[0033] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures and technologies are proposed to thoroughly understand the embodiments of the present invention. However, those skilled in the art should clearly understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0034] To make the purpose, technical solutions, and advantages of the present invention clearer, the following will be described through specific embodiments in conjunction with the drawings.

[0035] Figure 1 is the first structural schematic diagram of the frame support device provided by the embodiment of the present invention, Figure 2 is the first structural schematic diagram of the frame support device provided by the embodiment of the present invention with a frame, and is described in detail as follows:

[0036] The frame support device 1 includes: a support platform 11 and an adjustment opening 12.

[0037] The support platform 11 is a flat plate for supporting the frame 2 to be stretched with a net.

[0038] Specifically, the structure of the support platform is a cuboid; the shape of the upper surface of the support platform can be any one of the following: square and rectangle.

[0039] An adjustment opening 12 penetrating the upper and lower surfaces of the support platform 11 is provided on the support platform 11, and the position of the screen frame 2 is adjusted through the adjustment opening 12.

[0040] In the embodiment of the present invention, by providing a support platform and an adjustment opening, the support platform is a flat plate for supporting the screen frame to be stretched, which can ensure a large contact area between the support platform and the screen frame, increase the support area of the screen frame, reduce the deformation of the screen frame caused by support and the deformation of the screen frame during stretching, thereby ensuring the flatness of the screen frame and realizing uniform tension during stretching; an adjustment opening penetrating the upper and lower surfaces of the support platform is provided on the support platform, and the position of the screen frame is adjusted through the adjustment opening, which can achieve accurate alignment of the screen frame, ensure uniform force on the screen frame during stretching, avoid deformation of the screen frame, improve the flatness of the screen frame, and the operation is intuitive and simple, which can improve the efficiency of screen frame alignment.

[0041] In a possible implementation manner, referring to Figure 1 the first structural schematic diagram of the screen frame support device shown, the adjustment opening 12 is composed of a plurality of through holes 121 arranged in an array form.

[0042] In this embodiment, the adjustment opening is composed of a plurality of through holes arranged in an array form, and the screen frame can be adjusted through the through holes; specifically, referring to Figure 2 the figure shown, a group of four through holes is used to support and adjust one screen frame.

[0043] Preferably, when the shape of the through hole is square or rectangular, the sides of the cross-section of the through hole can be parallel to the sides of the cross-section of the support platform, or the included angle between the sides of the cross-section of the through hole and the sides of the cross-section of the support platform is 45°, so as to more accurately stretch the screen frame and ensure uniform force on the screen frame; the above settings of the through hole positions are only two preferred ways, and the relationship between the sides of the cross-section of the through hole and the sides of the cross-section of the support platform can also be adjusted according to the needs during screen frame stretching.

[0044] In a possible implementation manner, referring to Figure 3 the second structural schematic diagram of the screen frame support device shown, the adjustment opening 12 is composed of five port structures 122, and each port structure 122 is composed of four adjacent through holes 121, and the five port structures 122 are respectively located on the diagonal lines of the support platform 11.

[0045] In this embodiment, the adjustment opening is composed of five port structures, and each port structure is composed of four adjacent through holes. The screen frame can be supported and adjusted through the port structure. Specifically, referring to Figure 4 the figure shown, the screen frame can be supported by the support structure between adjacent through holes, and the screen frame can be adjusted through four adjacent through holes.

[0046] Preferably, the five through-hole structures 122 are respectively located on the diagonal lines of the support platform 11 , and the angle between the side of the cross section of the through-hole 121 and the side of the cross section of the support platform 11 is 45°.

[0047] The above-mentioned setting methods of the adjustment opening are only two schematic structures. In actual use, the positions of the adjustment opening and the through holes can be set and changed according to the needs of the screen frame to stretch the screen, so as to achieve the screen stretching of the screen frame.

[0048] The shape of the through hole 121 can be any of the following: square, rectangular and circular. The present invention does not limit the size of the through hole 121 , and the size of the through hole 121 can be any size as long as the screen frame can be adjusted through the through hole 121 .

[0049] In a possible implementation, the ratio of the distance between any two adjacent through holes 121 to the width of the screen frame 2 is in the range of 4 / 3 to 3 / 2.

[0050] In this embodiment, by limiting the relationship between the distance between adjacent through holes and the width of the screen frame, it is possible to ensure that the contact area between the screen frame and the support structure is large, thereby avoiding deformation of the screen frame due to support, and reducing the deformation of the screen frame when the screen is stretched; at the same time, the distance between two adjacent through holes is relatively wide, so that the same through hole can be used to adjust multiple screen frames, and the through holes can be reused so that any four adjacent through holes can be used to place and adjust the screen frame, thereby increasing the number of screen frames when stretching the screen and improving the efficiency of stretching the screen.

[0051] In a possible implementation, the length of the support platform 11 is smaller than the corresponding length of the lifting bracket of the stretching machine, and the width of the support platform 11 is smaller than the width of the lifting bracket.

[0052] In this embodiment, the support platform is fixed on the lifting bracket of the mesh stretching machine during use, and the support platform can be raised and lowered along with the adjustment of the lifting bracket of the mesh stretching machine, so that the mesh frame can be adjusted through the adjustment port later; the length and width of the support platform are slightly smaller than the length and width of the corresponding lifting bracket, and the support platform can be completely placed in the lifting bracket, so that the support platform is evenly stressed, ensuring the stability of the support platform, thereby avoiding uneven stress on the mesh frame and ensuring the stability of the mesh frame.

[0053] In the embodiment of the present invention, by providing a support platform and an adjustment through-hole, the support platform is a flat plate for supporting the screen frame to be stretched. This can ensure a large contact area between the support platform and the screen frame, increase the support area of the screen frame, reduce the deformation of the screen frame caused by support and the deformation of the screen frame during stretching, thereby ensuring the flatness of the screen frame and achieving uniform tension during stretching. An adjustment through-hole penetrating the upper and lower surfaces of the support platform is provided on the support platform. The adjustment through-hole includes a plurality of through-holes. The position of the screen frame is accurately adjusted through the through-holes to achieve accurate alignment of the screen frame. Moreover, the screen frame is supported by the support structure between the through-holes, ensuring a large contact area between the screen frame and the support structure. Each through-hole can place and adjust multiple screen frames. By reusing the through-holes and adjusting multiple screen frames simultaneously, the number of screen frames that can be placed on the support platform at the same time can be increased, thereby increasing the number of screen frames stretched simultaneously and improving the stretching efficiency. Based on the accurate alignment of the screen frame and the large support area, deformation of the screen frame during stretching can be avoided, ensuring uniform force on the screen frame, improving the flatness of the screen frame, with intuitive and simple operation, and being able to improve the efficiency of screen frame alignment.

[0054] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The order of execution of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
