At this time, the slitting assembly is adjusted to contact the non-woven fabric, thereby achieving slitting of the non-woven fabric.

[0010] Compared with the traditional two-axis linear motion of driving the slitting component for translation + feeding, this solution uses the translation of the screw pair + angle adjustment of the slitting component to achieve slitting of non-woven fabrics.

[0015] It should be noted that during the slitting process, the rotation of the winding roller is always maintained.

[0016] In order to limit the linear motion of the tool holder during the movement, the utility model adopts the fixed frame, which is provided with a limiting groove along the length direction;The two sides of the tool holder are provided with limiting protrusions matched with the limiting grooves;

[0017] When the second cylinder works, the limiting protrusions move relative to the limiting grooves, and in turn drive the linear motion of the tool holder relative to the fixed frame.

[0018] In order to illustrate the linear connection relationship between the rotating shaft and the sliding sleeve, the utility model adopts the rotating shaft, which is provided with a spline groove along the axial direction;The inner hole of the sliding sleeve is provided with a spline matched with the spline;

DETAILED DESCRIPTION

[0028] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0029] like Figure 1-3 As shown, the utility model is a non-woven fabric slitting machine, comprising: a frame 1; a rotating shaft 2, which is rotatably arranged on the frame 1; a sliding sleeve 3, which is slidably arranged on the rotating shaft 2; a screw rod 4, which is rotatably arranged on the frame 1 and is arranged parallel to the rotating shaft 2, one end of which is driven to rotate by a motor 5; a nut 6, which is threadedly connected to the screw rod 4, and a limit plate 7 is provided on the nut and is plugged and connected to the sliding sleeve 3; a slitting assembly 8, which is fixedly connected to the sliding sleeve 3; a driving assembly 9, which is connected to the frame 1 and the rotating shaft 2, and is suitable for driving the rotating shaft 2 together with the sliding sleeve 3 to rotate, driving the slitting assembly 8 to swing, and cut the non-woven fabric on the winding roller 10;

[0030] In this solution, the motor drives the screw to rotate, and the screw drives the nut to move linearly. The nut and the sleeve are connected by a limit plate, which in turn drives the sleeve on the rotating shaft to move linearly.

[0031] When the sliding sleeve drives the slitting assembly to move to the slitting position, the driving assembly works, and the rotating shaft is driven to rotate, driving the sliding sleeve to rotate. At this time, the slitting assembly is adjusted to contact the non-woven fabric, thereby achieving slitting of the non-woven fabric.

[0032] Compared with the traditional two-axis linear motion of driving the slitting component for translation + feeding, this solution uses the translation of the screw pair + angle adjustment of the slitting component to achieve slitting of non-woven fabrics.

[0033] like Figure 2 As shown, in order to illustrate the specific structure of the driving assembly, the driving assembly 9 used in the present invention includes: a first cylinder 91, whose cylinder body is hinged to the frame 1; a connecting rod 92, one end of which is fixedly connected to the rotating shaft 2, and the other end of which is hinged to the output end of the first cylinder 91;

[0034] One end of the first cylinder is hinged to the frame, and the other end is hinged to the connecting rod, and the other end of the connecting rod is fixedly connected to the rotating shaft; when the piston rod of the first cylinder is extended, the connecting rod rotates downward, thereby driving the slitting assembly to rotate downward; the same applies vice versa.

[0035] like Figure 3 As shown, in order to illustrate the specific structure of the slitting assembly, the slitting assembly 8 adopted by the present invention includes: two fixed frames 81 arranged opposite to each other, whose ends are fixedly connected to the sliding sleeve 3; a second cylinder 82, whose cylinder body is fixed between the two fixed frames 81; a knife holder 83, which is connected to the output end of the second cylinder 82; a slitting knife 84, which is arranged on the knife holder 83; when the second cylinder 82 is working, the knife holder 83 extends along the length direction of the fixed frame 81, and the end of the slitting knife 84 extends out of the fixed frame 81 and abuts against the non-woven fabric;

[0036] When the slitting knife approaches the non-woven fabric, the second cylinder works, connecting the knife holder to the slitting knife for linear motion, extending the cutting surface of the slitting knife out of the fixed frame and contacting the non-woven fabric roll, and the non-woven fabric is cut through the feeding movement of the slitting knife;

[0037] It should be noted that during the slitting process, the winding roller must always be kept rotating.

[0038] like Figure 3 As shown, in order to limit the tool holder to always move in a straight line during the movement, the present invention adopts the fixed frame 81 to open a limiting groove 85 along its length direction; the two sides of the tool holder 83 are provided with limiting protrusions corresponding to the limiting groove 85;

[0039] When the second cylinder is working, the limiting protrusion moves relative to the limiting groove, thereby driving the tool holder to move linearly relative to the fixed frame.

[0040] In order to illustrate the linear connection relationship between the rotating shaft and the sliding sleeve, the present invention adopts the rotating shaft 2 to be provided with a spline groove along its axial direction; the inner hole of the sliding sleeve 3 is provided with a spline that cooperates with the spline;

[0041] The spline groove is opened along the axis of the rotating shaft and on the outer surface of the rotating shaft. The spline of the sliding sleeve cooperates with the spline groove, so that the sliding sleeve can move along the axial direction relative to the rotating shaft, and can also realize the sliding sleeve rotating with the rotating shaft.

[0042] like Figure 3 As shown, in order to illustrate the specific structure of the limiting piece, the present invention adopts the sliding sleeve 3 as a rotating body, and a slot 31 is provided on its outer peripheral wall; one end of the limiting piece 7 is fixedly connected to the nut 6, and the other end is provided with an arc-shaped notch that matches the slot 31;

[0043] The arc-shaped notch of the limit plate is matched with the slot, so that the torque of the sliding sleeve's rotation will not be transmitted to the straight nut through the limit plate; the nut only moves linearly relative to the screw rod.

[0044] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
