The invention discloses auxiliary film covering equipment for display screen production and processing, and relates to the technical field of display screen production and processing, the auxiliary film covering equipment comprises a processing platform, a conveyor belt is arranged at the upper end of the processing platform, a rack is fixedly erected at the upper end of the processing platform, and a film covering limiting conveying mechanism is arranged on the inner side of the rack. According to the film laminating device disclosed by the invention, a movable block moves to drive the angle of an auxiliary abutting rod to change through stretching and retracting of a hydraulic telescopic cylinder rod and the deformation effect of an elastic tension elastic wire, so that the auxiliary abutting rod jacks up an abutting rod I, and a film touch pressing roller performs tight fitting rolling in the direction of a film to assist in film laminating work; and in cooperation with the additional arrangement of the arc-shaped supporting and pressing plate, a reverse pushing force can be applied to the first abutting rod, it is guaranteed that the film touch pressing roller is attached to the surfaces of the film and the display screen all the time, the effectiveness of film covering is enhanced, automatic film covering is achieved, and meanwhile bubbles generated during film covering can be removed and discharged slowly.

The utility model discloses a piano cover closing buffer structure which comprises a piano main body, a piano cover is rotatably connected to the piano main body, sliding cylinders are connected to the two sides of the piano main body respectively, sliding rods are slidably connected in the sliding cylinders in a sleeved mode, air channels are formed in the bottom ends of the sliding cylinders, studs are connected to the sliding cylinders in a threaded mode, and the studs are connected to the piano main body in a sleeved mode. According to the piano cover closing buffer structure, when the piano cover is pushed to be closed, the swing rod pushes the sliding rod to slide towards the interior of the sliding cylinder, air in the sliding cylinder is slowly exhausted from the air channel, and therefore the piano cover is slowly rotated to be closed under the gravity, and the piano cover is not prone to falling off. And when the closing speed of the piano cover is still too high, the stud is rotated by a screwdriver, so that the smaller air hole is communicated with the air passage, the air flow is reduced, and the purpose of controlling the closing speed is achieved.

This utility model discloses a soy sauce bottle cap. The lower cap is mounted on the soy sauce bottle, and its lower and upper sidewalls are respectively provided with a first outer edge and a second outer edge. The upper cap includes a bottom ring and a flip-top hinged to the bottom ring. A step is provided on the inner wall of the bottom ring. The upper end of the flip-top has a through hole penetrating its body, and an annular groove is provided inside the flip-top next to the through hole. The bottom ring is fitted onto the lower part of the lower cap, and the step abuts against the lower end of the first outer edge. The flip-top is fitted onto the upper part of the lower cap, and the second outer edge is interference-fitted into the annular groove. A filter layer is disposed inside the flip-top and covers the through hole. This utility model allows fermentation gases generated during soy sauce storage to be discharged through the through hole on the flip-top. The filter layer provides a barrier effect, enabling slow discharge, filtration, and adsorption, preventing the accumulation of fermentation gases in the soy sauce bottle due to prolonged periods without opening the cap, and preventing gas from rushing out when the flip-top is opened.
