Description

A cutting table for computer graphic design Technical Field

[0001] This utility model belongs to the field of graphic design technology, and in particular relates to a cutting table for computer graphic design. Background Technology

[0002] Graphic design involves layout and design on a computer and then printing. However, the design content is usually slightly smaller than the paper size to prevent some content from not being printed on the paper, resulting in some blank space at the edges of the paper. Therefore, the blank space needs to be trimmed.

[0003] Patent application CN202323215150.8 discloses a cutting table for computer graphic design, including a base plate. Two upright plates are symmetrically arranged on the upper surface of the base plate. A pressing device is fixedly arranged on the outer wall of the second upright plate, and a fixing device is arranged on the inner wall of the first upright plate. The pressing device includes a support plate fixedly arranged on the outer wall of the second upright plate, a movable motor fixedly arranged on the support plate, an adjusting threaded rod fixedly arranged on the output end of the movable motor, and one end of the adjusting threaded rod away from the output end of the movable motor rotatably arranged on the inner wall of the first upright plate. A screw and nut pair is threadedly connected to the adjusting threaded rod. A fixing plate is fixedly arranged below the screw and nut pair. A telescopic cylinder is symmetrically arranged below the fixing plate, and a fixing plate is fixedly arranged on the piston rod of the telescopic cylinder. A connecting plate is symmetrically arranged below the fixing plate, and a pressing roller is rotatably arranged between the connecting plates.

[0004] In existing technologies, paper is flattened using pressure rollers and blocks to ensure accurate subsequent cutting, but there are still shortcomings:

[0005] First, when the existing cutting table fixes the paper, the paper is slightly curved, which makes the paper not fit tightly with the worktable. This makes it easy for wrinkles to appear when the paper is clamped and fixed. This not only causes irreversible creases to the paper, but also affects the cutting accuracy of the paper in the future.

[0006] Secondly, the existing shearing table's fixing components lack flexibility, which means that the position of the fixing components cannot be adjusted according to the cutting part of the paper. As a result, it is impossible to press down and fix the paper near the edge of the cutting position, which makes the paper prone to loosening during subsequent cutting and reduces the cutting accuracy.

[0007] Finally, the existing shearing table's fixing components lack damping settings, which prevents the fixing components from effectively fixing the paper at a temporary angle when rotated to a certain angle according to actual fixing needs, thus affecting the precise pressing and fixing of the paper. Summary of the Invention

[0008] To overcome the shortcomings of existing technologies, this invention provides a cutting table for computer graphic design. Through the design of components such as folding airbags, the paper is held in place by the folding airbags and multiple conical holes, adhering to the upper surface of the worktable. Furthermore, after the paper is secured, the multiple conical protrusions fill the multiple conical holes, thus ensuring the flatness of the upper surface of the worktable.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a cutting table for computer graphic design includes a worktable. A plurality of first sliding rods are slidably arranged on the upper surface of the worktable. A second sliding rod is arranged on the upper surface of each first sliding rod. A fixing component is rotatably arranged on the outer circumference of each second sliding rod. A plurality of conical holes are provided on the upper surface of the worktable. A sealing chamber is provided outside the plurality of conical holes on the lower surface of the worktable. A through hole is provided on the inner bottom surface of the sealing chamber. A folding airbag is provided at the lower end of the through hole on the lower surface of the sealing chamber. A connecting frame is connected to the lower end of the folding airbag. The lower end of each first sliding rod is fixedly connected to the upper surface of the connecting frame.

[0010] Optionally, a movable ventilator is slidably disposed inside the sealed chamber, and a conical protrusion is slidably disposed inside each of the conical holes, with the lower end face of each conical protrusion being fixedly connected to the upper end face of the movable ventilator.

[0011] Optionally, the fixing component includes a rotating ring rotatably disposed on the outer circular surface of the second sliding rod, and a plurality of telescopic rods are disposed on the outer circular surface of the rotating ring, with a fixing block disposed at the output end of the plurality of telescopic rods.

[0012] Optionally, the fixing assembly further includes a lower pressure ring slidably disposed above the rotating ring on the outer circular surface of the second sliding rod, a first limiting block disposed at the top of the second sliding rod, and a first spring disposed on the outside of the second sliding rod between the first limiting block and the lower pressure ring.

[0013] Optionally, the lower end face of the pressure ring is provided with a plurality of first teeth, and the upper end face of the rotating ring is provided with a plurality of second teeth. The plurality of first teeth and second teeth mesh with each other. The outer circular surface of the second sliding rod is provided with a sliding groove, and a slider is slidably disposed inside the sliding groove. The slider is fixedly connected to the inner circular surface of the pressure ring.

[0014] Optionally, the lower end face of the movable ventilated plate is provided with a plurality of third sliding rods, one end of each third sliding rod passing through the lower end face of the sealing chamber and slidably connected to the sealing chamber, the bottom end of each sealing chamber is provided with a second limiting block, and a second spring is provided on the outside of each third sliding rod between the sealing chamber and the second limiting block.

[0015] Optionally, the elastic tension of the second spring is greater than that of the first spring.

[0016] Optionally, a push cylinder is provided on the lower end face of the connecting frame, and the output end of the push cylinder passes through the folded airbag and the connecting frame and is fixedly connected to the lower end face of the movable ventilated plate.

[0017] Optionally, a filter screen is provided at the upper port of the through hole, and the filter screen is slidably connected to the output end of the push cylinder.

[0018] Optionally, a cleaning window is provided on one side wall of the sealed chamber, a sealing plate is slidably disposed inside the cleaning window, and a sealing gasket is provided on the outer side wall of the sealing plate between the cleaning window and the sealing plate.

[0019] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0020] This invention, through the design of components such as conical holes, conical protrusions, and folding airbags, allows the paper to be adsorbed onto the upper surface of the worktable during the clamping process via the folding airbags and multiple conical holes. This effectively prevents creases caused by the slight curling of the paper during clamping, ensuring a tight fit between the paper and the upper surface of the worktable. This significantly improves the subsequent cutting accuracy. Furthermore, after the paper is fixed, the multiple conical protrusions fill the multiple conical holes, ensuring the flatness of the upper surface of the worktable and further improving the subsequent cutting accuracy of the paper.

[0021] This invention, through the arrangement of components such as the second sliding rod, rotating ring, and multi-section telescopic rod, enables the cutting table to rotate and adjust the position of the fixing blocks according to the size of the pattern on the paper. This allows multiple fixing blocks to fix and clamp the paper near the outer edge of the pattern when the paper is pressed down, effectively improving the stability and accuracy of the paper during subsequent cutting.

[0022] This invention, through the arrangement of components such as a first spring, a first tooth, and a second tooth, enables the rotation angle of the multi-section telescopic rod to be stably maintained when the multi-section telescopic rod and the fixing block are rotated, through the elastic tension of the first spring itself and the mutual meshing of the first and second teeth, thereby improving the accuracy of subsequent paper fixing.

Detailed Implementation

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Embodiment 1:

[0036] As shown in Figures 1, 2, 3, 4, 5, and 8, a cutting table for computer graphic design includes a worktable 10. Multiple first sliding rods 11 are slidably disposed on the upper end face of the worktable 10. Each first sliding rod 11 has a second sliding rod 12 disposed on its upper end face. A fixing component is rotatably disposed on the outer circular surface of each second sliding rod 12. Multiple conical holes 20 are provided on the upper end face of the worktable 10. The cross-sectional shape of the conical holes 20 is shown in Figure 6. The upper end is smaller than the lower end, which prevents paper scraps generated during cutting from entering the sealed chamber 21. It also increases the airflow velocity when external air enters the sealed chamber 21 through the conical holes 20, thereby allowing the multiple conical holes 20 to more firmly adhere the paper to the end face of the worktable 10, resulting in a more secure paper cutting surface. The surface is flattened, and a sealing chamber 21 is provided on the lower end face of the workbench 10 outside the multiple conical holes 20. A through hole 24 is provided on the inner bottom surface of the sealing chamber 21. A folded airbag 25 is provided at the lower end of the through hole 24 and on the lower end face of the sealing chamber 21. A connecting frame 28 is provided on the lower end face of the folded airbag 25. The lower end of each first sliding rod 11 is fixedly connected to the upper end face of the connecting frame 28. A multiple one-way valve 39 communicating with the outside is provided on the inner bottom surface of the folded airbag 25. The one-way valve 39 is provided so that when the folded airbag 25 is stretched by an external force, the external air cannot enter the interior of the folded airbag 25. When the folded airbag 25 is compressed by an external force, the air inside the folded airbag 25 will be discharged in time, thereby ensuring that the folded airbag 25 can maintain the balance of internal and external air pressure when compressed.

[0037] When the connecting frame 28 moves vertically downward, it will drive multiple first sliding rods 11 to move downward, thereby driving multiple fixing components to press down and fix the paper. During the above process, as the connecting frame 28 moves downward, it stretches the folding airbag 25, causing the pressure inside the folding airbag 25 to decrease, thus creating a pressure difference between the inside and outside of the folding airbag 25. At this time, external air will enter the sealing chamber 21 and the interior of the folding airbag 25 through multiple conical holes 20, thereby making the paper firmly adsorbed on the upper surface of the worktable 10 during the clamping and fixing process. Under the action of external air, it can also flatten the slightly curved paper.

[0038] Furthermore, as shown in Figures 1, 7, 9, and 10, the fixing component includes a rotating ring 14 rotatably mounted on the outer circular surface of the second sliding rod 12. Multiple telescopic rods 17 are provided on the outer circular surface of the rotating ring 14. These telescopic rods 17 are ordinary telescopic rods, which are existing technology and will not be elaborated upon in this solution. A fixing block 18 is provided at the output end of the telescopic rod 17. Through the rotational connection between the rotating ring 14 and the second sliding rod 12, and the telescopic characteristics of the telescopic rod 17 itself, each fixing block 18 can move at any angle and any horizontal position according to the requirements of the paper's fixing position, improving the flexibility of the fixing block 18. Multiple anti-slip protrusions 19 are provided on the lower end surface of the fixing block 18. The multiple anti-slip protrusions 19 effectively increase the friction between the fixing block 18 and the fixed paper, thereby improving the fixing stability of the paper by the fixing block 18.

[0039] Furthermore, as shown in Figures 7 and 9, the fixing assembly also includes a downward pressure ring 15 slidably disposed above the rotating ring 14 on the outer circular surface of the second sliding rod 12. A first limiting block 13 is disposed at the top of the second sliding rod 12. A first spring 16 is disposed between the first limiting block 13 and the downward pressure ring 15 on the outside of the second sliding rod 12. When the multiple rotating rings 14 move vertically downward with the connecting frame 28, the multiple rotating rings 14 drive the multiple telescopic rods 17 and fixing blocks 18 and other components to move vertically downward until the multiple fixing blocks 18 contact the upper end surface of the paper. At this time, through the elastic tension of the first spring 16 itself, the multiple rotating rings 14 can continue to move downward with the connecting frame 28. By compressing the multiple first springs 16, the downward pressure of the multiple fixing blocks 18 on the paper is further increased, thereby effectively improving the stable fixing of the paper while also providing a certain buffer stroke for the device and improving the service life of the device.

[0040] Furthermore, as shown in Figure 9, the lower end face of the pressure ring 15 is provided with multiple first teeth 31, and the upper end face of the rotating ring 14 is provided with multiple second teeth 32. The multiple first teeth 31 and second teeth 32 mesh with each other. The outer circular surface of the second sliding rod 12 is provided with a groove 33, and a slider 34 is slidably provided inside the groove 33. The slider 34 is fixedly connected to the inner circular surface of the pressure ring 15. The grooves 33 and 4 can prevent the pressure ring 15 from rotating with the rotating ring 14 under the meshing action of the first teeth 31 and second teeth 32 when the rotating ring 14 is rotated. The first teeth 31 and second teeth 32, together with the elastic tension of the first spring 16, make the rotation angle of the multi-section telescopic rod 17 fixed under the meshing action of the first teeth 31 and second teeth 32 after rotating a certain angle, without affecting the rotation of the rotating ring 14, thereby improving the stability of the multi-section telescopic rod 17 and other components after rotation.

[0041] Furthermore, as shown in Figures 4, 5, and 6, a movable vent plate 22 is slidably arranged inside the sealed chamber 21, and a conical protrusion 23 is slidably arranged inside each conical hole 20. The lower end face of each conical protrusion 23 is fixedly connected to the upper end face of the movable vent plate 22. The arrangement of the movable vent plate 22 and multiple conical protrusions 23 can fill and block multiple conical holes 20 after the paper is fixed, thereby ensuring the flatness of the upper end face of the workbench 10.

[0042] Furthermore, as shown in Figures 4 and 5, the lower end face of the movable ventilated plate 22 is provided with a plurality of third sliding rods 26. One end of each third sliding rod 26 passes through the lower end face of the sealing chamber 21 and is slidably connected to the sealing chamber 21. The bottom end of each sealing chamber 21 is provided with a second limiting block 40. A second spring 27 is provided between the outer side of each third sliding rod 26, the sealing chamber 21, and the second limiting block 40. The elastic tension of the second spring 27 is greater than the elastic tension of the first spring 16. The lower end face of the connecting frame 28 is provided with a push cylinder 29. The push cylinder 29 refers to a push cylinder with a certain pushing pressure and an adjustable stroke capability at the output end, such as an electric push cylinder or a hydraulic push cylinder. This is existing technology and will not be elaborated on in this solution. The output end of the push cylinder 29 passes through the folded airbag 25 and the connecting frame 28 and is fixedly connected to the lower end face of the movable ventilated plate 22.

[0043] In the initial state of the shearing table, because the elastic tension of the second spring 27 is greater than that of the first spring 16, the elastic tension of the multiple second springs 27 themselves creates elastic support between the second limiting block 40 and the sealing chamber 21. This causes the moving vent plate 22 to drive multiple conical protrusions 23 to abut against the inner bottom surface of the sealing chamber 21. When clamping and fixing the paper, the push cylinder 29 is activated, causing the output end of the push cylinder 29 to extend. Because the elastic tension of the second spring 27 is greater than that of the first spring 16, the push cylinder 29 will drive the connecting frame 28 to move downward, thereby driving multiple first sliding rods 11 to move vertically downward. The multiple first sliding rods 11 drive multiple rotating rings 14 and fixing blocks 18, etc., to press and fix the paper downward. During the process, the stretching of the folded airbag 25 forms an adsorption and fixation on the paper on the upper surface of the worktable 10. Subsequently, the output end of the push cylinder 29 continues to extend. During this process, the elastic tension of the multiple first springs 16 continues to increase after compression. After the balance of the elastic tension of the multiple first springs 16 and the multiple second springs 27 is broken, the multiple second springs 27 will maintain the balance of the elastic tension between the multiple first springs 16 and the multiple second springs 27 by compressing themselves. Under the action of the elastic tension of the multiple second springs 27, the second limit block 40 and the third sliding rod 26 will be pulled upward, thereby driving the moving vent plate 22 and the multiple conical protrusions 23 to fill and block the multiple conical holes 20, thereby ensuring the flatness of the upper surface of the worktable 10, which facilitates the subsequent cutting of the paper.

[0044] Furthermore, as shown in Figure 8, a filter screen 35 is provided at the upper port of the through hole 24. The filter screen 35 is slidably connected to the output end of the push cylinder 29. The filter screen 35 can effectively prevent tiny paper scraps that enter the sealed chamber 21 through the multiple conical holes 20 from entering the interior of the folded airbag 25 through the through hole 24, thus making it difficult to clean the tiny paper scraps inside the folded airbag 25 later, thereby ensuring the cleanliness of the interior of the folded airbag 25.

[0045] Furthermore, as shown in Figure 5, multiple limiting rods 30 are provided on the upper surface of the connecting frame 28 on the outside of the folding airbag 25. The length of the multiple limiting rods 30 is approximately equal to the height of the folding airbag 25 after folding. The setting of multiple limiting rods 30 can effectively protect the folding airbag 25 and prevent the connecting frame 28 from excessively compressing the folding airbag 25 when the output end of the push cylinder 29 retracts, thereby forming protection for the folding airbag 25. Each limiting rod 30 is provided with a buffer pad at its top. The setting of the buffer pad can effectively reduce the collision impact force between the limiting rod 30 and the lower surface of the sealing chamber 21.

[0046] In this solution, during the interconnected operation of the push cylinder and various components, the movement and stroke of each component are adjusted multiple times to ensure that the dimensions meet the multiple functions of the cutting table. The specific stroke of the push cylinder's output end can be addressed in actual production by using existing technologies such as controllers, sensors, or control circuits external to these drive components. These are not technical issues that this solution aims to solve, and therefore will not be elaborated upon further. Example 2:

[0047] Based on Embodiment 1, a further embodiment is provided, as shown in Figures 4 and 11. A cleaning window 36 is provided on one side wall of the sealing chamber 21. A sealing plate 37 is slidably disposed inside the cleaning window 36. The arrangement of the cleaning window 36 and the sealing plate 37 can effectively prevent some tiny paper scraps from entering the interior of the sealing chamber 21 through the multiple conical holes 20 in extreme cases. Thus, the interior of the sealing chamber 21 can be cleaned regularly by opening the sealing plate 37 and through the cleaning window 36, thereby ensuring the cleanliness of the interior of the sealing chamber 21 and preventing excessive accumulation of tiny paper scraps from affecting the filling of the multiple conical protrusions 23 into the multiple conical holes 20. A sealing gasket 38 is provided on the outer side wall of the sealing plate 37 between the cleaning window 36 and the sealing plate 37. The arrangement of the sealing gasket 38 can effectively increase the sealing between the cleaning window 36 and the sealing plate 37, thereby improving the overall sealing performance of the sealing chamber 21.
