[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The present invention provides a parachute multi-layer sewing auxiliary fixing device, the structure of which is as follows: Figure 1 - Figure 2 As shown, it includes a supporting mechanism 1, a limiting mechanism 2 and a bending mechanism 3.

[0021] The supporting mechanism 1 includes a supporting plate 11 .

[0022] The limiting mechanism 2 includes two limiting plates 21 arranged on the supporting plate 11 .

[0023] The bending mechanism 3 includes a plurality of through holes 31 provided on one of the limiting plates 21, and the plurality of through holes 31 are arranged at intervals along the height direction of the limiting plate 21, a bending plate 32 is slidably inserted in the through holes 31, and a fixing assembly 33 for fixing the bending plate 32 to the limiting plate 21 is provided on the limiting plate 21, and a gap is provided between the end of the bending plate 32 and the other limiting plate 21, a first bending cavity 34 is formed between the two limiting plates 21, and a second bending cavity 35 is formed between the two adjacent bending plates 32, and the first bending cavity 34 and the second bending cavity 35 are used for allowing cloth to pass through in sequence.

[0024] When in use, the support plate 11 serves as the basic support of the entire device, providing a stable platform to ensure that the device does not shake or move during the sewing process. Two limit plates 21 are installed on the support plate 11, and the relative positions between them are fixed. During the sewing process, the limit plates 21 play a role in limiting and guiding the passing cloth. One of the limit plates 21 is provided with a plurality of through holes 31 arranged at intervals in the height direction, and a bending plate 32 is slidably inserted in each through hole 31. These bending plates 32 can slide up and down in the through holes 31 to adjust the size and shape of the bending cavity 34. The fixing assembly 33 on the limit plate 21 is used to fix the position of the bending plate 32. When the bending plate 32 is adjusted to the desired position, the fixing assembly 33 fixes it to prevent the bending plate 32 from moving during the sewing process. A bending cavity 34 for the cloth to pass through is formed between the two limit plates 21 and between the adjacent bending plates 32. When the cloth passes through the bending cavity 34, it will be guided and folded by the bending plate 32 to form a specific multi-layer structure. A gap is provided between the end of the bending plate 32 and the other limiting plate 21, and the gap allows the cloth to smoothly enter and leave the bending cavity 34. At the same time, the size of the gap can also affect the folding degree and sewing effect of the cloth.

[0025] In the present invention, through the synergistic effect of the limiting mechanism 2 and the bending mechanism 3, the cloth can maintain an accurate position and shape during the sewing process, which helps to improve the sewing accuracy, ensure that the sizes of various parts of the parachute are consistent, and improve the performance and reliability of the parachute. The bending plate 32 can slide in the through hole 31 and be fixed by the fixing component 33, so that the size and shape of the first bending cavity 34 and the second bending cavity 35 can be adjusted according to different cloth thicknesses and sewing requirements. This adjustability makes the device suitable for sewing parachutes of different specifications, thereby improving the versatility of the device.

[0026] To fix the bent plate 32, please refer to Figure 1 In a preferred embodiment, the fixing assembly 33 includes a first plug hole 331 provided on the limiting plate 21, a plug rod 332 is inserted into the first plug hole 331, and a second plug hole 333 for the plug rod 332 to pass through is provided on the bending plate 32.

[0027] When in use, when the fixing operation is not performed, the insertion rod 332 is not inserted into the first insertion hole 331 and the second insertion hole 333. The bending plate 32 is in a movable state and can slide freely in the through hole 31 to adjust the size and shape of the bending cavity 34. According to the thickness of the parachute cloth and the sewing requirements, the operator adjusts the size of the bending cavity 34 by sliding the bending plate 32 in the through hole 31. When adjusted to a suitable position, the second insertion hole 333 on the bending plate 32 is aligned with the first insertion hole 331 on the limiting plate 21. Insert the insertion rod 332 into the first insertion hole 331 on the limiting plate 21. Since the first insertion hole 331 and the second insertion hole 333 are already aligned, the insertion rod 332 can smoothly pass through the first insertion hole 331 and enter the second insertion hole 333 on the bending plate 32. After the insertion rod 332 passes through the first insertion hole 331 and the second insertion hole 333, the bending plate 32 is fixed to the limiting plate 21. At this time, the bending plate 32 can no longer slide in the through hole 31 and remains in a fixed position.

[0028] To improve the stability of the insertion rod 332, please refer to Figure 1 In a preferred embodiment, a first spring 334 is sleeved on the insertion rod 332, one end of the first spring 334 is connected to the insertion rod 332, and the other end of the first spring 334 is connected to the limit plate 21. The first spring 334 is in a stretched state, and the first spring 334 causes the insertion rod 332 to have a tendency to slide toward the bending plate 32.

[0029] When in use, when the bending plate 32 needs to be fixed, the bending plate 32 is adjusted to a suitable position so that the first insertion hole 331 on the limiting plate 21 is aligned with the second insertion hole 333 on the bending plate 32. In this process, due to the tension of the first spring 334, the insertion rod 332 always tends to slide toward the bending plate 32. Due to the tension of the first spring 334, the insertion rod 332 will be more easily aligned with the first insertion hole 331 and the second insertion hole 333. When the holes are aligned, the insertion rod 332 will automatically slide toward the bending plate 32 under the tension of the spring and be inserted into the two holes. After the insertion rod 332 is inserted into the first insertion hole 331 and the second insertion hole 333, the bending plate 32 and the limiting plate 21 are fixed together. At this time, the first spring 334 is still in a stretched state and continues to apply tension to the insertion rod 332 to ensure that the insertion rod 332 is firmly inserted into the hole and will not accidentally fall out.

[0030] To adjust the bending width of the fabric, please refer to Figure 1 In a preferred embodiment, the two limit plates 21 are both slidably connected to the support plate 11 , and the support plate 11 is provided with an adjustment component 4 for adjusting the distance between the two limit plates 21 .

[0031] When in use, for parachute fabrics of different thicknesses, the spacing of the limit plates 21 needs to be adjusted to ensure that the fabric can pass smoothly and remain stable during the sewing process. Thicker fabrics require larger spacing, while thinner fabrics can use smaller spacing. Different sewing processes may have specific requirements for the folding method and sewing path of the fabric, which may also require adjusting the spacing of the limit plates 21 to achieve. Once the appropriate spacing is adjusted, the adjustment component 4 stops working. At this time, the two limit plates 21 maintain a stable position on the support plate 11, providing accurate limiting and guiding for the multi-layer sewing of the parachute fabric. During the entire sewing process, the spacing of the limit plates 21 will not change unexpectedly due to external interference, ensuring the stability of the sewing quality.

[0032] To adjust the distance between the two limit plates 21, please refer to Figure 1 In a preferred embodiment, the adjustment assembly 4 includes a double-headed screw 41 rotatably connected to the support plate 11, and both ends of the double-headed screw 41 pass through two limit plates 21 respectively, and both limit plates 21 are provided with threaded holes 42 adapted to the double-headed screw 41.

[0033] When in use, the operator rotates the double-ended screw 41 manually or automatically. The double-ended screw 41 is a screw with opposite thread directions at both ends. When the screw rotates, an axial displacement force is generated due to the effect of the thread. Since the two ends of the double-ended screw 41 pass through the two limit plates 21 respectively, and the limit plates 21 are provided with threaded holes 42 adapted to the double-ended screw 41, when the screw rotates, the two limit plates 21 will move along the axial direction of the screw under the action of the screw. If the double-ended screw 41 rotates clockwise, according to the setting of the thread direction, one limit plate 21 will move in one direction and the other limit plate 21 will move in the opposite direction, thereby increasing or decreasing the distance between the two; if the double-ended screw 41 rotates counterclockwise, the movement direction of the limit plate 21 is opposite. Once the appropriate distance is adjusted, the double-ended screw 41 stops rotating. Due to the self-locking effect of the thread, the limit plate 21 will remain in the current position and will not be accidentally displaced due to the movement of the fabric or slight external vibration. During the entire process of sewing the multiple layers of the parachute, the adjustment assembly 4 can ensure that the spacing between the limiting plates 21 is stable, thus providing reliable limiting and guiding for sewing.

[0034] To reduce the possibility of the double-ended screw 41 rotating loose, please refer to Figure 1 In a preferred embodiment, the end of the double-headed screw 41 is fixedly connected to an anti-loosening gear 43, and the support plate 11 is provided with a slot 44, in which an anti-loosening tooth block 45 meshing with the anti-loosening gear 43 is clamped.

[0035] When in use, during the multi-layer sewing process of the parachute, due to the movement of the fabric, the vibration of the equipment or other external factors, the double-headed screw 41 may have a tendency to rotate slightly, thereby causing the spacing of the limit plates 21 to change, affecting the precision and quality of sewing. In order to prevent the double-headed screw 41 from loosening, the anti-loosening tooth block 45 is pushed into the slot 44 so that it is meshed with the anti-loosening gear 43. When the anti-loosening tooth block 45 is inserted into the slot 44 and meshed with the anti-loosening gear 43, it will prevent the anti-loosening gear 43 from rotating. In this way, the double-headed screw 41 can be effectively prevented from loosening under the influence of external factors, ensuring that the spacing of the limit plates 21 is stable, thereby ensuring the stability and precision of the parachute fabric during the sewing process.

[0036] To adjust the distance between the bending plate 32 and the limiting plate 21, please refer to Figure 1 In a preferred embodiment, a plurality of second insertion holes 333 for the insertion rods 332 to pass through are provided on the bending plate 32 at intervals along the sliding direction of the bending plate 32 .

[0037] When in use, according to the thickness of the parachute cloth, the folding requirements and the sewing process, the operator adjusts the size of the bending cavity 34 by sliding the bending plate 32 in the through hole 31. Since a plurality of second plug holes 333 are provided on the bending plate 32 at intervals along the sliding direction, more options are provided for adjustment. When the bending plate 32 is adjusted to a roughly suitable position, the operator can observe the state of the cloth in the bending cavity 34 and further fine-tune the position of the bending plate 32. By setting a plurality of second plug holes 333, the position that best meets the current cloth and sewing requirements can be found more accurately. Once the appropriate position is determined, the first plug hole 331 on the limiting plate 21 is aligned with a corresponding second plug hole 333 on the bending plate 32. Then, the insertion rod 332 is inserted into the first plug hole 331 and the selected second plug hole 333, and the bending plate 32 is fixed at the current position by the fixing component 33.

[0038] To make the fabric slide more smoothly, please refer to Figure 2 In a preferred embodiment, a telescopic rod 5 with a supporting function is provided at the end of the bending plate 32 , a guide wheel 51 is provided at the end of the telescopic rod 5 , and a gap is provided between the guide wheel 51 and the limiting plate 21 .

[0039] During use, as the cloth enters, the cloth may exert a certain pressure on the end of the bending plate 32. At this time, the telescopic rod 5 will automatically adjust its length according to the pressure to provide support. The telescopic nature of the telescopic rod 5 enables it to adapt to cloths of different thicknesses and different pressure conditions. The support function of the telescopic rod 5 can prevent the bending plate 32 from deforming or displacing under the pressure of the cloth. It ensures that the bending plate 32 always remains in the correct position, maintains the shape and size of the bending cavity 34, and provides a stable structure for the folding and sewing of the cloth. There is a gap between the guide wheel 51 installed at the end of the telescopic rod 5 and the limit plate 21. When the cloth moves in the bending cavity 34, the guide wheel 51 contacts the cloth. The rolling of the guide wheel 51 can greatly reduce the friction between the cloth and the end of the bending plate 32 and the limit plate 21, so that the cloth can pass through the bending cavity 34 more smoothly, reducing the wear and resistance of the cloth. The guide wheel 51 can also play a role in guiding the cloth. It can ensure that the cloth moves in the bending cavity 34 in the correct direction, avoid the cloth from being deflected or twisted when passing through the bending cavity 34, and improve the precision and quality of sewing.

[0040] In order to make the telescopic rod 5 have a good supporting function, please refer to Figure 2 In a preferred embodiment, the telescopic rod 5 includes a first rod body 52 and a second rod body 53, the first rod body 52 is arranged at the end of the bending plate 32, the second rod body 53 is slidably connected to the first rod body 52 along the length direction of the first rod body 52, and a second spring is sleeved on the first rod body 52 and the second rod body 53, one end of the second spring is connected to the first rod body 52, and the other end of the second spring is connected to the second rod body 53, and the second spring is in the original length state.

[0041] When in use, when the cloth enters the bending cavity 34 formed by the two limiting plates 21 and the bending plate 32, the cloth may generate pressure on the end of the bending plate 32. This pressure will be transmitted to the telescopic rod 5. As the pressure exerted by the cloth acts on the end of the bending plate 32, the pressure will push the second rod 53 to slide along the length direction of the first rod 52. Since the second rod 53 and the first rod 52 are slidably connected, the second rod 53 can move relative to the first rod 52. During the sliding process of the second rod 53, the second spring sleeved on the first rod 52 and the second rod 53 will be compressed. One end of the second spring is connected to the first rod 52, and the other end is connected to the second rod 53. When the second rod 53 moves relative to the first rod 52, the length of the spring will change. As the spring is compressed, the spring will generate a reverse elastic force. This elastic force will act on the second rod 53, and will be transmitted to the end of the bending plate 32 through the second rod 53, providing support force for the bending plate 32. This supporting force can balance the pressure of the fabric on the bending plate 32, preventing the bending plate 32 from deforming or shifting under pressure. Due to the elastic properties of the spring, the telescopic rod 5 can automatically adjust its length according to the different pressures applied by the fabric. When the pressure is high, the second rod 53 will slide further, the spring will be compressed more, and a greater supporting force will be generated; when the pressure is low, the spring will gradually return to its original length, and the second rod 53 will also move to its initial position. This automatic adjustment capability enables the telescopic rod 5 to adapt to fabrics of different thicknesses and different sewing conditions, always providing appropriate supporting force for the bending plate 32, and maintaining the shape and stability of the bending cavity 34.

[0042] The embodiment of the present invention also discloses a parachute multi-layer sewing auxiliary fixing method, comprising the following steps: A. Use the adjustment component 4 to adjust the distance between the two limit plates 21; B. Adjust the position of the bending plate 32 and fix the bending plate 32 using the fixing assembly 33; C. Bend the fabric and pass it through the bending cavity 34.

[0043] In order to better understand the present invention, the following Figure 1 - Figure 2The working principle of a device for controlling the multi-layer sewing of a parachute according to the technical solution of the present invention is described in detail: the support plate 11 serves as the basic support of the entire device, providing a stable platform to ensure that the device does not shake or move during the sewing process. Two limit plates 21 are installed on the support plate 11, and the relative position between them is fixed. During the sewing process, the limit plates 21 play a role in limiting and guiding the passing cloth. One of the limit plates 21 is provided with a plurality of through holes 31 arranged at intervals in the height direction, and a bending plate 32 is slidably inserted in each through hole 31. These bending plates 32 can slide up and down in the through holes 31 to adjust the size and shape of the bending cavity 34. The fixing assembly 33 on the limit plate 21 is used to fix the position of the bending plate 32. When the bending plate 32 is adjusted to the desired position, the fixing assembly 33 fixes it to prevent the bending plate 32 from moving during the sewing process. A bending cavity 34 for the cloth to pass through is formed between the two limit plates 21 and between adjacent bending plates 32. When the fabric passes through the bending cavity 34, it is guided and folded by the bending plate 32 to form a specific multi-layer structure. A gap is provided between the end of the bending plate 32 and the other limiting plate 21, and the gap allows the fabric to smoothly enter and leave the bending cavity 34. At the same time, the size of the gap can also affect the folding degree of the fabric and the sewing effect.

[0044] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
