Finger joint finger tenon comb machine

Abstract

The invention discloses a finger-tenon combing machine of a finger-joint material. The finger-tenon combing machine is characterized in that a movable sliding rail is arranged on a combing machine tool body; a pressing clamping plate is supported on a movable platform frame by a pressing cylinder; the pressing clamping plate and a feeding platform surface form a material clamping jaw for clamping wood materials to be combed; one side of the material clamping jaw is provided with a side pressing plate; the movable platform frame is also provided with a towing gear driven by a motor of a movable working platform; the towing gear is in meshed transmission with the towing gear; a tooth-tenon combing and milling device is also provided with an upper wire-groove saw blade and a lower wire-groove saw blade; the horizontal plane of a saw shaft for cutting the saw blades is positioned between the horizontal plane of a saw shaft of the upper wire-groove saw blade and the horizontal plane of a saw shaft of the lower wire-groove saw blade; the tooth-tenon combing and milling device is also provided with a neat-end control sensor; the movable clamping working platform is provided with a feeding control sensor. The finger-tenon combing machine disclosed by the invention has the advantages that the processing accuracy and the wood-material utilization rate are high, the processing quality of the surfaces of the wood materials is excellent, and the whole-machine operation efficiency is high.

Description

technical field [0001] The invention relates to a production equipment for finger-jointed gauge timber, in particular to a machine for processing fingers and mortise teeth of finger-jointed timber. Background technique [0002] Timber, as an important means of production and living for human beings, is facing a severe shortage of resources. Therefore, the utilization of wood must adopt a sustainable development mode of production; finger-jointed timber production is an effective way to save resources. Finger-jointed materials are small materials and leftover materials that are combed and milled at both ends, and then finger-joined to make integrated specification materials, realizing the effects of short materials for long use, small materials for large use, and inferior materials for optimal use , improve the wood utilization rate and product grade rate, and play a significant role in alleviating the shortage of wood resources, especially high-quality wood resources, so it ...

AI Technical Summary

Problems solved by technology

There are some outstanding defects in the existing comb technology and comb equipment: one is the single-stage table top feeding structure. In the actual feeding process, the front positions of several parallel feeding wooden bars are actually uneven. The horizontal crushing circular saw blade must cut more wood ends before they can be fully sawed, resulting in a waste of wood resources again; the second is that the horizontal crushing circular saw blade directly saws the ends of the wood strips, Wood fiber tearing, fluffing and chipping are very easy to occur on the surface of wood sawed by a tool. On the one hand, the processing precision of the tenon teeth is not high, resulting in a low degree of tightness of the tenon joint, which in turn affects the final mechanical strength and quality of the standard lumber. ; On the other hand, two adjacent wood strips are uneven and not firm after finger-joining, and the amount of planing after finger-joining is relatively large, which greatly reduces the utilization rate of wood; the third is that in this structure, the feed wood Each batch of slats may form mutual feeding interference, which will affect the sawing quality of slats and the accuracy of comb teeth, or the phenomenon of insufficient material supply such as lack of material, resulting in an uncertain supply of slats per batch, affecting the efficiency of comb teeth
