Abstract
The invention discloses a let-off stabilizing device of an air jet loom. The let-off stabilizing device comprises a gear, a splined shaft, friction discs, a hold-down spring and a hold-down nut. The splined shaft is connected with the gear and a bearing in an inserted manner sequentially, the bearing is fixed on a bearing seat, friction plates, the friction discs and a pressure applying disc are fixed on the splined shaft, a fixing seat is arranged outside the friction plates, the friction discs and the pressure applying disc, positioning pins are arranged on the fixing seat, the positioning pins are matched with the friction discs, the friction plates are fixed on the friction discs, the right side of the pressure applying disc is fixedly connected with one end of the hold-down spring, the other end of the hold-down spring is connected with the hold-down nut in a contact manner, the tail end of the splined shaft is a thread, and the hold-down nut is connected with the splined shaft via the thread. The let-off stabilizing device has the advantages of being simple and compact in structure, easy to operate, and capable of decreasing hidden gears and enabling let-off to be stable.
Description
Technical field
The present invention relates to a kind of loom, especially a kind of jet loom warp feeding stabilising arrangement.
Background technology
Netting machine let-off motion of the prior art, it is by warp let-off cam chair, warp let-off cam, warp let-off cam pin, warp let-off lifting arm, connecting rod, clutch is formed, warp let-off lifting arm one end is arranged on lining rotationally, other end mounting strap arbor holds, warp let-off cam is connected on the warp let-off cam chair that is sleeved on main shaft, band arbor holds and forms cam mechanism with warp let-off cam contact, the oscillating bearing that band is automatically connected in the middle part of warp let-off lifting arm and the linkage that connecting rod is formed move up and down, the other end of connecting rod be connected to be sleeved on main warp let-off roll shaft head clutch on, the pivoted arm of itself and clutch is hinged, when clutch rotates, main warp let-off roller can be driven to rotate, reach the object of the warp let-off.This mechanism easily causes instability, occurs hidden shelves phenomenon, makes loom can not the normally warp let-off, and mesh sheet, the mesh size of production differ, and anastomose is not tight.
Summary of the invention
The object of the invention is, for overcoming above-mentioned the deficiencies in the prior art, to provide a kind of jet loom warp feeding stabilising arrangement, there is advantages such as reducing hidden shelves, the warp let-off is stablized.
For achieving the above object, the present invention adopts following technical proposals:
Jet loom warp feeding stabilising arrangement, comprise gear, splined shaft, frictional disk, holddown spring and clamp nut, described gear is installed on splined shaft one end, splined shaft is fixed on bearing block by bearing, splined shaft is rotary with clamp nut, the splined shaft of bearing side is set with grooved holder, is provided with the frictional disk and dish of exerting pressure that are sleeved on successively on splined shaft in grooved holder, and the outward flange of frictional disk is fixed with friction plate, friction plate is installed on the bottom of holder by alignment pin; Exert pressure dish outside be provided with the holddown spring be enclosed within splined shaft, and the two ends of holddown spring withstand on respectively exert pressure dish and clamp nut on.
The number of described friction plate is 3 ~ 4.
The number of described frictional disk is 2.
The described diameter being arranged with the splined shaft portion of holddown spring is less than the diameter of splined shaft remainder.
The operation principle of the design is: be first connected with threaded engagement by clamp nut, be adjusted to target range, then the rotation of the coiled hair gear of loom is utilized to come driven gear and splined shaft, the rotation of splined shaft is utilized to make clamp nut to promote holddown spring, make to exert pressure to coil and inwardly apply pressure, friction operation through friction plate and frictional disk reduces hidden shelves, and the warp let-off is stablized.
The invention has the beneficial effects as follows: structure of the present invention is simple, compact, easy to operate, hidden shelves can be reduced, the warp let-off is stablized.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, 1. gear, 2. splined shaft, 3. bearing block, 4. bearing, 5. holder, 6. alignment pin, 7. friction plate, 8. frictional disk, 9. exert pressure dish, 10. holddown spring, 11. clamp nuts.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, jet loom warp feeding stabilising arrangement, comprise gear 1, spline, 2, frictional disk 8, holddown spring 10 and clamp nut 11, described gear 1 is installed on splined shaft 2 one end, splined shaft 2 is fixed on bearing block 4 by bearing 4, splined shaft 2 is rotary with clamp nut 11, the splined shaft 2 of bearing 4 side is set with grooved holder 5, be provided with in grooved holder 5 and be sleeved on frictional disk on splined shaft 28 and dish 9 of exerting pressure successively, and the outward flange of frictional disk 8 is fixed with friction plate 7, friction plate 7 is installed on the bottom of holder 5 by alignment pin 6; The exert pressure outside of dish 9 is provided with the holddown spring 10 be enclosed within splined shaft 2, and the two ends of holddown spring 10 withstand on respectively and exert pressure on dish 9 and clamp nut 11.
The number of described friction plate 7 is 3.
The number of described frictional disk 8 is 2.
The described diameter being arranged with splined shaft 2 part of holddown spring 10 is less than the diameter of splined shaft 2 remainder.
The operation principle of the design is: be first connected with threaded engagement by clamp nut 11, be adjusted to target range, then the rotation of the coiled hair gear of loom is utilized to come driven gear 1 and splined shaft 2, the rotation of splined shaft 2 is utilized to make clamp nut 11 to promote holddown spring 10, the dish 9 that makes to exert pressure inwardly applies pressure, friction operation through friction plate 7 and frictional disk 8 reduces hidden shelves, and the warp let-off is stablized.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
