The two linear guide rails 420 on the same wall panel 410 are cross-arranged, and a cross-reversing assembly 470 is provided between the two cross-arranged linear guide rails 420.

[0033] When the working coil on the unwinding and rewinding mechanism for unwinding is empty, the cross reversing component 470 will be connected to the linear guide rail 420 corresponding to the new coil, and the driving component 460 will drive the corresponding moving frame 430 to slide along the linear guide rail 420 and approach the new coil. Then, the pressing belt component 440 on the moving frame 430 presses the working material belt on the working coil onto the new coil, so that the material head of the working material belt is bonded to the material head on the new coil. Then, the cutting belt component 450 cuts the working material belt. Finally, the cutting belt component 450 and the pressing belt component 440 are reset, and the driving component 460 drives the moving frame 430 to slide along the linear guide rail 420 and away from the new coil.

[0034] When the working coil on the rewinding and unwinding mechanism for winding is full, the cross reversing assembly 470 will be connected with the linear guide 420 corresponding to the new empty barrel, and the driving assembly 460 will drive the corresponding moving frame 430 to slide along the linear guide 420 and approach the empty barrel, so that the belt pressing assembly 440 on the moving frame 430 will push the working material belt to one side of the empty barrel, then the belt pressing assembly 440 will press the working material belt against the empty barrel, and then the belt cutting assembly 450 will cut the working material belt. , so that the material head of the working material tape is adhered to the outer periphery of the empty barrel. Finally, the tape cutting assembly 450 and the tape pressing assembly 440 are reset, and the driving assembly 460 drives the movable frame 430 to slide along the linear guide rail 420 and away from the empty barrel. The empty barrel is wound normally, and the chuck 200 withdraws from the inner ring of the barrel of the old coil. The AGV trolley takes away the old coil and puts on a new empty barrel. The chuck 200 extends into the inner ring of the new empty barrel to realize online roll changing, thereby avoiding excessive equipment downtime and improving production efficiency.

[0035] Reference Figure 8 and Fig. 9 In some preferred embodiments, the driving assembly 460 includes a motor 461, a gear 462 arranged on the main shaft of the motor 461, a fixed rack 463 is arranged on one side of the linear guide 420, the length direction of the fixed rack 463 extends along the length direction of the linear guide 420, the gear 462 is engaged with the fixed rack 463, and the motor 461 is fixed on the moving frame 430.

[0036] Specifically, the motor 461 drives the gear 462 to rotate, and the gear 462 engages with the fixed rack 463 to convert the rotational motion of the motor 461 into the linear motion of the moving frame 430. The moving frame 430 drives the belt pressing assembly 440 and the belt cutting assembly 450 to move as a whole along the length direction of the linear guide 420. The transmission accuracy between the gear 462 and the fixed rack 463 is high, so that the moving distance of the moving frame 430 can be accurately controlled, thereby improving the stability of the moving frame 430 during movement.

[0037] In some preferred embodiments, the two cross-arranged linear guides 420 are perpendicular to each other, and a square first notch is formed at the intersection of the two linear guides 420. Each linear guide 420 and the fixed rack 463 are divided into two sections. A second notch corresponding to the first notch is provided on the wall panel 410. The cross-reversing assembly 470 is provided on the wall panel 410, and the cross-reversing assembly 470 corresponds to the second notch. The first notch and the second notch can cooperate with the cross-reversing assembly 470 to facilitate the installation of the cross-reversing assembly 470.

[0038] Reference Figure 3 and Figure 6Furthermore, the cross-reversing assembly 470 includes a splicing plate 471, a splicing guide rail 472 and a splicing rack 473 arranged on the splicing plate 471, a first rotating cylinder 474 for driving the splicing plate 471 to rotate, and a first telescopic cylinder 475 for driving the splicing plate 471 to extend or retract. The splicing plate 471 corresponds to the second notch, and the first telescopic cylinder 475 is installed on the side of the wall panel 410 away from the linear guide rail 420 through the mounting frame 476.

[0039] It can be understood that when one of the driving components 460 drives the corresponding moving frame 430 to move, the splicing guide rail 472 and the splicing rack 473 on the splicing plate 471 can connect the two discontinuous linear guide rails 420 and the fixed rack 463, so that the moving frame 430 can slide normally along the corresponding linear guide rail 420; when the other driving component 460 drives the corresponding moving frame 430 to move, the first telescopic cylinder 475 drives the splicing plate 471 to extend, and then the first rotating cylinder 474 drives the splicing plate 471 to extend. Rotate 90 degrees to rotate the splicing guide rail 472 and the splicing rack 473 on the splicing plate 471 90 degrees. Then, the first telescopic cylinder 475 drives the splicing plate 471 to retract, so that the splicing guide rail 472 and the splicing rack 473 respectively connect the other two discontinuous linear guide rails 420 and the fixed rack 463. The other movable frame 430 can slide normally along the corresponding linear guide rail 420, thereby realizing the precise switching of the two cross-arranged linear guide rails 420 and ensuring the normal movement of the two different movable frames 430.

[0040] Furthermore, a moving seat 477 is provided at the telescopic end of the first telescopic cylinder 475, the first rotating cylinder 474 is provided on the moving seat 477, the splicing plate 471 is provided at the output end of the first rotating cylinder 474, the first telescopic cylinder 475 drives the moving seat 477 to approach or move away from the wall panel 410, the moving seat 477 drives the first rotating cylinder 474 and the splicing plate 471 to move together, the first rotating cylinder 474 drives the splicing plate 471 to rotate, the overall structure is compact, and the arrangement of the cross-reversing assembly 470 is convenient.

[0041] In some preferred embodiments, the mounting frame 476 includes a cylinder mounting plate 4761 and a plurality of guide columns 4762, the two ends of the plurality of guide columns 4762 are respectively connected to the wall panel 410 and the cylinder mounting plate 4761, the first telescopic cylinder 475 is installed on the cylinder mounting plate 4761, the guide column 4762 and the wall panel 410 are perpendicular to each other, and a plurality of sliding sleeves 4771 are provided on the movable seat 477, and the plurality of sliding sleeves 4771 are respectively sleeved on the outer periphery of the plurality of guide columns 4762.

[0042] It can be understood that when the first telescopic cylinder 475 drives the moving seat 477 to translate, the several sliding sleeves 4771 arranged on the moving seat 477 move along the length direction of the several guide columns 4762 respectively, thereby ensuring that the moving seat 477 translates in a direction perpendicular to the wall panel 410, ensuring that the splicing plate 471 is precisely matched with the second notch on the wall panel 410, and further ensuring that the splicing guide rail 472 and the splicing rack 473 on the splicing plate 471 are precisely connected to the discontinuous linear guide rail 420 and the fixed rack 463 on the wall panel 410.

[0043] Reference Figure 4 , Figure 7 and Figure 8 In some preferred embodiments, the movable frame 430 includes two slides 431 and a connecting beam 432 for connecting the two slides 431. The tape cutting assembly 450 includes a knife seat 451, a cutter 452 installed on the knife seat 451 and a second rotating cylinder 453 for driving the knife seat 451 to swing. The second rotating cylinder 453 is set on one of the slides 431, one end of the knife seat 451 is connected to the output end of the second rotating cylinder 453, and the other end of the knife seat 451 is rotated to be connected to another slide 431 through a belt seat bearing 457. When cutting the tape, the second rotating cylinder 453 drives the knife seat 451 and the cutter 452 to swing together, so that the blade of the cutter 452 is close to the material tape, which can quickly cut the material tape.

[0044] By setting a second rotating cylinder 453 as the power source of the cutter 452, the other end of the knife seat 451 is rotated to be connected to another slide seat 431 through the belt seat bearing 457, so that the force on the cutter 452 is balanced, thereby ensuring that the cutter 452 always remains parallel to the material belt during the cutting process, and the blade of the cutter 452 is in full contact with the material belt in the width direction, thereby ensuring that the material belt can be cut quickly.

[0045] By providing the knife holder 451 , the cutter 452 is mounted on the knife holder 451 by means of fasteners such as bolts, thereby facilitating replacement of the worn cutter 452 .

[0046] Furthermore, the cutting assembly also includes a first swing arm 454, a shield 455 and a second telescopic cylinder 456. The middle part of the first swing arm 454 is rotatably connected to the slide 431, one end of the shield 455 is rotatably connected to one end of the first swing arm 454, the telescopic end of the second telescopic cylinder 456 is hinged to the other end of the first swing arm 454, and the cylinder body of the second telescopic cylinder 456 is hinged on the slide 431. The shield 455 is located on one side of the blade of the cutter 452. The first swing arm 454 is driven to swing by the second telescopic cylinder 456, and the shield 455 is driven to swing along the rotation center of the first swing arm 454, so that the shield 455 can block or stay away from the blade of the cutter 452.

[0047] It can be understood that when it is necessary to cut the tape, the second telescopic cylinder 456 drives the first swing arm 454 to swing so as to drive the shield 455 away from the blade of the cutter 452, so that the blade of the cutter 452 is exposed and faces the material tape, so as to facilitate the cutter 452 to cut the material tape; when the material tape is running normally, the second telescopic cylinder 456 drives the first swing arm 454 to swing in the opposite direction so as to drive the shield 455 to cover the blade of the cutter 452, thereby preventing the material tape from contacting the blade of the cutter 452 and ensuring that the material tape is not damaged.

[0048] Reference Figure 4 , Figure 7 and Figure 8 In some preferred embodiments, the belt pressing assembly 440 includes a pressing roller 441, two second swing arms 442 and two third telescopic cylinders 443, the cylinder bodies of the two third telescopic cylinders 443 are respectively hinged on the two slides 431, the middle parts of the two second swing arms 442 are respectively rotatably connected to the two slides 431, the two ends of the pressing roller 441 are respectively rotatably connected to one end of the two second swing arms 442, and the telescopic ends of the two third telescopic cylinders 443 are respectively hinged to the other ends of the two second swing arms 442.

[0049] It can be understood that before cutting the tape, the two second swing arms 442 are driven to swing simultaneously by the two third telescopic cylinders 443, thereby driving the pressure roller 441 to swing around the rotation center of the second swing arm 442, so that the pressure roller 441 approaches and abuts against the material tape on the coil, thereby being able to press the material tape tightly.

[0050] By providing two third telescopic cylinders 443 as the power source of the pressing roller 441, the force on the pressing roller 441 is balanced, thereby ensuring that the pressing roller 441 always remains parallel to the material belt during the belt pressing process, and the roller surface of the pressing roller 441 is in full contact with the material belt in the width direction, thereby improving the stability during belt pressing.

[0051] In some preferred embodiments, a plurality of rollers 480 are provided on the slide 431 and the wall panel 410, and the rollers 480 are used to support and guide the material belt. Among them, the rollers 480 provided on the wall panel 420 are located on the side of the cross-reversing assembly 470 away from the two chucks 200, thereby ensuring that the material belt avoids other structures on the equipment during the conveying process, ensuring that the material belt can convey normally.
