[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] Please also read Figure 1 and Figure 2Now, the net-pulling device for leveling the wire mesh provided by the utility model is described. The net-pulling device for leveling the wire mesh comprises a feeding assembly 10, a collecting assembly 20, a net-pulling mechanism, a detection mechanism 40 and a matching controller. The feeding assembly 10 can be used to place the wire mesh roll to be leveled and tested. The collecting assembly 20 is spaced apart from the feeding assembly 10, and can collect the wire mesh after leveling and testing. The net-pulling mechanism comprises two net-pulling assemblies 30, and the two net-pulling assemblies 30 are spaced apart between the feeding assembly 10 and the collecting assembly 20, and each net-pulling mechanism has a clamp for the wire mesh to pass through, and the two net-pulling assemblies 30 can jointly pull the wire mesh to level it. The detection mechanism 40 is arranged between the two net-pulling assemblies 30 and is located below the wire mesh, and can detect the mesh surface of the transferred wire mesh.

[0041] The mesh-pulling device provided in this embodiment can level the screen. Compared with the prior art, the unwinding component 10 and the rewinding component 20 can ensure the unwinding and rewinding of the screen. The mesh-pulling mechanism and the detection mechanism 40 located therebetween can ensure that the screen can be directly detected during the leveling process. The leveling process and the detection process are integrated, which can improve production efficiency and reduce labor costs, and is highly practical.

[0042] It should be noted that both the unwinding assembly 10 and the receiving assembly 20 are provided with reels, and are driven by servo motors. This technology is prior art and will not be described in detail here.

[0043] In some embodiments, the above-mentioned net assembly 30 can be used as follows Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2 Each mesh pulling assembly 30 includes a base 31, a slide frame 32, a first telescopic structure 33 and a clamping structure 34. The base 31 has a slide rail arranged along the spacing direction of the material discharging assembly 10 and the material receiving assembly 20. The slide frame 32 is slidably arranged on the slide rail. The first telescopic structure 33 is fixed on the base 31 and connected to the slide frame 32, and can drive the slide frame 32 to slide. The clamping structure 34 is arranged in the slide frame 32, and the clamping structure 34 can clamp the wire mesh.

[0044] The working principle is that after the two mesh-pulling assemblies 30 clamp the wire mesh at the same time, the first telescopic structure 33 in one of the mesh-pulling assemblies 30 or both of the mesh-pulling assemblies 30 moves, and the two sliding frames 32 move opposite to each other. At this time, it can ensure that the wire mesh between the two mesh-pulling assemblies 30 is pulled, thereby achieving the flatness of the wire mesh surface.

[0045] The two mesh-pulling assemblies 30 have the same structure and can simultaneously pull the wire mesh in opposite directions, or one of the mesh-pulling assemblies 30 can pull the wire mesh. In addition, this structure also ensures that the discharge assembly 10 can be used as the receiving assembly 20, or the receiving assembly 20 can be used as the discharge assembly 10.

[0046] In some embodiments, the clamping structure 34 may be configured as follows: Figure 2 See the structure shown. Figure 2 The clamping structure 34 includes an upper pressing block 341, a lower pressing block 342 and a second telescopic structure 343. The upper pressing block 341 is slidably arranged in the sliding frame 32 along the vertical direction, and the bottom end of the upper pressing block 341 has an upper abutting surface. The lower pressing block 342 is arranged in the sliding frame 32 and is located below the upper pressing block 341. The top end of the lower pressing block 342 has a lower abutting surface corresponding to the upper abutting surface, and a clamp is formed between the upper abutting surface and the lower abutting surface. The second telescopic structure 343 is fixed on the sliding frame 32, and the second telescopic structure 343 can drive the upper pressing block 341 to move closer to or away from the lower pressing block 342.

[0047] The clamp formed between the upper pressing block 341 and the lower pressing block 342 can ensure the clamping of the wire mesh, thereby ensuring that the wire mesh segment between the two clamps is pulled flat. The second telescopic structure 343 can ensure the driving of the upper pressing block 341, thereby ensuring that the clamping of the wire mesh is clamped, or is released from the clamping of the wire mesh, and its structure is simple and practical.

[0048] It should be noted that the sliding frame 32 can be a rectangular frame.

[0049] In some embodiments, the clamping structure 34 may be configured as follows: Figures 2 to 3 See the structure shown. Figures 2 to 3 , set the horizontal direction perpendicular to the slide rail as the first direction.

[0050] The lower pressing block 342 is slidably set in the sliding frame 32. Preferably, a limiting sliding cavity for vertical sliding of the lower pressing block 342 can be set at the bottom of the sliding frame 32, and a sliding column slidably connected to the limiting sliding cavity can be set on the lower pressing block 342 accordingly. This structure can ensure that the vertical position of the lower pressing block 342 can be adjusted.

[0051] Because during the transmission process of the wire mesh, a suspended structure will be formed between the unwinding assembly and the winding assembly, and after the wire mesh is pulled by the two mesh pulling mechanisms, the length of the wire mesh segment between the unwinding assembly and the winding assembly will be further lengthened. At this time, after the mesh pulling assembly 30 releases the clamping of the wire mesh, the wire mesh will form a concave suspended structure between the unwinding assembly and the winding assembly. At this time, the wire mesh will contact the lower pressure block 342, and in the process of the winding assembly winding the wire mesh, friction will often occur between the wire mesh and the lower pressure block 342, thereby damaging the wire mesh.

[0052] The clamping structure 34 also includes a linkage member, which includes a lever 344 and a pressure rod 345. There are two levers 344, which are respectively located at both sides of the lower pressing block 342 along the first direction, each lever 344 has a first end of the lever 344 and a second end of the lever 344, the lever 344 is rotatably connected to the slide frame 32, and the transfer point is located between the first end of the lever 344 and the second end of the lever 344, and the first end of the lever 344 is provided with a first roller 346 that rolls with the bottom end of the lower pressing block 342. There are two pressure rods 345, which are respectively located at both ends of the upper pressing block 341 along the first direction, and are arranged one-to-one with the two levers 344, each pressure rod 345 is arranged along the vertical direction, the top end is fixedly connected to the upper pressing block 341, and the bottom end is provided with a second roller 347 that rolls with the second end of the corresponding lever 344.

[0053] Specifically, the sliding frame 32 is provided with a hinge seat for the lever 344 to be rotatably connected. The lower pressing block 342 is provided with a contact surface for the second roller 347 to abut against.

[0054] In this regard, the linkage member can drive the lower pressing block 342 upward through the lever 344 and the pressure rod 345 when the upper pressing block 341 is moving downward, so that the upper pressing block 341 and the lower pressing block 342 can move relative to each other to achieve the clamping work. When the upper pressing block 341 is moving upward, the lower pressing block 342 can automatically move downward under the action of gravity to open the clamping mouth, and the position height of the lower pressing block 342 is reduced to avoid contact with the mesh surface of the wire mesh. The linkage member has a simple structure, good linkage effect, and strong practicality.

[0055] In some embodiments, the upper pressing block 341 and the lower pressing block 342 may be formed as follows: Figure 2 See the structure shown. Figure 2 Along the first direction, the length of the upper pressing block 341 is greater than the length of the lower pressing block 342. This structure can ensure that the pressing rod 345 is fixed on the upper pressing block 341, and the pressing rod 345 can extend downward on both sides of the lower pressing block 342. The structure is simple and practical.

[0056] In some embodiments, the above-mentioned net pulling mechanism can be used as follows Figure 1 See the structure shown. Figure 1 The net pulling mechanism also includes a receiving platform 50 located between the two net pulling assemblies 30. The setting of the receiving platform 50 can ensure that the wire mesh between the two net pulling assemblies 30 is received, so as to avoid the wire mesh between the two net pulling assemblies 30 from dragging on the ground.

[0057] In some embodiments, the detection mechanism 40 may be implemented as follows: Figure 1 See the structure shown. Figure 1The detection mechanism 40 is arranged on the receiving platform 50, and the detection mechanism 40 includes a visual camera. The setting of the receiving platform 50 can ensure the installation of the detection mechanism 40, and the detection mechanism 40 is directly installed on the receiving platform 50, which can ensure that the receiving platform 50 protects it. The visual camera is electrically connected to the controller, which can ensure that the mesh surface of the wire mesh is directly detected during the transmission process of the wire mesh. It has a simple structure, can effectively improve production efficiency, and has strong practicality.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
