During the process of the non-woven fabric being flattened by the flattening mechanism after being preheated, the extrusion ring rotates to push the non-woven fabric toward the edge to unfold it. The center of the non-woven fabric after being compressed by the first roller is compressed. At the same time, the extrusion ring rotates to unfold the edge of the non-woven fabric to reduce longitudinal wrinkles. Then, the second roller squeezes the edge of the non-woven fabric to flatten the edge of the non-woven fabric.

The rubber belt above the clamp rotates clockwise. The rubber belt under the clamping plate rotates counterclockwise; the surface of the rubber belt is inclined, and the edge of the non-woven fabric enters between the two rubber belts. As the rubber belt rotates, the rubber belt drives the rubber strip with a semicircular cross-section to contact the edge of the non-woven fabric. The semicircular cross-section of the rubber strip facilitates the rubber strip to slide through the side wall of the non-woven fabric to avoid excessive movement resistance of the rubber strip, and the contact area between the rubber strip and the non-woven fabric is large, which facilitates the rubber strip to flatten the edge of the non-woven fabric outward; the flattening machine The structure makes the non-woven fabric have uniform overall thickness and smooth surface, and the flattening mechanism makes the non-woven fabric flat, and then the rubber strip and the rubber belt push the edge of the non-woven fabric to expand outward, so as to flatten the non-woven fabric as a whole again, reduce the wrinkles on the surface of the non-woven fabric, and then perform the laminating operation to improve the laminating quality, and the rubber strip and the rubber belt are elastic. When the rubber strip squeezes the non-woven fabric, the rubber strip and the rubber belt are deformed to avoid excessive squeezing force between the rubber strip and the non-woven fabric, thereby avoiding the non-woven fabric from being stretched.

The heated air enters the grooves 36 through the connecting pipe 37. The air moves downward along the grooves 36. The grooves 36 are funnel-shaped. The air moving downward in the grooves 36 will gradually converge and accelerate. The distance between the bottom plate 35 and the non-woven fabric 5 and the depth of the grooves 36 gradually decrease from top to bottom, so that the space between the heated air and the non-woven fabric 5 is reduced. The spacing is getting smaller and smaller, and as the air moves downward, the air flow rate is getting faster and faster, so that the air can quickly blow away the impurities on the surface of the non-woven fabric 5, keep the surface of the non-woven fabric 5 clean, and as the non-woven fabric 5 moves upward along the bottom plate 35, the hot air continuously heats the surface of the non-woven fabric 5; the groove 36 is inclined on the bottom surface of the bottom plate 35, and the inclination angle of the groove 36 gradually increases from the center of the bottom plate 35 toward the edge of the bottom plate 35, so that the wind blown out from the inside of the groove 36 continuously blows to the edge of the non-woven fabric 5, flattens the surface of the non-woven fabric 5, and reduces the wrinkles on the surface of the non-woven fabric 5.

When the first roller 73 contacts the non-woven fabric 5, the extrusion ring 76 also moves with the edge of the non-woven fabric 5; and the installation directions of the extrusion rings 76 at both ends of the first roller 73 are opposite, so that the spiral extrusion rings 76 push the edge of the non-woven fabric 5 to expand outward, so that the surface of the non-woven fabric 5 is flattened, which is convenient for the first roller 73 to squeeze the surface of the non-woven fabric 5; and the extrusion ring 76 pushes the non-woven fabric 5 to move outward to reduce the longitudinal wrinkles at the edge of the non-woven fabric 5, and then After that, the non-woven fabric 5 contacts the second roller 74, the diameter of the second roller 74 is large at both ends and small in the middle, and the two ends of the second roller 74 contact the edges of the unfolded non-woven fabric 5 to flatten the edges of the non-woven fabric 5, and finally the third roller 75 flattens the entire surface of the non-woven fabric 5 again, so that the overall thickness of the non-woven fabric 5 is uniform and the surface is smooth; according to the roughness of the surface of the non-woven fabric 5, by operating the hydraulic rod 42, the hydraulic rod 42 drives the fixing frame 45, the bearing sleeve 43, the first roller 73, the second roller 74 and the third roller 75 to move up and down, and changes the spacing between the first roller 73, the second roller 74 and the third roller 75 and the supporting roller 71, so as to adjust the pressure on the non-woven fabric 5; if the surface roughness of the non-woven fabric 5 is large, the pressure of the roller on the non-woven fabric 5 is increased, and if the surface roughness of the non-woven fabric 5 is small, the pressure of the roller on the non-woven fabric 5 is reduced, so that the surface of the non-woven fabric 5 is flattened.The flattened non-woven fabric 5 enters the interior of the clamping plate 61, and at this time the first motor 67 drives the first gear 65 and the fixed shaft 62 to rotate, and the fixed shaft 62 drives the rubber belt 63 to rotate, the rubber belt 63 above the clamping plate 61 rotates clockwise, and the rubber belt 63 below the clamping plate 61 rotates counterclockwise; the surface of the rubber belt 63 is inclined, and the edge of the non-woven fabric 5 enters between the two rubber belts 63. As the rubber belt 63 rotates, the rubber belt 63 drives the rubber strip 64 with a semicircular cross-section to contact the edge of the non-woven fabric 5. The cross-section of the rubber strip 64 is semicircular, which facilitates the rubber strip 64 to slide through the side wall of the non-woven fabric 5. , to avoid excessive resistance to the movement of the rubber strip 64, and the rubber strip 64 is in strip shape and has a large contact area with the non-woven fabric 5, so that the rubber strip 64 can flatten the edge of the non-woven fabric 5 outward; the flattening mechanism 7 makes the overall thickness of the non-woven fabric 5 uniform and the surface smooth, and at the same time, the flattening mechanism 7 makes the non-woven fabric 5 in a flattened state, and then the rubber strip 64 and the rubber belt 63 push the edge of the non-woven fabric 5 to expand outward, thereby flattening the non-woven fabric 5 as a whole again, and the flattened non-woven fabric 5 moves to the bottom of the laminating nozzle 5, at this time, the melted plastic enters the interior of the laminating box 12, and the melted plastic is then applied to the surface of the non-woven fabric 5 through the laminating nozzle 13 for laminating processing.
