This invention discloses a steam heating device for a corrugated board production line, belonging to the field of corrugated board production technology. The device includes a cardboard conveyor, a steam heating component, an anti-friction component, and a synchronous cleaning component. The steam heating component drives the heating chamber to rise, rotate, swing, and level to press the cardboard. The anti-friction component is driven to translate as the heating chamber swings downwards, synchronously driving the connected flexible metal hose to move vertically downwards, achieving dynamic height compensation of the pipeline and eliminating alternating bending stress at the hose root to prevent friction and leakage. The synchronous cleaning component translates with the anti-friction component, driving a cleaning scraper to slide along the bottom surface of the heating chamber to clean adhering scale, and utilizes a cam-assisted structure to perform height compensation during the swinging process, maintaining tight contact between the scraper and the surface. This invention achieves mechanical linkage between pipeline follow-up protection and automatic bottom surface cleaning, improving production efficiency and equipment stability.

The utility model discloses a beverage brewing device, comprising: a bracket assembly; a brewing cylinder disposed on the bracket assembly, the brewing cylinder defining a first axis, the brewing cylinder including a brewing cavity having a filling opening; a brewing head that moves relative to the brewing cylinder to selectively close the brewing cavity above the filling opening; a pushing piston engaged with the brewing cylinder, the brewing cylinder being capable of moving relative to the bracket assembly along the first axis; further comprising a dreg scraping mechanism, the dreg scraping mechanism including a first driving mechanism and a dreg scraping member, the first driving mechanism selectively driving the dreg scraping member to move relative to the brewing cylinder to scrape off powder dregs; the first driving mechanism is installed on the bracket assembly, the dreg scraping member is carried above the brewing cylinder, and during the movement of the brewing cylinder relative to the bracket assembly along the first axis, the dreg scraping member can establish or disconnect a transmission connection with the first driving mechanism. By controlling the connection / disconnection between the dreg scraping member and the first driving mechanism through the movement of the brewing cylinder, precise control of the dreg scraping action is achieved.

This invention provides an automatic slag removal mechanism for drying equipment, its installation method, and its application, belonging to the technical field of slag removal structures for drying equipment. The automatic slag removal mechanism includes a driven shaft seat, a driven roller, a slag removal pipe, a spiral shaft, and a transmission structure. Two driven shaft seats are provided and arranged opposite to each other. The driven roller is rotatably installed between the two driven shaft seats and is used for supporting and guiding the conveyor belt of the drying equipment during reversal. The slag removal pipe is fixed between the two driven shaft seats, parallel to the driven roller, and positioned on the side of the driven roller away from the conveyor belt. A notch is provided on the side of the slag removal pipe facing the driven roller. In the above solution, the automatic slag removal mechanism for drying equipment, its installation method, and its application realize the automatic scraping, collection, and conveying discharge of residue from the driven roller, without manual intervention or machine shutdown for slag removal, effectively improving slag removal efficiency, ensuring continuous operation of the equipment, and increasing production efficiency.

The application discloses a flexible pressure sensor sensitive layer preparation device, and belongs to the technical field of pressure sensor sensitive layer preparation, which comprises a mounting frame, traction rollers and a moving frame arranged on the mounting frame, and a second driving mechanism is arranged between the moving frame and the bottom plate of the mounting frame; a plate roller mounting plate is arranged on the moving frame, a third driving mechanism is arranged between the moving frame and the plate roller mounting plate, a plate roller is arranged on the plate roller mounting plate, and the plate roller is provided with a fourth driving mechanism at one end. The plate roller mounting plate and the moving frame are arranged below the traction rollers, so that the plate roller on the plate roller mounting plate can move along a first direction through the moving frame, the plate roller can move along a second direction through the plate roller mounting plate, and the moving frame can adjust the distance between the plate roller and the traction rollers, so as to adjust the pressure of the plate roller on the base material and realize the preparation of sensitive layers with different preparation requirements.
