Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically a coreless fully automatic slitting machine. Background Technology

[0002] In the post-processing of roll materials such as films, paper, and non-woven fabrics, slitting is an essential step. Traditional slitting machines often face the problem of uneven material edges when cutting narrow strips of material for roll change after slitting. This is mainly because at the moment the high-speed rotating circular blade cuts the material edge, the material before and after the cutting point loses its constraint and vibrates or lifts, resulting in burrs, fraying, or wavy deformation on the cut surface, which seriously affects the quality of the product and the flatness of the roll. In existing technologies, although simple pressure rollers or fixed plates are used for limiting, they often cannot provide effective and stable pressure before and after the cutting point at the same time. Especially during the dynamic movement of the cutting process, the limiting effect is poor and it is difficult to meet the actual production needs. Utility Model Content

[0003] The purpose of this invention is to provide a coreless fully automatic slitting machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a coreless fully automatic slitting machine, comprising an unwinding mechanism and a main unit, wherein a winding mechanism is installed on the rear side of the main unit for winding the material, and a slitting mechanism is installed on the main unit for cutting the raw material, the slitting mechanism comprising a fixing plate fixed on the main unit, the slitting mechanism further comprising a crossbar fixed on the main unit, a movable frame for left and right movement provided on the side of the crossbar, a cutting motor fixed on the movable frame, and a cutting circular blade fixed at the output end of the cutting motor for cutting the raw material.

[0005] Preferably, the unwinding mechanism is equipped with a roll of material, and a web-aligning machine is provided at the rear of the unwinding mechanism and at the front of the main unit. Through the above structure, the normal release of the material can be guaranteed, thereby providing a basic guarantee for the normal operation of the device.

[0006] Preferably, the slitting mechanism further includes a support plate fixed on the host machine, and the support plate is located below the front side of the cutting circular blade. The support plate can support the material in front of the cutting circular blade to ensure the normal cutting of subsequent materials.

[0007] Preferably, a lower limit plate fixed to the host is provided on the rear side of the pallet, and an upper limit plate fixed to the host is provided above the lower limit plate. The upper surface of the lower limit plate is flush with the upper surface of the pallet. At the same time, the lower limit plate is located below the rear side of the cutting circular blade. Through the action of the lower limit plate and the upper limit plate, the material can be limited, ensuring the normal material cutting.

[0008] Preferably, a servo motor is also fixed on the crossbar, and a gear is fixed at the output end of the servo motor, and another gear is connected to the crossbar by a bearing. At the same time, a toothed belt is connected between the two gears. Through the above structure, a basic force can be provided to drive the movable frame.

[0009] Preferably, the movable frame is also fixed with a slider, and the slider is slidably connected to the guide rail. The guide rail is fixed to the crossbar, and the slider and the toothed belt are fixed to each other. When the movable frame moves, the sliding guidance between the slider and the guide rail can ensure the stability of the movable frame's movement.

[0010] Preferably, the movable frame is also fixed with a vertical rod, and a pressure plate is fixed at the lower end of the vertical rod. The pressure plate has a sloping structure on both the left and right sides. At the same time, the pressure plate is located above the support plate. The lower end face of the support plate is flush with the lower end face of the upper limit plate. Through the above structure, the material can be flattened and limited, avoiding material warping and affecting the normal cutting process.

[0011] Preferably, the host is also equipped with an air knife assembly, which is located between the slitting mechanism and the straightening machine. The air knife assembly can be used to slit and cut the material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This coreless fully automatic slitting machine perfectly solves the problem of material vibration during cutting by setting limiting structures on the front and rear sides of the cutting circular blade. Specifically, when the cutting circular blade moves to cut, the material on the front side is stably pressed and attached by the cooperation of the pressure plate and the support plate, while the material on the rear side is restricted between the lower limiting plate and the upper limiting plate. This front and rear clamping limiting method ensures that the material will not be displaced or vibrate due to the high-speed rotation and movement of the circular blade at the moment of cutting, thereby making the cut surface of the material very flat and burr-free, which greatly improves the quality of the product.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3 This utility model provides a technical solution: a coreless fully automatic slitting machine, including an unwinding mechanism 1 and a main unit 4. A winding mechanism is installed on the rear side of the main unit 4 to realize the winding of materials. A slitting mechanism 5 is installed on the main unit 4 for the cutting of raw materials. The slitting mechanism 5 includes a fixing plate 51 fixed on the main unit 4. The slitting mechanism 5 also includes a crossbar 55 fixed on the main unit 4. A movable frame 57 that moves left and right is provided on the side of the crossbar 55. A cutting motor 58 is fixed on the movable frame 57. A cutting circular blade 59 is fixed at the output end of the cutting motor 58 to realize the cutting of raw materials.

[0017] A roll material 2 is installed on the unwinding mechanism 1, and a web guiding machine 3 is provided behind the unwinding mechanism 1. The web guiding machine 3 is located in front of the main unit 4. An air knife assembly 6 is also installed on the main unit 4, and the air knife assembly 6 is located between the slitting mechanism 5 and the web guiding machine 3. When using this coreless fully automatic slitting machine, such as Figures 1-3 As shown, by cooperating with the unwinding mechanism 1 and the winding mechanism installed at the rear of the main unit 4, the material on the roll 2 can move from front to back. When the material moves, it is located between the lower limit plate 53 and the upper limit plate 54. Through the action of the lower limit plate 53 and the upper limit plate 54, the material can be limited, thus preventing the material from shaking. The slitting mechanism 5 also includes a support plate 52 fixed to the host 4, and the support plate 52 is located below the front side of the cutting circular blade 59; a lower limit plate 53 fixed to the host 4 is provided on the rear side of the support plate 52, and an upper limit plate 54 fixed to the host 4 is provided above the lower limit plate 53, and the upper end surface of the lower limit plate 53 is flush with the upper end surface of the support plate 52, and the lower limit plate 53 is located below the rear side of the cutting circular blade 59; a servo motor 56 is also fixed on the crossbar 55, and a gear 561 is fixed at the output end of the servo motor 56, and another gear 561 is connected to the bearing. A toothed belt 562 is connected between the two gears 561 and the crossbar 55. A slider 571 is also fixed on the movable frame 57, and the slider 571 is slidably connected to the guide rail 572. The guide rail 572 is fixed on the crossbar 55, and the slider 571 and the toothed belt 562 are fixed to each other. A vertical rod 573 is also fixed on the movable frame 57, and a pressure plate 574 is fixed at the lower end of the vertical rod 573. The pressure plate 574 has a sloping structure on both the left and right sides. The pressure plate 574 is located above the support plate 52, and the lower end surface of the support plate 52 is flush with the lower end surface of the upper limit plate 54. Furthermore, during the material movement process, the air knife assembly 6 (an existing device, which will not be described in detail) can cut wide materials into narrow materials of a certain width. The cut narrow materials are then wound up by the winding mechanism. When the wound material needs to be cut, the cutting motor 58 is started to drive the cutting circular blade 59 to rotate, and the servo motor 56 is started simultaneously. The servo motor 56 drives the gear 561 and the toothed belt 562 to run. When the toothed belt 562 moves, it simultaneously drives the slider 571, the movable frame 57, and the cutting circular blade 59 to move, thereby realizing the material cutting function. When the movable frame 57 moves, the sliding guide between the slider 571 and the guide rail 572 ensures the stability of the movement of the movable frame 57 and the cutting circular knife 59. When the movable frame 57 drives the cutting circular knife 59 to move and cut the material, the lower limit plate 53 and the upper limit plate 54 can limit the material behind the cutting circular knife 59. With the help of the pressure plate 574 and the support plate 52, the material in front of the cutting circular knife 59 can be limited. This avoids the material from shaking due to the high speed of the cutting circular knife 59 when cutting the material edge, which would affect the flatness of the material cutting surface and effectively ensure the cutting quality of the material.
