[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0039] Reference Figure 1-7 A glass processing turning table includes a base 1 and a support frame 2. A reducer 3 is fixedly installed in the middle of the top surface of the base 1, and a rotating shaft 4 is horizontally connected to the output end of the reducer 3.

[0040] A flipping arm 5 is sleeved and fixed at both ends of the outer side of the rotating shaft 4. The end of the flipping arm 5 away from the rotating shaft 4 is rotatably installed on the inner side of the U-shaped hinge seat 6 via the rotating shaft.

[0041] A rotating shaft 7 is horizontally fixed to one end of the bottom surface of the support frame 2 away from the U-shaped hinge seat 6. Support seats 8 are vertically fixed to both sides of the top surface of the base 1. A rotating bearing seat 9 is fixedly installed at the top of the support seat 8. The two rotating bearing seats 9 are respectively rotatably sleeved on the outer ends of the rotating shaft 7.

[0042] The end of the U-shaped hinge seat 6 away from the tilting arm 5 forms a sliding fit with the bottom surface of the support frame 2.

[0043] By adopting the above technical solution, through the coordinated cooperation of base 1, bearing frame 2, reducer 3, rotating shaft 4, tilting arm 5, U-shaped hinge seat 6, tilting shaft 7, support seat 8 and tilting bearing seat 9, the reducer 3 drives the rotating shaft 4 to rotate the tilting arm 5, the sliding cooperation between the U-shaped hinge seat 6 and the bearing frame 2 provides guidance for tilting, and the tilting shaft 7 achieves stable support through the tilting bearing seat 9, ultimately realizing the smooth and reliable tilting of the bearing frame 2 around the tilting shaft 7, meeting the core requirements of tilting operation in glass processing, with a compact transmission structure and efficient torque transmission.

[0044] Two channel steel plates 10 with downward openings and parallel arrangement are fixedly connected to the bottom surface of the support frame 2 at intervals. Linear rails 11 are fixedly connected to the inner side of the channel steel plates 10 along their length direction. The linear rails 11 are dovetail-shaped guide rails.

[0045] Each of the two U-shaped hinge seats 6 has a slider 12 fixedly connected to the outer wall of the end away from the flip arm 5. The two sliders 12 form a sliding fit with the two linear rails 11 respectively.

[0046] By adopting the above technical solution, the slider 12 on the U-shaped hinge seat 6 and the dovetail guide rail 11 form a matching sliding fit, which not only ensures the smooth sliding of the U-shaped hinge seat 6 relative to the support frame 2, but also restricts the sliding direction through the structural characteristics of the dovetail guide rail 11 to avoid deviation, thereby ensuring the motion accuracy of the flipping arm 5 when driving the support frame 2 to flip, reducing friction loss, and improving the stability of the flipping action.

[0047] A support frame 13 is vertically fixed to the middle of both sides of the top surface of the base 1, and a rotary bearing seat 14 is fixedly installed at the top of the support frame 13.

[0048] The two ends of the rotating shaft 4 pass through the two rotating bearing seats 14 on both sides and form a rotating connection with the rotating bearing seats 14.

[0049] By adopting the above technical solution, the support frame 13 on the base 1 and the rotary bearing seat 14 at the top end form a support structure for both ends of the rotary shaft 4. The rotary shaft 4 passes through the rotary bearing seat 14 and forms a rotatable connection, which effectively disperses the force on the rotary shaft 4, avoids bending or shaking during rotation, ensures the coaxiality and stability of the rotary shaft 4 transmission, and provides a uniform and reliable driving force for the tilting arm 5.

[0050] A large bushing is fixed to one end of the tilting arm 5 near the rotating shaft 4. The large bushing is fixed to the end of the rotating shaft 4 by a key connection.

[0051] A small bushing is fixed to one end of the tilting arm 5 away from the rotating shaft 4. A rotating shaft passes through the middle of the small bushing, and both ends of the rotating shaft are fixed to the inner wall of the U-shaped hinge seat 6.

[0052] Using the above technical solution, the tilting arm 5 is fixed by the key connection between the large bushing and the rotating shaft 4, ensuring that the torque of the rotating shaft 4 can be fully transmitted to the tilting arm 5. The connection is firm and easy to disassemble. The cooperation between the small bushing and the rotating shaft enables the tilting arm 5 and the U-shaped hinge seat 6 to form a flexible rotational connection, reducing mechanical interference during the tilting process, realizing the organic combination of power transmission and steering adjustment of the tilting arm 5, and improving the reliability of the overall transmission system.

[0053] A positioning block 15 is fixedly connected to one end of the inner side of each of the two channel steel plates 10. The positioning block 15 extends downward to the outer side of the channel steel plate 10. The two ends of the flipping shaft 7 are respectively fixedly inserted into the positioning blocks 15 on both sides.

[0054] Using the above technical solution, the positioning block 15 is fixed to the inside of the channel steel plate 10 and extends downward to provide a precise installation reference for the flipping shaft 7. The two ends of the flipping shaft 7 are fixed in the positioning block 15, so that the flipping shaft 7 and the support frame 2 form a stable connection, ensuring that the rotation center of the support frame 2 remains fixed when it flips, avoiding the flipping offset caused by the loosening of the flipping shaft 7, and improving the accuracy and safety of the flipping operation.

[0055] Multiple movable rollers 16 are installed at intervals and parallel along the length of the top surface of the support frame 2, and multiple non-marking rollers 17 are sleeved at intervals on the outer side of the movable rollers 16.

[0056] A sprocket cover 18 is fixedly installed on the support frame 2 along its length. The side of the sprocket cover 18 is provided with a clearance groove that is compatible with the movable roller 16. The first transmission sprocket 19 is fixedly sleeved on the outside of the movable roller 16 at the position inside the sprocket cover 18.

[0057] The first drive motor 20 is fixedly installed on the bottom surface of the support frame 2 below the sprocket cover 18. The output end of the first drive motor 20 meshes with each first transmission sprocket 19 through the transmission chain belt.

[0058] Using the above technical solutions, the movable roller 16 on the support frame 2, together with the outer non-marking roller 17, can avoid scratching the glass surface during glass conveying, thus achieving non-marking protection; the clearance slot on the side of the sprocket cover 18 provides space for the movable roller 16 to pass through; the first drive motor 20 drives all the first transmission sprockets 19 synchronously through the transmission chain belt, so that multiple movable rollers 16 operate synchronously, ensuring the stability and consistency of glass conveying process and improving conveying efficiency.

[0059] Multiple positioning rods 21 are fixedly connected at intervals along the width direction on the top surface of the support frame 2. At least two positioning bearing seats 22 are sleeved on the outer side of the movable roller 16. The bottom end of the outer wall of the positioning bearing seat 22 is detachably fixed to the positioning rod 21 by a screw.

[0060] With the above technical solution, the positioning bearing seat 22 is sleeved on the outside of the movable roller 16, which can provide reliable support for the movable roller 16, prevent radial displacement during operation, and ensure the stability of glass conveying; and the positioning bearing seat 22 is detachably connected to the positioning rod 21 by a screw, which facilitates subsequent maintenance.

[0061] A conveyor beam pipe 23 is fixedly connected to one side of the support frame 2. Multiple movable shafts 24 are installed in parallel and spaced apart by deep groove ball bearings on the inner side of the conveyor beam pipe 23.

[0062] The top end of the movable shaft 24 extends to the top surface of the conveyor beam tube 23 and is fixedly connected to a vertically arranged conveyor wheel 25. The bottom end of the movable shaft 24 is fixedly fitted with a second transmission sprocket 26.

[0063] A second drive motor 27 is fixedly installed on the side of the conveyor beam pipe 23. The second drive motor 27 drives each second transmission sprocket 26 to rotate synchronously through the transmission chain belt.

[0064] Using the above technical solution, the movable shaft 24 inside the conveying beam tube 23 can rotate flexibly through a deep groove ball bearing, and the top conveying wheel 25 is set vertically to guide and convey the glass side; the second drive motor 27 drives all the second transmission sprockets 26 synchronously through the transmission chain belt, so that multiple conveying wheels 25 operate synchronously, and cooperate with the movable roller 16 on the top surface of the support frame 2 to achieve stable and coordinated glass conveying and ensure the directional consistency of the glass during the glass conveying process.

[0065] On the other side of the support frame 2 away from the conveying beam pipe 23, multiple angle brackets 28 are fixedly connected at intervals. The top of the angle bracket 28 is fixedly connected to a longitudinal rod 29. The end of the longitudinal rod 29 away from the angle bracket 28 is fixedly connected to a support plate 30. The bottom side of the support plate 30 is fixedly connected to the outer side of the conveying beam pipe 23. Multiple parallel and spaced crossbars 31 are fixedly connected to the top of the multiple longitudinal rods 29.

[0066] Using the above technical solutions, the angle bracket 28, the longitudinal bar 29 and the support plate 30 form a stable frame structure. The support plate 30 and the conveying beam pipe 23 are fixedly connected to further enhance the rigidity of the overall structure and prevent structural deformation during conveying and flipping. The longitudinal bar 29 and the top crossbar 31 form a guardrail structure, which can prevent the glass from shifting or falling from the side during conveying or flipping, and at the same time improve the overall structural stability of the bearing frame 2.

[0067] A column is fixedly connected to both sides of the top surface of the base 1 and to the end away from the support 8, and a foot cup 32 is installed on the top surface of the column;

[0068] Each of the two channel steel plates 10 has a pad 33 fixedly installed at the end away from the positioning block 15, and the pad 33 corresponds to the foot cup 32 vertically.

[0069] With the above technical solution, the pad 33 on the channel steel plate 10 corresponds vertically to the foot cup 32. When the bearing frame 2 is in a horizontal state, the pad 33 and the foot cup 32 contact to form an auxiliary support, which disperses the force on the bearing frame 2, avoids structural subsidence caused by long-term use, and ensures the stability and service life of the equipment.

[0070] Working principle:

[0071] When the equipment is working, the reducer 3 drives the rotating shaft 4 to rotate the tilting arm 5. The U-shaped hinge seat 6 moves with the tilting arm 5 and slides along the dovetail guide rail 11 on the bottom surface of the support frame 2. With the fulcrum effect of the tilting shaft 7, the support frame 2 can be tilted smoothly. When conveying glass, the first drive motor 20 drives the movable roller 16 and the non-marking roller 17 to rotate through the transmission chain belt. The conveying direction is along the length of the crossbar 31. The longitudinal bar 29 and the crossbar 31 form a protective structure to prevent the glass from shifting or falling from the side when conveying or tilting. The glass is conveyed out from the outlets at both ends of the equipment along this direction. At the same time, the second drive motor 27 drives the conveying wheel 25 to assist in the guidance. The whole system meets the tilting and conveying requirements in glass processing.

[0072] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
