Automatic Heat Transfer Screen Printing Line (with wicket dryer)

Automatic heat transfer label printing line(wicket dryer)

1.GST720 automatic stop cylinder screen printing machine

Brief Introduction

GST Series Automatic Stop-cylinder Screen Printing Machine are upgrade models from Rotary Cylinder Printing Machine recent years. This kind of machine has adopted classical "Stop-cylinder" printing movement instead of the original "reciprocating movement". Therefore, it not only ensures the paper accurate position before scratch- print, but also reduce the producing waster rate. Besides, there is little impact with such high speeds and revolving, which also improves the register precision.

Main Features

1. Driven by variable frequency brake motor, the whole machine is operated under the centralized control of Mitsubishi PLC. The WEINVIEW-touch screen operation interface displays all functional data, making printing operation more simple and convenient;

2. Adapt the Omron automatic optical fiber positioning detection, in case of, paperless and paper stuck, automatically rises and stops to reduce printing paper waste;

3. Full alarm system to prompt operators to carry out exact troubleshooting, making maintenance easy and fast;

4. The main electrical components are imported from international brand, which greatly improves the stability of the electrical system and reduces the maintenance and overhaul

5. The printing cylinder is made of stainless steel 316L, which is precise and durable. Flexible design of the elastic range of the paper teeth, convenient for the printing of different thickness of paper at any time;

6. The exit paper board can be turned 90 degrees, which is easy to clean screen. Screen can be adjusted up and down, front and back, right and left position

7. Centralized lubrication control system: main drive parts are lubricated automatically, which can effectively extend the service precision and machine life. Most of the bearings are used from NTN and NSK brand

Detail

1. Front pick up feeder

Front pickup feeder, specially designed for films

More suitable for the film substrate delivery, smooth and stable.

2. Feeding table

Imported stain steel delivery board, reduce static and friction. Rubber and the nylon wheel are suitable for the thin and thick paper adjustment.

It is equipped with the sensors on the table to detect the miss feeding or jam of the sheets and stop the machine automatically

3. Front lay and side lay registration system with the sensor

The side pull lay is easy to adjust the thin paper and thick paper

The side lay and front lay sensors detect the sheets position automatically to make sure the high registration of every paper, greatly reduce the wasted printing

4. The stainless steel printing cylinder

The printing cylinder is made of stainless steel material, which is precise and durable.The paper teeth on the cylinder is designed to be flexible, the vacuum and blow air is on the cylinder holes, which is convenient to adjust at any time when printing on different thicknesses and thin papers

5. The frame pull out system

The screen frame can be lifted up and pulled out of the gear, easy to clean the mesh

6. Sheet delivery table

Double vacuum conveyor belt, controlled by the independent frequency. Suitable for different sheet size, avoid the damage to sheets and prevent the paper stuck,

The paper delivery table that can be flipped 90 degrees, convenient for screen cleaning

8. Centralized lubrication control system

Automatic lubrication of main transmission components, effectively prolonging the machine accuracy and machine life

9. Friendly interface and control panel

The operating system is equipped with a 7-inch touch screen, and the redesigned interface makes it more convenient and faster, and the operation is more intuitive.

GWD720 Wicket Dryer
1.GWD720 series wicket dryer is widely used for drying all kinds of printing solvent ink and              paint such as ceramic decal , credit cards and other package printing etc

2.The machine is consisted of heating parts and cooling parts; Heating parts are full close tunnel construct, and cooling parts are open construct without side boards;

3.There are electric heating lamps fixed on the top of heating parts. Through the fans and lead bar fixed in two of the wind boxes, hot air can circulate and the temperature can keep steadily;

4.The machine has digital temperature controller. There are one layer installing on the side board for insulation using;

5.There are two sets of exhausting devices which are fixed separately on the beginning and the end of the heating parts;

6.There are fans fixed on the top of cooling parts, which are used to blow dry the paper surface through the lead bars;

7.The machine can be combined with automatic printing machine. Through the moving clamps it can build up an automatic producing line: Printing – Drying – Conveying – Stacking.
