Abstract: A roll forming device for plastic flooring utilizes a printed layer unwinding mechanism, a wear-resisting unwinding mechanism and a calender to laminate a substrate layer formed by an extruder, a printed layer and a wear-resisting layer into a whole. The calender includes a gauging roller group, a pre-bonding roller group and a laminating roller group disposed on a rack. The gauging roller group, which is disposed at one side of the pre-bonding roller group and linearly opposite to a discharge port of the extruder. The pre-bonding roller group includes a large roller and a plurality of guide rollers disposed around the large roller, and at least one first heating unit is disposed in the large roller or a position corresponding to an outer edge of the roller surface. The laminating roller group, which is disposed at the other side of the pre-bonding roller group.

Abstract: Provided in the present disclosure are a voice processing method, an apparatus, an electronic device, and a storage medium, the method comprising: detecting the working state of a current call system, and when the working state is a two-end speaking state or a remote-end speaking state, performing compression processing on a subsequent remote-end voice signal, acquiring a near-end voice signal by means of a microphone, performing echo processing on the basis of the near-end voice signal and the compression-processed remote-end voice signal to obtain an echo-processed near-end voice signal and a remaining echo signal, performing non-linear suppression processing on the near-end voice signal and the remaining echo signal, and performing gain control on the suppression-processed near-end voice signal.

Abstract: The present invention relates to a movable laminator and a plastic flooring laminating device applied by same. A laminating mechanism, a driving mechanism and a conveying mechanism assembled on a rack compose the laminator which can make continuous reciprocating movements. The movable laminator is then disposed in an automatic production line for plastic flooring to cooperate with an extruder, a rolling unit and a drawing mechanism to laminate a plastic flooring material composed of a substrate layer, a printed layer and a wear-resisting layer into a finished plastic flooring product in an automatic operation manner. Because the time of the lamination of the material by the movable laminator can match the speed at which the material is conveyed and moved, the laminating mechanism is driven by the second power source to move from the front section position to the rear section position on the rack.
