Description

Technical Field

[0001] This invention relates to the field of pipe cutting technology, specifically to a cable protection sleeve pipe cutting and conveying system. Background Technology

[0002] Cable protection pipes are widely used in power, telecommunications and other fields to provide physical protection for cables during cable laying, preventing damage from external forces and environmental corrosion. With the widespread use of new pipe materials such as fiberglass, PVC, and MPP, higher requirements have been placed on the cutting and processing of cable protection pipes, especially in terms of cutting efficiency, cross-sectional quality, and adaptability to different pipe materials.

[0003] In the prior art, the applicant's earlier invention patent application (publication number CN119141631A) discloses a cable protection pipe cutting machine and cutting method. This cutting machine includes a cutting box, a feeding device, and circumferential clamps. By setting a first circumferential clamp and a second circumferential clamp, the protective pipe is clamped synchronously, effectively correcting pipe bending and ensuring the flatness of the cut end face. Its cutting mechanism integrates a saw blade and a cutting knife, which can be switched according to the material of the protective pipe, achieving adaptability to cutting pipes of different materials. Simultaneously, the equipment automatically measures the pipe diameter through a clamping plate assembly and adjusts the height of the cutting box using a lifting assembly to ensure that the cutting axis coincides with the pipe axis, demonstrating a high level of automation.

[0004] However, the aforementioned prior patents still have the following shortcomings in practical applications: First, the cutting machine only focuses on the cutting process itself and does not involve the automatic acceptance and transfer of the cut pipe fittings. The cut material segments need to be unloaded manually or by auxiliary equipment, which affects the overall production efficiency. Second, its cutting mechanism integrates the saw blade and cutting knife on the same side and switches through a complex locking mechanism, which is relatively complex. Moreover, the counterweight mechanism and the cutting mechanism share the same rotating platform, and the vibrations generated during cutting are prone to mutual interference, affecting the cutting stability. Third, for the cutting of pipe fittings of different lengths (especially short and long materials), the existing equipment lacks flexible and rapid material receiving and adaptation capabilities. Switching specifications requires a lot of adjustment time, which is difficult to meet the needs of flexible production. Summary of the Invention

[0005] The purpose of this invention is to provide a cable protection sleeve fitting cutting and conveying system to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable protection sleeve fitting cutting and conveying system, comprising: The feeding device, cutting device, and receiving device are arranged sequentially along the conveying direction of the protective pipe; The cutting device includes a mounting frame and a housing mounted on the mounting frame. The housing is equipped with a cutting mechanism that can rotate around the axis of the protective tube. The cutting mechanism includes a first cutter and a second cutter arranged opposite to each other, as well as a first sliding mechanism and a second sliding mechanism that drive the first cutter and the second cutter to feed independently along the radial direction of the protective tube. The receiving device includes a platform that can move along the axis of the protective tube, a receiving box that is rotatably mounted on the platform, and a plurality of clamping fixtures mounted on the periphery of the receiving box. The receiving box can be rotated to align different clamping fixtures with the output end of the cutting device.

[0007] Preferably, the feeding device includes: frame; A sliding plate slidably mounted on the frame; A rack mounted on the frame and extending along the axis of the protective tube; A drive gear mounted on the sliding plate and meshing with the rack, and a servo motor that drives the drive gear to rotate; A clamping plate assembly mounted on the sliding plate, the clamping plate assembly including two opposing clamping plates and positive and negative lead screws that drive the two clamping plates to move closer or further apart synchronously.

[0008] Preferably, the cutting device further includes a counterweight mechanism, which is installed independently of the housing on the mounting frame and located on the outside of the housing, for pressing the protective tube from above during cutting.

[0009] Preferably, the counterweight mechanism includes a lifting cylinder and a counterweight block connected to the lifting cylinder.

[0010] Preferably, the first cutting tool is a cold cutting tool, and the second cutting tool is a power cutting tool; the cutting mechanism further includes an upper cutting tool holder connected to the first sliding mechanism and a lower cutting tool holder connected to the second sliding mechanism, the cold cutting tool is mounted on the upper cutting tool holder, and the power cutting tool is mounted on the lower cutting tool holder.

[0011] Preferably, the receiving device further includes a linear slide rail disposed below the platform and a servo drive unit for driving the platform to slide along the linear slide rail.

[0012] Preferably, the bottom of the receiving box is provided with a rotating seat, which is rotatably connected to the platform via a rotating bearing; the receiving device also includes a motor for driving the rotating seat to rotate, and a lifting servo cylinder for driving the receiving box to move vertically up and down on the rotating seat.

[0013] Preferably, the plurality of clamping fixtures include at least one chuck fixture for clamping short materials and one opposing clamping plate fixture for clamping long materials.

[0014] Preferably, the opposing clamping plate fixture includes: Two movable clamps positioned opposite each other; Two racks are respectively connected to the two movable clamping plates; A central gear that meshes with both of the aforementioned racks; And a motor that drives the central gear to rotate.

[0015] Preferably, the opposing clamping plate fixture further includes a telescopic roller, which is slidably connected to the receiving box via a telescopic plate and driven by a telescopic cylinder to adjust its extension distance relative to the moving clamping plate.

[0016] Compared with existing technologies, this invention achieves automatic receiving and transfer of cut pipe fittings by setting a receiving device at the output end of the cutting device, solving the problem of manual unloading required by existing equipment and significantly improving production efficiency. The receiving device adopts a movable and rotatable receiving box structure, with multiple clamping fixtures of different specifications configured on its peripheral walls. Rotation allows for rapid switching between different clamping methods and pipe diameter specifications, especially adapting to different receiving needs for short and long materials, greatly enhancing the equipment's flexible production capabilities. Simultaneously, the two cutting tools in the cutting device are arranged facing each other and driven independently, simplifying the tool switching structure and avoiding mutual interference; the counterweight mechanism is installed independently of the cutting box, effectively isolating cutting vibration and further improving the stability of the cutting process and the quality of the cross-section.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 7 As shown, the present invention provides a specific embodiment of a cable protection sleeve fitting cutting and conveying system.

[0020] The main concept of this invention is to improve the adaptability of equipment during the cutting of cable protection sleeves, especially the ability to switch between cutting short and long materials. In existing technologies, such as the applicant's prior patent application (publication number CN119141631A, disclosing a cable protection sleeve cutting machine and cutting method, hereinafter referred to as the prior patent), a cutting box and a feeding device are described. However, these technologies still suffer from low conversion efficiency and insufficient adaptability when dealing with cutting pipes of different lengths and diameters. Based on this, this invention proposes adding a receiving device 3, which is configured at the output end of the cutting box, i.e., the feeding device 1, cutting device 2, and receiving device 3 are sequentially arranged along the conveying direction of the protective pipe. The function of the receiving device 3 is to receive and transfer the cut protective pipe. Through modular structural design and flexible adjustment capabilities, it achieves rapid switching from long to short materials and from one clamping method to another, significantly improving the overall utilization rate of the equipment.

[0021] For ease of understanding, the relevant structural features of this invention are described sequentially along the feeding direction of the protective tube, as follows: The structure of the feed device 1 is referenced. Figure 1 As shown, its overall structure is basically the same as the feeding device in the prior patent, but it has been optimized for stability control and motion accuracy. It includes two second linear guide rails 16 fixedly mounted on the frame 11, with a sliding plate 19 slidably mounted on each rail. It also includes a rack arranged along the axis of the protective tube. A servo motor is fixedly mounted on the sliding plate 19, and a drive gear is fixedly mounted on the output shaft of the servo motor. The drive gear meshes with the rack, allowing the sliding plate 19 to slide back and forth along the axis of the protective tube via the servo motor for precise position adjustment. This rack and pinion combined with servo drive offers advantages such as high positioning accuracy, fast response speed, and strong anti-interference capability. As an alternative, those skilled in the art can also select a linear module with a ball screw and servo motor, or a linear motor drive method, depending on the actual load and operating conditions, to achieve higher dynamic response or a quieter operating environment.

[0022] It also includes a clamping plate assembly, which is mounted on the sliding plate 19. (Continue to refer to...) Figure 1 As shown, the clamping assembly includes two opposing clamping plates 15 and a drive unit that drives the two clamping plates 15 to clamp the protective tube. The two clamping plates 15 are located on opposite sides of the protective tube. When the protective tube is placed on the frame 11, it is positioned between the two clamping plates 15. The drive unit then moves the clamping plates 15 closer to the protective tube, thus clamping it. The drive unit includes a forward and reverse lead screw 17 driven by a servo motor 171. The motor drives the lead screw to rotate forward and backward, thereby moving the two clamping plates 15 closer or further apart to clamp and release the protective tube. The forward and reverse lead screw structure has advantages in terms of good synchronization and high centering accuracy, making it particularly suitable for scenarios requiring repeated and precise positioning. As an optional implementation, dual independent cylinders or hydraulic cylinders can be used to drive the clamping plates on both sides separately, with a linear displacement sensor for synchronous control. This method has better adaptability when the clamping force requirement is high or the tube diameter varies significantly. Since this part has been described in more detail in prior patents, the technical details will not be repeated here, including the connection between the lead screw and the clamping plate 15, the fixed roller 14 at the rear end of the clamping plate 15, and the support roller 12 structure at the end of the frame 11 that can be driven up and down by the electric cylinder 13. During feeding, the support roller 12 can first rise to act as a blocking and positioning device, and then descend to a supporting state after the pipe is in place, thereby ensuring the consistency of the starting position of each feeding. Those skilled in the art can adapt the installation based on common knowledge in the field or the disclosure of prior patents to achieve the technical effects expressed in this embodiment.

[0023] The cutting device 2 shares similarities with the cutting box structure in the prior patent, but it features substantial improvements in key structural layouts and tool configuration. The cutting device 2 comprises a mounting bracket 21 and a housing 22. (See reference...) Figure 2 As shown, a positioning disk 24 is provided at the rear end of the housing 22, i.e., at the end of the cutting device 2 facing the receiving device 3. The structure of the positioning disk 24 is the same as that of the positioning disk in the prior patent, both including several rotatable clamping claws 25. Clamping rollers are installed at the ends of the clamping claws 25, and one end of the clamping claw 25 is hinged to the disk body of the positioning disk 24. Centering and clamping are achieved by the clamping electric cylinder 23 and the synchronous connecting rod 26 hinged to the end of the clamping claw. This structure can ensure that the pipe remains in a stable relative position with the cutting tool during the cutting process, avoiding uneven cutting end face or dimensional deviation caused by pipe sway.

[0024] In addition, a lifting device 27 for driving the box 22 to move up and down is installed on the top of the box 22. A guide rail 29 is provided on the mounting bracket 21, and guide wheels adapted to the guide rail 29 are provided on the side of the box 22 to realize the guiding function during lifting. This lifting mechanism can adaptively adjust the center height according to different pipe diameters, so that the cutting tool is always aligned with the center of the pipe and the cutting quality is improved.

[0025] In addition, a drive mechanism is provided in the drive housing 22 to rotate the cutting mechanism around the axis of the protective tube. Its structure and principle are consistent with those described in the prior patent. It adopts a gear and gear ring structure and drives the cutting mechanism to rotate circumferentially through a servo system to achieve ring cutting.

[0026] The difference between this embodiment and the prior patent in terms of the cutting device lies in the blade arrangement of the cutting mechanism itself. (Refer to...) Figure 3 As shown, this embodiment independently designs two sets of cutters: a cold-cutting cutter 227 and a powered cutter 226. The two cutters are arranged opposite each other, with the cold-cutting cutter 227 mounted on the upper cutter holder 221 and the powered cutter 226 mounted on the lower cutter holder 224, and the torque for rotation during cutting is provided by a motor 225. Each of the upper and lower cutter holders is equipped with a sliding mechanism, including an upper slide rail 222 and a lower slide rail 223 mounted on the cutting mechanism, as well as a lead screw drive assembly. The two cutter holders are independent of each other and can be advanced or retracted along their respective slide rails towards the center of the pipe without interference.

[0027] The power cutter 226 of this application is equivalent to the saw blade of the prior patent, suitable for high-speed cutting, especially for thick-walled pipes or stainless steel protective pipes, with good cutting efficiency; the cold cutting blade 227 is equivalent to the cutting blade of the prior patent, suitable for thin-walled pipes or plastic pipe fittings, producing a smooth, burr-free, and dust-free cut. The prior patent integrates the two blades on the same side, and then switches their positions to achieve function switching. In this embodiment, the two blades are set on opposite sides, and when a particular blade is needed, it is pushed out towards the axis through an independent sliding mechanism. The advantage of this design is that it has higher fault tolerance, the blades are separated, and there will be no structural interference or chip interference, and the safety is also higher. At the same time, since the two sets of blades can move independently, they can also be disassembled and installed separately for maintenance, significantly improving the convenience of maintenance. In addition, this layout reserves structural expansion space for the addition of more types of blades (such as chamfering blades, grooving blades, etc.), making the equipment more adaptable to different processes.

[0028] Furthermore, the prior patent positioned two blades on the same side and a similarly slidable counterweight mechanism on the other side to ensure the stability of the protective tube during cutting. This embodiment also employs a similar structure. Since blades are mounted on both sides of the cutting mechanism, this embodiment places the counterweight mechanism 211 independently of the cutting mechanism, on the outside of the cutting device mounting bracket 21. (Refer to...) Figure 4 As shown, the counterweight mechanism 211 is located at the end of the mounting frame 21 and is connected to the counterweight block via a lifting cylinder. The cylinder drives the counterweight block to press down on the protective tube during cutting, thus achieving a stable counterweight effect. This design differs from previous patents in that when the counterweight is pressed down, the vibration of the protective tube is not directly fed back to the mounting platform of the cutting mechanism (during cutting, the cutting mechanism rotates as a whole), making the cutting more stable. Especially when cutting large-diameter pipes, it can effectively suppress the vibration of the pipe caused by gravity or cutting force, thereby improving the quality of the cut end face. As an optional solution, the lower surface of the counterweight block can be designed as a V-shaped or arc-shaped structure, forming a wrapping contact with the outer wall of the pipe, increasing the contact area and further improving stability.

[0029] The structure of receiving device 3 is referenced. Figures 5 to 7 As shown, this is one of the core improvements of the present invention. The receiving device 3 includes a receiving box 36, which is mounted on a platform 33 located at the bottom. The platform 33 is mounted on a linear slide rail 32 at one end of the worktable. Driven by a servo, the platform 33 can slide along the linear slide rail 32. The sliding direction is along the axis of the protective tube, allowing it to move closer to or further away from the cutting device 2. This sliding function allows the receiving device to flexibly adjust its receiving position according to the different lengths of the cutting material segments. For long material segments, it moves back to make room, and for short material segments, it extends forward to achieve precise docking with the cutting device.

[0030] Continue to refer to Figure 6 As shown, a rotating bearing 362 is provided on the upper part of the platform 33, and a rotating seat is provided on the bottom of the receiving box 36. The rotating seat is rotatably connected to the platform 33 via the rotating bearing 362, and the rotatable central axis of the receiving box 36 is vertical. The rotation of the receiving box 36 is powered by a motor 363 at the bottom. Through this rotating mechanism, the receiving box can rotate at any angle in the horizontal plane, thereby realizing rapid switching between different clamping fixtures.

[0031] A lifting servo cylinder 361 is installed on the upper part of the rotary table, along with a vertical sliding rail. Through the connection of the lifting servo cylinder 361, the receiving box 36 can be raised and lowered vertically on the rotary table to adjust the discharge height of the cutting device 2. The combination of lifting and rotation gives the receiving box a multi-degree-of-freedom spatial adjustment capability, which can adapt to different pipe diameters and different cutting station height changes, while ensuring the alignment accuracy of the clamping fixture and the central axis of the positioning plate 24.

[0032] Continue to refer to Figure 5 As shown, the receiving box 36 has several clamping fixtures on its peripheral sidewalls for receiving materials. The rotating function of the receiving box 36 allows different clamping fixtures to be aligned with the positioning plate 24 of the cutting device 2, thus enabling material reception after cutting. This turret-style structure design allows multiple clamping fixtures to be "pre-installed" on the receiving box. When switching processing specifications, there is no need to change the fixtures; a quick switch can be completed simply by rotating, greatly shortening equipment adjustment time and improving the flexibility of the production line.

[0033] The receiving box 26 in this embodiment has a quadrilateral cross-section, thus having four peripheral surfaces on which four different clamping fixtures are installed. Based on the guidance of this application, those skilled in the art can adaptively design different numbers of peripheral surfaces to install different numbers of clamping fixtures to meet operational needs. For example, when the processing specifications are relatively simple but the cycle time requirement is high, a three-station structure can be adopted, where two stations use clamping fixtures of the same specifications to achieve alternating material receiving; when there are many processing specifications, a five-station or six-station structure can be designed to accommodate more types of clamping fixtures.

[0034] Only with Figure 5 For example, the clamping fixture mainly includes three chuck fixtures 31 of different sizes and opposing clamping plates 34. The chuck fixtures 31 are used for receiving short materials, while the opposing clamping plates 34 are used for receiving long materials. The three different chuck fixtures correspond to pipe fittings with different inner diameter ranges. For example, the small-diameter chuck is suitable for pipe fittings with an inner diameter of 20-40mm, the medium-diameter chuck is suitable for 40-80mm, and the large-diameter chuck is suitable for 80-120mm. In actual use, they can be quickly rotated and switched according to order requirements. The opposing clamping plates 34 are mainly used for clamping long material sections. Its clamping method is external clamping, which is more suitable for stable clamping of long material sections after they extend out of the cutting device compared to the internal support method of the chuck.

[0035] Reference Figure 7As shown, the opposing clamping fixture 34 includes movable clamping plates 341 vertically mounted on opposite sides. The movable clamping plates 341 are respectively configured on two independent racks 342, which mesh together with a central gear 343 located in the middle. Driven by a motor, the central gear 343 drives the racks 342 and the movable clamping plates 341 to move closer or further apart using forward and reverse rotation. This synchronous gear and rack structure ensures completely symmetrical movement of the movable clamping plates 341 on both sides, resulting in good centering and uniform clamping force. As an alternative, the movable clamping plates can also be driven using a dual-cylinder system with a proportional valve, offering greater flexibility in scenarios requiring adjustable clamping force or special clamping speed requirements.

[0036] Continue to refer to Figure 7 As shown, the opposing clamping plate fixture 34 also includes a telescopic roller 35, which is fixedly installed at the front end of the telescopic plate 351. The telescopic plate 351 has slide rails on both sides that are slidably connected to the housing of the receiving box 36. The receiving box 36 is also equipped with a telescopic cylinder 352 for driving the telescopic plate 351 to extend and retract, thereby adjusting the lateral span distance of the telescopic roller 35 relative to the moving clamping plate 341. During the feeding of long material sections, the roller can extend outward with the telescopic plate, providing auxiliary support for the middle or end of the long material section, preventing sagging deformation due to excessive length, and facilitating material handling by the feeding mechanism or operators. The surface of the roller can be covered with polyurethane or rubber material to avoid scratching the surface of the pipe fittings.

[0037] Based on the above structure, the present invention mainly includes the following steps when cutting cable protection pipes: Cutting steps: The protective tube is transferred to the support roller 12 of the feeding device 1 using a roller conveyor or transfer cart. At this time, the support roller 12 is raised to act as a stop, ensuring that each tube is in the same starting position. This stopping method is more accurate than traditional manual positioning and requires no additional manual intervention.

[0038] After inputting the cutting parameters (including pipe diameter, wall thickness, cutting length, cutting mode, etc.), start the cutting device 2. The control system automatically matches the process parameters such as feed speed, cutting speed, tool selection, and clamping force according to the input parameters.

[0039] The support roller 12 falls, turning its obstruction into support, and the protective tube lands smoothly on the support roller 12 and the fixed roller 14.

[0040] The clamping plate 15 holds the protective tube and moves towards the inside of the cutting box 22. The specific moving distance is determined according to the cutting parameters. During the feeding process, the clamping plate 15, the support roller 12, and the idler roller 14 form a three-point support to ensure smooth axial movement of the tube.

[0041] The counterweight mechanism 211 inside the housing 22 presses down on the protective tube, the positioning plate 24 clamps and positions the protective tube, and the cutting mechanism is activated to perform a circumferential cut on the protective tube. When the counterweight mechanism 211 presses down, its pressure block contacts the outer wall of the tube and applies a preset downward pressure, effectively suppressing the vibration caused by the cutting tool during the cutting process.

[0042] When cutting longer sections of material, the clamping plate 15 and the counterweight mechanism 211 need to work in conjunction with the translation axis to repeatedly perform the actions of clamping plate 15 moving left, clamping, releasing, moving right, clamping, releasing, and moving left to continuously drag the protective tube. This "stepping" feeding method enables the cutting device to handle sections of material that are much longer than the device's own stroke, greatly expanding the processing range of the equipment.

[0043] Short material receiving steps: The corresponding chuck fixture 31 is automatically selected based on the parameters of the protective tube (such as inner diameter, material, and length), and rotated to face the cutting device. At the same time, the front end of the chuck fixture 31 can be inserted into the channel of the housing 22 through lifting and translating actions, so as to achieve alignment with the center of the positioning plate 24.

[0044] The chuck fixture 31 opens the chuck jaws to support the inner wall of the protective tube, forming an internal support clamping mechanism. The cutting device 2 then starts to cut the protective tube to the specified length. During this process, the chuck fixture 31 and the positioning plate 24 work together to clamp the tube, ensuring that the tube does not wobble during cutting.

[0045] Positioning plate 24 releases the protective tube, chuck fixture 31 independently clamps the protective tube, and the cut-off protective tube is brought out of box 22 by the translation of the receiving box. This translational withdrawal method can prevent the cut short material segment from tipping over or getting stuck in the box.

[0046] The receiving box rotates 180°, moving the chuck fixture 31 with the protective tube to the outermost position, while simultaneously lowering its height to discharge the material. During discharge, short material segments can be removed from the chuck fixture using air blowing or a pusher rod and fall into the material box or conveyor belt.

[0047] Long material receiving steps: The receiving box rotates, causing the opposing clamping plate fixture 34 to rotate to the side facing the cutting device 2. At the same time, the lifting height is adjusted so that the center of the moving clamping plate 341 is at the same height as the center of the pipe fitting.

[0048] The long section extends from the pipe cutting channel under the action of the feeding device 1, and the opposing clamping plate fixture 34 clamps and fixes its end. Since the long section may have extended a long distance during the cutting process, the external clamping can avoid the pipe end deformation problem that may be caused by the internal support clamping.

[0049] The receiving box retracts, carrying the cut material segment out of the cutting device 2. During this process, the translational speed of the receiving box must match the feed speed of the cutting device to prevent the material segment from bending.

[0050] Rotate the receiving box 180° to rotate the side where the opposing clamping plate fixture 34 is located to the outermost side for material feeding.

[0051] During the feeding process, the retractable roller 35 pushes the long material section, allowing it to smoothly detach from the moving clamp 341 and be conveyed to the unloading rack or stacking area. When the material section is long, it can be used in conjunction with an external auxiliary support frame.

[0052] The above steps can be combined and cycled according to the actual production cycle and pipe specifications to achieve full automation from feeding, cutting to receiving and unloading.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, such as replacing some servo drives with a combination of stepper motors and closed-loop control, or replacing linear guides with high-rigidity roller guides to accommodate heavier loads. The scope of the invention is defined by the appended claims and their equivalents.
