Problems solved by technology

[0003] At present, due to the unreasonable design of the rear pressure roller of the traditional draw frame, there are some problems, mainly reflected in that the rear pressure roller contacts the nylon seat, which is easy to wear the nylon seat, so that the distance between the rear pressure roller and the nylon becomes larger. When driving and inching, it will affect the quality of the sliver, it is easy to produce thin strips, and the CV value of the strips will increase

Abstract

The invention discloses a press roller group for a drawing frame. The press roller group comprises an active press roller and a passive press roller, wherein rotating shafts are arranged at the two ends of the active press roller and the passive press roller, a magnetic layer is covered on a roller body of the active press roller, a first elastic material layer is covered outside the magnetic layer, a metal material layer is covered on a roller body of the passive press roller, and a second elastic material layer is covered outside the metal material layer. The press roller group has the advantages that the traction and pressing work can be more effectively carried out, the quality of the subsequent wool top drawing work is improved, meanwhile, the energy source motive power for driving the press roller group is also reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of textile machinery and equipment, in particular to a pressing roller group used in a wool sliver drawing frame. Background technique [0002] The draw frame is an important textile machine, mainly used in the drawing process in the textile process. It is a spinning machine that processes several carded or combed fiber strips into fiber strips with certain quality requirements. The function of the drawing frame is to improve the internal structure of the sliver, so as to improve the uniformity of its long segments, and at the same time reduce the unevenness of the weight, make the fibers in the sliver straight and parallel, reduce the hooks, and make the fineness composite regulations, so that different types or Raw materials of different qualities are mixed evenly to achieve the specified mixing ratio. [0003] At present, due to the unreasonable design of the rear pressure roller of the traditional draw frame, the...
