Abstract

The present invention discloses an assembly structure of an I-shaped bobbin for preventing material mixing on a cord car platform, which includes a plurality of wire pay-off shafts on the car platform and a plurality of I-shaped bobbins assembled with the wire pay-off shafts; both the I-shaped bobbins and the wire pay-off shafts are distinguished according to different wire diameters; positioning pin holes with different quantities and positions are provided on the I-shaped bobbins of different specifications, and positioning pins that are correspondingly matched with the positioning pin holes are provided at corresponding positions on the wire pay-off shafts of corresponding specifications; when assembling the I-shaped bobbins, since the positioning pins are provided at different positions on the wire pay-off shafts of different specifications, if the I-shaped bobbins do not match, the assembly cannot be carried out. Therefore, operators can easily carry out the correct assembly of the corresponding type of I-shaped bobbins, avoid the occurrence of material mixing, effectively improve work efficiency and wire quality, and avoid the occurrence of wire misalignment in the cord structure.

Description

Technical Field

[0001] The present invention relates to the field of spool assembly, and particularly to a structure for preventing material mixing in the spool assembly of a cord car platform. Background Art

[0002] In the workshop production of a cord car platform, according to the structure of the cord, there are numerous pay-off shafts and spools on the same car platform, and the types of spools connected are also divided into various types according to the corresponding twisting specifications. Since the spools are relatively similar in appearance, it is difficult to distinguish them. Currently, in the actual workshop production process, different color markings are made on the spools and pay-off shafts for distinction. This distinction method is prone to the problem of misidentification by workers in production tasks with a large quantity, resulting in incorrect pairing of the spools and pay-off shafts, and then affecting the misalignment of the steel wires produced by the cord car platform, thereby affecting the quality and performance of the cord.

[0003] For example, the cord 3 + 9 structure is twisted by 3 pieces of 0.24 and 9 pieces of 0.225. Among them, 3 pieces of 0.24 steel wires are in the middle, and 9 pieces of 0.225 steel wires are on the outer layer; 0.24 / 0.225 uses the same WS9 spool for wet-drawn steel wires. The cord twisting car platform uses 12 identical pay-off shafts, and each pay-off shaft uses a positioning pin to fix the spool. It is very difficult to distinguish several types of spools in the actual production process and it is easy to cause confusion. Summary of the Invention
