[0014] A method for using a fresh platycodon grandiflorum cleaning and fresh-keeping packaging device comprises the following steps:

[0015] S1: The fresh platycodon grandiflorum is firstly cleaned and dried by a cleaning and drying device; the dried platycodon grandiflorum is then transported to a bagging device through a conveyor line for vacuum bagging and sealing; the bagged platycodon grandiflorum is transported to a boxing device through a conveyor line for quantitative boxing; and the collection box filled with platycodon grandiflorum is then transported to a conveying rack of a box closing and packaging device;

[0016] S2: Move the collection box to the inner side of the support frame through the conveying roller on the conveying frame. At this time, the rotating ring will rotate under the driving action of the driving motor, and the rotating ring will synchronously drive the stop block to rotate. The stop block first contacts the outer wall of the first force-bearing rod, giving the first force-bearing rod an upward thrust, so that the first force-bearing rod moves upward along the inner wall of the support frame. The upward-moving first force-bearing rod will contact the outward-expanding cover of the collection box, giving the cover on the collection box an upward thrust. When the distance of the first force-bearing rod exceeds the rotation axis of the cover, the cover on the collection box will remain in a vertical state;

[0017] S3: After the operation of S2, the collection box continues to move on the conveying roller of the conveying frame, the vertical cover on the moving collection box will approach the rotating rod, and the rack will continue to move upward under the action of the first force-bearing rod. At this time, the rack will give the spur gear a rotational thrust, and the rotating spur gear drives the first bevel gear to rotate synchronously, so that the first bevel gear engages and drives the second bevel gear and the rotating rod arranged above it to rotate synchronously. Since the position of the rotating rod is located at the rotation position of the cover of the collection box, the rotating rotating rod will give the cover on the collection box a rotational thrust, so that the cover closes the collection box. At this time, the collection box continues to move forward under the action of the conveying frame;

[0018] S4: The initial state of the sealing roll is that the sealing tape at one end extends downward and droops freely, and its drooping edge is lower than the height of the collecting box after the cover is closed; when the collecting box is about to move to the bottom of the sealing roller, and the front end of the collecting box blocks the detection signal of the first infrared detector, the first air valve controls the air pipe to connect with the high-pressure air source, and at the same time allows the high-pressure airflow to be ejected outward through the first hollow cavity and the first high-pressure jet hole, which can blow the drooping end of the sealing tape of the sealing roll and fit it to the outer side wall of the front end box body of the collecting box; as the collecting box continues to move on the conveying rack, the sealing tape is pulled along the upper cover closure docking line for pasting, and during this process, the collecting box sequentially blocks the detection signal of the second infrared detector;

[0019] S5: When the collection box moves to the end where it no longer blocks the detection signal of the second infrared detector, the rotating ring moves to the highest point and rotates downward to contact the outer wall of the second force-bearing rod, thereby giving the second force-bearing rod a thrust to move downward, so that the second force-bearing rod moves downward along the outer wall of the second positioning rod and gives the second spring extrusion force, and the moving second force-bearing rod synchronously drives the cutter to move and contact the sealing tape at the end of the collection box to cut the sealing tape; after the cutting is completed, the second air valve controls the air pipe to be connected to the high-pressure air source, and at the same time allows the high-pressure airflow to be ejected outward through the second hollow air cavity and the second high-pressure jet hole, which can blow the protruding end of the sealing tape that has been cut off from the sealing roll and adhered to the collection box and fit it to the outer wall of the terminal box body of the collection box, thereby completing the automatic packaging operation.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] By setting up a sealing mechanism and a cutting mechanism, in the process of conveying the collection box through the conveying roller, the first force-bearing rod is intermittently given an upward thrust and the second force-bearing rod is intermittently given a downward thrust through the rotation of the rotating ring, so that the first force-bearing rod guides the lids on both sides of the collection box to a vertical state, and then the lids are in a flush capping docking state through the rotating rod, and then the closed lids are sealed by the sealing belt on the sealing roller, and the second force-bearing rod moves to drive the cutter to move downward to cut the sealing belt, completing the automatic packaging operation of the collection box. The device can significantly improve the production efficiency of packaging operations, save labor, and ensure packaging quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Please refer to Figure 1-Figure 6 The outer wall of the first force-bearing rod 404 is an overall "T"-shaped structure, and the inner wall of the support frame 3 is formed with a slide groove for the first force-bearing rod 404 to move vertically. The ends of the rotating rod 409 in the inactive state are located on both sides of the cover of the collection box 2 that remains in a vertical state, and the height of the rotating rod 409 is flush with the height of the collection box 2.

[0037] In this embodiment: through this structure, when the first force-bearing rod 404 is forced to move upward, the "T"-shaped first force-bearing rod 404 will first contact the cover on the collection box 2 before the collection box 2 enters the inner side of the support frame 3, giving the cover a rotational force to move upward.

[0038] Please refer to Figure 1-Figure 7 , one end of the stop block 403 extends to one side of the support frame 3, and the stop block 403 can contact the lower bottom surface of the first force-bearing rod 404 and lift it to the upper limit position during the process of rotating from bottom to top, that is, after the first force-bearing rod 404 moves from the shaded area A in the figure to the shaded area B, the stop block 403 is separated from the first force-bearing rod 404; the stop block 403 can contact the upper top surface of the second force-bearing rod 503 and press it down to the lower limit position during the process of rotating from top to bottom, that is, after the second force-bearing rod 503 moves from the shaded area C in the figure to the shaded area D, the stop block 403 is separated from the second force-bearing rod 503.

[0042] A method for using a fresh platycodon grandiflorum cleaning and fresh-keeping packaging device comprises the following steps:

[0043] S1: Fresh Platycodon grandiflorum is first cleaned and dried by a cleaning and drying device; the dried Platycodon grandiflorum is then transported to a bagging device through a conveyor line for vacuum bagging and sealing; the bagged Platycodon grandiflorum is transported to a boxing device through a conveyor line for quantitative boxing; and the collection box 2 filled with Platycodon grandiflorum is transported to a conveying rack 1 of a box closing and packaging device.

[0044] S2: The collection box 2 is moved to the inner side of the support frame 3 by the conveying roller on the conveying frame 1. At this time, the rotating ring 402 will rotate under the driving action of the driving motor 401, and the rotating rotating ring 402 will synchronously drive the stop block 403 to rotate. The stop block 403 first contacts the outer wall of the first force-bearing rod 404, giving the first force-bearing rod 404 an upward thrust, so that the first force-bearing rod 404 moves upward along the inner wall of the support frame 3. The upward moving first force-bearing rod 404 will contact the outward-expanding cover of the collection box 2, giving the cover on the collection box 2 an upward thrust. When the distance of the first force-bearing rod 404 exceeds the rotation axis of the cover, the cover on the collection box 2 will remain in a vertical state.

[0045] S3: After the operation of S2, the collection box 2 continues to move on the conveying roller of the conveying frame 1, and the vertical cover on the moving collection box 2 will approach the rotating rod 409, and the rack 405 will continue to move upward under the action of the first force-bearing rod 404. At this time, the rack 405 will give a rotational thrust to the spur gear 406, and the rotating spur gear 406 drives the first bevel gear 407 to rotate synchronously, so that the first bevel gear 407 engages and drives the second bevel gear 408 and the rotating rod 409 arranged above it to rotate synchronously. Since the position of the rotating rod 409 is above the collection box 2, that is, the rotation position of the cover on the collection box 2, the rotating rotating rod 409 will give a rotational thrust to the cover on the collection box 2, so that the cover closes the collection box 2. At this time, the collection box 2 continues to move forward under the action of the conveying frame 1.

[0046] S4: The initial state of the sealing roll is that the sealing tape at one end extends downward and droops freely, and its drooping edge is lower than the height of the collecting box 2 after capping; when the collecting box 2 is about to move to the bottom of the sealing roller 501, the front end of the collecting box 2 blocks the detection signal of the first infrared detector 10, and the first air valve controls the air pipe to connect with the high-pressure air source, and at the same time allows the high-pressure airflow to be ejected outward through the first hollow cavity 8 and the first high-pressure jet hole 6, which can blow the drooping end of the sealing tape of the sealing roll and fit it to the outer side wall of the front end box body of the collecting box 2; as the collecting box 2 continues to move on the conveying rack 1, the sealing tape is pulled along the upper cover closure docking line for pasting, and during this process the collecting box 2 sequentially blocks the detection signal of the second infrared detector 11.

[0047] S5: When the collecting box 2 moves to the end where it no longer blocks the detection signal of the second infrared detector 11, the rotating ring 402 moves to the highest point and rotates downward to contact the outer wall of the second force-bearing rod 503, thereby giving the second force-bearing rod 503 a thrust to move downward, so that the second force-bearing rod 503 moves downward along the outer wall of the second positioning rod 504 and gives the second spring 505 an extrusion force, and the moving second force-bearing rod 503 simultaneously drives the cutter 502 to move and contact the sealing tape at the end of the collecting box 2 to cut the sealing tape; after the cutting is completed, the second air valve controls the air pipe to be connected to the high-pressure air source, and at the same time allows the high-pressure airflow to be ejected outward through the second hollow cavity 9 and the second high-pressure jet hole 7, which can blow the protruding end of the sealing tape that has been cut off from the sealing roll and adhered to the collecting box 2 and fit it to the outer wall of the terminal box body of the collecting box 2, thereby completing the automatic packaging operation.

[0048] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

8. The method for using the fresh Platycodon grandiflorum cleaning and fresh-keeping packaging device according to claim 4, characterized in that: The steps include: S1: fresh platycodon grandiflorum is firstly cleaned and dried by a cleaning and drying device; the dried platycodon grandiflorum is then conveyed to a bagging device via a conveyor line for vacuum bagging and sealing; the bagged platycodon grandiflorum is conveyed to a boxing device via a conveyor line for quantitative boxing; and the collection box (2) filled with platycodon grandiflorum is conveyed to a conveying frame (1) of a box closing and packaging device; S2: The collection box (2) is moved to the inner side of the support frame (3) by the conveying roller on the conveying frame (1). At this time, the rotating ring (402) will rotate under the driving action of the driving motor (401). The rotating rotating ring (402) will synchronously drive the stop block (403) to rotate. The stop block (403) first contacts the outer wall of the first force-bearing rod (404), giving the first force-bearing rod (404) an upward thrust, so that the first force-bearing rod (404) moves upward along the inner wall of the support frame (3). The upwardly moving first force-bearing rod (404) contacts the outwardly extended cover of the collection box (2), giving the cover on the collection box (2) an upward thrust. When the distance of the first force-bearing rod (404) exceeds the rotation axis of the cover, the cover on the collection box (2) will remain in a vertical state; S3: After the operation of S2, the collection box (2) continues to move on the conveying roller of the conveying frame (1), and the vertical cover on the moving collection box (2) will approach the rotating rod (409), and the rack (405) will continue to move upward under the action of the first force-bearing rod (404). At this time, the rack (405) will give the spur gear (406) a rotational thrust, and the rotating spur gear (406) drives the first bevel gear (407) to rotate synchronously, so that the first bevel gear (407) engages and drives the second bevel gear (408) and the rotating rod (409) arranged above it to rotate synchronously. Since the position of the rotating rod (409) is located at the rotation point of the cover of the collection box (2), the rotating rotating rod (409) will give the cover of the collection box (2) a rotational thrust, so that the cover closes the collection box (2). At this time, the collection box (2) continues to move forward under the action of the conveying frame (1); S4: The initial state of the sealing roll is that the sealing tape at one end extends downward and droops freely, and its drooping edge is lower than the height of the collecting box (2) after the cover is sealed; when the collecting box (2) is about to move to the bottom of the sealing roller (501), the front end of the collecting box (2) blocks the detection signal of the first infrared detector (10), the first air valve controls the air pipe to connect with the high-pressure air source, and at the same time allows the high-pressure air flow to be ejected outward through the first hollow cavity (8) and the first high-pressure jet hole (6), so as to blow the drooping end of the sealing tape of the sealing roll and make it fit the outer wall of the front box body of the collecting box (2); as the collecting box (2) continues to move on the conveying frame (1), the sealing tape is pulled along the upper cover closure connection line for pasting, and during this process, the collecting box (2) sequentially blocks the detection signal of the second infrared detector (11); S5: When the collection box (2) moves to the end where it no longer blocks the detection signal of the second infrared detector (11), the rotating ring (402) moves to the highest point and rotates downward to contact the outer wall of the second force-bearing rod (503), thereby giving the second force-bearing rod (503) a thrust to move downward, so that the second force-bearing rod (503) moves downward along the outer wall of the second positioning rod (504) and gives the second spring (505) a squeezing force. The moving second force-bearing rod (503) synchronously drives the cutter (502) to move and contact the sealing tape at the end of the collection box (2) to cut the sealing tape. After the cutting is completed, the second air valve controls the air pipe to be connected to the high-pressure air source, and at the same time allows the high-pressure airflow to be ejected outward through the second hollow cavity (9) and the second high-pressure jet hole (7), so that the protruding end of the sealing tape that has been cut off from the sealing roll and adhered to the collection box (2) can be blown and attached to the outer wall of the end box body of the collection box (2), thereby completing the automatic packaging operation.
