[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A film coating and drying device includes a housing 1, with an inlet 2 and an outlet 3 on both sides of the housing 1. A heating chamber 4 is fixedly installed on one side of the housing 1. A gas supply pipe 5 and a gas return pipe 6 are fixedly connected to the top and bottom of the heating chamber 4, respectively. A cylindrical body 7 is provided on both the gas supply pipe 5 and the gas return pipe 6, and a fan blade is rotatably installed inside the cylindrical body 7. A cover 8 is fixedly connected to the top and bottom of the housing 1. The end of the gas supply pipe 5 is fixedly connected to the top cover 8, and the end of the gas return pipe 6 is fixedly connected to the bottom cover 8. The body 8 is fixedly connected. The side of the housing 1 is provided with a driving component 9 for driving two sets of fan blades to rotate simultaneously. The driving component 9 includes a motor 91 fixedly installed on the side of the housing 1, a double transmission wheel 92 fixedly installed on the end of the output shaft of the motor 91, a crossbar 93 rotatably installed on the air supply pipe 5 and the air return pipe 6, a driven wheel 94 fixedly installed on the ends of the two sets of crossbars 93, and a belt 95 sleeved between the double transmission wheel 92 and the two sets of driven wheels 94. The ends of the two sets of crossbars 93 are respectively fixedly installed to the middle of the fan blades.

[0027] In the film coating and drying treatment device, the motor 91 on the side of the box 1 is started, and its output shaft drives the double transmission wheel 92 to rotate. The double transmission wheel 92 drives the two sets of driven wheels 94 to rotate synchronously through the belt 95. The two sets of driven wheels 94 drive the crossbar 93 fixed to them to rotate, and the crossbar 93 in turn drives the fan blades inside the cylinder 7 to rotate.

[0028] The hot air generated by the heating box 4 is delivered to the cover 8 on the top of the box 1 through the air pipe 5 under the action of the top fan blades. The cover 8 evenly disperses the hot air into the box 1 to dry the coated film that enters from the inlet 2 and moves to the outlet 3.

[0029] After heat exchange, the air, under the action of the bottom fan blades, enters the return air pipe 6 through the cover 8 at the bottom of the box 1, and finally flows back to the heating box 4 for reheating, forming a complete hot air cycle and realizing the reuse of heat energy.

[0030] This film coating and drying device can circulate hot air, which can effectively improve the utilization rate of heat energy, reduce heat loss, make the film more evenly heated, shorten the drying time, improve production efficiency, reduce energy consumption costs, and is highly practical.

[0031] Both inlet 2 and outlet 3 are located in the middle of the side of box 1;

[0032] After being coated with adhesive, the film enters the chamber 1 through inlet 2 in the middle of the side of the chamber 1. After the drying process is completed inside the chamber 1, it is sent out through outlet 3 in the middle of the other side of the chamber 1, ensuring that each area of ​​the film can be evenly contacted by the hot air inside the chamber 1, thus improving the overall drying effect.

[0033] The housing 1 is equipped with evenly distributed rotating rollers 10.

[0034] After the coated film enters the box 1 through inlet 2, it is directly laid on the evenly distributed rollers 10 inside the box 1. When the film moves towards outlet 3, the rollers 10 rotate accordingly. The rolling friction of the rollers 10 replaces the sliding friction between the film and the bottom of the box 1, which greatly reduces the resistance encountered by the film when it moves, allowing the film to move more smoothly and stably inside the box 1 and avoiding damage to the adhesive layer on the film surface due to friction.

[0035] A filter section 11 is provided on the return air pipe 6, and an activated carbon filter screen is provided inside the filter section 11;

[0036] During the hot air circulation process, the harmful gases generated by drying the adhesive film inside the chamber 1 enter the bottom cover 8 with the airflow and then flow into the return air pipe 6. When the airflow containing harmful gases passes through the filter section 11 on the return air pipe 6, the activated carbon filter in the filter section 11 will adsorb the harmful gas components in the airflow. The filtered clean airflow continues to flow back to the heating chamber 4 through the return air pipe 6, effectively preventing the direct emission of harmful gases or their re-entry into the chamber 1 with the hot air, thus ensuring a safe working environment.

[0037] A base 12 is provided directly below the box body 1, and evenly distributed support rods 13 are fixedly installed between the base 12 and the box body 1;

[0038] A base 12 is provided directly below the housing 1, and evenly distributed support rods 13 are fixedly installed between the base 12 and the housing 1 to support the entire device.

[0039] Working principle:

[0040] In the film coating and drying treatment device, the motor 91 on the side of the box 1 is started, and its output shaft drives the double transmission wheel 92 to rotate. The double transmission wheel 92 drives the two sets of driven wheels 94 to rotate synchronously through the belt 95. The two sets of driven wheels 94 drive the crossbar 93 fixed to them to rotate, and the crossbar 93 in turn drives the fan blades inside the cylinder 7 to rotate.

[0041] The hot air generated by the heating box 4 is delivered to the cover 8 on the top of the box 1 through the air pipe 5 under the action of the top fan blades. The cover 8 evenly disperses the hot air into the box 1 to dry the coated film that enters from the inlet 2 and moves to the outlet 3.

[0042] After heat exchange, the air, under the action of the bottom fan blades, enters the return air pipe 6 through the cover 8 at the bottom of the box 1, and finally flows back to the heating box 4 for reheating, forming a complete hot air cycle and realizing the reuse of heat energy.

[0043] This film coating and drying device can circulate hot air, which can effectively improve the utilization rate of heat energy, reduce heat loss, make the film more evenly heated, shorten the drying time, improve production efficiency, reduce energy consumption costs, and is highly practical.

[0044] in,

[0045] After the film is coated with adhesive, it enters the box 1 through the inlet 2 in the middle of the side of the box 1. After the drying operation is completed in the box 1, it is sent out through the outlet 3 in the middle of the other side of the box 1, ensuring that each area of ​​the film can be evenly contacted by the hot air in the box 1, thus improving the overall drying effect.

[0046] After the coated film enters the box 1 from the inlet 2, it is directly laid on the evenly distributed rollers 10 inside the box 1. When the film moves towards the outlet 3, the rollers 10 rotate accordingly. The rolling friction of the rollers 10 replaces the sliding friction between the film and the bottom of the box 1, which greatly reduces the resistance encountered by the film when it moves, allowing the film to move more smoothly and stably inside the box 1, and avoiding damage to the adhesive layer on the film surface due to friction.

[0047] During the hot air circulation process, the harmful gas generated by drying the adhesive film inside the chamber 1 enters the bottom cover 8 with the airflow and then flows into the return air pipe 6. When the airflow containing harmful gas passes through the filter section 11 on the return air pipe 6, the activated carbon filter in the filter section 11 will adsorb the harmful gas components in the airflow. The filtered clean airflow continues to flow back to the heating chamber 4 through the return air pipe 6, effectively preventing the direct emission of harmful gas or its re-entry into the chamber 1 with the hot air, thus ensuring a safe working environment.

[0048] A base 12 is provided directly below the housing 1, and evenly distributed support rods 13 are fixedly installed between the base 12 and the housing 1 to support the entire device.
