Description

Technical Field

[0001] This utility model relates to a fixed conveyor reciprocating belt grinder that can continuously grind the surface of a workpiece by changing the moving direction of the conveyor bed, belonging to the field of belt grinder manufacturing. Background Technology

[0002] Belt grinding machines are widely used in metal processing due to their high efficiency. Different abrasive belts and grinding methods can be used depending on the processing requirements of the metal parts, such as deburring, chamfering, polishing, and wire drawing. For most workpieces, the processing requirements can be met in a single pass using a belt grinding machine.

[0003] However, when faced with workpieces that require special processing, if one grinding operation cannot meet the processing requirements of the workpiece, it is necessary to repeat the processing two or even more times. At this time, traditional belt grinding machines cannot meet the requirements of continuous processing. In order to complete the processing requirements, it is necessary to manually move the workpiece and repeat the previous processing steps, which greatly affects the processing efficiency. Summary of the Invention

[0004] Design objective: To overcome the shortcomings of the prior art, and to design a fixed conveyor reciprocating belt grinder that can continuously grind the surface of a workpiece simply by changing the direction of movement of the conveyor bed.

[0005] Design Scheme: To achieve the above design objectives, this utility model incorporates the following design: Based on existing belt grinders, limit switches are installed at the feed inlet and discharge outlet of the belt grinder. These limit switches control the forward or reverse rotation of the drive conveyor motor, thereby causing the workpiece on the conveyor bed to be moved forward and backward multiple times for grinding until the desired state is achieved.

[0006] Technical solution: A fixed conveyor reciprocating belt grinding machine includes a conveyor bed, a frame, a head, and a control panel. Limit switches are installed at the feed inlet and discharge outlet of the frame, wherein the power supply line of the limit switch at the feed inlet is connected to the forward rotation terminal of the motor, and the power supply line of the limit switch at the discharge outlet is connected to the reverse rotation terminal of the motor.

[0007] Compared with the prior art, this utility model achieves continuous reciprocating grinding of the workpiece surface, which greatly improves grinding efficiency and significantly reduces the labor intensity of operators. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of a fixed conveyor type reciprocating belt grinding machine. Detailed Implementation

[0009] Example 1: Refer to Appendix Figure 1 A fixed-conveyor reciprocating belt grinder includes a conveyor bed 1, a frame 3, a head 4, and a control panel 5. The design and manufacture of these components are existing technologies and will not be described here. Limit switches 2 are installed at the feed inlet and discharge outlet of the frame 3. The power supply line of the limit switch 2 at the feed inlet is connected to the forward rotation terminal of the motor, and the power supply line of the limit switch 2 at the discharge outlet is connected to the reverse rotation terminal of the motor. The use of limit switches 2 to control the forward or reverse rotation of the motor is existing technology and will not be described here.

[0010] The technical means to achieve reciprocating grinding of the workpiece is as follows: When the workpiece is being ground on the conveyor bed 1 and passes through the belt grinding head in the forward direction, if the workpiece encounters the limit switch 2 located at the discharge port during the output process, the motor driving the conveyor bed to move forward immediately rotates in the reverse direction. This causes the conveyor bed to move in the reverse direction and pass through the belt grinding head for secondary grinding. Then, if the workpiece encounters the limit switch 2 located at the feed port during the reverse output process, the motor driving the conveyor bed to move forward immediately rotates in the forward direction. This causes the conveyor bed to move in the forward direction and pass through the belt grinding head for further grinding, and so on, until the grinding meets the requirements. The adjustment of the abrasive amount of the belt grinding head can be done manually or automatically through parameters input in the control panel 5, which refers to the PLC control panel.

[0011] It should be understood that although the above embodiments provide a relatively detailed textual description of the design concept of this utility model, these textual descriptions are merely simple textual descriptions of the design concept of this utility model, and not limitations on the design concept of this utility model. Any combination, addition, or modification that does not exceed the design concept of this utility model shall fall within the protection scope of this utility model.
