The mobile slider 21 is fixedly connected to the upper base 5. The mobile motor 20 provides the power for the horizontal reciprocating movement of the entire grinding process. The mobile motor 20 drives the mobile synchronous belt 19 to rotate and move through the mobile synchronous wheel 18, so that the mobile slider 21 above moves along the mobile synchronous belt 19, and the mobile slider 21 drives the upper base 5 and the entire grinding module connected thereto to move. The reciprocating movement of the grinding module can be achieved by controlling the forward and reverse rotation of the mobile motor 20.

[0026] A cylinder base plate and a bracket are provided below the cylinder 6. The cylinder 6 is fixed to the upper base 5 through the cylinder base plate and the bracket. The cylinder 6 is fixed on the upper base 5. The telescopic rod is extended or retracted by controlling the cylinder 6 to drive the lower base 8 to rise and fall. When the PVC board is to be polished, it is placed under the lower base 8 for fixation, or placed on the placement plate 22 and the adsorption plate 23. Then, the cylinder 6 is started to adjust the downward pressure distance of the lower base 8 so that the three sets of polishing roller assemblies reach a suitable polishing height to polish the PVC board.

The third grinding roller assembly 16 is located on one side of the first grinding roller assembly 14. Figure 2-4 It can be seen that there is a blind spot when the first grinding roller assembly 14 and the second grinding roller assembly 15 are polished side by side. Therefore, the third guide roller assembly 16 is used at the rear to supplement the polishing of the blind spot so that the area on the PVC board will not be missed during polishing.

[0029] The connecting bearing seat 14a is fixedly connected to the lower base 8. A connecting portion 14e is provided at one end of the grinding roller body 14b.

[0031] The structures of the first grinding roller assembly 14, the second grinding roller assembly 15 and the third grinding roller assembly 16 are exactly the same, except for the positions and connection methods. The driving force for grinding all comes from the first motor 10. When the first motor 10 is started, the driving shaft 12 is driven to rotate by the driving pulley 10a and the driving belt 10b. The driving shaft 12 is supported by the upper bearing seat 11. The upper bearing seat 11 has the same structure as the connecting bearing seat 14a and is connected by internal bearings so that the driving shaft 12 can be supported and rotated by it. There are two upper bearing seats 11, which are divided into two ends of the driving shaft 12. The driving shaft 12 carries a first synchronous wheel 12a, a second synchronous wheel 12b and a double-row synchronous wheel 13. When the driving shaft 12 rotates, the first synchronous wheel 12a, the second synchronous wheel 12b and the double-row synchronous wheel 13 rotate synchronously, thereby driving the first grinding roller assembly 14, the second grinding roller assembly 15 and the third grinding roller assembly 16 to rotate to form a grinding work.

[0032] See also Figure 4One end of the connecting belt 14d of the first grinding roller assembly 14 is connected to the first synchronous wheel 12a, and the other end is connected to the connecting synchronous wheel 14c of the first grinding roller assembly 14, so that the first synchronous wheel 12a can drive the first grinding roller assembly 14 to rotate. The driving method of the second grinding roller assembly 15 and the third grinding roller assembly 16 is also the same. One end of the connecting belt 14d of the second grinding roller assembly 15 is connected to the second synchronous wheel 12b, and the other end is connected to the connecting synchronous wheel 14c of the second grinding roller assembly 15, so that the second synchronous wheel 12b can drive the second grinding roller assembly 14 to rotate. One end of the connecting belt 14d of the third grinding roller assembly 16 is connected to the second tooth groove of the double-row synchronous wheel 13, and the other end is connected to the connecting synchronous wheel 14c of the third grinding roller assembly 16, so that the double-row synchronous wheel 13 can drive the third grinding roller assembly 16 to rotate. The first grinding roller assembly 14, the second grinding roller assembly 15 and the third grinding roller assembly 16 have the same structure, but are respectively connected to the first synchronous wheel 12a, the second synchronous wheel 12b and the double-row synchronous wheel 13.

[0033] Below the horizontal axis 3 are provided a placement plate 22 and an adsorption plate 23. The placement plate 22 is used to support the PVC plate for polishing. The adsorption plate 23 has hollow holes. When a thinner PVC plate is placed on it, it can be sucked through the air pipe to form a negative pressure adsorption to fix the plate for polishing.

[0034] The specific working principle is as follows: the PVC composite board or PVC board to be polished is placed on the workbench 1 or the placement plate 22 and the adsorption plate 23, depending on the specific situation on site. The operator then controls the cylinder 6 to drive the lower base 8 to press the three sets of polishing rollers to the appropriate distance. Then, the first motor 10 is activated to rotate the three sets of guide rollers to perform polishing. During this process, the motor 20 is rotated forward and reverse to reciprocate and polish the PVC board.
