Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1-3, a yarn pressing roller device of a warping machine comprises a frame 1 and a yarn pressing roller set movably arranged on the frame 1, wherein a tension adjusting mechanism and a fixing plate 2 are further arranged on the frame 1, the tension adjusting mechanism comprises an adjusting unit and a power mechanism for driving the adjusting unit to move, the adjusting unit is arranged on the fixing plate 2, the yarn pressing roller set is connected with the adjusting unit through an automatic fine adjustment mechanism, the yarn pressing roller set comprises two parallel yarn pressing rollers 3, and two ends of each yarn pressing roller 3 are connected with the adjusting unit through the automatic fine adjustment mechanism. The winding mode of the yarn on the two yarn pressing rollers 3 is shown in figure 3, the device provides power through a power mechanism to drive the adjusting unit to adjust the distance between the two yarn pressing rollers 3, so that the two yarn pressing rollers 3 move oppositely or oppositely, the distance between the two yarn pressing rollers 3 is changed, and the tension of the yarn wound on the yarn pressing rollers 3 is further adjusted.

The power mechanism in the device is shown in fig. 1, and comprises a motor 4 fixed on a frame 1, a driving gear 5 is arranged on an output shaft of the motor 4, driven shafts 6 are arranged on the frame 1 at two sides of the motor 4, and the driven shafts 6 are fixed on the frame 1. The driven shaft 6 is provided with a first driven gear 14 and a second driven gear 15, and the first driven gear 14 and the second driven gear 15 are mounted on the driven shaft 6 through bearings. The driving gear 5 and the first driven gear 14 are connected by a chain, that is, the driving gear 5 is located between the two first driven gears 14, and then the driving gear 5, the two first driven gears 14 are connected by a chain. The second driven gear 15 is connected with the adjusting unit, so that the motor 4 is started, the driving gear 5 simultaneously drives the two first driven gears 14 to rotate, then the two second driven gears 15 are synchronously driven, and the adjusting unit is driven by the second driven gears 15 to adjust the yarn tension.

As shown in fig. 1, the adjusting unit includes adjusting mechanisms corresponding to the first driven gear 14, that is, there are two adjusting mechanisms in each adjusting unit, and as shown in fig. 2, the adjusting mechanisms include slideways 7 corresponding to the yarn pressing rollers 3, that is, there are two slideways 7 in each adjusting mechanism, the two slideways 7 correspond to the yarn pressing rollers 3 one by one, the slideways 7 are fixed on the fixing plate 2, screw rods 8 and sliding blocks 9 connected with the screw rods 8 in the slideways 7 in a threaded manner, the turning directions of the two screw rods 8 are the same, the sliding blocks 9 cannot rotate in the slideways 7, and when the screw rods 8 rotate, the sliding blocks 9 can only slide in the slideways 7 along the screw rods 8 due to rotation limitation.
