[0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis and uses powdered metal or plastic and other adhesive materials to construct objects by printing layer by layer. 3D printing is usually achieved using digital technology material printers. It is often used to make models in mold manufacturing, industrial design and other fields, and then gradually used for the direct manufacturing of some products. There are already parts printed using this technology.
[0003] During the printing process of the 3D printing head in the prior art, for some larger products, the position of the 3D printing head cannot be adjusted, and the product itself can only be moved, which sometimes easily causes certain damage to the product.

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. The present invention provides a fixed column, a rotating column and a handle, and the handle can be lifted by hand, the handle drives the fixed plate and the rotating column to move upward, the rotating column drives the card plate to move out from between the two card blocks, and the bottom end of the rotating column is located at the top of a plurality of card blocks. At this time, the handle can be rotated to rotate the fixed plate in the rotating through hole with the rotating column as the rotating axis, and the print head can be rotated to a certain angle, so that the print head can adjust the angle.

[0026] In addition, in the description of the present invention, “several” means two or more than two, unless otherwise clearly and specifically defined.
[0027] See also Figure 1-4 , the present invention provides a technical solution:
[0028] A 3D printing head support adjustable device, including a base 1, a fixed column 2 is provided on the top surface of the base 1, a rotating through hole 21 is provided on the top of the fixed column 2, a limiting groove 22 is provided on the bottom surface of the rotating through hole 21, a plurality of clips 23 arranged in an annular shape and at equal intervals are provided on the inner wall of the limiting groove 22 and at the bottom surface, a rotating column 3 is provided between the plurality of clips 23, a clip plate 31 is provided on the circumferential wall of the rotating column 3, the clip plate 31 is located between any two clips 23, the upper end of the rotating column 3 passes through the limiting groove 22 and the rotating through hole 21 and extends to the outside, a fixed plate 4 is provided on the top of the rotating column 3, and a handle is provided on the top of the fixed plate 4 Hand 5, and the handle 5 is located just above the rotating column 3. Rotating the handle 5 can make the fixed plate 4 rotate with the handle 5 and the rotating column 3 as the axis; a rectangular groove 41 is provided in the fixed plate 4, and slide grooves 42 are provided on the left and right sides of the rectangular groove 41; a movable plate 6 is provided in the rectangular groove 41, and one end of the movable plate 6 passes through the rectangular groove 41 and extends to the outside, and rubber blocks 61 are provided on the left and right sides of one end of the movable plate 6, and the rubber block 61 is located in the slide groove 42, and cylinders 62 are provided on the left and right sides of the other end of the movable plate 6, and a through hole 63 is provided at the end of the movable plate 6 away from the fixed plate 4, and a print head 7 is provided in the through hole 63.
[0029] Specifically, the base 1, the fixing column 2 and the clamp 23 are integrally formed to ensure that the structures of the fixing column 2 and the clamp 23 are stable.
[0030] Furthermore, the height of the card fastener 23 is equal to the height of the card plate 31 , and the height of the limiting groove 22 is twice the height of the card fastener 23 , ensuring that when the card plate 31 moves up to the top of the card fastener 23 , the card plate 31 can rotate with the rotating column 3 in the limiting groove 22 .
[0031] Specifically, the clamping plate 31 and the rotating column 3 are an integrally formed structure, the rotating column 3 is tightly bonded to the fixed plate 4, and the fixed plate 4 is tightly bonded to the handle 5, to ensure the stability of the overall structure. When the print head 7 needs to be rotated to a certain angle, the handle 5 can be rotated by hand to enable the fixed plate 4 to rotate in the rotating through hole 21 with the rotating column 3 as the axis, thereby changing the angle of the print head 7.
[0032] Furthermore, the card plate 31 is plugged into and matched with any two card fasteners 23. When the card plate 31 is inserted into any two card fasteners 23, it can limit the rotation of the rotating column 3 in the limit groove 22 and the rotating through hole 21; the rotating column 3 is rotatably connected to the limit groove 22 and the rotating through hole 21 respectively, ensuring that the rotating column 3 can rotate in the limit groove 22 and the rotating through hole 21.
[0033] Specifically, the diameter of the rotating column 3 is equal to the diameter of the rotating through hole 21 , and the diameter of the limiting groove 22 is larger than the diameter of the rotating through hole 21 . The restriction of the clamping plate 31 can prevent the rotating column 3 from escaping from the rotating through hole 21 .
[0034] Furthermore, the movable plate 6 is slidably connected to the rectangular groove 41 to ensure that the movable plate 6 can move in the rectangular groove 41 , and the rubber block 61 is slidably connected to the slide groove 42 to ensure that the rubber block 61 can move in the slide groove 42 .
[0035] Specifically, the movable plate 6, the rubber block 61 and the cylinder 62 are an integrally formed structure to ensure the stability of the structure. The length of the movable plate 6 is greater than the length of the rectangular groove 41. When one end of the movable plate 6 is in contact with one end inside the rectangular groove 41, the print head 7 is in contact with one end of the fixed plate 4 to ensure that the print head 7 will not be damaged.
[0036] Furthermore, the print head 7 is movably connected to the through hole 63 , and when the movable plate 6 and the fixed plate 4 rotate with the rotating column 3 as the rotating axis, the print head 7 moves in the through hole 63 to change the printing position of the print head 7 .
[0037] It is worth noting that the rubber block 61 has a certain elasticity and a large friction force. When the movable plate 6 moves in the rectangular groove 41, a large force is required to pull or push the cylinder 62 to move, so that the rubber block 61 moves in the slide groove 42, ensuring the stability of the structure of the movable plate 6 in the rectangular groove 41 and the stability of the structure of the print head 7. When one end of the rubber block 61 is in contact with the end of the slide groove 42 away from the rotating column 3, in the vertical direction, the print head 7 is located in the base 1, preventing the print head 7 from printing the product and causing the product to fall from the base 1.
[0038] When the adjustable 3D print head support device of this embodiment is in use, the print head 7 can perform the following operations during the printing process according to the size of the product and the angle to be rotated: determine the angle that the print head 7 needs to rotate for printing; hold the handle 5 and lift it up, the handle 5 drives the fixed plate 4 and the rotating column 3 to move up, the rotating column 3 drives the card plate 31 to move to the top of the plurality of card blocks 23, and the bottom end of the rotating column 3 also moves up and is located at the top of the plurality of card blocks 23. At this time, the handle 5 can be rotated to rotate, so that the fixed plate 4 can rotate in the rotating through hole 21 with the rotating column 3 as the rotating axis, the card plate 31 rotates in the limiting groove 22 with the rotating column 3, and the movable plate 6 and the print head 7 rotate with the fixed plate 4 to a determined angle; then, determine the distance that the print head 7 moves, pull or push the cylinder 62 with a greater force, so that the movable plate 6 moves in the rectangular groove 41, the rubber block 61 moves in the slide groove 42, and the print head 7 moves in the through hole 63 with the movable plate 6, so that the position of the print head 7 on the horizontal plane moves to a determined position, and then printing is performed.
