JN-3 Automatic High-performance Vacuum Thermoforming Machine

Description

Feature：

JN-3 automatic high-performance vacuum thermoforming machine: applying the latest international plastic sheet forming technology, it is an integrated design of machine, electricity and gas, and is controlled by microcomputer and industrial programmable PLC. With square tunnel type imported radiant heater, ordinary copper mold and aluminum mold are suitable for the production. Its technological process: heating, forming, punching, stacking counting, etc. JN-3 could effectively reduce labor, prevent secondary pollution, improve product quality and product qualification rate.

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 → decomposition and 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-3 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 feeding material, and the supporting weight can reach 500 kg. The sheet feeding is driven by rubber rollers. Two material rods are provided for changing sheets. Two nozzles are specially set up in the upper sheet area for spraying silicone oil, which is convenient for removing sheets from mold.

Heating unit

The electric furnace is made of heat-resistant stainless steel and there are upper and dower furnace. Total 96 pcs German brand 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 60KW 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 forming length is 350~900mm, the forming width is 400~750mm, and the maximum forming height is 110 mm. Sheet width is 430~780mm. The upper and lower forming molds adopt 5.5KW Taiwan servo motor motors, which could control the speed in sections and the accuracy is 0.7c.

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. The drive adopts a 5.5kw servo motor. Maximum used sheet thickness PP, PS up to 2.0 mm, PVC, APET, ABS up to 1.5 mm

Cooling system：

5HP chiller, independent pipeline for powerful high-speed water transport of die plate, independent pipeline for orbital cooling

Vacuum system：

Vacuum pump, pumping speed is 200M3/H. The super-large vacuum pump and vacuum cylinder capacity design could meet the demand for instant and powerful vacuum release, so that the product can be formed faster and with higher quality.
