Compact spinning special-shaped pipe lattice ring support mechanism

Abstract

The invention relates to a compact spinning special-shaped pipe lattice ring support mechanism, which comprises a support arm base and a lattice ring support arm, wherein the support arm base comprises a base fixing base; a left support arm installing plate and a right support arm installing plate are arranged on the base fixing base; a support arm rotating installing hole is formed in the supportarm installing plate; the lattice ring support arm comprises a support arm support body; support body side arms are arranged at the left side and right sides of the support arm support body; the lower end of the support body side arms are outwards provided with support arm rotating shafts; the left and right support arm rotating shafts are respectively inserted and arranged in the support arm rotating installing holes formed in the left and right support arm installing plates. The compact spinning special-shaped pipe lattice ring support mechanism is used for replacing the conventional tension mechanism; the lattice ring is loosely sleeved on a position among the special-shaped pipe, a compact roller and a support mechanism, so that accumulated patterns generated on the inner side surfaceof the lattice ring can easily go pass through high point position of the support mechanism, so that the yarn feather index and the yarn intensity can be effectively ensured.

Description

technical field [0001] The invention relates to a support mechanism for a special-shaped tube grid ring of compact spinning, which belongs to the technical field of spinning machinery. Background technique [0002] The compact spinning frame is to add a concentrating device in front of the front roller of the original spinning frame. By concentrating the fiber bundles, the purpose of reducing yarn hairiness and improving the strength of single yarn is achieved. tensioning device and other components. There is a collecting groove on one side of the collecting pipe, and a mesh ring is arranged on the upper part of the groove, and the mesh ring is driven by the transmission device to make a rotary motion to transport the drawn fiber forward. The suction port joint on the collecting pipe is connected with the suction pipe, and the negative pressure generated by the suction fan generates suction at the notch of the collecting pipe, and gathers the fibers through the mesh ring, t...

Problems solved by technology

[0003] In the existing negative pressure accumulation devices, most of the mesh rings are tensioned by spring tension mechanisms to ensure that the mesh rings are always tightly covered on the upper part of the accumulation tank. The springs used are divided into coil springs and torsion springs. The tension mechanism of this kind of spring has a relatively complicated structure, and it is easy to accumulate flowers in the spring gap, and it is very inconvenient to disassemble; and because the mesh ring is always in a tensioned state during the spinning process, the friction between the mesh ring and the tension device The resistance is large, which greatly reduces the service life; the mesh ring is in close contact with the yarn during operation, and it is easy to accumulate flying flowers and dust in the space formed by the collecting tube, mesh ring and tension mechanism, and these flying flowers and dust are not easy Cross over the tensioning high point of the tension mechanism, and it is easy to produce flower accumulation at this position. When there is a lot of flower accumulation, the rotation speed of the grid ring will be reduced, thereby affecting the yarn hairiness index and yarn strength

When there are too many accumulated flowers, the grid circle will run out of the control range of the tension support, causing the grid circle to deviate, which will cause more serious quality problems
