Description

Technical Field

[0001] The invention belongs to the technical field of cable cutting, and in particular relates to an equal-length cutting machine for processing low-altitude economic cables. Background Art

[0002] In recent years, with the rapid development of drone technology, urban air traffic (UAM), logistics distribution, agricultural monitoring and other fields, the low-altitude economy has gradually become a new economic growth point. The low-altitude economy covers various activities from the ground to an altitude of about 1,000 feet (about 305 meters), which have an increasing demand for power transmission and communication. Especially in the fields of urban air traffic and drone logistics, the quality and reliability of cables, as part of the critical infrastructure, directly affect the operating efficiency and safety of the system. Therefore, higher requirements are placed on cable processing equipment, including higher precision, stronger adaptability and higher production efficiency.

[0003] Traditional cable processing equipment usually relies on manual operation or semi-automatic mechanical devices. These methods make it difficult to ensure the consistency of each cutting length, resulting in unstable quality of the finished product. In addition, manual or semi-automatic equipment is inefficient when processing large quantities of cables, and requires frequent parameter adjustments, which consumes a lot of time and manpower. Cables of different specifications and types require different clamping and cutting forces. Existing equipment often lacks the ability to adjust flexibly, which can easily damage the cables and affect their electrical performance and service life.

[0004] Pneumatic control technology has been widely used in the field of industrial automation due to its high efficiency, precision and easy maintenance, but its application in the field of cable processing still faces some challenges. Although existing cable processing equipment has tried to introduce pneumatic control systems to improve processing accuracy and efficiency, there are generally problems such as difficulty in coordinated control of multiple components and complex pressure regulation. In order to adapt to cables of different thicknesses and materials, the air pressure must be flexibly adjusted, which places high demands on the sensitivity and stability of the pressure regulating system. In addition, most of the existing equipment has a single function and can only complete basic cutting tasks. It is impossible to take into account multiple links such as cable feeding, length setting, cutting and unloading at the same time, which limits its scope of application and efficiency in actual production.

[0005] Therefore, in view of the above situation, it is urgent to develop an equal-length cutting machine for low-altitude economic cable processing to overcome the shortcomings in current practical applications. Summary of the invention

The pneumatic control mechanism A is used to adjust the clamping force and adaptation size of all clamping and conveying assemblies to adapt to cables 1 of different specifications.

[0041] When the cable 1 reaches the predetermined length, the touch switch on the positioning block 18 is triggered, the power wheel 40 stops rotating, the air pump B29 starts, pressurizes the inner cavity of the air distribution plate B23, and the cutting cylinder 25 drives the cutting knife 37 to quickly and accurately cut the cable 1. The cutting force is adjusted by the pneumatic control mechanism B to ensure that the cable 1 or the device will not be damaged during the cutting process.

[0042] After the cutting is completed, the positioning telescopic cylinder 20 is extended, and at the same time, the cable output telescopic cylinder 12 close to the cutting conveying cylinder 22 is also extended, so that the cable output support 13 is tilted, and the cut cable 1 is assisted to be removed from the cable output support plate 17, completing the entire processing flow.
