The use of abrasive belt machining has the advantages of high production efficiency and high product qualification rate; thus it is widely used in various fields, especially in hardware, plumbing and furniture industries.

There are many types of belt machines, such as a flat abrasive belt polishing machine proposed by the applicant [application number: 200610118511.9; authorized announcement number: CN1962191B], which includes a frame with a workbench, which is equipped with a The supporting shaft connected to the mechanism, the driving wheel is connected to the supporting shaft, the driven wheel and the tensioning wheel are also arranged on the frame, and the driving wheel, the driven wheel and the tensioning wheel are sleeved with abrasive belts. The belt is arranged in parallel with the abrasive belt, and a column is arranged on the frame, and the above-mentioned tensioning wheel is arranged at the column, and a tensioning device capable of moving the tensioning wheel is provided between the tensioning wheel and the column. When using this polishing machine to grind workpieces, the workpieces are fixed on the workbench, the surface to be ground must be a horizontal plane, and the workpiece feed is completed by lifting the workbench.

Another example is a belt changing mechanism for an abrasive belt flat polishing machine proposed by the applicant before [application number: 01254790.5; authorized announcement number: CN2505230Y]. The abrasive belt flat polishing machine is composed of a body, a motor, a driving wheel and a driven wheel. Both the wheel and the driven wheel are fixed on the body and are located on the same horizontal plane. When using this polishing machine to grind a workpiece, the workpiece is held and pressed on the surface of the abrasive belt from top to bottom, thereby completing the fixing and feeding of the workpiece at the same time.

Another example is a kind of vertical abrasive belt grinding machine [application number: 00259206.1; authorized announcement number: CN2449871Y] designed by an applicant from Taiwan, China. Set up a vertical frame, set a tensioning wheel on the upper part of the vertical frame, and set a tension wheel on the top of the vertical frame, set up a group of abrasive belts by two tensioning wheels, and use a protective box to cover and isolate only the abrasive belt below. In the exposed shape, a connecting pipe is set on the top of the protective box to connect the dust collection equipment, and the pulley connected to one end of the lower tensioning wheel cooperates with a transmission belt to connect the motor inside the machine. When using the vertical abrasive belt grinder to grind workpieces, the workpieces are fixed on the storage platform, and the feeding of the workpieces is realized by manipulating the storage platform; the grinding machine uses exposed abrasive belts for grinding. According to the manual, although the vertical abrasive belt grinder can produce automatic correction effect, there are the following defects in the transmission and tension of the abrasive belt. 1. Because the length of the abrasive belt is more, such as 2.2 meters, 2.4 meters, etc.; Obviously, this structure cannot greatly adjust the distance between the two tensioning wheels, that is, the grinding machine cannot be suitable for abrasive belts of different lengths. 2. There are many relationships that need to be adjusted between the two tensioning wheels, such as vertical spacing, horizontal spacing, levelness of the axis, parallelism between the two axes, etc. Some relationships between them cannot be adjusted, and must be guaranteed by ensuring the accuracy of parts and assembly, which increases production costs and is not conducive to subsequent maintenance and adjustment.
