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.
