In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0025] First embodiment: See also Figure 1~Figure 5The present invention provides an adjustable thin film dry composite device, including a base 101, a support box 102, a winding structure 103, a heating plate 104, an air pump 105, a guide channel 106, two air outlet plates 107 and a pressing structure 108, wherein the support box 102 is fixedly connected to the base 101 and is located on the top of the base 101, the winding structure 103 is arranged on the support box 102, the pressing structure 108 is arranged in the support box 102, the air outlet plate 107 has a plurality of air outlet holes, the two air outlet plates 107 are arranged on both sides of the pressing structure 108, the guide channel 106 is connected to the two air outlet plates 107, the air pump 105 is communicated with the guide channel 106, and the heating plate 104 is arranged on one side of the air pump 105.

[0026] In this embodiment, the base 101 serves as the basic support structure of the entire device, and it provides a stable installation platform for all upper components. The design of the base 101 takes into account the load-bearing capacity and stability, ensuring that the structure can remain stable even under long-term operation. The support box 102 is fixedly connected to the base 101 and is located on its top. The support box 102 serves to carry other components. The winding structure 103 is installed on the support box 102, and is mainly used to handle film materials entering and leaving the composite process. This includes the unfolding of the feed end and the collection of the finished product end, ensuring that the material can pass smoothly through the entire system without distortion or damage.

[0027] The pressing structure 108 is placed inside the support box 102 and is the key part to achieve close bonding between the films. By applying appropriate pressure, the film materials to be composited are brought into close contact, and the bonding process is completed under the heat provided by the heating plate 104. There is one air outlet plate 107 on each side, with multiple small holes (i.e., air outlet holes) distributed on it. These air outlet plates 107 are connected to the guide channel 106. When the air pump 105 is working, the air is discharged through the guide channel 106 and through these holes, so that the film can be evenly heated on both sides. The guide channel 106 connects the two air outlet plates 107 and is connected to the air pump 105. Its main responsibility is to guide the air flow from the air pump 105 to the air outlet plate 107 to ensure that the gas can be evenly distributed throughout the working area. The air pump 105 generates and delivers compressed air to the guide channel 106. The selection of the air pump 105 needs to take into account factors such as flow rate and pressure to meet the needs of specific application scenarios. The heating plate 104 is arranged on one side of the air pump 105, and is responsible for providing necessary heat to the passing film, promoting the activation of glue or other adhesives, thereby enhancing the bonding effect between different layers. The heating temperature can be adjusted according to actual needs to adapt to the thermal sensitivity of different materials.

[0028] The above structure can better conduct gas heat evenly on both sides of the film, so that the temperature on both sides tends to be consistent during pressing, which is efficient and energy-saving and can improve production quality.

[0029] The pressing structure 108 includes two adjusting blocks 109, an adjusting screw 110 and two pressing rollers 111. The two adjusting blocks 109 are slidably arranged in the supporting box 102, and the two pressing rollers 111 are rotatably arranged on the two adjusting blocks 109. The adjusting screw 110 has two opposite sections of threads, and the adjusting screw 110 is threadedly connected to the two adjusting blocks 109.

[0030] Two adjustment blocks 109 can slide inside the support box 102, and their function is to adjust the distance between the lamination rollers 111, so as to adapt to materials of different thicknesses or types. This adjustability is very important for ensuring the best lamination effect.

[0031] The adjusting screw 110 is a special screw with two sections of threads in opposite directions, one end of which is connected to one adjusting block 109, and the other end is connected to another adjusting block 109. By rotating the adjusting screw 110, the two adjusting blocks 109 can be pushed or pulled together synchronously, thereby changing the distance between the laminating rollers 111. This design allows the operator to easily adjust the laminating pressure and position as needed.

[0032] Two lamination rollers 111 are mounted on two adjustment blocks 109 and can rotate freely on the adjustment blocks 109. When the film passes, the two lamination rollers 111 will apply appropriate pressure to promote the close bonding between the film layers. The surface of the lamination roller 111 is usually specially treated to increase friction and reduce material damage. The air outlet plate 107 includes an air outlet plate body 112, a connecting block 113, a rotating rod 114 and an adjuster 115. The rotating rod 114 is rotatably connected to the adjustment block 109, the air outlet plate body 112 is rotatably set on the rotating rod 114, the connecting block 113 is connected to the air outlet plate body 112, and the adjuster 115 is used to push the connecting block 113 to adjust the position of the air outlet plate body. The air outlet plate body 112 is the part that directly contacts the film, and is covered with tiny air outlet holes for releasing air for heat conduction.

[0033] The connecting block 113 serves as an intermediate piece. On the one hand, it is fixedly connected to the air outlet plate body 112 . On the other hand, it allows the air outlet plate body 112 to be adjusted at a certain angle relative to the rotating rod 114 .

[0034] One end of the rotating rod 114 is connected to the adjusting block 109 so that the upper and lower positions can be adjusted together with the adjusting block 109, and the other end supports the outlet plate body 112 and its connecting block 113. The design of the rotating rod 114 enables the entire outlet plate 107 assembly to rotate around the adjusting block 109 to further adjust the left and right positions.

[0035] The regulator 115 controls the left and right position adjustment of the air outlet plate 107. The regulator 115 includes a push rod 116, a push screw 117 and a push motor 118. The push rod 116 has a connection groove. The push rod 116 is slidably arranged in the support box 102. The connection block 113 is slidably arranged in the connection groove of the push rod 116. The push screw 117 is threadedly connected to the push rod 116. The output end of the push motor 118 is fixedly connected to the push screw 117.

[0036] The push rod 116 has a connecting groove and can slide in the supporting box 102. The push rod 116 provides a basic movement path for the connecting block 113.

[0037] The push screw 117 and the push rod 116 form a threaded fit, and when rotating, the push rod 116 can be driven to move forward or backward.

[0038] The driving motor 118 provides a power source, and its output end is fixedly connected to the driving screw 117, and the precise position control of the push rod 116 is realized by controlling the forward and reverse rotation of the motor. Thus, the connecting block 113 can slide up and down in the connecting groove of the push rod 116 to further adjust the position of the adjusting block 109, so that the outlet plate body 112 can better fit the position of the film.

[0039] The adjustable film dry composite device further comprises an air guide plate, which is arranged on one side of the outlet plate body 112. The air guide plate is used to guide the discharged hot gas along the film, so as to preheat the film that is about to enter the outlet plate body 112, thereby improving the energy utilization rate.

[0040] The air guide plate includes a plate body 119, a rotating shaft 120, a driven roller 121 and a supporting spring 122. The rotating shaft 120 is rotatably set on the air outlet plate body 112, the plate body 119 is fixed to the rotating shaft 120, the driven roller 121 is set on one side of the plate body 119 for contacting the film, and the supporting spring 122 is used to support the plate body 119.

[0041] The plate body 119 is the main part of the air guide plate, which is fixedly mounted on the rotating shaft 120 and can adjust its angle as the rotating shaft 120 rotates. The design of the plate body 119 needs to consider the balance between lightness and strength to ensure reliability and durability under long-term operation.

[0042] The rotating shaft 120 is a key component connecting the outlet plate body 112 and the air guide plate, which allows the plate body 119 to rotate within a certain range around its central axis. This flexibility is essential for adapting to materials of different thicknesses or types, because the airflow distribution can be optimized by adjusting the angle of the plate body 119.

[0043] The driven roller 121 is disposed on one side of the plate 119 and directly contacts the passing film. The driven roller 121 helps maintain the flatness of the film surface without hindering the normal movement of the film. At the same time, it also helps to reduce friction and avoid unnecessary damage to the film.

[0044] Support springs 122 are installed under the plate 119 or at other appropriate positions to provide the necessary support force so that the plate 119 can be stably maintained in a predetermined working position. When encountering thicker materials or materials with special requirements, the support springs 122 can also play a buffering role to ensure the stability of the system operation.

[0045] The air guide plate further includes two L-shaped side plates 123 and a locking block 124 . The two L-shaped side plates 123 are slidably disposed on both sides of the plate body 119 , and the locking block 124 is disposed on the L-shaped side plates 123 .

[0046] Two L-shaped side plates 123 are slidably mounted on both sides of the plate body 119 , which not only increase the rigidity of the overall structure, but also, when used in conjunction with the locking block 124 , can achieve fine adjustment of the width direction of the air guide plate, thereby being suitable for films of different widths.

[0047] The locking block 124 is arranged on the L-shaped side plate 123 to fix the position of the side plate. The operator can adjust the L-shaped side plate 123 to a suitable position as required, and then lock it with the locking block 124, thereby ensuring the stability of the entire air guide plate structure. This design ensures both the flexibility of adjustment and the safety of use.

[0048] In summary, as an important component of the adjustable thin film dry composite device, the air guide plate provides strong support for improving the composite quality and ensuring the smooth progress of the production process through its unique structural design and effective cooperation with other components such as the air outlet plate 107.

[0049] The adjustable thin film dry composite device also includes an infrared detector 125, a heating area identification unit 126 and a control unit 127. The infrared detector 125 is used to obtain an infrared image of the pressing area; the heating area identification unit 126 is used to identify the thin film area in the infrared image; the control unit 127 is used to control the power of the heating plate 104 based on the temperature of the thin film area.

[0050] The infrared detector 125 is a non-contact temperature measurement device that captures the infrared radiation emitted by the material surface in the lamination area to obtain the thermal distribution image of the area. The infrared detector 125 can monitor the temperature changes in the entire lamination process in real time, providing accurate basic information for subsequent data analysis. It has the characteristics of high sensitivity and fast response, and can maintain good performance even under high-speed operation conditions.

[0051] The heating area identification unit 126 processes the data collected by the infrared detector 125 and identifies the film area actually involved in the heating. Using image processing techniques, such as edge detection, threshold segmentation and other methods, the heating area identification unit 126 can accurately locate the position and boundary of the film to be laminated. This step is crucial to achieve local precision heating, because different types of films may require different heating conditions to achieve the ideal bonding effect.

[0052] The control unit 127 dynamically adjusts the working state of the heating plate 104 according to the information received from the heating area identification unit 126. Specifically, when it is detected that the temperature of a certain part is lower than the set value, the control unit 127 will automatically increase the power output of the heating plate 104 in the corresponding area; otherwise, the power will be reduced or the heating will be stopped, so as to maintain the temperature in the entire lamination area uniform and meet the process requirements. In addition, the control unit 127 can also be linked with other systems (such as the air pump 105, the lamination structure 108, etc.) to ensure the coordination of the entire lamination process.

[0053] The adjustable thin film dry composite device also includes a circulation fan 128 and an air duct 129 . The air duct 129 is located near the air inlet of the heating plate 104 . The circulation fan 128 is connected to the air duct 129 and is located on one side of the plate body 119 .

[0054] The air with a certain amount of heat discharged from one side of the plate body 119 can be guided to one side of the air inlet of the heating plate 104 through the air duct 129 via the circulation fan 128, so that the incoming temperature has a certain initial temperature, thereby further improving the energy utilization rate.

[0055] Second embodiment: See also Figure 6 The present invention also provides an adjustable thin film dry composite method, comprising: S201: Put the film to be laminated into the support box 102 and pass it through the pressing structure 108; First, prepare the film material to be laminated, and select the appropriate film type and specifications according to actual needs. Introduce one end of the film material from one side of the support box 102 to ensure that it enters the device smoothly. The film should pass through the lamination structure 108 correctly to facilitate subsequent operations. Use the adjustment block 109 and the adjustment screw 110 to adjust the distance between the lamination rollers 111 to adapt to film materials of different thicknesses or types. At the same time, make sure that the film remains straight throughout the entire transmission path to avoid wrinkles or deviations.

[0056] S202 starts the heating plate 104, and drives the gas through the guide channel 106 into the gas outlet plate 107 through the air pump 105; Turn on the heating plate 104 and set the appropriate heating temperature. The heating plate 104 will gradually heat up to the preset value to provide the necessary heat for the subsequent pressing process. Activate the air pump 105 so that the compressed air flows along the guide channel 106 and finally reaches the air outlet plates 107 on both sides. The working pressure and flow rate of the air pump 105 need to be adjusted according to the specific process requirements. After passing through the guide channel 106, the gas is evenly distributed to each air outlet to evenly heat the film.

[0057] S203 The air outlet plates 107 on both sides heat both sides of the film to be laminated at the same time to reach the pressing temperature; When the film passes through the air outlet plate 107, the hot air from the air outlet plate 107 heats both sides of the film synchronously. This process ensures that all parts of the film can quickly and evenly reach the ideal lamination temperature. The infrared detector 125 is used to monitor the temperature distribution on the film surface in real time to ensure the temperature consistency in the entire area. If it is found that the local temperature is too high or too low, the power output of the heating plate 104 can be adjusted in time through the control system.

[0058] S204 The film is laminated by the laminating structure 108 and rolled up by the rolling structure 103 .

[0059] The heated film continues to move forward and enters the lamination structure 108 composed of two lamination rollers 111. During this process, the lamination roller 111 applies appropriate pressure to make the multi-layer film fit tightly and complete the bonding. After the lamination is completed, a visual inspection system or other quality inspection means can be set up to make a preliminary assessment of the quality of the composite film, such as checking whether there are defects such as bubbles and non-bonding. Finally, the composite film is neatly wound up by the winding structure 103 for subsequent storage or further processing. The winding speed and tension should be reasonably set according to the actual situation to ensure the flatness and integrity of the finished product.

[0060] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
