Description

Technical Field

[0001] The utility model relates to the technical field of plastic extrusion mechanisms, in particular to an extrusion mechanism of a plastic extruder for processing cables. Background Art

[0002] Cable is an electric energy or signal transmission device, usually composed of several or several groups of wires, and has strong corrosion resistance and fire resistance. After the cable is produced, a plastic extruder is usually required to wrap a plastic layer on its outer wall to protect it. The main machine of the plastic extruder is an extruder, which consists of an extrusion system, a transmission system and an extrusion head. Most existing extruders usually fix the extrusion head and the extrusion system together with bolts. After the extrusion head is disassembled for cleaning or maintenance, when it is installed again, it needs to be manually lifted and then aligned with the discharge port of the extrusion system and then installed. It may be difficult to align it at one time. If the extrusion head is large and heavy, it will be more time-consuming and labor-intensive.

[0003] A search was conducted to find out the above-mentioned problems. In the currently disclosed prior art, for example, an extrusion mechanism of a plastic extruder for processing cables proposed in publication number CN216609968U is implemented by fixing a mounting ring on an extrusion head and then installing a fixing ring on a screw. The fixing ring is placed horizontally with the discharge port of the extrusion system. When installing the extrusion head, the mounting ring is placed in the fixing ring. A positioning rod is installed in the fixing ring. After placement, the mounting ring can be moved by squeezing the positioning rod. The positioning rod is installed in the inner groove of the fixing ring through a spring. If the mounting ring and the fixing ring are misaligned, the positioning rod can be rotated to make a circular motion on the inner side of the fixing ring, so that the positioning rod slides on the outer wall of the mounting ring until the positioning rod is inserted into the positioning hole of the mounting ring.

[0004] However, during positioning, the positioning rod needs to rub against the outer wall of the mounting ring when rotating, so as to find the positioning hole of the mounting ring for insertion. Over time, this may cause wear on the side of the positioning rod, and the wear may shorten the length of the positioning rod. As a result, when the positioning rod is subsequently inserted into the positioning hole, the position of the positioning rod inserted into the positioning hole is shorter, so that the installation of the extruder head may not be secure.
