Description

Differential speed sealing mechanism of unpacking machine

technical field

The present invention relates to a differential speed sealing mechanism of a carton opening machine, in particular to an optimized carton tape sealing effect, which can increase the efficiency of carton folding cover and tape sealing. The innovative designer of the differential sealing mechanism of the unpacking machine that implements more practical features in use.

Background technique

By the way, all kinds of products on the market are generally packaged in cartons when they are manufactured and leave the factory. On the one hand, it can protect the integrity of the product and not be easily damaged by external forces. On the other hand, it can facilitate the transportation of the product. In order to save the space occupied by the cartons before this kind of cartons are used, all the cartons are stacked in an unexpanded state; therefore, in the early days of using cartons for various Before the product is packaged and sealed, the carton needs to be unfolded manually, and after the bottom of the carton is pasted and sealed, the product is loaded into the carton, and finally the top of the carton is sealed and fixed to complete the packing operation. However, also because the above-mentioned method of manually carrying out the carton unfolding operation needs to consume more human resources and increase its cost expenditure, so that with the rapid development of the automation industry, various automatic carton unpacking machines have begun to come out.

Among them, please refer to No. M421921 "Composite Interlocking Folding Mechanism for Unpacking Machine" announced on February 1, 2012, which mainly has a power shaft driven by a power source in the machine, and the power shaft The upper cover is fitted with a side cover cam and a lower cover cam; among them, a side cover unit is provided corresponding to the side cover cam, and the side cover unit is provided with a side cover drive arm to drive the side cover The middle position of the arm is pivotally set on the machine table, and the first end of the side folding cover driving arm is provided with a supporting part corresponding to the side folding cover cam, and the second end is connected with a reset elastic device fixed with the machine table and a pivoting device Folding right cover connecting rod, the folding right cover connecting rod is connected with the first end of the linkage, the linkage is pivotally equipped with folding right cover push rod at the middle position, and is connected with the second end of the linkage with a folding The connecting rod of the left cover, the connecting rod of the folding left cover is pivotally equipped with a steering paddle, which is connected and combined with the push plate of the folding left cover; The unit is provided with a lower folding cover driving arm, the first end of the lower folding cover driving arm is pivotally combined with the machine table, and the middle section of the lower folding cover driving arm is provided with a propping part corresponding to the lower folding cover cam, and the lower folding cover cam The second end is then connected with a resetting elastic device fixed with the machine table and is pivotally provided with a fold-down cover connecting rod, which is connected with a fold-down cover push plate.

However, although the above-mentioned "composite linkage folding mechanism of the unpacking machine" can achieve the expected effect of automatically opening and folding the unexpanded carton, it is also found in its actual implementation that the unpacking machine was The rear section is equipped with a fixed tape unit, so that after the carton is opened and folded, the carton will be sent to the tape unit for tape sealing. In order to improve the sealing efficiency of the cover and the tape, the operating speed of the power source is generally increased to speed up the transmission speed of the carton. When the carton is delivered to the tape sticking unit, the carton will be dented and deformed due to the excessive impact force with the tape sticking unit, so that there is still room for improvement in its overall structural design.
