Problems solved by technology
[0003] 1. After the rubber material is extruded from the extruder, the rubber coating formed on the surface of the steel wire passing at high speed does not meet the thickness requirements;
[0004] 2. The rubber coating on the surface of the steel wire is not uniform enough to meet the needs of use;
[0005] 3. Due to the uneven rubber coating on the surface of the steel wire, it is easy to have copper exposed on the rubber particles. At this time, the steel wire will directly contact the tape wound on the outside, which will reduce the adhesion of the traveler during the vulcanization process.

Embodiment Construction
[0028] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0029] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, the present invention proposes a steel wire rubber-coated extruder head assembly, including a flow channel body 1 and a connecting body 2. Based on the analysis of the shortcomings of the prior art, the present invention opens a section in the middle of the flow channel body 1. Damping installation hole 6, and in damping installation hole 6, damping block 3 is installed with interference, and several second via holes 4 are opened on damping block 3, and steel wire can pass through from second via hole 4, and damping block 3 simultaneously There is a rubber increasing hole 5 on the top, and the rubber increasing hole 5 corresponds to the second via hole 4 and is connected to each other. There is a gap between the rubber increasing hole 5 on the damping block 3 and the damp...

The invention relates to a steel wire glue coating extruder head assembly. The assembly comprises a runner body and a connecting body and further comprises a damping block, the damping block is embedded in the runner body, a plurality of second via holes are formed in the damping block, steel wires can penetrate through the second via holes, glue adding holes in one-to-one correspondence with the second via holes are further formed in the damping block, and the glue adding holes penetrate through the damping block and are communicated with the second via hole. The steel wire glue coating extruder head assembly is provided with the damping block, the glue adding holes and a streamline guide inclined plane are arranged on the damping block, and a steel wire can be coated with glue for many times, so the glue coating degree is sufficient and uniform, and the problem that glue particles expose copper is solved; and meanwhile, the damping block and a mouth-shaped block are split, and size machining can be conducted on a certain assembly, so the assembly is more flexible and convenient to use.
Description
technical field [0001] The invention belongs to the technical field of steel wire rubber-coated technology, in particular to a steel wire rubber-coated extruder head assembly. Background technique [0002] The steel wire rubber coating process refers to the all-round wrapping of rubber on the steel wire, which is an important link in the tire production process. At present, the extrusion method is mostly used in the steel wire rubber coating process, and the existing extrusion head When covering glue, there are the following problems: [0003] 1. After the rubber material is extruded from the extruder, the rubber coating formed on the surface of the steel wire passing at high speed does not meet the thickness requirements; [0004] 2. The rubber coating on the surface of the steel wire is not uniform enough to meet the needs of use; [0005] 3. Due to the uneven rubber coating on the surface of the steel wire, it is prone to the phenomenon of exposed copper on the rubber p...
