[0037] Please see Figure 1 and Figure 2 This utility model provides a paracord cutting device, including: a mounting base 10; a paracord cutter 20, slidably connected to the mounting base 10 in a vertical direction; and a pressure rod 30, rotatably connected to the mounting base 10, and movably connected to the paracord cutter 20. The mounting base 10 is provided with an initial working position and a cutting position, and the pressure rod 30 drives the paracord cutter 20 to move between the initial working position and the cutting position. In this embodiment, by movably connecting the pressure rod 30 to the paracord cutter 20, the rotation of the pressure rod 30 is converted into the sliding of the paracord cutter 20 in a vertical direction. The operator only needs to apply a relatively small force to the pressure rod 30, and through the lever principle and mechanical transmission, the paracord cutter 20 can be driven to complete the cutting of the paracord, reducing the operator's physical exertion, lowering labor intensity, and improving work comfort and sustainability.

[0038] Specifically, in the initial state, the paracord cutter 20 is located in the initial position of the mounting base 10, and the pressure rod 30 is in its natural position. At this time, the paracord cutter 20 and the mounting base 10 are relatively stationary, awaiting the placement and cutting instructions for the paracord. When cutting is initiated, the operator applies downward pressure to the pressure rod 30, which begins to rotate around its rotational connection point with the mounting base 10. During rotation, the pressure rod 30 drives the paracord cutter 20 to move vertically downward, gradually approaching the cutting position. Simultaneously, the cutting blade 22 of the paracord cutter 20 begins to contact and compress the paracord. As the pressure rod 30 continues to rotate, the paracord cutter 20 reaches the cutting position, and the cutting blade 22 applies sufficient force to the paracord to complete the cutting action. After cutting is completed, the operator lifts the pressure rod 30 back to the initial position, and the paracord cutter 20 also returns to its initial position. The paracord cutting device returns to its initial state, ready for the next cut.

[0039] Furthermore, the pressure bar 30 includes: a pressure bar 30 body, and a rotating part 31, a connecting part 32, and a holding part 33 disposed on the pressure bar 30 body. The rotating part 31 and the holding part 33 are respectively disposed at both ends of the pressure bar 30 body, and the connecting part 32 is disposed between the rotating part 31 and the holding part 33. The rotating part 31 is rotatably connected to the mounting base 10, and the connecting part 32 is movably connected to the paracord cutter 20. Optionally, the holding part 33 is provided with a handle for easy gripping by the operator, and the surface of the handle can be made of rubber or silicone.

[0040] Furthermore, the paracord cutting device also includes a connecting rod 40, one end of which is rotatably connected to the connecting part 32, and the other end is rotatably connected to the paracord cutter 20. It is understood that during the rotation of the pressure rod 30, the connecting rod 40 can uniformly convert the rotational motion into the linear motion of the paracord cutter 20, reducing vibration and jamming during the movement, and improving the stability of the cutting action and the consistency of the paracord cutting length.

[0041] Specifically, the length of the pressure rod 30 is in the range of 600mm-900mm, and the connecting part 32 is located at one-tenth of the length of the pressure rod 30 from the rotating part 31 to the holding part 33; the rotation angle of the pressure rod 30 driving the paracord cutter 20 from the initial position to the cutting position is 30°. Preferably, the length of the pressure rod 30 is 600mm, and the connecting part 32 is located at 60mm from the rotating part 31 to the holding part 33.

[0042] Please see Figures 3 to 8 Furthermore, the paracord cutter 20 includes: a cutting blade 22, a fixing plate 21, and a cover plate 23. The fixing plate 21 is provided with a cutting notch 211. The cutting blade 22 is detachably connected to the fixing plate 21, and the cutting edge of the cutting blade 22 is exposed in the cutting notch 211. The cover plate 23 is detachably connected to the fixing plate 21, and the cutting blade 22 is clamped between the fixing plate 21 and the cover plate 23.

[0043] Specifically, the cutting blade 22 is detachably fixed to the fixing plate 21 and held by the cover plate 23. This design ensures the stability of the cutting blade 22 during the cutting process, reducing incomplete or deviated cutting caused by blade loosening and improving cutting quality. Secondly, the cutting notch 211 allows the cutting edge of the cutting blade 22 to accurately contact the paracord, optimizing the cutting angle and path, further improving cutting efficiency and quality. Furthermore, this structural design facilitates the replacement and maintenance of the cutting blade 22. When the cutting blade 22 is worn or damaged, the operator can quickly remove the cover plate 23 to replace it with a new blade, reducing downtime and improving production efficiency. Simultaneously, the detachable connection method makes the installation and adjustment of the cutting blade 22 more convenient, requiring no complex tools or cumbersome operating procedures, reducing maintenance costs and operational difficulty. Finally, the overall design of the paracord cutter 20 also has good compatibility and adaptability. By adjusting the size, shape, and material of the cutting blade 22, the device can easily meet the needs of cutting paracords of different specifications and materials, enhancing its versatility and flexibility, and further improving the application value and market competitiveness of the paracord cutting device in the parachute manufacturing field.

[0044] Furthermore, the cover plate 23 is provided with at least two positioning posts 231, the cutting blade 22 is provided with a first positioning hole 221 corresponding to the position of the positioning post 231, and the fixing plate 21 is provided with a second positioning hole 212 corresponding to the position of the positioning post 231. The positioning post 231 passes through the first positioning hole 221 and the second positioning hole 212.

[0045] Specifically, during the assembly of the paracord cutter 20, the operator places the cutting blade 22 on the fixing plate 21, aligning the first positioning hole 221 of the cutting blade 22 with the positioning post 231 on the cover plate 23. The positioning post 231 is inserted into the first positioning hole 221, initially fixing the position of the cutting blade 22. Then, the cover plate 23 is placed on the fixing plate 21, aligning and inserting the positioning post 231 of the cover plate 23 into the second positioning hole 212 of the fixing plate 21. At this point, the fixing plate 21, the cover plate 23, and the cutting blade 22 achieve initial positioning through the cooperation of the positioning post 231, the first positioning hole 221, and the second positioning hole 212. Next, the cover plate 23 is fixed to the fixing plate 21 via a detachable connection, further pressing the cutting blade 22 to ensure its secure installation. Preferably, the cover plate 23 and the fixing plate 21 are connected by bolts.

[0046] Furthermore, the cutting notch 211 is located on the lower side of the fixed plate 21, and the cutting station is located on the lower side of the initial station.

[0047] Specifically, in the initial state, the paracord cutter 20 is located in the initial position, the cutting edge of the cutting blade 22 is in the cutting notch 211, and the paracord cutter 20 is relatively stationary with respect to the mounting base 10, awaiting the cutting command. The paracord passes horizontally through the cutting position and is located below the cutting notch 211. Next, the operator holds the grip part 33 of the pressure lever 30 and applies downward pressure. The pressure lever 30 begins to rotate around its rotating part 31, driving the paracord cutter 20 to move downward vertically through the connecting rod 40. As the pressure lever 30 rotates, the paracord cutter 20 gradually approaches the cutting position, the paracord enters the cutting notch 211 and begins to contact the cutting edge of the cutting blade 22. As the paracord cutter 20 continues to move downward, the cutting blade 22 applies increasingly greater force to the paracord, ultimately completing the cutting action. During this process, the design of the cutting notch 211 ensures precise contact between the cutting blade 22 and the paracord, reducing displacement or deformation of the paracord.

[0048] Furthermore, the cutting edge of the cutting blade 22 forms an angle of 60° with the horizontal direction in the cutting notch 211, and the cutting edge length of the cutting blade 22 is 18mm.

[0049] It should be explained that when the cutting blade 22 of the paracord cutter 20 is placed at an angle, part of the cutting force is provided by the side wall of the cutting blade 22. Therefore, the required downward pressure is reduced to achieve the same cutting force. Based on this principle, in order to further reduce the force required for the cutting action, the cutting blade 22 is arranged at an angle of 60° in this embodiment.

[0050] Meanwhile, the overall size of the cutting blade 22 is mainly determined by the diameter of the paracord to be cut. The diameter of paracord on the market is approximately 2mm-5mm. While meeting the cutting requirements, the size should be minimized as much as possible to save materials. When the cutting blade 22 is arranged at an angle, the projection of the cutting blade 22 in the horizontal direction is the maximum cutting width. For cutting paracord with a diameter of 2-5mm, the maximum cutting width should be at least greater than 5mm. In this embodiment, a 2mm allowance is left on each side, ultimately determining the horizontal cutting width of the cutting blade 22 to be 9mm. Therefore, when the cutting blade 22 is arranged at a 60° angle, the length of the cutting blade 22 is 18mm.

[0051] Furthermore, the cutting blade 22 is made of T8 high-carbon steel, and the cutting angle of the cutting blade 22 is in the range of 25°-35°. Preferably, the cutting angle of the cutting blade 22 is 30°.

[0052] It should be explained that, considering the temperature and humidity are already controlled in the parachute production workshop, the rust resistance requirement for the cutting blade 22 is not high. The main focus is on sharpness and durability. Taking all these factors into account, T8 high-carbon steel with higher hardness was selected as the material for the cutting blade 22 to achieve optimal sharpness and durability. Furthermore, regarding the selection of the cutting edge angle of the cutting blade 22, a small cutting edge angle (15°-25°) results in a thinner cutting edge and less cutting resistance, thus reducing extrusion deformation when cutting flexible materials. However, if the blade material has high hardness, it is prone to chipping due to impact; if the hardness is low, it is prone to chipping, resulting in poor durability and requiring high-frequency sharpening. A medium cutting edge angle (25°-35°) balances sharpness and durability, but the cutting resistance is slightly increased compared to a small cutting edge angle. A large cutting edge angle (35°-45°) has a thicker cutting edge, allowing it to withstand high impact forces and friction from hard materials, resulting in extremely high durability, but the cutting resistance is significantly increased, leading to low cutting efficiency. Taking all factors into consideration, this embodiment selects a 30° center cutting angle to balance cutting efficiency and durability.

[0053] This utility model provides a paracord processing device, including a reel and a paracord cutting device. The reel is loaded with a paracord coil, and the paracord is pulled out from the paracord coil and passes through the cutting station of the paracord cutting device.

[0054] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be regarded as equivalent substitutions and shall be included within the protection scope of the present utility model.
