[0023] Embodiment 1:

[0024] This embodiment provides a film material wrinkle removal device, as Figure 1 shown, including a gas supply device, a blowing device 1, a fixed bracket 2 and a slider 3. The gas supply device is connected to the blowing device 1 and is used to provide wrinkle removal air flow for the blowing device 1; the blowing device 1 is installed on the slider 3 and is used to output wrinkle removal air flow to the film material 7 for blowing and wrinkle removal; the slider 3 is slidably connected to the fixed bracket 2 and is used to drive the blowing device 1 to move along the film surface extension direction of the film material 7.

[0025] As Figure 2 shown, it is an axial cross-sectional schematic diagram of transporting the film material 7 in actual production. The place where the transport roller 6 contacts the film material 7 is a straight line parallel to the axis of the transport roller 6. When transporting the optical film material 7, the film material 7 rolls along the rotation direction of the roller. Since the optical film material 7 will carry out the liquid medicine after being soaked in the liquid medicine, resulting in the surface of the transport roller 6 being wet, relative sliding occurs between the transport roller 6 and the optical film material 7. Therefore, the film material 7 may undergo side contraction in the width direction during the transmission process and generate wrinkles.

[0026] During use, as Figure 1 shown, the fixed bracket 2 is arranged above the film material 7 that has been soaked and dyed. The slider 3 is moved according to the width of the film material 7 and the position of the wrinkle 5, so that the connected blowing device 1 is moved to the side part of the film material 7 where wrinkles 5 are likely to occur or the part of the film material 7 where wrinkles 5 occur at other positions, and the blowing device 1 is adjusted to keep a certain distance from the surface of the film material 7. The gas supply device is turned on to ensure that the air flow provided by the gas supply device evenly blows towards the surface of the film material 7, thereby eliminating the wrinkles 5.

[0027] The blowing device 1 moves along the film surface extension direction of the film material 7 by means of the slider 3. The slider 3 is moved corresponding to the width of the film surface and the position of the wrinkle 5 to adjust the position of the blowing device 1, making the device easier to deal with film materials 7 of different sizes and shapes; the air flow of the blowing device 1 is used to remove wrinkles from the film material 7, avoiding the friction and damage caused by physical contact, and precisely dealing with the local wrinkles 5 of the film material 7 without affecting other parts of the film material 7. This design improves the operation accuracy, effectively removes wrinkles, and ensures the flatness and quality of the film material 7.

[0028] Embodiment 2:

[0029] This embodiment is an improvement based on Embodiment 1 and specifically includes the following points:

[0030] Optionally, at least two blowing devices 1 are provided, which are respectively located on both sides of the film material 7 and are used to blow air to remove wrinkles on the side edges of the film material 7. This configuration can more effectively handle the wrinkle 5 problem at the edge of the film material 7 and ensure the overall flatness of the film material 7.

[0031] The air supply device can select a CDA (Clean Dry Air) gas supply device, which includes an air compressor, a filter, a dryer, and a gas storage tank, to provide a clean and dry air flow, avoiding the pollution and moisture problems that may be brought by ordinary gases, and improving the wrinkle removal effect and the quality of the film material.

[0032] Optionally, the sliding connection between the slider 3 and the fixed bracket 2 is realized through the slide rail 4. The fixed bracket 2 is provided with a slide rail 4 arranged along the width direction of the film material 7, and the slider 3 is slidably connected through the slide rail 4, realizing the precise movement of the blowing device 1 in the width direction of the film material 7, and further improving the coverage range and effect of wrinkle removal. The slide rail 4 can use a special linear guide rail, fix the guide rail on the fixed bracket 2 through screws or clamps, and set multiple balls or rollers inside the slider 3 to make the slider 3 move along the guide rail with less friction. It is also possible to realize the sliding connection between the slider 3 and the fixed bracket 2 through a roller slideway, fix the rollers on the slider 3, connect the rollers to the slider 3 through bearings, ensure the smoothness and low friction during rolling, and use a cylindrical rod-shaped fixed bracket 2 as the track, and the rollers directly roll on its surface.

[0033] The blowing device 1 includes a blowing port 11, an angle-adjustable hard pipe 12, and a telescopic hose 13. The blowing port 11 is connected to the angle-adjustable hard pipe 12, and the hard pipe is connected to the air supply device through the telescopic hose 13. The angle-adjustable hard pipe 12 can select SUS304 material, which is corrosion-resistant and not easily deformed; the telescopic hose 13 can select an elastic plastic hose. This design enables the angle and position of the blowing device 1 to be adjusted according to actual needs, greatly increasing the flexibility. The blowing device 1 is fixed on the slider 3, that is, the telescopic hose 13 and the angle-adjustable hard pipe 12 are connected and communicated through the slider 3. In order to enable the steel hard pipe made of SUS304 material to have the angle adjustment ability while maintaining communication, a universal joint or a spherical joint can be installed between the slider 3 and the steel hard pipe. By adopting this joint, the steel hard pipe can rotate and tilt freely while being connected, adjusting the angle. Optionally, a rotary joint can also be installed at the connection between the telescopic hose 13 and the steel hard pipe made of SUS304 material, and the rotary joint can realize the rotation of the hard pipe around the connection axis while maintaining connectivity.

[0034] The air blowing device 1 is equipped with a pressure gauge and a regulating valve 14. The pressure gauge includes an electronic pressure gauge and / or a mechanical pressure gauge, and a display interface is provided on the fixed bracket 2 for displaying the air blowing pressure. The pressure gauge is signal-connected to the host computer, realizing real-time monitoring and adjustment of the air blowing pressure, and ensuring the stability and reliability of the wrinkle removal process.

[0035] The electronic pressure gauge can be an electronic pressure gauge with a standard communication interface. Connect the communication interface of the electronic pressure gauge to the host computer through the corresponding cable. Or an electronic pressure gauge supporting wireless communication technology can be selected, such as a pressure gauge with Wi-Fi, Bluetooth or Zigbee functions, and wirelessly pair the electronic pressure gauge with the host computer. The mechanical pressure gauge can combine a pressure sensor and a data acquisition system to transmit relevant pressure data to the host computer. The measuring component of the mechanical pressure gauge is used in combination with the pressure sensor. The pressure sensor will convert the pressure into an electrical signal, and then these signals are transmitted to the host computer through the data acquisition system for processing and display. Or a mechanical pressure gauge equipped with an electric converter can be selected. The electric converter can convert the mechanical reading into an electrical signal. Connect the output interface of the electric converter to the data interface of the host computer, and transmit the pressure data to the host computer through the electric converter.

[0036] The air blowing port 11 is designed in a conical shape, optimizing the jet effect of the air flow, making the air flow more concentrated and uniform, and improving the wrinkle removal efficiency.

[0037] During use, the fixed bracket 2 is arranged above the membrane material 7 that has been soaked and dyed. Move the slider 3 according to the width of the membrane material 7 and the position of the wrinkles 5. After the slider 3 drives the angle-adjustable rigid tube 12 to a suitable position, adjust the angle of the angle-adjustable rigid tube 12 so that the air blowing head is aligned with the surface of the wrinkled membrane material 7. According to the size of the membrane material 7 and the degree of shaking of the membrane material 7 during the air blowing process, adjust the regulating valve 14 to control the pressure of the air flow output by the CDA gas supply device. At the same time, record the improvement effect of different air blowing angles and air blowing pressures on the wrinkles of the membrane material 7 based on the data displayed by the pressure gauge. The host computer conducts real-time monitoring and data recording through the display interface and software to ensure the stability and effectiveness of the air blowing process.
