[0002] In the modern packaging industry, cardboard boxes have become the main carrier for product transportation packaging due to their advantages such as low cost, environmental friendliness, and recyclability. As a key piece of equipment in cardboard box processing, the performance of the carton stapling machine directly affects the cardboard box production efficiency and the quality of the finished product.

[0003] Currently, most carton staplers on the market are semi-automatic or manually operated. In actual production, operators need to manually position the carton blanks on the stapler table first, and then manually push the stapler head or adjust the position of the carton to complete the stapler operation. In addition, during manual operation, the movement of the stapler head can easily cause accidental hand contact, posing a safety hazard. Furthermore, the stapler head has insufficient flexibility in displacement, a narrow range of applications, and low efficiency. Therefore, it is necessary to design a carton stapler to solve the above problems. Utility Model Content

A slider is movably connected to the outer surface of the first screw. Two sliders are provided, and a displacement plate is fixedly connected to the top of the two sliders. The second drive motor is fixedly connected to the front left side of the base plate.

[0008] Preferably, a drive motor three is fixedly connected to the upper right end of the displacement plate, the output end of the drive motor three passes through the displacement plate and is fixedly connected to a screw two, the upper left and upper right walls of the displacement plate are jointly fixedly connected to a limit rod, the outer surface of the screw two is threaded with a mounting plate, the lower front end of the mounting plate is inserted and fixedly connected to a lifting stapling head device, and the drive motor three is fixedly connected to the upper right end of the displacement plate.

[0009] Preferably, the rear end of the screw is movably connected to the rear wall of the slide groove on the left side via a bearing, and the two sliders are symmetrically distributed in the slide groove, and the sliders slide longitudinally in the slide groove.

[0010] Preferably, the left end of the second screw is movably connected to the upper part of the left wall of the displacement plate via a bearing, the second screw is located directly below the limiting rod, and the mounting plate slides along the length of the limiting rod.

[0011] Preferably, the limiting block slides laterally within the limiting groove three, the upright plates are arranged in pairs and slidably connected within the limiting groove one, the two centering plates have the same structure and are relatively distributed, and the multiple rubber strips are arranged at equal intervals along the width of the centering plate.

[0020] Please see Figure 1-5 This utility model provides a technical solution: A carton stapling machine, such as Figure 1 , Figure 2 and Figure 3 As shown, the binding table 1 is fixedly connected to the upper end of the binding table 1. The upper left and upper right sides of the upper end of the base plate 8 are both provided with sliding grooves 3. The upper middle part of the base plate 8 is provided with two limiting grooves 7. The upper rear part of the base plate 8 is provided with limiting groove 11 and groove 9 respectively. The limiting groove 11 is located to the left of the groove 9. The left wall of the groove 9 is fixedly connected with a cylinder 5. The output end of the cylinder 5 passes through the base plate 8 and is fixedly connected with an L-shaped support plate 6. The front left part of the base plate 8 is fixedly connected with a displacement mechanism 4. The lower middle part of the base plate 8 is provided with a groove 10. The upper middle part of the binding table 1 is provided with a limiting groove 12. The centering support mechanism 2 is movably connected to the base plate 8. The vertical section of the L-shaped support plate 6 is slidably connected in the limiting groove 11, and the horizontal section of the L-shaped support plate 6 is located above the base plate 8.

[0021] Please see Figure 3The support organization 2 includes a drive motor 21. The output of the drive motor 21 passes through the binding table 1 and is fixedly connected to a rotating disk 22. The top two sides of the rotating disk 22 are movably connected to two sliding plates 23. The two sliding plates 23 are staggered left and right. The bottom of the other side of each sliding plate 23 is movably connected to a connecting plate 24. The lower middle of each connecting plate 24 is fixedly connected to a limit block 28. The upper front and upper rear of each connecting plate 24 are fixedly connected to upright plates 25. The two upright plates 25 on the left and right sides are connected to each other. Two centering plates 26 are fixedly connected to the two side upright plates 25. Two centering plates 26 are provided and are symmetrically distributed from left to right. Multiple rubber strips 27 are fixedly connected to the opposite surfaces of the two centering plates 26. The drive motor 21 is fixedly connected to the upper wall of the binding table 1. The limiting block 28 slides laterally in the limiting groove 12. The upright plates 25 are arranged in pairs and are slidably connected in the limiting groove 7. The two centering plates 26 have the same structure and are distributed opposite each other. Multiple rubber strips 27 are arranged at equal intervals along the width of the centering plate 26.

[0022] Through the above scheme: When the centering support mechanism 2 is working, the drive motor 21 starts and drives the rotating disk 22 to rotate. The rotating disk 22 drives the two reciprocating plates 23, which are distributed in a staggered manner, to move. The reciprocating plates 23 drive the connecting plate 24 to move, so that the limiting block 28 at the lower end of the connecting plate 24 slides laterally in the limiting groove 12. At the same time, the upright plates 25 at the front and rear of the upper end of the connecting plate 24 slide in pairs in the limiting groove 7, thereby driving the two centering plates 26, which are symmetrically distributed and have the same structure, to move relative to each other. Multiple rubber strips 27, which are equidistantly arranged along the width on the opposite surface of the centering plates 26, are used to center and support the carton. Their function is to ensure that the carton is supported during the nailing process. The rubber strips 27 can also prevent damage to the surface of the carton. There is no need for manual handling, making the use of the entire nailing machine safer.

[0023] Please see Figure 4The displacement mechanism 4 includes a second drive motor 41. The output end of the second drive motor 41 passes through the base plate 8 and is fixedly connected to a first screw 42. A slider 43 is movably connected to the outer surface of the first screw 42. Two sliders 43 are provided, and the tops of the two sliders 43 are fixedly connected to a displacement plate 44. The second drive motor 41 is fixedly connected to the front left side of the base plate 8. A third drive motor 46 is fixedly connected to the upper right side of the displacement plate 44. The output end of the third drive motor 46 passes through the displacement plate 44 and is fixedly connected to a second screw 47. A limit rod 45 is fixedly connected to the upper left and upper right sides of the displacement plate 44. The outer surface of rod 47 is threaded with a mounting plate 48. The lower front end of the mounting plate 48 is fixedly connected to a lifting head device 49. The drive motor 46 is fixedly connected to the upper right end of the displacement plate 44. The rear end of screw 42 is movably connected to the rear wall of the slide groove 3 on the left side through a bearing. Two sliders 43 are symmetrically distributed in the slide groove 3, and the sliders 43 slide longitudinally in the slide groove 3. The left end of screw 47 is movably connected to the upper left wall of the displacement plate 44 through a bearing. Screw 47 is located directly below the limiting rod 45. The mounting plate 48 slides along the length of the limiting rod 45.

[0024] Through the above scheme: When the displacement mechanism 4 is working, the second drive motor 41 starts and drives the first screw 42 to rotate, causing the two sliders 43, which are symmetrically distributed on the left and right, to slide longitudinally in the slide groove 3, thereby driving the displacement plate 44 at the top of the slider 43 to move longitudinally. At the same time, the third drive motor 46 starts and drives the second screw 47 to rotate. Since the second screw 47 is located directly below the limiting rod 45 and its left end is movably connected to the upper part of the left plate wall of the displacement plate 44 through a bearing, the mounting plate 48, which is threadedly connected to the second screw 47, slides laterally along the limiting rod 45, thereby driving the lifting and stapling head device 49 at the lower front of the mounting plate 48 to move in both longitudinal and transverse directions. Its function is to drive the lifting and stapling head device 49 to any position where the carton needs to be stapled, which improves the applicability of the carton stapling machine and increases the stapling efficiency.

[0025] It should be noted that this utility model is a carton nailing machine. When the carton nailing machine is working, the drive motor 21, drive motor 41, drive motor 46 and cylinder 5 are first connected to the power supply. When it is necessary to nail the carton, the carton is placed on the base plate 8. The drive motor 21 starts and drives the rotating disk 22 to rotate. The rotating disk 22 drives the two reciprocating plates 23 to move through the rotation. The reciprocating plates 23 drive the connecting plate 24 to move through the rotation, so that the limiting block 28 slides laterally in the limiting groove 12. At the same time, the upright plate 25 slides in the limiting groove 7, thereby driving the two centering plates 26 to move relative to each other. Multiple rubber strips 27 support and center the carton. Then, cylinder 5 is activated, and its output end pushes the L-shaped support plate 6 to slide in the limiting groove 11, so that the horizontal section of the L-shaped support plate 6 supports and limits the rear of the carton. Then, drive motor 41 is activated to drive screw 42 to rotate, so that two sliders 43 slide longitudinally in the sliding groove 3, thereby driving the displacement plate 44 to move longitudinally to the appropriate position. Then, drive motor 46 is activated to drive screw 47 to rotate, so that the mounting plate 48 slides laterally along the limiting rod 45, thereby driving the lifting and stapling head device 49 to move to the position where the carton needs to be stapled. Finally, the stapling operation of the carton is completed by the lifting and stapling head device 49.
