Abstract

The utility model relates to a flattening assisting device with traction and rolling functions. The device comprises a pair of flattening rollers (1) arranged in parallel left and right. The flattening rollers (1) comprise an upper roller (1.1) and a lower roller (1.2) which are installed on the same supporting frame (1.3), a narrow slit where only one film (3) can pass is formed between the upper roller (1.1) and the lower roller (1.2), and the included angle between the rotating plane of the upper roller (1.1) and the lower roller (1.2) and the operating direction of the film (3) is alpha which is larger than 30 degrees but smaller than 45 degrees. The flattening assisting device with the traction and rolling functions can flatten the film and facilitates improvement of rolling flatness.

Description

Pulling and winding auxiliary flattening device

technical field

The utility model relates to an auxiliary flattening device for pulling and rolling, which is used for flattening a film when the film is rolled.

Background technique

At present, in the process of film winding, there is a lack of corresponding film flattening device. Therefore, during the winding process, the two sides of the film are easy to wrinkle due to not being flattened. When the film is wound on the roll, the film roll The flatness of the film is greatly affected, which leads to a great impact on the film quality and yield.

Contents of the invention

The purpose of the utility model is to overcome the above disadvantages and provide a traction and winding auxiliary flattening device which can flatten the film and help to improve the flatness of the winding.

The purpose of the utility model is achieved as follows: a traction and winding auxiliary flattening device, the device includes a pair of flattening rollers arranged symmetrically on the left and right, and the flattening rollers include an upper roller mounted on the same support frame. A roller and a lower roller, a slit that only allows the film to pass is formed between the upper roller and the lower roller.

In the utility model of the traction and winding auxiliary flattening device, the included angle between the rotation plane of the upper roller and the lower roller and the running direction of the film is α, and α∈(30°, 45°).

Compared with the prior art, the beneficial effects of the utility model are:

The utility model provides a lateral force to the film through the flattening roller, so that the film can be flattened to the left and right sides during operation; the film can be completely flattened when it reaches the winding machine, thereby improving the flatness of winding.

Detailed ways

Referring to Figures 1 to 3, the utility model relates to a traction and winding auxiliary flattening device, the device includes a pair of flattening rollers 1 arranged symmetrically on the left and right, and the flattening rollers 1 include The upper roller 1.1 and the lower roller 1.2 on 1.3, a slit that only allows the film 3 to pass is formed between the upper roller 1.1 and the lower roller 1.2. When in use, the support frame 1.3 is fixed on a fixed frame 2 (wall Or other corresponding fixed objects are available), and the angle between the rotation plane of the upper roller 1.1 and the lower roller 1.2 and the running direction of the film 3 is α, and α∈(30°, 45°); when the film 3 moves forward , the traction force produced by the upper roller 1.1 and the lower roller 1.2 of the flattening roller 1 on the film 3 is f, and the traction force f can be decomposed into a force f1 in the same direction as the movement direction of the film 3, and a force f2 perpendicular to the movement direction of the film 3 , the f2 will make the film 3 move to both sides, so as to achieve the effect of flattening.
