Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, and in particular to a folding device for automated cardboard box production. Background Technology

[0002] Folding devices for automated cardboard box production play a crucial role in the modern packaging industry as key equipment in the cardboard box manufacturing process. Utilizing advanced automation technology, these devices efficiently and precisely fold flat cardboard box blanks into finished boxes of specific shapes and sizes, significantly improving the efficiency and quality of cardboard box production. The actual cardboard box production process typically involves the following key components:

[0003] 1. Conveying mechanism: It is responsible for steadily and continuously conveying the flat carton blanks to be folded to the folding area. It has high-precision speed control and positioning functions to ensure the accuracy of the blanks' position during the conveying process.

[0004] 2. Power System: Provides power support for the entire folding device. Common power sources include motors, hydraulic systems, or pneumatic systems. The power system can provide stable and adjustable power output according to different folding process requirements.

[0005] 3. Control System: As the "brain" of the folding device, the control system precisely controls and coordinates the entire folding process through preset programs and instructions to achieve automated operation. It also has real-time monitoring and fault diagnosis functions to ensure the stable operation of the equipment.

[0006] 4. Folding molds: According to different carton shapes and size requirements, corresponding folding molds are designed and manufactured. The molds act directly on the carton blanks to complete the folding action. Their precision and quality directly affect the forming effect of the carton.

[0007] Currently, various types of folding devices exist on the market to achieve efficient cardboard box folding. Some manufacturers use semi-automatic folding equipment, requiring manual assistance for some operations. While this method improves production efficiency to some extent, it still relies heavily on manual labor and is prone to human error. Other manufacturers use traditional fully automatic folding devices with fixed guide plate spacing, limiting their production to specific cardboard box sizes and lacking flexibility. Still other manufacturers offer folding devices with poor guiding accuracy, resulting in inconsistent cardboard box folding quality.

[0008] However, the existing folding device implementations still have the following problems: In terms of automation, semi-automatic equipment cannot completely eliminate manual intervention, which limits the further improvement of production efficiency. For fully automatic equipment with fixed guide plate spacing, when different sizes of cartons need to be produced, the entire guide system or equipment must be replaced, which is cumbersome and costly. Folding devices with insufficient guidance accuracy are prone to causing shape deviations and uneven edges of the folded cartons, which seriously affect the quality and subsequent use of the cartons. In response to these problems, this application proposes a solution: designing an automated folding device for carton production with a high degree of automation, adjustable guide plate spacing, and precise guidance. This device is easy to operate and can quickly adapt to the production needs of cartons of different sizes. Through precise guidance, it ensures a high degree of consistency in the folding quality of the cartons, effectively improving the overall efficiency and quality of carton production.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the cylinder is started, its piston will drive the fixed strip to move together. The movement of the fixed strip will drive the two guide plates to move together.

The overall automated operation can run continuously at a very high speed, unaffected by fatigue, rest or other factors. Compared with manual folding, its work efficiency is greatly improved. It can complete the folding of a large number of cartons in a short time, thereby meeting the needs of large-scale production.

[0016] 2. During the rotation of the screw, the two limiting blocks sleeved on it move relative to each other due to the action of the thread. When the two limiting blocks move, they will drive the two fixed connecting strips to move together. At this time, the distance between the two guide plates can be adjusted. The appropriate distance between the two guide plates can provide accurate guidance for the carton, ensuring that each part of the carton is folded according to the preset path during the downward folding process, avoiding folding deviations or wrinkles, thereby ensuring the forming quality and appearance flatness of the carton.

[0042] Working principle:

[0043] During operation, the feeding mechanism transports the carton to the pressure plate mechanism 2. At this point, the pneumatic cylinder on the pressure plate mechanism 2 pushes the fixed plate downwards. This movement of the fixed plate moves the carton along with it. The downward movement of the carton is guided by two guide plates 3 and two guide plates 8, forming the folded carton. Then, the piston of the cylinder 6 is activated, causing the fixed strip 4 to move. The movement of the fixed strip 4 moves the two guide plates 8. Simultaneously, the motor fixed on the connecting frame 1 starts, transporting the formed carton. This fully automated operation can run continuously at extremely high speeds, unaffected by fatigue or rest. Compared to manual folding, its work efficiency is significantly improved. It can complete the folding of a large number of cartons in a short time, thus meeting the needs of large-scale production. By starting the servo motor 9, its output shaft will drive the fixed screw 14 to rotate. During the rotation of the screw 14, the two limit blocks 11 sleeved on it will move relative to each other due to the thread action. When the two limit blocks 11 move, they will drive the two fixed connecting strips 7 to move together. At this time, the distance between the two guide plates 8 can be adjusted. The appropriate distance between the guide plates 8 can provide accurate guidance for the cartons, ensuring that each part of the cartons is folded according to the preset path during the downward folding process, avoiding folding deviations or wrinkles, thereby ensuring the forming quality and appearance flatness of the cartons.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
