摘要： A grinding machine includes a support and a board which is connected to the connection portion of the support. The board has a first opening and a second opening. A transportation device is connected across over the first and second openings. A grinding device has a driving portion and a grinding portion which is connected to the driving portion. The driving portion is connected to the support so that the grinding portion is located above the transportation device. An angle adjustment device is connected between the board and the transportation device so as to adjust inclination of the transportation device so as to grind a larger area of an object.

摘要： A grinding-band swaying device for a band grinding machine includes a motor pivotally connected with a machine base and driving an endless grinding band around two rollers and forming a fulcrum for swaying, a speed-reducing unit and an eccentric wheel. The speed-reducing unit is positioned under the motor, having a shaft connected with the eccentric wheel. An elastic compressing unit is provided between the speed-reducing unit or the motor and the machine base, and then the eccentric wheel is kept to elastically urge the machine base. When the motor together with the speed-reducing unit rotates the eccentric wheel, the speed-reducing unit, the motor and the roller sway regularly with the fulcrum and then the endless grinding band moves forward and also sways regularly synchronously to perform grinding against a work with grinding angles constantly altered to achieve balanced grinding result.
摘要翻译：用于带磨床的磨带摇摆装置包括与机座枢转连接的马达，并围绕两个滚筒驱动环形研磨带，并形成摆动支点，减速单元和偏心轮。减速单元位于马达下方，具有与偏心轮连接的轴。在减速单元或马达与机座之间设置弹性压缩单元，然后使偏心轮弹性推动机座。当电动机与减速单元一起旋转偏心轮时，减速单元，电动机和滚子与支点规则地摇摆，然后环形研磨带向前移动，并且同步地同步地摆动以对工作进行研磨研磨角度不断变化，实现平衡磨削效果。

摘要： A high-efficiency dust collecting device with two gateways is connected with exits of a cover of a sand grinder and above two sanding belt rollers., composed of a first gateway set and a second gateway set, which are both formed integrally with a metallic panel and provided respectively with a first and a second arc-like panel, a first and a second blocking plate, and two first and two second dust-guiding plates. A first and a second gateway are respectively formed between the arc-like panel and the blocking plate so as to suck in the dust or the wood flour generated while grinding a workpiece. The dust or the wood flour is then sucked further to pass through the exits to the collecting device, favored by the dust-guiding plates.

摘要： An adjustment device for adjusting a level difference between rollers of a roller belt sander includes a base, an eccentric shaft and a restricting knob. The base is fixed on an interior wall edge of a main body corresponding to two ends of a roller. The eccentric shaft inserted pivotally in a penetrating opening of the base has a rear end portion, and a front-end engaging portion formed eccentrically to engage with the roller pivotally. The restricting knob is engaged in a threaded hole of the base to fix the eccentric shaft. Therefore, the adjustment device can be turned to enable the roller positioned at a level for preferable grinding.
