[0014] One beneficial effect of the present invention is that: the present invention provides a fixed-length cutting system for electromagnetic shielding cables, and the beneficial effects of the system are specifically embodied in the following aspects: Improve cutting accuracy and efficiency: Through the close cooperation between the sensor and the cutting component, the cutting length of the cable can be accurately controlled to ensure that each cut meets the predetermined size requirements. The automated cutting process reduces manual intervention, improves cutting efficiency, and reduces errors caused by improper manual operation.

[0015] Enhance system adaptability and flexibility: The steel frame and rib plate in the cable winding and unwinding assembly are arranged in an A-shaped structure, and an adjustable first height limit device and a second height limit device are respectively arranged at the upper and lower ends of the steel frame, which enables the system to adapt to cables of different diameters and lengths, thereby enhancing the adaptability of the system.

[0016] Ensure stability and safety during cutting: The design of the fixed frame and mounting plate provides a stable support for the cutting assembly, ensuring stability during the cutting process. The setting of the first and second height limit devices, as well as the adjustability of the telescopic shaft, help to maintain the stable position of the cable during the cutting process, preventing cutting errors or safety accidents caused by cable shaking or deviation. The use of automated systems and sensors reduces the risk of manual operation and improves workplace safety.

[0017] Optimize cable transportation and cutting processes: The coordinated work of the driving transport component and the fixed transport component enables the smooth transportation of the cable in the system and reduces the friction and resistance during transportation. The close cooperation between the cutting component and the driving transport component enables the cable to be accurately positioned and fixed before cutting, thereby improving the accuracy and efficiency of cutting.

[0018] The present invention also provides a process for a fixed-length cutting system for electromagnetic shielding cables, the process comprising the following steps: Step 1: Ensure that the cable cutting structure, cable winding and unwinding components, driving and transporting components, and fixed transporting components are properly installed and in good working condition. Start the system power supply and check whether the electrical equipment such as sensors, driving motors, and conveying motors are normal. Set the corresponding parameters in the system according to the cable length that needs to be cut. Step 2: Place the cable on the pay-off drum of the cable winding and pay-off assembly, and stably support it through the support shaft and the steel frame structure. The first height limiter and the second height limiter adjust the height through the telescopic shaft and the fixing hole to ensure that the cable maintains a stable tension during the pay-off process to avoid excessive relaxation or tension. Start the conveying motor to drive the pay-off drum to rotate and pay out the cable at the set speed; Step 3: After the cable is released from the pay-off drum, it enters the fixed transport assembly. The horizontal sliding wheel and the longitudinal sliding wheel cooperate with the mounting block to ensure that the cable remains in a stable straight state before cutting; Step 4: After the cable passes through the fixed transport component, it enters the drive transport component. The drive motor starts and drives the transport pulley to rotate through the drive shaft to transport the cable. The outlet adjustment block and the outlet support plate cooperate with the outlet spring to ensure that the cable remains stable during transportation to avoid deviation or distortion. After the sensor detects that the cable has reached the predetermined position, it sends a signal to the system to prepare for cutting; Step 5: After receiving the signal from the sensor, the cutting assembly starts working, the connecting column is extended and retracted to adjust the position of the cutting knife to ensure cutting accuracy, the cable enters from one end of the feed bobbin, and the cutting knife quickly and accurately cuts the cable to complete a fixed-length cutting; Step 6: The cut cable sections are sent out through the discharge bobbin for collection or further processing. After completing one cut, the system automatically resets and prepares for the next cut. The above steps are repeated until all cables are cut to the required length.

[0019] Another beneficial effect of the present invention is: Improve production efficiency and quality: Precise control of cutting length: By setting the corresponding cable cutting parameters in the system in step one and the precise operation of the cutting components in step five, it can be ensured that the cable length each time is cut meets the predetermined requirements, thereby improving the qualified rate and overall quality of the product.

[0020] Automated operation reduces manual intervention: During the entire process, most operations, from cable laying, transportation to cutting, are automated, greatly reducing manual intervention. This not only improves production efficiency, but also reduces errors caused by human factors.

[0021] Enhanced system stability and reliability: Equipment inspection ensures good working condition: The inspection of each component and electrical equipment in step 1 can ensure that the entire system is in optimal condition during operation, reducing interruptions and maintenance costs caused by equipment failure.

[0022] Stable support and tension control: In step 2, the design of the support shaft, steel frame structure and height limit device ensures stable support and tension control of the cable during the laying process, avoiding cable damage or inaccurate cutting due to improper tension.

[0023] Improve operational convenience and safety: Convenient operation process: The entire process is reasonably designed with clear steps. Operators only need to perform simple operations according to the process, which greatly improves the convenience of operation.

[0024] Multiple safety guarantees: The system is equipped with safety devices such as sensors and cable adjustment blocks, which can provide real-time monitoring and protection during cable transportation and cutting, ensuring the safety of operators.

[0025] When the present invention is working, ensure that all components such as the cable cutting structure, cable winding and unwinding assembly, drive transport assembly, fixed transport assembly, etc. are correctly installed and in good working condition, start the system power supply, check whether electrical equipment such as sensors, drive motors, and conveying motors are operating normally, without abnormal sounds or overheating, and set corresponding cutting parameters in the system according to the length requirements of the cable to be cut, such as cutting length, unwinding speed, etc.

[0026] Place the cable on the pay-off drum of the cable winding and unwinding assembly to ensure that the cable end is firmly fixed. The cable is stably supported by the support shaft and the steel frame structure to prevent the cable from shaking during the pay-off process. Use the first height limiter and the second height limiter to adjust the height through the telescopic shaft and the fixing hole to ensure that the cable maintains a stable tension during the pay-off process. Start the conveying motor to drive the pay-off drum to rotate and pay out the cable smoothly at the set speed.

[0027] After the cable is released from the pay-off drum, it enters the fixed transport component. The horizontal sliding wheel and the longitudinal sliding wheel cooperate with the mounting block to ensure that the cable remains in a stable straight state during transportation to avoid bending or twisting. After passing through the fixed transport component, the cable enters the driven transport component. The drive motor starts and drives the transport pulley to rotate through the drive shaft to achieve smooth transportation of the cable. The line adjustment block and the line support plate cooperate with the line spring to further ensure the stability and accuracy of the cable during transportation. The sensor detects the position of the cable in real time. When the cable reaches the predetermined position, it sends a signal to the system to prepare for cutting.

[0028] After receiving the signal from the sensor, the cutting assembly starts working. The connecting column is extended and retracted to adjust the position of the cutting knife to ensure cutting accuracy. The cable enters from one end of the feed bobbin, and the cutting knife quickly and accurately cuts the cable. After one cut, the system automatically resets and prepares for the next cut. Repeat the above steps until all cables are cut to the required length. BRIEF DESCRIPTION OF THE DRAWINGS

10. The process of a cut-to-length system for electromagnetic shielding cables according to claim 1, characterized in that: The process comprises the following steps: Step 1: Ensure that the cable cutting structure (1), the cable winding and unwinding assembly (5), the driving and transporting assembly (6), the fixed transporting assembly (7), etc. are properly installed and in good working condition, start the system power supply, check whether the electrical equipment such as the sensor, the driving motor (605), the conveying motor (505) are normal, and set the corresponding parameters in the system according to the cable length to be cut; Step 2: Place the cable on the pay-off drum of the cable winding and unwinding assembly (5), and stably support it through the support shaft (11) and the steel frame (503) structure. The first height limiting device (8) and the second height limiting device (9) adjust the height through the telescopic shaft (10) and the fixing hole (506) to ensure that the cable maintains a stable tension during the pay-off process to avoid excessive relaxation or tension. Start the conveying motor (505) to drive the pay-off drum to rotate and pay out the cable at a set speed. Step 3: After the cable is released from the pay-off drum, it enters the fixed transport assembly (7), and the transverse sliding wheel (703) and the longitudinal sliding wheel (704) cooperate with the mounting block (702) to ensure that the cable remains in a stable straight state before cutting; Step 4: After the cable passes through the fixed transport component (7), it enters the drive transport component (6), the drive motor (605) is started, and the transport pulley (607) is driven to rotate through the drive shaft (608), thereby transporting the cable. The outlet adjustment block (602) and the outlet support plate (603) cooperate with the outlet spring (604) to ensure that the cable remains stable during transportation and avoids deviation or twisting. After the sensor detects that the cable has reached the predetermined position, it sends a signal to the system to prepare for cutting; Step 5: After receiving the signal from the sensor, the cutting assembly (4) starts to work, the connecting column (403) is extended and retracted to adjust the position of the cutting knife (404) to ensure cutting accuracy, the cable enters from one end of the feed bobbin (405), and the cutting knife (404) quickly and accurately cuts the cable, completing a fixed-length cutting; Step 6: The cut cable segments are sent out through the discharge bobbin (406) for collection or further processing. After completing one cut, the system automatically resets and prepares for the next cut. The above steps are repeated until all cables are cut to the required length.
