Description

Technical Field

[0001] This invention relates to the field of polishing and maintenance technology for sports equipment, and more specifically, to a polishing and maintenance device for sports equipment. Background Technology

[0002] With increasing health awareness, the demand for fitness equipment is growing. Dumbbells, as a common piece of fitness equipment, have weight plates whose quality directly affects the user experience and safety. Over time, dumbbell weight plates may develop wear and scratches, affecting not only their appearance but also their lifespan. Therefore, regular polishing and maintenance of dumbbell weight plates is crucial.

In addition, manual operation poses certain safety hazards. Furthermore, since dumbbell weight plates vary in size, the device needs to be adapted to the dumbbell weight plates. To solve these problems, it is particularly necessary to develop a polishing and maintenance device for sports equipment. Summary of the Invention

A slide cylinder 613 is mounted on one end of the inner side of one third connecting shaft 612, and a limiting protrusion 614 is slidably connected to the surface of the slide cylinder 613 on one end of the inner side of the other third connecting shaft 612. A ninth servo motor 616 is mounted on the surface of one movable plate 610, and the output shaft of the ninth servo motor 616 is fixedly connected to a clamping block 615 on one side. A fourth pulley 617 is fixed to the surfaces of the clamping block 615 and the third connecting shaft 612, and the two fourth pulleys 617 are rotatably connected through a fourth transmission belt 618.

[0055] In a specific embodiment of the present invention, when it is necessary to flip the dumbbell weight plate, the seventh electric cylinder 608 is activated. The piston rod of the seventh electric cylinder 608 drives the eighth moving seat 607 to move on the surface of the sixth guide rail 606. At the same time, the ninth servo motor 616 starts its output shaft to drive a clamping block 615 to rotate. At this time, under the action of the fourth pulley 617 and the fourth transmission belt 618, the third connecting shaft 612 on one side is driven to rotate. At the same time, under the action of the slide cylinder 613 and the limiting protrusion 614, the other third connecting shaft 612 is driven to rotate. At this time, under the action of the fourth pulley 617 and the fourth transmission belt 618 on the other side, the third connecting shaft 612 on the other side is driven to rotate, thereby flipping the dumbbell weight plate.

[0056] A method for using a polishing and maintenance device for sports equipment includes the following steps:

[0057] The dumbbell weights can be conveyed by the feeding conveyor belt 2. By adjusting the positions of the two second mounting seats 302 on the surfaces of the two first mounting seats 301 and limiting the second mounting seats 302 by the connecting bolts 303, the dumbbell weights can be guided by the first guide plate 304. During conveying, the first servo motor 307 is started, and its piston rod drives a first rotating shaft 305 to rotate under the action of the first pulley 308 and the first transmission belt 309. At the same time, the transmission belt 306 drives another first rotating shaft 305 to rotate and convey the dumbbell weights.

[0058] The second servo motor 404 starts its output shaft, driving the first threaded rod 405 to rotate, thereby causing the first moving seat 403 to move under the action of the first guide rail 402. The fourth servo motor 414 starts its output shaft, driving one of the first rotating wheels 415 to rotate. At this time, under the action of the first polishing belt 416, multiple first rotating wheels 415 rotate. The dumbbell counterweight applies force to two of the first rotating wheels 415, compresses the two rotating parts 412, and charges the spring telescopic rod 413. At the same time, the first electric cylinder 417 starts its piston rod, driving the second rotating wheel 418 to move. Simultaneously, the third servo motor 411 starts its output shaft, driving the elliptical roller 410 to rotate. At this time, under the action of the rotating roller 409, the first... The second moving seat 408 reciprocates longitudinally. At this time, under the action of the first rotating wheel 415, the first polishing belt 416 and the second rotating wheel 418, the side of the dumbbell weight plate is polished from one side. At the same time, the third electric cylinder 424 starts its piston rod to drive the third moving seat 423 to move on the surface of the third guide rail 422. The fifth servo motor 430 starts its output shaft to drive the fifth rotating wheel 431 to rotate. At this time, under the action of the second polishing belt 432, the fourth rotating wheel 429 and the sixth rotating wheel 433 are driven to rotate. At the same time, the fourth electric cylinder 427 starts its piston rod to drive the fourth moving seat 428 to move on the surface of the fourth guide rail 426, thereby driving the second polishing belt 432 to come into contact with the other side of the dumbbell weight plate and polish it.

[0059] Subsequently, the output shaft of the sixth servo motor 506 is started, and under the action of the second pulley 507 and the second transmission belt 508, it drives the second threaded rod 502 to rotate. The rotation of the second threaded rod 502 drives the fifth moving seat 503 to move, and the fifth moving seat 503 moves on the surface of the fifth guide rail 505. The electric slide table 504 starts its moving parts to drive the sixth moving seat 509 to move. The movement of the sixth moving seat 509 drives the fifth electric cylinder 510 to move. At this time, the fifth electric cylinder 510 and the electric gripper 511 are started, which can drive the dumbbell counterweight to move to the surface of the polishing base 604.

[0060] At this time, the moving part of the electric slide table 504 drives the polishing wheel 517 to move above the dumbbell weight plate. Then, the sixth electric cylinder 512 starts its piston rod to drive the polishing wheel 517 to fit with the dumbbell weight plate. At the same time, the seventh servo motor 518 starts its output shaft, which, under the action of the third pulley 519 and the third transmission belt 520, drives the second rotating shaft 516 and the polishing wheel 517 to polish the upper surface of the dumbbell weight plate. The eighth servo motor 603 starts its output shaft to drive the polishing base 604 and the dumbbell weight plate to rotate. At the same time, the eighth electric cylinder 611 starts to drive the two moving plates 610 to move on the surface of the seventh guide rail 609, thereby driving the clamping block 615 to limit the dumbbell weight plate. At this time, the polishing wheel 517 can be used to polish the dumbbell weight plate.

[0061] When the dumbbell weight plate needs to be flipped, the seventh electric cylinder 608 is activated. The piston rod of the seventh electric cylinder 608 drives the eighth moving seat 607 to move on the surface of the sixth guide rail 606. At the same time, the ninth servo motor 616 starts its output shaft to drive a clamping block 615 to rotate. At this time, under the action of the fourth pulley 617 and the fourth transmission belt 618, the third connecting shaft 612 on one side is driven to rotate. At the same time, under the action of the slide cylinder 613 and the limiting protrusion 614, the other third connecting shaft 612 is driven to rotate. At this time, under the action of the fourth pulley 617 and the fourth transmission belt 618 on the other side, the third connecting shaft 612 on the other side is driven to rotate, thereby flipping the dumbbell weight plate. After flipping, the dumbbell weight plate is polished and maintained again by the polishing wheel 517.

[0062] After polishing and curing, the dumbbell counterweight plate is moved to the surface of the unloading conveyor belt 7 by the functional mechanism 5. At this time, the unloading conveyor belt 7 unloads the polished dumbbell counterweight plate.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
