[0002] Dried tofu is a processed product of tofu, savory and refreshing, firm yet chewy, and keeps well for a long time. It 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. Dried tofu is one of the best foods to accompany drinks or meals, and is also convenient to carry and eat while traveling. In the production of dried tofu, the pressed blocks need to be cut into smaller pieces for easier packaging and consumption.

[0003] Existing whole-piece tofu cutting processes use mechanical equipment, commonly employing a cylinder-driven lifting die to cut the whole piece of tofu conveyed below. This cutting process requires a lifting and lowering motion. In the context of large-scale production, this method suffers from poor overall continuity, resulting in low cutting efficiency. Patent documents with authorization announcement numbers CN211164070U, CN201712027U, and CN210389379U all exhibit the aforementioned problems. Summary of the Invention

[0004] This invention provides a tofu-cutting device, which aims to solve the problems of poor continuity and low cutting efficiency of current equipment when cutting tofu.

[0005] This invention is implemented as follows: a tofu-cutting device includes: a first straight segment and a second straight segment arranged vertically, each of which has a built-in cutting mechanism for cutting the tofu into pieces; each of the first and second straight segments includes a U-shaped housing and a conveying mechanism for conveying the tofu within the U-shaped housing; a turning mechanism is provided at the connection between the first and second straight segments, which can guide the tofu to achieve a change in conveying position.

[0008] Preferably, the cutting mechanism includes at least four positioning guide rollers rotatably installed inside the U-shaped housing. The at least four positioning guide rollers are located at the four corners above and below the rear conveyor belt, respectively. Multiple cutting steel wires are sleeved on the at least four positioning guide rollers, and the cutting sections of the multiple cutting steel wires pass between the front conveyor belt and the rear conveyor belt.

[0009] Preferably, a central connecting plate is provided between the front conveyor belt and the rear conveyor belt, and the two sides of the central connecting plate are respectively fixedly connected to the inner walls of the two sides of the U-shaped shell, and the multiple cutting steel wires slide through the central connecting plate.

[0010] Preferably, at least one sliding roller is rotatably mounted on the central connecting plate and the U-shaped housing, and the at least one sliding roller is staggered from the multiple cutting steel wires.

[0014] Compared with related technologies, the tofu cutting equipment provided by this invention has the following advantages:

[0015] Compared with existing technologies, this tofu-cutting equipment, by setting up a vertical first and second straight segment, allows tofu to be cut continuously in two directions. After completing one direction, a turning mechanism is used to switch to the other direction for cutting, achieving a smooth transition in the tofu-carrying position. This not only ensures the continuity of the tofu-cutting process but also avoids problems such as jamming and blockage during the tofu-carrying process, further improving the stability and reliability of the equipment. It basically achieves the goal of continuous operation, with a short dwell time during the transition. Compared with traditional cutting equipment that uses a cylinder-lifting die to cut the whole piece of tofu conveyed below, which requires a lifting process during cutting, this equipment improves cutting efficiency. At the same time, the built-in cutting mechanism can accurately cut the tofu, ensuring that the size and shape of the tofu are consistent, meeting the market's requirements for tofu quality.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0038] This invention provides a tofu-cutting device, such as... Figure 1-19 As shown, the bean curd cutting device includes: a first straight segment 1 and a second straight segment 2 arranged vertically, each of which has a built-in cutting mechanism for cutting the bean curd into pieces; each of the first straight segment 1 and the second straight segment 2 includes a U-shaped housing 3 and a conveying mechanism for conveying the bean curd within the U-shaped housing 3; a turning mechanism is provided at the connection between the first straight segment 1 and the second straight segment 2, which can guide the bean curd to achieve a change in conveying position.

[0039] In this embodiment, the tofu-cutting device, by setting a vertical first straight segment 1 and a second straight segment 2, enables the tofu to be cut continuously in two directions. After completing one direction, a turning mechanism is used to turn to another direction for cutting, achieving a smooth transition in the tofu-carrying position. This not only ensures the continuity of the tofu-cutting process but also avoids problems such as jamming and blockage during the tofu-carrying process, further improving the stability and reliability of the equipment. It basically achieves the goal of continuous operation, with a short dwell time during the transition. Compared with traditional cutting equipment that uses a cylinder-lifting die to cut the whole piece of tofu conveyed below, which requires a lifting process during cutting, this device improves the cutting efficiency. At the same time, the built-in cutting mechanism can accurately cut the tofu, ensuring that the size and shape of the tofu are consistent, meeting the market's requirements for tofu quality.

[0040] In this scheme, the transmission method adopts the transmission mechanism inside the U-shaped shell 3. The first straight segment 1 and the second straight segment 2 have basically the same structure, which is beneficial to the manufacturer's production and manufacturing, and also facilitates on-site assembly, thus reducing production costs.

[0041] In a further preferred embodiment of the present invention, the transmission mechanism includes a front transmission belt 4 and a rear transmission belt 5, both of which are rotatably mounted inside the U-shaped housing 3. The transmission top surfaces of the front transmission belt 4 and the rear transmission belt 5 are located on the same horizontal line. The steering mechanism is connected to the side of the rear transmission belt 5 on the first straight segment 1 and the front end of the front transmission belt 4 on the second straight segment 2.

[0042] In this embodiment, the transmission mechanism includes a front transmission belt 4 and a rear transmission belt 5 rotatably mounted within the U-shaped housing 3. This design enables continuous transmission of the dried bean curd during the cutting process, ensuring smooth cutting. More importantly, the top surfaces of the front and rear transmission belts 4 and 5 are on the same horizontal line, ensuring the stability and consistency of the dried bean curd during transmission and avoiding the problem of positional shift or tilting of the dried bean curd due to inconsistent transmission belt heights. The steering mechanism connects to the side of the rear transmission belt 5 on the first straight segment 1 and the front end of the front transmission belt 4 on the second straight segment 2. This design cleverly enables the dried bean curd to be turned during transmission, ensuring that the dried bean curd can be continuously fed into the cutting mechanism for cutting. Through this design of the transmission and steering mechanisms, this dried bean curd cutting equipment can not only efficiently complete the cutting of dried bean curd in practical applications, but also ensure that the cut dried bean curd is of consistent size and shape, meeting the market's requirements for dried bean curd quality. At the same time, this design also makes the equipment simple in structure, easy to operate, and low in maintenance cost.

[0043] In a further preferred embodiment of the present invention, the discharge port 6 is provided on the discharge side of the U-shaped shell 3, and the discharge port 6 on the first straight segment 1 is correspondingly provided with the turning mechanism. The opening size of the discharge port 6 is larger than the overall size of the cut bean curd pieces.

[0044] In this embodiment, the discharge side of the U-shaped housing 3 is provided with a discharge port 6, and the size of the discharge port 6 is larger than the overall size of the cut tofu pieces (commonly processed in factories). This design ensures that the tofu pieces can be discharged smoothly from the discharge port 6 without getting stuck. In addition, the larger size of the discharge port 6 also helps to reduce the breakage rate of the tofu pieces during discharge, maintaining the integrity of the tofu. The discharge port 6 on the first straight segment 1 is correspondingly set with the turning mechanism. This layout allows the tofu to be discharged smoothly through the discharge port 6 after cutting and turning, improving the continuity and efficiency of the cutting process.

[0045] In a further preferred embodiment of the present invention, the cutting mechanism includes at least four positioning guide rollers 7 rotatably mounted inside the U-shaped housing 3. The at least four positioning guide rollers 7 are respectively located at the four corners above and below the rear conveyor belt 5. Multiple cutting steel wires 8 are sleeved on the at least four positioning guide rollers 7. The cutting sections of the multiple cutting steel wires 8 pass between the front conveyor belt 4 and the rear conveyor belt 5.

[0046] In this embodiment, the cutting mechanism includes at least four positioning guide rollers 7 rotatably mounted inside the U-shaped housing 3. This design fully utilizes the rotation function of the positioning guide rollers 7, enabling the cutting steel wire 8 to move along a preset path, ensuring the stability and accuracy of the bean curd during the cutting process. The at least four positioning guide rollers 7 are located at the four corners above and below the rear conveyor belt 5, respectively. This layout helps to improve the stability during the cutting process and reduce the problem of uneven cutting caused by the positional deviation of the bean curd. The cutting section of the cutting steel wire 8 passes between the front conveyor belt 4 and the rear conveyor belt 5. This design allows the cutting steel wire 8 to make close contact with the bean curd, achieving efficient and precise cutting.

[0047] In a further preferred embodiment of the present invention, a central connecting plate 9 is provided between the front conveyor belt 4 and the rear conveyor belt 5. The two sides of the central connecting plate 9 are respectively fixedly connected to the inner walls of the two sides of the U-shaped shell 3, and the multiple cutting steel wires 8 slide through the central connecting plate 9.

[0048] In this embodiment, a central connecting plate 9 is provided between the front conveyor belt 4 and the rear conveyor belt 5. This design further enhances the stability between the conveyor belts, ensuring the stability and consistency of the dried bean curd during the transmission process. The two sides of the central connecting plate 9 are fixedly connected to the inner walls of the two sides of the U-shaped shell 3, respectively. This fixing method increases the stability of the central connecting plate 9 and reduces displacement or deformation caused by external forces. Multiple cutting steel wires 8 slide through the central connecting plate 9. This design allows the cutting steel wires 8 to move within a stable guide rail, improving the accuracy and stability of the cutting process. This dried bean curd cutting equipment further improves the stability and accuracy of the cutting process, reducing the problem of uneven cutting or damage caused by equipment instability. At the same time, this design also makes the equipment structure more compact and improves the overall efficiency of the equipment.

[0049] In a further preferred embodiment of the present invention, at least one sliding roller 10 is rotatably mounted on the central connecting plate 9 and the U-shaped housing 3, and the at least one sliding roller 10 is staggered from the plurality of cutting steel wires 8.

[0050] In this embodiment, at least one sliding roller 10 is rotatably mounted on the central connecting plate 9 and the U-shaped housing 3. This design enables feeding during the transfer of dried bean curd, avoiding jamming between the two conveyor belts. At the same time, at least one sliding roller 10 is staggered from multiple cutting steel wires 8. This layout avoids conflict between the sliding roller 10 and the cutting steel wires 8, ensuring smooth transfer of dried bean curd during the cutting process.

[0051] In a further preferred embodiment of the present invention, at least four of the positioning guide rollers 7 are evenly provided with multiple positioning grooves for positioning the cutting steel wire 8, and the central connecting plate 9 is evenly provided with multiple positioning holes for positioning the cutting steel wire 8, and the multiple positioning holes and the multiple positioning grooves are correspondingly arranged.

[0052] In this embodiment, at least four positioning guide rollers 7 are evenly provided with multiple positioning grooves for positioning the cutting steel wire 8. This design ensures the stability and accuracy of the cutting steel wire 8 during the cutting process. The positioning grooves limit the movement range of the cutting steel wire 8 and prevent it from deviating or jumping during the cutting process, thereby improving the cutting quality and efficiency. The central connecting plate 9 is evenly provided with multiple positioning holes for positioning the cutting steel wire 8. This design further enhances the positioning effect of the cutting steel wire 8. The corresponding setting of the positioning holes and positioning grooves enables the cutting steel wire 8 to remain stable during the cutting process, ensuring that the cut tofu is of consistent size and shape.

[0053] In a further preferred embodiment of the present invention, the steering mechanism includes a transfer plate 11 fixedly installed in the discharge port 6 on the first straight section 1. The two ends of the transfer plate 11 are respectively connected to the side of the rear conveyor belt 5 on the first straight section 1 and the front end of the front conveyor belt 4 on the second straight section 2. The top surface of the transfer plate 11 is located on the same horizontal line as the top surface of the corresponding front conveyor belt 4 and rear conveyor belt 5.

[0054] In this embodiment, the turning mechanism includes a transfer plate 11 fixedly installed in the discharge port 6 on the first straight section 1. This design cleverly realizes the turning of the bean curd during the transmission process, ensuring that the bean curd can be continuously fed into the cutting mechanism for cutting. The two ends of the transfer plate 11 are respectively connected to the side of the rear conveyor belt 5 on the first straight section 1 and the front end of the front conveyor belt 4 on the second straight section 2. This connection method allows the bean curd to transition smoothly during the transmission process, avoiding positional deviation or jamming caused by turning. The transmission top surface of the transfer plate 11 is on the same horizontal line as the corresponding transmission top surfaces of the front conveyor belt 4 and the rear conveyor belt 5. This design ensures the stability and consistency of the bean curd during the transmission process, avoiding the problem of positional deviation or tilting of the bean curd due to inconsistent transmission height.

[0055] In a further preferred embodiment of the present invention, a transfer conveyor belt 12 is rotatably installed inside the transfer plate 11. The front transfer belt 4, the rear transfer belt 5, the sliding roller 10 and the transfer conveyor belt 12 all rotate clockwise, and the positioning guide roller 7 rotates counterclockwise to drive the cutting steel wire 8 to rotate counterclockwise.

[0056] In this embodiment, a transfer conveyor belt 12 is rotatably installed inside the transfer plate 11. This design increases the stability of the dried bean curd during the transfer process and reduces problems caused by the slippage of the dried bean curd. The front transfer belt 4, the rear transfer belt 5, the sliding roller 10, and the transfer conveyor belt 12 all rotate clockwise to ensure that the transmission direction is consistent. The positioning guide roller 7 rotates counterclockwise to drive the cutting steel wire 8 to rotate counterclockwise, so that the cutting steel wire 8 rotates from top to bottom to cut, which facilitates the subsequent processing of the cutting steel wire 8.

[0057] In another preferred embodiment of the present invention, a pushing mechanism is provided on both the first straight segment 1 and the second straight segment 2. The pushing mechanism includes a U-shaped bracket 13 fixedly installed on the side of the U-shaped housing 3 corresponding to the discharge port 6. The U-shaped bracket 13 located on the first straight segment 1 is fixedly connected to the second straight segment 2. A rectangular guide rod 14 is fixedly installed on the U-shaped housing 3 and the U-shaped bracket 13. The rectangular guide rod 14 passes through the discharge port 6. The corresponding rectangular guide rod 14 is located above the transfer plate 11. A transmission plate 15 is slidably sleeved on the rectangular guide rod 14. The bottom of the transmission plate 15... A pusher plate 16 for pushing dried bean curd is fixedly installed on the part. The pusher plate 16 can push the material to slide above the corresponding front conveyor belt 4 or push it out of the U-shaped housing 3. The bottom of the pusher plate 16 is slightly higher than the upper surface of the transfer plate 11. The width of the transmission plate 15 and the pusher plate 16 is smaller than the width of the discharge port 6. The same pusher screw 17 is rotatably installed on the U-shaped housing 3 and the U-shaped bracket 13. The pusher screw 17 is threaded through the transmission plate 15. A motor 18 is fixedly installed on the side of the U-shaped housing 3. The output shaft of the motor 18 is fixedly connected to one end of the pusher screw 17.

[0058] In the above embodiment, the use of the pushing mechanism pushes the cut bean curd above the corresponding front conveyor belt 4 or pushes it out of the U-shaped housing 3, completing the turning and feeding of the bean curd and the discharge of the cut bean curd. People only need to place a receiving frame at the discharge port 6 of the second straight section 2 to receive the material. At the same time, the pushing mechanism between the first straight section 1 and the second straight section 2 connects the two U-shaped housings 3, increasing the stability of the equipment. The bottom of the pushing plate 16 is slightly higher than the upper surface of the transfer plate 11. This design can reduce friction with the conveyor belt and also ensure the smoothness of pushing.

[0059] In another preferred embodiment of the present invention, a hot knife mechanism is provided on both the first straight segment 1 and the second straight segment 2. The hot knife mechanism includes a heating shell 19 fixedly installed in the U-shaped shell 3. The heating shell 19 is located above the front conveyor belt 4. Through holes for the cutting steel wire 8 to pass through are opened on both sides of the heating shell 19. An electric heating component 20 is fixedly installed in the heating shell 19.

[0060] In the above embodiment, a hot knife mechanism is provided on both the first straight segment 1 and the second straight segment 2. This design can provide high-temperature heat, and the heated cutting steel wire 8 has a better cutting effect during the cutting process, further improving the quality of the cut bean curd. The heating temperature of the cutting steel wire 8 is maintained at 80-90℃. An electric heating component 20 (using an electric heating wire) is fixedly installed inside the heating shell 19. This design provides a stable heat source through the electric heating component 20, ensuring the heat requirements of the cutting steel wire 8 during the cutting process and improving the cutting effect and quality.

[0061] In another preferred embodiment of the present invention, a transverse material-arranging mechanism is provided on both the first straight segment 1 and the second straight segment 2. The transverse material-arranging mechanism includes a transverse screw 21 rotatably mounted on the bottom of the heating housing 19 using a bearing seat. A second motor 22 is fixedly mounted on the bottom of the heating housing 19. The output shaft of the second motor 22 is fixedly connected to one end of the transverse screw 21. A cutting plate 23 is threadedly sleeved on the transverse screw 21. The upper surface of the cutting plate 23 slides in contact with the bottom of the heating housing 19. The cutting plate 23 can slide to one side of the pusher plate 16 or be offset from the pusher plate 16. The cutting plate 23 is located above the front conveyor belt 4.

[0062] In the above embodiment, during the cutting process of dried bean curd, before pushing the material, the position of the cutting plate 23 is adjusted according to the spacing of each batch of dried bean curd to ensure that the cut dried bean curd is aligned, which facilitates the next processing and centralized discharge. During adjustment, the motor 22 can be started to drive the transverse screw 21 to rotate, driving the cutting plate 23 to slide to the designated position. When it is necessary to push the dried bean curd, after ensuring that the dried bean curd is neat, the motor 22 drives the cutting plate 23 to reset to the position of the offset pushing plate 16 to avoid affecting the normal pushing of the pushing plate 16 and the intermittent movement of the equipment.

[0063] In another preferred embodiment of the present invention, a lifting and balancing mechanism is provided on the second straight segment 2. The lifting and balancing mechanism is correspondingly arranged with the front conveyor belt 4. The lifting and balancing mechanism includes a U-shaped assembly frame 24 fixedly installed on the U-shaped housing 3. An electric telescopic rod 25 is fixedly installed on the U-shaped assembly frame 24. A cutting plate 26 is fixedly installed on the output rod of the electric telescopic rod 25. The cutting plate 26 is the same width as the front conveyor belt 4 below.

[0064] In the above embodiment, when the first-cut bean curd is fed into the front conveyor belt 4 through the transfer plate 11 and the pushing mechanism, the second cutting plate 26 is located at the lowest position but does not contact the upper surface of the front conveyor belt 4. This allows the first-cut bean curd to be aligned, facilitating secondary cutting. After the arrangement is completed, the electric telescopic rod 25 resets the second cutting plate 26 to avoid affecting the normal transmission of materials. The electric telescopic rod 25 has a fast lifting speed and a rapid response.

[0065] In another preferred embodiment of the present invention, a blade washing mechanism is provided in both the first straight segment 1 and the second straight segment 2. The blade washing mechanism includes a cleaning tank 27 fixedly installed at the bottom of the U-shaped housing 3. Multiple tensioning rollers 28 are rotatably installed in the U-shaped housing 3. The multiple tensioning rollers 28 tension the cutting steel wire 8 into the solution in the cleaning tank 27. An impeller shaft 29 is rotatably installed in the U-shaped housing 3, penetrating the cleaning tank 27. The impeller shaft 29 is located below the cutting steel wire 8.

[0066] In the above embodiment, during use, the cutting steel wire 8 after cutting the dried bean curd passes through the cleaning tank 27, which is filled with cleaning water. During use, the impeller shaft 29 rotates, which can agitate the water and thus rinse the cutting steel wire 8, preventing residue from remaining on the cutting steel wire 8, ensuring cleanliness, and effectively preventing it from being affected during subsequent heating.

[0067] In another preferred embodiment of the present invention, the transmission method of this solution is as follows: a motor 30 is fixedly installed on one side of any of the U-shaped housings 3. The output shaft of the motor 30 is fixedly connected to any input end of the front conveyor belt 4 or the rear conveyor belt 5. Sprockets 31 are fixedly sleeved on the adjacent input ends of the front conveyor belt 4 and the rear conveyor belt 5 on the first straight segment 1 and the second straight segment 2 and on the sliding roller 10. The same chain 32 is sleeved on multiple sprockets 31. A power conversion shaft 33 is rotatably installed on one side of the chain 32 on the U-shaped housing 3. A power gear 34 is fixedly sleeved on any input end of the front conveyor belt 4 or the rear conveyor belt 5. A differential gear 35 that meshes with the power gear 34 is fixedly sleeved on the power conversion shaft 33. The differential ratio between the power gear 34 and the differential gear 35 is 1:3 to 5. A positioning guide roller 7 is fixedly sleeved on the impeller shaft 29 and the power conversion shaft 33. There is a second sprocket 36, and a chain 37 is fitted onto multiple sprockets 36. A power conversion shaft 38 is rotatably mounted on the U-shaped housing 3 corresponding to the second straight segment 2. An extension shaft 39 is fixedly mounted on the input end of the front transmission belt 4 corresponding to the power conversion shaft 38. Both the power conversion shaft 38 and the extension shaft 39 are fixedly fitted with bevel gears 40, and two bevel gears 40 mesh with each other. A circular gear 41 is fixedly fitted onto the extension shaft 39. A second spur gear 42 is fixedly fitted onto the input end of the front conveyor belt 4. The first spur gear 41 and the second spur gear 42 mesh with each other. The differential speed ratio between the first spur gear 41 and the second spur gear 42 is 1:1. A gear groove 43 is provided on the input end of the front conveyor belt 4 corresponding to the second spur gear 42. A synchronous gear 44 is fixedly fitted onto one input end of the transfer conveyor belt 12. The same chain 45 is fitted onto the gear groove 43 and the synchronous gear 44.

[0068] In the above embodiment, during transmission, the motor 30 is energized, driving the corresponding front conveyor belt 4 or rear conveyor belt 5 to rotate clockwise. The front conveyor belt 4 and rear conveyor belt 5 are driven by sprocket 31 and chain 32 to drive the sliding roller 10 to rotate clockwise synchronously. At this time, the power gear 34 rotates clockwise synchronously, driving the meshing differential gear 35 and power conversion shaft 33 to rotate counterclockwise. The counterclockwise rotation of the power conversion shaft 33 is achieved by sprocket 36 and chain 37, causing the impeller shaft 29 to rotate and spray water. Simultaneously, the cutting steel wire 8 rotates counterclockwise, sliding from top to bottom along the cleaning tank 27 towards the heating shell 19. At the same time, the front conveyor belt 4 drives the extension shaft 39 and... The corresponding bevel gear 40 rotates clockwise, while another bevel gear 40 rotates counterclockwise, driving the second power conversion shaft 38 to rotate counterclockwise. The second power conversion shaft 38 drives the first spherical gear 41 to rotate counterclockwise, and the first spherical gear 41 drives the meshing second spherical gear 42 to rotate clockwise. At the same time, the third chain 45 drives the transfer conveyor belt 12 to rotate clockwise, realizing the integrated operation of transmission, feeding, and cutting. It has a unified power input, good stability, tight overall connection, and reasonable differential speed ratio settings. The first straight segment 1 and the second straight segment 2 have the same power connection structure in the front conveyor belt 4, the rear conveyor belt 5, the cutting steel wire 8, the sliding roller 10, and the impeller shaft 29, ensuring the normal operation of the equipment as a whole.

[0069] In summary, compared with related technologies, this tofu-cutting equipment, by setting up a vertical first straight segment 1 and a second straight segment 2, enables continuous cutting of tofu in two directions. After completing one direction, a turning mechanism is used to switch to the other direction for cutting, achieving smooth switching of the tofu-cutting position. This not only ensures the continuity of the tofu-cutting process but also avoids problems such as jamming and blockage during the tofu-cutting process, further improving the stability and reliability of the equipment. It basically achieves the goal of continuous operation, with a short dwell time during switching. Compared with traditional cutting equipment that uses a cylinder-lifting die to cut the whole piece of tofu conveyed below, which requires a lifting process during cutting, this equipment improves cutting efficiency. At the same time, the built-in cutting mechanism can accurately cut the tofu, ensuring that the size and shape of the tofu are consistent, meeting the market's requirements for tofu quality.
