Abstract
The invention relates to a nipper mechanism of a combing machine, which comprises a drive device, a rocker (2), and a connecting bar (4). The rocker is driven by the drive device and fixed on a top nipper (1); one end of the top nipper (1) is articulated with a stander, and the other end is movable; one end of the connecting bar is hinged on the top nipper (1) and arranged between a contact point of the rocker (2) and the top nipper and the movable end of the top nipper (1); the other end of the connecting bar (4) is in a swing joint with a flapper valve (7); the middle of the connecting bar (4) is articulated with a pallet (5) which pushes a ratchet wheel to turn on the stander; a lower nipper (8) is fixed on the stander. The nipper mechanism increases the carding effect of the cotton bundles, is more beneficial to the related joint of the card web, and more importantly, has simple structure and reduces the transmission chain of the nipper movement, even in high speed machinery circumstances, the big noise does not appear, thus being beneficial to improve the production operating environment of workers and the health protection of workers.
Description
Technical field
The invention belongs to the cotton comber field of components, particularly relate to a kind of cotton comber nipper mechanism.
Background technology
At present, the combing machine nipper transmission device all is to adopt crank block linkage and rocker arm connecting rod mechanism two cover quadric chains to form.As shown in Figure 1, fulcrum and slide block 17 on the gear that cylinder axis is fixed are hinged, slide block 17 is enclosed within on the passive fork 16, passive fork 16 is fixed together with tongs plate axis 15, initiatively an end and the tongs plate axis 15 of fork 14 are hinged, 13 of the other end and nipper plates are point articulated, and the fulcrum and fork 11 one ends of kink on cylinder axis of nippers 12 are hinged, and another fulcrum is hinged on the initiatively stage casing of fork 14.When gear is driven by external force and when rotating, nipper swings back and forth under the effect of two cover quadric chains.The characteristics of this structure are simple in structure, are easy to make.One of its shortcoming is in carding process, and nipper plate is swung backward, and it is fixed every the square combing to realize; Two of shortcoming is the raisings along with mechanical speed, and vibration, noise that too much linkage transmission causes have become very important problem.
Summary of the invention
Technical problem to be solved by this invention provides a kind of nipper mechanism of combing machine, can not realize in the prior art deciding every the square combing defective that noise is big to solve.
A kind of nipper mechanism of combing machine, comprise drive unit, fork is driven and is fixed on the nippers by drive unit, one end of nippers is hinged on other end activity on the frame, one end of connecting rod is hinged on nippers between the movable end of fork and nippers contact and nippers, and the other end and the tongue-like pieces of described connecting rod are hinged, and the middle part of connecting rod is hinged with ratchet, ratchet promotes ratchet and rotates on frame, and nipper plate is fixed on the frame.
Described drive unit is motor-driven conjugate cam.
Described drive unit is the cam of servomotor drive.
Beneficial effect
So do not have relative motion on the frame because of nipper plate is fixed in when the present invention makes cylinder combing cotton palpus clump in use, the carding effect of cotton palpus clump is good; Drive unit drives the opening and closing of nippers; can realize the routing motion of nippers and tongue-like pieces; help the web overlap joint more; the more important thing is the driving-chain that reduces clamped plate motion system simple in structure; when realizing clamped plate motion and the optimal control that cooperates of cylinder, detaching roller; even under the high situation of mechanical speed, big noise can not occur yet, help improving workman's production operation environment, protected that the workman's is healthy.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 2, a kind of nipper mechanism of combing machine, comprise motor-driven conjugate cam 3, fork 2 is driven and is fixed on the nippers 1 by drive unit 3, and an end of nippers 1 is hinged on other end activity on the frame, and an end of connecting rod 4 is hinged on nippers 1 between the movable end of fork 2 and nippers 1 contact and nippers 1, the other end of described connecting rod 4 and tongue-like pieces 7 are hinged, the middle part of connecting rod 4 is hinged with ratchet 5, and ratchet 5 promotes ratchet 6 and rotates on frame, and nipper plate 8 is fixed on the frame.
Embodiment 2
As shown in Figure 2, a kind of nipper mechanism of combing machine, be included as the cam 3 that servomotor drives, fork 2 is driven and is fixed on the nippers 1 by drive unit 3, one end of nippers 1 is hinged on other end activity on the frame, one end of connecting rod 4 is hinged on nippers 1 between the movable end of fork 2 and nippers 1 contact and nippers 1, the other end of described connecting rod 4 and tongue-like pieces 7 are hinged, the middle part of connecting rod 4 is hinged with ratchet 5, ratchet 5 promotes ratchet 6 and rotates on frame, and nipper plate 8 is fixed on the frame.
The present invention is tongue-like pieces 7 and nippers 1 interlock in use.When nippers 1 is open, tongue-like pieces 7 is moved to detaching roller, transport the web reach, make combing web later overlap forward, this mechanism can also help the new line of cotton palpus clump simultaneously, make cotton become initiatively overlap joint by passive overlap joint by clump, help improving web overlap joint quality more.
