[0029] As a preferred embodiment, on the basis of the above structure, further, the spacing adjustment component 4 includes a fixed frame 41, a bidirectional screw rod 42 and a servo motor 43. The fixed frame 41 is fixedly installed on the middle upper end surface of the base plate 1.

The front end outer wall of the fixed frame 41 is fixedly installed with the servo motor 43, and the output end of the servo motor 43 is fixedly connected to the front end of the bidirectional screw rod 42.

[0030] In this embodiment, the servo motor 43 is used to control the rotation of the bidirectional lead screw 42, which can conveniently adjust the distance between the two movable frames 5, facilitating the nail box processing requirements for cartons of different sizes.

[0031] As a preferred implementation manner, on the basis of the above structure, further, three fixing blocks 12 are fixedly arranged at equal intervals along the length direction of the bottom end of the movable frame 5. The three fixing blocks 12 respectively correspond to the two limiting frames 2 and the fixing frame 41. The two fixing blocks 12 located at the left and right ends of the bottom plate 1 are respectively engaged and slid in the inner sides of the two limiting frames 2 and are slidably sleeved on the outer sides of the limiting rods 3. The fixing block 12 located in the middle of the bottom plate 1 is threadedly sleeved on the outer side of the bidirectional lead screw 42.

[0032] In this embodiment, through the fixing block 12 and the limiting rod 3 fixed inside the limiting frame 2, the stability of the movable frame 5 during the sliding adjustment process can be improved.

A connecting rod 83 is rotatably sleeved on the outer side of one end of the second horizontal shaft 85. A worm gear 87 is fixedly connected to the other end of the second horizontal shaft 85. The worm gear 87 meshes with the worm 10. The end of the connecting rod 83 away from the second horizontal shaft 85 is rotatably sleeved on the outer side of the first horizontal shaft 81. A second gear 86 is fixedly sleeved on the middle outer side of the second horizontal shaft 85. The first gear 84 and the second gear 86 are always in a meshing state with each other.

[0035] In this embodiment, by starting the drive motor 9 to control the rotation of the worm 10, the worm gear 87 can drive the second horizontal shaft 85 and the second gear 86 to rotate, so that the second gear 86 can drive the first gear 84, the first horizontal shaft 81, and the pressing roller 82 to rotate, cooperating with the conveyor belt 6, facilitating the automatic traction and transmission of the carton, facilitating the nail box processing, and making the automation degree of the device higher.

[0036] As a preferred implementation manner, on the basis of the above structure, further, the centers of the second horizontal shaft 85 and the arc-shaped groove 7 coincide with each other.

[0037] In this embodiment, since the centers of the second horizontal shaft 85 and the arc-shaped groove 7 coincide with each other, when the connecting rod 83 drives the first horizontal shaft 81 to rotate, the first gear 84 and the second gear 86 can always be engaged, facilitating the stable rotation of the first horizontal shaft 81 and the pressing roller 82.

[0038] As a preferred embodiment, on the basis of the above structure, further, a tension spring 11 is fixedly connected to the bottom end surface of the connecting rod 83, and the end of the tension spring 11 away from the connecting rod 83 is fixedly connected to the outer wall of the movable frame 5.

[0040] The working principle of the present utility model is as follows:

[0041] During use, first stack the cardboard boxes to be box-nailed and place them above the front and rear conveyor belts 6 as required. The conveyor belt 6 drives the cardboard boxes to move. When the cardboard box passes under the pressing roller 82, the cardboard box can generate an upward extrusion thrust on the pressing roller 82, enabling the pressing roller 82, the first horizontal shaft 81, and the connecting rod 83 to rotate synchronously around the second horizontal shaft 85. At this time, the first horizontal shaft 81 moves along the arc-shaped groove 7. At the same time, under the pulling force of the tension spring 11, it is convenient for the pressing roller 82 to press the cardboard box above the conveyor belt 6, realizing the stable transmission of the cardboard box. At the same time, start the drive motor 9 to control the rotation of the worm 10 and drive the worm wheel 87, the second gear 86, and the second horizontal shaft 85 to rotate synchronously. Since the first gear 84 and the second gear 86 are always engaged, the first gear 84 can be controlled to drive the first horizontal shaft 81 and the pressing roller 82 to rotate stably, cooperating with the conveyor belt 6 to facilitate stable automatic traction transmission while pressing and positioning the cardboard box. Subsequently, box nailing can be performed through the nail gun head 14. Compared with the comparative document, this device does not require manual pushing, has a simple operation, a higher degree of automation, and also has a significant effect on improving the box-nailing processing efficiency;

[0042] Since the centers of the second horizontal shaft 85 and the arc-shaped groove 7 coincide with each other, when the connecting rod 83 drives the first horizontal shaft 81 to rotate around the second horizontal shaft 85 to adjust the position, the first gear 84 can always be engaged with the second gear 86, facilitating the stable rotation of the driving pressing roller 82. Before box-nailing processing, according to the actual size of the cardboard box to be processed, start the servo motor 43 to control the rotation of the bidirectional lead screw 42, and the two movable frames 5 can be controlled to slide stably in the opposite direction along the limiting rod 3 synchronously, adjusting the distance between the two movable frames 5 to meet the box-nailing processing requirements of cardboard boxes of different sizes;

[0043] It should be specifically noted that the conveyor belt 6 and the nail gun head 14 in this device are exactly the same as the nail gun head in the comparative document. The specific internal structure and working principle thereof both adopt extremely mature existing technical means, and this part is not the key improvement direction and protection scope of this case. Therefore, it will not be elaborated further.

[0044] The above are only the preferred specific embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model; any equivalent changes, modifications, substitutions and variations made by those skilled in the art in this technical field based on the concept of the present utility model on the basis of the existing technology through logical analysis, reasoning or limited experiments shall fall within the protection scope determined by the claims.
