Description
Technical field
The present invention relates to a kind of circular arc beating-up mechanism for weaving special fibre, unique fabric.
Background technology
Beating-up mechanism is placed between loom main shaft and reed, and mechanism is converted into the reciprocating motion of reed the gyration of main shaft, it is achieved the weft yarn entering shed open is squeezed into the action of fell.Most beating-up mechanisms are made up of four-bar linkage and slay oscillation system.The amplitude of fluctuation of reed depends on the size of wefting insertion parts and the technological requirement of unique fabric, so that it is determined that the building block of mechanism and dimensional parameters.
Shuttleless loom beating-up mechanism be structurally divided into two parts, crank and rocker mechanism and slay oscillation system.The rocking bar of fly-shuttle loom and lay sword are same parts, and rocking bar doubles as lay sword.Rocking bar drives rocker to make reciprocally swinging, and reed is flapped toward front center position with rocker, it is achieved inertial beating-up.Inertia force takes advantage of oscillating acceleration equal to the quality of swing part, in order to keep enough beating-up force, or increases the speed of loom, or increases the quality of sley system, and acceleration is big just can reduce the quality of slay oscillation system.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, it is provided that a kind of circular arc beating-up mechanism, be used for weaving special fibre, unique fabric.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of circular arc beating-up mechanism, including reed, slay and rocker, it is circular arc that the connection of described rocker has quadric chain or conjugate cam mechanism, described reed, slay and rocker, and the center of circle of circular arc is positioned at the side of described rocker center line.
Further, described double leval jib linkage is by the crank being connected on bent axle, and crank is connected with in turn hand in hand, rocking bar, and described rocking bar is connected on described rocker, and described bent axle and described rocker are hinged in frame.
Preferably, the output shaft of described double leval jib linkage is connected to described rocker end, and drives circular arc rocker.
Preferably, the output shaft of described double leval jib linkage is connected in the middle part of described rocker, and drives circular arc rocker.
Preferably, the three circular arc rockers overlapping identical 120 ° are used to form a circular beating loom.
Preferably, the four circular arc rockers overlapping identical 90 ° are used to form a circular beating loom.
Preferably, the two circular arc rockers overlapping identical 180 ° are used to form a circular beating loom.
Further, when beating, described reed gets to the surface of circular arc plank or cylindrical tube the weft yarn with warp yarns.
The invention has the beneficial effects as follows:
The parts such as reed, slay and rocker are fabricated to circular arc.The wefting insertion route of weft yarn is circular arc, and beating is that circular arc reed squeezes into fell the weft yarn with warp yarns, and the fell of common loom is straight line, and the fell of circular arc beating-up mechanism is rendered as circular arc, is used for weaving special fibre, unique fabric.
Circular arc beating-up mechanism correspondence circular arc wefting insertion, i.e. wefting insertion track is rendered as circular arc.During during loom movement, reed has been at reciprocally swinging, reed front position is exactly fell, the fell of circular arc wefting insertion track correspondence circular arc.When beating, reed gets to the surface of cylindrical plank weft yarn, and circular arc fabric can be made into a segment length, it is also possible to removes circular arc fabric in time.
For unique fabric, circular arc beating-up mechanism for loom preferably uses and is divided into crank and rocker mechanism and two systems of slay oscillation system, it is simple to arrange the variation of corresponding parts.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention, and can be practiced according to the content of specification, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.The detailed description of the invention of the present invention is shown in detail in by following example and accompanying drawing thereof.

Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the present invention is described in detail.
With reference to shown in Fig. 1, Fig. 2, a kind of circular arc beating-up mechanism, including reed 1, slay 2 and rocker D, described rocker 3 connects quadric chain or conjugate cam mechanism, described reed 1, slay 2 and rocker D are circular arc, and the center of circle of circular arc is positioned at the side of described rocker D center line.
With reference to shown in Fig. 3, described double leval jib linkage is by the crank AB being connected on bent axle A, and crank AB is connected with BC, rocking bar CD hand in hand in turn, and described rocking bar CD is connected on described rocker D, and described bent axle A and described rocker D is hinged in frame.
With reference to shown in Fig. 4, as a kind of embodiment of the present invention, the output shaft of described double leval jib linkage is connected to described rocker D end, and drives circular arc rocker.
With reference to shown in Fig. 5, Fig. 6, Fig. 7, as the another kind of embodiment of the present invention, the output shaft of described double leval jib linkage is connected in the middle part of described rocker D, and drives circular arc rocker.
With reference to shown in Fig. 8, the four circular arc rocker D overlapping identical 90 ° are used to form a circular beating loom.It is similar to, uses the three circular arc rocker D overlapping identical 120 ° to form a circular beating loom.Or, use the two circular arc rocker D overlapping identical 180 ° to form a circular beating loom.
When beating, the surface of circular arc plank or cylindrical tube got to by the weft yarn of 2, described reed and warp yarns.
Circular arc beating-up mechanism correspondence circular arc wefting insertion, weft insertion device or wefting insertion medium are passed by circular arc track with weft yarn, and wefting insertion track is rendered as circular arc.During during loom movement, reed has been at reciprocally swinging, reed front position is exactly fell, and the fell of circular arc is squeezed into weft yarn in circular arc beating.When beating, reed gets to the surface of garden cylindricality plank the weft yarn with warp yarns, and circular arc fabric can be made into a segment length, it is also possible to removes circular arc fabric in time.
Rocking bar drives rocker to make reciprocally swinging, and reed is flapped toward front center position with rocker, it is achieved inertial beating-up.Inertia force takes advantage of oscillating acceleration equal to the quality of swing part, especially needs to pay close attention to the acceleration value that front center is positioned adjacent to, and mechanism utilizes rocking bar and the negative acceleration of slay and inertia just, weft yarn is squeezed into dearly fell.
Beating is the critical process forming woven fabric, and beating-up mechanism is that inertia is big, big mechanism of consuming energy.In order to keep enough beating-up force, or increasing the speed of loom, or increase the quality of sley system, acceleration is big just can reduce the quality of slay oscillation system, the little quality being accomplished by increase slay oscillation system of the low acceleration of speed.Four bar beating-up mechanisms are bearing in frame, and mechanism kinematic produces periodically variable power and moment loading in frame.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
