Description

Technical Field

[0001] This utility model relates to the field of flame retardant treatment technology for automotive interior fabrics, and in particular to a flame retardant treatment device for automotive interior fabrics. Background Technology

[0002] With the booming development of the automotive industry and the increasing demands of consumers for automotive safety and comfort, the quality and performance of automotive interior fabrics have received more and more attention. The flame retardant properties of interior fabrics are directly related to the life safety of occupants in emergency situations such as fires. Therefore, it is particularly important to carry out effective flame retardant treatment on automotive interior fabrics.

[0003] Currently, there are various methods for flame retardant treatment of automotive interior fabrics. Some traditional treatment devices have difficulty ensuring uniformity of spraying when applying flame retardant. Due to the different sizes and shapes of interior fabrics, traditional fixed spraying equipment cannot be flexibly adjusted according to the width and length of the fabric, resulting in some areas being sprayed with too much flame retardant while others are sprayed with too little. This not only wastes flame retardant but also fails to achieve the ideal flame retardant effect.

[0004] To address the problems existing in the above-mentioned technologies and improve the quality and efficiency of flame-retardant treatment of automotive interior fabrics, it is of great practical significance to develop a new type of flame-retardant treatment device for automotive interior fabrics.

The T-shaped rod is movably connected to the inner wall of the through hole opened at the top of the nozzle, and the connecting piece is fixed between the inner walls on both sides of the limiting frame. The connecting piece and the bottom of the T-shaped rod are fixedly connected. The spring is sleeved on the outer wall of the T-shaped rod and both ends of the spring are respectively fixed to the inner wall at the top of the T-shaped rod and the outer wall at the top of the nozzle.

[0011] As a further embodiment of this utility model: a drive motor is fixed to one outer wall of the limiting frame, and a bracket is fixed to the output end of the drive motor via a pin. Rollers are movably connected to the inner walls on both sides of the bracket, and an arc-shaped block that works in conjunction with the rollers is fixed to the top outer wall of the nozzle.

[0012] As a further embodiment of this utility model: the flame retardant delivery mechanism includes a hose, a support plate and a delivery pump. The support plate is fixed to the outer wall of one side of the cabinet, and the delivery pump is fixed to the top of the support plate.

The elastic element, together with the drive motor, bracket, roller and arc block, allows the spray nozzle and spray pipe to move up and down a certain distance along the inner wall of the limiting frame. According to the different lengths of the interior fabric, more uniform spraying is achieved, which effectively ensures the spraying quality and ensures that the flame retardant can fully and evenly cover the surface of the interior fabric, thereby improving the flame retardant treatment effect.

[0019] 2. By using a drive motor to rotate the clamping assembly, the interior fabric can be easily rotated to the appropriate position, enabling spraying on both sides without the need for manual flipping of the fabric. This greatly improves operational efficiency and reduces the time and labor intensity of manual operation.

[0020] 3. The telescopic protective sleeve installed between the slider and the two pads can effectively protect the threaded rod and guide rod, preventing flame retardant from adhering to their surface during the spraying process, thus reducing their service life and ensuring the stable operation of the slide assembly. The sealing strip bonded to the outer wall of one side of the cabinet improves the sealing between the cabinet door and the cabinet body after the door is closed. Closing the cabinet door during the spraying process can effectively prevent flame retardant from overflowing and reduce pollution to the surrounding environment.

[0021] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] A flame-retardant treatment device for automotive interior fabrics, such as Figures 1 to 6 As shown, the cabinet includes a cabinet body 1. A slide rail assembly is installed on one inner wall of the cabinet body 1, and a slider 13 is slidably connected to the slide rail assembly. A limit frame 12 is fixed to one outer wall of the slider 13 by bolts. An L-shaped cover plate 20 is fixed to one side of the limit frame 12. Elastic elements are installed on the inner walls of both sides of the limit frame 12, and a spray pipe 28 is installed on the elastic elements. Multiple sets of nozzles 27 are fixed to one outer wall of the spray pipe 28, and a flame retardant delivery mechanism is connected to the other outer wall of the spray pipe 28. A drive motor 5 is fixed to the top outer wall of the cabinet body 1 by bolts, and a clamping assembly for fixing the interior fabric is installed at the output end of the drive motor 5.

[0031] When flame retardant treatment is required on interior fabrics, the fabrics to be treated are first vertically unfolded and clamped and fixed using a clamping assembly. The clamping assembly is then rotated using a drive motor 5, causing one side of the vertically unfolded fabric to rotate to a position parallel to the limiting frame 12. The flame retardant is then delivered to the nozzle 28 using a flame retardant delivery mechanism. Finally, the flame retardant is sprayed onto the surface of the interior fabric using a nozzle 27. The position of the nozzle 27 in the lateral direction is adjusted using a slide assembly, allowing the nozzle 27 to spray the fabric evenly according to its width during lateral movement. The nozzle 27 and nozzle 28 are equipped with elastic elements, allowing them to move up and down a certain distance along the inner wall of the limiting frame 12, thereby ensuring that multiple nozzles 27 spray the interior fabric surface more evenly according to the different lengths of the fabric.

[0032] After one side of the interior fabric is coated, if the other side of the interior fabric needs to be coated, the drive motor 5 drives the clamping assembly to rotate so that the other side of the interior fabric faces the spray nozzle 27, so that the spray nozzle 27 can be used to coat the other side of the interior fabric.

[0033] The slide assembly includes a guide rod 18 and a pad 21. Both pads 21 are fixed to the inner wall of one side of the cabinet 1 by bolts, and the guide rod 18 is fixed between the two pads 21 by screws. The slider 13 and the guide rod 18 are slidably connected. A drive motor 14 is fixed to the outer wall of one side of the pad 21 by bolts. A threaded rod 17 is rotatably connected between the two pads 21. The output end of the drive motor 14 and one end of the threaded rod 17 are connected by a coupling. The threaded rod 17 and the slider 13 are threadedly connected.

[0034] The drive motor 14 can drive the threaded rod 17 to rotate, causing the slider 13 to move laterally under the guidance of the guide rod 18, thereby adjusting the position of the nozzle 27 in the lateral direction. The outer shell of the drive motor 14 is treated with anti-corrosion and anti-rust treatment.

[0035] A telescopic protective sleeve 9 is installed between the slider 13 and the two pads 21;

[0036] The threaded rod 17 and guide rod 18 can be protected by the telescopic protective sleeve 9, which prevents flame retardant from adhering to their surfaces during the spraying process and reducing their service life.

[0037] The elastic element includes a spring 24, a T-shaped rod 25, and a connecting piece 26. The T-shaped rod 25 is slidably connected to the inner wall of the through hole at the top of the nozzle 28, and the connecting piece 26 is fixed between the inner walls of the two sides of the limiting frame 12 by screws. The connecting piece 26 and the bottom of the T-shaped rod 25 are fixedly connected. The spring 24 is sleeved on the outer wall of the T-shaped rod 25, and the two ends of the spring 24 are respectively fixed to the inner wall at the top of the T-shaped rod 25 and the outer wall at the top of the nozzle 28.

[0038] The outer wall of one side of the limiting frame 12 is fixed with a drive motor 29 by bolts, and the output end of the drive motor 29 is fixed with a bracket 19 by pins. Rollers 22 are rotatably connected to the inner walls on both sides of the bracket 19, and an arc-shaped block 23 that works with the roller 22 is fixed to the top outer wall of the nozzle 28 by screws.

[0039] When the drive motor 29 drives the bracket 19 and roller 22 to rotate, the roller 22 squeezes the arc surface of the arc block 23 when it rotates to the arc block 23. The spring 24 is compressed, causing the nozzle 28 and the nozzle 27 to move down a certain distance along the limit frame 12. When the roller 22 is disengaged from the arc block 23, the spring force of the spring 24 causes the nozzle 28 and the nozzle 27 to move up and reset. In this way, the nozzle 27 can spray the flame retardant more evenly on the surface of the interior fabric during the up and down movement. The outer shell of the drive motor 29 is also treated with anti-corrosion and anti-rust treatment.

[0040] The flame retardant delivery mechanism includes a hose 6, a support plate 7, and a delivery pump 8. The support plate 7 is fixed to the outer wall of one side of the cabinet 1 by bolts, and the delivery pump 8 is fixed to the top of the support plate 7. The hose 6 is connected between the spray pipe 28 and the delivery pump 8.

[0041] During spraying, the end of the delivery pump 8 away from the hose 6 is connected to the paint tank (not shown). The flame retardant is pumped by the delivery pump 8 and then enters the spray pipe 28 through the hose 6, and finally sprayed onto the surface of the interior fabric through the nozzle 27.

[0042] The clamping assembly includes a mounting plate 10, a spring clip 15, and a rotating rod 16. The rotating rod 16 is connected to the output end of the drive motor 5 via a coupling, and the mounting plate 10 is welded to the side wall of the rotating rod 16, and the spring clip 15 is fixed to the side wall of the mounting plate 10.

[0043] When fixing the interior fabric, use spring clips 15 to hold the upper and lower sides of the interior fabric respectively. The spring clips 15 can be installed and used with commercially available specifications.

[0044] Both sides of the cabinet 1 are hinged with cabinet doors 4, and observation windows 3 are installed on the cabinet doors 4;

[0045] During the spraying process, the cabinet door 4 is closed to prevent the flame retardant from overflowing. The observation window 3 allows for easy observation of the spraying process inside the cabinet 1.

[0046] A sealing strip 11 is adhered to one side of the outer wall of the cabinet 1;

[0047] The sealing strip 11 can improve the sealing performance between the cabinet door 4 and the cabinet body 1 after the door is closed.

[0048] A controller 2 is installed on one outer wall of the cabinet 1;

[0049] The controller 2 can control the drive motor 5 to drive the clamping assembly to rotate through a preset program or operation command, so as to realize the switching of spraying the front and back sides of the interior fabric. At the same time, it controls the drive motor 14 to drive the threaded rod 17 to rotate, so that the slider 13 moves laterally on the guide rod 18, and adjusts the lateral position of the nozzle 27. It controls the drive motor 29 to drive the bracket 19 and roller 22 to rotate, and with the help of the elastic element, the nozzle 27 moves up and down to ensure uniform spraying. It can also control the start and stop and the operating parameters of the delivery pump 8 to pump the flame retardant from the paint tank to the spray pipe 28 and the nozzle 27 to complete the flame retardant treatment of the automotive interior fabric.

[0050] Working principle: First, the interior fabric to be processed is vertically unfolded. The upper and lower sides of the fabric are clamped and fixed with spring clips 15. Then, the clamping assembly is rotated using a drive motor 5, causing one side of the vertically unfolded fabric to rotate to a position parallel to the limiting frame 12. Next, flame retardant is sprayed. The flame retardant is pumped by a delivery pump 8, entering the spray nozzle 28 through a hose 6, and then sprayed onto the surface of the interior fabric through the nozzle 27. During the spraying process, the position of the nozzle 27 in the lateral direction is adjusted using a slide assembly, ensuring even spraying according to the width of the fabric. The threaded rod 17 is rotated by a drive motor 14, causing the slider 13 to move laterally under the guidance of the guide rod 18, thereby adjusting the lateral position of the nozzle 27. When the bracket 19 and roller 22 are rotated by a drive motor 29, the roller 22, when rotating to the arc block 23,... The curved surface is compressed, and the spring 24 is compressed, causing the nozzle 28 and the nozzle 27 to move down a certain distance along the limiting frame 12. When the roller 22 is disengaged from the curved block 23, the spring 24 rebounds, causing the nozzle 28 and the nozzle 27 to move up and reset. In this way, the nozzle 27 sprays the flame retardant more evenly on the surface of the interior fabric during the up and down movement. After one side of the interior fabric is sprayed, if the other side of the interior fabric needs to be sprayed, the drive motor 5 drives the clamping assembly to rotate again, so that the other side of the interior fabric faces the nozzle 27, and the nozzle 27 sprays the other side of the interior fabric. During the spraying process, the cabinet doors 4 hinged on both sides of the cabinet 1 are closed to prevent the flame retardant from overflowing during the spraying process. The observation window 3 installed on the cabinet door 4 facilitates the observation of the spraying process inside the cabinet 1. The sealing strip 11 bonded to the outer wall of one side of the cabinet 1 can improve the sealing between the cabinet door 4 and the cabinet 1 after it is closed.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
