Main cold roller mechanism of biaxially oriented film production line

Abstract

The invention provides a main cold roller mechanism of a biaxially oriented film production line, relates to the technical field of film production, and solves the problems that a limiting structure cannot realize auxiliary current limiting of wind power and cannot play an auxiliary role when other structures are mounted. The main cold roller mechanism of the biaxially oriented film production line comprises a frame body, a cooling part is installed on the frame body, and a second cooling part is further installed on the frame body. Due to the fact that an auxiliary base is of a concave structure, the auxiliary base is located above a blade A, and the auxiliary base forms a blocking structure for the blade A to generate wind power, most of the wind power generated by the blade A is blown to a box body under blocking of the auxiliary base, and then the auxiliary cooling effect of liquid in the box body is achieved. A plate body is of a rectangular plate-shaped structure, and the top end face of the plate body makes contact with the bottom end face of the auxiliary base, so that vertical limiting of the plate body can be achieved through the auxiliary base when the plate body is installed, and then the installation efficiency of the plate body is improved.

Description

technical field [0001] The invention belongs to the technical field of film production, and more specifically relates to a main cooling roll mechanism of a biaxially stretched film production line. Background technique [0002] During the production process of plastic film, the plastic in the molten state is extruded from the lip of the flat die and poured onto the surface of the main cooling roll, and is cooled rapidly to form a film. [0003] For example, the application number: CN202010848933.1, the invention discloses a main cooling roller device of a biaxially stretched film production line, which includes a receiving seat, a roller body rotatably arranged on the receiving seat, and a drive for driving the roller body to rotate. Mechanism; it is characterized in that it also includes a spray mechanism arranged in the inner cavity of the roller, a water supply mechanism for sending cold water to the spray mechanism, and a drainage mechanism for draining the accumulated w...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides the main cooling roll mechanism of the biaxially stretched film production line to solve the existing problem that although the existing device can cool the roll body when the air flow passes through the roll body, the roll body cannot be disassembled. As a result, the difficulty of maintenance is increased; moreover, the existing device cannot achieve auxiliary cooling through structural improvement; finally, the limiting structure of the existing device cannot realize the auxiliary flow restriction of the wind force, and cannot be used in other structures Problems that play an auxiliary role during installation
