[0002] Artificial turf is divided into injection-molded artificial turf and woven artificial turf according to the production process. Injection-molded artificial turf adopts the injection molding process to extrude plastic particles in a mold at one time, and bends the turf using bending technology to make the grass blades arranged in an equidistant and equal amount, and the grass blades are completely uniform in height. Woven artificial turf generally uses polyethylene (PE) and polypropylene (PP) to melt, stretch and cool into straight grass yarn, and then the straight grass yarn is reeled and twisted into a cluster of yarn (grass yarn), and finally processed using tufting machines and wire breaking machines to form block-shaped artificial turf.

[0003] During the production process of lawn yarn, the yarn production equipment needs to stretch the yarn, that is, adjust its tension. This not only saves materials but also increases the production efficiency of the yarn. However, the current device for adjusting the yarn tension has a complex structure and cannot adjust the yarn tension according to the material or actual needs. Therefore, the practicability of the lawn yarn production equipment is reduced. Utility Model Content

[0026] The utility model embodiment provides a non-directional lawn yarn production device.

[0027] See also Figures 1 to 6 , including a body 1, a tension frame 3 and a thermal traction mechanism are sequentially arranged at the front end of the body 1, the tension frame 3 includes two tension rods 301 rotatably connected to each other, a limited sliding groove 303 is arranged inside the tension rod 301, and a ceramic guide ring 302 penetrating the limited sliding groove 303 and distributed in a linear array is opened on one side of the tension rod 301, a moving plate 305 is slidably connected in the limited sliding groove 303, and a fixed clamping opening 306 is opened at a corresponding position of the moving plate 305 relative to each ceramic guide ring 302, a fixed clamping plate 304 is slidably connected in the fixed clamping opening 306, and the fixed clamping plate 304 is fixedly connected to the inner wall of the limited sliding groove 303, and a moving driving component for driving the tension rod 301 to move is arranged on the body 1;

[0028] The production process of lawn yarn production equipment is: single screw main engine → cold water tank - traction roller - hot water tank - water pump - drafting roller - air deformation device - conveyor belt - tension frame 3 → hot traction roller - winding;

[0029] The bent wire is spirally wrapped around the outside of the tension frame 3 composed of two tension rods 301, and the bent wire is inserted or passed through the ceramic guide rings 302 of the two tension rods 301 in turn. After winding, it presents a conical plane. The angle between the two tension rods 301 is adjusted by using a mobile driving component, so that the tension of the bent wire can be adjusted by using the tension frame 3.

[0030] Please refer again Figure 2 , the mobile driving assembly includes a first hydraulic rod 2, two connecting rods are fixedly connected to the front end of the machine body 1, two ends of the tension rod 301 on the left side of the tension frame 3 are respectively fixedly connected to the ends of the two connecting rods, one end of the tension rod 301 on the right side of the tension frame 3 is rotatably connected to one end of the tension rod 301 on the left side, both ends of the first hydraulic rod 2 are fixedly connected to mounting rods, and the movable ends of the two mounting rods are provided with rotating slide grooves, and the inner walls on both sides of the rotating slide grooves are formed with wire grooves, and the two sliders fixedly connected to the other end of the tension rod 301 are respectively slidably connected to the two wire grooves;

[0031] The first hydraulic rod 2 drives the movable ends of the two tension rods 301 to move closer to or farther from each other, so as to adjust the angle between the two tension rods 301; the slider can slide and rotate in the wire groove.

[0032] Please refer again Figure 1 and Figure 3 The front end of the machine body 1 is fixedly connected with a second hydraulic rod 6, which is located just above the tension frame 3. The movable end of the second hydraulic rod 6 is fixedly connected with two connecting ropes 7. The movable end of the connecting rope 7 passes through the notch of the limiting slide groove 303 and is fixedly connected to one side of the moving plate 305. The outer sliding sleeve of the connecting rope 7 is provided with a spring, and the two ends of the spring are respectively fixedly connected to one side of the moving plate 305 and the inner wall of the limiting slide groove 303;

[0036] Please refer again Figure 2 The tension rod 301 is located at the holes at both ends of the ceramic guide ring 302 and is rotatably connected to a pulley 8;

[0037] The pulley 8 is used to reduce the friction between the curved wire and the inner wall of the ceramic guide ring 302, so as to avoid the curved wire rubbing against the inner wall of the ceramic guide ring 302 during the winding process, thereby preventing the curved wire from being worn on the surface.

[0038] Please refer again Figure 1 The heat traction mechanism includes heat traction rollers 5 distributed in a linear array. The heat traction rollers 5 are rotatably connected to the front end of the machine body 1. A heating rod is arranged inside the heat traction rollers 5.
