Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
As shown in FIG. 1, the embodiment of the application provides a flattening device applied to an anti-ribbing and anti-wrinkling BOPP film, which is fixedly arranged between a feeding roller assembly 1 and a corona roller assembly 2 through a frame, and comprises an air flow treatment assembly 3, a bow roller assembly 4 and a press roller assembly 5. The feeding roller assembly 1, the airflow processing assembly 3 and the arched roller assembly 4 are sequentially fixed on the left side (feeding side) of the frame from bottom to top; the corona roller component 2 and the discharging guide roller component 6 are sequentially fixed on the right side (discharging side) of the frame from top to bottom; the compression roller assembly 5 is fixed inside the frame on the left side of the corona roller assembly 2. The film is driven by the discharging guide roller assembly 6 and is contacted with the feeding roller assembly 1, the bow roller assembly 4, the pressing roller assembly 5, the corona roller assembly 2 and the discharging guide roller assembly 6 in sequence. The film between the feed roll assembly 1 and the bow roll assembly 4 has a cambered appearance due to the blowing of the air flow processing assembly 3, and the rest areas are in a tensioned state.
Wherein the content of the first and second substances,
as shown in fig. 2, the gas flow treatment assembly 3 comprises a housing 31, a control line 32 and a gas heater 33. The housing 31 has an air passage therein and a plurality of fan-shaped air flow nozzles 34 on a surface thereof communicating with the air passage. After an external air source is connected to the air heater 33 through a pipeline for heating, the external air source enters the air passage of the shell 31 at a certain flow rate under the regulation of the control pipeline 32 and is sprayed out by the fan-shaped air flow nozzle 34. The ejected air flow acts on the lower surface of the film, so that the film is suspended outside the shell. The surface wrinkles of the heating film are removed under the blowing of the air flow, and the heating film is arched.
The fan jet nozzle is oriented to be inclined toward the arcuate roller assembly so that the arcuate roller assembly can receive the film in the appropriate location in the arcuate region of the film.
The film enters the press roll assembly after being stretched and flattened by the bow roll assembly.
As shown in fig. 3, the pressing roller assembly 5 includes a first pressing roller 51 and a second pressing roller 52. The first pressing roller 51 may adjust its gap with the second pressing roller 52 according to the film thickness. The first and second press rollers 51, 52 are similar in construction, having cavities adjacent the roller faces thereof. The roller shaft is communicated with an external circulating cooling device through a pipeline at the roller shaft, and a circulating cooling medium is guided into the cavity. The external circulation cooling device may share the cooling apparatus used by the corona roller assembly.
When the device works, the film is horizontally fed from the feeding roller assembly and then is upwards guided into the bow-shaped roller assembly. In the material guiding process, the temperature is raised and the wrinkles are removed by the air flow at the air flow processing assembly, and the air flow processing assembly is arched. The arched roller assembly and the arched film area roll clockwise after receiving the film, and stretch the film to the upper right to flatten the film on the roller surface. And the flattened film is then led into the compression roller assembly obliquely below, and after the heat exchange cooling of the roller surfaces of the two compression rollers and the sizing through the gap of the two compression rollers, the film is led into the corona roller assembly obliquely above from the second compression roller of the compression roller assembly for corona treatment. After the corona treatment is finished, the material is horizontally discharged after being guided downwards by the discharging guide roller assembly.
