Description

TECHNICAL FIELD

[0001] The utility model relates to waterproof roll production technical field especially relates to an extrusion device with water cooling function for waterproof roll production. BACKGROUND

[0002] Waterproof roll material is mainly used for building walls, roofs, tunnels, highways, landfills and the like, and can resist external rainwater and groundwater seepage. It is a flexible building material product that can be rolled into a roll. It is a leak-proof connection between the engineering foundation and the building, and is the first barrier of the entire engineering waterproofing. It plays a crucial role in the entire project. There are many types of waterproofing rolls. In order to make the waterproof roll have multiple properties, the waterproof roll is composed of multiple fabrics. The commonly used self-adhesive waterproof roll is formed by extruding the waterproof roll after the outer hydrophobic isolation film and the waterproof layer roll are glued together.

[0003] The patent number CN213137737U discloses a waterproof roll production equipment. The water cooling equipment increases the speed of forming the waterproof roll. The cutter cuts a hydrophobic groove on the surface, saving production procedures and speeding up production efficiency.

[0004] The above-mentioned device can only produce single hydrophobic isolation layer roll. However, when processing the composite waterproof roll, the two layers of the roll are glued and combined. Due to the point spraying of glue, the glue is not evenly applied, and the amount of glue is too much or too little. Too much and uneven glue can easily cause bubbles inside the roll. Too little glue can reduce the bonding effect, thereby affecting the quality of the waterproof roll. UTILITY MODEL CONTENTS
