Description

Technical Field

[0001] This utility model relates to the field of wire processing equipment technology, and more specifically, to a pipe cutting structure. Background Technology

[0002] In the production and processing of high-speed data cables for servers and other types of cables, it is usually necessary to install a tubing around the cable to achieve functions such as insulation, protection, or shielding. Common types of tubing include nylon tubing and metal tubing. Before installing the tubing, the rolled tubing needs to be cut into appropriate short sections according to the actual length requirements of the cable.

[0003] However, existing technologies mostly use direct mechanical cutting for cutting pipelines. Since the pipeline itself is a braided structure, this traditional cutting method has significant drawbacks: the braided structure at both ends of each cut pipeline section is prone to loosening and unraveling, which not only results in an irregular appearance of the pipeline but also affects the subsequent installation and coordination with wires—the loose ends may snag on wires or equipment components during installation, reducing installation efficiency; more seriously, if the loose parts are used directly without treatment, it will shorten the service life of the pipeline and even affect the overall performance of the wires, such as causing problems such as reduced insulation and shielding.

[0004] Furthermore, traditional pipe cutting and subsequent pipe threading are mostly separate manual operations: first, the pipe is cut manually, and then the wire is threaded manually into the cut pipe. This process not only requires a high level of operator skill but also has extremely low overall efficiency, making it difficult to meet the needs of large-scale, automated production. This is especially true in scenarios involving large-volume wire processing, where the efficiency bottleneck of manual operation becomes even more pronounced and cannot match the cycle time requirements of modern production lines. Therefore, this invention proposes a pipe cutting structure to at least partially solve the above problems. Utility Model Content

[0005] In view of the above problems, this utility model proposes a pipe network cutting structure to overcome or at least partially solve the above problems. It is suitable for cutting and processing nylon or metal pipe networks used as outer sheaths for high-speed server data cables and other cables, enabling precise cutting and end-fragmentation prevention, while improving the efficiency of subsequent cable threading.

[0006] To address the aforementioned problems, this utility model discloses a pipeline cutting structure, comprising: The feeding mechanism, cutting mechanism, and conveying mechanism are arranged sequentially. The cutting mechanism includes: a first support frame and heating moving blocks symmetrically arranged on the frame, with cutting heads at opposite ends of the heating moving blocks; the cutting heads have semi-circular blades. The heating moving block is equipped with a heating component for heating the cutting head to a preset temperature.

[0007] Optionally, a first slide rail is vertically provided on the first support frame; The first slider is slidably mounted on the first slide rail; the heating moving block is fixedly connected to the first slider via a connecting rod. The heating moving block is connected to the cylinder via a connector.

[0008] Optionally, the feeding mechanism includes: a second support frame on which a first motor is mounted; The first pressing assembly includes a third support frame, on which a fixed wheel and a second slide rail are provided; a second slider is slidably connected to the second slide rail. The movable wheel is mounted on the second slider; The third support frame is also provided with a clutch component connected to the second slider; Two symmetrically distributed conveyor wheels are also provided between the third support frame and the heating moving block; a transmission wheel is coaxially connected to the back of one of the conveyor wheels, and the transmission wheel is connected to the output position of the first motor via a belt.

[0009] Optionally, a counting sensor is also provided on the back of the third support frame; The axis of the fixed wheel passes through the third support frame and is connected to the trigger wheel; The trigger wheel is matched with the counting sensor.

[0010] Optionally, a tension wheel is also provided on the back of the second support frame; The tension wheel abuts against the inner or outer side of the belt.

[0011] Optionally, the output end of the first motor and the transmission wheel are both gears, and the belt is a toothed belt.

[0012] Optionally, the conveying mechanism includes a fourth support frame; The front of the fourth support frame is vertically provided with at least one set of third slide rails; Each group of third slide rails slides to connect two groups of third sliders; The third slider is provided with a material threading wheel; wherein, the material threading wheel is provided with an annular groove in the radial direction (the annular groove can be matched with the conduit, so that the material threading wheel can contact the pipeline with a large area). The fourth support frame also has a vertically placed elongated hole; the shaft of the material threading wheel passes through the third slider and the elongated hole, and is connected to the shaft of the transmission gear through a telescopic universal joint shaft; The transmission gear is connected to the power gear via a speed-changing gear; the power gear is connected to the output end of the second motor.

[0013] Optionally, the heating component is a heating rod.

[0014] Optionally, it also includes a smoke exhaust duct, which is located above the first support frame.

[0015] Optionally, a smoke exhaust fan is also provided at the lower end of the smoke exhaust duct.

[0016] The embodiments of this utility model have the following advantages: The cutting head is heated to a preset temperature by a heating component. During high-temperature cutting of the pipe network, the cut area is simultaneously melted, solidifying the ends of the braided structure. This completely avoids the loosening and fraying problems at the pipe network ends caused by traditional cutting methods, ensuring a neat appearance and structural integrity of the pipe network and improving the smoothness of subsequent installation operations. In the feeding mechanism, the meshing transmission of the toothed belt and gears ensures a stable pipe network conveying speed. The cooperation of the counting sensor and the trigger wheel accurately measures the conveyed length of the pipe network, achieving automatic cutting of the preset length, reducing manual intervention, improving cutting accuracy and efficiency, and meeting the needs of large-scale production. The cutting mechanism and the conveying mechanism work together. After cutting, a conduit can be used as a transition piece to pull the cut pipe network out from the rear end of the conduit and wrap it around the cable end. Then, the cable and pipe network are pulled out together from the conduit. Compared with traditional manual pipe threading operations, efficiency can be increased by approximately 6 times, significantly shortening the overall processing cycle. The installation of smoke exhaust ducts and exhaust fans can promptly remove fumes generated during high-temperature cutting, preventing smoke accumulation from affecting equipment or operators and improving the working environment.

Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 5 In some embodiments of this utility model, a pipe network cutting structure includes a feeding mechanism, a cutting mechanism, and a conveying mechanism arranged sequentially; the cutting mechanism includes a first support frame 100 and heating moving blocks 101 symmetrically arranged on it, the opposite ends of the heating moving blocks 101 are provided with cutting heads 102; the cutting heads 102 are provided with semi-circular cutting edges; the heating moving blocks 101 are provided with heating components 103 for heating the cutting heads 102 to a preset temperature.

[0020] During operation, the feeding mechanism conveys the conduit. The conduit passes between the conveying mechanism and the cutter head 102, reaching the rear end of the feeding mechanism. Because the conduit is made of metal, its surface is relatively smooth, and its end is relatively thin, allowing the feeding mechanism to pass the conduit outside the conduit and ensure the conduit reaches at least the position of the conveying mechanism. At this point, the conveying mechanism and the feeding mechanism work together to stretch the conduit (which is a braided structure, its length is extendable) to its normal state and to the length required to fit the target wire. When the cutter head 102 is heated to a preset temperature, the two cutter heads 102 move along the heating moving block 101. The two semi-circular cutting edges move closer together, forming a circular cutting edge that covers the conduit. High temperature cuts the conduit mesh, melting the cut edge to prevent the mesh from easily spreading and becoming damaged, as is common in traditional cutting methods. After cutting, one end of the cable is inserted into the conduit, and then the cut mesh is pulled out from the rear, covering the cable end. The cable and mesh are then pulled out together (since the mesh length is less than the cable length). This efficient and fast method improves efficiency by approximately six times compared to traditional manual conduit installation.

[0021] The system comprises a feeding mechanism, a cutting mechanism, and a conveying mechanism arranged sequentially. The cutting mechanism includes a first support frame 100 and symmetrically arranged heating moving blocks 101. The heating moving blocks 101 have a semi-circular cutting head 102 at their ends and a heating component 103 inside. On one hand, the semi-circular cutting head closes to form a circular cutting head, which is adapted to the conduit and achieves precise cutting of the conduit network. On the other hand, the heating component 103 heats the cutting head 102, melting the end of the conduit network while cutting, thus completely solving the problem of loose ends in traditional cutting. Through the coordinated operation of the feeding, cutting, and conveying mechanisms, the cutting and conduit threading operations are connected, which improves the efficiency by about 6 times compared to manual conduit threading, greatly improving processing efficiency and saving labor costs.

[0022] The first support frame 100 is vertically provided with a first slide rail 104; the first slider 105 is slidably disposed on the first slide rail 104; the heating moving block 101 is fixedly connected to the first slider 105 through a connecting rod 109; the heating moving block 101 is connected to the cylinder through a connecting member 107. Specifically, the upper heating moving block 101 is connected to the first cylinder 106 through the connecting member 107, and the lower heating moving block 101 is connected to the second cylinder 108 through the connecting member 107. The first cylinder 106 and the second cylinder 108 can be the same cylinder or different cylinders, which can be set according to actual application requirements.

[0023] The aforementioned first support frame 100 is provided with a vertical first slide rail 104, and a first slider 105 slides on the first slide rail 104. The heating moving block 101 is fixed to the first slider 105 through a connecting rod 109 and connected to the cylinder through a connecting piece 107. The cooperation between the first slide rail 104 and the first slider 105 ensures that the heating moving block 101 moves smoothly and avoids the cutting head 102 from deviating, which would cause inaccurate cutting position. By driving the heating moving block 101 through the aforementioned cylinder, the closing speed and pressure of the cutting head 102 can be precisely controlled, adapting to pipe networks of different thicknesses and materials, and improving cutting applicability.

[0024] Furthermore, the feeding mechanism includes: a second support frame 200, on which a first motor 201 is mounted; a first pressing assembly, including a third support frame 202, on which a fixed wheel 207 and a second slide rail 211 are mounted; a second slider 212 is slidably connected to the second slide rail 211; a movable wheel 208 is disposed on the second slider 212; the third support frame 202 is also provided with a clutch 209 connected to the second slider 212, for controlling the separation and pressing states of the movable wheel 208 and the fixed wheel 207; two conveying wheels 203 are also provided between the third support frame 202 and the heating moving block 101, symmetrically distributed above and below; a transmission wheel 204 is coaxially connected to the back of one of the conveying wheels 303, and the transmission wheel 204 is connected to the output position of the first motor 201 through a belt 205. During operation, the pipeline passes between the moving wheel 208 and the fixed wheel 207. The clutch 209 presses the pipeline between the moving wheel 208 and the fixed wheel 207. During transport, friction drives the moving wheel 208 and the fixed wheel 207 to rotate. The pipeline passes through two conveying wheels 203. One of the conveying wheels 203 is driven to rotate by the first motor 201, and the other conveying wheel rotates under the influence of friction. Figure 2 As shown, the conveyor wheel 203 can be provided with corresponding textures to ensure increased friction when in contact with the pipeline network and prevent slippage during conveying.

[0025] The clutch 209 controls the pressing and separating of the moving wheel 208 and the fixed wheel 207, achieving stable clamping and release of the pipeline network and preventing pipeline deviation during transportation. The first motor 201, preferably a servo motor, drives the conveyor wheel 203 through the belt 205 to achieve automated pipeline transportation and reduce manual intervention. The surface of the conveyor wheel 203 can be provided with anti-slip textures, such as horizontal and vertical or toothed patterns, to increase friction with the pipeline network, prevent slippage during transportation, and ensure the accuracy of the transportation length.

[0026] Furthermore, a counting sensor 214 is also provided on the back of the third support frame 202; the axis of the fixed wheel 207 passes through the third support frame 202 and is connected to a trigger wheel 213; the trigger wheel 213 is matched with the counting sensor 214. By having the trigger wheel 213 rotate synchronously with the fixed wheel 207, the counting sensor accurately measures the pipeline conveying length by sensing a trigger signal; this achieves automatic cutting of preset lengths, avoids errors from manual measurement, improves cutting accuracy, and meets the needs of pipeline processing for different lengths.

[0027] It should be noted that the aforementioned fixed wheel 207 refers to its position not being displaced, and should not be interpreted as not being able to rotate.

[0028] In some embodiments of this application, a tension wheel 206 is further provided on the back of the second support frame 200; the tension wheel 206 abuts against the inner or outer side of the belt 205; in this application, the tension wheel 206 is preferably located on the outer side of the belt 205. The tension of the belt 205 can be adjusted by adjusting the position of the tension wheel 206 to avoid transmission slippage caused by belt slack; ensuring the transmission synchronization of the first motor 201 and the conveying wheel 203, and further improving the stability of the pipeline conveying speed and length.

[0029] Furthermore, both the output end of the first motor 201 and the transmission wheel 204 are gears, and the belt 205 is a toothed belt. The meshing transmission of the gears and the toothed belt completely eliminates the problem of belt slippage and ensures 100% transmission efficiency; thereby ensuring that the rotational speed of the conveying wheel 203 is completely synchronized with the output speed of the first motor 201, maximizing the accuracy of pipeline conveying length, and is especially suitable for high-precision cutting scenarios.

[0030] The aforementioned conveying mechanism includes a fourth support frame 300; the front of the fourth support frame 300 is vertically provided with at least one set of third slide rails 302; each set of third slide rails 302 is slidably connected to two sets of third sliders 301; the third sliders 301 are provided with a material threading wheel 303; wherein, the material threading wheel 303 is radially provided with an annular groove, wherein the annular groove can match the conduit, so that the material threading wheel can contact the pipeline with a large area; the fourth support frame 300 is also vertically provided with an elongated hole; the axis of the material threading wheel 303 passes through the third slider 301 and the elongated hole, and is connected to the axis of the transmission gear 306 through a telescopic universal joint shaft 307; the transmission gear 306 is connected to the power gear 305 through a speed-changing gear; the power gear 305 is connected to the output end of the second motor 304. The annular groove of the threading wheel 203 adapts to the threading tube, ensuring stable positioning and conveying of the tube and providing support for subsequent threading operations. The telescopic universal joint shaft 307 can accommodate the sliding of the threading wheel 303 along the slide rail, ensuring continuous power transmission. When the threading wheel 303 slides, the distance between the axis of the threading wheel 303 and the axis of the transmission gear 306 will change. The telescopic universal joint shaft 307 can adapt well to the above-mentioned distance change while transmitting power. The speed-changing gear can adjust the rotation speed of the threading wheel 303 to adapt to different threading speed requirements and improve the flexibility of the threading operation.

[0031] Furthermore, the heating component 103 is a heating rod. The heating rod provides uniform heating and high temperature control precision, allowing for accurate adjustment of the cutting head temperature based on the pipe network material (such as nylon or metal). The heating rod also features a simple structure, low failure rate, and long service life, reducing equipment maintenance costs.

[0032] In some embodiments of this application, such as Figure 5 As shown, it also includes a smoke exhaust duct 401, which is located above the first support frame 100. The smoke exhaust duct 401 collects fumes generated during high-temperature cutting of the pipe network (especially those made of polymer materials), preventing smoke accumulation; preventing smoke from contaminating equipment components or affecting the health of operators, and improving the working environment.

[0033] Furthermore, a smoke exhaust fan 402 is also provided at the lower end of the smoke exhaust duct 401. The smoke exhaust fan 402 provides suction to accelerate the entry and discharge of smoke into the smoke exhaust duct, thereby improving smoke exhaust efficiency; the fan speed can be adjusted according to the amount of smoke generated, balancing smoke exhaust effect and energy consumption, and improving the practicality of the equipment.

[0034] As an example, the equipment initialization and installation preparation are as follows: First, one end of the rolled pipe network to be cut is pulled to the feeding mechanism, and the clutch 209 of the first pressing assembly is controlled to move, causing the second slider 212 to move upward along the second slide rail 211, so that the moving wheel 208 separates from the fixed wheel 207, and one end of the pipe network passes through the gap between the moving wheel 208 and the fixed wheel 207; then, the clutch 209 is reset, causing the moving wheel 208 to move downward, so that the moving wheel 208 and the fixed wheel 207 press the pipe network together, realizing the initial clamping of the pipe network.

[0035] Continue pulling one end of the pipeline, so that it passes between the two symmetrical conveying wheels 203 in the feeding mechanism, until one end of the pipeline passes through the gap between the two cutting heads 102 in the cutting mechanism and extends to the material threading wheel 303 of the conveying mechanism; at the same time, pass the threading tube through the position between the material threading wheel 303 and the cutting head 102 of the conveying mechanism, so that one end of the threading tube reaches the rear end of the feeding mechanism, the pipeline is sleeved on the outside of the threading tube, and the pipeline extends at least to the position of the conveying mechanism.

[0036] Pipeline conveying and length measurement: The first motor 201 of the feeding mechanism is started. The output end (gear) of the first motor 201 drives the transmission wheel 204 (gear) to rotate through the toothed belt 205, which in turn drives the conveying wheel 203 coaxially connected to the transmission wheel 204 to rotate. The other conveying wheel 203 rotates under the action of friction with the pipeline. The two conveying wheels 203 jointly drive the pipeline to move along the conveying direction. During this process, the tension wheel 206 on the back of the second support frame 200 always abuts against the toothed belt 205 to ensure that the toothed belt is taut and to avoid transmission slippage.

[0037] When the pipeline moves, it drives the fixed wheel 207 of the feeding mechanism to rotate, and the axis of the fixed wheel 207 drives the trigger wheel 213 to rotate synchronously. The counting sensor 214 on the back of the third support frame 202 senses the rotation signal of the trigger wheel 213 in real time (such as the number of tooth triggers) and transmits the signal to the control system. The control system calculates the actual conveying length of the pipeline based on the number of rotations of the trigger wheel 213 and the circumference of the fixed wheel 207. When the conveying length reaches the preset cutting length, the control system sends a signal, the first motor 201 stops running, and the feeding mechanism stops conveying the pipeline.

[0038] High-temperature cutting and end treatment: After the feeding mechanism stops, the heating component 103 (heating rod) of the cutting mechanism is started. The heating component 103 heats the cutting head 102 until the temperature of the cutting head 102 reaches the preset value (set according to the material of the pipe network, for example, the preset temperature of nylon pipe network can be set to 220-260℃, and the preset temperature of metal pipe network can be set to 300-350℃; after the temperature reaches the preset value, the heating component 103 stops heating and maintains the temperature.

[0039] The first cylinder 106 and the second cylinder 108 are activated. The first cylinder 106 pushes the upper heating moving block 101 to move downward along the first slide rail 104, and the second cylinder 108 pushes the lower heating moving block 101 to move upward along the first slide rail 104. The two heating moving blocks 101 drive the cutting heads 102 at the ends to move closer to each other until the two semi-circular cutting edges close together to form a complete circular cutting edge. The circular cutting edge covers the outside of the conduit and cuts the pipe network sleeved on the conduit.

[0040] During the cutting process, the high-temperature cutting head 102 simultaneously melts the cutting position of the pipe network, solidifying the end of the pipe network braided structure and preventing it from loosening. If smoke is generated during the cutting process (such as when cutting nylon pipe networks), the smoke exhaust fan 402 at the lower end of the smoke exhaust channel 401 is activated. The smoke enters the smoke exhaust channel 401 under the suction of the smoke exhaust fan 402 and is discharged from the work area.

[0041] After the cutting is completed, the first cylinder 106 and the second cylinder 108 are reset, which drives the two heating moving blocks 101 and the cutting head 102 to separate from each other, waiting for the next cutting.

[0042] Cutting and threading the cable: Insert one end of the cable to be fitted into the conduit, ensuring that one end of the cable extends out of the conduit; then, pull the cut end of the conduit out from the rear end of the conduit. Since the conduit is pre-fitted outside the conduit, during the pulling process, the end of the conduit naturally covers the end of the cable extending out of the conduit.

[0043] The second motor 304 of the conveying mechanism is started, which drives the power gear 307 to rotate. The power gear 307 drives the transmission gear 306 to rotate through the speed change gear. The transmission gear 306 drives the material threading wheel 303 to rotate through the telescopic universal joint shaft 307. The annular groove on the material threading wheel 303 fits into the conduit, driving the conduit to move slowly. At the same time, the operator can assist in pulling the cable and the conduit together out of the conduit (since the length of the conduit is less than the length of the cable, the conduit always covers the end of the cable during the pulling process), thus completing the operation of threading the cable through the conduit.

[0044] After the pipe threading operation is completed, the second motor 304 stops running, and the feeding mechanism can be restarted to transport and cut the next section of the pipe network. The above process is repeated to achieve continuous processing.

[0045] It should be noted that in this embodiment, the first cylinder 106, the second cylinder 108, the first motor 201, the second motor 304, the counting sensor 214, and the exhaust fan 402 are all electrically connected to an external control system (such as a PLC controller). The control system enables automated and coordinated control of each component, further reducing manual operation and improving overall work efficiency. In addition, the surface of the conveyor wheel 203 can be provided with anti-slip texture to increase friction with the pipeline network, further ensuring the stability of pipeline transportation and preventing slippage.

[0046] It should also be noted that the heating moving block 101 may be equipped with a temperature sensor (such as a PT100 platinum resistance temperature sensor). Both the temperature sensor and the heating component 103 are electrically connected to the external control system. The temperature sensor detects the temperature of the cutting head 102 in real time and transmits the temperature signal to the control system. When the temperature reaches the preset value, the control system controls the heating component 103 to stop heating. When the temperature is lower than the preset lower limit (such as the preset value -5℃), the control system controls the heating component 103 to restart heating, thereby achieving constant temperature control of the cutting head 102 and ensuring stable cutting and end melting effects. The clutch 209 is preferably a pneumatic clutch cylinder or a spring clutch structure: if it is a pneumatic clutch cylinder, its cylinder body is fixed on the third support frame 202, and the end of the piston rod is connected to the second slider 212. When the air is supplied, the piston rod pushes the second slider 212 to move along the second slide rail 211, causing the moving wheel 208 to press against the fixed wheel 207. When the air is cut off, the piston rod resets, and the moving wheel 208 separates from the fixed wheel 207. If it is a spring-type clutch structure, a compression spring is provided between the second slider 212 and the third support frame 202. The spring force causes the moving wheel 208 to press against the fixed wheel 207 under normal conditions. When separation is required, the second slider 212 is pushed by a manual or electric push rod to compress the spring, thereby separating the moving wheel 208 from the fixed wheel 207.

[0047] The aforementioned telescopic universal joint shaft 307 adopts a spline-type telescopic universal joint structure, including a drive shaft, a driven shaft, and a universal joint fork. One end of the drive shaft is connected to the shaft of the transmission gear 306 through the universal joint fork, and the drive shaft has a spline groove inside. One end of the driven shaft is connected to the shaft of the feed wheel 303 through the universal joint fork, and the other end of the driven shaft has a spline that matches the spline groove. The spline end of the driven shaft is inserted into the spline groove of the drive shaft and can slide along the axial direction of the spline groove (to achieve telescopic movement). At the same time, torque is transmitted through spline engagement to ensure that power can still be stably transmitted when the feed wheel 303 slides along the third slide rail 302.

[0048] The aforementioned conduit is made of metal (such as stainless steel) or high-strength engineering plastic. Its outer diameter is matched with the inner diameter of the circular blade of the cutter head 102 after it is closed (gap ≤ 0.5mm), and its length is greater than the distance from the feeding mechanism to the conveying mechanism. The positioning of the conduit is achieved by the feeding wheel 303 of the conveying mechanism and the cutter head 102 of the cutting mechanism together. The annular groove of the feeding wheel 303 positions the conduit radially, and the circular blade of the cutter head 102 positions the end of the conduit when it is closed, ensuring that the conduit does not shift during operation and ensuring the accuracy of pipe network installation and cutting.

[0049] Furthermore, the air supply for all the aforementioned cylinders (first cylinder 106, second cylinder 108, and clutch cylinder) comes from an external air compressor, and solenoid valves are installed in the air lines. These solenoid valves are electrically connected to the control system to achieve automated control of the cylinders. Both the first motor 201 and the second motor 304 are servo motors, which enable precise control of speed and direction, further improving the accuracy of pipeline delivery and conduit delivery. The slide rails (first slide rail 104, second slide rail 211, and third slide rail 302) can all be linear guides. Linear guides feature high precision and low friction, ensuring the smoothness and accuracy of the slider movement.
