Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the non-woven fabric stretching device comprises a frame 1, a fixed roller 2 and a stretching roller 3;

the axes of the pair of fixed rollers are parallel to each other, two ends of the fixed wheel are arranged on the frame through bearings,

the axis of the stretching roller is parallel to the axis of the fixed roller, two ends of the stretching roller are mounted on an adjusting frame 4 through bearings, the adjusting frame is provided with a pair of parallel threaded holes, the threaded holes are connected with a screw rod 5, the extending direction of the screw rod is perpendicular to the axis direction of the stretching roller, the screw rod is mounted on the rack through the bearings, the pair of screw rods are connected with a same transmission shaft 7 through a bevel gear 6, the transmission shaft is connected with a motor 9 through a pair of transmission gears 8, the transmission shaft is mounted on the rack 10 through the bearings, and the motor is fixedly mounted on the rack. Still be equipped with mounting bracket 11, the mounting bracket is equipped with slide 12 and lower slide 13, and the mounting bracket rotates and connects horizontal screw 14, and the frame is equipped with screw hole, goes up spout and lower spout, and horizontal screw is connected with the screw hole, and horizontal screw is perpendicular with the direction of motion of lead screw, sliding connection between last slide and the last spout, sliding connection between lower spout and the lower spout.
