Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging technology, and in particular to a flip-top latch mechanism for packaging boxes. Background Technology
[0002] Currently, most small and medium-sized enterprises still use manual methods to complete the flap insertion operation of packaging boxes: workers need to manually position the packaging box, bend the two flaps on both sides to the specified angle, and then press down the cover to insert the flaps into the box to complete the sealing. This method has obvious shortcomings: on the one hand, manual operation relies on experience, and the bending angle is prone to deviation, resulting in the flaps not fitting tightly or the packaging box being damaged, and the sealing quality is not stable; on the other hand, manual operation is inefficient, difficult to match the rhythm of assembly line production, and long-term repetitive operation can easily cause workers to get tired, further increasing the rate of operational errors. Utility Model Content
[0003] To address the technical problems existing in the background art, this utility model proposes a packaging box flip-top tongue mechanism.
[0004] This utility model discloses a packaging box flap mechanism, including an equipment cabinet. A frame and a bracket are installed at the top of the equipment cabinet. The bracket supports the packaging box. A first cylinder is installed inside the equipment cabinet. The telescopic end of the first cylinder extends to the upper part of the equipment cabinet and is equipped with a lifting plate to support the cover of the packaging box. A second cylinder is installed at the top of the frame. A pressure plate is installed at the telescopic end of the second cylinder to bend the cover of the packaging box downwards. A third cylinder is installed at the top of the frame and on both sides of the second cylinder. The telescopic end of the third cylinder is equipped with a side pressure plate to bend the flap of the packaging box downwards.
[0005] Furthermore, a material removal module is installed at the top of the equipment cabinet. The drive end of the material removal module is located below the support, so that after the packaging box is lifted, it can move the packaging box out from the inside of the support.
[0006] Furthermore, the material removal module includes a linear drive module installed on the top of the equipment cabinet, the drive end of the linear drive module is equipped with a fourth cylinder, and the telescopic end of the fourth cylinder is equipped with a receiving platform.
[0007] Furthermore, a fifth cylinder is installed on both sides of the frame, and a clamp is installed on the telescopic end of the fifth cylinder to fix the packaging box when it is bent.
[0008] Furthermore, the bracket is configured as symmetrically distributed "L"-shaped angle irons, and the packaging box is placed between the "L"-shaped angle irons.
[0009] Further, the lower pressing plate is arranged in a "凵"-shaped structure, the side pressing plate is arranged in an "L"-shaped structure, and the bottom part is inclined toward the outer side.
[0010] Beneficial effects of the present utility model: the mechanism can automatically complete the whole process of packing box positioning, tongue plate bending, cover plate downward pressing and inserting, and moving out after processing, without manual participation. It can not only avoid bending angle deviation caused by differences in manual experience, effectively ensure the tight insertion of the tongue plate, reduce damage to the packing box, and improve the stability of packaging quality, but also significantly improve packaging efficiency, adapt to the pace of assembly line production, while avoiding fatigue and operational errors caused by long-term repeated operations of staff, and effectively solve the pain points of quality and efficiency of the existing manual packaging method.

Detailed Description of Embodiments
[0013] Referring to Figure 1-4 , a packing box flap inserting and tongue inserting mechanism proposed by the present utility model comprises an equipment cabinet 1, a frame body 101 and brackets 8 are installed at the top end of the equipment cabinet 1, the brackets 8 are arranged as symmetrically distributed "L"-shaped angle irons, and a packing box 12 is placed between the "L"-shaped angle irons to realize bearing and positioning of the packing box 12. In order to complete the bending operation of the tongue plate 122 in the packing box 12, a first cylinder 2 is installed inside the equipment cabinet 1, the telescopic end of the first cylinder 2 extends to the upper part of the equipment cabinet 1 and is installed with a jacking plate 3. When the piston rod of the first cylinder 2 extends out, the jacking plate 3 jacks up upward, which can support the cover plate 121 of the packing box 12 and prevent the cover plate 121 from bending downward along with the tongue plate 122 during the downward bending process of the tongue plate 122. A second cylinder 4 is installed at the top of the frame body 101, the telescopic end of the second cylinder 4 is installed with the lower pressing plate 5 of "凵"-shaped structure. After the tongue plate 122 is bent downward by 90°, the piston rod of the second cylinder 4 extends out, the lower pressing plate 5 moves downward, which can stably bend the whole cover plate 121 and the tongue plate 122 downward by 90°; To address the bending requirement of the tongue plate 122 of the packaging box 12, a third cylinder 6 is installed on the top of the frame body 101 and on both sides of the second cylinder 4. An "L"-shaped side pressure plate 7 is installed at the telescopic end of the third cylinder 6. The bottom of the side pressure plate 7 is inclined outward. This inclined design can guide the tongue plate 122 to bend smoothly and avoid scratching the packaging box 12. When the piston rod of the third cylinder 6 extends, the side pressure plates 7 on both sides move downward synchronously, bending the tongue plate 122 downward by 90°. When it cooperates with the bent cover plate 121, the tongue plate 122 will be inserted into the interior of the packaging box 12, completing the tongue insertion action. To ensure the stability of the packaging box 12 during bending, a fifth cylinder 10 is installed on both sides of the frame 101, with a clamping plate 11 installed at its telescopic end. Before bending the cover plate 121 and tongue plate 122, the piston rod of the fifth cylinder 10 extends, driving the clamping plate 11 to move towards the packaging box 12 until it clamps the packaging box 12, preventing it from shifting during bending and ensuring bending accuracy. To achieve automatic removal of the packaged box 12 after processing, a material removal module 9 is installed at the top of the equipment cabinet 1. The material removal module 9 includes a linear drive module 91, a fourth cylinder 92, and a receiving platform 93. The linear drive module 91 is installed at the top of the equipment cabinet 1, with the fourth cylinder 92 installed at its drive end and the receiving platform 93 installed at the extension end of the fourth cylinder 92. When the flip-top latch is completed, the piston rod of the fourth cylinder 92 extends, and the receiving platform 93 lifts the packaged box 12 upward, causing it to detach from the support of the bracket 8. Then, the linear drive module 91 starts, driving the fourth cylinder 92 and the receiving platform 93 to move, thereby removing the packaged box 12 from inside the bracket 8 to the designated position, completing the entire processing flow.
[0014] The work process is as follows: The packaging box 12 is placed on the support 8. Then, the piston rod of the fifth cylinder 10 extends, causing the clamping plate 11 to move towards the packaging box 12 until it is clamped. Immediately afterwards, the piston rod of the first cylinder 2 extends, and the lifting plate 3 moves upward, which can apply an upward supporting force to the cover plate 121 of the packaging box 12 (as shown in the attached diagram). Figure 4 (As shown in the left figure), then the piston rod of the third cylinder 6 extends, pushing the side pressure plate 7 downward. During the downward movement of the side pressure plate 7, the tongue plates 122 on both sides will bend downward by 90° (as shown in the attached figure). Figure 4 (As shown in the intermediate diagram), finally, the piston rod of the first cylinder 2 retracts, the lifting plate 3 moves downward to reset, releasing the support for the cover plate 121. Then, the piston rod of the second cylinder 4 extends, pushing the lower pressure plate 5 downward. During the downward movement, the cover plate 121 bends downward by 90°, and at the same time, the tongue plate 122 enters the interior of the packaging box 12 to engage, thus completing the sealing of the packaging box 12, i.e., completing the tongue insertion action (as shown in the attached diagram). Figure 4(As shown in the right figure), after completion, the piston rod of the fourth cylinder 92 extends, and the receiving platform 93 lifts the packaging box 12 upward, causing it to detach from the support of the bracket 8. Then, the linear drive module 91 starts, driving the fourth cylinder 92 and the receiving platform 93 to move, thereby moving the packaging box 12 out of the bracket 8, ready to be picked up.
