DETAILED DESCRIPTION
[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0029] A fabric automatic folding mechanism is used for folding fabric 2 having a folding area 3 and a main area 4, wherein the automatic folding mechanism comprises: a workbench 1, on which the fabric 2 to be folded is movably arranged; a gripping member 5, which is arranged at the side of the workbench 1, and a limiting plate 6 is arranged on the gripping member 5, and the limiting plate 6 has a first movement mode of turning over relative to the workbench 1 synchronously with the gripping member 5, and a second movement mode of translation relative to the gripping member 5 and the workbench 1; a support plate 7, which is movably arranged on the workbench 1, and the support plate 7 has a first working state in which the end portion is flush with the workbench 1, and a second working state in which the support plate 7 at least partially overlaps with the workbench 1 in the vertical direction; when the support plate 7 is in the first working state, it is used for allowing the fabric 2 to move to one end of the folding area 3 to be flush with the end surface of the limiting plate 6, and can be in the second working state when the limiting plate is in the second movement mode of translation toward the workbench 1, and is used to make room for movement for the limiting plate.
[0030] Based on the above embodiments, this solution provides an exemplary structure, such as Figures 2 to 7 As shown, in the working process, the cloth 2 moves toward the grabbing member 5. The movement of the cloth 2 can be achieved by an additional power device in cooperation with a pressure plate (the power device and the pressure plate are not shown in the figure), which presses on the main area 4 of the cloth 2. During the movement of the cloth 2, the folding area 3 of the cloth 2 approaches the limit plate 6. When the cloth 2 moves to the point where one end of the folding area 3 is completely aligned with the end face of the limit plate 6, the grabbing member 5 begins to tightly grasp the end of the folding area 3. Subsequently, the grabbing member 5 performs a flipping motion relative to the workbench 1, driving the folding area 3 to be folded relative to the main area 4, and flipping the folding area 3 to the bottom of the main area 4. When the grabbing member 5 flips, the rotation axis of the grabbing member 5 coincides with the boundary line between the folding area 3 and the main area 4.
[0031] Next, the limiting plate 6 moves horizontally toward the workbench 1 and withdraws from between the folded fabrics 2. While the limiting plate 6 moves, the supporting plate 7 also moves toward the workbench 1 to prevent the supporting plate 7 from obstructing the horizontal movement of the limiting plate 6. Through this process, the precise folding operation of the fabric 2 is finally completed.
[0032] This solution simulates the process of manual folding operation by the grasping member 5 through the precise grasping and rotating action of one end of the folding area 3 of the fabric 2, effectively improving the folding accuracy of the folding area 3, thereby ensuring the high-precision requirements in the garment sewing process.
[0033] Based on the above technical solution, this solution also refines the automatic folding mechanism as follows:
[0034] The limiting plate 6 is provided with an intersecting first limiting surface 8 and a second limiting surface 9, and the end of the folding area 3 is movably abutted against the first limiting surface 8, so as to make one end of the folding area 3 flush with the first limiting surface 8, thereby ensuring the folding accuracy of the folding area 3 by the grasping member 5. A pressing member 10 is provided on the grasping member 5, and the pressing member 10 is movably arranged on one side of the limiting plate 6 and can be moved closer to or away from the second limiting surface 9. The pressing member 10 is used to press one end of the folding area 3 against the second limiting surface 9, so as to realize the grasping action of the grasping member 5 on the end of the folding area 3.
[0035] Preferably, the first limiting surface 8 and the second limiting surface 9 are arranged perpendicularly.
[0036] In addition, the grabbing member 5 includes: a first driving member 11, which is fixedly arranged on one side of the workbench 1; a rotating seat 12, which is connected to the output end of the first driving member 11, and the first driving member 11 is used to drive the rotating seat 12 to rotate; a second driving member 13, which is horizontally arranged on the rotating seat 12, and the output end of the second driving member 13 passes through the rotating seat 12 and is connected to the limit plate 6, and is used to drive the limit plate 6 to move in the horizontal direction; a third driving member 14, which is vertically arranged on the rotating seat 12, and the pressing member 10 is connected to the output end of the third driving member 14, and is used to drive the pressing member 10 to move closer to or away from the second limit surface 9.
[0037] After the folding area 3 of the cloth 2 moves to align with the first limiting surface 8, the third driving member 14 drives the pressing member 10 to move toward the second limiting surface 9, thereby firmly pressing one end of the folding area 3 between the pressing member 10 and the second limiting surface 9. Then, the first driving member 11 starts and drives the rotating seat 12 to rotate, so that the folding area 3 is folded to the lower end surface of the main body area 4. Afterwards, the second driving member 13 is responsible for pushing the limiting plate 6 to translate toward the workbench 1 and pull it out from the middle of the folded cloth 2, thereby completing the accurate folding process of the cloth 2. In the preferred embodiment, the first driving member 11 uses a motor as a driving source, and the second driving member 13 and the third driving member 14 are preferably cylinders as actuators.
[0038] Further preferably, a plurality of guide posts 15 are horizontally arranged on the limit plate 6 , a guide sleeve 16 is arranged on the rotating seat 12 , and the guide posts 15 are movably inserted in the guide sleeve 16 to provide guidance for the movement of the limit plate 6 .
[0039] When the second driving member 13 drives the limiting plate 6 to translate toward the working table 1, so that the limiting plate 6 is pulled out from the folded fabric 2, the friction between the limiting plate 6 and the folding area 3 is likely to cause the fabric 2 to wrinkle. Once this happens, the wrinkled part of the fabric 2 will be sewn out to form waste. In order to solve the above problem, the pressing member 10 of the present invention includes a pressing block 17 and a pressing sheet 18. The width of the pressing sheet 18 is smaller than that of the pressing block 17, and the pressing sheet 18 is The end surface facing the second limiting surface 9 should exceed the end surface of the pressing block 17. After the hemming area 3 is flipped and folded to the lower end of the main area 4, a part of the hemming area 3 will be clamped between the pressing sheet 18 and the limiting plate 6, and most of the hemming area 3 has a certain gap with the limiting plate 6 due to the height difference between the pressing block 17 and the end of the pressing sheet 18. The existence of this gap helps to reduce the friction between the hemming area 3 and the limiting plate 6 by reducing the actual contact area between the limiting plate 6 and the hemming area 3. In this way, when the limiting plate 6 operates in the second motion mode of translation toward the workbench 1, the friction between the hemming area 3 and the first limiting surface 8 can be effectively reduced to avoid unnecessary wrinkles.
[0040] Finally, the support plate 7 includes a first panel 19 and a second panel 20, a fourth driving member 21 is arranged on the workbench 1, a moving seat 22 is arranged at the output end of the fourth driving member 21, a fifth driving member 23 is vertically arranged on the moving seat 22, the first panel 19 is fixed on the moving seat 22, and the second panel 20 is connected to the output end of the fifth driving member 23.
[0041] The fourth driving member 21 is preferably designed as a linear guide rail, and its main function is to realize the translation of the first panel 19 and the second panel 20 on the surface of the workbench 1. The fifth driving member 23 is preferably driven by a cylinder, and its purpose is to drive the second panel 20 to move up and down in the vertical direction, so as to ensure that at least part of the support plate 7 can overlap with the surface of the workbench 1 in the vertical direction, and achieve the expected use effect.
