 121 into a linear motion of the sliding part 122 along the first direction X.

[0109] In this embodiment, the third connecting end 1223 is spaced from the top end of the third connecting part 113 to define a moving gap. The third connecting end 1223 is connected to the pushing part 14, and the moving gap is used to provide space for the movement of the third connecting end 1223 along the first direction X.

[0110] In this embodiment, the rotating part 123 connects the plate wall of the second connecting part 112 and the contact part 121, enabling the contact part 121 to be rotationally connected to the second connecting part 112. The distance from the rotating part 123 to the contact end 1212 along the third direction Z is less than the distance from the rotating part 123 to the first connecting end 1211 along the third direction Z. Based on the lever principle, when the contact end 1212 moves a certain distance along the first direction X, it can drive the first connecting end 1211 to move a longer distance along the first direction X, improving the actuation efficiency.

[0111] It can be understood that the outer dimensions of the sliding part 122 are substantially equivalent to the inner dimensions of the accommodating space 110 provided in the third connecting part 113 along the second direction Y and the third direction Z, enabling the third connecting part 113 to guide the sliding part 122.

After being connected to the third connecting part 113, the receiving connecting part 132 extends along the second direction Y to the side of the third connecting part 113 away from the first connecting part 111. The receiving portion 131 is arranged along the second direction Y on the side of the third connecting part 113 away from the first connecting part 111 and is connected to the receiving connecting part 132.

[0114] In one embodiment, the receiving portion 131 includes a bottom plate 1311 and two side plates 1312. The two side plates 1312 are spaced along the second direction Y on both sides of the bottom plate 1311 to form the receiving cavity 130.

[0115] In this embodiment, the two side plates 1312 are arranged at intervals along the second direction Y. The bottom plate 1311 is arranged between the two side plates 1312 along the second direction Y and is connected to the side plates 1312 on the side away from the first connecting portion 111 or away from the through hole 1130 along the third direction Z, thereby forming a material receiving cavity 130 with a substantially "U"-shaped cross-section, so that the shape of the material receiving cavity 130 can be used to accommodate a certain volume of waste materials.

[0116] In this embodiment, both sides of the material receiving cavity 130 along the first direction X are configured to be through; in other embodiments, at least one side of the material receiving cavity 130 along the first direction X is configured to be through for discharging waste materials.

[0119] In one embodiment, the part of the pusher 14 arranged in the material receiving cavity 130 is located between the two side plates 1312 along the second direction Y, and the three side walls of the pusher 14 are configured to be in contact with exactly two side surfaces and one bottom surface to improve the efficiency of scraping waste materials.

[0120] In one embodiment, two spaced limiting plates 1431 are convexly arranged on the side of the pusher portion 143 away from the bottom plate 1311. The two limiting plates 1431 are arranged at intervals along the second direction Y, and the gap 1432 between the two limiting plates 1431 is configured to allow the nozzle of the nozzle 193 to pass through.

[0121] Further in combination with Figure 6 As shown, in another embodiment, the pusher 14 may further include a scraping portion 144, and the scraping portion 144 is integrally provided with or detachably connected to the pusher portion 143.

[0122] In this embodiment, a receiving groove 145 can be formed on the material pushing part 143 by processes such as stamping.

[0123] It can be understood that the material scraping part 144 can be used to scrape the remaining material at the nozzle. The material scraping part 144 is detachably connected to the material pushing part 143, and the height of the gap along the third direction Z can be adjusted by replacing the material scraping parts 144 with different sizes to adapt to different nozzles.

[0124] In one embodiment, the reset member 15 is arranged between the bracket 11 and the driving member 12, or different ends of the reset member 15 have a force acting relationship with the bracket 11 and the driving member 12 respectively, and the change in the distance between the driving member 12 and the bracket 11 can cause the mutual force between the reset member 15 and the bracket 11 and the driving member 12 to change.

[0125] Further combined with Figure 7 As shown, in one embodiment, one end of the reset member 15 is connected to the bracket 11, and the other end of the reset member 15 is connected to the contact part 121. The reset member 15 is arranged between the bracket 11 and the contact part 121 along the first direction X, and is used to drive the contact part 121, and the contact part 121 drives the sliding part 122 to move along the first direction X.

[0126] In this embodiment, taking the reset member 15 as a spring as an example for display, one end of the reset member 15 is connected to the inner wall of the second connecting part 112, and the other end of the reset member 15 is connected to the part of the contact part 121 between the contact end 1212 and the rotating part 123. The reset member 15 is configured to intersect with the contact part 121 approximately. The contact part 121 is driven to approach the second connecting part 112 along the first direction X and compress the reset member 15. When the external force driving the contact part 121 is withdrawn, the compressed reset member 15 has a tendency to expand, so as to push the contact part 121 to reset. The contact part 121 further drives the sliding part 122 to retreat, and the sliding part 122 drives the material pushing part 14 to reset.

[0127] It can be understood that in the figure, the end of the reset member 15 is taken as an example where it is a ring structure and is connected to the second connection portion 112 or the contact portion 121 for display; in other embodiments, a protruding columnar structure (not shown in the figure) may also be provided on the second connection portion 112 or the contact portion 121, and the columnar structure can extend into both ends of the reset member 15 to guide the reset member 15; or, a concave circular hole structure (not shown in the figure) may also be provided on the second connection portion 112 or the contact portion 121, and both ends of the reset member 15 can extend into the circular hole structure to guide the reset member 15; those skilled in the art can understand that these structures are all feasible.

[0128] Further in combination with Figure 8 As shown, in an embodiment, one end of the reset member 15 is connected to or detachably abuts against the bracket 11, and the other end of the reset member 15 is connected to or detachably abuts against the sliding portion 122. The reset member 15 is disposed between the bracket 11 and the sliding portion 122 along the first direction X and is used to drive the sliding portion 122 to move along the first direction X.

[0129] In this embodiment, taking the reset member 15 as a spring for display, one end of the reset member 15 abuts against the inner wall of the third connection portion 113, and the other end of the reset member 15 abuts against the end face of the sliding portion 122 away from the contact portion 121. The extending direction of the reset member 15 is configured to be substantially the same as the sliding direction of the sliding portion 122. The contact portion 121 is driven to drive the sliding portion 122 to move along the first direction X and compress the reset member 15. When the external force driving the contact portion 121 is withdrawn, the compressed reset member 15 has a tendency to expand, thereby pushing the sliding portion 122 to retreat, and the sliding portion 122 drives the pusher 14 to reset.

[0130] It can be understood that a protruding columnar structure or a concave circular hole structure (not shown in the figure) may be provided on the third connection portion 113 and the sliding portion 122, and the protruding columnar structure or the concave circular hole structure can be arranged along the first direction X and is used to cooperate with the reset member 15 to guide it, so as to improve the reset efficiency and reset accuracy.

[0131] It can be understood that in other embodiments, the reset member 15 can also be other elastic structures such as a torsion spring, an elastic rod, etc.; or, the reset member 15 can also be other types of reset structures, such as a structure that is reset by other non-contact forces such as magnetism.

[0132] In one embodiment, the working process of the waste cleaning device 10 of the present application can be roughly as follows: The contact end 1212 is driven by an external force (for example, being extruded by the nozzle 193 of the 3D printing device 1 along the first direction X) and moves along the first direction X away from the material receiving member 13. The contact portion 121 drives the reset member 15 to move and / or deform, thereby accumulating force. The contact portion 121 rotates about the rotating portion 123, and the first connection end 1211 moves along the first direction X toward the material receiving member 13. The second connection end 1222 is driven by the first connection end 1211, and the sliding portion 122 slides along the first direction X in the third connection portion 113. The third connection end 1223 drives the pusher 14 to move along the first direction X away from the second connection portion 112. The pushing portion 143 of the pusher 14 is driven to move from one end of the material receiving cavity 130 to the other end along the first direction X. The material receiving cavity 130 is open on the side close to the second connection portion 112 along the first direction X, and the side of the material receiving cavity 130 away from the second connection portion 112 along the first direction X is blocked by the pushing portion 143. The material receiving member 13 and the pusher 14 cooperate to receive and accommodate the remaining material. After the material discharging is completed, the external force applied to the contact end 1212 is removed (for example, the nozzle 193 of the 3D printing device 1 has been or is being separated from the waste cleaning device 10). The driving member 12 is driven by the reset member 15 to reset, the contact portion 121 rotates back to its original position, the sliding portion 122 moves along the first direction X toward the second connection portion 112, and the sliding portion 122 drives the pusher 14 to move along the first direction X toward the second connection portion 112 in the material receiving cavity 130. The pusher 14 scrapes the remaining material in the material receiving cavity 130 out of the material receiving cavity 130.

[0133] Further in combination with Figure 9 As shown, the embodiment of the present application further provides a 3D printing device 1, which includes a 3D printing main body 19 and a waste cleaning device 10. The waste cleaning device 10 is connected to the 3D printing main body 19.
