Dual-steel-belt continuous flat press

Abstract

The invention discloses a dual-steel-belt continuous flat press, comprising a rack, a fixed frame arranged on the rack, a moving frame arranged above the fixed frame and a moving frame hydraulic cylinder for controlling the moving frame to move up and down, wherein an upper rolling needle chain blanket and a lower rolling needle chain blanket are respectively driven through an upper carrier roller and a lower carrier roller which are rotationally arranged on the rack, and heating and pre-pressing devices are arranged behind two front rollers and before inlets of an upper hot pressing plate and a lower hot pressing plate. The dual-steel-belt continuous flat press disclosed by the invention is reasonable in design, and plate blanks are heated and pre-pressed in advance, so that the difficulty in manufacturing the dual-steel-belt continuous flat press is reduced sufficiently and the production efficiency is increased; a conveyor belt and the rolling needle chain blankets cannot deviate in a driving process, so that the effect on pressing the plate blanket is enhanced, and the service life of the conveyor belt and the rolling needle chain blankets is prolonged; the plat blankets are consistent in thickness after being pressed so that the quality of a particle board is improved; and even when chains are asynchronous or resistance is nonuniform, chain pinned shafts cannot be damaged if one or some rolling needles in the rolling needle chain blankets deviates / deviate.

Description

technical field [0001] The invention relates to a particleboard production and manufacturing equipment, in particular to a double-steel-belt continuous flat press. Background technique [0002] Oriented particle board is a board made by cutting log materials into wood chips, drying, sizing, directional paving, hot pressing and cutting, etc. This kind of particle board is widely used in construction, decoration, home furnishing, packaging and other fields. The double-steel-belt continuous flat press that is generally used now has the following defects or deficiencies in the process of hot-pressing the slab: (1) When the slab enters the double-steel-belt continuous flat press, in order to make the slab sharply compressed to The thickness meets the requirements. The pressure at the entrance of the double-steel-belt continuous flat press is the part with the highest pressure in the entire continuous press, so the frame and hydraulic cylinder at the entrance of the double-steel ...

AI Technical Summary

Problems solved by technology

The double-steel-belt continuous flat press that is generally used now has the following defects or deficiencies in the process of hot-pressing the slab: (1) When the slab enters the double-steel-belt continuous flat press, in order to make the slab sharply compressed to The thickness meets the requirements. The pressure at the entrance of the double-steel belt continuous flat press is the most pressured part of the entire continuous press, so the frame and hydraulic cylinder at the entrance of the double-steel continuous flat press are also the largest in the entire continuous press. , the most parts, which also increases the manufacturing difficulty of the press accordingly, and reduces the production efficiency; It not only affects the pressing effect, but also makes the conveyor belt (steel belt) and needle chain blanket easy to be damaged; (3) The thickness of the slab after pressing is inconsistent, which affects the quality of the particleboard; (4) The left and right chains are out of sync or the resistance is uneven One or several needles in the needle chain blanket are easily deflected, and in severe cases, the pin shaft of the chain is damaged.
