Abstract
The utility model discloses a slider device. Each end of the slider device is provided with an opening, each opening receives a pin device, and accordingly two ends of the slider device form a jaw structure and extension effect is improved.
Description
Technical field
The utility model relates to a kind of slide block device.
Background technology
Drafting system is the important component part of fine spining machine work, and its performance directly has influence on yarn quality.Improvement to the conventional spinning frame drafter also is one of the most popular research direction in the field of spinning at present.For the first break draft district, drafting multiple surpasses 1.5 times or feeding rove turn when too much, not only the turn loss increases, and because sliver is bearing larger tension force, thickness occurs sliver everywhere changes, and the turn on the sliver will reverse and move forward along hand of helix, sometimes even sliver occurs stir, just so that a large amount of turn is concentrated near the sliver that is of jaw forward, produced the heavy Distribution Phenomena of turn; For the front draft zone, owing to the reason such as unreasonable of the irregular and drafting unit design of the difference of the maturity of fiber itself, natural crimp, straightening of fibers degree and semi-products structure, cause the difference of Fiber Velocity point.Therefore, need the counter extensioin district to improve, to reach the purpose of improving the drawing-off effect.Adopting rubber ring structure counter extensioin district to improve is present the most frequently used method, has also obtained a series of result.Wherein, at Chinese patent " device that involves that is used for high-count worsted machine " (number: 96107383) with " fine spining machine four tape drawing mechanisms " (number: 012439010) disclose respectively a kind of three roller three-aprons and three rollers, four tape drawing mechanisms, the employing rubber ring structure preferably resolves the weak problem of back area draft ability of three roller form drafters, so that the total draft multiple can bring up to 100 in theory; At Chinese patent " fine spining machine four apron high draft devices " (number: disclose a kind of four apron high draft mechanisms for fine spining machine 200520073617.2), the total draft multiple is brought up to 150.Generally speaking, apron is supported by the pin assembly that is installed on the slide block, thereby forms corresponding jaw structure, produces stable friction field, and control speed change point is concentrated.Present slide block device generally only has a port, also namely only has a side mount pin device, and in actual use, often needs simultaneously mount pin device of two ends, forms simultaneously jaw structure for two ends, thereby improves the drawing-off effect.
For this, the present utility model provides a kind of slide block device that contains two ports, and two ports can be installed respectively corresponding downside pin.
Summary of the invention
The purpose of this invention is to provide a kind of slide block device that two pins can be installed simultaneously, form simultaneously jaw structure for two ends, thereby improve the drawing-off effect.
To achieve these goals, the technical scheme taked of the present utility model is:
A kind of slide block device, two ends respectively contain a port, and each port can be installed a pin assembly.
In said structure, two ports are apart from symmetry, and also namely two ports are equal to the distance of slide block center line.
In said structure, the width of port is between 2～4mm, and height is between 6～10mm, and the shape of two ends port can be determined according to selected pin assembly.
Slide block device of the present utility model can simultaneously at two ends mount pin device, form jaw structure for two ends, thereby improve the drawing-off effect simultaneously.
Description of drawings
Fig. 1 is the structural representation of slide block device of the present utility model;
Fig. 2 is the structural representation of slide block device mount pin device of the present utility model;
Wherein, 1 is slide block device, and 2,3 is port, and 4,5 is pin assembly.
The specific embodiment
As shown in Figure 1, 2, slide block device 1 contains two ports 2 and 3, and two-port 2 and 3 equates to the distances of slide block 1 center line, and two pin assemblies 4 and 5 are installed on the slide block device 1 by being embedded into two ports 2 and 3 respectively.
Claims (3)
1. slide block device, it is characterized in that: a port is respectively contained at its two ends, and each described port can be installed a pin assembly.
2. a kind of slide block device as claimed in claim 1 is characterized in that described two ports equate to the distance of slide block center line.
3. such as claim 1 or 2 described a kind of slide block devices, it is characterized in that: the width of described port is 2～4mm, highly is 6～10mm.
