[0030] Such as Figures 1 to 4As shown in the figure, the present invention provides a quick replacement device for a bunching wheel, which includes a fixture 1, a sleeve 2, a bunching wheel bracket 3 and an elastic reset device 4; the fixture 1 is sleeved inside the sleeve 2, the bunching wheel bracket 3 is connected to the sleeve 2, and the elastic reset device 4 is installed on the fixture 1. The function of the sleeve 2 is to fix the fixture 1, and the function of the bunching wheel bracket 3 is to fix the bunching wheel.

[0031] In a more preferred embodiment, the sleeve 2 is welded to the bunching wheel bracket 3, so that the bunching wheel is placed stably, the yarn quality is consistent, and there is no shaking.

[0032] As Figure 2 shown, in a more preferred embodiment, one end of the sleeve 2 is slotted, and the other end has a hole in the middle, and the slot communicates with the hole. The shape of the slot is "concave".

[0033] As Figure 1 shown, in a more preferred embodiment, the fixture 1 includes: a bunching wheel fixing device 11 and an elastic reset fixing device 12. One end of the bunching wheel fixing device 11 is connected to one end of the elastic reset fixing device 12; the other end of the bunching wheel fixing device 11 passes through the slot of the sleeve 2, and the other end of the elastic reset fixing device 12 passes through the hole of the sleeve 2. The end of the bunching wheel fixing device 11 passing through the slot of the sleeve 2 is used to fix the bunching wheel, and the end of the elastic reset fixing device 12 passing through the hole of the sleeve 2 is used to fix the elastic reset device 4. The elastic reset fixing device 12 is a cylinder.

[0034] As Figure 3 shown, in a more preferred embodiment, the bunching wheel fixing device 11 includes a protruding end and a fixing end. The protruding end is a cylinder 111, and the connection part between the protruding end and the fixing end is a disc 112; the fixing end is connected to the elastic reset fixing device 12. The function of the disc 112 is to cooperate with the bunching wheel so that the bunching wheel does not shake during operation. The diameter of the cylinder 111 is adapted to the inner diameter of the middle part of the bunching wheel, so that the bunching wheel can be sleeved on the cylinder 111.

[0035] As Figure 3 shown, in a more preferred embodiment, the diameter of the disc 112 is larger than the diameter of the cylinder 111. The diameter of the disc 112 is adapted to the inner diameter of the end part of the bunching wheel.

[0036] As Figure 4 shown, in a more preferred embodiment, a limiting device 5 is arranged at the end of the protruding end of the elastic reset fixing device 12, which is used to limit that the elastic reset device 4 does not break away from the elastic reset fixing device 12. The limiting device 5 can be a screw or other cylinder, and is perpendicularly arranged to the elastic reset fixing device 12.

[0037] As Figure 4As shown, in a more preferred embodiment, the elastic reset device 4 is a spring. The spring is sleeved on the protruding end of the elastic reset fixing device 12. One end of the spring is connected to the limiting device 5, and the other end is connected to the bottom end of the sleeve 2. The model of the spring is selected according to actual needs, and the rigidity of the spring should meet the force required for fixing the bunching wheel during the production process. The outer diameter of the spring is larger than the diameter of the lower hole of the sleeve 2.

[0038] During use, first sleeve the spring on the elastic reset fixing device 12, use the limiting device 5 to limit the position of its lower end, then pass the elastic reset fixing device 12 through the lower hole of the sleeve 2, and the upper end of the spring abuts against the bottom of the sleeve 2. Then pass the bunching wheel fixing device 11 through the slot of the sleeve 2, and its fixed end is connected to the part of the elastic reset fixing device 12 inside the sleeve 2. Then sleeve the bunching wheel on the protruding end of the bunching wheel fixing device 11, and press the bunching wheel tightly against the bunching wheel bracket 3.

[0039] When the bunching wheel needs to be replaced by shift every two hours, the operator presses the spring to lift the elastic reset fixing device 12 to rise inside the sleeve 2, and the bunching wheel also rises accordingly. During this process, even if the bunching wheel rotates and moves, it will not affect the quality of the yarn below. After lifting the bunching wheel away from the yarn, perform a replacement, then relax the spring, make the bunching wheel press the yarn tightly again and then resume production.

[0040] After the improvement, the operator only needs 1.5 minutes to replace the bunching wheel, saving operation time.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
