[Technical field]

[0001] The utility model relates to a multifunctional laminating system and an artificial leather production system. The artificial leather production system comprises the multifunctional laminating system. [Background technology]

[0002] As a surface decoration material, leather is widely used in many fields such as automobiles and home decoration. Common leathers include genuine leather, polar artificial leather such as polyvinyl chloride (PVC) artificial leather, non-polar artificial leather such as thermoplastic polyolefin elastomer (TPO) artificial leather, polyurethane (PU) artificial leather, etc. Genuine leather is gradually replaced by artificial leather due to its high price and environmental pollution.

[0003] Taking PVC artificial leather as an example, the PVC artificial leather used for seat surface decoration materials usually includes a paint layer, a PVC surface layer and a base fabric layer. The PVC surface layer usually includes an adhesive layer, and the base fabric layer is used to enhance the mechanical properties of the PVC artificial leather and has a supporting effect. In the production process of PVC artificial leather, bonding equipment is required to bond the PVC surface layer and the base fabric layer. Different types of PVC artificial leather sometimes choose different types of base fabrics, and there are differences in the physical and mechanical properties of different base fabrics. For example, the tensile properties of polyester base fabric are better, but the strength of suede base fabric is very high, and its tensile properties are relatively poor. There is no bonding equipment in the prior art that can be used for both the bonding of PVC surface fabric and polyester base fabric, and the bonding of PVC surface fabric and suede base fabric.

[0004] Therefore, it is hoped to propose a new technical solution to solve the above technical problems. [Contents of the utility model]

[0005] The technical problem to be solved by the utility model is to provide a multifunctional laminating system and an artificial leather production system, which have strong versatility.

[0006] In order to solve the above technical problems, the utility model can adopt the following technical solutions: a multifunctional laminating system, which is used for laminating an artificial leather surface and a base fabric, the multifunctional laminating system comprises a laminating mechanism, the laminating mechanism comprises two laminating rollers arranged opposite to each other, and the laminating mechanism forms a laminating area between the two laminating rollers. The multifunctional laminating system comprises a rotatable unfolding roller and a non-rotatable smooth roller, the unfolding roller is used to guide the base fabric to the laminating area and has an inclined annular groove on its surface, and the smooth roller is used to guide the base fabric to the laminating area and has a smooth and flat surface.

[0007] In a preferred embodiment, along the axial direction of the unfolding roller, the annular groove includes a plurality of first annular grooves located on one side of the unfolding roller and a plurality of second annular grooves located on the other side of the unfolding roller, and the inclination directions of the plurality of first annular grooves and the inclination directions of the plurality of second annular grooves are axially symmetrical.

[0008] In a preferred embodiment, the surface material of the unwinding roller and the surface material of the smooth roller are both rubber.

[0009] In a preferred embodiment, the unrolling roller and the smooth roller are arranged on the same side of the laminating area, and the smooth roller is farther away from the laminating area than the unrolling roller.

[0010] In a preferred embodiment, the multifunctional laminating system comprises a rotatable supporting roller located between the smooth roller and the laminating area.

[0011] In a preferred embodiment, the two laminating rollers are arranged up and down, the unfolding roller and the smooth roller are both located on the upper side of the laminating area, the outer common tangent line of the unfolding roller and the laminating roller located above and located below will not pass through the supporting roller, and the outer common tangent line of the smooth roller and the laminating roller located above and located below passes through the supporting roller.

[0012] In a preferred embodiment, the position of the supporting rollers is adjustable.

[0013] In a preferred embodiment, the multifunctional laminating system includes a tension adjusting mechanism for adjusting the tension of the base fabric in real time.

[0014] In a preferred embodiment, the multifunctional laminating system includes a laminating and reinforcing mechanism for pressing the artificial leather surface and the base fabric after laminating.

[0015] In order to solve the above technical problems, the present invention can also adopt the following technical solution: an artificial leather production system, which includes an artificial leather surface production system and the multifunctional bonding system described in any one of the above embodiments.

[0016] Compared with the prior art, the utility model has the following beneficial effects: by setting a rotatable unfolding roller and a non-rotatable smooth roller, more types of base fabrics can be smoothly guided to the bonding area and well bonded with the artificial leather surface, thereby improving the versatility of the multifunctional bonding system and the production yield of the product. When the tensile performance of the base fabric is relatively good, such as a polyester base fabric, a rotatable unfolding roller can be selected to flatten the base fabric and guide it to the bonding area; when the tensile performance of the base fabric is relatively poor, such as a suede base fabric, a non-rotatable smooth roller can be selected, and the base fabric can slide on the smooth roller. Due to the large tension, the base fabric will not wrinkle, so it can be smoothly guided to the bonding area.

[0023] 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.

[0024] Ginseng Figure 1 and Figure 2 The 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 multifunctional laminating system 300 and a transfer rack 400. The artificial leather surface production system is used to produce the artificial leather surface 101, the base fabric unwinding mechanism 200 is used to place the base fabric roll wound by the base fabric 102, the multifunctional laminating system 300 is used to laminate the artificial leather surface 101 and the base fabric 102, the transfer rack 400 is used to transfer the laminated artificial leather 100 to the next process, such as a drying process, and the transfer rack 400 includes a plurality of transfer rollers 401.

[0025] Ginseng Figures 1 to 5 The multifunctional laminating system 300 comprises a support 301, a laminating mechanism 1, a rotatable unrolling roller 2 and a non-rotatable smooth roller 3. The laminating mechanism 1, the unrolling roller 2 and the smooth roller 3 are all mounted on the support 301. The laminating mechanism 1 comprises two laminating rollers 11 and 12 arranged opposite to each other, and the laminating mechanism 1 forms a laminating area 10 between the two laminating rollers 11 and 12. Figure 6 The unrolling roller 2 is used to guide the base fabric 102 to the bonding area 10 and has an inclined annular groove 21 on its surface. The smooth roller 3 is used to guide the base fabric 102 to the bonding area 10 and has a smooth and flat surface. The utility model provides the rotatable unrolling roller 2 and the non-rotatable smooth roller 3 to achieve smooth guidance of more types of base fabrics to the bonding area 10 and good bonding with the artificial leather surface 101, thereby improving the versatility of the multifunctional bonding system 300 and the production yield of the product. When the tensile properties of the base fabric 102 are relatively good, such as a polyester base fabric, the rotatable unfolding roller 2 can be selected to flatten the base fabric 102 and guide it to the bonding area 10; when the tensile properties of the base fabric 102 are relatively poor, such as a suede base fabric, the non-rotatable smooth roller 3 can be selected, and the base fabric 102 can slide on the smooth roller 3. Due to the large tension, the base fabric 102 will not wrinkle, and can be guided smoothly to the bonding area 10.

[0026] Ginseng Figure 1 and Figure 6, the surface material of the unfolding roller 2 and the surface material of the smooth roller 3 are both rubber. Since the rubber material is light in weight and has a larger friction coefficient than that of metal materials, the base fabric 102 is not easy to slip when driving the unfolding roller 2 or the smooth roller 3 to rotate, which is beneficial to the flattening effect of the base fabric 102. Preferably, the unfolding roller 2 includes a first mandrel 22 and a plurality of rubber rings 23, 24 rotatably mounted on the first mandrel 22, and the annular groove 21 is formed between two adjacent rubber rings 23, 24. Of course, in other embodiments, the plurality of rubber rings 23, 24 can also be replaced by a rubber roller, and the plurality of annular grooves 21 can be formed on the rubber roller, which can also achieve the purpose of the invention. Preferably, the smooth roller 3 includes a second mandrel 31 and a rubber jacket 32.

[0027] Continue to participate in Figure 6 , along the axial direction O of the unfolding roller 2, the annular groove 21 includes a plurality of first annular grooves 211 located on one side of the unfolding roller 2 and a plurality of second annular grooves 212 located on the other side of the unfolding roller 2, and the inclination directions of the plurality of first annular grooves 211 and the inclination directions of the plurality of second annular grooves 212 are axially symmetrical. The utility model can achieve uniform flattening of the base fabric 102 by setting the inclination directions of the plurality of first annular grooves 211 and the plurality of second annular grooves 212 to be axially symmetrical.

[0028] Ginseng Figures 1 to 3 , the unrolling roller 2 and the smooth roller 3 are arranged on the same side of the laminating area 10, and the smooth roller 3 is farther from the laminating area 10 than the unrolling roller 2. Of course, in other embodiments, the unrolling roller 2 can also be arranged farther from the laminating area 10 than the smooth roller 3. Further, the multifunctional laminating system 300 includes a rotatable supporting roller 4 located between the smooth roller 3 and the laminating area 10, and the supporting roller 4 is installed on the bracket 301. By setting the supporting roller 4, it can provide support for the base fabric 102 and increase its tension, which is conducive to preventing the base fabric 102 from loosening and wrinkling. The two laminating rollers 11 are arranged up and down, the unrolling roller 2 and the smooth roller 3 are both located above and to the side of the laminating area 10, the outer common tangent line of the unrolling roller 2 and the laminating roller 11 located above and located below will not pass through the supporting roller 4, and the outer common tangent line of the smooth roller 3 and the laminating roller 11 located above and located below will pass through the supporting roller 4. Such an arrangement can overcome the defect that the base fabric 102 is easily loosened and wrinkled due to the long distance between the smooth roller 3 and the laminating area 10, while not hindering the use of the unrolling roller 2. In a preferred embodiment, the position of the supporting roller 4 can be adjusted, so as to improve the flexibility of operation and production efficiency.

[0029] Ginseng Figure 1 , Figure 2 and Figure 4 The multifunctional laminating system 300 includes a tension adjusting mechanism 5 for adjusting the tension of the base fabric 102 in real time, and the tension adjusting mechanism 5 is installed on the bracket 301. The tension adjusting mechanism 5 can ensure that the base fabric 102 enters the laminating area 10 with appropriate tension and is laminated with the artificial leather surface 101.

[0030] Continue to participate Figure 1 , Figure 2 and Figure 4 The multifunctional laminating system 300 includes a laminating reinforcement mechanism 6 for pressing the artificial leather surface 101 and the base fabric 102 after laminating, and the laminating reinforcement mechanism 6 is installed on the bracket 301. The laminating reinforcement mechanism 6 is used to strengthen the laminating effect of the artificial leather surface 101 and the base fabric 102 after laminating. The laminating reinforcement mechanism 6 is installed between the laminating mechanism 1 and the transfer frame 400.
