Description

Technical Field

[0001] This utility model relates to the field of extruder equipment technology, and in particular to an extruder head for spiral extrusion. Background Technology

[0002] The extruder die head, also known as the extrusion head, is used to shape and extrude raw materials such as rubber and plastics. Extruder dies are also used in the production of plastic granules. However, existing extrusion dies are usually stationary, such as the one disclosed in Chinese patent CN217752683U. These dies utilize the pushing force provided by the feed end to extrude the raw material from the die head, resulting in insufficient stability and a tendency for the extruded product to break or have missing parts. Furthermore, when used for extruding products like plastic granules, the adhesive properties cause the products to stick together and clump in the receiving container, leading to uneven material collection. Therefore, the inventors have developed a new invention. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a spiral extrusion extruder head that has the advantages of high extrusion stability and rotatable extrusion.

[0004] To achieve the above objectives, this utility model provides an extruder head for spiral extrusion, comprising a fixed tube and a feed tube. The fixed tube has a material channel inside, an extrusion die at its bottom end, and an interface at its middle end. The end of the feed tube is fixedly connected to the interface, allowing communication between the feed tube and the material channel. The end of the feed tube also has a through-hole aligned with the material channel. A screw passes through the through-hole and extends into the material channel. A first drive is fixedly connected to the screw at the top of the fixed tube. The fixed tube has a snap-fit ​​part with a snap-fit ​​groove. A first gear is fixedly connected to the extrusion die. A fixed seat extends outward from the snap-fit ​​part, and a second drive that can drive the first gear to rotate is located within the fixed seat.

[0005] Furthermore, the first and second transmissions are respectively connected to drive motors, causing the first and second transmissions to rotate.

[0006] Furthermore, a second gear is provided at the end of the second transmission device, and a third gear is provided between the first gear and the second gear.

[0007] Furthermore, a connector is provided at the other end of the feed tube, and a collar is provided on the connector.

[0008] Furthermore, a plug is provided at the connection between the first actuator and the screw.

[0009] Beneficial effects: compared with the prior art, the extruder head of the spiral extruding extruder has the following advantages: 1, further pushing material through the screw, enhancing the extruding force of the extrusion die, and the extruding and discharging stability is high; 2, the extrusion die can rotate, the extruded formed material is scattered, and the material is uniformly stacked in the container.
