Description

Technical Field

[0001] The present application relates to the field of dried tofu production equipment, and in particular to an automatic dried tofu cutting machine. Background Art

[0002] Dried tofu is one of the traditional soy products and a processed product of tofu. It is fresh, fragrant and refreshing, hard but tough, and can be stored for a long time without spoiling. Dried tofu contains a lot of protein, fat and carbohydrates, as well as calcium, iron and other minerals needed by the human body. After the dried tofu is made, it is usually a whole piece. In order to make it easier to eat, it needs to be cut into pieces.

[0003] For example, the dried tofu cutting device with patent number CN202010699406.9 has the following shortcomings in actual use:

[0004] The above-mentioned device can automatically rotate the dried tofu and automatically cut the dried tofu into pieces through the cooperation of the rotating component and the cutting component. However, the operator is required to load and unload and rotate the dried tofu during cutting, which cannot be used for continuous production and is not suitable for assembly line operation. Moreover, the rotation and loading and unloading of the dried tofu during cutting will reduce the cutting efficiency. Summary of the Invention

[0005] In order to improve the problem that dried tofu cannot be cut continuously and the cutting efficiency is low, the present application provides an automatic dried tofu cutting machine.

[0006] The present application provides an automatic cutting machine for dried tofu using the following technical solutions:

[0007] An automatic dried tofu cutting machine comprises a conveying structure and an outer shell fixed above a frame of the conveying structure with an openable and closable top cover, wherein a first cutting mechanism and a second cutting mechanism are arranged on the inner side of the outer shell;

[0008] The first cutting mechanism includes a first rotating shaft, both ends of which are rotatably connected to a first mounting base provided on the conveying structure frame, and a stepping motor is installed on the first mounting base to drive the first rotating shaft to rotate, and a plurality of circular cutting knives are fixed on the first rotating shaft at equal intervals;

[0009] The second cutting mechanism includes a second rotating shaft, both ends of which are rotatably connected to a second mounting seat arranged on the conveying structure frame, and the second mounting seat has the same structural size as the first mounting seat. A plurality of long cutting knives are fixedly provided around the surface of the second rotating shaft in equal parts, and a fixing ring is fixedly provided on the outer side of one end of the second rotating shaft, and the fixing ring is in close contact with the conveyor belt surface of the conveying structure.

[0010] By adopting the above technical solution, the conveying structure transports the dried tofu, the stepping motor drives the circular cutter to rotate, and the friction between the fixed ring and the conveying structure drives the long cutter to rotate. The circular cutter and the long cutter cut the dried tofu into pieces at perpendicular angles to each other during the transportation of the dried tofu. The dried tofu does not need to be rotated, and continuous assembly line operation can be carried out, which effectively improves the efficiency of cutting the dried tofu.

[0011] Preferably, the first mounting seat includes two vertical channel steels fixed on the frame of the conveying structure, a horizontal plate is fixed at the upper ends of the two vertical channel steels, a mounting plate is set between the two channel steels for lifting and sliding, the stepper motor is fixed on the mounting plate at the corresponding position, the end of the first rotating shaft is rotatably connected to the mounting plate, a threaded rod is fixed at the upper end of the mounting plate, a circular hole is opened on the horizontal plate, the threaded rod is movably inserted into the circular hole, and two nuts are threadedly connected to the threaded rod and are respectively clamped on both sides of the horizontal plate.

[0012] By adopting the above technical solution, the operator can adjust the two nuts to achieve the lifting and lowering of the mounting plate, which is convenient for debugging the positions of the circular cutter and the long cutter, and is more convenient for maintenance of the equipment during long-term use.

[0013] Preferably, a brush is provided on one side of the first rotating shaft and is distributed parallel to the first rotating shaft. The brush comprises a metal base and bristles, and the bristles are in contact with the blade of the circular cutter.

[0014] By adopting the above technical solution, the bristles can scrape off the dried tofu scraps attached to the circular cutter, thereby improving the cleanliness of the circular cutter.

[0015] Preferably, the brush also includes semi-cylindrical handles fixed on both ends of the metal base, and support plates are fixed on both sides of the frame of the conveying structure. Vertical grooves and semi-circular grooves connected to each other are opened on the support plates, and the semi-cylindrical handles are movably clamped in the semi-circular grooves at corresponding positions.

[0016] By adopting the above technical solution, the operator can rotate the two semi-cylindrical handles to remove the middle semi-circular groove and vertical groove of the semi-cylindrical wrench upwards, and then remove the bristles. Similarly, the bristles can also be installed, making cleaning the equipment more convenient.

[0017] Preferably, angle steel for receiving scraps is fixed to the side of the metal base.

[0018] By adopting the above technical solution, when the bristles are removed, when the semi-cylindrical handle is rotated, the debris on the bristles will fall to the inside of the angle steel, making cleaning more convenient.

[0019] Preferably, a flexible pressure strip is fixed on the side of the long cutting knife for pressing the dried tofu during cutting.

[0020] By adopting the above technical solution, the flexible layering strips can press the dried tofu tightly, preventing the dried tofu blocks from being pulled by the cutter when cutting the dried tofu, and can ensure that the incision is more neat, which helps to improve product quality.

[0021] Preferably, the outer surface of the conveyor belt of the transmission structure is provided with a plurality of grid-shaped grooves, and the cutting paths of the long cutter and the circular cutter are aligned with the grid-shaped grooves.

[0022] By adopting the above technical solution, the blades of the long cutter and the circular cutter can cut into the grid-shaped grooves, ensuring that the dried tofu is cut more thoroughly and preventing the dried tofu blocks from sticking to each other.

[0023] Preferably, a connecting plate is fixed to the outer side of the second rotating shaft, and a plurality of first connecting holes are opened on the connecting plate. A connecting ring is fixed to the inner side of the fixing ring, and a plurality of second connecting holes are opened on the connecting ring. The connecting plate and the connecting ring are fixedly connected by bolts arranged in the first connecting holes and the second connecting holes.

[0024] By adopting the above technical solution, the long cutter is prone to offset from the grid-shaped groove after long-term use. At this time, the second shaft can be freely rotated by removing the bolt, and the bolt can be re-fastened after adjusting the position of the long cutter.

[0025] Preferably, an anti-slip rubber ring is fixedly provided on the outer side of the fixing ring, and the anti-slip rubber ring is in close contact with the conveyor belt of the conveying structure.

[0026] By adopting the above technical solution, the anti-slip rubber ring can prevent slipping between the conveyor belt and the fixed ring of the transmission structure, ensure the continuous rotation of the second rotating shaft, and improve the cutting effect.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The dried tofu is cut into pieces using a circular cutter and a long cutter with mutually perpendicular cutting directions. The dried tofu can be cut into pieces without adjusting the direction of the tofu. In addition, the conveying structure continues to run during the cutting process. The stepper motor drives the first rotating shaft and the circular cutter to rotate. The friction between the fixed ring and the conveyor belt drives the second rotating shaft and the long cutter to rotate, which can realize continuous flow operation.

[0029] 2. The friction between the fixed ring and the conveyor belt drives the long cutter to rotate synchronously with the conveyor belt. When the dried tofu passes by, the long cutter can maintain the same moving speed as the dried tofu when cutting into the dried tofu, preventing the long cutter from rotating too fast or too slow to cause damage to the dried tofu blocks, thereby improving the product quality of the dried tofu blocks.

[0043] The following is combined with Figure 1-6 This application is described in further detail.

[0044] The embodiment of the present application discloses an automatic cutting machine for dried tofu.

[0045] Example 1

[0046] Reference Figure 1 、 2, a dried tofu automatic cutting machine, comprising a conveying structure 1 and an outer shell body 2 with an openable and closable top cover fixedly mounted above the frame of the conveying structure 1, a first cutting mechanism 3 and a second cutting mechanism 4 are arranged on the inner side of the outer shell body 2, the conveying structure 1 is an existing technology and can adopt an existing structure, because it is not the main technology, it will not be described in detail, the first cutting mechanism 3 comprises a first rotating shaft 31, and a plurality of equally spaced circular cutters 32 are fixed on the first rotating shaft 31, for cutting the dried tofu into strips, the second cutting mechanism 4 comprises a second rotating shaft 41, and a plurality of long cutters 42 are fixedly mounted around the surface of the second rotating shaft 41 in equal parts, and a flexible pressure strip 44 for pressing the dried tofu is fixed at the side end of the long cutter 42, in addition, a plurality of grid-like grooves 8 are arranged on the outer surface of the conveyor belt of the conveying structure 1, and the cutting paths of the long cutters 42 and the circular cutters 32 are aligned with the grid-like grooves 8.

[0047] Through the above-mentioned arrangement, the conveying structure 1 drives the dried tofu to be transported. When passing under the first cutting mechanism 3 and the second cutting mechanism 4, the circular cutter 32 rotates to cut the dried tofu into strips, and then the long cutter 42 cuts the dried tofu strips into blocks. Moreover, during cutting, the flexible layer 44 can press the dried tofu tightly to improve the cutting effect, and the grid-shaped groove 8 can ensure that the blades of the long cutter 42 and the circular cutter 32 can completely penetrate the dried tofu, cutting the dried tofu more thoroughly and preventing the dried tofu blocks from sticking together. The dried tofu can be cut into blocks after passing under the outer shell 2, which is convenient for assembly line operation.

[0048] Reference Figure 3 The two ends of the first rotating shaft 31 and the second rotating shaft 41 are connected to the frame of the conveying structure 1 through the first mounting seat and 5 and the second mounting seat 6 respectively, ensuring that the first rotating shaft 31 and the second rotating shaft 41 can achieve the rotation effect, and the first mounting seat 5 and the second mounting seat 6 have the same structure and size. The first mounting seat 5 includes two vertical channel steels 51 fixed to the frame of the conveying structure 1, and a horizontal plate 52 is fixed to the upper end of the two vertical channel steels 51. A mounting plate 53 is set between the two vertical channel steels 51 for lifting and sliding. The end of the first rotating shaft 31 is rotatably connected to the mounting plate 53, and a threaded rod 54 is fixed to the upper end of the mounting plate 53. A round hole is opened on the horizontal plate 52, and the threaded rod 54 is movably inserted into the round hole. Two nuts 55 are threaded on the threaded rod 54, and the two nuts 55 are respectively clamped on both sides of the horizontal plate 52.

[0049] Through the above arrangement, the operator can adjust the height of the threaded rod 54 through the two nuts 55, and then adjust the height of the mounting plate 53, so as to adjust the height of the circular cutter 32 and the long cutter 42. When assembling the equipment, it is convenient for the assemblers to debug the height of the cutters, and when replacing cutters of different sizes, the height of the cutters can be adjusted in time, which is further convenient for use.

[0050] Reference Figure 3 、 6A stepper motor 33 is fixed on one of the mounting plates 53 of the first mounting seat 5, and the output shaft of the stepper motor 33 is connected to one end of the first rotating shaft 31 through a coupling, and the stepper motor 33 provides rotational power to the first rotating shaft 31 and the circular cut 32. A fixing ring 43 is provided on the outside of one end of the second rotating shaft 41, and a connecting plate 45 is fixed on the outside of the second rotating shaft 41, and a plurality of first connecting holes 46 are provided on the connecting plate 45. A connecting ring 47 is fixed on the inner side of the fixing ring 43, and a plurality of second connecting holes 48 are provided on the connecting ring 47. The connecting plate 45 and the connecting ring 47 are fixedly connected by bolts provided in the first connecting holes 46 and the second connecting holes 48, and an anti-slip rubber ring 49 is fixed on the outside of the fixing ring 43, and the anti-slip rubber ring 49 is in close contact with the conveyor belt.

[0051] Through the above-mentioned arrangement, the power of the first rotating shaft 31 is provided by the stepping motor 33, which drives the circular cutter 32 to cut the dried tofu. The power of the second rotating shaft 41 is provided by the friction between the anti-slip rubber ring 49 and the conveyor belt. The friction drives the fixed ring 43 to rotate, and then drives the second rotating shaft 41 to rotate. When the dried tofu is transported on the conveyor belt, the long cutter 42 can maintain the same moving speed as the dried tofu when cutting into the dried tofu, preventing the long cutter 42 from rotating too fast or too slow to cause damage to the dried tofu block, thereby improving the product quality of the dried tofu block. In addition, during long-term use, the long cutter 42 is prone to offset from the grid-shaped groove 8. At this time, the friction between the anti-slip rubber ring 49 and the conveyor belt can be released by removing the bolts. The second rotating shaft 41 is rotated, the position of the long cutter 42 is adjusted, and then the bolts can be re-fastened.

[0052] Reference Figure 3 、 4 A brush 7 is provided on one side of the first rotating shaft 31 and is distributed parallel to the first rotating shaft 31. The brush 7 includes a metal base 72 and bristles 71. The bristles 71 are in contact with the blade of the circular cutter 32, and the side of the metal base 72 is fixed with an angle steel 77 for receiving the scraps. Semi-cylindrical handles 73 are fixed at both ends of the metal base 72. Support plates 74 are fixed on both sides of the frame of the conveying structure 1. Vertical grooves 75 and semi-circular grooves 76 that are connected to each other are opened on the support plates 74. The semi-cylindrical handles 73 are movably engaged in the semi-circular grooves 76 at the corresponding positions.

[0053] Through the above-mentioned setting, the bristles 71 can scrape off the dried tofu debris attached to the circular cutter 32, thereby improving the cleanliness of the circular cutter. If a large amount of debris accumulates on the bristles 71, the operator can rotate the semi-cylindrical handle 73, and the debris accumulated on the bristles 71 will fall to the inside of the angle steel 77. At this time, the semi-cylindrical handle 73 is rotated to the bottom of the vertical groove 75, and the semi-cylindrical handle 73 can be taken out upwards to clean the bristles 71.

[0054] It should be noted that the transmission structure 1 is composed of a conveyor belt and a servo motor, and the device is also provided with switches, wires, controllers and other devices, which are not the main technologies and will not be described in detail.

[0055] The implementation principle of the automatic cutting machine for dried tofu in the embodiment of the present application is as follows: the conveying structure 1 drives the dried tofu to be transported, and when passing under the first rotating shaft 31, the first rotating shaft 31 driven by the stepping motor 33 drives the circular cutter 32 to cut the dried tofu into strips, and the debris attached to the circular cutter 32 will be scraped off by the bristles 71. When a large amount of debris is accumulated, the operator can rotate the semi-cylindrical handle 73 to remove the bristles 71 and clean it. As the conveying structure 1 continues to transport, the friction between the non-slip rubber ring 49 and the conveyor belt drives the second rotating shaft 41 to rotate, and then drives the long cutter 42 to rotate. The long cutter 42 can further cut the dried tofu strips into dried tofu blocks, and when the long cutter 42 cuts, the flexible layer 44 will press the dried tofu tightly to improve the cutting effect. Finally, the dried tofu blocks continue to be transported along with the conveying structure 1 and are collected by the prepared collection box;

[0056] The blades of the long cutter 42 and the circular cutter 32 can cut into the grid-shaped groove 8, ensuring that the dried tofu is cut more thoroughly and preventing the dried tofu pieces from sticking to each other. In addition, the long cutter 42 is prone to offset from the grid-shaped groove 8 during long-term use. At this time, the bolt can be removed to freely rotate the second rotating shaft 41, and the bolt can be re-fastened after adjusting the position of the long cutter 42.

[0057] In summary, the device can cut the dried tofu in transit into pieces without rotating the dried tofu, which is convenient for streamlined operation, and can perform continuous cutting, effectively improving the cutting efficiency of the dried tofu.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
