Description

Technical Field

[0001] The utility model relates to the field of heat shrink tube manufacturing, in particular to a heat shrink tube extruder. Background Art

[0002] Heat shrink tube extruder is a device specially used to produce heat shrink tube. Heat shrink tube is a material that covers objects and forms a protective layer by heat shrinkage. It is mainly made of polyolefin and special additives, and shrinks in volume when heated by heat shrinkage effect.

[0003] For example, a heat shrink tube extruder disclosed in announcement number CN216760744U provides a feeding device to feed the material from the feeding structure into the feeding structure, and uses a driving motor to transport the material. At the same time, the heating layer heats the internal material. The melted material enters the convergence and fusion structure and is discharged from the right end. Then the material enters the extrusion head, and the heat shrink tube is formed by the diverter cone provided in the extrusion head, which greatly improves the practicality of the device.

[0004] However, the device has some shortcomings. When the raw materials enter from the feed port, there is no relevant filtering device, which may cause impurities in the rubber to enter the feeding room and affect the quality of the product. There is no sealing element, which may cause raw material leakage and external dust to enter. When the device is discharged from the extrusion port, a cooling device can be further or pre-set to cool the raw materials. Utility Model Content
