The utility model discloses a book cover binding device for printing, which comprises a binding table and book covers stacked on the binding table, positioning plates are arranged around the book covers, a suction mechanism is arranged right above the book covers, and a lifting cylinder for driving the suction mechanism to lift is connected to the binding table in a swinging manner. The suction mechanism comprises a flexible suction cup for creating sealing conditions, a round pipe for limiting airflow, a sealing rubber block for controlling the airflow, a drawing and inserting rod for pulling the sealing rubber block and a motor for controlling the drawing and inserting rod to move. By arranging a mounting block and a connecting rod, lifting of a suction mechanism is conveniently controlled, book covers are conveniently sucked, by arranging a driving screw rod, a limiting rod and a drawing and inserting rod, air pressure in a round pipe is conveniently controlled, a flexible suction cup has the suction effect, and therefore the binding device for printing has the effect of stably transferring the book covers; and the purpose of improving the binding efficiency is further achieved.

The utility model relates to the technical field of textile machinery, and discloses an air duct cloth cooling device which comprises a rack, two supporting plates are fixedly arranged at the top end of the rack, a plurality of first water-cooling rollers are rotatably arranged at the tops of the supporting plates, the rack is slidably connected with a lifting plate, a plurality of second water-cooling rollers are rotatably arranged at the bottom end of the lifting plate, and the water-cooling rollers are rotatably arranged at the bottom end of the lifting plate. A reinforcing assembly for reinforcing the lifting plate is arranged at the top end of the lifting plate, a winch is fixedly installed at the top end of the rack, and a steel wire rope is installed on a winding drum of the winch. By sliding and lifting the lifting plate, the second water-cooling roller can be heightened, the air duct cloth can be conveniently laid on the first water-cooling roller, by controlling the lifting plate to descend, the second water-cooling roller and the first water-cooling roller are staggered, the second water-cooling roller and the first water-cooling roller can guide the air duct cloth, the contact area between the air duct cloth and the first water-cooling roller and the contact area between the air duct cloth and the second water-cooling roller are increased, and the air duct cloth can be conveniently laid on the second water-cooling roller. And double-sided cooling can be carried out on the air duct cloth.

The utility model discloses bottle valve airtightness testing machine belongs to gas cylinder bottle valve airtightness test technical field, including box and water tank assembly, water tank assembly is located the inside of box, the right side of box top is provided with right side cover door, both sides of right side cover door rear side all are provided with hinge, both sides of right side cover door rear side all are through the hinge with the movable joint of box, the bottom of right side cover door is provided with auxiliary support structure, the inside of box is provided with the pressurizing mechanism for water tank assembly pressurization, through setting up box, water tank assembly, right side cover door, hinge, auxiliary support structure and pressurizing mechanism, have solved the existing gas cylinder bottle valve testing machine only to valve carries out 1.2 nominal pressure under the external airtightness test, does not carry out 0.05MPa's low pressure external airtightness test, gas cylinder bottle valve testing machine does not carry out internal airtightness test to valve and the problem that gas cylinder bottle valve testing machine does not have gas source pressurizing device and leads to external gas source test pressure deficiency.

This disclosure relates to the technical field of tooling for disassembling and assembling quenching heads for rolling mills. One embodiment of this disclosure provides a tooling for facilitating the disassembly and assembly of quenching heads, comprising: a support base, a front groove, and a rear groove. Both the front and rear grooves are formed on the surface of the support base. A mounting seat is disposed outside the support base. A docking assembly is disposed between the support base and the mounting seat. An outer frame is fixed to the side surface of the mounting seat. A lifting assembly is disposed on the outer frame, including a lifting frame. The lifting frame is disposed on the outer frame and has a lifting seat. A vertical screw is rotatably connected inside the outer frame, and the lifting frame and the vertical screw are connected by a threaded connection. This technical solution solves the technical problem in the prior art where the disassembly and assembly of a single quenching head requires multiple operation steps, and the disassembly of the outer and inner layers requires the use of different tools alternately. Frequent tool switching and component handling can easily lead to operational errors and even damage to the surface of the rolling mill.
