A dryer is installed on the inner wall of the machine body, a winding unit is installed on the outer wall of the machine body, a cylinder is installed on the top of the frame, and a cleaner is installed on the top of the machine body. This prior art uses the cylinder to drive a cutting blade, which cuts the high-barrier film at the top of the plate, achieving rapid cutting of the high-barrier film.

[0004] The aforementioned prior art has the following shortcomings in actual implementation: the prior art dries the high-barrier membrane by means of a fan and a heater. The fan is arranged at the top of the device and blows hot air from top to bottom for drying. However, the high-barrier membrane is laid on the conveyor shaft, and the part of the high-barrier membrane in contact with the conveyor shaft cannot be effectively dried, resulting in low drying efficiency. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes a drying device for producing high-barrier films, thereby resolving the issues present in the prior art.

[0006] To achieve the above objectives, the present invention provides a drying device for the production of high-barrier films, comprising: a housing;

[0007] A conveying assembly arranged inside the box body is used to convey a high-barrier membrane;

[0008] The first hot air assembly arranged on both sides of the box is used to input hot air into the interior of the box;

[0009] Multiple air ducts extending along the length of the housing are distributed at the bottom of the housing. Each air duct has multiple air outlets and is located below the conveying assembly.

[0010] The outer wall of the housing is provided with a second hot air assembly, which is connected to the air duct and is used to input hot air into the air duct.

[0011] Furthermore, a temperature sensor is arranged inside the enclosure, and a display device is installed on the outer wall of the enclosure, with the temperature sensor electrically connected to the display device.

[0012] Furthermore, an exhaust fan is provided on the top of the housing, the input end of the exhaust fan is connected to the interior of the housing, and the output end of the exhaust fan is connected to an exhaust pipe.

[0013] Furthermore, a connecting shaft is rotatably provided at both ends of the interior of the housing, and a baffle is fixedly provided on the connecting shaft. A second motor is provided at some ends of the housing, and the output end of the second motor is connected to the connecting shaft.

[0014] Furthermore, the first hot air assembly includes a plurality of first protective boxes arranged opposite each other on both sides of the housing, an electric heating plate arranged inside the first protective box, and a first fan installed on the outer wall of the first protective box;

[0015] The first protective box is connected to the interior of the box body, and the first fan is connected to the first protective box.

[0016] Furthermore, the second hot air assembly includes a second protective box fixedly installed on one side of the housing, an electric heating plate disposed inside the second protective box, and a plurality of second fans installed on the outer wall of the second protective box;

[0017] The second fan is connected to the second protection box;

[0019] Furthermore, multiple synchronous pulleys are rotatably arranged on the other side of the housing. The synchronous pulleys are fixedly connected to the other end of the air duct. Two adjacent synchronous pulleys are connected to a synchronous belt. A protective shell is provided on the outer wall of the other side of the housing.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. During the conveying process, the first hot air assembly dries the high-barrier film, while the second hot air assembly is activated to deliver hot air into the air conveyor duct and out through the air outlet on the air conveyor duct. This allows for the drying of the bottom of the high-barrier film, facilitating the drying of the part of the high-barrier film that contacts the conveyor roller and accelerating the drying efficiency.

[0023] Second, when drying the bottom of the high-barrier membrane through the air duct, starting the first motor drives the synchronous pulley to rotate, which in turn drives the air duct to rotate synchronously. The rotated air duct outputs more even hot air, resulting in more uniform drying and facilitating the drying of the high-barrier membrane. A timing belt allows multiple synchronous pulleys to rotate synchronously.

[0031] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of this utility model are now described with reference to the accompanying drawings. However, the scope of protection of this utility model is not limited to the following description.

[0032] Reference Figure 1-5 As shown, a drying apparatus for producing high-barrier films includes: a housing 1; a conveying assembly arranged inside the housing 1 for conveying high-barrier films; and a first hot air assembly arranged on both sides of the housing 1 for inputting hot air into the housing 1.

[0033] The conveying assembly includes multiple conveying rollers 17 rotatably disposed inside the housing 1, and a motor arranged on the outer wall of the housing 1, with the output end of the motor connected to the conveying rollers 17.

[0034] Multiple air ducts 16 extending along the length of the housing 1 are distributed at the bottom of the housing 1. Multiple air outlets 18 are provided on the air ducts 16. The air ducts 16 are located below the conveying assembly. A second hot air assembly is provided on the outer wall of the housing 1. The second hot air assembly is connected to the air ducts 16 and is used to input hot air into the air ducts 16.

[0035] The present invention provides a technical solution in which a high-barrier film is laid on a conveyor roller 17 during use. The conveyor roller 17 is then rotated by a motor to transport the high-barrier film. During transport, a first hot air assembly is used to dry the high-barrier film. At the same time, a second hot air assembly is activated to transport hot air into the air duct 16 and out through the air outlet 18 on the air duct 16. This allows for the drying of the bottom of the high-barrier film, facilitating the drying of the part of the high-barrier film in contact with the conveyor roller 17 and accelerating the drying efficiency.

[0036] Preferably, a plurality of synchronous pulleys 9 are rotatably arranged on the other side of the housing 1. The synchronous pulleys 9 are fixedly connected to the other end of the air duct 16. Two adjacent synchronous pulleys 9 are connected together by a synchronous belt 10. A protective shell 6 is provided on the outer wall of the other side of the housing 1. A first motor 7 is fixedly arranged on the outer wall of the protective shell 6. The output end of the first motor 7 is connected to one of its synchronous pulleys 9.

[0037] Specifically, when drying the bottom of the high-barrier membrane through the air duct 16, starting the first motor 7 drives the synchronous pulley 9 to rotate, which in turn drives the air duct 16 to rotate. After rotation, the hot air output by the air duct 16 is more uniform, resulting in more even drying, thus facilitating the drying of the high-barrier membrane. The synchronous belt 10 allows multiple synchronous pulleys 9 to rotate synchronously.

[0038] Preferably, the first hot air assembly includes a plurality of first protective boxes 4 arranged opposite to each other on both sides of the housing 1, an electric heating plate arranged inside the first protective box 4, and a first fan 5 installed on the outer wall of the first protective box 4. The first protective box 4 is connected to the interior of the housing 1, and the first fan 5 is connected to the first protective box 4.

[0039] The second hot air assembly includes a second protective box 11 fixedly installed on one side of the housing 1, an electric heating plate disposed inside the second protective box 11, and a plurality of second fans 12 installed on the outer wall of the second protective box 11; the second fans 12 are connected to the second protective box 11; and one end of a plurality of air ducts 16 extends into the interior of the second protective box 11.

[0040] Specifically, after activating the heating plate inside the first protection box 4, the first fan 5 is also activated. The first fan 5 blows air into the box 1, and the gas is heated after passing through the heating plate, so the gas input into the box 1 is hot gas. The second motor 12 blows air into the second protection box 11, and after being heated by the heating plate, it enters the air duct 16.

[0041] Preferably, a temperature sensor 15 is arranged inside the housing 1, a display device is provided on the outer wall of the housing 1, the temperature sensor 15 is electrically connected to the display device, an exhaust fan 2 is provided on the top of the housing 1, the input end of the exhaust fan 2 is connected to the inside of the housing 1, and the output end of the exhaust fan 2 is connected to an exhaust pipe 3.

[0042] Specifically, the temperature sensor 15 can sense the temperature inside the chamber 1 and the temperature input is fed back to the display device for staff to view. When the temperature is too high, the first hot air component and the second hot air component are turned off, and the exhaust fan 2 is turned on at the same time to ventilate, which can reduce the temperature inside the chamber 1 and prevent the high-barrier membrane from being damaged by the high temperature.

[0043] Preferably, a connecting shaft 14 is rotatably provided at both ends of the inner side of the housing 1, and a baffle 13 is fixedly provided on the connecting shaft 14. A second motor 8 is provided at some ends of the housing 1, and the output end of the second motor 8 is connected to the connecting shaft 14.

[0044] Specifically, the baffle 13 effectively blocks the gas inside the chamber 1, reducing the outflow of hot gas and saving resources. When ventilation is needed, the second motor 8 is started to drive the connecting shaft 14 to rotate, which in turn drives the baffle 13 to rotate, increasing the opening and facilitating ventilation.

[0045] It should be noted that a controller can be installed inside the housing 1. The controller is electrically connected to the second motor 8, the temperature sensor, and the exhaust fan. The controller automatically controls the opening and closing of the exhaust fan and the second motor 8.

[0046] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
