Description

Technical Field

[0001] The utility model belongs to the technical field of pre-pressing machines, and in particular relates to a pre-pressing machine for preventing hand pressure. Background Art

[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesive. It is usually made of an odd number of veneers, with the fibers of adjacent veneers glued perpendicular to each other.

[0003] Plywood is one of the commonly used materials for furniture and one of the three major artificial boards. It can also be used as a material for airplanes, ships, trains, cars, buildings and packaging boxes. A group of veneers are usually assembled and glued in the direction of the wood grain of adjacent layers perpendicular to each other. Usually, the surface board and the inner layer are symmetrically arranged on both sides of the center layer or the core. The slabs are made by crisscrossing the veneers coated with glue in the direction of the wood grain, and pressed under heating or non-heating conditions;

[0004] The pre-press is an auxiliary machine of the plywood production line. It is a mechanical equipment for preliminary bonding before gluing in order to shorten the hot pressing cycle and improve the quality of the board. The pre-press belongs to a pressure machine.

[0005] "202020183689.7" discloses a pre-pressing machine, which can only pre-press one board at a time, so that the pre-pressing machine needs to frequently replace the board, which makes the pre-pressing efficiency of the pre-pressing machine for plywood low. Utility Model Content
