Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying equipment, in particular to a paint spraying equipment. Background Art

[0002] Excavator bucket teeth are important consumable parts on the excavator. They are similar to human teeth and are composed of a tooth seat and a tooth tip. The two are connected by a pin shaft. Since the tooth tip is worn and failed, only the tip needs to be replaced. Excavator bucket teeth need to be painted during the production process to prevent severe wear of the bucket teeth.

[0003] According to a publicly disclosed paint spraying device for the production of bucket teeth and bucket tooth seats of excavators (publication number: CN217664075U), in the above application, the paint is transported to the inclined spray head through the suction tube by the suction pump on the right side of the chassis, and then the inclined spray head sprays paint on the bucket teeth or bucket tooth seats adsorbed upward by the magnetic suction device, so that the bottom of the bucket teeth or bucket tooth seats can also be evenly sprayed with paint, and then the entire painting operation is completed. The entire process rotates and rises the paint spraying object, so that the paint spraying device indirectly reaches multiple positions in the three-dimensional space, thereby enhancing its flexibility and coverage.

[0004] However, in actual use, the above equipment rotates and rises the paint object so that the bucket teeth are painted in multiple positions in three-dimensional space, but the surface of the bucket teeth is concave and convex. The bucket teeth simply rotate and rise to receive the paint, and the concave and convex surfaces on the surface are difficult to be evenly covered, which then creates dead angles for painting and reduces the wear resistance of the bucket teeth. In view of this, we propose a painting equipment. Utility Model Content

An arc-shaped frame is provided at the bottom of the telescopic rod. An arc-shaped groove is provided on the inner surface of the arc-shaped frame. The arc-shaped groove provides guidance for the sliding block. The inner surface of the arc-shaped groove is adapted to the outer surface of the sliding block.

[0009] Ball, a ball is provided at the bottom of the sliding block. An annular surface is provided on the lower surface of the sliding block. A U-shaped frame is provided on one side of the sliding block away from the arc-shaped groove. The side wall of the U-shaped frame is fixedly connected to the bottom of the mounting plate through a bracket.

[0010] Preferably, the upper surface of the threaded block fits against the inner surface of the working box. The movable end of the telescopic rod is hinged to the upper surface of the mounting plate. The end of the arc-shaped frame is fixedly connected to the inner wall of the working box.

[0011] Preferably, the bottom of the inner wall of the arc-shaped groove is rotatably connected to the outer surface of the ball. The inner surface of the U-shaped frame is fixedly connected to the outer surface of the liquid pump.

[0012] Preferably, a deflection structure is provided outside the U-shaped frame. The deflection structure includes a groove.

[0015] Compared with the prior art, the present utility model provides a painting device, which has the following beneficial effects:

[0016] 1. In this painting device, through the setting of the painting structure, the motor makes the reciprocating lead screw drive the threaded block to move left and right inside the working box, so that the telescopic rod drives the mounting plate, and then the U-shaped frame drives the sliding block to slide inside the arc-shaped groove, so that the liquid pump moves in a left and right arc shape inside the arc-shaped frame. At the same time, the annular surface of the sliding block cooperates with the ball, so that the liquid pump moves in a wave track. Then, when the liquid spraying head sprays paint on the bucket teeth, it can fit more closely to the convex and concave surfaces of the bucket teeth, avoiding dead angles in painting.

[0017] 2. The paint spraying equipment is provided with a deflection structure. When the sliding block moves inside the arc groove, the repulsive magnetic force between the fixed magnetic block and the movable magnetic block causes the swing plate to drive the rotating shaft to deflect to a certain degree, and the coil spring is stretched accordingly, so that the liquid pump deflects to a certain extent when moving back and forth, thereby improving the uniformity of paint spraying.

[0026] In an embodiment of the present utility model, the upper surface of the threaded block 403 is attached to the inner surface of the working box 1, the movable end of the telescopic rod 404 is hinged to the upper surface of the mounting plate 411, the end of the arc-shaped frame 405 is fixedly connected to the inner wall of the working box 1, the bottom of the inner wall of the arc-shaped groove 406 is rotationally connected to the outer surface of the ball 408, two groups of arc-shaped grooves 406 are provided, and the two groups of arc-shaped grooves 406 are symmetrically arranged with the central axis of the U-shaped frame 410 as the axis of symmetry, a number of groups of balls 408 are provided, and the number of groups of balls 408 are equidistantly distributed inside the two groups of arc-shaped grooves 406, the inner surface of the U-shaped frame 410 is fixedly connected to the outer surface of the liquid pump 2, the input end of the liquid pump 2 is communicated with the inside of a liquid storage tank through a telescopic hose, the liquid storage tank is fixedly connected to one side of the working box 1 close to the motor 401, and a feed port is provided at the top of the liquid storage tank for pouring in painting liquid, the number of sliding blocks 407 provided is the same as that of the arc-shaped grooves 406, and the center point of the arc-shaped frame 405 is higher than the two ends of the arc-shaped frame 405.

[0027] In addition, a deflection structure 5 is arranged outside the U-shaped frame 410, the deflection structure 5 includes a groove 501, the end of a rotating shaft 502 is rotationally connected to the inner surface of the groove 501, the center of a swing plate 503 is fixedly connected to the outer surface of the rotating shaft 502, the fixed end of a torsion spring 504 is fixedly connected to the side wall of the rotating shaft 502, the end of a moving magnet 506 is fixedly connected to the upper surface of the swing plate 503, and a fixed magnet 505 is arranged on the top of the moving magnet 506.

[0028] In an embodiment of the utility model, a groove 501 is provided on the top of the sliding block 407 near the side of the shaped frame 410, and the end of the rotating shaft 502 away from the groove 501 is fixedly connected to the side of the shaped frame 410 away from the liquid pump 2, and the side wall of the fixed magnetic block 505 is fixedly connected to the inner surface of the arc frame 405, and the end of the fixed magnetic block 505 near the moving magnetic block 506 is set at an inclined surface, and the end of the moving magnetic block 506 near the fixed magnetic block 505 is set at an inclined surface, and the magnetic properties of the fixed magnetic block 505 and the moving magnetic block 506 are set with the same polarity, and the fixed end of the coil spring 504 is fixedly connected to the inner wall of the groove 501.

[0029] In the present invention, when in use, multiple groups of bucket teeth are placed in the holder provided inside the working box 1 to position the bucket teeth. At this time, the liquid pump 2 and the motor 401 are turned on. The motor 401 drives the reciprocating screw rod 402 to rotate, so that the reciprocating screw rod 402 drives the threaded block 403 to move left and right inside the working box 1.

At the same time, when the sliding block 407 moves, the movable magnet 506 gradually contacts the fixed magnet 505. The repulsive magnetic force between the two causes the movable magnet 506 to drive the swing plate 503 to move downward, and then the rotating shaft 502 rotates to a certain extent, and the coil spring 504 is stretched accordingly. When the movable magnet 506 follows the sliding block 407 to move away from the fixed magnet 505, the coil spring 504 loses its tension and resets, causing the arc frame 410 to drive the liquid pump 2 to swing slightly, and then the spray head 3 moves left and right in an arc wave trajectory while swinging in a horizontal position to spray the bucket teeth, thereby improving the uniformity of the bucket teeth spraying.
