The application relates to the technical field of hub polishing, and particularly discloses a hub production polishing device, which comprises a base and further comprises: a polishing cylinder arranged on the base and internally provided with abrasive; a lifting table arranged on one side of the base and capable of performing lifting movement; a positioning disc located above the polishing cylinder and connected with the lifting table and capable of lifting and rotating under the drive of the lifting table; and a positioning assembly arranged on the positioning disc and comprising a plurality of clamping blocks capable of moving close to or away from each other and used for clamping and positioning the hub; the hub production polishing device realizes a 'rotation and automatic reciprocating lifting' compound motion mode of the hub through a lifting mechanism, the contact between the hub and the abrasive is more sufficient and intense, the polishing process is accelerated, and under the cooperation of the limiting assembly and the rolling shaft structure capable of rolling in the clamping block, the hub can automatically and smoothly change the clamping position in the polishing process, and the polishing dead angle problem caused by the shielding of the traditional clamp is solved.

The application discloses a plastic tray conveying device and relates to the field of logistics component transportation, which comprises a machine box, a fixed mold, a movable mold, a conveying assembly comprising a hydraulic moving assembly, the hydraulic moving assembly comprising a hydraulic cylinder and a multidirectional moving component connected to the fixed end of the hydraulic cylinder, the movable end of the hydraulic cylinder being fixedly connected with a connecting table, the connecting table being rotatably connected with a rotating shaft, one end of the rotating shaft being connected with a driving motor, the other end of the rotating shaft being connected with a transmission shaft, the other end of the transmission shaft being connected with a grabbing component, the plastic tray being conveyed to the outside of the machine box for stacking after being grabbed and demolded, and the conveying assembly being further connected with a surface grinding assembly for trimming excess material during the conveying of the plastic tray. The device has the advantages that the waste material generated by pouring on the surface of the plastic tray can be removed during the grabbing and conveying of the plastic tray, the end surface of the plastic tray can be ground, the product conveying efficiency is improved, and the waste of manual resources is reduced.
