Background
The high-wear-resistance extrusion strip is used as a sealing element and widely applied in the production process. However, the existing sealing strip is often made of a single material, and in order to have the characteristic of high wear resistance, other properties of rubber are often required to be sacrificed, so that the tensile property of the high wear-resistant extruded strip is relatively poor, and the high wear-resistant extruded strip is easy to break in the using process. In order to overcome the above situation, a composite form of two extruded strips is generally adopted, however, although the composite extruded strips can solve the above problems to some extent, the composite strips are not firmly matched with each other in the using process, and the two extruded strips are separated from each other and cannot achieve the purpose of mutually reinforcing.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a mould of high wear-resisting extrusion strip is exclusively used in, can make two kinds of extrusion strips in the compound high wear-resisting extrusion strip firmly combine each other.
In order to achieve the above purpose, the technical scheme of the utility model is that:
the utility model provides a mould of high abrasion extrusion strip which characterized in that: comprises that
The rear part of the first extrusion head is provided with a first screw pump;
the second extrusion head is sleeved outside the first extrusion head and is coaxially arranged with the first extrusion head, and the rear part of the second extrusion head is provided with a second screw pump;
the utility model discloses a first extrusion head, including first extrusion head, the casing of first extrusion head, the axial is provided with a plurality of clearing holes in the casing of first extrusion head, the rotatable disturbance pole that is provided with in the clearing hole, the one end of disturbance pole stretch out the first discharge end of extruding the head and with be the obtuse angle contained angle between the first clearing hole, the other end and the first drive wheel fixed connection of disturbance pole, the fixed motor that is provided with in afterbody of first extrusion head, be provided with the tangent second drive wheel of an outer fringe and first drive wheel on the output shaft of motor.
Further, the disturbance rod is made of high-strength alloy materials.
Furthermore, the bending angle interval between one end of the disturbance rod extending out of the first extrusion head and the through hole is 120-150 degrees.
Further, the discharge end of the first extrusion head is recessed in the second extrusion head.
The utility model has the advantages that: 1. when the two kinds of rubber are extruded, the disturbing rods arranged in the first extrusion head slightly stir the joint surfaces of the two kinds of extrusion strips, so that the joint surfaces of the two kinds of extrusion strips are irregularly wound, and the joint strength of the two kinds of extrusion strips is improved. 2. Adopt high strength alloy material can guarantee the high-efficient rotation of disturbance pole. The included angles of 3.120-150 degrees can ensure the disturbance effect of the disturbance rod on the two extrusion strips and simultaneously ensure the deformation of the two extrusion strips to be minimum, thereby ensuring the integral appearance of the extrusion strips to be attractive. 4. The discharge end of the first extrusion head is recessed in the second extrusion head, so that the outer edge surface of the extrusion strip processed by the disturbance rod can be trimmed by the second extrusion head, and the appearance of the extrusion strip is improved.
