Specifically, the friction reducing assembly 7 includes a front cone 71, a rear cone 72, a plurality of front magnets 73, and a plurality of rear magnets 74; wherein, preceding cone 71, back cone 72 all are awl tube-shaped structure, and preceding cone 71 is coaxial to be set firmly in the one end that rotates cover 62 periphery and is close to fixed cover 61, and back cone 72 is coaxial to be set firmly in the one end that fixed cover 61 periphery is close to rotating cover 62, and preceding cone 71, the conical surface of back cone 72 all arrange towards flabellum 63, promptly, preceding cone 71, the conical surface of back cone 72 all arrange forward.
The front magnet 73 and the rear magnet 74 are both permanent magnets, and the front magnet 73 and the rear magnet 74 are mutually in repulsive fit, specifically, the number of the front magnet 73 and the rear magnet 74 in the embodiment is three, the three front magnets 73 are uniformly distributed along the mounting rod 6 as an axis, and the three front magnets 73 are all fixedly arranged on the inner periphery of the front cone 71; the three rear magnets 74 are uniformly distributed along the mounting rod 6 as an axis, and the three rear magnets 74 are fixedly arranged on the periphery of the rear cone 72; that is, the three front magnets 73 are provided in one-to-one correspondence with the three rear magnets 74.
In the process that the fan blades 63 are driven to rotate by airflow flowing in the blast pipe 2, because the front magnet 73 and the rear magnet 74 are in mutual repulsion fit, contact friction force is not easy to generate between the fixed sleeve 61 and the rotating sleeve 62, so that the rotating speed of the fan blades 63 is increased, the fan blades 63 are favorable for disturbing the airflow direction in the blast pipe 2, and metal dust is not easy to settle and accumulate on the inner wall of the blast pipe 2. In addition, because the front magnets 73 and the rear magnets 74 are arranged at intervals, the mutually repulsive magnetic forces applied to the fan blades 63 when the fan blades 63 rotate to different positions are different, so that the fan blades 63 continuously shake back and forth along the axis direction of the mounting rod 6 under the combined action of the magnetic force and the air flow impact force, which is beneficial to disturbing the air flow direction in the air supply pipe 2 by the fan blades 63, and metal dust is not easy to settle and accumulate on the inner wall of the air supply pipe 2. In addition, the fan blade 63 shaking back and forth can shake the air flow in the blast pipe 2 to drive the flexible sleeve 31 to shake, so that the metal dust is not easy to settle and accumulate on the inner wall of the flexible sleeve 31.
In the embodiment, the mounting plate 41 is fixed to one side of the laser welding machine 10 through a preset lifting assembly 8, that is, the lifting assembly 8 is arranged between the mounting plate 41 and the laser welding machine 10, and the lifting assembly 8 can adjust the height position of the air inlet cover 3 according to actual conditions.
Specifically, the lifting assembly 8 comprises a vertical rod 81, a lifting rod 82 and a locking member 83; the vertical rod 81 is vertically and fixedly arranged on the laser welding machine 10, the lifting rod 82 is of an inverted L-shaped structure, the top of the lifting rod 82 is vertically and fixedly arranged on one side, away from the air supply pipe 2, of the mounting plate 41, the bottom of the lifting rod 82 is provided with a lifting groove in sliding fit with the vertical rod 81, and the lifting rod 82 is slidably sleeved on the top of the vertical rod 81, so that the height can be adjusted in a sliding manner between the vertical rod 81 and the lifting rod 82; retaining member 83 is the bolt, retaining member 83 threaded connection in the lifter 82 bottom, and retaining member 83 and montant 81 looks butt to realize the locking after the height-adjusting that slides between montant 81, the lifter 82.
When the clamping position height of the aluminum shell changes, the height of the generated metal dust changes synchronously, the height of the air inlet cover 3 is adjusted by the locking of the locking piece 83 through the sliding adjustment height between the vertical rod 81 and the lifting rod 82, and the air inlet cover and the metal dust are matched in position, so that the suction effect is improved.
Referring to fig. 1, in the present embodiment, a trap 9 is disposed at an end of the air supply pipe 2 close to the dust removal filter 1, and a filtering liquid is pre-disposed in the trap 9, and the filtering liquid is water; three dispersing grids 91 which are arranged at intervals are fixedly arranged in the trap 9, and a valve switch 92 for replacing filtrate is arranged at the bottom of the trap 9.
When the dust removal filter 1 sucks metal dust generated in the laser welding process of the aluminum shell through the air supply pipe 2 and the air inlet cover 3, air mixed with the metal dust flows through the trap 9 and is in contact with a filter liquid under the dispersion effect of the dispersion grid 91, so that part of the metal dust is dissolved in a water body, and the filtering pressure of the dust removal filter 1 is reduced in a pretreatment mode.
In this embodiment, the observation window has been seted up to trapway 9 one side, and the fixed closing cap of observation window has transparent plate 93, and transparent plate 93 is glass, sees through transparent plate 93 and can observe the muddy degree of the filtrate in trapway 9 to in time change.
The implementation principle is as follows: when the adjusting assembly 44 drives the four synchronizing gears 42 to rotate synchronously, the four elastic telescopic rods 43 rotate synchronously to drive the four adjusting wheels 5 to adjust the position, so that the shape of the belt support ring 32 is changed, that is, the length-width ratio of the rectangular opening formed by the flexible sleeve 31 is changed, thereby adjusting the size of the air inlet cover 3, and under the condition that the pumping power provided by the dust removal filter 1 is not changed, the air speed of the air inlet is adjusted by adjusting the size of the opening of the air inlet cover 3.
