[0002] Synthetic leather, also known as artificial leather or imitation leather, is a plastic product that simulates the appearance and feel of natural leather. It is usually made with an impregnated non-woven fabric as the net layer (base cloth) and a microporous polyurethane layer as the grain layer. Synthetic leather has the characteristics of air permeability and moisture absorption, and is closer to natural leather than ordinary artificial leather. In addition, it also has the advantages of chemical resistance, uniform quality, adaptability to mass production and processing, and water resistance, mildew resistance, etc., and has been widely used in many fields. With the continuous progress of technology and the improvement of environmental protection requirements, the synthetic leather industry will have a broader development prospect.

[0003] There are various production methods for synthetic leather, among which the dry process is commonly used.

DETAILED DESCRIPTION

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 2 As shown, a novel synthetic leather laminating device includes a frame 1, a base fabric 2, and a film 3. Rollers 4 for supporting the base fabric 2 are installed at both ends of the frame 1. A pressure roller 17 is installed above the rollers 4 at the tail end of the frame 1. A fixing frame 14 is fixedly connected above the tail end of the frame 1. An electric push rod 15 is installed on the top of the fixing frame 14. A mounting frame 16 is installed at the output end of the electric push rod 15. The pressure roller 17 is installed inside the mounting frame 16. A limiting roller 19 is installed at the head of the frame 1 via an L-shaped frame 18. The limiting roller 19 is at the same height as the center of the rollers 4, and the diameter of the limiting roller 19 is smaller than the diameter of the rollers 4.

[0021] The base fabric 2 first passes the bottom of the limiting roller 19, then goes around the top of the head roller 4 of the frame 1, and then is output from the top of the tail roller 4 of the frame 1, which can ensure that the base fabric 2 is attached to the roller 4 at both ends of the frame 1; the height of the pressure roller 17 can be adjusted by the extension and retraction of the electric push rod 15, and the base fabric 2 and the film 3 are pressed and fixed by the pressure roller 17 in conjunction with the roller 4.

[0022] like Figure 3 and Figure 4 As shown, a support frame 5 is fixedly connected to the middle of the frame 1. A liquid storage tank 6 is installed on the top of the support frame 5. A rotor pump 7 is connected to the lower part of the liquid storage tank 6 near the head of the frame 1. A horizontal pipe 8 is connected to the output end of the rotor pump 7. Multiple discharge pipes 9 are provided at the bottom of the horizontal pipe 8. A scraper 10 located above the base fabric 2 is installed on the inner side of the support frame 5. Multiple triangular prism-structured material distribution blocks 12 are fixedly connected to the scraper 10 near the head of the frame 1. The number of material distribution blocks 12 is the same as the number of discharge pipes 9 and they correspond one-to-one. Two fixing plates 11 are symmetrically provided on the side of the support frame 5 near the tail of the frame 1. A scraper 2 13 is installed between the two fixing plates 11.

[0023] Adhesive is added to the storage tank 6. When the rotor pump 7 is working, the adhesive is transported to the horizontal pipe 8 and then discharged to the surface of the base fabric 2 through the discharge pipe 9. The adhesive can be initially spread evenly during the transport of the base fabric 2 by the material distribution block 25 and the scraper 10. The adhesive can be spread evenly again by the scraper 2 13 to ensure the uniformity of the adhesive coating.

[0024] The vertical plate one 20 is symmetrically fixed on the top of the support frame 5, the height of the vertical plate one 20 is greater than the liquid storage tank 6, and the limiting roller two 21 for limiting the film 3 is installed between the two vertical plate ones 20; the vertical plate two 22 is symmetrically fixed between the vertical plate one 20 and the tail of the rack 1 on both sides of the rack 1, and the guide roller 23 is rotatably installed between the two vertical plate two 22.

[0025] The height of the film 3 during installation is at least flush with the limiting roller two 21, so as to prevent the liquid storage tank 6 from affecting the film 3, and the film 3 is close to the base cloth 2 through the guide roller 23.

[0026] In specific use, the rotor pump 7 delivers the adhesive into the horizontal pipe 8 when working, and then discharges the adhesive to the surface of the base cloth 2 through the discharge pipe 9; the adhesive can be uniformly coated on the surface of the base cloth 2 through the cooperation of the distribution block 25, the scraper one 10 and the scraper two 13; the base cloth 2 and the film 3 are pressed and fixed through the cooperation of the compression roller 17 and the carrier roller 4; and the stability of the connection between the base cloth 2 and the film is effectively improved through coating the adhesive on the base cloth 2.

[0027] The parts not disclosed in the utility model are all prior art, and the specific structure and working principle will not be described again.
