Hydraulic control system for constant pressure press for timber floor

Abstract

The invention discloses a hydraulic control system for a constant pressure press for a timber floor. The hydraulic control system for the constant pressure press for the timber floor comprises a mechanical mechanism and a hydraulic mechanism; a proportional control amplifier (16) of the hydraulic mechanism comprises an input interface unit (18) connected with a pressure sensor (17); the input interface unit (18) is connected with a signal processing unit (19) connected with a power amplifying unit (20); the power amplifying unit (20) is connected with a proportional speed regulation valve (15) provided with a displacement sensor (21); the displacement sensor (21) is connected with a signal conditioning circuit (22); the signal conditioning circuit (22) is connected with the signal processing unit (19). Multiple timber floor manufacturing procedures are integrated, so the manufacturing process is greatly simplified, the production efficiency is improved and manpower is saved; the hydraulic control system can be industrially produced, so the product consistency can be ensured.

Description

technical field [0001] The invention relates to a hydraulic control system for a wood floor constant pressure press, belonging to the field of wood machinery. Background technique [0002] Wood flooring is an indispensable home improvement material in home decoration. With the continuous improvement of living standards, consumers have higher and higher requirements for flooring. Existing wood floors are mainly divided into solid wood floors, solid wood composite floors and laminate floors. These three kinds of wood floors generally include veneer, core board and balance layer from top to bottom. The production process of existing wood floors is divided into multiple layers. In the process, the two sides of the blank board are first processed to obtain a tongue and groove, and then the skin is pasted on the surface of the blank board and hot-pressed, and then the balance paper is pasted on the bottom surface of the blank board and hot-pressed. Therefore, the production of the...

Existing wood flooring is mainly divided into solid wood flooring, solid wood composite flooring and laminate flooring. These three types of wood flooring generally include veneer, core board and balance layer from top to bottom. The existing wood flooring manufacturing process is divided into multiple In the process, the two sides of the slab are first processed to obtain grooves, and then the skin is attached to the surface of the slab and hot-pressed, and then the balance paper is attached to the bottom of the slab and hot-pressed, so the production of the existing wooden floor The process is not only cumbersome, the production efficiency is not high, and it is a waste of manpower, but also generally manual operation, which cannot guarantee product uniformity

At present, the industry is researching a system that realizes a constant pressure floor by controlling the feedback control of the hydraulic mechanism and the motor and other mechanical mechanisms of the pressing speed of the upper cylinder, but the current research on the hydraulic mechanism is relatively immature, so the existing The hydraulic mechanism has become an urgent problem to be solved in this field
