The invention discloses a chain clip cooling device for a film producing machine. A group of 3 to 35 cooling nozzles facing a chain clip are respectively arranged on the outer side of a circulating operating guide rail of a chain of the chain clip and are connected with a cooling water pipe and / or a compressed air pipe. A gas pumping cover is arranged above each group of nozzles and the chain clip; the gas pumping cover is connected with an exhaust fan trough a gas discharge pipe for discharging vapor in time; last 1 to 10 nozzles of each group of nozzles are only connected with the compressed air pipe, air-cooled and further cooled; the water vapor flow of first 1 to 16 nozzles of each group of nozzles is constant; the compressed air pipe of middle 1 to 10 nozzles of each group of nozzles is provided with a solenoid valve which is connected to a water vapor integrated control center; the water vapor integrated control center is used for regulating the solenoid valve of the middle nozzles according to a signal of a temperature measuring probe at a clip entering position, so as to increase and decrease water smog quantity; an air-cooling cover behind the gas pumping cover is covered above the chain clip; and the air-cooling cover is connected with a blower through a blowing pipe to ensure that the chain clip is completely dried. In the device, the temperature of the chain clip is reduced to about 23 DEG C; the phenomenon of breaking a film due to higher temperature of the chain clip is completely avoided; and the quality and the yield of a stretching film are enhanced.

A compound manufacturing device and method for electric arc additive material and cryogenic rolling forming. The device includes a base and a workbench. The workbench is set on the base and can move horizontally on the base. module, temperature maintenance module and arc additive module, and a cryogenic treatment module is also arranged on the base. It also includes a compound manufacturing method of electric arc additive material and deep cold rolling forming. It also includes a compound manufacturing method of electric arc additive material and deep cold rolling forming. The invention combines arc material addition with cryogenic deformation. The cryogenic deformation utilizes the excellent plastic deformation ability of certain metal materials under cryogenic conditions and the fact that the cryogenic environment hinders dislocation movement and recrystallization behavior during the deformation process, thereby promoting the material Grain refinement improves material strength and toughness.

The invention relates to a throat drug application device, in particular to a handheld throat drug application device, and aims at providing the handheld throat drug application device which is capable of adjusting the drug spraying amount and the drug spraying angle and replacing a spray nozzle. According to the technical scheme, the handheld throat drug application device includes a mounting rack, an arc block, a swing bar, a hard water pipe, a spray nozzle, a first return spring, a cover plate, a convex block, a flexible pipe, a first one-way valve, a fixing plate, a water containing bag and the like; the mounting rack is placed at the top of a frame, the arc block is arranged at the middle of the top of the interior of the mounting rack, the swing bar is rotatably arranged at the frontside of the arc block, and the hard water pipe is connected to the left end of the swing bar and is located at the front side of the mounting rack. According to the handheld throat drug application device, by arranging the swing bar, the spray nozzle can swing up and down, and therefore people can spray drug to the throat in all directions; by arranging the convex block, the spray nozzle can be fixed and can be replaced, and bacterial infection is avoided; by arranging a plug, people can adjust the drug spraying amount of the spray nozzle.

The invention discloses a nozzle with pressure compensation function, a sprinkler irrigation belt and a processing method for the sprinkler irrigation belt. The nozzle includes an inner casing, an outer casing and an end cap, the inner casing is provided with a plurality of first water outlets on the circumferential wall, and the inner wall of the outer casing is provided with a plurality of water inlet blind holes matched with the first water outlets. There are also a plurality of first spray holes penetrating through the outer casing in the water inlet blind hole; the outer casing is sleeved on the outside of the inner casing and threaded to one end of the inner casing, and the water inlet blind hole and the corresponding first water outlet Arranged oppositely, an elastic sheath is provided between the inner sleeve and the outer sleeve, and the elastic sleeve is correspondingly sealed to the outer edge of the blind water inlet hole and the outer edge of the first water outlet.
