[0022] The fixing mechanism includes a locking rod 12, which is symmetrically arranged on the outside of the fixing plate 6, and one end of the locking rod 12 penetrates the fixing plate 6 to the inside of the fixing groove 7, the locking rod 12 penetrates the outer wall of the fixing plate 6 and is slidably connected to the inner wall of the fixing plate 6 where it penetrates, the outer wall of the fixing plate 6 is fixedly connected with a symmetrically arranged fixing sleeve 13, the inner wall of the fixing sleeve 13 is fixedly connected with a first adjustment sleeve 14, the end of the first adjustment sleeve 14 is staggered with a plurality of evenly arranged first card grooves 15 and second card grooves 16, the inner wall of the fixing sleeve 13 is fixedly connected with a second adjustment sleeve 17, the end of the second adjustment sleeve 17 is opened with a plurality of evenly arranged guide grooves 18, the inner wall of the guide groove 18 is inclined, the opening between the first card groove 15 and the second card groove 16 is inclined, and the other end of the locking rod 12 is rotated It is movably connected with an adjusting rod 19, and the outer wall of the adjusting rod 19 is fixedly connected with a plurality of sliders 20, and the sliders 20 are of a diamond-shaped structure. The inner end wall of the fixing sleeve 13 is fixedly connected with a spring 21, and the other end of the adjusting rod 19 is rotatably connected with a turntable 22, and the other end of the turntable 22 is fixedly connected with the other end of the spring 21; when the wire mesh needs to be replaced, one end of the wire mesh is lifted upward, so that the fixing mechanism can clamp the bonding plate 9, so that the bonding plate 9 no longer fixes the frame of the wire mesh, and the wire mesh can be directly pulled out. Similarly, a new wire mesh is inserted into the fixing groove 7 and one end of it is lifted upward, so that the fixing mechanism can release the bonding plate 9, so that the bonding plate 9 fixes the wire mesh, thereby completing the rapid replacement of the wire mesh, thereby reducing the time required for replacing the wire mesh, and reducing production time and cost.

[0023] Furthermore, one end of the locking rod 12 that passes through the fixing groove 7 can be inserted into the locking hole 11, and the lower side of the end that passes through the fixing groove 7 is inclined to ensure that the locking hole 11 can be accurately inserted into the locking hole 11, and the bonding plate 9 is fixed and released by the limiting plate 10.

[0024] Furthermore, a rubber patch 23 is fixedly connected to the bottom of the bonding plate 9; through the provision of the rubber patch 23, the bonding plate 9 squeezes the frame of the screen through the rubber sheet, thereby increasing the stability of the bonding plate 9 when fixing the screen.

[0025] Furthermore, a plurality of rubber comb teeth 24 are provided at the bottom of the rubber patch 23; when the bonding plate 9 is twisted to fit the frame of the screen, the rubber comb teeth 24 at the bottom of the rubber patch 23 will first contact the frame of the screen, and as the bonding plate 9 continues to twist, the rubber comb teeth 24 will bend, thereby fitting the frame of the screen and increasing the stability when fixing the screen.

[0026] Furthermore, both ends of the bonding plate 9 are arranged in an arc shape, so that the screen can be more easily inserted between the bonding plate 9 and the bottom inner wall of the fixing groove 7 .

[0027] Working principle: This embodiment provides a cardboard screen printing device. When in use, the screen is inserted between the laminating plate 9 and the bottom inner wall of the fixing groove 7. The laminating plate 9 is fitted with the frame of the screen through the torsion force of the torsion spring of the hinge rod 8, so as to fix the screen. The Y-axis moving platform 2 drives the X-axis moving platform 3 and the connecting frame 5 to move toward the base 1. The cardboard is placed on the base 1, so that the bottom of the screen is fitted with the cardboard. The X-axis moving platform 3 drives the scraper 4 to move on the upper side of the screen, so as to complete the printing.

[0028] When the screen needs to be replaced, one end of the screen is lifted upward so that the frame of the screen presses the bonding plate 9, causing the bonding plate 9 to twist. When the bonding plate 9 twists, the limit plate 10 is driven to twist together, so that the bent lower half of the limit plate 10 pushes the inclined part of the locking rod 12, so that the locking rod 12 begins to squeeze the adjusting rod 19 to move toward the inside of the fixing sleeve 13, and the adjusting rod 19 drives the slider 20 to move together in the second slot 16 during the movement. After moving, the slider 20 contacts the inner wall of the guide slot 18 opened on the second adjusting sleeve 17, and is blocked by the guide slot 18 and begins to rotate. At this time, the screen is gradually lowered, and the bonding plate 9 will begin to twist under its own torque, causing the limit plate 10 to start to reset and move. As the plate 10 moves, the spring 21 will push the adjusting rod 19 and the locking rod 12 to move together through the turntable 22 under its own elastic force, and the slider 20 on the adjusting rod 19 will contact the inclined portion between the first card slot 15 and the second card slot 16 as the adjusting rod 19 moves, so that the slider 20 is guided to drive the adjusting rod 19 to rotate again, so that the slider 20 is stuck in the first card slot 15, and the adjusting rod 19 will push the locking rod 12 to extend. At this time, as the screen is gradually lowered, as the limit plate 10 moves against the plate 9, the locking rod 12 will be inserted into the lock hole 11, so that the locking rod 12 fixes the bonding plate 9 through the limit plate 10, so that the bonding plate 9 cannot be reset and twisted, and the screen can be pulled out at this time;

[0029] Insert a new wire mesh between the bonding plate 9 and the inner wall at the bottom of the fixing groove 7, and lift the wire mesh upward. Similarly, the lifting of the wire mesh causes the bonding plate 9 to drive the limiting plate 10 to move, so that the inner wall of the locking hole 11 on the limiting plate 10 and the bending part of the limiting plate 10 push the locking rod 12 in turn, so that the locking rod 12 pushes the adjusting rod 19 to move inside the fixing sleeve 13, so that the slider 20 enters the second card groove 16, so that the second card groove 16 blocks the slider 20, so that the length of the locking rod 12 extending into the fixing groove 7 is not enough to be inserted into the locking hole 11, so that the bonding plate 9 can be twisted to fit the frame of the wire mesh under the torsion of the hinge rod 8, thereby fixing the wire mesh.

[0030] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
