Hollow extruded plastic board and its processing method

technical field

The invention relates to a hollow extruded plastic board and a processing method thereof.

Background technique

Currently popular furniture on the market is usually made of spliced solid wood panels. Such furniture is not only expensive, but also has a heavy weight, which is inconvenient to carry and assemble. In order to reduce the weight and cost of furniture side panels, a hollow extruded panel has appeared on the market, such as plastic steel plate, wood-plastic panel, etc. The structure of this type of hollow extruded panel is shown in Figure 1, which includes panels at both ends 01 and the vertical ribs 02 arranged in parallel at intervals between the two panels 01, there is a side perforation 03 between two adjacent vertical ribs 02 on the side of the hollow extruded board, and the thickness of the panel 01 is generally small, so it cannot be directly threaded The connection fixes two hollow extruded panels together, so that the hollow extruded panels need to be transitionally connected through other profiles or components when splicing. For example, the Chinese utility model patent with the notification number CN202056753U discloses a combined furniture connecting panel. The connecting plate is a hollow extruded plastic plate. The connecting plate includes panels at both ends and vertical ribs sandwiched between the two panels. Between the two adjacent vertical ribs, there are reinforcing ribs distributed parallel to the panel at intervals. When in use , on the connecting plate at the position of the reinforcing rib, the intermediate connecting piece is fixed through the fixing screw, and the adjacent two wall panels of the furniture are connected together through the intermediate connecting piece, that is, when two adjacent hollow extruded panels are connected , it is necessary to add reinforcing ribs between the two adjacent vertical ribs at the connection position of the hollow extruded board to ensure the reliability of the connection between the two hollow extruded boards, so that during the processing of the hollow extruded board, it is necessary to add reinforcement ribs between the adjacent two vertical ribs Reinforcing ribs are arranged between them, which increases the processing difficulty of the hollow extruded board and reduces the processing efficiency of the hollow extruded board.
