[0002] When packaging wine bottles, in order to improve their aesthetics and stability during transportation, a cylindrical packaging box is generally placed on the outside of the wine bottles. In order not to affect the viewing of the wine bottles inside, it is necessary to open a hole on the side of the packaging box to form an observation window so that the wine bottles inside can be seen, and then a layer of transparent plastic sealing material is sealed inside the observation window.

[0003] The location, shape, and size of the holes are usually determined by the characteristics of the product and the design requirements of the packaging box. The number of holes should not be too large to avoid affecting the strength of the packaging box. In the existing technology, holes are mostly made manually on the side of the packaging box, which is not only inefficient but also difficult to control the location, shape, and size of the holes, resulting in poor product quality.

DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Example 1

[0024] A device for opening a hole in a cylindrical packaging box comprises a processing platform 5 and a support frame 1 arranged above the processing platform 5. The processing platform 5 is provided with an adjustment mechanism 4 for rotating the packaging box. The adjustment mechanism 4 includes a transmission roller 41, and the packaging box is sleeved on the transmission roller 41; a hydraulic lifting column 2 is installed on the support frame 1, and the bottom end of the hydraulic lifting column 2 is connected to an electric cutting knife 3; the electric cutting knife 3 is arranged corresponding to the roller.

[0025] When the present invention is in use, the packaging box is placed on the transmission roller 41. It should be noted that one end of the transmission roller 41 is connected to a driving motor to drive the transmission roller 41 to rotate, and then the hydraulic lifting column 2 is started to drive the electric cutting knife 3 to descend, and then the electric cutting knife 3 is started (the electric cutting knife 3 is connected to the external central control system and controlled by the central control system) to cut the outer side of the packaging box. During the cutting process, the transmission roller 41 drives the packaging box to rotate. In addition, it should be noted that the hydraulic lifting column 2 is connected to the external central control system, which can control the lifting and lowering of the hydraulic lifting column 2, and then control the size of the hole opened on the side of the packaging box.

[0026] In this embodiment, the adjustment mechanism 4 also includes a support base 42 for supporting the transmission roller 41. The support base 42 is movably connected to the processing platform 5 and can move along the processing platform 5. On the one hand, due to the different sizes of the packaging boxes, the position of the packaging box on the transmission roller 41 may be different, so the correspondence with the position of the electric cutting knife 3 on the top may be poor; on the other hand, the positions of the cutting holes required for different packaging boxes are also different, that is, the position correspondence between the packaging box and the electric cutting knife 3 is different. In this way, the position of the transmission roller can be adjusted according to needs, and then the corresponding position of the packaging box and the electric cutting knife 3 can be adjusted to cut at the required position on the outer peripheral surface of the packaging box.

[0027] In this embodiment, a slide rail 51 is provided on the processing platform 5, and a slider 43 that can move along the slide rail 51 is provided at the bottom of the support base 42; preferably, a plurality of limiting holes can be provided on the slider 43 and the slide rail 51, so that it is convenient to pass the limiting studs through the limiting holes to limit the connection between the slider 43 and the slide rail 51, thereby maintaining adjustability and stability in use.

[0028] In this embodiment, the front end of the transmission roller 41 is movably connected to a positioning cylinder 6, and the outer diameter of the positioning cylinder 6 gradually increases from the end away from the transmission roller 41 to the end close to the transmission roller 41; in this way, the opening of the packaging box is sleeved on the positioning cylinder 6, which can be applicable to packaging boxes of different calibers and has a wider range of applications; and at least two groups of positioning parts for positioning the opening of the packaging box are provided on the outer circumferential surface of the positioning cylinder 6, and the two groups of positioning parts are symmetrically arranged along the central axis of the positioning cylinder 6, and the opening of the packaging box is limited by the positioning parts, so that the positioning of the packaging box can be made more secure, thereby ensuring the stability of the rotation process of the packaging box.

[0029] In this embodiment, each group of the positioning members includes a plurality of positioning buckles 61, and the positioning buckles 61 are evenly arranged along the outer side surface of the positioning cylinder 6; the positioning buckles 61 are arranged at an angle, and the free ends of the positioning buckles 61 face the transmission roller 41; and there is a gap between two adjacent positioning buckles 61; in this way, the open end of the packaging box is arranged in the gap between the two adjacent positioning buckles 61, so that the packaging box can be limited and the stability of the packaging box can be ensured.

[0030] In this embodiment, the positioning tube 6 and the positioning buckle 61 are made of soft materials, which can avoid damage to the packaging box.

[0031] In this embodiment, a pair of limiting rods 63 are provided at one end of the positioning cylinder 6 facing the transmission roller 41, and the pair of limiting rods 63 respectively penetrate the transmission roller 41 and extend to the outside of the transmission roller 41; the interior of the positioning cylinder 6 is a hollow cavity, and a plurality of limiting springs 62 are provided inside the positioning cylinder 6, and the two ends of the limiting springs 62 respectively abut against the inner walls on the opposite sides of the positioning cylinder 6; in this way, when the packaging box needs to be removed from the positioning cylinder 6, the pair of limiting rods 63 can be pinched and force can be applied toward each other, that is, the pair of limiting rods 63 can be clamped, thereby compressing the limiting springs 62 inside the positioning cylinder 6, tightening the positioning cylinder 6 inward, that is, reducing the outer diameter of the positioning cylinder 6, and then the open part of the packaging box is freed from the constraint of the positioning buckle 61 and directly removed from the positioning cylinder 6.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
