Abstract

The utility model relates to a multi-bistrique automatic plane abrasive belt machine, comprising a bay, a bench on the bay and a commercial plant equipped over the bench. The multi-bistrique automatic plane abrasive belt machine is characterized in that at least two commercial plants are side-by-side equipped above the bench with distance and the commercial plants are provided with a shifter and a buffer pool which make an action wheel and a driven pulley move up-and-down. Therefore when the piece of work is once working, at least two station sanders can be operated. The efficiency is raised and the abrasive belt can not have the problem of crossover twist due to the excessive axial force. Even if the surface is not plan or straight, the good result can still be achieved. The abrasive belt also comprises an automatic feeding delivery mechanism, thereby the operation is easier and the efficiency is raised.

Description

Many bistriques automatic plane belt sander

Technical field

The utility model relates to a kind of woodworking machinery, removes many bistriques automatic plane belt sander of burr and sanding in particularly a kind of sawn timber process.

Background technology

General carpenter work needs again it to be carried out the sanding surface operation after machine-shaping.In the sanding operation, often need just can reach optimum efficiency through the different multiple tracks abrasive band sand milling program of thickness.Yet mostly be single many bistriques of operation automatic plane belt sander on the market, the operator need prepare the automatic plane of bistrique more than many belt sander simultaneously, the abrasive band of different roughness is installed on every many bistriques automatic plane belt sander, or on the belt sander of bistrique automatic plane more than same, change the abrasive band of different roughness, but adopt which kind of mode cost all can improve, operator's working time also will extend.In the technology multiple working procedure many bistriques of multiaxis automatic plane belt sander is together arranged also now, as Chinese patent " sander sand paper the drives device " patent No. is 99200307.5, this kind device mainly by power transmission shaft, be located at the top wheel of board top and be located at the driven wheel of power transmission shaft between taking turns with the top and constitute driving wheel group, wherein on driven wheel, form a plurality of segmental arcs, the intersegmental periphery along driven wheel of adjacent arc is convexly equipped with and forms circular fin, to separate each bar abrasive band, prevent the abrasive band because of be subjected to axial force uneven cause slippage overlap strand around.But this kind device is being made in the processing, except that making the segmental arc by car, need the reprocessing car to make the circular arc fin in addition, whole procedure is quite numerous and diverse, not only increases cost, and maintenance in the future is difficulty also, secondly each abrasive band separates by fin, if the axial force of carpenter work is excessive, the abrasive band also is to have the possibility that produces slippage on thrust, and the abrasive band overlaps to twist around problem and just is difficult to really stop so.

Summary of the invention

The purpose of this utility model is at above-mentioned defective and deficiency, provides a kind of multiple operation of handled easily can not produce the many bistrique automatic plane belt sander of strand around problem that overlap together again.

The technical solution of the utility model is achieved in that
