M-80250XIR IR tunnel oven

Introduction

     The tunnel drying furnace is a device that fixes the drying unit on the top of a tunnel-like tunnel, and the product is slowly dried through the drying unit along the conveyor belt. Due to the continuous transportation of the product, the drying efficiency is significantly improved. It cooperates with pad printing machines, screen printing machines, and paint spraying equipment to dry the product uninterruptedly.

High drying efficiency: The tunnel drying furnace can set stable parameters such as temperature and wind speed to allow the printed product to be continuously heated during the transmission process, thereby accelerating the evaporation or curing reaction of the solvent in the ink.

Uniform drying effect: The temperature field in the furnace is relatively uniform, and the printed product moves at a uniform speed in the tunnel, so that the ink at each position can be radiated with consistent heat.

High degree of automation: It can be connected with the printing production line to achieve continuous operation from printing to drying.

Usage

     The tunnel drying line is suitable for drying solvent-based inks after pad printing and screen printing. The printed products are placed on the conveyor belt, which will drive the products into the drying system. The infrared rays generated by the drying system generate heat, which is radiated to the ink surface, accelerating the volatilization of the solvent in the ink, so that the ink quickly adheres to the surface of the product.

The tunnel drying line can be used alone, and the products can be placed on the conveyor belt manually, or the products on the pad printer or screen printer can be automatically transferred to the conveyor belt using a robot.

The temperature and speed of the tunnel drying line can be set to suit different products and printing processes. Generally, the tunnel drying line is not a standard product. It must be customized according to the user's requirements. The customized parameters include the width and length of the conveyor belt, the material of the conveyor belt, the number and power of the heating tubes, etc.

Use of IR tunnel drying furnace

• Pad printer + IR tunnel drying furnace

When the pad printer uses solvent-based ink, it can be used in combination with a tunnel drying furnace. The drying furnace can accelerate the volatilization of the solvent in the ink and improve production efficiency. The tunnel drying furnace can be used alone or installed on the pad printer. The pad printing ink dries faster, and the temperature of its tunnel drying furnace can be lower.

• Screen printer + IR tunnel drying furnace

Screen Printers can also use solvent-based inks, especially glass printing, some plastic products printing, and some paper printing. The screen printer and the tunnel drying furnace can quickly dry the ink. Due to the fast printing speed of the screen printer, the tunnel drying furnace used by the screen printer generally requires a longer length and a higher temperature. The screen printer and the tunnel drying furnace usually need to be seamlessly connected with a feeding manipulator to improve production efficiency.

• Clothing screen printer + IR tunnel drying furnace

Clothing screen printer is a special turntable screen printer, which is shaped like an octopus. Clothing mainly uses various solvent-based inks and various glues. The drying method is hot air drying. The use of a tunnel drying furnace can accelerate the curing and drying of the ink.

RFQ

• What is infrared?

Infrared is an electromagnetic wave with a wavelength longer than visible light and cannot be seen by the naked eye. The sun and flames contain infrared. The most notable feature of infrared is the thermal effect. Infrared is converted into heat after being absorbed by an object.

A considerable part of printing inks are solvent-based inks. Only when the solvent evaporates from the ink can it be completely dried on the surface of the object. According to the principle of solvent volatilization, wind and heat are important external conditions to accelerate the volatilization of the solvent. Therefore, forming a stable heat unit in a special space can accelerate the drying of the ink. Theoretically, any physical object with a temperature above absolute zero can emit infrared.

The thermal effect of electricity in the industrial field is the main basis for generating infrared. Closet-type industrial ovens and tunnel-type assembly line ovens use the thermal effect of electricity. When the heating tube is powered on, the infrared generated can be radiated to the surface of the object.

• Characteristics of infrared:

High heating efficiency: The wavelength of infrared is close to the natural frequency of the molecular vibration of the object, and can be directly absorbed by the ink and converted into heat energy. The heating speed is fast and uniform.

Precise temperature control: By adjusting the emission intensity of infrared rays, the heating temperature can be controlled more accurately, which is suitable for temperature-sensitive materials such as plastic films.

Good penetration: It can penetrate objects of a certain thickness and start heating from the inside of the ink.

At present, closet-type ovens and tunnel-type ovens are widely used in the drying of pad printing inks and screen printing inks, and play an important role in manufacturing enterprises in conjunction with pad printing machines, screen printing machines and spraying equipment.
