Cast Film Machine working principle

Under the market demand, the casting machine enters the market. Which brings convenience to people's work. So how does it work?


Add plastic particles to the hopper, plasticize and melt the plastic particles through a single-screw extruder. And then come out of the die of the main machine. .


Small-scale precision casting machine is composed of precision single-screw extruder module and casting machine auxiliary machine module.


Single-screw extruder module consists of main motor, gear reduction case, feed base, thrust package, screw, barrel, transition body, die, heating / cooling system, operation screen, etc. Barrel and screw: The barrel and screw are one of the core working parts of the extrusion unit.


 Made of high-performance materials, the barrel surface is nitrided.


Casting machine auxiliary machine module consists of casting roller, traction roller, traction roller pressing mechanism and rewinding, etc.


1. Casting roller: 1. Each power roller is driven by a servo motor, the roller speed is controlled accurately, and the synchronization performance is good; 2. The height of the casting roller can be adjusted up and down, which can meet the process requirements for casting of different solution strength materials; 3 .Hard chrome plated mirror roller with 304 stainless steel roller core, high surface finish, no rust; 4. Built-in circulating water cooling, precise control of casting roller temperature.


2. Traction roller: The traction roller is composed of upper and lower rollers. The traction upper roller is driven by an independent motor, and the speed is adjustable. The surface of the lower roller is covered with silica gel, and the material is soft. The cylinder can be controlled to drive the lower roller to move up and down.


3. Traction roller pressing mechanism: The traction roller pressing mechanism is composed of a button and an air cylinder, etc.


Press the button to adjust the gap between the upper roller and the lower roller. When pressing the pressing button, the lower roller is pressed upward. When pressing the release button, the lower roller is retracted. After the traction roller is pressed. The surface of the traction roller will be deformed to compress the thin belt between the two rollers, and the thin belt will be moved in the horizontal direction under the action of friction. The speed of the upper roller is adjusted.


4. Take-up roller The take-up roller is driven by an independent torque motor with adjustable speed and built-in air pressure device. The paper tube is sleeved on the roller, and then filled with air to increase the friction between the paper tube and the roller. volume.


The casting machine is actually a simple device and it is easy to operate. I hope that through this article, everyone has a deeper understanding of the casting machine.
