Problems solved by technology

[0003] Due to the large size of the movable platen of the veneer press and the existence of eccentric loads, the movable platen will be inclined during its pressurization and movement. At this time, it is impossible to ensure an evenly distributed pressing pressure, which is caused by the unbalanced movement of the platen The consequence is: the pressing is not uniform, the defective rate of the plate after pressing is high, and the production cost is greatly increased

Embodiment 1

[0033] See figure 1 with figure 2 , the pressure plate motion balance detection device of the present embodiment includes an oil cylinder assembly 1, a pressurization solenoid valve 2, a pressure relief solenoid valve 3, a pressure sensor 4, a pressurization pressure limit valve 5, a safety valve 6, an oil inlet pipe 7 and an oil outlet pipe 8 .

[0034] The oil cylinder assembly 1 is provided with two groups. The cylinder assembly 1 includes a first double-rod cylinder 1-1 and a second double-rod cylinder 1-2. The cylinder blocks of the two first double-rod cylinders 1-1 and the two second double-rod cylinders 1-2 are fixed relative to the ground. The bottoms of the piston rods in the lower cavity of the two first double-rod cylinders 1-1 and the two second double-rod cylinders 1-2 are respectively installed on the four corners of the movable platen 9, and the first cylinder assembly 1 of each group One pair of rod-out cylinders 1-1 and the second double-rod cylinder 1-2...

Embodiment 2

[0047] This embodiment is basically the same as Embodiment 1, the difference is that only one group is provided for the cylinder assembly 1, and the bottoms of the piston rods in the lower cavity of the first double-rod cylinder 1-1 and the second double-rod cylinder 1-2 are respectively It is installed on one group of diagonal corners of movable platen 9.

Abstract

The invention discloses a pressing plate motion balance detection device and a detection method thereof. According to the pressing plate motion balance detection device, the upper cavity and lower cavity of each first double-outgoing rod oil cylinder are communicated with an oil feeding pipe through two oil feeding pipelines respectively; the two oil feeding pipelines are both provided with oil feeding one-way valves; the upper cavity and lower cavity of each second double-outgoing rod oil cylinder are communicated with the oil feeding pipelines of the upper cavity and lower cavity of the first double-outgoing rod oil cylinder; the oil feeding pipelines of the upper cavity and lower cavity of the first double-outgoing rod oil cylinder are communicated with the inlet of an oil outgoing pipethrough two oil outgoing pipelines respectively; the inlets of the oil outgoing pipelines are located at the outlet sides of the oil feeding one-way valves; the two oil outgoing pipelines are both provided with oil outgoing one-way valves; a pressurization solenoid valve and a de-pressurization solenoid valve are respectively disposed on the oil feeding pipe and the oil outgoing pipe; and a pressure sensor is communicated with the oil outgoing pipe at the inlet side of the de-pressurization solenoid valve through a detection oil pipe. The device and method of the invention have the advantagesof ingenious structure, low construction cost and high detection precision. With the device and detection adopted, the balance of the movement of a moving pressing plate can be ensured, and the defective rate of a finished pressing plate can be greatly reduced.

Description

technical field [0001] The invention relates to a detection device and a detection method for the movement balance of a pressing plate. Background technique [0002] Pressing is also called veneering process. Pressing is an important process in the production process of impregnated paper laminated wood flooring. The veneer press requires high processing precision and strict control of process parameters, otherwise it will cause serious damage to product quality. influences. [0003] Due to the large size of the movable platen of the veneer press and the existence of eccentric loads, the movable platen will be inclined during its pressurization and movement. At this time, it is impossible to ensure an evenly distributed pressing pressure, which is caused by the unbalanced movement of the platen. The consequence is that the pressing is uneven, the defective rate of the plate after pressing is high, and the production cost is greatly increased. Therefore, it is necessary to d...
