The ejection assembly includes two mounting slots, which are respectively located inside the two ends of the lower mold. A rectangular groove is formed on one side of each mounting slot. An electric push rod is fixedly connected to the inner wall of the rectangular groove. A bracket is fixedly connected to the inner wall of the mounting slot. An inclined block is slidably connected to the bottom wall of the bracket. A sliding rod is slidably connected to the top of the bracket. A disc is fixedly connected to the bottom end of the sliding rod. In this utility model, the automatic ejection of the roller core is achieved through the linkage of the electric push rod, the inclined block, the pulley, and the spring, solving the problem that improper force applied by operators during the removal process can easily damage and deform the surface of the rubber roller, affecting product quality.

This invention provides a disinfectant raw material filling and conveying device, relating to the field of disinfectant filling technology. The device includes a filling shell and further includes: a transport limiting mechanism located at the bottom of the inner side of the filling shell for transporting the bottles used for filling; and a filling storage chamber located at the top of the inner side of the filling shell. This disinfectant raw material filling and conveying device, by incorporating a following mechanism, uses a prism shaft to drive the traveling belt to operate in strict synchronization with the transport limiting mechanism. This ensures that the filling tube assembly moves dynamically with the bottle, maintaining alignment throughout the process. It completely eliminates the drawbacks of frequent start-stop operations in traditional linear filling and misalignment of the fixed head in rotary filling, achieving uninterrupted continuous filling operations, significantly improving production efficiency. Simultaneously, the absence of relative displacement throughout the process effectively avoids bottle shaking, tilting, and collisions, greatly reducing equipment failure rates and bottle wear, and significantly enhancing operational stability and reliability.

The application discloses an environment-friendly recycling treatment equipment for waste concrete, which comprises a vibrating feeder, a coarse crushing unit, a fine crushing unit, a vibrating screening machine and a plurality of belt lifting conveyors. The plurality of belt lifting conveyors are respectively arranged between the vibrating feeder and the coarse crushing unit, between the coarse crushing unit and the fine crushing unit, and between the fine crushing unit and the vibrating screening machine. The coarse crushing unit is a jaw crusher. The hydraulic floating gap adjusting structure can realize the elastic yielding structure with adjustable yielding force, controllable stroke, automatic reset and no influence on normal crushing granularity, can ensure that the hard objects can smoothly pass through, will not be stuck and broken, and is suitable for the treatment of waste concrete. In the modular movable tooth roller structure, the tooth plate can change the installation angle during installation. A single tooth plate can realize two-state installation. When only the installation angle of the tooth plate is changed without changing the tooth shape, other tooth plates do not need to be changed, and only the installation state needs to be changed.

The application discloses a T-shaped piston device with adjustable stages utilizing CO2 liquid-gas phase change energy, which comprises a T-shaped piston unit with adjustable stages, a power supply system and a valve controller; the power supply system and the valve controller are connected with the T-shaped piston unit with adjustable stages. The device provides fast, accurate and continuous pressure power for the piston stroke in the limited space of the cylindrical cylinder body, and can accurately show and reflect the relationship between the CO2 mass participating in the liquid-gas phase change and the specific stroke of the piston. The application further discloses a calculation method for converting phase change energy into the adjustable stroke of the T-shaped piston.

The utility model relates to a limit switch of an electric kickstand, and relates to the field of kickstand devices. The limit switch of the electric kickstand comprises a pin, a reed, a linkage shaft and a base, the pin is fixed on the base, the base is fixed in the electric kickstand, the reed is movably connected to the base, the linkage shaft is connected to the base in a sliding mode, the linkage shaft drives the reed to slide when being stressed, the limit switch further comprises a sliding seat connected to the base in a sliding mode, and the reed is fixed on the side, facing the linkage shaft, of the sliding seat. A sleeve is fixed to the other side of the sliding base and sleeved with a reset spring, one end of the reset spring abuts against the sliding base, the other end of the reset spring abuts against the base, a receding groove for providing a sliding space for the sleeve is formed in the base, and when the linkage shaft drives the sliding base to slide, the end of the sleeve slides into the receding groove. The length of the receding groove is larger than the sliding stroke length of the sleeve when the motor of the electric kickstand is closed. The kickstand has the effect that the limiting switch is not prone to being damaged when the kickstand continues to be pulled in the motor shutdown state.

This application relates to an instrument transformer coil assembly device, belonging to the technical field of instrument transformer coil assembly, which includes a base plate, an iron core, and a frame. The main frame and positioning reference of the device can be formed by the flange sheet metal, guide seat, and limiting plate on the base plate. The placement groove on the side of the guide seat can accurately accommodate the iron core, ensuring its fixed position during assembly. The pushing hole of the limiting plate can provide precise guidance for subsequent pressing actions. A cylinder is used as a power source, and its push rod, through the limiting block, ensures controllable stroke. The end fixing block, fixing plate, and roller can form a pressing head. The roller can contact and push the insertion rod. The iron core is pre-placed in the placement groove, and the central insertion rod acts as a guide shaft. When the cylinder drives the push rod forward, the roller pushes the insertion rod to deflect. After the deflection is complete, the frame can be fitted onto the surface of the insertion rod, thus completing the core mechanical assembly action.

This utility model discloses a side-cutting mold for laptop casing, used for side-cutting the sidewall of C-part casing. The side-cutting mold includes an upper mold and a lower mold that cooperates with the upper mold. The upper mold includes an upper mold assembly, several elastic mechanisms disposed within the upper mold assembly, an inner ejector plate connected to the upper mold assembly, and an upper mold cutting edge disposed on one side of the inner ejector plate. The lower mold includes a lower mold assembly, a contour plate disposed on the upper end of the lower mold assembly for supporting the casing, several positioning components disposed on the contour plate, a driving assembly disposed on the lower end of the contour plate, a side-cutting assembly distributed on one side of the driving assembly, and two spaced lower mold cutting edges. The side-cutting assembly includes a lower mold punch adapted to the shape of the area to be cut. In the mold-closed state, the inner ejector plate presses against the upper end of the casing, the upper mold cutting edge can abut against the outside of the upper part of the area to be cut on the casing, and the lower mold punch is located inside the area to be cut on the casing. The cutting edge is divided into an upper mold cutting edge and a lower mold cutting edge according to the area to be cut, which improves the structural strength and prevents material jamming.
