Description

Technical Field

[0001] This utility model relates to the technical field of soybean product making equipment, and more specifically, to a switching device for making tofu and soy pudding. Background Technology

[0002] Among soy products, tofu and tofu pudding are popular traditional products, and their production processes have always attracted much attention. In current tofu and tofu pudding production processes, different steps require the use of multiple containers, and soy milk or intermediate products need to be transferred back and forth between these containers. For example, when making tofu pudding, the soy milk needs to be transferred to a specific container to add a coagulant for coagulation; while when making tofu, the coagulated tofu pudding needs to be transferred to another container with a filtration function for pressing and dehydration. This multi-container, multi-transfer production method has many drawbacks. On the one hand, it increases the complexity and difficulty of the production process, consuming a significant amount of time and labor costs; on the other hand, the multiple transfers easily cause spillage of soy milk or tofu pudding, leading to waste of raw materials and increasing the risk of product contamination, affecting product quality and hygiene safety.

[0003] Therefore, in order to solve the above-mentioned problems in the existing tofu and tofu pudding production process, this utility model proposes a tofu and tofu pudding production switching device, which aims to simplify the production process and improve production efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to provide a device for switching between making tofu and douhua, which can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides a switching device for making tofu and soy pudding, comprising: a switching drive unit; the switching drive unit is a contact drive structure or a non-contact drive structure, used to drive a soy product tray to move from the soy pudding making station inside the container body to the tofu making station inside the container body; the soy pudding making station is located between the tofu making station and the top cover sealed to the top of the container body; when the soy product tray is sealed and installed at the soy pudding making station, a sealed chamber for making soy pudding or soy milk is formed between the soy product tray, the container body and the top cover; when the soy product tray moves to the tofu making station, the water filter holes on the side wall of the container body are located between the soy product tray and the top cover, or a water filter gap is formed between the container body and the soy product tray.

[0006] Optionally, the contact drive structure includes one of the following: a lead screw and nut drive mechanism, a gear and rack drive mechanism, or a linkage drive mechanism.

[0007] Optionally, the lead screw and nut drive mechanism includes: a drive motor mounted on the outer wall of the container body, the output end of the drive motor being connected to a lead screw rotatably mounted on the outer wall of the container body, the lead screw being connected to a drive bracket that is slidably fitted in the middle of the displacement slide rail on the side wall of the container body, and the drive bracket being connected to the end of the bean product tray away from the top cover.

[0008] Optionally, the non-contact drive structure includes: a pneumatic drive mechanism or an electromagnet drive mechanism.

[0009] Optionally, the pneumatic drive mechanism includes: a pressure gas inlet disposed on the side wall of the container body, the pressure gas inlet being connected to an air compressor or air pump; the pressure gas inlet is located between the top cover and the tofu making station.

[0010] Optionally, the container body is provided with a limiting and locking structure; when the bean product tray is sealed and installed at the bean curd making station to make bean curd, the limiting and locking structure is controlled to engage with the bean product tray to fix the bean product tray and the container body relatively; when the bean product tray moves from the bean curd making station to the tofu making station, the limiting and locking structure is controlled to disengage from the bean product tray.

[0011] Optionally, the limiting locking structure includes: a limiting locking rod movably connected to the side of the container body, the inner end of the limiting locking rod being inserted into a locking slot on the side of the bean product tray or being engaged on the side of the bean product tray away from the top cover.

[0014] Optionally, two locking structures are provided, which are arranged opposite to each other on both sides of the container body.

[0015] This utility model has the following beneficial effects: This utility model discloses a switching device for making tofu and soy pudding, effectively solving the problem of requiring multiple containers and repeated transfers in existing technologies. It only requires inputting soy milk into the main container body, greatly simplifying the production process, reducing operational difficulty and labor costs, while also reducing the risk of raw material spillage and product contamination, thus improving product quality and hygiene safety. The switching drive unit in the device can adopt a contact or non-contact drive structure, flexibly driving the soy product tray to move from the soy pudding production station to the tofu production station within the main container body. When the soy product tray is sealed and installed at the soy pudding production station, it forms a sealed chamber with the main container body and the top cover, facilitating the production of either soy pudding or soy milk. When the soy product tray moves to the tofu production station, the water-filtering holes or gaps on the side wall of the main container body allow water to be removed, facilitating tofu production. The non-contact drive structure includes a pneumatic drive mechanism, which uses a pressurized gas inlet on the side wall of the main container body connected to an air compressor or pump, with the pressurized gas inlet located between the top cover and the soy pudding production station. When gas is injected into the container body through the pressurized gas inlet, the bean product tray can be smoothly and effectively lowered from the bean curd making station to the tofu making station. Using this driving method reduces the number of structural components in the tofu and bean curd making equipment, lowers the cost, and makes it easy to operate. It also reduces mechanical wear and failure rate, and improves the stability and reliability of the device.

[0020] 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.

[0021] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.

[0023] Example 1: As Figures 1-5 As shown, a tofu and soy pudding production switching device includes: a switching drive unit; the switching drive unit is a contact drive structure or a non-contact drive structure, used to drive the soy product tray 1 to move from the soy pudding production station in the container body 2 to the tofu production station in the container body 2; the soy pudding production station is set between the tofu production station and the top cover 3 sealed to the top of the container body 2; when the soy product tray 1 is sealed and installed in the soy pudding production station, a sealed chamber for making soy pudding or soy milk is formed between the soy product tray 1, the container body 2 and the top cover 3; when the soy product tray 1 moves to the tofu production station, the water filter holes on the side wall of the container body 2 are located between the soy product tray 1 and the top cover 3, or a water filter gap is formed between the container body 2 and the soy product tray 1.

[0024] The working principle and technical effects of the above scheme are as follows: This utility model discloses a tofu and douhua (tofu pudding) production switching device, which is installed inside a tofu machine and can change the tofu machine from douhua processing mode to tofu processing mode. When making tofu pudding, the tofu product tray 1 is sealed and installed at the tofu pudding making station. Since the tofu pudding making station is located between the tofu making station and the top cover 3, which is sealed to the top of the container body 2, a sealed chamber is formed between the tofu product tray 1, the container body 2, and the top cover 3. The operator only needs to pour soy milk into the container body 2 and add coagulants and other materials within this sealed chamber to carry out the tofu pudding making process.

[0025] When the production process needs to be changed from making tofu pudding to making tofu, the switching drive unit comes into play. This switching drive unit can be a contact drive structure or a non-contact drive structure, driving the bean curd tray 1 from the tofu making station within the container body 2 to the tofu making station within the container body 2. When the bean curd tray 1 moves to the tofu making station, the drainage holes on the side wall of the container body 2 are located between the bean curd tray 1 and the top cover 3, or a drainage gap is formed between the container body 2 and the bean curd tray 1. Subsequently, as pressure is continuously applied into the container body 2, the water in the tofu pudding gradually escapes through the drainage holes or drainage gap, thus forming tofu.

[0026] This utility model provides a switching device for making tofu and bean curd, which has the following significant technical advantages compared to the prior art: 1. Simplified production process: In the existing technology, the production of tofu and soy pudding requires multiple containers and transfer between containers. However, this utility model only requires the soy milk to be poured into the container body 2. By utilizing the positional changes of the soy product tray 1 at different work stations and the different structures formed with the container body 2 and the top cover 3, the production of soy pudding and tofu can be completed, which greatly simplifies the production process and reduces the number of operation steps and time costs.

[0027] 2. Improved product quality and hygiene: Reducing the transfer of soy milk or intermediate products between multiple containers lowers the possibility of spillage and avoids waste of raw materials. It also reduces the product's contact with the external environment, lowering the risk of contamination, thereby improving product quality and hygiene.

[0028] 3. Flexible Drive and Precise Control: The switching drive unit adopts either a contact or non-contact drive structure, allowing for flexible selection of the drive method according to actual needs. Non-contact drive structures, such as pneumatic drive mechanisms, inject pressurized gas into the container body 2 through a pressurized gas inlet, causing the bean product tray 1 to fall smoothly. This avoids the mechanical wear and malfunctions that may occur with contact drives, improving the stability and reliability of the device.

[0029] 4. Function Switching: By moving the bean product tray 1 between the tofu making station and the tofu making station, the machine achieves the function of switching between tofu and tofu making. A sealed chamber is formed at the tofu making station for making tofu or soy milk, while the tofu making station uses filter holes or gaps to remove water and make tofu. This allows a single tofu machine to produce multiple bean products, improving the practicality and versatility of the device.

[0030] Example 2: As Figures 1-5 As shown, the contact drive structure includes one of the following: a lead screw and nut drive mechanism 4, a gear and rack drive mechanism, or a linkage drive mechanism. The lead screw and nut drive mechanism 4 includes: a drive motor 401 mounted on the outer wall of the container body 2; the output end of the drive motor 401 is connected to a lead screw 402 rotatably mounted on the outer wall of the container body 2; the lead screw 402 is connected to a drive bracket 403 that slides in the middle within a displacement slide rail on the side wall of the container body 2; and the drive bracket 403 is connected to the end of the bean product tray 1 away from the top cover 3.

[0031] The working principle and technical effects of the above scheme are as follows: When it is necessary to move the bean curd tray 1 from the bean curd making station to the tofu making station within the container body 2, the drive motor 401 mounted on the outer wall of the container body 2 is activated. The output end of the drive motor 401 drives the lead screw 402, which is rotatably mounted on the outer wall of the container body 2, to start rotating. Since the lead screw 402 is connected to the drive bracket 403, which is slidably fitted in the middle of the displacement slide on the side wall of the container body 2, the rotation of the lead screw 402 will convert the rotational motion into linear motion of the drive bracket 403 within the displacement slide. The drive bracket 403 is connected to the end of the bean curd tray 1 away from the top cover 3, and the linear motion of the drive bracket 403 will drive the bean curd tray 1 to move from the bean curd making station to the tofu making station within the container body 2.

[0032] The lead screw and nut drive mechanism 4 has the following technical effects in the tofu making mode switching: 1. Precise Position Control: The structural characteristics of the lead screw and nut drive mechanism 4 enable it to achieve relatively precise position control. By precisely controlling the number of rotations and angle of the lead screw 402 through the drive motor 401, the displacement of the drive bracket 403 can be precisely controlled, thereby accurately moving the bean curd tray 1 to the designated tofu-making station. This is crucial for the effectiveness of water removal during the tofu-making process, ensuring that the filter holes or gaps are in optimal working condition, and ensuring that the water in the bean curd can be removed stably and evenly, thus improving the quality of the tofu.

[0033] 2. High Stability: The drive bracket 403 slides within a displacement track on the side wall of the container body 2, providing excellent guidance and support for its movement. This design effectively reduces swaying and offset during the movement of the bean product tray 1, ensuring stability throughout the entire drive process. Compared to other drive methods, the screw-nut drive mechanism 4 can better withstand loads, ensuring the reliability of the device during long-term use and reducing the risk of failure due to drive instability.

[0034] 3. Good compatibility with the overall device: The screw nut drive mechanism 4 is compatible with the structural design of the entire tofu and bean curd making switching device. It is mainly installed on the outer wall of the container body 2, without occupying the internal space of the container body 2, and will not interfere with the processes of soy milk input, bean curd making, and water removal. At the same time, it can effectively drive the movement of the soy product tray 1 within the container body 2, realizing the functional switching between tofu and bean curd making.

[0035] Example 3: As Figures 1-5 As shown, the non-contact drive structure includes a pneumatic drive mechanism 5 or an electromagnet drive mechanism. The pneumatic drive mechanism 5 includes a pressurized gas inlet located on the side wall of the container body 2, which is connected to an air compressor or air pump; the pressurized gas inlet is located between the upper cover 3 and the tofu making station.

[0036] The working principle and technical effects of the above scheme are as follows: When the bean curd tray 1 needs to be moved from the bean curd making station to the tofu making station within the container body 2, an air compressor or air pump connected to the pressurized gas inlet starts working. Since the pressurized gas inlet is located on the side wall of the container body 2, between the top cover 3 and the bean curd making station, pressurized gas generated by the air compressor or air pump is injected into the container body 2 through the pressurized gas inlet. As gas is continuously injected, the air pressure above the bean curd tray 1 within the container body 2 gradually increases, creating a pressure difference. Under the action of this pressure difference, the bean curd tray 1 experiences downward pressure, causing it to fall from the bean curd making station to the tofu making station within the container body 2.

[0037] The pneumatic drive mechanism 5 has the following technical effects in the switching of the tofu making mode: 1. The pneumatic drive mechanism 5 adopts a non-contact drive method. Compared with contact drive structures (such as the lead screw and nut drive mechanism 4), there is no direct contact or friction between mechanical parts. During the movement of the bean product tray 1, the parts will not wear due to long-term friction, reducing the probability of mechanical failure. For example, components such as the lead screw 402 and drive bracket 403 in the lead screw and nut drive mechanism 4 may wear during frequent movement, but the pneumatic drive mechanism 5 does not have this problem, improving the stability and reliability of the device and extending its service life.

[0038] 2. The pneumatic drive mechanism 5 has a relatively simple structure, mainly consisting of a pressurized gas inlet, connecting pipelines, and an air compressor or air pump. This simple structure makes the installation and commissioning of the device more convenient and reduces manufacturing costs. Furthermore, routine maintenance only requires checking for blockages in the pressurized gas inlet, leaks in the connecting pipelines, and the operating status of the air compressor or air pump, resulting in low maintenance difficulty and cost.

[0039] 3. The pressurized gas inlet is not only for injecting gas, but can also be used as a coagulation port or a soy milk addition port, enhancing the functionality and practicality of the device. This reduces the number of additional dedicated inlets, simplifies the device's structure, and lowers manufacturing costs. Furthermore, the multi-functional use of the same inlet makes operation more convenient, reducing the number of steps operators need to switch between different inlets, improving production efficiency, and further optimizing the entire tofu and bean curd production process.

[0040] Example 4: Figures 1-5 As shown, the container body 2 is provided with a limiting locking structure 6. When the bean curd tray 1 is sealed and installed at the bean curd making station to make bean curd, the limiting locking structure 6 is engaged with the bean curd tray 1 to fix the bean curd tray 1 to the container body 2. When the bean curd tray 1 moves from the bean curd making station to the tofu making station, the limiting locking structure 6 is disengaged from the bean curd tray 1. There are two limiting locking structures 6, which are arranged opposite to each other on both sides of the container body 2. The limiting locking structure 6 includes: a limiting locking rod movably connected to the side of the container body 2, the inner end of which is inserted into a locking slot on the side of the bean curd tray 1 or engaged on the side of the bean curd tray 1 away from the top cover 3. The limiting locking rod is a screw structure threaded to the side of the container body 2 or a smooth shaft structure slidingly fitted to the side of the container body 2. A rubber anti-slip sleeve is glued to one end of the limiting locking rod that is inserted into the locking slot. When making soy milk or tofu pudding, the locking structure 6 is engaged with the soy product tray 1 to fix the soy product tray 1 to the container body 2, effectively ensuring the stability of the position of the soy product tray 1 during the making of soy milk and tofu pudding.

[0041] The working principle and technical effects of the above scheme are as follows: When the bean curd tray 1 is sealed and installed at the tofu pudding preparation station, ready for tofu pudding production, the operator controls the locking structure 6. Since there are two locking structures 6, positioned opposite each other on both sides of the container body 2, the locking rods on both sides function simultaneously. If the locking rod is a threaded screw structure connected to the side of the container body 2, the operator rotates the screw to move its inner end into the container body 2 until it inserts into the locking slot on the side of the bean curd tray 1 or locks onto the side of the bean curd tray 1 away from the top cover 3. If the locking rod is a sliding shaft structure slidably fitted to the side of the container body 2, the operator pushes the shaft to achieve the same insertion or locking action. At this time, the locking structure 6 fixes the bean curd tray 1 relative to the container body 2, ensuring that the bean curd tray 1 will not shift during the process of converting soy milk into tofu pudding.

[0042] When it is necessary to move the bean curd tray 1 from the tofu making station to the tofu making station, the operator reverses the operation of the locking structure 6. For threaded screw structures, the screw is rotated in the opposite direction, causing its inner end to disengage from the locking slot or the side of the bean curd tray 1; for sliding shaft structures, the shaft is pulled to disengage its inner end from the corresponding position. At this time, the locking structure 6 disengages from the bean curd tray 1, and the bean curd tray 1 can move smoothly to the tofu making station under the drive of the switching drive unit (such as a contact-type screw and nut drive mechanism 4 or a non-contact pneumatic drive mechanism 5).

[0043] The locking structure 6 has the following technical effects: 1. Ensuring Stability in the Production Process: During the production of soy milk or tofu pudding, the locking structure 6 secures the soy product tray 1, effectively ensuring its positional stability. During tofu pudding production, the stable soy product tray 1 ensures the airtightness of the sealed chamber formed between the tray 1, the container body 2, and the lid 3, providing a stable environment for tofu pudding production and preventing problems such as incomplete sealing and air leakage caused by tray movement, thereby improving the quality of the tofu pudding.

[0044] 2. Achieve precise workstation switching: The locking structure 6 can accurately lock and unlock the bean product tray 1 when needed. During workstation switching, it can promptly disengage from the bean product tray 1 without obstructing its movement, ensuring that the switching drive unit can smoothly drive the bean product tray 1 from the tofu making workstation to the tofu making workstation, realizing the functional switching between tofu and tofu making, and the entire switching process is precise and controllable.

[0045] 3. Reasonable and reliable structural design: Two locking structures 6 are provided and are positioned opposite each other on both sides of the container body 2. This symmetrical arrangement makes the fixation of the bean product tray 1 more balanced and stable, avoiding tilting or shaking of the tray due to uneven force on one side. Meanwhile, the locking rod adopts a threaded screw structure or a sliding shaft structure, which is simple in structure and easy to operate and maintain. Furthermore, the end of the locking rod inserted into the locking slot is glued with a rubber anti-slip sleeve, increasing friction and further improving the reliability of the lock, preventing the locking rod from loosening due to vibration or other factors during the manufacturing process.

[0046] 4. Enhanced overall practicality of the device: The design of the limiting locking structure 6 is compatible with the structure and function of the entire tofu and douhua production switching device. It ensures the stability during douhua production without affecting the switching of workstations during tofu production. This allows the device to operate stably and efficiently at different production stages, enhancing the overall practicality and reliability of the device and providing users with a better user experience.
