Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of decorative film production equipment, and particularly relates to a decorative film drying device. Background Art
[0002] The drying process is an essential part of the decorative film processing flow. Usually, multiple fans or blowers are used to directly blow air on the surface of the decorative film for drying. However, when dealing with a relatively large-area decorative film, this drying method may not achieve uniform drying of the decorative film, resulting in defects such as wrinkles on the film surface.
[0003] When using a blower for drying, it is easy to introduce dust and other impurities, which adhere to the surface of the decorative film, leading to a decline in product quality. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problems of uneven drying effect and easy introduction of dust in the current decorative film drying device described in the above background art. Here, a new decorative film drying device is proposed. This decorative film drying device can uniformly dry the decorative film and isolate the interference of external dust and other impurities.
[0005] The technical solution adopted to achieve the above purpose is a decorative film drying device, which includes an outer box body, an inner box body, a circulation fan, a plurality of driving rollers, a heat exchanger, and a connecting pipe. The inner box body is arranged inside the outer box body. A first feed port is opened on one side of the outer box body, and a discharge port is opened on the other side of the outer box body. A second feed port is opened on one side of the inner box body, and the other side of the inner box body is open. The first feed port is connected to the second feed port through the connecting pipe. The open side of the inner box body is connected to the inner wall of the outer box body. A plurality of air inlets are opened on the top wall of the inner box body, and a plurality of air outlets are opened on the bottom wall of the inner box body. The circulation fan is arranged on the bottom wall inside the outer box body. The plurality of driving rollers are rotatably connected to the inner box body. The heat exchanger is arranged between the inner box body and the outer box body.
[0006] In the above technical solution, the decorative film is dried by the circulation fan. Compared with directly using a fan to blow air on the surface of the decorative film, the drying effect is more uniform. At the same time, the heat exchanger is used to heat the circulating air to increase the drying rate.
[0007] Furthermore, the decorative film drying device further includes a plurality of filter boxes. An installation groove is provided on the side wall of the first feed port of the outer box body, and the filter boxes are arranged in the installation groove.
[0008] Furthermore, each filter box includes a box body and a handle. The handle is fixedly connected to the side wall of the box body, and a plurality of ventilation openings are provided on the top wall and the bottom wall of the box body.
[0009] In the above technical solution, the filter cartridge is installed in the installation groove in a detachable connection manner, facilitating the replacement of the filter cartridge.
[0010] Furthermore, the filter cartridge is filled with drying filler and / or adsorption filler, and the particle sizes of the drying filler and the adsorption filler are larger than the diameter of the ventilation opening.
[0011] In the above technical solution, the circulating air of the box body is dehumidified by the drying filler to maintain a good drying effect, and dust and other impurities are adsorbed by the adsorption filler to prevent them from being adsorbed on the decorative film and affecting the product quality.
[0012] Furthermore, the filter cartridge is located above the circulating fan.
[0013] In the above technical solution, the filter cartridge is installed above the air outlet of the circulating fan, making the adsorption or dehumidification effect better.
[0014] Furthermore, the plurality of drive rollers are arranged in a wavy distribution.
[0015] In the above technical solution, through the wavy arrangement, the path of the decorative film in the inner box body is longer, the drying time is extended, and the drying effect is enhanced.
[0016] Furthermore, two of the side walls of the inner box body are connected to the corresponding two side walls of the outer box body.
[0017] In the above technical solution, the corresponding front and rear walls of the inner box body and the outer box body are connected, so that the circulating air can only form a circulation loop from the upper, lower and left sides of the inner box body, making the drying efficiency higher.
[0018] Furthermore, the decorative film drying device further includes a humidity sensor, and the humidity sensor is arranged on the inner wall of the inner box body.
[0019] In the above technical solution, the humidity inside the box body is monitored in real time through the humidity sensor. When the humidity exceeds the limit value, the worker can replace the filter cartridge in time to maintain the drying effect.
[0020] Furthermore, the humidity sensor is located on the side wall of the inner box body close to the air inlet.
[0021] In the above technical solution, the humidity sensor is located on the air inlet side to detect the humidity of the circulating air after passing through the filter cartridge, and the detection effect is more accurate.
[0022] Furthermore, the heat exchanger is fixed above the top wall of the inner box body.
[0023] Furthermore, a wind guide cover is provided at the air inlet of the circulating fan, and the peripheral side of the opening of the wind guide cover is attached to the bottom wall of the outer box body and the bottom wall of the inner box body.
[0024] The advantages of the present utility model are as follows:
[0025] 1. The present utility model dries the decorative film through a circulating fan, and monitors and controls the humidity inside the box in real time through a humidity sensor and a drying filter box, so that the drying effect of the decorative film remains good.
[0026] 2. The present utility model forms a closed circulating air duct by connecting the inner box body and the outer box body, preventing impurities such as dust brought from the outside, and further adsorbing and treating the dust through the filter box filled with adsorption filler.

A second feed inlet 9 is provided on the left side of the inner box body, and the right side of the inner box body is open. The first feed inlet is connected to the second feed inlet through the connecting pipe. The right side of the inner box body is connected to the right side wall of the outer box body, and the front and rear walls of the inner box body are connected to the front and rear walls of the outer box body. A plurality of air inlets 10 are evenly arranged on the top wall of the inner box body, and a plurality of air outlets 11 are evenly arranged on the bottom wall of the inner box body.
[0035] The circulating fan is arranged at the lower left corner inside the outer box body. The air inlet of the circulating fan faces upward, and the air outlet of the circulating fan faces right. A wind guide cover 17 is installed at the air outlet of the circulating fan. The cover opening of the wind guide cover is rectangular, and its periphery is attached to the bottom wall of the inner box body and the bottom wall of the outer box body.
[0036] An installation groove is opened above the first feed inlet on the left side wall of the outer box body. The filter box is arranged in the installation groove, and the filter box is detachably connected to the outer box body.
[0037] As Figure 3 shown, the filter box is composed of a box body 14 and a handle 13. The handle is fixedly connected to the side wall of the box body. Uniform ventilation openings 15 are opened on the top wall and the bottom wall of the box body. Drying filler and / or adsorption filler is filled inside the box body, and the particle size of the drying filler and the adsorption filler is larger than the diameter of the ventilation opening.
[0038] In this embodiment, 6 filter boxes are provided. Among them, 3 filter boxes are filled with drying filler, and 3 filter boxes are filled with adsorption filler. The drying filler is silica gel desiccant, and the adsorption filler is activated carbon material.
