Description

Technical Field

[0001] This utility model belongs to the field of packaging carton processing technology, and in particular relates to a packaging carton creasing device. Background Technology

[0002] Packaging carton processing refers to the process of manufacturing cartons from paper or cardboard into packaging boxes for various items through a series of processes. This process typically includes multiple steps such as raw material preparation, cutting, printing, creasing, folding, and gluing. Raw materials, such as corrugated cardboard, are cut to specific sizes, then printed with brand logos, product information, and other graphics and text. Subsequently, the cardboard is creasing to allow it to be folded smoothly into shape. Finally, the cardboard is folded and glued to form cartons.

[0003] Chinese patent CN222628762U discloses a creasing device for processing packaging cartons. The device includes a base box, a processing box fixedly connected to the top of the base box, a dust removal component on the left side of the top of the processing box, the dust removal component including a dust removal chamber, a dust removal pipe connected to the bottom of the inner cavity of the dust removal chamber, a dust removal head connected to the bottom of the dust removal pipe, and a vacuum cleaner installed at the top of the inner cavity of the dust removal chamber. This invention, by setting up a dust removal component, can adsorb surface dust from cartons entering the processing box, avoiding the problem of poor creasing quality caused by dust and fine particles on the top of the cartons during creasing operations. The creasing component allows for adjustment of the creasing spacing, enabling creasing of cartons of different sizes and improving creasing efficiency. It also allows for adjustment of the creasing angle, further improving the creasing effect.

[0004] However, in the above-mentioned scheme, when using the creasing device for processing packaging cartons, there are two main problems. First, the conveyor belt's support structure is relatively simple, relying solely on a fixed plate for support. This makes it difficult to ensure the conveyor belt remains taut at all times. This can lead to slackness during long-term operation or under heavy loads, affecting the uniformity of the creasing depth and causing differences in creasing depth at different locations, thus impacting creasing quality. Second, although dust removal and creasing components are included, there is a lack of stable fixing measures for the cartons during conveyor belt transport. This fails to effectively prevent the cartons from shifting due to the force of the creasing blade or other external forces during transport, potentially leading to inaccurate creasing positions and affecting the final processing effect of the cartons. Therefore, designing a packaging carton creasing device is essential. Utility Model Content

[0005] This utility model provides a packaging carton creasing device, which aims to solve the problems of inconsistent creasing depth caused by the easy loosening of the conveyor belt and inaccurate creasing caused by the easy displacement of the carton in the current device.

[0007] Preferably, the cardboard conveying assembly includes: a mounting frame fixedly installed on the top of the base, a front roller shaft movably installed inside the mounting frame, a motor fixedly installed on one side of the mounting frame, a drive shaft of the motor fixedly connected to one end of the front roller shaft, a rear roller shaft movably installed at the other end of the mounting frame, and a conveyor belt body sleeved on the outer surfaces of the front roller shaft and the rear roller shaft.

[0008] Preferably, the conveyor belt tensioning assembly includes: a bottom frame fixedly installed at the bottom of the mounting frame, an installation limiting groove provided on the bottom frame and the mounting frame, an electric telescopic rod fixedly installed inside the installation limiting groove, and a lower pressure roller shaft fixedly installed on the top of the electric telescopic rod.

[0009] Preferably, the cardboard dust removal assembly includes: an indentation frame fixedly installed on the top of the mounting frame, a dust suction head fixedly installed inside the indentation frame, a collection box fixedly installed on the top of the indentation frame, a fan fixedly installed on the top of the collection box, and the dust suction head communicating with the collection box.

[0010] Preferably, the cardboard fixing assembly includes: a second motor fixedly installed on one side of the creasing frame, a U-shaped rod movably installed inside the creasing frame, and a fixed roller shaft movably sleeved on the outer surface of the U-shaped rod.

[0011] Preferably, there are two sets of fixed rollers, and the two sets of fixed rollers are equidistantly arranged on the outer surface of the U-shaped rod.

[0012] Preferably, the cardboard creasing assembly includes: a hydraulic lifting rod fixedly installed on the top of the inner surface of the creasing frame; a limiting frame fixedly installed at the bottom of the hydraulic lifting rod; a dual-axis motor fixedly installed inside the limiting frame; a lead screw fixedly installed on the drive shaft of the dual-axis motor; a moving block movably sleeved on the outer surface of the lead screw; and a creasing head fixedly installed at the bottom of the moving block.

[0013] Preferably, the hydraulic lifting rod, lead screw, moving block, and indentation head are provided in two sets, and the two sets of hydraulic lifting rod, lead screw, moving block, and indentation head are symmetrically arranged on the limiting frame.

[0014] Compared with related technologies, the packaging carton creasing device provided by this utility model has the following beneficial effects: In operation, firstly, start motor one to rotate the front roller shaft, causing the conveyor belt to run. Place the carton to be processed onto the conveyor belt for transport. At this time, the electric telescopic rod in the conveyor belt tensioning assembly operates, pushing the lower pressure roller shaft to apply pressure to the conveyor belt, ensuring it remains taut and preventing inconsistent creasing depth due to slack. During transport, the carton passes through the cardboard dust removal assembly, where a fan starts, sucking dust from the carton surface into a collection box, ensuring cleanliness and improving creasing quality. Next, the carton reaches the cardboard fixing assembly, where motor two drives the U-shaped rod to rotate, clamping the two sets of fixed rollers between the carton's sides to prevent shifting during creasing. Then, the cardboard creasing assembly operates; the hydraulic lifting rod lowers the limit frame, and the dual-axis motor drives the lead screw to rotate, causing the moving block to drive the creasing heads to creasing the carton. Both sets of creasing heads can creasing simultaneously, improving work efficiency. Through the coordinated operation of the above components, the device effectively solves the problems of conveyor belt slack and carton misalignment, ensures the uniformity of creasing depth and the accuracy of creasing position, and improves the overall quality of carton processing.
