[0002] Kettlebells, as a common fitness tool, require shaping and polishing during production to ensure precise shape and a smooth surface. Traditional kettlebell polishing relies heavily on manual operation, which suffers from uneven polishing and low efficiency. Furthermore, manual operation demands high levels of worker skill and is prone to errors during production. With increasing production demands and technological advancements, automated polishing devices have emerged. These devices precisely control polishing force and angle through mechanization and automation, improving production efficiency and product quality, reducing labor costs, and promoting the modernization of kettlebell manufacturing processes.

[0003] Chinese patent CN114193272B discloses a kettlebell forming and grinding device for fitness and body shaping, including a base plate, auxiliary device, limiting device, and grinding device. This patent solves the main problems in the current kettlebell outer wall grinding process, such as the difficulty of the grinding wheel adhering to the kettlebell outer wall, which affects the processing effect of the kettlebell outer wall, and the difficulty of maintaining stability during the kettlebell fixing process due to its special structure. The wobbling kettlebell can easily affect the processing effect of the kettlebell outer wall during the grinding process. This patent improves the processing effect of the kettlebell outer wall and ensures the stability of the kettlebell during the processing.

[0004] However, the current device has the following problems: the debris cannot be effectively collected and enters the moving parts of the equipment, causing parts to jam, clog or wear excessively, reducing the service life of the equipment and increasing maintenance costs, causing the machine to run poorly, increasing cleaning and maintenance time, reducing production efficiency, interfering with the operator's monitoring of the production status, and prolonging downtime and maintenance time. Therefore, we propose a molding and grinding device for kettlebell production. Utility Model Content

[0005] The purpose of this invention is to provide a molding and grinding device for kettlebell production, which can solve the problems in related technologies where debris cannot be effectively collected and enters the moving parts of the equipment, causing parts to jam, clog, or wear excessively, reducing the service life of the equipment and increasing maintenance costs, resulting in machine malfunction, increased cleaning and maintenance time, reduced production efficiency, interference with operators' monitoring of production status, and extended downtime and maintenance time.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A molding and polishing device for kettlebell production includes a molding body, an electric telescopic rod fixedly connected to the top of the molding body, a polishing disc fixedly connected to the telescopic end of the electric telescopic rod, a movable lead screw rotatably connected to the inner wall of the molding body, the movable lead screw being driven by a motor and fixedly connected to the side of the molding body, a lead screw sleeve threadedly connected to the outer wall of the movable lead screw, an L-shaped fixing plate fixedly connected to the top of the lead screw sleeve, a limit buckle fixedly connected to the bottom of the L-shaped fixing plate, a fixing platform fixedly connected to the top of the lead screw sleeve, and a kettlebell mounted on the top of the fixing platform.

[0008] A collecting device is provided on the top of the molding body. The collecting device includes a support plate, the bottom of which is fixedly connected to the top of the molding body. A V-shaped collecting groove is fixedly connected to the top of the support plate. A placement plate is fixedly connected to the top of the molding body. A drive motor is fixedly connected to the side of the placement plate. A rotating shaft is fixedly connected to the output shaft of the drive motor. Multiple rotating columns are fixedly connected to the circumferential surface of the rotating shaft. A fixing rod is fixedly connected to the inclined surface of the V-shaped collecting groove. A baffle is fixedly connected to the bottom of the fixing rod. A sliding plate is slidably connected to the circumferential surface of the fixing rod. A striking plate is fixedly connected to the top of the sliding plate. A spring is provided between the V-shaped collecting groove and the sliding plate.

[0009] The V-shaped collection groove is in contact with the fixed platform and the grinding disc. The V-shaped collection groove is located on the displacement trajectory of the striking plate.

[0010] A protrusion is fixedly connected to the end of the rotating column away from the rotating axis, and a protrusion is fixedly connected to the top edge of the sliding plate. The circular surface of the protrusion of the sliding plate is located on the movement trajectory of the circular surface of the protrusion of the rotating column.

[0011] The output shaft of the drive motor is equipped with a dispersing device, which includes a threaded rod fixedly connected to the output shaft of the drive motor. A threaded sleeve is threadedly connected to the outer wall of the threaded rod. A limit rod is fixedly connected to the inner wall of the V-shaped collecting groove. A movable plate is fixedly connected to the circumferential surface of the threaded sleeve. A V-shaped push plate is fixedly connected to the bottom of the movable plate.

[0012] The lead screw sleeve contacts the molding body, and the limiting buckle contacts the kettlebell.

[0013] The threaded sleeve contacts the limiting rod, and the V-shaped push plate contacts the V-shaped collecting groove.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention, through the design of a collection device, coordinates the V-shaped collection trough, drive motor, rotating shaft, rotating column, sliding plate, striking plate, and spring. The sliding plate resets under the corresponding spring force, and the sliding plate drives the striking plate to reset and move upward to strike the V-shaped collection trough. This prevents debris from entering the moving parts of the equipment, thus preventing wear or jamming, thereby reducing the frequency of equipment failures and maintenance costs, extending the service life of the equipment, reducing workshop pollution, and reducing the cost of regular cleaning and maintenance. It also avoids the long-term accumulation of debris in the equipment and workshop, which brings cleaning difficulties and time costs.

[0016] This invention utilizes a dispersing device to coordinate the threaded rod, threaded sleeve, moving plate, and V-shaped push plate. The movement of the threaded sleeve drives the movement of the moving plate, which in turn drives the movement of the V-shaped push plate. The movement of the V-shaped push plate disperses the debris in the V-shaped collection trough, preventing debris accumulation and keeping the collection trough unobstructed. This ensures that the working area remains clean and unobstructed, thereby improving the overall efficiency of the production line, maintaining a clean working environment, reducing the risk of accidents, and distributing debris more evenly, facilitating subsequent cleaning, sorting, and recycling.

Detailed Implementation

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-5 As shown, a molding and grinding device for kettlebell production includes a molding body 1, an electric telescopic rod 2 fixedly connected to the top of the molding body 1, a grinding disc 3 fixedly connected to the telescopic end of the electric telescopic rod 2, a movable lead screw 6 rotatably connected to the inner wall of the molding body 1, the movable lead screw 6 being driven by a motor and the motor being fixedly connected to the side of the molding body 1, a lead screw sleeve 7 threadedly connected to the outer wall of the movable lead screw 6, an L-shaped fixing plate 8 fixedly connected to the top of the lead screw sleeve 7, a limit buckle 9 fixedly connected to the bottom of the L-shaped fixing plate 8, a fixing platform 10 fixedly connected to the top of the lead screw sleeve 7, and a kettlebell 11 disposed on the top of the fixing platform 10;

[0026] A collecting device 4 is provided on the top of the molding body 1. The collecting device 4 includes a support plate 41. The bottom of the support plate 41 is fixedly connected to the top of the molding body 1. A V-shaped collecting groove 42 is fixedly connected to the top of the support plate 41. A placement plate 43 is fixedly connected to the top of the molding body 1. A drive motor 44 is fixedly connected to the side of the placement plate 43. A rotating shaft 45 is fixedly connected to the output shaft of the drive motor 44. Multiple rotating columns 46 are fixedly connected to the circumferential surface of the rotating shaft 45. A fixing rod 47 is fixedly connected to the inclined surface of the V-shaped collecting groove 42. A baffle 48 is fixedly connected to the bottom of the fixing rod 47. A sliding plate 49 is slidably connected to the circumferential surface of the fixing rod 47. A striking plate 410 is fixedly connected to the top of the sliding plate 49. A spring 411 is provided between the V-shaped collecting groove 42 and the sliding plate 49.

[0027] The V-shaped collection groove 42 is in contact with the fixed platform 10 and the grinding disc 3. The V-shaped collection groove 42 is located on the displacement trajectory of the striking plate 410.

[0028] A protrusion is fixedly connected to the end of the rotating column 46 away from the rotating shaft 45, and a protrusion is fixedly connected to the top edge of the sliding plate 49. The circular surface of the protrusion of the sliding plate 49 is located on the movement trajectory of the circular surface of the protrusion of the rotating column 46.

[0029] According to the above structure, when the drive motor 44 is started, the rotation of the output shaft of the drive motor 44 drives the rotation of the rotating shaft 45, and the rotation of the rotating shaft 45 drives the rotation of the rotating column 46. When the protrusion of the rotating column 46 moves to the position of the protrusion of the sliding plate 49, the circular surface of the protrusion of the rotating column 46 pushes the circular surface of the protrusion of the sliding plate 49, causing the protrusion of the sliding plate 49 to move downward. The sliding plate 49 drives the striking plate 410 away from the V-shaped collection groove 42. When the circular surface of the protrusion of the rotating column 46 no longer pushes the protrusion of the sliding plate 49, the sliding plate 49 is reset under the elastic force of the corresponding spring 411. The sliding plate 49 drives the striking plate 410 to reset and move upward to strike the V-shaped collection groove 42, so that the debris naturally slides down the groove wall and is easily collected. Tapping the V-groove helps increase vibration within the groove, making it easier for slightly stuck or accumulated debris to fall off and enter the collection tank. This effectively breaks up debris buildup, ensuring that debris enters the collection tank quickly and thoroughly, preventing blockages and preventing debris from entering moving parts of the equipment, thus reducing equipment failure frequency and maintenance costs, extending equipment lifespan, ensuring a more precise and consistent grinding process, improving the appearance quality and processing accuracy of the final product, reducing downtime for cleaning, ensuring smooth production, improving overall production efficiency, reducing workshop pollution, and reducing the cost of regular cleaning and maintenance. It also avoids the difficulty and time cost of cleaning caused by long-term debris accumulation in equipment and workshops.

[0030] like Figures 1-5 As shown, a molding and grinding device for kettlebell production includes a dispersing device 5 on the output shaft of a drive motor 44. The dispersing device 5 includes a threaded rod 51, which is fixedly connected to the output shaft of the drive motor 44. A threaded sleeve 52 is threadedly connected to the outer wall of the threaded rod 51. A limit rod 53 is fixedly connected to the inner wall of a V-shaped collecting groove 42. A movable plate 54 is fixedly connected to the circumferential surface of the threaded sleeve 52. A V-shaped push plate 55 is fixedly connected to the bottom of the movable plate 54.

[0031] The lead screw sleeve 7 is in contact with the molding body 1, and the limit buckle 9 is in contact with the kettlebell 11.

[0032] The threaded sleeve 52 is in contact with the limiting rod 53, and the V-shaped push plate 55 is in contact with the V-shaped collecting groove 42.

[0033] According to the above structure, the drive motor 44 is started. The rotation of the output shaft of the drive motor 44 drives the rotation of the threaded rod 51. The rotation of the threaded rod 51 drives the movement of the threaded sleeve 52. The movement of the threaded sleeve 52 drives the movement of the moving plate 54. The movement of the moving plate 54 drives the movement of the V-shaped push plate 55. The movement of the V-shaped push plate 55 disperses the debris in the V-shaped collection trough 42, preventing debris accumulation, keeping the collection trough unobstructed, and ensuring that the working area is always kept clean and unobstructed. This improves the overall efficiency of the production line, keeps the working environment clean, reduces the risk of accidents, and makes the debris more evenly distributed, which is convenient for subsequent cleaning, sorting and recycling.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
