Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spinning equipment, more particularly to a mobile air spinning yarn drum replacing device. BACKGROUND

[0002] Air spinning is a spinning method, which uses high-speed airflow to blow the fibers apart and spin into yarn, and the spun yarn is wound on the yarn drum to form finished yarn.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present application.

[0032] As shown in the accompanying drawings Figure 1 -As shown in the accompanying drawings Figure 14As shown, a mobile air-jet spinning bobbin changing device includes an air-jet spinning machine 68 and a housing 1. A bracket 69 is provided on the upper part of the air-jet spinning machine 68. The housing 1 is mounted on the bracket 69 via a moving mechanism. Two side plates 2 are mounted on the housing 1. A rotating shaft 3 is rotatably connected between the side plates 2. A driving component 11 and a driven wheel 15 are mounted on the rotating shaft 3. The driving component 11 is driven and connected to a clamping mechanism 12. A driving motor 13 is provided on the side plates 2. The driving motor 13 is driven and connected to a driving wheel 14. A transmission belt 1 connects the driving wheel 14 and the driven wheel 15. A support plate 16 is provided at the lower part of the housing 1. A displacement mechanism 17 and a displacement mechanism 20 are provided on the support plate 16. A yarn cutting mechanism 18 and a yarn suction mechanism 19 are mounted on the displacement mechanism 17. A pusher block 67 is mounted on the displacement mechanism 20.

[0033] The moving mechanism drives the housing 1 to move along the bracket 69 to the point where the yarn has been wound up. The displacement mechanism 17 drives the yarn cutting mechanism 18 and the yarn suction mechanism 19 to move to the yarn. The yarn cutting mechanism 18 cuts the yarn, and the yarn suction mechanism 19 holds the yarn end. During the yarn cutting process, the yarn suction mechanism 19 holds the yarn and provides a certain degree of fixation, allowing the yarn cutting mechanism 18 to cut the yarn more effectively. The drive motor 13 drives the drive wheel 14 to rotate. The drive wheel 14 drives the rotating shaft 3 to rotate through the transmission belt and the driven wheel 15, thereby driving the clamping mechanism 12 on the drive component 11 to rotate towards the yarn. Before the clamping mechanism 12 contacts the yarn, the fixing plate 66 moves under the drive of the displacement mechanism 20 to lift the yarn frame. Then, the push block 67 opens the yarn frame, allowing the clamping mechanism 12 to push the yarn out of the yarn frame and place the new yarn between the yarn frames. At this time, the fixing plate 66 moves under the drive of the displacement mechanism 20 to lower the bobbin frame, and the push block 67 moves away from the bobbin frame to reset the bobbin frame, which then clamps the new yarn bobbin. The driving component 11 drives the clamping mechanism 12 to move towards the driving component 11, so that the clamping mechanism 12 disengages from the yarn bobbin.

[0040] As shown in the accompanying drawings, Figure 11 The displacement mechanism two 20 comprises a lead screw motor 61, a reverser 62 and a lead screw 63. The motor shaft of the lead screw motor 61 is connected with the input end of the reverser 62, the lead screw 63 is connected with the output end of the reverser 62, the lead screw 63 is provided with a lead screw sliding block 64, the lead screw sliding block 64 is installed with a driving piece eight 65, the driving piece eight 65 is drivenly connected with a driving piece nine 21, and the driving piece nine 21 is drivenly connected with a push block 67. The lead screw motor 61 drives the lead screw 63 to rotate through the reverser 62, drives the lead screw sliding block 64 to move up and down, and adjusts the height of the push block 67.

The yarn drum is cylindrical, in order to better clamp the yarn drum, the bending radius of the pressing plate 58 at the front end of the clamping plate 56 is adapted to the diameter of the yarn drum, so that the pressing plate 58 can be attached to the yarn drum, thereby preventing the yarn drum from slipping between the bottom plate 55 and the clamping plate 56. The guide plate 57 and the guide block 59 are curved outward, which can better guide the yarn drum into the bottom plate 55 and the clamping plate 56.

[0042] The left and right ends of the front side of the fixed plate 54 are connected with limit plates 60, the limit plates 60 can abut against the back side of the yarn drum, and play a limiting role.

[0043] As attached Figure 2 -Appendix Figure 5 As shown, the moving mechanism includes two horizontal plates 4 connected between two side plates 2. Several rollers 5 are rotatably mounted on the inner horizontal plate 4, and several rollers 6 are rotatably mounted on the outer horizontal plate 4. The rollers 5 and 6 are arranged in a front-to-back configuration. A drive shaft 7 connects one set of the front-to-back rollers 5 and 6. A drive motor 9 is mounted on the side plate 2, driving a drive wheel 10. A driven wheel 8 is connected to the drive shaft 7, and a transmission belt connects the driven wheel 8 and the drive wheel 10. A guide rail 72 and a guide rail 80 are mounted on the bracket 69, with rollers 5 and 6 located within the guide rail 72 and guide rail 80, respectively. The drive motor 9 drives the drive wheel 10 to rotate, which in turn drives the driven wheel 8 to rotate via the transmission belt. The driven wheel 8 then drives the connected rollers 5 and 6 to rotate via the drive shaft 7. Roller 5 and roller 6 move within guide rail 72 and guide rail 80 respectively, thereby driving the machine box 1 to move along the bracket 69 to the yarn bobbin that needs to be replaced.

[0044] Guide rail 72 is connected to a guide plate 73 at its lower part, and a support plate 70 is connected to the side plate 2. Two guide wheels 71 are rotatably mounted on the support plate 70, and the guide plate 73 is located between the two guide wheels 71. Through the cooperation of the guide wheels 71 and the guide plate 73, the chassis 1 is guided and limited during movement to prevent it from tilting.

[0045] As attached Figure 6 As shown, a fixing frame 75 is provided on both sides of the bracket 69. Several feeding racks 74 are installed below the fixing frame 75. Each feeding rack 74 includes a U-shaped frame 76, with an extension plate 77 on both the left and right sides of the U-shaped frame 76. The extension plate 77 is positioned along the outer perimeter of the U-shaped frame 76. A feeding notch 79 is provided at the upper front position of the extension plate 77, and a feeding notch 78 is provided at the lower rear position of the extension plate 77. The feeding racks 74 are used to store yarn bobbins. Workers can pre-place multiple yarn bobbins in the feeding racks 74 for the clamping mechanism 12 to pick up and feed. The yarn bobbins are inserted through the feeding notch 79. Since the extension plate 77 is roughly U-shaped, the yarn bobbins fall at the bottom of the U-shape of the extension plate 77, with subsequent yarn bobbins falling above the first yarn bobbin. When the clamping mechanism 12 grasps the yarn bobbin, it starts from the bottommost yarn bobbin. After clamping the yarn bobbin, the clamping mechanism 12 removes it from the feeding notch 78. The remaining yarn bobbins will automatically fall down. Alternatively, the yarn bobbin can be inserted directly from the inside through the feed notch 78.

Chassis 1 operation, when the detection plate 86 is located in the part of the installation shell 82 and the human or object contact, will be along the hinge 83 inward rotation along the shaft, thus with the contact sensor 84 contact. Contact sensor 84 sends a signal to the drive motor two 9 make it stop, so that the chassis 1 stop moving. The human or object is not in contact with the detection plate 86, the detection plate 86 under the action of spring 85 back to the original position.
