Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to an XPE foam extruder with an extended structure. Background Technology

[0002] An XPE foam extruder is a specialized piece of equipment for producing XPE (chemically cross-linked polyethylene) foam. Through a specific process, low-density polyethylene (LDPE) is mixed with coupling agents and foaming agents, and then foamed at continuous high temperatures to form a closed-cell structure of chemically cross-linked polyethylene foam. This foam material is widely used in various fields such as automobiles, air conditioning insulation, sports facilities, precision instrument packaging, and sports protective equipment due to its excellent performance.

[0003] Utility model patent with authorization announcement number CN202221910496.2 discloses a low-noise inorganic pearl cotton foaming machine with a noise reduction mechanism. The low-noise inorganic pearl cotton foaming machine with a noise reduction mechanism includes a machine box, a die head with an extrusion groove installed at the front of the machine box, an upper cover set on the upper side of the die head, and a lower cover set on the lower side of the die head. A bracket is set at the front of the machine box. Sound-absorbing cotton is installed on the inner walls of the upper cover and the lower cover. An arc-shaped concave support groove is set at the upper end of the bracket. The support groove is on the same horizontal line as the die head. Rotatable balls are installed in a row at the bottom of the support groove. This utility model discloses a low-noise inorganic pearl cotton foaming machine with a noise reduction mechanism. The semi-circular upper and lower baffles are connected to form a closed structure that surrounds the outside of the die head and the support, reducing the noise generated when the material is extruded from the die head and spreading directly to the surroundings. When used with sound-absorbing cotton, the noise propagating inside the baffle is quickly absorbed, further reducing the noise. When the formed pearl cotton is pulled by the roller mechanism, it is dragged in the support groove. The rotatable balls attached to the surface of the pearl cotton reduce the noise generated by the sliding friction between the pearl cotton and the support.

[0004] Although the low-noise inorganic pearl cotton foaming machine with noise reduction mechanism has the advantage of noise reduction, the device still has the following problems in the production process: the device directly blows airflow onto the freshly extruded product through a blower fan, and the extruded product is still at a high temperature. Since the airflow is not filtered, the airflow will bring dust and other impurities from the environment onto the product, which will seriously affect the molding quality of the product. In view of this, we propose an XPE foam extruder with an extension structure. Utility Model Content

At this time, the fans on both sides run and blow air into the housing. When the air passes through multiple dust filters on both sides, the air is filtered and purified. The purified air is then blown onto the foam through multiple air outlets. Under the blowing of the air, the foam can be quickly cooled and shaped. This design not only facilitates the rapid cooling and shaping of the foam, but also avoids the contamination of the foam by dust and other impurities, ensuring the molding quality of the foam.

[0020] 2. With the cutting component, when the foam enters the tube, the rotating cutter can cut the foam. This design has the advantage of being easy to operate and meets the processing requirements of foam. Attached Figure Description
