The driving roller and the driven roller are arranged on the frame. The driving roller and the driven roller are parallel to each other and have a certain gap therebetween. The driving roller is located below the driven roller. The frame includes two symmetrically arranged fixed frames. The fixed frames are provided with moving grooves and a plurality of positioning grooves. The two ends of the driven roller have roller shafts. Bearings are sleeved on the roller shafts at both ends. The outer rings of the bearings of the two roller shafts are respectively fixedly connected to the two fixed frames through a fixed disk. The middle of the fixed disk has a through hole. Positioning holes are provided on both sides of the through hole. The roller shaft on the same side is connected to the fixed frame. The inner ring of the bearing is fixedly connected to the roller shaft, and the outer ring of the bearing is fixedly connected to the through hole of the fixed disk. The fixed disk is fixed to the positioning groove of the fixed frame at the positioning hole. The roller shaft passes through the moving groove of the fixed frame.

[0014] As Figure 1 shown, a non-woven fabric shaping device of the present utility model includes a frame, a driving roller 1 and a driven roller 2. The driving roller 1 and the driven roller 2 are arranged on the frame. The driving roller 1 and the driven roller 2 are parallel to each other and have a certain gap therebetween. The driving roller 1 is located below the driven roller 2. The frame includes two symmetrically arranged fixing frames 3. The fixing frames 3 are provided with moving grooves 3-1 and a plurality of positioning grooves 3-2. The two ends of the driven roller 2 have roller shafts 2-1. Bearings are sleeved on the roller shafts 2-1 at both ends. The outer rings of the bearings of the two roller shafts 2-1 are respectively fixedly connected to the two fixing frames 3 through a fixing plate 4. As Figure 2As shown, the middle part of the fixed disk 4 has a through hole 4-1, and positioning holes 4-2 are arranged on both sides of the through hole 4-1. The roller shafts 2-1 on the same side are connected to the fixed frame 3. The inner ring of the bearing is fixedly connected to the roller shaft 2-1, and the outer ring of the bearing is fixedly connected to the through hole 4-1 of the fixed disk 4. The fixed disk 4 is fixed to the positioning groove 3-2 of the fixed frame 3 at the positioning hole 4-2. The roller shaft 2-1 passes through the moving groove 3-1 of the fixed frame 3. The driven roller 2 and the fixed disk 4 are respectively located on both sides of the fixed frame 3.

[0015] Each fixed frame 3 is also provided with a pressing assembly. The pressing assembly includes a fixed seat 5, a tension roller 6, a support rod 7 and a cylinder 8. One end of the support rod 7 is rotatably connected to the fixed frame 3. The tension roller 6 is fixed to the other end of the support rod 7. One end of the fixed seat 5 is fixed to the fixed frame 3, and the other end of the fixed seat 5 extends away from the driven roller 2. The cylinder body of the cylinder 8 is rotatably connected to the fixed seat 5, and the end of the extending end of the cylinder 8 is rotatably connected to the middle part of the support rod 7.

[0016] The positioning hole 4-2 of the fixed disk 4 is fixed to the positioning groove 3-2 of the fixed frame 3 through a bolt 9.

[0017] One row of positioning grooves 3-2 is arranged on each side of the moving groove 3-1, and the positioning grooves 3-2 on both sides of the moving groove 3-1 are symmetrically distributed relative to the moving groove 3-1.

[0018] The center distance between the two rows of positioning grooves 3-2 is equal to the center distance between the positioning holes 4-2 on both sides of the through hole 4-1.

[0019] The driving roller 1 is driven to rotate by a driving mechanism. The non-woven fabric is pressed between the driving roller 1 and the driven roller 2.

The fixed disk 4 and the roller shaft 2-1 of the driven roller 2 are fixed through a bearing. When the position of the fixed disk 4 on the fixed frame 3 changes, the height position of the driven roller 2 changes. The specific adjustment method is that the positioning holes 4-2 on both sides of the fixed disk 4 are respectively fixed to two positioning grooves 3-2 at the same height on the fixed frame 3 through a bolt 9, and the roller shaft and the bearing of the driven roller 2 can move in the moving groove 3-1.
