Description

Flat-pushing type unwinding device of fibrilia yarn shearing machine

Technical Field

The utility model relates to a technical field of fibrilia shearing machine, concretely relates to flat pushing-type unwinding unit of fibrilia yarn shearing machine.

Background

Fibrilia refers to fibers obtained from various bast plants, including bast fibers of the cortex of annual or perennial herbaceous dicotyledonous plants and leaf fibers of monocotyledonous plants. Bast fiber crops mainly include ramie, jute, ramie, hemp, flax, kendir, kenaf and the like. Generally speaking, the fibrilia is a high-strength low-elongation type fiber, and the breaking strength of the fibrilia is 5.0-7.0 cN/dtex (2.6-4.5 for cotton fiber and 3.0-3.5 for silk). This is mainly because hemp fibers are mainly bast fibers, which are the basic skeleton of plants, have high crystallinity and orientation, and fibrils are distributed in a layered structure along the radial direction of the fibers. For example, flax has a crystallinity of 90% and an orientation of approximately 80%. Because of its high crystallinity and orientation, hemp fibers are formed into fibers having the lowest elongation at break of all fibers; in addition, the structural characteristics enable the fibrilia to obtain a large initial modulus which is 1.5-2.0 times higher than that of cotton fibers, 3 times higher than that of silk fibers and 8-10 times higher than that of wool fibers, so that the fibrilia is hard and is not easy to deform; but at the same time, the fibrilia becomes the fiber with poor elastic recovery rate, even if the deformation is only 2 percent, the elastic recovery rate is only 48 percent, and when the cotton fiber and the wool fiber are deformed in the same size, the elastic recovery rate can reach 74 percent and 99 percent.

At present, fibrilia products are more and more accepted by people, so that the market share of fibrilia is also increased year by year. In the production process of the linen fabric, the linen fiber needs to be spun into yarn, but because the linen fiber is relatively coarse, after the yarn is spun, the yarn of the linen fiber needs to be sheared by a linen fiber yarn shearing machine so as to facilitate the subsequent weaving of the linen fiber yarn. However, in the actual production process, the rotating shaft of the fibrilia yarn shearing machine rolls the sheared fibrilia yarn into a bobbin, although shearing is performed, the fibrilia itself is rough compared with other fibers, so the friction coefficient is large, which causes great labor force when the sheared fibrilia yarn bobbin is unwound, and an operator needs to additionally use a pry bar to separate the sheared fibrilia yarn bobbin from the rotating shaft, so that not only is the labor intensity high and the operation efficiency low, but also the fibrilia yarn can be damaged, and the long-term operation can also damage the equipment.

Therefore, the applicant previously filed an automatic unwinding device of a fibrilia yarn shearing machine, but in the actual use process, the swinging plate is used for unwinding a fibrilia roll in a swinging mode, so that in the unwinding process, the swinging plate presses the corresponding side of the fibrilia roll to the rotating shaft, the friction force between the fibrilia roll and the rotating shaft is increased, and the energy consumption required by the fibrilia unwinding is increased; in the actual production process, the fibrilia roll may fly out of the rotating shaft under the action of the swinging plate because the contact area between the fibrilia roll and the rotating shaft is small in the unwinding process, so that potential safety hazards are caused to operators; in severe cases, the rotating shaft is affected after a long time, and the rotating shaft is bent.
