Description

Light spool

Technical Field

The utility model belongs to the technical field of spool, and particularly relates to a light spool.

Background

The spool is a tool used to wind wire or rope. The specification and the material of the spool are different according to the different materials and specifications of the wound wire rope. The spool for winding the steel wire is generally of a steel plate structure, but a wooden spool can be used for winding the thin steel wire and the nonferrous metal wire. The use of plastic spool is increasing.

Because the hardness requirements of the wound metal wires and the steel wire ropes on the spool are higher, the common spool is made of a vehicle metal piece, and the spool meets the hardness requirements of most of the wound metal wires on the market, but has the advantages of heavy weight, high cost, easy rusting of metal and shorter service life. At present, wooden and plastic spool wheels are gradually introduced, but the wooden spool wheels are easy to leave impressions when being wound, and the spool wheels made of common plastic cannot meet the hardness requirement of some metal wires, so that the spool walls must be thickened, and the quality is increased.

Disclosure of Invention

Based on the above-mentioned problems existing in the prior art, an object of an embodiment of the present application is to: there is provided a lightweight spool, which is provided with a spool,

the application provides a light spool, which comprises a wheel shaft and two side plates, wherein the side plates are arranged on two sides of the wheel shaft, the wheel shaft is hollow and cylindrical, and the side plates are annular; the wheel shaft and the two side plates are integrally made of PPS B4300G9LW-T8BK, are 55% glass fiber reinforced high-temperature-resistant high-strength high-modulus polyphenylene sulfide (PPS) composite material, and have the advantages of high temperature resistance, low warpage, good fluidity, high mechanical strength, high bending modulus, excellent chemical resistance and high cost performance; the structure of thin-wall products such as computer panels and mainboards has wide application in the fields of electronics, industrial accessories and the like.

Further, the inner diameter of the wheel axle is 150mm, and the thickness is 8-9 mm.

Furthermore, a circle of grooves are formed in one surface of the side plate, facing the outer side, of each circle of grooves, and inserts are oppositely arranged on each circle of grooves so as to facilitate subsequent die repair and die modification.

Furthermore, the spool is integrally formed by adopting an injection molding process, the formed plastic part is low in manufacturing cost, light in weight, convenient to transport and store, and low in maintenance cost, and compared with a metal part, the spool is free from rust.

Compared with the prior art, the utility model has the following beneficial effects: the spool is made of PPS B4300G9LW-T8BK integrally, and compared with the existing spool, the spool is low in overall weight, low in manufacturing cost and convenient to transport, strength requirements of winding 760KM can be met, the spool is not easy to deform during use, cracking or bursting of the spool when winding is measured is prevented, and service life of the spool is greatly prolonged.
