Detailed Implementation

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example 1, see Figures 1-4 This embodiment provides a warp and weft mesh unfolding device, including a warp and weft mesh machine outlet 1, which is specifically a part of the warp and weft mesh machine and is used to unload the metal warp and weft mesh after it has been produced by the machine. This is existing technology. An unfolding component 2 is provided on the right side of the warp and weft mesh machine outlet 1. The unfolding component 2 includes a support bar 201, a fixing bar 202 hinged above the support bar 201, and a hinge between the fixing bar 202 and the support bar 201. A fixing rod 203 is fixedly connected below the fixing bar 202, and a screw 204 is rotatably connected above the fixing bar 202. An elastic sheet 205 is threaded on the outer surface of the screw 204. The elastic sheet 205 is made of metal and has a certain degree of elasticity. 5. A limiting sleeve 206 is slidably connected to the outer surface. The elastic sheet 205 is L-shaped. The limiting sleeve 206 is fixedly connected to the right side of the fixing strip 202. A fixing block 207 is fixedly connected to the lower end of the elastic sheet 205. The fixing block 207 is triangular in shape and has an anti-slip layer on its upper surface. The unfolding component 2 also includes a winding drum 208. A belt ruler 209 is fixedly connected to the outer surface of the winding drum 208. There are two winding drums 208 and belt rulers 209. The belt ruler 209 is fixedly connected to the left side of the support strip 201. One end of the belt ruler 209 is connected to the outer surface of the winding drum 208 and is wound up on the winding drum 208. The other end is connected to the left side of the support strip 201. A pull ring 3 is fixedly connected above the fixing strip 202.

[0023] In practical use, the above-mentioned equipment discharges the produced metal warp and weft mesh through the discharge port 1 of the warp and weft mesh machine. After the metal warp and weft mesh is discharged, one end is placed on the support bar 201, and then the fixing bar 202 is flipped downwards to press it onto the warp and weft mesh. At this time, the fixing rod 203 on the fixing bar 202 will be inserted into the hole in the warp and weft mesh. The downward pressure of the fixing bar 202 will drive the limiting sleeve 206 and the elastic plate 205 to descend. The elastic plate 205 will drive the fixing block 207 to descend. When the fixing block 207 passes the support bar 201, the elastic plate 205 will undergo elastic deformation. When the fixing block 207... When the support bar 201 is passed, the elastic sheet 205 will return to its original position, so that the fixing block 207 hooks onto the bottom of the support bar 201. At this time, by rotating the screw 204, the elastic sheet 205 is driven to raise and lower the fixing block 207, thereby adjusting the tightness between the support bar 201 and the fixing bar 202. After fixing one end of the warp and weft net, the fixing bar 202 is pulled by the pull ring 3, which in turn pulls the warp and weft net to unfold it. When the fixing bar 202 and the support bar 201 move, they will drive the belt ruler 209, so that the belt ruler 209 is released on the take-up drum 208, so that the length of the unfolded warp and weft net can be determined by the belt ruler 209.

[0024] Example 2, see Figures 1-4 Based on Embodiment 1, a rotating assembly 4 is provided on the outer surface of the take-up drum 208. The rotating assembly 4 includes a rotating rod 401, which is fixedly connected to the front of the take-up drum 208. The rotating rod 401 passes through two take-up drums 208. A rotating handle 402 is fixedly connected to the front and rear ends of the rotating rod 401, which can manually drive the rotating rod 401 to rotate. A housing 403 is rotatably connected to the outer surface of the rotating rod 401. A bearing is provided between the housing 403 and the rotating rod 401. The housing 403 is fixedly connected to the outer surface of the warp and weft wire mesh machine outlet 1. There are two housings 403, which are respectively provided on the front and back sides of the warp and weft wire mesh machine outlet 1. Two winding drums 208 and a belt ruler 209 are installed inside the housing 403. A drive assembly 5 is installed on the right side of the rotating rod 401. The drive assembly 5 includes a motor 501 with its output end facing rearward. The motor 501 is fixedly connected to the upper part of the discharge port 1 of the warp and weft wire mesh machine. The output end of the motor 501 is fixedly connected to a rotating shaft through a coupling, and a first gear 502 is fixedly connected to the rear end of the rotating shaft. A shaft bracket is provided on the outer surface of the rotating shaft to support the rotating shaft for stable rotation. The drive assembly 5 also includes a second gear 503, which is fixedly connected to the outer surface of the rotating rod 401. The second gear 503 meshes with the first gear 502 on the left side.

[0025] In practical use, when the warp and weft mesh is unfolded to a specific length, the warp and weft mesh is loosened by separating the support bar 201 and the fixing bar 202. At this time, rotating the handle 402 clockwise drives the rotating rod 401 to rotate, which in turn drives the winding drum 208 to rotate clockwise, thereby winding up the belt ruler 209. This allows the support bar 201 and the fixing bar 202 to return to their original positions close to the outlet 1 of the warp and weft mesh machine for the next unfolding. Starting the motor 501 drives the rotating shaft to rotate the first gear 502 counterclockwise. The rotation of the first gear 502 drives the second gear 503 to rotate clockwise, which in turn drives the rotating rod 401 to rotate the winding drum 208 clockwise, making winding and resetting easier.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
