Description

Technical Field

[0001] This invention relates to the field of automotive interior manufacturing, and more particularly to a flame-retardant automotive interior material and its manufacturing process. Background Technology

[0002] The development of the automotive industry is an important indicator of a country's industrial development level, directly reflecting its degree of development. Countries like the United States, Japan, and Germany have a clear advantage in both the quantity and quality of their automotive manufacturing industries. Although my country's automobile production started relatively late, its development speed has been rapid, especially in passenger cars, where the growth rate has been astonishing. The rapid development of the automotive industry has greatly increased the production scale and technology of automotive interior materials. Within the confined environment of a car, interior materials have the most direct contact with people. While some high-end cars use leather for seat upholstery, most automotive interior materials use textiles as raw materials and fabrics. Automotive interior materials mainly include: padding materials, covering materials, and filtering materials. Varieties include: seat fabrics, headliners, door linings, carpets, seat belts, etc. A search revealed that Chinese utility model patent CN214496792U discloses a sizing process for flame-retardant textile production, comprising a housing.

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] This invention provides a flame-retardant automotive interior material and its manufacturing process, including a conveying box 1. A mixing box 2 is fixedly connected to one end of the conveying box 1. A slurry mixing mechanism is fixedly installed inside the mixing box 2. The slurry mixing mechanism includes a second motor 17. Support columns 18 are fixedly connected to the four corners of the top of the mixing box 2. A support plate is fixedly connected between the tops of the four support columns 18. The top of the support plate is fixedly connected to one end of the second motor 17. The output end of the second motor 17 extends to the bottom of the support plate and is fixedly connected to a rotating block 19. Multiple rotating through holes are opened at the top of the rotating block 19. A rotating rod 20 is rotatably connected inside each of the four rotating through holes. A mixing rod 21 is fixedly connected to the bottom of the rotating block 19. Stirring plates 22 are fixedly connected to the outer walls of the four rotating rods 20.

Circular racks 25 are fixedly connected to the outer walls of the circular rotating plates 24. The rotating gears 23 mesh with the circular racks 25. With the combined use of the second motor 17, rotating block 19, stirring rod 21, rotating gear 23, circular racks 25, stirring rod 21, and stirring plates 22, the mixing and stirring effect of the interior preparation slurry is improved, further enhancing the slurry extrusion effect of the interior preparation material. Furthermore, the rotation of the four rotating rods 20 improves the mixing and stirring effect of the interior preparation material slurry. At the top four corners of the conveyor box 1, support columns 3 are fixedly connected. Support plates 4 are fixedly connected between the tops of the four support columns 3.

An extrusion groove is provided at the top of the conveyor box 1. A slurry extrusion frame 7 is fixedly connected inside the extrusion groove. An arc-shaped filter screen is fixedly installed inside the slurry extrusion frame 7. A placement groove is provided at the top of the slurry extrusion frame 7.

A conveying channel penetrating into the interior of the conveying box 1 is opened at one end of the mixing tank 2. After the interior preparation material is poured onto the top of the conveying box 1, it falls onto the slurry extrusion frame 7 and the arc-shaped filter screen. With the cooperation of the hydraulic rod 5 and the arc-shaped extrusion plate 6, the slurry and raw materials can be effectively separated, and the slurry is conveyed into the interior of the mixing tank 2. Under the operation of the electric telescopic rod 12, the adjusting plate 11 and the adjusting slider 10 will move inside the adjusting cylinder 9 until the push cylinder 13 and the arc-shaped cleaning plate 15 move away from the placement groove. At this time, the first motor 14 is energized and started.

A sealing strip is fixedly connected to the outer wall of the push cylinder 13 to improve the sealing effect of the outer wall of the push cylinder 13 and reduce the probability of the slurry entering the connecting box 8.

[0021] The first motor 14, the second motor 17, the third motor, the electric telescopic rod 12, and the hydraulic rod 5 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not elaborate further on them here.

[0022] In summary, the schematic diagram of this flame-retardant automotive interior material and its manufacturing process is shown in the following diagram for actual use; Step 1: First, pour the interior preparation material onto the top of the conveyor box 1 until it falls onto the slurry extrusion frame 7 and the arc filter screen. Then, start the hydraulic rod 5. Under the operation of the hydraulic rod 5, the arc extrusion plate 6 will effectively extrude and slurry the textile raw materials, and effectively separate the slurry and raw materials, and transport the slurry to the interior of the mixing box 2. Step 2: After the slurry enters the mixing tank, the output of the second motor 17 will drive the rotating block 19 to rotate, and the rotation of the rotating block 19 will drive the four stirring rods 21 to rotate. At this time, when the four stirring rods 21 rotate around the rotating block 19, the stirring rods 21 and the stirring plate 22 will rotate through the cooperation of the rotating gear 23 and the ring rack 25, which will further improve the mixing effect of the slurry prepared in the mixing tank. The slurry inside the mixing tank 2 will be mixed and treated by the cooperation of the stirring rods 21 and the stirring plate 22, and then discharged through the discharge pipe 28. As the stirring rod 21 revolves around the rotating block 19, and then rotates on its own axis in the meshing state of the rotating gear 23 and the ring rack 25, the stirring plate 22 drives the stirring plate 22 to fully mix the raw materials for preparing the slurry inside the mixing tank 2. During the rotation of the rotating block 19, the stirring rod 21 and the stirring plate 22 on the outer wall of the stirring rod 21 will rotate synchronously, further improving the mixing effect. Step 3: In this device, the electric telescopic rod 12 will drive the adjusting plate 11 and the adjusting slider 10 to move inside the adjusting cylinder 9 until it drives the pushing cylinder 13 and the arc-shaped cleaning plate 15 to move away from the placement groove. At this time, the first motor 14 will be powered on and started. The output end of the first motor 14 will drive the arc-shaped cleaning plate 15 to rotate and clean the outer wall of the slurry extrusion frame 7 and the arc-shaped filter screen, effectively avoiding the occurrence of impurity residue.
