Abstract
Description
Technical Field
[0001] This utility model belongs to the field of carton folding technology, specifically a packaging carton folding processing device. Background Technology
[0002] In the production of packaging cartons, edge folding is one of the key steps. Traditional methods rely heavily on manual operation, which is inefficient and lacks precision, making it difficult to meet the needs of mass production. While some existing automated equipment can improve efficiency, it is complex in structure, expensive, and has poor adaptability to carton sizes. Therefore, we propose a packaging carton edge folding device. Utility Model Content
[0003] To address the problems mentioned in the background art, this utility model provides the following technical solution: a packaging carton folding processing device, comprising a base, a support frame mounted on the base, a driving assembly disposed between the base and the support frame, a conveyor belt mounted on the support frame, a gantry frame mounted on the support frame, the gantry frame disposed on both sides of the conveyor belt, and folding assemblies disposed on both sides of the support frame.
[0004] The folding assembly includes a moving groove, in which a lead screw is disposed. A motor is disposed on the bracket, and the output end of the motor passes through the moving groove and is connected to the lead screw. A connector is disposed on the lead screw, and a locking ring is disposed on the connector. A folding rod is sleeved inside the locking ring.
[0005] Preferably, the folding rod includes a rod body and a folding head. The folding head has a rectangular cross-section and is detachable, allowing users to easily replace folding heads of different shapes or sizes according to their needs, thus improving the adaptability of the device.
[0006] Preferably, the rod is an electrically telescopic rod, which adjusts the length of the folding rod to accommodate cartons of different sizes, thus enhancing the versatility of the lifting device.
[0007] Preferably, the long edge of the folding head has a rounded corner with a radius of 2-3mm to avoid scratching the surface of the carton during the folding process and improve the processing quality.
[0008] Preferably, the gantry is equipped with a photoelectric sensor, which is located at the inlet end of the conveyor belt and electrically connected to the control unit. The photoelectric sensor detects the carton information in real time and automatically adjusts the position and stroke of the folding rod to improve processing accuracy and efficiency.
[0009] Preferably, the conveyor belt surface is provided with anti-slip stripes at intervals to increase the friction between the conveyor belt and the carton and prevent the carton from slipping or shifting during transportation.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] During operation, cartons are placed on a conveyor belt and driven by a drive assembly to transport them to the folding area at a constant speed. When a carton enters the conveyor belt inlet, a photoelectric sensor on the gantry detects the carton's dimensions. The photoelectric sensor transmits the detected carton size information to the control unit. Based on the carton size information transmitted by the photoelectric sensor, the control unit calculates the required stroke and position of the folding rod. The control unit sends a command to the motor, which drives the lead screw to rotate. As the lead screw rotates, the connecting piece moves horizontally along the moving groove, moving the folding rod closer to the carton. After folding is completed, the conveyor belt continues to run, transporting the processed carton to the next process or collection area. The device repeats the above steps, achieving continuous and efficient carton folding processing. It can automatically complete the conveying, folding, and output of cartons, reducing manual operation and significantly improving production efficiency. Attached Figure Description

[0017] The folding assembly includes a moving groove 6, a lead screw 7 is provided in the moving groove 6, a motor 8 is provided on the bracket 2, the output end of the motor 8 passes through the moving groove 6 and is connected to the lead screw 7, a connector 9 is provided on the lead screw 7, a locking ring is provided on the connector 9, and a folding rod 10 is sleeved inside the locking ring.
[0018] The folding rod 10 includes a rod body and a folding head 11. The folding head 11 has a rectangular cross-section and is detachable, allowing users to easily replace it with different shapes or sizes according to their needs, thus improving the adaptability of the device.
[0019] The pole is an electric telescopic pole, and the length of the folding rod 10 can be adjusted by the electric telescopic pole to adapt to different sizes of cartons, thus improving the versatility of the lifting device.
[0020] The long edge of the folding head 11 has a rounded corner with a radius of 2-3mm to avoid scratching the surface of the carton during the folding process and improve the processing quality.
[0021] A photoelectric sensor is installed on the gantry frame 5. The photoelectric sensor is located at the entrance end of the conveyor belt 4 and is electrically connected to the control unit.
