Abstract
The utility model relates to a negative pressure adjusting device for the compact spinning, comprising an adjusting valve and an air inlet pipe. The adjusting device of the adjusting valve is for controlling the negative pressure value of the deformed pipe air inlet to reduce the negative pressure difference of the air inlets down to zero, and thus the furl, collection and the floating fiber control of the extended yarn of the ingots are controlled to be in consistence through adjusting the negative pressure value of the air inlet; by using, the utility model greatly reduces the ingot difference of the finished yarn, gaining such a compact spinning with few filoplume, high strength, even sliver and high added value.
Description
Affiliated technical field
This utility model belongs to a kind of compact spinning isolated plant.
Background technology
The difference of compact spinning machine and common fine spining machine mainly is: have spinning " trigonum " in the spinning process of ring spinner, fiber in this zone has broken away from the control of front roller and drafting apron, causes a part of fiber to become uncontrolled floating fiber and forms flyings; Some fiber breaks away from control end to end and is incomplete straight configuration and forms filoplume.Simultaneously, the fiber on both sides, trigonum makes yarn strength not high with middle fiber owing to suffered tension force is different.And compact spinning machine has increased the little roller of a cover, and between front roller and little roller, the negative pressure-pumping district is housed, draw in, assemble by the yarn behind this negative pressure-pumping district counter extensioin, floating fiber is controlled, so just can alleviate the deficiency of common ring spun yarn.Negative pressure is to produce by a negative-pressure air fan, yet, longer and narrower owing to the negative pressure airduct, inlet scoop quantity is more, each inlet scoop apart from the range difference of negative-pressure air fan apart from reason such as bigger, cause each inlet scoop to produce Negative Pressure Difference, that is to say that each negative pressure-pumping district is inconsistent to the control ability of fiber, cause the yarn quality between ingot and the ingot to have very big-difference, thereby influence later process.
Summary of the invention
The purpose of this utility model addresses the above problem exactly, by adjusting to each inlet scoop negative pressure, make each negative pressure-pumping district pressure differential drop to minimum, reached unanimity substantially to gathering, gathering, the control ability of fiber in each inlet scoop, thereby further improve into the uniformity that sliver is done, increase the added value of compact spinning line products.
This utility model is achieved in that at airduct and closely spins increases a negative pressure adjusting device and transition airduct between the special pipe, negative pressure adjusting device is made up of control valve and valve shell, and control valve is installed in the valve shell, and variable partition exposes valve body.Control valve is by valve body, spherical adjusting device, sealing ring, end cap, compositions such as adjustment screw.Control the negative-pressure air-flow size of each special-shaped tube negative pressure suction district by the control valve control airduct and the transition airduct interface channel cross-sectional sizes of regulating on the negative pressure adjusting device, thereby all special-shaped tube negative pressure suction district vacuum magnitude are reached unanimity substantially.
The beneficial effects of the utility model are to regulate the inlet scoop vacuum magnitude easily according to the spinning process requirement, adopt control valve to regulate negative-pressure air-flow, and are simple and reliable.

The specific embodiment
In Fig. 1, airduct (1) forms certain vacuum under the effect of negative-pressure air fan, and airduct (1) both sides have several air entries, each air entry is by the control valve (3) in the valve shell (2), transition airduct one (4), transition airduct two (5) and closely spin special pipe (6) and be connected, and the negative pressure-pumping district is evenly distributed on the special pipe.In practical work process, because the frictional force in long and narrow air channel and each air entry are apart from the last difference of negative-pressure air fan distance, the negative pressure-pumping district blast that causes each closely to spin special pipe (6) is inconsistent, thereby causes that there is qualitative difference in institute's yarn between ingot and the ingot.In order to eliminate and to reduce this difference, we have specially designed a kind of compact spinning negative pressure adjusting device of utility model, its operation principle is as follows: under the effect of negative-pressure air fan, air-flow is from the special-shaped tube negative pressure suction district (1) of closely spinning shown in Figure 2, by aspiration channel joint (3), transition airduct two (5) shown in Figure 1, transition airduct one (4), control valve (3) and valve shell (2) enter airduct (1).In use we control the vacuum magnitude of each inlet scoop by the valve regulated screw of regulation valve body (2) top, make that Negative Pressure Difference is reduced to null value between ingot and ingot, the inconsistency of complete machine yarn qualities is reduced greatly, fundamentally improve spinning quality, improved compact spinning line products added value.Control valve (3) is simple in structure, and is easy to adjust reliable.Its structure is as shown in Figure 3: adjusting device (5) is built in the valve body (2), and end cap (3) is equipped with at two ends, and sealing ring (4) is embedded between end cap (3) and the valve body (2), and there is adjustment screw (1) on the top.During actual the use, rotatable adjustment screw (3) is controlled the position of spherical adjusting device (5), and control gas channel cross-sectional sizes realizes the control to the negative pressure-pumping district.
Claims (2)
1, closely spins a kind of negative pressure adjusting device, comprise airduct, closely spin special pipe, valve shell, negative pressure adjusting device, transition airduct etc., it is characterized in that: negative pressure adjusting device is built in the valve shell, and adjustment screw is arranged in the shell top and exposes shell.
2, a kind of compact spinning negative pressure adjusting device according to claim 1 is characterized in that: adjusting device 5
Be built in the valve body 2, end cap 3 is equipped with at two ends, and sealing ring 4 is embedded between end cap 3 and the valve body 2, and there is adjustment screw 1 on the top.
