When the mesh cloth contacts the detection structure during movement, the width of the mesh cloth is detected by the detection structure, so as to automatically adjust the spraying range of the adjustable spraying structure according to the width of the mesh cloth, without manual adjustment, so as to improve the production efficiency of spraying the base glue on the mesh cloth;

[0040] When the winding roller 3 moves to a certain position with the mesh cloth, the base glue is sprayed by the adjustable spraying structure. After the base glue spraying is completed, as the mesh cloth continues to move, the adjustable drying structure is used to dry the sprayed mesh cloth, thereby further improving the production efficiency of the mesh cloth;

When the hydraulic adjustment structure works, the corresponding sealing plate 11 is driven to move in the sealing groove 10. After the sealing plate 11 moves to a certain position, the opening 12 is connected to the liquid inlet channel, so as to automatically open the appropriate number of liquid inlet pipes 8 according to the width of the mesh cloth;

[0045] After the primer enters the connecting pipe 5 through the pipeline and the liquid inlet joint 6, the primer enters into the plurality of liquid inlet pipes 8. At the same time, as the primer moves, the primer enters into the adjusting pipe 9.

[0046] The overall stability of the connecting pipe 5 can be improved by relying on the second supporting rod 7 .

[0047] In order to automatically adjust the air outlet range of the air outlet plate 16 according to the width of the mesh cloth, for example, Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the present invention also includes that the adjustable drying structure includes an air outlet shell 14 with a downward opening, the upper part of the air outlet shell 14 is connected to an air inlet pipe 15, the bottom of the air outlet shell 14 is installed with an air outlet plate 16, and a plurality of groups of first air outlet holes 17 are distributed in an array on the air outlet plate 16, and a plurality of groups of horizontally arranged baffles 18 are arranged in the air outlet shell 14, and a plurality of groups of second air outlet holes 19 are arranged on the baffles 18, and the second air outlet holes 19 are staggered with the first air outlet holes 17 in the initial state, and the baffles 18 are located on the upper surface of the air outlet plate 16, and one end of the baffles 18 passes through the air outlet shell 14 and is slidably connected to the air outlet shell 14, and the number of the baffles 18 corresponds to the number of the regulating tubes 9;

Two groups of symmetrically arranged third support rods 20 are fixedly connected to the outer side of the air outlet shell 14, and the lower ends of the third support rods 20 are fixedly connected to the upper surface of the base 1.

[0049] When in use, when the mesh cloth contacts the detection structure, the width of the mesh cloth is detected by the detection structure, and the detection structure drives a suitable number of hydraulic adjustment structures to work. When the hydraulic adjustment structure works, the baffle 18 is driven to move. After the baffle 18 moves to a certain position, the second air outlet 19 on the baffle 18 corresponds to the first air outlet 17, and the mesh cloth is sprayed with primer by the nozzle 13. After the primer spraying is completed, as the winding roller 3 continues to drive the mesh cloth to move, the mesh cloth moves to a certain position, and the hot air is connected by the air inlet pipe 15. The gas enters the air outlet shell 14 through the air inlet pipe 15, and is discharged through the second air outlet 19 on the baffle 18 and the first air outlet 17 on the air outlet plate 16, so as to dry the mesh cloth, so as to automatically adjust the air outlet range of the air outlet plate 16 according to the width of the mesh cloth, so that the air outlet range of the air outlet plate 16 matches the width of the mesh cloth, and further improve the drying efficiency of the mesh cloth;

[0050] The overall stability of the air outlet housing 14 can be improved by relying on the third support rod 20 .

[0051] In order to adjust the spraying range and drying range according to the width of the mesh cloth, for example, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the present invention also includes that the extrusion detection includes a rotating shaft 21, and both ends of the rotating shaft 21 are rotatably connected to a fourth supporting rod 22 vertically arranged, and the lower end of the fourth supporting rod 22 is fixedly connected to the upper surface of the base 1;

[0053] When in use, one end of the mesh cloth is passed around several groups of extrusion rings 23 and then connected to the winding roller 3. The mesh cloth is driven to move by the rotation of the winding roller 3. The mesh cloth is squeezed and contacted with the extrusion ring 23, squeezing the first extrusion spring 24, thereby driving the extrusion ring 23 to move downward. When the extrusion ring 23 moves downward, it squeezes the corresponding first hydraulic telescopic rod 26, which is connected to the hydraulic adjustment structure by the first joint 27. When the corresponding first hydraulic telescopic rod 26 is squeezed, the corresponding hydraulic adjustment structure is driven, and the sealing plate 11 and the baffle 18 are driven to move by the hydraulic adjustment structure, so as to facilitate the adjustment of the spraying range and the drying range according to the width of the mesh cloth;

[0054] When the width of the mesh cloth is larger, the number of contacts between the mesh cloth and the extrusion ring 23 is also greater, and the extrusion ring 23 is driven to move downward at the same time, and the first hydraulic telescopic rod 26 is connected to the hydraulic adjustment structure, so that the spraying range of the adjustable spraying structure is larger, and the air outlet range of the adjustable drying structure is also larger; on the contrary, when the width of the mesh cloth is smaller, the number of contacts between the mesh cloth and the extrusion ring 23 is also smaller, and the extrusion ring 23 is driven to move downward at the same time, and the first hydraulic telescopic rod 26 is connected to the hydraulic adjustment structure, so that the spraying range of the adjustable spraying structure is smaller, and the air outlet range of the adjustable drying structure is also smaller, so that the spraying range and the drying range can be automatically adjusted according to the width of the mesh cloth, and the convenience of use and the production efficiency of the mesh cloth are further improved;

[0055] The fourth support rod 22 further improves the rotation stability of the rotating shaft 21 .

[0057] When in use, the first hydraulic telescopic rod 26 is squeezed and then drives the movable plate 29 to move in the fixed cylinder 28 through the first joint 27, the pipeline and the second joint 33. When the movable plate 29 moves, it squeezes the second squeezing spring 32, and at the same time, the first connecting rod 30 and the second connecting rod 31 are driven to move synchronously by the movable plate 29. When the first connecting rod 30 moves, it squeezes the sealing plate 11 and drives the sealing plate 11 to move, so that the opening 12 is connected with the liquid inlet channel. When the second connecting rod 31 moves, it drives the baffle 18 to move, so that the second air outlet 19 corresponds to the first air outlet 17, so as to facilitate the automatic adjustment of the spraying range and the drying range according to the width of the mesh cloth.

[0058] When one group of mesh cloth is sprayed, the extrusion ring 23 no longer moves downward, and the first extrusion spring 24 drives the extrusion ring 23 to reset and move, so that the extrusion ring 23 no longer squeezes the first hydraulic telescopic rod 26, and the second extrusion spring 32 drives the moving plate 29 to reset and move, so that the sealing plate 11 and the baffle 18 return to their initial state, so as to facilitate the spraying and drying of the next group of mesh cloth, and automatically adjust the spraying range and drying range according to the width of the next group of mesh cloth.

Specifically, since the air intake of the air outlet plate 16 is constant, the smaller the size of the mesh cloth, the smaller the air outlet area of ​​the air outlet plate 16, and the greater the wind force of the air outlet plate 16, thereby increasing the extrusion force of the air blowing plate on the squeezing plate 37. The greater the squeezing force on the squeezing plate 37, the greater the liquid supply of the second hydraulic telescopic rod 38, the greater the movement of the slide plate 43, and the smaller the overlapping area of ​​the connecting port 44 and the connecting channel 41, thereby reducing the liquid supply of the liquid pump 35; conversely, the larger the size of the mesh cloth, the smaller the wind force on the squeezing plate 37, the smaller the movement of the slide plate 43, and the smaller the overlapping area of ​​the connecting port 44 and the connecting channel 41, thereby increasing the liquid supply of the liquid pump 35;

[0065] In addition, the liquid supply of the liquid pump 35 can also be adjusted according to the mesh size of the mesh cloth. Specifically, when the mesh size of the mesh cloth is smaller, the wind force of the air outlet plate 16 after passing through the mesh cloth is smaller, thereby reducing the squeezing force on the squeezing plate 37. After driving the squeezing plate 37 to move downward, the second hydraulic telescopic rod 38 is squeezed. When the second hydraulic telescopic rod 38 is squeezed, it is connected to the piston cylinder 45 through a pipeline, driving the piston plate 46 and squeezing the return spring 48 and driving the return spring 48 to store force. When the piston plate 46 moves and drives the piston rod 47 to move, it drives the slide plate 43 to move synchronously. After the slide plate 43 moves, the connecting port 44 and the connecting channel 41 are partially staggered, thereby reducing The liquid output of the connecting channel 41 is further facilitated to automatically adjust the bottom glue liquid output of the fixed tube 40 according to the mesh size of the mesh cloth. When the mesh size is constant, the larger the mesh hole, the smaller the liquid supply of the liquid pump 35; on the contrary, when the mesh size of the mesh cloth is larger, the smaller the shielding effect of the mesh cloth on the air outlet of the air outlet plate 16 is. At this time, the greater the pressure of the air outlet plate 16 on the extrusion plate 37 after the air is discharged, the greater the movement of the slide plate 43, and the smaller the overlapping area of ​​the connecting port 44 and the connecting channel 41, thereby reducing the liquid supply of the liquid pump 35, thereby meeting the needs of mesh cloth processing, reducing resource waste, and improving production convenience;

[0066] When the second hydraulic telescopic rod 38 is no longer squeezed, the return spring 48 facilitates the piston plate 46 and the piston rod 47 to move to the initial state.

[0067] For example, Figure 2 As shown, the present invention also includes that a support roller 49 is provided above the base 1, and the support roller 49 is located between the first support rod 4 and the third support rod 20, and one end of the mesh cloth is connected to the winding roller 3 after bypassing the extrusion detection structure and the support roller 49.

[0068] When in use, the support roller 49 can improve the moving stability of the mesh cloth, and at the same time facilitate spraying and drying the mesh cloth.

[0069] When the present invention is in use, when it is necessary to spray the base glue on the mesh cloth, the mesh cloth is supported by the winding roller 3, one end of the mesh cloth is passed around a plurality of groups of extrusion rings 23 and then connected to the winding roller 3, and the mesh cloth is driven to move by the rotation of the winding roller 3, the mesh cloth is squeezed and contacted with the extrusion ring 23, and the first extrusion spring 24 is squeezed, thereby driving the extrusion ring 23 to move downward, and when the extrusion ring 23 moves downward, the corresponding first hydraulic telescopic rod 26 is squeezed, and after the first hydraulic telescopic rod 26 is squeezed, the moving plate 29 is driven to move in the fixed cylinder 28 through the first joint 27, the pipeline and the second joint 33, and when the moving plate 29 moves, the second extrusion spring 32 is squeezed, and at the same time, the first connecting rod 30 and the second connecting rod 31 are driven to move synchronously by the moving plate 29, When the first connecting rod 30 moves, it squeezes the sealing plate 11 and drives the sealing plate 11 to move, so that the opening 12 is connected with the liquid inlet channel, so as to automatically open a suitable number of liquid inlet pipes 8 according to the width of the mesh cloth. When the second connecting rod 31 moves, it drives the baffle plate 18 to move, so that the second air outlet hole 19 corresponds to the first air outlet hole 17, and the hot air is connected by the air inlet pipe 15. The gas enters the air outlet shell 14 through the air inlet pipe 15 and is discharged through the second air outlet hole 19 on the baffle plate 18 and the first air outlet hole 17 on the air outlet plate 16, so as to dry the mesh cloth, so as to automatically adjust the air outlet range of the air outlet plate 16 according to the width of the mesh cloth, and at the same time, the spraying range and the drying range can be automatically adjusted according to the width of the mesh cloth;

[0070] The liquid supply of the liquid pump 35 can be adjusted according to the size of the mesh cloth. Specifically, since the air intake of the air outlet plate 16 is constant, the smaller the size of the mesh cloth, the smaller the air outlet area of ​​the air outlet plate 16, and the greater the wind force of the air outlet plate 16, thereby increasing the extrusion force of the air blowing plate on the extrusion plate 37. The greater the extrusion force on the extrusion plate 37, the greater the liquid supply of the second hydraulic telescopic rod 38, the greater the movement of the slide plate 43, and the smaller the overlapping area of ​​the connecting port 44 and the connecting channel 41, thereby reducing the liquid supply of the liquid pump 35; conversely, the larger the size of the mesh cloth, the smaller the wind force on the extrusion plate 37, the smaller the movement of the slide plate 43, and the smaller the overlapping area of ​​the connecting port 44 and the connecting channel 41, thereby increasing the liquid supply of the liquid pump 35;

[0071] In addition, the liquid supply of the liquid pump 35 can also be adjusted according to the mesh size of the mesh cloth. Specifically, when the mesh size of the mesh cloth is smaller, the wind force of the air outlet plate 16 after passing through the mesh cloth is smaller, thereby reducing the squeezing force on the squeezing plate 37. After driving the squeezing plate 37 to move downward, the second hydraulic telescopic rod 38 is squeezed. When the second hydraulic telescopic rod 38 is squeezed, it is connected to the piston cylinder 45 through a pipeline, driving the piston plate 46 and squeezing the return spring 48 and driving the return spring 48 to store force. When the piston plate 46 moves and drives the piston rod 47 to move, it drives the slide plate 43 to move synchronously. After the slide plate 43 moves, the connecting port 44 and the connecting channel 41 are partially staggered, thereby reducing The liquid output of the connecting channel 41 further facilitates automatic adjustment of the bottom glue liquid output of the fixed tube 40 according to the mesh size of the mesh cloth. When the mesh size is constant, the larger the mesh holes, the smaller the liquid supply of the liquid pump 35. On the contrary, when the mesh size of the mesh cloth is larger, the smaller the shielding effect of the mesh cloth on the air outlet plate 16 is. At this time, the greater the pressure of the air outlet plate 16 on the extrusion plate 37 after the air is discharged, the greater the movement of the slide plate 43, and the smaller the overlapping area of ​​the connecting port 44 and the connecting channel 41, thereby reducing the liquid supply of the liquid pump 35, thereby meeting the needs of mesh cloth processing, reducing resource waste, and improving production convenience.
