Description

Technical Field

[0001] This disclosure relates to the field of automotive seat manufacturing technology, and in particular to a seat leather heat-applying machine and an automotive seat manufacturing system. Background Technology

[0002] Throughout the entire automotive seat production process, the design of the seat leather needs to ensure seat performance and comfort. Typically, seat leather consists of a leather layer, an adhesive layer, and a sponge layer, and is manufactured using a heat-bonding machine to form a complete body.

[0003] However, during the manufacturing of seat leather, one side of the leather layer faces the heat-bonding conveyor. Since heat bonding typically requires temperatures of 120±5℃, there is a possibility that one side of the leather layer may adhere to the heat-bonding conveyor, thereby compromising the integrity of the seat leather. This results in inconsistent product quality during subsequent car seat production and also contaminates the heat-bonding conveyor, increasing cleaning and maintenance costs. Furthermore, to ensure product quality and production efficiency, frequent product inspections and conveyor belt cleaning are required, which not only increases labor costs but may also affect the continuity and stability of the production line.

[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0030] Please see Figures 1 to 5 This invention relates to a seat leather heat-applying machine 10, which includes a heat-applying conveyor 100, a heat-applying box 200, a heat-pressing mechanism 300, a main control unit 400, and a seat leather assembly 500. The heat-applying conveyor 100 has a placement area and a heat-applying area connected together. The heat-applying box 200 is disposed on the heat-applying conveyor 100 and has a heat-applying cavity 201 and a conveying port 202, which are connected. The heat-applying area is located inside the heat-applying cavity 201. The heat-pressing mechanism 300 is connected to the heat-applying box 200 and is located inside the heat-applying cavity 201. The heat-pressing mechanism 300 is aligned with the heat-applying area. The following configuration should be provided: A main control unit 400 is mounted on the heat-applying box 200. The heat-applying control terminal of the main control unit 400 is electrically connected to the heat-pressing mechanism 300, and the transmission control terminal of the main control unit 400 is electrically connected to the controlled terminal of the heat-applying conveyor 100. The seat leather assembly 500 includes release paper 510, seat cover 520, hot melt adhesive 530, and seat foam 540. The release paper 510 is located in the placement area, the seat cover 520 is placed on the release paper 510, the seat foam 540 is placed on the seat cover 520, and the hot melt adhesive 530 is placed on one side of the seat foam 540, with the hot melt adhesive 530 facing the seat cover 520. The main control unit 400 is used to control whether the heat-pressing mechanism 300 operates and whether the conveyor belt 120 in the heat-applying conveyor 100 moves.

[0031] In this embodiment, before producing seat leather, the seat leather heat-bonding machine 10 first places release paper 510 in the placement area of ​​the heat-bonding conveyor table 100, and then places the seat cover 520 and seat foam 540 in sequence. Upon completion of placement, the seat cover 520 and seat foam 540 are heat-bonded. The release paper 510 prevents the seat cover 520 from sticking to the heat-bonding conveyor table 100 during the heat-bonding process, ensuring the integrity of the seat leather and preventing contamination of the heat-bonding conveyor table 100 due to adhesion. This eliminates the need for frequent equipment cleaning during seat leather production, thereby improving production efficiency. Furthermore, the release paper 510 separates the seat cover 520 from the conveyor belt 120 of the heat-bonding conveyor table 100, preventing direct contact and thus preventing structural damage to the seat leather caused by heat bonding at high temperatures.

[0032] In one embodiment, the area of ​​the release paper 510 is greater than or equal to the area of ​​the seat cover 520, ensuring that when the operator places the seat cover 520, no part of its structure directly contacts the heat-bonding conveyor table 100. In other words, the release paper 510 separates the seat cover 520 from the heat-bonding conveyor table 100, preventing adhesion between them during the heat-bonding operation. In a preferred embodiment, the area of ​​the release paper 510 is larger than the area of ​​the seat cover 520, further ensuring that no part of the seat cover 520 directly contacts the heat-bonding conveyor table 100, and also facilitating the removal of the release paper 510 during subsequent seat leather fabrication.

[0033] In one embodiment, the coverage area of ​​the hot melt adhesive 530 is equal to the cross-sectional area of ​​the seat foam 540, so that when the seat foam 540 is heat-bonded to the seat cover 520, the contact surfaces of the seat foam 540 and the seat cover 520 are all bonded by the hot melt adhesive 530. When the seat leather is made, there will be no local voids, thus ensuring the quality of the seat leather.

[0034] In one embodiment, the release paper 510 is a rectangular release paper 510. It can be understood that when the release paper 510 is rectangular, it can be adapted to the production of different shapes of seat leather materials, such as seat back leather materials, seat bottom leather materials, etc., and it is also convenient to tear the release paper 510 during subsequent manufacturing to ensure the overall structure of the seat leather material.

[0035] In one embodiment, the thickness of the seat foam 540 is 9mm-12mm. In this embodiment, the thickness of the seat foam 540 is 10mm.

[0036] In one embodiment, the thickness of the seat cover 520 is 1mm-2mm. In this embodiment, the thickness of the seat cover 520 is 1mm.

[0037] like Figure 1 and Figure 4 As shown, in one embodiment, the heat transfer table 100 includes a support frame 110, a conveyor belt 120, a transfer motor 130, and at least two transfer rollers 140. The support frame 110 has at least two mounting channels 1101, and each transfer roller 140 is rotatably disposed in one mounting channel 1101. The transfer motor 130 is disposed on the support frame 110, and the drive end of the transfer motor 130 is connected to the axis of at least one transfer roller 140. The conveyor belt 120 is wrapped around the at least two transfer rollers 140 so that the conveyor belt 120 slides on the support frame 110. It is understood that when the start button is pressed on the main control unit 400, the conveyor motor 130 operates, driving at least one conveyor roller 140 to rotate, thereby driving the conveyor belt 120 to perform a transmission action. After the release paper 510, seat cover 520, and seat foam 540 are placed in sequence, the conveyor belt 120 carries the above materials to the interior of the heat-bonding box 200 for heat-bonding to produce seat leather. In this embodiment, the heat-bonding box 200 is set on the support frame 110, and the heat-bonding box 200 partially covers the conveyor belt 120, with the release paper 510 placed on the conveyor belt 120. Furthermore, both the placement area and the heat-bonding area are located on the conveyor belt 120. When placing materials, the raw materials for the seat leather are placed on the conveyor belt 120 and are all located within the placement area. After placement, the conveyor motor 130 drives the conveyor roller 140 to rotate, which in turn drives the conveyor belt 120 to work. Thus, these materials are transferred from the placement area to the heat bonding area, which is located inside the heat bonding box 200. Subsequently, the heat pressing mechanism 300 performs a heat bonding operation on the material to form the seat leather. When the heat bonding is completed, the conveyor belt 120 reverses and drives the heat-bonded material from the heat bonding area to the placement area. Then, the operator tears off the release paper 510 to complete the production of the seat leather.

[0038] In another embodiment, such as Figure 2 As shown, the transmission motor 130 is located on the side of the support frame 110, so that the horizontal plane of the support frame 110 is not too abrupt, making it convenient to place the release paper 510, seat cover 520 and seat foam 540 in sequence in the placement area.

[0039] In another embodiment, at least one installation channel 1101 is located inside the heat pack 200, that is, at least one conveyor roller 140 is located inside the heat pack 200. Specifically, the conveyor roller 140 located outside the heat pack 200 corresponds to the conveyor motor 130 and serves as the driving roller, while the conveyor roller 130 located inside the heat pack 200 serves as the driven roller. When the operator operates the main control unit 400 to start the transmission switch, the conveyor motor 130 starts and drives the conveyor roller 140 located outside the heat pack 200 to rotate, thereby driving the conveyor roller 130 located inside the heat pack 200 to rotate under the action of the conveyor belt 120.

[0040] This disclosure also provides an automotive seat manufacturing system, including the seat leather heat-applying machine 10 of any of the above embodiments.

[0041] Compared with the prior art, this disclosure has at least the following advantages:

[0042] The aforementioned seat leather heat-bonding machine 10 first places a release paper 510 in the placement area of ​​the heat-bonding conveyor table 100 before producing seat leather. Then, the seat cover 520 and seat foam 540 are placed in sequence. When the placement is completed, the seat cover 520 and seat foam 540 are heat-bonded. The release paper 510 can prevent the seat cover 520 from sticking to the heat-bonding conveyor table 100 during the heat-bonding process, ensuring the integrity of the seat leather. It also prevents the heat-bonding conveyor table 100 from being contaminated due to the seat cover 520 sticking to the heat-bonding conveyor table 100. As a result, the equipment does not need to be cleaned frequently when producing seat leather, thereby improving production efficiency.

[0043] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure.
