Description

Technical Field

[0001] The utility model belongs to the technical field of sheet processing equipment, and specifically relates to an intelligent special rotating roller table. Background Art

[0002] In a plywood production line, due to the heavy load borne by the plywood production line, it is very inconvenient to change the direction of the stack of boards. Currently, the traditional rotary gear method has a complex structure and requires a complex gear pair structure. For example, the universal corner device of the conveying table disclosed in Chinese Patent CN208828769U includes a corner tray, a rotating shaft, a rotating mechanism and a lifting mechanism; the rotating mechanism includes a motor, a first gear and a second gear; the motor is fixedly arranged below the conveying table; the first gear is fixedly sleeved on the rotating shaft of the speed reducer connected to the motor; the second gear is fixedly sleeved on the rotating shaft and meshes with the first gear; the top of the rotating shaft is detachably connected to the corner tray, and the bottom of the rotating shaft is connected to the lifting mechanism; a pressing plate is movably connected to the top of the conveying table; the pressing plate is adapted to the corner tray.

[0003] Another example is the sheet rotating table disclosed in Chinese Patent CN205675764U, where the rotating unit is a rotating oil cylinder with one end rotatably connected below the lifting inner sleeve mounting plate and the other end connected to the lower end of the rotating main shaft, and the rotating oil cylinder and the rotating main shaft form a rotating transmission connection.

[0004] The above-mentioned conveying tables all have the problem of complex structures. The rotating mechanism or the rotating unit needs to excavate a foundation pit below the production line for installation, which occupies a large area, has a high cost, is inconvenient for maintenance, and is dangerous to operate.

The slewing motor 206 drives the pinion gear 207 to mesh with the outer ring 303 of the slewing bearing. Since the outer ring 303 of the slewing bearing is stationary, the pinion gear 207 rotates along the outer ring 303 of the slewing bearing, thereby driving the slewing bracket 201 to rotate, realizing the rotation of the slewing device 2.

[0049] The working principle of this embodiment: The roller table assembly 1 can be lifted under the action of the lifting oil cylinder 203. At the initial elevation, the top surface of the roller unit 102 is lower than the top surface of the conveyor chain of the chain conveyor rack. The pallet is transferred into the roller unit 102 from the incoming plate direction by the transfer frame assembly 204 and stops above the roller unit 102. The roller unit 102 is lifted. At this time, the top surface of the roller unit 102 is higher than the top surface of the chain of the chain conveyor rack. After the rotation direction of the rotating unit is driven by the slewing motor 206 to drive the pinion gear 207, it is conveyed out by the roller unit 102.
