Existing boundless yarn drums for high-twist yarns easily cause kinking during unwinding. The boundless yarn drum unwinding device comprises an unwinding device base, a yarn pressing device and a bracket, wherein the unwinding device base is cylindrical, a boundless yarn drum is sleeved on the unwinding device base, a central shaft hole is formed in the unwinding device base, the unwinding device base is mounted on a chassis in a supporting manner through a shaft mounted in the central shaft hole in a penetrating manner, the bracket is mounted on the unwinding device base and forms an inner cavity through enclosing, and the boundless yarn drum sleeved on the unwinding device base is positioned in the inner cavity; the yarn pressing device comprises an annular yarn pressing plate and a yarn pressing net, the yarn pressing net is fixedly arranged in the central hole of the yarn pressing plate, the yarn pressing net is knitted by elastic lines, a yarn passing hole is formed in the center of the yarn pressing net, the yarn pressing plate is mounted on the top of the bracket, the yarn pressing net hermetically covers the inner cavity formed by the bracket through enclosing to enable the yarn pressing net to press and lean on the end part of the boundless yarn drum in the inner cavity, and yarns of the boundless yarn drum penetrate out of the yarn passing hole. The boundless yarn drum unwinding device can effectively prevent the boundless yarn drum from causing kinking in the yarn unwinding process.
Description
Technical field
The invention belongs to frame part device field, especially relevant with a kind of boundless yarn cylinder detwisting apparatus.
Background technology
In existing yarn manufacturing technology, boundless one-tenth cylinder progressively substitutes and has limit to become cylinder, boundless one-tenth cylinder package amount is large, the time of doffing is longer, reduced the more number of times of change of bobbins, reduced operative employee's labour intensity, yet existing boundless one-tenth cylinder is only suitable for doing the low twist product, during high twist due to yarn without edge, while causing yarn, often kink together, can't be smooth and easy, affect the use of yarn in follow-up use.
Summary of the invention
Purpose of the present invention is intended to overcome the existing boundless yarn cylinder of high twist yarn and moves back the defect that while separating, yarn easily kinks, and a kind of boundless yarn cylinder detwisting apparatus that can adapt to the yarn of high twist yarn is provided.
For this reason, the present invention is by the following technical solutions: boundless yarn cylinder detwisting apparatus, comprise the detwisting apparatus base, it is characterized in that, described detwisting apparatus also comprises wire pressing device and support, described detwisting apparatus base is cylindrical shape, boundless yarn cylinder can be set on the detwisting apparatus base, the detwisting apparatus base is provided with central shaft hole, the detwisting apparatus base supports and is installed on frame by the axle that is threaded onto its central shaft hole, support is installed on the detwisting apparatus base and surrounds an inner chamber, and the boundless yarn cylinder that makes to be set on the detwisting apparatus base is arranged in this inner chamber, wire pressing device comprises annular pressing line disk and line ball net, the line ball net is fixed in the pressing line disk centre bore, the line ball net is weaved into by elastica, center is provided with cable-through hole, pressing line disk is installed on described top of the trellis, the inner chamber that line ball net capping support surrounds, make the line ball net be pressed against the boundless yarn cylinder end in inner chamber, in inner chamber, the yarn of boundless yarn cylinder passes from the cable-through hole of line ball net, in the yarn unwinding process, the movement of yarn is subject to pressing of line ball net all the time, also along cable-through hole, circumferentially constantly conversion is tactile by point for yarn, yarn has certain tension force, can not kink, after Yarn break, yarn and thread head is always being pressed by the line ball net, can not retract and kink together.
As to technique scheme supplement and perfect, the present invention also comprises following technical characterictic.
Described pressing line disk comprises mutually recline fixing chassis and shrouding disc, and described line ball network edge is fixed between chassis and shrouding disc.
Described line ball net is weaved into annular by many elasticas, centre bore is cable-through hole, every elastica bends to arc, the elastica two ends are positioned at the annular outboard edge, and the elastica arc apex is positioned at annular inboard and distributes circumferentially, and adjacent two arc apex are spaced a distance, after intersecting, two adjacent elasticas form the concave point at annular inboard edge, yarn is drawn from these concave points, after Yarn break, yarn and thread head is had to the effect of card pressure, makes yarn and thread head be not easy to retract to produce and kinks.
Described support is four L-type pipes, one end of pipe is fixed on the detwisting apparatus base, and the other end, through being located at the through hole on pressing line disk, supports fixedly wire pressing device, make wire pressing device can adjust the spacing with respect to the detwisting apparatus base, adapt to the boundless yarn cylinder of different length.
Use the present invention can reach following beneficial effect: the present invention sets up wire pressing device on detwisting apparatus, when the high twist yarn, loose thread can be stablized between reticulated elastomeric line and boundless yarn cylinder end face, make yarn remain certain tension force, can effectively prevent from kinking in boundless yarn cylinder yarn unwinding process.
