TECHNICAL FIELD

[0001] The utility model relates to the technical field of the push box of the modified atmosphere packaging machine, specifically to the box pushing mechanism of the modified atmosphere packaging machine. BACKGROUND

[0002] The modified atmosphere fresh-keeping packaging machine is a device that effectively preserves the packaged food by vacuumizing the air in the original packaging box and filling the mixed gas (nitrogen, oxygen, carbon dioxide) according to a certain ratio. The modified atmosphere packaging machine is classified into a box-type modified atmosphere packaging machine and a bag-type modified atmosphere packaging machine. After the box-type product is packaged, it needs to be pushed away from the processing position. This step will be assisted by a push box device.

[0003] For example, the box pushing mechanism of the modified atmosphere packaging machine with patent number "CN 221661157 U" is mentioned in the patent. The patent states: "The electric telescopic rod and the sliding push block do not connect with the lower end of the processing box body when moving and resetting. When a new round of box body is processed, the sliding push block repeats the above work to push the box. When the sliding push block moves back to its original position, it does not contact the upper end of the processing box. It does not need to wait for the sliding push block to return to its original position before placing and processing the new round of box."

[0004] The above-mentioned patent resets the push block while the processing box is placed for processing. This resetting process requires the cooperation of multiple components. An additional set of electric telescopic rods is needed for the vertical movement of the push block. The horizontal and vertical movements need to be coordinated, which results in a high cost of the device. In view of this, in-depth research has been conducted to solve the above-mentioned problems, and the present case has been produced. INVENTION CONTENTS
