This utility model relates to the field of food processing equipment and discloses an automatic pressure relief device for an empty cake baking box. It includes: a baking box body, with an inner baking liner inside; a door rotatably connected to one side of the outer wall of the baking box near the inner baking liner; and heating elements and baking racks installed inside the inner baking liner. It also includes a pressure relief mechanism, comprising an exhaust pipe connected to the internal space of the inner baking liner and an intake pipe connected to the outside air, each equipped with a first / second solenoid valve and an exhaust fan at the outlet. The control system uses a timing unit and a temperature sensor for coordinated control. This utility model achieves precise, unmanned pressure relief operation, replacing the traditional manual door opening method. It can automatically exhaust and cool according to a preset program, solving the problem of cakes bursting due to inaccurate manual operation, thus ensuring baking quality and significantly improving product yield and stability.

The present application relates to the technical field of laser welding, and particularly relates to a collinear laser welding workstation based on modularization and a control method thereof, which comprises a base, a position moving unit used for carrying and moving aluminum plate to be welded, a laser welding unit used for emitting laser to a welding interface of the aluminum plate to form a molten pool, a monitoring unit used for monitoring the area of the welding interface, the burr quantity of the molten pool and the vibration intensity of the aluminum plate, and a control unit used for controlling the position moving unit and the laser welding unit to perform a welding test, and adjusting the laser welding temperature of the laser welding unit according to the area variation of the welding interface in the welding test, or correcting the target area of the welding interface according to the burr quantity of the molten pool, and adjusting the laser emission power according to the vibration intensity of the aluminum plate. The present application realizes the improvement of welding stability.
