This invention discloses a protective mechanism for a fully automatic resistance welding can body welding machine, belonging to the field of metal packaging container manufacturing equipment, including a base. By setting up a braking mechanism, when the resistance welding can body welding machine is working, a hydraulic rod drives the protective cover downwards to cover the welding area. The downward movement of the hydraulic rod also drives the connecting frame downwards, thereby drawing hydraulic oil from the cylinder into the piston cylinder. This causes the two calipers inside the brake disc to move inwards along with the blocking block, releasing the abutment limit on the brake disc. Once the protective cover is in place, the welding mechanism can operate normally. After welding is completed, the hydraulic rod drives the protective cover upwards to reset, the calipers reset and clamp the brake disc, achieving mechanical locking. This completely avoids the safety risk of the resistance welding head starting prematurely due to electrical faults or sensor failures causing the protective cover to not be in place. No additional electrical control or sensors are required, reducing equipment cost and complexity, and significantly improving operational safety.

The invention relates to the technical field of inorganic composite materials, in particular to a plant fiber composite reinforced light anti-scratching gypsum board. Plant short fibers adopted by the gypsum board are subjected to calcium hydroxide solution dipping and sulfur dioxide gas fumigation treatment, a calcium sulfite / calcium sulfate microcrystalline coating layer is generated on the surfaces of the plant short fibers in situ, the interface bonding force of the fibers and a gypsum matrix is enhanced, and during preparation, the process of dry mixing and wet mixing is adopted to ensure that components are uniform; and rapid dehydration and high-pressure compaction of the slurry are realized through a process of combining vacuum filtration and hot press molding. The gypsum board prepared by the invention has excellent flexing resistance and impact strength while keeping light weight, and solves the problem of insufficient mechanical properties of the traditional light gypsum board.

This invention relates to the technical field of functional textile materials and electromagnetic shielding materials, specifically to a method for preparing a flexible meltblown fabric microwave absorbing material, overcoming the shortcomings of traditional microwave absorbing materials such as rigidity, heaviness, and poor flexibility. Using polypropylene meltblown fabric as a flexible matrix, surface adhesion is improved through dual pretreatment of ultrasonic cleaning and plasma modification. Ni-Zn ferrite is used as a single absorbing agent, and a uniform and stable absorbing slurry is prepared through coupling modification, ball milling, high-speed stirring, ultrasonic dispersion, and secondary high-speed stirring dispersion processes. This slurry is then subjected to ultrasonic-assisted impregnation and curing. The microwave absorbing material prepared by this invention exhibits excellent absorption performance in the Ka band (26.5~40GHz), with a minimum reflection loss of -18dB and an effective bandwidth of 6.5GHz, while maintaining the lightweight and flexible characteristics of meltblown fabric. The process is simple, controllable, and scalable, and can be widely applied in wearable electronics, electromagnetic shielding, and other fields.
