1. INTRODUCTION

You have bought a machine with outstanding features and performance and we thank you very much for your confidence in choosing it. The NEXGEN-2030 system is a reliable, low priced and handy machine. The technological concept underlying its design, as well as the components and materials used in the manufacturing and testing process are the best assurance of proper operation and long-lasting liability.

2. PERFORMANCES OF THE PACKAGING MACHINE

Thanks to its particular operating circuit, it can be used either as sealing and shrinking machine or as a sealing machine (sealing only). In this case it is possible to pack the object in a soft bag without shrink-wrapping. The film can be punched or not when running through the micro punch of machine itself. The film thickness in the range of 15-50 micron can be used.

NEXGEN-2030

Where the wire with green-yellow color is the earthling wire, the wire with labeling “L” is the live wire; the wire with labeling “N” is the neutral wire.

Make sure all wires are connected properly, in case of doubts about the main voltage contact

the local public supplies company. ATTENTION: Earthing of the machine is obligatory.

5. PRINCIPELS OF OPERATION

SEALING

Sealing and shrinking are done on impulse, set through an automatic control of sealing. The heat of the sealing blade melts film and then it is pressed between sealing blade and sealing tape.

SHRINKING

Film shrinking is obtained contemporaneously to sealing and is produced by the forced circulation of hot air around the package.

Air heating is obtained by making the air pass through a group or thermostat heater.( heating

6. MACHINE ADJUSTMENT AND OPERATION

ADJUSTMENT

①The NEXGEN-2030 can be used as a simple sealing machine or as a machine for sealing and shrinking at the same time.

②Turn the Main Switch (1) into pos.1 to carry out cutting and sealing only. ③Turn the Main Switch (1) into pos.2 to carry out sealing and shrinking in one operation. While in pos.2, before operating machine, wait till the adjusted temperature is reached (7-10 min) which is signaled through the switching off of the Temperature Controller (2).

④Adjust the Temperature Controller (2) into 150℃ which corresponds to on average shrinking temperature, if shrinking is unsatisfactory or the time to obtain it is too long, increase the adjusted value also according to the kind of film used.

⑤Adjust the Sealing Timer (3) into 1 second (for PVC ) corresponding to a medium sealing time. It may be necessary to increase or decrease the set value depend on the type and thickness of the film used. Attention: Increase the sealing time gradually, sealing blade overheat will shorten the life of the blade and blade holder; adjust the interval of the sealing temperature into 2-5mm

(according to the packing material).

⑥Adjust the Shrinking Timer (4) into 4 seconds, then increase or decrease the adjusted value according to the result obtained.

(1) Main Switch

(6) For Model 5540A, there is a Conveyor Timer for standard model to setup the transport time.

INSERTING ROLL OF FILM

Insert the roll of film on the Roller (6) and block it through the Centering cones (7). See Fig6. Run through the Micro punch (8). Run the film lower layer under the Packaging Plate (9). Run the film upper layer over the Packaging Plate (9) and Separator Rod (10). See Fig.6: (6).Roller (7).Centering Cone (8).Micro punch (9).Packing Plate (10).Separator Roll (11).Film Holder

INSTALLATION OF THE SCREEN PLATE

For a proper packing result, the screen plate (12) must be adjusted such that the film sealing is made at the half of the packaging height. See

And the Film Holder (11) and the Packing Plate (9) must be adjusted according to the width of the product to be packed , leaving a space of about 2 cm between the product and the sealing edge.

INTRODUCE THE OBJECT OT BE WRAPPED

After carried out the first seal, the film is now ready to carry out wrapping. As Fig.8 shown, introduce the product Into the bag using the right hand ( see Picture ) and make it slide to the left until it is laid on the screen leaving a little space of about 1-2 cm to allow the passage of air for shrink-wrapping.

OPERATION

By pushing the cover handle with a Pressure of 10-15 kg, the cover Rests on the sealing blade; by Pinching the film, it is automatically sealed on the open sides (right and front). In case you have selected the function SEALING + SHRINK WRAPPING you will see the film shrink onto the product. Slightly decrease the pressure on the cover handle to allow film detaches from the sealing area on the inside. With the right hand detach the film the sealing blade to towards the outside (see Fig. 9)
