[0002] Extruder is a type of plastic machinery. According to the direction of the material flow in the die and the angle between the center line of the screw, the die head can be divided into right-angle die head and bevel die head. Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and rare multi-screw extruders and screwless extruders. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material, and form it through the die. The extrusion head of a traditional extruder is often fixed by multiple bolts, so the staff needs to assist the extruder head to align the bolt holes, which is not convenient for the quick installation of the extruder head, greatly reducing the work efficiency of the staff in installing the extruder head.

[0008] As a further solution of the utility model: one end of the clamping plate is threadedly connected to the screw rod, the other end of the clamping plate is slidably connected to the slide rod, the clamping plate is overlapped on the connecting ring, and the connecting ring, the bearing member and the fixing block are all fixedly connected to the extruder head body.

[0009] As a further solution of the utility model: the positioning ring is fixedly connected to the extruder body, the head is installed on the extruder body, and the positioning ring is sleeved on the head, the extruder head body is installed on the head, the wire wheel is plugged into the fixed block, and one end of the rotating part is fixedly connected to the wire wheel.

[0010] As a further solution of the utility model: a groove is provided on the fixed block, and the insertion rod is slidably connected to the groove, one end of the reset spring is fixedly connected in the groove, and the other end of the reset spring is fixedly connected to the insertion rod, the two ends of the traction wire are respectively fixedly connected to the insertion rod and the wire wheel, the fixed block is inserted into the positioning ring, and the insertion rod passes through the fixed block and is inserted into the positioning ring, and the reset spring is sleeved on the traction wire.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The cable extruder has an extrusion head with a positioning function. By rotating the rotating piece on the bearing part, the wire wheel is driven to rotate, and the plug rod is pulled to shrink by the cooperation of the traction wire, and the fixing hole is inserted into the positioning ring. Then the rotating piece is loosened to insert the plug rod into the positioning ring, so that the extruder head body is installed on the machine head, and then the motor is started to rotate the screw rod, and the clamp is fixed to the connecting ring on the extruder head body through the cooperation of the sliding rod, thereby greatly improving the installation efficiency of the extruder head.

[0013] 2. The cable extruder has an extrusion head with a positioning function. When the finished cable is just produced from the extruder body, the temperature of the finished cable body is often high, and the plastic protective layers on the finished cable body are easy to stick to each other, which is inconvenient for the winding of the finished cable. Therefore, by starting the fan on the cooling box, the cable on the top of the ventilation plate is initially cooled down. The cooperation between the cooling box and the ventilation plate effectively avoids accidental injury to the operator during the operation of the fan, thereby greatly improving the practicality of the extruder head.
