Description

Technical Field

[0001] This utility model relates to the field of paper box processing equipment technology, specifically to a highly compatible automatic folding box machine. Background Technology

[0002] In the process of automation upgrading in the packaging industry, the multi-specification adaptability, process linkage efficiency, and intelligent control capabilities of automatic box folding machines have become core factors restricting production line capacity and product yield. While some existing technologies attempt to address single-dimensional technical pain points, a comprehensive intelligent solution covering the entire "conveyance-measurement-folding-cleaning" process has yet to be formed. Specific deficiencies can be further analyzed in conjunction with comparative document 1: CN202420226453.5, "A Conveying Mechanism for an Automatic Box Folding Machine," and comparative document 2 (CN202510479004.0, "A Carton Folding Device for Carton Processing"). The automatic folding box conveyor mechanism disclosed in document 1 is designed to move the slide by using positive and negative threaded rods to adapt to cartons of different widths. However, this solution has three major drawbacks: First, the dimensional adaptation is limited and manual, requiring manual adjustment of the carriage spacing by rotating a handwheel to match the carton width. For changes in carton length or height, the sprocket conveyor components must be completely disassembled and recalibrated, with each adjustment taking more than 30 minutes, which is completely unacceptable for the rapid changeover requirements of "multiple varieties and small batches" production. Second, the adjustment accuracy and stability are poor. The drive shaft adopts a "cylindrical + prism" structure, but there are no positioning scales or locking mechanisms between the sliding sleeve and the prism. During manual adjustment, uneven force can easily cause the sliding sleeve to shift, resulting in a carton conveying path deviation that often exceeds 0.5mm, directly causing the folding yield rate to be below 95%. Third, the process linkage is lacking. The conveying mechanism has no electrical linkage with subsequent processes such as folding and gluing, requiring operators to continuously observe the carton position and manually adjust the conveying speed. When carton specifications are changed, the conveying speed and folding rhythm are easily out of sync, leading to frequent paper jams and an average of 2-3 downtimes per hour, severely disrupting production continuity. Furthermore, the solution lacks any safety protection or visualization design. The equipment enclosure is a fully enclosed sheet metal structure, requiring complete disassembly of the enclosure for troubleshooting, which further extends maintenance time and is completely out of step with the "efficient maintenance" requirements of industrial production.

[0003] The carton folding equipment disclosed in Comparative Document 2, while integrating measurement, cutting, folding, and cleaning functions, still has significant technical shortcomings: First, changeover efficiency is low and reliant on manual labor. Although a measuring component is set up to obtain carton dimensions, the adjustment of the cutting blade position and the setting of the folding plate stroke require manual input of parameters one by one. There is no formula storage function. When the production line switches to more than three specifications of cartons, the parameter setting time accumulates to more than one hour, and manual input errors easily lead to cutting deviations, resulting in a first-piece pass rate of only 90%. Second, process linkage is poor. The measuring component and the conveying component operate independently, and the measurement data cannot be fed back to the conveying system in real time. When the cardboard thickness fluctuates by ±0.2mm, the conveying speed is not adjusted synchronously, resulting in uneven contact pressure between the measuring plate and the cardboard, and the measurement error expands to 0.3mm. The thickness of the waste material increases from 0.5mm to 2mm, leading to subsequent cutting accuracy deviations. Thirdly, the cleaning component lacks self-adaptability. It relies on a fixed-height sprocket-tooth plate drive to push the waste material out. When the waste material thickness increases from 0.5mm to 2mm, the pushing block cannot fully adhere to the waste surface, resulting in a cleaning residue rate exceeding 10%. This necessitates a second cleaning by a dedicated person, increasing labor costs. Fourthly, it lacks parameter self-optimization capabilities. Key processing parameters such as glue application amount and holding time must be preset based on operator experience. They cannot be dynamically adjusted according to the absorbency and hardness of the cardboard material (such as cardboard or corrugated paper). This results in excessive glue overflow on thin cardboard (6% overflow rate) and insufficient holding pressure on thick cardboard (8% delamination rate), leading to a finished product defect rate as high as 14%, far from meeting the "high yield" requirements of the food and pharmaceutical industries.

[0004] A comprehensive comparison of documents 1 and 2 reveals three common problems with existing automatic box folding machines: First, they lack multi-dimensional compatibility, adjusting only a single dimension (width or length) and failing to achieve automatic adaptation across the three dimensions of "length × width × height." Furthermore, the adjustment is primarily manual, resulting in low changeover efficiency and an inability to meet the market's demand for "multiple specifications and rapid iterations." Second, they lack full-process linkage, with measurement, conveying, folding, and cleaning processes mostly operating as independent control units without an integrated control system. This makes it impossible to dynamically adjust parameters based on real-time operating conditions, leading to malfunctions caused by process disconnections. Utility Model Content

[0005] The present invention aims to overcome at least one of the defects of the prior art and provide a highly compatible automatic folding box machine to achieve flexible adaptation according to the size of the paper, improve the applicability of the machine, reduce labor, and increase productivity.

[0006] This utility model provides a highly compatible automatic box folding machine, comprising: The frame is used for load-bearing and support; The feeding assembly, located at the top of the frame, includes a feeding base, a feeding conveying mechanism, and an adjusting mechanism. The feeding conveying mechanism, mounted on the base, can be composed of a conveyor belt and a drive device, and is responsible for material conveying. The adjusting mechanism includes a first feeding drive assembly, a first side baffle assembly, a second feeding drive assembly, and a second side baffle assembly. The two side baffle assemblies are respectively located on both sides of the feeding conveying mechanism, and the two feeding drive assemblies are located below the feeding base. The width positioning of the material in the feeding direction is achieved by driving the side baffle assemblies to move horizontally. This structure, by placing the feeding drive assembly below the feeding base, avoids interference with the upper feeding space and saves overall equipment space. The independent side baffle assemblies on both sides, in conjunction with the feeding drive assemblies, can flexibly adjust the spacing to adapt to materials of different widths, solving the problem of poor adaptability of traditional feeding assemblies and improving the versatility of the equipment.

[0007] The components include: a front panel assembly for receiving paper sheets fed by the feeding assembly; a picking assembly for picking up paper sheets fed by the front panel assembly; a transfer assembly for transferring paper sheets fed by the picking assembly; a first folding assembly for folding both sides of the paper sheet; a second folding assembly for folding the side ears and back cover of the paper sheet; an adhesive dispensing assembly for spraying adhesive onto the paper sheet folded by the second folding assembly; a third folding assembly for folding the paper sheet onto the side ears and closing the cover to form a cardboard box; and a pressure holding assembly for applying stable pressure to the cardboard box to ensure that the hot melt adhesive adheres tightly to the cardboard, thus ensuring that the cardboard box is firmly bonded and retains its shape.

[0008] A chain conveyor assembly, located in the middle of the frame, is used for dynamic transport of paper sheets during folding, gluing, and pressure holding processes. It includes a first track assembly, a second track assembly, and a third track assembly arranged parallel to each other in the material transport direction; it also includes a first material conveying drive assembly and a second material conveying drive assembly fixed to one side of the first track assembly. The first material conveying drive assembly is used to achieve horizontal material transport and specifically includes a first motor unit, a first screw assembly, a first sprocket, a second sprocket, a third sprocket, a fourth sprocket, a first chain, and a second chain. The first and second sprockets are installed inside the first track assembly, and the third and fourth sprockets are installed inside the second track assembly. One end of the first chain meshes with the first sprocket, and the other end meshes with the second sprocket. One end of the second chain meshes with the third sprocket, and the other end meshes with the fourth sprocket. One end of the first screw assembly passes through the first sprocket and the first track assembly sequentially and connects to the first motor unit; the middle section passes through the third sprocket and the second track assembly; and the other end passes through the third track assembly.

[0009] By combining the parallel layout of the multi-track components with the synergistic effect of the material conveying drive components, stable horizontal material transport can be achieved. The track spacing can also be flexibly adjusted through the second material conveying drive components, adapting to materials of different widths without manual adjustment. This significantly improves the equipment's compatibility with materials of various specifications and reduces downtime during production changes. At the same time, the cooperation of the sprockets, chains, and lead screws ensures precise positioning of materials during transport, providing a fundamental guarantee for the stability of the subsequent box folding process.

[0010] This invention achieves full automation of the paper box production process from material feeding to forming through integrated and modular design. The chain conveyor assembly adopts a multi-track and adjustable drive structure, significantly improving the equipment's adaptability to paper sheets of different sizes and enhancing production flexibility and efficiency. The first folding assembly, second folding assembly, glue dispensing assembly, third folding assembly, and pressure holding assembly are sequentially arranged on both sides of the chain conveyor assembly according to the process sequence.
