[0037] The techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered part of the specification where appropriate.

[0038] As Figures 1-14 The strip box unpacking and replenishing device provided by the embodiment includes: a high-altitude buffer conveying mechanism 1 arranged above a strip box packaging machine and used for buffering a strip box trademark paper 9; a vertical displacement mechanism 2 movably arranged at one end of the high-altitude buffer conveying mechanism 1 in a vertical direction; a horizontal displacement mechanism 3 movably arranged at the bottom right of the vertical displacement mechanism 2 in a horizontal direction; a lifting unpacking mechanism 4 arranged above the horizontal displacement mechanism 3 and used for unpacking kraft paper on the strip box trademark paper 9; a lifting kraft paper recycling mechanism 5 arranged below the horizontal displacement mechanism 3 and used for recycling the unpacked kraft paper; a receiving platform 7 also arranged below the horizontal displacement mechanism 3; and a descending mechanism 6 arranged at the right of the horizontal displacement mechanism 3 and used for rotating and feeding the unpacked strip box trademark paper 9 onto a feeding port 8 of the strip box packaging machine.

[0039] The high-altitude buffer conveying mechanism 1 is installed on a bracket, and specifically includes a plurality of conveying belts arranged in sequence in a horizontal direction. Figure 1 And Figure 2As shown, in this invention, there are two conveyor belts. It should be noted that this invention does not specifically limit the number and length of the conveyor belts. After the RGV trolley transports the carton label paper 9 to its position, it is handed over to the conveyor belt. The carton label paper 9 can be transported and buffered on the conveyor belt. In specific implementation, each conveyor belt is selected according to the general external dimensions of the carton label paper 9 to meet the needs of various specifications and shapes of carton label paper 9. The buffer amount and conveying of the label paper can be controlled by the operation of the belt conveyor. The number of conveying components can be freely increased or decreased according to the relative distance between the carton packaging machine and the RGV conveyor line. In this invention, the conveyor belt adopts a modular design, which is convenient to install. When the downstream carton packaging machine issues a material request, the conveyor belt transports the carton label paper 9 to the vertical shifting mechanism 2 and hands it over to the vertical shifting mechanism 2.

[0040] During operation, the carton label paper 9 is transported by the RGV trolley to the high-altitude buffer conveyor 1 for buffering. When the carton label paper 9 of the packaging machine below is consumed to a certain extent, the carton label paper 9 buffered at the top will enter the vertical shift mechanism 2. The lifting component of the vertical shift mechanism 2 will transport the carton label paper 9 to the lower layer. The horizontal shift mechanism 3 moves onto the lifting component, clamps the carton label paper 9 and transports it to the receiving platform 7. Then, the unsealing mechanism 4 and the kraft paper recycling mechanism 5 move. The unsealing mechanism 4 unseales the kraft paper on the carton label paper 9. Then, the kraft paper recycling mechanism 5 descends and rolls the unsealed kraft paper into the recycling box 56. The receiving platform 7 receives the unsealed carton label paper 9 that is transported with the horizontal shift mechanism 3 and docks with the descending mechanism 6. Finally, the horizontal shift mechanism 3 hands the carton label paper 9 to the descending mechanism 6, which rotates the carton label paper 9 and discharges it onto the feeding port 8 of the carton packaging machine.

[0041] Furthermore, such as Figure 13 As shown, the receiving platform 7 further includes a first receiving platform 71, a movable receiving platform 72, and a fixed receiving platform 73 arranged sequentially. The first receiving platform 71 is installed behind the vertical shifting mechanism 2; the unsealing mechanism 4 is installed above the first receiving platform 71; and the kraft paper recycling mechanism 5 is installed behind the first receiving platform 71.

[0042] Furthermore, such as Figure 4As shown, the vertical shifting mechanism 2 includes: a linear module 21 arranged vertically; a first slider 22 that can slide vertically along the linear module 21 is provided on the right side of the linear module 21; a lifting back plate 23 is provided on the right side of the first slider 22; a lifting baffle 24 is provided on the right side of the lifting back plate 23; and a lifting support plate 26 arranged horizontally is provided on the right side of the lifting baffle 24. The upper surface of the lifting support plate 26 can be moved to be flush with the upper surface of the high-altitude buffer conveying mechanism 1. Several pulleys 27 are provided on the lifting support plate 26 to facilitate the sliding of the carton label paper 9 onto the lifting baffle 24. The linear module 21 is mounted on a corresponding support assembly.

[0043] Furthermore, the lifting back plate 23 is mounted on the first slider 22 by screws, and the lifting baffle 24 is connected to the lifting back plate 23 by studs 28; a lifting bracket 25 is provided below the lifting support plate 26 to support the lifting support plate 26, and the lifting bracket 25 is fastened to the lifting baffle 24 to support the lifting support plate 26; and the lifting support plate 26 is connected to the lifting baffle 24. In this invention, the lifting assembly consists of the lifting back plate 23, the lifting baffle 24, the lifting bracket 25, the lifting support plate 26, the pulley 27, and the studs 28. The entire lifting assembly can move up and down along the linear module 21 with the first slider 22. When the carton label paper 9 is conveyed to the end of the high-altitude buffer conveying mechanism 1, the lifting assembly rises, causing the upper plane of the lifting plate 26 to move to be flush with the upper surface of the high-altitude buffer conveying mechanism 1. The carton label paper 9 is slid into the lifting plate 26 by the movement of the conveyor belt. When the carton label paper 9 slides on the pulley 27 and gets close to the lifting baffle 24, the conveyor belt stops moving, and the carton label paper 9 moves vertically downward with the entire lifting assembly.

[0044] Furthermore, such as Figure 5 As shown, the horizontal shifting mechanism 3 includes two first linear guide rails 31 arranged parallel to each other in the horizontal direction. A first mounting plate 32 is disposed between the two first linear guide rails 31. Below the first mounting plate 32, second sliders 33 are respectively disposed on the two first linear guide rails 31. Above the first mounting plate 32, two second linear guide rails 34 are arranged side-by-side in the vertical direction. Each second linear guide rail 34 is respectively provided with a third slider 37 that can move along the direction of the second linear guide rail 34 (i.e., the vertical direction). A left material clamping plate 38 and a right material clamping plate 35 for clamping the label paper 9 of the carton are respectively disposed on the front and rear sides below each third slider 37. The two first linear guide rails 31 are mounted on the base plate by a support assembly, allowing the entire horizontal shifting mechanism 3 to move along the direction of the first linear guide rails 31 (i.e., the horizontal direction) under the drive of the second sliders 33. The second linear guide rails 34 are fixedly connected to the first mounting plate 32.

[0045] Furthermore, the first mounting plate 32 is connected to the corresponding second sliders 33 by screws; the left material clamping plate 38 and the right material clamping plate 35 are connected to the third slider 37 by screws and can move with the movement of the third slider 37; a left material clamping top plate 39 is provided on the inner side of the left material clamping plate 38; a right material clamping top plate 36 is provided on the inner side of the right material clamping plate 35. After the carton label paper 9 descends to its position with the vertical shifting mechanism 2, the first mounting plate 32 of the horizontal shifting mechanism 3 moves toward the vertical shifting mechanism 2 with the second sliders 33. After moving to its position, the third slider 37 on the second linear guide rail 34 moves toward the carton label paper 9, causing the left material clamping plate 38, the right material clamping plate 35, the left material clamping top plate 39, and the right material clamping top plate 36 to clamp the carton label paper 9, and as... Figure 6 As shown, in this invention, the left material clamping plate 38, right material clamping plate 35, left material clamping top plate 39, and right material clamping top plate 36 are designed according to the shape of the carton label paper 9, and can clamp the protrusions of the carton label paper 9. They are also modularly designed to accommodate different specifications of carton label paper 9. After the left material clamping plate 38, right material clamping plate 35, left material clamping top plate 39, and right material clamping top plate 36 clamp the carton label paper 9, the material stack can be organized. The carton label paper 9 moves to the first receiving platform 71 along with the horizontal shifting mechanism 3, and the unsealing mechanism 4 operates, unsealing the carton label paper 9 and transporting it to the lowering mechanism 6.

[0046] Furthermore, such as Figure 7 and Figure 8As shown, the unpacking mechanism 4 includes two liftable third linear guide rails 41 fixed on the bracket assembly. A linear guide rail connecting plate 49 is provided on the side wall of the slider of each third linear guide rail 41. A second mounting plate 46 is provided between the lower ends of each linear guide rail connecting plate 49. A fourth linear guide rail 42 is provided on the second mounting plate 46. A knife holder 45 is mounted on the slider of the fourth linear guide rail 42, and can move with the movement of the slider. A cutter 47 is mounted on the knife holder 45. A first suction cup frame 43 and a linear cylinder push rod 44 are also provided on the second mounting plate 46. The first suction cup frame 43 is connected to the linear cylinder push rod 44, and the linear cylinder push rod 44 can move back and forth with the movement of the linear cylinder push rod 44. A plurality of first vacuum suction cups 48 for adsorbing kraft paper are provided on the first suction cup frame 43. In some embodiments of the present invention, the first suction cup frame 43 and the linear cylinder push rod 44 are respectively connected to the corresponding bracket, side plate, and second mounting plate 46 by bolts, and move up and down with the third linear guide rail 41. In a specific implementation, after the carton label paper 9 is conveyed to the first receiving platform 71 by the horizontal shifting mechanism 3, the unsealing mechanism 4 moves vertically downward under the drive of the third linear guide rail 41. The first vacuum suction cup 48 descends with the descent of the second mounting plate 46 until the first vacuum suction cup 48 presses and sucks up the kraft paper on the upper side of the carton label paper 9; at the same time, the linear cylinder push rod 44 mounted on the side plate pushes the first suction cup frame 43 toward the carton label paper 9 so that the first vacuum suction cup 48 on the first suction cup frame 43 sucks up the kraft paper on the side. Then the linear cylinder push rod 44 retracts in the direction away from the carton label paper 9, pulling the kraft paper out of the gap. At this point, the knife holder 45 and the cutter 47 move from the initial position to the final position along with the slider of the fourth linear guide 42, cutting the kraft paper, and then return to the initial position. The first vacuum suction cup 48 stops working, and the unsealing mechanism 4 moves vertically upward under the drive of the third linear guide 41, completing one workflow. It should be noted that in this invention, the initial position and the highest position of the slider of the fourth linear guide 42 are adjustable.

[0047] Furthermore, such as Figure 9 and Figure 10As shown, the kraft paper recycling mechanism 5 includes a mounting back plate 52. A first roller 51 is provided on the side wall of the mounting back plate 52. A second linear cylinder 53 connected to the first roller 51 is also provided on the side wall of the mounting back plate 52, and the second linear cylinder 53 is located outside the first roller 51. A second suction cup frame is provided on one side of the first roller 51. A plurality of second vacuum suction cups 54 are provided on the second suction cup frame for adsorbing the lower side of the kraft paper. A recycling box 56 is provided below the second suction cup frame. An arc-shaped guide plate 55 is provided between the second suction cup frame and the recycling box 56. A second roller 57 is provided above the recycling box 56. A third linear cylinder 59 is provided below the first roller 51. Guide rods 58 are provided on both sides of the third linear cylinder 59. In one embodiment of the present invention, the first roller 51 is mounted on the mounting side plate, and the second linear cylinder 53 is mounted on the outer side of the mounting side plate to drive the first roller 51 to move back and forth; the recycling box 56 is mounted on the lower side of the mounting base plate to receive the unpacked kraft paper; the second roller 57 is mounted on the upper side of the mounting base plate; and the third linear cylinder 59 is mounted on the lower side of the mounting base plate. Since the guide rod 58 is connected to the base plate of the entire kraft paper recycling mechanism 5, the entire kraft paper recycling mechanism 5 can move up and down. In a specific implementation, when the horizontal shifting mechanism 3 moves in the direction of the vertical shifting mechanism 2, the third linear cylinder 59 starts to work, pushing the kraft paper recycling mechanism 5 upward, so that the mounting base plate is flush with the first receiving platform 71. After the horizontal shifting mechanism 3 conveys the carton label paper 9 to the first receiving platform 71, the unsealing mechanism 4 starts working. Simultaneously, the second linear cylinder 53 operates, pushing the second suction cup frame towards the carton label paper 9, causing the second vacuum suction cup 54 to adhere to the lower half of the carton label paper 9. After the suction is tight, the second linear cylinder 53 retracts, assisting the unsealing mechanism 4 in pulling the kraft paper out of the gap. When the unsealing mechanism 4 completes its work, the third linear cylinder 59 returns to its stop position, and the second linear cylinder 53 pushes again towards the carton label paper 9, activating the first roller 51 and the second roller 57. The second vacuum suction cup 54 stops working. Simultaneously, the movable receiving platform 72 moves towards the first receiving platform 71. After reaching its position, the unsealed carton label paper 9 is transported to the fixed receiving platform 73 along with the horizontal shifting mechanism 3. At this time, the first roller 51 and the second roller 57 roll the kraft paper along the guide plate 55 into the recycling bin 56, completing the process.

[0048] Further, the lowering mechanism 6 includes two parallel lifting and moving components 61, wherein the lifting and moving components 61 are mounted on the column, and each lifting and moving component 61 includes a vertical lifting guide rail 611 and a fourth slider 612 that can slide along the vertical lifting guide rail 611; a rotating device 66 is arranged horizontally between the two lifting and moving components 61 to drive the entire receiving device 65 to rotate by a preset angle; a fifth linear guide rail 67 is arranged on the rotating device 66; a receiving device 65 is arranged below the fifth linear guide rail 67. In this invention, the fifth linear guide rail 67 is installed between the lower side of the crossbeam of the rotating device 66 and the receiving device 65, wherein the fifth linear guide rail 67 is mounted between the crossbeam of the rotating device 66 and the receiving device 65. The base plate of the linear guide 67 is connected to the crossbeam of the rotating device 66, and the slider of the fifth linear guide 67 is fixedly connected to the lower receiving device 65. The receiving device 65 has a left gripper 62 and a right gripper 64 on each side. In practice, both the left gripper 62 and the right gripper 64 are bolted to the connecting plate of the receiving device 65.
