Description

Technical Field

[0001] The present invention belongs to the technical field of parachute cord processing, and particularly relates to a parachute cord processing device. Background Art

[0002] Whether it is an aircraft parachute, a drone parachute, or a human parachute, a common major component is the parachute cord. The processing quality of the parachute cord, that is, the accuracy of the parachute cord length, directly affects the shape of the parachute canopy, and further affects its performance after deployment. Therefore, it can be said that the parachute cord is one of the most critical factors determining the performance of the parachute. According to the relevant regulations of the standard, in the production of parachute cords by factories, a production method should be adopted in which a certain tension is applied to both ends of the parachute cord, and the length of the parachute cord is determined under this tension. During design, the length data of the parachute cord with a specified tension is given; during production, according to the tension given in the design, the length of the parachute cord is marked and cut under this tension; during the finished product inspection, the length of the parachute cord is also measured under the tension given in the design to determine whether the product is qualified.

[0003] Currently, the processing of parachute cords is usually completed by means of a relatively simple scribing table. This scribing table mainly consists of a flat, long and straight tabletop with dimensions of about 8×1 meters and a metal pin fixed at one end of the tabletop and vertically arranged with a height of about 30 centimeters. Its working principle is to first cut out a section of parachute cord whose length is significantly greater than the design requirement, fold one end back and fix it with a buttonhole to form a cord buckle, pass the end with the cord buckle through the metal pin and fix it, straighten the other end of the parachute cord and apply an appropriate tension, measure the required length and then make a scribing mark, and finally complete the cutting according to the scribing mark. This method simplifies the structure and to a certain extent reduces the complexity of parachute cord production.

[0004] However, this method essentially only assists in completing the scribing work, and the subsequent cutting work still needs to be carried out separately by manual labor. Therefore, there are problems of low production efficiency and high dependence on manual labor. Summary of the Invention

[0054] Please refer to Figure 1 and Figure 2, the present invention provides a processing device for umbrella ropes, comprising: a wire reel 10 on which an umbrella rope roll is loaded; a rope releasing device 20 around which the umbrella rope is wound after being pulled out from the umbrella rope roll; an umbrella rope cutting device 30 arranged on one side of the rope releasing device 20 for cutting the umbrella rope passing through it; and an umbrella rope clamping device 40 movably arranged on the side of the umbrella rope cutting device 30 away from the rope releasing device 20. Wherein, the umbrella rope clamping device 40 can move to a first position close to the umbrella rope cutting device 30 to clamp the umbrella rope released by the rope releasing device 20; the umbrella rope clamping device 40 can move to a second position away from the umbrella rope cutting device 30, and the umbrella rope cutting device 30 cuts the umbrella rope connected between the umbrella rope clamping device 40 and the rope releasing device 20. It should be noted that the first position is the position for clamping the umbrella rope and is generally fixed; the second position is the position for pulling and moving after clamping the umbrella rope, which is determined according to the different tension requirements and required lengths of different umbrella ropes.

[0055] Specifically, the umbrella rope is pulled out from the umbrella rope roll on the wire reel 10 and wound around the rope releasing device 20. During the processing of the umbrella rope, after the device is started, the umbrella rope clamping device 40 moves from the initial position to the first position close to the umbrella rope cutting device 30 to clamp the umbrella rope released by the rope releasing device 20. Subsequently, the umbrella rope clamping device 40 drives the umbrella rope to move to the second position away from the umbrella rope cutting device 30. After the umbrella rope clamping device 40 reaches the second position, the umbrella rope cutting device 30 cuts the umbrella rope connected between the umbrella rope clamping device 40 and the rope releasing device 20 to complete the cutting of a section of the umbrella rope. After the cutting is completed, the umbrella rope clamping device 40 repeats the above actions again to clamp and cut the next section of the umbrella rope, and so on, realizing the continuous and automated processing of the umbrella rope.

[0056] Please refer to Figures 3 to 7 , in some embodiments, the rope releasing device 20 is used for winding and releasing the umbrella rope, comprising: a bracket 21; a friction wheel 22 rotatably arranged on the bracket 21 around which the umbrella rope is wound; and a brake 23 fixedly arranged on the bracket 21 for changing the rotational resistance of the friction wheel 22. It should be noted that changing the rotational resistance of the friction wheel 22 aims to adjust the tension of the umbrella rope pulled out from the rope releasing device 20 to meet the processing requirements.

[0057] Specifically, when it is necessary to release the parachute cord, the operator adjusts the rotational resistance of the friction wheel 22 to an appropriate magnitude through the brake 23. Subsequently, the friction wheel 22 starts to rotate under the combined action of the pulling force for releasing the parachute cord by the parachute cord clamping device 40 and its own rotational resistance, and the parachute cord is gradually released according to the set resistance conditions. During the release process, the operator can adjust the rotational resistance at any time through the brake 23 according to actual requirements to precisely control the release speed and tension of the parachute cord. When the parachute cord is released to the required length, the friction wheel 22 is made stationary again through the brake 23 to complete this rope release operation. The rope release device 20 of this embodiment can continuously release as needed, reducing the cumbersome steps such as repeated pre-cutting, scribing, and cutting in traditional processing, greatly improving the processing efficiency, and meeting the requirements for high-efficiency processing in large-scale production. At the same time, by precisely controlling the rotational resistance of the friction wheel 22, the release length and the rope body tension of the parachute cord can be accurately controlled, avoiding the redundant part generated by pre-cutting an overly long parachute cord segment, effectively reducing the waste of raw materials, improving the utilization rate of raw materials, thereby reducing the production cost, and achieving the conservation and utilization of resources.

[0058] Furthermore, the friction wheel 22 is made of rubber.

[0059] It should be explained that the friction wheel 22 should have a certain elasticity to increase the contact area with the parachute cord while preventing damage to the parachute cord. Therefore, it is considered to select rubber as the material directly contacting the parachute cord. Preferably, in this embodiment, neoprene with excellent resilience and good adhesion to fabrics is selected as the material for the friction wheel 22 to contact the parachute cord.

[0060] Furthermore, the friction wheel 22 is circumferentially provided with a wheel groove 221, and the wheel groove 221 is arranged in a spiral shape around the central axis of the friction wheel 22, and the parachute cord is wound along the wheel groove 221.

[0061] It can be understood that during the processing of the parachute cord, in order to ensure that the parachute cord can be stably and orderly wound and released, and at the same time ensure the accuracy of tension control, the friction wheel 22 of this embodiment is provided with a spiral wheel groove 221, aiming to further reduce problems such as processing errors caused by the slippage or uneven tension of the parachute cord. Specifically, the parachute cord is wound around the friction wheel 22 along the path of the spiral wheel groove 221. In the initial state, the friction wheel 22 is stationary, and the parachute cord is in a tensioned state waiting to be released; when it is necessary to release the parachute cord, the brake 23 is operated to reduce the rotational resistance of the friction wheel 22, and the friction wheel 22 starts to rotate, and the parachute cord is orderly released along the spiral wheel groove 221; due to the design of the rubber friction wheel 22 and the spiral wheel groove 221, sufficient friction is maintained between the parachute cord and the friction wheel 22 to ensure that the parachute cord has no slippage during the release process, thereby ensuring the stability of the parachute cord tension.

[0062] It should be noted that in order to ensure that the parachute cord does not slip on the friction wheel 22 and to ensure the stability of its tensioning effect, the number of winding turns required to ensure no slip between the parachute cord and the friction wheel 22, that is, the number of turns of the wheel groove 221, and the diameter of the friction wheel 22 should be calculated. The following is an analysis of this.

[0063] The analysis of the friction force of the rope wound around the cylinder is carried out according to the following formula:

[0064]

[0065] In the formula:

[0066] f — is the friction force between the rope and the cylinder (i.e., the friction wheel 22);

[0067] F0 — is the pulling force in the direction opposite to the rope pulling direction;

[0068] l — is the length of the rope wound around the cylinder;

[0069] μ — is the friction coefficient between the rope and the cylinder;

[0070] R — is the radius of the cylinder.

[0071] At this time, the number of winding turns m is introduced, then there is:

[0072]

[0073] It can be seen from the above formula that when the rope is wound around the cylinder for more than one turn, the magnitude of the maximum friction force f that can be generated between the rope and the cylinder is only directly related to the number of winding turns m, and has no direct relation with the radius of the cylinder and the length of the rope wound around the cylinder. That is, after the required friction force magnitude is given, the required number of winding turns can be calculated, and the radius of the cylinder and the length of the rope wound around the cylinder are related to each other. Once one is selected, the other parameter can be determined. After determining the number of winding turns m and the length l of the rope wound around the cylinder, the radius R of the cylinder is determined by the relational formula and is thus determined.

[0074] Therefore, first calculate the required number of winding turns m according to f = F0(e m2πμ -1). According to the design index, the parachute cord requires a maximum tension of 200 N. Taking 1.5 as the safety factor, we get F = 300 N, that is, the rope releasing device 20 should be able to provide a tension of 300 N. Since the required tension is the friction force between the rope and the cylinder, that is, f = F = 300 N. The F 0的 pulling force is mainly generated by the mechanical friction during rope pulling and the rotational inertia of the spool. Take F0 = 1 N. Take the friction coefficient between the parachute cord and rubber as 0.4, that is, μ = 0.4. Substitute the above parameters into f = F0(e m2πμ-1), it is calculated that m≈2.27, and m = 3 is taken. At this time, the friction force between the rope and the cylinder can be about 1874.3N, that is, F = f = 1874.3N, which has far exceeded the design requirements.

[0075] Furthermore, the wheel groove 221 is arranged around the central axis of the friction wheel 22 for at least 3 turns, and the umbrella rope winds around the friction wheel 22 for at least three turns. A friction force of about 1874.1N can be generated between the umbrella rope and the friction wheel 22, which is sufficient to meet the tension requirement of the umbrella rope. Preferably, to ensure that the umbrella rope can smoothly wind out from the other end of the wheel groove 221 after entering from one end of the wheel groove 221, the grooving should not affect the entering and winding out umbrella ropes. In this embodiment, the number of turns of the spiral groove-shaped wheel groove 221 is set to 3.5 turns.

[0076] Furthermore, the diameter of the friction wheel 22 is 120mm. It should be explained that the diameter of the friction wheel 22 in this embodiment is selected according to the following formula:

[0077]

[0078] Among them, when the diameter is too small, the curling degree of the rope is too large, which is likely to have an adverse effect on its braided structure. Especially after applying tension, irreversible deformation is more likely to occur. In addition, when the length of the rope wound around the cylinder is long, it is beneficial to the premature release of stress in the umbrella rope. Considering the above factors, it is determined that l≥1000mm. According to l = 1000mm and m = 3, according to It is calculated that R = 53mm. Considering that the friction wheel 22 needs to be grooved with a spiral groove to better accommodate and guide the umbrella rope, and at the same time the rubber material has a certain stretchability, R = 60mm is taken. Therefore, in this embodiment, the radius of the friction wheel 22 is selected as 60mm, and the diameter is 120mm.

[0079] Furthermore, the wheel groove 221 is a semi-circular spiral groove with a diameter of 8mm. It should be explained that the grooving width of the wheel groove 221 should be determined according to the diameter of the umbrella rope to ensure that the umbrella rope is completely accommodated. According to the processing umbrella rope diameter range of 2 - 5mm, the diameter of the wheel groove 221 is selected as 8mm in this embodiment, which can stably accommodate most of the umbrella ropes.

[0080] Furthermore, the pitch of the wheel groove 221 around the central axis of the friction wheel 22 is 18mm.

[0081] Furthermore, it also includes a hub 24 and a hub cover plate 25. The friction wheel 22 is arranged between the hub 24 and the hub cover plate 25, and the hub 24 and the hub cover plate 25 are respectively rotatably connected to the bracket 21.

[0082] Further, a plurality of fixing posts 241 are arranged axially on one side of the hub 24 facing the hub cover plate 25, a plurality of first fixing holes 251 corresponding to the plurality of fixing posts 241 are arranged axially on the hub cover plate 25, and a plurality of second fixing holes 222 corresponding to the plurality of fixing posts 241 are arranged axially on the friction wheel 22; the plurality of fixing posts 241 correspondingly pass through the plurality of first fixing holes 251 and the plurality of second fixing holes 222; a first rotating shaft 242 is coaxially arranged on one side of the hub 24 away from the hub cover plate 25, a second rotating shaft 252 is coaxially arranged on one side of the hub cover plate 25 away from the hub 24, and the first rotating shaft 242 and the second rotating shaft 252 are respectively rotatably connected to the bracket 21.

[0083] Optionally, the hub 24, the hub cover plate 25, and the friction wheel 22 are coaxially arranged. Optionally, four fixing posts 241 are provided, and the four fixing posts 241 are evenly arranged around the central axis of the hub 24.

[0084] Further, a brake disc 231 is arranged on the first rotating shaft 242 and / or the second rotating shaft 252. The brake 23 includes a driver and a brake caliper 232, and the driver is used to drive the brake caliper 232 to clamp or release the brake disc 231. It should be noted that the brake 23 in this embodiment is a disc brake 23, and the following is the analysis of the parameter requirements for the brake 23 in this embodiment.

[0085] In this embodiment, it is determined that the diameter of the friction wheel 22 is 120 mm, and the design requires that the maximum tension that the friction wheel 22 can provide for the parachute cord is 300 N. According to the calculation formula of torque:

[0086] τ = r × F

[0087] In the formula:

[0088] τ — is the torque;

[0089] r — is the distance from the acting point of the force to the rotation center, which is 60 mm here;

[0090] F — is the force received, which is 300 N;

[0091] It is calculated that the maximum torque generated by the friction wheel 22 is 18 N·m. Therefore, the braking torque provided by the brake 23 should be at least greater than or equal to 18 N·m. However, in addition to the requirement of the maximum torque, since the required tension of parachute cords of different specifications is different, the braking torque of the brake 23 should also be freely adjustable between 0 - 18 N·m to meet the requirements.

[0092] Further, a threaded hole is axially provided at one end of the fixing post 241 away from the wheel hub 24. The threaded hole is in threaded fit with a fixing screw, and the diameter of the nut of the fixing screw is larger than the diameter of the first fixing hole 251; alternatively, an external threaded portion is circumferentially provided at one end of the fixing post 241 away from the wheel hub 24. The external threaded portion is in threaded fit with a fixing nut, and the outer diameter of the fixing nut is larger than the diameter of the first fixing hole 251. In this embodiment, by the cooperation of the fixing screw and the threaded hole, a receiving groove 253 for receiving the nut of the fixing screw is provided on the side of the wheel hub cover plate 25 away from the wheel hub 24.

[0093] Please refer to Figures 8 to 15 , in some embodiments, the umbrella cord cutting device 30 includes: a mounting base 31; an umbrella cord cutter 32 slidably connected to the mounting base 31 in the vertical direction; a pressing rod 33 rotatably connected to the mounting base 31, and the pressing rod 33 is movably connected to the umbrella cord cutter 32; wherein, the mounting base 31 is provided with an initial station and a cutting station, and the pressing rod 33 drives the umbrella cord cutter 32 to move between the initial station and the cutting station. In this embodiment, through the movable connection between the pressing rod 33 and the umbrella cord cutter 32, the rotation of the pressing rod 33 is converted into the sliding of the umbrella cord cutter 32 in the vertical direction. The operator only needs to apply a relatively small force to the pressing rod 33, and the cutting of the umbrella cord can be completed by the lever principle and mechanical transmission, reducing the physical consumption of the operator, lowering the labor intensity, and improving the comfort and sustainability of the work.

[0094] Specifically, in the initial state, the umbrella cord cutter 32 is located at the initial station of the mounting base 31, and the pressing rod 33 is in the natural position. At this time, the umbrella cord cutter 32 is relatively stationary with the mounting base 31, waiting for the placement and cutting instructions of the umbrella cord. When starting the cutting, the operator applies a downward pressure to the pressing rod 33, and the pressing rod 33 starts to rotate around its rotation connection point with the mounting base 31. During the rotation process, the pressing rod 33 drives the umbrella cord cutter 32 to move downward along the vertical direction, gradually approaching the cutting station. At the same time, the cutting blade 322 of the umbrella cord cutter 32 starts to contact and squeeze the umbrella cord. As the pressing rod 33 continues to rotate, the umbrella cord cutter 32 reaches the cutting station, and the cutting blade 322 applies sufficient force to the umbrella cord to complete the cutting action. After the cutting is completed, the operator lifts the pressing rod 33 back to the initial position, and the umbrella cord cutter 32 also returns to the initial station, and the umbrella cord cutting device 30 returns to the initial state, ready for the next cutting.

[0095] Further, the push rod 33 includes: a push rod 33 main body, and a rotating portion 331, a connecting portion 332, and a holding portion 333 provided on the push rod 33 main body. The rotating portion 331 and the holding portion 333 are respectively provided at both ends of the push rod 33 main body, and the connecting portion 332 is provided between the rotating portion 331 and the holding portion 333. Among them, the rotating portion 331 is rotatably connected to the mounting base 31, and the connecting portion 332 is movably connected to the umbrella rope cutter 32. Optionally, the holding portion 333 is provided with a handle for easy grasping by the operator, and the surface layer of the handle can be made of rubber or silica gel material.

[0096] Further, the umbrella rope cutting device 30 further includes a connecting rod 34. One end of the connecting rod 34 is rotatably connected to the connecting portion 332, and the other end is rotatably connected to the umbrella rope cutter 32. It can be understood that during the rotation process of the push rod 33, the connecting rod 34 can uniformly convert the rotational motion into the linear motion of the umbrella rope cutter 32, reducing the jitter and jamming phenomena during the motion process, and improving the stability of the cutting action and the consistency of the umbrella rope cutting length.

[0097] Specifically, the length of the push rod 33 is in the range of 600 mm - 900 mm, and the connecting portion 332 is provided at one-tenth of the length of the push rod 33 from the rotating portion 331 to the holding portion 333; the rotation angle of the push rod 33 driving the umbrella rope cutter 32 from the initial position to the cutting position is 30°. Preferably, the length of the push rod 33 is 600 mm, and the connecting portion 332 is provided at 60 mm from the rotating portion 331 to the holding portion 333 direction of the push rod 33.

[0098] Further, the umbrella rope cutter 32 includes: a cutting blade 322, a first fixing plate 321, and a cover plate 323. The first fixing plate 321 is provided with a cutting notch 3211; the cutting blade 322 is detachably connected to the first fixing plate 321, and the cutting edge of the cutting blade 322 is exposed in the cutting notch 3211; the cover plate 323 is detachably connected to the first fixing plate 321, and the cutting blade 322 is clamped between the first fixing plate 321 and the cover plate 323.

[0099] Specifically, the cutting blade 322 is fixed on the first fixing plate 321 by a detachable connection method and is clamped by the cover plate 323. This design ensures the stability of the cutting blade 322 during the cutting process, reduces the problems of incomplete cutting or deviation caused by blade loosening, and improves the cutting quality. Secondly, the setting of the cutting notch 3211 enables the cutting edge of the cutting blade 322 to accurately contact the parachute cord, optimizing the cutting angle and cutting path, and further improving the cutting efficiency and quality. In addition, this structural design facilitates the replacement and maintenance of the cutting blade 322. When the cutting blade 322 is worn or damaged, the operator can quickly remove the cover plate 323 and replace it with a new cutting blade 322, reducing the downtime and improving the production efficiency. At the same time, the adoption of the detachable connection method also makes the installation and adjustment of the cutting blade 322 more convenient, without the need for complex tools or cumbersome operation steps, reducing the maintenance cost and operation difficulty. Finally, the overall design of the parachute cord cutter 32 also has good compatibility and adaptability. By adjusting the size, shape, and material of the cutting blade 322, it can easily meet the cutting requirements of parachute cords of different specifications and materials, enhancing the versatility and flexibility of the device, and further improving the application value and market competitiveness of the parachute cord cutting device 30 in the parachute manufacturing field.

[0100] Furthermore, the cover plate 323 is provided with at least two positioning posts 3231. The cutting blade 322 is provided with first positioning holes 3221 corresponding to the positions of the positioning posts 3231, and the first fixing plate 321 is provided with second positioning holes 3212 corresponding to the positions of the positioning posts 3231. The positioning posts 3231 pass through the first positioning holes 3221 and the second positioning holes 3212.

[0101] Specifically, when assembling the parachute cord cutter 32, the operator places the cutting blade 322 on the first fixing plate 321, aligns the first positioning holes 3221 of the cutting blade 322 with the positioning posts 3231 on the cover plate 323, and inserts the positioning posts 3231 into the first positioning holes 3221 to initially fix the position of the cutting blade 322. Subsequently, the cover plate 323 is placed on the first fixing plate 321, and the positioning posts 3231 of the cover plate 323 are aligned with and inserted into the second positioning holes 3212 of the first fixing plate 321. At this time, the first fixing plate 321, the cover plate 323, and the cutting blade 322 are initially positioned through the cooperation of the positioning posts 3231, the first positioning holes 3221, and the second positioning holes 3212. Then, the cover plate 323 is fixed on the first fixing plate 321 by a detachable connection method to further press the cutting blade 322 to ensure its firm installation. Preferably, the cover plate 323 and the first fixing plate 321 are connected by bolts.

[0102] Furthermore, the cutting notch 3211 is provided on the lower side of the first fixing plate 321, and the cutting station is provided on the lower side of the initial station.

[0103] Specifically, in the initial state, the umbrella cord cutter 32 is located at the initial working station. The cutting edge of the cutting blade 322 is at the cutting notch 3211. The umbrella cord cutter 32 and the mounting base 31 are relatively stationary, waiting for a cutting instruction. The umbrella cord passes horizontally through the cutting station and is located below the cutting notch 3211. Then, the operator holds the holding part 333 of the pressure lever 33 and applies downward pressure. The pressure lever 33 starts to rotate around its rotating part 331, driving the umbrella cord cutter 32 to move downward along the vertical direction through the connecting rod 34. As the pressure lever 33 rotates, the umbrella cord cutter 32 gradually approaches the cutting station. The umbrella cord enters the cutting notch 3211 and starts to contact the cutting edge of the cutting blade 322. As the umbrella cord cutter 32 continues to move downward, the cutting blade 322 exerts an increasingly large force on the umbrella cord, and finally completes the cutting action. During this process, the design of the cutting notch 3211 ensures the precise contact between the cutting blade 322 and the umbrella cord, reducing the displacement or deformation of the umbrella cord.

[0104] Furthermore, the angle between the cutting edge of the cutting blade 322 and the horizontal direction in the cutting notch 3211 is 60°, and the length of the cutting edge of the cutting blade 322 is 18 mm.

[0105] It should be explained that when the cutting blade 322 of the umbrella cord cutter 32 is inclined, part of the cutting force is provided by the side wall of the cutting blade 322. Therefore, under the condition of achieving the same cutting force, the required downward pressure becomes smaller. Based on this principle, in order to further reduce the force required for the cutting action, in this embodiment, the cutting blade 322 is arranged to be inclined at 60°.

[0106] Meanwhile, the overall size of the cutting blade 322 is mainly determined according to the diameter of the umbrella cord to be cut. The diameter of the umbrella cord in the market is about between 2 mm and 5 mm. On the premise of meeting the cutting requirements, the size should be reduced as much as possible to save materials. When the cutting blade 322 is inclined, the size of the projection of the cutting blade 322 in the horizontal direction is the maximum cutting width. For the umbrella cord with a diameter of 2 - 5 mm, the maximum cutting width should be at least greater than 5 mm. On this basis, 2 mm of allowance is left on each side in this embodiment, and finally the cutting width across the cutting blade 322 in the horizontal direction is determined to be 9 mm. Therefore, when the cutting blade 322 is arranged to be inclined at an angle of 60°, the length of the cutting blade 322 is 18 mm.

[0107] Furthermore, the cutting blade 322 is made of T8 high carbon steel, and the edge angle of the cutting edge of the cutting blade 322 is in the range of 25° - 35°. Preferably, the edge angle of the cutting edge of the cutting blade 322 is 30°.

[0108] It should be noted that considering that the temperature and humidity in the parachute production workshop have been controlled to a certain extent, the cutting blade 322 has low requirements for rust prevention ability. The main focus is on two performance indicators: sharpness and durability. Considering the above factors, high-hardness T8 high-carbon steel is selected as the material for the cutting blade 322 to achieve the best sharpness and durability. Further, regarding the selection of the edge angle of the cutting blade 322, a small edge angle (15°-25°) results in a thinner edge and less cutting resistance. Therefore, it can reduce the extrusion deformation when cutting flexible materials. However, when the hardness of the blade material is high, chipping is likely to occur due to impact, and when the hardness is low, the blade is prone to curling and has poor durability, requiring frequent grinding. A medium edge angle (25°-35°) balances sharpness and durability, with an increase in cutting resistance compared to a small edge angle. A large edge angle (35°-45°) has a thicker edge, enabling it to withstand high impact forces and the friction of hard materials, with extremely high durability, but the cutting resistance increases significantly, resulting in low cutting efficiency. Considering all factors, a medium edge angle of 30° is selected in this embodiment to balance cutting efficiency and durability.

[0109] Please refer to Figures 16 to 21 , in some embodiments, the umbrella rope clamping device 40 includes: a moving mechanism 41, including a moving end that moves linearly; a clamping mechanism 42, including a mounting seat 31 connected to the moving end, and a first chuck 424 and a second chuck 425 movably arranged on the mounting seat 31. A positioning gap for clamping the umbrella rope is formed between the first chuck 424 and the second chuck 425; a driving mechanism 43, drivingly connected to the first chuck 424 and / or the second chuck 425, driving the first chuck 424 and the second chuck 425 to move relatively closer or relatively farther away to change the size of the positioning gap; wherein, the parts of the first chuck 424 and the second chuck 425 for clamping the umbrella rope are made of rubber material. Preferably, the parts of the first chuck 424 and the second chuck 425 for clamping the umbrella rope are made of neoprene material.

[0110] In some embodiments, initially, the moving end of the moving mechanism 41 is at the starting position, and the positioning gap of the clamping mechanism 42 is the largest, facilitating the insertion of the umbrella rope. After the driving mechanism 43 is activated, the first chuck 424 and the second chuck 425 move relatively closer, the positioning gap shrinks, and the umbrella rope is stably clamped. At the same time, the moving mechanism 41 drives the moving end to move linearly, and the clamping mechanism 42 transfers the umbrella rope from the current position to the target position accordingly. After arriving, the driving mechanism 43 drives the first chuck 424 and the second chuck 425 to move in the reverse direction, the positioning gap increases, and the umbrella rope is released. The entire process realizes the automatic clamping and precise movement of the umbrella rope, reduces manual intervention, and improves production efficiency and quality.

[0111] It should be explained that, due to the weaving method, Vectran braided rope, ultra-high molecular weight polyethylene braided rope, and aramid braided rope are all hollow structures. The characteristics of this braided structure make it only able to withstand tension in the radial direction, but cannot withstand forces in other directions. The impact of this is reflected in the following: when trying to clamp through the side of the rope, the umbrella rope is subjected to positive pressure perpendicular to the side wall, which in turn produces a large deformation. As the positive pressure increases, the umbrella rope cannot maintain a circular state due to the hollow interior, and gradually tends to be flat, and its cross-section changes from circular to flat. Therefore, the clamping mechanism 42 should be able to adapt to the deformation caused by the pressure on the umbrella rope, and can work reliably in this case, and always maintain a stable clamping, that is, the end of the clamp in the clamping mechanism 42 that is in direct contact with the umbrella rope should have a certain elasticity, increasing the contact area with the umbrella rope while preventing damage to the umbrella rope. In this embodiment, the first clamp 424 and the second clamp 425 are made of rubber material for clamping the parachute rope. Rubber has good elasticity, a high friction coefficient and is not easy to damage the surface of the parachute rope. It can ensure that the parachute rope will neither slip nor be clamped during the clamping process, thereby effectively protecting the quality of the parachute rope.

[0112] In some embodiments, the first clamp 424 includes a first connecting member 4241 and a first rubber member 4242, and the first rubber member 4242 is sleeved on the outside of one end of the first connecting member 4241; the second clamp 425 includes a second connecting member and a second rubber member, and the second rubber member is sleeved on the outside of one end of the second connecting member; a positioning gap is formed between the first rubber member 4242 and the second rubber member.

[0113] Furthermore, the mounting seat 31 includes a first guide plate 421 and a second guide plate 422, and the first guide plate 421 is movably connected to the second guide plate 422; one of the first guide plate 421 and the second guide plate 422 is relatively fixed to the movable end, and the other is transmission-connected to the driving mechanism 43; the first guide plate 421 is provided with a first guide groove 4211, and the second guide plate 422 is provided with a second guide groove 4221 and a third guide groove 4222, and the central axis of the second guide groove 4221 and the third guide groove 4222 intersect, the first clamp 424 is slidably provided in the first guide groove 4211 and the second guide groove 4221, and the second clamp 425 is slidably provided in the first guide groove 4211 and the third guide groove 4222.

[0114] It can be understood that when the driving mechanism 43 is working, the first guide plate 421 or the second guide plate 422 connected to the driving mechanism 43 starts to move, and the relative movement of the first guide plate 421 and the second guide plate 422 drives the first clamp 424 and the second clamp 425 to slide in the second guide groove 4221 and the third guide groove 4222 respectively. With the relative movement of the first guide plate 421 and the second guide plate 422, the first clamp 424 slides along the first guide groove 4211 and the second guide groove 4221, and the second clamp 425 slides along the first guide groove 4211 and the third guide groove 4222. Since the central axes of the second guide groove 4221 and the third guide groove 4222 intersect, the first clamp 424 and the second clamp 425 will gradually move closer or farther away from each other during the sliding process, thereby changing the size of the positioning gap and achieving the clamping or loosening action of the parachute rope. In this process, the first guide groove 4211, the second guide groove 4221, and the third guide groove 4222 always guide and limit the movement of the first chuck 424 and the second chuck 425, ensuring that the first chuck 424 and the second chuck 425 move along a predetermined trajectory, making the clamping action more stable and accurate.

[0115] Furthermore, the second guide groove 4221 is axially symmetrical with the third guide groove 4222, and the central axis of the first guide groove 4211 is perpendicular to the normal plane where the symmetry axis of the second guide groove 4221 and the third guide groove 4222 is located. The symmetry of the second guide groove 4221 and the third guide groove 4222 ensures that the first chuck 424 and the second chuck 425 are subjected to uniform force during movement, and the movement trajectories are symmetrical, thereby ensuring that the change of the positioning gap is uniform and consistent.

[0116] In some embodiments, the second guide plate is made of 45 steel. To make the structure compact and reduce friction during movement, the inclination angles of the second guide groove and the third guide groove are -20° and 20° respectively.

[0117] Furthermore, the mounting base 31 also includes a second fixing plate 423, the second fixing plate 423 is fixedly connected to the movable end, the second guide plate 422 is fixedly connected to the second fixing plate 423, the first guide plate 421 is arranged between the second fixing plate 423 and the second guide plate 422, and the first guide plate 421 is transmission-connected to the driving mechanism 43.

[0118] Specifically, when the driving mechanism 43 is activated, the power transmission component connected to the first guiding plate 421 drives the first guiding plate 421 to move in a horizontal direction perpendicular to the central axis of the first guiding groove 4211. Since the second guiding plate 422 is fixed, the movement of the first guiding plate 421 causes the first chuck 424 and the second chuck 425 disposed in the first guiding groove 4211, the second guiding groove 4221, and the first guiding groove 4211, the third guiding groove 4222 to slide in the corresponding guiding grooves respectively. As the first guiding plate 421 moves, the chucks gradually approach or move away from each other, thereby realizing the clamping or loosening action on the umbrella ropes.

[0119] Furthermore, the first guiding plate 421 is movably arranged in a horizontal direction perpendicular to the central axis of the first guiding groove 4211.

[0120] Furthermore, the driving mechanism 43 includes a first driving motor 431, a second driving motor, a first lead screw 432, and a second lead screw. The first driving motor 431 and the second driving motor are respectively mounted on the second fixing plate 423. The first lead screw 432 is connected to the output end of the first driving motor 431, and the second lead screw is connected to the output end of the second driving motor. The first guiding plate 421 is provided with a first threaded hole 4212 and a second threaded hole 4213 in a horizontal direction perpendicular to the central axis of the first guiding groove 4211. The first lead screw 432 is threadedly connected to the first threaded hole 4212, and the second lead screw is threadedly connected to the second threaded hole 4213. Preferably, the first threaded hole 4212 and the second threaded hole 4213 are respectively located on both sides of the first guiding groove 4211.

[0121] Specifically, when it is necessary to adjust the positioning gap between the first chuck 424 and the second chuck 425 to clamp or release the umbrella ropes, the first driving motor 431 and the second driving motor are simultaneously activated to drive the first lead screw 432 and the second lead screw to rotate respectively. Due to the threaded connection relationship between the first lead screw 432, the second lead screw and the first threaded hole 4212 and the second threaded hole 4213 on the first guiding plate 421, the rotational motion is converted into a linear motion, causing the first guiding plate 421 to move in a horizontal direction perpendicular to the central axis of the first guiding groove 4211. As the first guiding plate 421 moves, the first chuck 424 and the second chuck 425 slide in the first guiding groove 4211, the second guiding groove 4221, and the first guiding groove 4211, the third guiding groove 4222 respectively, thereby gradually approaching or moving away from each other to realize a uniform change in the positioning gap.

[0122] Further, the groove width of the first guiding groove 4211 is greater than the groove widths of the second guiding groove 4221 and the third guiding groove 4222. The first connecting member 4241 includes a first diameter portion 42411, a second diameter portion 42412, and a first connecting portion 42413. The first diameter portion 42411 is located in the first guiding groove 4211, the second diameter portion 42412 is located in the second guiding groove 4221, and the diameter of the first diameter portion 42411 is greater than the groove width of the second guiding groove 4221. The first connecting portion 42413 is located on the side of the second guiding plate 422 away from the first guiding plate 421. The first rubber member 4242 is clamped to the first connecting portion 42413, and the minimum outer diameter of the first rubber member 4242 is greater than the groove width of the second guiding groove 4221.

[0123] Further, the moving mechanism 41 includes a linear motor.

[0124] In some embodiments, the moving mechanism 41 further includes a driver and a feedback device. The driver is of a pulse control type and is used to drive the movement of the moving end of the linear motor. The feedback device is an incremental magnetic encoder with a resolution of 1 micron and is used to detect the position of the moving end.

[0125] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be regarded as equivalent replacement methods and are all included in the protection scope of the present invention.
