Description

Technical Field

[0001] This utility model relates to the field of carton opening machine technology, and in particular to a carton opening machine for egg packaging cartons. Background Technology

[0002] Currently, cardboard boxes are commonly used for packaging egg products. Since the original cardboard boxes are in a folded, flat state, it is necessary to open the cardboard boxes before placing the products inside.

[0003] A search revealed a carton opening machine under publication number CN220743510U, comprising: a feeding ramp with a limiting groove and a sliding groove at its inner diameter, the sliding groove being connected to a sliding plate; a storage platform located at the lower side of the feeding ramp, equipped with an electric telescopic rod and a slide rail with an adjusting rod inside, the connection between the storage platform and the adjusting rod being fitted with a positioning plate; and a suction forming mechanism located on the side of the storage platform, with a conveyor belt positioned on its side. This invention allows adjustment of the height of the telescopic push plate on the sliding plate through sliding between the sliding plate and the fixed track groove, thus adapting to different sizes of carton boards. The telescopic push plate can also adapt to carton boards of different widths, preventing tilting of the carton board's trajectory due to incomplete contact between the carton board and the telescopic push plate.

[0004] Although the above solution can adjust the height of the telescopic push plate on the slider by sliding between the slider and the fixed track groove, thus adapting to different sizes of cardboard boxes, and the telescopic push plate can also adapt to cardboard boxes of different widths, the bottom of the cardboard box is prone to deviation during the sealing process, which may result in the bottom of the cardboard box not being sealed. Therefore, we propose a carton opening machine for egg packaging cartons. Utility Model Content

[0005] The main purpose of this utility model is to provide a carton opening machine for egg packaging cartons. By setting up an opening unit and a transmission unit, it solves the problem that the bottom of the carton is prone to deviating during the sealing process, which can lead to the bottom of the carton not being sealed.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A carton opener for egg packaging cartons includes a main unit, a clamping unit disposed on the side of the main unit, an opening unit disposed inside the main unit, and a transmission unit disposed at the end of the main unit.

[0008] The unpacking unit includes a rectangular groove formed on the side wall of the main unit, an L-shaped connecting seat installed on the side wall of the main unit, a hydraulic telescopic cylinder installed on the inner bottom wall of the L-shaped connecting seat and extending through the rectangular groove into the interior of the main unit, an adsorption component set at the telescopic end of the hydraulic telescopic cylinder, and a pushing component set inside the main unit.

[0009] The transmission unit includes a fixed base disposed at the output end of the main unit, a conveyor belt movably disposed inside the fixed base, a third drive motor installed at the input end of the conveyor belt, a correction component disposed above the fixed base, and a bottom seal disposed inside the main unit and located below the rectangular groove.

[0010] Preferably, the main body unit includes a working box, a support leg installed at the bottom of the working box, a feed port opened on the side wall of the working box, and an inclined feed plate installed on the side wall of the working box and communicating with the feed port.

[0011] Preferably, the clamping unit includes a fixed groove formed in the top wall of the feed inlet, a threaded shaft movably disposed inside the fixed groove, a movable part installed on the circumferential side of the threaded shaft, a first limiting plate installed at the bottom of the movable part, a first drive motor installed at the input end of the threaded shaft, and a top limiting part disposed above the work box.

[0012] Preferably, the top limiting component includes an L-shaped connecting plate installed on the top of the work box, an electric telescopic rod installed at the bottom of the L-shaped connecting plate, and a second limiting plate installed at the telescopic end of the electric telescopic rod.

[0013] Preferably, the adsorption component includes an adsorption box installed at the extension end of the hydraulic telescopic cylinder, a suction cup installed at the output end of the adsorption box, and a suction pump installed at the input end of the adsorption box.

[0014] Preferably, the pusher includes a movable groove formed in the inner side wall of the work box, a threaded rod movably disposed inside the movable groove, an L-shaped movable seat mounted on the periphery of the threaded rod, a second drive motor mounted on the input end of the threaded rod, and a pusher rod mounted on the bottom of the L-shaped movable seat.

[0015] Preferably, the correction component includes a fixed plate installed on the top of the work box, a connecting spring installed on the inner side wall of the fixed plate, and an inclined plate installed on the end of the connecting spring. There are two sets of correction components, and the two sets of correction components are symmetrically arranged about the bisecting plane of the conveyor belt.

[0016] Preferably, the bottom seal includes a rotating shaft movably disposed inside the working box, a sealing support plate installed on the side wall of the rotating shaft, and a fourth drive motor installed at the input end of the rotating shaft. There are two sets of bottom seals, and the two sets of bottom seals are symmetrically arranged about the bisecting plane of the working box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this invention, through the set opening unit and transmission unit, when it is necessary to open the carton board, the carton board is placed at the inlet by the inclined feeding plate. The first drive motor drives the threaded shaft to rotate, and the moving part drives the first limiting plate to move along the threaded shaft until the first limiting plate is in contact with the side of the carton board and stops. Then, the extension end of the electric telescopic rod extends, causing the second limiting plate to move down until it is in contact with the top of the carton board and stops. Then, the extension end of the hydraulic telescopic cylinder extends, causing the suction member to move towards the carton board until the suction cup is in contact with the carton board and stops. At this time, the suction pump works to suction the carton board onto the suction cup. Then, the hydraulic telescopic cylinder retracts, causing the cardboard box to open into a box shape, thus enabling convenient opening of the cardboard box. When it is necessary to seal the bottom of the cardboard box, when the cardboard box is opened, the second drive motor drives the threaded rod to rotate, and the L-shaped moving seat drives the pusher rod to move along the threaded rod. The pusher rod pushes the box onto the conveyor belt. During the conveying process, the correction component can gather the packaging boxes to the middle of the conveyor belt for conveying. During this process, the fourth drive motor drives the rotating shaft to rotate, causing the sealing plate to push the bottom plate of the cardboard box to seal the bottom of the box, thus achieving convenient sealing of the bottom of the cardboard box and improving the opening effect.
