Description

TECHNICAL FIELD

[0001] The utility model relates to plywood processing field, concretely is a kind of hot press for processing plywood. BACKGROUND

[0002] Plywood is one of furniture commonly used materials, is one of three big boards of artificial board, also can be used for airplane, ship, train, car, building and packaging box etc. function material. A group of veneers is usually assembled and glued according to the perpendicular direction of adjacent layer wood grain, and the veneer and the inner layer board are symmetrically arranged on the two sides of the center layer or board core. Plywood can improve the utilization rate of wood, which is a major way to save wood. During processing, hot pressing is required. Hot pressing can make the adhesion between board blanks more compact, and also release the formaldehyde in glue faster at high temperature, thereby reducing the formaldehyde content of the processed plywood.

[0003] The current hot press for processing plywood, as described in the patent with announcement number CN209579861U, includes moving wheels, a placing frame, placing plates, plywood, tension springs, lifting hydraulic cylinders, lifting plates, rollers, transmission rods, limit blocks, hot pressing plates, moving grooves, rollers, air grooves and air holes. The moving wheels are installed below the placing frame, and several placing plates are installed on the placing frame. The adjacent placing plates are connected by tension springs. The topmost placing plate is connected to the top of the placing frame by a tension spring. The plywood is placed on the placing plates. The placing frame leads to the hot press, which includes lifting hydraulic cylinders, lifting plates, rollers, transmission rods, limit blocks and hot pressing plates. The lifting hydraulic cylinders are located outside the hot press, and the lifting plates are fixedly installed on the lifting hydraulic cylinders. The moving grooves are opened on the lifting plates.

[0004] According to the related technology in the above, the inventor believes that since the rollers are connected to the transmission rods through the rollers, and the transmission rods are sequentially connected, each group of hot pressing plates can move up and down at equal intervals. When the twisted plates need to be placed, the distance between each group of hot pressing plates needs to be adjusted to the maximum, which causes the top hot pressing plate to be adjusted to a higher position. At this time, the top placing plate on the placing frame needs to be set higher, which causes the worker to place the twisted plates on the top placing plate on the placing frame to need to lift the twisted plates to a higher position, which causes the placement of the twisted plates to be more laborious, and further causes the labor intensity of the worker to be larger.
