The cloth winding device for warp knitting machine as shown in fig. 1 to 4 comprises a frame 100, two rotating shafts 400 rotatably arranged between the frames, wherein one rotating shaft is used as a driving shaft, and one end of the rotating shaft extends out of the frame 100 and is in driving connection with a power mechanism 200 arranged beside the frame. It should be noted that, the power mechanism generally employs a motor reducer to realize stable rotation of the rotating shaft 400. Two sets of symmetrically arranged adjusting mechanisms 300 are arranged at the upper part of the frame 100. Specifically, the adjusting mechanism includes two sets of brackets 306 respectively disposed on the frame, the two sets of brackets are symmetrically disposed, a vertically extending telescopic cylinder 303 is installed in the brackets 306, the telescopic cylinder adopts a hydraulic cylinder or an electric telescopic cylinder with higher precision, an insert block 302 is installed on the free end of the telescopic cylinder, a channel is formed on the insert block, and an axially extending adjusting rod 301 of the extending rotating shaft 400 is inserted in the channel in a sliding fit manner. A sleeve 305 is connected to the inner end of the adjusting rod 301. It should be noted that the adjusting rod is a polygonal cylinder to prevent rotation in the insert block, and the other two shaft sleeves are opposite to each other and coaxially arranged. In addition, a vertically extending guide rail 304 is provided on each sleeve 305, and a guide groove 304a extending along the length direction thereof is provided in which a roller measuring instrument 307 is provided so as to be capable of sliding up and down. A pressure lever 308 is connected between the two roller measuring devices, by means of which the rollers of the roller measuring devices are brought into contact with the guide groove.

Working principle: when the cloth is wound, a worker winds one end of the cloth on the winding shaft 500, then places the winding shaft wound with the cloth between two rotating shafts, and then drives the rotating shafts to rotate through the power mechanism, so that the winding shaft can rotate through friction force between the rotating shafts and the cloth on the winding shaft, and further uniform-speed winding is carried out on the cloth. It should be noted that, the advantage of this scheme lies in, when the windup axle rotational speed is too fast, then cloth weaving speed keep up the windup speed, and the cloth just can pull the windup axle this moment to make the windup axle overcome the frictional force between with the pivot and reduce the rotational speed, and then adapt to the weaving speed of cloth, consequently this scheme need not extra speed regulating mechanism. Meanwhile, the roller measuring instrument is arranged in the guide groove of the guide rail, the purpose of connecting the pressing rods between the two measuring instruments is that the pressing rods press the cloth surface on the winding shaft, the pressing rods rise along with the increase of the cloth roll diameter, the measuring rollers on the roller measuring instrument roll in the guide groove to measure the rising value of the pressing rods in the pressing rod rising process, the value is transmitted to the telescopic cylinders connected with the measuring rollers and drive the telescopic cylinders to retract synchronously to lift the winding shaft, the distance between the winding shaft and the two rotating shafts is always at a constant value, the pressure exerted by the two on the cloth is not increased due to the increase of the cloth roll weight, the possibility of rolling and wrinkling of the cloth roll due to the pressed cloth roll is greatly reduced, and the cloth winding quality is ensured. In addition, it should be noted that in this scheme, adjust pole and axle sleeve's setting makes the windup axle both ends limited by the axle sleeve, has avoided windup axle because rotate and at the epaxial axial float of pivot, and the edge can guarantee neat when the cloth rolling.

In addition, in order to ensure that the roller on the roller measuring instrument 307 can be in effective contact with the wall of the guide groove 304a at any time, the guide groove on the guide rail 304 is a T-shaped groove, and the portion of the roller measuring instrument located in the guide groove is adapted to the T-shaped groove, and the roller measuring instrument is slidably engaged with the T-shaped groove. In addition, for convenient to use, the depression bar is telescopic link structure, when then pulling the regulation pole, the extension or the shortening that the depression bar can adapt.

In order to make the cloth pass through the pressing bar more smoothly, a roller sleeve 309 is rotatably provided on the pressing bar 3608.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
