UST-105GS Automatic High Speed Spot UV Coating Machine 

INTRODUCTION

This is a high-performance high-speed spot/full UV coating equipment with the characteristic of being applicable to both water-based and UV coating materials, which can fully meet various coating requirements. It is suitable for spot or full coating using rubber blankets or flexible resin plates as the printing plates.


The machine adopts a swing-down structure to complete the paper transfer, making the paper handover more precise and efficient. The impression method uses a double-diameter structure, and its efficiency is twice that of traditional coating machines. When performing spot coating, the registration is accurate, the coating is even, and there is no ink squeezing phenomenon.

It is used for the spot overprinting or full coating of the text and patterns of various printed products such as books, milk cartons, color boxes, films, and high-end packaging, which can protect the surface of the printed products and enhance their aesthetic appeal.


The paper transfer method of the machine adopts full-length gripper bar transfer, and the chain is fully enclosed to reduce stretching, greatly improving the durability of use. With a number of carefully designed safety protection measures and a user-friendly operating system, the entire production process is made safe and easy to learn. This machine can achieve high-speed and stable production at a speed of 10,000 sheets per hour.

  • Feeding system

    • The feeder adopts a high-speed feeder head with four pick up and four feeding suckers. It is a highly efficient paper feeding. Its unique maintenance-free design endows it with stronger and more stable paper feeding. While running at high speed, it can ensure that each sheet of paper is accurately and swiftly transported, significantly reducing errors and delays during the paper feeding procedure.


    • It can be equipped with a shaftless drive mode, which breaks away from the limitations of the traditional shaft system. This makes the paper feeding more smoothly and reduces the mis-feeding caused by mechanical wearing. At the same time, this technology also enhances the adaptability of the equipment to different paper specifications and materials. Whether it is thin paper or thick cardboard, the paper feeder can handle them easily. This paper feeder has the advantages of simple operation, low maintenance cost, stable and reliable performance, etc.


  • Coating system

    The UV drying equipment is consist of two（Optional 3pcs） pull-out type 

    UV mercury lamps, which can quickly cure the UV varnish and make 

    it more convenient to replace the lamp tubes.


    The control system adopts the full-computer stepless curing technology. 

    The power of the UV lamps is automatically matched with the machine speed, 

    so as to achieve high efficiency and energy conservation.


    An automatic temperature control device is installed inside the lamp cover. 

    If the temperature exceeds the value set by the system, the lamp group will 

    be automatically turned off to avoid damaging the lamp cover due to overheating.


    The system is equipped with an IR drying lamps, which is consist of 30 IR lamps 

    and is controlled separately in three groups, and it is used for drying 

    water-based consumables.


    The chain gripper mechanism use closed gripper bar under the curing zone, 

    maintaining perfect registration even at maximum production speeds.


  • Drying system

    The left and right side lays adopt a bearing-type design, which is convenient to adjust and provides precise positioning. Meanwhile, it has the function of fine adjustment left and right.


    The front lay features an independent and adjustable design. It allows for fine adjustment of the front lay during the production process, which greatly facilitates the registration of spot UV.


    The lubrication system of the main machine adopts a rain-falling type lubrication method. It doesn't require special maintenance. When the lubricating oil in the main machine's oil circuit is insufficient, the system will automatically alarm and stop the operation of the main machine.


    The equipment transmission utilizes a high - strength external helical gear structure, which has the advantages of low operating noise, simple maintenance.


    The coating roller has a ceramic anilox roller with a closed - type doctor blade system. This combination enables precise control of the amount of coating material, effectively reducing the splashing of consumables. (A rubber roller + steel roller structure is optional.)


    The equipment is equipped with all imported bearings and chains, ensuring more stable operation of the entire machine and enhancing its durability.


    Safety protection devices are configured in multiple locations, effectively ensuring the safe operation of the machine by operators.


  • Delivery system

    The mechanical cam flapping system, simple adjustment and guarantees smooth, precise paper stacking.With cooling fans, air-conditioning cooling system is optional.


    A paper slow down suction unit is installed at the delivery, reduce the running speed of sheets at stacker.


    With an integrated sheet counter that monitors production volume in real time and allows manual reset when needed.


    With a cam-driven gripper mechanism, enabling precise sheet registration control while running.

    Equipped with a pneumatic sampling system, providing enhanced safety and simplified operation for sample picking up.
