[0002] With the increasing demand for automation in the packaging industry, the closing mechanism of carton forming machines needs to balance efficiency, precision, and versatility. Existing technologies (such as CN106864799A) use cylinders to drive the sealing plate to achieve carton closing. While this structure is simple and avoids the "protruding" area of ​​the carton, it has the following shortcomings:

[0003] Insufficient positioning accuracy: It relies on mechanical structure to directly contact the cardboard box and lacks an active positioning mechanism. It is prone to failure to close the lid or misalignment of creases due to the displacement of the cardboard box position.

[0004] Poor size adaptability: It is only suitable for cardboard boxes of fixed size. When changing specifications, the mechanical structure needs to be adjusted, which is cumbersome and inefficient.

[0005] Weak stability: The cardboard box is easily loosened by gravity or simple clamping when it is fixed by gravity or in a high-speed movement or vibration environment, which affects the quality of the lid closing. Utility Model Content

[0037] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0038] Please refer to Figures 1 to 6 As shown in the figure, an embodiment of the present invention provides a lid closing mechanism for a paper box forming machine, including: a base 1 and a gantry frame 2 fixedly connected to the base 1. A folding component 3 for forming a paper box lid is installed on the gantry frame 2. A placement component 4 for fixing the paper box to be formed is installed on the top of the base 1 and at the position corresponding to the folding component 3. A positioning component 5 for limiting the side of the paper box to be formed is installed on one side of the gantry frame 2. A clamping component 6 for cooperating with the positioning component 5 is installed on the other side of the gantry frame 2.

[0039] By adopting the above technical solutions, the adjustable clamping component 6 enables precise bidirectional positioning of multi-sized cardboard boxes, improving the equipment's versatility; the negative pressure pump 402 and the negative pressure hole 4021 work together to form uniform negative pressure adsorption, enhancing the cardboard box's stability and avoiding the risk of displacement during high-speed movement; the electric cylinder 301 drives the folding plate 3011, which is integrated with the fixing part 302 and the bending part 3021, to simultaneously complete the pressing and folding actions, reducing operation steps and lowering the probability of cardboard box deformation; each module is independently adjustable and compatible with automated control, significantly improving the closing efficiency, yield, and ease of equipment maintenance, meeting the needs of multi-variety, small-batch production.

[0040] To achieve efficient and precise cardboard box folding, in this embodiment: the folding assembly 3 includes an electric cylinder 301 fixedly connected to the gantry 2. A folding plate 3011 is installed on the output end of the electric cylinder 301. The folding plate 3011 consists of a fixing part 302 and a bending part 3021, and the bending part 3021 has an arc-shaped design. The electric cylinder 301 provides high-precision, adjustable-speed linear motion to ensure that the pressing speed and force of the folding plate 3011 are controllable. The arc-shaped design of the bending part 3021 fits the crease curve of the cardboard box, reducing the risk of tearing during folding and improving the yield.

[0041] To stabilize and prevent displacement of the cardboard box, in this embodiment, the placement component 4 includes a placement shell 401 fixedly connected to the top of the base 1, and a negative pressure pump 402 is installed on the side of the placement shell 401. The placement shell 401 has several equally spaced negative pressure holes 4021. The negative pressure pump 402 evenly adsorbs the bottom of the cardboard box through the negative pressure holes 4021, forming a stable negative pressure field. This prevents the cardboard box from shifting due to vibration or airflow disturbance during high-speed closing, and is especially suitable for cardboard boxes made of thin or smooth materials.

[0042] In order to provide a positioning reference for the cardboard box, in this embodiment: the positioning component 5 includes a fixing block 501 fixedly connected to one side of the gantry frame 2, and an abutment plate 5011 fixedly connected to the other end of the fixing block 501. The abutment plate 5011 serves as a rigid positioning reference for one end of the cardboard box, ensuring that the initial position of the cardboard box on the placement shell 401 is accurate, and avoiding creases or misalignment or poor sealing caused by the offset of the cardboard box when closing the lid.

[0043] To achieve rapid positioning and clamping of multi-sized cardboard boxes, in this embodiment: the clamping assembly 6 includes a mounting base 601 fixedly connected to the other side of the gantry 2. Two symmetrically arranged limiting telescopic rods 6011 are fixedly connected to the side of the mounting base 601. The ends of the two limiting telescopic rods 6011 are fixedly connected to the clamping plate 6012. A threaded sleeve 602 is also fixedly connected to the mounting base 601. A clamping bolt 6021 is threadedly connected to the threaded sleeve 602. The end of the clamping bolt 6021 near the clamping plate 6012 is rotatably connected to the side of the clamping plate 6012 through a bearing. The threaded transmission between the threaded sleeve 602 and the clamping bolt 6021 realizes the fine-tuning displacement of the clamping plate 6012 to adapt to cardboard boxes of different lengths / widths. The limiting telescopic rods 6011 ensure that the clamping plate 6012 moves smoothly and avoids skewing.

[0044] To enhance clamping stability and protect the surface of the cardboard box, in this embodiment, a clamping pad 603 is fixedly connected to the side of the clamping plate 6012 away from the clamping bolt 6021. The clamping pad 603 is made of a flexible material such as rubber or silicone to increase friction with the cardboard box and prevent slippage; at the same time, it buffers clamping pressure to avoid indentations or damage to the surface of the cardboard box.

[0045] The working principle of this utility model is as follows:

[0046] This invention achieves efficient and precise closing of cardboard boxes through a synergistic mechanism of positioning, clamping, negative pressure adsorption, and folding.

[0047] Precise positioning: Place the cardboard box to be folded on the placement shell 401, with one end abutting against the abutment plate 5011 to form a reference positioning, ensuring accurate initial position.

[0048] Adaptive clamping: Rotating the clamping bolt 6021 drives the clamping plate 6012 to move along the limiting telescopic rod 6011 through the thread transmission of the threaded sleeve 602, clamping from the other side of the carton; the clamping pad 603 buffers the pressure and enhances the friction, adapting to different sized cartons.

[0049] Stable fixation: Start the negative pressure pump 402, which adsorbs the bottom of the paper box through the negative pressure hole 4021 on the top of the housing 401, forming a uniform negative pressure field to prevent the paper box from shifting during the closing process.

[0050] Efficient folding: The electric cylinder 301 drives the folding plate 3011 to press down, the fixing part 302 presses the top of the carton, and the arc structure of the bending part 3021 simultaneously completes the side folding, reducing the risk of creases and tears.

[0051] Through the above process, this utility model achieves rapid positioning, stable fixing and efficient folding of multi-size paper boxes, significantly improving the closing accuracy, yield and equipment versatility, and is especially suitable for multi-variety, small-batch production scenarios in automated packaging production lines.
