as shown in fig. 1 to 11, in the present embodiment, a ninth embodiment is further described, in which transparent glass is bonded to both the rear end of the upper observation frame 1-6 and the inside of the observation groove 2-5.
The working principle of the invention is as follows: a device needing paint spraying is fixedly connected to a fixed seat 4-5 through a fixed threaded hole 4-6, and a rotating baffle 4-3 rotates in a plane bearing rotating groove 1-5 through a plane rotating bearing 4-4 by manually rotating a rotating plate 4-1 and a central rotating shaft 4-2, so that the device to be painted can rotate to receive larger area and uniform paint spraying; powder is added through the powder adding communicating pipe 3-1, the powder is uniformly distributed to three powder paint spraying guns 3-5 through the flow distribution box 3-2, then a device needing paint spraying is sprayed, the L-shaped adjusting plate 3-3 is driven to move up and down through rotating the adjusting bolts 3-4 and matching with the threads of the L-shaped adjusting plate 3-3, then the three powder paint spraying guns 3-5 and the cross sliding seat 3-6 are driven to move up and down in the cross sliding groove 1-2, and then the position of paint spraying is adjusted; after the paint spraying is finished, most of the powder flows out through the conical recovery receiving bobbin 1-8; flowing gas-solid mixture flows to a downward recovery circulating pipe 2-2 through a conical recovery receiving bobbin pipe 1-8, solid powder is sequentially sieved on three filter screen seats 2-8 in a rectangular cylinder 2-6 after the gas flow is discharged, and the gas flow is discharged out of the rectangular cylinder 2-6 after the gas flow is discharged; the driving motor 5-2 is electrified to drive the driving conical gear 5-3 to rotate, the driving rotating shaft 5-5 is driven to rotate by meshing with the conical round combined gear 5-4, the driving rotating seat 5-6 and the driving convex ring 5-7 are further driven to rotate, the driven gear 5-8 is driven to rotate by the rotating conical round combined gear 5-4, the plurality of internal connecting rods 5-10, the internal rotating shaft 5-11 and the two conical fan-shaped powder collecting rods 5-12 are driven to rotate in the conical recovery receiving bobbin 1-8 by the sealed rotation between the conical recovery receiving bobbin 1-8 and the lower recovery circulating pipe 2-2 through the sealed rotating seat 5-9, the two conical fan-shaped powder collecting rods 5-12 push the powder falling in the conical recovery receiving bobbin 1-8, making it fall and be recovered; the rotating inner rotating shaft 5-11 drives the lower rotating base 5-13 and the plurality of anti-blocking propulsion fins 5-14 to rotate, and then the plurality of anti-blocking propulsion fins 5-14 stir and push the powder falling in the lower recovery circulating pipe 2-2, so that the powder is discharged out of the rectangular cylinder 2-6 through airflow and is recovered; the rotary driving convex ring 5-7 rotates in the arc-shaped extrusion groove 6-5, the driving connecting plate 6-3 is intermittently extruded through the boss, the two reset springs 6-4 are further extruded to enable the driving connecting plate 6-3 to face downwards, the driving connecting plate 6-3 is intermittently reciprocated up and down, the three sealing sliding plates 6-6 and the brushes 6-7 are further driven to intermittently reciprocate up and down, the brushes 6-7 clean the filter screens on the three filter screen seats 2-8, powder adhered to the filter screens falls into the powder recovery cylinder 7 to be recovered, meanwhile, the filter screens are prevented from being blocked, and all the powder falls into the powder recovery cylinder 7 through the recovery grooves 2-9 to be recovered; the paint spraying process can be adjusted in the powder paint spraying process, the powder leakage is prevented, the paint spraying effect is guaranteed, and the operation is convenient; separating the powder through a plurality of layers of filter screens to enable the airflow to flow out and recover the powder; in the process of powder recovery, the powder recovery efficiency is high, and simultaneously, the blocking of the powder in the flow recovery process is prevented.
The above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and variations, modifications, additions and substitutions which may be made by those skilled in the art within the spirit of the present invention are within the scope of the present invention.
