Description

Technical Field

[0001] This utility model relates to the technical field of cardboard box processing equipment. Background Technology

[0002] In the modern packaging industry, cardboard boxes have become one of the most widely used packaging materials due to their excellent cushioning, processability, and environmental friendliness, and market demand continues to grow. Cardboard box production equipment typically includes a paper feeding unit, printing unit, creasing unit, slotting unit, die-cutting unit, folding and gluing unit, etc. All components work in a unified and coordinated manner under the action of the power system and transmission system to complete a series of processing operations such as paper feeding, multi-stage printing, creasing, slotting, die-cutting, folding, and gluing.

[0003] In the cardboard box production process, the stapling stage is a crucial node determining production efficiency. Currently, most stapling equipment on the market adopts a single production line configuration, and this linear production mode has obvious drawbacks. According to industry statistics, traditional single-linear stapling equipment can only produce about 80-100 boxes per minute when producing complex-structured cardboard boxes. Faced with explosive order demand, existing equipment is insufficient to meet daily production targets. To address the shortcomings of existing technologies, this utility model proposes a cardboard layering mechanism, aiming to break through the production bottleneck of traditional stapling equipment. By layering the cardboard, the stapling process is optimized, production efficiency is improved, and the efficiency problem of the stapling stage in current cardboard box production is effectively solved. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a cardboard layer conveying mechanism to solve the problem of slow production speed of single-layer nailing boxes in the above background.

[0005] The technical solution adopted by this utility model is:

[0006] A carton layer conveying mechanism includes: a frame 1, an upper conveying device 2, a lower conveying device 3, a toggle device 4, a sensor assembly 5, and a drive motor; the conveying device 2 includes an upper first conveyor belt 21, an upper second conveyor belt 22, a lower first conveyor belt 31, and a lower second conveyor belt 32; the toggle device 4 is fixed to the frame 1 via a rotating shaft 41, the rotating shaft 41 is connected to a servo drive motor, a toggle block 42 is mounted on the rotating shaft 41, and the sensor assembly 5 is mounted on the frame 1.

[0007] Preferably, the push block 42 is provided with a sensor assembly 5, which is fixed on the frame 1 to detect whether the cardboard is being passed. The control system controls the rotation position and rotation direction of the push block 42 and limits the rotation direction of the push block 42 to ensure that the push block pushes the cardboard in a preset direction.

[0008] Preferably, the plurality of toggle blocks 42 are spaced apart along the axial direction of the rotating shaft 41, which is rotatably mounted on the frame 1 and connected to the servo drive motor.

[0009] Preferably, the upper first conveyor belt 21, the upper second conveyor belt 22, the lower first conveyor belt 31, and the lower second conveyor belt 32 have the same structure, each including an annular conveyor belt 24 disposed on a drive roller 23. The drive roller 23 is rotatably mounted on the frame 1 to support and drive the conveyor belt 24 to operate.

[0010] Preferably, the upper first conveyor belt 21 and the upper second conveyor belt 22 are arranged parallel to each other on the frame 4, forming an upper conveying gap between them; the lower first conveyor belt 31 and the lower second conveyor belt 32 are arranged parallel to each other on the frame 1, forming a lower conveying gap between them.

[0011] Compared to existing technologies, the advantages of this invention are as follows: This invention uses a two-layer conveyor system to process cardboard in layers, which are then transported to a subsequent double-layer stapling device for simultaneous processing. These two stapling devices are horizontally arranged, connecting to the ends of the upper and lower conveyor systems respectively. After the cardboard is conveyed from different layers, it directly enters the corresponding stapling station. Compared to the traditional single-layer conveyor line stapling mode, this parallel processing method directly increases production efficiency from 80-100 pieces per minute to 180-210 pieces per minute. This increased efficiency shortens the overall carton production cycle, easily handling surges in demand during e-commerce promotions and holiday orders, giving businesses a valuable time advantage in fierce market competition.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0020] Reference Figs. 1-3 This utility model provides a technical solution: a cardboard layering conveying mechanism, including a frame 1; the frame 1 serves as the supporting foundation of the equipment, providing installation positions for other components; the upper conveying device 2 is inclinedly installed on the frame 1, and the lower conveying device 3 is horizontally installed on the frame 1 to realize the upper cardboard layering and lower layering; the upper conveying device 2 and the lower conveying device 3 have the same structure and are used to convey cardboard; in the upper conveying device 2, the transmission roller 23 is installed on the frame 1; a servo drive motor is provided on the outside of the transmission roller 23; the external movement of the output end of the servo drive motor is connected to the transmission roller 23; the rotating shaft 41 is rotatably installed on the frame 1; a plurality of levers 42 are respectively installed on the left and right sides of the rotating shaft 41 for layering the cardboard; the sensor assembly 5 is installed on the frame 1 to detect whether the cardboard passes through.

[0021] In this embodiment, multiple levers 42 are mounted on a rotating shaft 41, which uses a servo drive motor as a power source. The servo drive motor of the rotating shaft 41 is connected to the control system. According to the preset program and the signal fed back by the sensor component 5, the rotation angle of the rotating shaft is precisely controlled, which can accurately control the conveying position, ensure the stability and accuracy of the cardboard conveying, and provide a reliable foundation for subsequent operations such as nailing boxes.

[0022] In this embodiment, the upper and lower conveyor belts have the same structure. The drive roller 23 is rotatably mounted on the frame 1. The conveyor belt 24 is mounted on the drive roller 23 to form the upper first conveyor belt 21. The upper second conveyor belt 22 has the same structure as the upper first conveyor belt 21, but uses a smaller drive roller, which is mounted parallel to the lower part of the upper first conveyor belt 21 and is rotatably mounted on the frame 1. The upper first conveyor belt 21 and the upper second conveyor belt 22 use servo drive motors as power sources. The upper first conveyor belt 21 and the upper second conveyor belt 22 have the same speed but opposite directions. A conveying gap is formed between the upper first conveyor belt 21 and the upper second conveyor belt 22. The cardboard is conveyed in the gap to ensure the stability and accuracy of the conveying, providing a reliable foundation for the subsequent nailing operation.

[0023] The working principle of the above technical solution:

[0024] This equipment adopts a control system with a programmable logic controller (PLC) as its core, combined with various sensors and motor drivers, to achieve precise control of each component.

[0025] During production, when the cardboard enters the layering mechanism, the rotating shaft 41, driven by a servo motor, rotates downwards, causing the cardboard to be conveyed between the upper first conveyor belt 21 and the upper second conveyor belt 22. Once the sensor assembly 5 detects that the cardboard has completely passed through, the rotating shaft 41 drives the toggle block 42 to rotate upwards, at which point the next cardboard sheet will enter the gap between the lower first conveyor belt 31 and the lower second conveyor belt 32, completing the layered conveying of the cardboard. Two subsequent sets of stapling equipment are horizontally arranged, connecting to the ends of the upper and lower conveying devices respectively. After the cardboard is delivered from different levels of the conveying devices, it directly enters the corresponding stapling equipment station. This achieves layered conveying of the cardboard, improving production efficiency.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
