[0028] A lifting mechanism is provided on the top of the base plate 1;

[0029] Among them, the lifting mechanism includes a transmission motor 5, the bottom of the transmission motor 5 is fixedly connected to the top of the base plate 1, the other end of the output shaft of the transmission motor 5 is fixedly sleeved with a transmission shaft 6, the outer surface of the transmission shaft 6 is fixedly sleeved with a driving round wheel 7, the driving round wheel 7 is connected to the driven round wheel 4 through a belt 8, a fixed block 9 is fixedly installed on the top of the belt 8, the top of the fixed block 9 is hinged with a connecting rod 10, the other end of the connecting rod 10 is hinged with a lifting plate 11, the outer surface of the lifting plate 11 is movably connected to the inner surface of the working platform 3, the top of the lifting plate 11 passes through the working platform 3 and extends to the interior of the working platform 3, and the lifting plate 11 moves upward to block and position the carton.

[0030] When the transmission motor 5 is running, the transmission shaft 6 will drive the active circular wheel 7 to rotate, and the active circular wheel 7 will drive the driven circular wheel 4 to rotate through the belt 8, so that the belt 8 will rotate and drive the fixed block 9 to move to the left, so that the connecting rod 10 will rotate and squeeze to push the lifting plate 11 to move upward, thereby achieving the purpose of positioning and blocking the carton.

[0031] Among them, fixed plates 12 are fixedly installed on the front and rear sides of the top of the working platform 3, and a mounting plate 13 is fixedly installed on the left side of the top of the fixed plate 12.

[0032] The design of the fixing plate 12 serves to limit the position of the carton.

[0033] A pneumatic cylinder 14 is fixedly mounted on the top of the mounting plate 13 , and a bottom of the pneumatic cylinder 14 passes through the mounting plate 13 and extends to the bottom of the mounting plate 13 and is fixedly connected to a blade 15 .

[0034] When the pneumatic cylinder 14 is in operation, it will drive the blade 15 to move downward to trim the carton.

[0035] Among them, there are two fixed plates 12, and a rectangular plate 16 located on the right side of the mounting plate 13 is fixedly installed between the two fixed plates 12. A driving motor 17 is fixedly installed on the top of the rectangular plate 16. The other end of the output shaft of the driving motor 17 is fixedly sleeved with a rotating shaft 18, and the outer surface of the rotating shaft 18 is fixedly sleeved with a convex block 19.

When the convex block 19 rotates to the surface of the movable plate 22, the movable plate 22 will stretch the spring 21 to move downward to clamp and fix the carton. When the convex block 19 is reset, the elastic force of the spring 21 will restore the movable plate 22 to move upward for reset, thereby achieving the purpose of automatic clamping and fixing the carton.

[0045] When it is necessary to trim the carton to a fixed length, the transmission motor 5 is started, which will cause the transmission shaft 6 to drive the active circular wheel 7 to rotate. The rotation of the active circular wheel 7 drives the driven circular wheel 4 to rotate through the belt 8, and then the belt 8 rotates to drive the fixed block 9 to move to the left, so that the connecting rod 10 rotates and squeezes the lifting plate 11 to move upward to block and position the carton, thereby achieving the purpose of trimming the carton to a fixed length.
