Embodiment 1

[0028] The invention provides a multi-mode head for twin-wire extrusion, such as figure 1 As shown, the multimode head includes:

[0029] Extrusion screw 1 is used to plasticize the melted rubber and extrude the rubber to the rubber distribution system 2; the rubber is plasticized and melted in the extrusion screw 1, which is convenient for multi-mode extrusion;

[0030] The rubber material distribution system 2 is connected with the extrusion screw 1, and is used to controllably distribute the rubber material to the first runner 3 and the second runner 4; the rubber material is distributed through the rubber material distribution system 2, which can increase the amount of rubber material Extrusion productivity;

[0031] The first flow channel 3 is set on the machine head body 5 and communicates with the rubber material distribution system 2 for receiving the rubber material distributed by the rubber material distribution system 2; the second flow channel 4 is set on the mach...

Embodiment 2

[0045] The present invention provides a double-line extrusion method for a multi-mode die, which is applicable to the multi-mode die as in Embodiment 1, such as Image 6 As shown, the two-wire extrusion method includes:

[0046] Step S1, the rubber material is plasticized and melted by the extrusion screw 1, and then enters the rubber material distribution system 2 through the honeycomb plate 101 and the filter screen 102 of the flange 10; the honeycomb plate 101 is used to make the rubber material uniform; the filter screen 102 is used for filtering Remove large particles of rubber to make the particle size of the rubber smaller. Therefore, the technical effect of reducing the energy consumption of the multi-mode handpiece can be achieved.

[0047] Step S2, the rubber distribution system 2 controllably distributes the rubber to the first flow channel 3 and the second flow channel 4; distributing the rubber through the rubber distribution system 2 can improve the production e...

Abstract

The invention discloses a multi-die machine head for double-line extrusion and an extrusion method thereof, and the multi-die machine head comprises an extrusion screw rod, a rubber material distribution system, a first runner, a second runner, a first die hole and a second die hole. The extrusion screw rod is used for plasticizing and melting a rubber material and extruding the rubber material to a rubber material distribution system. The rubber material distribution system is connected with the extrusion screw rod and is used for controllably distributing the rubber material to the first runner and the second runner. The first runner is formed on a machine head body, is communicated with the rubber material distribution system and is used for receiving the rubber material distributed by the rubber material distribution system. The second runner is formed on the machine head body, is communicated with the rubber material distribution system and is used for receiving the rubber material distributed by the rubber material distribution system. The first die hole is communicated with the first runner and is used for receiving the rubber material conveyed by the first runner and extruding the rubber material to a cable core. The second die hole is communicated with the second runner and is used for receiving the rubber material conveyed by the second runner and extruding the rubber material to the cable core. The production efficiency of the extruder head is improved.

Description

technical field [0001] The invention relates to the technical field of cable extrusion, in particular to a multi-mode head for twin-line extrusion and an extrusion method thereof. Background technique [0002] Cable extrusion is a necessary process in the production process of wires and cables. With the advancement of engineering technology, the requirements for wires and cables at different engineering sites have also increased, such as waterproof, anti-static, etc., and the demand for wires and cables is large. It is required that work efficiency should be further improved. [0003] In the prior art, the extrusion head of the power cable generally adopts the extrusion form of a single specification and a single mold. Each extrusion equipment is equipped with a head and a set of molds, and only one specification can be extruded at a time. [0004] This solution has the following defects: 1) it occupies a large space; 2) the production efficiency is low; 3) the energy consu...
