Technical Field

[0001] The utility model relates to the field of textiles, in particular to a cloth pulling and adjusting device for a warp knitting machine. Background Art

[0002] Warp knitting machine is a machine for making warp knitted fabrics. It mainly uses one or several groups of parallel yarns to form loops on all the working needles of the machine fed in the warp direction to form knitted fabrics. The machine that completes this warp knitting is called a warp knitting machine. The warp knitting machine is mainly composed of a weaving mechanism, a bar slidable mechanism, a warp feeding mechanism, a pulling and winding mechanism, and a transmission mechanism. The weaving pulling adjustment of the warp knitting machine is an important link, which mainly involves how to adjust the pulling force to adapt to different process requirements.

[0003] After searching the prior art for "a traction device for textiles", the publication number is "CN214060809U". This device can easily cause deformation of the fabric if the fabric tension is not enough to ensure neat shearing of the fabric. However, in the process of the warp knitting machine pulling the fabric, the two sides of the fabric will deform and shrink inwards when the pulling roller is working, which makes it easy for the fabric to deform during the pulling process.

[0024] When implementing: Figure 1-5As shown, a fabric pulling and adjusting device for a warp knitting machine comprises: a machine housing 1, a conveying roller 2 is arranged on the inner side of the machine housing 1; an anti-deformation mechanism 3, the anti-deformation mechanism 3 is arranged on the inner side of the machine housing 1, and the surface of the anti-deformation mechanism 3 passes through the outside of the machine housing 1; wherein, the anti-deformation mechanism 3 comprises an anti-wrinkle component 31 arranged on the inner side of the machine housing 1, and an edge shifting component 32 is arranged on the surface of the anti-wrinkle component 31, and one end of the edge shifting component 32 passes through the outside of the machine housing 1.

[0025] like Figure 1-Figure 5 As shown, the anti-wrinkle component 31 includes a pulling roller 311 rotatably connected to the inner side of the machine housing 1, both ends of the pulling roller 311 extend to the outside of the machine housing 1, a bottom buckle frame 312 is clamped on the surface of the pulling roller 311, and a smoothing plate 313 is fixedly connected to the upper end inclined surface of the bottom buckle frame 312, and a positioning rod 314 is clamped on the outside of the smoothing plate 313, and both ends of the positioning rod 314 are fixedly connected to a threaded rod 316, and the other end of the threaded rod 316 extends to the outside of the machine housing 1. The anti-wrinkle component 31 also includes a first arc groove 315 opened on the side of the machine housing 1, the threaded rod 316 is located on the inner side of the first arc groove 315, and an adjusting threaded sleeve 317 is threadedly connected to the surface of the threaded rod 316, and one side of the adjusting threaded sleeve 317 contacts the surface of the machine housing 1, and both ends of the positioning rod 314 are provided with positioning rings, which are fixedly connected to the surface of the positioning rod 314. When the pulling roller 311 is rotating to pull the fabric, the operator can manually rotate the adjusting threaded sleeve 317 to adjust the position of the positioning rod 314 away from the surface of the machine housing 1 under the action of the threaded rod 316 connected with the threaded sleeve 317, so that when the positioning rod 314 is adjusted in angle, the smoothing plate 313 is driven to move accordingly, so that the smoothing plate 313 is in contact with the inclined surface below the fabric, thereby reducing the wrinkles of the fabric during the pulling process.

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the edge shifting assembly 32 includes a second arc groove 327 opened on the side of the machine housing 1 and a rotating seat 321 fixedly connected to the surface of the bottom buckle frame 312, the inner wall of the rotating seat 321 is rotatably connected with a rotating shaft 322, and the surface of the rotating shaft 322 is fixedly connected with two spiral shifters 323, and the end of the rotating shaft 322 passes through the adjacent second arc groove 327 and extends to the outside of the machine housing 1.

[0027] When the utility model is in use, the motor on one side of the machine housing 1 drives the pulling roller 311 to rotate to pull the fabric, and drives the second gear 326 to rotate through the one-way bearing 324, driving the first gear 325 meshing with it to follow the rotation, and the first gear 325 drives the rotating shaft 322 to rotate, and when the rotating shaft 322 rotates, it drives the two spiral paddles 323 to rotate synchronously, and the two spiral paddles 323 continuously pry and unfold the edge of the fabric, and the operator manually rotates the adjustment threaded sleeve 317, and moves away from the surface of the machine housing 1 under the action of the threaded rod 316 threadedly connected to it.
