Description

Technical Field

[0001] This utility model relates to the field of box opening technology, specifically to an auxiliary structure for opening a packaging box. Background Technology

[0002] In the packaging industry, automatic carton opening machines are widely used in automated production lines, warehousing and sorting systems, and retail displays. Their core function is to automate the opening of boxes, providing the necessary conditions for subsequent processes such as material handling, filling, and sorting. Conventional carton opening mechanisms typically utilize the coordinated operation of mechanical actuators such as linkages, gears, vacuum suction cups, and push rods to apply directional driving force to the lid and body of the box, thereby completing the opening action. Especially in the box-lifting and positioning stage, a flexible abutment rod is needed to pre-open the box body to ensure smooth insertion of the subsequent opening rod, ultimately achieving a complete opening process.

[0003] In practical applications, boxes are mostly made of paper or plastic. These materials are prone to generating static electricity during production, processing, stacking, storage, and transportation due to friction and contact separation. Due to the electrostatic adsorption effect, the lid adheres tightly to the box body, making it difficult for the elastic lever of the opening mechanism to overcome the adsorption force and open the box. This can lead to bending, tearing, or incomplete unfolding, hindering the subsequent insertion of the opening lever for opening. However, directly replacing the entire automatic box-opening machine is costly. Therefore, there is an urgent need for a packaging box opening auxiliary structure that can be added to existing automatic box-opening machines. Utility Model Content

[0004] This utility model aims to solve the technical problems existing in the prior art, and innovatively proposes a packaging box opening auxiliary structure that can be installed on existing automatic box opening machines to assist in opening the box and improve opening efficiency.

[0005] To achieve the above objectives, this utility model provides a packaging box opening auxiliary structure, which is suitable for the material rack of the opening mechanism that picks up materials from the bottom, and is installed on one side of the end of the material rack where the packaging box is placed, including a vertically arranged connecting rod and a horizontally installed abutment rod at the end of the connecting rod; The connecting rod is installed on the outside of the material rack by a clamping bolt. The connecting rod has a fixing hole for the clamping bolt to pass through, so that the connecting rod can rotate around the clamping bolt as a rotation axis. The fixing hole is located in the middle of the connecting rod, and the lengths of the connecting rod on both sides of the clamping bolt are not equal. The abutment is detachably installed on the connecting rod. Both ends of the connecting rod have mounting holes for installing the abutment. One end of the abutment extends horizontally to directly below the lid of the box when the packaging box is placed, so that when the suction cup of the external box opening mechanism picks up the packaging box and moves it downward, the abutment can hold the lid open by the abutment, thereby pulling the box body open by a gap.

[0006] In the above solution: the end of the abutment is at least located in the middle of the lid, ensuring that the extension length is as long as possible to abut the lid.

[0007] In the above scheme: the stop bar is equipped with an adjustment mechanism.

[0008] In the above solution: the adjustment mechanism includes a thread on the abutment rod, and nuts located on both sides of the connecting rod are threaded onto the abutment rod, with the nuts adjusting the position of the abutment rod and its length extending into the material rack. The threaded design allows for adjustment of the abutment rod's extension length via the nuts on both sides, resulting in a simple structure, low cost, and convenient adjustment.

[0009] In the above solution: the mounting hole is a strip-shaped hole, which facilitates the adjustment of the position of the abutment rod to ensure alignment with the center of the box cover and to ensure the abutment effect.

[0010] In summary, the beneficial effects of this utility model are as follows: the abutment is used to hold the box lid, which, while suctioning, also opens the box body by a gap, improving opening efficiency and facilitating subsequent opening operations. The connecting rod is used to rotate and adjust the height and horizontal position of the abutment to ensure alignment with the box lid. Furthermore, the different lengths on both sides of the connecting rod's rotation center allow for selection based on the packaging box's characteristics. The structure is simple and can be directly installed on existing automatic box opening machines without replacement, saving costs. Attached Figure Description

[0011] Figure 1 This is a front view of the present invention.

[0012] Figure 2 This is a cross-sectional view of the present invention. Detailed Implementation

[0013] The present invention will be further described below with reference to embodiments and accompanying drawings: like Figures 1-2 As shown, a packaging box opening auxiliary structure is provided, which is suitable for the material rack 1 of the opening mechanism that picks up materials from the bottom, and is installed on one side of the end of the material rack 1 where the packaging box is placed. It includes a vertically arranged connecting rod 2 and a horizontally installed abutment 5 at the end of the connecting rod 2.

[0014] Connecting rod 2 is mounted to the outside of material rack 1 via a retaining bolt 3. The connecting rod 2 has a fixing hole through which the retaining bolt 3 passes, allowing the connecting rod 2 to rotate around the retaining bolt 3 as its axis. The fixing hole is located in the middle of the connecting rod 2, and the lengths of the connecting rod 2 on both sides of the retaining bolt 3 are unequal. A retaining rod 5 is detachably mounted on the connecting rod 2, and both ends of the connecting rod 2 have mounting holes 4 for installing the retaining rod 5. It can be installed at either end of the connecting rod 2 according to the position of the packaging box lid, making the design reasonable.

[0015] One end of the abutment 5 extends horizontally to directly below the lid when the packaging box is placed, so that when the suction cup of the external opening mechanism picks up the packaging box and moves it downward, the abutment 5 can hold the lid open by pulling the box open a gap. The end of the abutment 5 extends to the middle of the lid but does not exceed the lid portion, ensuring that the extension length is as sufficient as possible to hold the lid open.

[0016] The abutment rod 5 has threads on its body, and nuts 6 are threadedly connected to both sides of the connecting rod 2. The nuts 6 adjust the position of the abutment rod 5 and its length extending into the material rack 1. The threaded design allows for adjustment of the abutment rod's extension length via the nuts on both sides, resulting in a simple, low-cost, and easy-to-adjust structure. Furthermore, the mounting hole 4 is a strip-shaped hole, facilitating adjustment of the abutment rod 5's position to ensure alignment with the center of the lid and guarantee a proper abutment.
