Using a coated fresh-keeping machine can reduce the direct contact between fruits and vegetables and the air, thereby delaying the oxidation process and maintaining the freshness of fruits and vegetables. Secondly, it inhibits bacterial infection. The protective film formed by the coated fresh-keeping machine can also isolate bacteria to a certain extent, reducing the risk of bacterial infection of fruits and vegetables and further extending their shelf life.

However, the fresh-keeping machine still has the following defects when in use.

[0004] When the fresh-keeping machine covers fruits and vegetables with plastic wrap, a single station is required to cover the fruits and vegetables each time, take out the covered fruits and vegetables after covering, and then cover other fruits and vegetables again.

[0013] Technical effects and advantages of the present invention:

[0014] 1. The present invention utilizes a synchronous linkage wrapping mechanism. The electric cylinder pushes the connecting ring downward, and the connecting strip carries the sleeve block downward, and the sleeve block can slide down along the outer wall of the sliding column. The linkage plate drives the two pressure columns to move left, and another linkage plate drives the two pressure columns to move right.

[0015] 2. The present invention uses a synchronous linkage discharging mechanism. The controller starts the linkage electric cylinder, and the slip ring slides up along the outer wall of the pillar. At the same time, the slip ring drives multiple linkage bars to move up synchronously. The sliding push shaft carries the rotating frame to rotate counterclockwise, and the rotating frame drives the rotating rod to rotate counterclockwise. The rotating rod drives the rotating baffle to rotate counterclockwise, so that the rotating baffle rotates downward counterclockwise. The rotating baffle can open the space at the bottom of the coating box, and can synchronously discharge multiple coated fruits and vegetables. Synchronous diversion and external discharge of multiple coated fruits and vegetables can be achieved, which greatly improves the efficiency of fruit and vegetable coating and preservation.

[0016] 3. The present invention utilizes a material guide covering component, and supports two support shafts through a socket plate. The cling film roll can be limited between the support ring and the threaded ring for rotation. The winding motor is started by a controller, and the winding motor drives the winding roller to rotate. The winding roller drives the cling film roll to rotate. The cling film roll can slide on the covering box. During the covering process, two cling film rolls can be symmetrically covered and placed. Multiple covering boxes can be covered with cling film rolls, so that synchronous and efficient covering of fruits and vegetables can be achieved, and the efficiency of fruit and vegetable covering and preservation is greatly improved.

[0017] The above multiple functions interact with each other. First, during the coating process, the cling film on the two layers of cling film rolls are synchronously placed inside the multiple coating boxes. Secondly, the fruits and vegetables inside the multiple coating boxes are synchronously coated and cut. Finally, the multiple coated fruits and vegetables are synchronously discharged. In summary, each time the coating is performed, multiple fruits and vegetables can be synchronously coated and preserved in batches, and multiple coated fruits and vegetables can be synchronously diverted and discharged, which greatly improves the efficiency of fruit and vegetable coating and preservation.
