[0001] This utility model relates to the field of feeder technology, specifically a feeder for a cartoning machine. Background Technology

[0002] The carton feeder is an important component of an automatic cartoning machine. It is responsible for accurately and efficiently transferring products from the upstream production line into packaging boxes, ensuring the continuity and accuracy of the entire cartoning process.

[0003] In existing cartoning machines, the spacing between the baffles on the conveyor belt is mostly fixed. This requires manual replacement of the guide plates or adjustment of the limiting mechanism to adapt to products of different sizes. This adjustment is time-consuming and prone to positioning deviations.

[0004] To address this issue, a feeding device for a cartoning machine is proposed, which solves the aforementioned problems. Utility Model Content

[0023] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture.

[0024] Please see Figures 1 to 7 This utility model provides a feeding device for a cartoning machine, and the technical solution is as follows:

[0025] A cartoning machine unloader includes a conveyor belt 1, with a main base 2 fixedly mounted in an array on the conveyor belt 1. The main base 2 includes a left base 21 and a right base 22. The left base 21 is slidably connected to a left sliding assembly 3, and the right base 22 is slidably connected to a right sliding assembly 4 above it. The right sliding assembly 4 is engaged with a rotating assembly 5 below it, and the rotating assembly 5 is engaged with the left sliding assembly 3. The conveyor belt 1 is used to transport packaging boxes, and the main base 2 is used to limit the position of the falling packaging boxes, facilitating the accurate grasping or pushing of products into the boxes by actuators such as robotic arms and push rods. The cooperation between the left base 21 and the left sliding assembly 3 allows the left baffle 31 in the left sliding assembly 3 to move to the left, increasing the distance between the baffles. The cooperation between the right base 22 and the right sliding assembly 4 allows the right baffle 41 in the right sliding assembly 4 to move to the right. When the conveyor belt 1 transmits the right sliding assembly 4 and the left sliding assembly 3 to the rotating assembly 5, the rotating assembly 5 sequentially provides power to the right sliding assembly 4 and the left sliding assembly 3, causing the right baffle 41 to move to the right and the left baffle 31 to move to the left. The left sliding assembly 3 includes a left baffle 31 slidably connected to the left base 21, and protrusions are installed at both ends of the bottom of the left baffle 31. A first row of teeth 32 is fixedly connected to the lower end of the left baffle 31 near the rotating assembly 5. A first gear 33 is engaged below the first row of teeth 32, and the first gear 33 is rotatably connected to one side of the left base 21. A rack 34 is engaged below the first gear 33, and a protrusion is installed on the inner side of the rack 34. The left base 21 provides sliding space for the protrusions on the left baffle 31, allowing the left baffle 31 to slide on the left base 21. The first row of teeth 32 is used to engage the first gear 33, and the rotation of the gear can drive the movement of the left baffle 31. Since the first gear 33 is rotatably connected to the left base 21, the first gear 33 will not change position with rotation, but will only rotate in place. The rack 34 has teeth on both its upper and lower surfaces. The upper teeth mesh with the first gear 33. When the first gear 33 rotates, it moves the left baffle 31 to the left and moves the rack 34 to the left. The lower teeth mesh with the rotating assembly 5. When the conveyor belt 1 transfers the left sliding assembly 3 to the rotating assembly 5, the rotating assembly 5 rotates clockwise. The rotating assembly 5 drives the rack 34 to move to the right. The rack 34 moving to the right causes the first gear 33 to rotate counterclockwise, thereby driving the left baffle 31 to move to the left, thus increasing the position of the left side.

[0026] like Figure 2 and Figure 4As shown, the right sliding assembly 4 includes a right baffle 41 slidably connected to the right base 22, and protrusions are installed at both ends of the bottom of the right baffle 41. A second row of teeth 42 is fixedly connected to the lower end of the right baffle 41 near the rotating assembly 5, and the second row of teeth 42 meshes with the rotating assembly 5. The right base 22 provides sliding space for the protrusions on the right baffle 41, allowing the right baffle 41 to slide on the left base 21. Since the second row of teeth 42 meshes with the rotating assembly 5, when the conveyor belt 1 conveys the right sliding assembly 4 to the rotating assembly 5, the rotating assembly 5 rotates clockwise, and the rotating assembly 5 drives the right baffle 41 at the top of the second row of teeth 42 to move to the right, thereby increasing the position of the right side.

[0027] like Figure 5 As shown, the rotating assembly 5 includes a drive gear 51 that meshes with the second row of teeth 42. The drive gear 51 is fixedly connected to a telescopic rod 52, which is rotatably connected to one end of a fixed plate 53. The fixed plate 53 is fixedly connected to a motor 54, and the output shaft of the motor 54 is connected to the telescopic rod 52. The other end of the fixed plate 53 is fixedly connected to a support plate 11 of the inner ring of the conveyor belt 1. The fixed plate 53 provides support force to the drive gear 51, and the output shaft of the motor 54 provides power to the rotation of the drive gear 51. The rotational speed of the drive gear 51 is greater than the moving speed of the conveyor belt 1. The motor 54 can control the extension and retraction of the telescopic rod 52. After the conveyor belt 1 rotates one revolution, the motor 54 stops rotating and controls the telescopic rod 52 to retract, so that the drive gear 51 cannot mesh with the rack 34 and the second row of teeth 42, thus preventing the left baffle 31 and the right baffle 41 from continuing to move after reaching their maximum moving positions.

[0028] like Figure 3 and Figure 7 As shown, first grooves 211 are respectively formed at both ends of the top of the left base 21. The protrusion at the bottom of the left baffle 31 slides inside the first grooves 211. A second groove 212 is formed on one side of the left base 21. The protrusion on the inner side of the rack 34 slides inside the second groove 212. The first groove 211 is to provide sliding space for the protrusion at the bottom of the left baffle 31, and the second groove 212 is to provide sliding space for the protrusion on the inner side of the rack 34.

[0029] like Figure 6 As shown, the top two ends of the right base 22 are respectively provided with a third groove 221. The bottom protrusion of the right baffle 41 slides inside the third groove 221. The third groove 221 is designed to provide sliding space for the bottom protrusion of the right baffle 41. The third groove 221 is the same size as the first groove 211.

[0030] Working principle: When the conveyor belt 1 starts conveying, the output shaft of the motor 54 rotates the drive gear 51 clockwise, and the rotational speed of the drive gear 51 is greater than the moving speed of the conveyor belt 1. This causes the drive gear 51 to drive the second row of teeth 42 to move to the right, thereby increasing the space on the right side. When the conveyor belt 1 transmits the left sliding component 3 to the rotating component 5, the rack 34 meshes with the drive gear 51. The drive gear 51 drives the rack 34 to move to the right. At the same time, the rack 34 drives the first gear 33 to rotate counterclockwise, thereby causing the left baffle 31 to move to the left, which also increases the space on the right side. After the conveyor belt 1 rotates one revolution, the motor 54 stops rotating and controls the telescopic rod 52 to retract, so that the drive gear 51 cannot mesh with the rack 34 and the second row of teeth 42. This prevents the left baffle 31 and the right baffle 41 from continuing to move after reaching their maximum moving position. Since the increased space on both sides is the same, the packaging box is still located in the center position of the left baffle 31 and the right baffle 41 when it falls.

[0031] Embodiments of the present invention have been shown and described. Those skilled in the art will be able to make various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
