Description

Technical Field

[0001] This utility model relates to the field of wire and cable production technology, and in particular to a cutting device for the production and manufacturing of cables and wires. Background Technology

[0002] As essential wire products for transmitting electrical energy, information, and realizing electromagnetic energy conversion, wires and cables play an indispensable role in modern industry and daily life. In a broad sense, wires and cables encompass various insulated and non-insulated wires, while in a narrow sense, cables specifically refer to insulated cables, which are assemblies consisting of one or more insulated cores and possibly a covering layer, a total protective layer, and an outer sheath, sometimes also containing additional non-insulated conductors.

[0003] During cable production, finished cables are typically wound onto a take-up spool for storage. Once a roll of cable reaches the predetermined winding length, it needs to be cut to begin winding the next roll. However, modern cable production lines often operate continuously, which places higher demands on cable cutting equipment, requiring a device capable of efficiently and accurately cutting cables in a continuous production environment.

[0004] Currently, existing cable cutting methods and equipment are insufficient to fully meet the demands of continuous production. Some traditional cutting methods may require manual intervention, which is inefficient and poses safety hazards; while other highly automated cutting equipment is often complex in structure and bulky, making it difficult to integrate into compact production lines, or ensuring cutting accuracy and stability during high-speed continuous production. Furthermore, frequent start-up and shutdown operations also affect production efficiency and equipment lifespan. To address these issues, existing technologies urgently need improvement. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cutting device for cable and wire manufacturing.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cutting device for cable and wire manufacturing, including a frame, and further comprising:

[0007] The clamping roller and the cutting roller are rotatably mounted on the frame;

[0008] A drive assembly for driving the cutting roller and the clamping roller to rotate synchronously in opposite directions to clamp and convey the cable;

[0009] A cutter assembly is disposed inside a cutting roller. The cutter assembly includes a cutter that can slide out and retract in the radial direction of the cutting roller, and a cutter drive mechanism for driving the cutter to extend and retract.

[0010] The outer periphery of the clamping roller is provided with a cutting sleeve that cooperates with the cutter to cut the cable.

[0011] More specifically, the cutter drive mechanism includes:

[0012] A drive rod is located inside the cutting roller along its axial direction;

[0013] The drive block is fixedly connected to the bottom of the cutter;

[0014] A tapered block fixedly mounted on the drive rod for pushing the drive block to extend the cutter;

[0015] And an electric push rod for driving the drive rod to move axially.

[0016] Furthermore, the cutter drive mechanism also includes a tapered sleeve fixedly sleeved on the drive rod. The tapered sleeve has a tapered inner wall and is used to abut against the drive block when the electric push rod retracts, so as to drive the cutter to retract.

[0017] Preferably, the driving component includes:

[0018] The drive motor is fixedly mounted on the side wall of the frame, and the output shaft of the drive motor passes through the frame and is fixedly connected to the cutting roller.

[0019] The first pulley connected to the cutting roller;

[0020] The second pulley connected to the clamping roller;

[0021] And a belt wound in a figure-eight shape around the first and second pulleys.

[0022] To ensure belt tension, the drive assembly also includes a belt tensioning mechanism mounted on the frame, which includes an auxiliary pulley that rests against the belt.

[0023] More specifically, the belt tensioning mechanism also includes:

[0024] The opening is tightened and penetrates through the side wall of the frame.

[0025] The slider is connected to the auxiliary wheel and is slidably connected to the inner wall of the tensioning port;

[0026] A compression spring is fixedly connected between the inner wall of the tensioning port and the slider.

[0027] To improve the stability of cable delivery, the cutting device also includes:

[0028] An auxiliary roller that is rotatably mounted on the frame;

[0029] And a pressure roller that can be floated up and down on the frame, the pressure roller being located between the auxiliary roller and the clamping roller, used to press the cable.

[0030] To accommodate cables of different diameters, the cutting device also includes an adjustment assembly, which includes:

[0031] Two clearance openings are symmetrically opened on the side wall of the frame. A circular sleeve is vertically slidably connected in each clearance opening, and the two ends of the clamping roller are rotatably connected to the two circular sleeves respectively.

[0032] Two adjusting screws are threaded to the frame, and the lower ends of the two adjusting screws are rotatably connected to two clamping rollers respectively, which are used to adjust the height position of the clamping rollers.

[0033] Preferably, the edges of the belt are edged with metal.

[0034] To extend the service life of the cutting sleeve, it is made of a non-metallic material that is impact-resistant and has a certain degree of toughness.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] By integrating a cutter controlled by a cutter drive mechanism inside the cutting roller used for cable conveying, and cooperating with the cutting sleeve on the clamping roller, a rapid cutting operation can be completed without stopping the production line during continuous cable conveying. This design cleverly combines conveying and cutting functions on the same pair of rollers, resulting in a compact structure and precise operation. It fundamentally solves the problem of low efficiency in existing cable cutting methods mentioned in the background art, significantly improving the efficiency and automation level of cable production. Compared with existing technologies, the cutting device of this invention not only adapts to the needs of continuous production but also has a simple and reliable structure, is easy to integrate into existing production lines, and has significant economic benefits and practical value.

Detailed Implementation

[0043] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0044] In the field of wire and cable manufacturing, with the increasing demand for automation and continuous production, how to efficiently and accurately complete the cutting operation during the continuous output of cables from production equipment and winding onto the take-up reel has become an urgent technical problem. Traditional cutting methods often require stopping the production line or using complex and bulky independent cutting equipment, which not only affects production efficiency but also increases the space occupied by the equipment and costs. For example, after the cable is wound up, it needs to be cut off from the production line to replace the take-up reel. If the cutting cannot be completed while the cable is in motion, the entire production line must be stopped, and restarted only after the cutting is completed. This intermittent operation mode significantly reduces overall production efficiency. To overcome these limitations of existing technologies, this utility model proposes an innovative cutting device for cable and wire manufacturing. This device can be integrated into a continuous production line to complete the cutting during the cable's movement, thereby greatly improving production efficiency. The technical solution of this utility model achieves rapid and accurate cutting in a continuous production environment by cleverly integrating the cutting function into the roller used to transport the cable.

[0045] like Figures 1 to 5 The cable and wire cutting device shown includes a frame 1, and further includes:

[0046] The clamping roller 4 and the cutting roller 5 are rotatably mounted on the frame 1;

[0047] A drive assembly is used to drive the cutting roller 5 and the clamping roller 4 to rotate synchronously in opposite directions to clamp and convey the cable;

[0048] The cutter assembly is located inside the cutting roller 5. The cutter assembly includes a cutter 19 that can slide out and retract in the radial direction of the cutting roller 5, and a cutter drive mechanism for driving the cutter 19 to extend and retract.

[0049] The outer periphery of the clamping roller 4 is provided with a cutting sleeve 15 that cooperates with the cutter 19 to cut the cable.

[0050] Compared to existing technologies that require stopping the production line or using separate cutting equipment, the cutting device of this invention has significant advantages. Existing technologies often require additional space and complex synchronization control systems when cutting on continuous production lines, or necessitate sacrificing production efficiency. This invention, by integrating the cutting function into the conveyor rollers, has a more compact structure and can be directly installed on the production line without requiring additional space. More importantly, since the cutting action occurs while the cable is being clamped and conveyed by the clamping rollers 4 and 5, the cutting can be completed while the cable is in motion, without stopping the production line, which greatly improves production efficiency. Furthermore, cutting the cable while it is clamped also helps ensure the accuracy of the cutting position and the quality of the cut.

[0051] When using the cable cutting device of this invention, the device is first installed between the cable production equipment and the winding equipment. After the cable is output from the production equipment, it passes above the auxiliary roller 2 (if an auxiliary roller 2 is provided), then below the pressure roller 3 (if a pressure roller 3 is provided), and then enters between the clamping roller 4 and the cutting roller 5. The drive assembly operates, driving the cutting roller 5 to rotate, and through the transmission mechanism (e.g., belt 9, first pulley 7, second pulley 8), driving the clamping roller 4 to rotate synchronously in the opposite direction. The clamping roller 4 and the cutting roller 5 clamp and transport the cable forward. When a roll of cable is wound up and needs to be cut, the cutter drive mechanism is controlled to operate. For example, if the cutter drive mechanism is a combination of an electric push rod 10, a drive rod 11, a conical block 14, and a drive block 13 (see...), the cable cutting mechanism is a combination of an electric push rod 10, a drive rod 11, a conical block 14, and a drive block 13. Figure 4 When the electric push rod 10 extends, it drives the drive rod 11 to move axially along the cutting roller 5. The conical block 14 on the drive rod 11 abuts against the drive block 13 connected to the cutter 19. The inclined surface of the conical block 14 converts the axial thrust into the radial movement of the drive block 13, thereby driving the cutter 19 to extend radially from the cutter groove of the cutting roller 5. The extended cutter 19 cuts through the cable and abuts against the cutting sleeve 15 on the outer periphery of the clamping roller 4, completing the cable cutting. After cutting, the cutter drive mechanism reverses its action. For example, the electric push rod 10 retracts, driving the drive rod 11 to move in the opposite direction. The drive block 13 is pulled back by the conical sleeve 12 (if a conical sleeve 12 is provided) or by other reset mechanisms, thereby driving the cutter 19 to retract into the cutting roller 5. The entire cutting process is completed while the cable is continuously being conveyed, without stopping the machine. The clamping roller 4 and the cutting roller 5 continue to rotate, feeding out a further section of the cut cable for subsequent operations.

[0052] In this process, frame 1 provides stable support. The synchronous counter-rotation of clamping roller 4 and cutting roller 5 is the basis for continuous conveying and cutting. The drive assembly provides the necessary power and transmission. The cutting assembly is the core of the cutting process; the cutter 19 is the actual cutting tool, while the cutting drive mechanism ensures precise extension and retraction control of the cutter 19. The cutting sleeve 15 provides the necessary support and protection for cutting. Through the coordinated work of these components, this invention achieves efficient and automated cutting in the continuous cable production process.

[0053] As one embodiment of this utility model, the cutter driving mechanism includes:

[0054] A drive rod 11 is disposed inside the cutting roller 5 along the axial direction;

[0055] The drive block 13 is fixedly connected to the bottom of the cutter 19;

[0056] A conical block 14 is fixedly sleeved on the drive rod 11 to push the drive block 13 so that the cutter 19 extends;

[0057] And an electric push rod 10 for driving the drive rod 11 to move axially.

[0058] In implementation, the drive rod 11 is a slender rod-shaped component that extends along the axial direction of the cutting roller 5 and is located inside the cutting roller 5. The drive rod 11 can be made of metal or high-strength engineering plastic, possessing sufficient rigidity and strength to withstand the thrust generated by the cutter drive mechanism during operation. The drive block 13 is fixedly connected to the cutter 19 and is used to convert the axial movement of the drive rod 11 into the radial movement of the cutter 19. The drive block 13 can be a block-shaped structure with an inclined surface, which engages with the conical block 14. When the conical block 14 pushes the drive block 13, the drive block 13 slides along the radial direction of the cutting roller 5, thereby causing the cutter 19 to extend. The conical block 14 is fixedly sleeved on the drive rod 11 and located on one side of the drive block 13. The inclined surface of the conical block 14 corresponds to the inclined surface of the drive block 13. When the drive rod 11 moves axially, the conical block 14 pushes the drive block 13, causing it to slide along the radial direction of the cutting roller 5. The electric actuator 10 is used to drive the drive rod 11 to move axially. The electric actuator 10 can be a linear motor or a lead screw mechanism driven by a motor, which can provide sufficient thrust to overcome the resistance encountered by the cutter 19 when cutting the cable.

[0059] As one embodiment of the present invention, the cutter drive mechanism further includes a conical sleeve 12 fixedly sleeved on the drive rod 11. The conical sleeve 12 has a conical inner wall and is used to abut against the drive block 13 when the electric push rod 10 retracts, so as to drive the cutter 19 to retract.

[0060] In practice, the conical sleeve 12 is a hollow sleeve-shaped component that is fixedly fitted onto the drive rod 11 and located behind the conical block 14 (relative to the extension direction of the cutter 19). The inner wall of the conical sleeve 12 is conical, and the diameter of its conical inner wall gradually decreases from the front end to the rear end. The outer surface of the drive block 13 corresponds to the conical inner wall of the conical sleeve 12. When the electric push rod 10 extends, the conical block 14 pushes the drive block 13, causing the cutter 19 to extend; when the electric push rod 10 retracts, the conical inner wall of the conical sleeve 12 abuts against the outer surface of the drive block 13 and pushes the drive block 13 to move backward, thereby causing the cutter 19 to retract.

[0061] Therefore, the tapered sleeve 12 provides an active and rapid retraction mechanism for the cutter 19. This ensures that the cutter 19 can quickly leave the working position after cutting, avoiding interference or scratching of subsequent cables and improving the efficiency and safety of the entire cutting cycle. Compared with relying solely on the tension of the spring or the cable itself to retract the cutter 19, the tapered sleeve 12 can more reliably guarantee the retraction of the cutter 19. Especially in high-speed continuous production, this active retraction mechanism can significantly improve the stability and reliability of the equipment.

[0062] As one embodiment of this utility model, the driving component includes:

[0063] The drive motor 6 is fixedly installed on the side wall of the frame 1, and the output shaft of the drive motor 6 passes through the frame 1 and is fixedly connected to the cutting roller 5;

[0064] The first pulley 7 is connected to the cutting roller 5;

[0065] The second pulley 8 is connected to the clamping roller 4;

[0066] And a belt 9 wound in a figure-eight shape around the first pulley 7 and the second pulley 8.

[0067] In practice, the first pulley 7 and the second pulley 8 are fixed to the shafts of the cutting roller 5 and the clamping roller 4, respectively, and rotate synchronously with them. The belt 9 is wound around the first pulley 7 and the second pulley 8 in a special figure-eight pattern. This figure-eight winding pattern ensures that the first pulley 7 and the second pulley 8 rotate in opposite directions, thereby guaranteeing that the clamping roller 4 and the cutting roller 5 can rotate synchronously in opposite directions to clamp and transport the cable.

[0068] As one embodiment of the present invention, the drive assembly also includes a belt tensioning mechanism disposed on the frame 1, the belt tensioning mechanism including an auxiliary wheel 21 abutting against the belt 9.

[0069] In practice, the auxiliary wheel 21 is a rotatable wheel mounted on the frame 1 via a support structure, located inside or outside the belt 9, and in contact with the belt 9. The position of the auxiliary wheel 21 can be adjusted to change its contact position and pressure with the belt 9. By adjusting the position of the auxiliary wheel 21, the tension of the belt 9 can be changed to keep it within a suitable range.

[0070] As one embodiment of this utility model, the belt tensioning mechanism further includes:

[0071] A tensioning opening is provided, which is opened through the side wall of the frame 1 and connected to the auxiliary wheel 21. The slider 16 is slidably connected to the inner wall of the tensioning opening.

[0072] The compression spring 17 is fixedly connected between the inner wall of the tensioning port and the slider 16.

[0073] During implementation, the compression spring 17 provides a continuous and buffering elastic force to the slider 16 and the auxiliary wheel 21, realizing automatic compensation and adjustment of the tension of the belt 9. It can adapt to small changes during operation, making the tension effect more stable and longer-lasting.

[0074] As one embodiment of this utility model, it also includes:

[0075] An auxiliary roller 2 is rotatably mounted on the frame 1;

[0076] And a pressure roller 3 that can be floated up and down on the frame 1, the pressure roller 3 being located between the auxiliary roller 2 and the clamping roller 4, used to press the cable.

[0077] In practice, the auxiliary roller 2 is positioned before the cable enters the clamping roller 4 and the cutting roller 5 to guide the cable's movement and reduce bending and twisting. The pressure roller 3 is located between the auxiliary roller 2 and the clamping roller 4. It can float up and down and uses its own weight or spring pressure to press the cable firmly against the clamping roller 4. The floating design of the pressure roller 3 allows it to accommodate cables of different diameters while maintaining a firm clamping force on the cable.

[0078] Therefore, the auxiliary roller 2 and pressure roller 3 guide and tension the cable before it enters the cutting area. This effectively eliminates cable vibration, maintains the cable's straightness and stable tension, improves the smoothness of transport, and provides better initial conditions for subsequent cutting processes, thus ensuring the accuracy of the cutting position and the quality of the cut. Compared with solutions without auxiliary roller 2 and pressure roller 3, the cable transport process of this invention is more stable and reliable, reducing cable damage and cutting errors.

[0079] As one embodiment of this utility model, it also includes an adjustment component, which includes:

[0080] Two clearance openings are symmetrically opened on the side wall of the frame 1. A circular sleeve 20 is vertically slidably connected in each clearance opening. The two ends of the clamping roller 4 are rotatably connected to the two circular sleeves 20 respectively.

[0081] Two adjusting screws 18 are threadedly connected to the frame 1. The lower ends of the two adjusting screws 18 are rotatably connected to the two clamping rollers 4 respectively, and are used to adjust the height position of the clamping rollers 4.

[0082] In implementation, the clearance openings are two holes formed on the side wall of the frame 1, which provide movement space for the circular sleeve 20. The circular sleeve 20 is fitted onto both ends of the clamping roller 4 and can slide vertically within the clearance openings. The adjusting screw 18 is threadedly connected to the frame 1, and its lower end is rotatably connected to the circular sleeve 20. By rotating the adjusting screw 18, the height position of the circular sleeve 20 can be changed, thereby adjusting the height position of the clamping roller 4. Thus, by rotating the adjusting screw 18, the distance between the clamping roller 4 and the cutting roller 5 can be easily adjusted, allowing the device to adapt to cables of different diameters, enhancing the versatility and applicability of the equipment, and also facilitating compensation for gap changes caused by roller wear.

[0083] As one embodiment of this utility model, the edge of the belt 9 is provided with a metal edging.

[0084] In practice, metal edging refers to applying a layer of metal material, such as steel, aluminum, or copper, to the edge of the belt 9. The metal edging can be fixed to the belt 9 by bonding, riveting, or welding. The purpose of the metal edging is to improve the wear resistance and tensile strength of the belt 9, thereby extending its service life.

[0085] Therefore, due to the figure-eight design of the belt, friction occurs at the intersections. The addition of a metal edging significantly reduces the coefficient of friction in the intersection areas and improves wear resistance, thereby greatly extending the belt's service life and reducing maintenance costs. Compared to belts without metal edging, the belt 9 of this invention has higher durability and reliability, and is better suited for long-term operation and high-load conditions.

[0086] As one embodiment of this utility model, the cutting sleeve 15 is made of a non-metallic material that is impact-resistant and has a certain degree of toughness.

[0087] In practice, the cutting sleeve 15 can be made of non-metallic materials such as polyurethane, nylon, rubber, or Teflon. These materials have good impact resistance and toughness, providing a reliable support surface when the cutter 19 cuts the cable and reducing wear on the cutting edge of the cutter 19.

[0088] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection claimed by this utility model, which is defined by the appended claims and their equivalents.
