Description

Technical Field

[0001] The utility model relates to the technical field of dumbbell production, and more specifically, to a plastic spraying device for dumbbell production. Background Art

[0002] Dumbbells are a simple piece of equipment used to enhance muscle strength training. Their main material is cast iron, and some are covered with a layer of rubber. According to the material and craftsmanship, dumbbells can be divided into the following categories: plastic-dipped dumbbells, rubber-coated dumbbells, paint-coated dumbbells and wood-steel dumbbells. Long-term practice with dumbbells can modify muscle lines and increase muscle endurance. Regular exercises with heavy dumbbells can make muscles firm, strengthen muscle fibers and increase muscle strength.

[0003] After the dumbbells are produced, the dumbbell pieces need to be sprayed with plastic to extend the service life of the dumbbell pieces. At this time, a corresponding spraying device is needed. However, in the actual use of the existing spraying devices, the fastening mechanisms of the dumbbell pieces mostly adopt a fixed design, so that the spraying device can only spray plastic on a single side of the dumbbell piece. The operator needs to turn the dumbbell piece back and forth during the spraying process to ensure that the dumbbell piece is sprayed with plastic in all directions, which reduces the spraying efficiency of the dumbbell piece. Therefore, it is necessary to improve this. Utility Model Content

[0054] Then the operator starts the first motor 5, so that the rotating shaft 6 rotates with the second column 305, so that the top surface of the dumbbell piece is sprayed with plastic through the nozzle 17. When the spraying is completed, the operator starts the driving motor 401, so that the driving shaft 402 drives the active gear 403 to rotate, so that the driven gear 303 meshing with the active gear 403 rotates with the first column 304 and the second column 305 through the long rod 301.
