Description

Technical Field

[0001] This utility model belongs to the field of drying oven technology, specifically an automatic tray loading and unloading device for a drying oven. Background Technology

[0002] A drying oven is an industrial device used to remove moisture or solvents from materials. It is widely used in food processing, pharmaceuticals, chemicals, electronics, agriculture, and other fields. Its core function is to use heating and ventilation systems to dry materials under controlled temperature, humidity, and airflow conditions. Currently, products are typically placed on trays, which are then manually placed into the drying oven. After drying, the trays are removed. However, manual handling greatly increases the labor intensity for workers, and the high temperature inside the drying oven can easily cause burns during handling. Therefore, we propose an automatic tray loading and unloading device for drying ovens to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide an automatic tray loading and unloading device for drying ovens, so as to solve at least one aspect of the problems and defects mentioned in the background art.

[0004] It includes a platform and a lifting mechanism. The platform is mounted on the lifting mechanism. A guide rail and a toothed rail are mounted parallel to each other on the top of the platform. The toothed rail has teeth evenly distributed on the side near the guide rail. The first end of the guide rail and the toothed rail is mounted on one end of the platform, and the second end of the guide rail and the toothed rail is mounted on the other end of the platform. A slider is slidably mounted on the guide rail. A rotary drive motor is mounted on the slider. The output end of the rotary drive motor is connected to a drive gear, which meshes with the teeth of the toothed rail.

[0005] The rotary drive motor is equipped with a claw, the fixed end of which is mounted on the rotary drive motor, and the hook-grabbing end of which is set towards the end of the guide rail.

[0006] Furthermore, the lifting mechanism includes a base, a platform, and a rotary motor. Several columns are mounted on the base, and a cover plate is mounted on the end of each column away from the base. A first limit block is mounted on one side of the cover plate. The rotary motor is fixedly mounted on the base, and a threaded rod is connected to the output end of the rotary motor. The end of the threaded rod is rotatably mounted on the first limit block. The platform is mounted on the columns and can move up and down. A movable block is fixedly mounted on one side of the platform. A through hole is opened on the movable block, and a nut is fixedly installed in the through hole. The nut is screwed to the threaded rod.

[0007] Furthermore, casters are installed at the bottom of the base.

[0008] Furthermore, when there is one or more platforms, and the platforms are arranged symmetrically in a vertical arrangement.

[0009] Furthermore, two receiving platforms are provided on the platform, and the receiving platforms are symmetrically arranged with the guide rail as the center.

[0010] Furthermore, a second limiting block 204 is provided at both ends of the guide rail 201.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This solution includes a platform and a lifting device to control its movement. Parallel guide rails and geared rails are installed on the platform. A rotary drive motor is slidably mounted on the guide rails via a slider. The output of the rotary drive motor is connected to a drive gear, which meshes with the geared rails. The forward and reverse rotation of the rotary drive motor drives the drive gear to rotate in the same direction, allowing the slider and its rotary drive motor to move back and forth along the guide rails. The rotary drive motor is equipped with a hook; when loading material, simply place the tray on the platform, and the slider will move the hook towards the drying chamber. The tray is automatically moved into the drying chamber by the hook end. When the tray needs to be removed, the platform height is adjusted by the lifting device, and the hook continues to move along the guide rail towards the drying chamber by the rotary drive motor until the curved part of the hook end aligns with the groove of the tray handle. The platform height is then adjusted again by the lifting device so that the curved part of the hook end hooks the tray handle. The hook is then moved away from the drying chamber by the rotary drive motor, thus bringing the tray back to the platform. This method enables automatic tray entry and exit from the drying chamber, improving work efficiency and reducing the risk of burns. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-5 As shown in the embodiment of this utility model, an automatic tray loading and unloading device for a drying oven includes a platform 2 and a lifting mechanism. The platform 2 is mounted on the lifting mechanism. A guide rail 201 and a toothed rail 202 are mounted parallel to each other on the top of the platform 2. The toothed rail 202 has teeth evenly distributed on the side near the guide rail 201. The first ends of the guide rail 201 and the toothed rail 202 are mounted on one end of the platform 2, and the last ends of the guide rail 201 and the toothed rail 202 are mounted on the other end of the platform 2. A slider (not shown) is slidably mounted on the guide rail 201. A rotary drive motor 301 is mounted on the slider. The output end of the rotary drive motor 301 is associated with a drive gear 302, and the drive gear 302 meshes with the teeth of the toothed rail 202.

[0023] The rotary drive motor 301 is equipped with a hook 3. The fixed end of the hook 3 is installed on the rotary drive motor 301. The hook 3 is positioned with the hooking end facing the end of the guide rail 201. It should be noted that when installing the hook 3, the bent part of the hooking end should be bent upwards.

[0024] In use, place the device at the inlet of the drying chamber (not shown), with the end of the guide rail 201 facing the inlet. Place the tray 4 on the platform 2, between the hook 3 and the drying chamber. Start the rotary drive motor 301. The rotation of the rotary drive motor 301 drives the drive gear 302 to rotate. Since the drive gear 302 meshes with the gear rail 202, the rotary drive motor 301 will move along the guide rail towards the inlet of the drying chamber via the slider, thereby causing the end of the hook 3 to grab the tray 4 and push the tray 4 into the drying chamber. After drying is complete, [the device is then removed from the drying chamber]. The lifting mechanism controls the platform 2 to move downwards, causing the hook 3 to be vertically misaligned with the handle 401 of the tray 4. The hook 3 continues to move along the slide rail towards the drying chamber until the curved part of the hook 3 reaches directly below the handle 401 of the tray 4. Then, the lifting mechanism controls the platform 2 to move upwards, causing the curved part of the hook 3 to engage with the groove in the handle 401 of the tray 4. At this point, the rotary drive motor 301 is controlled to rotate in the opposite direction, causing the hook 3 to move along the slide rail away from the drying chamber, thereby pulling the tray 4 back to the platform 2. It should be noted that both the lifting device and the rotary drive motor 301 are uniformly controlled by an external control device (not shown).

[0025] The above design allows for the automatic movement of the drying oven tray in and out of the drying oven, thereby improving work efficiency and reducing the risk of burns.

[0026] The lifting mechanism includes a base 5, a platform 2, and a rotary motor 104. Several columns 1 are mounted on the base 5. A cover plate 105 is mounted on the end of each column 1 away from the base. A first limiting block 103 is mounted on one side of the cover plate 105. The rotary motor 104 is fixedly mounted on the base 5. A threaded rod 101 is connected to the output end of the rotary motor 104. The end of the threaded rod 101 is rotatably mounted on the first limiting block 103 via a bearing. The platform 2 is mounted on the columns 1 and can move up and down. A movable block 102 is fixedly mounted on one side of the platform 2. A through hole is opened on the movable block 102, and a nut (not shown) is fixedly installed in the through hole. The nut is screwed to the threaded rod 101. By rotating the rotary motor 104 forward and backward, the platform 2 can be controlled to move up and down along the columns 1 to adjust the height of the platform 2.

[0027] In one embodiment, see Figure 1 As shown, a caster wheel 501 is installed at the bottom of the base 5. The distance between the device body and the inlet of the drying chamber can be adjusted at any time by means of the caster wheel 501. The caster wheel 501 is equipped with a limiter (existing technology). When it is not necessary to move, the caster wheel 501 can be fixed by the limiter to keep the device stable.

[0028] In one embodiment, there is one or more platforms 2. When there are multiple platforms 2, the different platforms 2 are arranged symmetrically up and down. When the drying box has a multi-layer structure, the number of platforms 2 can be determined according to the number of layers of the drying box. One platform 2 corresponds to one layer of the drying box. Multiple platforms 2 work at the same time to improve work efficiency. It should be noted that the spacing between adjacent platforms 2 needs to be adjusted according to the spacing between adjacent layers of the drying box to ensure that each platform 2 can be aligned with the entrance of the drying box layer.

[0029] In one embodiment, see Figure 3 As shown, the platform 2 is provided with two receiving platforms 203. The receiving platforms 203 are symmetrically arranged with the guide rail 201 as the center. The top surface of the receiving platform 203 is lower than the bottom surface of the hook 3 in terms of horizontal height. The receiving platform 203 can better support the pallet 4, making the movement of the pallet 4 smoother.

[0030] In one embodiment, see Figure 3 As shown, a second limiting block 204 is provided at both ends of the guide rail 201. The top surface of the second limiting block 204 is lower than the top surface of the guide rail 201 and higher than the bottom surface of the slider. The second limiting block 204 can reduce the probability of the slider derailing.

[0031] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
