Description

Technical Field

[0001] This utility model relates to the field of soybean food processing, specifically a tofu and douhua forming device. Background Technology

[0002] In the field of soy product processing, douhua (soybean curd) and tofu are two widely used products, with significant commonalities and specific differences in their processing procedures. Specifically, both douhua and tofu use soy milk as their base material, and their core processes include coagulating the soy milk with a coagulant. After the soy milk forms a solidified material, it is then pressed into shape to obtain the final product. The key difference lies only in the process parameters of the pressing stage. Tofu requires a longer pressing time than douhua, and the pressure applied during pressing must be greater than that for douhua. By controlling these different pressing parameters, the two products achieve differences in taste, texture, and density.

[0003] In current industrialized production scenarios, factories typically use presses as the core pressing equipment to ensure production efficiency and product molding stability when making tofu and pudding. This is to complete the pressing and molding of solidified materials. As industry demands for equipment performance increase, related technologies are constantly evolving. Among them, Chinese utility model patent application number CN202020503677.8 discloses a tofu pressing and molding device. This device uses a guide groove and slides a molding frame above it. When the molding frame slides to a position corresponding to the pressing plate, the pressing plate presses and shapes the solidified material within the molding frame, providing a concrete solution for the industrial pressing of tofu.

[0004] However, practical application analysis revealed that the aforementioned tofu compaction molding equipment still has significant technical shortcomings during use, making it difficult to meet the current factory's needs for efficient and flexible production. Firstly, the equipment lacks an effective rapid positioning mechanism. Since the forming frame is only assembled onto the guide groove by sliding, in actual operation, the position of the forming frame needs to be adjusted manually or by simple mechanical structures to achieve its alignment with the pressing plate. This process not only makes it difficult to guarantee alignment accuracy and easily leads to misalignment between the forming frame and the pressing plate, but also consumes a lot of adjustment time, resulting in low overall efficiency of the pressing and forming process, making it impossible to achieve rapid pressing and forming, and seriously restricting the overall capacity of the production line.

[0005] Secondly, the equipment lacks versatility and cannot adapt to diverse production needs. The pressing plates and forming frames in this equipment are designed with fixed structures, and their shapes, dimensions, and other specifications are fixed. It is impossible to change the models of the pressing plates and forming frames according to the actual production requirements for different specifications and shapes of tofu or soy products. When the factory needs to produce products of different sizes or shapes, the entire forming equipment must be replaced, which not only increases equipment investment costs but also requires a significant amount of time for disassembly, assembly, and debugging, greatly reducing production flexibility and adaptability. Utility Model Content

[0006] Therefore, in order to solve the above-mentioned shortcomings, this utility model provides a tofu forming device. The forming device supports the forming mold through a base, which can ensure that the forming mold can slide linearly and be quickly fixed on the base. This facilitates the correspondence with the lifting mechanism and the pressing plate above, so as to achieve pressing and shaping. At the same time, through the detachable connection of the pressing plate and the pad that is movably installed on the base, it is easy to position and press forming molds of different sizes, thereby effectively improving practicality.

[0007] This utility model is implemented as follows: a tofu forming device includes a lifting mechanism installed on a base; The pressing plate is detachably connected to the lifting end of the lifting mechanism; The molding die is placed on the base and slides linearly or is automatically fixed on the base; The pad is detachably mounted on the base to limit and fix the forming molds of different sizes and to keep the position corresponding to the pressing plates of different sizes.

[0011] Preferably, the base includes a base body, on which a sliding placement groove is formed. One end of the sliding placement groove extends to the outside of the base body, and the other end of the sliding placement groove is an inwardly converging inclined surface. The inclined surface has a V-shaped structure and its center line is perpendicular to the axis of the pressing cake. Several receiving grooves are formed along a straight line on the inner bottom of the sliding placement groove. The receiving grooves point to the inclined surface and multiple rotating rollers are evenly arranged in the receiving grooves. A drainage groove is provided at the inner end of the sliding placement groove near the inclined surface. One end of the drainage groove extends to the outside of the base body, and the other end is connected to the receiving groove.

[0012] Preferably, an installation groove is provided on the inner side of the sliding placement groove of the substrate, one side of the pad is provided with an installation block that matches the installation groove, and the other side of the pad is provided with an installation groove.

[0013] Preferably, the cross-sectional shape of the mounting groove and the mounting block is dovetail-shaped.

[0018] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of this utility model and are not intended to limit this utility model in any way. The accompanying drawings in this utility model are only for illustrative purposes and to facilitate understanding of the embodiments and are not intended to limit this utility model in any way.

[0019] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0020] As described in the background section, existing tofu forming devices are not convenient for quickly positioning the forming frame and the pressing equipment during pressing. They require repeated manual adjustments to achieve accurate positioning, which is quite troublesome. Furthermore, existing forming devices cannot adjust the size of the pressed cake or perform rapid positioning according to different forming molds, making them impractical.

[0021] For the reasons stated above, please refer to the appendix for solutions to these problems. Figure 1 and attached Figure 2 This utility model provides a tofu forming device, including a lifting mechanism installed on a base 1; The pressing plate 7 is detachably connected to the lifting end of the lifting mechanism; The forming mold 8 is placed on the base 1 and slides linearly or is automatically fixed on the base 1; The pad 9 is detachably mounted on the base 1 to limit and fix the forming molds 8 of different sizes and to maintain the position corresponding to the pressing cakes 7 of different sizes.

[0022] Please refer to the appendix carefully. Figure 3 In this embodiment, the lifting mechanism specifically consists of two sets of support frames 2, which are arranged opposite each other and vertically fixed on the base 1; Mounting bracket 3 is movably connected between two sets of support brackets 2 and allows for height adjustment; The lifting cylinder 4 is fixed on the mounting bracket 3 and its telescopic end extends downward through the mounting bracket 3; The driver 5 is located on the outer end of the base 1 to provide air to the lifting cylinder 4.

[0023] To facilitate the adjustment of the height of the lifting mechanism and thus adapt to the molding molds of different heights for pressing and molding, in this embodiment, several fixing holes of equal diameter are equally spaced along the vertical direction on the support frame 2, and the mounting frame 3 is fixed to the support frame 2 by means of pins passing through the fixing holes.

[0024] To facilitate the detachable connection of the pressed cake and adapt it to different forming molds for pressing, in this embodiment, the telescopic end of the lifting cylinder 4 is provided with a threaded connector. The pressed cake 7 is threadedly connected to the threaded connector of the lifting cylinder 4. A guide post 6 is also provided through the mounting frame 3. The end of the guide post 6 is connected to the pressed cake 7 by bolts and nuts.

[0025] As mentioned above, setting guide posts not only ensures a stable connection between the pressing plate and the threaded connector, but also prevents the pressing plate from rotating arbitrarily during lifting and lowering, thus affecting the pressing process.

[0026] Please see the appendix Figure 4 To facilitate the linear sliding and rapid positioning of the forming mold, thereby ensuring precise alignment with the pressing cake above, in this embodiment, the base 1 includes a base 101. A sliding placement groove 102 is provided on the base 101. One end of the sliding placement groove 102 extends to the outside of the base 101, and the other end of the sliding placement groove 102 is an inwardly converging inclined surface. The inclined surface has a V-shaped structure and its center line is perpendicularly intersecting the axis of the pressing cake 7. Several receiving grooves 103 are provided in a straight line along the inner bottom of the sliding placement groove 102. The receiving grooves 103 point towards the inclined surface, and multiple rotating rollers 104 are evenly arranged in the receiving grooves 103. A drainage groove 105 is provided at the inner end of the sliding placement groove 102 near the inclined surface. One end of the drainage groove 105 extends to the outside of the base 101, and the other end is connected to the receiving groove 103.

[0027] As described above, the rollers allow the molding die to be placed in the sliding slot and then slide in a straight line, facilitating quick positioning at the inclined surface. Furthermore, by rationally designing the inclined surface as a V-shaped structure, it can not only position circular molding dies but also quickly position rectangular or square molding dies, thereby effectively improving the practicality of the device.

[0028] Please see the appendix Figure 4 and attached Figure 5To facilitate the installation of a pad on the base to control the size of the sliding placement groove, thereby facilitating linear movement and rapid positioning of molding dies of different sizes, in this embodiment, an installation groove 106 is provided on the inner side of the sliding placement groove 102 of the base 101, and one side of the pad 9 is provided with an installation block that matches the installation groove 106, while the other side of the pad 9 is provided with an installation groove.

[0029] In this embodiment, the cross-sectional shape of the mounting groove 106 and the mounting block is dovetail-shaped.

[0030] In this embodiment, the mounting groove 106 and the mounting block are magnetically attached and fixed together.

[0031] This forming device can be connected to an external conveying mechanism (through the open end of the sliding placement groove 102). By combining the drive cylinder to push the forming mold to move on the sliding placement groove 102 and the conveying mechanism, the automatic forming process of tofu can be realized.

[0032] In use, the height of the lifting mechanism and the installation of the pressing plate and the pad are adjusted in advance according to the size of the forming mold. The installation method can be referred to the above content. This is a conventional mechanical connection mechanism, which will not be described in detail here. After installation, the forming mold containing coagulated soy milk is first placed in the sliding placement groove 102 of the base 1. Then, external force (such as manpower or mechanical equipment) is applied to push the forming mold to contact the inclined surface. At this time, the precise positioning with the pressing plate is achieved. Then, the pressing plate 7 squeezes the soy milk in the forming mold during the movement of the lifting cylinder 4 driven by the driver 5, squeezing out the water inside and dropping it into the receiving groove 103. Finally, it is discharged from the drain groove 105, thus completing the pressing and shaping process. After pressing, it can be taken out.

[0033] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
