In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The following will further describe the present utility model in detail with reference to the accompanying drawings.

[0024] As Figures 1-6 shown, a printing and dyeing device for facilitating the replacement of a screen includes a printing and dyeing frame 1, a screen 2, and a fixing frame 3. The printing and dyeing frame 1 is rectangular. A rectangular edge frame 4 is fixed along the edge of the center of the bottom wall of the printing and dyeing frame 1. The screen 2 is fixed on the edge frame 4. The fixing frame 3 presses and fixes the screen 2 on the edge frame 4. A fixing member 5 is provided between the fixing frame 3 and the edge frame 4 to fix the fixing frame 3. The screen 2 is made of nylon fiber or polyester fiber material, which is relatively soft and has certain toughness and elasticity. The area of the screen 2 is larger than the areas of the edge frame 4 and the fixing frame 3, so that the four sides of the screen 2 can be pressed by the fixing frame 3 at the outer edge of the edge frame 4. The fixing frame 3 is rectangular and the shape of the inner wall thereof coincides with the shape of the outer wall of the edge frame 4. There is a gap between the inner wall of the fixing frame 3 and the outer wall of the edge frame 4, and the screen 2 is pressed between the inner wall of the fixing frame 3 and the outer wall of the edge frame 4.

[0025] As Figure 6As shown, the fixing component 5 includes a clamping groove 7 and a clamping block 6. A limiting side plate 8 is fixed to the bottom wall of the printing frame 1 near the outer side wall of the edge frame 4. A limiting cross plate 9 perpendicular to the limiting side plate 8 is provided on the limiting side plate 8. The clamping block 6 is slidably arranged on the limiting cross plate 9 close to the bottom wall of the printing frame 1. The clamping groove 7 is arranged on the outer side wall of the fixing frame 3. A plurality of springs 11 are provided at the connection between the outer side wall of the limiting side plate 8 and the outer side wall of the clamping block 6. An external connection plate 10 is fixed to the outer side wall of the clamping block 6 parallel to the outer side wall of the edge frame 4, which is convenient for pushing the clamping block 6 to move. The clamping groove 7 is T-shaped, and the width of the vertical end is greater than the width of the limiting cross plate 9, which is convenient for the limiting cross plate 9 to pass through and clamp the clamping block 6 in the clamping groove 7 to fix the fixing frame 3. The longitudinal section of the clamping block 6 is L-shaped, and the top angle of the clamping block 6 close to the clamping groove 7 is rounded, which can automatically snap the clamping block 6 into the clamping groove 7.

[0026] As Figure 4 shown, pressing grooves 13 are provided at the four corners of the edge frame 4, and pressing blocks 12 corresponding to the pressing grooves 13 are provided at the four corners of the fixing frame 3. The pressing blocks 12 press the four corners of the screen 2 into the pressing grooves 13.

[0027] As Figure 3 shown, two groups of limiting posts 14 are symmetrically provided at the upper and lower ends of the bottom wall of the printing frame 1 respectively. Connection plates 15 are fixed to the upper and lower ends of the fixing frame 3 respectively. Limiting holes 16 are provided on the connection plates 15. The limiting holes 16 correspond to the limiting posts 14 one by one. The limiting posts 14 are passed through the limiting holes 16 to preliminarily limit the fixing frame 3.

[0028] As Figure 1 、 2 As shown in Figures 3 and 5, the thickness of the fixing frame 3 and the height of the limiting posts 14 are both less than the thickness of the edge frame 4, so that the screen 2 is close to the bottom wall of the edge frame 4, thereby pressing the screen 2 against the upper surface of the fabric for printing the fabric.

[0029] During specific use, when fixing the screen 2, the screen 2 is laid flat on the edge frame 4, the fixing frame 3 is brought close to the edge frame 4, and the screen 2 is pressed tightly between the inner side wall of the fixing frame 3 and the outer side wall of the edge frame 4. At this time, the pressing block 12 presses the screen 2 tightly in the pressing groove 13, further increasing the stability. During the process of the fixing frame 3 pressing the screen 2, the clamping block 6 is squeezed, and the clamping block 6 squeezes the spring 11 in the reverse direction. The spring 11 is compressed. When the limiting cross plate 9 is placed at the bottom of the clamping groove 7, under the action of the self-restoring force of the spring 11, the clamping block 6 is snapped into the clamping groove 7 to fix the fixing frame 3, thereby fixing the screen 2. The prepared dye is placed in the printing frame 1. The screen 2 is close to the upper surface of the fabric, and the dye is scraped from the screen 2 onto the fabric through a squeegee for printing the fabric;

[0030] When disassembling the screen mesh 2, push the external connecting plate 10 towards the outside of the fixed frame 3 to drive the clamping block 6 out of the clamping groove 7, thereby releasing the limit on the fixed frame 3, and then the fixed frame 3 can be removed, and thus the screen mesh 2 can be removed, which is convenient for replacing the screen mesh 2.

[0031] The above has described the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the purpose of the creation of the present utility model, without creative design, they design similar structural manners and embodiments to this technical solution, which shall fall within the protection scope of the present utility model.
