[0022] See also Figures 1 to 4 The cam 2 has two guide rollers 4 at the bottom and two guide rollers 5 at the bottom, and the guide rollers 4 have two guide rollers 4 at the bottom.

[0023] The height adjustment mechanism includes a handwheel rod 7 inserted into the upper side wall of the concave shell 2 and rotatably connected thereto, one end of the handwheel rod 7 penetrates into the concave shell 2 and is fixedly connected to a double groove wheel 8, the inner walls of the two vertical ends of the concave shell 2 are rotatably connected to a screw rod 9 through a bearing seat, the lower ends of the two screw rods 9 are fixedly connected to a transmission wheel 10, the double groove wheels 8 are transmission-connected to the two transmission wheels 10 through a transmission belt 11, the two screw rods 9 are threadedly connected to a threaded block 12, the rear side walls of the two threaded blocks 12 are fixedly connected to a connecting rod 13, the connecting rod 13 passes through the slide 3 and is rotatably connected to the guide roller 4, when it is necessary to guide the yarn according to the yarn When the height of the two wire guide rollers 4 is adjusted by the conveying tension, the handwheel rod 7 is turned to drive the double-grooved wheel 8 to rotate. Since the double-grooved wheel 8 is connected to the two transmission wheels 10 through two transmission belts 11, the two transmission wheels 10 rotate synchronously at this time, thereby driving the two screw rods 9 to rotate synchronously. Since the two screw rods 9 are respectively threadedly connected to the two threaded blocks 12, the two threaded blocks 12 are forced to move synchronously at this time, thereby driving the two wire guide rollers 4 on the two connecting rods 13 to move synchronously, thereby realizing height adjustment, convenient adjustment, wider tension adjustment range, higher applicability, and better protection effect on yarn anti-breaking.

[0024] like Figure 2 As shown: the sliding support mechanism includes a support plate 14 fixed on the upper side wall of the base plate 1, and a slide groove 15 is opened on the side wall of the support plate 14. A slider 16 is slidably connected in the slide groove 15, and one side of the slider 16 is rotatably connected to one end of the wire guide roller 4. When the wire guide roller 4 is displaced, the slider 16 is driven to slide in the slide groove 15, which can support and stabilize the displacement of the wire guide roller 4.

[0025] like Figure 3 As shown: the elastic force adjustment mechanism includes a mounting opening 17 opened on the side wall of the fixed plate 5, a support rod 18 is fixedly connected in the mounting opening 17, a sliding sleeve 19 is sleeved on the support rod 18, a spring member 20 is fixedly connected between the sliding sleeve 19 and the inner top wall of the mounting opening 17, the spring member 20 is sleeved on the support rod 18, and the side wall of the sliding sleeve 19 is rotatably connected to the tensioning roller 6. When the yarn guide wire is transported, the yarn passes under the tensioning roller 6, and the tensioning roller 6 presses and tightens the yarn to ensure the stability of the yarn transportation. At the same time, when the tension of the yarn is changed, the pressing force on the tensioning roller 6 is increased. At this time, the sliding sleeve 19 is driven to slide and displace on the support rod 18, and the spring member 20 is squeezed by the sliding sleeve 19 to generate elastic force, which can buffer and weaken the pressure on the tensioning roller 6, thereby reducing the tension on the yarn and preventing the yarn from breaking.

[0026] like Figure 3 As shown, the inner walls on both sides of the installation opening 17 are slidably connected with the side walls on both sides of the sliding sleeve 19, so that the displacement of the sliding sleeve 19 is more stable.

[0027] like Figure 4As shown, the inner walls on both sides of the sliding opening 3 are frictionally connected with the side walls on both sides of the connecting rod 13, so that the displacement of the connecting rod 13 is more stable.

[0028] like Figure 1 As shown: the level of the tensioning roller 6 is lower than the level of the two wire guide rollers 4, which is convenient for tensioning the yarn for stable transportation.

[0029] like Figure 2 As shown: the outer side wall of the guide roller 4 is fixedly connected with a uniformly arranged limit stop ring 21 to prevent the yarn from deviating during conveyance.

[0030] Working principle: In this device, when the yarn is being transported, the yarn passes over the two guide rollers 4 and under the tension roller 6. When the yarn is being guided and transported, the tension roller 6 presses and tightens the yarn to ensure the stability of the yarn transportation. At the same time, when the tension of the yarn is changed, the pressing force on the tension roller 6 will be increased. At this time, the sliding sleeve 19 is driven to slide on the support rod 18, and the spring member 20 is squeezed by the sliding sleeve 19 to generate elastic force, which can buffer and weaken the pressure on the tension roller 6, thereby reducing the tension on the yarn and preventing the yarn from breaking.

[0031] Secondly, when it is necessary to adjust the height of the two wire guide rollers 4 according to the tension of the yarn guide conveying, turn the handwheel rod 7 to drive the double-grooved wheel 8 to rotate. Since the double-grooved wheel 8 is connected to the two transmission wheels 10 through two transmission belts 11, the two transmission wheels 10 rotate synchronously at this time, thereby driving the two screw rods 9 to rotate synchronously. Since the two screw rods 9 are respectively threadedly connected to the two threaded blocks 12, the two threaded blocks 12 are forced to move synchronously at this time, thereby driving the two wire guide rollers 4 on the two connecting rods 13 to move synchronously, thereby realizing height adjustment, convenient adjustment, wider tension adjustment range, higher applicability, and better protection effect against yarn breakage.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
