[0023] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1:

[0025] The present application provides a top frame machine for adjusting screen tension, comprising a workbench 1; a support frame 3 is provided on the surface of the workbench 1, and adjustment mechanisms 8 are symmetrically provided at the front and rear ends of the inner side of the support frame 3;

[0026] The adjustment mechanism 8 includes an adjustment plate 801, a threaded hole 802 and an adjustment rod 803. The adjustment plate 801 is symmetrically fixed on the front and rear sides of the support frame 3. The surface of the adjustment plate 801 is provided with threaded holes 802 at equal intervals. The interior of the threaded hole 802 is provided with an adjustment rod 803 through a threaded structure. Frame plates 9 are symmetrically provided on the left and right sides of the inner side of the support frame 3. An elastic mechanism 10 is provided in the inner cavity of the frame plate 9. The lifting mechanism 11 includes a hydraulic cylinder 1101 and a top plate 1102. The hydraulic cylinder 1101 is fixedly installed at the central position of the workbench 1, and the top plate 1102 is fixedly installed on the top of the hydraulic cylinder 1101.

[0027] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, when the device is adjusting the mesh of the screen, the personnel can place the screen inside the frame plate 9, and then operate the hydraulic cylinder 1101 through the operating rod 2, and use the hydraulic cylinder 1101 to drive the top plate 1102 to move upward to lift the mesh of the screen placed inside the frame plate 9. Then, the longitudinal drive mechanism 4 and the transverse drive mechanism 5 are used in conjunction to adjust the position of the microscope 7, and use the microscope 7 to detect the size of the mesh on the surface of the screen. When it is detected that the size of the mesh on the screen is different, the adjustment rods 803 at both ends of the screen are rotated. At this time, the personnel can rotate the adjustment rods 803 on the surface of the adjustment plate 801 so that the adjustment rods 803 rotate downward inside the adjustment plate 801 to squeeze the mesh inside the screen, so that the mesh of the screen can be quickly adjusted, thereby ensuring that the size of the mesh on the screen surface is consistent, which can further ensure the consistency of the mesh of the screen, facilitate subsequent processing operations on the screen, and improve the efficiency and convenience of personnel in screen processing.

[0028] Furthermore, an operating lever 2 is provided on the surface of the workbench 1, a lifting mechanism 11 is provided on the surface of the workbench 1, longitudinal drive mechanisms 4 are provided on the left and right sides of the support frame 3, a transverse drive mechanism 5 is installed on the surface of the longitudinal drive mechanism 4, a slider 6 is installed on the surface of the transverse drive mechanism 5, and a microscope 7 is installed on the inner side of the slider 6;

[0029] Specifically, such as Figure 1 、 Figure 2 As shown, when the personnel places the screen that needs to be adjusted inside the frame plate 9, at this time, by operating the operating lever 2, the longitudinal drive mechanism 4 and the transverse drive mechanism 5 are turned on by the operating lever 2, and the position of the microscope 7 is adjusted by using the longitudinal drive mechanism 4 and the transverse drive mechanism 5. The mesh holes on the surface of the screen are observed through the microscope 7, and then the mesh holes of the screen are adjusted by moving the adjustment mechanism 8 downward, so that the mesh size of the screen can be further made consistent, thereby further improving the quality of the screen.

[0030] Furthermore, the elastic mechanism 10 includes an electric push rod 1001, a fixed plate 1002, a spring 1003 and a slide plate 1004. The electric push rod 1001 is symmetrically fixedly installed on the bottom of the inner cavity of the frame plate 9. The fixed plate 1002 is fixedly installed on the top of the electric push rod 1001. The springs 1003 are evenly installed on the top of the inner cavity of the frame plate 9. The slide plate 1004 is fixedly installed on the bottom of the spring 1003.

[0031] Specifically, such as Figure 1 、 Figure 2As shown, when the device is adjusting the mesh size of the screen, the personnel places the screen inside the frame plate 9. At this time, the screen will squeeze one end of the slide plate 1004, and then squeeze the spring 1003 inside the slide plate 1004. The screen will then be placed on the surface of the fixed plate 1002, and the electric push rod 1001 will be turned on by an external controller. The fixed plate 1002 is driven upward by the electric push rod 1001, so that the screen can be fixedly installed between the fixed plate 1002 and the slide plate 1004, so that the device can adjust the mesh size of the screen. Through the elastic mechanism 10 set inside the frame plate 9, screens of different thicknesses can be placed inside the frame plate 9, which can not only further improve the adaptability of the device.

[0032] Working principle: Place the screen inside the frame plate 9, then operate the hydraulic cylinder 1101 through the operating rod 2, and use the hydraulic cylinder 1101 to drive the top plate 1102 to move up to lift the mesh of the screen 2 placed inside the frame plate 9, and then use the longitudinal drive mechanism 4 and the transverse drive mechanism 5 to adjust the position of the microscope 7, and use the microscope 7 to detect the size of the mesh on the surface of the screen. When it is detected that the size of the mesh on the screen is different, at this time, the adjustment rod 803 opposite to each other at both ends of the screen can be rotated. At this time, the personnel can rotate the adjustment rod 803 on the surface of the adjustment plate 801 to make the adjustment rod 803 rotate and move downward inside the adjustment plate 801 to squeeze the mesh inside the screen, so that the mesh of the screen can be quickly adjusted, which is convenient for subsequent processing operations on the screen and improves the efficiency and convenience of personnel in screen processing.

[0033] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
