Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a yarn tensioning device of a warping machine which is convenient for threading yarn. Background Art

[0002] In the prior art, the yarn tensioning on the warping machine is generally carried out in the form of compression or multiple yarn guide rings are staggered. The compression form refers to applying clamping pressure to the yarn to prevent it from moving forward smoothly, thereby achieving yarn tensioning. The staggered yarn guide ring form is to use the yarn to pass through the staggered yarn guide rings in sequence, so that the yarn remains tensioned. However, in the actual use of this form of staggered yarn guide rings, when the yarn starts, it needs to pass through the yarn guide rings one by one, which will be relatively inefficient, thereby affecting the overall efficiency of the warping process. Utility Model Content

[0013] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0014] Embodiment 1:

[0015] like Figure 1-Figure 3 As shown, the utility model discloses a yarn tensioning device for a warping machine which is convenient for threading yarn, comprising a bottom plate 1, on which a row of three fixed yarn guide frames 2 are arranged in a length direction, and the spacings between adjacent fixed yarn guide frames 2 can be the same or different, and can be determined according to actual conditions. A slide rail 4 is arranged on the base at the side of the fixed yarn guide frame 2, and the slide rail 4 is perpendicular to the connecting line of the fixed yarn guide frame 2, and a movable frame 3 is slidably connected to the slide rail 4, and a movable yarn guide frame 5 is arranged at intervals on one side of the movable frame 3 close to the fixed yarn guide frame 2, and the movable yarn guide frame 5 and the fixed yarn guide frame 2 are alternately arranged in the length direction of the bottom plate 1, and when the movable frame 3 moves on the slide rail 4 to a side close to the fixed yarn guide frame 2, the fixed yarn guide frame 2 and the movable yarn guide frame 5 are in the same straight line, and a telescopic mechanism is arranged on the base, and the telescopic mechanism drives the movable frame 3 to reciprocate on the slide rail 4;

[0016] Yarn guide hooks 6 are arranged on both the fixed yarn guide frame 2 and the movable yarn guide frame 5. All the yarn guide hooks 6 have the same structure. A passage 64 for the yarn to enter is arranged on the yarn guide hooks 6.

[0017] At the beginning, the yarn needs to be passed through the yarn guide hook 6 one by one. In this solution, the telescopic mechanism can be used to drive the mobile frame 3 to move on the slide rail 4, so that the fixed yarn guide frame 2 and the movable yarn guide frame 5 are in the same straight line. At the same time, since the structure of all the yarn guide hooks 6 is the same, it is only necessary to pull the yarn to enter the interior of the wire guide hook along the channel 64 as a whole, complete the installation of all the wire guide hooks, and then use the telescopic mechanism to drive the mobile frame 3 to move, so that the fixed yarn guide frame 2 and the movable yarn guide frame 5 are misaligned, and the yarn is tensioned. This operation can improve the efficiency of passing the yarn through the wire guide hook.

[0018] The structure of the yarn guide hook 6 is as follows: it includes a U-shaped main body 61 with an opening upward, the U-shaped main body 61 is fixed on the fixed yarn guide frame 2 or the movable yarn guide frame 5, and the first extension body 62 and the second extension body 63 are respectively provided at both ends of the U-shaped main body 61. The first extension body 62 is bent and extended toward the second extension body 63, and the second extension body 63 is bent and extended toward the first extension body 62. The first extension body 62 is located above the second extension body 63, and a channel 64 for yarn to enter is formed between the first extension body 62 and the second extension body 63, and the channel 64 is connected to the interior of the U-shaped main body 61.

[0019] The upper end of the U-shaped body 61 is basically closed by the first extension body 62 and the second extension body 63, forming only an arc-shaped channel 64, so that the yarn can be quickly moved into the U-shaped body 61, improving efficiency. Moreover, the channel 64 is arranged horizontally, so during the normal tensioning process, the yarn contacts both sides of the U-shaped body 61 and is not easy to slip out of the channel 64, and the tensioning process is stable and reliable. The cross-sections of the U-shaped body 61 and the first extension body 62 and the second extension body 63 are circular, which reduces the wear on the yarn.

[0020] The structure of the telescopic mechanism is as follows: a servo motor 7 is arranged on the base, a screw rod 8 is connected to the output end of the servo motor 7, the screw rod 8 is parallel to the slide rail 4, a screw hole is arranged on the mobile frame 3 at the corresponding position of the screw rod 8, and the screw rod 8 is matched and connected with the screw hole. When the servo motor 7 drives the screw rod 8 to rotate, the mobile frame 3 matched with the screw rod 8 will move on the slide rail 4, so that the position of the mobile frame 3 can be adjusted, and the distance between the fixed yarn guide frame 2 and the movable yarn guide frame 5 in the direction of the slide rail 4 can be changed to change the tension of the yarn.

[0021] The slide rail 4 is a dovetail structure, and a dovetail groove is provided on the mobile frame 3, and the dovetail groove is slidably connected with the slide rail 4. The slide rail 4 adopts a dovetail structure, which cooperates with the mobile frame 3, and the connection is more firm, and when subjected to yarn tension, the whole is stable and reliable.
