Technical Field

[0001] The invention relates to the field of cable ring cutting equipment, in particular to a cable processing ring cutting system with a waste collection function. Background Art

[0002] Cables are wire products used to transmit electrical energy or information. They are generally composed of one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] A Chinese patent with relevant announcement number CN111817213B discloses a cable processing ring cutting system with a waste collection function, including a base, with support legs fixedly connected at the four corners of the bottom of the base, a cable fixing assembly is provided on the top of the base, the cable fixing assembly fixes the cable, a cable ring cutting assembly is provided on the rear side of the cable fixing assembly, the cable ring cutting assembly ring cuts the cable, a waste box is slidably connected to the bottom of the base through a slide rail, a material discharge slot is opened on the base, the material discharge slot is located directly above the waste box, and a waste cleaning assembly is installed on the base.

[0004] In the prior art, manual tools can also be used to perform cable ring cutting. The manual tools are composed of two symmetrical components connected in a detachable manner. When in use, the two components are first installed on the part of the cable to be cut, and then the cable is rotated along the axis to complete the cable ring cutting. The next section of the ring cutting work can only be carried out after the manual tool is removed.

[0005] With respect to the above-mentioned related technologies, the existing cable processing ring cutting equipment can generally only perform ring cutting on both ends of the cut cables. When extending a large number of cables with connecting terminals, it is necessary to first cut the cables of appropriate length and then perform ring cutting on both ends to facilitate connecting the corresponding terminals at the ends of the cables. The process of cutting the rolled cables and then performing ring cutting on both ends and connecting the terminals is relatively long, and the production and processing efficiency is relatively low. In summary, the existing cable processing ring cutting system is not suitable for continuous ring cutting of the ends of cables. Summary of the invention

[0006] Based on this, the purpose of the present invention is to provide a cable processing ring cutting system with a waste collection function to solve the technical problem that the existing cable processing ring cutting system is not suitable for continuously ring cutting the ends of the cables.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a circular cutting system for cable processing with a waste collection function, comprising a chassis, a conveying mechanism for conveying cables is arranged in the chassis along the length direction, a space for accommodating cable cuttings is arranged in the chassis, and also comprises a chassis cover, the chassis cover is fixedly connected to the top of the chassis, a frameless torque motor is installed at the top of the inner wall of the chassis cover, and at least one fixed cylinder is fixedly installed in the frameless torque motor toward the center of a circle, a telescopic cylinder is slidably connected in the fixed cylinder, and two groups of blades with orthogonal blade directions and different extension states are slidably connected in the telescopic cylinder, and the blade directions of one group of blades are parallel to the length direction of the cable.

[0008] By adopting the above technical scheme, when the cable is conveyed into the chassis, one end is first ring-cut and then the cable is longitudinally cut to the required length along the cable conveying direction, and then ring-cut again. The end ring-cutting work between two adjacent cables can be completed without cutting the cable line. The cable can be quickly ring-cut at the end during continuous transportation, and then the cable can be cut from the middle of the ring-cut part for subsequent terminal installation, which greatly improves the cable ring-cutting efficiency.

[0010] Preferably, the sliding table enables the frameless torque motor to move along with the cable, so that the conveying of the cable does not need to be suspended when the cable ring cutting operation is being performed.

[0011] The present invention is further configured as follows: a fixed shaft is coaxially connected inside the telescopic cylinder, and four guide strips are fixedly connected to the bottom end of the fixed shaft, and the guide strips are arranged along the annular surface at an interval of ninety degrees from each other, and two opposite guide strips are respectively connected to a first blade and a second blade, and the ends of the tops of the first blade and the second blade away from the guide strips are both rotatably connected to the second telescopic rod, and the other ends of the second telescopic rod are rotatably connected to the top of the inner wall of the telescopic cylinder, and the guide strips are provided with sliding grooves along the length direction, and the ends of the tops of the first blade and the second blade away from the second telescopic rod are both rotated and slidably connected in the sliding grooves, and matching grooves matching the guide strips are provided in the first blade and the second blade facing the guide strips.

[0012] Preferably, the first blade and the second blade are intermittently retracted and extended to achieve circumferential cutting and longitudinal cutting of the cable sheath while controlling the extension length of the telescopic tube.

[0013] The present invention is further configured such that the frameless torque motor in the mounting frame is provided with a guiding structure for guiding the cable at one end from which the cable comes.

[0014] Preferably, the guiding structure further improves the quality of cable ring cutting.

[0015] The present invention is further configured such that the mounting frame is fixedly connected with a fixing ring at one end of the cable direction, the center of the fixing ring is fixedly connected with a first guide ring, and the center of the first guide ring is provided with a through hole which is coaxial with the cable and has the same diameter as the cable.

[0016] Preferably, the cable to be circumscribed is kept coaxial with the frameless torque motor.

[0017] The present invention is further configured such that the rotor is fixedly connected to a second guide ring at one end in the direction of cable origin, a through hole coaxial with the cable and having the same diameter as the cable is opened at the center of the second guide ring, and friction blocks are arranged at annular intervals on the inner wall of the center through hole of the second guide ring.

[0018] Preferably, a certain torque is applied to the outer sheath of the cable while the circular cutting is performed, so that the cable sheath is easier to fall off in the subsequent longitudinal cutting process.

[0019] The present invention is further configured such that the chassis is provided with a first supporting roller frame, a sliding track, a fixed frame, a first conveying roller frame, a second supporting roller frame, and a second conveying roller frame in sequence along the conveying direction of the cable, and the chassis is provided with a storage bin for accommodating cable cuttings between the fixed frame and the first supporting roller frame.

[0020] Preferably, two groups of supporting structures are used to maintain stable transportation of the cable, and two groups of conveying roller frames are used to straighten the cable and ensure continuous transportation of the cable.

[0021] The present invention is further configured such that the bottom end of the fixed frame is rotatably connected to two rotating tables, the rotating tables are respectively located on both sides of the cable, and are both rotatably connected to cleaning rollers, the cleaning rollers are able to contact both sides of the upper part of the cable after rotating along the rotating axis of the rotating table under their own gravity, and the cleaning direction of the cleaning rollers contacting the outer surface of the cable is opposite to the conveying direction of the cable.

[0022] Preferably, the cleaning roller cleans both sides of the top of the cable sheath, so that the cut cable sheath can smoothly fall off from the cable and fall into the receiving bin.

[0023] The present invention is further configured such that the interval between the first conveying roller frame and the second conveying roller frame is greater than the length of a single section of the cable cut along the axial direction.

[0024] Preferably, it is prevented that the two conveying roller frames contact the peeled cable portion at the same time to cause the inner core wire of the cable to slide relative to the cable outer shell.

[0025] The present invention is further configured such that a bracket is coaxially fixedly connected to the center of the rotor, and an end of the fixing tube passes through the bracket.

[0026] Preferably, the bracket plays a role of supporting the end of the fixed tube, effectively preventing the fixed tube from being deformed during the cutting process.

[0027] In summary, the present invention mainly has the following beneficial effects:

[0028] 1. The present invention installs two sets of retractable and switchable cutting tools on the inner ring of the frameless torque motor toward the center, and the blades of the two sets of cutting tools are oriented orthogonal to each other. When the cable is conveyed into the chassis, one end is firstly ring-cut and then the cable is longitudinally cut to the required length along the cable conveying direction, and then the ring-cut is performed again. The end ring-cutting work between two adjacent cables can be completed without cutting the cable line. The cable can quickly complete the ring-cutting of the end during continuous conveying, and then the cable can be cut from the middle of the ring-cut part for subsequent terminal installation, which greatly improves the cable ring-cutting efficiency.

[0029] 2. The present invention installs a sliding structure that can move along the cable conveying direction at the top of the ring cutting mechanism. During the cable ring cutting process, the sliding structure can move toward the cable conveying direction at the same speed as the cable conveying. There is no need to suspend the cable conveying during the ring cutting process, thereby further improving the cable ring cutting efficiency.

[0030] 3. The present invention installs a guide mechanism for guiding the cable in the direction of the cable feeding of the circular cutting mechanism, so that the cable can be kept coaxial with the circular cutting mechanism as much as possible when passing through the circular cutting mechanism, thereby effectively improving the cutting quality of the circular cutting mechanism and avoiding damage to the inner conductor of the cable;

[0031] 4. The present invention fixes a guide mechanism for guiding the cable on the rotor of the motor so that the guide mechanism can rotate synchronously with the rotor. The friction block on the inner wall of the guide structure contacts the outer surface of the cable, and applies torque to the outer skin of the cable during the ring cutting process, so that the cable skin can fall off more smoothly when cutting along the length direction of the cable later.

[0032] 5. The present invention arranges a cleaning mechanism behind the ring cutting mechanism of the cable conveying line. The cleaning mechanism contacts the cable sheath that is ring cut and cut along the length direction, and can easily sweep the cable sheath off the surface of the cable after cutting, to avoid the cable sheath adhering to the cable and being carried out of the chassis. The cable sheath that falls from the cable can smoothly fall into the collecting structure in the chassis, to avoid the cable sheath from scattering after being carried out by the cable belt, and effectively saves the workload of cleaning the cable sheath.

[0051] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0052] The following describes an embodiment of the present invention based on its overall structure.

[0053] First embodiment:

[0054] A cable processing ring cutting system with waste collection function, see Figure 1-16 , including a chassis 1, a conveying mechanism for conveying cables is arranged in the chassis 1 along the length direction, and a space for accommodating cable cuttings is arranged in the chassis 1. Specifically, the space for accommodating cable cuttings in the chassis 1 is specifically a accommodating bin 101.

[0055] It also includes a chassis cover 2, which is fixedly connected to the top of the chassis 1. A frameless torque motor is installed on the top of the inner wall of the chassis cover 2, and at least one fixed cylinder 9 is fixedly installed in the frameless torque motor toward the center of the circle. In the present embodiment, the number of the fixed cylinders 9 is specifically three. The specific number of the fixed cylinders 9 can be appropriately increased or decreased according to the inner diameter size of the frameless torque motor. The three fixed cylinders 9 in the present embodiment are arranged on the annular surface at an interval of one hundred and twenty degrees from each other.

[0056] Furthermore, a telescopic cylinder 11 is slidably connected inside the fixed cylinder 9, and two first telescopic rods 10 are arranged between the mounting seat of the fixed cylinder 9 and the end of the telescopic cylinder 11. The distance between the end of the telescopic cylinder 11 and the cable is controlled by controlling the elongation of the first telescopic rod 10, thereby realizing circular cutting of cables with different diameters and outer skin thicknesses. Two groups of blades with orthogonal blade directions and different extension states are slidably connected inside the telescopic cylinder 11, and the blade direction of one group of blades is parallel to the length direction of the cable. Each group of blades includes two blades with opposite blade directions, and the two groups of blades are respectively used for circumferential cutting and longitudinal cutting of the cable.

[0057] In the above embodiments, please refer to Figure 2-5 A sliding track 3 is installed on the inner wall of the chassis cover 2, and a sliding table 4 is slidably connected to the sliding track 3 along the conveying direction of the cable. Specifically, the sliding table 4 is controlled by a servo motor. The detailed steps of specifically controlling the sliding of the sliding table 4 are recorded in detail in the prior art, and those skilled in the art can easily understand it and will not be repeated here. Specifically, the speed of the sliding table 4 moving in the same direction as the cable is equal to the conveying speed of the cable, thereby improving the quality of the cable ring cutting process. When the sliding table 4 slides in the opposite direction to the conveying direction of the cable, the first blade 13 cuts the outer skin of the cable along the length direction of the cable. After the sliding table 4 slides and resets, the cable continues to be conveyed and the outer skin of the cable in the length direction can still be cut.

[0058] Furthermore, the bottom end of the sliding table 4 is fixedly connected to the stator 6 of the frameless torque motor through the mounting frame 5, and the rotor 7 is rotatably connected inside the stator 6. The rotor 7 is specifically annular in structure, and the inner wall of the rotor 7 is fixedly connected to a fixing cylinder 9 toward its own axis. The center of the rotor 7 is coaxially fixedly connected to a bracket 8, and the end of the fixing cylinder 9 passes through the bracket 8. The bracket 8 supports the end of the fixing cylinder 9, effectively preventing the fixing cylinder 9 from being deformed during the cutting process. The sliding table 4 enables the frameless torque motor to move with the cable line, and there is no need to suspend the transportation of the cable line when performing the cable line ring cutting work, which further improves the cable line ring cutting quality and also prevents the cutting knife from being broken.

[0059] In the above embodiments, please refer to Figure 9-16 A fixed shaft 12 is coaxially connected to the telescopic cylinder 11, and four guide bars 16 are fixedly connected to the bottom end of the fixed shaft 12. The guide bars 16 are provided with slide grooves 1601 along the length direction, and the guide bars 16 are arranged at a 90-degree interval along the annular surface.

[0060] Specifically, the two opposing guide bars 16 are respectively connected to the first blade 13 and the second blade 14. The ends of the tops of the first blade 13 and the second blade 14 away from the guide bars 16 are both rotatably connected to the second telescopic rod 15. The other end of the second telescopic rod 15 is rotatably connected to the top of the inner wall of the telescopic tube 11. When the second telescopic rod 15 is extended to its longest position, the two corresponding first blades 13 or the second blades 14 contact each other.

[0061] Furthermore, the top ends of the first blade 13 and the second blade 14 away from the second telescopic rod 15 are both rotated and slidably connected in the slide groove 1601, and the first blade 13 and the second blade 14 are provided with matching grooves 17 that match the guide bar 16 toward the guide bar 16. The first blade 13 and the second blade 14 intermittently retract and extend, thereby realizing circumferential cutting and longitudinal cutting of the cable sheath while controlling the extension length of the telescopic tube 11.

[0062] For example, when the first blade 13 is switched from the extended state to the second blade 14, the two second telescopic rods 15 corresponding to the first blade 13 are retracted, so that the end of the first blade 13 away from the guide strip 16 is lifted, and the first blade 13 rotates around the portion connected to the guide strip 16 to the state of contacting the inner wall of the telescopic tube 11. As the second telescopic rod 15 continues to retract, the portion of the first blade 13 located in the slide groove 1601 slides upward, and the first blade 13 moves upward in an inclined state until the portion of the first blade 13 located in the slide groove 1601 cannot continue to rise, and the first blade 13 is blocked by the inner wall of the telescopic tube 11 and cannot rotate, then the second telescopic rod 15 corresponding to the first blade 13 stops retracting;

[0063] The second telescopic rod 15 corresponding to the second blade 14 is extended, pressing down the end of the second blade 14 away from the guide strip 16. While the second blade 14 descends, it rotates around the part located in the slide groove 1601 until the second blade 14 can no longer move downward in the slide groove 1601. As the second telescopic rod 15 continues to extend, the second blade 14 rotates around the part located at the bottom end of the slide groove 1601, approaching and contacting each other, and the matching groove 17 in the second blade 14 is engaged with the bottom end of the guide strip 16, and the second telescopic rod 15 stops extending, thereby realizing the switching between the first blade 13 and the second blade 14, and vice versa.

[0064] When the second blade 14 or the first blade 13 is in the extended state, there is no additional friction resistance with the cable except the blade body, and each set of blades contacts each other and engages with the guide strip 16 after being extended, which can effectively prevent the blade structure from breaking during the cutting process. If a tool that extends and retracts parallel to the axial direction of the fixed shaft 12 is directly used, it is difficult to ensure that the two sets of tools are at the same distance from the center of the cable when extended, which is prone to cutting errors, and the blade strength may be reduced compared to the present application, making it difficult to continuously perform high-intensity cable cutting work.

[0065] In the above embodiments, please refer to Figure 4-6 The frameless torque motor in the mounting frame 5 is provided with a guiding structure for guiding the cable at one end of the cable, and the guiding structure further improves the quality of the cable ring cutting.

[0066] Specifically, the mounting frame 5 is fixedly connected with a fixing ring 18 at one end of the cable direction. The radial cross-section of the fixing ring is rectangular, which is used for fixed installation of the first guide ring 19. The center of the fixing ring 18 is fixedly connected with the first guide ring 19. The center of the first guide ring 19 is provided with a through hole coaxial with the cable and with the same diameter. The radial cross-section of the first guide ring 19 is funnel-shaped, which is convenient for guiding the cable to the center through hole, so that the cable to be ring-cut remains coaxial with the frameless torque motor, which is convenient for improving the quality of cable ring cutting.

[0067] In the above embodiments, please refer to Figure 1-2 The chassis 1 is provided with a first supporting roller frame 25, a sliding track 3, a fixed frame 21, a first conveying roller frame 27, a second supporting roller frame 26, and a second conveying roller frame 28 in sequence along the conveying direction of the cable.

[0068] Specifically, the first supporting roller frame 25 and the second supporting roller frame 26 in this embodiment are both composed of three guide wheels, and the six guide wheels can be extended and retracted in the vertical direction. Two of them are installed on the chassis cover 2, and the other four are installed on the top of the chassis 1. Among every three guide wheels, the installation position of the guide wheel located in the middle is different from that of the two adjacent guide wheels. The first supporting roller frame 25 and the second supporting roller frame 26 both play the role of supporting cables.

[0069] Furthermore, the first conveying roller frame 27 and the second conveying roller frame 28 are both composed of retractable conveying rollers arranged opposite to each other. The conveying rollers arranged opposite to each other clamp the cable, and can maintain stable conveying of the cable when the first conveying roller frame 27 and the second conveying roller frame 28 are working. The retraction and extension of the conveying roller structure and the retraction and extension of the supporting roller frame structure are both mature solutions in the prior art and will not be elaborated here. Two groups of supporting structures are used to maintain stable conveying of the cable, and the two groups of conveying roller frames are used to straighten the cable and ensure continuous conveying of the cable. The interval between the first conveying roller frame 27 and the second conveying roller frame 28 is greater than the length of a single section of the cable cut along the axial direction, so as to avoid the two conveying roller frames contacting the peeled cable part at the same time and causing the inner core wire of the cable to slide relative to the cable outer casing.

[0070] In the above embodiments, please refer to Figure 1-2 A storage bin 101 for storing cable cuttings is provided between the fixed frame 21 and the first supporting roller frame 25 of the chassis 1, and a bin door 102 is also provided at a position corresponding to the storage bin 101 on one side of the chassis 1. After opening the bin door 102, the waste cuttings in the storage bin 101 can be easily cleaned.

[0071] Second embodiment:

[0072] A cable processing ring cutting system with waste collection function, see Figure 1-16 The rotor 7 is fixedly connected with a second guide ring 20 at one end of the cable. A through hole coaxial with the cable and having the same diameter as the cable is opened in the center of the second guide ring 20. Specifically, the radial cross-section of the second guide ring 20 is also funnel-shaped, which is convenient for the cable to enter the central through hole better. The second guide ring 20 is provided with friction blocks 2001 at annular intervals on the inner wall of the central through hole. A certain torque is applied to the outer skin of the cable during the circumferential cutting, thereby making it easier for the cable skin to fall off in the subsequent longitudinal cutting process.

[0073] Specifically, the friction block 2001 contacts the outer skin of the cable body 24. During the rotation of the rotor 7, the friction force between the friction block 2001 and the outer skin of the cable body 24 twists the cut cable skin, causing the cable skin to undergo elastic deformation. When the tool is quickly switched and cut along the length direction of the cable body 24, after the tool cuts open the outer skin of the cable body 24, the outer skin of the cable body 24 is not easily adhered to the inner core wire of the cable due to the release of elastic force, thereby facilitating the shedding of the cable skin.

[0074] The third embodiment:

[0075] A cable processing ring cutting system with waste collection function, see Figure 1-16 The bottom end of the fixed frame 21 is rotatably connected to two rotating tables 22, which are respectively located on both sides of the cable and are rotatably connected to cleaning rollers 23. Specifically, the cleaning rollers 23 are brush rollers, which are rotated by a driving motor installed on the rotating table 22. The cleaning rollers 23 are able to contact both sides of the upper part of the cable after rotating along the rotating axis of the rotating table 22 due to their own gravity.

[0076] Specifically, before the cable enters the chassis 1, the two cleaning rollers 23 hang down due to their own gravity and are parallel to each other, and the distance between them is smaller than the diameter of the cable body 24 to be entered. After the cable body 24 enters, the two cleaning rollers 23 will be pushed open and rotated away from each other. The cleaning direction of the cleaning rollers 23 contacting the outer surface of the cable is opposite to the conveying direction of the cable. The cleaning rollers 23 clean both sides of the top of the cable sheath, so that the cut cable sheath can smoothly fall off the cable and fall into the storage bin 101.

[0077] When the present invention performs continuous cable ring cutting, the cable is fed into the end of the chassis 1 and passes through the first supporting roller frame 25, the center of the guide structure, the center of the rotor 7, between the two cleaning rollers 23, the first conveying roller frame 27, the second supporting roller frame 26, the second conveying roller frame 28, and finally leaves from the other end of the chassis 1.

[0078] When the cable needs to be circumcised, the second blade 14 extends out of the telescopic cylinder 11, and the telescopic cylinder 11 extends to a suitable length, so that the second blade 14 penetrates the outer skin of the cable. The sliding table 4 moves synchronously and at the same speed as the cable, and the rotor 7 starts to rotate to perform circumcision of the cable. The circumcision is completed before the sliding table 4 moves to the end of the stroke. The second blade 14 and the first blade 13 in the telescopic cylinder 11 switch to the extended state. After the first blade 13 penetrates the cable to the same depth, the sliding table 4 quickly moves in the opposite direction and resets to perform longitudinal cutting on the outer skin of the cable, and then repeats the above circumcision steps again to perform secondary circumcision, and finally the sliding table 4 resets.

[0079] The cut cable sheath falls into the containing bin 101, which is convenient for opening the bin door 102 for cleaning and collection. When the cable continues to be transported and needs to be cut again, the above steps are repeated to remove the next section of the cable sheath. After the cut cable part is cut off from the middle, it is equivalent to the product obtained by first cutting the cable and then ring cutting the two ends of the cable in the prior art. When performing large-scale cable ring cutting work, it can effectively improve the efficiency of cable ring cutting and reduce the labor intensity of workers.

[0080] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
