The cord is usually wrapped inside the tire and combined with other layers (such as the tread layer and the sidewall layer) to form the overall structure of the tire. The cord inside the car tire usually needs to be cut during the production process to meet the size and shape requirements of different parts of the tire. The multi-knife longitudinal cutting machine is a commonly used mechanical cutting equipment used to cut the cord longitudinally.

[0024] In this embodiment, when in use, the driving motor 402, the circular electromagnet 409, the second forward and reverse motor 503, the third forward and reverse motor 504, the arc electromagnet 518, the first forward and reverse motor 602, the laser rangefinder 608, the hydraulic rod 613 and the PLC controller 2 are electrically connected, and a plurality of positioning rings 410 are provided on the outer surface of the hob shaft 403, and each two positioning rings 410 form a group. A plurality of disc cutters 404 are placed between each group of positioning rings 410, and the disc cutters 404 are pre-positioned, and the connecting groove 414 is aligned with the top of the plurality of clamping rods 413. The two arc electromagnets 518 are respectively positive and negative. The arc magnet 516 corresponding to the positive arc electromagnet 518 is the positive pole, and the arc magnet 516 corresponding to the negative arc electromagnet 518 is the negative pole. When the two arc electromagnets 518 are simultaneously started and energized by the PLC controller 2, repulsive magnetism will be generated at this time, pushing the two arc magnets 516 moves in the opposite direction and pushes the two clamping strips 512 to pass through the corresponding movable holes 514 and enter the clamping slot 513, and the rotating wheel 509 is limited to the outer surface of the fixed shaft 508 by the clamping strip 512. At this time, the bottom end of the clamping rod 413 is located at the deepest part inside the inclined groove 510, and then the second forward and reverse motor 503 is started. The rotation of the output end of the second forward and reverse motor 503 drives the active leather wheel 505, the belt 506 and the driven leather wheel 507 to rotate in turn, and drives the fixed shaft 508 to rotate inside the hob shaft 403, and further drives the two clamping strips 512 and multiple rotating wheels 509 to rotate, so that the bottom end of the clamping rod 413 slides along the inclined groove 510.

The rotation of the output end of the third forward and reverse motor 504 drives the rotating rod 511 to rotate, and drives the two arc-shaped fixed frames 517 to rotate, so that the two arc-shaped electromagnets 518 exchange positions. At this time, the positive arc-shaped electromagnet 518 corresponds to the negative arc-shaped magnet 516, and the negative arc-shaped electromagnet 518 corresponds to the positive arc-shaped magnet 516. The two arc-shaped electromagnets 518 are started again, and magnetic attraction of opposite poles is generated, so that the two arc-shaped magnets 516 move relative to each other. The two clamping strips 512 are pulled out of the clamping slots 513 to reset, so that the subsequent clamping rod 413 drives the rotating wheel 509 to rotate on the outer surface of the fixed shaft 508, and the curtain cloth is unwound through the unwinding device, and then the curtain cloth passes through the disc knife 404 and the slitting plate 3, and the slit curtain cloth is rolled up through the traction device and the winding device. After the installation of the disc knife 404 is completed through the connecting component 5, the driving motor 402 is started to drive the multiple disc knives 404 to rotate, and the curtain cloth on the slitting plate 3 is longitudinally cut. When the disc knife 404 rotates, the internal structure of the annular groove 407 and the clamping rod 413 are driven to rotate together. The bottom end of the clamping rod 413 contacts the inner wall of the inclined groove 510. The rotation of the clamping rod 413 drives the rotating wheel 509 to rotate on the outer surface of the fixed shaft 508, which does not affect the normal rotation of the disc knife 404. When the spacing of the disc knife 404 needs to be adjusted, the slitting component 4 is paused, and the curtain cloth on the slitting plate 3 is adjusted according to the adjustment. Figure 4As shown, the multiple first adjustment clamps 610 and the middle second adjustment clamp 621 correspond to the positions of the multiple disc knives 404 below. The two symmetrical first adjustment clamps 610 in the middle are the first group, and the symmetrical first adjustment clamps 610 on both sides are the second group. The hydraulic rod 613 corresponding to the first group of first adjustment clamps 610 is started to push the front adjustment plate 614 to move downward, and push the first group of first adjustment clamps 610 and the second adjustment clamp 621 to move downward, and at the same time pull the telescopic rod 605 to unfold, and will drive the L-shaped bar 612 to move downward, and further drive the compensation block 619 to move downward to the inside of one of the detection blocks 606. The outer surface of one side of the compensation block 619 is flush with the outer surface of the detection block 606. When the hydraulic rod 613 is paused, the first The first group of first adjusting clamps 610 and the second adjusting clamps 621 are just put on the disc cutters 404 at the corresponding positions, and then the first forward and reverse motor 602 is started. The rotation of the output end of the first forward and reverse motor 602 drives the bidirectional screw rod 603 to rotate, and at the same time drives the first adjusting clamps 610 on the left and right sides to move relatively. The two disc cutters 404 are driven to move relatively through the first group of first adjusting clamps 610, and the L-shaped bar 612 and the compensation block 619 are driven to move together. When the disc cutter 404 moves, it will drive the clamping rod 413 to move in the sliding hole 406, the moving plate 412 to move on the outer surface of the support rod 408, and the rotating wheel 509 to move on the outer surface of the fixed shaft 508. The laser rangefinder 608 is started in advance to detect the distance between it and the compensation block 619 (that is, to detect and detect The distance between the measuring block 606 is measured), and the detected distance data is transmitted to the PLC controller 2 in the form of an electrical signal. The target parameters are set in advance inside the PLC controller 2. The PLC controller 2 will identify and compare according to the received distance data. When the distance data matches the set expected value, the PLC controller 2 will control the first forward and reverse motor 602 to pause, and start the corresponding hydraulic rod 613 to pull the adjustment plate 614 and the first group of first adjustment clamps 610 to reset upward, and drive the L-shaped bar 612 and the compensation block 619 to move upward, so that the detection hole 620 is unblocked, and then the PLC controller 2 starts the first forward and reverse motor 602 again to make its output end rotate in the opposite direction, driving the two groups of first adjustment clamps 610 to move in the opposite direction to reset. After the adjustment is completed, the control unit 200 will pause, and then control the hydraulic rod 613 corresponding to the second group of first adjustment clamps 610, which will push the adjustment plate 614 and the second group of first adjustment clamps 610 to move downward and sleeve on the disc cutters 404 on both sides. Then the first forward and reverse motor 602 is started, and the two groups of first adjustment clamps 610 are driven to move again through the positive rotation of its output end. At this time, the laser of the laser rangefinder 608 passes through the detection hole 620 to the leftmost detection block 606 to detect the distance between the detection block 606 and the leftmost detection block 606. When the distance meets the set expected value, the PLC controller 2 will turn off the first forward and reverse motor 602 again, and start the hydraulic rod 613 to pull the second group of first adjustment clamps 610 upward to reset. Under the action of the adjustment component 6,Thus, the effect of automatically adjusting the distance between the blades can be achieved, which can adapt to the cutting of different specifications of cord fabrics, save time and manpower, reduce errors, and improve accuracy. It solves the problem that when a multi-blade longitudinal cutting machine needs to cut cord fabrics of different specifications, it needs to adjust the distance between the blades by loosening and tightening the bolts again, which takes a lot of time and manpower, and is also easy to cause inaccurate adjustment of the blade spacing, affecting the cutting quality and poor work efficiency.

[0028] In this embodiment, when in use, when the slitting assembly 4 is closed, the hob shaft 403, the disc knife 404 and the rotating wheel 509 are rotated and reset, so that the card slot 513 is reset and relative to the position of the rotating card strip 512, the arc electromagnet 518 is closed and the third forward and reverse motor 504 is started again. At this time, the output end of the third forward and reverse motor 504 rotates in the reverse direction, driving the rotating rod 511 to rotate in the reverse direction, so that the two arc electromagnets 518 rotate in the reverse direction and reset, so that the positive arc electromagnet 518 corresponds to the positive arc magnet 516, and the negative arc electromagnet 518 corresponds to the negative arc The magnet 516 starts the arc electromagnet 518 again, generates repulsive magnetism, pushes the card strip 512 into the card slot 513 again, connects the rotating wheel 509 and the fixed shaft 508 together again, starts the second forward and reverse motor 503 again, and its output end rotates in the opposite direction, driving the active leather wheel 505, the belt 506 and the driven leather wheel 507 to rotate in the opposite direction, so that the fixed shaft 508 drives the multiple rotating wheels 509 to rotate in the opposite direction, and further rotates the card rod 413 to the deepest part of the inclined groove 510. Under the action of the gravity ball 415, it is convenient for the card rod 413 to better move along the inclined groove 510. The inner wall of the inclined groove 510 moves so that the top of the clamping rod 413 leaves the inside of the connecting groove 414, and then the bolts at the connection between the drive motor 402 and the hob shaft 403 are removed, and the connecting bolts of one of the support frames 401 are removed, so that the support frame 401 and the drive motor 402 can be separated from the hob shaft 403, and finally the disc cutter 404 is slid out from the outer surface of the hob shaft 403, and the hob shaft 403 can be removed for replacement. The circular electromagnet 409 has the same magnetic property as the circular electromagnet 416. Before installing the circular cutter 404 through the connecting component 5, start the circular electromagnet The magnet 409 generates repulsive magnetism, pushing the multiple circular magnets 416 to move upward, and driving the fixed plate 417 to move upward, so that the insertion rod 418 is inserted into the embedded groove 411 to limit the movable plate 412, and better limit the clamping rod 413 inside the sliding hole 406 to prevent the subsequent clamping rod 413 from accidentally shifting when moving upward, affecting the limiting of the disc knife 404. After the installation of the disc knife 404 is completed through the connecting component 5, the circular electromagnet 409 is turned off, and the insertion rod 418 leaves the embedded groove 411 under the action of gravity.

[0029] The effect and working principle achieved by the entire mechanism are as follows: the two arc-shaped electromagnets 518 are started and energized to generate repulsive magnetism, which pushes the two arc-shaped magnets 516 to move in opposite directions, and pushes the two clamping strips 512 to pass through the corresponding movable holes 514 into the clamping slots 513, and the second forward and reverse motor 503 is started. The rotation of the output end of the second forward and reverse motor 503 drives the active pulley 505, the belt 506 and the driven pulley 507 to rotate in turn, and drives the fixed shaft 508 to rotate inside the roller shaft 403, and further drives the two clamping strips 512 and multiple rotating wheels 509 to rotate, so that the bottom end of the clamping rod 413 moves from the deepest part inside the inclined groove 510 to the shallowest part, and at the same time, the top end of the clamping rod 413 enters the connecting groove 414, limiting the disc cutter 404 in the roller shaft 403. The outer surface of the knife shaft 403, then close the two arc-shaped electromagnets 518, and start the third forward and reverse motor 504. The rotation of the output end of the third forward and reverse motor 504 drives the rotating rod 511 to rotate, and will drive the two arc-shaped fixed frames 517 to rotate, so that the two arc-shaped electromagnets 518 exchange positions, and start the two arc-shaped electromagnets 518 again. At this time, magnetic attraction is generated, so that the two arc-shaped magnets 516 move relative to each other, and pull the two card strips 512 out of the card slot 513 to reset, so that the subsequent card rod 413 drives the rotating wheel 509 to rotate on the outer surface of the fixed shaft 508, and starts the driving motor 402, which drives the multiple disc knives 404 to rotate, and the curtain fabric on the slitting plate 3 is longitudinally cut. The rotation of the disc knife 404 will drive the annular groove 40 The internal structure of 7 rotates together with the clamping rod 413, and the bottom end of the clamping rod 413 contacts the inner wall of the inclined groove 510. The rotation of the clamping rod 413 drives the rotating wheel 509 to rotate on the outer surface of the fixed shaft 508, which does not affect the normal rotation of the disc cutter 404. The two first adjustment clamps 610 symmetrical in the middle are the first group, and the first adjustment clamps 610 symmetrical on both sides are the second group. Start one of the hydraulic rods 613 to push the front adjustment plate 614 to move downward, and push the first group of first adjustment clamps 610 and the second adjustment clamps 621 to move downward, and at the same time pull the telescopic rod 605 to expand, and drive the L-shaped bar 612 to move downward, and further drive the compensation block 619 to move downward to the inside of one of the detection blocks 606, and the outer surface of one side of the compensation block 619 contacts the inner wall of the inclined groove 510. The outer surfaces of the detection block 606 are flush with each other. When the hydraulic rod 613 is suspended, the first group of first adjustment clamps 610 and the second adjustment clamps 621 are just put on the disc cutter 404 at the corresponding position, and then the first forward and reverse motor 602 is started to drive the bidirectional screw rod 603 to rotate, and at the same time drive multiple first adjustment clamps 610 to move relatively. The two disc cutters 404 are driven to move relatively through the first group of first adjustment clamps 610, and the L-shaped bar 612 and the compensation block 619 are driven to move together. The laser rangefinder 608 is started in advance to detect the distance between the compensation block 619 (that is, the distance between the detection block 606), and the detected distance data is transmitted to the PLC controller 2 in the form of an electrical signal. The target parameters are set in advance inside the PLC controller 2.The PLC controller 2 will identify and compare the received distance data. When the distance data matches the set expected value, the PLC controller 2 will control the first forward and reverse motor 602 to pause, and start the corresponding hydraulic rod 613 to pull the adjustment plate 614 and the first group of first adjustment clamps 610 to reset upward, and drive the L-shaped bar 612 and the compensation block 619 to move upward, so that the detection hole 620 is unblocked, and then start the first forward and reverse motor 602 again to make its output end rotate in the opposite direction, drive the two groups of first adjustment clamps 610 to move in the opposite direction and reset and pause, and then control the hydraulic rod 613 corresponding to the second group of first adjustment clamps 610, which will push the adjustment plate 614 and the second group of first adjustment clamps 610 to move downward, and the sleeve On the disc cutters 404 on both sides, the first forward and reverse motor 602 is then started, and through the forward rotation of its output end, the two groups of first adjusting clamps 610 are driven to move again. At this time, the laser of the laser rangefinder 608 passes through the detection hole 620 to the detection block 606 on the far left, and detects the distance between the detection block 606 on the far left. When the distance meets the set expected value, the PLC controller 2 will turn off the first forward and reverse motor 602 again, and start the hydraulic rod 613 to pull the second group of first adjusting clamps 610 to move upward and reset. Under the action of the adjustment component 6, the effect of automatically adjusting the blade distance is achieved to adapt to the cutting of curtains of different specifications, save time and manpower, reduce errors, and improve accuracy. At the same time, the two The hydraulic rod 613 moves downward, pushing the two adjustment plates 614 to move downward, and pushing the first adjustment clamps 610 and the second adjustment clamps 621 to move downward together, so that the outer surface of the disc knife 404 is embedded in the grinding block 615, and the disc knife 404 is ground to make its edge sharper and better for cutting. When the cutting assembly 4 is closed, the hob shaft 403, the disc knife 404 and the rotating wheel 509 are rotated and reset, so that the card slot 513 is reset to the position relative to the card strip 512 after rotation, the arc electromagnet 518 is closed and the third forward and reverse motor 504 is started again. At this time, the output end of the third forward and reverse motor 504 rotates in the opposite direction, driving the rotating rod 511 to rotate in the opposite direction, so that the two arc electromagnets 518 rotate in the opposite direction. Reset, start the arc-shaped electromagnet 518 again, generate repulsive magnetism, push the card strip 512 into the card slot 513 again, start the second forward and reverse motor 503 again, and its output end rotates in the opposite direction, so that the fixed shaft 508 drives the multiple wheels 509 to rotate in the opposite direction, and further rotates the card rod 413 to the deepest part of the inclined groove 510. At the same time, the top of the card rod 413 leaves the inside of the connecting groove 414, and then remove the bolts at the connection between the drive motor 402 and the hob shaft 403, and remove the connecting bolts of one of the support frames 401, so that the support frame 401 and the drive motor 402 can be separated from the hob shaft 403, and finally the disc cutter 404 can be slid out from the outer surface of the hob shaft 403, and the hob shaft 403 can be removed for replacement.
