Description

Technical Field

[0001] The invention relates to automatic fruit peel cutting, in particular to an automatic soft fruit peel cutting device. Background Art

[0002] Orange peel tastes sweet and bitter, but has the fragrance of orange. It is the dry peel made from the peel of citrus fruit after being dried. This kind of peel can be stored for a long time if kept in dry conditions, so it is called dried tangerine peel.

[0003] Orange peel has medicinal value, specifically it has the following medicinal effects: preventing motion sickness, treating frostbite, treating chronic bronchitis, treating cough, treating mastitis, treating stomach cold and vomiting, treating colds, and soaking in water to reduce internal heat, etc.

[0004] Therefore, orange peels are mostly dried and then stored. However, the peeled orange peels are of different sizes, which is extremely inconvenient to use. If they are directly cut into pieces, the orange peels are easily cut into block materials with extremely large width deviations, which is still not very convenient to use. In addition, during the cutting process, the inventors also found that the cutting efficiency is low when the orange peels are cut into block materials. The inventors studied the cutting process and found that the orange peels are soft, and there is no mechanism to fix the orange peels during the cutting process. With the existing cutting mechanism, the orange peels are easily bounced off by the cutter, so it is difficult for the orange peels to be automatically fed into the cutting area, which leads to low cutting efficiency.

[0005] After long-term research, the inventor cut the orange peel into blocks of similar size for easy use. However, when cutting the orange peel into blocks, the orange peel needs to be cut into strips first, and then the strips of orange peel need to be cut into blocks.

[0006] However, the existing strip cutting machines mostly use two circular cutting rollers for cutting, such as the Chinese patent: a strip cutting machine with adjustable blades (Announcement No.: CN221583843U). Although it can cut orange peels into strips, its cutting efficiency is low. The main reason is that orange peels are light. When cutting, some orange peels will bounce off after encountering the blades. In addition, the orange peels are mainly fed by their gravity and the drive of the circular rollers, which leads to low efficiency in cutting orange peels. Existing cutting machines all require a feeding mechanism to clamp the material and then stably feed the material into the cutting area. For example, a Chinese patent: an ultra-precision thermoplastic composite material pelletizer (publication number: CN113524493A) discloses that the material is cut into particles by rotating a rotary knife roller and a fixed knife, but the pelletizer still requires an upper pressure roller and a lower pressure roller to feed the material strips, and the structure of the material strips is not high-quality software. Without the premise of stably feeding the strip-shaped orange peel, the cutting mechanism composed of the knife roller and the fixed knife cannot complete the cutting of the orange peel.

[0026] like Figure 1 and Figure 2 As shown, an automatic dicing device for soft fruit peels comprises a frame 50, on which a conveying mechanism 30 and a cutting mechanism 40 are installed. The cutting mechanism 40 comprises a chassis 1 with a feeding port, in which a strip cutting mechanism 10 for cutting materials into strips and a cutting mechanism 20 for cutting strip materials into blocks are installed. The discharge port of the conveying mechanism 30 is located above the feeding port. The conveying mechanism 30 is a prior art, and a plate conveyor or a belt conveyor can be used. The conveying mechanism 30 conveys the soft fruit peels into the cutting mechanism 40, and the soft fruit peels are first cut into strips by the strip cutting mechanism, and the strip soft fruit peels are then cut into blocks by the cutting mechanism 20.

[0027] In this embodiment, if Figure 2As shown, the cutting mechanism 40 includes a chassis 1 with a feeding port, and the feeding port is set on the top of the chassis 1, and the material enters the chassis 1 from the feeding port, and a strip cutting mechanism 10 for cutting the material into strips and a block cutting mechanism 20 for cutting the strip material into blocks are installed in the chassis 1, and the discharge port of the strip cutting mechanism 10 is located above the feed port of the block cutting mechanism 20. After the material enters the chassis 1 from the feeding port, the material is cut into strips by the strip cutting mechanism 10, and then the strip material falls from the discharge port of the strip cutting mechanism 10 onto the block cutting mechanism 20, and the strip material is cut into blocks by the block cutting mechanism 20. By first cutting the material into strips, the width of the material meets the requirements, and then the strip material is cut into blocks, so that the length of the material also meets the requirements, and then the cut material meets the size requirements, and there will be no block material exceeding the size requirements.

[0028] In this embodiment, the material to be cut is mainly soft peels, such as tangerine peels. When the soft peels are cut into strips, due to the irregular shape of the peels and the softness of the peels, if the peels fall into the cutting area entirely by their own weight, the efficiency of cutting the peels will be low. In this embodiment, if Figure 3 and Figure 4 As shown, the slitting mechanism 10 includes a rotatable cutting roller 2 and a rotatable feeding roller 3. The cutting roller 2 and the feeding roller 3 are driven by a driving device, and the driving device is installed on a frame 50. Figure 5 and Figure 6 As shown, a plurality of cutting blades 21 are axially spaced apart on the cutting roller 2, a cutting groove 32 corresponding to the cutting blade 21 is provided on the feeding roller 3, and the outer circle of the cutting blade 21 is located in the cutting groove 32, so that the cutting blade 21 can cut the material during the circumferential rotation, and a feeding notch 31 extending along the axial direction is provided on the outer circumference of the roller body 34 of the feeding roller 3, and the feeding roller 3 can continuously feed the material to the cutting blade 21 through the feeding notch 31 during the rotation process, thereby improving the cutting efficiency and cutting rate of the material, and there is a blanking gap between the roller body 34 and the cutting roller 2, as shown in FIG. Figure 7 As shown in C, after the material is cut into strips, the strip material falls from the blanking gap, and when the feeding notch 31 rotates from the cutting area to the bottom of the feeding roller 3, it can also play a certain role in carrying the strip material, thereby facilitating the falling of the material. The blanking gap is located above the feed port of the cutting mechanism 20, and the cut strip material falls from the blanking gap onto the cutting mechanism 20.

[0029] In this embodiment, if Figure 5 and Figure 6As shown, the cutting roller 2 includes a cutting shaft 24, on which a plurality of pads 22 are installed, and a cutting blade 21 is arranged between two adjacent pads 22. The cutting blade 21, the pad and the cutting shaft 24 are all installed by flat keys, thereby ensuring the synchronous rotation of the cutting blade 21, the pad 22 and the cutting shaft 24. The pad 22 and the cutting blade 21 are locked by first locking nuts 23 arranged at both axial ends of the cutting shaft 24. The first nut is locked to ensure the axial position of the pad 22 and the cutting blade 21, which is convenient for the reliable operation of the cutting blade 21. The pad 22 determines the distance between the two cutting blades 21, and thus determines the cutting width of the material. The gap between the outer circle of the roller body 34 and the outer circle of the pad 22 forms a blanking gap. Through the blanking gap, not only the blanking efficiency of the material is improved, space is provided for the falling of the material, but also interference between the feeding roller 3 and the pad 22 is avoided.

[0030] In this embodiment, if Figure 8 As shown, the circular track formed by the rotation of the cutting blade 21 and the circular track formed by the bottom of the cutting groove 32 are mutually circumscribed circles, so that during the cutting process, the cutting blade 21 can completely cut the material, thereby improving the cutting quality of the material.

[0031] In this embodiment, if Figure 7 As shown, the feeding notch 31 has a pressure surface 311 and a feeding surface 312 which are at an angle to each other. With the rotation direction of the feeding roller 3 as the front, the pressure surface 311 is located behind the feeding surface 312. During the rotation of the feeding roller 3, the feeding surface 312 approaches the cutting blade 21, and the material in the feeding notch 31 slides into the cutting area along the feeding surface 312. When the material contacts the cutting blade 21, part of the material will be bounced away by the cutting blade 21. However, as the pressure surface 311 approaches the cutting blade 21 again, the pressure surface 311 restricts the material, and the pressure surface 311 applies pressure to the material, forcing the material to contact the cutting blade 21, thereby realizing the cutting of the material. After the cutting, as the feeding surface 312 rotates to the blanking area, the feeding surface 312 tilts downward, thereby facilitating the strip material on the feeding surface 312 to fall into the blanking area.

[0032] In this embodiment, if Figure 7 and Figure 8 As shown, the bottom of the feeding notch 31 is located on the circular track formed by the bottom of the cutting notch 32, so that the feeding notch 31 can ensure that the cutting blade 21 completely cuts the material in the feeding notch 31 while feeding the material.

[0033] In this embodiment, if Figure 5 and Figure 6As shown, the feeding roller 3 also includes a feeding shaft 33, a roller body 34 is installed on the feeding shaft 33, and the roller body 34 is locked by second locking nuts 35 installed at both axial ends of the feeding shaft 33, and a flat key is provided between the roller body 34 and the feeding shaft 33 to ensure the synchronous rotation of the roller body 34 and the feeding shaft 33, and the circumferential position of the roller body 34 is ensured by locking with the second locking nut 35, thereby avoiding the knife hitting phenomenon and ensuring the reliable cutting of the cutting blade 21.

[0034] In this embodiment, if Figure 3 and Figure 4 As shown, the cutting roller 2 and the feeding roller 3 are both rotatably installed in the chassis 1. A comb plate 4 is also installed in the chassis 1. The comb plate 4 is located on the outside of the blanking gap, and the comb teeth of the comb plate 4 are located between two adjacent cutting blades 21. The comb plate 4 resists the strip material, thereby ensuring that all the strip materials fall into the blanking area below the blanking gap.

[0035] In this embodiment, an axially extending mounting seat 5 is installed in the chassis 1. Fig. 9 and Fig.10 As shown, the mounting seat 5 is located below the cutting roller 2, and the mounting seat 5 is a rectangular column. Screw holes are provided on the axial end faces of the mounting seat 5, and the mounting seat 5 and the side wall of the chassis 1 are locked by locking screws. As shown in the figure, the comb plate 4 is installed on the mounting seat 5, and the comb plate 4 and the mounting seat 5 are installed with locking screws. Preferably, a countersunk screw hole is provided on the mounting seat 5, and then the comb plate 4 is installed on the mounting seat 5 by countersunk screws. Since the cutting area of ​​the strip cutting mechanism 10 is long, the comb plate 4 is also long, which increases the difficulty of processing the comb plate 4. Therefore, in this embodiment, the comb plate 4 has a multi-section structure. During processing, it is processed in sections and then installed on the mounting seat 5, and then spliced ​​into a comb plate 4 that meets the use requirements.

[0036] In this embodiment, if Fig.10 and Fig.11 As shown, an avoidance slope 41 is provided on the outer surface of the top of the comb plate 4, and the avoidance slope 41 gradually moves away from the cutting roller 2 from top to bottom, thereby avoiding the contact between the pad 22 and the comb plate 4. At the same time, by setting the avoidance slope 41, the top of the comb plate 4 forms a pointed part, so that the top of the comb plate 4 can be as close to the outer circumference of the pad 22 as possible, thereby ensuring that the comb plate 4 can completely block the strip materials into the falling area.

[0037] In this embodiment, if Figure 8As shown, on the axial projection plane, the feeding notch 31 is a right-angled groove, so that the feeding notch 31 is easy to process. The vertical foot of the feeding notch 31 is located on the circumference where the cutting groove 32 is located. There are several feeding notches 31, and several feeding notches 31 are evenly distributed on the same circumference, thereby improving the feeding efficiency of the material, thereby improving the cutting efficiency of the material.

[0038] In this embodiment, the power output end of the cutting shaft 24 of the cutting roller 2 is connected to a driving device, preferably, the driving device includes a driving motor, and the driving motor and the cutting shaft 24 are connected through a chain or belt transmission, such as Figure 4 As shown, a driving gear is provided at the other end of the cutting shaft 24, and a driven gear meshing with the driving gear is provided on the feeding shaft 33 of the feeding roller 3, and the transmission ratio of the driving gear to the driven gear is greater than, therefore, the rotation speed of the feeding roller 3 is greater than the rotation speed of the cutting roller 2, further improving the feeding efficiency of the material, thereby improving the cutting efficiency of the material.

[0039] In this embodiment, the soft peel cut into strips is relatively soft, and the peel needs to be cut into blocks. During the high-speed rotation of the moving knife, the peel is easily bounced off, so that the peel has no support point, and after the peel is cut off, there is no pulling force to pull the subsequent peel, making the peel feeding extremely difficult, resulting in low cutting efficiency. In this embodiment, if Fig.12 As shown, the slicing mechanism 20 includes a fixed knife 200 fixedly installed in the chassis 1, a knife roller 100 that performs a rotating motion, and a feeding member 300 that feeds materials to the feeding area of ​​the knife roller 100. The knife roller 100 is driven by a driving mechanism, and the driving mechanism includes a driving motor. The power output end of the driving motor is connected to the power output end of the knife roller. In this embodiment, a chain drive or a belt drive can be used between the driving motor and the knife roller, such as Fig.15 As shown, the material receiving box 400 has an open slot, and the knife roller 100 of the dicing mechanism 20 is located in the material receiving box 400. The knife roller 100 can be put into the material receiving box 400 through the open slot, and the two ends of the shaft of the knife roller 100 pass through the material receiving box 400. The dicing area of ​​the knife roller 100 and the fixed knife 200 is located at the open slot. In this embodiment, Fig.13 As shown, the cutting area of ​​the knife roller 100 and the fixed knife 200 is in the vicinity of the area where the fixed knife blade 201 and the movable knife blade 101 are at the minimum distance D, the material receiving box 400 and the cutting mechanism 20 are both located in the chassis 1, and both ends of the knife roller 100 are rotatably mounted on the chassis 1, and the fixed knife 200 is fixedly mounted in the chassis 1. In this embodiment, Fig.12As shown, the cutting mechanism 20 includes a fixed fixed knife 200 and a knife roller 100 that performs a rotating motion. The fixed knife 200 is installed in the chassis 1, and the position of the fixed knife 200 relative to the chassis 1 is fixed. Furthermore, a mounting seat 5 is installed in the chassis 1, and the fixed knife 200 is detachably mounted on the mounting seat 5. Screw holes are provided at both axial ends of the mounting seat 5. The mounting seat 5 and the side wall of the chassis 1 are locked by locking screws, and the fixed knife 200 and the mounting seat 5 are also detachably mounted by locking screws. In this embodiment, the comb plate 4 and the fixed knife 200 are both installed on the rear side wall of the mounting seat 5, and the bottom of the comb plate 4 abuts against the top of the fixed knife 200. Preferably, the thickness of the comb plate 4 is greater than or equal to the thickness of the fixed knife 200. Preferably, the thickness of the comb plate 4 is the same as the thickness of the fixed knife 200, so that no step is formed between the comb plate 4 and the fixed knife 200, thereby ensuring that the material can fall smoothly.

[0040] In this embodiment, during the rotation of the knife roller 100, the knife roller 100 and the fixed knife 200 cooperate to cut the material. Fig.14 As shown, the knife roller 100 is provided with a movable knife blade 101 extending in the axial direction, and the knife roller 100 is also provided with a discharge groove 102 corresponding to the movable knife blade 101. During processing, the discharge groove 102 is opened on the knife roller 100, and the movable knife blade 101 is formed between the two discharge grooves 102. The rear end notch of the discharge groove 102 and the outer circumference of the knife roller 100 form the movable knife edge, and the part between the two adjacent discharge grooves 102 forms the movable knife back. The thickness of the knife back gradually thickens from the outside to the inside in the radial direction, thereby ensuring the service life of the movable knife. As shown in the figure, the cutting mechanism 20 also includes a knife roller. The feeding piece 300 that feeds the feeding area 100 has the rotation direction of the knife roller 100 as the front, and the feeding piece 300 is located above the knife roller 100, and the area where the knife roller 100 is located below the feeding piece 300 is the feeding area, the fixed knife 200 is located in the front side of the outlet of the feeding piece 300, the moving knife blade 101 of the moving knife faces the fixed knife 200, and the shortest distance between the fixed knife blade 201 of the fixed knife 200 and the moving knife blade 101 of the moving knife is less than the thickness of the material. Therefore, when the moving knife blade 101 is at the shortest distance from the fixed knife blade 201, the material is cut, and then the material becomes block-shaped.

[0041] In this embodiment, if Fig.16As shown, the feeding member 300 has a U-shaped plate 301, which is installed on the fixed knife 200, and a feeding trough 304 is formed between the U-shaped plate 301 and the fixed knife 200. The material is accumulated in the feeding trough 304, and the material falls into the feeding area of ​​the knife roller 100 under the action of gravity. During the rotation of the knife roller 100, a thrust can be applied to the material to move the material toward the fixed knife 200. During the falling process, most of the material directly falls into the discharge trough 102, and the knife roller 100 can easily The material is transported between the moving blade 101 and the fixed blade 201, thereby realizing the cutting of the material, and the end of a small part of the material cannot fall into the discharge chute 102. As the knife roller 100 rotates, the end of the material contacts the rear side wall of the fixed knife 200. At this time, the rear side wall of the fixed knife 200 acts as a blocking surface 203 to block the material. As the knife roller 100 continuously applies thrust to the material, the material will be arched due to its softness. The arched material has a certain elastic restoring force, and the front end of the material is Under the action of the elastic restoring force, the material has a tendency to be inserted into the knife roller 100. Therefore, when the front end of the material is just aligned with the discharge groove 102, the front end of the material will be inserted into the discharge groove 102, thereby completing the cutting of the material. The cut material is located in the discharge groove 102, and as the knife roller 100 rotates, it falls out of the discharge groove 102, thereby preventing the block material from accumulating in the discharge groove 102 and affecting the cutting of the material. Therefore, the material in the feeding piece 300 contacts the knife roller 100 under the action of gravity, and then passes through the knife roller 100. The rotation applies thrust to the material, thereby causing the material to move toward the fixed knife 200. During the movement, the front end of part of the material enters the discharge chute 102, and then the fixed knife 200 and the knife roller 100 cooperate to cut the material into blocks. The remaining material can be blocked by the abutment surface 203 of the fixed knife 200, and the remaining material can enter the subsequent discharge chute 102, thereby cutting the material into several blocks. Therefore, there is no need to use a feeding mechanism to clamp the material, making the structure of the entire cutting device simpler.

[0042] In this embodiment, if Fig.13 As shown, there is a gap between the bottom of the feeding trough 304 and the circumference where the fixed knife blade 201 is located. Furthermore, the height of the gap is greater than the thickness of the material. Preferably, the height of the gap is 1.5-2.5 times greater than the thickness of the material, thereby avoiding interference between the fixed knife blade 201 and the feeding trough 304. At the same time, by adjusting the gap, it can also ensure that the bottom layer of material is separated from the feeding trough 304 and can contact the knife roller 100, thereby ensuring the reliability of material cutting. Of course, in this embodiment, both axial ends of the movable knife blade 101 pass through the knife roller 100, thereby ensuring that the material in the feeding trough 304 can be cut by the knife roller 100.

[0043] In this embodiment, if Fig.13 As shown, the bottom of the two side walls of the feeding trough 304 is an arc surface 305, and the distance between the arc surface 305 and the moving knife blade 101 increases from front to back. That is to say, when the material is between the feeding trough 304 and the knife roller 100, the thickness of the material at the rear side is greater than the thickness of the material at the front side, which makes it easier to push the material forward.

[0044] In this embodiment, if Fig.16 As shown, a material baffle plate 302 extending axially is also provided at the rear bottom of the U-shaped plate 301. When the movable knife contacts the material, the material baffle plate 302 can block the material to prevent the material from popping out from the rear side of the feeding trough 304, so that the material can only move toward the direction of the fixed knife 200, thereby ensuring the cutting rate of the material.

[0045] In this embodiment, if Fig.16 As shown, the front end surfaces of the two side walls of the U-shaped plate 301 are provided with outwardly folded wing plates 303, and the wing plates 303 are detachably connected to the fixed knife 200, thereby facilitating the disassembly of the feeding piece 300.

[0046] In this embodiment, on the horizontal projection plane, the comb plate 4 and the feeding piece 300 form an annular cavity. Preferably, the annular cavity is a rectangular cavity. The comb plate 4 ensures that all the strip materials fall into the rectangular cavity, and the strip materials pass through the rectangular cavity frame column. Even if the strip materials are bounced off by the high-speed rotating moving knife, it can be ensured that the strip materials will not be ejected from the rectangular cavity, thereby allowing the strip materials to be cut in an orderly manner by the passive knife and the fixed knife 200.

[0047] In this embodiment, if Fig.13 and Fig.15 As shown, a retreat slope 202 is provided at the bottom of the fixed knife 200. From back to front, the shortest distance between the retreat slope 202 and the circumference of the fixed knife blade 201 gradually increases, thereby ensuring that the movable knife blade 101 does not contact the fixed knife 200, thereby ensuring the reliability of the use of the knife roller 100.

[0048] In this embodiment, if Fig.17As shown, in order to fine-tune the position of the feeding roller 3 so as to facilitate the alignment of the cutting blade 21 and the cutting groove 32, screw adjustment devices are provided at both ends of the feeding roller 3. At the same time, in order to ensure the gap between the moving knife and the fixed knife 200, it is also necessary to fine-tune the position of the moving knife. Therefore, screw adjustment devices are also provided at both ends of the fixed knife 200. In this embodiment, the screw adjustment device includes a fixed plate 51, a top pressure screw 53, a tensioning screw 54 and a fastening nut 52. For the feeding roller 3, both ends of the feeding shaft 33 are rotatably mounted on the chassis 1 through a bearing seat. A sliding groove is provided on the chassis 1, and the bearing seat is slidably mounted in the sliding groove. The fixed plate 51 is fixedly mounted in the sliding groove. Optionally, the fixed plate 51 and the sliding groove can Welding or clamping can be used. When clamping, clamping grooves can be opened on the upper and lower side walls of the sliding groove, and the upper and lower ends of the fixing plate 51 can be clamped in the corresponding clamping grooves. Of course, in the actual process, if a sliding groove is opened on the chassis 1, a thin block is formed on the chassis 1, and the thin block can also be used as the fixing plate 51. A threaded through hole that is threadedly matched with the pressing screw 53 is opened on the fixing plate 51, and a contact blind hole corresponding to the pressing screw 53 is opened on the outer side wall of the bearing seat. One end of the pressing screw 53 passes through the threaded through hole and abuts against the contact blind hole. A fastening nut 52 is also installed on the pressing screw 53 between the head of the pressing screw 53 and the fixing plate 51. A through hole is also opened on the fixing plate 51 for the tensioning screw 54 to pass through. The screw hole corresponding to the tensioning screw 54, one end of the tensioning screw 54 passes through the through hole and is locked with the screw hole, and a fastening nut 52 is also installed on the tensioning screw 54 between the head of the tensioning screw 54 and the fixing plate 51. When in use, the top pressure screw 53 is installed first, and the feeding roller 3 is moved toward the cutting roller 2 by rotating the top pressure screw 53. When the cutting blade 21 contacts the cutting groove 32, it indicates that the feeding roller 3 has moved into place. At this time, the cutting blade 21 has also completed the knife alignment, and then the corresponding fastening nut 52 is locked to ensure the stability of the position of the top pressure screw 53, and then the tensioning screw 54 is locked with the screw hole, and the corresponding fastening nut 52 is locked, so that the bearing seat is pulled by the tensioning screw 54, so that the tensioning screw The dual functions of 54 and the top pressure screw 53 realize the installation of the feeding roller 3, and at the same time ensure the stability of the relative position of the feeding roller 3, thereby improving the reliability of material cutting. Preferably, there are two tensioning screws 54, which are respectively located on the upper and lower sides of the top pressure screw 53. Similarly, bearing seats are provided at both ends of the knife roller 100, and sliding grooves are also provided on the axial side walls of the chassis 1. The sliding grooves extend along the front and rear directions, and the bearing seats are slidably installed in the sliding grooves. The connection relationship between the bearing seats and the screw adjustment device is the same as the connection method between the bearing seats at both ends of the feeding shaft 33 and the screw adjustment devices. Therefore, the horizontal position of the moving knife can be adjusted through the screw adjustment device, and then the minimum distance between the fixed knife blade 201 and the moving knife blade 101 can be adjusted.When the movable knife is worn out after long-term use, it needs to be polished to ensure the sharpness of the movable knife blade 101. Of course, after the fixed knife blade 201 is worn, it is also necessary to polish the fixed knife blade 201. After the fixed knife blade 201 and the movable knife blade 101 are polished, the distance between the fixed knife blade 201 and the movable knife blade 101 will change, thereby affecting the cutting of the material. At this time, the screw adjustment device is required to adjust the position of the knife roller 100, so that the minimum distance between the fixed knife blade 201 and the movable knife blade 101 meets the requirements, ensuring the reliability of material cutting.

[0049] The working process of the present invention is as follows: orange peels are placed on the conveying mechanism 30, and the conveying mechanism 30 puts the orange peels from the feeding port of the chassis 1 between the cutting roller 2 and the feeding roller 3, and most of the orange peels enter the feeding gap 31. As the feeding roller 3 rotates, the orange peels in the feeding gap 31 gradually approach the cutting blade 21 and are finally cut by the cutting blade 21. In addition, the feeding gap 31 also has a pressing effect during the rotation process, that is, the orange peels are pressed, thereby ensuring the cutting efficiency of the orange peels. The cut orange peels are in strips, and the maximum width does not exceed the width between two adjacent cutting blades 21. The strips of orange peels fall into the feeding member 300 from the gap between the falling materials, and the strips of orange peels fall into the feeding member 300 in the falling material gap. During the feeding process, the resistance of the comb plate 4 can ensure that the orange peels fall completely into the feeding piece 300. The orange peels in the feeding piece 300 contact the knife roller 100 under the action of gravity. As the knife roller 100 rotates, the front end of most of the orange peels enters the discharge trough 102, and then the knife roller 100 drives the orange peels to move toward the fixed knife 200, and then cuts the orange peels into blocks, while a small part of the orange peels cannot fall into the discharge trough 102 at the beginning, and this part of the orange peels may fall into another discharge trough 102 during the rotation of the knife roller 100, and then are cut into blocks by the knife roller 100 and the fixed knife 200, while a very small part is brought to the fixed knife 200 by the knife roller 100. The orange peel is resisted by the abutment surface 203 of the fixed knife 200, and as the knife roller 100 continuously applies thrust to the orange peel, the orange peel will be arched because the fresh orange peel is soft and easily deformed. The arched orange peel has a certain elastic restoring force, and the front end of the orange peel has a tendency to be inserted into the knife roller 100 under the action of the elastic restoring force. Therefore, when the front end of the orange peel is just aligned with the discharge groove 102, the front end of the orange peel will be inserted into the discharge groove 102, thereby completing the cutting of the orange peel, and the cut orange peel is located in the discharge groove 102. As the knife roller 100 rotates, the block of orange peel falls out of the discharge groove 102, thereby avoiding block materials. The orange peels are accumulated in the discharge chute 102, which affects the cutting of the material. After the orange peels are cut, the block-shaped orange peels fall into the receiving box 400 along the discharge chute 102, and the remaining orange peels are blocked by the abutment surface 203, so that the size of the block-shaped orange peels can be adjusted by adjusting the rotation speed of the knife roller 100. Similarly, the remaining orange peels fall into the discharge chute 102 under the action of gravity or arch under the rotation and push of the knife roller 100, and then enter the subsequent discharge chute 102 again. Finally, the strip-shaped orange peels are cut into several blocks. For the last orange peel, if it can fall completely into the discharge chute 102, it means that its size meets the requirements and does not need to be cut, thereby completing the cutting of the orange peels.
