[0014] The following further elaborates in detail the specific embodiments of the utility model with reference to the drawings.

[0015] By Figures 1 to 2Provided, the utility model includes a frame 1, a housing 2 is fixed on the frame 1, toothed rings 3 are sleeved on the front and rear ends of the housing 2, there are multiple rotatable gears 4 at both the front and rear ends of the housing 2, and the rotation of the multiple gears 4 can drive the toothed rings 3 thereon to rotate; there are multiple rubber rollers 5 evenly distributed in a circumferential manner between the two toothed rings 3, the ends of the rubber rollers 5 are fixedly connected to the toothed rings 3 without movement, there is an arc-shaped plate 6 with an upward opening on the lower side of the housing 2, the arc-shaped plate 6 is coaxial with the toothed rings 3, and the lower side of the arc-shaped plate 6 is fixedly connected to the frame 1; when the two toothed rings 3 drive the multiple rubber rollers 5 to rotate, the rubber rollers 5 can contact the arc-shaped plate 6, and the rubber rollers 5 can press the fabric to move along the upper surface of the arc-shaped plate 6; a cutting mechanism is fixed at the lower end of the housing 2, when the two lowest rubber rollers 5 press the fabric simultaneously and the fabric is in a horizontal state, the cutting mechanism can cut off the fabric.

[0016] For the convenience of cutting, the cutting mechanism includes a slider 7, the slider 7 is located on the lower side of the housing 2, the slider 7 can move back and forth, a telescopic unit is fixed at the lower end of the slider 7, a vertical cutting tool 8 is fixed at the lower end of the telescopic unit, a first motor 9 is connected to the cutting tool 8, and a second motor 11 is fixed at the lower end of the telescopic unit.

[0017] To achieve the back-and-forth movement of the slider 7, a lead screw 10 penetrating in the front-rear direction is provided on the slider 7, both ends of the lead screw 10 are rotatably fixed at the bottom of the housing 2, and the end of the lead screw 10 is connected to a second motor 11; guide rods 12 parallel to the lead screw are penetrated on both sides of the slider 7, and the ends of the guide rods 12 are fixed at the bottom of the housing 2; the rotation of the lead screw 10 can drive the slider 7 to move back and forth.

[0018] The telescopic unit is an electric cylinder or a pneumatic cylinder or a hydraulic cylinder.

[0019] To achieve the rotation of the toothed ring 3, the number of gears 4 on the front and rear sides of the housing 2 is equal and they are coaxially corresponding one by one, two corresponding gears 4 are fixed together through a rotating shaft 13, a pulley 14 is fixed in the middle of each rotating shaft 13, the multiple pulleys 14 are connected together through a belt, and the multiple rotating shafts 13 can rotate synchronously; a passive wheel 15 is fixed on one of the rotating shafts 13, a driving wheel 16 is meshed on one side of the passive wheel 15, and a third motor 17 is connected to the driving wheel 16, and the third motor 17 is fixed inside the housing 2.

The driven wheel 15 drives multiple rotating shafts 13 to rotate simultaneously via multiple belt pulleys 14. The simultaneous rotation of the multiple rotating shafts 13 causes the front and rear two toothed rings 3 to rotate simultaneously. The two toothed rings 3 drive multiple rubber rollers 5 to pass through the arc-shaped plate 6 in sequence. When the rubber roller 5 passes through the arc-shaped plate 6, the rubber roller 5 presses the fabric to move it to the right together. When the two rubber rollers 5 at the lowermost end straighten the fabric and keep it horizontal, the third motor 17 stops rotating. At this time, the telescopic unit moves downward and makes the cutter 8 contact the fabric. The rotation of the first motor 9 can drive the cutter 8 to cut the fabric. At this time, the second motor 11 rotates to drive the slider 7 to move back and forth, so that the fabric is completely cut by the cutter 8. After that, the third motor 17 continues to drive the toothed ring 3 to rotate, and the cut fabric slides out of the arc-shaped plate 6 to the right. The end of the fabric is driven to the right by the rubber roller 5 until the fabric is horizontal again. At this time, the next working cycle is carried out.

[0023] The utility model has a clever structure, can keep the fabric taut during the cutting process, does not require manual participation in pulling during the cutting process, completely avoids the safety threat of the cutter 8 to the operator, and greatly improves the fabric cutting efficiency.
