This utility model discloses a leak-proof device for the feed inlet of a shot blasting machine, comprising: a hook-type shot blasting machine, wherein a traveling hook is movably mounted on the hook-type shot blasting machine; a clearance groove, formed in the top of the hook-type shot blasting machine, wherein a guide groove plate is fixedly connected to the top of the clearance groove, and the inner side of the guide groove plate is hollow; a servo motor, installed on the top of the hook-type shot blasting machine, wherein a baffle turntable is fixedly connected to the motor shaft of the servo motor, and a mating groove is formed through the baffle turntable. This application, by setting the baffle turntable to cooperate with the guide groove plate, allows the baffle turntable to shield the top of the guide groove plate when the traveling hook passes through the mating groove, using the turntable's own structure to prevent steel shot from splashing from the clearance groove. The sealing structure of the baffle turntable is more compact, making it difficult for steel shot to penetrate, significantly improving the leak-proof effect and reducing steel shot waste; the mating groove always corresponds to the position of the hook, avoiding sealing gaps caused by hook movement, achieving dynamic sealing, and further preventing steel shot splashing.

This utility model discloses a composite multifunctional sealing gasket, including an outer gasket body and an inner gasket body disposed on the lower outer side of the outer gasket body. Both the outer and inner gasket bodies comprise an aluminum foil layer, a cardboard layer, and an adhesive layer, respectively. The circumference of the inner gasket body is smaller than that of the outer gasket body. A silicone air bladder is disposed on the lower outer side of the outer gasket body, and an inner cavity is disposed on the inner side of the silicone air bladder. In this invention, after opening the bottle, the user can invert the gasket and replace it on the bottle opening. When the silicone air bladder contacts the inner wall of the bottle opening, it will deform under pressure, fully conforming to the shape of the inner wall of the bottle opening to form a tight seal. This sealing method effectively fills any tiny gaps that may exist at the bottle opening, greatly reducing the risk of food or medicine leakage and the entry of impurities such as air and moisture, providing reliable secondary protection for the opened product.

According to the scheme, the sealed heat dissipation type control mainboard comprises a sealed shell formed by a metal top cover and a metal bottom cover, a first equal-height column and a second equal-height column are arranged in the sealed shell and used for fixing and lifting the control mainboard, and a heat dissipation gap is reserved between the mainboard and the bottom cover. Second equal-height columns are installed around the control mainboard chip and make close contact with the control mainboard chip through a heat dissipation base, the top of the heat dissipation base is flush with the top cover, and the sealing performance is guaranteed through a sealing convex ring and a groove. The heat dissipation base is made of pure copper and is subjected to electroplating treatment, the heat dissipation tooth blocks are made of graphene reinforced composite aluminum-based materials, the top cover and the bottom cover are made of aluminum alloy and magnesium alloy, and honeycomb-shaped grooves are formed in the surface of the top cover to enhance the heat dissipation effect. In addition, a temperature sensor is arranged in the heat dissipation base, a fan installation position is reserved, and efficient and intelligent heat dissipation is achieved.
