Description

Technical Field

[0001] This utility model relates to the field of cardboard box nailing machine technology, specifically a cardboard box nailing machine. Background Technology

[0002] Carton staplers are high-efficiency devices used in the packaging industry for quickly stapled cartons. Their working principle is similar to a stapler, using toothed joints as the sealing plate. This equipment is simple to operate, lightweight, and features high wear resistance, smooth sealing, and reliable fastening. It effectively reduces labor intensity and improves sealing efficiency. Widely used in logistics, e-commerce, food, and other fields, it is a key piece of equipment for carton sealing, characterized by high speed, high stability, and convenient maintenance.

[0003] During carton nailing, operators need to manually pinch the two sides of the carton's edge to complete the nailing process. This manual intervention means that the accuracy of the edge sealing distance is highly dependent on the operator's experience and skill level, easily leading to problems such as nailing deviation and uneven sealing. Due to the lack of a unified positioning standard, cartons from different batches or completed by different operators often have differences in edge sealing dimensions.

[0004] This instability can cause a series of problems in subsequent automated packaging processes. When cartons are loaded and enter the automatic carton sealing machine for sealing, the equipment has high requirements for the dimensional accuracy of the cartons. If the stapling positions of the cartons are inconsistent or the sealing distance exceeds the allowable tolerance range, the automatic carton sealing machine may not be able to accurately identify the sealing position, or even cause carton jamming, loose sealing, or equipment malfunction, affecting the overall packaging efficiency and quality.

[0035] This utility model provides limiting telescopic rods 23 on both sides of the first electric push rod 16, the second electric push rod 17, the third electric push rod 21, and the fourth electric push rod 22.

[0036] This utility model has an industrial inspection camera 24 installed on the support frame 15 in conjunction with the nail head 5. The industrial inspection camera 24 can accurately detect the distance from the nail to the sealing edge of the carton, thereby improving the accuracy of sealing the edge when nailing the carton.

[0037] In summary, the working principle and specific workflow of this utility model are as follows:

[0038] When using this utility model, after the cardboard box is initially formed, it is placed on the support plate 2, and the end of the box to be nailed is located on the conveyor roller 3, and the position where the box nailing operation is to be performed is located below the nail head 5.

[0039] Meanwhile, the inner limiting roller 8 is located inside the formed carton and is used to limit the inward extrusion of the formed carton.

[0040] The third electric push rod 21 controls the outer limit frame 9 to drive the outer limit roller 10 to move, so that the outer limit roller 10 squeezes the carton from the outside to the inside, thereby cooperating with the inner limit roller 8 to accurately adjust the connection position when the carton is nailed and sealed, and achieves precise limit conveying in the subsequent conveying process.

[0041] Then, the second electric push rod 17 is controlled to drive the pressing frame 18 to descend, so that the pressing roller 19 descends and presses against the joint end of the carton that needs to be nailed, thereby cooperating with the conveyor roller 3 to achieve pressing of the working area.

[0042] Then, start the drive motor 12. The drive motor 12 can control the rotation of the corresponding drive shaft 11. The drive shaft 11 and the synchronous belt drive structure 13 can control the synchronous rotation of other drive shafts 11, thereby realizing the synchronous rotation of the conveyor roller 3. The cooperation between the conveyor roller 3 and the pressure roller 19 can realize the stable and automatic conveying of the carton during the nailing operation.

[0043] During this process, the inner limiting roller 8 will cooperate with the outer limiting roller 10 to achieve stable positioning of the side conveying position of the carton, so that the nailing connection end of the carton remains precisely fitted.

[0044] During the above process, the first electric push rod 16 controls the nail head 5 to descend, so that the nail head 5 cooperates with the nail box seat 4 to perform nailing operation on the connecting end of the conveyed carton;

[0045] During this process, the sealing distance at the nailing joint of the carton can be monitored by an industrial inspection camera 24 to ensure operational accuracy;

[0046] After the operation is completed, the pressure roller 19 and the outer limit roller 10 can be released from their positions on the carton, and the conveyor roller 3 can be rotated in the reverse direction to achieve automatic unloading of the carton after it is nailed.

[0047] This invention enables automatic alignment and limiting of the carton connection end during carton nailing operations, and ensures stable automatic conveying during the transport process. This invention only requires manual initial loading operations, and can automatically calibrate the nailing position in subsequent processes. It solves the technical problems of high dependence on human experience and poor standardization in the existing manual pinching and alignment methods, and improves the production standardization of carton nailing operations.
