[0026] like Figures 1 to 4 As shown, a fixing device for a mesh-pulling machine comprises a base 1, which is mounted on the upper surface of the mesh-pulling machine, a fixing mechanism 2 for limiting the moving range of the mesh at the upper end of the base 1 is mounted on the upper surface of the base 1, a positioning mechanism 5 is arranged on both the left and right sides of the fixing mechanism 2, a groove is arranged at the bottom of the inner wall of the fixing mechanism 2, and a lifting mechanism 4 is slidably connected inside the groove of the fixing mechanism 2; specifically, the mesh is clamped and positioned multiple times by starting the fixing mechanism 2, so as to avoid the subsequent movement of the mesh during the pulling process as much as possible, thereby improving the stability of the device in the process of positioning the mesh; the mesh is pre-positioned before being fixed by the fixing mechanism 2, so that the staff does not need to adjust the position of the mesh multiple times during the installation of the mesh, thereby improving the practicality of the device.

[0027] like Figure 1 , Figure 2 and Figure 4As shown, the fixing mechanism 2 includes a bottom plate 201, which is mounted on the upper surface of the base 1, an L-shaped fixing plate 205 is arranged on the back of the bottom plate 201, a hydraulic cylinder 206 is installed on the top of the inner wall of the L-shaped fixing plate 205, a top plate 203 is installed on the output end of the hydraulic cylinder 206, an arc-shaped limiting plate 204 is arranged on the lower surface of the top plate 203, a groove is provided on the upper surface of the bottom plate 201, and the position of the inner groove of the bottom plate 201 is located on the moving path of the arc-shaped limiting plate 204, a plurality of groups of positioning rods 202 are installed on the upper surface of the bottom plate 201, a plurality of groups of through holes are arranged on the upper surface of the top plate 203, and the positions of the plurality of groups of through holes in the top plate 203 are located at the upper ends of the plurality of groups of positioning rods 202;

[0028] Specifically, when the subsequent fixing mechanism 2 pulls up the mesh, the mesh is pulled to sleeve the multiple sets of holes at the corner of one end of the mesh on the outer surface of the multiple sets of positioning rods 202, and then the hydraulic cylinder 206 is started to push the top plate 203 to move, driving the arc-shaped limit plate 204 to push the mesh at the upper end of the bottom plate 201 to be clamped into the groove of the bottom plate 201, and the lower surface of the top plate 203 is abutted against the upper surface of the mesh sleeved on the outer surface of the multiple sets of positioning rods 202, so that the fixing mechanism 2 performs double-layer positioning on the mesh during use, thereby minimizing the friction between the mesh and the bottom plate 201. The mesh is prevented from moving during the subsequent pulling process, thereby improving the stability of the device in the process of positioning the mesh; the mesh is sleeved on the outer surface of multiple groups of positioning rods 202, so that multiple groups of positioning rods 202 can pre-position one end of the mesh during use, thereby minimizing the movement of the other end of the mesh when the subsequent arc-shaped limiting plate 204 pushes the mesh to be clamped in the groove of the bottom plate 201, causing the staff to adjust the position of the mesh multiple times during the installation of the mesh, thereby improving the practicality of the device.

[0029] like Figure 1 and Figure 2 As shown, the front and rear corners of the inner groove of the bottom plate 201 are both set as arc-shaped rounded corners; specifically, the front and rear corners of the inner groove of the bottom plate 201 are both set as arc-shaped rounded corners, so that when the subsequent arc-shaped limiting plate 204 pushes the mesh cloth into the groove of the bottom plate 201, the mesh cloth is not easily damaged by friction with the front and rear corners of the groove of the bottom plate 201, thereby minimizing the breakage of the subsequent mesh cloth after friction with the front and rear corners of the groove of the bottom plate 201, thereby improving the practicability of the device during use.

[0030] like Figure 1 and Figure 2As shown, a card slot is provided on the upper surface of the fixing mechanism 2, and a ceramic heating plate 3 is arranged inside the card slot of the fixing mechanism 2, and the ceramic heating plate 3 is located at the front side of the inner groove of the bottom plate 201; specifically, when the subsequent mesh cloth is pulled up, the ceramic heating plate 3 is started, and then the mesh cloth is pulled to move between the bottom plate 201 and the top plate 203, and the mesh cloth is tightly fitted on the upper surface of the ceramic heating plate 3 and moved, so that the ceramic heating plate 3 heats and shapes the mesh cloth during the movement of the subsequent mesh cloth, and then the wrinkled part of the subsequent mesh cloth can be shaped during the disassembly and movement process, thereby reducing the time spent on the subsequent mesh cloth in the production process, thereby expanding the function of the device during use, and thus improving the practicability of the device.

[0031] like Figure 2 and Figure 4 As shown, the two groups of positioning mechanisms 5 include fixed blocks 501, which are respectively installed on the left and right sides of the bottom plate 201, and the upper surfaces of the two groups of fixing blocks 501 are provided with fixed rods 503. The outer surfaces of the two groups of fixing rods 503 are slidably connected with connecting blocks 502, and the adjacent sides of the two groups of connecting blocks 502 are respectively installed on the left and right sides of the two groups of top plates 203; specifically, the fixed rods 503 are slidably connected to the inside of the connecting blocks 502, so that the positioning mechanism 5 limits the moving path of the top plate 203 at the upper end of the bottom plate 201, thereby avoiding the subsequent top plate 203 from being offset during the movement process and causing the hydraulic cylinder 206 to be bent; the moving position of the top plate 203 during use is limited by the two groups of positioning mechanisms 5, thereby avoiding the subsequent mesh cloth from causing the top plate 203 to be offset during the lifting process and causing the hydraulic cylinder 206 to be bent, thereby improving the service life of the hydraulic cylinder 206.

[0032] like Figures 2 to 4 As shown, the lifting mechanism 4 includes a fixed plate 401, a positioning groove is provided on the upper surface of the base plate 201, the fixed plate 401 is slidably connected to the inside of the positioning groove of the base plate 201, and a plurality of groups of positioning slots 403 are provided on the upper surface of the fixed plate 401, and the inner walls of the plurality of groups of positioning slots 403 are respectively abutted against the outer surfaces of the plurality of groups of positioning rods 202, and a handle 402 is installed on the left side of the fixed plate 401, and the upper surface of the fixed plate 401 and the upper surface of the base plate 201 remain parallel; specifically, when the subsequent mesh cloth is lifted, the fixed plate 401 is driven to slide on the outer ends of the plurality of groups of positioning rods 202 by pulling the handle 402, so that the subsequent fixed plate 401 drives the mesh cloth sleeved on the outer surfaces of the plurality of groups of positioning rods 202 to quickly move out of the outer surfaces of the plurality of groups of positioning rods 202 during the sliding process, thereby shortening the time consumed by the subsequent staff to disassemble and move the mesh cloth from the outer ends of the plurality of groups of positioning rods 202, thereby facilitating the subsequent staff to quickly replace the mesh cloth.

[0033] In summary: by pulling the mesh, multiple groups of holes at the corners of one end of the mesh are sleeved on the outer surfaces of multiple groups of positioning rods 202, and then by starting the hydraulic cylinder 206 to push the top plate 203 to move, the arc-shaped limit plate 204 is driven to push the mesh at the upper end of the bottom plate 201 to be clamped into the groove of the bottom plate 201, and the lower surface of the top plate 203 is abutted against the upper surface of the mesh sleeved on the outer surfaces of the multiple groups of positioning rods 202, so that the fixing mechanism 2 can perform double-layer positioning on the mesh during use, thereby minimizing the movement of the subsequent mesh during the pulling process; by sleeve-connecting the mesh on the outer surfaces of the multiple groups of positioning rods 202, the multiple groups of positioning rods 202 can pre-position one end of the mesh during use, thereby minimizing the movement of the other end of the mesh when the subsequent arc-shaped limit plate 204 pushes the mesh to be clamped in the groove of the bottom plate 201, which causes the staff to adjust the position of the mesh many times during the installation of the mesh.

[0034] At the same time, by starting the ceramic heating plate 3, and then pulling the mesh to move between the bottom plate 201 and the top plate 203, the mesh is closely attached to the upper surface of the ceramic heating plate 3 and moved, so that the ceramic heating plate 3 heats and shapes the mesh during the subsequent movement of the mesh, and then the wrinkled parts of the subsequent mesh can be shaped during the disassembly and movement, thereby reducing the time spent on the subsequent mesh in the production process; the fixing rod 503 is slidably connected to the inside of the connecting block 502, so that the positioning mechanism 5 is aligned with the top plate 203 The moving path of the upper end of the bottom plate 201 is restricted to avoid the subsequent top plate 203 from being offset during the movement and causing the hydraulic cylinder 206 to bend; the fixed plate 401 is driven to slide on the outer end of the multiple groups of positioning rods 202 by pulling the handle 402, so that the subsequent fixed plate 401 can drive the mesh cloth sleeved on the outer surface of the multiple groups of positioning rods 202 to quickly move out of the outer surface of the multiple groups of positioning rods 202 during the sliding process, thereby shortening the time spent by subsequent staff in removing and moving the mesh cloth from the outer end of the multiple groups of positioning rods 202.
