Tongue folding assembly, box sealing device, packing machine and computer readable medium

Abstract

The application provides a tongue folding assembly, a box sealing device, a packaging machine and a computer-readable medium for bending a main cover of a packaging box to form a insertion tongue, including a first base plate with a first inclined surface, a second base plate capable of bending the main cover to a first preset position in the direction of the first inclined surface, and a pressing piece capable of pressing the main cover onto the first inclined surface. When the folding tongue assembly is used to bend the insertion tongue, the bending degree of the insertion tongue can be controlled, and the bending degree can be adjusted.

         2 . The tongue folding assembly of  claim 1 , wherein the first base plate further comprises a first clamping surface, and the second base plate comprises a second clamping surface provided corresponding to the first clamping surface, and at least one first protrusion protruding towards the first base plate, to bend the main cover to the first preset position. 
     
     
         3 . The tongue folding assembly of  claim 2 , wherein the pressing piece comprises an accommodating portion provided corresponding to the first protrusion, to engage with the first protrusion. 
     
     
         4 . The tongue folding assembly of  claim 3 , wherein the first protrusion comprises a first end surface adjacent to the first base plate, and the accommodating portion comprises a first matching surface provided corresponding to the first end surface. 
     
     
         5 . The tongue folding assembly of  claim 1 , wherein the first inclined surface is provided on one side of the first base plate away from the second base plate, and the pressing piece comprises a second inclined surface provided corresponding to the first inclined surface. 
     
     
         6 . The tongue folding assembly of  claim 1 , wherein the first base plate further comprises arc-shaped first guide surfaces protruding towards the second base plate, and the second base plate further comprises arc-shaped second guide surfaces protruding towards the first base plate. 
     
     
         7 . The tongue folding assembly of  claim 1 , wherein the second base plate is further provided with a third protrusion and the third protrusion is provided at a lower part of the second base plate. 
     
     
         8 . A box sealing device comprising the tongue folding assembly of  claim 2 , further comprises a tongue inserting assembly for inserting insertion tongues into the packing box. 
     
     
         9 . A box sealing device comprising the tongue folding assembly of  claim 3 , further comprises a tongue inserting assembly for inserting insertion tongues into the packing box. 
     
     
         10 . A box sealing device comprising the tongue folding assembly of  claim 4 , further comprises a tongue inserting assembly for inserting insertion tongues into the packing box. 
     
     
         11 . The box sealing device of  claim 8 , wherein the tongue inserting assembly comprises a knocking piece, a fourth protrusion protruding from the knocking piece to limit displacement of the insertion tongue, and a third driving member for driving the knocking piece to rotate. 
     
     
         12 . The box sealing device of  claim 11 , comprising a limiting assembly provided on one side of the first base plate of the tongue folding assembly away from the pressing piece, the limiting assembly comprises a limiting piece, and a fourth driving member connected with the limiting piece to drive the limiting piece to move in a direction away from or close to the tongue inserting assembly. 
     
     
         13 . The box sealing device of  claim 11 , comprising a fifth driving member connected with the tongue folding assembly for driving the tongue folding assembly away from and close to the packing box. 
     
     
         14 . A packing machine comprising the box sealing device of  claim 8 . 
     
     
         15 . A packing machine comprising the box sealing device of  claim 11 . 
     
     
         16 . A packing machine comprising the box sealing device of  claim 12 . 
     
     
         17 . A computer readable medium, capable of connecting with the tongue folding assembly of  claim 2 , having stored therein preset program that, when executed, causes to carry out the following steps: clamping, by a first base plate and a second base plate, to bend a main cover to a first preset position in a direction close to a first inclined surface, and pressing, by a pressing piece, the main cover onto a first inclined surface to form a insertion tongue. 
     
     
         18 . A method for bending and inserting insertion tongues of a packing box, comprising the following steps:
 driving, by a fifth driving member, a tongue folding assembly to move to a preset position;   driving, by a first driving member, a first base plate and a second base plate to clamp to bend a main cover to a first preset position;   driving, by a second driving member, a pressing piece to press the main cover onto a first inclined surface;   driving, by the second driving member, the pressing piece to return, and driving, by the first driving member, the first base plate and the second base plate to return;   driving, by the fifth driving member, the tongue folding assembly to return;   driving, by a sixth driving member, a tongue inserting assembly to another preset position;   driving, by a third driving member, a knocking piece to insert the insertion tongue into a packing box; and   driving, by the third driving member, the knocking piece to return, and driving, by the sixth driving member, the tongue inserting assembly to return.
