Abstract
Description
Technical Field
[0001] The utility model relates to the field of production and processing of cling film, in particular to a cling film drying device. Background Art
[0002] During the production process of cling film, it needs to be dried to facilitate the winding and packaging of the cling film. However, since the cling film is relatively soft, a support roller is usually required to support the cling film during drying. When the support roller contacts the cling film, the liquid on the cling film will remain on the upper surface of the support roller, resulting in the contact surface between the cling film and the support roller being unable to dry completely. Summary of the invention
[0003] The utility model mainly solves the above-mentioned problem and provides a cling film drying device which can keep the surface of the supporting roller dry and thus ensure that the contact surface between the cling film and the supporting roller can be completely dried.
[0004] The technical solution adopted by the utility model to solve its technical problems is a fresh-keeping film drying device, comprising a drying chamber, an exhaust fan, a feed roller, a discharge roller, a warm air unit and a plurality of support rollers, wherein the feed roller and the discharge roller are respectively arranged on the left and right sides of the drying chamber, the support rollers are distributed between the feed roller and the discharge roller, the support rollers comprise a pair of roller frames, two turntables, a motor and at least two roller bodies, the turntables are rotatably arranged on the roller frames, the two turntables are arranged opposite to each other, the roller bodies are rotatably arranged on the two turntables and are evenly distributed on the turntables, the motor is used to drive the turntable to rotate, and the warm air unit is arranged on the top of the drying chamber.
[0005] As a preferred embodiment of the above scheme, the heating unit includes an air inlet, a drying layer, a filtering layer, a heating tube, a fan and an air outlet from top to bottom.
[0006] As a preferred embodiment of the above scheme, a plurality of air outlets are provided, and the air outlets correspond to the support rollers one by one. A fan is provided at each air outlet, and the fan is turned off when the motor is running.
[0007] As a preferred embodiment of the above scheme, the exhaust fans are arranged on the top and sides of the drying chamber.
[0008] The utility model has the advantages that the supporting roller is provided with a plurality of roller bodies, each roller body can alternately support the cling film, so that the roller body in contact with the cling film can be in a dry state, thereby ensuring that the contact surface between the cling film and the supporting roller can be completely dried.

[0012] The technical solution of the utility model is further described below through embodiments and in conjunction with the accompanying drawings.
[0013] Example:
[0014] This embodiment provides a cling film drying device, such as Figure 1 As shown, it includes a drying chamber 1, an exhaust fan 2, a feed roller 4, a discharge roller 5, a warm air unit 3 and a plurality of support rollers 6. The feed roller 5 and the discharge roller 6 are respectively arranged on the left and right sides of the drying chamber, and the support rollers 3 are distributed between the feed roller 5 and the discharge roller 6. The cling film 7 enters the drying chamber from the left side and passes through the feed roller 4, the plurality of support rollers 6 and the discharge roller 5 in sequence, and then is led out from the right side of the drying chamber. A warm air unit is arranged above the support rollers, and the warm air mechanism outputs warm air to dry the cling film. The exhaust fan is arranged on the top and side of the drying chamber, and is used to extract water vapor in the drying chamber to maintain a low humidity in the drying chamber to facilitate the drying of the cling film.
[0015] In this embodiment, the three groups of heaters include an air inlet, a drying layer 31, a filter layer 32, a heating pipe, a fan and an air outlet 33 from top to bottom. The number of air outlets is equal to the number of support rollers and corresponds one to one. Fans are arranged in each air outlet, and each fan is independent of each other. The drying layer 31 and the filter layer 32 are used to ensure that the air blown out by the heater group remains dry and dust-free, and prevent the cling film from being contaminated with dust.
[0016] like Figure 2 As shown, the support roller includes a pair of roller frames 61, two turntables 62, a motor 64 and at least two roller bodies 63. The turntable 62 is rotatably arranged on the roller frame 61. The two turntables 62 are arranged opposite to each other. The roller bodies 63 are rotatably arranged on the two turntables 62 and are evenly distributed on the turntables 62. The motor 64 is used to drive the turntable to rotate. The warm air blower is arranged on the top of the drying chamber. When the cling film is dried, the motor drives the turntable to rotate regularly so that the two roller bodies can alternately contact the cling film, giving the roller body drying time to avoid the cling film from being completely dried due to the long-term moisture of the roller body. In addition, the air outlet is located directly above the support roller. When the motor drives the turntable to rotate, the fan at the corresponding air outlet is turned off to prevent the cling film from being deformed by the warm air without support.
[0017] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
