For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] See also Figures 1 to 3 The present application provides a screen printing screen, comprising a screen 1, a first screen frame 2 and a second screen frame 3, wherein the screen 1 is arranged between the first screen frame 2 and the second screen frame 3, and the first screen frame 2 presses the edges of the screen 1 tightly against the second screen frame 3 to achieve tensioning of the screen 1.

[0033] Specifically, the first net frame 2 is formed by a plurality of connecting rods, and two adjacent connecting rods are connected by a first elastic member 22, so that the connecting rods can move toward the outside of the first net frame 2, thereby changing the relative position between the two adjacent connecting rods; the second net frame 3 includes a net drawing frame body 31, a positioning groove 32, a connecting assembly 33 and a net stretching member 34; an annular groove 311 is formed on the side of the net drawing frame body 31 facing the first net frame 2, and the annular groove 311 is arranged along the circumference of the net drawing frame body 31, and a plurality of positioning grooves 32 are arranged, and the plurality of positioning grooves 32 are respectively arranged in the annular groove 311, and can be moved along the annular groove 311. 11 moves in the width direction, the positioning groove 32 is connected to the connecting rod accordingly, the connecting rod presses the edge of the wire mesh 1 into the positioning groove 32, and the wire mesh 1 can be initially fixed, the connecting assembly 33 passes through the two groove walls of the positioning groove 32 respectively, the mesh stretching member 34 is arranged on the outside of the mesh stretching frame 31, one end of the connecting assembly 33 extends to the outside of the mesh stretching frame 31, and is connected to the mesh stretching member 34, the mesh stretching member 34 can rotate relative to the mesh stretching frame 31, and is fixed on the mesh stretching frame 31, when the mesh stretching member 34 rotates, it can drive the positioning groove 32 to move toward the outside of the mesh stretching frame 31, so as to realize the tightening of the wire mesh 1. When the mesh stretching member 34 is loosened, the side of the mesh stretching member 34 connected to the connecting assembly 33 abuts against the outer wall of the mesh stretching frame 31, and after the mesh is stretched, the side of the mesh stretching member 34 connected to the connecting assembly 33 is away from the mesh stretching frame 31. When the screen is stretched, the screen 1 is first covered on the second screen frame 3, and then the screen 1 is pressed into the positioning groove 32 by the first screen frame 2, so that the screen 1 is initially fixed, and the screen stretching member 34 is turned over to drive the connecting assembly 33 to move to the outside of the screen stretching frame 31, thereby driving the positioning groove 32 and the connecting rod to move toward the outside of the screen stretching frame 31 to achieve the tensioning of the screen 1. The above screen structure is simple and can quickly complete the screen stretching operation of the screen 1. The first screen frame 2 simultaneously presses down and fixes the edges of the screen 1 so that the screen 1 is evenly stressed. After the screen stretching member 34 is turned over and fixed on the screen stretching frame 31, the screen 1 is evenly tightened on all sides, and there is no need to adjust the tension of the screen 1, which reduces the dependence of the screen stretching operation on the operator's experience and technical proficiency.

[0034] like Figure 4 , Figure 5 and Figure 7As shown, the positioning groove 32 includes a first groove body portion 321 and a second groove body portion 322 which are stacked, the first groove body portion 321 is arranged above the second groove body portion 322, the first groove body portion 321 is provided with an opening toward the first mesh frame 2, the first mesh frame 2 presses the wire mesh 1 in the first groove body portion 321, the connecting component 33 is passed through the second groove body portion 322, and one end of the connecting component 33 is limited outside the groove wall on one side of the second groove body portion 322 away from the mesh stretching member 34, so that when the connecting component 33 moves toward the outside of the mesh frame 31, it can drive the positioning groove 32 to move synchronously to achieve the mesh stretching effect. The bottom of the first groove body portion 321 separates the first groove body portion 321 from the second groove body portion 322, so that the movement of the connecting component 33 will not affect the screen 1 and the first screen frame 2, and the edge of the screen 1 can be pressed tightly against the bottom of the first groove body portion 321, thereby improving the connection stability between the first screen frame 2, the screen 1 and the second screen frame 3, and ensuring the printing effect of the screen 1 print.

[0035] like Figure 4 and Figure 5 As shown, Figure 4 It is a schematic diagram of the positions of the connecting component 33, the positioning groove 32 and the mesh frame 31 when the mesh is not stretched (the mesh stretching member 34 is loosened). Figure 5 The schematic diagram of the position of the connecting assembly 33, the positioning groove 32 and the mesh frame 31 after the mesh is stretched (the mesh stretching member 34 is turned over and fixed at the bottom of the mesh stretching frame 31). The connecting assembly 33 includes a transmission rod 331 and a connecting member 332. One end of the transmission rod 331 passes through the side of the mesh stretching frame 31 close to the mesh stretching member 34 and the two groove walls of the second groove body 322, and is limited to the side of the second groove body 322 away from the mesh stretching member 34. The connecting member 332 is passed through the other end of the transmission rod 331 and is rotatably connected to the mesh stretching member 34. The transmission rod 331 can move in a direction away from or close to the inner side of the mesh frame 31. Before the screen is stretched, the positioning groove 32 is placed at a position of the annular groove 311 close to the inner side of the mesh frame 31. At this time, the connecting member 332 is located on the side of the mesh stretching member 34 close to the outer wall of the mesh frame 31. When the mesh stretching member 34 flips over, the connecting member 332 flips to the side of the mesh stretching member 34 away from the outer wall of the mesh frame 31, and the transmission rod 331 is driven by the connecting member 332 to move toward the outside of the mesh frame 31, thereby driving the positioning groove 32, as well as the connecting rod and the screen 1 in the positioning groove 32 to move toward the outside of the mesh frame 31, thereby realizing the mesh stretching operation.

[0036] like Figure 5 , Figure 6 and Fig. 9As shown, the mesh stretching member 34 includes a handle portion 341 and a fixing portion 342. Two fixing portions 342 are provided. The two fixing portions 342 are respectively provided at both ends of the handle portion 341. One end of the fixing portion 342 is connected to the handle portion 341, and the other end of the fixing portion 342 is connected to the connecting component 33. The fixing portion 342 is bent to form a bending area 3421. When the mesh stretching member 34 fixes the wire mesh 1 to the mesh stretching frame 31, the bending area 3421 abuts against the bottom and the outer wall of the mesh stretching frame 31. By fixing the mesh stretching member 34 to the outside of the mesh stretching frame 31, the pulling action of the connecting component 33 on the positioning groove 32 can be maintained, so that the wire mesh 1 fixed in the positioning groove 32 can be kept in a taut state.

[0037] like Fig. 9 As shown, two ear bodies 3422 are arranged on one end of the fixing part 342 close to the transmission rod 331, and the two ear bodies 3422 are arranged at intervals. The transmission rod 331 extends between the two ear bodies 3422, and the connecting member 332 passes through the transmission rod 331 and the two ear bodies 3422 respectively, and is fixed on the two ear bodies 3422. The connecting member 332 can be selected from connecting parts such as pins, and the structure is simple. The transmission rod 331 is arranged between the two ear bodies 3422, so that when the mesh stretching member 34 is turned over, the force of the connecting member 332 is stable, thereby ensuring the mesh stretching effect.

[0038] like Figure 4 and Figure 5 As shown, in order to enable the connection assembly 33 to automatically reset when the screen 1 is replaced and the mesh stretching member 34 is loosened, the connection assembly 33 also includes a second elastic member 333, which is sleeved on the transmission rod 331 and limited between the positioning groove 32 and the groove wall of the annular groove 311 close to the mesh stretching member 34. When the mesh is stretched, the mesh stretching member 34 drives the positioning groove 32 to move toward the outside of the mesh stretching frame 31, so that the positioning groove 32 close to the groove wall inside the mesh stretching frame 31 presses against the second elastic member 333, and the second elastic member 333 is compressed by force to accumulate elastic potential energy; when the mesh stretching member 34 is loosened, the second elastic member 333 releases the elastic potential energy, drives the positioning groove 32 to move toward the inside of the mesh stretching frame 31, and moves to the initial position, so as to facilitate the subsequent reinstallation of the mesh 1 and the first mesh frame 2. In this embodiment, the second elastic member 333 is a compression spring.

[0039] Furthermore, buffer members, such as rubber washers, are provided between the second elastic member 333 and the annular groove 311, between the second elastic member 333 and the groove wall of the positioning groove 32 close to the inside of the mesh frame 31, and between the end of the transmission rod 331 away from the mesh stretching member 34 and the outer wall of the positioning groove 32, so as to avoid rigid collision between the second elastic member 333 and the annular groove 311, between the second elastic member 333 and the positioning groove 32, and between the transmission rod 331 and the positioning groove 32.

[0040] like Figure 1 and Figure 8 As shown, the first mesh frame 2 includes a first connecting rod 21a and a second connecting rod 21b, which are staggered and connected to enclose the first mesh frame 2, and the two ends of the first connecting rod 21a are respectively provided with a limiting portion 21a1, and the two ends of the second connecting rod 21b are respectively provided with a third groove body portion 21b1, the notch of the third groove body portion 21b1 faces the length extension direction of the second connecting rod 21b, and the limiting portion 21a1 is limited in the third groove body portion 21b1. In the above, the longitudinal displacement of the first connecting rod 21a and the second connecting rod 21b is limited, so that the first connecting rod 21a and the second connecting rod 21b are always kept on the same horizontal plane, so that the first mesh frame 2 can generate uniform pressure on the screen 1 around.

[0041] In the present embodiment, the first mesh frame 2 is configured to be a rectangle, which is formed by two first connecting rods 21a and two second connecting rods 21b being staggered end to end. The second mesh frame 3 is configured to be a rectangle corresponding to the first mesh frame 2. A mesh stretching member 34 is provided on each outer side of the second mesh frame 3. By simultaneously flipping the mesh stretching members 34 on the corresponding two sides, the opposite sides of the screen 1 can be quickly tightened.

[0042] like Figure 3 As shown, the upper surface of the first mesh frame 2 is not higher than the upper surface of the second mesh frame 3, and the connecting rod of the first mesh frame 2 is adapted to the positioning groove 32 on the second mesh frame 3, thereby improving the connection stability between the first mesh frame 2 and the second mesh frame 3, thereby improving the mesh stretching effect of the silk screen 1.

[0043] like Figure 5 and Figure 8 As shown, the surfaces of both ends of the first connecting rod 21a facing the screen 1 and the surface facing away from the screen 1 are respectively recessed inward to form a limit portion 21a1, and a first surface 21a2 is formed on the side of the first connecting rod 21a facing the limit portion 21a1, and the second connecting rod 21b can abut against the first surface 21a2. Before the screen is stretched, the end of the second connecting rod 21b abuts against the first surface 21a2 toward the side of the first connecting rod 21a. During the stretching process, the first connecting rod 21a and the second connecting rod 21b move outward respectively, and the second connecting rod 21b is no longer in contact with the first surface 21a2. When the screen 1 needs to be removed, the mesh stretcher 34 is loosened, and the first connecting rod 21a and the second connecting rod 21b are moved toward the inner side of the first mesh frame 2 under the elastic action of the first elastic member 22. When the second connecting rod 21b moves to contact the first surface 21a2, the first surface 21a2 limits the second connecting rod 21b, preventing the second connecting rod 21b from continuing to move, thereby ensuring that the first mesh frame 2 can return to its original size.

[0044] like Figure 4 , Figure 5 as well as Figure 8 As shown, a fourth slot body portion 21a4 is provided on the limiting portion 21a1, and the slot of the fourth slot body portion 21a4 is toward the length extension direction of the first connecting rod 21a, and a support block 21a3 is provided in the fourth slot body portion 21a4, and the two ends of the support block 21a3 are respectively connected to the two slot walls of the fourth slot body portion 21a4, and the first elastic member 22 is respectively connected to the support block 21a3 and the slot bottom of the third slot body portion 21b1, so that the first connecting rod 21a and the second connecting rod 21b can drive the first elastic member 22 to extend during the outward movement, and the position of the first elastic member 22 will not be blocked; when the mesh member 34 is loosened, the first connecting rod 21a and the second connecting rod 21b can move to their original positions through the elastic action of the first elastic member 22.

[0045] In summary, the present application connects two adjacent connecting rods of the first mesh frame through a first elastic member, so that the connecting rods of the first mesh frame can move outward during the process of stretching the mesh to compress the wire mesh; by setting a positioning groove corresponding to the first mesh frame in the second mesh frame, and setting the positioning groove as a first groove body part and a second groove body part arranged in a stacked manner, and inserting the connecting component into the second groove body part, it is avoided that the connecting component affects the connection stability between the first mesh frame and the wire mesh, and a mesh stretching member is set on the outside of the mesh stretching frame, and the mesh stretching member is turned over to drive the connecting component to move toward the outside of the mesh stretching frame, thereby driving the positioning groove, the first mesh frame and the wire mesh to move toward the outside of the mesh stretching frame, so as to achieve rapid mesh stretching of the screen, and the edges of the wire mesh are evenly stretched and do not need to be readjusted, thereby improving the effect of mesh stretching and reducing the dependence of the mesh stretching process on the operator's experience and technical proficiency. In addition, the tensioning effect of the wire mesh is controlled by the moving distance of the connecting component, and the moving distance of the connecting component is controllable, so that different mesh stretching processes can easily achieve the same tensioning effect of the wire mesh.

[0046] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and application concept of the present application, and all these changes or substitutions should fall within the protection scope of the claims attached to the present application.
