[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 , Figure 2 , Figure 5 and Fig. 9 As shown, the embodiment of the present application discloses a shaftless winder, comprising a winding frame 1, on which a winding mechanism 2 is arranged, a guide cutting frame 3 is arranged on one side of the winding frame 1, and a guide roller assembly 4 and a cutting assembly 5 are arranged in sequence on the guide cutting frame 3 along the product movement direction;

[0035] The cutting assembly 5 includes a mounting frame 501, a first guide rail 502 is arranged on the guide cutting frame 3, the bottom of the mounting frame 501 is slidably connected to the first guide rail 502 through a slider, and also includes a mounting frame driving mechanism 503 for driving the mounting frame 501 to move along the first guide rail 502, a first pressing roller 504 and a first pressing roller driving mechanism 505 for driving the first pressing roller 504 to move toward the winding mechanism 2 are arranged on the mounting frame 501, and also includes a winding ironing knife assembly 51 and a serrated knife assembly 52 arranged above the first pressing roller 504;

[0036] The winding mechanism 2 includes a winding support frame 201, the winding support frame 201 is rotatably connected to the winding frame 1, the winding frame 1 is provided with a rotating drive mechanism for driving the winding support frame 201 to perform a rotational motion, and the winding support frame 201 is symmetrically provided with a first winding assembly 21 and a second winding assembly 22 with the same mechanism on both sides;

[0037] The first winding assembly 21 and the second winding assembly 22 are both provided with a second pressure roller 231 and a third pressure roller of the same structure on the opposite inner sides thereof, and further include a second pressure roller driving mechanism for driving the second pressure roller 231 to move toward the first winding assembly 21 and a third pressure roller driving mechanism for driving the third pressure roller to move toward the second winding assembly 22;

[0038] The first empty roll is used for mounting on the first winding assembly 21 and the second empty roll is used for mounting on the second winding assembly. The surfaces of the first empty roll and the second empty roll are provided with projections at intervals in the axial direction.

[0039] In the above structure, by arranging protrusions at intervals along the axial direction on the surfaces of the first empty roll and the second empty roll, the air in the innermost layer of the roll can be discharged, thereby ensuring the flatness of the roll.

[0040] When working specifically, if the first empty roll is used, the first empty roll is clamped on the winding assembly, and the product to be wound is wound on the empty roll after passing through the guide roller assembly 4. Under the drive of the cone head rotation drive mechanism 216, the product to be wound is continuously wound on the first empty roll. At the same time, the rotating swing arm drive mechanism 235 drives the swing arm to rotate, so that during the winding process of the first empty roll, the second pressure roller 231 is close to the product wound on the first empty roll. When the first empty roll is wound, a new roll needs to be replaced. The new second empty roll is clamped in the second winding assembly 22, and the rotating drive mechanism drives the winding support frame 201 to rotate 180 degrees, so that the first winding assembly 21 and the second roll exchange positions. At the same time, the cutting assembly 5 is continuously retreated under the drive of the mounting frame drive mechanism 503, so that the first pressure roller 504 is 30-50mm away from the product on the empty roll. When the empty roll completes the winding operation, the winding ironing knife assembly 51 or the serrated knife assembly 52 moves forward to cut the product.

[0041] It should be explained that in order to ensure that the first pressing roller 504 is 30-50 mm away from the product on the first empty roll, a distance sensor can be installed for distance feedback, or program control can be used in advance to enable the mounting frame 501 to achieve precise movement.

[0042] It should be explained that the distance between the first pressing roller 504 and the product on the empty roll can be 30 mm, 40 mm, 50 mm, etc., and the specific distance can be determined according to the tension of the product.

[0043] In the present invention, the first pressing roller 504 is arranged so that during the winding process, the first pressing roller 504 is always close to the product on the material roll, thereby playing a role in eliminating bubbles and ensuring the flatness of the product. At the same time, the second pressing roller and the first pressing roller cooperate with the arrangement of the protrusions on the second empty material roll, so that when the material roll is cut, the bubbles on the product and the empty material roll can be discharged from the gap between the two adjacent protrusions when the product is wound on the new empty material roll through extrusion, thereby making the bottom wrinkles of the product better and thus ensuring the flatness of the product. In addition, during the continuous winding process of the product, the second pressing roller 231 can squeeze out the air wound in during the winding process, thereby making the coil winding tighter and eliminating bubbles in the wound coil, thereby making the product flatter. At the same time, the device is respectively provided with a winding ironing knife assembly 51 and a serrated knife assembly 52, so that two different cutting modes can be used for different products, thereby ensuring the flatness of product cutting.

[0044] In this embodiment, Figure 5As shown, the first winding assembly 21 includes a first reel frame 211 and a second reel frame 212, the winding support frame 201 is provided with a screw drive mechanism 213 for driving the first reel frame 211 and the second reel frame 212 to make relative movement or opposite movement, the first reel frame 211 is provided with a first transmission cone head 214, the first transmission cone head 214 and the first reel frame 211 are rotatably connected through a bearing, the second reel frame 212 is provided with a second transmission cone head 215, the second transmission cone head 215 and the second reel frame 212 are rotatably connected through a bearing, and also includes a cone head rotation driving mechanism 216 for driving the second transmission cone head 215 to rotate;

[0045] Specifically, during operation, the first empty material roll is clamped in the first winding assembly 21, and the product to be wound around the first empty material roll after passing through the guide roller assembly 4. Driven by the cone head rotation drive mechanism 216, the product to be wound around the first empty material roll continuously, and the cutting assembly 5 moves forward driven by the mounting frame drive mechanism 503. The winding ironing knife assembly 51 or the serrated knife assembly 52 moves forward to cut the product, and the product is rewound around the second empty material roll. After the cutting and switching of the rolls are completed, the winding operation is continued with the second empty material roll.

[0046] The design of the above structure can realize the roll changing operation without stopping the machine, thereby improving the winding efficiency.

[0047] In this embodiment, Figure 7 As shown, the second pressure roller driving mechanism includes a bearing mounting plate 232 fixed on the winding support frame 201, and also includes a rotating rod 233, the two ends of the rotating rod 233 are rotatably connected to the bearing mounting plate 232 through bearings, a rotating swing arm 234 is installed on the rotating rod 233, and the winding support frame 201 is provided with a rotating swing arm driving mechanism 235 for driving the rotating swing arm 234 to perform rotational motion, and the bottom end of the rotating swing arm 234 is provided with a guide roller mounting arm 236, and the second pressure roller 231 is installed on the guide roller mounting arm 236.

[0048] Specifically, when the first empty roll is rotating and winding, the rotary swing arm driving mechanism 235 drives the swing arm to rotate, so that during the winding process of the first empty roll, the second pressing roller 231 is in close contact with the product wound on the first empty roll.

[0049] The second pressing roller 231 can be arranged to squeeze out the air wound into the coil during the coiling process, so that the coil is wound more tightly and at the same time, there are no bubbles in the wound coil, thereby making the product smoother.

[0050] In this embodiment, Figure 2 and Figure 3As shown, the serrated knife assembly 52 includes a serrated blade 521 and a blade driving mechanism 522 for driving the serrated blade 521 to extend forward;

[0051] The winding ironing knife assembly 51 includes a mounting tube 511, and the two ends of the mounting tube 511 are respectively provided with a first guide rail mounting plate 512 and a second guide rail mounting plate, and also includes a first driving cylinder 513 and a second driving cylinder for respectively driving the first guide rail mounting plate 512 and the second guide rail mounting plate to extend forward;

[0052] The first guide rail mounting plate 512 is provided with a second guide rail 514, and the second guide rail 514 is provided with a first stud 515 at one end away from the second guide rail mounting plate, and further includes a first heating wire mounting seat 516, the first heating wire mounting seat 516 is slidably connected to the second guide rail 514 via a second slider 517, and a first spring 518 is provided between the first heating wire mounting seat 516 and the first stud 515;

[0053] The second guide rail mounting plate is provided with a third guide rail, the third guide rail is provided with a second stud at one end away from the first guide rail mounting plate 512, and further comprises a second heating wire mounting seat, the second heating wire mounting seat is slidably connected to the third guide rail via a third slider, and a second spring is provided between the second heating wire mounting seat and the second stud;

[0054] It also includes a heating wire 519 , two ends of which are mounted on the first heating wire mounting seat 516 and the second heating wire mounting seat respectively.

[0055] Specifically, due to the different materials being rolled up, according to the characteristics of the materials, some materials need to be cut using a serrated blade 521, and some materials need to be cut using hot blanching. When the product is cut using the cutting method, the blade drive mechanism 522 drives the serrated blade 521 to extend forward, so that the serrated blade 521 is inserted into the product to cut the product. When the product is cut using hot blanching, the first drive cylinder 513 and the second drive cylinder simultaneously drive the first guide rail mounting plate 512 and the second guide rail mounting plate to move forward, so that the heating wire 519 contacts the product to cut the product.

[0056] In the above-mentioned winding and ironing knife assembly 51, the design of the first heating wire mounting seat 516, the first stud 515, the first spring 518, the second heating wire mounting seat, the second stud and the second spring makes both ends of the heating wire 519 in a tensioned state. At the same time, in this structure, the arrangement of the first guide rail 502, the first slider, the second guide rail 514 and the second slider 517 allows the first heating wire mounting seat 516 and the second heating wire mounting seat to have room for relative sliding, so that the heating wire 519 will not break due to excessive tension, thereby ensuring the straightness of the heating wire 519 when ironing the product.

[0057] In this embodiment, Figure 8 As shown, a winding turntable 601 is provided on one side of the winding support frame 201, and the other side of the winding support frame 201 is rotatably connected to the winding frame 1 through a connecting shaft 602 and a bearing. The winding turntable 601 is circumferentially provided with driving teeth 603, and the winding frame 1 is also provided with a driving motor 604. A gear is provided on the output shaft of the driving motor 604, and the gear is meshed with the driving gear 603.

[0058] Specifically, when the first empty material roll is wound up and needs to be replaced with a new material roll, the new second empty material roll is clamped in the second winding assembly 22, and the driving motor 604 drives the gear wheel 603 to rotate. Since the gear is engaged with the driving gear 603, the turning turntable 601 is driven to rotate 180 degrees, thereby realizing the exchange of positions between the first winding assembly 21 and the second winding assembly, and realizing non-stop loading and unloading operations.

[0059] The arrangement of the above structure can realize the position exchange of the two winding components, thereby realizing the loading and unloading operation without stopping the machine, thereby ensuring the winding efficiency of the device.

[0060] The present invention also discloses a shaftless winding method, which uses the shaftless winding machine described above, specifically: the first empty material roll is clamped in the first winding component 21, the product to be wound is wound on the first empty material roll after passing through the guide roller component 4, and the product to be wound is continuously wound on the first empty material roll under the drive of the cone head rotation drive mechanism 216. At the same time, the cutting component 5 is continuously retreated under the drive of the mounting frame drive mechanism 503, so that the first pressure roller 504 is 30-50mm away from the product on the first empty material roll. At the same time, the rotating swing arm drive mechanism 235 drives the swing arm to rotate, so that during the process of winding the first empty material roll, the second pressure roller 231 is close to the product wound on the first empty material roll. When the first empty roll is wound up and needs to be replaced with a new roll, the new second empty roll is clamped in the second winding assembly 22, and the rotary drive mechanism drives the winding support frame 201 to rotate 180 degrees, so that the first winding assembly 21 and the second winding assembly are exchanged, and the first pressure roller drive mechanism 505 drives the first pressure roller 504 to move forward, so that the distance between the first pressure roller 504 and the second empty roll is 5-10mm, and then the cutting assembly 5 moves forward under the drive of the mounting frame drive mechanism 503, and the winding ironing knife assembly 51 or the serrated knife assembly 52 moves forward to cut the product, and the product is rewound on the second empty roll. After the cutting and switching of rolls are completed, the winding operation continues with the second empty roll.

[0061] During the winding process of the present method, the first pressing roller 504 is always close to the product on the material roll, so as to eliminate bubbles. At the same time, during the cutting operation, the first pressing roller 504 moves forward, so that when the product is wound on the new material roll, the bottom wrinkles and lines of the product can be reduced, making the product smoother.

[0062] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention.

Under the drive of the cone head rotation drive mechanism (216), the product to be wound is continuously wound on the first empty material roll. At the same time, the cutting assembly (5) is continuously retreated under the drive of the mounting frame drive mechanism (503), so that the first pressure roller (504) is 30-50 mm away from the product on the first empty material roll. At the same time, the swing arm drive mechanism (235) drives the swing arm to rotate, so that during the process of winding the first empty material roll, the second pressure roller (231) is closely attached to the product wound on the first empty material roll. When the winding of the first empty material roll is completed, a new material roll needs to be replaced. When the second empty roll is clamped in the second winding assembly (22), the rotary drive mechanism drives the winding support frame (201) to rotate 180 degrees, so that the first winding assembly (21) and the second winding assembly (21) exchange positions, and the first pressure roller drive mechanism (505) drives the first pressure roller (504) to move forward, so that the distance between the first pressure roller (504) and the second empty roll is 5-10 mm. Then the cutting assembly (5) moves forward under the drive of the mounting frame drive mechanism (503), and the winding ironing knife assembly (51) or the serrated knife assembly (52) moves forward to cut the product, and the product is rewound on the second empty roll. After the cutting and winding are completed, the winding operation continues with the second empty roll.
