Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only partial embodiments of of the present invention, rather than all embodiments.

Referring to fig. 1-3, raising tension mechanism comprises a frame (not shown in the drawing), a press roller 1 connected with the upper side of the frame, a quantitative feed roller 2 located below the press roller 1 and connected with the frame, a plurality of tension small rollers 3 located below the quantitative feed roller 2, and a plurality of tension wheels 4 connected with the frame, wherein the number of the tension small rollers 3 and the number of the tension wheels 4 are the same, the press roller 1 abuts against the quantitative feed roller 2, a gap through which yarn can pass is arranged between the press roller 1 and the quantitative feed roller 2, the lower sides of two ends of each tension small roller 3 are connected with small roller pull ropes 5, ends of the small roller pull ropes 5 far away from the tension small rollers 3 are connected with the frame, a tension pull rope 6 is connected to side of each tension small roller 3, each tension pull rope 6 bypasses the tension wheel 4 matched with the tension small roller 3 and is connected with a tension spring 7, and the .

Preferably, the number of the press rolls 1 in the present invention is two, wherein press rolls 1 are positioned directly above the metering roll 2, and press rolls 1 are positioned diagonally above the front side of the metering roll 2.

Specifically, the end of the small roller pull rope 5 far away from the small tension roller 3 and the end of the tension spring 7 far away from the tension pulley 4 are both connected with a suspender 8, the suspender 8 is connected with the frame, the side of the small tension roller 3 close to the tension pulley 4 and the bottom of the small tension roller 3 are both connected with a buckle 9, and the ends of the tension pull rope 6 and the small roller pull rope 5 far away from the frame are both connected with the buckle 9.

The working principle of the invention is as follows: the floss warp 10 enters from the press roll 1 at the upper side, bypasses the quantitative feeding roll 2, is wound out from the press roll 1 at the lower side, and then the floss warp 10 downwards bypasses the tension roller 3 and is conveyed forwards from the lower surface of the tension roller 3. In the conveying process, the small tension roller 3 is suspended, so that the small tension roller 3 can be slightly driven forwards by the stretched pile warps, the small tension roller 3 moves forwards, the small roller pull rope 5 and the tension pull rope 6 also perform corresponding reaction along with the small tension roller 3, and the tension pull rope 6 pulls the tension spring 7, but due to the interaction of forces, the pile warps are stretched, and meanwhile, the small tension roller 3 is stretched backwards by the reaction of the small roller pull rope 5 and the tension pull rope 6, so that the tension of the pile warps 10 is balanced, and the stretched pile warps cannot be too tight or too loose.
