[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0024] Please refer to Figures 1-4 The utility model provides a technical scheme:

[0025] Embodiment one: a silk screen printing device convenient to maintain, including mounting plate 1, a pair of sliding grooves 15 are set up in mounting plate 1, scraper 2 is set up in mounting plate 1, and the top of scraper 2 is fixedly connected with sliding plate one 3, and ink injection plate 4 is set up in mounting plate 1, and the top of ink injection plate 4 is fixedly connected with sliding plate two 5, and ink injection plate 4 and sliding plate two 5 are slidably connected in sliding groove 15 respectively, and rotating rod 6 is rotatably connected in the inside of one end of mounting plate 1, and the outer wall of the outer end of rotating rod 6 is fixedly connected with ratchet 7, and rotating column 8 is rotatably connected in the inside of mounting plate 1, and the outer wall of rotating column 8 is fixedly connected with pawl 10, and pawl 10 corresponds with ratchet 7, and the outer wall of rotating rod 6 is fixedly connected with connecting plate 11, and connecting plate 11 is slidably connected with connecting frame 12 in the inside, and a pair of insertion columns 16 are fixed on the inner wall of connecting frame 12 and the inner side wall of the other end of mounting plate 1, and the inner side wall of pawl 10 is fixedly connected with torsional spring 9, and the other end of torsional spring 9 is fixedly connected on the outer wall of mounting plate 1, and torsional spring 9 is sleeved on the outer wall of rotating column 8, and connecting plate 11 is rotatably connected on the top of mounting plate 1, and a pair of springs 13 are fixedly connected on the top of connecting plate 11, and the other end of spring 13 is fixedly connected on the inner wall of connecting frame 12, and insertion hole 14 is set up in the inside of the two ends of sliding plate two 5 and sliding plate one 3, and insertion hole 14 corresponds with insertion column 16, and insertion column 16 is inserted in insertion hole 14.

[0026] When the doctor blade 2 or the ink pad 4 needs to be repaired or replaced, first, the connecting frame 12 is pushed outward, so that the insertion column 16 on the inner wall of the bottom of the connecting frame 12 is separated from the insertion hole 14, at this time, the spring 13 is stretched to a tight state. Then, the pawl 10 is rotated in the clockwise direction, so that the pawl 10 is separated from the ratchet wheel 7, so that when the rotating rod 6 is rotated in the clockwise direction, the ratchet wheel 7 is not hindered, and the connecting plate 11 is rotated in the clockwise direction to the vertical direction. Then, the parts are loosened, and the connecting plate 11 is reset under the rebounding action of the spring 13, and the pawl 10 is reset through the torsional spring 9 and is re-clamped on the ratchet wheel 7. At this time, the ink pad 4 and the doctor blade 2 are pulled outward, and they can be directly pulled out from the sliding groove 15, so as to be quickly disassembled from the mounting plate 1. When installing, the sliding plate one 3 and the sliding plate two 5 are inserted into the sliding groove 15, then the connecting frame 12 is pulled outward, and the rotating rod 6 is rotated in the counterclockwise direction, so as to drive the connecting plate 11 to rotate in the counterclockwise direction to the horizontal direction. After the connecting frame 12 is loosened, the insertion column 16 is inserted into the insertion hole 14 through the rebounding force of the spring 13, so as to realize quick installation. The design of the ratchet wheel 7 and the pawl 10 is very clever, which can effectively prevent the rotation during the rotation. Through the close cooperation between the parts, the maintenance and replacement efficiency of the doctor blade 2 and the ink pad 4 is greatly improved, and the overall work efficiency is improved.

[0027] In the embodiment two, the mounting plate 1 is provided with the fixed frame 19 outside, the workbench 20 is fixedly connected to the top of the fixed frame 19, the supporting frames 26 are fixedly connected to the top of the two ends of the workbench 20, the adjusting screw rods 24 are threadedly connected in the supporting frames 26, the pressing plates 25 are rotatably connected to the bottom of the adjusting screw rods 24, the inner side walls of the supporting frames 26 are provided with a pair of inner grooves 27, the limiting blocks 28 are fixedly connected to the two sides of the pressing plates 25 and are slidably connected in the inner grooves 27, the electric push rods two 21 are fixedly connected to the outer wall of the fixed frame 19, the connecting blocks 22 are fixedly connected to the output end of the electric push rods two 21, the outer shell 17 is fixedly connected to the outer side wall of the connecting blocks 22, a pair of electric push rods one 18 are fixedly connected in the outer shell 17, and the mounting plate 1 is fixedly connected to the output end of the electric push rods one 18.

[0028] First, the to-be-printed part is put on the workbench 20 from the support frame 26. Then, the adjusting screw 24 is rotated to drive the pressing plate 25 to move downward. During the movement of the pressing plate 25, the limiting block 28 limits the movement of the pressing plate 25 in the inner groove 27, ensuring that the pressing plate 25 moves vertically downward. By pressing the to-be-printed part with the pressing plate 25, the to-be-printed part can be fixed and positioned. This design allows different sizes of to-be-printed parts to be quickly fixed, effectively improving work efficiency. After the to-be-printed part is fixed, the electric push rod two 21 outside the mounting plate 1 is started. When the electric push rod two 21 works, it drives the connecting block 22 to move left and right. During the movement of the connecting block 22, the positioning rod 23 limits the movement direction of the connecting block 22, ensuring that the movement direction is accurate. The movement of the connecting block 22 drives the outer shell 17 and the electric push rod one 18 in the outer shell to move left and right synchronously. At this time, the electric push rod one 18 is started, which drives the mounting plate 1, the squeegee 2 and the ink pad 4 on the mounting plate to move downward, thereby starting the printing operation on the to-be-printed part that has been fixed on the workbench 20.
