Equipment for automatically detecting hardness and polishing degree in plywood production

Abstract

The invention belongs to the technical field of plywood, in particular to equipment for automatically detecting hardness and polishing degree in plywood production. The lower surface of a placement plate is rotationally connected with a polishing head; the outer surface of the placement plate is fixedly connected with a mounting base; a supporting seat is fixedly connected inside the mounting base; a detection rod is connected inside the supporting seat in a sliding way; the lower end of the detection rod is fixedly connected with an extrusion base; first rotating rods are rotationally connected to the left end and the right end of the supporting seat; one ends of the first rotating rods are rotationally connected with second rotating rods inside the extrusion base; the surface of the supporting seat is movably connected with telescopic rods on the upper surfaces of the second rotating rods; and the outer surfaces of the telescopic columns are sleeved with telescopic springs. When theequipment is in use, the pressure on plywood can be detected automatically in order to determine the hardness of the plywood, and the qualification of the plywood can be detected to eliminate certainhollow plates.

Description

technical field [0001] The invention belongs to the technical field of plywood, and in particular relates to a device for automatically detecting hardness and grinding degree used in plywood production. Background technique [0002] Plywood is a three-layer or multi-layer board-like material that is made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered veneers are used, and adjacent layers of veneers are used. The fiber directions are glued perpendicular to each other. Plywood is one of the commonly used materials for furniture, and it is one of the three major boards of wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneers are usually glued together according to the direction of the wood grain of the adjacent layers perpendicular to each other. Usually, the surface board and the inner layer board are symmetrically arrang...

AI Technical Summary

Problems solved by technology

[0003] In the production process of plywood, it is often necessary to cut to determine different plywood. After cutting, there are often a lot of burrs on the surface of both sides of the plywood, and it is generally more troublesome when dealing with some arc edge burrs, and it is also a problem for the staff. Self-test the degree of grinding, and at the same time, the plywood produced cannot be tested for pressure during the production process. If there are some hollow plates, it is generally difficult to detect intuitively. Therefore, in view of this, for the existing structure And the lack of research and improvement, to provide an automatic detection of hardness and grinding degree equipment for plywood production, in order to achieve more practical value
