Description

Technical Field

[0001] This utility model belongs to the technical field of pipe processing equipment, and in particular relates to a textile pipe cutting device. Background Technology

[0002] In the field of new energy vehicles, with the popularization of electric vehicles, higher requirements have been placed on battery safety, charging safety, and the protection of wiring harness systems. Textile tubing, as a commonly used protective sleeve for wiring harness systems, is mainly composed of fibrous materials.

[0003] However, in existing technologies, when cutting textile tubes, the fiber material easily melts when heated, resulting in residue at the cut. If this residue falls off during subsequent assembly or vehicle use, it will pose serious hazards: for example, if the residue enters the car's intake system or engine compartment, it may clog the air filter, intake pipes, or even damage precision internal engine components, leading to decreased engine performance or malfunction; if the residue enters the transmission or drivetrain, it may cause gear wear, bearing damage, and other problems, affecting the normal operation of the transmission system; in addition, some residue containing metallic components, if it falls onto the car's electrical wiring, may cause a short circuit, leading to electrical system malfunctions or even a fire risk.

[0004] Traditional cutting methods, such as ordinary mechanical cutting, often cannot avoid the problem of material melting caused by frictional heat. Therefore, how to effectively avoid or eliminate the residue generated by material melting during the cutting process of textile tubes, improve the cutting quality, and ensure the cleanliness of automotive parts and the safety and reliability of overall operation are technical problems that urgently need to be solved in this field.

[0027] This embodiment provides a textile tube cutting device 1, such as... Figures 1-4 As shown, it includes:

[0028] Base 10;

[0029] The power mechanism 20, mounted on the base 10, is used to provide rotational driving force;

[0030] The cutting unit 30 is rotatably connected to the base 10 and driven by the power mechanism 20 to perform a cutting operation around the textile tube to be cut. The cutting unit 30 includes at least one cutting blade 304 and a temperature control heating mechanism that cooperates with the at least one cutting blade 304. The temperature control heating mechanism is used to control the temperature of the cutting blade 304.

[0031] The feeding mechanism 40 includes a guide section and a drive section. The guide section is located in the axial region of the cutting unit 30, while the drive section is connected to and moves relative to the base 10, used to axially transport the textile tube to the cutting position of the cutting unit 30; and

[0032] Cooling mechanism 50 is fixedly connected to cutting unit 30. Cooling mechanism 50 is configured to cool the cutting position of textile tube and / or cutting tool 304 during the process of cutting unit 30 performing circumferential cutting on textile tube.

[0033] In a more specific embodiment, the base 10 can be a robust frame, such as a cast iron or welded steel structure, providing an installation reference and stability for the entire device, and other auxiliary mechanisms can be mounted on the base 10. The power mechanism 20 can specifically be a high-precision servo motor or stepper motor with a reducer, connected to the rotating component of the cutting unit 30 via a coupling or synchronous belt to precisely control the rotation speed and start / stop of the cutting unit 30. The rotating component of the cutting unit 30 can be a hollow rotary table or sleeve structure, on which at least one radially movable cutting blade 304 is mounted. The temperature control heating mechanism can be integrated into the blade holder of the cutting blade 304, for example, using resistance wire heating or induction heating, and the temperature of the cutting blade 304 can be monitored and adjusted in real time by a temperature sensor (such as a thermocouple) and a temperature controller (such as a PID controller) to ensure that it operates at a preset optimized cutting temperature point for textile tube materials. The guide section of the feeding mechanism 40 can be a fixed or retractable mandrel or guide tube positioned along the rotation axis of the cutting unit 30, with the textile tube sleeved on its exterior. Its drive section can be one or more pairs of motor-driven pressure rollers or tracked traction devices mounted on the base 10, used to axially feed the textile tube into the cutting unit 30 at a set speed. The cooling mechanism 50 can employ a circulating cooling system to cool the cutting position of the textile tube. Through the coordinated operation of the above structures, the heated cutting blade 304 rotates to circumferentially cut the textile tube, ensuring a clean cut, while the cooling mechanism 50 rapidly cools the cut, effectively suppressing residue generation.

[0034] In some embodiments, the cutting unit 30 further includes a cutting platform 301, at least one textile tube clamp 302, and a driving mechanism 303; the cutting platform 301 has a cutting area at its center, and the output end of the guide portion of the feeding mechanism 40 is disposed within the cutting area; the driving mechanism 303 is disposed on the cutting platform 301 and is poweredly connected to the textile tube clamp 302 and the cutting tool 304 respectively, and the textile tube clamp 302 and the cutting tool 304 face the cutting area; the driving mechanism 303 is used to drive the textile tube clamp 302 to clamp and fix the textile tube during cutting, and is also used to drive the cutting tool 304 to feed radially into the textile tube and cut the textile tube.

[0035] In one specific embodiment, the cutting platform 301 within the cutting unit 30 can be a disc or polygonal platform fixed to the rotating component of the cutting unit 30, with a cutting area at its center allowing the textile tube to pass through. The drive mechanism 303 may include at least one small cylinder, linear motor, or small cam-linkage mechanism branching from the main rotational power, mounted on the cutting platform 301, for driving at least one textile tube clamp 302 (e.g., a pneumatic gripper or mechanical gripper finger) to radially clamp the textile tube. Simultaneously, the drive mechanism 303 or another independent drive component (also a cylinder, linear motor, or cam mechanism) drives at least one cutting cutter 304 (e.g., a cutter holder mounted on a sliding guide rail) to radially feed after the textile tube is clamped, and the rotating cutting unit 30 drives the cutter to complete the circumferential cutting action. The output end of the guide portion of the feeding mechanism 40, such as the end of a mandrel or the outlet of a guide tube, is precisely positioned within the cutting area, ensuring that the textile tube is well supported and accurately positioned during cutting.

[0036] In some embodiments, the number of cutting blades 304 and textile tube clamps 302 are two or more, and the driving mechanism 303 drives multiple textile tube clamps 302 and multiple cutting blades 304 to simultaneously feed radially toward the textile tube to clamp the textile tube and cut it, and then synchronously retracts radially to separate after cutting.

[0037] In one specific embodiment, there can be two cutting blades 304 and two textile tube clamps 302, symmetrically arranged on both radial sides or around the textile tube. The drive mechanism 303 can be designed with a synchronous linkage mechanism, such as a gear and rack, synchronous pulley, or electronic synchronous control system, to ensure that the two or more textile tube clamps 302 can simultaneously move radially toward the center of the textile tube and clamp, and then the two or more cutting blades 304 also synchronously feed radially to cut. After cutting, the drive mechanism 303 drives the clamps and blades to synchronously retract radially, preparing for the feeding and cutting of the next textile tube. This multi-point synchronous clamping and cutting method helps to improve the stability of clamping and cutting efficiency, and may make the cutting force more uniform.

[0038] In some embodiments, the feeding mechanism 40 includes a guide rod 401 and a support fixture 402 sleeved on the output end of the guide rod 401; the inlet of the support fixture 402 is formed with a semi-conical structure to assist the introduction of the textile tube and maintain its open state, and the support fixture 402 integrates at least one cooling element of the cooling mechanism 50 for cooling the cutting part of the textile tube.

[0039] In one specific embodiment, the guide rod 401 in the feeding mechanism 40 can be a fixed or replaceable precision round rod according to the specifications of the textile tube, installed at the feed end of the device and extending to the cutting area. The support fixture 402 can be a quick-replaceable bushing or positioning sleeve fitted onto the end of the guide rod 401, with its inlet end machined into a semi-conical flared mouth to facilitate the smooth introduction of the textile tube and prevent the tube opening from being scratched or deformed during entry. The interior of the support fixture 402 can be designed with annular or porous cooling channels. These channels, as part of the cooling elements of the cooling mechanism 50, are directly connected to the cooling medium (such as cooling water or cooling air), allowing the cooling medium to directly act on the outer surface of the textile tube to be cut or very close to the cutting area, achieving precise and efficient cooling of the cutting part.

[0040] In some embodiments, the cooling mechanism 50 is a water-cooling device that dissipates heat by providing circulating cooling water channels inside the support fixture 402 and in the area adjacent to the cutting tool 304.

[0041] In one specific embodiment, the cooling mechanism 50 is a water-cooling device. This device may include a water pump, a water tank, cooling water circulation pipes, and a filter. The support fixture 402 has precisely machined internal circulating cooling water channels through which cooling water circulates, carrying away the heat generated during cutting. Simultaneously, cooling water channels are also provided near the mounting bases of the multiple cutting blades 304 or near the blades themselves to cool the blades, preventing overheating that could affect their performance and lifespan, and further reducing heat transfer to the textile tube. The entire water-cooling system forms a closed-loop or open-loop cooling circuit, effectively controlling the temperature of the cutting area at a low level.

[0042] In some embodiments, the cutting blade 304 is made of a high-temperature resistant material to adapt to the operating temperature of the temperature-controlled heating mechanism and the cutting operation.

[0043] In one specific embodiment, the cutting tool 304 can be made of a material with good high-temperature resistance and cutting performance, such as high-speed steel, cemented carbide, or special ceramic materials. These materials can withstand the operating temperature set by the temperature-controlled heating mechanism (e.g., a temperature slightly higher than the melting point of the textile tube material) without softening, deforming, or rapid wear, while ensuring the sharpness and durability of the cutting edge, thus ensuring cutting quality and efficiency.

[0044] In some specific embodiments, the power mechanism 20 includes a servo motor for driving the cutting unit 30 to rotate with high precision to cut the textile tube.

[0045] In one specific embodiment, the drive motor in the power mechanism 20 is a servo motor. This servo motor, through its encoder and servo driver, enables precise closed-loop control of the rotation angle, speed, and acceleration of the cutting unit 30. This allows the cutting unit 30 to rotate with high precision at a set, constant, or variable speed, thereby ensuring that the cutting trajectory of the cutting tool 304 on the circumference of the textile tube is accurate, the cut perpendicularity is good, and the consistency and accuracy of the cutting are improved.

[0046] In some embodiments, the cutting device 1 further includes a central control system consisting of a programmable logic controller and a touch screen. The central control system is electrically connected to and coordinates the cooperative operation of the power mechanism 20, the feeding mechanism 40, the drive mechanism 303 in the cutting unit 30, the temperature control heating mechanism, and the cooling mechanism 50.

[0047] In one specific embodiment, the automated control of the cutting device 1 is achieved by a central control system. The core of this system is a programmable logic controller (PLC), and a touchscreen is responsible for human-machine interaction. The PLC is electrically connected via input / output modules to the power mechanism 20 (e.g., a servo driver), the drive motor or actuator of the feeding mechanism 40, the drive mechanism 303 within the cutting unit 30 (e.g., a cylinder solenoid valve or motor driver controlling the clamps and cutters), the temperature controller of the temperature control heating mechanism, and the pump or valve of the cooling mechanism 50. The operator sets parameters such as cutting length, cutter temperature, and cutting speed via the touchscreen. The PLC coordinates and controls the sequence of actions, start / stop times, and motion parameters of each mechanism according to a preset program, realizing a series of actions such as automatic feeding, clamping, heating and cutting, cooling, and releasing of the textile tube. It can also perform fault diagnosis and display production data.

[0048] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations, but obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this invention.
