A cutting station and a removal station are sequentially arranged along the conveying direction of the box conveyor. The cutter assembly is located at the cutting station and can cut the cable ties at the bottom of the packaging box when the box conveyor conveys the packaging box to the removal station. The suction cup assembly is located at the removal station and can pick up the outer hinge of the packaging box after the cable tie is cut. The cable tie removal assembly is located at the removal station and can remove the cut cable tie after the outer hinge of the packaging box is picked up.

[0005] As a further improvement to the above technical solution: The automatic packaging box cable tie removal device also includes a box lifting component, which is located at the removal station and can lift the packaging box upwards to detach it from the box conveyor.

[0006] The cable tie removal assembly includes a lifting drive, a mounting plate, a translation drive, and an L-shaped hook. The lifting drive is mounted above the box conveyor, the mounting plate is mounted on the drive end of the lifting drive, and the translation drive and the L-shaped hook are both mounted on the mounting plate. The L-shaped hook can reciprocate under the drive of the translation drive, and the driving direction of the translation drive is parallel to the conveying direction of the box conveyor.

[0007] The translation drive and the L-shaped hook are both provided in pairs. Each translation drive drives one L-shaped hook. The lower end of one L-shaped hook is provided with a groove that can cooperate with the other L-shaped hook to clamp the cable tie.

[0008] The removal station is equipped with a recycling drive and a sliding mounting block. The sliding mounting block is installed on the drive end of the recycling drive and can reciprocate under the drive of the recycling drive. The lifting drive is installed on the sliding mounting block. The driving direction of the recycling drive is perpendicular to the conveying direction of the box conveyor.

[0014] Compared with the prior art, the advantages of the present invention are as follows: (1) The automatic cable tie removal device for packaging boxes of the present invention includes a box conveyor, a cutter assembly, a suction cup assembly, and a cable tie removal assembly. A cutting station and a removal station are sequentially arranged along the conveying direction of the box conveyor. The cutter assembly is located at the cutting station and can cut the cable ties at the bottom of the packaging box when the box conveyor transports the packaging box to the removal station. The suction cup assembly is located at the removal station and can pick up the outer hinge of the packaging box after the cable tie is cut. The cable tie removal assembly is located at the removal station and can remove the cut cable tie after the outer hinge of the packaging box is picked up. The box conveyor is used for... The packaging box is conveyed downstream. As the packaging box moves from the cutting station to the removal station, the cutting component cuts the cable ties on the packaging box. When the packaging box reaches the removal station, the suction cup component picks up the outer hinge of the packaging box, causing the outer hinge to tilt up and creating a gap between the cable tie and the inner hinge of the packaging box. This allows the cable tie removal component to grab the cable tie. After grabbing the cable tie, the cut cable tie can be removed from the packaging box. The whole process is completed automatically without manual operation. The high degree of automation not only reduces the intensity of manual labor but also improves production efficiency.

[0015] (2) The automatic removal method for cable ties of the packaging box of the present invention uses a cutting component to cut the cable ties at the bottom of the packaging box, and a suction cup component to lift the outer hinge of the packaging box, thereby creating a gap between the cable tie and the inner hinge of the packaging box, which facilitates the removal of the cable tie by the cable tie removal component. The cable tie is removed by the cable tie removal component, which is reliable in operation, reduces the intensity of manual labor, and improves production efficiency. Since the cable tie is cut at the bottom of the packaging box, the cutting of the cable tie is achieved by the contact between the packaging box itself and the cutting component, which can achieve continuous cutting. When the packaging box is transported on the box conveyor, its bottom position is fixed, so there is no need to position the packaging box before cutting, which simplifies the operation and improves production efficiency.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Figures 1 to 6 An embodiment of the automatic packaging box cable tie removal device of the present invention is shown. The device includes a box conveyor 1, a cutter assembly 2, a suction cup assembly 3, and a cable tie removal assembly 4. A cutting station and a removal station are sequentially arranged along the conveying direction of the box conveyor 1. The cutter assembly 2 is located at the cutting station and can be used when the box conveyor 1 is conveying the packaging box 8 to the removal station (e.g., ...). Figure 2 (As indicated by the arrow in the image) The cable tie 9 is cut. The suction cup assembly 3 is positioned at the removal station and can pick up the outer hinge of the packaging box 8 after the cable tie 9 is cut. The cable tie removal assembly 4 is positioned at the removal station and can remove the cut cable tie 9 after the outer hinge of the packaging box 8 is picked up. The box conveyor 1 is used to drive the packaging box 8 downstream. During the process of the packaging box 8 moving from the cutting station to the removal station, the cutter assembly 2 cuts the cable tie 9 on the packaging box. When the packaging box 8 reaches the removal station, the suction cup assembly 3 picks up the outer hinge of the packaging box 8, causing the outer hinge to tilt up, thereby creating a gap between the cable tie 9 and the inner hinge and bottle of the packaging box 8, so that... The cable tie removal component 4 picks up the cable tie 9, and after picking up the cable tie 9, the cut cable tie 9 can be removed from the packaging box 8. The whole process is completed automatically without manual operation, which not only reduces the intensity of manual labor, but also improves production efficiency. Since the cable tie 9 is cut at the bottom of the packaging box 8, it is achieved by the contact between the packaging box 8 and the cutting component 2, which can achieve continuous cutting and improve production efficiency. Moreover, since the bottom position of the packaging box 8 is fixed when it is transported on the box body conveyor 1, there is no need to set up an additional positioning mechanism to position the packaging box 8, which simplifies the structure.

[0025] In this embodiment, the bottle packaging box cable tie removal device also includes a box lifting member 5. The box lifting member 5 is set at the removal station and can lift the packaging box 8 upward so that the packaging box 8 is separated from the box conveyor 1. The cable tie removal component 4 is installed above the box lifting member 5. After the cable tie 9 is cut, it is transported to the removal station along with the packaging box 8. At this time, since the packaging box 8 is full of bottle packs and has a large weight, the cable tie 9 is clamped by the bottom of the packaging box 8 and the box conveyor 1. The box lifting member 5 can lift the packaging box 8 upward after it is transported to the removal station so that the packaging box 8 is separated from the box conveyor 1, making it easier for the cable tie removal component 4 to remove the cable tie 9.

[0026] In this embodiment, the cable tie removal assembly 4 includes a lifting drive 41, a mounting plate 42, a translation drive 43, and an L-shaped hook 44. The lifting drive 41 is mounted above the box conveyor 1, and the mounting plate 42 is mounted on the drive end of the lifting drive 41. The translation drive 43 and the L-shaped hook 44 are both mounted on the mounting plate 42. The L-shaped hook 44 can reciprocate under the drive of the translation drive 43. The driving direction of the translation drive 43 is parallel to the conveying direction of the box conveyor 1. When the box lifting component 5 lifts the packaging box 8 upwards and separates it from the box conveyor 1, since there is no gap between the top hinge of the packaging box 8 and the bottle pack inside, the suction cup assembly 3 is used to hold the packaging box 8 in place. The outer hinge is tilted up, creating a gap between the cable tie 9 and the inner hinge of the packaging box 8. The lifting drive 41 drives the L-shaped hook 44 to descend until the lower hook of the L-shaped hook 44 is below the cable tie 9 above the top hinge. Then, the translation drive 43 drives the L-shaped hook 44 to translate until the lower hook is directly below the cable tie 9 above the outer hinge. The lifting drive 41 drives the L-shaped hook 44 to rise, and the lower hook of the L-shaped hook 44 hooks the cable tie 9 and removes the cable tie 9 from the packaging box 8. The cable tie removal component 4 in this embodiment can be applied to packaging boxes of different sizes, and only the rising and falling of the lifting drive 41 and the moving distance of the translation drive 43 need to be adjusted.

[0027] In this embodiment, two translation drive members 43 and two L-shaped hooks 44 are provided. Each translation drive member 43 drives one L-shaped hook 44. The lower end of one L-shaped hook 44 is provided with a groove that can cooperate with the other L-shaped hook 44 to clamp the cable tie 9. The two L-shaped hooks 44 translate relative to each other and cooperate to clamp the cable tie 9, preventing the cable tie 9 from falling when the lifting drive member 41 drives the L-shaped hooks 44 to move upward, thus increasing the reliability of operation.

[0028] In this embodiment, the removal station is provided with a recycling drive 71 and a sliding mounting block 72. The sliding mounting block 72 is installed on the drive end of the recycling drive 71 and can reciprocate under the drive of the recycling drive 71. The lifting drive 41 is installed on the sliding mounting block 72. The driving direction of the recycling drive 71 is perpendicular to the conveying direction of the box conveyor 1. When the cable tie 9 is removed from the packaging box 8 by the cable tie removal component 4, the recycling drive 6 drives the sliding mounting block 7 and the cable tie removal component 4 to move so as to move the cable tie 9 to the recycling position.

[0029] In this embodiment, the suction cup assembly 3 includes a mounting arm 31, a vertical drive component 32, and a vacuum suction cup 33. The mounting arm 31 is mounted above the box conveyor 1, the vertical drive component 32 is mounted on the mounting arm 31, and the vacuum suction cup 33 is mounted on the drive end of the vertical drive component 32. When the packaging box 8 reaches the removal station, the vertical drive component 32 drives the vacuum suction cup 33 to descend to the outer hinge. The vacuum suction cup 33 sucks on the outer hinge, causing the outer hinge to lift up, thereby creating a gap between the cable tie 9 and the inner hinge of the packaging box 8, so that the L-shaped hook 44 can hook the cable tie 9.

[0030] In this embodiment, the box conveyor 1 includes two conveyor belts 11 with a gap between them, the cutter assembly 2 is disposed between the two conveyor belts 11, and the box lifting component 5 is disposed between the two conveyor belts 11.

[0031] In this embodiment, the cutter assembly 2 includes a cutter 21, a rotary drive 22, a connecting plate 23, and a reset member 24. The connecting plate 23 is connected to the rotary drive 22 and can rotate under the drive of the rotary drive 22. The cutter 21 is rotatably mounted on the connecting plate 23. The reset member 24 is disposed between the connecting plate 23 and the cutter 21 so that the tip of the cutter 21 is higher than the conveying surface of the conveyor belt 11 before being pressed by the packaging box 8. The rotary drive 22 can drive the cutter 21 to rotate. After the previous packaging box 8 is conveyed to the removal station, the cutter 21 returns to its original position under the action of the reset member 24, so that the tip of the cutter 21 is higher than the conveying surface of the conveyor belt 11 before being pressed by the next packaging box 8, so as to ensure that the cable tie 9 can be cut.

[0032] In this embodiment, the bottle packaging box tie removal device also includes a liftable positioning block 6. The positioning block 6 is located downstream of the removal station and prevents the packaging box 8 on the removal station from moving downstream when it is raised.

[0033] In this embodiment, the bottle packaging box cable tie removal device also includes a cable tie recycling box 10. The cable tie recycling box 10 is located on one side of the removal station and below the L-shaped hook 44 to receive the cable ties 9 removed by the cable tie removal component 4. When the recycling drive 6 moves the L-shaped hook 44 to directly above the cable tie recycling box 5, the translation drive 43 moves the L-shaped hook 44 to release the cable tie 9, and the cable tie 9 falls into the cable tie recycling box 5.

[0034] The automatic removal method for packaging box cable ties of the present invention includes the following steps: S1. Start the box conveyor 1 to convey the packaging box 8; S2. During the process of conveying the packaging box 8 from the cutting station to the removal station, the cutting assembly 2 cuts the cable ties 9 at the bottom of the packaging box 8. S3. When the packaging box 8 arrives at the removal station, the suction cup assembly 3 is activated to pick up the outer hinge of the packaging box 8, causing the outer hinge to lift up and thus creating a gap between the cable tie 9 and the inner hinge of the packaging box. S4. Activate the cable tie removal component 4 to remove the cut cable ties 9.

[0035] The automatic removal method for cable ties in this embodiment first uses the cutter assembly 2 to cut the cable ties 9 at the bottom of the packaging box 8. After the packaging box 8 reaches the removal station, the suction cup assembly 3 is activated to lift the outer hinge of the packaging box 8, causing the outer hinge to tilt up and creating a gap between the cable tie 9 and the inner hinge of the packaging box. This allows the cable tie removal assembly 4 to grab the cable tie 9. Subsequently, the cable tie removal assembly 4 is activated to remove the cut cable tie 9, thus achieving automatic removal of the cable tie 9. The method is reliable, requires no manual operation, reduces labor intensity, and improves production efficiency. Since the cable tie 9 is cut at the bottom of the packaging box 8, the cutting of the cable tie 9 is achieved by the contact between the packaging box 8 and the cutter assembly 2, allowing for continuous cutting. When the packaging box 8 is transported on the box conveyor 1, its bottom position is fixed, so there is no need to position the packaging box 8 before cutting, simplifying the operation and improving production efficiency.

[0036] In this embodiment, the cable tie removal component 3 includes an L-shaped hook 44 that can be raised, lowered, and translated. In step S4, the L-shaped hook 34 is moved until the lower hook body enters the gap between the cable tie 9 and the inner hinge. Then, the L-shaped hook 34 is raised, and the lower hook body hooks up the cable tie 9 and removes the cable tie 9 from the packaging box 8.

[0037] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention.
