[0017] The dust collector filter bag damage online detection mechanism is provided with a detection module, etc., when in use, the mounting plate is installed on the inner side wall of the dust collector, and each detection module is located below the filter bag. When it is necessary to perform online detection of filter bag damage, the detection module is driven to move upward by the lifting module and the moving frame, so that the rotating ring is set on the side wall of the filter bag and moves to the top of the side wall of the filter bag. Then, the exhaust fan is started, and each annular cover is exhausted through the exhaust pipe and the U-shaped pipe, so that the adsorption holes are exhausted and the filter bag is adsorbed on the inner wall of the rotating ring to make it open and avoid being sunken. At the same time, the first electromagnet is powered off. At this time, under the action of the first spring, the end of the detection rod is aligned with the filter. The side walls of the filter bag are against each other, and when air enters the fixed box, it will impact the side walls of the baffle, causing the rotating rod to rotate. The rotation of the rotating rod drives the rotation of the gear, thereby driving the gear ring to rotate, and then driving the first connecting ring and the rotating ring to rotate. At the same time, when the first connecting ring rotates, it drives the first L-shaped plate and the detection rod to rotate synchronously, so that the end of the detection rod can slide on the side wall of the filter bag. When the filter bag is damaged, the detection rod will be inserted into the filter bag under the action of the first spring.

At this time, the filter bag can be determined by detecting the distance change of the moving plate through the distance sensor. The damage of the filter bag can be detected by the detection module, and the detection module can be moved by the lifting module to carry out a comprehensive detection of the side wall of the filter bag, so as to facilitate a comprehensive damage detection of the filter bag, the detection is more convenient and quick, and the accuracy of the detection result is guaranteed; by setting a cleaning mechanism, when the detection is carried out, when the rotating ring rotates, the second connecting ring is driven to rotate, and the first moving ring and the bristles are driven to rotate by the second resetting mechanism, so that the bristles can clean the surface of the first moving ring. At the same time, when the first moving ring rotates, the push rod is driven to rotate synchronously. When the push rod is against the side wall of the triangular plate, the first moving ring and the bristles are pushed downward, and at the same time, the third spring is compressed. When the push rod passes over the triangular plate, the first moving ring and the bristles can move upward and reset under the action of the third spring. At the same time, the second electromagnet is energized to attract the second iron block, so that the second moving ring and the push ring move upward. At the same time, the fourth spring is compressed, and the push ring moves upward, which can push the bristles to tilt upward and separate from the filter bag. When the first moving ring moves downward, the second electromagnet is de-energized. At this time, the push ring and the second moving ring can move downward and reset under the action of the fourth spring, so that the bristles can reset and resist the side wall of the filter bag. This reciprocating process can clean the side wall of the filter bag from top to bottom, and can also flatten the filter bag, thereby ensuring the accuracy of subsequent detection.

When the first movable ring 702 and the bristles 703 move upward and reset, the second electromagnet 906 is energized to attract the second iron block 907, so that the second movable ring 902 and the pushing ring 901 move upward. At the same time, the fourth spring 905 is compressed, and the pushing ring 901 moves upward, which can push the bristles 703 to tilt upward and disengage from the filter bag.

[0038] Working principle: When in use, the mounting plate 1 is mounted on the inner wall of the dust collector, and each detection module 12 is placed below the filter bag. When it is necessary to perform online detection of filter bag damage, the detection module 12 is driven to move upward by the lifting module 13 and the moving frame 11, so that the rotating ring 1202 is sleeved on the side wall of the filter bag and moves to the top of the side wall of the filter bag. Then, the exhaust fan 403 is started, and each annular cover 1201 is exhausted through the exhaust pipe 402 and the U-shaped pipe 401, so that the adsorption hole 1203 is exhausted, and the filter bag is adsorbed on the inner wall of the rotating ring 1202 to make it open and avoid depression.

[0039] At the same time, the first electromagnet 1209 is powered off. At this time, under the action of the first spring 202, the end of the detection rod 1206 is against the side wall of the filter bag, and when air enters the fixed box 601, it will impact the side wall of the baffle 603, causing the rotating rod 602 to rotate. The rotation of the rotating rod 602 drives the rotation of the gear 502, thereby driving the gear ring 501 to rotate, and then driving the first connecting ring 1204 and the rotating ring 1202 to rotate. At the same time, when the first connecting ring 1204 rotates, it drives the first L-shaped plate 1205 and the detection rod 1206 to rotate synchronously, so that the end of the detection rod 1206 can slide on the side wall of the filter bag.

[0040] Furthermore, when the rotating ring 1202 rotates, the second connecting ring 701 is driven to rotate, and the first moving ring 702 and the bristles 703 are driven to rotate through the second reset mechanism 8, so that the bristles 703 can clean the surface of the first moving ring 702. At the same time, when the first moving ring 702 rotates, the push rod 1004 is driven to rotate synchronously. When the push rod 1004 abuts against the side wall of the triangular plate 1003, the first moving ring 702 and the bristles 703 are pushed to move downward. At the same time, the third spring 804 is compressed. When the push rod 1004 passes over the triangular plate 1003, the first moving ring 702 and the bristles 703 can move upward and reset under the action of the third spring 804.

[0041] At the same time, the second electromagnet 906 is energized to attract the second iron block 907, so that the second moving ring 902 and the pushing ring 901 move upwards. At the same time, the fourth spring 905 is compressed, and the pushing ring 901 moves upwards, which can push the bristles 703 to tilt upwards and separate from the filter bag. When the first moving ring 702 moves downwards, the second electromagnet 906 is powered off. At this time, the pushing ring 901 and the second moving ring 902 can move downwards and reset under the action of the fourth spring 905, so that the bristles 703 can reset and abut against the side wall of the filter bag. This reciprocating process can clean the side wall of the filter bag from top to bottom, and can also flatten the filter bag, thereby ensuring the accuracy of subsequent detection.

[0042] When the filter bag is damaged, the detection rod 1206 will be inserted into the filter bag under the action of the first spring 202, and at the same time, it will drive the disc 1212 to move and abut against the inclined surface 1211, thereby pushing the movable plate 1210 to move in the direction close to the L-shaped block 1213. At this time, the damage of the filter bag can be determined by detecting the distance change of the movable plate 1210 through the distance sensor 1214, and the detection module 12 can be moved by the lifting module 13 to comprehensively detect the side wall of the filter bag, thereby facilitating a comprehensive damage detection of the filter bag, making the detection more convenient and quick, and ensuring the accuracy of the detection result.
