A fixing device 3 and a detachable squeegee 7 are arranged above the screen 2. During the printing process, the fixing device 3 and the squeegee 7 slide on the screen 2 to scrape ink from one side of the screen 2 to the other side, so as to evenly transfer the ink.

[0029] Further, the fixing device 3 comprises a support 31, a fixing base 32, the brush holder 4 is arranged in the support 31, the fixing base 32 is connected with the brush holder 4 through an angle adjusting piece 6, the angle adjusting piece 6 comprises an upper plate 61 and a lower plate 62, the upper plate 61 is movably connected with the lower plate 62 through an adjusting screw 63, the upper plate 61 is fixedly connected with the fixing base 32, the lower plate 62 is fixedly connected with the support 31, and the angle of the brush holder 4 is adjusted by rotating the adjusting screw 63.

[0030] In addition, the angle of the brush holder 4 can adjust the amount of ink transmission, when the angle increases, the amount of ink increases, when the angle decreases, the amount of ink decreases, so that the amount of ink can be accurately controlled according to the printing requirement, and the ink can be uniformly transmitted to the screen 2.

[0031] Referring to FIGS. 1-4, Figure 4 Figure 7 Figure 8 As shown in the drawings, the brush holder 4 is slidably installed in the support 31 through a sliding groove 311, the sliding groove 311 is arranged to make the movement and adjustment of the brush holder 4 more convenient, and the maintenance and adjustment are facilitated, when the brush holder 4 needs to be replaced for maintenance, the brush holder 4 can be slid to move out of the support 31 for cleaning and replacement, in addition, through the sliding cooperation of the sliding groove 311, the friction and wear of the brush holder 4 during movement can be reduced, thereby prolonging the service life of the brush holder 4.

[0032] Further, the brush holder 4 comprises a brush 41, a connecting plate 42, and a pressing plate 43, the brush 41 is provided with a brush head 411, the connecting plate 42 is provided with a plurality of grooves 421, the brush 41 penetrates the grooves 421, the pressing plate 43 is provided with a plurality of grooves 431 matched with the grooves 421, one end of the brush head 411 abuts against the groove 421, the other end of the brush head 411 abuts against the groove 431, and the two ends of the brush head 411 are inserted into the grooves 421 and 431 in interference fit, through the fixation of the two ends of the brush head 411, the stability of the brush 41 is enhanced, thereby reducing the shaking and displacement of the brush 41 in the running state, and the fixation of the two ends of the brush head 411 makes the replacement of the brush 41 simple and fast, only the pressing plate 43 needs to be disassembled to replace the brush 41, thereby greatly reducing the cost and time of frequent replacement of the brush 41.

[0033] In addition, the fixation of the two ends of the brush head 411 can better disperse the pressure received by the brush 41 during work, reduce the wear of the brush 41, and thereby prolong the service life, and such structure is simpler and more intuitive, easy to operate, and can realize the fixation and replacement of the brush 41 without complex structure.

[0034] Referring to FIGS. 1-4, Figure 5 Figure 6 ​​​As shown, the independent design of the brush 41 facilitates separate replacement, which can save cost and improve work efficiency by disassembling the single worn or damaged brush 41; and the brush 41 can accumulate bacteria during use, and regular replacement or disassembly of the single brush 41 can reduce the breeding of bacteria and maintain the overall cleaning efficiency of the brush 41.

[0035] Further, the brush 41 is arranged in a long-short double-row parallel design, which can ensure more uniform distribution of ink on the screen 2; and the long brush 41 can reach the fine part of the pattern, while the short brush 41 can cover the flat part, which can improve the printing precision and adaptability.

[0036] In addition, the long brush 41 helps to deliver more ink, while the short brush 41 can ensure uniform distribution of ink on the surface of the screen 2, and the combination of long and short brushes 41 can improve the delivery efficiency of ink and printing speed, that is, the use of long-short double-row parallel brush 41 on the screen printing machine can improve the uniformity and adaptability of printing.

[0037] Reference Figure 1 As shown, the bearing table 1 is provided with a lifting mechanism 5, the lifting mechanism 5 includes a base 51, a guide plate 52, the guide plate 52 is provided with a guide rail 521, the fixing device 3 is slidably connected to the guide rail 521 through a connecting plate 522, the guide plate 52 drives the fixing device 3 to slide up and down along the base 51, so that the bristle holder 4 can displace up and down with the fixing device 3. The up and down displacement of the bristle holder 4 can set the distance between the brush 41 and the screen 2 according to the printing requirement, to ensure the printing effect; at the same time, when the brush 41 needs to be replaced, the bristle holder 4 can be quickly adjusted to the appropriate position for operation, thereby enhancing the convenience of replacing the brush 41.

[0038] Further, the guide rail 521 is arranged obliquely on the guide plate 52, and the bristle holder 4 obliquely displaces on the guide rail 521; when the bristle holder 4 works, the long brush 41 first contacts the screen 2 and waits until the long brush 41 is almost out of ink, and the obliquely arranged guide rail 521 makes the short brush 41 contact the screen 2, and the short brush 41 continues to deliver ink, that is, the obliquely arranged guide rail 521 makes the ink more uniformly delivered on the screen 2.

[0039] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
