Description

Technical Field

[0001] This application relates to the field of steel mesh installation, and in particular to a steel mesh support device. Background Technology

[0002] In related technologies, a stencil is installed between multiple support members, each equipped with a tensioning mechanism. This tensioning mechanism connects and tensions the stencil to ensure it remains flat during use. However, when the support members deform during manufacturing or installation, the tensioning mechanisms installed in the deformed areas of the support members shift with the support members. When multiple tensioning mechanisms simultaneously tension the stencil, those installed in the deformed areas cannot fully tension the stencil, resulting in an uneven surface. During printing using the stencil, localized areas may wrinkle, bulge, or loosen due to insufficient tension, leading to distorted printed patterns or uneven ink distribution, severely impacting print quality.

DETAILED DESCRIPTION

[0047] The following will be described in detail with reference to the accompanying drawings. Figures 1-9 The present application will be further described in detail.

[0048] The embodiments of the present application disclose a steel mesh supporting device 100.

[0049] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 8 The steel mesh supporting device 100 comprises a plurality of supporting members 1 and a tensioning mechanism 2.

[0050] The plurality of supporting members 1 are arranged in sequence along the circumferential direction of the steel mesh supporting device 100, and any two adjacent supporting members 1 are connected and matched, the supporting member 1 defines a mounting space 11, and the mounting space 11 forms an open port 12 at the top wall of the supporting member 1.

[0051] In some specific embodiments, the supporting member 1 is four, the four supporting members 1 are arranged in sequence along the circumferential direction of the steel mesh supporting device 100, and the four supporting members 1 are sequentially connected at the head and tail and collectively enclosed to form a rectangle, that is, the head of one of the two adjacent supporting members 1 is connected and matched with the tail of the other supporting member 1.

[0052] Each supporting member 1 is provided with at least one tensioning mechanism 2, the plurality of tensioning mechanisms 2 are arranged at intervals along the length direction of the supporting member 1, the tensioning mechanism 2 comprises a tensioning member 21 and a connecting member 22, the tensioning member 21 is located in the mounting space 11 and movably connected and matched with the supporting member 1, and the tensioning member 21 passes through the open port 12, the connecting member 22 is located outside the supporting member 1 and opposite to the open port 12, specifically, along the height direction of the steel mesh supporting device 100, the connecting member 22 is located above the open port 12, the height direction of the steel mesh supporting device 100 can refer to the up-down direction in Figure 2 , the connecting member 22 is connected and matched with the tensioning member 21 and the steel mesh, and the tensioning member 21 drives the connecting member 22 to tension or relax the steel mesh when being driven, the steel mesh is located between the plurality of supporting members 1, and the steel mesh has a primary tensioning state and a secondary tensioning state.

[0053] It should be noted that the plurality of tensioning mechanisms 2 perform two tensioning actions on the steel mesh, the steel mesh is in the primary tensioning state when the tensioning mechanism 2 completes the first tensioning action, and the steel mesh is in the secondary tensioning state when the tensioning mechanism 2 completes the second tensioning action.

[0054] In the primary tensioning state, the plurality of tensioning members 21 collectively drive the connecting member 22 to move a first preset distance, and in the secondary tensioning state, the tensioning member 21 far from the end of the supporting member 1 among the plurality of tensioning members 21 drives the connecting member 22 to move a second preset distance, so that the edge line of the steel mesh is a straight line, and the edges of the plurality of steel meshes are enclosed to form a plane.

[0055] In some specific embodiments, each support 1 is provided with three tensioning mechanisms 2, two of the three tensioning mechanisms 2 are arranged close to the end of the support 1, and one of the three tensioning mechanisms 2 is arranged away from the end of the support 1.

[0056] When the tensioning mechanism 2 performs a tensioning action on the steel mesh, all the tensioning members 21 in each support 1 are driven, the tensioning members 21 drive the corresponding connecting members 22 to move away from the center point of the steel mesh by a first preset distance, the connecting members 22 tension the steel mesh, the steel mesh is in a first tensioning state, the tensioning mechanism 2 installed in the non-deformed area of the support 1 completely tensions the corresponding area of the steel mesh, and the tensioning mechanism 2 installed in the deformed area of the support 1 does not completely tension or over-tensions the corresponding area of the steel mesh.

[0057] It should be noted that the deformation of the support 1 refers to the bending of the support 1, and the deformed area of the support 1 refers to the bending area of the support 1. The support 1 can bend towards the center point of the steel mesh, or the support 1 can bend away from the center point of the steel mesh. When the support 1 bends towards the center point of the steel mesh, the tensioning mechanism 2 installed in the deformed area of the support 1 does not completely tension the corresponding area of the steel mesh, and when the support 1 bends away from the center point of the steel mesh, the tensioning mechanism 2 installed in the deformed area of the support 1 over-tensions the corresponding area of the steel mesh.

[0058] Then, the tensioning member 21 in the tensioning mechanism 2 installed in the deformed area of the support 1 is driven, that is, the tensioning member 21 away from the end of the support 1 in the plurality of tensioning members 21 is driven, and the tensioning member 21 drives the corresponding connecting member 22 to drive the steel mesh to move by a second preset distance, so that the connecting member 22 completely tensions the corresponding area of the steel mesh, or relaxes the steel mesh to prevent the steel mesh from being continuously over-tensioned, and makes the edge line of the steel mesh a straight line, and the edges of the plurality of steel meshes enclose a plane, so that each area of the steel mesh can be completely tensioned.

[0059] It should be noted that the second preset distance is equal to the bending deformation amount of the support 1, and the deformed area of the support 1 occurs in the area away from the end of the support 1, that is, the deformed area of the support 1 occurs at the center position of the support 1.

[0060] Thus, by driving the corresponding connecting piece 22 to move a first preset distance, the tensioning mechanism 2 installed on the undeformed area of the support piece 1 fully tensions the corresponding area of the steel mesh, the tensioning mechanism 2 installed on the deformed area of the support piece 1 under-tensions or over-tensions the corresponding area of the steel mesh, and by driving the tensioning piece 21 away from the end of the support piece 1 to drive the corresponding connecting piece 22 to move a second preset distance, the connecting piece 22 realizes secondary compensation tensioning or relaxation of the area of the steel mesh corresponding to the deformed area of the support piece 1. Compared with the prior art, the steel mesh can be fully tensioned in the case of deformation of the support piece 1, thereby improving the stability of the printing quality.

[0061] With reference to Figure 2 , Figure 4 and Figure 9 , in some embodiments of the present application, the tensioning mechanism 2 is multiple, the multiple tensioning mechanisms 2 are arranged at intervals along the length direction of the support piece 1, the multiple tensioning mechanisms 2 include a first tensioning mechanism 23 and a second tensioning mechanism 24, the first tensioning mechanism 23 includes a first driving assembly 231 and a first tensioning piece 232, the first tensioning piece 232 is in sliding connection with the support piece 1, and the second tensioning mechanism 24 includes a second driving assembly 241 and a second tensioning piece 242, the second tensioning piece 242 is in pivotal connection with the support piece 1.

[0062] The driving assembly is arranged in the support piece 1 and in transmission connection with the corresponding tensioning piece 21, and is used to drive the corresponding tensioning piece 21 to tension or relax the steel mesh, that is, the first driving assembly 231 is in transmission connection with the first tensioning piece 232, and the first driving assembly 231 is used to drive the first tensioning piece 232 to tension or relax the steel mesh, and the second driving assembly 241 is in transmission connection with the second tensioning piece 242, and the second driving assembly 241 is used to drive the second tensioning piece 242 to tension or relax the steel mesh.

[0063] It should be noted that the deformed area of the support piece 1 can be provided with the first tensioning mechanism 23 or the second tensioning mechanism 24.

[0064] When the tensioning mechanism 2 performs a first tensioning action on the steel mesh, the first driving assembly 231 drives the first tensioning piece 232 to slide away from the center point of the steel mesh, so that the first tensioning piece 232 drives the corresponding connecting piece 22 to move a first preset distance away from the center point of the steel mesh, the second driving assembly 241 drives the second tensioning piece 242 to rotate, so that the second tensioning piece 242 drives the corresponding connecting piece 22 to move a first preset distance away from the center point of the steel mesh, thereby realizing a first tensioning of the steel mesh, and the steel mesh is in a first tensioning state.

[0065] Then, when the first tensioning mechanism 23 is arranged at the deformation region of the support 1, the first driving assembly 231 drives the first tensioning member 232 to drive the corresponding connecting member 22 to move away from the center point of the steel mesh by a second preset distance, and when the second tensioning mechanism 24 is arranged at the deformation region of the support 1, the second driving assembly 241 drives the second tensioning member 242 to drive the corresponding connecting member 22 to move away from the center point of the steel mesh by a second preset distance, so as to compensate the tension or relaxation of the region of the steel mesh corresponding to the deformation region of the support 1, and finally make the edge line type of the steel mesh tend to be a straight line, and the multiple edges of the steel mesh enclose a plane, so as to ensure that each region of the steel mesh is fully tensioned.

[0066] The first driving assembly 231 and the second driving assembly 241 jointly drive the corresponding tensioning member 21 to perform a first tensioning action on the steel mesh, so that the steel mesh is in a first tensioning state, thereby realizing the preliminary stretching of the whole steel mesh, and then the driving assembly arranged at the deformation region of the support 1 drives the corresponding tensioning member 21 to perform a second tensioning action on the steel mesh, so as to realize the compensation tension or relaxation of the region of the steel mesh corresponding to the deformation region of the support 1, so that the edge line type of the steel mesh is a straight line, and the steel mesh can be fully tensioned, and the flatness and pattern stability of the steel mesh in printing application are improved.

[0067] Referring to Figure 2 and Figure 3 In some embodiments of the present application, the first driving assembly 231 comprises a first driving member 2311, a first housing 2312 and an elastic member 2313, the first housing 2312 defines a driving space 2314, the first driving member 2311 is slidingly arranged in the first housing 2312, the end of the first driving member 2311 extends out of the first housing 2312 and is connected and matched with the first tensioning member 232, the elastic member 2313 is elastically deformedly arranged between the first driving member 2311 and the inner side wall of the first housing 2312, the first driving member 2311 divides the driving space 2314 into a first chamber 2315 and a second chamber 2316, the first chamber 2315 and the second chamber 2316 are both communicated with a first gas pump, and the first gas pump is used for conveying gas to the first chamber 2315 or the second chamber 2316.

[0068] In some specific embodiments, the elastic member 2313 is preferably a spring.

[0069] When the first chamber 2315 is filled with gas, the first driving member 2311 drives the first tensioning member 232 to relax the steel mesh, when the first chamber 2315 is not filled with gas, the elastic member 2313 drives the first driving member 2311 to drive the first tensioning member 232 to tension the steel mesh, and when the second chamber 2316 is filled with gas, the first driving member 2311 drives the first tensioning member 232 to tension the steel mesh.

[0070] Specifically, when the first tensioning mechanism 23 is tensioning the steel mesh, the gas in the first chamber 2315 is exhausted, the elastic member 2313 drives the first driving member 2311 to drive the first tensioning member 232 to slide away from the center point of the steel mesh, and the first tensioning member 232 drives the corresponding connecting member 22 to move away from the center point of the steel mesh, thereby achieving the technical effect of tensioning the steel mesh by the first tensioning mechanism 23.
