Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a drying device for automotive plastic parts. Background Technology
[0002] Automotive plastic parts refer to various components made primarily of plastic used in automobile manufacturing. These parts play a vital role in automobiles, widely used in the body, interior, exterior, and functional components. Automotive plastic parts are an indispensable part of modern automobile manufacturing, encompassing exterior parts, interior parts, and functional accessories. They not only enhance the performance and aesthetics of automobiles but also offer significant advantages in lightweighting, corrosion resistance, and ease of processing. With advancements in materials science and manufacturing technology, automotive plastic parts will play an even more important role in the future.
[0003] Automotive plastic parts may absorb moisture from the air or retain volatile substances generated during the molding process. This moisture and volatile substances can cause problems in subsequent processing (such as painting and assembly). For example, if moisture remains on the surface of automotive plastic parts, problems such as blistering, peeling, or insufficient adhesion may easily occur during painting. Drying ensures the surface of automotive plastic parts is dry, improves the adhesion between the coating and the plastic, and thus enhances the aesthetics and durability of the final product. This necessitates the use of automotive plastic part drying equipment, as described below.
[0004] A search revealed a patent with publication number CN215002722U, which discloses a drying device for automotive plastic parts. The device includes an oven with a body. Several protrusions are arranged in a ring on the inner wall of the top of the oven. Several racks are rotatably connected inside the oven. Automotive plastic parts are hung on the racks, and multiple sets of plastic parts are heated simultaneously via these racks, improving drying efficiency. When the motor rotates, it drives a lower disk to rotate inside the oven. During rotation, the groove formed between every two outer teeth of the gear disc at the top of the shaft engages with the protrusions. When the front side of the rear outer tooth contacts the protrusion, the rotation of the lower disk causes the gear disc to rotate in the opposite direction, thus rotating and heating the parts hung on the racks. The heating rod is positioned at the geometric center of the multiple racks, allowing for simultaneous rotation and drying of multiple sets of parts. The device has a simple structure and improves drying efficiency.
[0005] However, the aforementioned automotive plastic parts drying device still has the following areas for improvement. For example, when hanging automotive plastic parts, since the storage rods are located inside the device and cannot be removed, multiple automotive plastic parts can only be hung directly or indirectly on the storage rods by opening the device's door panel. However, due to the limited operating space after the door panel is opened, it is difficult to conveniently and quickly hang multiple automotive plastic parts on all the storage rods. For instance, during the hanging process, it is necessary to continuously adjust the position and angle of multiple rotating shafts and multiple sets of storage rods to bring them close to the operating position after the door panel is opened before the automotive plastic parts can be hung on the storage rods. The same applies when removing the plastic parts, making the hanging and removal of automotive plastic parts time-consuming, laborious, and extremely inconvenient, reducing overall work efficiency. Therefore, its structure needs to be improved, and its practicality needs to be enhanced. Utility Model Content
[0006] This utility model discloses a drying device for automotive plastic parts. It features a detachable drying rack mechanism, allowing the top cover to be removed directly by lifting during operation. Then, by holding the handle, the movable shaft is pulled out of the rotating shaft seat until it separates from the seat. The movable shaft can then be removed from the main body of the device. The movable shaft, along with multiple base plates, can be stably placed on the ground or other flat surface, fully exposing multiple hanging rods and hooks. This significantly expands the operator's working space, allowing for quick and convenient hanging of multiple automotive plastic parts directly or indirectly onto the hooks. After hanging, the movable shaft can be lifted by the handle and inserted into the rotating shaft. The movable shaft is inserted into the slot of the seat, and the bottom plate and top plate are aligned and engaged with the limiting slot until the bottom end of the movable shaft abuts against the inner bottom surface of the insertion slot. This completes the installation of the movable shaft, allowing multiple automotive plastic parts to be quickly and easily placed into the interior of the device body. At this point, the top cover can be closed, and the drive motor and multiple heating tubes can be started. The drive motor drives the rotating shaft seat to rotate, thereby driving multiple hanging rods to rotate. With the help of multiple heating tubes, the automotive plastic parts can be effectively dried. The same process is repeated in reverse when removing the plastic parts. In summary, this method saves time and effort in hanging and removing plastic parts, and is highly efficient. Therefore, it solves the problems in the background technology.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0008] This utility model discloses a drying device for automotive plastic parts, including a base, on the top of which the main body of the device is fixedly mounted, and a top cover is movably attached to the top of the main body of the device. Multiple annular heating tubes are fixedly installed inside the main body of the device.
[0009] A detachable drying rack mechanism includes a drive motor, a rotating shaft seat, a movable shaft, and hanging rods. The drive motor is fixedly installed at the bottom of the main body of the device via an installation component. The bottom end of the rotating shaft seat movably passes through the bottom of the main body of the device and is rotatably connected to the main body of the device. The bottom end of the rotating shaft seat is connected to the output end of the drive motor. The top of the rotating shaft seat has an insertion slot extending deep into its interior. Multiple limiting slots communicating with the insertion slot are vertically and evenly spaced around the rotating shaft seat. The movable shaft matches and engages with the insertion slot. Multiple bottom plates and top plates are provided on the outside of the movable shaft. The bottom end of the bottom plate is flush with the bottom end of the movable shaft. The top plate is close to the top end of the rotating shaft seat. Both the bottom plate and the top plate match and engage with the limiting slots. Multiple hanging rods are provided. The bottom end of the hanging rod is rotatably connected to the top of the bottom plate. The top end of the hanging rod movably passes through the top plate and is rotatably connected to the top plate. Multiple hooks are provided around the hanging rod.
[0010] An auxiliary uniform drying mechanism is located on the inner wall of the main body of the device and at the top of the hanging rod.
[0011] Furthermore, two handles are fixedly connected to the top of the top cover, and an exhaust port is provided at the top of the top cover.
[0012] Furthermore, adjacent bottom plates are fixedly connected by an arc-shaped first connecting rod, and adjacent top plates are fixedly connected by an arc-shaped second connecting rod.
[0013] Furthermore, a lifting handle is fixedly connected to the top of the movable shaft, and the lifting handle is T-shaped.
[0014] Furthermore, the movable shaft, base plate, top plate, hanging rod, hook, and lifting handle are all made of aluminum alloy, and the lifting handle is fixedly connected to the movable shaft by welding.
[0015] Furthermore, two hot air blowers are fixedly installed on the top of the base, and the air outlet of the hot air blowers extends through the bottom of the main body of the device and into the interior of the main body of the device.
[0016] Furthermore, the auxiliary uniform drying mechanism includes a fixed toothed plate and a transmission gear. Multiple fixed toothed plates and transmission gears are provided. Multiple fixed toothed plates are fixedly installed in a ring array on the inner wall of the device body. The transmission gear is fixedly fitted on the outside of the hanging rod. The fixed toothed plates and transmission gears are located at the same plane height. The side of the fixed toothed plate away from the inner wall of the device body is provided with teeth that match the transmission gear.
[0017] The present invention has the following advantages over the prior art:
[0018] 1. This technical solution features a detachable drying rack mechanism. During operation, the top cover can be lifted directly, allowing the detachable drying rack mechanism to be removed and the main body of the device taken out. This allows the device to be placed stably on the ground or other flat surface, fully exposing the multiple hanging rods and hooks within the detachable drying rack mechanism. This significantly expands the operator's working space, enabling them to quickly and easily hang multiple automotive plastic parts directly or indirectly on the hooks. After hanging, the detachable drying rack mechanism can be reinstalled inside the main body of the device, allowing the automotive plastic parts to be quickly and easily placed inside. The top cover can then be closed, and the drive motor and multiple heating elements can be activated. The drive motor rotates the rotating shaft, causing the multiple hanging rods to rotate. Combined with the heating elements, this effectively dries the automotive plastic parts. The same process is repeated when removing the plastic parts. Overall, this method saves time and effort in hanging and removing plastic parts, resulting in high efficiency and significantly improving overall work efficiency.
[0019] 2. This technical solution incorporates an auxiliary uniform drying mechanism. During operation, the drive motor rotates the rotating shaft seat, which in turn rotates multiple hanging rods. This, in turn, drives the transmission gear in a circular motion. When the transmission gear meshes with the fixed toothed plate, the meshing between the fixed toothed plate and the transmission gear causes the transmission gear to rotate by a certain angle, which in turn causes the hanging rods to rotate by a certain angle. Therefore, multiple automotive plastic parts can be rotated by a certain angle, effectively improving the drying uniformity of the heating element on multiple automotive plastic parts and further enhancing the practicality of the device.

[0029] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:
[0031] Reference Figures 1-5 A drying device for automotive plastic parts includes a base 1, a device body 2 fixedly mounted on the top of the base 1, a top cover 3 movably mounted on the top of the device body 2, and multiple annular heating tubes 4 fixedly mounted inside the device body 2.
[0032] The detachable drying rack mechanism 5 includes a drive motor 501, a rotating shaft seat 502, a movable shaft 503, and a hanging rod 504. The drive motor 501 is fixedly installed at the bottom of the device body 2 via a mounting component. The bottom end of the rotating shaft seat 502 movably passes through the bottom of the device body 2 and is rotatably connected to the device body 2. The bottom end of the rotating shaft seat 502 is connected to the output end of the drive motor 501. The top of the rotating shaft seat 502 has an insertion groove 505 extending deep into its interior. Multiple limiting grooves 506, which communicate with the insertion groove 505, are vertically and equally spaced around the rotating shaft seat 502. The movable shaft 503 is matched with the insertion groove 505. The movable shaft 503 is equipped with multiple base plates 507 and top plates 508. The bottom end of the base plate 507 is flush with the bottom end of the movable shaft 503, and the top plate 508 is close to the top of the rotating shaft seat 502. Both the base plate 507 and the top plate 508 are matched and engaged with the limiting groove 506. Multiple hanging rods 504 are provided. The bottom end of the hanging rod 504 is rotatably connected to the top of the base plate 507, and the top end of the hanging rod 504 movably passes through the top plate 508 and is rotatably connected to the top plate 508. Multiple hooks 509 are provided around the hanging rod 504. An auxiliary uniform drying mechanism 6 is located on the inner wall of the main body 2 and at the top of the hanging rod 504.
[0033] Two handles 7 are fixedly connected to the top of the top cover 3, and an exhaust port 8 is provided at the top of the top cover 3; adjacent bottom plates 507 are fixedly connected by an arc-shaped first connecting rod 510, and adjacent top plates 508 are fixedly connected by an arc-shaped second connecting rod 511; a lifting handle 512 is fixedly connected to the top of the movable shaft 503, and the lifting handle 512 is T-shaped; the movable shaft 503, bottom plate 507, top plate 508, hanging rod 504, hook 509 and lifting handle 512 are all made of aluminum alloy, and the lifting handle 512 is fixedly connected to the movable shaft 503 by welding; two hot air blowers 9 are fixedly installed on the top of the base 1, and the air outlet of the hot air blower 9 extends through the bottom of the device body 2 and into the interior of the device body 2.
[0034] In the specific implementation process, during operation, the top cover 3 can be directly removed by lifting upwards. Then, by holding the lifting handle 512, the movable shaft 503 can be lifted and pulled out from the rotating shaft seat 502 until the movable shaft 503 separates from the rotating shaft seat 502. The movable shaft 503 can then be removed from the main body 2 of the device. The movable shaft 503, together with multiple base plates 507, can be stably placed on the ground or other flat surfaces, so that multiple hanging rods 504 and hooks 509 are fully exposed, greatly expanding the operator's operating space. This allows the operator to quickly and conveniently hang multiple automotive plastic parts directly or indirectly on multiple hooks 509. After hanging, the movable shaft 503 can be lifted by the lifting handle 512 and inserted into the rotating shaft seat. Insert the movable shaft 503 into the insertion slot 502, and align and engage the bottom plate 507 and top plate 508 with the limiting slot 506 until the bottom end of the movable shaft 503 abuts against the inner bottom surface of the insertion slot. This completes the installation of the movable shaft 503, allowing multiple automotive plastic parts to be quickly and easily placed into the interior of the main body 2 of the device. At this point, the top cover 3 can be closed, and the drive motor 501 and multiple heating tubes 4 can be started. The drive motor 501 drives the rotating shaft seat 502 to rotate, thereby driving multiple hanging rods 504 to rotate. With the help of multiple heating tubes 4, the automotive plastic parts can be effectively dried. The same principle applies when removing the plastic parts; simply repeat the above operation in reverse. In summary, this method saves time and effort and is highly efficient in hanging and removing plastic parts.
[0035] Among them, the handle 7 is to facilitate the user to disassemble and install the top cover 3, and the exhaust port 8 is to facilitate the discharge of water vapor evaporated due to high temperature;
[0036] Among them, the first connecting rod 510 can improve the overall stability of multiple base plates 507, and the second connecting rod 511 can improve the overall stability of multiple top plates 508.
[0037] The handle 512 is for the convenience of installing and removing the movable shaft 503;
[0038] Among them, the movable shaft 503, base plate 507, top plate 508, hanging rod 504, hook 509, and handle 512 are all made of aluminum alloy. This is to ensure that the movable shaft 503, base plate 507, top plate 508, hanging rod 504, hook 509, and handle 512 have high structural strength while being lightweight, making it convenient for users to work. The handle 512 is fixedly connected to the movable shaft 503 by welding to ensure that the connection between the handle 512 and the movable shaft 503 has sufficient strength and is not easy to break or be damaged.
[0039] The hot air blower 9 can deliver hot air into the main body 2 of the device to assist in the hot air drying of automotive plastic parts, thereby improving the drying effect and efficiency. Specific Implementation Example 2:
[0041] Reference Figure 5 and Figure 6 In a preferred embodiment, the auxiliary uniform drying mechanism 6 includes a fixed toothed plate 601 and a transmission gear 602. Multiple fixed toothed plates 601 and transmission gears 602 are provided. Multiple fixed toothed plates 601 are fixedly installed in a ring array on the inner wall of the device body 2. The transmission gear 602 is fixedly fitted on the outside of the hanging rod 504. The fixed toothed plates 601 and the transmission gear 602 are located at the same plane height. The side of the fixed toothed plate 601 away from the inner wall of the device body 2 is provided with teeth that match the transmission gear 602.
[0042] In the specific implementation process, during operation, the drive motor 501 drives the rotating shaft seat 502 to rotate. The rotation of the rotating shaft seat 502 can drive multiple hanging rods 504 to rotate, thereby driving the transmission gear 602 to perform circumferential motion. When the transmission gear 602 meshes with the fixed tooth plate 601, the meshing between the fixed tooth plate 601 and the transmission gear 602 can drive the transmission gear 602 to rotate at a certain angle, thereby driving the hanging rods 504 to rotate at a certain angle. Therefore, it can drive multiple automotive plastic parts to rotate at a certain angle, thereby effectively improving the drying uniformity of multiple automotive plastic parts by the heating tube 4.
[0043] Working principle: During operation, the top cover 3 can be removed by lifting it upwards. Then, by holding the lifting handle 512, the movable shaft 503 can be pulled out from the rotating shaft seat 502 until it separates from the rotating shaft seat 502. The movable shaft 503 can then be removed from the main body 2 of the device. The movable shaft 503, together with multiple base plates 507, can be stably placed on the ground or other flat surfaces, thus exposing multiple hanging rods 504 and hooks 509. This greatly expands the operator's working space, allowing them to quickly and conveniently hang multiple automotive plastic parts directly or indirectly on the hooks 509. After hanging, the movable shaft 503 can be lifted by the lifting handle 512 and inserted into the rotating shaft seat 502. Insert the movable shaft 503 into the insertion slot 2, and align and engage the bottom plate 507 and top plate 508 with the limiting slot 506 until the bottom end of the movable shaft 503 abuts against the inner bottom surface of the insertion slot. This completes the installation of the movable shaft 503, allowing multiple automotive plastic parts to be quickly and conveniently placed into the interior of the device body 2. At this point, the top cover 3 can be closed, and the drive motor 501 and multiple heating tubes 4 can be started. The drive motor 501 drives the rotating shaft seat 502 to rotate, thereby driving multiple hanging rods 504 to rotate. With the help of multiple heating tubes 4, the automotive plastic parts can be effectively dried. The same principle applies when removing the plastic parts; simply repeat the above operation in reverse. In summary, this method saves time and effort and is highly efficient in hanging and removing plastic parts.
[0044] When the drive motor 501 drives the rotating shaft seat 502, the movable shaft 503, and the multiple hanging rods 504 to rotate, it can also drive the transmission gear 602 to make a circular motion. When the transmission gear 602 meshes with the fixed tooth plate 601, the meshing between the fixed tooth plate 601 and the transmission gear 602 can drive the transmission gear 602 to rotate at a certain angle, thereby driving the hanging rods 504 to rotate at a certain angle. Therefore, it can drive multiple automotive plastic parts to rotate at a certain angle, thereby effectively improving the drying uniformity of the heating tube 4 on multiple automotive plastic parts.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
