Box sealing device, packing machine and computer-readable medium

Abstract

The present application discloses a box sealing device, a packaging machine and a computer-readable medium. The box sealing device can be used for sealing a packaging box; the packaging box comprises a main plate and a main cover, and further has a pressing piece, and a bending piece connected to the pressing piece and bending towards the main plate to a preset angle. The box sealing device does not need a plurality of folding plates cooperating, and the structure is simple.

1 . A box sealing device for sealing a packing box which comprising a main plate and a main cover, comprising a pressing piece, a bending piece connected with the pressing piece and bent toward the main plate to a preset angle, and a first driving assembly connected with the pressing piece and/or the bending piece to drive the bending piece to move close to the main plate, the pressing piece is moving in cooperation with the bending piece;
 further comprising a grasping piece capable of grasping the main plate, and a second driving assembly capable of driving the grasping piece to drive the main plate away from and/or close to the main cover;   a first limiting piece capable of limiting a displacement of the main plate and is disposed at one side of the grasping piece; and   a third driving member connected with the first limiting piece to drive the first limiting piece to move.   
     
     
         2 . The box sealing device of  claim 1 , further comprising a second limiting piece disposed on one side of the grasping piece away from the first limiting piece, and a fourth driving member connected with the second limiting piece to drive the second limiting piece to move. 
     
     
         3 . The box sealing device of  claim 2 , wherein the second limiting piece comprises a second limiting piece body and two second protrusions protruding from the second limiting piece body, the two second protrusions are arranged in a spaced manner. 
     
     
         4 . The box sealing device of  claim 1 , wherein the first driving assembly comprises a first driving member and a first connecting piece disposed between the first driving member and the pressing piece. 
     
     
         5 . The box sealing device of  claim 1 , wherein the pressing piece comprises a pressing piece body and two first protrusions arranged on the pressing piece body in a spaced manner. 
     
     
         6 . The box sealing device of  claim 1 , wherein the second driving assembly comprises a second connecting piece and a protruding piece protruding from the second connecting piece, the grasping piece is disposed on the protruding piece. 
     
     
         7 . The box sealing device of  claim 1 , further comprising a pushing piece disposed on one side of the main cover away from the main plate, and a third driving assembly capable of driving the pushing piece to move to the main cover. 
     
     
         8 . A packing machine, comprising the box sealing device of  claim 1 . 
     
     
         9 . A packing machine, comprising the box sealing device of  claim 2 . 
     
     
         10 . A packing machine, comprising the box sealing device of  claim 3 . 
     
     
         11 . A packing machine, comprising the box sealing device of  claim 4 . 
     
     
         12 . A packing machine, comprising the box sealing device of  claim 5 . 
     
     
         13 . A packing machine, comprising the box sealing device of  claim 6 . 
     
     
         14 . A packing machine, comprising the box sealing device of  claim 7 . 
     
     
         15 . A non-transient computer-readable medium, which can be connected with the box sealing device of  claim 1 , having stored a preset program that, when executed, cause to carry out the following steps: driving, by a first driving assembly, a pressing piece to move, to allow the pressing piece to press a main cover on a main plate, and a bending piece to move to one side of the main plate away from the main cover, so as to cooperate with the main plate to bend the main cover to form an insertion tongue. 
     
     
         16 . A computer-readable medium, which can be connected with the box sealing device of  claim 1 , having stored a preset program that, when executed, cause to carry out the following steps: driving, by a third driving part, a first limiting piece to move so as to limit a displacement of a portion of a main plate of a packing box; and driving, by a second driving member, a grasping piece to grasp the main plate of the packing box and drive the main plate to move away from the packing box.
