The utility model discloses a detector for sampling inspection of the thickness of a non-setting adhesive, and relates to the technical field of non-setting adhesive detection. The device comprises a bottom plate, an electric lifting rod is fixed to the right portion of the upper end face of the bottom plate, a U-shaped strip is fixed to the lifting end of the electric lifting rod, a laser transmitter is arranged on the upper end face of the U-shaped strip, a laser receiver is arranged on the lower end face of the U-shaped strip, sliding openings are formed in the two end faces of the U-shaped strip, and two sets of air cylinders with piston ends located in the sliding openings are fixed to the side wall of the U-shaped strip. A synchronous strip is arranged on the inner side of the U-shaped strip, sliding plates in bolted connection with the piston ends of the air cylinders are fixed to the upper end and the lower end of the synchronous strip, and a controller is fixed to the upper end face of the bottom plate. According to the utility model, the air cylinder and the electric lifting rod are matched for use, so that the non-setting adhesive strips with different widths and different heights can be subjected to spot check, and meanwhile, the synchronous strip, the laser transmitter and the laser receiver are matched for use.

This utility model discloses a reverse evaporation device, relating to the field of evaporation equipment technology. It includes a fixed frame, with a condenser threaded tube fixedly embedded on one side of the inner wall of the fixed frame; a control structure located within the fixed frame; and the control structure comprising a threaded rod, an external toothed rotating ring, a fixed rotating ring, two fixed rods, a movable component, and two sets of cleaning brushes. The outer wall of the threaded rod is rotatably embedded within the fixed frame, and the inner walls of both the external toothed rotating ring and the fixed rotating ring are rotatably fitted onto the fixed frame. One end of each of the two fixed rods is fixed to the external toothed rotating ring. Through the threaded rod, external toothed rotating ring, fixed rotating ring, fixed rods, and movable component, the up-and-down movement of the movable component can be controlled, as can its rotation. This allows the movable component to rotate and move up and down around a central point on the condenser threaded tube, enabling the cleaning brushes to scrape away condensate from the surface of the condenser threaded tube, allowing the condenser threaded tube to directly contact the air, thereby increasing the condensation effect.
