[0036] Preferred embodiments of the invention will now be described in more detail. While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] This invention provides a multifunctional laminating machine for multilayer fabric composite processing, comprising:

[0038] The front section is a multi-layered duplex structure. Each layer of the front section includes multiple fabric rolling rollers arranged along the axial direction. There is a viscous trough between adjacent fabric rolling rollers. Above the viscous trough, there are two liquid dispensing rollers arranged vertically. Foam baffles are provided on one or both sides of the liquid dispensing rollers.

[0039] A mucus delivery structure connected to a mucus tank and a foam baffle.

[0040] The body section is a box structure, and the interior of the body section includes multiple heating rollers. The discharge end of the head section is connected to the feed end of the body section.

[0041] At the rear of the vehicle, the feed end is connected to the discharge end of the vehicle body. The rear of the vehicle includes multiple cooling rollers, and the discharge end of the rear of the vehicle is connected to the finished fabric roll roller.

[0042] Specifically, the multi-functional laminating machine includes a head section, a body section, and a tail section. The head section has a multi-layered composite structure, with each layer having one or more fabric rolling rollers. A viscous trough and a liquid dispensing roller are placed between the rolling rollers, and foam baffles are set on one or both sides of the liquid dispensing roller. This allows the fibers or fabric to be coated with viscous or foam adhesive as the liquid dispensing roller rotates. Then, after each layer of material is laminated together, the composite material containing a certain amount of moisture is heated and dried through the heating and cooling of the body section and the tail section to remove moisture and achieve a hot melt lamination process. Finally, the composite material is wound up by the finished fabric rolling roller.

[0043] Optionally, a first two-roller rolling mill is provided between each layer of fabric rolls, and a second two-roller rolling mill is provided at the feed end and discharge end of the body section, respectively.

[0044] Specifically, a first two-roller press is set between the two layers of fabric rolls. The upper and lower layers of fabric with adhesive residue adhere to the upper and lower sides of the fabric layer on the first two-roller press, respectively, to achieve fabric layer bonding. Then, the fabric layer is squeezed by a second two-roller press before and after entering the car body section to increase the bonding strength and ensure heating and cooling effects.

[0045] Optionally, the foam baffles are arranged in an inverted octagon shape on both sides of the liquid supply roller.

[0046] Specifically, the foam baffle can be set on one or both sides of the liquid application roller, and the foam baffle is detachable. When the viscous liquid tank is used to apply the viscous liquid to the material in a full coating manner, the foam baffle does not function. When the viscous liquid tank is used to apply the viscous liquid to the material in a foam coating manner, the generated foam-like adhesive liquid is transported to the foam baffle through the pipeline. The liquid application roller rotates in the same direction as the fiber material or fabric material, and the adhesive liquid is applied to the front or back of the material through the foam baffle.

[0047] Optionally, the front section may also include a tracked conveyor.

[0048] Specifically, flexible discontinuous materials can be placed on the tracked conveyor. When the track and the fabric roll shaft of the front part move synchronously towards each other, the discontinuous materials can be combined with other fabrics or fibers.

[0049] Optionally, the viscous transport structure includes a viscous storage tank and a foam generator, wherein the first outlet of the viscous storage tank is connected to a viscous trough, and the second outlet of the viscous storage tank is connected to a foam baffle via the foam generator.

[0050] Specifically, the viscous conveying structure has two conveying methods. One is to send the pre-mixed adhesive liquid to the viscous storage tank and then directly to the viscous tank through the first outlet to implement the full coating process. The other is to send the adhesive liquid to the foam generator through the second outlet, so that the adhesive liquid changes from liquid to foam. The foam adhesive liquid is then sent to the foam baffle to implement the foam coating process.

[0051] Optionally, the two liquid supply rollers are a rubber roller and a steel roller, respectively, with the outer surface of the steel roller being uneven.

[0052] Specifically, two liquid-dispensing rollers are installed on each viscous tank. The liquid-dispensing rollers are set vertically, and the fabric passes between the two liquid-dispensing rollers. The liquid-dispensing rollers are configured as a rubber roller and a steel roller. The surface of the steel roller is engraved with patterns and dots to form a concave-convex surface. When the fabric is coated in real time through the liquid-dispensing rollers, the surface of the fabric layer can form discontinuous dots of viscous liquid, which can reduce the amount of viscous liquid applied and give the composite fabric good air permeability.

[0053] Optionally, it also includes an operating console and a transmission unit that are positioned opposite each other.

[0054] Specifically, this multi-functional laminator can be configured as a right-hand device, with the control panel located on the right side of the entire laminator, and auxiliary facilities such as the transmission system installed on the left side. In addition, the control panel at the front of the vehicle is located outside the right-hand operating aisle, while the displays on the control panels at the body and rear of the vehicle are also located on the right side.

[0055] Optionally, the wall of the slime tank has a sandwich structure, and a heating tube is installed inside the jacket.

[0056] Optionally, the side walls of the body box are made of double-layer metal plates with an insulation layer between them.

[0057] Specifically, the slurry tank is designed as a jacketed structure consisting of inner and outer layers. The jacket contains temperature-controlled warm water to control the viscosity of the adhesive liquid in the slurry tank. A U-shaped indirect heating pipe can also be installed inside the jacket. The body part is used to heat and dry the composite material. A metal plate filled with aerogel insulation layer is used to make the body part more heat-insulating.

[0058] Optionally, all heating rollers rotate in the same direction, while all cooling rollers rotate in different directions.

[0059] Specifically, when the composite material enters the vehicle body, the heating rollers are used to change the direction of fabric insertion, and all the heating rollers set in a straight line rotate synchronously and in the same direction; while when the composite material enters the rear of the vehicle, all the cooling rollers rotate in different directions, increasing the total length and time of passage and enhancing the cooling effect.

A first movable foam baffle 19, a second movable foam baffle 20, a third movable foam baffle 21 and a fourth movable foam baffle 22 are respectively provided on both sides of the fifth liquid supply roller 13 and the sixth liquid supply roller 14.

[0063] The mucus delivery structure is connected to all mucus tanks, all foam baffles, and all movable foam baffles.

[0064] The body section is a box structure, which includes a heating box 25 and five internal heating rollers, namely the first heating roller 26, the second heating roller 27, the third heating roller 28, the fourth heating roller 29 and the fifth heating roller 30. The discharge end of the car head section is connected to the feed end of the body section.

[0065] At the rear of the vehicle, the feed end is connected to the discharge end of the vehicle body. The rear of the vehicle includes multiple cooling rollers, which form a cooling system 31. The discharge end of the rear of the vehicle is connected to the finished fabric roll roller 36.

[0066] In this embodiment, a first two-roller rolling mill 32 is placed in the gap between the two layers of fabric rolling rollers, a second two-roller rolling mill 33 and a third two-roller rolling mill 34 are placed at the feeding end of the body part, and a fourth two-roller rolling mill 35 is placed at the discharge end of the body part.

[0067] In this embodiment, the movable foam baffles on both sides of the fifth liquid supply roller 13 and the sixth liquid supply roller 14 are arranged in an inverted octagon shape.

[0068] In this embodiment, the front section also includes a tracked conveyor 37.

[0069] In this embodiment, the mucus conveying structure includes a mucus storage tank 23 and a foam generator 24. The first outlet of the mucus storage tank 23 is connected to the first mucus tank 6, the second mucus tank 9 and the third mucus tank 12. The second outlet of the mucus storage tank 23 is connected to all the foam baffles and all the movable foam baffles through the foam generator 24.

[0070] In this embodiment, the first liquid supply roller 7 and the second liquid supply roller 8 are a rubber roller and a steel roller, respectively, and the outer surface of the steel roller is uneven. The liquid supply roller above each viscous trough can be configured with the same structure as the first liquid supply roller 7 and the second liquid supply roller 8.

[0071] In this embodiment, an operating console portion and a transmission portion are also included, which are arranged opposite to each other.

[0072] In this embodiment, the walls of the first slime tank 6, the second slime tank 9, and the third slime tank 12 are all sandwich structures, made of stainless steel, and a heating tube is installed inside the jacket.

[0073] In this embodiment, the side wall of the body box is a double-layer metal plate with a heat insulation layer filling between the metal plates.

[0074] In this embodiment, all heating rollers rotate in the same direction, while all cooling rollers rotate in different directions.

The body of the heating box 25 is made of insulated steel sheet, and an aerogel insulation layer is filled between the two steel plates. When the first viscous tank 6 is coated using a full coating process, the fabric layer to be laminated will adhere the adhesive liquid on the surface of the first liquid roller 7 to the back of the fabric layer when it comes into contact with the first liquid roller 7. This adhesive liquid will then be deposited onto the back of the fabric layer and laminated with another fabric layer that enters in the same direction. In the full coating process, the first foam baffle 15 and the second foam baffle 16 are not used. When a foam coating process is used, the viscous liquid in the viscous storage tank 23 passes through the foam generator 24, and the resulting foam is directly transported through pipes to the upper liquid roller and the lower foam baffle or movable foam baffle. In the foam coating process, the viscous tank is always empty.

[0076] The fifth roll of fabric 5 in the head section is positioned not only for multi-layer material composites, but also for laminating a polymer film to the outermost layer of the composite material, enabling the film to impart more properties to the multi-layer composite material.

[0077] This multi-functional composite machine can also be modified to be a left-handed device, with the control panel on the left and the transmission and auxiliary facilities on the right. The display screen, electrical control cabinet, emergency stop switch, etc. of the front part are placed on the left. The operation buttons of the front, body and rear parts are placed on the left side of the machine. The personnel movement and inspection routes are all on the left side of the machine. The placement of the viscous storage tank 23 and foam generator 24 in the front part are also adjusted accordingly.
