Abstract
The utility model provides a spinning holding piece, which is characterized in that the holding piece comprises a contact part and a clamping part; the contact part is in an elastic bending shape; the clamping part is bent. The utility model has the advantages that: the utility model discloses when using, the direct mount is simple to operate on the round pin stick down, and it is convenient to dismantle, changes at any time, and is with low costs, and does not influence any parts of host computer. Holding pieces are added below the lower rubber ring and above the lower pin rod, the friction force boundary of a main drafting area is increased, fibers are effectively controlled in the rapid drafting process, and cotton yarn evenness cv%, slubs, details and neps in all quality indexes of cotton yarns are improved to different degrees.
Description
Technical Field
The utility model belongs to the technical field of spinning mechanical equipment, specifically belong to a piece grips for spinning.
Background
In the spinning process, a three-roller double-leather-ring upper-lower-pin drafting device is widely adopted in the drafting part of the spinning equipment. The holding part of the main drafting zone consists of drafting components such as an upper roller, an upper rubber ring, an upper pin frame, an upper pin pressure spring, a gauge block, a lower pin rod or a lower pin frame, a lower rubber ring, a tensioner, a lower roller and the like; the double-leather-ring upper-lower-pin elastic swinging holding mechanism comprises an upper rubber ring roller and an upper pin frame, wherein the upper rubber ring is sleeved on the upper rubber ring roller and the upper pin frame, the upper rubber ring is properly tensioned by the upper pin frame, the lower rubber ring is sleeved on the lower roller, a lower pin rod and a tensioner, the lower rubber ring is properly tensioned by the tensioner, the upper pin frame is under the action of an upper pin pressure spring to press the upper rubber ring to the lower rubber ring, the fiber movement between the front holding point and the rear holding point of the upper rubber ring and the lower rubber ring in a spun yarn main drafting area is in a semi-free state, the fiber movement control force is weak, and fast fibers and slow fibers are easily disordered in the drafting process to influence the quality of cotton yarns.
In the prior art, the height of a curved surface of a common T-shaped lower pin rod is 1mm, the height of a novel curved surface of the lower pin rod is 1.5mm in the field, and the quality requirement can not be met, so that the cotton yarn evenness cv%, the details, the nubs, the neps and the broken ends are higher, the broken ends are more in the weaving process, the cloth cover style is poor, and the product price is low.
Disclosure of Invention
The utility model provides a piece grips for spinning, simple structure, the cost is low, simple to operate increases the purpose of spinning quality by a wide margin.
A spinning grip piece is characterized by comprising a contact part and a clamping part; the contact part is in an elastic bending shape; the clamping part is bent.
Further, the thickness of the holding piece is 0.5 mm; the height of the elastic bending part is 1 mm.
Further, the length of the holding piece is 19 mm.
The utility model has the advantages that:
the utility model discloses when using, the direct mount is simple to operate on the round pin stick down, and it is convenient to dismantle, changes at any time, and is with low costs, and does not influence any parts of host computer.
In the spun yarn drafting process, the tension of the rubber ring between the back holding point (two rollers and the middle and upper roller) of the upper rubber ring and the front jaw is pressure, the fiber control force is poor, holding pieces are added below the lower rubber ring and above the lower pin rod, the friction force range of a main drafting area is increased, the fiber is effectively controlled in the rapid drafting process, and the cotton yarn evenness cv%, the slub, the details and the neps in all quality indexes of the cotton yarn are improved to different degrees.

Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of another perspective structure of the present invention;
FIG. 3 is a sectional view of the present invention in use;
in the figure: 1. a contact portion; 2. a clamping part; 3. and (4) a lower pin rod.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments.
Example 1
Referring to the attached drawings, the utility model provides a spinning holding piece, which is characterized in that the spinning holding piece comprises a contact part 1 and a clamping part 2; the contact part 1 is in an elastic bending shape; after being installed, the upper surface of the lower pin rod 3 is positioned; the clamping part 2 is bent; after the fixing part 2 is installed, it is attached to the lower pin 3.
The thickness of the holding piece is 0.5 mm; the height of the elastic bending part is 1 mm; the length of the holding piece is 19 mm.
To having increased the utility model discloses after holding the piece, the cotton yarn quality experiment data of production compares with current spinning process data, forms following table:
data of the existing spinning process
The evenness is cv% | -40% km detail | -50% km detail | 35% km slub | 50% km slub | 140km nep | 200% k neps |
12.76 | 86 | 1 | 286 | 26 | 196 | 58 |
Adding grip sheet contrast data
The evenness is cv% | -40% km detail | -50% km detail | 35% km slub | 50% km slub | 140km nep | 200% k neps |
12.36 | 66 | 1 | 214 | 20 | 188 | 56 |
Note: the smaller the above value, the better the cotton yarn quality.
Claims (3)
1. A spinning grip piece is characterized by comprising a contact part and a clamping part; the contact part is in an elastic bending shape; the clamping part is bent.
2. The grip piece for spinning according to claim 1, wherein the grip piece has a thickness of 0.5 mm; the height of the elastic bending part is 1 mm.
