[0028] See also Figure 1-6 As shown, the utility model relates to an embossing device for non-woven fabric production, including: a workbench 1, a gantry 2, a slide rail 3, a slider 31, a driving cylinder 4, a connecting rod 5, an extrusion roller 6, a connecting plate 7, a roller group 8, a roller 81, a connecting frame 82, a servo motor 83, a transmission gear 84, a pressure roller 85, an embossing assembly 9, an upper embossing member 91, a lower embossing member 92, a fixed frame 93, a first motor 911, a rotating shaft 912, a rotating base 913, a first mounting member 914, a second mounting member 915, a pressure roller 916, a tightening mechanism 10, an adjusting roller 101, a support column 102 and a rotating shaft 103. A gantry 2 is provided on the workbench 1, and slide rails 3 are provided on both sides of the inner wall of the gantry 2. The slide rails 3 are used to guide and support the movement of the slider 31 to ensure the movement. In order to ensure smooth and stable movement, two driving cylinders 4 are symmetrically arranged on the top of the gantry 2, and the two driving cylinders 4 are connected with connecting rods 5. The driving cylinders 4 are used to provide power to drive the operation. The two driving cylinders 4 respectively control the movement of the two connecting rods 5. The connecting rods 5 are connected by a servo motor 83 to transmit power and control the movement of the squeezing roller 916. The two connecting rods 5 are fixedly connected with the squeezing roller 916, and the position and pressure of the squeezing roller 916 are controlled by the movement of the connecting rods 5. Connecting plates 7 are arranged on both sides of the squeezing roller 916, and sliding blocks 31 corresponding to the slide rails 3 are arranged on the connecting plates 7 to ensure stable and precise movement of the squeezing roller 916. A roller group 8 is arranged on the workbench 1, and the roller group 8 is arranged directly below the squeezing roller 916. An embossing component 9 is arranged on one side of the roller group 8.

[0029] The support column 102 is arranged on both sides of the workbench 1. The two adjusting rollers 101 are connected together by the cross-connecting plates at the ends. The weight of one adjusting roller 101 is 1.1 to 1.2 times the weight of the other adjusting roller 101. Due to the different weights of the two adjusting rollers 101, when the adjusting rollers are not in use, the adjusting rollers are in a natural vertical state. When the non-woven fabric is flattened, the non-woven fabric rotates with the adjusting rollers to apply appropriate pressure to the non-woven fabric to ensure that it maintains appropriate tension during the winding process. The two rotating shafts 103 are coaxially connected and rotated. On the support column 102, the inner end of the rotating shaft 103 is fixedly connected to the middle position of the cross-connecting plate to fix the position of the support column 102 and ensure the stability of the material tension during processing; the roller group 8 includes multiple rollers 81, a connecting frame 82, a servo motor 83, a transmission gear 84 and a pressure roller 85. The multiple rollers 81 are all arranged in the connecting frame 82, and the rollers 81 are rotatably connected with the connecting frame 82. The servo motor 83 and the transmission gear 84 are both arranged on one side of the connecting frame 82, and the output shaft of the servo motor 83 is connected with the transmission gear 84. The servo motor 83 is started to provide power to drive the transmission gear 84, and the transmission gear 84 drives the two rollers 81 to rotate relative to each other, so that the non-woven fabric is transmitted. The multiple rollers 81 contain a pressure roller 85 corresponding to the squeezing roller 916, and the pressure roller 85 is a convex roller with a large diameter in the middle and a small diameter at both ends. The corresponding squeezing roller 6 is a concave roller adapted to the pressure roller 85. When the non-woven fabric passes through the squeezing roller 6 , the concave portion of the squeezing roller 6 can compact the non-woven fabric and flatten the surface, thereby ensuring the flatness and density of the non-woven fabric.

[0030] The embossing assembly 9 includes an upper embossing member 91, a lower embossing member 92 and a fixing frame 93. The fixing frame 93 is arranged on the workbench 1. A partition is arranged in the middle of the fixing frame 93. The upper embossing member 91 is arranged on the top of the partition, and the lower embossing member 92 is arranged at the bottom of the partition. The upper embossing member 91 is used in conjunction with the lower embossing member 92 to apply pressure to form a patterned member. The upper embossing member 91 includes a first motor 911, a rotating shaft 912, a rotating base 913, a first mounting member 914, a second mounting member 915 and a pressing roller 916. The output shaft of the first motor 911 is connected to the rotating shaft 912. The rotating shaft 912 is connected to the rotating shaft 912. A first mounting member 914 is provided on the side, and a second mounting member 915 is provided on the side of the rotating base 913. The first mounting member 914 and the second mounting member 915 are connected through a pressure roller 916. A positioning block is provided on the first mounting member 914, and a corresponding mounting block is provided on the pressure roller 916. The positioning block and the mounting block are connected through a locking block. The lower embossing member 92 has the same structure as the upper embossing member 91, and a gap is provided between the upper embossing member 91 and the lower embossing member 92 to realize embossing movement. The lower embossing member 92 is at the same horizontal height as the roller 81, and the lower embossing member 92 is arranged opposite to the upper embossing member 91. By starting the motors on the upper embossing member 91 and the lower embossing member 92, the first motor 911 will provide power to drive the movement of the rotating shaft and the pressing roller 916. The speed and direction of the motor can be adjusted as needed to control the strength and speed of embossing to ensure that the position and pressure of the embossing member are appropriate so as to produce the desired pattern effect during the processing. During use, when the non-woven fabric enters between the upper and lower embossing members 92, the motor is started so that the embossing member begins to apply pressure to perform the embossing process.

[0031] Specifically, if the printed pattern of the non-woven fabric needs to be changed, the pressing roller 916 can be manually disassembled and replaced through the first mounting member 914 and the second mounting member 915 .

[0032] When the utility model is used for embossing equipment for non-woven fabric production, the non-woven fabric roll to be embossed is placed on an external placement rack, one end of the non-woven fabric is placed in the embossing assembly 9 through the roller group 8 and the tensioning mechanism 10 on the workbench 1, the driving cylinder 4 in the equipment is started, and the movement of each connecting rod 5 is controlled by controlling the driving cylinder 4, and the power is transmitted to the squeezing roller 6 through the connecting rod 5. The squeezing roller 6 performs a flattening treatment on the non-woven fabric material. When the flattening treatment is performed, the tension of the material in the flattening process is adjusted and controlled through the tensioning mechanism 10 to prevent the non-woven fabric from being relaxed during the flattening process. After the flattening treatment is completed, the non-woven fabric is transferred to the embossing assembly 9 through the bottom roller group 8 and the tensioning mechanism 10. When the embossing treatment is completed, the operation of the driving cylinder 4 is stopped, the equipment is closed, and the non-woven fabric material that has been embossed is removed.
