Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric coating technology, and in particular to a flame-retardant coating device for automotive nonwoven fabric. Background Technology

[0002] Nonwoven fabric, also known as non-woven textile, is a sheet material made from short or long textile fibers that are web-formed by airflow or mechanical means and then reinforced by methods such as needle punching, hydroentangling, and thermal bonding. It is characterized by its lightweight, breathability, and low cost. The flame-retardant coating device for automotive nonwoven fabrics is specifically designed for processing nonwoven fabrics in the automotive industry. Its core function is to uniformly coat the surface of automotive nonwoven fabrics with flame-retardant coatings, giving the nonwoven fabric flame-retardant properties to meet the safety requirements of automotive interior components.

[0003] Existing devices typically use a frame to mount coating components and a scraper. During use, the non-woven fabric is first conveyed to the coating area. After the coating is applied to the surface of the non-woven fabric through the discharge structure, the coating is smoothed by the scraper. When adjusting the height of the scraper, only simple bolts or shims are used, resulting in poor adjustment accuracy. This leads to large deviations in coating thickness and may result in substandard flame retardant performance. It is difficult to ensure consistency in mass production, which significantly increases production costs and affects product quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a flame-retardant coating device for automotive non-woven fabrics, which aims to improve the problem that relying solely on simple bolts or shims when adjusting the scraper height results in large deviations in coating thickness and potential failure to meet flame-retardant performance standards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant coating device for automotive non-woven fabric, comprising a main board, a bracket fixedly connected to the upper surface of the main board, a housing fixedly connected to the upper surface of the bracket, a motor fixedly connected to the inner wall of the housing, a gear one fixedly mounted at the output end of the motor, a gear two meshing with the tooth end of the gear one, the outer wall of the gear two rotatably connected to the inside of the bracket, a threaded rod fixedly connected to the lower surface of the gear two, the bottom end of the threaded rod rotatably connected to the upper surface of the main board, a scraper threadedly connected to the outer wall of the threaded rod, a fixed rod slidably connected to the inside of the scraper, the top end of the fixed rod fixedly connected to the inner top wall of the bracket, the bottom end of the fixed rod fixedly connected to the upper surface of the main board, and a spraying assembly mounted on the upper surface of the main board.

[0006] The above technical solution works as follows: when the motor is started, it drives the first gear at the output end to rotate. When the first gear rotates, the second gear, which is connected to the gear end, drives the threaded rod to rotate synchronously. As the threaded rod rotates, it adjusts the height of the scraper to scrape the flame-retardant layer on the surface of the non-woven fabric. This allows for precise adjustment of the scraper height, ensuring accurate coating thickness, meeting flame-retardant performance standards, ensuring consistency in mass production, avoiding batch differences, reducing paint waste and scrap rate, lowering costs, and ultimately guaranteeing product quality.

[0007] Preferably, the spraying assembly includes a paint applicator, the lower surface of which is fixedly connected to the upper surface of the main board, and a dropper is fixedly connected to the inner top wall of the paint applicator.

[0008] Preferably, a collecting plate is fixedly connected to the lower surface of the main board, and a winding roller is fixedly connected to the upper surface of the main board.

[0009] Preferably, a support frame is fixedly connected to the upper surface of the motherboard, and a dryer is slidably connected to the inner wall of the support frame.

[0010] Preferably, the outer wall of the dryer is provided with a groove, and a sliding rod is slidably connected inside the support frame.

[0011] Preferably, a rotating plate is fixedly connected to the outer wall of the sliding rod, and the outer wall of the rotating plate is slidably connected to the inside of the support frame.

[0012] Preferably, the outer wall of the rotating plate is rotatably connected to the inner wall of the groove, the outer wall of the sliding rod is fixedly connected to the limiting disk, and the outer wall of the limiting disk is slidably connected to the inside of the support frame.

[0013] Preferably, one end of a spring is fixedly connected to the outer wall of the limiting plate, and the other end of the spring is fixedly connected to the inside of the support frame.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the mutual cooperation between the main board, bracket, motor, gear, threaded rod and scraper achieves the effect of precise adjustment of scraper height, which helps to ensure accurate coating thickness, meet flame retardant performance standards, ensure consistency in mass production, avoid batch differences, reduce paint waste and scrap rate, reduce costs, and achieve the effect of ensuring product quality.

[0015] 2. In this utility model, the mutual cooperation between the support frame, the dryer, the sliding rod and the rotating plate achieves the effect of quick replacement and fixation of the dryer, which helps to significantly reduce downtime for changing models. The appropriate dryer can be flexibly replaced according to the curing requirements of different coatings, thereby improving the utilization rate of the equipment. Attached Figure Description

The motor 4 drives the gear 5 to rotate, and the gear 6 converts the vertical rotation of the gear 5 into the horizontal rotation of the threaded rod 7. The bracket 2 supports the rotation of the gear 6. The outer wall of the threaded rod 7 is threadedly connected to the scraper 8. The rotation drives the scraper 8 to slide up and down along the fixed rod 9 to adjust the height of the scraper 8. The scraper 8 is used to apply a flame-retardant coating to the non-woven fabric. The coating thickness is controlled by adjusting the height. The fixed rod 9 supports the scraper 8 to ensure its stability during lifting and lowering.

[0020] Reference Figure 1 The spraying assembly includes a paint applicator 10, the lower surface of which is fixedly connected to the upper surface of the main board 1, and a dropper 11 is fixedly connected to the inner top wall of the paint applicator 10. Specifically, the paint applicator 10 delivers raw materials into the dropper 11, which is used to apply the paint from the paint applicator 10 onto the non-woven fabric, thus achieving the spraying function. Example

[0021] Reference Figure 1 , Figure 4 and Figure 5 A collecting plate 12 is fixedly connected to the lower surface of the main board 1, and a winding roller 13 is fixedly connected to the upper surface of the main board 1. A support frame 14 is fixedly connected to the upper surface of the main board 1, and a dryer 15 is slidably connected to the inner wall of the support frame 14. A groove 16 is provided on the outer wall of the dryer 15, and a sliding rod 17 is slidably connected to the inside of the support frame 14. A rotating plate 18 is fixedly connected to the outer wall of the sliding rod 17, and the outer wall of the rotating plate 18 is slidably connected to the inside of the support frame 14. The outer wall of the rotating plate 18 is rotatably connected to the inner wall of the groove 16. A limiting plate 19 is fixedly connected to the outer wall of the sliding rod 17, and the outer wall of the limiting plate 19 is slidably connected to the inside of the support frame 14. One end of a spring 20 is fixedly connected to the outer wall of the limiting plate 19, and the other end of the spring 20 is fixedly connected to the inside of the support frame 14. Specifically, the collection plate 12 is used to collect excess paint dripping during spraying or scraping, facilitating recycling and equipment cleaning. Two take-up rollers 13 are installed on the upper surface of the main plate 1. The left take-up roller 13 receives the non-woven fabric, and the right take-up roller 13 winds up the coated non-woven fabric, achieving automated material collection. The support frame 14 supports the sliding mechanism of the dryer 15, which is used to dry the coated non-woven fabric, curing the flame-retardant coating and ensuring its effectiveness. The support frame 14 also supports the sliding rod 17. The inner wall of the groove 16 is circular, which supports the rotation of the rotating plate 18. After the rotating plate 18 rotates, it will fix the dryer 15. The movement of the sliding rod 17 can fix or loosen the dryer 15. The limiting plate 19 is used to limit the sliding range of the sliding rod 17 and provide a force point for the spring 20. The spring 20 provides a reset force to the sliding rod 17. When the rotating plate 18 rotates to a certain angle on the inner wall of the groove 16, it will be pulled out by the spring force of the spring 20 and loosened.

[0022] Working principle: When the device is needed, the non-woven fabric is placed on the outer wall of the left take-up roller 13, and pulled through the inside of the coating machine 10 and the dryer 15 to connect with the right take-up roller 13. The coating machine 10 is started to spray the flame-retardant layer onto the non-woven fabric through the drip tube 11. The motor 4 is started to drive the gear 5 at the output end to rotate. When the gear 5 rotates, the gear 6 connected by the tooth end meshes with the threaded rod 7 to rotate synchronously. When the threaded rod 7 rotates, the height of the scraper 8 is adjusted to scrape the flame-retardant layer on the surface of the non-woven fabric. This achieves precise adjustment of the height of the scraper 8, ensuring accurate coating thickness, meeting flame-retardant performance standards, ensuring consistency in batch production, avoiding batch differences, reducing paint waste and scrap rate, reducing costs, and achieving the effect of ensuring product quality. The scraped non-woven fabric will enter the interior of the support frame 14. The dryer 15 will be started to dry the coated non-woven fabric. When the dryer 15 needs to be replaced, the sliding rod 17 will be rotated to drive the rotating plate 18 to rotate synchronously on the inner wall of the groove 16. After rotating to a certain angle, the spring force of the spring 20 will push the limiting plate 19, causing the rotating plate 18 to disengage from the inner wall of the groove 16 through the sliding rod 17 when the limiting plate 19 moves. The fixing will be loosened, and the dryer 15 will be pulled to slide on the inner wall of the support frame 14 for replacement. Pressing the sliding rod 17 will drive the rotating plate 18 into the inner wall of the groove 16 after replacement. Twisting the sliding rod 17 will drive the rotating plate 18 to rotate synchronously on the inner wall of the groove 16, achieving the effect of quick replacement and fixing of the dryer 15. This can greatly reduce downtime for changing types. The appropriate dryer 15 can be flexibly replaced according to the curing requirements of different coatings, thereby improving the utilization rate of the equipment. In actual use, this device can not only achieve precise adjustment of the height of the scraper 8 to ensure accurate coating thickness, ensure consistency in batch production, avoid batch differences, reduce paint waste and scrap rate, reduce costs, and ensure product quality, but also achieve the effect of quick replacement and fixing of the dryer 15, which can greatly reduce downtime for changeover and flexibly replace the appropriate dryer 15, thereby improving equipment utilization.
