Description

Technical Field

[0001] The present invention relates to the technical field of automobile interior trim processing, and in particular to a three-dimensional embossing molding device and method for automobile interior trim felt. Background Art

[0002] The three-dimensional embossing process of automotive interior felt is a key link in improving the texture and functionality of interior decoration. In the existing technology, the embossing forming device mostly relies on the cooperation of the embossing roller and the bottom roller of the fixed structure to complete the processing, but there are many technical pain points in actual production. First, the embossing roller and the bottom roller of the traditional device are mostly fixedly installed. When it is necessary to inspect, maintain or replace the rollers of different sizes to adapt to the diverse pattern requirements, a large number of connectors need to be disassembled. The operation is cumbersome and time-consuming, which seriously affects production efficiency. Secondly, the pressure control accuracy during the embossing process is insufficient, and the interior felt fibers are often damaged or the embossing depth is uneven due to excessive downward pressure, or the pattern is blurred due to insufficient pressure, making it difficult to ensure product consistency. Furthermore, the structural design of the existing device lacks flexibility, and the layout of the embossing component and the cooling component is fixed. During inspection and maintenance, multiple components need to be operated separately, which further increases the complexity of the operation.

[0003] These problems not only restrict the improvement of production efficiency, but also make it difficult to meet the demand for personalized and high-precision embossing of automotive interiors. Therefore, there is an urgent need for an embossing forming device and method that can achieve convenient maintenance, precise pressure control, efficient cooling and adapt to a variety of roller sizes.

[0018] The present invention also provides a method for using a three-dimensional embossing molding device for automobile interior felt, comprising the following steps:

[0019] S1: First, the automotive interior felt to be processed is introduced from the strip opening on the left, and after passing between the three-dimensional embossing roller and the soft bottom roller, it passes between the two hollow plates and is led out from the strip opening on the right. During this process, the two upper support seats are controlled by the electric cylinder 2 to drive the three-dimensional embossing roller to move downward synchronously. At the same time, with the cooperation of multiple pressure sensors, the embossing force of the three-dimensional embossing roller can be monitored. As the embossing process progresses and the automotive interior felt continues to move right, it can be continuously embossed. At the same time, the cooling and heating fans are started. The cooling and heating fans can quickly cool the automotive interior felt that has been embossed after passing between the two hollow plates through the cooperation of the conveying pipes 1 and 2 and the two hollow plates;

[0021] S3: When it is necessary to disassemble and assemble the three-dimensional embossing roller and the soft bottom roller, the two-way screw is controlled to rotate by adjusting the motor so that the two upper support seats move away from each other, thereby facilitating the rapid disassembly of the three-dimensional embossing roller. At the same time, under the action of the guide plate, the two lower support seats can be controlled to move synchronously with the corresponding upper support seats, so that the core shaft of the soft bottom roller can be separated from the two lower support seats, thereby facilitating the rapid disassembly of the soft bottom roller. At the same time, since the spacing between the two upper support seats is adjustable, the two lower support seats will also move synchronously with the corresponding upper support seats, so that the device can not only realize the rapid disassembly and replacement of the three-dimensional embossing roller and the soft bottom roller, but also can well adapt to the installation of three-dimensional embossing rollers and soft bottom rollers of different sizes, thereby effectively improving the applicability of the device.

[0022] Compared with the prior art, the present invention provides a three-dimensional embossing forming device and method for automobile interior felt, which has the following beneficial effects:

[0023] (1) The turning assembly is provided to facilitate the operation of the three-dimensional embossing roller and the soft bottom roller during the inspection and maintenance. At the same time, the fixing frame connected to the mounting frame is provided to drive the hollow plate to turn upward to the top of the box body when the cover plate and the mounting frame are turned over.

[0024] (2) By setting the spacing adjustment component and the linkage component, the convenience of disassembling and replacing the three-dimensional embossing roller and the soft bottom roller can be effectively improved. At the same time, it can also adapt to three-dimensional embossing rollers and soft bottom rollers of different sizes according to actual use needs.

[0025] (3) By setting up the cooling and heating fans, the conveying pipe 1, the conveying pipe 2 and the hollow plate, the embossed automobile interior felt can be quickly cooled.

[0026] (4) Through the cooperation of the lifting and adjusting components and multiple pressure sensors, the downward pressure of the three-dimensional embossing roller during embossing can be monitored in real time to avoid excessive downward pressure or inadequate embossing.

[0027] To sum up, the three-dimensional embossing forming device and method of automobile interior felt of the present invention are not only simple and convenient to operate, but also convenient for quick disassembly, replacement and maintenance of the three-dimensional embossing roller and the soft bottom roller.

The ends of the two sliding pins that are close to each other are fixedly connected to the corresponding lower support seats 41 respectively.

[0050] This embodiment also provides a method for using a three-dimensional embossing device for automotive interior felt, comprising the following steps:

[0051] S1: First, the automobile interior decoration felt to be processed is introduced from the strip opening on the left, and after passing between the three-dimensional embossing roller 3 and the soft bottom roller 4, it passes between the two hollow plates 5 and is led out from the strip opening on the right. During this process, the two upper support seats 31 are controlled by the electric cylinder 2 32 to drive the three-dimensional embossing roller 3 to move downward synchronously. At the same time, with the cooperation of multiple pressure sensors 324, the embossing force of the three-dimensional embossing roller 3 can be monitored. As the embossing process progresses and the automobile interior decoration felt continues to move right, it can be continuously embossed. At the same time, the heating and cooling fan 51 is started. The heating and cooling fan 51 can quickly cool the automobile interior decoration felt that has been embossed between the two hollow plates 5 through the cooperation of the conveying pipe 1 52 and the conveying pipe 2 53 and the two hollow plates 5;

[0052] S2: When the three-dimensional embossing roller 3 needs to be inspected or maintained, the cover plate 2 is turned counterclockwise around the support shaft 21 by the electric cylinder 1 201, so that the mounting frame 22 can be turned over to the top of the box body 1, and then the inspection or maintenance operation can be carried out, which greatly improves the convenience of maintenance and inspection.

[0053] S3: When it is necessary to disassemble and assemble the three-dimensional embossing roller 3 and the soft bottom roller 4, the two-way screw rod 312 is controlled to rotate by adjusting the motor 313, so that the two upper support seats 31 move in the direction away from each other, thereby facilitating the rapid disassembly of the three-dimensional embossing roller 3. At the same time, under the action of the guide plate 42, the two lower support seats 41 can be controlled to follow the corresponding upper support seats 31 for synchronous movement, so that the core shaft of the soft bottom roller 4 can be disengaged from the two lower support seats 41, thereby facilitating the rapid disassembly of the soft bottom roller 4. At the same time, since the spacing between the two upper support seats 31 is adjustable, the two lower support seats 41 will also move synchronously with the corresponding upper support seats 31, so that the device can not only realize the rapid disassembly and replacement of the three-dimensional embossing roller 3 and the soft bottom roller 4, but also can well adapt to the installation of three-dimensional embossing rollers 3 and soft bottom rollers 4 of different sizes, thereby effectively improving the applicability of the device.
