Abstract
The invention relates to a bottom pin device of a roving frame in textile industry. The main components of the bottom pin device are arranged at the front draft area of the roving frame to replace the top pin, the iron roll, the top leather apron, the bottom pin, the bottom leather apron, the spacer and the collection of the original roving frame, thus simplifying the structure, greatly improving the yarn evenness and reducing filoplume. The airflow-type bottom device of the roving frame consists of a hollow bottom pin, a cage ring, a tensioning hook, a spring, a pipeline, a connecting piece and an air draft, wherein the hollow bottom pin can be fixed on two adjacent roller stands in the draft area of the roving frame and is provided with an air suction port and an air outlet; the cage ring is sleeved on the surface of the air suction port of the hollow bottom pin and a middle roller surface corresponding to the surface of the air suction port of the hollow bottom pin; the tensioning hook and the spring are used for tensioning the cage ring; and the pipeline and the connecting piece are used for connecting the air outlet of the hollow bottom pin and the air draft.
Description
Technical field
The present invention relates to textile machine product---the airflow-type bottom pin device of roving frame that a kind of cotton spinning and wool industry are used.
Background technology
The task of rove operation is to carry out drawing-off to larger-diameter ripe, becomes the rove than minor diameter.Larger-diameter ripe when in draw zone, moving, become flat discrete yarn, the fiber free degree at yarn edge also increases, be difficult to controlled, to such an extent as to it is discrete with fiber one end to cause fiber to scatter, the fiber that scatters has become flyings, and the discrete fiber of an end has then become filoplume, the two all makes into the uniformity deterioration that sliver is done, and makes the filoplume of resultant yarn increase.In order to strengthen control to the fiber that leaves the middle roller friction field, make it orderly speed change, enter the front roller friction field, existing technology is pin, iron roll, upper leather ring, lower pin bar, following apron, tension force hook, spacing block, a collector on main drawing area is furnished with, but the effect of these technical measures is unsatisfactory.
Summary of the invention
The objective of the invention is provides a kind of yarn of effectively controlling in main drawing area motion and improve the device of yarn form for Speed frames, the present invention except controlling fiber more effectively on the direction of motion in order the speed change, the lateral pressure to fiber that can also rely on air-flow to produce when flowing into suction hole makes fiber draw in to the center, reach the effect of fibril aggregation, greatly improved the form of yarn, improved the resultant yarn bar evenness and reduced filoplume in the draw zone motion.
Compared with prior art, the present invention has greatly improved the bar evenness of yarn, has reduced filoplume, has simplified the number of components of main drawing area, has reduced accessory consumption, has also reduced maintenance mans' labour intensity and maintenance time.
Description of drawings
Accompanying drawing is the airflow-type bottom pin device of roving frame generalized section.For giving top priority to what is the most important, air exhauster does not draw with the pipeline that is connected air exhauster and hollow downside pin 2.
In the accompanying drawing, 1---front roller 2---hollow downside pin 3---hollow downside pin exhaust outlet 4---cage ring 5---tension force hook 6---middle roller 7---medium rubber roller 8---ripe 9---hollow downside pin air entry 10---front leather roller
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Accompanying drawing is the airflow-type bottom pin device of roving frame schematic diagram, and device comprises hollow downside pin 2, cage ring 4, and tension force hook 5, pipeline that links to each other with exhaust outlet 3 and air exhauster are formed (not shown).Hollow downside pin 2 is fixed on adjacent two roller stands of draw zone, also can be fixed on the Speed frames frame, and cage ring 4 is enclosed within the position of middle roller 6 and hollow downside pin air entry 9 yarn processes, and tension force hook 5 keeps tensioning state with cage ring 4, does steady gyration.
During Speed frames work, middle roller 6 and medium rubber roller 7 are sent ripe 8 into draw zone, under the effect of front roller 1 and front leather roller 10, finish drawing-off.
During air exhauster work, air exhauster makes the air pressure in the hollow downside pin 2 reduce by pipeline, hollow downside pin air entry 9 outer air then flow into hollow downside pin 2 through air entry 9 under the pressure of atmosphere, when air flows into hollow downside pin 2, can be divided into two kinds of paths, perpendicular to hollow downside pin 2 and be parallel to hollow downside pin 2, air-flow perpendicular to hollow downside pin 2 is pressed in fiber on the cage ring 4 that can breathe freely, the air-flow that is parallel to hollow downside pin 2 is then pressed to fiber from both sides the yarn center, reduced scatter fiber and discrete fibre, thereby improved the uniformity and reduced filoplume.Cage ring 4 is under the acting in conjunction of middle roller 6 and medium rubber roller 7, and the yarn that will gather is sent into the friction field of front roller 1, and the effect of tension force hook 5 is to make cage ring 4 keep tensioning state, thereby running is more steady.
