Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carton processing equipment, and particularly relates to a high-compatibility automatic carton folding machine. BACKGROUND

[0002] In the process of automation upgrading in the packaging industry, the multi-specification adaptability, process linkage efficiency and intelligent control capability of the automatic carton folding machine have become the core factors restricting the production capacity and product yield of the production line. In the prior art, although related equipment attempts to solve the technical pain points in a single dimension, it has not yet formed an intelligent solution covering the whole process of "conveying-measuring-folding-cleaning". The specific defects can be further analyzed in combination with comparative document 1: CN202420226453.5, a conveying mechanism of an automatic carton folding machine, and comparative document 2 (CN202510479004.0, a paper box folding equipment for paper box processing): The core design of the automatic carton folding machine conveying mechanism disclosed in comparative document 1 is to move the sliding frame by a forward and reverse toothed rod to adapt to different widths of the carton. However, this scheme has three major defects: first, the dimension adaptation is single and manual, and only the sliding frame spacing can be adjusted by manually rotating the hand wheel to adapt to the width of the carton. For changes in the length and height of the carton, the chain wheel conveying part needs to be completely disassembled and re-calibrated and installed, and the single adjustment time is more than 30 minutes, which completely cannot meet the rapid changeover requirements of "multi-variety and small batch" production; second, the adjustment precision and stability are poor, the transmission shaft adopts a "cylinder + prism" structure, but there is no positioning scale and locking mechanism between the sliding sleeve and the prism. When manually adjusting, the sliding sleeve is easily offset due to uneven force, and the paper box conveying path deviation often exceeds 0.5 mm, directly causing the carton folding yield to be less than 95%; third, the process linkage is missing, and the conveying mechanism has no any electrical linkage with the subsequent processes such as folding and glue spraying. The operator needs to continuously observe the position of the carton and manually adjust the conveying speed. When the carton specification is switched, the conveying speed and folding rhythm are easily out of sync, causing frequent paper jam failures, with an average of 2-3 times of shutdown per hour, which seriously damages the production continuity. In addition, this scheme does not involve any safety protection and visualization design. The equipment enclosure is a fully enclosed sheet metal structure, and fault troubleshooting needs to completely disassemble the enclosure, further prolonging the maintenance time, which is completely out of touch with the "efficient maintenance" requirements of industrial production.

[0003] The paper box folding equipment disclosed by Comparative Document 2 integrates the functions of measuring, cutting, folding and cleaning, but still has significant technical shortcomings: first, the change efficiency is low and depends on manual operation. Although the measuring component is arranged to obtain the size of the paper box, the cutting knife position adjustment and the folding plate stroke setting need to be manually input one by one, without any formula storage function. When the production line switches more than three specifications of paper boxes, the parameter setting time accumulates more than one hour, and the cutting deviation is easily caused by manual input error, and the first piece qualified rate is only 90%; second, the 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 thickness of the paperboard fluctuates by ±0.2mm, the conveying speed is not adjusted synchronously, resulting in uneven contact pressure between the measuring plate and the paperboard, and the measurement error is expanded to 0.3mm, which further causes the cutting precision deviation; third, the cleaning component lacks self-adaptation. The cleaning component relies on the fixed height chain wheel-tooth plate transmission to push the waste out. When the thickness of the waste increases from 0.5mm to 2mm, the pushing block cannot completely match the surface of the waste, and the cleaning residual rate is more than 10%, which needs to arrange a special person for secondary cleaning, which increases the labor cost; fourth, there is no parameter self-optimization capability. The key processing parameters such as glue spraying amount and pressure maintaining time need to be preset according to the experience of the operator, and cannot be dynamically adjusted according to the water absorption and hardness of the paperboard material (such as cardboard and corrugated paper), resulting in excessive glue overflow (glue overflow rate 6%) for thin paperboard and poor adhesion (glue opening rate 8%) for thick paperboard due to insufficient pressure maintaining, and the finished product failure rate is as high as 14%, which cannot meet the "high yield" requirement of the food and pharmaceutical industries.

[0004] From the comparison of Comparative Documents 1 and 2, it can be seen that the existing automatic box folding machines generally have three common problems: first, the multi-dimensional compatibility is missing. They are only adjusted in a single dimension (width or length), and the "length x width x height" three-dimensional automatic adaptation has not been achieved, and the adjustment mode is mainly manual, the change efficiency is low, and it cannot meet the market demand of "multi-specification, fast iteration"; second, the whole process linkage is blank. The measurement, conveying, folding and cleaning processes are mostly independent control units, without integrated control system, and the parameters cannot be dynamically adjusted according to the real-time working condition, which is easy to cause the process to be out of sync and cause faults. SUMMARY

[0005] The present application aims to overcome at least one of the above-mentioned problems of the prior art, and provides a high-compatibility automatic box folding machine to achieve flexible adaptation according to the size of the paper sheet, improve the applicability of the machine, reduce manual operation and improve the yield.
