[0002] Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, colorful, low-priced, and recyclable. For example, polypropylene pellets are often used as raw materials, and are produced by a continuous one-step process of high-temperature melting, spinning, laying, and hot pressing and winding. When the non-woven fabric is cut, the excess part of the non-woven fabric needs to be cut, usually by a pair of trimming blades driven by a motor. However, the defects of the prior art are as follows:

[0040] Embodiment 1:

[0041] As Figures 1 to 3 shown, the embodiment of the present application provides a non-woven fabric cutting machine, including a body 1, a cross-cutting knife 2, a pair of trimming cutter heads 3, a feeding roller group 4 and a discharging roller group 5, and further including an adjusting mechanism 6 for controlling the relative movement of the pair of trimming cutter heads 3.

[0042] Further, the adjusting mechanism 6 includes a pair of adjusting frames 61, symmetrically and slidably installed on one side of the inner cavity of the machine body 1; a pair of screw sleeves 62, respectively fixed on the opposite side walls of the pair of adjusting frames 61; a double-shaft motor 63, which is fixed between the pair of adjusting frames 61, and a pair of output shafts are respectively drivingly connected to the respective screw sleeves 62 through a pair of screw rods 64, and each trimming cutter head 3 is respectively rotatably installed in each adjusting frame 61.

[0043] Further, it further includes a pair of rotating shaft sleeves 7, respectively rotatably installed on each adjusting frame 61 through ball bearings; a driving device 8, which is used to drive the pair of rotating shaft sleeves 7 to rotate, and each trimming cutter head 3 is respectively fixedly installed on each rotating shaft sleeve 7.

[0044] Further, the adjusting mechanism 6 further includes a pair of pressure rollers 65, respectively rotatably installed on each adjusting frame 61 through bearings, and drivingly connected to the adjacent rotating shaft sleeves 7 through a gear set; a pair of knife grooves 66, respectively arranged on the circumferential walls of the respective pressure rollers 65, and the outer circumferential wall of each trimming cutter head 3 can cooperate with the corresponding knife groove 66.

[0045] Further, the driving device 8 includes an installation box 81, which is fixed on the top of the machine body 1; a rotating shaft 82, which is rotatably installed in the installation box 81 through a ball bearing, and both ends extend outside the installation box 81; a pair of transmission rods 83, one ends of which are respectively fixed on the two ends of the rotating shaft 82, and the other ends are respectively slidably inserted into the respective rotating shaft sleeves 7; a reduction motor 84, and its output shaft is in belt transmission with the rotating shaft 82.

[0046] Preferably, the cross-sectional shape of each transmission rod 83 and the cross-sectional shape of the inner cavity of the corresponding rotating shaft sleeve 7 are both rectangular.

[0047] Preferably, the machine body 1 is a box body, an outlet 9 is provided on the front end side wall, an inlet 10 is provided on the rear end side wall, a baffle 11 is provided near the outlet 9 side in the middle of the inner cavity, and a pair of adjusting frames 61 can slide between the end surface of the baffle 11 away from the outlet 9 and the side wall of the inner cavity of the machine body 1 where the inlet 10 is provided.

[0048] Preferably, both the feeding roller group 4 and the discharging roller group 5 include a pair of rotating rollers that are drivingly connected to each other through gears and driven by a motor. The feeding roller group 4 is arranged on the outer side wall of the machine body 1 with the outlet 9. There is a notch on the baffle 11, and the feeding roller group 4 is arranged in this notch for sending the non-woven fabric passing through the pair of trimming cutter heads 3 under the cross-cutting knife 2.

[0049] In this embodiment of the present application, due to the adoption of the above structure, the non-woven fabric to be cut enters the machine body 1 from the inlet 10, passes through a pair of trimming cutter discs 3 for trimming, and then is pushed by the feeding roller group 4 to pass through the outlet 9 and extend into the discharging roller group 5. The air cylinder drives the cross-cutting knife 2 to descend to cut the trimmed non-woven fabric. The discharging roller group 5 moves the cut non-woven fabric outside the outlet 9, and the feeding roller group 4 pushes the non-woven fabric that has completed trimming into the outlet 9. When it is necessary to adjust the distance between a pair of trimming cutter discs 3, the double-shaft motor 63 operates to rotate a pair of screw rods 64, and cooperates with the corresponding screw sleeves 62 to control a pair of adjusting frames 61 to approach / separate from each other, so as to adjust the distance between a pair of trimming cutter discs 3 rotatably mounted on each adjusting frame 61 through bearings. During this process, the position of the rotating shaft 82 remains unchanged, and the lengths of the transmission rods 83 extending into the inner cavities of the corresponding rotating shaft sleeves 7 change. Still, when the reduction motor 84 operates, it can drive a pair of rotating shaft sleeves 7 to rotate. When the pair of rotating shaft sleeves 7 rotate, they drive the corresponding pressing rollers 65 to rotate through the gear set, so that a pair of trimming cutter discs 3 cooperate with the corresponding knife grooves 66 to cut the sides of the non-woven fabric.
