[0003] The current slitting structure is simple, and generally a high-speed circular knife is used to cut the entire wide roll into multiple narrow-specification rolls. However, the current high-speed circular knife is directly fixed on the driving roller, which makes it difficult to adjust the position of the high-speed circular knife and to quickly adjust different cutting widths. In addition, the high-speed circular knife is not easy to disassemble and repair after installation, and the driving roller needs to be disassembled, which greatly reduces its efficiency. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a non-woven composite slitting machine, in which the cutting circular knife is composed of two half-cutting blades, which can be directly removed from the driving roller by disassembly, and the position of the cutting circular knife can be quickly adjusted to solve the problems raised in the above-mentioned background technology.

The inner side of the half-cutting blade is contacted with the outer side of the driving roller, and the open end faces of the half-cutting blade are abutted. The half-cutting blades on one side are installed with multiple fixing plates, and the other ends of the fixing plates extend to the half-cutting blades on the other side. A first screw hole is provided on the other end of the fixing plate, and a second screw hole is provided on the half-cutting blade on the other side opposite to the first screw hole, and hand-tightening bolts are threadedly connected in the opposite first screw holes and second screw holes.

[0007] As a preferred technical solution, a plurality of positioning grooves are axially arranged on the outer wall surface of the driving roller, and the inner side surfaces of the half-cutting blades protrude opposite to the positioning grooves to form positioning parts, which are slidably arranged in the positioning grooves.

[0008] As an optimal technical solution, multiple ball grooves are provided on both side surfaces inside the U-shaped plate, and balls are movably installed in the ball grooves. Part of the balls extend to the outside along the openings of the ball grooves and are arranged in contact with the two side surfaces of the cutting circular knife.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a non-woven fabric composite slitting machine of the utility model comprises a driving roller 1, a transverse plate 7 and a plurality of circular cutting knives, wherein the transverse plate 7 is arranged parallel to the driving roller 1, and the circular cutting knives are all sleeved on the outside of the driving roller 1, and a slide groove 14 is provided on the bottom surface of the transverse plate 7, and a slider 13 is slidably installed at the slide groove 14 opposite to the circular cutting knife, and a pressing plate 12 for synchronously pressing and positioning the slider 13 is also provided inside the slide groove 14, and one end of the slider 13 extends to the outside along the opening of the slide groove 14, and is installed with a U-shaped plate 8, which is sleeved on the outside of the circular cutting knife.

[0023] In this embodiment, the cutting circular knife is divided into two halves and consists of two half-cutting blades 2. The inner side of the half-cutting blade 2 is arranged in contact with the outer side of the driving roller 1, and the open end faces of the half-cutting blade 2 are arranged in abutment with each other. The half-cutting blade 2 on one side is installed with multiple fixing plates 3, and the other end of the fixing plate 3 extends to the half-cutting blade 2 on the other side. A first screw hole is provided on the other end of the fixing plate 3, and a second screw hole is provided at the half-cutting blade 2 on the other side opposite to the first screw hole, and hand-tightening bolts 11 are threadedly connected in the first screw hole and the second screw hole relative to each other.

[0024] In this embodiment, a plurality of positioning grooves 4 are axially arranged on the outer wall surface of the driving roller 1 , and the inner side surfaces of the half-cutting blades 2 protrude opposite to the positioning grooves 4 to form positioning portions 5 , which are slidably arranged in the positioning grooves 4 .

[0025] In this embodiment, multiple ball grooves are provided on both side surfaces inside the U-shaped plate 8, and balls are movably installed in the ball grooves. Part of the balls extend to the outside along the openings of the ball grooves and are arranged in contact with the two side surfaces of the cutting circular knife. The cutting circular knife can be limited by the balls so that the cutting circular knife can only rotate along the balls, thereby reducing friction.

[0026] In this embodiment, the cross-sections of the slide groove 14 and the slider 13 are both arranged in an "L"-shaped structure, and the slider can be hooked by the L-shaped structure to prevent the slider from falling out of the slide groove directly.

[0027] In this embodiment, support plates 6 are installed at both ends of the cross plate 7, and bearings 10 are embedded in the support plates 6 opposite to the driving roller 1. The roller shafts at both ends of the driving roller 1 are installed in the inner ring of the bearing 10, and a motor for driving the driving roller 1 to rotate is installed on one side of the support plate 6.

[0028] In this embodiment, a plurality of through holes are provided on one side of the horizontal plate 7, and a cylinder 9 is installed at one side of the horizontal plate 7 facing the through holes, and the piston rods of the cylinders 9 are installed on the pressure plate 12 through the through holes;

[0029] Wherein, the side surface of the pressure plate facing the slider is provided with anti-skid grooves, thereby increasing the friction with the slider;

[0030] Among them, a scale is arranged on one side surface of the horizontal plate, through which the distance moved by the slider can be known.

[0031] When in use, first adjust the distance between the cutting circular knives according to the required cutting width. When adjusting, start the cylinder to retract the piston rod of the cylinder. The movement of the piston rod drives the pressure plate so that the pressure plate can be moved away from the slider. After the slider loses the extrusion force from the pressure plate, the slider can move back and forth along the slide groove. The movement of the slider drives the U-shaped plate. The movement of the U-shaped plate can push the cutting circular knife so that the cutting circular knife can move along the positioning groove to complete the adjustment of the width. After the distance is determined, the cylinder can be started again to extend the piston rod of the cylinder, and the slider is pressed and positioned through the pressure plate, and the positioning of the U-shaped plate and the cutting circular knife is also completed synchronously.

[0032] After the above is completed, the motor can be started, and the start of the motor drives the driving roller. The rotation of the driving roller can drive the rotation of the cutting circular knife through the positioning groove and the positioning part, so that the cutting circular knife rotates continuously along the ball bearing;

[0033] Among them, when the cutting circular knife needs to be disassembled, the hand screw bolt can be directly screwed out. After the fixation of the hand screw bolt is lost, the plate cutting blade can be directly removed from the driving roller outward without disassembling the driving roller, which greatly increases the convenience.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
