The utility model discloses a film bubble shaping device convenient to cool, which relates to the technical field of film processing equipment and comprises a bearing table, three groups of concave frames are fixedly connected to the top end of the bearing table, a bearing roller is movably connected between the front end and the rear end in each concave frame, and a cooling component convenient for cooling film materials is arranged at the top end of each bearing frame. According to the film bubble shaping device convenient to cool, by arranging the backflow box, the water supply tank, the square flat pipe, the fan, the circulating pump, a water supply pipe, a controller, a bearing base, a cooling tunnel, a water inlet, a water outlet and a backflow pipe, when the film bubble shaping device convenient to cool is used, cold water in the water supply tank is pumped out through the circulating pump, water is pumped to the water inlet through the water supply pipe, and the cold water enters the cooling tunnel; and the fan continuously blows air to cool the square flat pipe, so that the temperature of the water flow is kept at a relatively low level, the function of accelerating cooling and shaping is realized, and the problem that the device does not have the function of accelerating cooling and shaping is solved.

The present application relates to a kind of pure mechanical friction brake and its working method, including input shaft disc, spacer, copper friction plate, steel friction plate, rear end plate, output shaft, spring, spring backing plate, bearing, pin, cam, lever, bearing.Compared with prior art, the pure mechanical friction brake of the present application is entirely composed of mechanical parts, the size of brake friction can be set by adjusting the friction plate and spring, the compression length of spring is adjusted by the extrusion of lever on cam, so as to adjust the extrusion force between friction plate, finally realize the conversion of brake and drive of cam, to realize the function of basic brake, at the same time, automatic parking can be realized when power failure occurs to deal with emergency.

The utility model relates to the technical field of valves, and discloses a pressing type petroleum mechanical valve which comprises a tubular valve shell, a sealing plug is inserted into the top end of the tubular valve shell, a threaded pipe is connected to the upper half portion of the tubular valve shell in a threaded mode, a sealing cover is arranged at the top end of the threaded pipe in a sleeved mode, and a valve rod assembly is arranged at the center of the sealing cover and the center of the sealing plug in a penetrating mode. An elastic assembly is arranged between the bottom end of the sealing cover and the outer wall of the threaded pipe, and the outer side of the elastic assembly is sleeved with a protection assembly. The rotary knob is screwed to drive the sealing cover to move up and down along the guide rod, so that the compressed length of the spring is adjusted, the extrusion force between the sealing circular truncated cone and the sealing ring is adjusted, and the purpose of conveniently adjusting the sealing pressure is achieved. The fixing ring is sealed through the sealing cover, the bottom end of the sleeve is sealed through the supporting ring, and therefore a sealing cavity is formed in the sleeve, and the spring is stored in the sealing cavity. And therefore, the purposes of coating the spring and preventing corrosion are achieved.
