Referring to fig. 1 to fig. 3, the present invention provides an embodiment: a transmission device for a circular knitting machine comprises a top plate 1, a first rotating shaft 2, a stroke plate 6, a second rotating shaft 9, a bottom plate 10, a screw rod 15 and a stroke block 21, wherein the bottom plate 10 is arranged below the top plate 1, supporting rods 3 distributed in a circular array are welded on the lower surface of the top plate 1, the lower ends of the supporting rods 3 are welded on the edge of the outer wall of the bottom plate 10, the first rotating shaft 2 distributed in a circular array is rotatably installed on the upper surface of the top plate 1, a wire guide wheel 4 is rotatably sleeved on the outer wall of the first rotating shaft 2, a driving motor 11 is installed on the upper surface of the bottom plate 10, the driving motor 11 adopts a Y90L2-2 type, technicians can directly purchase the circular knitting machine in the market through model searching, technical specifications can be directly looked over to know the circular knitting machine when the model equipment needs to know, therefore, the circular knitting machine does not need to be repeated description, 4 outer walls of wire wheel have cup jointed belt 5, and belt 5 cup joints at action wheel 13 outer wall, and leading wheel 7 symmetric distribution is in belt 5 both sides, and driving motor 11 drives drive shaft 12 and action wheel 13 and rotates, and then drives wire wheel 4 through belt 5 and rotates in going on.

The welding has stroke board 6 between the 1 inside of roof, and 6 surperficial symmetries of stroke board have seted up spout 8, and two inside equal activities of spout 8 are pegged graft and are had second pivot 9, and second stopper 22 is installed to the equal symmetry of two second pivot 9 lower extremes, and second stopper 22 is about 6 symmetric distribution of stroke board, and second stopper 22 can carry on spacingly to second pivot 9, ensures that leading wheel 7 and wire wheel 4 above second pivot 9 keep on the coplanar. The lower end of the second rotating shaft 9 is welded with a stroke block 21, and the upper end of the second rotating shaft 9 is sleeved with a guide wheel 7. The middle position of the lower surface of the stroke plate 6 is welded with a limiting block 14, the outer walls of the lower ends of two stroke blocks 21 are both provided with second through holes 20, the outer wall of the limiting block 14 is provided with a first through hole 18, the lower surface of the stroke plate 6 is provided with a screw rod 15, the screw rod 15 is inserted in the first through hole 18 and the second through hole 20, one end of the screw rod 15 is welded with a first stop block 19, the outer wall of the other end of the screw rod 15 is rotatably sleeved with a nut 16, when the belt 5 is used for a period of time, the belt 5 is easy to loosen, if the belt 5 is loosened, the phenomenon that the belt 5 slips easily occurs, the rotating efficiency of the driving motor 11 is reduced due to the slippage of the belt 5, the electricity consumption cost is increased, and the mechanical operating efficiency is reduced, the distance between the stroke blocks 21 is shortened by screwing the nut 16, keep belt 5 and wire guide wheel 4 and action wheel 13 surface to keep laminating, can prevent that the condition of skidding from appearing in belt 5. And after belt 5 is ageing serious, operating personnel can be with nut 16 reverse precession for the distance between leading wheel 7 increases, can make belt 5 lax more, makes to change belt 5 more light, greatly reduced the degree of difficulty and the intensity of labour of changing belt 5, the operating personnel of being convenient for more changes belt 5.

Two stroke piece 21 opposite side inner walls all are connected with spring 17, two spring 17 opposite ends all with stopper 14 both sides outer wall elastic connection, and spring 17's elasticity coefficient is the same, and when nut 16 precession, spring 17 can extrude simultaneously for leading wheel 7 relative movement's distance is the same, prevents that the condition of skew from appearing in the leading wheel 7 singly.

The working principle is as follows: after the belt 5 uses a period of time, produce lax easily, if the belt 5 produces lax, the phenomenon that the belt 5 skids appears easily, the belt 5 skids and can reduce driving motor 11's rotation efficiency, increase the power consumption cost, and can reduce mechanical operating efficiency, through precession nut 16, shorten the distance between stroke piece 21, make leading wheel 7 and belt 5 surface contact, along with leading wheel 7 gradually being close to, can make belt 5 tighten, keep belt 5 and wire wheel 4 and action wheel 13 surface to keep laminating, can prevent that the condition of skidding from appearing in belt 5. And after belt 5 is ageing serious, operating personnel can be with nut 16 reverse precession for the distance between leading wheel 7 increases, can make belt 5 lax more, makes to change belt 5 more light, greatly reduced the degree of difficulty and the intensity of labour of changing belt 5, the operating personnel of being convenient for more changes belt 5.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
