Description

Technical Field

[0001] The present invention relates to the field of string threading machines, and particularly to a carton string threading machine. Background Art

[0002] The existing string threading machines are generally applied to the string threading of paper bags. For example, a string threading machine for handbags disclosed in the patent with publication number CN222039835U on November 22, 2024, directly transports the handbags in the feeding mechanism into the punching mechanism and the string threading mechanism after clamping them by the conveying mechanism. Since the opening of the paper bag is small and the opening of the paper box is large, the paper box needs to be opened before punching and string threading. Therefore, if such a string threading machine is to be applied to paper boxes, there will be limitations. Therefore, there is an urgent need for a string threading machine for paper boxes.

[0020] The following further describes the embodiments of the present invention with reference to the drawings: As shown in the figure, a carton stringing machine includes a feeding mechanism 4, a transporting mechanism 5, a hole-opening mechanism 6, a stringing mechanism 7, a patch-attaching mechanism 8 and a discharging mechanism 9. An unpacking mechanism 1 for unpacking cartons is provided between the feeding mechanism 4 and the transporting mechanism 5. The unpacking mechanism 1 includes a suction cup seat 11, a first power component for driving the suction cup seat 11 to move back and forth, a material-blocking component located at at least one side of the suction cup seat 11, and a second power component for driving the material-blocking component to move back and forth. The movement trajectories of the material-blocking component and the suction cup seat 11 are parallel to each other. In the unpacking mechanism of the cartons in this technical solution, the cartons are sucked from the feeding mechanism and unpacked. The unpacked cartons are successively subjected to processes such as hole-opening, stringing, and patch-attaching by the transporting mechanism, and finally discharged. When performing the unpacking operation, the first power component drives the suction cup seat to move back and forth. The suction cup seat can adsorb the folded cartons and retract backward. During the backward movement, the second power component drives the material-blocking component to move forward. After contacting both ends of the carton, it continues to move forward to achieve the unpacking action of the carton, which has the advantages of good working stability and good practicability.

[0021] Among them, the transporting mechanism, the hole-opening mechanism, the stringing mechanism, the patch-attaching mechanism and the discharging mechanism are all similar in structure to a handbag stringing machine disclosed in the patent with the publication number CN222039835U, and the working principles are also similar, so no further elaboration will be made here.

[0022] Among them, the original state of the carton is folded into a flat shape. The material-blocking component can be arranged on one side of the suction cup seat or on both sides of the suction cup seat, and both can achieve the unpacking action of the carton. Among them, arranging it on one side of the suction cup seat can already fully achieve the unpacking action of the carton. The reason for arranging it on both sides of the suction cup seat is that the directions of the cartons are not unified. Sometimes the short side is on the right, and sometimes the short side is on the left. Therefore, arranging the material-blocking components on both sides can ensure the unpacking stability of the cartons. There are three embodiments of the material-blocking component in this technical solution; Embodiment 1: As Figure 1 shown, the side of the material-blocking block 211 close to the suction cup seat 11 is a slope surface, and the slope surface of the material-blocking block can play a guiding role for both sides of the carton.

[0023] Embodiment 2: As Figure 5 shown, the material-blocking component includes a first material-blocking seat 212, a first baffle 213 hingedly installed on the first material-blocking seat 212, and a fourth driving component 214 installed on the first material-blocking seat 212 and driving the first baffle 213 to swing. The fourth driving component uses a cylinder, an oil cylinder or a linear motor, and the output end of the fourth driving component is hinged to the first baffle, and can drive the first baffle to perform a swinging action on the first material-blocking seat. The first baffle and the first material-blocking seat are connected by a pin shaft, and the hole position on the first baffle will be appropriately enlarged in size to prevent the first baffle from jamming during swinging.

[0024] Example 3: As Figure 4 shown, the material blocking component includes a second material blocking seat 215, a second baffle 216 slidably mounted on the second material blocking seat 215, and a fifth driving member 217 mounted on the second material blocking seat 215 and driving the second baffle 216 to slide. The fifth driving member uses a cylinder, an oil cylinder or a linear motor, which controls the second baffle to move towards the suction cup seat direction to complete the unpacking work of the carton.

[0025] Example 4: The material blocking component includes a third material blocking seat 218 and a suction nozzle 219 mounted on the inner side wall of the third material blocking seat. The carton is first touched by the third material blocking seat, and then the side of the carton is tilted and contacts the suction nozzle and is adsorbed until the unpacking work of the carton is completed.

[0026] It further includes a bracket 3 for installing the first power component and the second power component.

[0027] The first power component includes: A first driving member 12, which is fixedly mounted on the bracket 3 and has a first gear 13 at its output end; A first rack 14, which is slidably mounted on the bracket 3 and meshes with the first gear 13; The end of the first rack 14 is fixedly connected to the suction cup seat 11. The first driving member uses a servo motor, which drives the first rack to move back and forth through the forward and reverse rotation of the first gear.

[0028] In addition, another embodiment of the first power component is to use a cylinder, an oil cylinder or a linear motor, and its output end is fixedly connected to the suction cup seat.

[0029] The suction cup seat 11 is provided with a plurality of first guide shafts 15 slidably engaged with the bracket 3 at the four corners, which ensures the smoothness of the forward and backward movement of the suction cup seat. The front surface of the suction cup seat 11 is provided with a plurality of suction nozzles 16, and the suction nozzles are connected to a negative pressure device through hoses to firmly adsorb the side wall surface of the carton.

[0030] The second power component includes: A connecting frame 22, and there are connecting rods 23 fixedly connecting the two ends thereof to the material blocking component; A second driving member 24, which is fixedly mounted on the bracket 3 and has a second gear 25 at its output end; A moving seat 26, which is slidably mounted on the bracket 3 and is connected to the connecting frame 22; The second rack 27 is fixedly installed on the moving seat 26 and meshes with the second gear 25. The second driving member is a servo motor, which drives the second rack and the moving seat to move forward and backward through the forward and reverse rotation of the second gear. The moving seat drives the connecting rods and the blanking blocks on both sides to move forward and backward synchronously through the connecting frame.

[0031] It further includes an adjusting member for adjusting the lateral position of the blanking member. The adjusting member includes: Two adjusting frames 28 are symmetrically arranged on both sides of the suction cup seat 11 and are slidably matched with the connecting rod 23; A screw rod 29 is provided with a positive thread portion 291 and a reverse thread portion 292 that are threadedly matched with the adjusting frame 28 at both ends; A third driving member 20 has its output end linked to the end of the screw rod 29. The third driving member adopts a servo motor and a pulley structure, which drives the screw rod to rotate. The positive thread portion and the reverse thread portion on the screw rod can make the two adjusting frames move synchronously towards and away from each other.

[0032] A plurality of second guide shafts 31 that are slidably matched with the adjusting frame 28 are provided on the bracket 3, ensuring the smooth operation of the adjusting frame.

[0033] In addition, another embodiment of the second power member is to adopt a cylinder, an oil cylinder or a linear motor, whose output end is fixedly connected to the blanking block, and the synchronism of the two is controlled by the PLC control system.

[0034] The feeding mechanism 4 is arranged opposite to the box opening mechanism 1. The feeding mechanism 4 includes: A placing platform 41 is provided with a conveyor belt assembly 40 for driving the paper box forward; A first base 42 is fixedly connected below the placing platform 41; A second base 43 is provided with an adjusting screw rod 44 rotatably installed and is located below the first base 42; A nut sleeve 45 that is threadedly matched with the adjusting screw rod 44 is provided on the first base 42. A plurality of third guide shafts 46 that are slidably matched with the first base 42 are provided on the second base 43. When the adjusting screw rod on the second base rotates, it can drive the first base to move up and down, thereby adjusting the height position of the placing platform to adapt to paper boxes of different sizes.

[0035] The feeding mechanism 4 further includes: A sliding track 47 is installed above the placing platform 41; A sliding seat 48 is slidably installed on the sliding track 47 and is always subjected to a forward traction force; A pressing plate 49 is installed below the sliding seat; The pressing plate 49 remains in a vertical state and its side wall is in close contact with the paper box. A power element (not shown) is provided in front of the sliding seat and drives the sliding seat to perform linear sliding on the sliding track through a traction rope (not shown). This traction force always keeps the pressing plate in close contact with the paper box.
