Background Art

[0002] Cable is a device used to transmit power or signals and is widely used in various fields. According to different installation environments and project requirements, longer cables can be cut and slit into appropriate lengths according to actual needs, which can reduce waste generation and maximize the utilization of raw materials.

[0003] When the cable is cut, an external device is required to continuously transport the cable for feeding, which can reduce downtime and avoid frequent start and stop operations, thereby greatly improving production efficiency. However, in order to adapt to the cutting process, the cables are usually piled up at the rear end of the cutting process waiting for the next cutting. The cables may bend or deformed due to extrusion or other factors, affecting the cutting accuracy and efficiency of the cables. Summary of the invention

[0004] The present invention aims to solve the problem that the accumulated cables in the prior art may be bent or deformed due to extrusion or other factors, which affects the cutting accuracy and cutting efficiency of the cables. The present invention proposes the following technical solutions:

[0006] The two pulling clamps clamp the stacked cables and move in the feeding direction. The cables drive the two rubber stabilizing layers and the two rotating wheels to rotate on the corresponding shaft surface mounting seats. The cutting and clamping mechanism clamps the cables for cutting after the cable pulling is completed. After the connecting piece connects the shaft and the rotating wheel, the shaft rotates in the opposite direction to the feeding direction, driving the rotating wheels and the rubber stabilizing layer to rotate to straighten the bent cables.

[0007] As a preferred embodiment of the above technical solution, the connecting member includes an insertion shaft, which reciprocates in the direction of the center line of the rotating shaft, a first spring is arranged between the insertion shaft and the rotating shaft, a plurality of plug-in blocks are circumferentially arranged at one end of the insertion shaft, and a corresponding plug-in groove is opened on the surface of the rotating wheel. The insertion shaft moves in the direction of the rotating shaft to push the plug-in block into the plug-in groove to connect the rotating shaft with the rotating wheel.

[0008] As a preferred embodiment of the above technical solution, the straightening assembly also includes two oppositely moving parts, one of which pushes the two pulling clamps to move toward or in opposite directions to complete the cable clamping or releasing work, and the other of which pushes the two mounting seats to move toward or in opposite directions. The two mounting seats move toward each other so that the two rubber stabilization layers are squeezed against each other, increasing the friction with the cable to improve the cable straightening force.

[0009] As a preferred embodiment of the above technical solution, the oppositely moving parts include a mounting block and a screw rod rotatably inserted in the mounting block, one end of the screw rod is connected to an external driving member, both ends of the screw rod are provided with threads arranged in opposite directions, and sliders are sleeved on the threaded surfaces at both ends of the screw rod, and the two sliders are fixedly connected to the corresponding pulling clamps or mounting seats.

[0010] As a preferred embodiment of the above technical solution, the connecting member also includes a second spring and a push rod with an inclined protrusion, one end of the push rod is connected to an external driving mechanism or a mounting block of a pulling clamp, the second spring is sleeved on the surface of the insertion shaft, and the two ends of the second spring are respectively fixedly connected to the push rod and the rotating shaft, the push rod moves in the feeding direction so that the rotating ball is pushed by the inclined protrusion of the push rod to drive the insertion shaft to move in the direction of the rotating shaft.

[0011] As a preferred embodiment of the above technical solution, a rotating ball is provided on one side of the push rod, and the rotating ball is rotatably inserted in the rotating shaft. The rotating ball converts the sliding friction between the push rod and the rotating shaft into rolling friction.

[0012] As a preferred embodiment of the above technical solution, the end of the insertion shaft is truncated into a cone shape, and the surface of the connecting block at the joint matches the insertion shaft.

[0013] As a preferred embodiment of the above technical solution, a working motor with a reduction device is provided on one side of the mounting seat, and an output end of the working motor is fixedly connected to the rotating shaft.

[0014] A straightening method of a straightening device for continuous slitting of metal cables comprises the following steps:

[0015] S1. Pulling the cable: two pulling clamps move toward each other to clamp the cable, and move in the feeding direction to pull the cable to the working position. The distance between this working position and the cutting position is equal to the processing length of the cable;

[0016] S2, cable limit: the two rubber stabilizing layers rotate in the feeding direction as the cable moves, maintaining the limit state of the cable;

[0017] S3, spacing adjustment: the two shafts are moved toward each other through two mounting seats, and the two rubber stabilizing layers are squeezed and deformed against each other to increase the friction coefficient of the cable;

[0018] S4, straightening the cable: after the connector connects the rotating shaft to the rotating wheel, the rotating shaft rotates in the opposite direction of the feeding direction to drive the rotating wheel and the rubber stabilizing layer to rotate, and the cable that is bent due to continuous feeding is straightened;

[0019] S5. Cable cutting: The cutting device cuts off the cable after the cutting clamping mechanism clamps the cable at the cutting position, then pulls the clamping block to release the cable and returns to the initial position to clamp the subsequent cable end, and continues the next cutting work after the cutting clamping mechanism releases the cable.

[0020] The beneficial effects of the present invention are:

[0021] 1. After the shaft is connected to the wheel by a connector, the rubber stabilizing layer used to limit the cable can change the direction of rotation. As the shaft rotates in the opposite direction of the feeding direction, the cable is stretched in the opposite direction through the friction with the cable surface, and the cable in a bent or deformed state can be straightened, thereby improving the consistency of length and cutting accuracy, reducing problems such as uneven cutting surface, burrs or cracks caused by bending, and helping to improve the quality of the final product;

[0022] 2. The arranged moving parts can move the two rotating shafts toward each other through the mounting seat, and the two rubber stabilizing layers squeeze each other and deform, thereby increasing the friction with the cable. When the rotating wheel drives the rubber stabilizing layer to rotate, the straightening force on the cable is increased, thereby preventing the cable from sliding due to the smooth surface and being unable to be straightened.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings of the specification. Example

[0031] Figure 1-Figure 5 The straightening device for continuous slitting of metal cables comprises: a cutting and clamping mechanism 10 and a straightening assembly, wherein the cutting and clamping mechanism 10 is used to clamp the cut portion of the cable during cutting, and is characterized in that the straightening assembly comprises two rotating wheels 22, two rotating shafts 24 and two pulling clamps 21 that reciprocate in the feeding direction, and the specification is attached. Figure 1 A direction is the feeding direction, the instruction manual is attached. Figure 2 The direction opposite to direction A is opposite to the feeding direction. The outer surface of the rotating wheel 22 is provided with a rubber stabilizing layer 23 for supporting and stretching the cable. One end of the rotating shaft 24 is rotatably inserted into the rotating wheel 22. The other end of the rotating shaft 24 is sleeved with a mounting seat 28. A connecting piece 25 is provided between one of the rotating shafts 24 and the corresponding rotating wheel 22, and the rotating shaft 24 rotates in the opposite direction to the feeding direction.

[0032] The two pulling clamps 21 clamp the stacked cables and move in the feeding direction. The cables drive the two rubber stabilizing layers 23 and the two rotating wheels 22 to rotate on the corresponding mounting seats 28 on the surface of the rotating shaft 24. The cutting and clamping mechanism 10 clamps the cables for cutting after the cable pulling is completed. After the connecting piece 25 connects the rotating shaft 24 with the rotating wheel 22, the rotating shaft 24 rotates in the opposite direction to the feeding direction to drive the rotating wheel 22 and the rubber stabilizing layer 23 to rotate to straighten the bent cables.

[0033] When the cable is cut, the external transmission equipment continues to transport the cable. Some cables are gathered at the rear end of the straightening component due to the stop during cutting, resulting in cable bending. Then the two pulling clamps 21 move toward each other to clamp the cable, and move in the feeding direction to pull the cable to the working position. The distance between this working position and the cutting position is equal to the processing length of the cable. In this process, the two rubber stabilizing layers 23 rotate in the feeding direction as the cable moves, maintaining the limited state of the cable. The rotating shaft 24 is connected to the rotating wheel 22 using a connecting piece 25. The rotating shaft 24 rotates in the opposite direction of the feeding direction to drive the rotating wheel 22 and the rubber stabilizing layer 23 to rotate, and the cable bent due to continuous feeding is straightened. The cutting device cuts the cable after the cutting clamping mechanism 10 clamps it at the cutting position. Then the pulling clamp 21 releases the cable and returns to the initial position to clamp the subsequent cable end, and the next cutting work is continued after the cutting clamping mechanism 10 releases the cable.

[0034] After the rotating shaft 24 is connected to the rotating wheel 22 by means of the connecting piece 25, the rubber stabilizing layer 23 for limiting the cable can rotate in the opposite direction of the feeding direction, and the cable can be stretched in the opposite direction by means of friction, so that the cable that is in a bent or deformed state due to continuous feeding can be straightened, ensuring that each cutting is performed at a predetermined position, thereby improving the consistency of length and the cutting accuracy, reducing problems such as uneven cutting surface, burrs or cracks caused by bending, and helping to improve the quality of the final product.

[0035] A straightening method of a straightening device for continuous slitting of metal cables comprises the following steps:

[0036] S1. Pulling the cable: two pulling clamps 21 move toward each other to clamp the cable, and move in the feeding direction to pull the cable to a working position, where the distance from the cutting position is equal to the processing length of the cable;

[0037] S2, cable limiting: the two rubber stabilizing layers 23 rotate in the feeding direction as the cable moves, maintaining the limiting state of the cable;

[0038] S3, spacing adjustment: the two rotating shafts 24 are moved toward each other through the two mounting seats 28, and the two rubber stabilizing layers 23 are squeezed and deformed against each other to increase the friction coefficient of the cable;

[0039] S4, straightening the cable: After the connecting member 25 connects the rotating shaft 24 with the rotating wheel 22, the rotating shaft 24 rotates in the opposite direction of the feeding direction to drive the rotating wheel 22 and the rubber stabilizing layer 23 to rotate, and the cable bent due to continuous feeding is straightened;

[0040] S5. Cable cutting: The cutting device cuts off the cable after the cutting clamping mechanism 10 clamps it at the cutting position, then pulls the clamping block 21 to release the cable and returns to the initial position to clamp the subsequent cable end, and continues the next cutting work after the cutting clamping mechanism 10 releases the cable.

[0041] Figure 3-Figure 5 In the figure, the connecting member 25 includes an insertion shaft 251, which reciprocates in the center line direction of the rotating shaft 24. A first spring 252 is arranged between the insertion shaft 251 and the rotating shaft 24. A plurality of plug-in blocks 253 are circumferentially arranged at one end of the insertion shaft 251. A corresponding plug-in groove 254 is opened on the surface of the rotating wheel 22. The insertion shaft 251 moves toward the rotating shaft 24 to push the plug-in block 253 to be inserted into the plug-in groove 254 to connect the rotating shaft 24 with the rotating wheel 22.

[0042] The end of the insertion shaft 251 is truncated into a cone shape, and the surface of the plug-in block 253 at the joint is matched with the insertion shaft 251 .

[0043] When it is necessary to connect the rotating shaft 24 with the corresponding rotating wheel 22, the insertion shaft 251 moves toward the rotating shaft 24. Since the end of the insertion shaft 251 is truncated cone-shaped and the surface of the plug-in block 253 matches the insertion shaft 251, the insertion shaft 251 pushes the multiple plug-in blocks 253 to move toward the outside of the rotating shaft 24. The first spring 252 is compressed accordingly until the plug-in block 253 is in the corresponding plug-in groove 254. The rotating shaft 24 is then connected to the rotating wheel 22 to rotate it opposite to the feeding direction.

[0044] The provided connecting member 25 can connect the rotating shaft 24 with the corresponding rotating wheel 22, so that the rotating wheel 22 can change the working state of the rubber stabilizing layer 23 as the rotating shaft 24 rotates, thereby realizing the reverse pulling of the cable.

[0045] Figure 1 , Figure 2 and Figure 6 In the straightening assembly, the straightening assembly also includes two oppositely moving members 26, one of which pushes the two pulling clamps 21 to move toward or in the opposite direction to complete the cable clamping or releasing work, and the other of which pushes the two mounting seats 28 to move toward or in the opposite direction. The two mounting seats 28 move toward each other so that the two rubber stabilizing layers 23 are squeezed against each other, increasing the friction with the cable to improve the cable straightening force.

[0046] The oppositely moving member 26 includes a mounting block 261 and a screw rod 262 rotatably inserted in the mounting block 261, one end of the screw rod 262 is connected to an external driving member, and the external driving member is a forward and reverse driving motor. The two ends of the screw rod 262 are provided with threads arranged in opposite directions, and the threaded surfaces at the two ends of the screw rod 262 are sleeved with sliders 263, and the two sliders 263 are fixedly connected to the corresponding pulling clamps 21 or the mounting seats 28.

[0047] After the cable is pulled to a specific position, the external driving member drives the screw rod 262 to rotate. Since threads are arranged in opposite directions at both ends of the screw rod 262, and sliders 263 are sleeved on the threaded surfaces at both ends of the screw rod 262, the two sliders 263 move toward each other to move the mounting seat 28, and the rotating shaft 24 drives the rotating wheel 22 and the rubber stabilizing layer 23 to move. The two rubber stabilizing layers 23 squeeze each other and deform, increasing the friction with the cable, and increasing the force to straighten the cable when the rotating wheel 22 drives the rubber stabilizing layer 23 to rotate.

[0048] The disposed moving member 26 can move the two rotating shafts 24 toward each other through the mounting seat 28, so that the two rubber stabilizing layers 23 squeeze each other and deform, thereby increasing the friction with the cable. When the rotating wheel 22 drives the rubber stabilizing layer 23 to rotate, the straightening force on the cable is increased, thereby preventing the cable from sliding due to a smooth surface and being unable to be straightened.

[0049] Figure 1-Figure 5 In the figure, the connecting member 25 also includes a second spring 271 and a pushing rod 272 with an inclined protrusion, one end of the pushing rod 272 is connected to the external driving mechanism or the mounting block 261 of the pulling clamp 21, the second spring 271 is sleeved on the surface of the insertion shaft 251, and the two ends of the second spring 271 are respectively fixedly connected to the pushing rod 272 and the rotating shaft 24, the pushing rod 272 moves in the feeding direction so that the rotating ball 273 is pushed by the inclined protrusion of the pushing rod 272 to drive the insertion shaft 251 to move toward the rotating shaft 24.

[0050] A rotating ball 273 is disposed on one side of the push rod 272 . The rotating ball 273 is rotatably inserted into the rotating shaft 24 . The rotating ball 273 converts the sliding friction between the push rod 272 and the rotating shaft 24 into rolling friction.

[0051] During the movement of the mounting block 261 of the pulling clamp 21 or under the pull of an external driving mechanism, the pushing rod 272 moves and causes the rotating ball 273 to rotate. After the rotating ball 273 passes the inclined protrusion position of the pushing rod 272, the rotating ball 273 moves along the inclined protrusion surface of the pushing rod 272 to move the insertion shaft 251 toward the rotating shaft 24, and the second spring 271 is compressed accordingly. The second spring 271 stores the deformation capacity to provide power for the reset of the insertion shaft 251.

[0052] The external driving mechanism or the movable mounting block 261 can drive the push rod 272 to move, and the rotating ball 273 moves along the inclined protruding surface of the push rod 272 to move the insertion shaft 251 toward the rotating shaft 24, thereby providing power for the movement of the connecting member 25.

[0053] Figure 1-Figure 3 In the embodiment, a working motor 29 with a reduction device is disposed on one side of the mounting seat 28 , and an output end of the working motor 29 is fixedly connected to the rotating shaft 24 .

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
