Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to a glass edge grinding machine. Background Art

[0002] Conventional rectangular glass needs to be ground during the production process. The existing method is to leave a wide enough gap between two conveying rollers for the edge grinding module to enter. When the glass passes through the gap, the edge grinding module can grind the glass edge. However, the various grinding wheels set on the existing edge grinding module are driven by a combination of a motor and a transmission belt. The space occupied by this structure is relatively large. In order to allow the edge grinding module to smoothly enter the gap, the distance of the gap must be made very wide. In this way, the distance between the two conveying rollers is very wide, and the small glass cannot pass smoothly, resulting in the grinding equipment being unable to process the small glass.

[0029] like Figure 2As shown, the conveying module 2 includes a plurality of conveying rollers 21, wherein an edge grinding gap L is formed between two conveying rollers 21, and the edge grinding module 3 is slidably connected with the crossbeam guide rail 1, so that the edge grinding module 3 slides in the edge grinding gap L; specifically, the crossbeam guide rail 1 is provided with a rack, and the edge grinding module 3 is provided with a gear, and the edge grinding module 3 can move along the rack by rotating the gear, so that the edge grinding module 3 moves along the crossbeam guide rail 1;

[0030] The edge grinding module 3 includes an edge grinding frame 31, an edge grinding wheel group and a servo motor 32. Each wheel in the edge grinding wheel group corresponds to a servo motor 32. Each wheel in the edge grinding wheel group is rotatably connected to the edge grinding frame 31. The output shaft of the servo motor 32 is fixedly connected to the shaft of the corresponding wheel in the edge grinding wheel group.

[0031] In the glass edge grinding machine, since each wheel in the edge grinding wheel group is driven by a servo motor 32, compared with the traditional motor plus transmission belt structure, it can greatly save space. In this way, the edge grinding gap L can be reduced as much as possible, thereby meeting the needs of small glass grinding processing.

[0032] It is worth noting that if Figure 3 As shown, the edging wheel assembly includes a chamfering grinding wheel assembly, a resin wheel 35, a film removal wheel 36 and a polishing wheel assembly, and the chamfering grinding wheel assembly, the resin wheel 35, the film removal wheel 36 and the polishing wheel assembly are arranged in sequence along the direction opposite to the movement direction when the edging module 3 enters the edging gap L, that is, Figure 1 and 3 The right-to-left direction in .

[0033] The glass is transported by the conveying roller 21 of the conveying module 2 and first moves toward the direction close to the edge grinding gap L. When the glass approaches the edge grinding gap L, the edge grinding module 3 will move along the length direction of the crossbeam guide rail 1, and the movement direction is perpendicular to the conveying direction of the conveying roller 21, so that the edge grinding wheel group enters the edge grinding gap L, and then the glass edge contacts the chamfering grinding wheel assembly, the resin wheel 35, the film removal wheel 36 and the polishing wheel assembly in sequence, wherein the chamfering grinding wheel assembly is used to grind the chamfer of the glass edge, the resin wheel 35 is used to eliminate the traces of chamfering and grinding the glass edge, the film removal wheel 36 is used to remove the film on the glass edge, and the polishing wheel assembly is used to polish the glass edge. After polishing, the edge grinding wheel group leaves the edge grinding gap L, and the glass can continue to be transported forward through the conveying roller 21 and pass through the edge grinding gap L to enter the next process.

[0034] Preferably, the chamfering grinding wheel assembly includes an upper chamfering grinding wheel 33 and a lower chamfering grinding wheel 34, a plurality of upper chamfering grinding wheels 33 are coaxially arranged and fixedly connected to the output shaft of the same servo motor 32, and a plurality of lower chamfering grinding wheels 34 are coaxially arranged and fixedly connected to the output shaft of the same servo motor 32; the rotating shaft of the upper chamfering grinding wheel 33 is parallel to the conveying roller shaft 21, and the rotating shaft of the lower chamfering grinding wheel 34 is parallel to the conveying roller shaft 21;

[0035] An upper chamfering gap is formed between two adjacent upper chamfering grinding wheels 33 , and a lower chamfering gap is formed between two adjacent lower chamfering grinding wheels 34 . The lower chamfering grinding wheels 34 are embedded in the upper chamfering gap so that the upper chamfering grinding wheels 33 are embedded in the lower chamfering gap.

[0036] Specifically, each upper chamfering gap only accommodates one lower chamfering grinding wheel 34, and each lower chamfering gap only accommodates one upper chamfering grinding wheel 33, so that the upper chamfering grinding wheel 33 and the lower chamfering grinding wheel 34 form a structure in which they are arranged in an interlaced manner. Through such an interlaced structure, the upper corner of the glass edge can be brought into contact with the upper chamfering grinding wheel 33 to achieve chamfering and grinding of the upper corner of the glass edge, and the lower corner of the glass edge can be brought into contact with the lower chamfering grinding wheel 34 to achieve chamfering and grinding of the lower corner of the glass edge. Since a plurality of upper chamfering grinding wheels 33 are provided, the outer circumferential walls of the upper chamfering grinding wheels 33 with increasingly smaller roughness can be sequentially arranged in the direction opposite to the direction of movement when the edge grinding module 3 enters the edge grinding gap L, thereby achieving a gradual transition from coarse grinding to fine grinding. Similarly, since a plurality of lower chamfer grinding wheels 34 are provided, the circumferential outer walls of the upper chamfer grinding wheels 33 with increasingly smaller roughness can be sequentially arranged in the direction opposite to the movement direction of the edge grinding module 3 when entering the edge grinding gap L, thereby achieving a gradual transition from coarse grinding to fine grinding.

Figure 3 As shown, the longitudinal direction of the rotating shaft of the resin wheel 35 is the front-to-back direction. The circumferential surface of the film removal wheel 36 contacts the glass edge to eliminate the traces of chamfering and grinding the glass edge.

[0039] Specifically, the rotating shaft of the film removal wheel 36 is perpendicular to the conveying roller shaft 21 so that the circumferential surface of the film removal wheel 36 faces the glass on the conveying roller shaft 21. Figure 3 As shown, the length direction of the rotating shaft of the resin wheel 35 is the front-to-back direction.

After the glass edge enters the polishing gap 39, the upper chamfer of the glass edge will contact the upper polishing wheel 37 to be polished, and the lower chamfer of the glass edge will contact the lower polishing wheel 38 to be polished.

[0042] like Figure 7 As shown, in this embodiment, the rotating shaft of the upper polishing wheel 37 and the rotating shaft of the lower polishing wheel 38 are connected to the edge grinding frame 31 through corresponding bearings 5.

[0045] The lifting cylinder 43 is arranged on the positioning frame 41 and the telescopic shaft of the lifting cylinder 43 is vertically facing downward, and the pressure wheel 42 is fixedly connected to the telescopic shaft of the lifting cylinder 43 through the pressure wheel bracket 44;

[0046] The swing assembly 46 includes a base 461 and a telescopic cylinder 462. The base 461 is rotatably connected to the positioning frame 41. The supporting wheel 45 is arranged on the base 461.

[0047] When the glass enters the conveying roller 21, the lifting cylinder 43 drives the pressing wheel 42 to descend and press down to the upper surface of the glass, and then the telescopic cylinder 462 drives the base 461 to swing, and the swing direction is as follows: Figure 5 As shown by the dotted arrow, the supporting wheel 45 is driven to move and abut against the side wall of the glass, and then the base 461 is further swung, so that the glass is pressed against the abutting wheel 22 located on the other side of the conveying roller 21 through the supporting wheel 45, thereby achieving the purpose of glass positioning, so that in the next grinding step, each wheel can be aligned with the glass edge in turn.
