The utility model has novel structure and is easy to operate.

[0004] However, when the above-mentioned prior art is in use, the cotton thread enters the yarn guide hole and is pressed on the rounded corner, which plays a tensioning role. The tensioning effect is general. At this time, the cotton thread contacts the rounded corner surface and the connection between the inner groove and the yarn guide hole. The cotton thread is easy to break during the winding process, and the state of the cotton thread cannot be monitored in time. The breakage of any one or more cotton threads will affect the quality of the cotton thread plying. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0026] See also Figures 1 to 4 In the utility model, the cotton thread plying and reforming machine comprises a frame 100, a plurality of tensioning mechanisms 200 and a plurality of detection mechanisms 300.

[0027] The frame 100 includes a base frame 101, the top of the base frame 101 is fixedly connected to a front frame 102 and a rear frame 103, and the side of the front frame 102 away from the rear frame 103 is fixedly connected to a side frame 104; each tensioning mechanism 200 includes a holder 201, a connecting frame 202, a guide wheel 203, a lower tensioning wheel 204 and an upper tensioning wheel 205, the holder 201 is fixedly connected to the top of the rear frame 103 and is spaced apart along the length direction of the rear frame 103; each detection mechanism 300 includes an optical fiber sensor 301 and an optical fiber amplifier 302, the optical fiber sensor 301 and the optical fiber amplifier 302 are fixedly installed on the front frame 102 and are spaced apart along the length direction of the front frame 102.

[0028] In this embodiment, preferably, a plurality of wire holes 105 for passing the cotton thread are provided on the front frame 102, and the positions and number of the wire holes 105 correspond to the number and positions of the upper tensioning wheel 205 and the optical fiber sensor 301. The two ends of the wire holes 105 are rounded at the junction with the two sides of the front frame 102, and the side frame 104 is provided with a joint hole 106, and the two ends of the joint hole 106 are rounded at the junction with the two sides of the side frame 104.

[0029] Specifically, when the cotton thread passes through the wire hole 105 and the stranding hole 106, it contacts the front frame 102 and the side frame 104 through the rounded corners, thereby reducing the probability of the cotton thread breaking.

[0030] In this embodiment, preferably, the connecting frame 202 is fixedly connected to the side of the card seat 201, the wire wheel 203 is rotatably connected to the lower inner side of the connecting frame 202, the inner side of the connecting frame 202 is hingedly installed with a lower connecting rod 206 and an upper connecting rod 207 from bottom to top, the lower tensioning wheel 204 and the upper tensioning wheel 205 are respectively hingedly installed at the lower connecting rod 206 and the end of the upper connecting rod 207 away from the connecting frame 202, a lower spring 208 is installed between the lower connecting rod 206 and the inner wall of the connecting frame 202, and an upper spring 209 is installed between the upper connecting rod 207 and the inner wall of the connecting frame 202;

[0031] Specifically, after the cotton thread passes around the wire wheel 203, the lower tensioning wheel 204 and the upper tensioning wheel 205 in sequence, as the cotton thread is wound, the cotton thread applies tension and pressure to the lower tensioning wheel 204 and the upper tensioning wheel 205 respectively, and the lower tensioning wheel 204 and the upper tensioning wheel 205 are subjected to the force and act on the lower spring 208 and the upper spring 209 through the lower connecting rod 206 and the upper connecting rod 207 respectively. The lower spring 208 and the upper spring 209 are deformed under the force and generate elastic force to restore their shape. The elastic force generated by the lower spring 208 and the upper spring 209 can act on the lower connecting rod 206 and the upper connecting rod 207 respectively, thereby causing the lower tensioning wheel 204 and the upper tensioning wheel 205 to tension the cotton thread, with a good tensioning effect, which is convenient for subsequent use.

[0033] Specifically, when the cotton thread has not passed through the optical fiber sensor 301 and the wire hole 105, there is no cotton thread within the detection range of the optical fiber sensor 301. At this time, the threshold value of the optical fiber amplifier 302 is set. When the cotton thread passes through the optical fiber sensor 301 and the wire hole 105, the light source of the optical fiber sensor 301 generates light which is reflected or scattered after being transmitted to the surface of the cotton thread through the optical fiber. The value of the optical fiber amplifier 302 changes. When a cotton thread breaks, there is no cotton thread within the detection range of the optical fiber sensor 301 that detects the cotton thread. The detection value of the optical fiber amplifier 302 returns to the threshold value, and an alarm or shutdown can be performed. The equipment and control system for alarm or shutdown are prior art and will not be elaborated on again.

[0034] In this embodiment, preferably, a plurality of horizontal frames 107 are fixedly connected to the inner side of the rear frame 103 from top to bottom, and uniformly distributed cotton yarn roll placement racks 400 are fixedly connected to the horizontal frames 107, and adjacent cotton yarn roll placement racks 400 are staggered in the horizontal and vertical directions, and each cotton yarn roll placement rack 400 includes a stopper 401 fixedly connected to the horizontal frame 107, and a fixed shaft 402 is fixedly connected to the front side of the stopper 401, and one end of the fixed shaft 402 away from the stopper 401 is threadedly connected to a limiting block 403;

[0037] The cotton yarn roll can be placed on the fixed shaft 402, and the limit block 403 is screwed on the fixed shaft 402 to place the cotton yarn roll and fall. The multiple strands of cotton thread are passed around the wire wheel 203, the lower tensioning wheel 204 and the upper tensioning wheel 205 in turn, and then pass through the optical fiber sensor 301 and the wire hole 105 in turn, and are integrated into a strand of cotton thread at the stranding hole 106. As the cotton thread is rolled up, the cotton thread applies tension and pressure to the lower tensioning wheel 204 and the upper tensioning wheel 205 respectively, and the cotton thread is tensioned by the elastic force of the lower spring 208 and the upper spring 209, and the tensioning effect is good, which is convenient for subsequent use;

[0038] During the process of plying the cotton threads, the cotton threads pass through the optical fiber sensor 301. The light source of the optical fiber sensor 301 generates light which is transmitted to the surface of the cotton threads through the optical fiber and then reflected or scattered. The value of the optical fiber amplifier 302 changes. When a cotton thread breaks, there is no cotton thread within the detection range of the optical fiber sensor 301 that detects the cotton thread.
