Description

Technical Field

[0001] This utility model relates to the technical field of sign bending equipment, specifically a sign bending and positioning device. Background Technology

[0002] Signage is now ubiquitous in our lives, becoming an indispensable part of our daily routines. It serves as a directional sign, enabling us to reach our destinations more quickly and conveniently. It also acts as an informational sign, providing quick guidance when we arrive at a tourist attraction or scenic area. Currently, at some right-angle turns, symmetrically bent signs are required to be installed so that pedestrians on both sides of the turn can quickly understand their destination.

[0003] For example, the announcement number CN217191789U is titled "A Bending and Forming Device for Sign Production". The device includes a base, a bending groove, a vertical groove, and a horizontal groove communicating with the vertical groove. A stop block is slidably connected to the vertical groove.

[0004] The aforementioned devices cannot effectively secure the signs during use, and misalignment of the bending position is likely to occur during bending. If the sign breaks, it may cause injury to personnel, which is detrimental to ensuring processing safety. Furthermore, the bending position cannot be quickly and conveniently adjusted, increasing the bending time and reducing the working efficiency of the bending device. Therefore, we propose a sign bending positioning device to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sign bending and positioning device, comprising a workbench with an opening inside, a gantry frame installed at both ends of the top of the workbench, a first threaded rod installed at both ends of the upper left side of the workbench via the gantry frame, a first drive motor installed on the left side of the first threaded rod, a first nut seat threadedly connected to the outer wall of the first threaded rod, a second threaded rod installed at both ends of the upper right side of the workbench via the gantry frame, a second drive motor installed on the right side of the second threaded rod, a second nut seat threadedly connected to the outer wall of the second threaded rod, a lower limit roller installed between the two first nut seats and the two second nut seats, an upper limit roller installed above the lower limit roller, lifting components installed at both ends of the upper limit roller, a movable seat sleeved on the upper part of the gantry frame, a connecting plate installed between the two movable seats, multiple sets of hydraulic cylinders installed at the bottom of the connecting plate, and bending blocks installed at the bottom of the hydraulic cylinders.

[0007] Preferably, an mounting plate is installed at the middle position of both ends of the top of the workbench, and the right side of the first threaded rod and the left side of the second threaded rod are respectively connected to the two sides of the mounting plate.

[0008] Preferably, the lifting assembly includes two fixed frames, which are respectively located at the top between the two first nut seats and the top between the two second nut seats. The fixed frames are inverted U-shaped. A third threaded rod is installed at both ends of the top of the fixed frame. A third drive motor is installed at the top of the third threaded rod. A third nut seat is threaded to the outer wall of the third threaded rod. The upper limit roller is installed between the two third nut seats at both ends.

[0009] Preferably, the two ends of the lower limit roller on the left are rotatably connected to the first nut seat via bearings, the two ends of the lower limit roller on the right are rotatably connected to the second nut seat via bearings, and the two ends of the upper limit roller are rotatably connected to the third nut seat via bearings.

[0010] Preferably, the movable seat has a through groove inside, a gear is installed inside the through groove, the two ends of the gear are connected to the inner wall of the through groove through a rotating shaft, one end of the rotating shaft passes through the movable seat and is equipped with a fourth drive motor, and a toothed plate is installed on the top of the gantry frame, and the gear meshes with the toothed plate.

[0011] Preferably, the bottom of the gantry frame is provided with a T-shaped slide groove, and an I-shaped slider is slidably connected inside the T-shaped slide groove. The bottom of the I-shaped slider is fixedly connected to the inner bottom of the through groove.

[0012] Preferably, the workbench is equipped with support legs around its bottom, and the bottom of the support legs is equipped with shock-absorbing pads.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model uses a first drive motor and a second drive motor to make the first threaded rod and the second threaded rod rotate synchronously, driving the first nut seat and the second nut seat to move along the length direction of the worktable, adjusting the two lower limit rollers to a suitable position to accommodate different sizes of signs, and placing the sign to be bent on the two lower limit rollers. At the same time, the third drive motor starts, making the third threaded rod rotate, and controlling the lifting and lowering of the upper limit roller through the third nut seat. The lower limit roller and the upper limit roller work together to position the sign to accommodate signs of different thicknesses. The bearing can greatly reduce the friction between the lower limit roller and the upper limit roller and the sign, avoiding the sign jamming or wear caused by direct contact, ensuring that the sign moves smoothly during the bending process. This solves the problem that the existing sign bending device cannot effectively fix the sign during use, and is prone to misalignment of the bending position during bending. Once the sign breaks, it is easy to accidentally injure personnel, which is not conducive to ensuring processing safety.

[0015] (2) The fourth drive motor drives the rotating shaft to rotate, and the rotation of the rotating shaft can drive the gear to rotate synchronously. The gear can rotate and move on the gear plate through the meshing connection between the gear and the tooth plate, thereby driving the moving seat to move on the gantry, thus realizing the position adjustment of the bending block. This solves the problem that the existing sign bending device cannot quickly and conveniently adjust the bending position during use, which increases the bending time and reduces the working efficiency of the bending device.

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides an embodiment of a sign bending and positioning device, including a workbench 1 with an opening inside. A gantry frame 2 is installed at both ends of the top of the workbench 1. First threaded rods 3 are installed at both ends of the upper left side of the workbench 1 via the gantry frame 2. A first drive motor 4 is installed on the left side of the first threaded rod 3, and a first nut seat 5 is threadedly connected to the outer wall of the first threaded rod 3. Second threaded rods 6 are installed at both ends of the upper right side of the workbench 1 via the gantry frame 2. A second drive motor 7 is installed on the right side of the second threaded rod 6, and a second nut seat 8 is threadedly connected to the outer wall of the second threaded rod 6. (See also...) Figure 2 Mounting plates 9 are installed at the middle positions of both ends of the top of the workbench 1. The right side of the first threaded rod 3 and the left side of the second threaded rod 6 are connected to the two sides of the mounting plates 9, respectively. A lower limit roller 10 is installed between the two first nut seats 5 and the two second nut seats 8. An upper limit roller 16 is installed on the upper part of the lower limit roller 10. Lifting components are installed at both ends of the upper limit roller 16. Please refer to [link / reference]. Figure 3 and Figure 4The lifting assembly includes two fixed frames 12, which are located at the top between two first nut seats 5 and the top between two second nut seats 8, respectively. The fixed frames 12 are inverted U-shaped. The two ends of the top of the fixed frame 12 are equipped with third threaded rods 13. The top of the third threaded rods 13 is equipped with a third drive motor 14. The outer wall of the third threaded rods 13 is threaded with a third nut seat 15. An upper limit roller 16 is installed between the two third nut seats 15 at both ends. When bending of the sign is required, the first drive motor 4 and the second drive motor 7 are first started, causing the first threaded rod 3 and the second threaded rod 6 to rotate synchronously. This drives the first nut seat 5 and the second nut seat 8 to move along the length of the worktable 1, adjusting the two lower limit rollers 10 to suitable positions to accommodate signs of different sizes. The sign to be bent is then placed on the two lower limit rollers 10. Simultaneously, the third drive motor 14 is started, causing the third threaded rod 13 to rotate. The third nut seat 15 controls the raising and lowering of the upper limit roller 16. The combined action of the lower limit rollers 10 and the upper limit roller 16 positions the sign to accommodate signs of different thicknesses. Please refer to [link / reference]. Figure 4 The two ends of the lower limit roller 10 on the left are rotatably connected to the first nut seat 5 via bearings 11, and the two ends of the lower limit roller 10 on the right are rotatably connected to the second nut seat 8 via bearings 11. The two ends of the upper limit roller 16 are rotatably connected to the third nut seat 15 via bearings 11. When bending the sign, the sign will move. The bearings 11 can drive the lower limit roller 10 and the upper limit roller 16 to rotate. At the same time, the bearings 11 can significantly reduce the friction between the lower limit roller 10 and the upper limit roller 16 and the sign, avoiding jamming or wear of the sign due to direct contact, ensuring smooth movement of the sign during bending. A movable seat 17 is sleeved on the upper part of the gantry 2. A connecting plate 25 is installed between the two movable seats 17. Multiple sets of hydraulic cylinders 26 are installed at the bottom of the connecting plate 25, and bending blocks 27 are installed at the bottom of the hydraulic cylinders 26. Please refer to... Figure 3 and Figure 4 The movable seat 17 has a through groove 18 inside, and a gear 21 is installed inside the through groove 18. The two ends of the gear 21 are connected to the inner wall of the through groove 18 through a rotating shaft 22. One end of the rotating shaft 22 passes through the movable seat 17 and is equipped with a fourth drive motor 23. A toothed plate 24 is installed on the top of the gantry frame 2, and the gear 21 is meshed with the toothed plate 24. When the fourth drive motor 23 is started, it drives the rotating shaft 22 to rotate. The rotation of the rotating shaft 22 drives the gear 21 to rotate synchronously. The meshing connection between the gear 21 and the toothed plate 24 allows the gear 21 to rotate and move on the toothed plate 24, thereby driving the movable seat 17 to move on the gantry frame 2. This achieves the position adjustment of the bending block 27. The hydraulic cylinder 26 can drive the bending block 27 to move downward, thereby bending the signboard through the bending block 27.

[0023] Please see Figure 4 The bottom of the gantry 2 is provided with a T-shaped slide groove 19, and an I-shaped slider 20 is slidably connected inside the T-shaped slide groove 19. The bottom of the I-shaped slider 20 is fixedly connected to the inner bottom of the through groove 18. The movement of the movable seat 17 can drive the I-shaped slider 20 to move along the T-shaped slide groove 19. The cooperation between the T-shaped slide groove 19 and the I-shaped slider 20 ensures the smoothness and stability of the sliding process of the movable seat 17, thereby effectively improving the accuracy and reliability of the bending block 27 position adjustment.

[0024] Please see Figure 1 Support legs 28 are installed around the bottom of the workbench 1, and shock-absorbing pads 29 are installed at the bottom of the support legs 28. The support legs 28 provide support for the workbench 1, and the shock-absorbing pads 29 provide cushioning for the support legs 28, thereby improving the stability of the device.
