Product Description

Tunnel drying furnace for pad printing, silk screen printing, and clothing printing and oil spraying:

Function and use

The tunnel drying furnace is mainly designed for drying after pad printing, silk screen printing, clothing printing, and oil spraying. After pad printing is completed, the pad printing ink can be quickly dried to allow the pattern to be firmly attached to the object; for silk screen printing, the solvent in the ink or coating used for silk screen printing can be evaporated to ensure the lasting printing effect; for clothing printing, whether it is water-based or oily printing materials, it can be effectively dried through it to avoid fading and smudges in the printing; after the oil spraying process, the sprayed paint layer can be quickly dried and fixed.

Tunnel structure features

The tunnel structure is adopted. The objects enter from one end of the tunnel and move slowly along the internal track. The drying process is gradually completed during the movement, and finally output from the other end. This structure can realize continuous and assembly-line drying operations, greatly improving production efficiency. It is suitable for batch processing of products after printing, oil spraying and other processes, such as a batch of clothing or a batch of small objects that have been pad printed or silk screen printed.

Drying principle and advantages

Through built-in heating devices, such as electric heating wires, infrared heating tubes, etc., the air inside the tunnel is heated to create a high-temperature environment, thereby accelerating the volatilization of solvents contained in inks, coatings, paint layers, etc. and promoting their rapid drying and curing. Moreover, the temperature distribution inside the tunnel drying furnace can be relatively uniform, which can ensure that all parts of the items can get a relatively consistent drying effect, making the quality of the printed and sprayed patterns or coatings more stable and reliable.

Matching adaptability

As a supporting equipment, it can be well connected and coordinated with pad printers, screen printers, clothing printing equipment and spray equipment. According to different production speeds, product types and other actual conditions, the drying temperature, the speed of movement of items in the tunnel and other parameters can be flexibly adjusted to ensure that they match the rhythm of the front-end printing and spraying processes, ensure that the entire production process is smooth and efficient, and meet the drying needs of various printing and spraying processing production.

High Drying Efficient- heated with far-infrared ceramic heating rod and hot wind circuit make printed object dry evenly in the shortest time. Thus save power; Heatproof conveyor belt- telflon coated conveyor belt can work properly and durable in high temperature. Conveyor speed controllable- The conveyor is driven by stepless change speed motor. Therefore, running speed of conveyor can be set arbitrary, Thus, The dryer can dry different thickness object. Cover openableheating room- openable covers on both side of heating room. Ceramic heating rod can be easily replaced by simply opening the cover of heating room. Wide range and precision temperature control- Heating temperature can be set to any temperature between roon temperature to 300 degree. Tolerance of temperature is in +/-5 degree.

Summary︰
Ink drying is an important indicator to measure the printing quality. The more common ways of ink drying are heat drying and UV drying. Heat drying is the drying method of solvent-based ink. In order to maintain the continuous delivery of products, the most common way to dry solvent-based ink is to use a tunnel furnace for processing. The tunnel drying furnace consists of a conveyor belt that can circulate and a device that can generate infrared rays. Composition, the product will be placed on the conveyor belt, driven by the motor, the conveyor belt will be transported to the infrared lamp at a constant speed to receive irradiation, and the solvent in the ink will be evaporated and sent to the outside.
Tunnel dryer can be connected with pad printing machine, screen printing machine, widely used in various types of plastic, glass, and clothing printing industries.
