This invention relates to the field of hydraulic straightening machine technology, and discloses a slide rail type hydraulic straightening machine, including a machine base. The machine base contains a shaft clamping component for clamping a shaft to be processed, and a straightening component for straightening the shaft to be processed. The shaft clamping component consists of a rotating clamping assembly that clamps one end of the shaft to be processed. A hydraulic push rod extends and pushes a push head, which in turn moves the push rod. The movement of the push rod causes the rearmost arc-shaped seat to move, thereby causing the pressure head mounted on the arc-shaped seat to press against the deformed area of ​​the shaft to be processed. As the arc-shaped seat moves, it causes the outer and inner extension plates to move synchronously, thereby pulling the remaining five arc-shaped seats to move. This causes the remaining pressure heads to move together and press against the shaft to be processed, providing radial support and limiting for the shaft to be processed, preventing excessive pressure on the shaft.

This utility model discloses a discharge device for a double planetary mixer, comprising a main frame, a pressing mechanism mounted on the main frame, a storage cylinder, an exhaust structure, an inductive limit switch, and a limiting component. The pressing mechanism includes a pressing plate and a power unit, the power unit driving the pressing plate to move along the inner wall of the storage cylinder. The exhaust structure includes an exhaust pipe penetrating the pressing plate and an exhaust valve mounted on the pressing plate. The inductive limit switch is located at the lower end of the pressing plate and is used to sense the bottom of the storage cylinder and control the pressing mechanism to stop working. The limiting component is used to limit the position of the storage cylinder. This utility model achieves the effect of safely and efficiently discharging materials while avoiding over-compression.

The utility model discloses an edge banding machine for wooden furniture, which comprises an edge banding shell, and an edge banding mechanism is arranged in the edge banding shell. The edge sealing mechanism comprises two installation openings formed in the edge sealing shell, only two fixing plates are fixedly installed on the inner side walls of the two installation openings, a plurality of sliding rods are fixedly installed between the two fixing plates, and the multiple sliding rods are slidably connected with the same inverted-concave-shaped sliding block in a sleeved mode. Under the interaction of the edge sealing shell, the mounting opening, the fixing plate, the sliding rod, the inverted concave sliding block, the shaping edge sealing electric soldering iron block and the edge outlet mechanism, the sliding rod and the inverted concave sliding block in the edge sealing mechanism are matched with the spring, the position and pressure of the electric soldering iron block can be flexibly adjusted, the edge sealing device is suitable for edge sealing of furniture of different sizes, excessive pressure is avoided, the fixing plate is detachable, and the fixing plate is convenient to use. A guide shaft and a limiting ring groove in the edge outlet mechanism ensure that the edge sealing strip is stably conveyed, an anti-loosening barrel prevents the edge sealing strip from loosening, the edge sealing efficiency and quality are integrally improved, and operation is more convenient and faster.

The utility model relates to the technical field of gypsum board packing devices, and provides a gypsum board packing machine head which comprises a mounting plate, two rod seats fixedly arranged on the outer surface of the mounting plate, a second lead screw rotationally connected to the outer surface of one rod seat, and a limiting rod fixedly arranged on the outer surface of the other rod seat. The device is provided with a structure for adjusting the distance between the machine head and the film covering and packaging mechanism according to the size of the gypsum board, when facing the gypsum boards of different sizes, the adjustable structure can be flexibly adapted, and for the gypsum boards of small sizes, the adjustable structure can be flexibly adjusted. The distance between the machine head and the film covering and packaging mechanism is proper through adjustment, the film covering and packaging mechanism can be tightly attached to the gypsum board, slipping in the transportation and storage process is prevented, the product integrity is guaranteed, the distance is reasonably adjusted for the large-size gypsum board, excessive pressing of the machine head on the gypsum board is avoided, and the gypsum board is prevented from being damaged and cracked; it is ensured that the film covering and packaging mechanism normally plays a role, and packaging operation is smoothly completed.

This invention relates to the field of medical and nursing device technology, and discloses a hammock-type assisted turning bed and a turning method, including a bed frame body. The bed frame body includes multiple functional segments arranged sequentially along its length. Each functional segment is equipped with a bed surface driving mechanism and a support adjustment mechanism. The bed surface driving mechanism includes a roller winding device and a bed surface. Two roller winding devices are symmetrically arranged on both sides of the bed frame body of the functional segment. The two ends of the bed surface are wound around the rollers of the corresponding roller winding devices. The support adjustment mechanism is located below the bed surface and includes multiple electric cylinders arranged along the width direction of the bed frame body. The hammock-type assisted turning bed and turning method provided by this invention solve the problems of high risk of shear friction injury, high risk of pressure sores, poor comfort, and insufficient safety and adaptability in the practical application of existing technologies.
