Feeder

The original rear pick-up feeder technology taken from the offset Press, ensures stable and smooth feeding of various types of substrate. Dependant on the substrate, overlapped (stream) or single sheet (universal) fed can be selected easily.

A front pick up feeder is also available and can be used for stable feeding of film and other substrates.

Feed board

The vaccum absorb is assembled in the bottom of the feed board, matching with the push and press paper construction, insure various materials all can be delivered smoothly.

Cylinder and registeration system

Cylinder stops step automatically to ensure the forehead of the printing stock can be sent accurately to the gripper of cylinder, which is up to extreme high precision; at the same time, gripper of cylinder and pul/pushl side-lay both have sensors for supervising if the printing stock is in correct place.

The vacuum cylinder with +/- 0.01mm accuracy across the cylinder surface, a large cylinder shaft and specially made high precision bearings ensure the highest quality printing at higher speed.

Squeegee system (constant squeegee pressure system)

Squeegee and ink return bladeare driven by individual cams and a two-step action cam helps reduce the squeegee shock onto the screen mesh; Due to the positive down cam action, the printing pressure is evenly applied to the cylinder continuously, squeegee with the pneumatically pressure kept device, resulting in sharp dot reproduction, the printing graphics is more clearly and the ink layer is more well-proportioned.

Frame circulate railway

Imported beeline guide and ball bearing, reduce the shake and noisy when the whole machine is working under high speed, insure the stability of printing.

Delivery board

The delivery board can be overturned up to 90degree to allow easy access to the screen mesh for cleaning and adjusting the frame, installing the blade; along with the vacuum adsorption, insure collection smoothly.

Screen Frame System

The screen frame rack can be pulled out, which is easy for adjusting the register or feeding, as well as cleaning the cylinder and screen frame; at the same time, it is assembled with device to hold the ink dropped to avoid the ink drops on the cylinder.

WST-800UVJW UV Curing Machine (Stepless adjustable)

WST-800UVJW is specially designed for using with automatic screen printing machine, offset machine and other equipments. It's widely used for dying,dehumidifying and UV curing etc in the field of screen printing, printing and dyeing,electroplating, electronic circuit board and so on.

Control Panel

Inside Electrical Control Parts

1. Three groups of stepless regulating light source, independent control, digital instrument real-time indication of the working state and service life.

2. Adopt special aluminum magnesium alloy lampshade, focusing design, high production efficiency.

3. Equipped with a reasonable cooling system, two groups of independent lampshade heat dissipation, the lower part of the adsorption system, to prevent the work chamber temperature is too high, resulting in substrate deformation.

4. The conveyor belt automatic correction system with adsorption system, easy to use, more conducive to the paper conveying; imported Teflon (TEFION) mesh belt, high temperature resistance, friction resistance, stable use to ensure long time.

5. Conveyor frequency stepless speed regulation, visual production adjustment, conveying speed, up to 60 meters / min..

The advantages of stepless variable power light source compared with common transformer controlled UV light source:

• Wide energy range output: the output power of the lamp tube is 30% to 100%, stepless adjustable;
• High power conversion rate: about 20% higher than traditional transformer drive UV energy, and can effectively extend the lamp life;
• High efficiency, energy saving and environmental protection: effectively reduce the loss and reactive power of traditional transformers, save about 40% of the power consumption compared to the same year;
• Comprehensive intelligent protection: more than 20 professional protection alarm mechanism, such as overheating of tube, parameter error of lamp tube, disconnection of lamp tube, etc.;
• High intelligent power adaptation: standby settings, no material input, 30% power standby; the material is in, within 0.5 seconds automatically to set the power;
• The perfect use of safety: avoid the traditional transformer heating and wiring complex caused by security risks.

WST-800S Full automatic stacker can combine with full-automatic cylinder type screen press and all kinds of dryer together to collect the paper and make them in order automatically.

1. The whole machine is controlled by PLC, collecting printing substrate and making the paper in order automatically.
2. Photoelectricity monitoring,two sides of baffles run when the paper come into the plate.
3. Paper conveying system is controlled by inverter with stepless speed regulation and conveyor belt guide the idler wheel to feed the paper.
4. Pneumatical elements control the jogger action, which avoid paper to be broken or other damage.
5. Following all kinds of paper size, paper jogging device can be adjusted from back, left and right easily and conveniently.
6. Induction sensor make the stacking board down automatically and keep paper collect smoothly.
7. Paper stacker has limitation safety mechanism at up and down position to avoid the machine from damaged.
8. Paper jam and paper pile height supervision and make the printing press stop in-line.
9. Connected with the printing part which can control the printing part's running.
10. Paper counting function.
