Abstract
Description
Technical Field
[0001] This utility model relates to the field of tofu forming mold technology, specifically to a tofu forming mold used in tofu processing. Background Technology
[0002] In the tofu processing, the forming process of tofu blanks (the intermediate product after soy milk coagulation) has a significant impact on the final tofu quality.
[0003] Existing tofu forming molds lack an effective directional flow structure in the mold cavity when processing tofu blocks. After the tofu blocks are poured in, they tend to accumulate locally due to their own viscosity and gravity, making it difficult to distribute them evenly within the mold. In addition, traditional molds mostly rely on manual vibration to adjust the distribution of tofu blocks. Not only is it difficult to control the vibration frequency and amplitude, but there is also a lack of a stable reset mechanism after vibration, which makes the mold position prone to displacement, further exacerbating the uneven distribution of tofu blocks. These problems directly lead to uneven stress on different parts of the tofu during subsequent pressing, resulting in significant differences in firmness and seriously affecting the consistency of the tofu's texture and quality stability. Therefore, this utility model proposes a tofu forming mold for tofu processing to solve the above problems. Utility Model Content

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the present invention provides a tofu forming mold for tofu processing, which has the following beneficial effects:
[0017] 1. This utility model uses a servo motor to drive the cam to rotate, and a reset mechanism composed of a spring and a slider can drive the lower mold to generate stable and controllable vibration. This effectively solves the problems of difficult control of vibration frequency and amplitude and easy position displacement after vibration in traditional molds. It can help the tofu block overcome the effects of stickiness and gravity to spread evenly, avoid local accumulation, and lay the foundation for the uniformity of compactness in subsequent pressing.
[0018] 2. This utility model forms an efficient drainage path by utilizing the through holes of the fixed plate, the drainage groove, and the drainage holes of the pressure plate.

[0024] This utility model provides a technical solution for tofu forming molds used in tofu processing:
[0025] Please see Figure 1-3 A tofu forming mold for tofu processing includes a base plate 1. Slide rods 8 are fixedly connected to the four corners of the upper end of the base plate 1. The outer walls of the slide rods 8 are slidably connected to a lower mold 2. An installation groove is opened on one side wall of the lower mold 2, and a baffle 3 is snapped into the installation groove. A side plate 5 is fixedly connected to the upper end of the base plate 1. An electric telescopic rod 6 is fixedly connected to the upper end of the side plate 5. A pressure plate 7 is fixedly connected to the telescopic end of the electric telescopic rod 6, and the pressure plate 7 is slidably connected to the lower mold 2. A shaking mechanism is installed on the upper end of the base plate 1, and a reset mechanism is installed on the outer wall of the slide rods 8.
[0026] The vibration mechanism is used to drive the lower mold 2 to vibrate;
[0027] The reset mechanism is used to reset the lower mold 2 after it vibrates.
[0028] Furthermore, by sliding the slide bar 8 with the lower mold 2, combined with the synergistic effect of the shaking mechanism and the reset mechanism, the problem of uneven flow rate during soy milk injection can be effectively solved.
[0029] The shaking mechanism includes a cam 12, and a slide groove 11 is provided through the end face of the base plate 1. The cam 12 is rotatably connected in the slide groove 11, and the flange of the cam 12 contacts the bottom surface of the lower mold 2.
[0030] Furthermore, when the cam 12 rotates in the slide groove 11, the contact between its flange and the bottom surface of the lower mold 2 can cause the lower mold 2 to vibrate. This vibration can help the soy milk injected into the lower mold 2 overcome the influence of gravity and surface tension, and spread quickly and evenly, avoiding local accumulation.
[0031] The reset mechanism includes two sets of sliders 9 sleeved on the outer wall of each set of slide rods 8. Each set of slide rods 8 is sleeved with a spring 10. The two ends of the spring 10 are fixedly connected to the outer walls of the two sets of sliders 9 respectively. The upper slider 9 is in contact with the lower end face of the lower mold 2.
[0032] Furthermore, during the vibration of the lower mold 2 driven by the cam 12, the spring 10 can apply a reset force to the lower mold 2 through the slider 9, ensuring that the lower mold 2 can quickly return to its initial position after vibration, reducing operational complexity and improving processing efficiency.
[0033] A fixing plate 13 is fixedly connected to the inner wall of the lower mold 2. A drain groove 14 is opened inside the lower mold 2. Multiple sets of through holes are opened through the end face of the fixing plate 13, and the through holes extend into the drain groove 14.
[0034] Furthermore, the through holes on the fixing plate 13 can serve as a directional flow path to guide the soy milk to be evenly distributed during injection. At the same time, the water in the soy milk can quickly flow into the drain tank 14 through the through holes and be discharged, which helps to ensure that the firmness of each part of the tofu is consistent after pressing.
[0035] The inner wall of the mounting groove is provided with a limiting groove, and the outer wall of the baffle 3 is integrally formed with a limiting block, which slides in the limiting groove; multiple sets of drainage holes are provided through the end face of the pressure plate 7.
[0036] Furthermore, the limiting block on the outer wall of the baffle 3 cooperates with the limiting groove on the inner wall of the mounting groove to ensure that the baffle 3 is installed firmly, and the baffle 3 can be set up to quickly extract the tofu after it is formed.
[0037] A servo motor 4 is fixedly connected to the side wall of the base plate 1, and the output shaft end of the servo motor 4 is fixedly connected to the cam 12 coaxially.
[0038] In practical use, the working principle of this utility model is as follows:
[0039] When the operator uses the tofu forming mold, the baffle 3 is first engaged in the mounting groove of the lower mold 2 by the cooperation of the limiting block and the limiting groove to ensure that it is installed firmly.
[0040] Next, the solidified tofu block is poured into the lower mold 2. Since the inner wall of the lower mold 2 is fixed with a fixing plate 13, the tofu block will first fall onto the fixing plate 13. The servo motor 4 is started, and its output shaft drives the cam 12 to rotate in the slide groove 11. The flange of the cam 12 continuously contacts the bottom surface of the lower mold 2 and lifts the lower mold 2, causing the lower mold 2 to slide upward along the slide rod 8. When the flange of the cam 12 rotates away from the bottom surface of the lower mold 2, under the action of the reset mechanism, the spring 10 applies a downward force to the lower mold 2 through the slider 9, driving the lower mold 2 to quickly reset. This process is repeated, and the lower mold 2 generates continuous vibration.
[0041] During vibration, the tofu block is subjected to vibrational force, which overcomes its own stickiness and surface tension, allowing it to spread evenly on the fixed plate 13 and preventing local accumulation. Simultaneously, the electric telescopic rod 6 is activated, its telescopic end pushing the pressure plate 7 downwards along the inner wall of the lower mold 2 to press the tofu block. Water generated during pressing is partially discharged into the drainage trough 14 through the through-holes on the fixed plate 13, and the remaining portion is directly discharged through the drainage holes on the end face of the pressure plate 7, ensuring that water is quickly removed from the tofu block.
[0042] As the electric telescopic rod 6 continues to extend and retract, the pressure plate 7 continuously applies pressure to the tofu block, ensuring that all parts of the tofu block are subjected to uniform pressing force. Combined with the continuous vibration of the lower mold 2, this ultimately forms tofu blocks with uniform density. After pressing is complete, the servo motor 4 and the electric telescopic rod 6 are turned off, and the baffle 3 is pulled out of the mounting slot, allowing for easy removal of the formed tofu blocks.
[0043] In summary, the shaking and resetting mechanisms in this device ensure the uniform distribution of tofu blocks. The through holes in the fixed plate 13, the drainage groove 14, and the drainage holes in the pressure plate 7 work together to achieve efficient drainage. The pressure plate 7 driven by the electric telescopic rod 6 ensures the stability of the pressing pressure. This effectively solves the tofu quality problems caused by uneven distribution of tofu blocks and poor drainage in traditional molds. At the same time, it is easy to operate and improves the efficiency and quality stability of tofu processing.
[0044] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
