[0036] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0037] As Figures 1 to 4 shown, a glass edge grinding device is disclosed in a specific embodiment of the present invention, which includes a rolling support platform 100, a grinding device 200, and a limiting device 300; the rolling support platform 100 is used for rolling support of the glass plate, and the distance between the grinding part and the position where a person can stand can be adjusted by adjusting the deformation; the limiting device 300 is arranged on one side of the rolling support platform 100 and is used for rolling support of one side of the grinding edge of the glass plate; the grinding device 200 is installed on the vertical frame 400 and is located above the middle of the limiting device 300. The grinding disc 210 of the grinding device 200 passes through the middle of the two support components 310 of the limiting device 300; a grinding groove 211 is arranged on the side wall of the grinding disc 210. The grinding groove is in a closed loop shape around the axis of the grinding disc and is a V-shaped groove structure; the relative protruding range of the grinding disc 210 can be changed by adjusting the position of the support component 310 of the limiting device 300; the grinding device 200 can be vertically moved by adjustment so that the grinding disc 210 matches the supporting plane of the rolling support platform 100; and the limiting device 300 moves vertically with the grinding device 200.

[0038] In the above-mentioned glass edge grinding device, the grinding groove is in a closed loop shape around the axis of the grinding disc and is a V-shaped groove structure; when the edge of the glass plate enters the grinding groove, the edge of the glass plate contacts the groove wall of the grinding groove, so as to achieve the effect of synchronously grinding the upper and lower edges; or a single edge can be ground according to the adjustment of the central plane.

[0039] Based on the basic structure of this grinding device and grinding disc, with the cooperation of the rolling support platform and the limiting device, multi-dimensional automatic adjustment can be carried out according to the plate thickness and cutting depth requirements of the glass plate, which can improve the adjustment speed and accuracy, thereby improving the work efficiency and cutting quality.

[0040] Among them, the rolling support platform can adjust the distance between the grinding part and the position where a person can stand by adjusting the deformation, adapt to the grinding of glass plates of different sizes, and can adjust the size of the workbench according to requirements, providing a more suitable working position for the staff to operate in a comfortable posture, improving work efficiency and quality.

[0041] Furthermore, this equipment also includes a water supply pump and a water spray head for providing cooling water or polishing fluid to the polishing part; it also includes an infrared sensor for monitoring and adjusting the moving distance, such as detecting the vertical height of the grinding disc, the extension distance of the support component, etc., and an electrical control box, through which the thickness of the glass to be polished and the polishing depth can be input, and the position of the limit device and the polishing device can be adjusted by automatic adjustment, and the movement can be accurately adjusted to a suitable working position; it should be noted that the water supply pump and the water spray head are common equipment and instruments in the field of polishing equipment, the infrared sensor used for distance measurement is also a common detection sensor, and the electrical control box is also a common electrical control device, which can all be purchased and used on the market, and the installation and use methods are also very conventional, so the details will not be repeated.

[0042] Furthermore, the grinding device 200 includes a grinding disc 210, a first motor 220, and a first screw structure 230; the first screw structure 230 is rotatably mounted on the stand 400 through a bearing seat, a first bracket 240 is mounted on the first sleeve of the first screw structure 230, the first motor 220 is mounted on the first bracket 240, the grinding disc 210 is fixedly mounted on the output shaft of the first motor 220, and a first infrared sensor for detecting the distance from the top of the stand is mounted on the first bracket; the first bracket 240 extends downward on one side close to the rolling platform, and a first bracket 241 is fixedly provided at the bottom position, and both ends of the first bracket extend toward both ends of the rolling platform; a limit device 300 is mounted on the first bracket 241; with the above structure, the first motor drives the first screw structure shaft to move, thereby driving the first bracket to move, and then driving the first motor and the grinding disc to move to the desired position; wherein, the limit device is also raised and lowered as it is moved, maintaining its positional relationship with the grinding disc, and providing the required rolling support for the edge grinding part.

[0043] Furthermore, if Figure 2 , Figure 5 As shown, the limiting device 300 includes a second motor 320, a first transmission structure 330, and two support assemblies 310; the support assembly 310 includes a support groove 311 with an opening toward one side of the rolling platform, and a plurality of support rollers 312 evenly spaced along the length direction are rotatably installed in the support groove 311, and the side walls of the support rollers 312 protrude outside the groove opening of the support groove 311; a second infrared sensor for detecting the distance of the support groove is installed on the groove wall of the first bracket, and the second motor 320 is installed on the first bracket 241. The second motor 320 is connected to the support assembly 310 through the first transmission structure 330, and is used to drive the support assembly to move along the width direction of the first bracket to change the relative protrusion range of the grinding disc; by adjusting the position of the support assembly, the depth of the glass plate entering the grinding groove is limited to meet the corresponding grinding depth.

[0044] Furthermore, if Figure 5 , Figure 6As shown, the first transmission structure 330 includes a screw 334, a first pulley 331, a second pulley 332, and a first synchronous belt 333. At least two screws 334 are rotatably installed on the rear wall of each support groove 311. Threaded holes 242 are provided in the groove wall of the first support groove 241 corresponding to the screws, and the screws are in threaded connection with the threaded holes. A chute 335 extending along the length direction is provided on the side wall of the end of the screw 334 away from the support groove. A first pulley 331 is sleeved on the section of the screw 334 where the chute 335 is provided. A first slider 336 matching the chute 335 is provided on the inner wall of the first pulley 331. A limiting groove 340 is provided on the rear wall of the first support groove 241 corresponding to the multiple first pulleys 331. The bottom of the first pulley 331 is rotatably clamped at the limiting groove 340. The second motor is installed at one end of the first support groove. The second pulley 332 is installed on the output shaft of the second motor 320. The second pulley 332 is in transmission connection with the multiple first pulleys 331 through the first synchronous belt 333. The limiting groove includes a channel steel. A partition is fixedly provided at the bottom of the channel steel. A clamping channel adapted to the thickness of the second pulley is formed between the partition and the groove wall away from the first support groove. The other side of the channel steel is fixedly installed on the outer wall of the first support groove through bolts. The bottom of the second pulley is rotatably arranged at the clamping channel, which neither affects the rotation action nor allows the second pulley to move along with the screw, thus maintaining an effective transmission connection and simultaneously realizing the telescopic adjustment action of the screw, so that the support assembly can be moved to the required position.

[0045] Furthermore, a T-shaped groove with an open top and a sealed bottom is fixedly provided on the rear wall of the first support groove. The bottom end of the T-shaped groove is an arc-shaped structure. A circular plate is fixedly provided at the end of the screw away from the chute. The diameter of the circular plate is adapted to the groove width of the T-shaped groove, and the diameter of the screw is adapted to the groove opening width of the T-shaped groove. The circular plate and the screw are rotatably clamped in the T-shaped groove, which can not only effectively prevent detachment but also does not affect the rotation of the screw, thereby driving the support assembly to achieve the required adjustment and movement action.

[0046] Furthermore, a threaded pipe seat is also installed on the rear wall of the support groove for installing the second guide rod. A second guide hole is correspondingly provided on the rear wall of the first support groove. The second guide rod slides along the second guide hole, which can further limit the movement of the support assembly, thereby realizing a smooth movement adjustment.

[0047] It should be noted that the first transmission structure can also adopt a rack and pinion transmission structure. For example, a rack can be connected and installed on the rear wall of the support groove. The groove wall of the first bracket is provided with holes or slots for guiding corresponding to the rack. Then, a long drive shaft is erected on the first bracket, and a gear corresponding to the rack is installed on the drive shaft. The gear meshes with the rack. The output shaft of the second motor is connected to one end of the drive shaft through a coupling. When the second motor drives the drive shaft to rotate, the rack is driven to move, thereby adjusting the position of the support assembly and realizing the corresponding adjustment action. However, it should be noted that due to the low meshing accuracy of the gear and the rack, a better way is to select the above-mentioned structure with a screw pair, which can improve the adjustment accuracy and provide a better grinding effect.

[0048] Furthermore, as Figure 2 、 Figure 7 and Figure 8 shown, a cleaning structure 500 is provided below the first motor 220; the cleaning structure 500 includes a second bracket 510, a push plate 520, an electromagnet 530, a magnet block 540, and a first spring 550; the second bracket 510 includes a tray, and a first vertical plate 511 and a second vertical plate 512 are fixedly provided on the bottom surface of the tray. The first vertical plate is located at one end of the tray, and the first vertical plate 511 is fixed to the first bracket 240 by bolts; at least two first guide rods 521 are fixedly provided on the wall surface of the push plate 520 away from the first vertical plate. Corresponding first guide holes 513 are provided on the second vertical plate 512. The first guide rods 521 movably penetrate through the first guide holes 513, and a retaining ring for preventing detachment is installed at the end position; the first spring 550 is sleeved on the first guide rods 521 to provide an elastic force for pushing the push plate towards the first vertical plate; a magnet block 540 is fixedly embedded on the wall surface of the push plate 520 close to the first vertical plate, and an electromagnet 530 is correspondingly installed on the second bracket 510; a cleaning brush 560 is installed at the bottom of the wall surface of the push plate 520 away from the first vertical plate, corresponding to the grinding disc; when the electromagnet is powered on, the repulsive force between the electromagnet and the magnet block overcomes the elastic force of the first spring, so that the bristles of the cleaning brush abut against the outer wall of the grinding disc; when the electromagnet is not powered on, the first spring pushes the push plate to reset, so that the bristles of the cleaning brush are separated from the grinding disc; the power-on of the electromagnet 530 is controlled by a foot switch 600; this structural design provides an additional cleaning structure for the grinding disc. In addition to flushing with water, it also provides the action of brushing with a cleaning brush, effectively improving the cleaning effect on the grinding disc; it can be cleaned before and after grinding to reduce the influence of impurity residues on the grinding quality, or when it feels that the grinding is not smooth during the grinding process, it can also be started for brushing and cleaning, all in order to improve the grinding quality; and, a foot switch is used for control, which is convenient for control so as to be started during work.

[0049] Further, one side of the supporting plate is fixedly provided with an extension plate, and at least two bayonets are arranged on the extension plate. At each bayonet, a water spray head is clamped and installed. The water spray head is communicated with an external water supply pump through a water delivery hose. One water spray head corresponds to the grinding part where the grinding disc contacts the glass plate, and the other water spray head corresponds to the cleaning part of the cleaning brush. Among them, a three-way solenoid valve is installed at the output port of the water supply pump, and the two output ports are respectively connected to the water spray head through a water delivery hose. The corresponding channel can be opened by controlling the power connection to achieve the effect of spraying water from a single water spray head. Especially during the conventional grinding process, only the channel of the water spray head for spraying water on the grinding part can be opened. When it is necessary to brush and clean the grinding disc, the other channel is opened to achieve targeted water supply and reduce waste.

[0050] Further, a plurality of through holes penetrating the bottom surface are provided at the bottom of the first bracket groove for draining the liquid splashed to the first bracket groove to prevent water accumulation problems.

[0051] Further, as Figure 1 , Figure 9 , Figure 10 shown, the rolling support platform 100 includes two oppositely arranged support frames 110, and the two support frames are respectively arranged corresponding to the two ends of the first bracket groove. A plurality of mounting plates 120 are erected between the tops of the two support frames 110. A plurality of bull's-eye bearings 130 are evenly spaced along the length direction and installed on the top surface of the mounting plate 120. The balls of the plurality of bull's-eye bearings form a rolling support plane. The spacing between the mounting plates can be adjusted. The overall structure is simple. The rolling support effect is provided by multiple mounting plates and the bull's-eye bearings installed on the mounting plates. By adjusting the spacing between the mounting plates, the entire support range can be adjusted and can be matched and adjusted according to actual needs. Among them, the bull's-eye bearing is a plastic bull's-eye bearing structure, which can provide the required rolling support effect and also prevent the problem of scratching and abrasion of the glass plate. It should be noted that the bull's-eye bearing can be purchased and used on the market, and will not be elaborated here.

[0052] Further, as Figure 9 shown, a slide rail 140 is installed on the top surface of the support frame 110. The slide rail extends in a direction perpendicular to the first bracket groove. Sliding seats 141 are correspondingly installed at both ends of the bottom surface of the mounting plate 120. The mounting plate 120 is installed on the slide rail 140 through the sliding seats 141 and slides along the slide rail to provide sliding support and reduce the operating load of the subsequent driving components.

[0053] A second lead screw 150 is mounted on the top surface of the support frame 110 through a bearing seat, one end of the second lead screw extends to the bottom of the first bracket, and a third pulley 161 is mounted on the ends of the two second lead screws 150; a second bracket 410 is fixedly provided on the side of the stand 400 close to the rolling platform, and a transmission rod 162 is mounted at the second bracket 410 through a bearing seat, one end of the transmission rod 162 is connected to the output shaft of the third motor 170 through a coupling, and the third motor is installed inside the stand; a fourth pulley 163 is installed on the transmission rod 162, and the fourth pulley 163 is connected to the two third pulleys 161 through a second synchronous belt 164.

[0054] A second sleeve 151 is mounted on the second lead screw 150, and the second sleeve is fixedly connected to the frame plate farthest from the stand by bolts; the two frame plates closest to the stand are fixed to the support frame by bolts; a plurality of second springs 190 are sleeved on the second lead screw 150;

[0055] Except for the fixed spacing between the two frame plates, a second spring is provided between any other two adjacent frame plates, and the second spring is used to maintain the supporting force for the unfolding of the frame plates; this structural design cooperates with the second lead screw and the second sleeve, and when the second sleeve moves toward the vertical frame, it can drive the frame plate at the farthest position to move, and by compressing the second spring, some of the frame plates are moved closer toward the vertical frame, thereby achieving a narrowing effect; when the second sleeve moves away from the vertical frame, the force applied to the second spring is reduced, and the frame plates are pushed open and unfolded under the elastic force of the second spring; the overall cooperation can adjust the arrangement range of the frame plates according to usage requirements, thereby providing a suitable rolling support range; wherein, a third infrared sensor needs to be installed at the farthest end of the frame plate to detect its distance to the end of the support frame, thereby monitoring the unfolded or closed position of the frame plates and the overall support range.

[0056] Furthermore, support blocks are fixedly provided at the bottom of both ends of the frame plate, and a through hole penetrating the two side walls is provided in the middle of the support block, the aperture of the through hole is larger than the diameter of the second lead screw, and the second lead screw passes through the support block through the through hole; sink grooves are provided at the two ends of the through hole, and the outer diameter of the sink groove is adapted to the outer ring diameter of the second spring. By providing the sink grooves, the two ends of the second spring are provided with limiting and supporting effects, so as to prevent the second spring from being too loose and irregularly deformed, thereby maintaining an effective elastic support effect;

[0057] In addition, the top surface of the support frame is provided with a clamping groove for fixing the support blocks of the two frame plates close to one side of the vertical frame. The support blocks can be fixed in the clamping groove by bolts, so that the two frame plates always maintain a fixed position and will not be spread out or closed together, providing a stable support for the bottom of the grinding part. Even if the frame bars in other parts change slightly, it will not affect the grinding action.

[0058] Furthermore, as Figure 1 shown, a hanging bracket 180 is installed on the bottom surface of the frame plate 120 away from the first bracket 241 by bolts.
