Different names such as "rapid prototyping", "3D printing" and "solid free manufacturing" express the characteristics of this technology from different aspects.

[0003] Additive manufacturing technology refers to a scientific and technological system that directly manufactures parts based on the principles of discreteness and accumulation, and driven by the three-dimensional data of parts. Based on different classification principles and understanding methods, additive manufacturing technology also has many names such as rapid prototyping, rapid prototyping, rapid manufacturing, 3D printing, 3D additive printing, etc. Its connotation is still deepening and its extension is constantly expanding.

[0004] In recent years, additive manufacturing has also been applied in the textile industry, but the existing 3D additive printing machine screen frame device cannot raise and lower the screen frame, resulting in different printing results under different printing conditions, resulting in poor additive manufacturing effects.

[0023] like Figure 1 As shown, a 3D additive printing machine screen frame lifting device includes four support columns 1, and the upper ends of the four support columns 1 are commonly fixedly connected with a bearing component 2, which can support the printing plate 23, and the four corners of the upper part of the bearing component 2 are fixedly connected with a buffer mechanism 3, which can achieve a buffering effect when the printing plate 23 is pressed down for printing, and the upper parts of the four buffer mechanisms 3 are commonly fixedly connected with a screen frame component 4, which can achieve the function of installing a screen frame 1 42, and the front and right parts of the screen frame component 4 are symmetrically fixedly connected with a clamping mechanism 5, which can achieve the function of clamping and fixing the support frame 2 41 and the screen frame 1 42, and the right side of the outer side of the bearing component 2 is fixedly connected with a transmission mechanism 6, which can achieve the function of lifting and lowering the height of the screen frame component 4.

[0024] In order to achieve the purpose of supporting the printing plate 23, refer to Figure 2 The bearing component 2 includes a supporting frame 21, and a supporting groove 22 communicating with the outside is opened in the middle of the upper end of the outer surface of the supporting frame 21, which can directly support and place the printing plate 23, and the inner cavity of the supporting groove 22 is movably connected to the printing plate 23.

[0025] In order to achieve the purpose of buffering when the printing plate 23 is pressed down for printing, refer to Figure 2 The buffer mechanism 3 includes a fixed shell 31 , a spring 32 is fixedly connected to the bottom wall of the inner cavity of the fixed shell 31 , and a sliding column 33 is slidably connected to the upper part of the inner cavity of the fixed shell 31 .

[0026] When the second support frame 41 moves downward, the second support frame 41 will drive the four sliding columns 33 to move downward and compress the corresponding springs 32, so that the rebound force of the springs 32 buffers the descending support frame 41.

[0027] In order to achieve the purpose of installing the screen frame 42, refer to Figure 3 The net frame component 4 includes a supporting frame 2 41, which can be used to install the net frame 1 42, and the lower part of the supporting frame 2 41 is movably connected to the net frame 1 42.

[0028] In order to achieve the purpose of clamping and fixing the support frame 2 41 and the screen frame 1 42, refer to Figure 3 The clamping mechanism 5 includes a lower clamping plate 51, and the front end of the lower clamping plate 51 is fixedly connected to a guide plate 52, which can drive the lower clamping plate 51 to move upward at the same time, and the upper part of the guide plate 52 is slidably connected to an upper fixing plate 53, and the front end of the outer surface of the upper fixing plate 53 is fixedly connected to a locking assembly 54, which can realize the function of connecting the upper fixing plate 53 and the lower clamping plate 51 to each other for tight fixation, and the upper end of the outer surface of the lower clamping plate 51 is fixedly connected to the middle part of the lower end of the outer surface of the supporting frame 41, and the lower end of the inner surface of the upper fixing plate 53 is fixedly connected to the middle part of the upper end of the outer surface of the supporting frame 41.

[0029] In order to achieve the purpose of connecting the upper fixing plate 53 and the lower clamping plate 51 to each other and fixing them tightly, refer to Figure 3 The locking assembly 54 includes a threaded sleeve 541, a threaded column 542 is threadedly connected to the middle part of the inner cavity of the threaded sleeve 541, a threaded sleeve 543 is threadedly connected to the lower part of the outer surface of the threaded column 542, and the rear end of the outer surface of the threaded sleeve 543 is fixedly connected to the middle part of the front end of the outer surface of the guide plate 52.

[0030] When the supporting frame 2 41 and the screen frame 1 42 need to be pressed and fixed, the lower clamping plate 51 and the upper fixing plate 53 are clamped and fixed by rotating the threaded column 542 .

[0033] It should be noted that the specific installation method, circuit connection method and control method of the electric telescopic cylinder 62 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0034] The working principle of the utility model is as follows: first, the printing plate 23 to be printed is placed in the inner cavity of the support groove 22, and then the screen frame 42 is installed at the lower part of the support frame 41. At this time, the lower clamping plate 51 and the upper fixing plate 53 are clamped and fixed by rotating the threaded column 542. When it is necessary to raise and lower the height of the screen frame 42, the support frame 41 is driven to be raised and lowered by controlling the electric telescopic cylinder 62 under the recognition and measurement of the distance judgement device located on the left side of the support frame 41. When the support frame 41 moves downward, the support frame 41 will drive the four sliding columns 33 to compress the corresponding springs 32, so that the rebound force of the springs 32 buffers the descending support frame 41, thereby avoiding damage to the printing plate 23 when descending for printing.
