Description

Technical Field

[0001] This invention relates to the field of cable processing equipment technology, and more specifically, to a mineral cable sheathing stripping device and stripping method. Background Technology

[0002] In the manufacturing and rework of mineral cables, it is often necessary to peel off the outer metal corrugated layer, wrapping layer, or sheath layer. Currently, the industry mainly relies on manual labor for this operation: operators use cutting tools such as angle grinders to break open the cable wrapping layer fixed between the pay-off machine and the take-up machine, and then use tools such as pry bars to peel off the wrapping layer. This traditional manual peeling method has significant drawbacks: First, the operation process poses a great threat to the personal safety of workers, with the risk of injury from cutting tools, and the large amount of metal dust generated during the cutting process can be harmful to human health; second, manual peeling is extremely inefficient, severely restricting production speed; third, relying on manual control of the cutting depth makes it very easy to damage the conductor inside the cable due to improper depth control, resulting in the scrapping of the entire cable. Summary of the Invention

[0003] The purpose of this invention is to provide a mineral cable sheathing stripping device and method, which addresses the shortcomings of existing technologies and solves the problems mentioned in the background.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A mineral cable sheathing stripping device, comprising: a frame; The first mold, mounted on the frame, is used to support the cable; The second mold is positioned above the first mold and cooperates with the first mold to fix the cable; The first lifting mechanism is connected to the second mold and is used to drive the second mold to move closer to or away from the first mold. The first cutting component is positioned above the second mold and can penetrate the second mold; The second lifting mechanism is connected to the first cutting component and is used to drive the first cutting component to lift. The second cutting component is located below the first mold and can penetrate the first mold; The third lifting mechanism is connected to the second cutting component and is used to drive the second cutting component to lift.

[0005] Furthermore, the first mold and the second mold are arranged opposite to each other, and each of the first mold and the second mold has a groove on the side facing each other.

[0006] Furthermore, the grooves on the first mold and the second mold are spaced apart, and a tenon is provided between two adjacent grooves, so that the grooves on the first mold and the tenons on the second mold can be matched.

[0007] Furthermore, the first lifting mechanism, the second lifting mechanism, and the third lifting mechanism all include a ball screw and a slider that is threadedly engaged with the ball screw. The ball screw is rotatably connected to the frame, and the slider is slidably connected to the frame. A first drive mechanism is provided at one end of the ball screw.

[0008] Furthermore, both the first cutting assembly and the second cutting assembly include a cutting wheel and a second driving mechanism. The cutting wheel is connected to the output shaft of the second driving mechanism, and the second driving mechanism is slidably connected to the frame via its corresponding slider.

[0009] Preferably, it also includes a cutting chamber covering the first mold, the second mold, the first cutting assembly, and the second cutting assembly; a waste collection chamber is provided below the cutting chamber.

[0010] Preferably, it also includes a cutting depth sensor and a controller. The cutting depth sensor is used to detect the cutting depth of the cable by the first cutting component and the second cutting component. The controller is electrically connected to the cutting depth sensor, the second lifting mechanism and the third lifting mechanism, and is configured to control the operation of the second lifting mechanism and / or the third lifting mechanism based on the comparison result of the depth signal detected by the cutting depth sensor and a preset depth threshold.

[0011] Furthermore, the controller is configured to perform closed-loop control so that the actual cutting depth is stabilized within a preset depth threshold range.

[0012] Furthermore, it also includes a safety interlock device that is associated with the hatch of the cutting compartment. When the hatch is opened, the safety interlock device is triggered to cut off the power to the first cutting assembly and / or the second cutting assembly.

[0013] The present invention also provides a method for stripping cable sheaths, which uses the cable sheath stripping equipment described above to strip the cable sheaths, and includes the following steps: Pass the cable through the channel formed by the first mold and the second mold; Operate the first lifting mechanism to drive the second mold to descend so as to cooperate with the first mold to clamp and fix the cable; The first and second cutting components are activated to cut the cable's sheath; simultaneously, the second and third lifting mechanisms are operated to drive the first and second cutting components to rise and fall respectively, so as to adjust the cutting depth of the first and second cutting components to a preset value. During the cutting process, the stripped-off wrapping waste is collected.

[0014] This invention has at least the following advantages or beneficial effects: 1. This invention provides a mineral cable sheathing stripping device and method, employing a first mold, a second mold, and a first lifting mechanism that drives them to close, clamping and fixing the cable to effectively prevent shaking during the cutting process. Through the first cutting assembly, the second cutting assembly, and the second and third lifting mechanisms that drive them respectively, the sheathing can be automatically cut simultaneously from both the top and bottom sides of the cable, with precise control over the cutting depth. This not only significantly improves stripping efficiency but also completely avoids the safety risks of manual operation of cutting tools. The inclusion of a cutting chamber and a waste collection chamber encloses and collects the dust and debris generated during cutting, significantly reducing environmental pollution.

[0015] 2. By adding a cutting depth sensor and controller and implementing closed-loop control, the cutting depth can be monitored and automatically adjusted in real time, ensuring that the cutting process is always carried out within the preset safe depth range, fundamentally eliminating the risk of damaging the cable conductor due to excessive cutting. The safety interlock device automatically cuts off the cutting power when the hatch is opened, further ensuring the safety of the operators. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Please refer to Figures 1 to 5 As shown, the present invention provides a mineral cable sheathing stripping device, which includes a frame 1, a first mold 2, a second mold 3, a first lifting mechanism 4, a first cutting component 5, a second lifting mechanism 6, a second cutting component 7, and a third lifting mechanism 8.

[0021] The frame 1, serving as the basic support structure of the entire equipment, is typically constructed from welded steel profiles or assembled from high-strength aluminum alloy profiles. Its interior is divided into spaces for installing various functional modules. The first mold 2 is fixedly mounted on the frame 1, which has a horizontal mounting platform or beam for this purpose. The first mold 2 supports the cable to be processed. The second mold 3 is positioned directly above the first mold 2, with the two facing each other vertically. The second mold 3 is connected to the frame 1 via a first lifting mechanism 4, allowing it to move vertically towards or away from the first mold 2 under the drive of the lifting mechanism 4. When the second mold 3 descends and engages with the first mold 2, it clamps and secures the cable passing between them, effectively preventing radial runout of the cable during subsequent cutting. The first cutting assembly 5 is positioned above the second mold 3. The cutting component of the first cutting assembly 5 can move downwards and pass through a pre-drilled opening in the second mold 3 to cut the upper sheath of the cable located between the first mold 2 and the second mold 3. The second cutting component 7 is positioned below the first mold 2. Its cutting parts can move upwards and pass through a pre-drilled opening in the first mold 2 to cut the lower sheath of the cable. The first cutting component 5 and the second cutting component 7 cut simultaneously from above and below, resulting in a uniform cut of the sheath, making peeling easier and ensuring symmetrical force distribution, further enhancing the stability of the cutting process. The second lifting mechanism 6 is connected to the first cutting component 5 and is used to independently drive the first cutting component 5 to move up and down, thereby precisely adjusting its upper cutting depth on the cable. The third lifting mechanism 8 is connected to the second cutting component 7 and is used to independently drive the second cutting component 7 to move up and down, thereby precisely adjusting its lower cutting depth on the cable.

[0022] It should be noted that this equipment needs to be used in conjunction with a pay-off machine, a traction machine, and a take-up machine to form a complete automated production line: The cable is threaded into the equipment from the inlet end, passing through the channel formed between the first mold 2 and the second mold 3; the first lifting mechanism 4 is activated to press down the second mold 3, which, together with the first mold 2, secures the cable; then the first cutting component 5 and the second cutting component 7 are activated separately or simultaneously, and the cutting depth is adjusted to the preset value by the second lifting mechanism 6 and the third lifting mechanism 8; under the pull of the take-up machine, the cable passes through the equipment at a uniform speed, and its upper and lower wrapping layers are precisely cut, which can then be easily peeled manually or automatically. This equipment fundamentally solves the safety hazards of manual operation, greatly improves peeling efficiency, ensures a high degree of consistency in cutting depth, and greatly reduces the risk of cutting the conductor.

[0023] In this embodiment, to achieve stable clamping that adapts to different wire diameters, the first mold 2 and the second mold 3 employ a mating structure with specific surface profiles. For example... Figure 3 and Figure 4 As shown, the first mold 2 and the second mold 3 are arranged opposite to each other. The first mold 2 has multiple grooves 21 extending along the cable travel direction on the side closest to the second mold 3. The second mold 3 also has multiple grooves 21 extending along the cable travel direction on the side closest to the first mold 2. These grooves 21 are typically designed with a V-shaped cross-section. V-shaped grooves have good self-centering capabilities and can accommodate circular cables within a certain diameter range. When the cable is placed in the V-shaped groove 21 of the first mold 2, and the second mold 3 presses down, its V-shaped groove 21 makes linear contact with the upper surface of the cable, effectively limiting the horizontal movement of the cable. The angle and depth of the V-shaped grooves can be optimized according to the diameter range of the target cable.

[0024] Preferably, to provide better clamping force and prevent the cable from being squeezed out of the groove during clamping, the grooves 21 on the first mold 2 and the second mold 3 are designed with an alternating fit. Specifically, as shown in... Figure 4As shown, on the top surface of the first mold 2, an upwardly protruding tenon 22 is formed between two adjacent first mold grooves 21. Similarly, on the bottom surface of the second mold 3, a downwardly protruding tenon 22 is formed between two adjacent second mold grooves 21. When the second mold 3 descends to close with the first mold 2, the grooves 21 on the first mold 2 and the tenons 22 on the second mold 3 correspond to each other and nest together. At the same time, the grooves 21 on the second mold 3 and the tenons 22 on the first mold 2 correspond to each other and nest together. Through the interlocking structure, more and more uniform constraint points are formed in the circumference of the cable. When clamping force is applied to the cable, the cable is confined in multiple small cavities formed by the interlocking grooves and tenons, which greatly enhances the resistance to torsion and lateral slippage. This clamping method is more stable and reliable, especially for cables with smooth surfaces or when large traction forces are applied. Compared with simple upper and lower V-groove mating, this design significantly improves the reliability of clamping.

[0025] Please refer to Figure 5 As shown, the first lifting mechanism 4, the second lifting mechanism 6, and the third lifting mechanism 8 all employ ball screw drive schemes. These mechanisms include a ball screw 41 and a slider 42 that is threadedly engaged with the ball screw 41 via a ball nut. The upper part of the ball screw 41 is rotatably connected to the frame 1 via a bearing seat. The slider 42 is fixedly connected to the ball nut, and a guide portion is provided on the side of the slider 42. This guide portion slides in engagement with a linear guide rail fixed to the frame 1, thereby restricting the slider 42 to move only in the vertical direction and preventing it from rotating with the screw, ensuring linear accuracy and resistance to eccentric loads. A first drive mechanism 43 is provided at the upper end of the ball screw 41. The first drive mechanism 43 is preferably a handwheel, a servo motor, or a stepper motor, and its output shaft is directly connected to the end of the ball screw 41 via a coupling. In this embodiment, two first lifting mechanisms 4 are provided, located on both sides of the frame, and fixedly connected to both ends of the second mold 3, making the second mold 3 more stable when fixing cables. Furthermore, since the subsequent mechanisms involve the automatic adjustment of the second lifting mechanism 6 and the third lifting mechanism 8, the first drive mechanism 43 connected to the second lifting mechanism 6 and the third lifting mechanism 8 is a servo motor or a stepper motor. When the first drive mechanism 43 receives a control signal and rotates, it drives the ball screw 41 to rotate, which in turn converts into the linear lifting motion of the slider 42.

[0026] Please refer to Figure 1 and Figure 5As shown, both the first cutting assembly 5 and the second cutting assembly 7 employ a high-speed rotary cutting scheme. The first cutting assembly 5 and the second cutting assembly 7 have the same structure; taking the first cutting assembly 5 as an example, the first cutting assembly 5 includes a cutting wheel 51 and a second drive mechanism 52. The cutting wheel 51 is the cutting tool, preferably a thin metal cold-cutting saw blade in this embodiment, with a diameter of 180mm and a thickness of 2mm. This type of saw blade generates less heat, causes less deformation, and produces a smooth cut. The second drive mechanism 52 provides power for cutting, typically a dedicated cutting motor, such as a three-phase asynchronous motor, with speed regulation via a frequency converter. The cutting wheel 51 is directly mounted on the output shaft of the second drive mechanism 52 via a flange and a locking nut, rotating at high speed with the motor shaft. The housing of the second drive mechanism 52 is fixedly connected to the slider of the corresponding lifting mechanism via a motor mounting plate. Simultaneously, the motor mounting plate or the second drive mechanism 52 itself also has guide components that are slidably connected to the auxiliary guide rail on the frame 1. Therefore, when the second lifting mechanism 6 drives the slider on the second lifting mechanism 6 to rise and fall, it will drive the entire first cutting assembly 5 to rise and fall together, thereby realizing the adjustment of the cutting depth. The structure of the second cutting assembly 7 is mirror-symmetrical to that of the first cutting assembly 5. The first cutting assembly 5 and the second cutting assembly 7 are driven and adjusted independently, allowing either tool to be started, stopped, or adjusted individually according to process needs, providing great operational flexibility. For example, this design is particularly important when only one side of the coating layer needs to be peeled off, or when the thickness of the upper and lower coating layers is different.

[0027] Furthermore, the mineral cable sheathing stripping device of this embodiment also includes a protective and collection structure. Specifically, please refer to... Figure 1 As shown, a shell-like cutting chamber 9 is installed outside the first mold 2, the second mold 3, the first cutting assembly 5, and the second cutting assembly 7, completely enclosing the entire cutting operation area. The cutting chamber 9 is typically made of steel plate or transparent high-strength plastic sheeting and is fixed to the frame 1. It has an openable and closable door on the side for easy wire threading, adjustment, and observation. A waste collection chamber is connected directly below the cutting chamber 9. The waste collection chamber can be a drawer-type chip box or a collection container. When the equipment is running, metal chips, dust, and other waste generated during cutting will fall directly into the waste collection chamber under gravity and be effectively collected, preventing their spread into the workshop environment.

[0028] Preferably, the device further integrates an automatic monitoring and control system. This system includes a cutting depth sensor and a controller. The cutting depth sensor is used to detect the cutting depth of the cable by the first cutting component 5 and the second cutting component 7 in real time. In practical applications, the cutting depth sensor can be a non-contact laser displacement sensor or photoelectric sensor, installed near the cutting wheel to measure the distance between the cutting wheel's cutting edge and the surface of the cable conductor or a reference surface; it can also be a contact probe or encoder, indirectly calculating the cutting depth by measuring the displacement of the second lifting mechanism 6 and the third lifting mechanism 8. The controller is the core control unit of the device, typically including a programmable logic controller (PLC), an industrial computer (IPC), or an embedded microprocessor system. The controller's hardware includes a central processing unit (CPU), memory (RAM / ROM), digital / analog input / output (I / O) modules, communication interfaces, etc. The controller is electrically connected to the cutting depth sensor, the drive mechanism of the second lifting mechanism 6, and the drive mechanism of the third lifting mechanism 8. The controller is pre-programmed to continuously receive the depth signal detected by the cutting depth sensor and compare this real-time depth value with a preset depth threshold. Based on the comparison results, the controller generates control commands and sends them to the drive mechanism of the second lifting mechanism and / or the third lifting mechanism to control their actions, thereby driving the first cutting component 5 and / or the second cutting component 7 to rise or fall slightly, so that the actual cutting depth approaches the preset depth threshold.

[0029] Based on the above open-loop control logic, the controller can be further optimized to execute closed-loop control. The controller not only adjusts based on instantaneous errors but also combines the rate of change (derivative) and cumulative amount (integral) of the errors, using algorithms such as PID (Proportional-Integral-Derivative) control for calculation. The controller uses a preset depth threshold as the setpoint and the real-time feedback from the cutting depth sensor as the process variable, dynamically calculating and outputting the optimal control quantity to the second lifting mechanism 6 and the third lifting mechanism 8 through a PID algorithm. This closed-loop control effectively suppresses changes in cutting depth caused by interference factors such as slight fluctuations in cable diameter, tool wear, and mechanical clearances, ensuring that the actual cutting depth can be quickly, smoothly, and accurately stabilized within the preset depth threshold range. This completely eliminates the uncertainty and lag of manual adjustment based on experience, reducing the probability of conductor damage to near zero and guaranteeing high quality and consistency in the stripping operation.

[0030] To further enhance equipment safety, this embodiment also includes a safety interlock device. The safety interlock device is mechanically or electrically linked to the door of the cutting chamber 9. A common implementation is to install a limit switch or safety door lock sensor on the door frame as the safety interlock device. When the door is closed and locked, the contacts of the safety interlock device close or send a safety signal. When the operator opens the door, the safety interlock device is immediately triggered, its contacts open or the safety signal disappears. This signal is connected to the controller or directly to the power circuit of the cutting motor. Upon detecting the door opening signal, the controller immediately issues an emergency stop command; alternatively, the contacts of the safety interlock device directly cut off the power supply to the second drive mechanism 52 of the first cutting assembly 5 and / or the second drive mechanism of the second cutting assembly 7. This ensures that when the door needs to be opened for wiring, inspection, cleaning, or maintenance, the cutting blade automatically stops rotating, completely eliminating the risk of mechanical injury caused by accidental start-up during equipment maintenance or abnormal handling.

[0031] In addition, a touch screen human-machine interface can be integrated for parameter setting, status monitoring, and equipment start-up and shutdown operations, making equipment operation more intuitive and convenient.

[0032] This application also provides a method for stripping cable sheaths using the cable sheath stripping equipment described in any of the above embodiments. The method specifically includes the following steps: First, the end of the cable to be stripped is led out from the upstream cable feeding machine, then guided through the channel formed by the first mold 2 and the second mold 3, and the cable head is pulled onto the downstream cable take-up machine. During this process, ensure that the cable is roughly straightened.

[0033] Next, operate the first lifting mechanism 4 to drive the second mold 3 to descend, so that it cooperates with the first mold 2 below to clamp and fix the cable passing through it. The clamping force needs to be adjusted appropriately to prevent the cable from slipping and affecting the cutting accuracy, while avoiding excessive clamping force that could cause cable deformation.

[0034] Next, the cutting process is initiated and the depth is adjusted. The first cutting assembly 5 and the second cutting assembly 7 are activated, causing the cutting wheels to rotate at high speed. Simultaneously, the second lifting mechanism 6 and the third lifting mechanism 8 are operated to drive the first cutting assembly 5 and the second cutting assembly 7 towards the cable, respectively. The goal of the adjustment is to precisely adjust the cutting depth of the first cutting assembly 5 and the second cutting assembly 7 to a preset value, which is set according to the thickness of the cable sheath, ensuring that the sheath is cut through but the internal cable conductor is never touched.

[0035] Then, the downstream traction device is activated, pulling the cable continuously through the clamping and cutting equipment at a constant speed. As the cable travels at a uniform speed, the upper and lower cutting wheels continuously cut its sheath. The cut sheath, having lost its integrity, is easily peeled off from the conductor during subsequent winding or manual intervention.

[0036] Finally, during the entire cutting process, the debris and dust generated from the cable are confined within the sealed cutting chamber and fall into the waste collection chamber below under gravity or negative pressure for centralized collection, facilitating subsequent unified treatment and maintaining a clean working environment.

[0037] When the equipment is equipped with a controller and a cutting depth sensor, the "depth adjustment" step in the above method is upgraded to an automated closed-loop control process. Specifically, during cutting, the cutting depth sensor continuously detects the actual cutting depth and feeds the signal back to the controller. The controller compares this feedback signal with a preset depth threshold in real time and automatically generates control commands based on the comparison results, dynamically adjusting the actions of the second lifting mechanism 6 and the third lifting mechanism 8, thereby automatically stabilizing the actual cutting depth within the preset depth threshold range, achieving precise and adaptive control throughout the entire process.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
