Description

Technical Field

[0001] This utility model relates to the field of signboard bending technology, specifically a bending device for signboards. Background Technology

[0002] Signage is a visual marker used to convey specific information. It is commonly seen in daily life and typically includes text, graphics, or symbols. In modern society, signage is widely used in commercial activities, building signage, and public place guidance, serving to promote, instruct, and warn.

[0003] For curved signs, the manufacturing process requires bending the flat sign into shape using a bending machine. This involves feeding the sign into the machine from one end to the other, with the bending cutter repeatedly pressing down on the sign to fold it into an arc. This process is tedious, and controlling the curvature of the sign is difficult. Therefore, we propose a bending device for signs. Utility Model Content

[0024] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1 to 8 This utility model provides a technical solution: a bending device for signs, including a lower drive roller 8. One end of the lower drive roller 8 is rotatably mounted on the top of a support platform 18. Specifically, at least two bearing seats are installed on the top of the support platform 18, and one end of the lower drive roller 8 is rotatably positioned within the bearing seats, thus providing stable support for the lower drive roller 8. The lower drive roller 8 is driven to rotate by a driving device, i.e., a driving device connected to the lower drive roller 8 is provided below the support platform 18, such as... Figure 6 As shown, the driving device includes a drive motor 26 located below the support platform 18. A drive wheel 25 is provided on the shaft of the drive motor 26 and at the end of the lower drive roller 8. The drive wheels 25 are connected by a drive belt. Here, the drive wheel 25 is a pulley, a synchronous pulley or a sprocket, and the drive belt is a belt, a synchronous belt or a drive chain. When the drive motor 26 rotates, it can drive the lower drive roller 8 to rotate.

[0026] like Figure 3 and Figure 4 As shown, in actual use, support legs 17 are provided at the four corners of the bottom of the support platform 18. The support legs 17 are installed on the base 9, and the drive motor 26 is also installed on the base 9.

[0027] Next, an upper drive roller 5 is arranged parallel above the lower drive roller 8, and a mounting seat 10 is also arranged parallel above the support platform 18. One end of the upper drive roller 5 is rotatably connected to the lower part of the mounting seat 10, and the installation method is the same as that of the lower drive roller 8. Specifically, at least two bearing seats are installed under the support platform 18, allowing one end of the upper drive roller 5 to be rotatably installed in the bearing seats, thus providing stable support for the upper drive roller 5. At least two first guide seats 11 are provided on one side of the mounting seat 10, and a first guide support shaft 13 is movably installed in each first guide seat 11. The bottom of the first guide support shaft 13 is vertically connected to the support platform 18, so that the first guide seat 11 can drive the mounting seat 10 to move stably up and down along the first guide support shaft 13.

[0028] Each first guide support shaft 13 is equipped with a clamping mechanism at its top, which continuously applies pressure to the first guide seat 11. This clamping structure can press the first guide seat 11 downwards, ensuring that the upper drive roller 5 always has a downward tendency to move. Figure 3 and Figure 4As shown, the clamping mechanism includes clamping springs 12 sleeved on the top of each first guide support shaft 13. A clamping plate 27 is provided above the clamping spring 12. The clamping plate 27 is detachably connected to the top of the first guide support shaft 13. The two ends of the clamping spring 12 are in elastic contact with the clamping plate 27 and the first guide seat 11, respectively. During installation, the clamping plate 27 is ring-shaped. The clamping plate 27 is sleeved on the top of the first guide support shaft 13. A nut is threaded on the top of the first guide support shaft 13 to fix the clamping plate 27. The pressure on the clamping plate 27 can be adjusted by adjusting the nut, thereby adjusting the elastic force of the clamping spring 12.

[0029] Furthermore, in this application, the lower drive roller 8 can drive the upper drive roller 5 to rotate together when it rotates, as detailed below. Figure 5 , Figure 6 and Figure 7 As shown, a splined shaft 21 is provided on the side of the upper drive roller 5 near the mounting base 10, and a splined sleeve 22 is provided on the side of the lower drive roller 8 near the mounting base 10. The splined sleeve 22 is coaxial with the splined shaft 21, and the bottom of the splined shaft 21 is movably placed inside the splined sleeve 22, so the splined shaft 21 can freely extend and retract inside the splined sleeve 22.

[0030] The top of the spline shaft 21 needs to be fixed, so the top of the spline shaft 21 is rotatably mounted in the first support 19. One end of the first support 19 is connected to the mounting base 10, so that the spline shaft 21 can be stably fixed on one side of the mounting base 10. Similar to the spline shaft 21, the spline sleeve 22 also needs to be fixed during use. That is, the bottom of the spline sleeve 22 is rotatably mounted in the second support 24. The bottom of the second support 24 is set on the base 9, so the spline sleeve 22 can be firmly fixed on the base 9.

[0031] like Figure 6 and Figure 7 As shown, a first bevel gear 20 is provided at the end of both the spline shaft 21 and the upper drive roller 5, and the two first bevel gears 20 mesh with each other. A second bevel gear 23 is provided at the end of both the spline sleeve 22 and the lower drive roller 8, and the two second bevel gears 23 mesh with each other. Therefore, when the drive motor 26 drives the lower drive roller 8 to rotate, the lower drive roller 8 can drive the spline sleeve 22 to rotate through the meshing of the second bevel gears 23. The spline sleeve 22 can then drive the spline shaft 21 to rotate. Thus, the spline shaft 21 can drive the upper drive roller 5 to rotate through the meshing of the first bevel gears 20, ultimately causing the lower drive roller 8 to rotate and thus driving the upper drive roller 5 to rotate as well.

[0032] It should also be noted that, for example Figure 7As shown, a limiting seat 28 is provided at the bottom of the first guide support shaft 13, coaxially sleeved on the first guide support shaft 13 or disposed around the first guide support shaft 13. When the first guide seat 11 falls to the top of the limiting seat 28, there is a clearance fit between the upper drive roller 5 and the lower drive roller 8 (the fit tolerance can be zero). This clearance tolerance is smaller than the thickness of the sign. When the sign is placed between the upper drive roller 5 and the lower drive roller 8, the upper drive roller 5 and the lower drive roller 8 can clamp the sign while also conveying it forward. Because the sign has a certain thickness, when the upper drive roller 5 and the lower drive roller 8 clamp the sign, the upper drive roller 5 will move upward due to the support of the sign. At this time, the power of the upper drive roller 5 can still be continuously provided. Figure 6 As shown, when the upper drive roller 5 moves upward, the mounting base 10 will drive the spline shaft 21 to move upward, causing the spline shaft 21 to be pulled upward from the spline sleeve 22. However, the power connection between the spline shaft 21 and the spline sleeve 22 will not be interrupted, so different thicknesses of identification plates can be placed between the upper drive roller 5 and the lower drive roller 8.

[0033] Furthermore, this application also provides an adjusting roller 6 parallel to one side of the lower transmission roller 8. The adjusting roller 6 is rotatably mounted on the support arm 7, that is, both ends of the adjusting roller 6 are rotatably mounted on the bearing seats, the bearing seats are mounted on the support arm 7, and one end of the support arm 7 is connected to the screw lifting mechanism located at the top of the support platform 18. The screw lifting mechanism can drive the support arm 7 to move up and down, thereby allowing the support arm 7 to drive the adjusting roller 6 to move up and down.

[0034] Based on the above embodiments, the specific process of bending the sign is as follows: Figure 8 As shown, after the upper drive roller 5 and the lower drive roller 8 clamp the sign and move it forward, the sign comes into contact with the adjusting roller 6. Since the adjusting roller 6 can be adjusted up and down, it is positioned above the lower drive roller 8. Therefore, the adjusting roller 6 can lift the end of the sign upward. After the sign comes out between the upper drive roller 5 and the lower drive roller 8, it is continuously bent by the adjusting roller 6. Moreover, the higher the adjusting roller 6 is, the greater the curvature of the sign bending. The lower the adjusting roller 6 is, the smaller the curvature of the sign bending. This makes it convenient to adjust the bending curvature of the sign.

[0035] Furthermore, such as Figure 3As shown, the screw lifting mechanism includes at least two second guide support shafts 15 vertically mounted on the support platform 18. The tops of the second guide support shafts 15 are connected to the connecting seat 14 to fix them in place. A second guide sleeve 16, corresponding to the second guide support shaft 15, is provided at one end of the support arm 7 near the support platform 18. The second guide sleeve 16 is movably mounted on the second guide support shaft 15. To allow the support arm 7 to move up and down, a screw 3 threadedly connected to the support arm 7 is provided parallel to the second guide support shafts 15. The bottom of the screw 3 is rotatably connected to the support platform 18, and the top of the screw 3 is rotatably connected to the connecting seat 14. A crank handle 2 is provided on the top of the screw 3, allowing the operator to manually rotate the screw 3 to adjust the height of the adjusting roller 6.

[0036] Furthermore, the base 9 has a cabinet 1 on top, and the cabinet 1 has an opening 4 on the side corresponding to the support arm 7, the upper transmission roller 5 and the lower transmission roller 8, and the top of the lead screw 3 is located above the top of the cabinet 1.

[0037] Based on the above embodiments, further optimization is possible: the crank handle 2 at the top of the lead screw 3 can be removed, and a motor can be installed at the bottom or top of the lead screw 3, so that the lead screw 3 can also be driven to rotate by the motor.

[0038] Based on the above embodiments, further optimizations can be made, such as... Figure 1 As shown, in order to facilitate the adjustment of the force of the compression spring 12, a detachable sealing plate is provided on the cabinet 1 near the first guide seat 11. When the sealing plate is opened, the nut on the top of the first guide support shaft 13 can be adjusted.

[0039] Based on the above embodiments, further optimization can be achieved by providing a protective layer on the surfaces of the lower drive roller 8 and the upper drive roller 5, which serves to prevent slippage and protect the sign.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
