SY-PC-A

Diagonal Mono-Layer Plastic Sheet Extrusion Machine

This series is designed to produce mono-layer PP/PS/PE/HIPS plastic sheet, which is used for making disposable water drinking cups, ice-cream cups, yoghurt cups, lids, trays,plates and etc.

Major Construction Features

The sheet extrusion unit is a combination of extruderthree roll calenders,haul-off unit,winderlincluding waste sheet winder and electric control cabinet.
The main parts, such as screw, barrel, screen exchanger, T-die adopt superior alloy steel(38 CrMoAlA) with high hardness strong corrosions resistance and long operating life after nitrogen treatment.
The screw adopts big L/D ratio,equal plasticization and high plasticizing capability.
Non-stop fast screen changer with double-sieve, controlled by hydraulic device, the operation is convenient and improve the production efficiency.
The calendar.haul off unit and winder adopt integration design,fine appearance,convenient and improve the production eficiency.
The machine frame adopt square steel, to make sure the machine works stably in high speed. The motor is connected with gear box directly, improve production efficiency and lower energy consumption.
Note: Special specification and configuration of products can be designed according to customer' s demand.

Product Features

The machine uses a high-power three-phase motor with a 6-stage reducer, which has sufficient power. The reduction box is equipped with an independent water-cooling pipeline to prolong the service life of the reduction box.

The feeding barrel adopts a transparent slotted design so that you can see the remaining material in the barrel and feed the material in time. The screw feed trough adopts a water-cooled design to prevent the blockage of the feed trough caused by melt backflow.

The screw is heated by 6-stage cast aluminum heating tile, using wear-resistant material 58Cr13, and the hardness reaches HV950.

The screen changer adopts double stations hydraulic pressure to ensure the screen changes without stopping and uses 38CrMoAIA high-quality material to prolong the service life.

Using high-precision T-die, which is made of high-quality alloy steel, the inner flow channel is chrome-plated. It has high hardness and strong corrosion resistance capacity.

The calendering three-roller adopts 0.08mm chrome-plated layer, and the hardness can reach HRC58-62. The gap between the main calendering rolls is manually adjusted and equipped with a dial indicator to measure the distance accurately. The accuracy can reach ±0.01mm. The design of the safety rope can stop the machine immediately in case of an accident, improving safety effectively.

The three-roller drive adopts a variable frequency motor synchronous with a chain drive. It can opt for independent motor driving, and adjust the speed of a single roller independently.

Double-station non-stop rewinding device is driven by the torque motor. It has 6-speed adjustable torque, equipping a quick-release rewinding device, which can save your time and effort.
