Description

Technical Field

[0001] The utility model belongs to the technical field of 3D tire printing, and relates to a 3D printing device with an auxiliary blanking structure. Background Art

[0002] A 3D printing device, also known as an additive manufacturing device, constructs three-dimensional solid objects by stacking materials layer by layer. Different from traditional subtractive manufacturing (such as turning, milling, etc.), 3D printing does not require complex tools or molds and can directly generate complex geometric shapes from digital model files (such as STL files), which greatly simplifies the design and manufacturing process. When a 3D printing device prints products, if it lacks an auxiliary blanking structure, it may face a series of problems.

[0003] The absence of an auxiliary blanking structure may also affect the usability and user experience of the 3D printer. When users use the 3D printer, they cannot move the carrier plate carrying the 3D tire model back and forth and adjust the blanking space. Equipment lacking an auxiliary blanking structure may require frequent user intervention, increasing the damage to the 3D tire model. Therefore, there is an urgent need for a 3D printing device with an auxiliary blanking structure to solve the above problems. Summary of the Invention

The two sets of transverse guide columns 160 and the transverse lead screw 140 are horizontally arranged, and the horizontal movement of the moving seat 150 can be maintained by using the transverse guide columns 160.

[0026] On the upper ends of the two sets of transverse guide columns 160 and the transverse lead screw 140, a moving seat 150 for carrying the print head 200 is provided. A ball screw seat 13c for movably connecting with the transverse lead screw 140 is provided at the middle position of the moving seat 150.

[0027] Inside the lower end of the support 110, a printing cavity for performing 3D printing operations is provided. At the lower end of the printing cavity, a carrier plate 170 for carrying the 3D tire model is provided. On the left and right sides at the lower end of the carrier plate 170, a set of lower lead screw groups 180 for driving the carrier plate 170 to move back and forth are provided. The carrier plate 170 can be driven to move back and forth by using the lower lead screw groups 180, and it is convenient for the formed 3D tire model to be unloaded.

[0028] The two sets of lower lead screw groups 180 move synchronously. A limiting frame 190 for limiting the forward movement of the carrier plate 170 is provided on the front side of the two sets of lower lead screw groups 180. Several temperature sensors for detecting the position temperature of the print head 200 are provided on the outer side of the lower end of the print head 200. A display screen 120 for numerically displaying the temperature of the temperature sensors on the outer side of the print head 200 is provided at the middle position on the front side of the support 110. The temperature of the temperature sensors on the outer side of the print head 200 can be numerically displayed by using the display screen 120.

[0029] The vertical moving frame 130 includes a vertical guide column 13a and a vertical power motor 13f. A set of vertical guide columns 13a are provided inside each set of vertical moving frames 130.

As shown in the attached drawings of the specification Figure 1 , the staff adjusts the vertical power motor 13f according to the specific position of the 3D printing and drives the vertical lead screw 13b to rotate, thereby driving the moving frame 13d to move along the vertical guide post 13a, moving the horizontal power motor 13e and the horizontal lead screw 140 up and down. Then, the moving seat 150 is driven to move left and right by the horizontal power motor 13e and the horizontal lead screw 140, so that the print head 200 at the lower end of the moving seat 150 is adjusted in two axes to facilitate 3D printing operations. Moreover, since a set of lower lead screw groups 180 for driving the carrier plate 170 to move back and forth are provided on both the left and right sides at the lower end of the carrier plate 170, a small adjustment of the carrier plate 170 by the lower lead screw groups 180 can meet the third-axis adjustment of the 3D printing position. At the same time, the lower lead screw groups 180 can drive the carrier plate 170 to move back and forth, facilitating the staff to take out the entire carrier plate 170 and the blanking of the formed 3D tire model.

[0032] Please refer to Figures 1 - 3 , as the second embodiment of the present utility model: Based on the description in the above embodiment, further, since several temperature sensors for detecting the position temperature of the print head 200 are provided on the outer side of the lower end of the print head 200, and a display screen 120 for numerically displaying the temperature of the temperature sensors on the outer side of the print head 200 is provided at the middle position on the front side of the bracket 110, the temperature of the temperature sensors on the outer side of the print head 200 can be numerically displayed by using the display screen 120, facilitating the staff to timely check the spraying situation of the print head 200 on the 3D printing material and quickly adjust it.
