A plurality of dumbbell racks to be galvanized are held at the tops of two inclined guide blocks 12, the dumbbell rolls rightward along the inclined surfaces of the tops of the inclined guide blocks 12 until the dumbbell is stopped after being limited by two limiting posts 13, an alternating current motor 204 drives a torsion bolt rod 201 to rotate, a chain wheel 202 fixedly connected with the torsion bolt rod 201 further rotates synchronously, the whole operation of an operating mechanism 2 is further realized under the connection of a chain 203 and another chain wheel 202, a clamping mechanism 3 is further driven to rotate, an I-shaped wheel 306 rolls along the inner wall of a circular guide rail 3013 during the rotation of the clamping mechanism 3, when the clamping mechanism 3 rotates to a position of a release groove 3014, the elastic release of a spring 309 pushes a sliding connection rod 304 and a tensioning support 307 to move to two sides, the front tensioning support 307 and the rear tensioning support 307 are opened, and as the operating mechanism 2 continues to rotate, and when the I-shaped wheel 306 rolls away from the release groove 3014, the two I-shaped wheels 306 are guided by the inner wall of the return guide rail 3013 to shrink towards the middle again to drive the two tensioning brackets 307 to move towards the middle, just clamps the dumbbell limited by the two limiting posts 13 back and forth and carries the dumbbell to rotate along with the dumbbell, the rest dumbbell continues rolling at the tops of the two inclined guide blocks 12 and is clamped and carried by the next clamping mechanism 3, so that automatic running water feeding is realized, when the dumbbell clamped by the clamping mechanism 3 moves to the right end of the air shower mechanism 4, the travelling gear 3012 on the clamping mechanism 3 is just meshed with the first tooth block 6, so that the travelling gear 3012 rotates to drive the sliding connection pipe 303 to rotate, further the sliding connection rod 304 and the tensioning brackets 307 rotate to further drive the clamped dumbbell to rotate, the driving pulley 4010 rotates along with the torsion bolt 201 during the period, the power rod 406 is driven to rotate under the connection effect of the power belt 409 and the driven pulley 408, further, the air shower shaft 402 is driven to rotate under the meshing of the driving bevel gear 405 and the driven bevel gear 404, so that the air shower fan blades 403 are further rotated to blow the rotating dumbbell, dust attached to the dumbbell is blown out through the ash outlet 102, and the clean effect of the dumbbell before galvanization is ensured;
then the dumbbell continues to move downwards, infiltrate into the galvanizing liquid in the galvanizing box 1, under the action of the electrode (the electroplating mode is the prior art means, and is not specifically described herein), the dumbbell is galvanized, after the dumbbell moves to the lowest point, the galvanized dumbbell is lifted upwards along with the operation of the operation mechanism 2, during the period, the wandering gear 3012 is meshed with the second tooth block 7, the dumbbell is rotated again, centrifugal force is generated by the rotating dumbbell, the superfluous galvanizing liquid on the surface of the dumbbell can be thrown away, the thrown galvanizing liquid flows back into the galvanizing box 1 under the gravity of the liquid baffle 9, so that the waste of the galvanizing liquid is avoided, then the dumbbell is baked through the plurality of heating pipes 8, and at the moment, the wandering gear 3012 is meshed with the second tooth block 7, so that the heating pipes 8 can bake the dumbbell at 360 degrees, the uniformity of the galvanizing baking of the dumbbell is ensured until the dumbbell is just moved to the height of the discharging port 103;
when the dumbbell lifts up to the position of the discharge hole 103, the dumbbell contacts with the bottoms of the two receiving rods 18 and pushes the receiving rods 18 upwards, so that the two receiving rods 18 turn upwards along the positioning pin rods 17, the dumbbell is not interfered to continue to move upwards, when the dumbbell continues to move upwards, the dumbbell gradually moves away from the bottoms of the two receiving rods 18, the bottoms of the two receiving rods 18 lose thrust and then turn downwards until the two support frames 19 are abutted against the right side surface of the material guide frame 15, the two receiving rods 18 are supported, the two receiving rods 18 are prevented from turning rightwards excessively, when the clamping mechanism 3 for clamping the dumbbell moves to the position of the release groove 3014, the spring 309 springs and pulls the tensioning support 307 to open, so that the clamping of the dumbbell is released, at the moment, the dumbbell falls into the bar-shaped notch 16 after freely bare bodies downwards by gravity to the tops of the two receiving rods 18, and then rolls to the tops of the material guide frame 15 along the tops of the two receiving rods 18.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
