Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesives, in particular to a cooling device for hot melt adhesive water cooling tank production. Background Art

[0002] Hot melt adhesive is an adhesive that melts and becomes sticky when heated. It usually comes in stick or granular form and needs to be heated using a hot melt glue gun or hot melt glue stick.

[0003] When hot melt adhesive is heated to a certain temperature, it becomes liquid and can be applied to the surface of the object to be bonded. After the hot melt adhesive cools, it will harden quickly to form a strong bonding effect.

[0004] Hot melt adhesive has many advantages, such as fast curing, strong adhesion, and easy use, so it is widely used in many fields, such as handicrafts, home repairs, industrial production, etc. However, the heat resistance and weather resistance of hot melt adhesive are relatively weak, and it is not suitable for use in high temperature or harsh environments.

[0005] A relatively common hot melt adhesive auxiliary product is the hot melt glue stick: a hot melt glue stick is an adhesive used in conjunction with a hot melt glue gun. It usually exists in the form of a plastic stick or a rubber stick and becomes liquid after heating. Hot melt glue sticks can be divided into general type, low temperature type, high temperature type, transparent type, etc. according to their ingredients and uses.

[0006] There are also hot melt glue pellets: hot melt glue pellets are a kind of granular hot melt glue, suitable for hot melt glue guns or other heating equipment. The composition and performance of hot melt glue pellets are similar to those of hot melt glue sticks, but the shape is easier to store and transport.

[0007] At present, hot melt adhesive products need to be quickly cooled and shaped during extrusion molding, and most of the shaping methods are to directly put the hot melt adhesive products into the cold water of the cold water tank after extrusion or processing. Basic shaping can be achieved through water cooling. However, since production is continuous, if the cold water in the cold water tank continues to cool the continuous flow of hot melt adhesive products, the temperature of the water itself will also rise. Therefore, it is necessary to design a cold water tank to additionally cool the cold water to ensure the normal cooling use of the hot melt adhesive water cooling tank. Utility Model Content
