The grinding assembly 43 correspondingly grinds the workpieces 21 with three sizes as follows: when the size of the workpiece 21 is proper, the friction surface 435 of the polishing assembly 43 is attached to the top wall of the lower end of the workpiece 21, the pressing piece 433 is attached to the upper end wall of the workpiece 21, and the arc-shaped block 432 polishes the side wall of the upper short side of the workpiece 21 through the polishing blade 44; when the thickness of the workpiece 21 is larger, the friction surface 435 of the grinding assembly 43 is abutted against the top wall of the lower end of the workpiece 21, the pressing piece block 433 is attached to the upper end wall of the workpiece 21, the arc-shaped block 432 grinds the side wall of the upper short side of the workpiece 21 through the grinding edge 44, and the friction surface 435 synchronously grinds the top wall of the lower end of the workpiece 21; when the thickness of the workpiece 21 is smaller, a gap is reserved between the grinding plate 434 of the grinding assembly 43 and the upper end wall of the workpiece 21, the pressing piece block 433 is not in contact with the upper end wall of the workpiece 21, and the arc-shaped block 432 grinds the upper short side wall of the workpiece 21 through the grinding edge 44.

In order to collect and clean the waste materials left by grinding the workpiece 21, the pressing piece block 433 is arc-shaped, the grinding plate 434 is fixed at the end part of the pressing piece block 433, the end part of the grinding plate 434 is inclined, the upper end surface of the grinding plate 434 and the upper end surface of the pressing piece block 433 are upwards bent to form a containing bin 45, and the waste materials of the workpiece 21 cut by the grinding knife edge 44 can fall into the containing bin 45. After all the workpieces 21 in the storage part 2 are machined, the bolts fixed on the fixing blocks 431 are taken down, and the waste materials in the accommodating bin 45 can be cleaned, so that the grinding assembly 43 can continue to machine the workpieces 21. Furthermore, it should be noted that the distance between the two oppositely disposed trimming edge portions 4 closest to the magazine portion 2 is greater than the length of the side wall of the short side of the workpiece 21, and this is provided for the purpose that since the scrap cut by the grinding blade 44 will fall into the correspondingly located accommodating pocket 45, these two trimming edge portions 4 should only provide the function of pressing the workpiece 21, but not grinding the workpiece 21.

In order to facilitate the packing of the finished workpieces 21, the upper end of the fixing support 1 is further fixed with a packing support 11, the upper end of the packing support 11 is horizontally fixed with a packing table 12, the packing table 12 is suitable for supporting the grinding assemblies 43 and the workpieces 21, the two grinding assemblies 43 are arranged on the packing table 12 in a mirror image mode, and the grinding assemblies 43 are fixed on the packing table 12. The two grinding assemblies 43 are oppositely arranged, and the distance between the two grinding assemblies 43 is larger than the length of the workpiece 21. A packing bag 13 is provided on the two grinding units 43, and the work 21 can be conveyed to the packing table 12 after being ground and can be inserted into the packing bag 13.

In order to facilitate the grinding assembly 43 to place the packaging bag 13, two hanging lugs 14 are respectively arranged on two sides of the packaging bag 13, and one hanging lug 14 is correspondingly hung on a pressing piece 433 which protrudes out of the grinding knife edge 44. The pressing piece blocks 433 on the two sides are flexible, after the workpiece 21 is inserted into the corresponding packaging table 12, the pressing piece blocks 433 are bent inwards due to impact force of the workpiece 21, at the moment, the hanging lugs 14 on the two sides of the packaging bag 13 slide down from the two sides of the pressing piece blocks 433 under the action of gravity and fall onto the collecting plate, an operator can collect the packaging bag 13 on which the workpiece is placed from the collecting plate, and the new packaging bag 13 is placed on the corresponding pressing piece blocks 433, so that the next work cycle is realized.

In light of the foregoing description of the preferred embodiment of the present invention, it is to be understood that various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
