Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present invention: a drying device for a film laminating machine, including a heat-insulating outer frame 1, a lifting and drying body 2, an electric push rod 3, a support base 4, and a fixing bracket 5. A PLC controller 6 is provided on the fixing bracket 5. Support holes 8 are evenly and symmetrically penetrated through both sides of the heat-insulating outer frame 1. A support insertion rod 11 is movably inserted inside the support holes 8. Heat-insulating plug covers 7 are evenly and symmetrically rotatably connected to both sides of the heat-insulating outer frame 1. Temperature sensors 9 are symmetrically and evenly fixedly installed on both sides inside the heat-insulating outer frame 1. Conveyor turning rollers 10 are rotatably connected to both ends of the support base 4. A support connection frame 12 is fixedly connected to the top end of the lifting and drying body 2. Lifting brackets 14 are symmetrically and fixedly connected to both ends of the top end of the support connection frame 12. An isolation frame 13 is fixedly installed inside the bottom end of the lifting and drying body 2. Heat dissipation fans 15 are evenly fixedly installed at the bottom end of the isolation frame 13. A heater 16 is fixedly installed inside the bottom end of the lifting and drying body 2. Both sides of the lifting and drying body 2 are slidably connected inside the heat-insulating outer frame 1.

[0023] The PLC controller 6 is respectively wired and electrically connected to the electric push rod 3, the temperature sensor 9, the heat dissipation fan 15, and the heater 16. By combining the PLC controller 6 with the temperature sensor 9 and the heater 16, the temperature range can be automatically controlled, and the temperature can be adjusted according to the preset specifications, so as to achieve the stability of the drying temperature.

[0024] The electric push rods 3 are symmetrically and fixedly installed at both ends of the heat-insulating outer frame 1, and the telescopic ends of the electric push rods 3 are fixedly connected to the lifting brackets 14. By the telescopic movement of the electric push rods 3, the lifting brackets 14 move up and down. The movement of the lifting brackets 14 drives the support connection frame 12 to move, thereby driving the lifting and drying body 2 to move up and down to adjust the height between the heater 16 and the film-laminated article, and further adjusting the temperature of the hot air blown onto the surface of the film-laminated article.

[0025] The heat-insulating plug covers 7 correspond to the support holes 8, and the heat-insulating plug covers 7 are located outside the support holes 8. The heat-insulating plug covers 7 can close the support holes 8 to prevent the hot air inside the heat-insulating outer frame 1 from diffusing outward and increasing losses.

[0026] The two sides of the bottom end of the heat-insulating outer frame 1 are respectively fixedly installed on both sides of the support base 4, and the heat-insulating outer frame 1 is located at the top of the support base 4. Conveyor grooves are provided at both ends of the bottom end of the heat-insulating outer frame 1. Through the enclosure of the heat-insulating outer frame 1 and the support base 4, the hot air inside the heat-insulating outer frame 1 can circulate, and the conveyor grooves at both ends of the heat-insulating outer frame 1 are convenient for transporting the film-coated articles.

[0027] Hole grooves matching the support insertion rods 11 are evenly provided on the support connection frame 12. When the support insertion rods 11 are inserted inside the support holes 8 and pass through the hole grooves on the support connection frame 12 at the same time, the weight of the lifting and drying body 2 can be dispersed on the heat-insulating outer frame 1, thereby reducing the stress on the electric push rod 3 and the stress at both ends of the heat-insulating outer frame 1.

[0028] The width of the isolation frame 13 is smaller than the width of the lifting and drying body 2. The air can circulate through the space between the two sides of the isolation frame 13 and the inner side of the heat-insulating outer frame 1. Hole grooves matching the heat dissipation fans 15 are evenly provided on the isolation frame 13, and the heater 16 is located directly below the isolation frame 13.

[0029] Working principle: During use, first set the control program through the PLC controller 6, then adjust the height of the lifting and drying body 2 according to the thickness of the conventional lamination. Control the lifting of the electric push rod 3 through the PLC controller 6 to drive the lifting bracket 14 to move up and down, thereby driving the lifting and drying body 2 to move up and down. Adjust the height of the lifting and drying body 2 according to the position of the reserved support hole 8. After adjustment, turn the heat insulation plug cover 7 away from the support hole 8 by an external force, and insert the support rod 11 into the inner side of the support hole 8 and at the same time insert it through the hole slot on the support connecting frame 12 into the support hole 8 on the other side of the heat insulation outer frame 1 to strengthen the support for the lifting and drying body 2 and reduce the force on the electric push rod 3. Then pass the laminated item through between the heat insulation outer frame 1 and the support base 4. Then start the heat dissipation fan 15 and the heater 16 through the PLC controller 6. The heater 16 starts high-temperature heating. The heat dissipation fan 15 absorbs the air between the lifting and drying body 2 and the isolation frame 13 and blows it downward. The flow of the air pushes the hot air at the heater 16 to move downward. The hot air reaches the top of the laminated item for heating and drying operations. The hot air blows to the top of the laminated item and moves to both sides. The hot air continuously blows downward from top to bottom and moves and diffuses to both sides. The air between the lifting and drying body 2 and the isolation frame 13 decreases and the air pressure drops. The air on both sides inside the heat insulation outer frame 1 moves upward to between the lifting and drying body 2 and the isolation frame 13, thus forming an air circulation. Moreover, the air flowing back to between the lifting and drying body 2 and the isolation frame 13 is hot air, and when it is blown to the heater 16 by the heat dissipation fan 15 for heating, it absorbs heat and cools down, thereby reducing power consumption. When the PLC controller 6 receives the temperature information transmitted by the temperature sensor 9 and reaches the predetermined temperature range, the PLC controller 6 controls the heating temperature of the heater 16 to decrease to the predetermined value.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
