[0002] Screen printing equipment is a device specially used for screen printing process. It includes screen printing machine body, screen, scraper, ink material, curing equipment and other parts. Screen printing is a common printing method, which is to apply ink or pigment on the screen and then use scraper to force the ink into the pattern or text on the surface of the printing material. Screen printing can be used to print on various materials such as paper, cloth, metal, glass, etc., and is widely used in advertising, packaging, textile, electronic products and other industries.

[0003] However, when printing on cloth, the cloth is laid on the printing equipment. However, due to the soft nature of the cloth, the cloth is prone to wrinkles and deviations during the printing process, which leads to defects in the pattern after the cloth is printed. Utility Model Content

[0021] Furthermore, the laying roller 9 is made of rubber material, and a plurality of traction protrusions 12 surrounding the laying roller 9 are fixedly connected on both sides of the outer wall thereof, and the traction protrusions 12 are relatively inclined to each other to form an "eight"-shaped structure facing the forward direction of the laying roller 9; the traction protrusions 12 are arranged to rotate together with the laying roller 9, and the traction protrusions 12 are relatively inclined to each other to form an "eight"-shaped structure facing the forward direction of the laying roller 9, so that the traction protrusions 12 can pull the cloth to both sides when rotating, thereby increasing the stretch of the cloth during printing, thereby increasing the printing effect of printing on the cloth.

[0022] Furthermore, the clamping groove 11 is a wave-shaped structure, and the structure of the clamping rod 10 corresponds to the clamping groove 11; when the wave-shaped clamping rod 10 is inserted into the clamping groove 11 to squeeze the cloth, it can increase the stability when squeezing and quickly positioning the cloth.

[0023] Furthermore, both ends of the placement plate 3 are arranged in an arc shape; the arcs at both ends of the placement plate 3 can guide the movement of the paving roller 9, thereby preventing the paving roller 9 from getting stuck with the two ends of the placement plate 3 when resetting.

[0026] Working principle: This embodiment provides a rapid positioning device for printing equipment. When in use, the cloth to be printed is placed on the placement plate 3. Then, when the screen printing machine body 1 moves toward the cloth, the linkage frame 6 is squeezed by the screen frame of the screen printing machine body 1. At this time, the linkage frame 6 squeezes the spring telescopic rod 5 to begin to shorten and drive the connecting rod 8 to move downward. The movement of the connecting rod 8 drives the laying roller 9 to move and contact the cloth. As the linkage frame 6 descends, the laying roller 9 begins to be blocked by the placement plate 3 and starts to drive the torsion bar 7 to twist through the connecting rod 8. In this process, the laying roller 9 also begins to rotate on the placement plate 3 and move away from each other, so that the laying roller 9 begins to flatten the cloth. When the laying roller 9 rotates, it will drive the traction protrusion 12 to rotate together. When the traction protrusion 12 rotates, it will pull the cloth to both sides to increase the flatness of the cloth.

[0027] As the linkage frame 6 moves, the clamping rod 10 at the bottom of the linkage frame 6 will be inserted into the clamping groove 11, so as to clamp the edge of the cloth and position it, thereby increasing the stability of the cloth during printing. After the cloth is printed, as the screen printing machine body 1 is reset, the linkage frame 6 will start to reset and move under the elastic force of the spring telescopic rod 5 itself, and the torsion bar 7 will also reset the laying roller 9 under its own torque to prepare for the next screen printing machine body 1 to print the cloth.

[0028] 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.
