[0021] Example 1

[0022] In the prior art, the surface of the yarn guided out from the yarn storage drum may be adhered to debris, thread ends, miscellaneous threads and other attachments. If these attachments are not removed, they will still adhere to the yarn after twisting, seriously affecting the quality of the twisted yarn.

[0023] Based on this, the utility model provides a twisting device for a twisting machine, such as Figure 2 and Figure 4 As shown, it includes a cleaning mechanism and a twisting machine 100 (existing technology, the specific working principle is not repeated here); Figure 1-4 As shown, the cleaning mechanism includes a support frame 110, a placement block 120 disposed in the support frame 110, and a plurality of cleaning chambers 130 disposed in the placement block 120. The inner wall of the cleaning chamber 130 is provided with a plurality of bristles 140, and the interior of the plurality of bristles 140 forms a conical chamber. Figure 1-2 As shown, each cleaning chamber 130 is detachably provided with a cleaning cylinder 150, and the bristles 140 are arranged on the inner wall of the cleaning cylinder 150. Figure 1-4 As shown, the twisting device further comprises a frame 200 disposed at the feeding end of the cleaning cylinder 150, and a plurality of yarn storage cylinders 210 are rotatably disposed in the frame 200; the number of the yarn storage cylinders 210 is the same as the number of the cleaning cylinders 150. Further, as Figure 1-2 As shown, the axial direction of the cleaning cylinder 150 is vertical, the yarn storage cylinder 210 is arranged at the bottom end of the cleaning cylinder 150, and the support frame 110 is provided with a guide roller 220, and the guide roller 220 is arranged at the top of the plurality of cleaning cylinders 150; Figure 2 As shown, the cleaning mechanism and the frame 200 are arranged vertically, and the cleaning mechanism and the twisting machine 100 are arranged horizontally. Further, the feeding end of the cleaning chamber 130 is detachably provided with a chamber cover 180 (threaded or embedded in other ways), and the inner wall of the discharging end of the cleaning chamber 130 is provided with a retaining ring 230; the center of the chamber cover 180 is provided with a wire inlet hole 190; one end of the cleaning cylinder 150 contacts the retaining ring 230, and the other end contacts the chamber cover 180.

[0024] Working principle: Figure 1-2As shown, the yarns in the plurality of yarn storage cylinders 210 are introduced into the cleaning cylinder 150 along the bottom of the cleaning cylinder 150 directly above the yarn storage cylinders 210, and then pulled out along the top of the cleaning cylinder 150 in sequence, and introduced into the twisting machine 100 together. After the yarn is introduced into the cleaning cylinder 150, the attachments such as broken hair, thread ends, and miscellaneous threads adhering to the surface of the yarn are cleaned by the bristles 140, and continue to remain in the bristles 140 or the conical cavity, so as to achieve the purpose of graded cleaning, and at the same time, the attachments can be distributed in a larger area in the cleaning cylinder 150, so that the attachments can be effectively avoided from accumulating in the same place, resulting in an increase in the frequency of replacement or cleaning of the bristles 140, and reducing the twisting efficiency. In addition, in the utility model, by adding the cleaning cylinder 150, when too many attachments are adhered to the bristles 140, the cleaning cylinder 150 can be taken out of the cleaning cavity 130, thereby improving the operational flexibility.

[0025] Furthermore, by adding the guide roller 220, the present embodiment can avoid the friction between the yarn and the top wall of the cleaning cylinder 150, thereby reducing the degree of yarn wear.

[0026] Example 2

[0027] A twisting device for a twisting machine, such as Figure 2 and Figure 4 As shown, it includes a cleaning mechanism and a twisting machine 100 (existing technology, the specific working principle is not repeated here); Figure 1-4 As shown, the cleaning mechanism includes a support frame 110, a placement block 120 disposed in the support frame 110, and a plurality of cleaning chambers 130 disposed in the placement block 120. The inner wall of the cleaning chamber 130 is provided with a plurality of bristles 140, and the interior of the plurality of bristles 140 forms a conical chamber. Figure 1-2 As shown, each cleaning chamber 130 is detachably provided with a cleaning cylinder 150, and the bristles 140 are arranged on the inner wall of the cleaning cylinder 150. Figure 1-4 As shown, the twisting device further comprises a frame 200 disposed at the feeding end of the cleaning cylinder 150, and a plurality of yarn storage cylinders 210 are rotatably disposed in the frame 200; the number of the yarn storage cylinders 210 is the same as the number of the cleaning cylinders 150. Further, as Figure 3 and 4 As shown, the axial direction of the cleaning cylinder 150 is horizontal. Figure 4 As shown, the frame 200, the cleaning mechanism and the twisting machine 100 are distributed on the left and right.

[0028] Working principle: Figure 3As shown, the yarns in the plurality of yarn storage drums 210 are introduced into the cleaning drum 150 along the left end of the cleaning drum 150 on the right side thereof, and then pulled out along the right end of the cleaning drum 150 in sequence, and introduced into the twisting machine 100 together. After the yarns are introduced into the cleaning drum 150, the broken hair, thread ends, miscellaneous threads and other attachments adhering to the surface of the yarns are cleaned by the bristles 140, and continuously remain in the bristles 140 or the conical cavity, so as to achieve the purpose of graded cleaning, and at the same time, the attachments can be distributed in a larger area in the cleaning drum 150, so that the attachments can be effectively prevented from accumulating in the same place, resulting in an increase in the frequency of replacement or cleaning of the bristles 140, and reducing the twisting efficiency.

[0029] Further, on the basis of Example 2, the feed end of the cleaning chamber 130 is detachably provided with a chamber cover 180 (threaded or embedded), and the inner wall of the discharge end of the cleaning chamber 130 is provided with a retaining ring 230; the center of the chamber cover 180 is provided with a wire inlet hole 190; one end of the cleaning barrel 150 is in contact with the retaining ring 230, and the other end is in contact with the chamber cover 180. In this embodiment, by providing the chamber cover 180, it is possible to prevent the attachments in the cleaning barrel 150 from being directly discharged along the feed end, causing environmental pollution; in addition, by providing the retaining ring 230 and the chamber cover 180, the cleaning barrel 150 can be limited to the cleaning chamber 130 to prevent it from being displaced along the axial direction.

[0030] Further, such as Figure 4 As shown, when the yarn in the yarn storage drum 210 is transmitted to the wire inlet hole 190, it does not maintain a horizontal state, which may easily cause wear between the yarn and the wall of the wire inlet hole 190. Figure 3 and 4 As shown, a guide roller 220 is horizontally arranged on the support frame 110, and the top end of the guide roller 220 is arranged between the top and bottom ends of the wire feed hole 190, so that the degree of wear between the yarn and the wall of the wire feed hole 190 can be greatly reduced.

[0031] Further, on the basis of Example 1 or Example 2, on the two surfaces of the cleaning cylinder 150 and the cleaning chamber 130 that contact each other, one surface is provided with a plurality of sliders 160, and the other surface is provided with a plurality of slide grooves 170 that slide in cooperation with the sliders 160. By providing the sliders 160 and the slide grooves 170, the smoothness of taking and placing the cleaning cylinder 150 can be improved, and at the same time, the cleaning cylinder 150 is limited to prevent it from rotating around the axis.

[0032] In the description of this patent, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "longitudinal", "horizontal" and the like indicate the orientation or position relationship based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing this patent and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of this patent.
