Description

Technical Field

[0001] This utility model relates to the technical field of glass bending and tempering equipment, and in particular to a continuous sheet conveying structure for bending and tempering glass. Background Technology

[0002] Existing glass bending and tempering equipment uses a receiving table and a receiving table to transport bent tempered glass produced continuously by bending air grids.

[0003] After installation, the curved air grille, the receiving platform, and the unloading platform are fixed in position and cannot be moved. The curved air grille is equipped with multiple first conveying rollers, the receiving platform is equipped with multiple second conveying rollers, and the unloading platform is equipped with multiple third conveying rollers. The receiving platform also includes a mounting frame, a moving drive mechanism, and a base. The multiple second conveying rollers are mounted on the mounting frame, the mounting frame is mounted on the moving drive mechanism, and the moving drive mechanism is mounted above the base. The moving drive mechanism is used to drive the mounting frame to move back and forth along the top face of the base.

[0004] During operation, the first conveying roller located at the bending grid sequentially conveys the glass to be bent steel arranged at intervals to the bending grid. The bending grid maintains the set process curvature and continuously outputs the formed bent steel glass forward. Since there is a certain installation gap between the bending grid and the receiving table, in order to ensure that the bent steel glass can smoothly reach the conveying surface composed of multiple second conveying rollers, it is necessary to move the mounting frame backward along the top surface of the base through the moving drive mechanism to adjust the gap between the last second conveying roller and the bending grid, so that the last second conveying roller is close to the glass output end of the bending mechanism in the bending grid in the horizontal direction.

[0005] If there is a large height difference between the glass output end and the plane where the second conveying roller is located, one end of the mounting frame can be lifted by the lifting mechanism installed on the receiving table, so that the second conveying roller at the rear moves upward and closer to the glass output end of the bending mechanism.

[0006] When the multiple second conveyor rollers located on the receiving table move backward, the distance between the foremost second conveyor roller and the last third conveyor roller increases. The smaller the bending radius of the formed bent tempered glass, the easier it is for the bent tempered glass to fall into and get stuck in the gap between the receiving table and the unloading table, which may even cause damage to the bent tempered glass and affect the production efficiency of the glass bending and tempering equipment. Utility Model Content

[0016] The limit switch is connected to the lifting cylinder via a signal.

[0017] Furthermore, it also includes a double-groove pulley and two single-groove pulleys;

[0030] A continuous sheet conveying structure for bending tempered glass includes a bending air grid 1, a receiving platform 2, and a lowering platform 3 arranged sequentially along the conveying direction. The bending air grid 1 is equipped with multiple first conveying rollers 12, the receiving platform 2 is equipped with multiple second conveying rollers 22, and the lowering platform 3 is equipped with multiple third conveying rollers 31. The receiving platform 2 can move back and forth along the conveying direction and also includes a liftable transition roller 4.

[0031] The transition roller 4 is disposed between the receiving platform 2 and the unloading platform 3, and is located in the transition area between the foremost second conveying roller 22 and the last third conveying roller 31; the transition roller 4 can be adjusted vertically within the transition area; the transition roller 4 can rotate so that the glass that moves into the transition area is smoothly conveyed to the unloading platform 3 by the transition roller 4.

[0032] Figure 1 This is a schematic diagram of the installation structure of one embodiment of the continuous sheet feeding and conveying structure for bent tempered glass according to this utility model. Figure 2 This is a schematic diagram of the installation structure of one embodiment of the transition roller 4, the second conveying roller 22, and the third conveying roller 31 of this utility model. Figure 3 This is a schematic diagram of the installation structure of an embodiment of the unraised transition roller 4 and the third conveying roller 31 of this utility model.

[0033] Figure 1 The receiving platform 2 also includes a mounting frame 23, a moving drive mechanism 24, and a base 25. Multiple second conveying rollers 22 are mounted on the mounting frame 23. The mounting frame 23 is mounted on the moving drive mechanism 24. The moving drive mechanism 24 is mounted above the base 25. The moving drive mechanism 24 is used to drive the mounting frame 23 to move back and forth along the top surface of the base 25.

[0034] like Figure 1-3 As shown, after installation, the positions of the bending grid 1, the receiving platform 2, and the unloading platform 3 are fixed and immovable. During operation, the first conveying roller 12 sequentially conveys the glass to be bent steel arranged at intervals to the bending grid 1. The bending grid 1 maintains the set process curvature and continuously outputs the formed bent steel glass forward. Since there is a certain installation gap between the bending grid 1 and the receiving platform 2, in order to enable the bent steel glass to smoothly reach the conveying surface composed of multiple second conveying rollers 22, the moving drive mechanism 24 drives the mounting frame 23 to move backward along the top surface of the base 25 to adjust the gap between the last second conveying roller 22 and the bending grid 1, so that the last second conveying roller 22 is close to the glass output end 111 of the bending mechanism 11 in the bending grid 1 in the horizontal direction.

[0035] If there is a large height difference between the glass output end 111 and the horizontal plane of the second conveying roller 22, the rear end of the mounting frame 23 can be lifted by the lifting mechanism 21 installed on the receiving platform 2, so that the second conveying roller 22 at the rear can move upward and approach the glass output end 111 of the bending mechanism 11.

[0036] When the receiving platform 2 moves backward, the distance between the foremost second conveyor roller 22 and the last third conveyor roller 31 increases. The smaller the curvature radius of the formed curved tempered glass, the easier it is for it to get stuck between the foremost second conveyor roller 22 and the last third conveyor roller 31. At this time, the distance threshold can be set and output according to the curvature radius of the curved tempered glass required by the production process. When the distance between the foremost second conveyor roller 22 and the last third conveyor roller 31 is equal and greater than the set threshold, the transition roller 4 is raised to a position that is horizontally aligned with the second conveyor roller 22 and the third conveyor roller 31. This prevents the formed curved tempered glass from getting stuck between the foremost second conveyor roller 22 and the last third conveyor roller 31, and allows the curved tempered glass to be transported to the last third conveyor roller 31 through the foremost second conveyor roller 22 and the transition roller 4.

[0037] When the bending radius of the produced curved steel glass changes, and when the distance between the foremost second conveying roller 22 and the last third conveying roller 31 is less than the distance threshold, the transition roller 4 can be lowered below the second conveying roller 22 and the third conveying roller 31, so that the curved steel glass is directly conveyed from the foremost second conveying roller 22 to the last third conveying roller 31.

[0038] Furthermore, it also includes a support frame 8 and at least two lifting cylinders 7;

[0039] The two lifting cylinders 7 are mounted on the lower plate platform 3 at a distance from each other, and are located below the third conveying roller 31 at the rear end;

[0040] The left and right ends of the support frame 8 are respectively mounted on the output ends of the two lifting cylinders 7, and the transition roller 4 is mounted on top of the support frame 8.

[0041] like Figure 3 As shown, the support frame 8 and the transition roller 4 can be raised and lowered synchronously by the synchronous start and stop of the two lifting cylinders 7.

[0042] Furthermore, it also includes limit switch 5;

[0043] One end of the limit switch 5 is mounted on the receiving platform 2, and the other end of the limit switch 5 faces the lower platform 3. The limit switch 5 is used to detect the distance between the foremost second conveying roller 22 and the last third conveying roller 31.

[0044] The limit switch 5 is signal-connected to the lifting cylinder 7.

[0045] like Figure 2In the preferred embodiment shown, the limit switch 5 can be installed at the front end of the mounting frame 23, with the detection end of the limit switch 5 facing the lower platen 3. When the distance between the mounting frame 23 and the lower platen 3 increases and is equal to or greater than the distance threshold, the limit switch 5 sends a signal, the lifting cylinder 7 is activated, and the transition roller 4 is raised.

[0046] Conversely, when the distance between the mounting frame 23 and the lower plate stage 3 decreases and becomes less than the distance threshold, the limit switch 5 sends a signal, the lifting cylinder 7 closes, and the transition roller 4 descends.

[0047] Furthermore, it also includes a double-groove pulley 6 and two single-groove pulleys 9;

[0048] The two single-groove pulleys 9 are respectively fitted onto the outer circumferential surface of the third conveying roller 31 at the rear end and one end of the transition roller 4;

[0049] The two single-groove pulleys 9 are respectively connected to the double-groove pulley 6 via two belts.

[0050] like Figure 3 As shown, the drive motor 33 located on the lower platen 3 drives multiple third conveyor rollers 31 to rotate synchronously through the sprocket transmission device 32. Through the transmission connection structure of two single-groove pulleys 9 and double-groove pulleys 6 respectively, the power of the drive motor 33 on the lower platen 3 can be used to drive the transition rollers 4 to rotate synchronously.

[0051] Preferably, the outer peripheral surface of the transition roller 4 is wound with an aramid braided rope 41.

[0052] like Figure 3 As shown, aramid braided rope 41 is wound around the outer circumference of the transition roller 4 to prevent the output curved steel glass from making rigid contact with the transition roller 4, and to avoid cracks in the curved steel glass caused by excessive temperature difference between the curved steel glass and the metal outer circumference of the transition roller 4.

[0053] Preferably, the linear speeds of the transition roller 4, the second conveying roller 22, and the third conveying roller 31 are the same.

[0054] Setting the linear speeds of the transition roller 4, the second conveying roller 22, and the third conveying roller 31 to be the same can improve the conveying stability of curved steel glass.

[0055] In summary, such as Figure 1-3 The embodiment of the present invention shown in the figure has a continuous sheet conveying structure for bending tempered glass. By setting a liftable transition roller 4 in the transition area, the bending tempered glass can be prevented from getting stuck in the transition area.

[0056] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
