Description
Technical Field
[0001] The utility model relates to a spraying device, in particular to a NdFeB permanent magnet material spraying device. Background Art
[0002] NdFeB is a magnet that contains a large amount of rare earth elements neodymium, as well as iron and boron. It is hard and brittle. As a rare earth permanent magnet material, NdFeB has extremely high magnetic energy product and coercive force. At the same time, the advantage of high energy density makes NdFeB permanent magnet materials widely used in modern industry and electronic technology. Because the surface is easily oxidized and corroded, NdFeB permanent magnet materials must be treated with surface coating. Currently, NdFeB permanent magnet materials are generally sprayed in batches by roller spraying machines. However, when spraying flat, strip-shaped and other strong magnetic materials, the material is not easy to fully flip as the roller of the sprayer rotates, resulting in the presence of unsprayed surfaces during spraying, affecting the spraying quality.

[0013] (III) Beneficial effects
[0014] The utility model provides a NdFeB permanent magnet material spraying device, which has the following beneficial effects:
[0015] 1.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The utility model provides a NdFeB permanent magnet material spraying device, such as Figure 1-5 As shown, it includes a chassis 1 and a roller 2 rotatably installed therein, a shielding cover that can shield the opening of the roller 2 is installed on the front surface of the chassis 1, a tank body for storing paint is installed in the chassis 1, and the end of the material pipe of the tank body extends to the shielding cover and faces the inside of the roller 2, a motor driving the roller 2 to rotate is installed in the chassis 1, and a PLC controller for controlling the motor and the material pipe is installed on the side wall of the chassis 1. During spraying, the motor drives the roller 2 to rotate so that the material inside it is constantly turned over, and the end of the material pipe sprays paint to the piled material as much as possible to perform the spraying operation, and a turning piece 4 that can turn over the internal neodymium iron boron permanent magnet material is installed on the side wall of the roller 2 and away from the opening, and an upper push block 5 and a lower push block 6 that can squeeze the turning piece 4 to make it move are installed in the chassis 1;
[0025] The flipping member 4 includes a slide bar 41 that passes through the side wall of the drum 2 and is in sliding contact with the same. One end of the slide bar 41 located inside the drum 2 is movably connected to a flippable push plate 42. The flipping angle of the push plate 42 is forty-five degrees, that is, the push plate 42 can be flipped forty-five degrees from a state parallel to the inner wall of the drum 2 toward the opening of the drum 2. At this time, the bottom of the push plate 42 abuts against the top of the slide bar 41 and cannot be flipped anymore, so that the material away from the opening of the drum 2 can be flipped toward the opening side of the drum 2. The other end of the slide bar 41 is connected to an arc block 43 that can contact the upper push block 5 and the lower push block 6 when the drum 2 rotates. The upper push block 5 is located directly below the drum 2, and the lower push block 6 is located above the drum 2. When the roller 2 just hits the upper push block 5 as it rotates, the NdFeB permanent magnet material accumulates on the top of the push plate 42. As the roller 2 rotates and the upper push block 5 squeezes the flipping member 4, the slide bar 41 moves into the roller 2, and the push plate 42 moves up accordingly and cuts the material piled close to the roller 2 at the bottom side, pushing it toward the opening side of the roller 2. Since there is a gap between the push plate 42 and the roller 2 when it moves up, the material close to the opening side of the roller 2 will slide down and move to the inside of the roller 2, realizing full flipping of the material (the flipping direction is parallel to the axis of the roller 2), avoiding the problem that the flat material, which is not easy to flip, is not easy to flip fully in the roller 2 when the roller 2 rotates, thereby affecting the spraying efficiency.
[0026] Specifically, the side walls of the arc block 43, the upper push block 5 and the lower push block 6 are all fixed with sleeves 44, and the side walls of the sleeves 44 are penetrated by screws threadedly connected thereto, one end of the slide rod 41 is inserted into the sleeve 44 of the side wall of the arc block 43 and fixed with screws, and the sleeves 44 of the side walls of the upper push block 5 and the lower push block 6 are inserted with fixing rods 7 and fixed with screws, and the ends of the fixing rods 7 are connected to the inner wall of the chassis 1, and the arc block 43, the upper push block 5 and the lower push block 6 are all connected with the slide rod 41 and the fixing rod 7 by sleeves 44, which is convenient for loading and unloading, and is convenient for replacing and maintaining the arc block 43, the upper push block 5 and the lower push block 6 that are in sliding contact with each other and are easily worn, thereby ensuring the flipping effect of the equipment on the neodymium iron boron permanent magnet material.
[0027] Specifically, a groove 8 adapted to the push plate 42 is provided inside the drum 2. The groove 8 facilitates the side wall of the push plate 42 to be flush with the inner wall of the drum 2, so that the material can slide onto it for turning.
[0028] Specifically, a spring 10 is sleeved on the outer wall of the slide rod 41 and located outside the drum 2. The spring 10 tends to keep the arc block 43 away from the drum 2, so that the push plate 42 is close to the inner wall of the drum 2, avoiding a gap between the push plate 42 and the drum 2 before the push plate 42 contacts the material to flip it, thereby affecting the flipping effect.
[0029] Specifically, an arc groove 9 is provided on one side of the push plate 42 away from the slide rod 41, which can increase the surface area of the push plate 42 and facilitate turning more NdFeB permanent magnet materials at a time.
[0030] Specifically, the inner wall side of the drum 2 is fixed with ribs 3 parallel to its axis, which can flip the NdFeB permanent magnet material perpendicular to its axis when the drum 2 rotates, that is, the material on the bottom side of the material pile is flipped to the top side.
[0031] Working principle: During spraying, the motor drives the drum 2 to rotate, so that the material inside it is constantly turned over, and the end of the material tube sprays paint toward the piled material as much as possible to carry out the spraying operation. When the turning part 4 rotates with the drum 2 and just touches the upper push block 5, the neodymium iron boron permanent magnet material accumulates on the top of the push plate 42. As the drum 2 rotates and the upper push block 5 squeezes the turning part 4, the slide bar 41 moves into the drum 2, and the push plate 42 moves up accordingly and cuts the bottom side of the material pile close to the material in the drum 2, and pushes it toward the opening side of the drum 2. Since there is a gap between the push plate 42 and the drum 2 when it moves up, the material close to the opening side of the drum 2 will slide down to the inside of the drum 2, realizing full turning of the material (the turning direction is parallel to the axis of the drum 2), avoiding the problem that flat materials that are not easy to turn over are not easy to fully turn over in the drum 2 when the drum 2 rotates, thereby affecting the spraying efficiency.
