Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the drawings.

[0019] The special head of the present invention refers to the part between the end of the screw of the extruder and the mouth of the extruder. The special head of the extruder is the key component of the molding of the thermoplastic material. The melt of the extruder is rotated by the screw through the head. The flow state is transformed into a single straight flow state. At the same time, the plastic melt is further plasticized by the temperature control of the heating system, and then the compression ratio is adjusted to generate the required strip molding pressure, which increases the plastic extrusion strip The compactness improves the strength and toughness of the material belt. The continuous material belt with the required rectangular section is obtained through the die, and then wound into a plastic cylindrical tank according to the required diameter.

Abstract

The invention relates to a thermoplastic plastic extrusion strip dedicated head which comprises a connector, a nozzle and a head. The connector has a connection hole. One end of the connector is connected with an extruder, and the other end of the connector is connected with the nozzle. A nozzle hole is arranged in the nozzle. One end of the nozzle is inserted into the connection hole of the connector, and the other end of the nozzle is connected with the head. A distributor is connected with the nozzle inserted inside the connection hole. The head has a discharge hole which is communicated with the nozzle hole. A regulator is also connected on the head. The regulator is arranged next to the discharge hole. The thermoplastic plastic extrusion strip dedicated head provided by the invention has advantages of compact structure, reasonable size, beautiful appearance, low melt flow resistance, easy processing, low cost, installation convenience, dismounting flexibility and simple operation.

Description

Technical field [0001] The invention relates to a special head of an extruder used for extruding and winding a cylindrical tank of thermoplastics, and belongs to the field of machinery. Background technique [0002] The existing die structure is not compact, and the melt flow resistance is large. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a special die for thermoplastic plastic extruded material belt with compact structure, low melt flow resistance and easy processing. [0004] The technical solutions to achieve the above objectives are as follows: [0005] A special die for thermoplastic extruding tape, which is characterized in that it includes a connecting body, a nozzle, and a die. The connecting body has a connecting hole. One end of the connecting body is connected to the extruder, and the other end is connected to the nozzle. The nozzle has a nozzle hole. One end of the nozzle is inserted into the connecting hol...
