Problems solved by technology

[0003] For a long time, centrifugal cylinders have been made of aluminum alloy materials. Since the spinning production process is an acidic corrosion environment, the removal rate and replacement rate of aluminum alloy centrifugal cylinders due to corrosion and damage has been high, even as high as 75% per year, resulting in high manufacturing costs. , due to damage, it seriously affects the product quality, and even affects the dynamic balance of the centrifugal cylinder under high-speed operation, resulting in flying cylinder safety accidents and injuring employees
[0004] Later, a glass fiber centrifugal cylinder appeared, using glass fiber as a skeleton fiber, then impregnated with resin, and winding to form a glass fiber centrifugal cylinder. Glitch is generated, which greatly affects the popularization and application

Embodiment 1

[0053] The epoxy resin in the centrifugal cylinder is made of resin, curing agent and accelerator in a volume ratio of 100:1:1. When preparing, it is prepared under the condition of workshop room temperature 16°C. First, the accelerator and resin are mixed according to the above ratio Mix well and add curing agent before starting to roll. Mix the prepared epoxy resin and ceramic powder according to the weight ratio of 1:0.4, and add them into the liquid collection tank 300 after the mixing is completed.

[0054] The wire bundle made of carbon fiber passes through the orientation wheel 301 of the sump 300, then winds around the guide wheel 108 and is wound on the mold base 103. The orientation wheel 301 is immersed in the solution, so the wire bundle through the orientation wheel 301 is The solution is fully impregnated.

[0055] For the convenience of demoulding, the mold barrel 104 is coated with a layer of 1-2mm industrial wax before winding. When winding, the base of the m...

Abstract

The invention discloses a centrifugal cylinder. The centrifugal cylinder is formed by that skeleton fibers are dipped in a resin solution, wound and cured. The resin solution is prepared by proportioning and mixing epoxy resin and a modified material. Optimally, the modified material is one or a combination of ceramic powder, silica sand and marble, and the ratio by weight of the epoxy resin to the modified material is 1:0.4-0.8. The invention further provides a manufacturing method of the centrifugal cylinder. The manufacturing method comprises the following steps: a. preparing winding equipment, wherein the winding equipment comprises a winding die and a liquid collecting trough, and the winding die comprises a die base and a die cylinder; b, preparing a medical solution and carrying out winding pre-preparation; d, demolding, to be specific, carrying out demolding operation after winding is finished for 24hours, and removing the die cylinder; and e, carrying out machining treatment, to be specific, processing a semi-finished blank which is demolded to a product size meeting requirements in a machining mode. The centrifugal cylinder provided by the invention has ultrastrong, wear-resistant and corrosion-resistant properties and effectively improves the layering phenomena of the centrifugal cylinder.

Description

technical field [0001] The invention belongs to the technical field of textile appliances, and in particular relates to a centrifugal cylinder and a manufacturing method thereof. Background technique [0002] The centrifugal cylinder is an important equipment for doffing in the manufacturing process of the R535 spinning machine in the textile industry. According to the material of the centrifugal cylinder, there are mainly aluminum alloy centrifugal cylinders, carbon fiber centrifugal cylinders and glass fiber centrifugal cylinders; in 2004, due to carbon fiber microfilament The bundle price has doubled, the cost of carbon fiber centrifugal cylinder is too high, the promotion is limited, and it is basically not used in the manufacturing industry; and the use of glass fiber centrifugal cylinder in the manufacturing process to replace carbon fiber centrifugal cylinder is only four years. Due to reasons such as delamination, delamination flying cylinders and burrs, after 2010, ...
