Description

Technical Field

[0001] This utility model relates to the field of belt grinding technology, and more specifically, to belt grinding machines. Background Technology

[0002] A belt grinder is a type of grinding machine that uses an abrasive belt as the grinding tool. It is widely used in surface grinding, polishing, and deburring of both metallic and non-metallic materials. Belt grinders offer advantages such as high grinding efficiency, wide applicability, and flexible operation.

[0003] In existing belt grinders, a workpiece support plate is usually installed at the front of the machine frame for workpiece grinding. However, the use of a plate-like support structure makes it difficult to adjust the grinding angle when the workpiece is being ground by the belt. Furthermore, friction can easily occur between the workpiece and the support plate when the workpiece moves back and forth, affecting the ease and flexibility of workpiece movement during grinding. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a belt grinder to solve the technical problems mentioned in the background art, such as the inconvenience of flexibly adjusting the grinding angle when the workpiece is placed for grinding, and the large friction when the workpiece moves.

A second support roller is provided at the tail end of the connecting frame via a bearing. The second support roller can cooperate with the first support roller to improve the support effect of the workpiece when it is being ground by the grinding belt.

[0009] The present invention is further configured such that the mounting frame has an adjustment groove, the connecting frame has an adjustment column, the adjustment column extends outward through the adjustment groove and is threaded with a locking knob, loosening or tightening the locking knob allows the adjustment column to rotate within the adjustment groove, and the support position of the second support roller can be flexibly adjusted by adjusting the installation angle of the connecting frame, and after adjusting to a suitable position, tightening the locking knob locks the adjustment column in the adjustment groove, thereby achieving the installation and fixation of the second support roller.

[0010] The present invention is further configured such that a first dust suction hood is provided at the bottom of the mounting bracket, a second dust suction hood is provided on the side of the first fixed bracket, and a vacuum cleaner is connected to the tail ends of the first and second dust suction hoods. Under the action of the vacuum cleaner, the dust and debris generated during workpiece grinding can be absorbed through the cooperation of the first and second dust suction hoods, thereby improving the cleanliness of workpiece grinding.

[0011] The present invention is further configured such that a fixed seat is installed on the second fixed frame, and a telescopic seat is installed on the first fixed frame. The tail end of the telescopic seat is slidably and telescopically located inside the fixed seat.

Beneficial effects

[0015] Compared with the prior art, the present invention provides a belt grinding machine, which has the following beneficial effects:

[0016] 1. In this utility model, a first support roller is installed in front of the grinding belt via a mounting frame. In this way, when processing the workpiece, the section of the workpiece to be ground can be placed on the first support roller, thereby supporting one end of the workpiece. By holding the other end of the workpiece, the workpiece can be moved flexibly, and the support angle of the workpiece can be adjusted flexibly, thus improving the grinding flexibility.

[0017] 2. Furthermore, the use of a roller-type first support roller can provide support while changing sliding friction to rolling friction during workpiece movement. This reduces the frictional force on the workpiece before and after grinding, thereby improving the workpiece's movement flexibility during grinding.

[0018] 3. In this invention, a second support roller is connected to the outside of the first support roller via a connecting frame, and the connecting frame is rotatably and adjustablely mounted on the mounting frame. This allows the second support roller to cooperate with the first support roller to improve support performance. At the same time, the installation position of the second support roller can be flexibly adjusted by adjusting the installation angle of the connecting frame on the mounting frame. This allows for flexible adjustment of the support angle between the support surfaces formed between the first and second support rollers, improving the flexibility of support when the workpiece is being ground by a grinding belt. Here, the first support roller can be used alone or in conjunction with the second support roller. Attached Figure Description

By holding the other end of the workpiece, the workpiece can be moved flexibly, and the support angle of the workpiece can be adjusted flexibly, thus improving the grinding flexibility.

[0039] Furthermore, the first support roller 12 is designed as a roller, which can support the workpiece while changing sliding friction to rolling friction during workpiece movement. This reduces the friction of the workpiece before and after grinding, thereby improving the workpiece's movement flexibility during grinding.

[0040] This invention features a second support roller 14 connected to the outer side of the first support roller 12 via a connecting frame 13. The connecting frame 13 is rotatably and adjustablely mounted on the mounting frame 11.
