[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] In one embodiment of the present invention: The film coating apparatus 2 includes: a support 201 connected to a base 1; a top seat 202 connected to the end of the support 201 away from the base 1; at least two first driving members 203 connected to the support 201; a first connecting arm 204 connected to the first driving members 203; a second driving member 205 connected to the end of the first connecting arm 204 away from the first driving member 203; and an integrated coating roller 206 connected to the top seat 202.

Figure 1 As shown, the middle part of the PET film is in contact with the auxiliary tensioning device 5 and the integrated coating roller 206, and the movable side of the PET film is in contact with... Figure 1The right-side second drive component 205 is externally fixedly connected. The auxiliary tensioning device 5 can sense the pressure of the PET film material, and then calculate the tension of the PET film material at this time through the terminal device (not shown in the figure). When the PET film material is coated with colloid, the bonding ability between the colloid and the PET film material is optimal when the PET film material is within the optimal tension range. When both the left-side first drive component 203 and the right-side first drive component 203 rotate counterclockwise, in conjunction with the auxiliary tensioning device 5, the PET film material can be conveyed, and then the colloid is coated through the central integrated coating roller 206. The integrated coating roller 206 has a built-in glue replenishing component (not shown in the figure), which can complete the follow-up material replenishment of the coating roller. During the PET film material conveying process, the thickness of the PET film material outside the left-side second drive component 205 gradually decreases, and the right-side second drive component 205... 05. As the thickness of the outer PET film gradually increases, the first driving components 203 on both sides can drive the corresponding first connecting arms 204 to rotate in opposite directions based on the pressure changes sensed by the auxiliary tensioning device 5. At the same time, the auxiliary tensioning device 5 in the middle unfolds and adjusts accordingly, so that the conveyed PET film is always within the optimal tension range, thereby ensuring the bonding quality between the colloid and the PET film. The first driving component 203 is not limited to an electric shaft seat; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the rotation adjustment of the first connecting arm 204. No specific limitation is made here. The second driving component 205 is not limited to an electric roller; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the rotational conveying of the PET film. No specific limitation is made here.

[0016] In one embodiment of the present invention: like Figure 1 As shown, the pressurization device 3 includes: an air chamber 301 connected to the base 1; a blower 302 connected to the air chamber 301; the blower 302 is a blower; a first control element 303 connected to the air chamber 301; the first control element 303 is a solenoid valve; and at least two second control elements 304 connected to the air chamber 301; the second control elements 304 are solenoid valves. When the blower 302 is running, it can blow air into the air chamber 301. When the second control components 304 on both sides are closed and the first control component 303 is opened, all the blown air inside the air chamber 301 can enter the auxiliary tensioning device 5. When the second control components 304 on both sides are opened and the first control component 303 is closed, all the blown air inside the air chamber 301 enters the membrane heating device 7 and the colloid curing auxiliary device 8.

[0017] In one embodiment of the present invention: like Figures 1 to 3As shown, the transmission adjustment device 4 includes: a first connecting pipe 401, which is connected to a first control component 303; an air collecting chamber 402, which is connected to the end of the first connecting pipe 401 away from the first control component 303; at least two pressurizing chambers 403, which are disposed inside the air collecting chamber 402; a first elastic element 404, which is connected to the inside of the pressurizing chamber 403; the first elastic element 404 is a spring; a piston drive shaft bracket 405, which is connected to the first elastic element 404; and a connecting roller 406, which is rotatably connected to the side of the piston drive shaft bracket 405 away from the first elastic element 404. When the second control components 304 on both sides are closed and the first control component 303 is opened, all the gas inside the air chamber 301 enters the first connecting pipe 401. The gas is then introduced into the gas collection chamber 402 and the two pressurization chambers 403 through the connecting pipe 401, which drives the piston drive shaft frame 405 and the connecting roller 406 on both sides to move in opposite directions, thereby completing the deployment drive of the auxiliary tensioning device 5.

[0018] In one embodiment of the present invention: like Figure 1 As shown, the auxiliary tensioning device 5 includes: a second elastic element 501 connected to the base 1; the second elastic element 501 is selected as a spring bearing; at least two second connecting arms 502 connected to the second elastic element 501 and rollingly abutting against the connecting roller 406; a pressure sensing shaft 503 rotatably connected to the second connecting arms 502; and a transmission roller 504 fixedly connected to the pressure sensing shaft 503. When the connecting rollers 406 on both sides move in opposite directions, they can drive the second connecting arms 502 on both sides to rotate synchronously in opposite directions around the second elastic element 501. This, in conjunction with the second driving element 205 that adjusts the rotation on both sides, adjusts the tension of the PET film. Several pressure sensors (not shown in the figure) are installed in the gap between the transmission roller 504 and the pressure sensing shaft 503. While the pressure sensing shaft 503 and the transmission roller 504 are rotating, the PET film applies pressure to the transmission roller 504. The internal pressure sensors detect real-time pressure information, analyze and calculate it through the terminal device (not shown in the figure), and send a signal to control the second driving element 205 on both sides to rotate in opposite directions by a certain angle.

The distance between the heating trough frame 705 and the PET film is fixed to prevent the PET film from overheating. The fourth driving component 704 can adjust the angle of the heating trough frame 705 so that the heating trough frame 705 is adjusted to be parallel to the PET film on the left. When the first control component 303 is closed and the second control components 205 on both sides are opened, some of the blower gas enters the second connecting pipe 701 and is introduced into the heating trough frame 705 through the first connecting hose 702. After being heated by the heating component 706, it is directionally discharged through several troughs inside the heating trough frame 705, thereby achieving uniform preheating of the conveyed PET film and improving the bonding ability between the PET film and the colloid. In this application, the third driving component 703 is not limited to an electric telescopic rod; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the movement adjustment of the fourth driving component 704. No specific limitation is made here.

Once the conveying angle of the PET film on the right side is determined, the fifth driving component 803 can adjust the distance between the cooling tank frame 805 and the PET film, and the fourth driving component 704 can adjust the angle of the cooling tank frame 805 so that the cooling tank frame 805 is adjusted to be parallel to the PET film on the right side. When the first control component 303 is closed and the second control components 205 on both sides are opened, some of the blower gas enters the interior of the third connecting pipe 801, and is introduced into the interior of the cooling tank frame 805 through the second connecting hose 802. It is then discharged directionally through several tanks inside the cooling tank frame 805, thereby achieving blower cooling of the colloid coated on the outside of the PET film and accelerating the solidification of the colloid. In this application, the fifth driving component 803 is not limited to an electric telescopic rod; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the movement adjustment of the sixth driving component 804.

After the coated PET film is cured by the air blower in the cooling tank 805, it is introduced into the UV curing chamber 9 for UV curing, which further accelerates the curing speed and quality of the colloid.

[0022] The working principle of this invention is: PET film is wound and packaged in... Figure 1 The outer side of the second drive unit 205 on the left, with PET film material as shown. Figure 1As shown, the middle part of the PET film is in contact with the auxiliary tensioning device 5 and the integrated coating roller 206, and the movable side of the PET film is in contact with... Figure 1 The right-side second drive component 205 is externally fixedly connected. The auxiliary tensioning device 5 can sense the pressure of the PET film material, and then calculate the tension of the PET film material at this time through the terminal device (not shown in the figure). When the PET film material is coated with colloid, the bonding ability between the colloid and the PET film material is optimal when the PET film material is within the optimal tension range. When both the left-side first drive component 203 and the right-side first drive component 203 rotate counterclockwise, in conjunction with the auxiliary tensioning device 5, the PET film material can be conveyed, and then the colloid is coated through the central integrated coating roller 206. The integrated coating roller 206 has a built-in glue replenishing component (not shown in the figure), which can complete the follow-up material replenishment of the coating roller. During the PET film material conveying process, the thickness of the PET film material outside the left-side second drive component 205 gradually decreases, and the right-side second drive component 205... 05. As the thickness of the outer PET film gradually increases, the first driving components 203 on both sides can drive the corresponding first connecting arms 204 to rotate in opposite directions based on the pressure changes sensed by the auxiliary tensioning device 5. At the same time, the auxiliary tensioning device 5 in the middle unfolds and adjusts accordingly, so that the conveyed PET film is always within the optimal tension range, thereby ensuring the bonding quality between the colloid and the PET film. The first driving component 203 is not limited to an electric shaft seat; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the rotation adjustment of the first connecting arm 204. No specific limitation is made here.

When the second control components 304 on both sides are closed and the first control component 303 is open, all the blown air inside the air chamber 301 can enter the auxiliary tensioning device 5. When the second control components 304 on both sides are open and the first control component 303 is closed, all the blown air inside the air chamber 301 enters the membrane heating device 7 and the colloid curing auxiliary device 8. When the second control components 304 on both sides are closed and the first control component 303 is open, all the air inside the air chamber 301 enters the first connecting pipe 401. Through the connecting pipe 401, the air is introduced into the gas collecting chamber 402 and the two pressurizing chambers 403, driving the piston drive shafts 405 and connecting rollers 406 on both sides to move in opposite directions, thereby completing the deployment drive of the auxiliary tensioning device 5. When the connecting rollers 406 on both sides move in opposite directions, they can drive the second connecting arms 5 on both sides. 02. With the second elastic element 501 as the axis, it rotates synchronously in opposite directions, and then cooperates with the second drive element 205 on both sides to adjust the tension of the conveyed PET film. Several pressure sensors (not shown in the figure) are installed in the gap between the transmission roller 504 and the pressure sensing shaft 503. While the pressure sensing shaft 503 and the transmission roller 504 are rotating, the PET film gives pressure to the transmission roller 504. The internal pressure sensors sense the real-time pressure information, analyze and calculate through the terminal device (not shown in the figure) and send a signal to control the second drive element 205 on both sides to rotate in opposite directions by a certain angle. At the same time, the second control element 304 on both sides is closed, and the first control element 303 is opened and closed at timed intervals. All the blower gas enters the first connecting pipe 401. The second connecting arms 502 on both sides also rotate and adjust by a certain angle, thereby realizing that the PET film is in the optimal tension state.

[0024] Once the conveying angle of the PET film on the left is determined, the third drive component 703 can adjust the distance between the heating tray 705 and the PET film. This distance is fixed to prevent overheating of the PET film. The fourth drive component 704 can adjust the angle of the heating tray 705, ensuring it is parallel to the PET film on the left. When the first control component 303 is closed and the second control components 205 on both sides are open, some of the forced-air gas enters the second connecting pipe 701 and is guided into the heating tray 705 through the first connecting hose 702. After being heated by the heating element 706... The heating trough 705 is oriented through several grooves inside, which can uniformly preheat the conveyed PET film and improve the bonding ability between the PET film and the colloid. The third driving component 703 is not limited to an electric telescopic rod; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the movement and adjustment of the fourth driving component 704. No specific limitation is made here. The fourth driving component 704 is not limited to an electric shaft seat; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the rotation and adjustment of the heating trough 705. No specific limitation is made here.

[0025] Once the conveying angle of the PET film on the right side is determined, the fifth driving component 803 can adjust the distance between the cooling tray 805 and the PET film, and the fourth driving component 704 can adjust the angle of the cooling tray 805, so that the cooling tray 805 is adjusted to be parallel to the PET film on the right side. When the first control component 303 is closed and the second control components 205 on both sides are opened, some of the blown air enters the third connecting pipe 801, and is introduced into the cooling tray 805 through the second connecting hose 802. It is then directionally discharged through several tanks inside the cooling tray 805, realizing the blown air cooling of the colloid coated on the outside of the PET film, accelerating the solidification of the colloid. The actuator 803 is not limited to an electric telescopic rod; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, as long as it can achieve the movement and adjustment of the sixth driving component 804. No specific limitation is made here. The sixth driving component 804 is not limited to an electric shaft seat; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, as long as it can achieve the rotation and adjustment of the cooling tank frame 805. No specific limitation is made here. After the coated PET film is cured by the air blower of the cooling tank frame 805, it is introduced into the UV curing chamber 9 for UV curing, which further accelerates the curing speed and quality of the colloid.

[0026] In summary, the film coating device 3 and the auxiliary tensioning device 5 of this equipment can sense the force information of the film in real time and adjust accordingly to keep the film in the optimal tension state. At the same time, the pressurizing device 3, together with the coating auxiliary device 6, can realize the preheating of the film and the curing of the colloid by blowing air, which further improves the processing quality of PET film.
