Abstract
The utility model relates to the field of textile machinery, in particular to a needle bed movement mechanism. The mechanism comprises a needle bed, a transmission rod and a swinging arm, wherein the needle bed is connected with the transmission rod via the swinging arm; a traverse movement device is arranged on the swinging arm and comprises a servo motor, toothed belt wheel, a toothed belt and a clamp block; and a swinging device is arranged on the transmission rod and comprises an air cylinder and a connecting rod. According to the mechanism, the servo motor is adopted to drive the toothed belt wheel to rotate to drive the toothed belt to move transversely, the needle bed can be driven by the servo motor to move side to side, and the mechanism responses rapidly and displaces precisely. The air cylinder is adopted to drive the transmission rod to rotate to drive the needle bed to swing in a certain angular region, and the mechanism is reliable in performance, small in friction loss, long in service life, high in transmission speed, operates stably, and greatly improves working efficiency and beaming quality.
Description
Technical field
The utility model relates to field of textile machinery, especially a kind of needle-bar motion.
Background technology
Flower comb warping machines is in running, and needle-bar needs continually transverse shifting and swings up and down, and therefore needs one can provide the device of stable drive to realize this function, also will ensure accurate displacement simultaneously.Existing transmission device mostly adopts cam mechanism and linkage to realize production object, but, complicated structure, be unfavorable for high-speed drive, processing cost is high, and between part, impulsive force is large, serious wear, service life is short, easily causes whole transmission device to lose efficacy, and affects transmission efficiency and warp quality.
Utility model content
In order to overcome existing needle-bar transmission structures complexity, serious wear, easily lost efficacy, and affected the deficiency of transmission efficiency and warp quality, and the utility model provides a kind of needle-bar motion.
The utility model solves the technical scheme that its technical problem adopts: a kind of needle-bar motion, comprise needle-bar, drive link and swing arm, needle-bar is connected with drive link by swing arm, swing arm is provided with Traverse Displacement Unit, Traverse Displacement Unit is made up of servomotor, profile of tooth belt wheel, cog belt and clamp, drive link is provided with pendulous device, and pendulous device is made up of cylinder and connecting rod.
According to another embodiment of the present utility model, further comprise that profile of tooth belt wheel has two, one is arranged on one end of swing arm, and another is connected in the rotating shaft of servomotor, and cog belt is enclosed within on profile of tooth belt wheel, and clamp is connected to the top of cog belt.
According to another embodiment of the present utility model, further comprise that the end of needle-bar is fixed on clamp.
According to another embodiment of the present utility model, further comprise that one end of connecting rod and the piston rod of cylinder are connected, the other end is connected with drive link.
The beneficial effects of the utility model are, Traverse Displacement Unit is set in swing arm, Traverse Displacement Unit adopts the rotation of driven by servomotor profile of tooth belt wheel, drive cog belt transverse shifting, needle-bar is fixed on cog belt by clamp, and after so connecting, needle-bar just can be realized side-to-side movement under the drive of servomotor, not only be swift in response, and displacement is accurate.Pendulous device is set on drive link, and pendulous device adopts cylinder to be connected with drive link by connecting rod, and the flexible of the piston rod of cylinder can drive drive link rotation, and then drives needle-bar within the scope of certain angle, to realize the action swinging, reliable and stable.Traverse Displacement Unit and pendulous device combination are used, structural reduction, and Each performs its own functions, cooperatively interacts, stable, and frictional dissipation is little, long service life, transmission speed is fast, has greatly improved operating efficiency and warp quality.
