The utility model relates to the field of automatic unpacking equipment, in particular to anti-scattering automatic unpacking equipment for short fibers. Comprising a conveying belt, an unpacking device is installed on one side of the conveying belt, a collecting box is installed on one side of the unpacking device, an adjusting structure is arranged on the upper surface of the conveying belt and comprises a protection plate, the protection plate abuts against the conveying belt, and two fixing grooves are formed in the two sides of the protection plate; two connecting frames are fixedly connected to the two sides of the conveying belt, and auxiliary rods are rotationally connected to the inner walls of the connecting frames. The short fiber anti-scattering automatic unpacking equipment has the advantages that short fibers can be prevented from being driven by air to scatter in the unpacking process, certain loss caused by the scattered short fibers is prevented, meanwhile, the concentration of the fibers in the air is effectively reduced, harm to health of workers is reduced, and the unpacking efficiency is improved. And the safety of the working environment is protected.

This utility model relates to the technical field of grinding devices, specifically disclosing a grinding device for sheet metal processing. It includes a wide-surface grinding mechanism for the sheet metal, a long-side grinding mechanism for the sheet metal on one side of the wide-surface grinding mechanism, and a sheet metal conveying mechanism at the end of the wide-surface grinding mechanism away from the long-side grinding mechanism. The wide-surface grinding mechanism of this design uses adjustable grinding rollers arranged symmetrically. The height of the lifting frame is precisely controlled by a cylinder, ensuring close contact between the grinding rollers and sheets of different thicknesses, guaranteeing uniform grinding pressure distribution. Simultaneously, the high-speed rotation of the grinding rollers driven by dual motors, combined with the continuous feeding of the conveyor belt, allows for fine grinding of the entire wide-surface area in one pass, avoiding the surface unevenness caused by uneven force in traditional manual grinding. For the long-side, a linkage structure between a threaded sleeve and a limiting rod allows the two grinding discs to adaptively adjust their spacing, precisely clamping the edge of the sheet metal and grinding it synchronously.

The utility model discloses a kind of cable hoisting devices, it is related to the installation technical field of cable or wire.A kind of cable hoisting device, including support frame, lifting frame and fixed base, support frame and lifting frame are fixedly connected on the top of fixed base by bolt, lifting structure, lifting structure is located on lifting frame, lifting structure includes two fixed plates, rotating shaft, two threaded rods, drive motor, two bevel gear rings and two bevel gears, two lifting grooves are set up in the side of lifting frame away from support frame, transmission groove is set up in the both sides of lifting frame, cable placing frame is rotated around support plate by electric telescopic link, realize the automatic conversion of cable from horizontal lifting state to inclined placement state, without manually pushing and pulling cable, avoid the physical exertion problem of manpower pushing cable onto rack, simultaneously, also avoid the cable sliding risk caused by artificial operation out of step, further improve the practicality of cable lifting.

This invention discloses an intelligent production line for prefabricated steel structure wall panel frames, divided into a material processing area, a logical sorting area, and an assembly and forming area according to the process flow. The material processing area includes a movable and changeable uncoiling and feeding mechanism and a keel machine. The logical sorting area is equipped with a sorting mechanism and a sorting controller, including a pushing unit and a flipping unit. The assembly and forming area includes an assembly and dragging mechanism, a conveyor line, and a nailing machine. The core of the invention lies in the sorting controller's logical comparison of the preset installation position parameters of the keel truss to be processed in the wall drawings—including the lowest point height value β and the length value λ—with the wall height boundary line h and the length threshold α. This comparison then controls the sorting execution module to adaptively sort the keel truss to the upward flipping area, the downward flipping area, or the short material area. This invention achieves adaptive intelligent sorting and attitude pre-adjustment of the keel truss based on spatial position parameters, significantly improving the flexibility, assembly efficiency, and quality stability of prefabricated steel structure frame production.

The invention belongs to the field of bridge expansion joints, and provides a bridge expansion joint construction device which comprises a comb-shaped plate and a supporting frame, a magnetic attraction assembly is installed in the middle of the supporting frame, a lifting rope assembly used in cooperation with the magnetic attraction assembly is installed on one side of the top of the supporting frame, and two traveling assemblies are symmetrically installed at the bottom of the supporting frame. The supporting frame is provided with a power mechanism for driving the two sets of driving assemblies to operate synchronously, and the middle of the supporting frame is further provided with a direction adjusting and controlling assembly used for adjusting and controlling the overall direction of the device.
