Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of decorative paper drying, and specifically relates to a decorative paper glue dipping drying equipment. BACKGROUND

[0002] The decorative paper glue dipping drying is a key link in the production process of decorative paper and is mainly used for improving the wear resistance, water resistance and decoration performance of the decorative paper. However, the traditional decorative paper glue dipping drying equipment has the following disadvantages:

[0003] Low drying efficiency:

[0004] The traditional drying equipment usually adopts natural air drying or simple hot air drying, and the drying speed is slow, which cannot meet the needs of large-scale production. Especially after the decorative paper is dipped in glue, the water content is high, and a long time is needed for complete drying.

[0005] Serious energy waste:

[0006] During the operation of the traditional hot air drying equipment, the utilization rate of hot air is low, and a large amount of hot air is directly discharged to the outside, resulting in energy waste. At the same time, the heat preservation performance of the equipment is poor, and the heat loss is fast, which further reduces the energy utilization efficiency.

[0007] Unstable glue dipping process:

[0008] The traditional glue dipping equipment usually adopts manual or simple mechanical devices to add glue, and the amount of glue liquid and the liquid level cannot be accurately controlled. This may cause uneven glue dipping and affect the quality of the decorative paper.

[0009] Therefore, it is necessary to provide a decorative paper glue dipping drying equipment to solve the above problems. UTILITY MODEL CONTENTS
