Abstract
A balanced connecting rod beating-up device for a shuttleless loom comprises a main shaft, a rocking shaft, a sley seat foot arranged on the rocking shaft and a sley seat arranged on the sley seat foot, wherein the rocking shaft is fixedly connected with a rocking rod, the main shaft is in transmission connection with the rocking rod through a crank connecting rod mechanism, an included angle alpha is formed between the central line of the rocking rod and the central line of the sley seat foot, and the value of the included angle alpha is larger than 90 degrees and smaller than or equal to 180 degrees. The sley foot, the sley, the rocking shaft, the connecting rod and the crank-connecting rod mechanism form a whole body which can swing back and forth around the axial lead of the rocking shaft, and the gravity center of the whole body is close to the axial lead of the rocking shaft, so that the inertia of the whole body is convenient to reduce, and the vibration of the beating-up device can be reduced.
Description
Technical field
The present invention relates to the beating device of a kind of beating device of loom, particularly a kind of shuttleless loom.
Background technology
In the prior art, the beating device of loom be arranged at the main shaft of loom and the reed that beats up between, it comprises the rocker that rotated by main shaft drives, be arranged at lay sword on the rocker, be arranged at the slay on the lay sword, reed promptly is installed on the slay, beating device is converted to the reciprocally swinging of reed with the gyration of main shaft, thereby the weft yarn that will enter the shed open of loom is squeezed into the fell of loom.But because the slay swing mechanism in the beating device has been concentrated the most quality in the beating device, and the technological requirement of beating up reed and slay are longer apart from the axial line of rocker, this makes the slay swing mechanism have very big inertia, so at the slay swing mechanism during around the axial line reciprocally swinging of rocker, the inertial load of slay swing mechanism can make this beating device that the frame of loom is produced bigger inertia impact, make the reed violent oscillatory motion, cause beating up that quality is low, the weft yarn in the fabric and warp thread be not in conjunction with firm.
Summary of the invention
The object of the invention provides a kind of balance type bar-connected beat up unit for shuttle-free weaving machine, and it can reduce the overall inertia around each parts of the axial line reciprocally swinging of rocker.
Technical scheme of the present invention is: a kind of balance type bar-connected beat up unit for shuttle-free weaving machine, the rocker that comprises main shaft, back and forth rotates, be arranged at lay sword on the described rocker, be arranged at the slay on the described lay sword by described main shaft drives, be fixedly connected with rocking bar on the described rocker, described main shaft is in transmission connection with rocking bar mutually by toggle, have angle α between the center line of described rocking bar and the center line of lay sword, the value of this angle α is less than or equal to 180 degree greater than 90 degree.
Described toggle comprises the crank that is fixedly connected with described main shaft, the connecting rod that is connected with described crank phase pivot, and described connecting rod departs from axial line one segment distance of rocker, and described connecting rod is connected with the rocking bar phase pivot.
The present invention compared with prior art, has following advantage: toggle and rocking bar are set between main shaft and rocker, have angle between the center line of rocking bar and the center line of lay sword, make lay sword, slay, rocker, connecting rod and toggle are formed the integral body around the axial line reciprocally swinging of rocker, this whole center of gravity is near the axial line of rocker, thereby be convenient to reduce this whole inertia, can reduce the vibration of beating device, thereby reduce impact to frame, and can improve the rigidity and the quality of beating up, make the fabric of producing plentiful stiffening.
Description of drawings
Accompanying drawing 1 is a stereogram of the present invention;
Accompanying drawing 2 is a main cross-sectional schematic of the present invention;
Wherein: 1, main shaft; 2, crank; 3, connecting rod; 4, rocking bar; 5, rocker; 6, lay sword; 7, slay; 8, reed; 9, toggle; 10, rocker supporting base.
The specific embodiment
Referring to accompanying drawing 1-accompanying drawing 2, a kind of balance type bar-connected beat up unit for shuttle-free weaving machine, comprise main shaft 1, drive and the rocker 5 that back and forth rotates, be arranged at lay sword 6 on the described rocker 5, be arranged at the slay 7 on the described lay sword 6 by described main shaft 1, be fixedly connected with rocking bar 4 on the described rocker 5, described main shaft 1 is in transmission connection with rocking bar 4 mutually by toggle 9, have angle α between the center line of the center line of described rocking bar 4 and lay sword 6, the value of this angle α is less than or equal to 180 degree greater than 90 degree.
Described toggle 9 comprises the crank 2 that is fixedly connected with described main shaft 1, the connecting rod 3 that is connected with described crank 2 phase pivots, and described connecting rod 3 departs from axial line one segment distance of rocker 5, and described connecting rod 3 is connected with rocking bar 4 phase pivots.
Main shaft 1 is arranged on the frame of loom and by motor-driven and rotates, rocker 5 is arranged on the rocker supporting base 10 rotationally, shown in accompanying drawing 2, when doing gyration, main shaft 1 drives crank 2 and connecting rod 3 reciprocally swingings, driving rocker 5 by connecting rod 3 back and forth rotates on rocker supporting base 10, lay sword 6 is reciprocally swinging under the drive of rocker 5, slay 7 is promptly made reciprocally swinging under the drive of lay sword 6, reed 8 is installed on slay 7, during slay 7 swing, reed 8 is about to introduce the weft yarn of the shed open of loom and squeezes into fell.In the beating device motion process, the angular acceleration of each rod member causes the cyclically-varying of inertia force and moment, so must consider the inertia force and the mutual balance of moment when cyclically-varying of each rod member in this beating device, vibration for the frame that reduces loom, need the position of arranging the relative rocker supporting base 10 of its centroid position, with the inertia force that reaches each rod member in crank 2 each revolutions and the optimal balance of moment of inertia effect according to the quality of each rod member.The present invention is divided into two rigid members with rocking bar 4 and lay sword 6, and these two rigid members are connected firmly on the rocker 5 by fixing angle α and form an integral body, this integral body is made reciprocally swinging on rocker supporting base 10, the value of angle α then designs according to the quality and the centroid position of rocking bar 4 with lay sword 6 and toggle 9, the dynamic equilibrium that the method for this separation rocking bar 4 and lay sword 6 helps keeping this beating device, make the rigidity of beating up of reed 8 strengthen, be convenient to make weft yarn in the fabric straight and be combined in the warp thread firmly, thereby can improve the plentiful stiffness of fabric, simultaneously, rocking bar 4 separates with lay sword 6 and angled setting, can make the compact conformation of this beating device, be convenient to reduce its packaging volume.
