Description

Technical Field

[0001] The invention relates to the technical field of textiles, in particular to a yarn roller assembly. Background Art

[0002] At present, the yarn roller assembly is used to wind a large number of spinning threads. Therefore, the structure of the yarn roller itself needs to be very strong to withstand the binding pressure of the spinning thread on the yarn roller. In order to save processing costs, the yarn roller usually uses a bar material as a blank, and the outer cylindrical side of the blank is turned by a lathe to obtain the finished product. Therefore, the previous yarn roller is a solid material, which is not only heavy, but also has a high material cost. Summary of the invention

[0003] The purpose of the present invention is to provide a hollow aluminum alloy yarn roller assembly with high structural strength, light weight and material cost saving.

[0004] The object of the present invention is achieved as follows: A hollow aluminum alloy yarn roller assembly comprises a long strip-shaped reference square tube with a square cross section, and also comprises four hollow modules detachably mounted on four sides of the reference square tube, wherein the hollow modules are hollow shell-like structures;

[0005] The length of the hollow module is consistent with the length of the reference square tube, and the side of the hollow module that is in contact with the reference square tube is a flat structure, and an arc surface is provided on the outer side of the hollow module. The four hollow modules are spliced ​​with each other, and the arc surfaces of the four hollow modules together constitute an outer peripheral surface for winding and binding yarns;

[0006] A cylindrical mandrel coaxially disposed in the reference square tube and coaxial with the outer peripheral surface, and two pairs of oblique reinforcing ribs quasi-symmetrically arranged with the central axis of the mandrel disposed in the reference square tube, one end of the oblique reinforcing rib connected to the outer peripheral side of the mandrel, and the other end of the oblique reinforcing rib connected to the top angle side of the reference square tube;

[0007] The reference square tube, core rod, oblique reinforcing ribs and hollow module are all made of aluminum alloy.

[0008] Compared with the prior art, the beneficial effects of the present invention are: first, the structural strength is high, the outer side of the hollow module is provided with an arc surface, and the hollow module is a hollow shell structure, which can withstand the winding pressure of the spinning line; second, the four hollow modules can be removed and replaced with different specifications as needed, and since the four sides of the reference square tube are used as the installation reference, it is convenient to disassemble and assemble the four hollow modules; third, since the reference square tube, core rod, oblique reinforcement ribs, and hollow module are all made of aluminum alloy, and the main components of the reference square tube and hollow module are all hollow structures, the assembly is light in weight and can save material costs.

[0009] As a further improvement of the present invention, each hollow module is further equipped with a plurality of countersunk screws made of aluminum alloy, the hollow module is further provided with a countersunk hole for inserting the head of the countersunk screw, the reference square tube is provided with a threaded hole, the threaded portion of the countersunk screw passes through the hollow module and matches with the threaded hole of the reference square tube, so as to facilitate installation.
