Working process of film roller cooling line

The film roller cooling line is an automated equipment used to handle hot film in the rubber product production process. Its working process involves multiple consecutive steps to ensure that the film is properly cooled, dried and post-processed. Here is a detailed description of the working process of this device:

1. Film receiving and conveying: After the film is pressed out from the tablet press, it is received by the pick-up and conveying device of the cooling line and smoothly transported to subsequent processing. This device usually includes adjustable belts and fixed rollers to ensure the stability of the film during transportation.

2. Imprinting and film joint: During the transportation process, the film will be imprinted by a device to identify the film information, such as letters and numbers. In addition, the device can cut the film into strips of the required width to accommodate subsequent processes.

3. Release agent coating and preliminary cooling: The film then enters a cooling stirring device, where the film is soaked and coated with release agent for preliminary cooling. The device is equipped with a temperature control function to ensure the appropriate temperature of the release agent and prevent the film from sticking.

4. Film lifting: Through the clamping and lifting device, the film is lifted to a certain height to prepare for the subsequent cooling and conveying process. This process uses heat-resistant rubber belts to ensure stable transportation of the film under high temperature conditions.

5. Cooling conveying: In the glue-hanging cooling conveying device, the film is further cooled and conveyed through a suspended conveying system in a closed cooling box to achieve uniform cooling.

6. Film placement and stacking: The cooled film is sent to the placement device through the downward conveyor device, and the stacking and swing amplitude are automatically adjusted to prepare for the subsequent cutting and stacking processes.

7. Film cutting, stacking and weighing: In the stacking lifting device, the films are pressed symmetrically and stacked neatly. The device is also equipped with a weighing system that automatically cuts the film based on its weight and prints production information.

8. Pneumatic and electrical control systems: Pneumatic components and electrical controls are important components of the film cooling line. The pneumatic system is responsible for executing various mechanical actions, while electrical control is realized through a PLC system, such as the Siemens S7-300 series, ensuring automated control of the entire cooling line.

9. Ventilation and cooling system: In order to ensure the cooling effect of the film, the ventilation and cooling system adopts centralized ducted air supply. By controlling the air inlet volume of each part, it ensures the temperature control of the film during the continuous production process.

Through the above-mentioned continuous automated process, the film roller cooling line realizes a fully automated production process from film receiving, cooling, drying to final cutting, folding and stacking, significantly improving the automation level and production efficiency of the rubber product production line.
