Although this technology can improve the localized collapse of the membrane surface with a collapse width limit ≤ 40mm, it cannot be reshaped for the collapse defects of the membrane surface with a collapse width greater than 40mm, and the imprints caused by wrinkles and ribs on the membrane surface cannot be corrected by this technology. Elimin...

Embodiment 1
[0024] See figure 1 As shown, a device for film surface shaping provided in this embodiment includes a flattening heating roller 1 and a flattening cooling roller 2, and the flattening heating roller 1 is arranged on the side of the flattening cooling roller 2 The front end, and between the flattened heating roll 1 and the flattened cooling roll 2, a press roll A3 for breaking the tension is provided, and the rear end of the flattened cooling roll 2 is also provided with a press roll B4 for breaking the tension.
[0025] The film 5 is first heated and flattened by the flattening heating roller 1, and then the tension is cut by the pressure roller A3, and then cooled and shaped by the flattening cooling roller 2, and then wound up after the tension is cut by the pressure roller B4, that is, shaping After the membrane surface is flat film.
[0026] The temperature range for heating and flattening is preferably 30 to 85°C, and the temperature range for cooling and shaping is pre...
Embodiment 2
[0028] See figure 2 As shown, the difference between the device for film surface shaping provided in this embodiment and embodiment 1 is that the device for film surface shaping includes two flattening heating rollers 1 and two flattening cooling rollers 2 , and the direction of rotation of the two flattening heating rollers 1 is opposite, and the rotation direction of the two flattening cooling rollers 2 is opposite; the film 5 is passed through two flattening heating rollers 1, pressure roller A3, two flattening cooling rollers 2 and The pressure roller B 4 can make the front and back of the film can be heated, flattened and cooled to shape, not only the shaping effect is better, but also the shaping efficiency is higher.
[0029] In addition, the flattening heating roll in the present invention refers to a flattening roll with a heating function, which can be obtained by using the heating system of the heating roll and the roll surface shape of the flattening roll; the fla...

Abstract
The invention discloses a method and device for film surface shaping. The method comprises the steps that a thin film is firstly heated and flattened, then the heated and flattened thin film is subjected to tension cutoff, cooling and sizing are carried out, and the thin film obtained after cooling and sizing is subjected to tension cutoff again. The device comprises at least one flattening and heating roller and at least one flattening and cooling roller. A press roller A used for cutting off tension is arranged between the flattening and heating rollers and the flattening and cooling rollers, and a press roller B used for cutting off tension is also arranged at the rear ends of the flattening and cooling rollers. According to the method and device, film surface defects with the collapse width being smaller than or equal to 200 mm can be effectively flattened, traces generated by film surface wrinkling and veining can be completely eliminated, and the flatness of the thin film can be obviously improved; the online operating speed of the thin film can reach up to 100 m/min or above, and the shaping efficiency is obviously improved; and in addition, a roller type structure is adopted, the structure is simple, operation is easy, and the shaping requirements of thin films of different breadths are easy to meet.
Description
technical field [0001] The invention relates to a method and device for film surface shaping, belonging to the technical field of film shaping. Background technique [0002] Thin film is a thin and soft metal or organic layer with a thickness ranging from a single atom to a few millimeters. It can be divided into optical films, composite films, superconducting films, polyester films, nylon films, plastic films, etc. Widely used in electronic appliances, machinery, printing, medical and health, construction, automobile, packaging, agricultural, military and other fields. Due to the complex production process of the film, which involves multiple processes such as coating, extraction, slitting, and coiling, it needs to go through multiple rolling and winding operations. Its own tension and pressure make the film surface tend to be flat, or use fixed and formed flattening rollers, the flattening effect can only be partially achieved, but most of the time the ideal effect cannot...
