[0022] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0023] Example: like Figure 1 and Figure 2 As shown, a glass high-speed fine grinding straight line double-edging machine comprises: A bed mechanism 1, the bed mechanism 1 comprises a base 11, two groups of supporting seats 12 which are symmetrically arranged, one group being fixed on the base 11 and the other group being laterally slidably arranged on the base 11, and a driving assembly 13 for driving the supporting seats 12 to move; Conveying mechanism 2, two groups of conveying mechanism 2 are symmetrically arranged and correspondingly installed on the supporting seat 12, which includes an upper conveying belt assembly 21, a lower conveying belt assembly 22 arranged below the upper conveying belt assembly 21, and an adjusting assembly 23 driving the upper conveying belt assembly 21 to move up and down, and a glass conveying channel 20 is formed between the upper conveying belt assembly 21 and the lower conveying belt assembly 22; A guide mechanism 4, wherein the guide mechanism 4 is arranged at the front side of the conveying mechanism 2 and communicated with the glass conveying channel 20; Grinding mechanism 3, two groups of the grinding mechanism 3 are symmetrically arranged and correspondingly installed on the supporting seat 12, which include a plurality of groups of side grinding components 31 and a plurality of groups of chamfering components 32 arranged outside the conveying mechanism 2 and arranged front and back along the glass conveying direction; The chamfering assembly 32 includes a mounting seat 321, a slide unit 322 disposed on the mounting seat 321 and provided with two sets of slide plates 3221 that can move up and down, an electric spindle 323 symmetrically disposed up and down and correspondingly mounted on the slide plates 3221, a conical grinding wheel 324 correspondingly disposed at the power output end of the electric spindle 323, and a power assembly 325 for driving the two sets of slide plates 3221 to move simultaneously and the upper slide plate 3221 to move alone; During grinding, the conical surfaces of the upper and lower groups of conical grinding wheels 324 are in contact with the sharp corners of the glass edge at the same time; when the conical grinding wheels 324 are worn, the power assembly 325 drives the two groups of slide plates 3221 to move simultaneously to change the grinding position of the conical grinding wheels 324; when the thickness of the glass changes, the upper slide plate 3221 moves alone to adapt to the thickness of the glass.

[0024] It should be noted that the conical surface of the conical grinding wheel 324 is a grinding surface, and its angle is 45 degrees.

[0025] It is worth mentioning that the electric spindle 323 is a prior art, and its principle structure will not be explained in detail in the present invention.

[0026] It is particularly important to note that when the upper and lower groups of conical grinding wheels 324 are grinding at the same time, the upper and lower sides of the glass are evenly stressed, the grinding effect is better, and at the same time the equipment concentrates the workstations. Compared with traditional equipment, the equipment proposed in the present invention occupies a smaller area.

[0027] Furthermore, the driving assembly 13 includes two groups of ball screw pairs a131 arranged front and back along the glass conveying direction and arranged below the movable supporting seat 12, a reducer a132 correspondingly arranged at the end of the ball screw pair a131, a connecting shaft a133 for power connection between the two groups of the reducer a132, and a reduction motor a134 installed on the rear side of the reducer a132.

[0028] It should be noted that the movable supporting seat 12 is installed on the base 11 through a slide rail and a slider. Under the driving action of the reduction motor a134, the two groups of reducers a132 simultaneously drive the corresponding ball screw pairs a131 to move, so that the movable supporting seat 12 can be close to or away from the fixed supporting seat 12, so that the equipment can be used for glass of different widths.

[0029] Furthermore, the conveying mechanism 2 also includes a gear box 25 arranged on the rear side of the supporting seat 12 and powered by the upper conveyor belt assembly 21 and the lower conveyor belt assembly 22, a reduction motor b26 powered by the gear box 25, and a hexagonal shaft 27 powered by the gear boxes 25 on the left and right sides.

[0030] Furthermore, the upper conveyor belt assembly 21 and the lower conveyor belt assembly 22 each include two groups of synchronous wheels 200 arranged front and rear, a synchronous belt 201 wound around the outside of the two groups of synchronous wheels 200, a crossbeam 202 arranged between the two groups of synchronous wheels 200, and a guide strip 203 arranged on the upper and lower sides of the glass conveying channel 20 and used to guide the synchronous belt 201; the synchronous belt 201 in the lower conveyor belt assembly 22 is longer than the synchronous belt 201 in the upper conveyor belt assembly 21, and the rear sides of the two are aligned up and down.

[0031] It should be noted that, under the action of the guide strips 203, the upper and lower groups of the synchronous belts 201 will not derail, so that the transportation of the glass is more stable.

[0032] It should be further explained that the transmission ratio of the gear box 25 is 1:1, the speeds of the upper conveyor belt assembly 21 and the lower conveyor belt assembly 22 remain consistent, and under the action of the hexagonal shaft 27, a total of four conveyor belt assemblies maintain the same speed.

[0033] It is worth mentioning that the lower conveyor belt assembly 22 is longer than the upper conveyor belt assembly 21 and serves as a loading end, so as to facilitate guiding the glass into the glass conveying channel 20 .

[0034] Further, such as Figure 1 and Figure 2 As shown, the adjustment component 23 includes two sets of mounting frames 231 which are arranged on the supporting seat 12 in the front and rear and connected to the beam 202 below, a reduction box b232 which is correspondingly installed on the top of the mounting frame 231, a dovetail slide unit 233 which is correspondingly arranged above the mounting frame 231 and is powered by the reduction box b232, a connecting shaft b234 which is powered to connect the two sets of reduction boxes b232, and a hand wheel 235 which is powered by the reduction box b232 on the front side.

[0035] It should be noted that rotating the hand wheel 235 can cause the dovetail slide unit 233 to drive the upper beam 202 to move up and down, thereby realizing the movement of the upper conveyor belt assembly 21, and adjusting the height of the glass conveying channel 20, thereby satisfying the requirements of glass of different thicknesses entering the glass conveying channel 20.

[0036] Further, such as Figure 3 and Figure 4As shown, the guide mechanism 4 includes two groups of mounting platforms 41 symmetrically arranged and correspondingly mounted on the two groups of the supporting seats 12, two groups of fixing seats 42 arranged front and rear on one group of the mounting platforms 41, two groups of bottom blocks 43 arranged at the middle position of the two groups of the fixing seats 42, guide columns 44 correspondingly arranged vertically on the bottom blocks 43, a moving plate 45 slidably arranged on the bottom blocks 43, two groups of limiting grooves 46 opened on the moving plate 45 and correspondingly accommodating the guide columns 44, a plurality of groups of guide wheels a47 arranged on the moving plate 45 and arranged in an array along the glass feeding direction, a square nut 48 arranged on the moving plate 45 and correspondingly arranged with the fixing seats 42, and a square nut 48 connecting the square nut 48. A nut 48 and an adjusting screw 49 of the fixing seat 42, a guide seat 410 extending forward and backward and arranged on another group of the mounting platforms 41, a sliding plate 411 slidably arranged on both sides of the guide seat 410, a cylinder a412 installed between the two groups of the sliding plates 411, a guide wheel mounting plate 413 connected to the power output shaft of the cylinder a412, two groups of guide shafts 414 arranged on both sides of the cylinder a412 and connected to the guide wheel mounting plate 413, guide sleeves 415 correspondingly arranged on the two groups of the sliding plates 411 and used for the guide shafts 414 to pass through, and a plurality of groups of guide wheels b416 arranged in an array on the guide wheel mounting plate 413 along the glass feeding direction.

[0037] It should be noted that the cylinder a412 drives the guide wheel mounting plate 413 and the guide wheel b416 to move forward, and the guide wheel b416 pushes the glass and makes the other side contact with the guide wheel a47 to achieve alignment of the glass and ensure polishing accuracy.

[0038] It should be further explained that the position of the movable plate 45 can be adjusted by rotating the adjusting screw 49, thereby adjusting the position of the guide wheel a47 to meet different positioning requirements.

[0039] It is particularly important to explain that a top screw which can be set to abut against the guide seat 410 is also threadedly installed on the sliding plate 411, and the top screw is fixed to fix the position of the sliding plate 411 and the cylinder a412.

[0040] It is worth mentioning that the guide mechanism 4 is installed on both sides of the extended portion of the lower conveyor belt assembly 22 .

[0041] Further, such as Figure 5 and Figure 6As shown, the side grinding assembly 31 includes a mounting base plate 311, a slide plate a312 arranged on the mounting base plate 311 by sliding fit, a power head spindle 313 arranged on the slide plate a312, a transition base plate 314 arranged on the power head spindle 313, a motor mounting plate 315 installed above the transition base plate 314 by a screw, a motor 316 arranged on the motor mounting plate 315, a transmission unit 317 for connecting the motor 316 and the power head spindle 313 by power, a ball screw pair b318 arranged below the slide plate a312, a motor seat 319 arranged at the end of the ball screw pair b318, a servo motor a310 connected to the ball screw pair b318 by a coupling, and a grinding head 3110 arranged at the end of the power head spindle 313.

[0042] It should be noted that the grinding head 3110 is installed at the front end of the power head spindle 313 to make the rotation of the grinding head 3110 more stable, and the grinding head 3110 is installed in a side-fixed manner, which is convenient for disassembly, assembly and maintenance.

[0043] It is also necessary to explain that the feeding of the grinding head 3110 is achieved by the servo motor a310 driving the ball screw pair b318 to rotate, thereby making the feeding amount more accurate, and the compensation of the grinding head 3110 after wear can be automatically compensated to improve the grinding accuracy.

[0044] It is worth mentioning that the motor 316 is a three-phase asynchronous motor, and the transmission unit 317 is a synchronous pulley transmission unit.

[0045] Further, such as Figures 9 to 14 As shown, the slide unit 322 also includes a slide seat 3222 arranged on the mounting seat 321 and dovetailed with the slide plate 3221, a ball screw pair c3223 arranged in the slide seat 3222 and power-connected to the slide plate 3221, a gear a3224 correspondingly arranged at the end of the ball screw pair c3223, and a screw cylinder 3225 correspondingly arranged on the slide plate 3221 and having a power output end that can abut against the slide seat 3222.

[0046] It should be noted that after the slide plate 3221 is moved to a suitable position, the shaft of the screw cylinder 3225 is ejected and contacts the slide seat 3222, thereby limiting the slide plate 3221 and preventing the slide plate 3221 from moving due to its own gravity and the pressure generated during grinding, thereby further ensuring the grinding accuracy.

[0047] It should be noted that if Fig. 9 and Fig.10As shown, since the moving ranges of the upper slide plate 3221 and the lower slide plate 3221 are different, the installation positions of the ball screw pair c3223 and the slide plate 3221 are different.

[0048] Further, such as Figures 7 to 10 As shown, the power assembly 325 includes a rotating shaft 3251 vertically penetrated on the mounting seat 321 through a shaft sleeve, two groups of gears b3252 arranged on the rotating shaft 3251 and capable of meshing with the upper and lower groups of gears a3224 at the same time, a gear c3253 arranged above the upper gear b3252 and capable of meshing with the gear a3224, a cylinder mounting seat 3254 arranged on the top of the mounting seat 321, a base 3255 arranged on the top of the mounting seat 321 and located on one side of the cylinder mounting seat 3254, a worm gear 3256 coaxially arranged with the rotating shaft 3251, a pad 3257 arranged on the base 3255 and coaxially abutting against the bottom of the worm gear 3256, a pressing plate 3258 installed on the base 3255 and abutting against the top of the worm gear 3256, and a rotating plate 3258 mounted on the base 3255. A worm 3259 on the base 3255 and connected to the worm wheel 3256 in power, a cylinder b32510 mounted on the cylinder mounting seat 3254 and arranged opposite to the rotating shaft 3251, a connecting piece 32511 arranged at the power end of the cylinder b32510, a T-shaped rod a32512 arranged at the end of the connecting piece 32511, a guide block 32513 arranged on the connecting piece 32511, a guide groove 32514 arranged on the cylinder mounting seat 3254 and slidingly matched with the guide block 32513, a T-shaped rod b32515 arranged at the upper end of the rotating shaft 3251, a hoop 32516 connecting the T-shaped rod a32512 and the T-shaped rod b32515, and a servo motor b32517 mounted on the base 3255 and connected to the worm 3259 through a coupling.

[0049] It should be noted that if Fig. 9 As shown, the cylinder b32510 pulls the rotating shaft 3251 upward, so that the gear a3224 and the gear b3252 are meshed correspondingly, and the servo motor b32517 drives the worm 3259 to rotate, thereby driving the worm wheel 3256 and the rotating shaft 3251 to rotate, and under the transmission action of the gear a3224 and the gear b3252, the upper and lower groups of the ball screw pairs c3223 are driven to rotate, thereby driving the slide plate 3221 to move, and the distance between the two groups of the conical grinding wheels 324 can be adjusted to achieve compensation of the conical grinding wheels 324 after being used for a period of time.

[0050] What needs to be explained more is that Fig.10As shown, the cylinder b32510 drives the rotating shaft 3251 to move downward, and only the gear a3224 above is engaged with the gear c3253, and the servo motor b32517 drives the worm 3259 to rotate, thereby driving the worm wheel 3256 and the rotating shaft 3251 to rotate, and under the transmission action of the gear a3224 and the gear c3253, the ball screw pair c3223 above is driven to rotate, thereby driving the slide plate 3221 above to move, and the conical grinding wheel 324 above approaches or moves away from the conical grinding wheel 324 below. When the glass thickness is changed, the conical grinding wheel 324 below is used as a positioning basis, and the conical grinding wheel 324 above moves to adapt to the glass thickness.

[0051] It is worth mentioning that Fig.11 and Fig.12 As shown, the clamp 32516 is a two-half structure, and under the action of the guide block 32513 and the guide groove 32514, the piston shaft of the cylinder b32510 will not rotate with the rotating shaft 3251.

[0052] It is particularly important to note that the worm wheel 3256 and the worm 3259 have a self-locking capability, and under the action of the screw cylinder 3225, the position of the slide plate 3221 is more accurately positioned.

[0053] It should be further explained that the number of teeth of the gear a3224, the gear b3252 and the gear c3253 remain consistent.

[0054] Further, such as Fig.13 As shown, the thickness of the conical region of the conical grinding wheel 324 is α, and the thickness of the glass is β, then α=1 / 2β.

[0055] It should be noted that when the above conditions are met, it can be ensured that all areas of the conical grinding surface of the conical grinding wheel 324 can be used.

[0056] Working process: Grinding process: the cylinder b32510 pulls the rotating shaft 3251 upward, so that the gear a3224 and the gear b3252 are meshed correspondingly, and the servo motor b32517 drives the worm 3259 to rotate, thereby driving the worm wheel 3256 and the rotating shaft 3251 to rotate, and under the transmission action of the gear a3224 and the gear b3252, the upper and lower groups of the ball screw pairs c3223 are driven to rotate, thereby driving the slide plate 3221 to move, and the two groups of the conical grinding wheels 324 move to the appropriate position. At the same time, the servo motor a310 drives the ball screw pair b318 to rotate so that the grinding head 3110 moves to the appropriate position, and then the grinding wheel to be ground is moved to the grinding wheel 3110. The glass is placed on the front end protruding area of ​​the lower conveyor belt assembly 22, and the cylinder a412 drives the guide wheel mounting plate 413 and the guide wheel b416 to move forward. The guide wheel b416 pushes the glass and makes the other side contact with the guide wheel a47. Then the upper conveyor belt assembly 21 and the lower conveyor belt assembly 22 drive the glass into the glass conveying channel 20, and the grinding head 3110 and the conical grinding wheel 324 grind the edge of the glass. After the grinding head 3110 and the conical grinding wheel 324 are worn for a period of time, under the driving action of the servo motor b32517 and the servo motor a310, the grinding head 3110 and the conical grinding wheel 324 perform compensatory feeding.

[0057] Glass thickness conversion process: the cylinder b32510 drives the rotating shaft 3251 to move downward, and only the gear a3224 above is engaged with the gear c3253, and the servo motor b32517 drives the worm 3259 to rotate, thereby driving the worm wheel 3256 and the rotating shaft 3251 to rotate, and under the transmission action of the gear a3224 and the gear c3253, the ball screw pair c3223 above is driven to rotate, thereby driving the slide plate 3221 above to move, and the conical grinding wheel 324 above is close to or away from the conical grinding wheel 324 below to adapt to the glass thickness, and at the same time, the handwheel 235 is rotated so that the dovetail slide unit 233 drives the upper beam 202 to move up and down, so as to adjust the glass conveying channel 20 to meet the conveying requirements after the glass thickness changes.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
