Description

Technical Field

[0001] The utility model belongs to the technical field of box nailing machines, and particularly relates to a limiting mechanism of a box nailing machine. Background Art

[0002] A stapler is a mechanical device specially used for sealing cartons. Its working principle is similar to that of an ordinary stapler, but it is designed with tiger teeth as pads to adapt to the carton material and ensure the stability of the sealing. Stitchers are widely used in the carton packaging industry to quickly and efficiently complete the bottom or top sealing operations of cartons, improve production efficiency and sealing quality. Regarding the limiting mechanism of the stapler, it is a key component in the equipment, which is used to ensure that the carton is in the correct position when entering the stapling process to avoid the nail needle from hitting the deviation or damaging the carton. The limiting mechanism is usually implemented by mechanical, photoelectric or pneumatic means to ensure that the carton is accurately aligned in the fixed area. The existing limiting mechanism of the stapler can only limit the upper end of the carton, but not the front and back sides of the carton, which will result in inaccurate positioning.

[0003] For example, the utility model with announcement number CN212124348U discloses a limiting mechanism for a manual carton stapler. In this patent scheme, it can only limit the upper end of the carton for stapling, but cannot limit the front and back sides of the carton. The lack of side limiting may cause the carton to move laterally, causing the stapling position to deviate from the center, affecting the aesthetics and stability of the carton sealing. The operator needs more time to manually adjust the position of the carton to compensate for the problem of insufficient limiting, thereby reducing production efficiency. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides a limiting mechanism for a carton nailing machine, which can not only limit the upper end of the carton, but also limit the front and back sides of the carton. The all-round limiting mechanism can ensure the accurate positioning of the carton in all dimensions, improve the accuracy and consistency of carton sealing, and the automatic limiting mechanism can reduce manual intervention, speed up the production process, and improve the overall production efficiency.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a limiting mechanism of a nailing machine, including a placing plate, a fixed plate is arranged on the left side of the upper end of the placing plate, two limiting plates are slidingly arranged inside the placing plate, the front and rear positions of the two limiting plates correspond, a moving mechanism for driving the two limiting plates to move is arranged on the relatively inner side surfaces of the two limiting plates, a downward pressing limiting mechanism is arranged on the opposite outer sides of the two limiting plates, the moving mechanism includes rotating seats respectively arranged on the relatively inner side surfaces of the two limiting plates, connecting frames are rotatably connected inside the two rotating seats, a rotating frame is rotatably arranged between the right sides of the two connecting frames, a frame plate is arranged at the lower end of the placing plate, and a rotating device inside the frame plate is arranged A screw rod is arranged, and the rotating frame is threadedly connected to the screw rod. An electric drive unit 1 for driving the screw rod to rotate is arranged on the left side of the frame plate. The electric drive unit 1 includes a motor arranged on the left side of the frame plate, and the output shaft of the motor is connected to the left end of the screw rod through a coupling. The downward pressure limit mechanism includes pressure plates respectively slidably arranged inside the two limit plates, and the upper ends of the two pressure plates are respectively provided with connecting plates, and the lower ends of the two pressure plates are bonded with buffer pads. Electric drive units 2 for driving the pressure plates to move are respectively arranged on the opposite outer sides of the two limit plates, and the electric drive unit 2 includes electric push rods respectively arranged on the opposite outer sides of the two limit plates, and the telescopic ends of the two electric push rods are respectively connected to the lower ends of adjacent connecting plates.

[0006] As a further improvement of the utility model, a control panel is arranged on the front side of the placement plate, and the motor and the electric push rod are both electrically connected to the control panel.

[0007] As a further improvement of the utility model, four mounting plates are welded and fixed to the lower end of the placement plate, and mounting holes are provided inside the four mounting plates.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] First, by installing the placement plate on the nailing machine, and then placing the carton on the placement plate so that the left side of the carton contacts the fixed plate, the control panel is used to control the motor to start running, and the output shaft rotates to drive the lead screw to rotate, so that the rotating frame moves to the right, and the internal connecting frame rotates and contracts to drive the limit plates on the rotating seats on both sides to move closer to each other to limit the front and back sides of the carton.
