Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to an upper beam guide rail structure. Background Technology

[0002] Glass is a brittle material, easily broken and scratched. To ensure the precision of glass processing, glass edging machines employ a feeding lifting assembly. Chinese utility model patent CN206169806U discloses an upper beam lifting assembly for a glass edging machine. Two columns are each equipped with a dovetail base plate, and dovetail slide plates are slidably connected to the base plates. An upper clamping beam connects the two dovetail slide plates on the two columns. Lead screws are connected to the dovetail slide plates via nuts, and the two lead screws on the two columns are linked together via a connecting shaft.

[0039] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0042] See Figures 1-7This utility model discloses an upper beam guide rail structure, including: an upper beam guide rail assembly 10, which is used to press against the conveyor belt 20 and extends along the length direction of the conveyor belt 20; a lifting mechanism 30, which is connected and fixed to the upper beam guide rail assembly 10 and is used to drive the upper beam guide rail assembly 10 to move up and down; and a tensioning mechanism 40, which is used to tension the conveyor belt 20.

[0043] This utility model sets up a lifting mechanism 30 to drive the upper beam guide rail assembly 10 to move up and down, thereby changing the setting height of the upper beam guide rail assembly 10. It also sets up a tensioning mechanism 40 to tension the conveyor belt 20, so that the upper beam guide rail assembly 10 can always press against the conveyor belt 20 in various application scenarios, thereby improving the accuracy of glass processing.

[0044] In this embodiment of the utility model, the upper beam guide rail assembly 10 includes a mounting base 101, an elastic element 102, and a guide rail 103. The elastic element 102 is disposed between the mounting base 101 and the guide rail 103, and the elastic element 102 drives the guide rail 103 to press against the conveyor belt 20.

[0045] In this embodiment of the utility model, the guide rail 103 is an integral guide rail; the elastic element 102 is a spring, elastic silicone or elastic rubber.

[0046] Specifically, the number and spacing of the elastic elements 102 are determined according to the actual situation and are not limited.

[0047] Since the guide rail 103 is an integral guide rail, the flatness of the guide rail 103 is relatively high, so that the guide rail 103 fits the conveyor belt 20 better, thereby making the conveyor belt 20 fit the glass better.

[0048] Furthermore, since an elastic element 102 is provided between the mounting base 101 and the guide rail 103, the elastic element 102 can prevent the guide rail 103 from impacting the conveyor belt 20 when it presses against the conveyor belt 20. The elastic element 102 can drive the guide rail 103 to press against the conveyor belt 20 more gently. During the up and down movement of the upper beam guide rail assembly 10, the guide rail 103 can be prevented from impacting the glass, thereby improving the yield rate.

[0049] In this embodiment of the present invention, the lifting mechanism 30 includes a lifting drive unit 301, a slide table 302, and a linear slide rail assembly. The upper beam guide rail assembly 10 is connected and fixed to the slide table 302. The lifting drive unit 301 drives the slide table 302 to move along the linear slide rail assembly, thereby driving the upper beam guide rail assembly 10 to move up and down. The linear slide rail assembly is provided with a dovetail groove for sliding cooperation with the slide table 302, and the slide table 302 is provided with a dovetail protrusion for cooperation with the dovetail groove; or, the linear slide rail assembly is provided with a dovetail protrusion for sliding cooperation with the slide table 302, and the slide table 302 is provided with a dovetail groove for cooperation with the dovetail protrusion.

[0050] Specifically, the mounting base 101 of the upper beam guide rail assembly 10 is connected and fixed to the slide table 302. The mounting base 101 can be directly connected and fixed to the slide table 302, or the mounting base 101 can be connected and fixed to the slide table 302 through components such as connecting plates. The above connection and fixing can be achieved by bonding, welding, screws or clips, depending on the actual situation, and is not limited.

[0051] Specifically, by utilizing the cooperation between the dovetail protrusion and the dovetail groove, the contact area between the linear guide rail assembly and the slide table 302 can be increased, thereby improving the stability of the slide table 302 sliding along the linear guide rail assembly.

[0052] In this embodiment of the present invention, the lifting mechanism 30 further includes a lifting screw 303, which is connected to the output end of the lifting drive unit 301. The slide table 302 is sleeved on the outside of the lifting screw 303 and is threadedly connected to the lifting screw 303. The lifting drive unit 301 is a motor, which drives the lifting screw 303 to rotate by rotating. The lifting screw 303 drives the slide table 302 to move up and down along the linear slide rail assembly by rotating.

[0053] In this embodiment of the utility model, the linear slide rail assembly includes a fixed slide rail 304, an adjustable slide rail 305, and an adjusting screw 306. The adjustable slide rail 305 is provided with a dovetail groove or a dovetail protrusion. The adjusting screw 306 is disposed between the fixed slide rail 304 and the adjustable slide rail 305. The gap between the fixed slide rail 304 and the adjustable slide rail 305 can be adjusted by rotating the adjusting screw 306.

[0054] Because there is a relative sliding process between the slide table 302 and the linear slide rail assembly, wear will occur between the slide table 302 and the linear slide rail assembly after long-term use. In order to avoid the phenomenon of unstable operation of the slide table 302 due to wear, the gap between the fixed slide rail 304 and the adjusting slide rail 305 is adjusted by rotating the adjusting screw 306, so that the adjusting guide rail 103 always fits against the slide table 302, thereby ensuring the stable operation of the slide table 302.

[0055] In this embodiment of the utility model, the upper beam guide rail assembly 10 extends along the first direction, and the lifting mechanism 30 moves up and down along the second direction, with the first direction and the second direction being perpendicular to each other.

[0056] Preferably, both ends of the upper beam guide rail assembly 10 are provided with lifting mechanisms 30, so that the upper beam guide rail assembly 10 can move up and down smoothly; when two lifting mechanisms 30 are provided, the two lifting mechanisms 30 can share a lifting drive unit 301 through a coupling, thereby simplifying the structure.

[0057] In this embodiment of the utility model, the tensioning mechanism 40 includes a fixed base 401, a tensioning cylinder 402, a rocker arm 403, and a tensioning wheel 404. The cylinder body of the tensioning cylinder 402 is rotatably connected to the fixed base 401. The telescopic rod of the tensioning cylinder 402, one end of the rocker arm 403, and the tensioning wheel 404 are rotatably connected. The other end of the rocker arm 403 is rotatably connected to the fixed base 401. The tensioning wheel 404 abuts against the inner side of the conveyor belt 20. The telescopic end of the tensioning cylinder 402 extends to drive the tensioning wheel 404 to tension the conveyor belt 20.

[0058] Specifically, within the lifting stroke range of the upper beam guide rail assembly 10, the tensioning mechanism 40 adjusts the tensioning wheel 404 to keep the conveyor belt 20 always in a taut state. When the upper beam guide rail assembly 10 rises, the telescopic rod of the tensioning cylinder 402 moves in the extending direction, at which time the tensioning wheel 404 tensions the conveyor belt 20. When the upper beam guide rail assembly 10 falls, the telescopic rod of the tensioning cylinder 402 moves in the retracting direction, at which time the tensioning wheel 404 tensions the conveyor belt 20. The extension distance of the telescopic rod of the tensioning cylinder 402 is adapted to the lifting stroke range of the upper beam guide rail assembly 10 so that the tensioning wheel 404 can always keep the conveyor belt 20 taut.

[0059] In this embodiment of the utility model, the conveyor belt 20 is used to be sleeved on the active conveyor wheel and the driven conveyor wheel to form a conveying mechanism. The active conveyor wheel is driven to rotate by the conveying drive mechanism 50. The conveying drive mechanism 50 includes a conveying drive unit 501, a reduction assembly, and a reduction gearbox 502. The reduction assembly is disposed in the inner cavity of the reduction gearbox 502. The conveying drive unit 501 is a motor. The reduction assembly includes a first reduction gear 503, a second reduction gear 504, a first drive shaft 505, and a second drive shaft 505. The first reduction gear 503 and the second reduction gear 504 mesh with each other. The first reduction gear 503 is sleeved on the first drive shaft 505 and is connected to the first drive shaft 505 in a driving connection. The second reduction gear 504 is sleeved on the second drive shaft 505 and is connected to the second drive shaft 505 in a driving connection. The input end of the first drive shaft 505 is connected to the output end of the conveying drive unit 501 in a driving connection. The output end of the second drive shaft 505 is connected to the active conveyor wheel in a driving connection.

[0060] In this embodiment of the present invention, the conveying drive mechanism 50 further includes a bearing assembly, which includes a first bearing 507, a second bearing 508, a third bearing 509, and a fourth bearing 510. A first drive shaft 505 passes through a reduction gearbox 502, which has a first connecting hole and a second connecting hole for the first drive shaft 505 to pass through. The first drive shaft 505 is rotatably connected to the first connecting hole via the first bearing 507 and to the second connecting hole via the second bearing 508. A second drive shaft 505 passes through a reduction gearbox 502, which has a third connecting hole and a fourth connecting hole for the second drive shaft 505 to pass through. The second drive shaft 505 is rotatably connected to the third connecting hole via the third bearing 509 and to the fourth connecting hole via the fourth bearing 510.

[0061] Specifically, by setting the first bearing 507 and the second bearing 508, the force on the first drive shaft 505 is more balanced, and by setting the third bearing 509 and the fourth bearing 510, the force on the second drive shaft 505 is more balanced, thereby improving the stability of the first drive shaft 505 and the second drive shaft 505 during rotation, thus improving the conveying stability of the conveying mechanism, which is particularly suitable for glass processing.
