Double-end finger joint laminated board tenoning machine

Abstract

The invention relates to the technical field of wood processing devices and particularly relates to a double-end finger joint laminated board tenoning machine. The double-end finger joint laminated board tenoning machine comprises a machine base, a feeding frame and a tenoning device, wherein the feeding frame is capable of doing reciprocating motion on the machine base through a transmission chain; the feeding frame is used for fixing wood boards; the tenoning device comprises placing boxes; two placing boxes are respectively located at two sides of the machine base and are connected with each other through a telescopic device; a trimming saw blade, a tenoning blade and a roughness removing hairbrush are arranged on each placing box; an aligning device is capable of aligning wood boards before tenoning. According to the double-end finger joint laminated board tenoning machine, a PLC is used as a control system; the tenoning machine has higher flexibility and is capable of tenoning long wood boards and the wood boards of various lengths and reducing roughness of tenoned grooves; the tenoning machine is automatically controlled, so that the occurrence of the safety accidents is avoided.

Description

technical field [0001] The invention relates to the technical field of wood processing devices, in particular to a double-headed finger-jointed board tenoning machine. Background technique [0002] The tenon and groove processing of the finger joint board is to first align and clamp one end of the side-by-side wooden strips, and then push the cogged wheel saw group along the guide rail to saw the end faces of the entire row of wooden strips into the tenon and groove in batches. In order to ensure the interchangeability of the mortise and groove sizes cut out by sawing, before the ends are aligned and pushed into the cogged wheel saw group, the unevenness of the ends should be sawed off with a trimming circular saw to ensure that the ends are flush before sawing tongue and groove. Although there are many structural forms of finger-jointed board tenoning machines, the basic structural forms are generally similar. [0003] Current finger-jointed board tenoning machines have t...

AI Technical Summary

Problems solved by technology

[0004] 1) The flexibility is low. When the board to be tenoned is long, it needs to be cut before being placed in the tenoning machine for tenoning, which is inefficient and consumes manpower and materials;

[0005] 2) After the wooden boards are tenoned, roughness will appear on the tenon and groove, which will lead to unstable joints of the finger-jointed boards during jointing, and will affect the appearance;

[0006] 3) A large amount of sawdust will be produced during tenoning, which will have a serious impact on the working environment and will endanger the health of the staff
