Description

Technical Field

[0001] This utility model relates to the field of twisting machine parts, and in particular to an integrated inner yarn tensioner and twister device. Background Technology

[0002] The existing inner yarn tensioner assembly and twister assembly are two separate parts. The inner yarn tensioner assembly is mounted on the spindle can, while the twister assembly is mounted on the support arm. When changing the yarn, the inner yarn below the twister must be cut, the support arm rotated to move the twister assembly away from the center of the spindle can, then the inner yarn inside the spindle can is cut, and the spindle can and inner yarn tensioner assembly are removed together. The inner yarn is then replaced and reconnected. This structure makes the operation steps complex. In addition, the gap between the twister assembly and the inner yarn tensioner assembly is too large, which can easily cause the outer and inner yarns to become tangled under the twister during the start-up or shutdown of the twisting machine.

[0031] like Figure 2 As shown, an integrated inner yarn tensioner and twister device includes a tension frame 114, which is fixedly mounted on a swingable swing arm 500; preferably, the swing mode of the swing arm 500 is a roughly horizontal swing.

[0032] A tensioner is provided near the bottom of the tension frame 114, and a twister is provided near the top of the tension frame 114.

[0033] Preferred solutions include Figure 3 , 4 In the process, the structure of the twister is as follows: the twisting frame 112 is rotatably supported on the tension frame 114 along the vertical axis, the twisting plate 108 is provided at the bottom of the twisting frame 112, the outer yarn ceramic eye 109 is provided near the edge of the twisting plate 108, and the inner yarn ceramic tube 110 is provided near the middle of the twisting plate 108.

[0034] The twisting frame 112 has a hollow structure, with a twisting wheel 111 on it and a vertical yarn guide tube 115 on the top of it.

[0035] Preferred solutions include Figure 3 , 4 In this configuration, the axis of the twisting wheel 111 is horizontally arranged, and there are 1 to 2 twisting wheels 111.

[0036] like Figure 3 In the middle, when there is only one twisting wheel 111, the twisting wheel 111 is located in the middle of the twisting frame 112;

[0037] like Figure 4 In this configuration, when there are two twisting wheels 111, they are arranged symmetrically side by side. This structure is designed to accommodate the twisting of different yarn types.

[0038] Preferred solutions include Figure 3 , 4 In the middle, the twisting frame 112 is connected to the tension frame 114 near the top via the upper bearing assembly 119, and the twisting frame 112 is connected to the tension frame 114 near the bottom via the lower bearing assembly 118.

[0039] Preferred solutions include Figure 2 In the middle, the edge of the twisting disc 108 is provided with a protective disc 106, and the edge of the protective disc 106 has a rounded structure. This structure prevents the outer yarn 400 from contacting the protective disc 106 and causing wear.

[0040] Preferred solutions include Figure 2 In the middle, the tensioner is located below the twisting disc 108, and the structure of the tensioner is as follows:

[0041] The inner yarn tension wheel assembly 103 and the driven wheel assembly 104 are connected to the tension frame 114. The inner yarn tension wheel assembly 103 is provided with a damping structure to provide resistance to the rotation of the inner yarn tension wheel.

[0046] The damping structure includes a friction disc damping structure, a permanent magnet damping structure, or an electromagnetic damping structure.

[0047] The friction disc damping structure consists of two disc-shaped structures that are in contact with each other, one of which is fixed and the other rotates with the inner yarn tension wheel, generating damping between the two friction discs.

[0048] The permanent magnet damping structure comprises two disc-shaped structures, each with a pair of magnets facing each other, including a set of magnets that attract each other. These magnets are respectively positioned on a fixed disc and a rotating disc that moves with the inner yarn tension wheel. Damping is generated between the two discs by magnetic force. The electromagnetic damping structure is similar to the permanent magnet damping structure, except that the permanent magnets are replaced with electromagnets.

[0049] Preferred solutions include Figure 2 In the middle, the top of the tension frame 114 is fixedly connected to the horizontally swinging support arm 500, and one extreme position of the swing support arm 500 makes the axis of the twisting frame 112 of the tension frame 114 coincide with the axis of the spindle tank 200.

[0050] Another extreme position of the swing arm 500 causes the tension frame 114 to move away from the top of the ingot container 200 so that the ingot container 200 can be opened;

[0051] A magnet positioning seat 600 is fixed on the tension frame 114. Multiple first magnets 601 are provided on the magnet positioning seat 600. Multiple second magnets 602 are provided on the bearing seat below the twisting disc 108. The first magnets 601 and the second magnets 602 form a pair of magnets to restrict the rotation of the bearing seat below the twisting disc 108. The gap between the first magnets 601 and the second magnets 602 allows the outer yarn 400 to pass through.

[0052] In this example,

[0055] A tensioner is provided near the bottom of the tension frame 114, and a twister is provided near the top of the tension frame 114.

[0056] Preferred solutions include Figure 3 , 4 In the process, the structure of the twister is as follows: the twisting frame 112 is rotatably supported on the tension frame 114 along the vertical axis, the twisting plate 108 is provided at the bottom of the twisting frame 112, the outer yarn ceramic eye 109 is provided near the edge of the twisting plate 108, and the inner yarn ceramic tube 110 is provided near the middle of the twisting plate 108.

[0063] Preferred solutions include Figure 1 In the middle, the tensioner is located below the twisting disc 108, and the structure of the tensioner is as follows:

[0064] The inner yarn tension wheel assembly 103 and the driven wheel assembly 104 are connected to the tension frame 114. The inner yarn tension wheel assembly 103 is provided with a damping structure to provide resistance to the rotation of the inner yarn tension wheel.

[0070] Example 3:

[0071] Based on Embodiment 1 or 2, when the present invention operates, as follows: Figure 2In the middle, the inner yarn 300 enters from the lower inner yarn ceramic tube 116, passes through the yarn clamping disc assembly 102, and after winding 4 to 7 times on the driven wheel assembly 104 and the inner yarn tension wheel assembly 103, it is led out from the driven wheel assembly 104, passes through the guide wheel assembly 105, and then enters from the inner yarn ceramic tube 110. It is introduced into the twisting frame 112, and after being wound once on the twisting wheel 111, it is twisted with the outer yarn 400 to become the twisted yarn 700.

[0072] After the outer yarn 400 is thrown out from the twisting disc in the spindle assembly, it passes through the outer yarn ceramic eye 109 of the twisting disc 108, driving the entire twister to rotate at high speed. Then, the outer yarn 400 is wound once on the twisting wheel 111 and twisted with the inner yarn 300 to become a twisted yarn 700, which then passes through the yarn guide tube 115. After the yarn processing is completed, the inner yarn 300 is cut, and the swing arm 500 is swung to remove the integrated inner yarn tensioner and twister device from the top of the spindle tank 200, thus realizing the replacement of the inner yarn 300; or the integrated inner yarn tensioner, twister device and spindle tank 200 can be disassembled as a whole to realize the replacement of the inner yarn 300.
