DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0023] Please refer to Figures 1 to 4The application provides a dust suction device for transformer insulation board engraving, which comprises a dust suction cover 1, a dust suction pipeline 2 connected to the side of the dust suction cover 1, and a ring brush 3 connected to the bottom of the dust suction cover 1. The ring brush 3 can be locked to the dust suction cover 1 by a clamp, so that the flying of dust and impurities during the engraving process can be avoided, and a good blocking effect can be achieved. A movable auxiliary cleaning mechanism is connected to the inside of the dust suction cover 1. The auxiliary cleaning mechanism comprises a gas cylinder 14, a second motor 8 and a brush head 9. The gas cylinder 14 is used to drive the second motor 8 to lift and lower. The power output end of the second motor 8 is connected to the brush head 9. The gas cylinder 14 is connected to a driving mechanism used to drive the gas cylinder 14 to rotate. A liftable ring plate 10 is connected to the inside of the dust suction cover 1. The ring plate 10 is connected to the second motor 8. The ring plate 10 is connected to a plurality of pressing plates 19. The included angles of adjacent pressing plates 19 are equal and are arranged obliquely. The pressing plates 19 are matched with a beating mechanism connected to the inside of the dust suction cover 1.

[0024] The dust suction cover 1 and the engraving knife are respectively driven by separate driving devices, that is, the engraving knife can perform lifting and high-speed rotating movements, and the dust suction cover 1 can perform lifting movements. When the engraving knife performs engraving work on the plate, the driving device drives the dust suction cover 1 to move downward, so that the ring brush 3 is pressed on the surface of the plate. The external dust suction mechanism is connected to the dust suction pipeline 2, so that negative pressure is generated in the inside of the dust suction cover 1. External gas passes through the ring brush 3 into the dust suction cover 1. The ring brush 3 plays a blocking role to avoid the flying of dust and impurities. After long-term use, more impurities are attached to the inside of the ring brush 3, so that the external gas is blocked from entering the dust suction cover 1, thereby affecting the dust suction effect. The above is the prior art.

[0025] During the engraving process, the gas cylinder 14 can drive the motor base 16, the second motor 8, the rotating shaft 15 and the brush head 9 to synchronously lift and lower. The second motor 8 drives the brush head 9 to rotate at high speed, so that the brush head 9 extends into the engraved groove, thereby facilitating the re-cleaning of the attached burrs and impurities. After cleaning, the impurities are immediately sucked into the dust suction pipeline 2, thereby improving the engraving effect. At the same time, the lifting of the motor base 16 can drive the connecting rod 17 to lift and lower. The connecting rod 17 can drive the ring plate 10 to move. The ring plate 10 drives the plurality of pressing plates 19 to lift and lower, so that the end of the pressing plate 19 slides in the inside of the flap 20. The beating plate 11 at the end of the flap 20 is reciprocally moved. The beating plate 11 intermittently beats the ring brush 3, so that the impurities attached to the inside of the ring brush 3 are cleaned. The cleaning property of the ring brush 3 is improved, so that the external gas can more smoothly enter the inside of the dust suction cover 1, thereby facilitating the adsorption of dust and impurities by the dust suction cover 1.

[0026] The auxiliary cleaning mechanism further comprises a connecting seat 13, a motor base 16 and a rotating shaft 15. The connecting seat 13 is connected to the driving mechanism and connected to the top of the gas cylinder 14. The power output end of the gas cylinder 14 is connected to the motor base 16.

The vertical grooves 12 play a guiding role on the annular plate 10, making the annular plate 10 stable in lifting and unable to rotate, so that the end of the pressing plate 19 can be accurately pressed on the inner side of the warped plate 20, avoiding skewing and affecting the work of the beating mechanism.

[0028] The driving mechanism includes the motor 4, the gear ring 5, and the gear head 7, the power output end of the motor 4 is connected to the gear head 7, the gear head 7 is used to drive the gear ring 5 to rotate, and the gear ring 5 is connected to the auxiliary cleaning mechanism. The motor 4 can drive the gear head 7 to rotate, the gear head 7 drives the gear ring 5 to rotate, and then the rotation of the auxiliary cleaning mechanism is realized, the position of the brush head 9 can be changed, and the auxiliary cleaning mechanism is suitable for grooves at different positions and has strong applicability. In the rotation process of the auxiliary cleaning mechanism, the sliding block 18 can slide on the annular plate 10, and the auxiliary cleaning mechanism is guided and rotated stably.

[0029] The gear head 7 is connected to the gear ring 5 in meshing, the gear ring 5 is rotationally connected to the annular groove 6 arranged at the top end in the dust cover 1, and the stability of the rotation of the gear ring 5 is improved.

[0030] The beating mechanism includes the beating plate 11, the warped plate 20, and the support plate 21, the beating plate 11 is connected to the end of the warped plate 20, one end of the support plate 21 is connected to the dust cover 1, and the other end is rotationally connected to the support plate 21 through a torsional spring. When the pressing plate 19 descends, the end of the pressing plate 19 slides on the inner side of the warped plate 20, the beating plate 11 moves towards the direction of the annular brush 3, the annular brush 3 is beaten, and at this time, the torsional spring is in a winding state. When the pressing plate 19 moves upwards, the end of the pressing plate 19 gradually separates from the warped plate 20, the elastic force of the wound torsional spring is released, and the beating plate 11 is driven to return to the original position. That is, the beating plate 11 swings and beats the annular brush 3 when the pressing plate 19 ascends and descends, and the beating operation is realized, so that the cleaning purpose is achieved without manual operation.

[0031] The end of the pressing plate 19 is in an arc structure, and the end of the pressing plate 19 matches the groove in the inner side of the support plate 21.

[0032] According to the size of the dust cover 1, a corresponding number of beating plates 11 are rotated, usually three beating plates 11 are arranged, and the adjacent included angle is 120 degrees, so that the annular brush 3 can be beaten comprehensively, and the effect is remarkable.
