Plastic roll making machines are specialized industrial equipment used to produce continuous rolls of plastic film or sheet material. These machines are designed to extrude and process a range of thermoplastic polymers, including polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and others, into uniform and consistent rolls of plastic. The key components and operation of a plastic roll making machine are as follows:
1. Extruder: The bag on roll making machine starts with an extruder, which melts and homogenizes the polymer resin. The extruder feeds the molten polymer into the die.
2. Die: The die is a critical component that shapes the molten polymer into a continuous sheet or film of the desired thickness and width.
3. Cooling System: As the plastic sheet or film exits the die, the roll bag machinery passes through a cooling system, typically a series of rollers or a water bath, to solidify the material.
4. Haul-Off and Winding System: The solidified plastic film or sheet is then pulled through the roll bag making machine by a haul-off mechanism and wound onto a roll for storage and further processing.
The bag on roll making machine is mainly used for processing continuous coil bags, which can seal and automatically change the coil under unmanned operation. Adopted no-tension design, making the roll bag machinery in high-speed operation more stable seal, and firm. Effectively saves the staff, and the factory land.
