Description
Technical Field
[0001] This utility model relates to the field of soybean product processing technology, specifically a forming device for the production and processing of dried tofu. Background Technology
[0002] Dried tofu is a traditional Chinese soy product, a further processed form of tofu. It is savory, refreshing, firm yet chewy, and keeps well for a long time. It's a popular dish in many Chinese cuisines, and is primarily produced in South China and the Jiangnan region. Dried tofu is rich in nutrients, containing abundant protein, fat, and carbohydrates, as well as various minerals essential for the human body, such as calcium, phosphorus, and iron. Currently, to meet the growing demand for soy products, cylinders are used to compress multiple layers of dried tofu simultaneously to improve compression efficiency.
[0003] For example, an existing Chinese patent (publication number: CN217564846U) discloses a forming device for the production and processing of dried tofu. By activating a cylinder, the output end of the cylinder presses a pressing plate, which in turn presses the raw materials for making dried tofu in the forming frame through the forming plate at the bottom. At the same time, the raw materials for making dried tofu in multiple forming frames can be pressed through a reset mechanism. After pressing, the forming frame and the forming plate can be separated by themselves under the action of the reset mechanism, which makes the sorting speed of dried tofu faster and improves the processing efficiency of dried tofu.
[0004] However, the above-mentioned tofu processing forming device still has some drawbacks in actual use: Although the tofu processing forming device can use a reset mechanism (such as an internal spring structure) to make the forming frame and the forming plate separate on their own, the tofu sorting speed is faster and the tofu processing efficiency is improved, the device has multiple forming frames and forming plates, which results in a correspondingly large number of internal reset mechanisms, which undoubtedly increases the cost of maintenance and makes maintenance more inconvenient.
[0005] To address these issues, we designed a forming device for tofu production and processing. Utility Model Content
[0006] The purpose of this utility model is to provide a forming device for the production and processing of dried tofu, so as to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, this utility model provides a forming device for the production and processing of dried tofu, including a processing frame with a fixed groove on the front side, a threaded screw rotatably installed on one side of the fixed groove in the vertical direction, a nut threaded onto the threaded screw, a motor installed on the top of the processing frame, the drive shaft of the motor being connected to the top end of the threaded screw, an extrusion plate installed on one side of the nut, a guide rod fixedly installed on the other side of the fixed groove in the vertical direction, a forming groove installed on one side of the guide rod, and the extrusion plate engaging with the forming groove.
[0008] Furthermore, there are multiple nuts, and these multiple nuts are equally spaced on the threaded screw. The number of extrusion plates and forming grooves corresponds to the number of nuts.
[0009] Furthermore, a fixing member is fixedly installed on one side of the nut, and the other end of the fixing member is fixedly connected to one side of the extrusion plate. Multiple fixing plates are fixedly sleeved on the guide rod, and one side of the fixing plate is fixedly connected to one side of the forming groove.
[0010] Furthermore, a sliding plate is fixedly installed on the side of the extrusion plate away from the fixing member. The sliding plate has a sliding hole that matches the guide rod. The sliding plate is slidably sleeved on the guide rod through the sliding hole.
[0011] Furthermore, bearings are fixedly installed on both the top and bottom walls of the fixed groove, and the two ends of the threaded rod are respectively fixedly inserted into the inner rings of the two bearings.
[0012] Furthermore, a liquid receiving tank is fixedly installed on the bottom wall of the fixed groove, and the extrusion plate and the forming groove are located above the liquid receiving tank. The length and width of the liquid receiving tank are both greater than the length and width of the extrusion plate and the forming groove.
[0013] Furthermore, a sealing plug is movably inserted into the front side of the liquid receiving tank.
[0014] Compared with the prior art, the beneficial effects of this utility model are: by turning on the motor, the threaded screw can be rotated, which causes the nut to drive the fixing part and the extrusion plate to move downward, and facilitates the pressing of the tofu raw material in the forming groove into shape. When the extrusion plate moves upward, the formed tofu can be easily taken out from the forming groove. The forming device has a simple structure and is easy to operate, which not only reduces the tedious internal maintenance problems, but also improves the processing efficiency.
[0015] Compared with the prior art, the beneficial effects of this utility model are: through the cooperation of the sliding plate and the sliding hole, the sliding plate can be driven to move on the guide rod when the extrusion plate slides, which can limit the side of the extrusion plate away from the nut and avoid the problem of the extrusion plate tilting.
[0016] Compared with the prior art, the beneficial effects of this utility model are: by setting up a liquid receiving tank, the juice overflowing from the molding tank can be easily collected, avoiding the problem of polluting the surrounding environment; by pulling the sealing plug out from the front of the liquid receiving tank, the juice can be easily drained to a designated location for convenient processing.

[0022] 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.
[0023] Please see Figure 1-4 This utility model provides a technical solution: a forming device for the production and processing of dried tofu, including a processing frame 1 with a fixed groove 2 on the front side, a threaded screw 3 rotatably arranged on one side of the fixed groove 2 in the vertical direction, a nut 4 threadedly sleeved on the threaded screw 3, a motor 5 arranged on the top of the processing frame 1, the drive shaft of the motor 5 being connected to the top end of the threaded screw 3, an extrusion plate 6 arranged on one side of the nut 4, a guide rod 7 fixedly installed on the other side of the fixed groove 2 in the vertical direction, a forming groove 8 arranged on one side of the guide rod 7, and the extrusion plate 6 and the forming groove 8 cooperating and abutting against each other;
[0024] A fixing member 9 is fixedly installed on one side of the nut 4, and the other end of the fixing member 9 is fixedly connected to one side of the extrusion plate 6. Multiple fixing plates 10 are fixedly sleeved on the guide rod 7, and one side of the fixing plate 10 is fixedly connected to one side of the forming groove 8.
[0025] In practice, the raw materials for making dried tofu are poured into the forming tank 8, and then the motor 5 is turned on. The drive shaft of the motor 5 drives the threaded screw 3 to rotate, which causes the nut 4 to drive the fixing part 9 and the extrusion plate 6 to move downward, making it easier to press the raw materials for dried tofu in the forming tank 8 into shape. When the extrusion plate 6 moves upward, the formed dried tofu can be easily removed from the forming tank 8. This forming device has a simple structure and is easy to operate. It not only reduces the tedious internal maintenance problems, but also improves the processing efficiency.
[0026] See Figure 1-4 There are multiple nuts 4, which are evenly spaced on the threaded screw 3. The number of extrusion plates 6 and forming grooves 8 corresponds to the number of nuts 4. The arrangement of multiple nuts 4, extrusion plates 6, and forming grooves 8 allows for the simultaneous processing of more tofu raw materials, further improving processing efficiency.
[0027] See Figure 1-4 A slide plate 11 is fixedly installed on the side of the extrusion plate 6 away from the fixing member 9. The slide plate 11 has a sliding hole 12 that matches the guide rod 7. The slide plate 11 is slidably sleeved on the guide rod 7 through the sliding hole 12.
[0028] In specific implementation, based on the above implementation, the sliding of the extrusion plate 6 can drive the slide plate 11 to move along the guide rod 7, which can limit the extrusion plate 6 on the side away from the nut 4, and can avoid the problem of the extrusion plate 6 tilting.
[0029] See Figure 1-4 Bearings 13 are fixedly installed on both the top and bottom walls of the fixed groove 2, and the two ends of the threaded rod 3 are respectively fixedly inserted into the inner rings of the two bearings 13. This facilitates the rotational installation of the threaded rod 3 in the fixed groove 2, ensuring that the threaded rod 3 can rotate normally and avoiding motion interference problems, and also brings convenience to the installers.
[0030] See Figure 1-4 A liquid receiving tank 14 is fixedly installed on the bottom wall of the fixed tank 2. The extrusion plate 6 and the forming tank 8 are located above the liquid receiving tank 14. The length and width of the liquid receiving tank 14 are greater than the length and width of the extrusion plate 6 and the forming tank 8.
[0031] In practice, based on the above implementation, by setting up a liquid receiving tank 14, the juice overflowing from the molding tank 8 can be easily collected, thus avoiding the problem of polluting the surrounding environment.
[0032] See Figure 1-4 A sealing plug 15 is movably inserted into the front side of the liquid receiving tank 14.
[0033] In practice, based on the above implementation, by pulling the sealing plug 15 out from the front of the liquid receiving tank 14, the juice can be easily drained to a designated location for convenient processing.
[0034] It should be noted that, in order to facilitate the insertion and removal of the sealing plug 15 on the liquid receiving tank 14, a drain port that is compatible with the sealing plug 15 can be opened on the front side of the liquid receiving tank 14, and the drain port is connected to the inside of the liquid receiving tank 14, so that the sealing plug 15 can be inserted and removed and positioned by friction.
[0035] Before use, all electrical components involved in the molding device need to be connected to an external power source, or a battery pack should be installed in an area outside the processing frame 1 that does not obstruct other components. Then, the battery pack and electrical components are connected via wiring. It is also necessary to avoid the wiring from becoming tangled due to the movement of the components. Wiring needs to be buried and planned and organized to provide power to the electrical components, thereby ensuring their normal operation and switching. Since connecting the electrical components to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.
[0036] Working principle: When in use, first pour the raw materials for making dried tofu into the forming tank 8, then turn on the motor 5, which will cause the drive shaft of the motor 5 to drive the threaded screw 3 to rotate, so that the nut 4 drives the fixing part 9 and the extrusion plate 6 to move downward, and facilitate the pressing of the raw materials for dried tofu in the forming tank 8 into shape. When the extrusion plate 6 moves upward, the formed dried tofu can be easily removed from the forming tank 8. This forming device has a simple structure and is easy to operate. It not only reduces the tedious internal maintenance problems, but also improves the processing efficiency.
[0037] In addition, during the above operation, the sliding of the extrusion plate 6 can cause the slide plate 11 to move along the guide rod 7, which can limit the extrusion plate 6 away from the nut 4 and prevent the extrusion plate 6 from tilting.
[0038] By setting up the liquid receiving tank 14, the juice overflowing from the molding tank 8 can be easily collected, avoiding the problem of polluting the surrounding environment. By pulling out the sealing plug 15 from the front of the liquid receiving tank 14, the juice can be easily drained to a designated location for easy processing.
