Unwinding and winding device and use method thereof

Abstract

The invention discloses an unwinding and winding device and a use method thereof. The unwinding and winding device comprises a winding platform mounted on a support. A gas-expansion shaft is rotationally mounted on the winding platform. The lower end of the gas-expansion shaft is connected with a driving shaft of a driving motor through a transmission device. In a deflated state, the diameter of the gas-expansion shaft is smaller than the diameter of a reel which is used for winding veneers, and after being inflated, the gas-expansion shaft can clamp the reel from the inner side and drive thereel and a winding shaft to rotate synchronously. The winding platform is provided with at least two ejecting blocks symmetrically arranged along the gas-expansion shaft, the ejecting blocks are arranged on the winding platform in a lifting mode, and the lower ends of the ejecting blocks are connected with telescopic rods of driving cylinders. The winding process in the last production stage of veneers is achieved through cooperation of a pressing plate and the gas-expansion shaft, so that obtained veneer rolls are orderly in end face; and moreover, wound veneer rolls can be scattered and thentidied again.

Description

technical field [0001] The invention relates to the field of automation equipment, in particular to a retractable winding device and a use method thereof. Background technique [0002] Wood veneer is a decorative material used for direct cladding of cabinets, furniture, wooden doors, etc., and is generally used for edge banding and decoration. The thickness of the veneer is generally less than 0.5mm, and the length of the veneer wound in a roll of veneer is very long, so it is very easy to have the problem of uneven upper ends of the veneer roll after the production is completed, resulting in multiple stacks of veneer rolls There may be problems with unstable placement when stacked. In particular, the part near the outside of a roll of veneer is more likely to have uneven upper ends. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a winding device for winding veneer, which can also unwind the roll...
