[0002] A texturing machine is a production equipment that can melt yarn and transform a yarn of one specification into a yarn of another specification. The texturing machine of the prior art is shown in the invention patent No. 201710793214.2 earlier applied by the applicant. However, the texturing machine has the following defects when in use:

[0003] 1. The degree of automation is relatively low, and automatic tube changing cannot be realized, which greatly reduces the production efficiency of the equipment.

[0004] 2. When manually changing the yarn tube, some yarns continue to be heated on the heating roller, and the performance of this part of the yarn will change to form waste yarn, but it will still be wound onto the new yarn tube, resulting in poor quality of the yarn bobbin.

[0005] Therefore, to solve the above technical problems, it is indeed necessary to provide an innovative tube-changing mechanism for a texturing machine to overcome the defects in the prior art.

[0019] Please refer to the instruction manual Figure 1 To Attachment Figure 4 As shown, the utility model is a tube changing mechanism of a textured yarn machine, which can automatically replace a new tube 10 after the yarn 9 is wound. The utility model is composed of a frame 1, a creel 2, a manipulator 3, a waste yarn suction tube 4, a scissors 5 and a lever assembly 6.

[0020] The creel 2 is installed on the upper part of the frame 1 and can be turned upside down. That is, when the creel 2 is turned up, it can receive a new bobbin 10 ; when the creel 2 is turned down, it can drive the bobbin 10 to rotate, thereby winding the yarn 9 onto the bobbin 10 .

[0021] The manipulator 3 is located above the creel 1, and can deliver the bobbin 10 to the creel 1, and the bobbin 10 can be clamped on the creel 1. The manipulator 3 is a manipulator 3 of the prior art, and will not be described in detail here.

[0022] The waste yarn suction tube 4, the scissors 5 and the lever assembly 6 are sequentially arranged in front of the creel 1. The waste yarn suction tube 4 can generate negative pressure, so that the yarn 9 can be continuously sucked into the waste yarn suction tube 4. In this embodiment, the waste yarn suction tube 4 is a hollow waste yarn suction tube, and a negative pressure suction nozzle 41 is provided at the end thereof, which can generate a continuous negative pressure in the waste yarn suction tube 4, thereby continuously sucking the yarn during the replacement of the new bobbin 10.

[0023] The scissors 5 can cut the yarn 9 without workers manually cutting the yarn, ensuring the subsequent automatic tube changing action. Before the yarn 9 is cut, the waste yarn suction tube 4 is located above the yarn 9. Once the yarn 9 is cut, it is immediately sucked into the waste yarn suction tube 4.

[0024] Furthermore, the waste yarn suction tube 4 can rotate to the top of the lever assembly 6 , and when rotating, the yarn 9 is driven simultaneously, so that the yarn 9 abuts against the lever assembly 6 .

[0025] The lever assembly 6 can rotate forward and backward, and can push the yarn 9 toward the creel 2. The lever assembly 6 is composed of a mounting seat 61, a driving cylinder 62, a connecting arm 63, a lever 64 and other parts. The mounting seat 61 is fixed on the frame 1. One end of the connecting arm 63 is pivotally connected to the mounting seat 61, and the other end is connected to the driving cylinder 62, and is driven to rotate by the driving cylinder 62. The driving cylinder 62 is installed on the frame 1. A turning seat 65 is provided between the connecting arms 63. The lever 64 is installed on the turning seat 65 and moves in conjunction with the turning seat 65.

[0026] When the lever assembly 6 works, the cylinder 62 is driven to push out, which drives the connecting arm 63 to rotate. When the connecting arm 63 rotates, it drives the turning seat 65 to rotate. The turning seat 65 is linked to the lever 64, and the yarn 9 is moved by the lever 64 to reach the creel 2.

[0027] The creel 2 is provided with two parallel yarn hanging pieces 21 on one side close to the lever assembly 6. Specifically, the yarn hanging piece 21 is located on one side close to the lever 64 of the lever assembly 6. A gap is formed between the two yarn hanging pieces 21.

[0028] Further, a cutter 11 is provided on the frame 1, and the cutter 11 can extend into the gap between two yarn hanging sheets 21. The lever 64 of the lever assembly 6 can be inserted between two yarn hanging sheets 21. Each yarn hanging sheet 21 is provided with an inverted hook 22, and the inverted hook 22 can hook the yarn 9. The hooked yarn 9 rotates with the rotation of the creel 2, and the yarn 9 is cut off by the inverted hook 22.

[0029] The working principle of the tube changing mechanism of the texturing machine of the present utility model is as follows: When the winding of the yarn 9 is completed, the waste yarn suction tube 4 rotates to the upper side of the yarn 9, and then the scissors 5 are activated to cut the yarn 9. The cut yarn 9 is immediately sucked into the waste yarn suction tube 4 and continuously sucked into the waste yarn suction tube 4. After the manipulator 3 installs the empty bobbin 10 on the creel 2, the creel 2 is reset. Then, the waste yarn suction tube 4 together with the yarn 9 rotates to the upper side of the lever 64, and the yarn 9 abuts against the lever 64. The lever 64 is inserted between two yarn hanging sheets 21 by the drive of the drive cylinder 62. At this time, the yarn 9 is also brought between two yarn hanging sheets 21. When the creel 2 rotates, the yarn 9 is hooked by the inverted hook 22, and when passing through the cutter 11, the yarn 9 is cut off, so that one end of the yarn can be wound onto the bobbin 10 and the other end is sucked into the waste yarn suction tube 4, thereby realizing the tube changing operation.

[0030] The above specific embodiments are only the preferred embodiments of the present creation, and are not intended to limit the present creation. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present creation shall be included within the protection scope of the present creation.
