The anti-slip design helps to improve the conveying stability of the workpiece and prevent the workpiece from shifting or being thrown away.

[0050] The polishing mechanism includes a polishing mounting base 4, which spans laterally across the conveyor. Both sides of the polishing mounting base 4 are supported on the sliding plate 5 by bolts and nuts. The support height of the polishing mounting base 4 can be adjusted to change the gap between the polishing head 10 and the conveyor, thus adapting to polishing operations of workpieces of different thicknesses.

[0051] A slide rail 6 is provided on the conveyor along the transverse direction. The sliding plate 5 slides with the slide rail 6 through a slider. The connection between the slider and the slide rail 6 is simple and reliable. A transverse motion force assembly is provided on the conveyor. The transverse motion force assembly includes a transverse drive motor 7 installed on the conveyor. The transverse drive motor 7 is installed on the conveyor through a transverse support. The output shaft of the transverse drive motor 7 drives the crank to rotate. The crank is connected to the polishing mounting seat 4 through a connecting rod 8. The transverse drive motor 7 provides power and drives the polishing mounting seat 4 to move back and forth through the crank and connecting rod 8. The structure is simple and reliable, realizing the movement of the polishing head 10 in the transverse direction.

[0052] Five polishing head supports 9 are spaced apart below the polishing mounting base 4, arranged in two rows. Three supports are located near the beginning of the conveyor, and two are located near the end. The two rows of polishing head supports 9 are staggered in the front-to-back direction. Horizontally arranged polishing heads 10 (rotary polishing rollers for polishing workpieces) are positioned on both sides of the bottom of the polishing head supports 9. The two polishing heads 10 are driven to rotate by a self-rotating power component mounted on the polishing mounting base 4, while the polishing head supports 9 are driven to rotate by a revolution power component mounted on the polishing mounting base 4.

The drive sprocket and five driven sprockets are driven and coupled via a self-rotating chain 12. A drive bevel gear is mounted at the bottom of the transmission shaft. A self-rotating shaft, which engages with the drive bevel gear, is located at the bottom of the polishing head bracket 9. Two polishing heads 10 are mounted at opposite ends of the self-rotating shaft. The self-rotating drive motor 11 provides power, achieving simultaneous drive through chain transmission, rotating several polishing heads 10. This improves polishing uniformity and quality.

The revolution drive motor 13 provides power, achieving simultaneous drive through chain transmission, rotating several polishing head brackets 9, which helps improve polishing uniformity and quality.

[0055] Two brush rollers 15 are spaced apart on the conveyor, located near the end of the conveyor. The brush rollers 15 are supported by brush roller support seats 16, which are connected to the conveyor via bolts and nuts. This bolt and nut connection allows adjustment of the distance between the brush roller support seats 16 and the conveyor, thereby adjusting the distance between the brush rollers 15 and the conveyor, providing adaptability. The brush rollers 15 are driven to rotate by a brush roller drive assembly mounted on the conveyor. The brush roller drive assembly includes a brush roller drive motor 17, located below the two brush rollers 15. The motor provides power, driving the two brush rollers 15 to rotate via chain drive. Because brush rollers are located at the end of the conveyor, after the workpiece is conveyed to the end, the brush rollers 15 can perform polishing and brushing again, improving polishing accuracy and quality.

[0056] Multiple pressure roller assemblies are installed on the conveyor to press the workpieces on the conveyor.

[0057] The pressure roller assembly includes a pressure roller 18, with roller shafts at both ends of the pressure roller 18 rotatably mounted at the bottom of a pressure adjusting rod 19.

A preload spring 21 is sleeved on the pressure adjusting rod 19 and abuts against the pressure support 20. The pressure support 20 has a long slot 22, which is opened vertically. The roller shafts at both ends of the pressure roller 18 are located within the long slot 22. The long slot 22 guides the pressure roller 18, and the preload spring 21 maintains a certain clamping force on the pressure roller 18.

[0058] Pressure roller assemblies are provided on both the front and rear sides of the polishing head 10 and the brush roller 15 to prevent workpiece displacement or being thrown away.

[0059] The polishing machine is also equipped with a dust removal component, which includes a dust removal cover 23 mounted above the conveyor. The dust removal cover 23 is supported on the conveyor by a dust removal bracket 24 and is enclosed on all four sides to prevent dust from escaping and causing environmental pollution during polishing operations. The dust removal cover 23 has several dust removal ports 25 located above the polishing mechanism. These ports can directly suck up dust or be connected to external dust collection equipment. Several dust removal connection ports 26 are provided on the polishing mounting base 4 for connecting dust removal pipes to the dust removal ports 25. Through the dust removal component, dust removal can be achieved, sucking up the dust generated during workpiece polishing and reducing environmental pollution.

[0060] The conveyor system is used to move the workpiece, and the polishing head 10 is mounted on the polishing mounting base 4. The self-rotation power component drives the workpiece to rotate and polish it, while the revolution power component drives the polishing head bracket 9 to rotate, thereby driving the polishing head 10 to revolve, improving the polishing efficiency of the polishing head 10, avoiding polishing in the same position, and improving polishing uniformity. The lateral movement power component drives the polishing mounting base 4 to move laterally along the conveyor, thereby driving the polishing head 10 to move laterally, which helps to increase the polishing area and improve the workpiece polishing efficiency and quality. The pressure roller assembly can press the workpiece firmly onto the conveyor, preventing the workpiece from shifting or flying during the polishing process, thus improving polishing quality and efficiency.
