Description

Technical Field

[0001] This utility model relates to the field of composite film drying technology, specifically a drying device for the production of fiber-drawn composite films. Background Technology

[0002] Wire-drawn composite film is a thin film material with special structure and properties, and it has wide applications in many fields such as packaging, electronics, and medical.

[0003] Chinese patent discloses a drying device for composite film production, publication number CN219347177U, which includes a drying box. The drying box has symmetrically arranged support columns at its bottom end, and symmetrically arranged openings on both sides. Rollers are installed at the top and bottom of the inner walls of the openings. Symmetrically arranged support seats are located at the bottom inner end of the drying box, and support rollers are installed at the top of each support seat. A roller pressing group is located above the support rollers at the top inner end of the drying box, and drying groups are located at both the top and bottom inner ends of the drying box. This design facilitates roller pressing during the drying process of the composite film, effectively pressing down wrinkles on the composite film, improving the flatness of the composite film, and thus improving the quality of the composite film.

[0004] However, the device still has the following drawbacks: It uses a hot air blower to direct hot air to the outer surface of the composite film for drying, but the hot air is not filtered during recirculation, affecting the subsequent drying of the composite film. Therefore, we propose a drying device for the production of fiber-drawn composite films to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for the production of fiber-drawn composite films, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drying device for producing filament composite film, comprising a drying box, wherein a drying device is provided on the drying box, and the drying device includes a drying section;

[0007] The drying section includes a hot air blower and a processing box. The bottom surface of the hot air blower is fixedly connected to the top surface of the drying box, and a return pipe is fixedly and continuously connected to the back of the processing box.

[0008] A filter section is provided in front of the drying chamber;

[0009] The filtration section includes an isolation tube and an air guide tube. An end cap is threaded on the outer surface of the top end of the isolation tube, and the threaded outer surface of the bottom end of the isolation tube penetrates the top surface of the treatment box and extends into the interior of the treatment box. A threaded sleeve is fixedly fitted on the outer surface of the air guide tube.

[0010] A further improvement is that the drying section also includes a guide roller and a baffle plate. The bottom surface of the hot air blower outlet pipe is fixedly connected to the top surface of the drying box, the back surface of the return pipe is fixedly connected to the front surface of the drying box, and the bottom surface of the hot air blower inlet pipe is fixedly connected to the top surface of the processing box. By setting up the hot air blower, the return pipe, and the processing box, after the hot air blower is started, the hot air is circulated to dry the filament composite film, reducing resource waste.

[0011] A further improvement is that the outer surface of the guide roller is rotatably connected to the inner wall of the drying chamber through a bearing seat, and the outer surface of the baffle plate is fixedly connected to the inner wall of the drying chamber. By setting the guide roller, the drying time of the filament composite film is extended, and by setting the baffle plate, the airflow is dispersed.

[0012] A further improvement is that the filtration unit also includes a mounting plate, a partition, a first sealing ring, a filter screen, a limiting frame, a spring, a sealing plate, a sealing gasket, a second sealing ring, and a mounting ring. The outer surface of the air guide duct has a mounting hole, and the outer surface of the filter screen is fixedly connected to the inner wall of the mounting hole. The interior of the air guide duct is used to place activated carbon particles and dehumidifying particles. By setting up the air guide duct and the filter screen, activated carbon particles and dehumidifying particles are placed to treat the returned hot air.

[0013] A further improvement is that the mounting plate is threaded onto the outer surface of the threaded sleeve, the outer surface of the mounting plate is fixedly connected to the inner wall of the treatment box, the mounting ring is fixedly fitted onto the outer surface of the threaded sleeve, the top surface of the second sealing ring is fixedly connected to the bottom surface of the mounting ring, and the bottom surface of the second sealing ring is pressed against the top surface of the mounting plate. By setting up the mounting plate, the threaded sleeve, the mounting ring, and the second sealing ring, it is convenient to install and disassemble the air duct.

[0014] A further improvement is that the bottom surface of the limiting frame is fixedly connected to the inner wall of the processing box, the top surface of the limiting frame is fixedly connected to the bottom surface of the mounting plate, the outer surface of the sealing plate is slidably connected to the inner wall of the limiting frame, the bottom surface of the sealing gasket is fixedly connected to the top surface of the sealing plate, the bottom end of the spring is fixedly connected to the inner wall of the processing box, and the top end of the spring is fixedly connected to the bottom surface of the sealing plate. By setting the spring, sealing plate, and sealing gasket, when the air duct is removed, the spring force is used to seal the holes on the mounting plate.

[0015] A further improvement is that the outer surface of the partition is fixedly connected to the inner wall of the processing box, and a through hole is opened on the outer surface of the partition. The diameter of the through hole is larger than the diameter of the outer surface of the mounting ring and smaller than the diameter of the inner wall of the isolation tube. The top surface of the first sealing ring is fixedly connected to the bottom surface of the isolation tube. By setting the partition, the isolation tube and the first sealing ring, rotating the isolation tube causes the bottom surface of the first sealing ring to press against the top surface of the partition, so that hot air no longer flows inside the corresponding air guide tube. At this time, the end cap can be removed and the air guide tube can be removed upwards. The activated carbon particles and dehumidifying particles can be replaced without stopping the hot air blower, thereby improving the drying efficiency of the filament composite film.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This drying device for producing composite film consists of an installation plate, air duct, partition, end cap, isolation pipe, first sealing ring, filter screen, threaded sleeve, limit frame, spring, sealing plate, sealing gasket, second sealing ring, and installation ring. Activated carbon particles and dehumidifying particles inside the air duct dehumidify and remove impurities from the returning hot air, facilitating subsequent reheating. To replace the activated carbon particles and dehumidifying particles inside the air duct, the isolation pipe is rotated, causing the first sealing ring to press downwards against the partition, allowing the air duct to be removed upwards. The spring force then seals the through-holes on the installation plate, enabling the replacement of activated carbon particles and dehumidifying particles without stopping the hot air blower, thus improving the drying efficiency of the composite film.

[0018] By setting up a hot air blower, a return pipe, and a processing box, the hot air blower is started to dry the drawn composite film with hot air. The return pipe facilitates the recycling of the hot air.

[0019] By setting up guide rollers and baffles, the drying time of the fiber composite film is extended by using guide rollers, and the airflow is made more dispersed by using baffles. Attached Figure Description

[0032] A filter section 22 is installed at the front of the drying oven 1;

[0033] The filter section 22 includes an isolation pipe 225 and an air guide pipe 222. The outer surface of the top end of the isolation pipe 225 is threaded with an end cap 224. The outer surface of the bottom end of the isolation pipe 225 is threaded through the top surface of the treatment box 215 and extends into the interior of the treatment box 215. The outer surface of the air guide pipe 222 is fixedly fitted with a threaded sleeve 228. The filter section 22 also includes a mounting plate 221, a partition plate 223, a first sealing ring 226, a filter screen 227, a limit frame 229, a spring 220, a sealing plate 201, a sealing gasket 202, a second sealing ring 203, and a mounting ring 204.

[0034] Mounting plate 221 is threaded onto the outer surface of threaded sleeve 228. The outer surface of mounting plate 221 is fixedly connected to the inner wall of treatment box 215.

The activated carbon particles and dehumidifying particles inside the air duct 222 are used to dehumidify and remove impurities from the returning hot air, facilitating subsequent reheating. When replacing the activated carbon particles and dehumidifying particles inside the air duct 222, rotate the isolation tube 225 to press the first sealing ring 226 downward against the partition plate 223, and then remove the air duct 222 upward.

Then, the hot air passes through the air guide pipe 222 and is purified by activated carbon particles and dehumidifying particles. The hot air then enters the hot air blower 211 for reheating. When replacing the activated carbon particles and dehumidifying particles, the isolation pipe 225 is rotated to press the bottom surface of the first sealing ring 226 against the partition plate 22. 3. The top surface prevents hot air from passing through the inside of the air duct 22. At this time, the end cover 224 can be opened to remove the air duct 222 upwards. During the upward movement of the air duct 222, the spring 220 extends, causing the sealing plate 201 and the sealing gasket 202 to move upwards. The top surface of the sealing gasket 202 presses against the bottom surface of the mounting plate 221, sealing the holes on the mounting plate 221. When replacing the activated carbon particles and dehumidifying particles inside the air duct 222, the hot air blower 211 continues to operate and can still dry the filament composite film.
