The present application relates to the technical field of cable processing, and discloses a cable coating device and a coating method. The device is used for coating the ground wire on the cable to be processed, and comprises a coating furnace, a cable carrier and a coating module. The coating furnace contains coating. The cable to be processed is detachably installed on the cable carrier. The coating module comprises at least one coating spoon provided with a containing groove for containing the coating. The coating spoon can move between a coating position and a replenishment position. When the coating spoon is at the replenishment position, it extends into the coating furnace. When the coating spoon is at the coating position, the top of the containing groove is located in a working plane parallel to the horizontal plane, and the ground wire on the cable to be processed located in the working plane is immersed in the coating contained in the containing groove. The design that the top of the containing groove is flush with the ground wire enables the ground wire to contact the coating higher than the top of the containing groove, so as to realize the coating operation of the ground wire in the horizontal plane and improve the coating efficiency.

This utility model discloses a sperm cryopreservation tube for sealing, relating to the field of cryopreservation technology. The technical solution includes a tube body with symmetrically fixed blocks on its inner side. A cap is movably connected inside the tube body, and an inner sleeve is fixedly connected inside the cap. A pressing assembly is provided inside the inner sleeve, including a pressing pestle and a button. A sealing sheet is movably connected inside the cap, and a movable plate is fixedly connected to the outside of the sealing sheet. A second spring is fixedly connected to the outside of the movable plate, with one end of the second spring away from the movable plate fixedly connected to the inner wall of the cap. A groove is provided on the inner wall of the tube. By using the pressing assembly, the sealing sheet is pressed, causing it to slide on the inner sleeve and engage in the groove to seal the injection port of the tube body, preventing the cap from falling off and causing liquid nitrogen contamination. This simplifies the process of hand-held rotation when sealing the cap and tube body, quickly sealing the injection port of the tube body, preventing excessive air from entering the tube, and ensuring the sperm preservation effect.

The invention belongs to the technical field of liquefied petroleum gas treatment, and particularly discloses a liquefied petroleum gas dehydrator which comprises a treatment tank, a supporting seat is fixedly connected to the bottom of the treatment tank, an inlet hopper is fixedly connected to the top of the treatment tank, and a connecting pipe is inserted into and fixedly communicated with the bottom of the treatment tank. Control valves are arranged on the connecting pipe and the inlet hopper, the bottom of the connecting pipe fixedly communicates with a collecting tank, and a second collecting assembly and a first collecting assembly which are used for preventing gas from entering are sequentially arranged in the treatment tank from top to bottom; one side of the outer wall of the treatment tank is provided with a driving assembly used for being matched with the second collecting assembly and the first collecting assembly in a switching mode, gas and liquid can be separated, then gas dissipation is greatly reduced, meanwhile, a first extrusion plate can extrude a water absorption part, then water contained in the water absorption part is thoroughly extruded out, and the water absorption part is prevented from being damaged. And the drainage efficiency is improved.

The invention belongs to the technical field of pregnant woman and baby boards, and discloses a formaldehyde-free pregnant woman and baby board and a production method thereof.The formaldehyde-free pregnant woman and baby board comprises a wood board layer, a glue layer, distance shrinkage lines and an activated carbon layer, the glue layer is arranged at the top end of the wood board layer, and the activated carbon layer is fixed to the top end of the wood board layer; a plurality of sets of distance shrinkage lines are formed in the wood board layer and are arranged at equal intervals relative to the central axis of the wood board layer, and an antibacterial film is arranged on the surface of the wood board layer. The surfaces of a third servo motor, a limiting frame and a second screw rod can be embossed when the device is used for producing the pregnant and baby board, so that distance shrinkage grains are formed on the surface of the pregnant and baby board, the contact distance between air and an activated carbon layer is shortened, and the contact space between the activated carbon layer and the air is expanded; the harmful substance absorption efficiency of the pregnant and baby board is improved by enlarging the contact area of the activated carbon layer and air, and then the safety of a user using the pregnant and baby board is protected.

The present invention relates to a cleaning robot. The cleaning vehicle body shell structure of the cleaning robot comprises a first hinge assembly, a vehicle frame and a vehicle shell covered on the outside of the vehicle frame; a water tank is arranged in the vehicle shell, a water tank cover is connected to the top of the water tank, and one end of the water tank cover is hinged to the vehicle frame through a first hinge assembly; the first hinge assembly comprises a hinge, an articulated arm and an articulated seat, one end of the hinge is connected to the articulated arm, the other end of the hinge is connected to the articulated seat, the articulated arm is used to connect to the water tank cover, the articulated seat is used to connect to the vehicle frame, and the articulated seat has an escape space; when the water tank cover is closed relative to the water tank, part of the articulated arm can be accommodated in the escape space; when the water tank cover is opened relative to the water tank, part of the articulated arm can be moved out of the escape space, thereby reducing the wear of the water tank cover during the opening and closing process relative to the water tank, and ensuring that the water tank cover has sufficient tightness relative to the water tank.
