Description

Technical Field

[0001] This utility model belongs to the field of tofu skin processing technology, specifically an automated tofu skin folding device. Background Technology

[0002] Tofu skin is a common soy product. It is usually made from soybean varieties with high protein content and plump grains, such as Northeast soybeans, which provide rich protein and other nutrients for tofu skin. During the processing of tofu skin, it needs to be folded and then picked up by a gripping mechanism, such as a gripping moving plate with suction cups, and then transferred to a designated position by a conveying cylinder and other devices.

[0003] Meanwhile, application number "CN201336910Y" describes a tofu skin machine, including a frame and a conveyor belt horizontally mounted on the frame; a bean curd feeding device is mounted on the frame above the feed end of the conveyor belt; a tray frame driven by a power source to move back and forth is mounted on the frame guide rail below the discharge end of the conveyor belt, and a tray is mounted on the tray frame and driven by a motor to lift and lower; a limit switch is mounted at the discharge end of the conveyor belt, and the switch contacts of the limit switch are connected in series in the power supply line of the tray drive motor; a light-emitting diode controlled by the limit switch is mounted on the limit switch. The advantages of this invention are high automation and production efficiency. By using stirring mechanisms respectively located in the outlet and inside the slurry cylinder, it overcomes the sedimentation and slurry-water separation phenomena that occur during production, greatly improving the quality of the tofu skin. The red light-emitting diode on the limit switch flashes once, recording the number of folded layers of the tofu skin and providing a visually appealing effect.

[0004] The above-mentioned technical solution requires pushing the tofu skin to a designated position during use. However, as the tofu skin is removed layer by layer, it cannot be guaranteed that the tofu skin will always be in the designated position, which affects the normal folding process. At the same time, the existing folding mechanism is prone to causing wrinkles in the tofu skin.

[0005] Therefore, an automated tofu skin folding device is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an automated tofu skin folding device, which has the advantages of keeping the tofu skin in a fixed position and preventing wrinkles from forming when folded.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automated tofu skin folding device, including an electrical control box, a rotating frame fixedly connected to the outside of the electrical control box, a stabilizing plate fixedly connected to the inside of the rotating frame, and a feeding mechanism provided inside the rotating frame;

[0008] The feeding mechanism includes a feeding trough. An electric telescopic rod is fixedly connected to the inner bottom wall of the rotating frame. A lifting rod is fixedly connected to the top of the electric telescopic rod. A storage trough is fixedly connected to the top of the lifting rod. A return spring is fixedly connected to the inner bottom wall of the storage trough. A storage plate is fixedly connected to the top of the return spring.

[0009] Preferably, the operating frame is provided with a folding mechanism, which includes a slide rail. An electric slider is slidably connected to the outside of the slide rail. A second electric telescopic rod is fixedly connected to the bottom of the electric slider. A moving rod is fixedly connected to the bottom of the second electric telescopic rod. A suction cup is fixedly connected to the bottom of the moving rod. A material trough is opened inside the stabilizing plate. A collection box is fixedly connected to the bottom of the stabilizing plate. A sealing plate is installed in the side wall of the collection box. A folding rod is fixedly connected inside the operating frame.

[0010] Preferably, the first electric telescopic rod is fixedly connected to the inner bottom wall of the operating frame. The length and width of the storage trough are smaller than the length and width of the feeding trough. The first electric telescopic rod is started through the electrical control box, thereby causing the first electric telescopic rod to drive the lifting rod to move.

[0011] Preferably, the storage slot is located directly below the feeding slot, and the return springs are symmetrically distributed between the storage plate and the inner bottom wall of the storage slot. When the lifting rod moves upward, it can drive the storage slot to move into the feeding slot.

[0012] Preferably, the slide rails are fixed and symmetrically distributed between the rotating frames, and the suction cups are movably connected above the stabilizing plate via a second electric telescopic rod. The electric slider is activated by the electrical control box, thereby causing the electric slider to move on the outside of the slide rails.

[0013] Preferably, the suction cups are symmetrically distributed above the stabilizing plate, and the suction cup power source is connected to the suction pump. By activating the second electric telescopic rod, the second electric telescopic rod drives the suction cups to move to the top of the tofu skin.

[0014] Preferably, the collection box is fixedly connected to the bottom of the material trough, and the folding rod is located at the middle position above the material trough. After the tofu skin is folded by the folding rod, it can prevent wrinkles from forming.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model incorporates an electrical control box with a rotating frame fixedly connected to its outer side. First, tofu skin is placed on top of the storage plate. This compresses the return spring at the bottom of the storage plate, placing it inside the storage trough. Then, the electrical control box activates the first electric telescopic rod, which moves the storage trough into the feeding trough. As the tofu skin is removed layer by layer, the return spring causes the storage plate to move the tofu skin upwards, keeping it in a fixed position.

[0017] 2. This utility model incorporates a rotating frame. When folding tofu skin is required, the second electric telescopic rod is activated via the electrical control box. This causes the moving rod to move the suction cup to the top of the tofu skin. The suction cup then picks up the tofu skin. The electric slider moves outside the slide rail via the electrical control box, allowing the suction cup to move the tofu skin to the top of the folding rod. The second electric telescopic rod then moves the tofu skin above the folding rod. The suction is then turned off, allowing the tofu skin to be folded outside the folding rod. After folding, the tofu skin is stored inside the collection box. After folding, the folded tofu skin can be collected and removed by opening the sealing plate, thus preventing wrinkles.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown, this utility model provides an automated tofu skin folding device, including an electrical control box 1, a rotating frame 2 fixedly connected to the outside of the electrical control box 1, a stabilizing plate 3 fixedly connected to the inside of the rotating frame 2, and a feeding mechanism 4 provided inside the rotating frame 2.

[0025] The feeding mechanism 4 includes a feeding trough 41. An electric telescopic rod 42 is fixedly connected to the inner bottom wall of the rotating frame 2. A lifting rod 43 is fixedly connected to the top of the electric telescopic rod 42. A storage trough 44 is fixedly connected to the top of the lifting rod 43. A return spring 45 is fixedly connected to the inner bottom wall of the storage trough 44. A storage plate 46 is fixedly connected to the top of the return spring 45.

[0026] Specifically, the operating frame 2 is equipped with a folding mechanism 5, which includes a slide rail 51. An electric slider 52 is slidably connected to the outside of the slide rail 51. A second electric telescopic rod 53 is fixedly connected to the bottom of the electric slider 52. A moving rod 54 is fixedly connected to the bottom of the second electric telescopic rod 53. A suction cup 55 is fixedly connected to the bottom of the moving rod 54. A material trough 56 is opened inside the stabilizing plate 3. A collection box 57 is fixedly connected to the bottom of the stabilizing plate 3. A sealing plate 58 is installed in the side wall of the collection box 57. A folding rod 59 is fixedly connected inside the operating frame 2.

[0027] like Figures 1 to 4 As shown, the first electric telescopic rod 42 is fixedly connected to the inner bottom wall of the operating frame 2. The length and width of the storage trough 44 are smaller than the length and width of the feeding trough 41. The first electric telescopic rod 42 is started through the electrical control box 1, thereby causing the first electric telescopic rod 42 to drive the lifting rod 43 to move.

[0028] Furthermore, the storage slot 44 is located directly below the loading slot 41, and the return springs 45 are symmetrically distributed between the storage plate 46 and the inner bottom wall of the storage slot 44. When the lifting rod 43 moves upward, it can drive the storage slot 44 to move into the interior of the loading slot 41.

[0029] like Figures 1 to 4 As shown, the slide rails 51 are fixed and symmetrically distributed between the rotating frames 2. The suction cups 55 are movably connected to the top of the stabilizing plate 3 via the second electric telescopic rod 53. The electric slider 52 is started by the electric control box 1, so that the electric slider 52 moves outside the slide rails 51.

[0030] It is worth noting that the suction cups 55 are symmetrically distributed above the stabilizing plate 3, and the power source of the suction cups 55 is connected to the suction pump. By activating the second electric telescopic rod 53, the second electric telescopic rod 53 drives the suction cups 55 to move to the top of the tofu skin.

[0031] like Figures 1 to 4 As shown, the collection box 57 is fixedly connected to the bottom of the material trough 56, and the folding rod 59 is located in the middle of the top of the material trough 56. After the tofu skin is folded by the folding rod 59, it can prevent wrinkles from forming.

[0032] Working principle and process: An electrical control box 1 is installed, and a rotating frame 2 is fixedly connected to the outside of the electrical control box 1. First, the tofu skin is placed on top of the storage plate 46. At this time, the return spring 45 at the bottom of the storage plate 46 is squeezed, so that it is located inside the storage trough 44. Then, the electrical control box 1 starts the first electric telescopic rod 42, which moves the storage trough 44 into the feeding trough 41. As the tofu skin is removed layer by layer, the return spring 45 causes the storage plate 46 to move the tofu skin upward, so that the tofu skin is always in a fixed position. With the rotating frame 2, when it is necessary to fold the tofu skin, the electrical control box 1 first starts the tofu skin. Box 1 activates the second electric telescopic rod 53, causing the moving rod 54 to move the suction cup 55 to the top of the tofu skin. At this time, the suction cup 55 is activated to pick up the tofu skin. Then, the electric slider 52 moves outside the slide rail 51 via the control box 1, allowing the suction cup 55 to move the tofu skin to the top of the folding rod 59. The second electric telescopic rod 53 moves the tofu skin above the folding rod 59. At this time, the suction is turned off, allowing the tofu skin to be folded outside the folding rod 59. After folding, it is stored inside the collection box 57. After folding, the folded tofu skin can be collected and taken out by opening the sealing plate 58, thus preventing wrinkles.
