[0031] Example 1

[0032] like Figure 1-3As shown, this embodiment discloses a stripping device for a dust-free drag chain core wire, comprising a support mechanism 3, a clamping and stripping mechanism 1, and a pneumatic control system 2; the pneumatic control system 2 is connected to the support mechanism 3; the clamping and stripping mechanism 1 comprises an upper clamping block 101 and a lower clamping block 102, and the upper clamping block 101 is connected to the pneumatic control system 2 and is arranged as a whole on the upper part of the support mechanism 3; the lower clamping block 102 is arranged at the lower part of the support mechanism 3; and also includes an intelligent control system, which is installed on the support mechanism 3 and is electrically connected to the pneumatic control system 2 and the clamping and stripping mechanism 1.

[0033] The pneumatic control system 2 includes several air inlet pipes, a solenoid valve 203, a clamping cylinder 201, and a peeling cylinder 202. One end of the air inlet pipe is connected to the solenoid valve 203, and the other end is connected to the clamping cylinder 201 or the peeling cylinder 202. The solenoid valve 203 is also connected to an electrical controller to control the opening and closing of the solenoid valve 203, thereby controlling the up and down movement of the telescopic rods inside the clamping cylinder 201 and the peeling cylinder 202. The electrical controller uses a foot switch, a manual switch, or an intelligent control system. When the foot switch is used as the electrical controller, the solenoid valve 204 is connected to the air source through the air inlet pipe and is responsible for controlling the operation of the telescopic rods inside the clamping cylinder 201 and the peeling cylinder 202. When the foot switch is pressed, the solenoid valve 204 opens, and the air source enters the clamping cylinder 201 and the peeling cylinder 202 through the air inlet pipe, causing the cylinders to press down. When the foot switch is released, the solenoid valve 204 closes and the cylinders return to their original position.

[0034] The upper clamping block 101 and the lower clamping block 102 are connected via a sliding track; the lower telescopic rod of the peeling cylinder 202 is connected to a telescopically movable mechanical feed group 3.

[0035] The mechanical feed group 3 is divided into an upper feed group 301 and a lower feed group 302; the upper feed group 301 is provided with a first vertical pressing block 303 and a first horizontal pressing block 1034; the first vertical pressing block 303 and the first horizontal pressing block 1034 are connected by a first horizontal telescopic rod 1035; the lower feed group 302 is provided with a second vertical pressing block 1036 and a second horizontal pressing block 1037; the second vertical pressing block 1036 and the second horizontal pressing block 1037 are connected by a second horizontal telescopic rod 1035. Rod 1038 is connected; the first horizontal telescopic rod 1035 and the second horizontal telescopic rod 1038 are respectively connected to the peeling cylinder 202 through the air pipe to drive the movement; the lower end surface of the first horizontal pressing block 1034 is fixed with an upper cutter 104 and an upper peeling knife 105; the upper end surface of the second horizontal pressing block 1037 is fixed with a lower cutter 106 and a lower peeling knife 107; the upper cutter 104 and the lower cutter 106 are arranged opposite to each other, and the upper peeling knife 105 and the lower peeling knife 107 are arranged opposite to each other.

[0036] The upper cutter 104 and the lower cutter 106 are mainly responsible for cutting the outer skin of the wire, and are respectively independently arranged with the upper stripping knife 105 and the lower stripping knife 107. The upper stripping knife 105 and the lower stripping knife 107 are respectively adjacent to the upper cutter 104 and the lower cutter 106, and their function is to strip the cut outer skin from the core wire of the wire.

[0037] Under the action of the clamping cylinder 201, the upper clamping block 101 moves downward along a sliding track, clamping the wire together with the lower clamping block 102 to ensure that the wire does not move or tilt during the cutting and stripping process. After clamping the wire, the stripping cylinder 202 controls its downward movement through the solenoid valve 203. The upper and lower cutters 104 simultaneously act on the wire sheath, making circular cuts at the predetermined stripping location. After the cut is completed, the stripping cylinder 202 further pushes the stripping knife to remove the wire sheath from the incision. After stripping is completed, the stripping cylinder 202 and the clamping cylinder 201 are reset by the pneumatic system. The upper clamping block 101 and upper stripping knife 105 return to their initial positions, releasing the clamped area of the wire and completing the stripping process.

[0038] Example 2

[0039] like Figure 1-3 As shown, this embodiment discloses another stripping device for dust-free drag chain core wires, which is similar to the embodiment 1, except that:

[0040] The intelligent control system includes a PLC intelligent control system, which controls the opening and closing of the electromagnetic valve 203 and detects the movement of the peeling cylinder 202 through a sensor.

[0041] The PLC can control the opening and closing of the solenoid valve, thereby precisely controlling the downward pressure and return movement of the cylinder. Through pre-set programs, the PLC can automatically adjust the pressure and movement speed of the stripping cylinder according to the specifications of the wire, ensuring the accuracy of the stripping process.

[0042] Support mechanism 3 is connected to a human-machine interface (HMI), which incorporates a programmable logic controller (PLC) intelligent control system. This system incorporates automatic detection and alarm functions, automatically responding to and alerting the operator when an anomaly occurs during operation. Sensors monitor the peeling mechanism's operating status in real time. If a malfunction is detected in the peeling cylinder 202, cutter, peeling blade, or other key components (e.g., a jam, insufficient air pressure, or incomplete peeling), the control system automatically stops operation and displays an error message on the HMI screen, alerting the operator to address the issue promptly.

[0043] Pressure sensors are installed on the stripping cylinder 202 and the cutting and stripping device to monitor the pressure applied during the stripping process in real time. The PLC intelligent control system automatically adjusts the air pressure in the stripping cylinder 202 based on sensor feedback signals. A position sensor is installed on the sliding track to monitor the position of the cutting and stripping knives in real time. A laser rangefinder or photoelectric sensor is also included in the stripping area to detect the diameter of the stripped wire in real time. The laser rangefinder or photoelectric sensor is electrically connected to the PLC intelligent control system. When the wire enters the stripping area, the laser rangefinder or photoelectric sensor installed on the cutting and stripping device can detect the wire diameter in real time. Based on the detection results, the PLC intelligent control system automatically adjusts the cutting depth of the stripping cylinder 202 and the position of the stripping knife, ensuring that each stripping process can adapt to wires of different specifications and reducing errors caused by manual adjustments.

[0044] The PLC system automatically adjusts stripping parameters to accommodate the stripping needs of multi-core wires, and the device is capable of stripping multiple wires at once. The control system automatically adjusts the position of the cutter and stripper according to the size and material of each wire core, ensuring uniform and undamaged stripping of all wire cores. Workers can select different wire types (such as PVC, rubber, nylon, and other materials) through the HMI interface. The PLC system automatically selects the appropriate stripping force and cutting depth based on the hardness and thickness of the wire material, ensuring optimal stripping results for each wire. The parameters of each stripping operation (such as wire type, stripping length, stripping depth, and air pressure setting) can be recorded and stored within the human-computer interaction system.

[0045] Example 3

[0046] like Figure 1-3 As shown, this embodiment discloses another stripping device for dust-free drag chain core wires, which is similar to the embodiment 1, except that:

[0047] The upper telescopic end of the clamping cylinder 201 is connected to a tension adjustment knob 2011; the upper telescopic end of the peeling cylinder 202 is connected to a cutter adjustment knob 2021 and a peeling knife adjustment knob 2022. The support mechanism 3 comprises an upper support base 301, a lower support base 302, and a connecting plate 303 disposed between the upper and lower support bases 301 and 302. The clamping cylinder 201 and peeling cylinder 202 are fixed to the upper support base 301. A cushioning foot pad 3021 is provided at the bottom of the lower support base 302 to reduce noise and structural displacement caused by mechanical vibration during the peeling process.

[0048] The tension adjustment knob 2011 adjusts the vertical height of the upper clamping block 101, thereby changing the degree of clamping of the upper and lower clamping blocks 101, 102 on the stripped wire, ensuring that the wire to be stripped does not slide excessively during operation. The cutter adjustment knob 2021 adjusts the cutting depth. After adjustment, the upper and lower cutters 104, 106 can be finely adjusted in the vertical direction to accommodate the thickness of the outer sheath of wires of different diameters, ensuring that the cutting depth is sufficient to cut the outer sheath without damaging the metal core inside the wire. The stripping knife adjustment knob 2022 controls the position of the stripping knife. It can be adjusted up and down as needed to ensure that the upper and lower stripping knives 105, 107 provide appropriate protection to the wire core when stripping the outer sheath, avoiding damage to the wire core, while also ensuring consistent stripping length.

A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
