JN-2 Automatic High-performance Pressure and Vacuum Thermoforming Machine

Description

Feature：

JN-2 full-automatic high-performance forming machine can save 1/3 manpower and power . During the second production, the waste rate even could be zero. JN-2 could replace the single head plastic forming machine which with low efficiency and waste of electricity to produce the products that cannot be produced by ordinary plastic forming machines in the past (uneven water lines, small gap). Now we use the new generation of JN-2 automatic positive and negative pressure integrated machine to produce difficult plastic forming products and improve the quality and efficiency of the products and finally make the products more perfect.

Application：

It is suitable for the forming of PS, PP, PVC, PET, HPS, and other plastic sheets. Highly transparent, round, square, irregular and other products could be processed on this machine. And it could produce various boxes, plates, trays, bowls, covers, industrial packaging, food packaging, cosmetic packaging and other packaging and other plastic products.

Machine production process flow

Supply sheet →sheet feeding → heating → forming and cooling → cutting → stacking → waste sheet edge winding system

Note: there are three station production lines in total. Operation scheme: manual / automatic integration and mutual switching. Manual is convenient for sampling and control parameter setting.

Introduction

Control system

Taiwan Delta human-machine interface, 10.1-inch color touch screen. The professional operating system of JN-2 includes interfaces such as automatic operation, manual operation, function setting, mechanical animation, fault display, equipment documentation, safety guidance, etc. It also has production parameter memory function, making the entire system operate easily and stably.

Unwinding unit

Cylinder lift is used for unwinding material, and the supporting weight could reach 500 kg. The sheet feeding is driven by rubber rollers. Two metal rods are provided for changing sheets rolls. There are two nozzles specially for spraying silicone oil on the sheet surface to removing sheets from mold easily.

Heating unit

The electric furnace with length of 1850mm is made of heat-resistant stainless steel and there are both upper and lower furnace. Totally 180 pcs “JINNAN” 650W heating tile, imported refractory wire, high-frequency porcelain joint and Aoyi 12-way intelligent module integrated temperature control system are used to make as this machine’s upper heating unit. Its maximum power is 100KW and it has one-to-one temperature control function and integrated fault diagnosis function to realize fault detection, locate and report all pending faults, which could significantly improve production efficiency and minimize machine stop time. Besides, data storage could reach 1000 groups and it is easy to do data management. What’s more, there are electric furnace reciprocating function which could heat the PET sheet in a short time and make the PET material easy to form effectively. And the electric furnace’s exiting function is safe and convenient when there is power failure or machine maintenance

Forming unit：

The length of the forming sheet is not limited within 340~650mm, the width of the forming sheet is 380~760mm, and the maximum forming height is 110 mm. The upper and lower forming mold tables adopt 4.5KW Taiwan servo motor motors, which could control the speed in sections and the accuracy is 0.007mm.

Chain drive：

The width of the chain rail is adjusted by the motor. The main body of the chain rail is designed with an aluminum profile hard anodized buckle groove, which has a long service life. The pull-tab chain is made of silicon steel sheet which is driven by 4.5kw servo motor quickly and accurately. Maximum used sheet thickness PP, PS up to 2.0 mm, PVC, APET, ABS up to 1.5 mm

Cooling system：

10HP chiller + independent big water pipeline

Vacuum system：

Vacuum pump, pumping speed is 100m3 per hour. The super-large vacuum pump and vacuum cylinder capacity design could meet the demand for instant and powerful vacuum release, so that the product could be formed faster and with higher quality.
