[0025] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all embodiments. Based on the embodiment of the utility model, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0026] Ginseng Figure 1 and Figure 2The utility model provides an artificial leather production system 1000, which is used to produce artificial leather 100, such as PVC artificial leather, TPO artificial leather, PU artificial leather, TPU artificial leather, etc. The artificial leather 100 includes an artificial leather surface 101 and a base fabric 102. The artificial leather production system 1000 includes an artificial leather surface production system (not shown), a base fabric unwinding mechanism 200, a multi-layer material bonding system 300 and a transfer rack 400.

[0027] Continue to participate Figure 1 and Figure 2 The multi-layer material laminating system 300 comprises a support 1, a laminating mechanism 2 and a rotatable unrolling roller 3. The support 1 is used to install and support the laminating mechanism 2 and the unrolling roller 3. The laminating mechanism 2 is used to laminate the artificial leather surface 101 and the base fabric 102. In this embodiment, the laminating mechanism 2 comprises two laminating rollers 21 and 22 arranged opposite to each other, and the laminating mechanism 2 forms a laminating area 20 between the two laminating rollers 21 and 22. The unrolling roller 3 is used to flatten the base fabric 102 and guide it to the laminating area 20.

[0028] Ginseng Figure 1 and Figure 5 , the surface of the unfolding roller 3 has a plurality of inclined first annular grooves 31 and a plurality of inclined second annular grooves 32. Along the axial direction O of the unfolding roller 3, the inclination directions of the first annular grooves 31 are the same and are located on one side of the unfolding roller 3, the inclination directions of the second annular grooves 32 are the same and are located on the other side of the unfolding roller 3, and the inclination directions of the first annular grooves 31 and the second annular grooves 32 are axially symmetrical. The utility model arranges the unfolding roller 3 and arranges the inclination directions of the plurality of first annular grooves 31 and the plurality of second annular grooves 32 to be axially symmetrical, thereby evenly flattening the base fabric 102, improving the bonding effect between the artificial leather surface 101 and the base fabric 102 in the bonding area 20, thereby effectively improving the production yield of the artificial leather 100. Combined with Figure 3 During operation, before the base fabric 102 enters the bonding area 20 , the base fabric 102 is first moved around the unfolding roller 3 so that the unfolding roller 3 can flatten the base fabric 102 .

[0029] Ginseng Figure 2 and Figure 5 , the surface material of the unfolding roller 3 is preferably rubber. Since rubber material is light in weight and has a larger friction coefficient than metal material, the base fabric 102 is not easy to slip when driving the unfolding roller 3 to rotate, which is beneficial to the flattening effect of the base fabric 102. In a preferred embodiment, the unfolding roller 3 is provided with an unfolding guide surface 33 in both the first annular groove 31 and the second annular groove 32. The unfolding guide surface 33 includes a first guide surface 331 located in the first annular groove 31 and a second guide surface 332 located in the second annular groove 32.

In a preferred embodiment, the unfolding roller 3 is provided with an angle adjustment mechanism (not shown) for adjusting the inclination angle of the first annular groove 31 and the second annular groove 32. The utility model adjusts the inclination angle of the first annular groove 31 and the second annular groove 32 by providing the angle adjustment mechanism to meet the requirements of different types of base fabrics for different unfolding forces, which is beneficial to improving the versatility of the unfolding roller 3.

[0030] Ginseng Figures 5 to 7 The unwinding roller 3 includes an axis core 34 and a plurality of rotating rings 35 rotatably sleeved on the axis core 34, and a plurality of the rotating rings 35 are stacked together to form the first annular groove 31 and the second annular groove 32. The rotating ring 35 is made of rubber. In a preferred embodiment, the rotating ring 35 includes an annular base fabric contact surface 350 and a first end 351 and a second end 352 arranged opposite to each other.

Along the axial direction of the rotating ring 35, the length L of the positioning convex portion 353 is greater than the depth D of the positioning groove 354. The utility model realizes the assembly between two adjacent rotating rings 35 and the formation of the first annular groove 31 and the second annular groove 32 by providing the positioning convex portion 353 and the positioning groove 354. In this embodiment, the base fabric contact surface 350 is a plane, the circumferential outer surface of the positioning protrusion 353 is also a plane, and the circumferential inner surface of the positioning groove 354 is also a plane. Figure 8The circumferential outer surface of the positioning protrusion 353' is preferably an outwardly convex arc surface, the base fabric contact surface 350' and the outer surface of the positioning protrusion 353' are smoothly connected by arc surfaces, and the circumferential inner surface of the positioning groove 354' is also preferably an inwardly concave arc surface. Such an arrangement can ensure the flattening effect on the base fabric while reducing damage to the base fabric. In a preferred embodiment, the unwinding roller 3 also includes a connecting ring 36 fixed to the shaft core O, and the axial ends of the connecting ring 36 are respectively provided with receiving grooves 361 for receiving the positioning protrusion 353.

[0031] Ginseng Figure 1 , Figure 2 and Figure 4 , the multi-layer material bonding system 300 includes a bonding reinforcement mechanism 4 for pressing the artificial leather surface 101 and the base fabric 102 after bonding. The bonding reinforcement mechanism 4 includes two pressing rollers 41 and 42 arranged opposite to each other, and the bonding reinforcement mechanism 4 forms a pressing area 40 between the two pressing rollers 41 and 42, and the position of one of the two pressing rollers 41 and 42 can be adjusted around the other. The utility model can enhance the bonding effect of the artificial leather surface 101 and the base fabric 102 by setting the two pressing rollers 41 and 42 to press the artificial leather 100 after bonding. In this embodiment, the bonding reinforcement mechanism 4 also includes a rotating connecting member 43 connecting the two pressing rollers 41 and 42, wherein one of the pressing rollers 41 is located at the bottom and its position is fixed, and the other pressing roller 42 is located at the top and its position can rotate around the pressing roller 41 located at the bottom. During the production process, the artificial leather 100 can be pressed by rotating the pressing roller 42 located above downward around the pressing roller 41 located below. At this time, the transfer roller 401 of the transfer frame 400 provides support, so that the bonding and reinforcement of the artificial leather surface 101 and the base fabric 102 are achieved more conveniently.
