Description

Technical Field

[0001] The utility model relates to the technical field of winding film packing machines, in particular to a chassis structure of a winding film packing machine. Background Art

[0002] In the existing patents, the Chinese patent document with the application number 202220606599.3 discloses a winding film packing machine, which includes a packing box. A base is fixedly connected to the bottom of the packing box. A support plate is fixedly installed on one side of the packing box. An adjusting and replacing mechanism is arranged on the support plate. A synchronous winding mechanism is arranged inside the packing box. The adjusting and replacing mechanism includes a cylinder, a lower rotating column and a connecting plate. The bottom of the cylinder is fixedly installed on the top of the support plate. A moving groove is formed on the surface of the support plate. A limiting groove is formed inside the support plate and located inside the moving groove. The bottom of the cylinder is slidably connected with a piston rod. The bottom end of the piston rod penetrates and extends to the limiting groove. A limiting block is fixedly connected to one side of the connecting plate. The surface of the limiting block is slidably connected with the inner surface of the limiting groove. The top of the limiting block is fixedly connected with the bottom end of the piston rod. The bottom of the connecting plate is rotatably connected with an upper rotating column. Grooves are formed on the surfaces of the lower rotating column and the upper rotating column. The synchronous winding mechanism includes a driving motor. The driving motor is fixedly installed at the bottom of the inner cavity of the packing box. One end of the output shaft of the driving motor is fixedly connected with a driving rotating shaft through a coupling. The top end of the driving rotating shaft is fixedly connected with the bottom of the lower rotating column. The surface of the driving rotating shaft makes a driven rotating shaft rotate through a transmission component. The outer surface of the driven rotating shaft makes a supporting rotating shaft rotate through an engaging component. The driving motor of this patent document is located at the bottom of the inner cavity of the packing box, making it inconvenient to disassemble and assemble the driving motor. Moreover, when disassembling the driving motor, the transmission component needs to be disassembled first before the driving motor can be disassembled.

[0003] In addition, the Chinese patent document with the application number 201510851410.1 discloses a packing box winding film machine with accurate winding film rising, which includes a turntable, a driving motor, a driving cylinder, a protective film mounting seat and a frame. The driving motor is installed on the frame. The driving motor is connected to the turntable rotatably arranged on the frame through a belt. A packing box positioning angle is arranged on the turntable. A laser generator is also arranged on the turntable. A laser receiver is arranged on one side of the disc. The driving cylinder is arranged below the frame. The driving end of the driving cylinder is connected to the protective film mounting seat. A rotatable rotating shaft is arranged on the protective film mounting seat. The laser receiver is electrically connected to the driving motor. Although the driving motor of this patent document is installed on the frame, before disassembling the driving motor, the transmission components such as the belt need to be disassembled first, resulting in inconvenient disassembly and assembly of the driving motor.

[0004] Therefore, the defects are very obvious and a solution is urgently needed. Summary of the Utility Model

The output shaft of the motor 6 passes through the through hole and is inserted into the central hole of the driving wheel 8. The output shaft of the motor 6 is key-connected to the driving wheel 8.

[0022] In practical applications, the motor 6 drives the driving wheel 8 to rotate. The rotating driving wheel 8 drives the driven wheel 9 to rotate via the transmission strip 10.
