Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a cutting device for producing high flame-retardant and wear-resistant power cables. Background Technology

[0002] With rapid economic development and the continuous advancement of industrialization and urbanization, electricity demand continues to grow. As a key carrier for power transmission and distribution, power cables are finding increasingly wider applications, including urban underground power grids, power plant lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. High flame-retardant and wear-resistant power cables, due to their excellent fire resistance and wear resistance, effectively ensure the safety and stability of power transmission, and are increasingly in demand in special environments such as high-rise buildings, subways, and mines, as well as in locations with high safety requirements.

[0003] Chinese Patent No. CN217290217U discloses a cable cutting device, including a base, a protective cover, and a grinding motor. The protective cover is located on one side of the base, and the grinding motor is located on the side of the protective cover away from the base. A grinding disc is located on the side of the grinding motor close to the base. A support frame is located on the upper side of the base, and a cutting groove is located at the center of the upper part of the support frame. A cutting blade is located inside the cutting groove, and flat nozzles are symmetrically arranged below the cutting groove. A cutting slot is located directly below the cutting groove, and a cable pad is located on one side of the cutting slot. An electric push rod is located above the grinding motor.

[0004] The above technical solution has the following drawbacks: Although cable pads are installed in the device to support the cable during the cutting process, the stability of the cable during transportation may still be affected to some extent. Especially during high-speed transportation or when the cable length is long, the cable may shift due to its own weight or external forces, thus affecting the accuracy of the cutting.

[0005] To address these issues, we propose a high flame-retardant and wear-resistant power cable production and cutting device. Utility Model Content

[0006] The purpose of this invention is to provide a high flame-retardant and wear-resistant power cable production and cutting device to solve the problems of insufficient cable transmission stability and inability to maintain centering mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high flame-retardant and wear-resistant power cable production and cutting device, comprising a base plate and a feeding structure and a winding structure disposed above the base plate, wherein the feeding structure is fixedly connected to the left side of the upper surface of the base plate, the winding structure is fixedly connected to the right side of the upper surface of the base plate, and a cutting structure is disposed between the feeding structure and the winding structure.

[0008] The cutting structure includes a cable limiting unit and a cable cutting unit;

[0009] The cable limiting unit includes a groove, a first slide, a second slide, a connecting rod, a first motor, a second threaded rod, a second nut, a sliding rod, a slider, a column, a support frame, and rollers. The groove and the first slide are respectively opened on the left side of the upper surface of the base plate. There are two second slides respectively opened on the right side of the upper surface of the base plate. The second threaded rod is set inside the groove. The output end of the first motor is connected to the second threaded rod through a coupling. The sliding rods are respectively set inside the first slide and the second slide. There are two second nuts respectively threadedly connected to the second threaded rod. The sliders are connected in pairs (three groups in total) to the sliding rods inside the first and second slides. The bottom of the column is fixedly connected to the upper surface of the nut and the slider. The support frame is fixedly connected to the side of the column that is close to each other. The middle of the roller is rotatably connected to the middle of the support frame. A connecting rod connects the columns. The connecting rod is respectively connected between the columns inside the first slide and the second slide.

[0010] Preferably, the threads at both ends of the threaded rod are opposite. When the motor drives the threaded rod to rotate, the two nuts move simultaneously in opposite directions. This design simplifies the structure and allows the cable limiting unit to adjust the positions of the rollers on both sides simultaneously, ensuring that the cable remains centered during transport and improving cutting accuracy.

[0011] Preferably, the cable cutting unit includes a fixed frame, a bidirectional electric push rod, a connecting block, and a cutting blade. The fixed frames are arranged in pairs between slide groove one and slide groove two. The sides of the fixed frames that are close to each other have placement slots. The bidirectional electric push rod is disposed inside the placement slot. The connecting block is connected to the output end of the bidirectional electric push rod. The two ends of the cutting blade are connected to the connecting block, so that the cutting blade can achieve fast and stable cutting action through the drive of the bidirectional electric push rod.

[0012] Preferably, a drive structure is fixedly connected to the outside of the winding structure. The drive structure is driven by a motor and a pulley, which can ensure that the winding structure rotates smoothly and quickly, thereby effectively winding up the cut cable.

[0013] Preferably, the winding structure has a cable management structure on the left side. The cable management structure includes a support rod, a second motor, a first threaded rod, a first nut, and a connecting ring. The support rods are fixedly connected in pairs to the front and rear sides of the upper surface of the base plate. The first threaded rod is connected at both ends between the two support rods. The first nut is threadedly connected to the first threaded rod. The second motor is connected to the first threaded rod through a coupling. The bottom of the connecting ring is fixedly connected to the upper surface of the first nut. The design of the cable management structure allows the cable to be neatly arranged before winding, avoiding cable crossing and tangling.

[0014] Preferably, the bidirectional electric push rod is electrically connected to the control system. Through the precise control of the bidirectional electric push rod by the control system, the cutting action can be automated.

[0015] Preferably, the cutting blades are made of high-strength, high-hardness alloy steel. The two cutting blades have opposite blades, and the high-strength, high-hardness alloy steel material ensures that the cutting blades have sufficient wear resistance and edge retention, maintaining a sharp cutting effect for a long time. At the same time, the opposite blade design of the two cutting blades makes the cutting process smoother and more efficient, helping to improve cutting quality and production efficiency.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This high flame-retardant and wear-resistant power cable production and cutting device, through the structure of opposite threads at both ends of the threaded rod and the drive of the motor, realizes the synchronous adjustment of the positions of the left and right rollers of the cable limiting unit. This not only simplifies the complex adjustment mechanism in the traditional structure, but also improves the stability and centering accuracy during cable transportation, thereby ensuring the precision of cutting.

[0018] 2. This high flame-retardant and wear-resistant power cable production and cutting device uses a motor-driven belt pulley transmission for its winding structure, ensuring a smooth and rapid winding process. Simultaneously, the cable management structure design allows the cables to be neatly arranged before winding, avoiding cable crossing and tangling, thus improving winding efficiency and cable protection.

[0025] Example 1:

[0026] When transmitting at high speeds or with long cables, the cable may shift due to its own weight or external forces, affecting the accuracy of the cutting. To resolve this issue, please refer to [link to relevant documentation]. Figures 1-4 This utility model provides a technical solution: a high flame-retardant and wear-resistant power cable production and cutting device, including a base plate 1 and a feeding structure 2 and a winding structure 4 disposed above the base plate 1.

Two slides 103 are respectively located on the right side of the upper surface of the base plate 1. The second threaded rod 502 is located inside the groove 101, and the threads at both ends of the second threaded rod 502 are opposite. The output end of the first motor 501 is connected to the second threaded rod 502 via a coupling, providing power to the second threaded rod 502 and enabling rapid adjustment of the position of the roller 508. Slide rods 504 are respectively installed inside slide groove 102 and slide groove 2 103. Nut 2 503 has two threads respectively connected to threaded rod 2 502. Through the opposite threads at both ends, the two nuts 2 503 can move in opposite directions simultaneously, thereby adjusting the position of roller 508. Sliders 505 are connected in pairs, for a total of three groups, to slide rods 504 inside slide groove 102 and slide groove 2 103, providing support and guidance for sliders 505 and ensuring that sliders 505 can slide smoothly. The bottom of column 506 is fixedly connected to the upper surface of nut and slider 505, supporting support frame 507 and roller 508, ensuring that roller 508 can stably clamp the cable. Support frame 507 is fixedly connected to the adjacent sides of column 506, providing installation and support for roller 508 and ensuring that roller 508 can rotate freely. The middle part of roller 508 is rotatably connected to the middle part of support frame 507, clamping and guiding the cable through the cutting area, ensuring that the cable remains stable during the cutting process. A connecting rod is connected between the columns 506, and the connecting rod 104 is connected between the columns 506 inside the first slide 102 and the second slide 103 respectively.

[0029] Example 2:

[0030] To address the efficiency and accuracy issues in cable cutting, winding, and cable management, based on Embodiment 1, the cable cutting unit includes a fixing frame 6, a bidirectional electric push rod 601, a connecting block 602, and a cutting blade 603. The fixing frames 6 are arranged in pairs between slide groove one 102 and slide groove two 103, providing installation and support for the bidirectional electric push rod 601 and the cutting blade 603. A placement groove is formed on the side of the fixing frames 6 that is close to each other. The bidirectional electric push rod 601 is placed inside the placement groove and achieves rapid and precise telescopic movement through a control system, driving the cutting blade 603 to perform cutting. The connecting block 602 is connected to the output end of the bidirectional electric push rod 601, and both ends of the cutting blade 603 are connected to the connecting block 602. The bidirectional electric push rod 601 is electrically connected to the control system. The cutting blade 603 is made of high-strength, high-hardness alloy steel, and the blades of the two cutting blades 603 face each other.

[0031] A drive structure 7 is fixedly connected to the outer side of the winding structure 4. The drive structure 7 is driven by a motor and pulley, providing a stable power source for the winding structure 4 and ensuring that the cable can be wound smoothly and quickly. A cable management structure is located on the left side of the winding structure 4. The cable management structure includes support rods 3, a second motor 301, a first threaded rod 302, a first nut 303, and a connecting ring 304. The support rods 3 are fixedly connected in pairs to the front and rear sides of the upper surface of the base plate 1, providing installation and support for the first threaded rod 302 and the second motor 301. The first threaded rod 302 is connected at both ends between the two support rods 3, and the first nut 303 is threadedly connected to the first threaded rod 302, converting the rotational motion of the motor into linear motion, driving the connecting ring 304 to move. The second motor 301 is connected to the first threaded rod 302 via a coupling, and the bottom of the connecting ring 304 is fixedly connected to the upper surface of the first nut 303 to restrict the cable. Its left and right movement achieves the cable management function, preventing cable crossing and tangling.

[0032] Working Principle: The power cable to be cut is placed on the feeding structure 2. Motor 501 is started, and the position of roller 508 is adjusted to allow the cable to pass smoothly through the cutting area. When motor 501 starts, it drives threaded rod 502 to rotate via a coupling. Because the threads at both ends of threaded rod 502 are opposite, the two nuts 503 move simultaneously in opposite directions. The movement of nuts 503 causes slider 505 to slide on slide bar 504, which in turn pushes roller 508 on column 506 and support frame 507 to adjust their positions. Roller 508 clamps and guides the cable through the cutting area, ensuring the cable remains stable during the cutting process.

[0033] The bidirectional electric actuator 601 extends and retracts according to the instructions of the control system. The extension and retraction of the bidirectional electric actuator 601 drives the connecting block 602 and the cutting blade 603 to move. When the two cutting blades 603 move relative to each other, they clamp and cut the cable passing between them.

[0034] The motor 301 of the cable management structure drives the threaded rod 302 to rotate, causing the nut 303 and the connecting ring 304 to move. The movement of the connecting ring 304 restricts the position of the cable, realizing the cable management function and preventing the cable from crossing and tangling. The drive structure 7 of the winding structure is driven by a motor and belt pulley, providing a stable power source for the winding structure.
