[0002] The leaves of leafy vegetables are mostly green or dark in color, and the roots are mostly white or light in color. When eating, the leaves or stems connected to the leaves are mostly eaten, and in most cases the roots of leafy vegetables need to be discarded. Therefore, during the processing of leafy vegetables, the roots need to be removed, and then the stems and leaves are cut into strips and blocks for convenient packaging.

[0003] The existing method for processing leafy vegetables is manual screening and cutting, that is, the washed leafy vegetables are first manually picked up, the roots are cut off with a knife, and then the next process is entered. The operator in the next process cuts the stems and leaves with a knife to form strips or blocks, and finally the stems and leaves in the form of strips or blocks are packaged. The above process can meet the cutting and processing requirements of leafy vegetables, but a large amount of manual labor is required, which not only reduces work efficiency but also wastes a lot of labor. In addition, it can only meet the processing needs of small-scale production. In addition, when cutting by hand, the width and length of the strips and blocks are only determined by the feeling of the operator, and there is a large difference in size, which is not conducive to subsequent packaging. In addition, the existing knives for cutting off the roots and cutting the strips and blocks are conventional blades on the market, so that the cut surface of the vegetables exposed to the air during cutting, which not only easily causes water and nutrient loss, but also easily infects bacteria and causes browning, which is not conducive to the preservation of vegetables.

Embodiment

[0035] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the following embodiments are combined with the accompanying drawings to Figure 1 to Figure 8 The technical solutions provided by the present application are described in detail, but the following content is not a limitation of the present application.

[0036] Figure 1 Structure diagram of a state of an embodiment of the fresh-cut vegetable cutting device and use method of the present application; Figure 2 Structure diagram of another state of an embodiment of the fresh-cut vegetable cutting device and use method of the present application. As shown in Figure 1 and Figure 2 The fresh-cut vegetable cutting device and use method provided by the present embodiment include: a state discrimination and arrangement module 1, a cutting module 2, a glue supplying component 22, and a root removing module 3.

[0037] Specifically, the state discrimination and arrangement module 1 includes a discrimination component 11 and an arrangement component 12. At this time, the discrimination component 11 is arranged beside the arrangement component 12, and the discrimination component 11 has a visual camera 111, while the arrangement component 12 has a conveying belt 121 that transports the leafy vegetables to be processed. The visual camera 111 is installed upstream of the conveying belt 121 in the conveying direction of the conveying belt 121, and the shooting range of the visual camera 111 covers the width direction of the conveying belt 121, so that the visual camera 111 can shoot the leafy vegetables at the corresponding position when the leafy vegetables are transported by the conveying belt 121. The color depth of the leafy vegetables is determined to determine the root direction, which provides conditions for subsequent direction adjustment of the vegetables with reversed root and leaf directions, and facilitates subsequent removal of the roots of the leafy vegetables. It should be pointed out that the visual camera 111 is a device commonly used in the traditional image recognition industry on the market, and the direction determination according to the color depth is a conventional technical means in the industry, so its specific structure and working principle will not be described here, and it can meet the recognition requirements.

[0038] Specifically, the cutting module 2 further includes a cutter component 21 and a glue supply component 22. At this time, a first cutting table 23 is arranged below the cutter component 21, and the downstream of the conveying belt 121 extends to the first cutting table 23, that is, the leafy vegetables transported by the conveying belt 121 are transferred to the first cutting table 23. At the same time, the cutter component 21 moves up and down in the vertical direction, that is, when the cutter component 21 moves up and down, the leafy vegetables on the first cutting table 23 are cut into strips or pieces, realizing the cutting of the leafy vegetables. Compared with manual cutting, not only the cutting efficiency is improved, but also time and labor are saved, and manual waste is avoided. At the same time, the size difference between each piece or strip can also be reduced, which is beneficial to subsequent packaging and meets the needs of large-scale production and manufacturing. At the same time, the cutter component 21 is also connected with the glue supply component 22, and the glue supply component 22 stores protective gel 221. The glue supply component 22 continuously supplies protective gel 221 to the cutter component 21, so that the protective gel 221 can be applied to the cut surface of the vegetables generated by the cutter component 21 when the cutter component 21 cuts the leafy vegetables. A protective layer is formed on the cut surface of the vegetables by the protective gel 221, which can lock in moisture and nutrients, prevent browning caused by infection of pathogenic bacteria, and realize preservation of the vegetables.

[0039] More specifically, the sorting assembly 12 in the state identification and sorting module 1 further comprises a turning assembly 122, a first pushing assembly 123 and a second pushing assembly 124. The turning assembly 122 is arranged at one side of the middle of the conveying belt 121, i.e. after the visual camera 111 determines that the root-leaf direction of the vegetable is reversed, the vegetable can subsequently enter the turning assembly 122, and the turning assembly 122 is used to turn the vegetable around. Meanwhile, the side of the conveying belt 121 away from the turning assembly 122 is provided with the first pushing assembly 123 which reciprocates towards the side of the turning assembly 122, i.e. when the visual camera 111 determines that the root-leaf direction of the current vegetable is reversed, the first pushing assembly 123 pushes the vegetable from the conveying belt 121 into the turning assembly 122, and the vegetable is turned around by the turning assembly 122. Meanwhile, the side of the turning assembly 122 away from the conveying belt 121 is provided with the second pushing assembly 124 which reciprocates towards the side of the conveying belt 121, so that the vegetable after turning can be pushed by the second pushing assembly 124 from the turning assembly 122 back to the conveying belt 121, facilitating the subsequent cutting of the root of the vegetable. It is worth pointing out that the first pushing assembly 123 and the second pushing assembly 124 are preferably telescopic air cylinders, which are quick in action and low in cost.

[0040] More specifically, the turning assembly 122 of the arranging assembly 12 further comprises a conveying side path and a rotating disc 1225, at this time, the conveying side path comprises a first conveying belt 1221, a second conveying belt 1222, a third conveying belt 1223 and a fourth conveying belt 1224, the first conveying belt 1221 and the fourth conveying belt 1224 are both arranged along the transverse direction of the conveying belt 121 and are both arranged on the same side of the conveying belt 121, the second conveying belt 1222 and the third conveying belt 1223 are both arranged along the conveying direction of the conveying belt 121 and are located on the same straight line, and one end of the second conveying belt 1222 extends to one end of the first conveying belt 1221 away from the conveying belt 121, the third conveying belt 1223 extends to one end of the fourth conveying belt 1224 away from the conveying belt 121, the rotating disc 1225 is located between the second conveying belt 1222 and the third conveying belt 1223, at the same time, a first pushing assembly 123 is arranged along the conveying direction of the first conveying belt 1221, and a second pushing assembly 124 is arranged along the conveying direction of the fourth conveying belt 1224, so that the first pushing assembly 123 pushes the vegetables with the roots reversed from the conveying belt 121 to the first conveying belt 1221, and then conveys the vegetables to the second conveying belt 1222 through the first conveying belt 1221, and then transfers the vegetables to the rotating disc 1225 through the second conveying belt 1222, and then rotates 180 degrees through the rotating disc 1225 to realize the turning of the vegetables, at this time, the bottom of the rotating disc 1225 is provided with an inclined assembly, that is, one side of the rotating disc 1225 is hinged to the driving shaft of the rotating driver, and the driving shaft of the rotating driver and the other side of the bottom of the rotating disc 1225 are provided with a telescopic cylinder, that is, when the telescopic cylinder is extended, the rotating disc 1225 is inclined, so that the vegetables on the rotating disc 1225 can fall onto the third conveying belt 1223, and then the vegetables are transported to the fourth conveying belt 1224 through the third conveying belt 1223, and finally the vegetables on the fourth conveying belt 1224 are pushed back to the conveying belt 121 through the second pushing assembly 124 to continue the conveying through the conveying belt 121.

[0041] More specifically, a root removing module 3 is further arranged between the downstream end of the conveying belt 121 and the first cutting table 23, at this time, the root removing module 3 further comprises a second cutting table 31 and a root cutting assembly 32, the second cutting table 31 is arranged downstream of the conveying belt 121, so that the vegetables conveyed by the conveying belt 121 can be transferred to the second cutting table 31, and the root cutting assembly 32 is arranged above the second cutting table 31 and moves up and down along the vertical direction, and the roots of the vegetables on the second cutting table 31 are cut off through the up and down movement of the root cutting assembly 32. In addition, a gap is arranged between the second cutting table 31 and the first cutting table 23, so that the small roots cut off in the subsequent transfer between the second cutting table 31 and the first cutting table 23 can fall from the gap between the first cutting table 23 and the second cutting table 31, and the stem and leaf parts with larger volume are transferred to the first cutting table 23.

[0042] Figure 3 is a structural diagram of the first cutting station of a preferred embodiment of the present application. As shown in Figure 1 , Figure 2 and Figure 3 , the first cutting station 23 and the second cutting station 31 both include a polygonal roller 231, a strip-shaped steel belt 232 and a cutting station driver, at this time, the polygonal roller 231 is provided with two groups, the two groups of polygonal rollers 231 are arranged in parallel and are spaced apart, forming two rolling groups, and one group of polygonal rollers 231 is power-connected with the cutting station driver, that is, one group of polygonal rollers 231 is driven to rotate by the cutting station driver, providing conditions for the movement of the subsequent strip-shaped steel belt 232. At the same time, the strip-shaped steel belt 232 is an annular structure formed after the side parts of a plurality of strip-shaped steel plates are hingedly connected with each other, ensuring the structural strength of the strip-shaped steel belt 232 and providing conditions for the cutting knife assembly 21 and the root cutting assembly 32 to directly cut off the vegetables on the strip-shaped steel belt 232. Moreover, the strip-shaped steel belt 232 is wound on the two groups of polygonal rollers 231, and in the part where the strip-shaped steel belt 232 contacts the polygonal roller 231, each strip-shaped steel plate is attached to an edge, which can not only prevent the strip-shaped steel belt 232 from slipping on the polygonal roller 231, but also adapt to the width of each strip-shaped steel plate in the strip-shaped steel belt 232, ensuring that the strip-shaped steel belt 232 has a larger supporting area, facilitating the cutting operation of the vegetables. Preferably, the first cutting station 23 and the second cutting station 31 both further include a plurality of supporting wheels 233, at this time, the plurality of supporting wheels 233 are arranged between the two groups of polygonal rollers 231 and contact the bottom surface of the upper layer of the strip-shaped steel belt 232. Since the upper layer of the strip-shaped steel belt 232 will be subsequently matched with the cutting knife assembly 21 and the root cutting assembly 32 to complete the cutting operation of the vegetables, the structural stability of the upper layer of the strip-shaped steel belt 232 can be further improved by the plurality of supporting wheels 233, and the cutting effect is better.

[0043] More specifically, the root cutting assembly 32 in the root removing module 3 further includes a root cutting support 321, a root cutting driver 322 and a root cutting blade 323, at this time, the root cutting support 321 is fixedly installed on the side edge of the second cutting station 31, the upper end of the root cutting support 321 extends above the second cutting station 31, the root cutting driver 322 is installed on the upper end of the root cutting support 321, the root cutting driver 322 is arranged towards the second cutting station 31, and the root cutting blade 323 is installed on the driving shaft of the root cutting driver 322, that is, when the root cutting driver 322 moves up and down in the vertical direction, the root cutting blade 323 can also move up and down in the vertical direction, thereby moving away from or approaching the second cutting station 31, so as to realize the cutting of the roots of the vegetables on the second cutting station 31.

[0044] Figure 4 is a structural diagram of the cutting knife assembly of a preferred embodiment of the present application. As shown in Figure 1 , Figure 2 and Figure 4As shown, the cutting assembly 21 in the cutting module 2 includes a cutting bracket, a cutting driver 211, a cutting mounting bracket 212, several horizontal blades 213, and several vertical blades 214. At this time, the cutting bracket is fixedly installed on the side of the first cutting table 23 and its upper end extends above the first cutting table 23. At the same time, the cutting driver 211 is installed vertically on the upper end of the cutting bracket, and the drive shaft of the cutting driver 211 is arranged facing the first cutting table 23. Meanwhile, the cutting mounting bracket 212 is installed on the cutting driver 211. The cutting mounting bracket 212 expands the installation area of ​​the end of the drive shaft of the cutting driver 211, providing conditions for the subsequent installation of several vertical blades 214. At this time, several vertical blades 214 are arranged parallel and spaced along the conveying direction of the conveyor belt 121 on the cutter mounting frame 212, and several horizontal blades 213 are arranged perpendicular to the vertical blades 214 and are installed parallel and spaced on the vertical blades, so that the vertical blades 214 and the horizontal blades 213 form several "well" shaped structures, which provides conditions for subsequent cutting of vegetables. That is, when the cutter driver 211 moves up and down in the vertical direction, the drive shaft of the cutter driver 211 drives the cutter mounting frame 212 to move up and down in the vertical direction, so that the vertical blades 214 and the horizontal blades 213 can contact or move away from the first cutting table 23, realizing the cutting operation of vegetables on the first cutting table 23. The structural design is more reasonable.

[0045] Additionally, the cutter mounting bracket 212 is rotatably mounted on the cutter driver 211, allowing the cutter mounting bracket 212 to rotate on the drive shaft of the cutter driver 211. A limit assembly is provided between the cutter mounting bracket 212 and the cutter driver 211. This limit assembly includes a limit bracket and a limit pin. Furthermore, two limit holes are radially formed on the drive shaft of the cutter driver 211, and these two limit holes are distributed at a 90-degree angle to each other circumferentially on the drive shaft of the cutter driver 211. On the cutter mounting bracket 212, a locking hole is provided on the limiting bracket. The limiting pin is inserted into the locking hole and selectively threaded to one of the limiting holes. That is, when the limiting pin is connected to one of the limiting holes, the current state of the cutter mounting bracket 212 can be maintained. When the limiting pin is loosened and then connected to the other limiting hole, the cutter mounting bracket 212 needs to be rotated 90 degrees so that the arrangement direction of the vertical blade 214 and / or the horizontal blade 213 is reversed, which provides the conditions for converting the block cutting mode into the strip cutting mode.

(See diagram below.) Figure 4 , Figure 5 , Figure 6And Figure 7 As shown, the bottom edge of the horizontal knife 213 is provided with a plurality of clamping grooves 2131 along the length direction, and the plurality of clamping grooves 2131 are arranged at intervals on the horizontal knife 213, and when the horizontal knife 213 is installed on the vertical knife 214, the plurality of vertical knives 214 are clamped into the plurality of clamping grooves 2131 respectively, which not only ensures the stability of the installation of the horizontal knife 213 on the vertical knife 214, but also maintains the bottom edge of the horizontal knife 213 flush with the bottom edge of the vertical knife 214, thereby ensuring the cutting effect. In addition, at least one clamping groove 2131 is provided with a locking groove 2132 penetrating through the horizontal knife 213, and the side of the vertical knife 214 corresponding to the clamping groove 2131 with the locking groove 2132 is selectively provided with a limiting strip 2141 extending into the locking groove 2132, that is, when the horizontal knife 213 is installed on the vertical knife 214, the clamping groove 2131 of the horizontal knife 213 can be clamped on the vertical knife 214 first, which facilitates the installation of the horizontal knife 213 on the vertical knife 214, and then the limiting strip 2141 is inserted into the locking groove 2132 and fixed to the side of the vertical knife 214 through screws or other structures, thereby achieving the fixed installation of the limiting strip 2141 on the vertical knife 214. In addition, the top knife back of the horizontal knife 213 is provided with a guide rail 2133 along the length direction, and a sliding block 2134 is slidably arranged on the guide rail 2133, and a locking screw 2135 is arranged on the sliding block 2134, and the lower end of the locking screw 2135 extends to the locking groove 2132 and is arranged on a locking hook 2136. After the horizontal knife 213 is installed on the vertical knife 214, the sliding block 2134 is moved, so that the locking hook 2136 at the lower end of the locking screw 2135 can be moved below the limiting strip 2141 and hooked on the limiting strip 2141, and after the locking hook 2136 is hooked on the limiting strip 2141, the operator tightens the locking screw 2135, so that the locking hook 2136 is pressed on the limiting strip 2141 through the locking screw 2135, thereby stably fixing the horizontal knife 213 on the vertical knife 214, thereby preventing the horizontal knife 213 from moving upward and falling off the vertical knife 214 during cutting, ensuring the stability of the installation of the horizontal knife 213. In addition, the structure of the guide rail 2133, the sliding block 2134 and the locking screw 2135 can avoid each other when the horizontal knife 213 is initially installed on the vertical knife 214, which facilitates the installation and is more reasonable in structure design.

Figures 5 to 8As shown, the glue applying structure 215 is arranged on each horizontal knife 213 and vertical knife 214, at this time, the glue applying structure 215 further comprises a glue supply joint 2151, a baffle 2152 and an elastic sheet 2153, meanwhile, an inner recessed glue storage groove 2155 is arranged on the side surface of each horizontal knife 213 and vertical knife 214, and the lower end of the glue storage groove 2155 extends to the knife edge, meanwhile, the glue supply joint 2151 which is connected with the glue supply assembly 22 is arranged on the end of each horizontal knife 213 and vertical knife 214, so that the protective gel 221 in the glue supply assembly 22 can enter into the glue storage groove 2155 through the glue supply joint 2151, meanwhile, the baffle 2152 is arranged on the outer side groove of the glue storage groove 2155 and covers the corresponding outer side groove, and the baffle 2152 prevents the protective gel 221 in the glue storage groove 2155 from excessive leakage. Meanwhile, the lower end of the baffle 2152 is movably inserted into the glue storage groove 2155, and the elastic sheet 2153 is installed on the upper end of the baffle 2152, and the elastic sheet 2153 is installed on the upper end of the glue storage groove 2155, that is, when the horizontal knife 213 and / or vertical knife 214 cuts the vegetable, the cutting surface of the vegetable will extrude the baffle 2152, so that the baffle 2152 moves towards the glue storage groove 2155, meanwhile, a plurality of mesh holes 2154 are arranged on the baffle 2152, and the protective gel 221 in the glue storage groove 2155 is extruded out of the mesh holes 2154 and onto the cutting surface of the vegetable, and when the vertical knife 214 and / or horizontal knife 213 is subsequently separated, the protective gel 221 can be applied on the cutting surface of the vegetable, so as to form a protective layer on the cutting surface of the vegetable. In addition, the groove along the upper end of the lower end of each glue storage groove 2155 near the knife edge is provided with a limiting baffle which protrudes into the groove, and the lower end of the baffle 2152 is blocked by the limiting baffle, preventing the lower end of the baffle 2152 from being pulled out of the glue storage groove 2155, in addition, the baffle 2152 and the elastic sheet 2153 are of an integrated structure, and the structural strength is higher. Moreover, the baffle 2152 is of a bending structure, and the middle part of the baffle 2152 protrudes outward of the lower end of the baffle 2152, so that when the vertical knife 214 and / or horizontal knife 213 assembly is lowered, the cutting surface of the vegetable can better contact the baffle 2152 without being blocked by the vertical knife 214 and / or horizontal knife 213 itself, thereby ensuring that the baffle 2152 can be smoothly extruded, and the structural design is more reasonable. It is worth pointing out that since the horizontal knife 213 is provided with a plurality of clamping grooves 2131, at this time, each of the regions formed by the clamping grooves 2131 on the horizontal knife 213 corresponds to a glue applying structure 215, and the upper end of the horizontal knife 213 is provided with a glue guiding channel which communicates with each glue storage groove 2155, and the glue supply joint 2151 communicates with the glue guiding channel, so as to ensure that when the horizontal knife 213 cuts the vegetable, the cutting surface of the vegetable can also be applied with the protective layer, and the structural design is more reasonable.

[0048] More specifically, the protective gel 221 stored in the glue supply assembly 22 is prepared by electrolyzing 2-5% NaCl and inorganic acid to generate 20-50ppm electrolytic water, and then mixing and stirring the electrolytic water with 1-3% gelatinizer (such as magnesium lithium silicate) to form a gel. The protective gel 221 has better sterilization effect, can effectively isolate oxygen, improve the anti-browning effect, better realize water locking, and prevent nutrient loss.
