[0018] The intelligent root cutting system of the box-packed sprout production line comprises a conveying line, a root cutting mechanism, a positioning assembly and a recycling assembly arranged in sequence along the conveying direction of the conveying line. The root cutting mechanism comprises a knife box assembly, a driving assembly and a limiting assembly, and the knife box assembly and the limiting assembly are arranged on the two sides of the conveying line and face each other. The knife box assembly comprises a top plate and a bottom plate which are parallel to each other, a blade is arranged at one end of the bottom plate, and a straight groove is formed in the bottom plate at positions on both sides of the blade. The driving assembly comprises a lifting mechanism, a horizontal moving mechanism and an overturning mechanism, which are used to drive the knife box assembly to lift, horizontally move and overturn, respectively. The limiting assembly comprises a vertical plate, a scraping plate and a plurality of limiting devices, the limiting device comprises a limiting cone and a spring, one end of the limiting cone is fixedly connected with the vertical plate, the other end of the limiting cone is in the form of a sharp end and faces the direction of the knife box assembly, the spring is sleeved on the limiting cone, and one end of the spring extends out of the sharp end of the limiting cone.

[0019] The production process of the intelligent root cutting system of the boxed sprout production line is: first, sprouts are cultivated in the bottom tray, after the sprouts grow, the top box is buckled and the sprout box is placed on the conveying line; then the positioning device is used to block the sprout box in front of the knife box assembly; then the lifting mechanism is used to adjust the root cutting height of the knife box assembly; then the horizontal moving mechanism is used to move the knife box assembly to the sprout box direction to complete the root cutting operation; then the lifting mechanism is used to lift the knife box assembly with the top box, so that the top box is separated from the bottom tray, the bottom tray is conveyed forward on the conveying line and then pushed away from the conveying line by the recycling assembly; then the turnover mechanism is used to turn over the knife box assembly with the top box by 180 degrees, so that the top box assumes an open upward posture; then the horizontal moving mechanism is used to retreat the knife box assembly, and the top box is scraped off on the conveying line under the action of the hanging and falling plate.

The scraping plate 32 is arranged in the vertical direction, the scraping plate 32 is fixedly connected with the vertical plate 31, and the scraping plate 32 is arranged at a position directly above the conveying line 1 on the side close to the knife box assembly 10. As shown Figure 1 、 Figure 2 As shown, the driving assembly 20 includes a lifting mechanism, a horizontal moving mechanism and a turnover mechanism, the lifting mechanism can drive the knife box assembly 10 to lift in the vertical direction, the horizontal moving mechanism can drive the knife box assembly 10 to move horizontally in the horizontal direction perpendicular to the conveying line 1, and the turnover mechanism can drive the knife box assembly 10 to turn over, and the rotation axis of the turnover action of the knife box assembly 10 is in the horizontal direction and perpendicular to the conveying direction of the conveying line 1.

[0030] As shown Figure 2 The positioning assembly 40 includes a positioning plate 41, which can extend to a position above the conveying line 1 close to the top surface of the conveying line 1 or retract to a position away from the conveying line 1. The recycling assembly 50 includes a push plate 51 and a recycling box 52, which are arranged on both sides of the conveying line 1 respectively, and the push plate 51 is used to push the materials on the conveying line 1 away from the conveying line 1 and into the recycling box 52.

[0031] The intelligent root cutting system of the boxed sprout production line is also matched with a sprout box when applied, as shown Figure 4 The sprout box includes a bottom disc 2 and a top box 3, the top box 3 is a hollow quadrilateral box structure, the bottom surface of the top box 3 is open, and the bottom surface of the top box 3 can be buckled on the top surface of the bottom disc 2. In the foregoing knife box assembly 10, there is a set height between the bottom plate 12 and the top plate 11, and a containing area is formed at the position, the size of the top box 3 of the sprout box is adapted to the size of the containing area and is also adapted to the size of the two straight grooves 13 on the bottom plate 12, specifically, the overall height of the top box 3 is greater than the distance between the bottom plate 12 and the top plate 11, the distance between the outer walls of the two ends of the top box 3 is slightly smaller than the distance between the edges of the two straight grooves 13 away from each other, and the distance between the inner walls of the two ends of the top box 3 is slightly greater than the distance between the edges of the two straight grooves 13 close to each other. The height of the bottom disc 2 is adapted to the foregoing limiting devices, the positioning plate 41 and the push plate 51, specifically, when the bottom disc 2 is placed on the conveying line 1, the front end thereof can be blocked and positioned by the positioning plate 41, the side edge thereof can face the pointed end of the limiting cone 33, and the push plate 51.

[0032] The overall working process of the intelligent root cutting system of the boxed sprout production line is as follows:

[0033] S1. Grow sprouts in a base tray 2. After the sprouts have grown, attach a top box 3 to the top of the base tray 2. Then, place the entire sprout box on a conveyor line 1 and convey it forward along the conveyor line 1. When placing the box, the side of the top box 3 must be substantially parallel to the conveying direction of the conveyor line 1. It should be noted that, in practice, the base tray 2 is a quadrilateral box structure with an open top. When growing sprouts, a seedling tray must be placed at the opening of the base tray 2. After the sprouts have grown, the sprout roots are located below the seedling tray, and the sprout products are located above the seedling tray.

[0034] S2, when the sprout box is conveyed by the conveyor line 1 to the position facing the knife box assembly 10 (this state is as follows Figure 1 As shown), the positioning assembly 40 is actuated to cause the positioning plate 41 to extend to a position close to the top surface of the conveyor line 1, thereby blocking and positioning the chassis 2.

[0035] S3: The lifting mechanism moves the knife box assembly 10 up and down, adjusting the height of the blade 14 to the root cutting height. This root cutting height refers to the height of the blade 14 when cutting roots. It is determined according to the type of sprout. It is generally located slightly above the top surface of the seedling tray, that is, at the bottom of the top box 3 near the bottom end and slightly above the top surface of the bottom plate 2. The distance between this root cutting height and the top box 3 is slightly less than the height between the bottom plate 12 and the top plate 11 of the knife box assembly 10. (In practice, the position of this root cutting height is calibrated by the through-slot hole 4 described later.)

[0036] S4, the transverse movement mechanism is actuated to cause the knife box assembly 10 to move transversely toward the vertical plate 31. During the transverse movement: on the one hand, the blade 14 first contacts the top box 3. Since the top box 3 and the chassis 2 are buckled together as one, there is a thrust on the sprout box, which can push the sprout box as a whole toward the vertical plate 31. After the side of the chassis 2 contacts the end of the spring 34, the spring 34 is gradually compressed, and at the same time, the side of the chassis 2 gradually pierces the limiting cone 33; on the other hand, the blade 14 gradually cuts into the top box 3 to complete the sprout root cutting process. According to the above, during the cutting process, the reaction force provided by the spring 34 is gradually increased as it is compressed. The cutting force of the cutting process is also a gradually changing flexible cutting process, which is beneficial to ensure the root cutting quality and avoid pressure damage to the top box 3. When completing the horizontal movement, the blade 14 passes through one side of the top box 3 to the other side, and the solid parts of the side walls at both ends of the top box 3 are respectively inserted into the two straight grooves 13 through the open ends of the two straight grooves 13. The cut sprout roots remain in the bottom plate 2, and the sprout products are located in the area between the bottom plate 12 and the closed end of the top box 3. The upper part of the top box 3 is also inserted into the accommodating area between the bottom plate 12 and the top plate 11.

[0037] S5: The lifting mechanism is activated, causing the knife box assembly 10 and the top box 3 to move upward to the set position. During the upward movement of the knife box assembly 10, the limiting cone 33 is inserted into the side wall of the chassis 2, which limits the vertical freedom of the chassis 2. The knife box assembly 10 drives the top box 3 upward, allowing the top box 3 to separate from the chassis 2. After separation, the chassis 2 is pushed back onto the conveyor line 1 under the restoring force of the spring 34.

[0038] S6, the flip mechanism is actuated, causing the knife box assembly 10 and the top box 3 to flip 180 degrees. At this time, the top box 3 is flipped to a posture where the opening is upward; at the same time, the positioning assembly 40 is actuated to retract the positioning plate 41, and the chassis 2 moves forward with the conveyor line 1 to the position of the recovery assembly 50. When the action is completed, the system structure is as follows: Figure 2 shown.

[0039] S7, the recovery component 50 is activated, and the chassis 2 is pushed out from the conveyor line 1 into the recovery box 52 for collection through the push plate 51, and then the push plate 51 is retracted.

[0040] S8, the lifting mechanism is actuated to move the knife box assembly 10 upward to a position close to the bottom end of the scraping plate 32, and the bottom end of the scraping plate 32 blocks the area above the open end of the top box 3 (the open end of the top box 3 faces upward after being flipped over in the aforementioned step S6) from extending out of the knife box assembly 10.

[0041] S9: The lateral movement mechanism moves the knife box assembly 10 laterally away from the vertical plate 31. Due to the obstruction of the drop plate 32, the top box 3 is scraped outward from the knife box assembly 10 during this lateral movement and falls onto the conveyor line 1 under its own weight. Thereafter, the top box 3 is conveyed forward along the conveyor line 1 with its opening facing upward. Subsequent product packaging can be completed directly by capping or laminating the open end of the top box 3.

[0042] The above working process is the root cutting operation process of a single sprout box. In actual production, batches of sprout boxes can be produced according to the above steps to realize assembly line operation. It can be seen from the working process that the intelligent root cutting system of the boxed sprout production line can be used for the automatic root cutting operation of this type of sprout box. Compared with the manual root cutting method, the root cutting efficiency is high and the root cutting position is accurate, which can effectively reduce the labor intensity of the operator and eliminate safety hazards. In addition, through the above process design, no other transfer links are required after the root cutting is completed. The top box 3 after root cutting is in an open-up posture. After being transported by the conveyor line 1, the product can be directly packaged by laminating or covering. The whole process is smoothly connected, which can further improve production efficiency.

[0043] Since the top box 3 is used for the outer packaging box of the final product, it is usually made of materials such as transparent plastic. Further, in the design of the sprout box, such as Figure 4As shown, a through long hole 4 is also provided on one side of the top box 3, and the two ends of the through long hole 4 are arranged near the inner walls of the two ends of the top box 3. The length of the blade 14 in the knife box assembly 10 is adapted to the length of the through long hole 4, so that the length of the blade 14 is slightly smaller than the length of the through long hole 4. When the sprout box is placed in the aforementioned step S1, the through long hole 4 is oriented toward the direction of the knife box assembly 10. In the aforementioned step S4, the root cutting operation of the sprouts is completed after the blade 14 passes through the through long hole 4. The design of the through long hole 4 is used, on the one hand, to mark the root cutting height position described in the aforementioned step S3 on the sprout box, and is also convenient for the recognition of automatic control components such as sensors and depth cameras in application, so as to ensure the accuracy of the height adjustment position of the blade 14 in the step S3; on the other hand, during the cutting process of the aforementioned step S4, the top box 3 is prevented from being squeezed and deformed by the blade 14, thereby ensuring the final packaging quality.

[0044] In the aforementioned step S4, the vertical plate 31 plays a role similar to that of an anvil. In specific implementation, a knife groove 35 is provided on the side of the vertical plate 31 close to the conveyor line 1. The knife groove 35 is adapted to the blade 14. When the root cutting is completed in the above step S4, the blade 14 faces the knife groove 35 to avoid impact, thereby protecting the blade 14.

[0045] When implementing:

[0046] like Figure 3 As shown, in the knife box assembly 10, the blade 14 has a cutting angle of 18°, which can effectively reduce the pressure on the material of the top box 3 during the root cutting operation and ensure the appearance quality of the product; a number of weight-reducing ventilation holes are provided on the bottom plate 12 to reduce the weight of the structure and keep it ventilated and dry during use, thereby extending the service life of the blade 14. The knife box assembly 10 also includes two side guards 15, both of which are fixedly connected to the top plate 11 and the bottom plate 12, so that the knife box assembly 10 as a whole has a hollow quadrilateral box structure with two ends open, so as to further provide protection and prevent the top box 3 from falling out of the knife box assembly 10 during the flipping process of the aforementioned step S6; a number of protective seams are provided on the side guards 15, which not only reduce the weight of the structure but also reduce the wear of the product outer packaging caused by excessive contact between the side guards 15 and the side of the top box 3 during the root cutting process.

[0047] like Figure 2As shown, in the driving assembly 20, the lifting mechanism comprises a lifting motor 21, a lifting screw rod 22, a support 23 and a sliding seat 24, the transverse moving mechanism selects an electric push rod 25, and the overturning mechanism selects a speed reducer motor 26. The support 23 is fixedly arranged at one end of the cutter box assembly 10 away from the conveying line 1, the lifting screw rod 22 is rotatably connected with the support 23, the sliding seat 24 is slidingly connected with the support 23, the sliding seat 24 is threadedly connected with the lifting screw rod 22, and the lifting motor 21 is used for driving the lifting screw rod 22 to rotate. The electric push rod 25 is fixedly installed on the sliding seat 24, the extending end of the electric push rod 25 is fixedly connected with the speed reducer motor 26, and the output end of the speed reducer motor 26 is fixedly connected with the cutter box assembly 10. Therefore, the driving of the overturning action of the cutter box assembly 10 can be realized through the speed reducer motor 26, the speed reducer motor 26 can be driven to move transversely through the extension and retraction of the electric push rod 25, the driving of the transverse moving action of the cutter box assembly 10 is further realized, the lifting mechanism constitutes a screw rod and nut mechanism, the lifting motor 21 can be used for accurately controlling the lifting action of the sliding seat 24, and the driving and accurate control of the lifting action of the cutter box assembly 10 are further realized.

[0048] As shown in Figure 2 The positioning assembly 40 further comprises an electric push rod A42, the electric push rod A42 is fixedly arranged at one side of the conveying line 1, the extending end of the electric push rod A42 is fixedly connected with the positioning plate 41, and the extension and retraction action of the electric push rod A42 can drive the positioning plate 41 to extend to a position close to above the conveying line 1 or to retreat back.

[0049] As shown in Figure 2 The recycling assembly 50 further comprises an electric push rod B53, the electric push rod B53 is fixedly arranged at one side of the conveying line 1, the extending end of the electric push rod B53 is fixedly connected with the push plate 51, the extension and retraction action of the electric push rod B53 can drive the push plate 51 to extend or retreat back, the push plate 51 can push the materials into the recycling box 52 when the push plate 51 extends to above the conveying line 1, and the push plate 51 can be away from the position of the conveying line 1 to avoid blocking the conveying of the materials on the conveying line 1 when the push plate 51 retreats back.
