Description

Technical Field

[0001] The invention relates to the technical field of metal plating, in particular to surface galvanizing treatment equipment for metal dumbbell production. Background Art

[0002] Dumbbells, also known as dumbbells in English, are an auxiliary equipment for weightlifting and fitness exercises. They are smaller than barbells. Light dumbbells weigh 1, 2, 3, 5, 8, 12 pounds (1 pound = 0.4536 kilograms), etc. Heavy dumbbells weigh 10, 15, 30 kilograms, etc. Because they are silent during exercise, they are named dumbbells. Dumbbells are usually multi-piece and metal-integrated. As metal dumbbells, in order to improve the surface finish and corrosion resistance of the dumbbells, a layer of zinc coating needs to be attached to the surface of the dumbbells.

[0003] According to the authorization announcement number: CN 114959535 B, a pipe galvanizing device and process disclosed includes a pipe galvanizing device, including a horizontal track, a horizontal slide 1 and a horizontal slide 2, both of which are horizontally slidably arranged on the horizontal track, a vertical track 1 and a vertical track 2, respectively arranged on the horizontal slide 1 and the horizontal slide 2, a vertical slide 1 and a vertical slide 2, respectively slidably arranged on the vertical track 1 and the vertical track 2, a first traction rope, a second traction rope, the lower end of the first traction rope is connected to the vertical slide 1 to drive it to rise and fall, and the lower end of the second traction rope is connected to the vertical slide 2 to drive it to rise and fall, a galvanizing pool 1, a processing pool, and a galvanizing pool 2, wherein the horizontal slide 1 and the horizontal slide 2 have a hanging position 1, a galvanizing position 1, a processing position, a galvanizing position 2, and a hanging position 2. Through the above technical solution, the technical problems of low galvanizing efficiency, time-consuming, labor-intensive and unsafe galvanizing in the related art are solved, but the above existing galvanizing device is found after use:

[0004] The above-mentioned existing galvanizing devices cannot achieve the technical effect of automatic pre-cleaning of materials, so that the dust attached to the surface of the material is extremely easy to enter the galvanizing along with the material, resulting in sand problems on the surface of the material after galvanizing, and affecting the adsorption strength of the galvanized layer. At the same time, the above-mentioned existing galvanizing devices cannot remove excess galvanizing liquid on the surface of the material. When the material is lifted out of the galvanizing pool, the excess galvanizing liquid on the surface of the material is lifted up and directly participates in the subsequent drying, which will cause a large amount of galvanizing liquid to be wasted, which is not conducive to the control of production costs.

The fixed block 401 is rotatably connected to an air shower shaft 402 inside, and one end of the air shower shaft 402 is fixedly connected to an air shower blade 403, and one end of the air shower shaft 402 away from the air shower blade 403 is fixedly connected to a passive bevel gear 404, and the side wall of the passive bevel gear 404 is meshed with an active bevel gear 405, and the inner wall of the active bevel gear 405 is fixedly connected to a power rod 406, and the fixed The left side of the block 401 is fixedly connected to two first bearing seats 407 distributed front and back, and the two first bearing seats 407 are rotatably connected to the outer wall of the power rod 406 through bearings. A passive pulley 408 is fixedly connected to the outer wall of the power rod 406, and the passive pulley 408 is located between the two first bearing seats 407.

[0046] Specifically, when the torsion bolt rod 201 rotates, it will drive the active pulley 4010 to rotate synchronously, and under the connection of the power belt 409 and the passive pulley 408, it will drive the power rod 406 to rotate, and further drive the air shower shaft 402 to rotate under the meshing of the active bevel gear 405 and the passive bevel gear 404, and further rotate the air shower fan blade 403 to blow the surface of the dumbbell, and blow the dust attached to the dumbbell out through the dust outlet 102, thereby ensuring the neatness of the dumbbell before galvanizing, avoiding the dumbbell surface from participating in galvanizing with dust, and improving the quality of galvanizing of the dumbbell and the strength effect after galvanizing.

[0047] In this embodiment, refer to Figure 5 , Figure 6 As shown, the adjustment mechanism 5 includes an adjustment frame 501, which is fixedly connected between the left wall and the right wall of the circular guide rail 3013.

[0048] Specifically, by rotating the adjustment rod 506, the two worm gears 505 are driven to rotate, thereby causing the two worm wheels 504 meshing with the two worm gears 505 to rotate, further driving the two forward and reverse lead screws 503 to rotate. Since the forward and reverse lead screws 503 are reverse threads symmetrically distributed in the middle, the front and rear adjustment frames 501 move toward the middle along the guide holes 509. When the adjustment frame 501 moves, it will drive the return guide rail 3013 to move synchronously. When the two return guide rails 3013 move toward the middle, the inner side of the return guide rail 3013 will push the I-shaped wheel 306 inward, further causing the sliding rod 304 and the tensioning support 307 to move toward the middle.

[0050] Specifically, by opening the ash outlet 102 at the right end of the air shower mechanism 4, the dust blown by the air shower mechanism 4 can be bulged to the outside through the ash outlet 102 to prevent the dust from staying in the galvanizing box 1. When the wandering gear 3012 moves with the I-shaped wheel 306 and meshes with the first tooth block 6, it will rotate along the first tooth block 6, further driving the clamped dumbbell to rotate synchronously. By setting the dumbbell to rotate, the dumbbell can be blown 360° to avoid the occurrence of blowing dead corners and ensure the effect of blowing on the dumbbell. Then the dumbbell continues to move downward and is immersed in the galvanizing liquid inside the galvanizing box 1 to be galvanized. When the dumbbell moves to the lowest point, along with the operation mechanism 2 During the operation, the galvanized dumbbell is lifted up. During the operation, the wandering gear 3012 will mesh with the second tooth block 7, causing the dumbbell to rotate again. The rotating dumbbell will generate centrifugal force to shake off the excess galvanizing liquid on the surface of the dumbbell. The galvanizing liquid that is thrown out will flow back to the inside of the galvanizing box 1 under the gravity of the liquid baffle 9, thereby avoiding the waste of the galvanizing liquid. The dumbbell is then baked through multiple heating tubes 8, and at this time the wandering gear 3012 is still meshed with the second tooth block 7, so the dumbbell continues to rotate, so that the heating tube 8 can bake the dumbbell 360°, ensuring the uniformity of the galvanizing baking of the dumbbell, until the galvanizing liquid on the surface of the dumbbell is dried, and the dumbbell is just moved to the height of the discharge port 103.

[0052] Specifically, a plurality of dumbbells to be galvanized are supported on the top of two inclined guide blocks 12, and the dumbbells will roll to the right along the top inclined surface of the inclined guide blocks 12 until they are stopped by two limit columns 13, and then they are clamped and carried away in sequence by the operating clamping mechanism 3, thereby realizing automatic loading in a flow-type manner and improving the efficiency of galvanizing.

[0053] In this embodiment, refer to Figure 2 , Fig.12 As shown, a discharge port 103 is provided through the left side of the galvanizing box 1, and the discharge port 103 is located at the bottom of the loading port 101.

The tops of the material guide racks 15 are provided with strip-shaped slots 16. A positioning pin 17 is fixedly connected between the front wall and the rear wall of the galvanizing box 1. The positioning pin 17 is located at the right end of the material guide rack 15. Two material receiving rods 18 are rotatably connected to the outer wall of the positioning pin 17. The two material receiving rods 18 are located at the right ends of the two material guide racks 15. The bottoms of the two material receiving rods 18 are fixedly connected to support racks 19, and the ends of the support racks 19 are grounded to the right side of the material guide racks 15.

[0054] Specifically, when the dumbbell is lifted up to the position of the discharge port 103, it will contact the bottom of the two receiving rods 18 and push the receiving rods 18 upward, so that the two receiving rods 18 flip upward along the positioning pin rods 17, thereby not interfering with the dumbbell's continued upward movement. When the dumbbell continues to move upward, the dumbbell will gradually move away from the bottom of the two receiving rods 18. The bottoms of the two receiving rods 18 lose thrust and rotate downward until the two supporting frames 19 abut against the right side of the guide frame 15 to support the two receiving rods 18, thereby preventing the two When the receiving rod 18 rotates excessively to the right and the clamping mechanism 3 holding the dumbbell moves to the release groove 3014, the spring 309 rebounds and pulls the tensioning support 307 to open, thereby releasing the clamping of the dumbbell. At this time, the dumbbell freely moves downward to the top of the two receiving rods 18 under the force of gravity, and then rolls along the top of the two receiving rods 18 to the top of the guide frame 15 and falls into the strip groove 16 and is limited to prevent the dumbbell from falling off and hitting the ground. Then the worker can directly remove it from the strip groove 16.

[0055] In this embodiment, refer to Fig.10 As shown, two key grooves 3010 are provided on the inner wall of the sliding tube 303, and the two key grooves 3010 are symmetrically distributed through the center of the sliding tube 303, and the insides of the two key grooves 3010 are slidably connected with splines 3011, and the two splines 3011 are fixedly connected to the outer wall of the sliding rod 304;

[0056] Specifically, by setting the keyway 3010 and the spline 3011 for sliding connection, the sliding effect between the sliding rod 304 and the sliding tube 303 can be ensured, while the mutual torque limiting effect can be achieved, thereby ensuring the torsional force transmission effect of the wandering gear 3012 on the tensioning support 307.

[0057] In this embodiment, refer to Figure 6 As shown, two guide rods 508 distributed on the left and right are formed through the front side of the adjustment frame 501. The two guide rods 508 are located on both sides of the threaded hole 502. A guide hole 509 is slidably inserted inside the guide rod 508. The guide hole 509 is fixedly connected between the front wall and the rear wall of the galvanizing box 1.

[0058] Specifically, by setting a sliding connection between the guide rod 508 and the guide hole 509, the adjustment frame 501 is guided to ensure the stability of the movement of the adjustment frame 501. The adjustment frame 501 further limits the circular guide rail 3013 and further adjusts the circular guide rail 3013.

[0059] When the surface galvanizing treatment equipment for producing metal dumbbells in this scheme is working, the clamping distance of the clamping mechanism 3 is first adjusted according to the length of the dumbbell to be galvanized, and the two worms 505 are driven to rotate by rotating the adjusting rod 506, so that the two worm wheels 504 meshing with the two worms 505 rotate, and further drive the two positive and negative lead screws 503 to rotate. Since the positive and negative lead screws 503 are reverse threads symmetrically distributed in the middle, the front and rear adjustment frames 501 move toward the middle along the guide holes 509. When the adjustment frames 501 move, the return guide rails 3013 will be driven to move synchronously. When the two return guide rails 3013 move toward the middle, the inner side of the return guide rails 3013 will push the I-shaped wheel 306 inward, further causing the sliding rod 304 and the tensioning support 307 to move toward the middle. At the same time, the spring 309 is stretched to generate elastic storage force, so that the distance between the two tensioning supports 307 is adapted to the length of the dumbbell.

[0060] A plurality of dumbbells to be galvanized are mounted on the top of the two inclined guide blocks 12, and the dumbbells will roll to the right along the top inclined surface of the inclined guide blocks 12 until they are stopped by the two limit posts 13. During this period, the AC motor 204 drives the torsion bolt rod 201 to rotate, and further the sprocket 202 fixedly connected to the torsion bolt rod 201 rotates synchronously. Further, under the connection between the chain 203 and the other sprocket 202, the overall operation of the operating mechanism 2 is realized, and the clamping mechanism 3 is further driven to rotate. During the rotation of the clamping mechanism 3, the I-shaped wheel 306 When the clamping mechanism 3 rotates to the release groove 3014, it is released by the elasticity of the spring 309, pushing the sliding rod 304 and the tensioning support 307 to move to both sides, and the front and rear tensioning supports 307 open. As the operating mechanism 2 continues to rotate, when the work-shaped wheel 306 rolls away from the release groove 3014, the two work-shaped wheels 306 are guided by the inner wall of the return guide rail 3013 and shrink toward the middle again, driving the two tensioning supports 307 to move toward the middle, just to be The dumbbells held by the two limit columns 13 are clamped front and back and rotated with the dumbbells. The remaining dumbbells continue to roll on the top of the two inclined guide blocks 12 and are clamped and carried by the next clamping mechanism 3, thereby realizing automated water-flow feeding. When the dumbbells clamped by the clamping mechanism 3 move to the right end of the air shower mechanism 4, the wandering gear 3012 on the clamping mechanism 3 just meshes with the first tooth block 6, so that the wandering gear 3012 rotates to drive the sliding pipe 303 to rotate, further making the sliding rod 304 and the tensioning support 307 The active pulley 4010 rotates, further driving the clamped dumbbell to rotate, and during this period, the active pulley 4010 rotates along with the torsion bolt rod 201, driving the power rod 406 to rotate under the connection of the power belt 409 and the passive pulley 408, and further driving the air shower shaft 402 to rotate under the meshing of the active bevel gear 405 and the passive bevel gear 404, and further causing the air shower blade 403 to rotate, blowing the rotating dumbbell, and blowing the dust attached to the dumbbell out through the dust outlet 102, ensuring the neatness of the dumbbell before galvanizing;

[0061] Then the dumbbell continues to move downward and is immersed in the galvanizing liquid inside the galvanizing box 1. The dumbbell is galvanized by the action of electrodes (this electroplating method is a prior art means and will not be described in detail here). When the dumbbell moves to the lowest point, the galvanized dumbbell is lifted up with the operation of the operating mechanism 2. During this period, the wandering gear 3012 will mesh with the second tooth block 7, causing the dumbbell to rotate again. The rotating dumbbell will generate centrifugal force, which can throw away the excess galvanizing liquid on the surface of the dumbbell. The thrown galvanizing liquid flows back to the inside of the galvanizing box 1 under the gravity of the liquid baffle 9, thereby avoiding the waste of the galvanizing liquid. Then the dumbbell is baked through multiple heating tubes 8, and at this time the wandering gear 3012 is still meshed with the second tooth block 7, so the dumbbell continues to rotate, so that the heating tube 8 can bake the dumbbell 360°, ensuring the uniformity of the galvanizing baking of the dumbbell, until the galvanizing liquid on the surface of the dumbbell is dried, and at this time the dumbbell just moves to the height of the discharge port 103;

[0062] When the dumbbell is lifted up to the position of the discharge port 103, it will contact the bottom of the two receiving rods 18 and push the receiving rods 18 upward, so that the two receiving rods 18 are flipped upward along the positioning pin rods 17, thereby not interfering with the dumbbell's continued upward movement. When the dumbbell continues to move upward, the dumbbell will gradually move away from the bottom of the two receiving rods 18. The bottoms of the two receiving rods 18 lose thrust and rotate downward until the two supporting frames 19 abut against the right side of the guide frame 15, supporting the two receiving rods 18 to prevent the two receiving rods 18 from rotating too far to the right. Then, when the clamping mechanism 3 clamping the dumbbell moves to the release groove 3014 position, the spring 309 rebounds and pulls the tensioning support 307 to open, thereby releasing the clamping of the dumbbell. At this time, the dumbbell is freely naked downward to the top of the two receiving rods 18 under gravity, and then rolls along the top of the two receiving rods 18 to the top of the guide frame 15 and falls into the strip groove 16 and is limited.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
