Technical Field
[0001] This utility model belongs to the technical field of mooncake turnover racks, and in particular relates to a dustproof mooncake turnover rack. Background Technology
[0002] The mooncake turnover frame is a support used in the mooncake production process. It can hold multiple layers of mooncakes, making it convenient to transfer and move mooncakes within the workshop. It can organize mooncakes in an orderly manner, facilitate production flow, and play a role in supporting and facilitating the transfer of mooncakes from production to subsequent processes, thereby improving production efficiency.
[0003] In the mooncake production process, the turnover frame currently used in our workshop lacks an effective dustproof structure. If there is dust or impurities in the workshop environment, they can easily fall onto the mooncakes when the turnover cart is pushed, which not only affects the hygiene of the mooncakes but may also damage their appearance and quality. Therefore, it is necessary to design a dustproof mooncake turnover rack that uses an infrared wave-activated lifting dustproof curtain design. Workers do not need to manually pull the dustproof curtain; they can trigger the lifting by waving their arms. This can greatly save time when the turnover rack is frequently in contact with mooncakes during handling, avoid manual contact with the dustproof curtain, and better ensure the hygiene of the mooncakes. Utility Model Content
[0004] The purpose of this utility model is to provide a dustproof mooncake turnover rack, which allows workers to raise and lower the rack by simply waving their arms without having to manually pull the dustproof curtain. This greatly saves time when mooncakes are frequently handled and come into contact with the turnover rack, avoids manual contact with the dustproof curtain, and better ensures the hygiene of the mooncakes, thus solving the aforementioned technical problems.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A dustproof mooncake turnover rack includes a turnover frame, a top plate fixedly connected to the top of the turnover frame, multiple detachable mooncake separator trays installed in the inner cavity of the turnover frame, a mounting cover fixedly connected to the front side of the top of the top plate, a mounting roller rotatably connected to the inner cavity of the mounting cover via a rotating shaft, a dust-proof curtain provided on the front side of the turnover frame, a mounting shell fixedly connected to the right side of the mounting cover, a rotating rod fixedly connected to the central axis of the right side of the mounting cover, the rotating rod penetrating into the inner cavity of the mounting shell and fixedly connected to a gear one, a linkage rod provided above the inner cavity of the mounting shell, a gear two fixedly connected to the bottom of the linkage rod, the gear one meshing with the gear two, a motor provided in the inner cavity of the mounting shell, the output shaft of the motor fixedly connected to the linkage rod, an infrared sensor installed on the right side of the turnover frame, and the infrared sensor electrically connected to the motor via a control box.
[0006] Preferably, pulleys are installed at all four corners of the bottom of the turnover frame.
[0007] Preferably, the left and right sides of the front of the turnover frame are fixedly connected to limit rails by bolts, and the two sides of the dust curtain are slidably connected to the inner diameter of the two limit rails.
[0008] Preferably, the surface of the mounting roller is fixedly connected with a plurality of connecting blocks, and the mounting roller is fixedly connected to the top of the dust curtain through the plurality of connecting blocks.
[0009] Preferably, a support plate is fixedly connected to the central axis of the inner cavity of the mounting shell, and the central axis of the support plate is rotatably connected to the linkage rod via a rotating shaft, and the motor is mounted on the top of the support plate.
[0010] The beneficial effects of this utility model are: 1. In this utility model, mooncakes are first placed on the top of the top plate. When a waving motion is detected, an infrared sensor receives the signal and transmits it to the control box. After processing, the control box sends a command to the motor, which starts. Through the combined use of the rotating rod, the mounting roller, and the dust curtain, the dust curtain slides downward on the front side of the turnover frame to block dust from the front side of the turnover frame. This allows workers to raise and lower the frame without manually pulling the dust curtain, simply by waving their arms. This greatly saves time when mooncakes are frequently in contact with the turnover frame during handling, avoids manual contact with the dust curtain, and better ensures the hygiene of the mooncakes. 2. By setting a limiting rail, the limiting rail guides the dust curtain when it slides within the inner diameter of the limiting rail, ensuring that the dust curtain will not float or sway when it covers the turnover frame on the front side, thus improving the smoothness of the dust curtain's sliding. 3. By setting up a support plate, the support plate limits the linkage rod when it rotates at the central axis of the support plate, ensuring that the linkage rod will not disengage from gear one when it drives gear two to rotate, thus improving the stability of the linkage rod.

Detailed Implementation
[0013] In the following description, embodiments of the dustproof mooncake turnover rack of this utility model will be described with reference to the accompanying drawings.
[0014] Figure 1-4 This invention illustrates a dustproof mooncake turnover rack according to an embodiment of the present invention. It includes a turnover frame 1, a top plate 2 fixedly connected to the top of the turnover frame 1, multiple detachable mooncake divider trays 3 installed in the inner cavity of the turnover frame 1, pulleys 4 installed at the four corners of the bottom of the turnover frame 1, a mounting cover 5 fixedly connected to the front side of the top of the top plate 2, mounting rollers 7 rotatably connected to the inner cavity of the mounting cover 5 via a rotating shaft, a dust-proof curtain 9 provided on the front side of the turnover frame 1, and limit rails 6 fixedly connected to the left and right sides of the front side of the turnover frame 1 by bolts. The dust curtain 9 is slidably connected to the inner diameter of two limiting rails 6 on both sides. The limiting rails 6 guide the dust curtain 9 as it slides within them, ensuring that it does not float or sway when covering the turnover frame 1 from the front, thus improving the smoothness of its sliding. Multiple connecting blocks 8 are fixedly connected to the surface of the mounting roller 7, which is then fixedly connected to the top of the dust curtain 9 via these blocks. The right side of the mounting cover 5 is fixedly connected to... A rotating rod 11 is fixedly connected to the central axis on the right side of the mounting housing 10 and the mounting cover 5. The rotating rod 11 passes through the inner cavity of the mounting housing 10 and is fixedly connected to a gear 12. A linkage rod 14 is provided above the inner cavity of the mounting housing 10, and a gear 15 is fixedly connected to the bottom of the linkage rod 14. Gear 12 and gear 15 mesh. A motor 16 is provided inside the inner cavity of the mounting housing 10, and the output shaft of the motor 16 is fixedly connected to the linkage rod 14. A support plate 13 is fixedly connected to the central axis of the inner cavity of the mounting housing 10. The motor 16 is mounted on the top of the support plate 13 and is rotatably connected to the linkage rod 14 via a rotating shaft. The support plate 13 limits the linkage rod 14 when it rotates at the central axis of the support plate 13, ensuring that the linkage rod 14 will not disengage from the gear 12 when it drives the gear 2 15 to rotate, thus improving the stability of the linkage rod 14. An infrared sensor 17 is installed on the right side of the turnover frame 1, and the infrared sensor 17 is electrically connected to the motor 16 via the control box.
[0015] Working Principle: When using this utility model, the newly made or ready-to-be-transferred mooncakes are first arranged in an orderly manner on the multi-layer mooncake separating tray 3 inside the turnover frame 1, ensuring even distribution to avoid stacking and compression. After the mooncake separating trays are in place, the arm is waved in the sensing area of the infrared sensor 17 on the right side of the turnover frame 1. The sensor 17 captures the non-contact trigger signal, which is transmitted to the control box through a preset circuit. After confirmation of validity, a start command is sent to the motor 16 at the top of the support plate 13 inside the mounting shell 10. After the motor 16 starts, the output shaft rotates and drives the linkage rod 14 to rotate through the coupling. The gear 15 at the bottom of the linkage rod 14 and... The gear 12 at the end of the rotating rod 11 meshes, thereby driving the gear 12 and the rotating rod 11 to rotate. The other end of the rotating rod 11 is fixed to the mounting roller 7 in the inner cavity of the mounting cover 5, driving the mounting roller 7 to rotate smoothly along the rotating shaft. The surface of the mounting roller 7 is connected to the top of the dust curtain 9 through multiple connecting blocks 8. As the mounting roller 7 rotates, the dust curtain 9 is gradually released and slides down to the front side of the turnover frame 1 under the action of gravity. Its two sides slide along the inner side of the limiting rail 6 on the front side of the turnover frame 1 to ensure smooth sliding. Finally, the dust curtain 9 slides down to the bottom of the turnover frame 1, completely covering the front opening area to form a dust barrier, isolating the mooncakes from workshop dust and impurities.
[0016] In summary, this dustproof mooncake turnover rack first places the mooncakes on top of the top plate 2. When a waving motion is detected, the infrared sensor 17 receives the signal and transmits it to the control box. After processing, the control box sends a command to the motor 16, which starts the motor. Through the coordinated use of the rotating rod 11, the mounting roller 7, and the dust curtain 9, the dust curtain 9 slides downward on the front side of the turnover frame 1, blocking dust from the front side of the turnover frame 1. This allows workers to raise and lower the rack without manually pulling the dust curtain; they can simply wave their arms to trigger the lifting mechanism. This significantly saves time when handling mooncakes and frequently touching the turnover rack, avoids manual contact with the dust curtain, and better ensures the hygiene of the mooncakes.
