[0033] As Figs. 1-2 shown, a non-woven fabric detection device, comprising: feeding roller 1, detection bin 2, discharge roller 3 arranged in turn along the direction of non-woven fabric running;

[0034] The detection bin 2 is provided with an inlet 21 on the side close to the feeding roller 1 and an outlet 22 on the side close to the discharging roller 3. The detection bin 2 is sequentially provided with a first guide rod 23, a first guide roller 24, a second guide roller 25 and a second guide rod 26 along the direction in which the non-woven fabric travels. The first guide rod 23 and the second guide rod 26 are used to change the direction in which the non-woven fabric travels. The first guide rod 23, the first guide roller 24, the second guide roller 25 and the second guide rod 26 combine to make the non-woven fabric in the detection bin 2 bend in multiple ways, increase the tension of the non-woven fabric and ensure that the non-woven fabric is in a horizontal state and passes between the first guide roller 24 and the second guide roller 25.

[0035] The detection bin 2 is further provided with a detection device arranged between the first guide roller 24 and the second guide roller 25, a spraying pump 5 and a control unit 6. The detection device includes an infrared emitter 41 and an infrared receiver 42. The infrared emitter 41 and the infrared receiver 42 are oppositely arranged and respectively located below and above the non-woven fabric. The non-woven fabric is located between the light paths of the infrared emitter 41 and the infrared receiver 42. The spraying head of the spraying pump 5 is located between the detection device and the second guide roller 25 and faces the non-woven fabric. The control unit 6 is electrically connected with the detection device and the spraying pump 5. The control unit 6 controls the spraying pump 5 to work according to the information fed back by the detection device.

[0036] Further, the non-woven fabric detection device further includes a driving motor (not shown in the figure). The driving motor is used to drive the feeding roller 1 and the discharging roller 3 to rotate synchronously. The driving motor drives the feeding roller 1 and the discharging roller 3 to rotate synchronously at a set speed through gear or belt transmission.

[0037] Further, the detection bin 2 is further provided with a connecting rod 27 and an air cylinder 28. The second guide rod 26 is arranged between the second guide roller 25 and the outlet 22 through the connecting rod 27. The bottom end of the connecting rod 27 is hinged to the side wall of the detection bin 2. One end of the air cylinder 28 is hinged to the side wall of the detection bin 2 and the other end is hinged to the connecting rod 27. The tension of the non-woven fabric is adjusted through the connecting rod 27 and the air cylinder 28 so that the non-woven fabric is kept in a tensioned and flat state.

The first guide roller 24 and the second guide roller 25 make the non-woven fabric in the detection bin 2 pass through the detection device and the material spraying pump 5 in a horizontal state. The infrared emitter 41 in the detection device emits detection light towards the infrared receiver 42, but the non-woven fabric in the middle of the light path blocks the detection light; if the infrared receiver 42 receives a receiving light with a relatively strong light intensity, it indicates that there is a hole in the non-woven fabric at this position, and the detection device sends a detection abnormality signal to the control unit 6; the control unit 6 receives the abnormality signal, controls the material spraying pump 5 to spray after a preset delay, so as to spray the pigment to the non-woven fabric more accurately, indicating that there is a hole in the non-woven fabric.

[0043] The technical solutions in the embodiments of the application have at least the following technical effects or advantages:

[0044] 1. The non-woven fabric detection device can comprehensively detect the holes in the non-woven fabric and automatically mark, which is convenient for subsequent personnel to check.

[0045] 2.
