Description

Technical Field

[0001] This utility model relates to the field of automatic oil spraying technology, and in particular to an automatic oil spraying device for the surface of a hanging silicone watch strap. Background Technology

[0002] Silicone watch straps are made from 100% pure natural solid silicone rubber using a hydraulic press. The straps themselves possess a certain degree of tension and flexibility, making them easily deformable and instantly recovering their shape. Silicone watch straps are characterized by wear resistance, high temperature resistance, non-deformation, non-toxicity, odorlessness, and no side effects on the human body. They are also soft, crack-resistant, have a long service life, and do not irritate the skin. Silicone watch straps are truly green and environmentally friendly accessories. The main purpose of spraying oil onto the surface of silicone watch straps is to enhance the product's feel and aesthetics, while also improving wear resistance and dust resistance. Spraying oil makes the surface of the silicone watch strap smoother and flatter, less prone to dust accumulation, and provides good wear resistance and adhesion. Furthermore, spraying oil also prevents the silicone watch strap from absorbing dust, keeping the surface clean and smooth.

[0003] The utility model disclosed in CN218167471U relates to an automatic oil spraying device for hanging silicone watch straps, comprising an oil receiving tank and a connecting frame. The connecting frame has sliding grooves on both sides, with a support slidably connected to each groove. A suspension block is disposed between two supports, and the suspension block has multiple slots. Each slot on the suspension block has a leakage groove and a clearance groove. A rack is disposed on one side of the connecting frame, and gears and a motor are disposed on the supports. A linear module is disposed on the connecting frame, and a three-sided oil spraying assembly is disposed on the linear module. The three-sided oil spraying assembly includes a side plate, an upper nozzle, a front nozzle, a back nozzle, a connecting arm, a rotary cylinder, and a flipping plate. The beneficial effects of this utility model are: it can simultaneously spray multiple sides of the silicone watch strap, resulting in high efficiency; the oil spraying process eliminates the need for manual flipping, thus improving product quality.

[0004] The existing technology requires the silicone watch strap to be placed in a slot for oil spraying. Because the bottom of the watch strap is blocked, the watch strap needs to be flipped over for a second oil spraying operation, which reduces the oil spraying efficiency. Therefore, a hanging automatic oil spraying device for silicone watch straps is needed to meet people's needs. Utility Model Content
