Pre-pressing and compounding of interior materials is an important link in the automotive interior processing. By pre-pressing the interior materials, it can meet the requirements of subsequent processing, thereby improving the product quality and production efficiency. As a key device for pre-pressing and compounding of interior materials, the performance of the pre-pressing device directly affects the processing quality and production efficiency of interior materials.

In addition, coating silicone oil is an important measure to keep the surface of the pre-pressing rollers smooth and reduce friction. However, the traditional coating methods often have problems such as uneven coating and easy loss of silicone oil, which also bring certain troubles to the processing of interior materials.

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0023] Example 1, as shown in Figure 1 , Figure 2 and Figure 3 shown, a pre-pressing device for automotive interior materials includes a processing table 1, a middle part of the upper end of the processing table 1 is fixedly connected with an isolation cover 4, a feeding belt 11 is arranged in the middle of the upper end of the processing table 1, a middle part of the inner surface of the upper end of the isolation cover 4 is rotatably connected with a pre-press roller 6, an upper end of the press roller cleaning structure 2 is fixedly connected with a driving motor 5, an output end of the driving motor 5 is in transmission connection with the pre-press roller 6 through a transmission belt, a press roller cleaning structure 2 is arranged on a right part of the inner surface of the isolation cover 4, a middle part of the rear end of the processing table 1 and the inner surface of the isolation cover 4 are jointly provided with an airflow circulation structure 3, and a front end of the processing table 1 is fixedly connected with a control console 7.

[0024] It should be particularly noted that the above-mentioned feeding belt 11 is a commonly used feeding device in the prior art, and a motor is arranged inside it to drive a belt pulley to rotate, and the belt drives the material.

[0025] Furthermore, in order to realize the pre-pressing operation of automotive interior materials, refer to Figure 2 , the pre-press roller 6 includes a central shaft 62 rotatably connected with the inner surface of the isolation cover 4, a part of the outer surface of the central shaft 62 located inside the isolation cover 4 is fixedly connected with a drum 61, a rear end of the central shaft 62 and an output end of the driving motor 5 are in transmission connection through a belt, and a plurality of air holes 63 communicating with its inner cavity are annularly distributed on both the front part and the rear part of the outer surface of the central shaft 62.

[0026] The central shaft 62 is driven by a transmission belt to rotate by the driving motor 5. Then, the roller 61 is driven to rotate. During the rotation of the roller 61, the automotive interior materials fed by the feeding belt 11 are pre-pressed to make them fit tightly, improving the subsequent processing quality. As the roller 61 continues to rotate, the materials on the feeding belt 11 are evenly pressed, ensuring a uniform pre-pressing effect.

[0027] Further, to achieve the compounding of the sponge, the adhesive film, and the leather, refer to Figure 3 and Figure 4 , a heating controller 611 is fixedly connected to the inner surface of the roller 61, an electric heating wire 612 connected to the heating controller 611 through a wire is fixedly connected to the inner cavity of the roller 61, an air slip ring 613 sleeved outside the rear air hole 63 is rotatably connected to the rear part of the outer surface of the roller 61, and a second connecting pipe 614 communicating with the air flow circulation structure 3 is fixedly connected to the lower part of the outer surface of the air slip ring 613.

[0028] The above heating controller 611 is a conventional electric heating controller. Under the action of the heating controller 611, the electric heating wire 612 can continuously generate heat, and the heat is transferred to the surfaces of the sponge, the adhesive film, and the leather through the roller 61, making them heat-softened and enhancing the bonding effect.

[0029] During the operation of this embodiment, first, the automotive interior materials are fed into the pre-pressing device by the feeding belt 11. Then, the driving motor 5 is started to drive the central shaft 62 to rotate, and the roller 61 rotates accordingly to pre-press the materials. At the same time, the heating controller 611 heats the electric heating wire 612, and the heat is transferred through the roller 61, making the sponge, the adhesive film, and the leather heat-softened, ensuring the tight compounding of the three, improving the overall processing quality, realizing the efficient pre-pressing and compounding of the automotive interior materials, enhancing the durability and aesthetics of the product, and meeting the requirements of modern production processes.

[0030] It should be particularly noted that the above control console 7 is a conventional controller, and this structure has been widely used in the prior art. In the present invention, only its function of controlling the start and stop of the electrical equipment in the control device is utilized, and its internal structure, operating principle, wiring, and control method will not be elaborated further.

[0031] Embodiment 2: Based on Embodiment 1, this embodiment is provided with two cleaning cylinders 32 and cleaning brushes 33 on their outer surfaces in the inner cavity of the isolation cover 4. When the automotive interior materials pass through, they are secondarily pre-pressed in cooperation with the limiting rollers 41 to ensure that their surfaces are flat and wrinkle-free. Moreover, the rotation of the cleaning cylinders 32 is driven by the frictional force between the interior materials and the cleaning cylinders 32, and then the surfaces are cleaned by the cleaning brushes 33 to remove impurities and improve the processing accuracy. Further, through the cooperation of the second connecting groove 323 opened at the lower part of the inner cylinder 321 and the first connecting groove 322, the dust on the surface of the interior material is collected and discharged by the action of the dust collection box 31 and the first connecting pipe 34, keeping the working environment clean, ensuring that the surface of the interior material is dust-free, improving the product quality. At the same time, the hot air in the heating wire 612 is sent into the cleaning cylinder 32 on the right side by the action of the air slip ring 613 and the second connecting pipe 614 to further heat the interior material, making its internal structure more stable, promoting the full penetration of silicone oil, enhancing the adhesion between layers, ensuring that the composite interior material is not easily delaminated during use, and extending the service life.

[0032] Specifically, to achieve the cleaning of the surface of the interior material and assist the action of silicone oil, refer to Figure 4 , the air flow circulation structure 3 includes a dust collection box 31 fixedly connected to the rear end of the processing table 1. The front end of the dust collection box 31 is fixedly connected with two first connecting pipes 34 symmetrically left and right. The ends of the two first connecting pipes 34 far away from the dust collection box 31 both extend to the front end of the isolation cover 4 and are rotatably connected with a cleaning cylinder 32 rotatably connected to the inner surface of the isolation cover 4. The outer surfaces of the two cleaning cylinders 32 are fixedly connected with cleaning brushes 33. The inner surface of the isolation cover 4 is respectively rotatably connected with limiting rollers 41 symmetrically along the two cleaning cylinders 32. The cleaning cylinder 32 on the left is communicated with the second connecting pipe 614.

[0033] The air in the two cleaning cylinders 32 is extracted through the action of the dust collection box 31, and then the surface of the interior material in contact with the cleaning cylinder 32 is cleaned to remove dust, ensuring the cleanliness before bonding; A dust-proof cap that can ventilate is fixed at the rear end of the cleaning cylinder 32 on the left, that is, the feeding side, to prevent external dust from being sucked into the cleaning cylinder 32 when the air flows. The rear end of the cleaning cylinder 32 on the left is communicated with the inner cavity of the central shaft 62 through the second connecting pipe 614 and the air slip ring 613, so as to preheat the air in the cleaning cylinder 32 by using the waste heat in the central shaft 62, improving the infiltration effect of silicone oil and the adhesion of the adhesive film.

[0034] Further, to achieve the treatment of the dust on the surface of the interior material, refer to Figure 5 and Figure 6 , the outer surface of the cleaning cylinder 32 is rotatably connected to the inner surface of the isolation cover 4 through a connecting shaft. The inner surface of the cleaning cylinder 32 is rotatably connected with an inner cylinder 321 fixedly connected to the adjacent first connecting pipe 34. A second connecting groove 323 is opened at the lower part of the outer surface of the inner cylinder 321. A number of first connecting grooves 322 matching the size of the second connecting groove 323 are annularly distributed on the outer surface of the cleaning cylinder 32.

[0035] The cleaning cylinder 32 will rotate under the action of friction following the movement of the interior material, thereby driving the cleaning brush 33 to clean on the surface of the interior material. Further, during the rotation process, the second communication groove 323 and the lower first communication groove 322 will communicate periodically. At this time, suction will be generated at the lower part of the first communication groove 322, thereby sucking the dust on the surface of the interior material into the inner cylinder 321 and sending it into the dust collection box 31 for temporary storage through the first communication pipe 34.

[0036] Further, to achieve the absorption and temporary storage of dust, refer to Figure 5 , a number of fans 311 are fixedly connected in a linear distribution at the rear end of the dust collection box 31, a dust filtering baffle 312 is fixedly connected to the rear part of the inner surface of the dust collection box 31, a third communication pipe 313 connecting the pressing roller cleaning structure 2 and the inner cavity of the dust collection box 31 is fixedly connected to the upper end of the dust collection box 31, and both first communication pipes 34 communicate with the inner cavity of the dust collection box 31.

[0037] The fans 311 exhaust air outwards, forming a negative pressure with the inner cavity of the cleaning cylinder 32 through the first communication pipe 34, thereby extracting the dust on the surface of the interior material through the cleaning cylinder 32 and sucking and temporarily storing the dust in the dust collection box 31 to avoid secondary pollution; at the same time, the dust filtering baffle 312 installed inside the dust collection box 31 can block the outflow of dust, and a cabinet door is also opened on one side of the dust collection box 31, which can facilitate the regular cleaning of dust, keep the inside of the equipment clean, and ensure the long-term and efficient operation of the system.

[0038] Embodiment 3. On the basis of Embodiment 2, this embodiment further uses the electric brush 22 installed in the installation groove 25 to clean the surface of the roller 61, and further scrapes off part of the dust through the scraper 23 arranged in the installation groove 25, reducing the dust adhering to the surface of the central shaft 62 and avoiding the contamination of the interior material surface by these dust and debris during the processing, thereby improving the product quality and processing efficiency; At the same time, through the action of the constant pressure oil pump 243 in the oil storage cavity 241 on the arc-shaped relay cavity 244, the silicone oil is evenly sent out through the slit 242 opened in the arc-shaped relay cavity 244 and smeared on the surface of the roller 61 to form a uniform thin film, enhancing the adhesion effect, ensuring the tight combination of the interior material and the base material, and improving the stability and durability of the overall structure.

[0039] Specifically, to achieve the cleaning of the surface of the roller 61 and the coating of new silicone oil, refer to Figure 7 , the pressing roller cleaning structure 2 includes an arc-shaped block 21 fixedly connected to the inner surface of the isolation cover 4. An installation groove 25 is opened in the upper part of the arc-shaped block 21 close to the pre-pressing roller 6. A silicone oil coating assembly 24 is arranged in the lower part of the arc-shaped block 21 close to the pre-pressing roller 6. An electric brush 22 is fixedly installed on the upper part of the inner surface of the installation groove 25, and a number of scrapers 23 are arranged on the lower part of the inner surface of the installation groove 25.

[0040] The above-mentioned electric brush 22 is a power cleaning brush with a built-in motor. Its motor side and drive shaft are installed on the inner surface of the installation groove 25, and the outer surface of the movable side is provided with a brush. The brush rotates at a high speed under the drive of the motor to clean the fine dust on the surface of the roller 61.

[0041] Further, to clean the silicone oil cleaned by the electric brush 22, refer to Figure 8 , on the side of the inner surface of the installation groove 25 away from the pre-pressure roller 6, an air chamber 251 communicating with the third connecting pipe 313 is opened. A number of third connecting grooves 252 connecting the installation groove 25 and the air chamber 251 are linearly distributed on the side of the air chamber 251 close to the installation groove 25.

[0042] The third connecting pipe 313 is connected to the air chamber 251 to form an air flow channel. The cleaned silicone oil and dust are inhaled into the third connecting pipe 313 through the third connecting grooves 252 and finally enter the dust collection box 31 for temporary storage, ensuring the cleanliness of the surface of the roller 61 and improving the bonding effect.

[0043] Further, to clean the impurities tightly attached to the surface of the roller 61, refer to Figure 8 and Figure 9 , mounting holes 232 are symmetrically opened at the front and rear ends of the scraper 23. The inner surface of the mounting holes 232 and the inner surface of the rotating shaft 231 are jointly rotatably connected to a rotating shaft 231 fixedly connected to the inner wall of the installation groove 25. A hairspring 233 fixedly connected to the inner surfaces of the two side mounting holes 232 is fixedly connected to the outer surface of the rotating shaft 231.

[0044] The hairspring 233 is an elastic scraping piece. Under the action of the hairspring 233, it is closely attached to the surface of the roller 61, effectively scraping off stubborn impurities. During the rotation of the roller 61, the dust and impurities are ejected from the surface through the elastic action of the hairspring 233 to ensure thorough cleaning. At the same time, the material of the scraper 23 is selected as a wear-resistant material to extend the service life and maintain a long-term high-efficiency cleaning effect.

[0045] Further, to evenly supplement silicone oil to the surface of the roller 61, refer to Figure 8 and Figure 10 , the silicone oil coating assembly 24 includes an oil storage cavity 241 opened in the inner cavity of the arc-shaped block 21. A constant pressure oil pump 243 is fixedly connected to the bottom wall of the inner surface of the oil storage cavity 241. A number of arc-shaped relay cavities 244 communicating with the output pipe of the constant pressure oil pump 243 are circumferentially arranged on the side of the arc-shaped block 21 close to the pre-pressure roller 6. A semi-circular block 245 is slidably connected to the inner surface of each of the number of arc-shaped relay cavities 244 through a limit sliding groove. A compression spring 246 fixedly connected to the inner wall of the arc-shaped relay cavity 244 is fixedly connected to one end of each of the number of semi-circular blocks 245 close to the oil storage cavity 241. Conical slits 242 communicating with the outer surface of the arc-shaped block 21 are opened on the side of the inner surface of each of the number of arc-shaped relay cavities 244 away from the compression spring 246.

[0046] The constant-pressure oil pump 243 can evenly send the silicone oil in the oil storage cavity 241 into each arc-shaped relay cavity 244. When the silicone oil in the arc-shaped relay cavity 244 is under a certain pressure, it will squeeze the semi-circular block 245 to move it in the direction of the compression spring 246. At this time, the compression spring 246 is compressed by the force. Further, when the semi-circular block 245 leaves the position where the slit 242 is located, the silicone oil will seep out through the slit 242 and come into full contact with the surface of the drum 61, forming a uniform oil film, effectively lubricating and protecting the surface, preventing wear, and ensuring the smooth operation of the equipment; Further, the silicone oil follows the rotation of the drum 61 and is coated on the surface of the interior trim material, forming a dense protective layer, reducing the frictional resistance, extending the service life of the interior trim material, and at the same time keeping the equipment running efficiently and improving the overall performance.
