[0022] The utility model will be further described below in combination with the drawings and examples:

[0023] As shown in the example, Figure 1 、 Figure 2 、 Figure 3 The feeding frame broken strip accumulation detection structure includes feeding frame 1, and further includes:

[0024] Lower roller 2 is arranged at the side of feeding frame 1;

[0025] Upper roller 3 is arranged above lower roller 2;

[0026] Photoelectric sensor 4 is arranged at the side of feeding frame 1, and the gap between the electric sensor 4 and lower roller 2 is provided.

[0027] When feeding the broken strip, the broken strip will be accumulated at the lower roller 2, and the broken strip will shield the photoelectric sensor 4 with the rotation of the lower roller 2, and then the photoelectric sensor 4 will transmit the signal to the control center, and the control center controls the machine to stop; The detection structure is simple, and the labor intensity is reduced.

[0028] As shown in the example, Figure 1 、 Figure 2As shown, the upper roller 3 is at least two, the photoelectric sensor 4 is a pair of photoelectric sensors, which are respectively arranged at the front and rear ends of the feeding frame 1. The pair of photoelectric sensors has long distance detection capability, and the upper roller 3 has multiple, which can perform long distance accurate detection when the sliver is fed with high efficiency.

[0029] As shown in the embodiment, Figure 2 、 Figure 3 The feeding frame 1 includes a panel 11 and a support 12, the side edge part of the panel 11 is located outside the support 12, and the photoelectric sensor 4 is located below the panel 11 outside the support 12. The panel 11 above the photoelectric sensor 4 is used to prevent external objects from interfering with the photoelectric sensor 4, and to ensure the accuracy of the detection of the photoelectric sensor 4.

[0030] As shown in the embodiment, Figure 2 、 Figure 3 The side edge of the panel 11 is provided with a folding edge 5, which is inclined towards one side of the support 12. The folding edge 5 makes the bending part of the panel 11 smooth, avoids damage to the fibers when the sliver enters from the side of the panel 11, and also prevents external objects from interfering with the photoelectric sensor 4 from the side.

[0031] As shown in the embodiment, Figure 1 、 Figure 2 The front of the upper roller 3 is provided with a sliver guide ring 6, which is installed on the side edge of the feeding frame 1. The sliver enters the drafting area through the annular channel of the sliver guide ring 6, avoiding the deviation or intersection of the sliver.

[0032] In the embodiment, the sliver guide ring 6 is made of ceramic material. The sliver guide ring 6 made of ceramic material has a smooth surface, which can effectively reduce the friction coefficient with the sliver and avoid fiber damage; at the same time, it has anti-static properties, significantly reduces lint adsorption, and has good wear resistance and long service life.
