DETAILED DESCRIPTION

[0036] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0037] The present application embodiment discloses a feeding device for polyester-cotton blended yarn. Figure 1 and Figure 2 A feeding device for polyester-cotton blended yarn comprises a frame 1 fixedly arranged on a drawing frame, a guide strip platform 2 fixedly arranged on the frame 1, a connecting portion 3 slidably arranged on the guide strip platform 2, a guide cylinder 4 rotatably arranged on the connecting portion 3, and an adjusting assembly for adjusting the angle of the guide cylinder 4 on the connecting portion 3. The position of the guide cylinder 4 can be adjusted by moving the connecting portion 3, and the angle of the guide cylinder 4 can be adjusted by the adjusting assembly, so that the guide cylinder 4 can adjust the guiding angle of the cotton strips, and better adapt to the moving direction of the cotton strips, so as to meet different feeding requirements.

[0038] For details, please refer to Figure 3 and Figure 4 A slide groove 21 is provided at the bottom of the guide strip platform 2, and a slider 33 adapted to the slide groove 21 is fixedly provided on the connecting portion 3. The slider 33 is slidably connected to the slide groove 21, so that the connecting portion 3 can slide stably on the guide strip platform 2. Both ends of the guide cylinder 4 are flared to facilitate the entry and exit of the sliver, play a guiding role, and avoid damage to the sliver.

[0039] For details, please refer to Figure 3 The adjustment assembly includes a worm wheel 31 and a worm 32 that are rotatably arranged on the connecting portion 3. The worm wheel 31 and the worm 32 are meshed with each other, and one end of the worm 32 passes through the connecting portion 3 and is fixed with a knob. The guide cylinder 4 is fixed to the worm wheel 31, and the worm wheel 31 can be driven to rotate by rotating the worm 32. Therefore, when the worm wheel 31 rotates, the guide cylinder 4 can rotate accordingly, thereby adjusting the angle of the guide cylinder 4, so that the angle adjustment of the guide cylinder 4 is flexible and accurate, and can meet various feeding requirements. At the same time, the self-locking property between the worm wheel 31 and the worm 32 can ensure the stability of the guide cylinder 4, so that the guide cylinder 4 will not rotate at will.

[0040] For further information, please refer to Figure 3 and Figure 5In order to fix the position of the slider 33 on the guide bar platform 2, a pressing portion 41 is slidably provided on the slider 33, and one end of the pressing portion 41 extends from the side of the slider 33, so that the staff can press the pressing portion 41. A latching tooth 42 is fixedly provided on the pressing portion 41. The guide bar platform 2 is evenly provided with latching grooves 22 matching the latching teeth 42. The slider 33 is provided with an elastic member, which is used to push the pressing portion 41 to extend out of the slider 33, and enable the latching teeth 42 on the pressing portion 41 to be latched in the latching groove 22 on the guide bar platform 2, thereby fixing the position of the connecting portion 3.

[0041] Please refer to Figure 3 and Figure 5 The elastic member is specifically a spring 43, one end of which is fixedly connected to the pressing portion 41, and the other end of which is fixedly connected to the slider 33. The spring 43 is always in a compressed state. The pressing portion 41 is pushed by the elastic force of the spring 43, so that the latching teeth 42 are stably latched into the latching groove 22, which not only ensures the stable fixation of the slider 33, but also facilitates the release of the fixation when needed, so as to realize the flexible movement of the slider 33 on the guide bar platform 2.

[0042] Please refer to Figure 2 and Figure 4 A strip guide roller 51 is rotatably arranged on the strip guide platform 2, and the strip guide roller 51 corresponds to the strip guide platform 2 one by one, and the position of the strip guide roller 51 is higher than the strip guide platform 2, so that when the cotton strip is transported, the cotton strip is placed on the strip guide roller 51 and will not contact the strip guide platform 2. A motor 52 is fixedly arranged on the strip guide platform 2, and the motor 52 corresponds to the strip guide roller 51 one by one, and the output shaft of the motor 52 is fixedly connected to the strip guide roller 51. The motor 52 drives the strip guide roller 51 to rotate, thereby realizing automatic feeding, making the feeding process more automated and efficient, and reducing the labor intensity of the operator.

[0043] Please refer to Figure 1 and Figure 2 In order to limit the position of the sliver, a limiting sleeve 23 is sleeved on both ends of the guide strip platform 2, and a limiting rod 24 is fixedly arranged on the limiting sleeve 23, and a space for the sliver to pass through is formed between the two limiting rods 24. The position of the sliver can be limited by the limiting rod 24 to prevent it from shifting. In addition, a limiting bolt 25 is threadedly connected to the limiting sleeve 23, and by tightening the limiting bolt 25 to make it abut against the guide strip platform 2, the position of the limiting sleeve 23 on the guide strip platform 2 can be fixed, ensuring stability during use.

[0044] Please refer to Figure 1 and Figure 4A combing rod 61 is fixedly arranged on the frame 1, and combing teeth 62 are evenly distributed on the combing rod 61. A gap for a single cotton strip to pass through is formed between adjacent combing teeth 62. During the feeding process, the cotton strips are combed by the combing teeth 62, which can reduce the entanglement and confusion between the cotton strips.

[0045] Among them, the limiting rod 24, the combing rod 61 and the combing teeth 62 are all made of stainless steel with smooth surfaces, which can protect the tampon and avoid damaging the tampon.

[0046] The implementation principle of the embodiment of the present application is: by pressing the pressing part 41, the latching teeth 42 are disengaged from the latching slot 22, thereby moving the connecting part 3. After moving to the desired position, the pressing part 41 is released, and the latching teeth 42 can be engaged in the latching slot 22, thereby fixing the connecting part 3. Then, the worm 32 is rotated by turning the knob, the worm 32 drives the worm wheel 31 to rotate, and the worm wheel 31 drives the guide cylinder 4 to rotate, thereby achieving angle adjustment.

[0047] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
