[0002] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is called cloth because it has the appearance and certain properties of cloth. The patent with application number 202123195732.5 discloses an embossing device for non-woven wallpaper, including a rectangular frame and an auxiliary mechanism. An embossing mechanism is arranged inside the rectangular frame. The embossing mechanism includes an active roller and an embossing roller. The active roller is rotatably connected to the inner wall of the rectangular frame. The embossing roller is movably arranged above the active roller. A lifting mechanism is arranged above the embossing roller, so that the gap between the embossing roller and the active roller can be adjusted according to actual conditions. However, during embossing, the embossing roller is driven to rotate by the active roller through the non-woven fabric located between the two. Therefore, the lower surface of the non-woven fabric located between the two will be subjected to a force in the same direction as its forward direction, and the upper surface will be subjected to a force in the opposite direction to its forward direction, and the non-woven fabric is easily damaged.

[0011] Specific implementation method: Combination Figure 1As shown, a non-woven fabric embossing device comprises a frame 1, in which a roller 2 is rotatably connected, and the position of the roller 2 is not adjustable, a U-shaped frame 4 is slidably connected in the frame 1, and a lifting drive device 5 capable of driving the U-shaped frame 4 to rise and fall is arranged on the top of the frame 1, and an embossing roller 3 is rotatably connected to the lower part of the U-shaped frame 4, and a pattern is arranged on the outer circumferential surface of the embossing roller 3, and the embossing roller 3 is located above the roller 2, and a first worm gear 21 is arranged at one end of the roller 2, and a second worm gear 31 is arranged at one end of the embossing roller 3, and a bidirectional worm 7 is also rotatably connected to the frame 1, and the bidirectional worm 7 is provided with a positive thread portion and a negative thread portion respectively meshing with the first worm gear 21 and the second worm gear 31, and the bidirectional worm 7 is transmission-connected to the motor 6. The motor 6 drives the bidirectional worm 7 to rotate, which can drive the roller 2 and the embossing roller 3 to rotate simultaneously and in opposite clockwise directions. Of course, in order to minimize the damage to the non-woven fabric, the linear speeds of the outer circumferential surfaces of the roller 2 and the embossing roller 3 are equal. It is preferred that the radius of the roller 2 and the embossing roller 3 are equal, and the number of teeth of the first worm gear 21 and the second worm gear 31 are equal. When the embossing roller 3 is raised and lowered to adjust the gap between it and the roller 2, the second worm gear 31 will rotate a corresponding angle to maintain meshing with the bidirectional worm 7.
[0012] Specifically, the lifting drive device 5 is a hydraulic cylinder or a servo electric cylinder, and the piston rod of the hydraulic cylinder or the servo electric cylinder penetrates the top of the frame 1 and is connected to the U-shaped frame 4.
[0013] Furthermore, the first worm gear 21 is located on the outside of the frame 1, the journal at one end of the roller 2 (as a commonly used technical means, both ends of the roller 2 are provided with journals) extends to the outside of the frame 1 and is connected to the first worm gear 21, the second worm gear 31 is located on the outside of the frame 1, a through portion 11 is provided on one side of the frame 1, the journal at one end of the embossing roller 3 (as a commonly used technical means, both ends of the embossing roller 3 are provided with journals) penetrates one side of the U-shaped frame 4 and passes through the through portion 11 to be connected to the second worm gear 31, and the bidirectional worm 7 is also located on the outside of the frame 1.
[0014] When in use, the support roller 2 and the embossing roller 3 can rotate simultaneously in opposite clockwise directions and with equal linear speeds on the outer circumferences, so that the forces on the upper and lower surfaces of the nonwoven fabric between the two are in the same direction, thereby causing less damage to the nonwoven fabric.
