Wherein, the grinding head is selected according to the limit of the national standard of the grinding wheel industry on rough grinding and fine grinding.

After the plate is fed, the plate sequentially passes through the bevel edge rough grinding head 211, the bevel edge refined grinding head 221, the side edge rough grinding head, the upper chamfering grinding head 241, the lower chamfering grinding head 242 and the side edge refined grinding head 251 to form a finished plate with bevel steps, chamfers and smooth side surface grinding. Wherein, hypotenuse rough grinding head 211 and hypotenuse fine grinding head 221 are used for the shaping of polishing of inclined plane step, and the more than two hypotenuse rough grinding head 211 and hypotenuse fine grinding head 221 are arranged in proper order, and their starting point of polishing reduces in order, through above-mentioned setting, polishes out the inclined plane step through less cutting volume once, and grinding stability is good, and heating control is outstanding.

In addition, through the both sides limit and the hypotenuse of once only polishing out panel such as glass, can improve the processing speed of one time at least than current unilateral edging machine, greatly improved production efficiency, increase the benefit of enterprise.
Because the application adopts a process mode of grinding two sides simultaneously, the plate is positioned between two rows of grinding heads which are relatively fixed in the grinding process, the angle and the position control during feeding must be accurate, otherwise, the plate which is fed at high speed can collide with the grinding heads, so that the side edges or the grinding heads of the plate are damaged, and even the plate is wholly broken. Therefore, the second embodiment of the present application additionally provides a guide frame 4 for correcting the feeding position and orientation of the sheet material at the feeding port.
Referring to fig. 3 and 4, in particular, the guide frame 4 includes a movable seat 41, a guide assembly 42, a sliding assembly 43, and a telescopic mechanism 44, wherein the sliding assembly 43 is connected to the movable seat 41 so that the movable seat 41 can directionally slide perpendicular to the feeding direction; the telescopic mechanism 44 is connected with the movable seat 41 and is used for adjusting the sliding displacement of the movable seat 41 under the restriction of the sliding component 43; the guiding assembly 42 includes guiding wheels 421, and the guiding wheels 421 are arranged on the movable seat 41 in rows along the feeding direction.

As a preferred embodiment, the sliding groove 431 and the sliding rail 432 are two groups, and are arranged at the bottom of the movable seat 41 in parallel; wherein, the chute 431 is connected with the movable seat 41, and the notch is downward; the slide rail 432 is fixedly disposed. The sliding assembly 43 further includes a sliding assembly cover 433 disposed around the sliding groove 431 and the sliding rail 432, and the sliding assembly cover 433 wraps the sliding groove 431 and the sliding rail 432, so as to prevent the chips generated during the grinding process from entering the sliding groove 431 and the sliding rail 432, and affect the service life of the sliding assembly 43. The guide assembly 42 further comprises a buffer steel plate 422, and the guide wheel 421 is connected with the movable seat 41 through the buffer steel plate 422. When the material to be ground (such as glass) passes through the guide frame 4, the guide wheels 421 in a row start to contact with the edges of the two sides of the glass one by one, so that the glass is overlapped with a preset feeding track, the edges of the glass to be ground are parallel to the feeding track, the subsequent contact with the grinding head is ensured to be uniform, and the grinding effect is uniform. During the adjustment of the glass travel path by the guide wheel 421, the buffer steel plate 422 is bent under pressure, and the adjustment pressure is provided by the buffer steel plate 422.

The telescopic mechanism 44 is hinged to the first swinging seat 45, and can swing up and down with the hinge point as an axis, so that the telescopic mechanism 44 can still smoothly drive the movable seat 41 to move when the movable seat 41 is adjusted up and down.
After ensuring that the feeding position and the self-placing angle of the plate before feeding can be accurately controlled, the next problem to be solved is to implement bevel edge grinding of the plate. Because the feeding amount of the bevel edge grinding is large, the pressure generated by the grinding head is also large, in addition, in order to meet the requirement of double-side quick grinding, the bevel edge rough grinding assembly 21 and the bevel edge fine grinding assembly 22 are composed of a plurality of grinding heads which are sequentially arranged and the grinding starting points of which are gradually reduced, and the bevel edge rough grinding assembly 21 and the bevel edge fine grinding assembly 22 need to integrally overturn when the bevel edges with different angles are formed by grinding, so that a turnover device is required to be capable of providing enough pressure to ensure the feeding precision of the grinding heads; the grinding heads have enough rigidity, so that the relative positions of the grinding heads in the compression process are not changed; the device has enough swinging precision, and can ensure that the inclination of the grinding bevel edge can be quickly adjusted according to the needs. To this end, the third embodiment of the present application also proposes a balance beam mechanism 3, and the bevel edge rough grinding assembly 21 and the bevel edge finish grinding assembly 22 are both provided on the balance beam mechanism 3.

The second swing seat 314 is provided with a bevel rough grinding assembly 21 and a bevel fine grinding assembly 22 for grinding. When the sheet material is required to form the bevel edge of a predetermined angle, the bevel edge rough grinding assembly 21 and the bevel edge fine grinding assembly 22 are required to form the bevel of the predetermined angle with the sheet material edge when the grinding head is contacted with the sheet material edge. At this time, the connecting arm 313 may be driven to swing around the fixed turntable 311 by the screw mechanism 323 to swing the second swing seat 314 by a predetermined angle, thereby forming a predetermined angle between the hypotenuse rough grinding assembly 21 and the hypotenuse fine grinding assembly 22 fixed to the second swing seat 314 and the plate material.
