The textile substrate is wound on the winding roller and the unwinding roller. A gas-liquid mixing spraying device is provided above the textile substrate. The gas-liquid mixing spraying device is connected to the material source via a delivery pump. The main body of the gas-liquid mixing spraying device is connected to the compressed air source and the electrostatic generator, respectively. An electrode plate is provided below the textile substrate. A diffusion angle adjustment device is provided on the nozzle head of the gas-liquid mixing spraying device. However, the adjustment wall plate of the existing diffusion angle adjustment device is adjusted electrically or manually, requiring a separate electric or manual adjustment power source or manual operation. The adjustment angle cannot have multiple diffusion angle adjustment methods, resulting in low production efficiency and low raw material utilization of the electrostatic spraying device for textile substrates.

The compressed air source 6 is connected to the main body of the gas-liquid mixed spraying device 4 through a first pipeline 61. It is characterized in that the compressed air source 6 is also connected to the diffusion angle adjusting device 8 through a second pipeline 62. The diffusion angle adjusting device 8 is used to adjust the diffusion angle of the spray liquid of the nozzle head by changing the pressure of the gas.

[0029] The diffusion angle adjustment device 8 includes an outer wall plate 81, an inner wall plate (82, 83), and an elastic membrane bag (84, 85). The elastic membrane bag is arranged between the outer wall plate 81 and the inner wall plate. The elastic membrane bag is connected to the compressed air source 6 through a second pipeline 62. The elastic membrane bag is connected to the pressure relief valve through a pressure relief pipe. The diffusion angle adjustment device 8 is used to adjust the diffusion angle of the inner wall plate by changing the pressure of the gas in the elastic membrane bag, thereby adjusting the diffusion angle of the spray liquid of the nozzle head.

[0030] Furthermore, the inner wall plate (82, 83) includes a first inner wall plate 82 and a second inner wall plate 83. One end of the first inner wall plate 82 is connected to the main body of the diffusion angle adjustment device 8 through a hinge, and the second inner wall plate 83 is connected to the other end of the first inner wall plate 82 through a hinge. One end of the first inner wall plate 82 is connected to a second elastic member 87, and one end of the second inner wall plate 83 is connected to a first elastic member 86. A first elastic membrane bag 84 is arranged between the first inner wall plate 82 and the outer wall plate 81, and a second elastic membrane bag 85 is arranged between the second inner wall plate 83 and the outer wall plate 81. The two elastic membrane bags are arranged independently, and the elastic member is used to reset the elastic membrane bag when the pressure is released.

[0036] The present invention provides an electrostatic spraying device for a textile substrate. By configuring a diffusion angle adjustment device 8 as an elastic membrane capsule type, the pressure change of the gas is used to adjust the diffusion angle of the spray liquid of the nozzle head. There is no need to separately configure an electric or manual spray liquid diffusion angle adjustment device, and only the existing nearby compressed gas source 6 can be utilized. By configuring the elastic membrane capsule as an independent structure, the first elastic membrane capsule 84 and the second elastic membrane capsule 85 can be controlled separately, so that the inner wall plates (82, 83) of the diffusion angle adjustment device 8 can have multiple diffusion angle adjustment modes.

[0037] The diffusion angle adjustment device 8 is substantially conical in shape, and the cross section of the diffusion angle adjustment device 8 (outer wall plate 81 , inner wall plate) is substantially rectangular or circular.

[0038] A control method for an electrostatic spraying device for a textile substrate comprises the following steps:

[0039] Step S1: setting or selecting the winding speed and width of the textile substrate 3 through the controller 9;

[0040] Step S2: the controller 9 controls / opens the first regulating valve group 63 (including the first solenoid valve and the second solenoid valve) to inflate the first elastic membrane sac 84 and the second elastic membrane sac 85 separately, and the first inner wall plate 82 and / or the second inner wall plate 83 rotates, so that the inner wall plates (82, 83) of the diffusion angle adjustment device 8 have multiple diffusion angle adjustment modes;

[0041] Step S3: The controller 9 reduces / releases the pressure of the first elastic membrane bladder 84 and the second elastic membrane bladder 85 separately through the first pressure relief valve 641 and the second pressure relief valve 642 , thereby rotating the first inner wall plate 82 and / or the second inner wall plate 83 to a preset angle or resetting;

[0042] Step S4: The gas-liquid mixed spraying device 4 performs a spraying operation at a spray liquid diffusion angle that matches the winding speed and width of the textile substrate 3 .

[0043] The diffusion angle adjustment device 8 can be adjusted during the operation of the electrostatic spraying device, or when the electrostatic spraying device is on standby or stopped.

[0044] The present invention provides an electrostatic spraying device for a textile substrate, which improves the production efficiency of the electrostatic spraying device for the textile substrate and reduces the waste of raw materials by using a gas-liquid mixed spraying device 4 to perform a spraying operation at a spray liquid diffusion angle that matches the winding speed and width of the textile substrate 3.

[0045] The present invention discloses an electrostatic spraying device for textile substrates. The device utilizes a diffusion angle adjustment device 8 configured as an elastic membrane capsule and utilizes changes in gas pressure to adjust the diffusion angle of the spray liquid at the spray head. This eliminates the need for a separate electric or manual diffusion angle adjustment device, and utilizes an existing, nearby compressed gas source 6. By configuring the elastic membrane capsule as an independent structure, the volume changes of the first elastic membrane capsule 84 and the second elastic membrane capsule 85 can be independently controlled, thereby enabling the inner wall plates (82, 83) of the diffusion angle adjustment device 8 to have multiple diffusion angle adjustment modes. By enabling the gas-liquid hybrid spraying device 4 to perform a spraying operation at a diffusion angle of the spray liquid that matches the winding speed and width of the textile substrate 3, the production efficiency of the electrostatic spraying device for textile substrates can be improved, and raw material waste can be reduced.
