Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive interior processing technology, and more specifically, it relates to an automotive interior curing device. Background Technology
[0002] The processing of automotive interior leather is a key step in enhancing the sense of luxury, comfort, and durability in automobile manufacturing. Typically, the interior processing involves wrapping natural or artificial leather, which is then cut and vacuum-adsorbed onto the surface of the interior parts using an adhesive method. Heating and curing are then used to improve the bonding efficiency. However, after the interior parts are processed by the vacuum activation adsorption machine, they are piled up in a curing chamber for heating and curing, resulting in uneven heating. If they are not piled up and heated and cured separately, the efficiency will be low.
[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an automotive interior curing device in order to achieve a more practical purpose. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides an automotive interior curing device to solve the issues of uneven heating when a large number of interior parts are piled up in the curing chamber for heating and curing, and low efficiency when they are heated and cured separately without being piled up.
[0005] The purpose and effect of this utility model's automotive interior curing device are achieved through the following specific technical means:
[0006] An automotive interior curing device includes a curing chamber, a hot air device, and a transmission device. An inlet belt and an outlet belt are respectively arranged on one side of the curing chamber. The hot air device is located at the top of the curing chamber. A base is installed inside the curing chamber, and a holding ring is rotatably mounted on the base. The holding ring corresponds to the ends of the inlet belt and the outlet belt. Multiple circumferentially distributed trays are arranged on the holding ring. The bottom of each tray is rotatably connected to the holding ring via a rotating column. A toothed ring is arranged on the periphery of the base, and a gear meshing with the toothed ring is located at the bottom of the rotating column. The transmission device drives the holding ring to rotate, causing the trays to rotate in a planetary gear structure.
[0007] Furthermore, a groove is provided on the base along its circumference, the inner ring of the holding ring extends on the base, and a slider is provided at the bottom of the inner ring of the holding ring and locked in the groove. A central cover is provided on the base, the center of the central cover is connected to the base, and its end is fastened to the holding ring.
[0008] Furthermore, a baffle is provided on the central cover, the baffle is inclined and faces the shipping conveyor, and the baffle is located above the pallet.
[0009] Furthermore, the transmission device includes a motor mounted on the base, a rack distributed along its inner ring above the end of the holding ring, and a bevel gear connected to the output shaft of the motor, the bevel gear meshing with the rack.
[0010] Furthermore, the end of the infeed belt is positioned above the pallet, and the end of the outfeed belt is positioned below the holding ring, and both the infeed belt and the outfeed belt are belt conveyor mechanisms.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] Interior trim parts that need to be cured are fed into the curing chamber via a feed conveyor belt. The interior trim parts fall from the feed conveyor belt end onto the tray of the holding ring. The interior trim parts then enter the curing chamber and are rotated and heated to cure until they reach the end of the discharge conveyor belt. As the holding ring rotates the interior trim parts, the tray can also rotate the interior trim parts, keeping them in dynamic curing and heating. This results in more uniform heating and allows for a continuous supply of interior trim parts, leading to higher heating efficiency. Attached Figure Description

[0021] Example:
[0022] As attached Figure 1 To be continued Figure 3 As shown:
[0023] This utility model provides an automotive interior curing device, including a curing chamber 1, a hot air device 12, and a transmission device. The hot air device 12 is located on the top of the curing chamber 1. An infeed belt 2 and an outfeed belt 3 are respectively arranged on one side of the curing chamber 1. Both the infeed belt 2 and the outfeed belt 3 are belt conveyor mechanisms. The infeed belt 2 continuously transports the wrapped interior parts into the curing chamber 1, where they are heated and cured by the hot air device 12. The outfeed belt 3 outputs the cured interior parts.
[0024] A base 4 is installed inside the curing chamber 1. A holding ring 6 is rotatably mounted on the base 4, corresponding to the ends of the infeed belt 2 and the outfeed belt 3. Multiple circumferentially distributed trays 7 are mounted on the holding ring 6. The end of the infeed belt 2 is positioned above the trays 7, and the end of the outfeed belt 3 is positioned below the holding ring 6. Interior trim pieces fed onto the infeed belt 2 can fall onto the trays 7, while interior trim pieces that have rotated one revolution on the holding ring 6 fall onto the outfeed belt 3 for output. Figure 1 and Figure 3 As shown, a baffle 8 is provided on the central cover 5. The baffle 8 is tilted and faces the delivery belt 3. The baffle 8 is located above the tray 7. After the interior parts follow the holding ring 6 to rotate once in the curing chamber 1, they come into contact with the tilted baffle 8 and are guided to fall onto the delivery belt 3.
[0025] In this embodiment, a rotating seat is provided on the center cover 5, and one end of the baffle 8 is hinged to the rotating seat. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring abuts against the baffle 8, and the other end abuts against the center cover 5, so that the baffle 8 can move. The interior parts are guided to the delivery belt 3 by the elastic force of the torsion spring, so as to avoid jamming during the conveying process.
[0026] The bottom of the tray 7 is rotatably connected to the holding ring 6 via the rotating column 10. The base 4 is provided with a toothed ring 9 around its perimeter, and the bottom of the rotating column 10 is provided with a gear 11 that meshes with the toothed ring 9. The transmission device drives the holding ring 6 to rotate, so that the tray 7 rotates in a planetary gear structure. During the process of the holding ring 6 driving the interior parts to rotate, the tray 7 can also drive the interior parts to rotate, so that they are in dynamic curing and heating, the heating is more uniform, and the interior parts can be continuously fed in, resulting in higher heating efficiency.
[0027] like Figure 2 As shown, the transmission device includes a motor 13 mounted on the base 4, a rack 602 distributed along the inner ring above the end of the holding ring 6, a bevel gear 14 connected to the output shaft of the motor 13, the bevel gear 14 meshing with the rack 602, the motor 13 being protected inside the central cover 5 from external contact, and the motor 13 driving the bevel gear 14, which in turn drives the rack 602 to rotate the holding ring 6, thus transporting the interior parts inside the curing chamber 1, while the gear ring 9 on the base 4 is stationary, and the bottom gear 11 of the tray 7, which moves with the holding ring 6, is driven to rotate by the gear ring 9.
[0028] The hot air device 12 provides temperature for the existing hot air blower, which will not be elaborated on further.
[0029] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
