Detailed implementation manners

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the attached drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figures 1-6 , an embodiment provided by the present invention: an installation and positioning component for a printing machine screen plate, including a screen frame 1,

[0024] The frame 1 is provided with an installation groove 2. Multiple groups of electric telescopic rods 3 are fixedly installed on the upper sides of the front and rear ends of the frame 1. An activity groove 4 is opened in the right end of the frame 1. A positioning component is arranged in the installation groove 2 and the activity groove 4. An adjusting component is arranged in the installation groove 2. The adjusting component is connected with the positioning component. The position of the screen plate installed in the frame 1 is adjusted by the positioning component and the adjusting component of this device. Then, when the screen plate is inserted into the installation groove 2, the positioning component is extruded, so that the positioning component limits and fixes the screen plate. Then, through multiple groups of electric telescopic rods 3, the screen plate is tightly fixed in the frame 1, improving the convenience of installing the screen plate.

[0025] Further, the positioning component includes a connecting rod 5. The connecting rod 5 is slidably installed in the activity groove 4. A double-shaft motor 6 is installed in the connecting rod 5. Winding discs 7 are rotatably installed at both the front and rear ends of the connecting rod 5. The two groups of winding discs 7 are fixedly connected with the double-shaft motor 6. Pulling ropes 8 are wound and installed on the two groups of winding discs 7. Two groups of extrusion rods 9 are fixedly installed on the left side of the connecting rod 5. Two groups of sliders 10 are installed in the left end of the installation groove 2. Limiting plates 11 are rotatably installed in the two groups of sliders 10. A torsion spring 12 is arranged at the connection between the slider 10 and the limiting plate 11. The two groups of pulling ropes 8 are connected with the two groups of limiting plates 11. When the screen plate is inserted into the installation groove 2, the two groups of extrusion rods 9 and the connecting rod 5 are affected. While the connecting rod 5 moves, the two groups of winding discs 7 are driven by the double-shaft motor 6 to wind and pull the two groups of pulling ropes 8, driving the two groups of limiting plates 11 to rotate. The two groups of limiting plates 11 close the left opening of the installation groove 2 and fit with the left side of the screen plate, thus completing the positioning effect of installing the screen plate.

[0026] Further, the adjusting component includes two groups of sliding grooves 13. The two groups of sliding grooves 13 are opened in the front and rear ends of the frame 1. Screws 14 are rotatably installed in the two groups of sliding grooves 13. The left ends of the two groups of screws 14 are inserted into the two groups of sliders 10 through threads. The connection ends of the two groups of sliders 10 and the two groups of sliders 10 are located in the two groups of sliding grooves 13. Synchronous wheels 15 are fixedly installed at the right ends of the two groups of screws 14. A synchronous belt 16 is sleeved on the two groups of synchronous wheels 15. A knob 17 is fixedly installed at the right end of the screw 14 in the front end of the frame 1. By rotating the two groups of screws 14, the two groups of synchronous wheels 15 and the synchronous belt 16 rotate, driving the two groups of screws 14 to drive the two groups of sliders 10 and the two groups of limiting plates 11 to move. And the double-shaft motor 6 drives the two groups of winding discs 7 to rotate to wind and adjust the two groups of pulling ropes 8, so as to position different specifications of screen plates installed in the frame 1.

[0027] Further, the vertical height of the inner walls of the two groups of sliding grooves 13 is greater than the vertical height of the inner wall of the installation groove 2. The two groups of sliding grooves 13 are connected to the front and rear sides of the installation groove 2. According to the heights of the inner walls of the two groups of sliding grooves 13 and the inner wall of the installation groove 2, the two ends of the two groups of sliders 10 in the two groups of sliding grooves 13 are greater than the height of the inner wall of the two groups of installation grooves 2, and the two ends of the slider 10 are in close fit with the inner walls of the sliding groove 13 and the installation groove 2 respectively.

[0028] Furthermore, the front and rear opposite sides of the two groups of sliders 10 are in an L-shaped groove at the connection with the two groups of limit plates 11. The openings of the L-shaped grooves at the upper ends of the two groups of sliders 10 face left. According to the groove shapes of the two groups of sliders 10, this structure enables the two groups of limit plates 11 to rotate 90 degrees on the two groups of sliders 10, facilitating the opening or closing of the left opening of the installation groove 2.

[0029] Furthermore, the two groups of extrusion rods 9 are located inside the right end of the installation groove 2, and the two groups of extrusion rods 9 are opposite to the two groups of limit plates 11 left and right. According to the positional relationship between the two groups of extrusion rods 9 and the two groups of limit plates 11, this structure enables the two groups of limit plates 11 to rotate while the net plate squeezes and moves the two groups of extrusion rods 9. The two groups of limit plates 11 and the two groups of extrusion rods 9 are respectively on the left and right sides of the net plate installed in the installation groove 2, thus enabling the left and right sides of the net plate to be limited and fixed.

[0030] Working principle: When installing the net plate, as shown in Figure 2 、 Figure 3 and Figure 4 、 Figure 5 and Figure 6 , first twist the knob 17. The rotation of the knob 17 drives the rotation of the two groups of screw rods 14 through the two groups of synchronous wheels 15 and the synchronous belt 16. While the two groups of screw rods 14 are rotating, they drive the two groups of sliders 10 to slide in the two groups of chutes 13. The two groups of sliders 10 drive the two groups of limit plates 11 to move. When the two groups of sliders 10 and the two groups of limit plates 11 are sliding, first keep the two groups of limit plates 11 in an open state under the action of the two groups of torsion springs 12, and then insert the net plate into the installation groove 2. After the net plate is completely inserted into the installation groove 2, the right side of the net plate squeezes the two groups of extrusion rods 9 and the connecting rod 5. The connecting rod 5 and the two groups of extrusion rods 9 move to the right in the moving groove 4. While the connecting rod 5 is sliding, the double-shaft motor 6 in the connecting rod 5 drives the two groups of wire reels 7 to wind the two groups of pull ropes 8, thereby winding the two groups of pull ropes 8 connected to the two groups of limit plates 11. The two groups of pull ropes 8 pull the two groups of limit plates 11 to rotate, and the two groups of limit plates 11 rotate to close the left side of the installation groove 2, and the two groups of limit plates 11 are in contact with the net plate on the left side, thus completing the installation and positioning of the net plate. The telescopic movable ends of the multiple groups of electric telescopic rods 3 are inserted into the net frame 1, and the telescopic movable ends of the multiple groups of electric telescopic rods 3 move downward in the installation groove 2 and are in contact with the upper side of the net plate, thereby squeezing and fixing the net plate inserted into the installation groove 2. The multiple groups of electric telescopic rods 3 are prior art, and their basic structures and principles are not elaborated here. The movable rod ends of the multiple groups of electric telescopic rods 3 are movably inserted into the upper end of the net frame 1. After the net plate positioning is completed, downward clamping and fixing are implemented through the electric telescopic rods 3. The above is all the working principles of the present invention.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
