Last feeding roller and following feeding roller can adopt identical material make, as materials such as iron, copper, stainless steel and other metal materials or rubber, being preferably feeding roller is iron roll, is used to guarantee that workpiece is smooth transports, and is difficult for being damaged by workpiece; Feeding roller down on the other side is a rubber roll, can effectively eliminate workpiece 2mm with interior thickness error, has strengthened adaptability of the present utility model.The last feeding roller of metal quality and the following feeding roller of colloid are used, overcome the feeding roller of simple metal quality, when processing the incomplete workpiece of thickness at the same time, the drawback of compatibility difference and the easy hurricane material of thin slice workpiece has also overcome the not steady and flimsy drawback of pure colloid feeding roller holding workpiece.
Influence the effect of sanding for the gathering that reduces the chip in the polishing process, preferably also be provided with air exhauster on the described frame, and the suction opeing of air exhauster is sent the chip that produces in the sanding process outside the machine timely with assurance between last sanding roller and following sanding roller.
The utility model compared with prior art has following advantage:
1, to the sanding of workpiece, can select once one side, a two sides, can also select the sanding precision by selecting different sanding rollers, sanding is effective, effect is high;
2, can carry out the sanding operation to the workpiece of many groups material, Workpiece length is not limit, and width can reach 22cm, and thickness is in 2mm~100mm, just can operate as normal and do not damage machinery;
3, simple in structure, realize easily that it is nearly 1/3rd to save cost than like product, stable performance, fault rate is low, long service life, accessory is simple and easy to, and it is convenient to keep in repair.
