Background

Drawing is an essential important process step in the fiber manufacturing process, often referred to as the second stage of fiber formation, or secondary formation, which is not only a necessary means of improving the physical and mechanical properties of the fiber, but also to check how well each of its previous processes has been. The drafting is generated between two drafting mechanisms, and the adhesive between the front and rear drafting mechanisms is stretched due to the difference of the surface speeds of the drafting rollers. The main function of the drawing machine is to apply external force on the adhesive in the axial direction under certain conditions, thin the single fiber in the adhesive, improve the orientation degree and change the single fiber from a low-strength and high-stretching plastic state to a high-strength and low-stretching elastic state. The conventional viscose fiber drawing roller is of a stainless steel structure, and although the material has good acid resistance, the material and manufacturing cost are high, the processing difficulty is high, the processing period is long, and a scheme is needed to solve the problem.

Detailed Description

The technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1, the embodiment provides a viscose fiber drafting roller, which comprises a roller body 12, wherein the roller body 12 comprises

A cast iron roll core 3, the cast iron roll core 3 having a draft shaft mounting hole 6 in an axial direction,

and the epoxy glass fiber reinforced plastic roller 2 is arranged on the outer surface of the cast iron roller core 3.

In this embodiment, change the integral type stainless steel roll body among the prior art into by cast iron roll core 3 and cover at its surface epoxy glass steel roller 2 and constitute, because epoxy glass steel roller 2 acid resistance is good, and only need cover at cast iron roll core 3 surface, have played outstanding corrosion resisting ability, and then protect cast iron roll core 3, and cast iron roll core 3's cost is far lower than the stainless steel roll body, consequently practiced thrift the cost for the income increases, has reduced the processing degree of difficulty simultaneously.

Further, the method also comprises the steps of,

a cast iron inner sleeve 5, wherein the center of the cast iron inner sleeve 5 is provided with a drafting shaft mounting hole 6,

a cast iron outer sleeve 7, wherein the cast iron outer sleeve 7 and the cast iron inner sleeve 5 are integrally formed and positioned outside the cast iron inner sleeve 5,
