Description

Technical Field

[0001] This utility model relates to the field of soybean food processing technology, specifically a continuous cutting device for tofu with a coating. Background Technology

[0002] Tofu is a nutritious food with a long history. The public's love for tofu has driven the advancement and development of tofu production technology. The main production process of tofu is twofold: first, making soy milk from soybeans; and second, coagulation, in which the soy milk coagulates into a gel containing a large amount of water under the combined action of heat and a coagulant, which is tofu. When making fermented tofu, a tofu cutting machine is needed to cut the tofu into small pieces of the same size to make fermented tofu.

[0003] In existing tofu processing, tofu is usually cut into blocks by placing it in a tofu cutting mold and then pressing it down with the upper mold. This method requires workers to manually operate the equipment repeatedly, resulting in low work efficiency and increased labor intensity. To improve cutting efficiency, automatic cutting machines are also used to automatically cut tofu into blocks.

[0004] For example, a tofu cutting device disclosed in patent application number "CN202223356826.0" uses a conveyor belt to automatically transport tofu, and an up-and-down cutting mechanism above the conveyor belt can achieve automatic cutting. However, in actual operation, when the tofu is transported to the cutting mechanism, the conveyor belt needs to be stopped, and the cutting mechanism can be lowered before cutting can be achieved. This method cannot maintain the continuous operation of the conveying mechanism, and frequent start-stop is required, which can easily damage the conveying device.

[0005] For example, a tofu cutting machine disclosed in patent application number "CN202321608159.2" uses a conveyor belt to automatically transport tofu. Combined with a rotatable disc cutter above the conveyor belt and a liftable cutter, it can achieve automatic cutting and continuous cutting. However, in the actual cutting process, because the disc cutter is rotating, tofu fragments are easily spread outward during cutting, affecting the cutting environment. Furthermore, the disc cutter is not easy to adjust the distance between the two cutters, making it difficult to adjust the size of the cut pieces. Utility Model Content

[0006] Therefore, in order to overcome any of the above-mentioned shortcomings, this utility model provides a continuous cutting device for tofu with a coating. This cutting device uses a conveying mechanism to transport a carrier. Combined with the first and second cutters above the conveying mechanism, the tofu in the carrier can be automatically cut. At the same time, by opening a groove on the carrier, the first cutter can pass through the groove to cut the tofu in the carrier, thereby realizing continuous cutting. This avoids the problem of damage caused by frequent start and stop of the conveying mechanism, and also avoids the problems of bean curd splattering and inconvenient spacing adjustment caused by the rotation of the disc cutter.

[0007] This utility model is implemented as follows: a continuous cutting device for tofu with a coating, including a carrier for holding tofu and placing it on a conveying mechanism for linear conveying; The mounting frame is located above the conveying mechanism and has a first cutter and a second cutter movably mounted at both ends. The cutting direction of the first cutter is adapted to the conveying direction of the conveying mechanism. The second cutter is set perpendicular to the first cutter and is reciprocated by a linear telescopic device. The carrier has a cutting groove, and the first cutter corresponds to the cutting groove of the carrier and is fixed on the mounting frame.

[0008] Preferably, the conveying mechanism includes a frame and a chain conveyor belt disposed within the frame. The chain conveyor belt is tensioned on tension rollers at the same height on the inner side of the frame and is driven by the rotation of the tension rollers. Guide plates are also provided at both ends of the chain conveyor belt. The guide plates are mounted on the supports of the frame by support rods and the distance between the two guide plates is adjustable. A water receiving trough plate is also fixed below the chain conveyor belt.

[0009] Preferably, the chain plate of the chain conveyor belt is further provided with protrusions, and the carrier is placed on the chain conveyor belt and locked between adjacent protrusions.

[0010] Preferably, the top of the vehicle is provided with a receiving groove, and a handle is provided at the top of the vehicle. The knife grooves are evenly spaced on the top of the vehicle and penetrate through the side wall of the vehicle.

[0011] Preferably, a strip-shaped hole is provided at the top of one end of the mounting frame. The length direction of the strip-shaped hole is perpendicular to the conveying direction of the conveying mechanism. A connecting rod passing through the strip-shaped hole is provided at the top of the first cutter. The first cutter is movably connected to the mounting frame by fasteners screwed onto the connecting rod. A limiting block that contacts the end of the mounting frame is also provided at the top outer end of the first cutter. A cutting part is provided at the bottom of the first cutter. The cutting part has a rounded corner at the end corresponding to the conveying direction of the conveying mechanism.

[0012] Preferably, a linear telescopic device is provided on the top of the other end of the mounting frame. The telescopic end of the linear telescopic device is inserted into the mounting frame. A blade holder is fixed on the telescopic end of the linear telescopic device. A guide post is provided on the top of the blade holder, which passes through the top of the mounting frame to maintain linear movement. A connecting rod is provided on the outer surface of the blade holder. The second cutter is sleeved on the connecting rod of the blade holder through a connecting hole and fixed with fasteners. A vision sensing device is also provided at the bottom of the blade holder. The vision sensing device is electrically connected to the linear telescopic device.

[0013] Compared with the prior art, the present invention has the following advantages: 1. This slitting device continuously conveys the carrier through the conveying mechanism. By combining the knife grooves on the carrier with the cutters on the conveying mechanism, continuous slitting can be achieved. This avoids component wear and fatigue damage caused by frequent start-stop of the conveying mechanism, reduces the probability of equipment failure, and extends the service life of the whole machine.

[0014] 2. Compared with the traditional rotary cutting device, this cutting device uses fixed-position first and second cutters in conjunction with carrier blade grooves for cutting, which can avoid the problem of soybean residue splashing, keep the production environment clean, reduce raw material loss during the tofu cutting process, ensure the integrity of the tofu block shape, improve product quality, and make it easy to adjust the spacing between the cutters to adapt to the cutting needs of tofu blocks of different sizes.

[0015] 3. This cutting device can achieve uninterrupted batch cutting of tofu, significantly improving the cutting efficiency per unit time, meeting the needs of large-scale production scenarios, and enhancing the practicality and market competitiveness of the equipment.

[0019] As described in the background section, existing tofu cutting devices cannot achieve continuous tofu cutting and, during the cutting process, easily cause soybean residue to splatter outwards, making it difficult to adjust the blade spacing.

[0020] For the reasons stated above, please refer to the appendix for solutions to these problems. Figure 1 ~Appendix Figure 3 This utility model provides a continuous cutting device for tofu with a coating, including a carrier 6 for holding tofu and placing it on a conveying mechanism for linear conveying; Mounting frame 7 is set above the conveying mechanism and has a first cutter 8 and a second cutter 10 movably mounted at both ends.

The second cutter 10 is set perpendicular to the first cutter 8 and is reciprocated by a linear telescopic device 9. The carrier 6 has a cutting groove, and the first cutter 8 corresponds to the cutting groove of the carrier 6 and is fixed on the mounting frame 7.

[0021] In this embodiment, the conveying mechanism includes a frame 1 and a chain conveyor belt 2 disposed within the frame 1. The chain conveyor belt 2 is tensioned on a tension roller at the same height inside the frame 1, and transmission is achieved by the rotation of the tension roller. Guide plates 3 are also disposed at both ends of the chain conveyor belt 2. The guide plates 3 are mounted on the support 4 of the frame 1 by support rods and the spacing between the two guide plates 3 is adjustable. A water receiving trough plate 5 is also fixed below the chain conveyor belt 2.

[0022] As described above, the support rod of the guide plate 3 passes through the support 4 and slides in a straight line. A fastening nut is provided on the support 4. The guide plate 3 can be fixed or slidably adjusted by the fastening nut pressing against the support rod or separating from the support rod.

[0023] During the cutting process, the tofu may slide on the conveyor due to resistance when the conveyor is transporting the carrier. To achieve effective transport of the carrier, an effective solution is provided here: protrusions are also provided on the chain plate of the chain conveyor belt 2, and the carrier 6 is placed on the chain conveyor belt 2 and locked between adjacent protrusions.

[0024] Please see the appendix Figure 4 In this embodiment, the top of the carrier 6 is provided with a receiving groove 601, and a handle 602 is provided at the top of the outer side of the carrier 6. The knife grooves are evenly spaced on the top of the carrier 6 and penetrate through the side wall of the carrier 6.

[0025] Please see the appendix Figure 5 In this embodiment, a strip-shaped hole is provided at the top of one end of the mounting frame 7. The length direction of the strip-shaped hole is perpendicular to the conveying direction of the conveying mechanism. A connecting rod passing through the strip-shaped hole is provided at the top of the first cutter 8. The first cutter 8 is movably connected to the mounting frame 7 by fasteners screwed onto the connecting rod. A limiting block that contacts the end of the mounting frame 7 is also provided at the top outer end of the first cutter 8. A cutting part is provided at the bottom of the first cutter 8. A rounded corner is provided on the end of the cutting part corresponding to the conveying direction of the conveying mechanism.

[0026] As described above, setting the shape and installation method of the first cutter can facilitate the adjustment of the spacing between adjacent first cutters so as to correspond with the blade groove of the carrier, thereby realizing continuous cutting of tofu.

[0027] Furthermore, the carriers are divided into different types, and the spacing between the blade grooves of the different types of carriers is different, so as to adapt to the cutting needs of tofu blocks of different sizes.

[0028] Please see the appendix Figure 6 and attached Figure 7In this embodiment, a linear telescopic device 9 is provided on the top of the other end of the mounting frame 7. The telescopic end of the linear telescopic device 9 is inserted into the mounting frame 7. A blade holder 12 is fixed on the telescopic end of the linear telescopic device 9.

A visual sensing device 13 is also provided at the bottom of the blade holder 12. The visual sensing device 13 is electrically connected to the linear telescopic device.

[0029] As described above, the visual sensing device is installed to facilitate the detection of whether a vehicle is passing below. When a vehicle passes, the visual sensing device receives a signal and transmits the signal to the external control system. The external control system controls the linear telescopic device (such as a cylinder, electric push rod, etc.) to extend and retract quickly. At the same time, it controls the linear telescopic device to extend and retract within a preset time to realize the cutting operation of tofu. When the vehicle has completely passed, the visual sensing device loses the signal, and the control system controls the linear telescopic device to be in the retracted state.
