[0012] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.
[0013] Figure 1 The three-dimensional structure of one embodiment is shown Figure 1 .
[0014] Figure 2 The three-dimensional structure of one embodiment is shown Figure 2 .
[0015] Figure 3 The three-dimensional structure of one embodiment is shown Figure 3 . DETAILED DESCRIPTION
[0016] like Figure 1~Figure 3 As shown, an edge processing mechanism includes a long bottom plate 1, and side plates 110 are provided on both sides of the long bottom plate 1. The two ends of the side plates 110 are respectively provided with waist-shaped holes 11. The lower side of the long bottom plate 1 is provided with a movable block 2, and the movable block 2 is respectively provided with a pair of limit pins 22, and the limit pins 22 are inserted into the waist-shaped holes 11. The movable block 2 is rotatably provided with a rotating shaft, and a grinding wheel 20 is provided at the upper end of the rotating shaft, and an arc-shaped annular groove 21 is provided on the grinding wheel 20. A driven bevel gear 23 is provided at the lower end of the rotating shaft, and the driven bevel gear 23 is meshed with a driving bevel gear 24. A spline sleeve 25 is provided on the driving bevel gear 24, and a spline shaft 26 is inserted in the spline sleeve 25. A vertical plate 27 is rotatably provided on the spline sleeve 25, and the vertical plate 27 is installed at one end of the movable block 2. Rotating seats 30 are respectively installed at both ends of the long bottom plate 1. Both ends of the spline shaft 26 are rotatably provided on the rotating seats 30. A motor 29 is installed on one of the rotating seats 30, and the output shaft of the motor 29 is connected to the spline shaft 26. A screw rod 28 is rotatably provided at the lower end of the rotating seat 30. The threads at both ends of the screw rod 28 have opposite rotation directions. The vertical plate 27 is provided on the screw rod 28, and a rotating cap 31 is provided at one end of the screw rod 28.
[0017] When performing the grinding operation on the side wall of the plate in this embodiment, the operator places the plate on the long bottom plate 1, and then the operator rotates the screw rod 28 by rotating the cap 31. The rotation of the screw rod 28 will drive the vertical plates 27 to approach each other, and the mutual approach of the vertical plates 27 will cause the grinding wheel 20 to act on both sides of the plate. Then the motor 29 is started, and the spline shaft 26 is rotated under the rotation of the motor 29. The rotation of the spline shaft 26 will drive the spline sleeve 25 and the driving bevel gear 24 to rotate. The rotation of the driving bevel gear 24 will drive the rotation of the driven bevel gear 23. The rotation of the driven bevel gear 23 will drive the grinding wheel 20 to rotate. Then the operator pushes the plate to make the plate pass through the rotating grinding wheel 20, and completes the grinding operation on both sides of the plate through the grinding wheel 20.

A lower plate 34 is provided on the push plate 33. A long hole 35 is opened on the lower plate 34, and a positioning screw is passed through the long hole 35, and an L-shaped clamping plate 36 is provided at the upper end of the positioning screw.
[0019] In this embodiment, the operator places the plate on the lower plate 34 and uses the L-shaped clamping plate 36 to limit one end of the plate, thereby preventing the plate from tilting and affecting the grinding operation.
[0020] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model.
