DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0018] like Figures 1 to 5 As shown, an intelligent root cutting system for a boxed sprout production line includes a conveyor line 1, along the conveying direction of the conveyor line 1 are sequentially provided with a root cutting mechanism, a positioning component 40 and a recovery component 50.

[0019] The root cutting mechanism includes a knife box assembly 10, a driving assembly 20 and a limit assembly 30. The knife box assembly 10 and the limit assembly 30 are respectively arranged on both sides of the conveyor line and are arranged opposite to each other. Figure 3 As shown, the knife box assembly 10 includes a top plate 11 and a bottom plate 12. The top plate 11 and the bottom plate 12 are parallel to each other and fixedly connected. Two parallel straight grooves 13 are provided on the bottom plate 12. The straight grooves 13 are open at least at one end. The area between the two straight grooves 13 forms a blade portion. A blade edge 14 is provided at one end of the blade portion. The end of the straight groove 13 close to the blade edge 14 is an open end. The blade edge 14 is provided at one end of the knife box assembly 10 close to the conveying line 1 and is parallel to the conveying direction of the conveying line 1. Figure 2 , Figure 5 As shown, the limiting assembly 30 includes a vertical plate 31, a scraper plate 32 and a plurality of limiting devices, and the limiting device includes a limiting cone 33 and a spring 34. One end of the limiting cone 33 is fixedly connected to the vertical plate 31, and the other end of the limiting cone 33 is pointed and is arranged in the direction of the knife box assembly 10. The spring 34 is sleeved on the limiting cone 33, one end of the spring 34 is connected to the vertical plate 31, and the other end of the spring 34 extends out of the tip of the limiting cone 31, and the setting height of the limiting cone 31 is between the conveyor line 1 and the blade 14. The scraper plate 32 is arranged in the vertical direction, and the scraper plate 32 is fixedly connected to the vertical plate 31. The scraper plate 32 is arranged at a position directly above the conveyor 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 transverse movement mechanism and a flipping mechanism. The lifting mechanism can drive the knife box assembly 10 to lift and lower in the vertical direction, the transverse movement mechanism can drive the knife box assembly 10 to move horizontally in a horizontal direction perpendicular to the conveying line 1, and the flipping mechanism can drive the knife box assembly 10 to flip. The rotating axis of the flipping action of the knife box assembly 10 is along the horizontal direction and perpendicular to the conveying direction of the conveying line 1.

[0020] like Figure 2 As shown, the positioning assembly 40 includes a positioning plate 41, which can be extended to a position above the conveyor line 1 close to the top surface of the conveyor line 1 or retracted to a position away from the conveyor line 1. The recovery assembly 50 includes a push plate 51 and a recovery box 52, which are respectively arranged on both sides of the conveyor line 1. The push plate 51 is used to push the material on the conveyor line 1 away from the conveyor line 1 and into the recovery box 52.

[0021] When the intelligent root cutting system of the boxed sprout production line is used, it is also equipped with a sprout box, such as Figure 4 As shown, the sprout box includes a bottom plate 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 plate 2. In the aforementioned knife box assembly 10, there is a set height between the bottom plate 12 and the top plate 11, and a receiving area is formed at this position. The size of the top box 3 of the sprout box is adapted to the size of the receiving area and 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 at both ends of the top box 3 is slightly smaller than the distance between the sides of the two straight grooves 13 that are far away from each other, and the distance between the inner walls at both ends of the top box 3 is slightly greater than the distance between the sides of the two straight grooves 13 that are close to each other. The height of the chassis 2 is compatible with the aforementioned limiting device, positioning plate 41 and push plate 51. Specifically, when the chassis 2 is placed on the conveyor line 1, its front end can be blocked and positioned by the positioning plate 41, and its side can face the tip of the limiting cone 33 and the push plate 51.

[0022] The overall working process of the intelligent root cutting system of the boxed sprout production line is as follows: S1. Grow sprouts in the chassis 2. After the sprouts have grown, buckle the top box 3 on the top of the chassis 2. Then place the sprout box as a whole on the conveyor line 1 and convey it forward along the conveyor line 1. When placing, the side of the top box 3 should be basically parallel to the conveying direction of the conveyor line 1. It should be noted that during implementation, the chassis 2 is a quadrilateral box structure with an open top. When cultivating sprouts, a seedling tray needs to be placed at the opening of the chassis 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.

[0023] 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 Figure 1As shown in the figure), 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.

[0024] S3, the lifting mechanism moves the knife box assembly 10 up and down, and adjusts the height of the blade 14 to the root cutting height. The root cutting height refers to the height of the blade 14 when cutting roots, which is defined according to the sprout variety. 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. At the same time, the distance between the root cutting height and the top box 3 is slightly smaller than the height between the bottom plate 12 and the top plate 11 in the knife box assembly 10 (in practice, the position of the root cutting height is calibrated by the through long hole 4 described later).

[0025] S4, the transverse movement mechanism is actuated to cause the knife box assembly 10 to transversely move 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 to move 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 the top box 3 from being damaged by pressure. When completing the lateral movement, the blade 14 penetrates from 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, and the cut sprout roots are retained 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, and 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.

[0026] S5, the lifting mechanism is activated to move the knife box assembly 10 and the top box 3 upward to the set position. During the rising process of the knife box assembly 10, the limiting cone 33 is inserted into the side wall of the chassis 2 to limit the vertical freedom of the chassis 2. The knife box assembly 10 drives the top box 3 to rise and separate the top box 3 from the chassis 2; after the separation is completed, the chassis 2 is pushed back to the conveyor line 1 under the restoring elastic force of the spring 34.

[0027] S6, the flipping mechanism is actuated, so that the knife box assembly 10 and the top box 3 are flipped 180°, and the top box 3 is flipped to a posture with the opening facing 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.

[0028] 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.

[0029] S8, the lifting mechanism is actuated to move the knife box assembly 10 upward to a position close to the bottom end of the scraper plate 32, and the bottom end of the scraper plate 32 blocks the area above the opening end of the top box 3 (the opening 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.

[0030] S9, the transverse movement mechanism moves the knife box assembly 10 transversely away from the vertical plate 31. Due to the obstruction of the hanging plate 32, the top box 3 is scraped out of the knife box assembly 10 during the transverse movement, and falls on the conveyor line 1 under the action of its own weight. After that, the top box 3 is conveyed forward along the conveyor line 1 with the opening facing upward, and the subsequent product packaging process can be directly completed by capping or laminating the open end of the top box 3.

[0031] The above working process is the root cutting 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 boxes. Compared with the transmission manual root cutting method, the root cutting efficiency is high and the root cutting position is precise, which can effectively reduce the labor intensity of operators and eliminate safety hazards. In addition, through the above process design, no other transportation links are required after the root cutting is completed. The top box 3 after root cutting is in an open upward posture. After being transported by the conveyor line 1, the product can be directly packaged by laminating or covering. The entire process is smoothly connected, which can further improve production efficiency.

[0032] Since the top box 3 is used as the outer packaging box of the final product, it is usually made of transparent plastic or other materials. Further, in the design of the sprout box, such as Figure 4 As 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 close to 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 placing the sprout box in the aforementioned step S1, the through long hole 4 is directed toward the direction of the knife box assembly 10, and the root cutting operation of the sprouts is completed after the blade 14 passes through the through long hole 4 in the aforementioned step S4. The design of the through long hole 4 is used 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 the application, so as to ensure the accurate position of the height adjustment of the blade 14 in the step S3; on the other hand, in 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.

[0033] In the aforementioned step S4, the vertical board 31 plays a role similar to that of a chopping board. In the specific implementation, a knife groove 35 is provided on the side of the vertical board 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.

[0034] When implementing: 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, keep it ventilated and dry during use, and extend the service life of the blade 14. The knife box assembly 10 also includes two side guard plates 15, which are fixedly connected to the top plate 11 and the bottom plate 12 so that the knife box assembly 10 as a whole is a hollow quadrilateral box body structure with two ends open, so as to further form protection and prevent the top box 3 from falling off from the knife box assembly 10 during the flipping process of the aforementioned step S6; a number of protective seams are provided on the side guard plates 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 guard plates 15 and the side of the top box 3 during the root cutting process.

[0035] like Figure 2 As shown, in the driving assembly 20, the lifting mechanism includes a lifting motor 21, a lifting screw 22, a support 23 and a slide 24, the lateral movement mechanism uses an electric push rod 25, and the flip mechanism uses a reduction motor 26. The support 23 is fixedly arranged at one end of the knife box assembly 10 away from the conveyor line 1, the lifting screw 22 is rotatably connected to the support 23, the slide 24 is slidably connected to the support 23, the slide 24 is threadedly connected to the lifting screw 22, and the lifting motor 21 is used to drive the lifting screw 22 to rotate; the electric push rod 25 is fixedly installed on the slide 24, and the extended end of the electric push rod 25 is fixedly connected to the reduction motor 26; the output end of the reduction motor 26 is fixedly connected to the knife box assembly 10. Therefore, the flipping action of the knife box assembly 10 can be driven by the reduction motor 26; the reduction motor 26 can be driven to move horizontally when the electric push rod 25 is extended or retracted, thereby further driving the horizontal movement of the knife box assembly 10; the lifting mechanism constitutes a screw-nut mechanism, and the lifting action of the slide 24 can be accurately controlled by the lifting motor 21, thereby further driving and accurately controlling the lifting action of the knife box assembly 10.

[0036] like Figure 2 As shown, the positioning assembly 40 also includes an electric push rod A42, which is fixedly arranged on one side of the conveyor line 1. The extended end of the electric push rod A42 is fixedly connected to the positioning plate 41. The telescopic action of the electric push rod A42 can drive the positioning plate 41 to extend to a position close to the top of the conveyor line 1 or retract.

[0037] like Figure 2As shown, the recovery component 50 also includes an electric push rod B53, which is fixedly arranged on one side of the conveyor line 1. The protruding end of the electric push rod B53 is fixedly connected to the push plate 51. The telescopic action of the electric push rod B53 can drive the push plate 51 to extend or retract. When the push plate 51 is extended to the top of the conveyor line 1, the material can be pushed into the recovery box 52. When the push plate 51 is retracted, it can be away from the conveyor line 1 to avoid blocking the transportation of materials on the conveyor line 1.

[0038] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art shall not deviate from the spirit and scope of the present invention, and shall be within the scope of protection of the claims attached to the present invention.
