DETAILED DESCRIPTION

[0024] like Figure 1 and Figure 5As shown, a yarn tension machine of the utility model includes a frame 1, a driving wheel 2 and a tension mechanism. The frame 1 is used as a supporting component of the tension machine to support and fix the remaining mechanisms; the driving wheel 2 is connected to a power source to drive the yarn to move; and the tension mechanism is used to provide tension to the yarn. Specifically, the driving wheel 2 and the tension mechanism are both arranged on the frame 1. The tension mechanism includes a supporting wheel 3 and a tension wheel 4. The supporting wheel 3 and the tension wheel 4 are both arranged on the frame 1. The tension wheel 4 is slidably connected to the frame 1. The yarn passes through the supporting wheel 3, the tension wheel 4 and the driving wheel 2 in sequence and is tensioned under the gravity of the tension wheel 4. Through the above arrangement, the yarn passing through the tension wheel 4 can be tensioned under the gravity of the tension wheel 4, the tension is constant and stable, and the tension can be adjusted according to the process requirements, and the adjustment is convenient.

[0025] like Figure 1 and Figure 2 As shown, as an implementation method, the frame 1 is provided with a slide rail 5 and a slider 6, the slider 6 is arranged on the slide rail 5 and is slidably connected with the slide rail 5, and the tension wheel 4 is arranged on the slider 6. Through the above arrangement, the sliding connection between the tension wheel 4 and the frame 1 can be achieved, so that the tension wheel 4 can apply tension to the yarn. The slide rail 5 is generally arranged vertically, and can also be appropriately tilted under special circumstances. When the tension needs to be adjusted, the slider 6 only needs to be removed from the slide rail 5.

[0026] As an implementation mode, the frame 1 is provided with an extension rod 7, and the support wheel 3 is provided on the extension rod 7. Through the provision of the extension rod 7, the yarn can be conveniently introduced and tensioned under the action of the tension wheel 4.

[0027] Specifically, the extension rod 7 is detachably connected to the frame 1. The extension rod 7 is detachable, and it is convenient to replace the extension rod 7 of different lengths, thereby facilitating the position adjustment of the extension rod 7 and facilitating the yarn feeding.

[0028] like Figure 3 As shown, as an implementation method, a plurality of guide wheels 8 are provided on the outside of the driving wheel 2. Through the above arrangement, the yarn can be guided so that the direction of the yarn can surround the outside of the driving wheel 2, thereby facilitating the driving wheel 2 to drive the yarn to move.

[0029] Specifically, the guide wheel 8 is provided with a V-shaped yarn guide groove 9. Through the above arrangement, the yarn can be more concentrated, which is convenient for the subsequent driving wheel 2 to drive the yarn to move.

[0030] like Figure 1 As shown, in this embodiment, a clamping mechanism 10 is provided on the frame 1 to make the yarn close to the driving wheel 2, and the clamping mechanism 10 includes a clamping wheel 11 and a clamping cylinder 12, and the clamping wheel 11 is connected to the piston rod of the clamping cylinder 12. By setting the clamping mechanism 10, the friction between the yarn and the driving wheel 2 can be increased to prevent the yarn from slipping on the friction wheel.

[0031] like Figure 4 As shown, as an implementation method, first protrusions 13 are provided on both sides of the driving wheel 2, and a first yarn passing groove 14 is formed between the two first protrusions 13. Through the above arrangement, it is possible to prevent the yarn from detaching from the driving wheel 2 during movement, and to prevent the yarn from being entangled on the driving wheel 2 after detachment, thereby improving the reliability of the tension machine.

[0032] As an implementation method, a second protrusion 15 is provided on both sides of the tension wheel 4, and a second yarn passing groove 16 is formed between the two second protrusions 15. Through the above arrangement, it is possible to prevent the yarn from detaching from the tension wheel 4 during movement, and to prevent the yarn from being entangled on the tension wheel 4 after detachment, thereby improving the reliability of the tension machine.

[0033] As an implementation mode, the frame 1 is provided with a driving motor 17, and the driving motor 17 is connected to the driving wheel 2 and drives the driving wheel 2 to rotate. The driving motor 17 is used as a power source to drive the driving wheel 2 to rotate.

[0034] The utility model is slidably connected to the frame 1 through the tension wheel 4, and the yarn passes through the supporting wheel 3, the tension wheel 4 and the driving wheel 2 in sequence, so that the yarn passing through the tension wheel 4 is tensioned under the action of the gravity of the tension wheel 4, the tension is constant and stable, and the tension size can be adjusted according to the process requirements. When a larger tension is needed, a heavier tension wheel 4 can be replaced, otherwise a lighter tension wheel 4 can be replaced, and the adjustment is convenient.

Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
