Problems solved by technology

[0003] In the production process of the existing fiber, drawing it is an indispensable step. At present, in the drawing process of the fiber, it is mainly drawn by the friction force of the roller, but when drawing, in order to It is convenient for traction, since it is pulled from the bottom of the fiber yarn tube, the fiber yarn wound on the outer wall of the limit tube will be easily separated from the fiber yarn tube, but when the fiber yarn on the upper part of the fiber yarn tube is involved, due to the There is more contact with the outer wall of the fiber yarn tube, and there will be greater friction, and after the fiber yarn tube is pulled, the diameter will gradually become thinner due to the gradual pulling, and this will inevitably make the gap between the fiber yarn and the fiber yarn tube The change of the indirect contact range will also increase the friction force on the fiber filaments. Therefore, we propose a fiber filament drafting device

Embodiment 1

[0027] see Figure 1-Figure 3 , a drawing device for filaments in the figure, including a base plate 1, two support rods 2 are fixed on the base plate 1, and a support frame 3 is fixed on the support rod 2, and also includes a support frame 3 fixed on the base plate 1. The two support plates 4 on the bottom plate 1 and the connecting rods 8 fixed at the bottom of the support frame 3 are fixed with a plurality of rotating shafts 5 at equal distances on the two support plates 4, and one of the support plates 4 is outside A pressure plate 6 is rotatably installed, and a plurality of fitting shafts 7 that are adapted to the rotating shaft 5 are fixed on the pressure plate 6 at equal intervals, and the bottom end of the connecting rod 8 is fixed with a fiber filament tube by screws. An auxiliary drafting assembly 9 is mounted on the outside of the connecting rod 8 .

[0028] It should be noted that: in this scheme, when the fiber yarn is drawn, the personnel first installs the fib...

Embodiment 2

[0041] see Image 6 and Figure 7 , this embodiment further describes Example 1. In the figure, the two support plates 4 are provided with moving ports 36, and sliding rods 37 are fixed in the moving ports 36. The two sliding rods The outer side of 37 is covered with a pressing plate 39, and the outer side of the sliding rod 37 is covered with a pressing spring 38 for pushing the pressing plate 39 downward;

[0042] It should be noted that: before passing through the traction ring 28, the fiber filaments bypass the extrusion plate 39, and the designed extrusion plate 39 is subjected to the downward pressure of the extrusion spring 38, which can extract more fibers in the early stage. The filaments perform a tensioning action to avoid loosening of the filaments.

Embodiment 3

[0044] see image 3 In this embodiment, other embodiments are further described. The fitting 17 in the figure includes a support column 30 fixed on the inner side of the rotating gear ring 16, and a negative pressure cylinder 31 is slidably sleeved on the outer side of the support column 30. The outer end of the negative pressure cylinder 31 is fixed with a contact rod 32 attached to the outer wall of the fiber filament cylinder, and the end of the support column 30 located in the negative pressure cylinder 31 is fixed with a piston plate 33, and the end of the negative pressure cylinder 31 is fixed. The end is communicated with the outer side of the connecting sleeve 10 through a communication pipe. The outer side of the support column 30 is sheathed with a fitting spring 34 for pushing the negative pressure cylinder 31 to move outward.

[0045] It should be noted that when the contact rod 32 is in contact with the outer end of the fiber drum through the additional balls 35, ...

Abstract

The invention discloses a cellosilk drafting device, relates to the technical field of cellosilk drafting, solves the problem of high friction force during existing cellosilk drafting, and comprises a bottom plate, two supporting rods are fixed on the bottom plate, and a supporting frame is fixed on the supporting rods. The two supporting plates are fixed to the bottom plate, the connecting rod is fixed to the bottom of the supporting frame, a plurality of rotating shafts are fixed to the two supporting plates at equal intervals, a pressing plate is rotationally installed on the outer side of one supporting plate, a plurality of attaching shafts are fixed to the pressing plate at equal intervals, and a fiber yarn cylinder is fixed to the bottom end of the connecting rod through a screw; the auxiliary drafting assembly is additionally arranged on original drafting equipment, so that friction force generated when the fiber yarn barrel makes contact with the outer wall can be reduced when the fiber yarn barrel draws yarns, position adjustment can be conducted along with thinning of the fiber yarn barrel, guiding of fiber yarns is more flexible, and the fiber yarn barrel is not prone to falling off. And the influence caused by friction force during pulling is reduced.

Description

technical field [0001] The invention relates to the technical field of fiber filament drafting, in particular to a fiber filament drafting device. Background technique [0002] Fiber refers to a substance composed of continuous or discontinuous filaments. In plants and animals, fibers play an important role in maintaining tissue. Fibers are widely used, and can be woven into thin threads, thread ends and hemp ropes, and can also be woven into fiber layers when making paper or felt. [0003] In the production process of the existing fiber yarn, it is an indispensable step to draw it. At present, the fiber yarn is mainly drawn by the frictional force of the roller during the drawing process. It is convenient for pulling, because it is all pulled from the bottom of the fiber drum, so that the fiber wrapped around the outer wall of the limiting drum will be easily detached from the fiber drum, but when the fiber in the upper part of the fiber drum is involved, due to the Ther...
