[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-5An embodiment of this utility model provides a dust-collecting exhaust hood for a cleaning and packaging section, comprising a base 1, a column 2, a rotating mechanism 3, a lifting and sealing mechanism 4, and a placement mechanism 5. The column 2 is welded to the top of the base 1, the rotating mechanism 3 is rotatably connected to the top of the column 2, the lifting and sealing mechanism 4 is fixedly connected to the right side of the rotating mechanism 3, and the placement mechanism 5 is welded to the right side of the base 1.
[0029] Furthermore, the rotating mechanism 3 includes a fixed disk 301, a rotating column 302, a crossbeam 303, a support plate 304, a bidirectional control motor 305, a drive gear 306, and a driven gear 307. The driven gear 307 is rotatably connected to the top of the column 2, and the driven gear 307 is fixedly connected to the fixed disk 301. The fixed disk 301 is fixedly connected to the rotating column 302. The crossbeam 303 is welded to the top of the rotating column 302. The support plate 304 is welded to the left side of the top of the column 2. The bidirectional control motor 305 is fixedly connected to the bottom of the support plate 304. The drive gear 306 is fixedly connected to the output shaft of the bidirectional control motor 305. The drive gear 306 meshes with the driven gear 307. The bidirectional control motor 305 is electrically connected to an external controller. The controller causes the bidirectional control motor 305 to rotate bidirectionally, thereby driving the drive gear 306 and the driven gear 307 to make the crossbeam 303 rotate orderly around the column 2.
[0030] Furthermore, the lifting and sealing mechanism 4 includes an electric telescopic rod 401, an elastic damper 402, a sealing cover 403, a bellows 404, and an exhaust pipe 405. The electric telescopic rod 401 is fixedly connected to one end of the crossbeam 303. The elastic damper 402 is fixedly installed at the bottom output end of the electric telescopic rod 401. The bottom end of the elastic damper 402 is fixedly connected to the sealing cover 403. The top end face of the sealing cover 403 is provided with an opening and is fixedly connected to one end of the bellows 404. The other end of the bellows 404 is fixedly connected to the exhaust pipe. 405, the exhaust pipe 405 is fixedly connected to the crossbeam 303. One end of the exhaust pipe 405 is connected to an external exhaust fan. The sealing cover 403 can be raised and lowered by extending and retracting the electric telescopic rod 401. When the sealing cover 403 comes into contact with the ladle, the elastic damper 402 can effectively absorb the impact energy, significantly reduce vibration, protect the equipment and extend its service life. The corrugated pipe 404, with its flexible structure, can ensure that the connection between the exhaust pipe 405 and the sealing cover 403 has good flexibility and compensation ability, and can adapt to relative displacement.
[0031] Furthermore, the placement mechanism 5 includes a placement seat 501 and a placement groove 502. The placement seat 501 is welded to the right side of the base 1. The placement groove 502 is opened on the top of the placement seat 501. A sealing gasket is set at the upper end of the placement seat 501. The placement groove 502 is a trapezoidal shape that is wider at the top and narrower at the bottom. The placement groove 502 corresponds to the position of the sealing cover 403. Placing the ladle into the placement seat 501 can improve its placement stability. At the same time, the limiting design of the placement groove 502 can effectively prevent the ladle from shifting, ensure accurate positioning, and ensure safe and reliable use in the future.
[0032] Working principle: First, the ladle is placed in the placement seat 501, which improves its stability. Simultaneously, the limiting design of the placement slot 502 effectively prevents the ladle from shifting, ensuring precise positioning and guaranteeing safe and reliable subsequent use. Next, the bidirectional control motor 305 drives the drive gear 306, which in turn drives the fixed disk 301 via the driven gear 307, thereby realizing the rotation of the rotating column 302 and the crossbeam 303. The fixed disk 301 can withstand large radial loads, axial loads, and overturning moments, improving the rotation of the rotating column 302 and the crossbeam 303. To ensure stability during rotation, the electric telescopic rod 401 retracts, allowing the sealing cover 403 to rise and prevent collisions during rotation. Then, the electric telescopic rod 401 extends, and the sealing cover 403 covers the ladle. When the sealing cover 403 contacts the ladle, the elastic damper 402 effectively absorbs impact energy, significantly reduces vibration, protects the equipment, and extends its service life. At the same time, the bellows 404, with its flexible structure, ensures that the connection between the exhaust pipe 405 and the sealing cover 403 has good flexibility and compensation capability, adapting to relative displacement.
