The embodiment is specially used for packaging long-strip fruits and vegetables such as cucumbers, sheep horn honey, mangos and the like. Each lifting chain plate is fixedly provided with a group of lower die cylinders and lower die cores, and is driven by a transmission chain to do annular horizontal motion. When the initial state, when lifting the link joint and being located the orbital front end of lower mold core, lower mold core periphery wall can pass lower mold core perforation and be in upper limit, places rectangular shape fruit in the lower mold core this moment, and then lift the link joint and reach the fruit packing position in conveying fruit under drive chain's drive.

At the moment, the upper motor is started to rotate in the forward direction, the upper left screw rod and the upper right screw rod are driven to rotate in the forward direction, the upper die mounting plate is driven to move downwards, and the lower die core is kept in a static state. Until the upper mold core is propped against the lower mold core, the upper mold core can move downwards without being hindered due to the arrangement of the equal diameters of the outer diameters of the upper mold core and the lower mold core. In the process of moving the upper die cylinder downwards, the left ratchet wheel blocking piece and the right ratchet wheel blocking piece respectively block the left ratchet wheel and the right ratchet wheel from rotating, the left ratchet wheel and the right ratchet wheel respectively drag the mesh belt to move downwards along with the upper die cylinder until the mesh belt moves downwards along with the lower die cylinder to the lifting chain plate, and at the moment, the mesh belt is sleeved outside the lower die core. After the net sleeving action is finished, the left air cylinder drives the left push plate to push the left lower pull rod roller rightwards, the right air cylinder drives the right push plate to push the right lower pull rod roller leftwards, the left lower pull rod and the right lower pull rod move inwards relatively, then the left lower clamping jaw arm and the right lower clamping jaw arm are pushed to swing inwards, and until the left lower clamping jaw arm and the right lower clamping jaw arm swing to pass through a vertical central line where the articulated shaft is located, the left lower clamping block and the right lower clamping block press the net belt under the action of self weight, namely the left lower clamping block and the right lower clamping block press the net belt on the surface of an apple from the left side and the right side. And then, starting the upper motor to rotate reversely to drive the upper left screw rod and the upper right screw rod to rotate reversely, driving the upper die mounting plate to move upwards, namely enabling the upper die cylinder and the upper die core on the upper part to move upwards, and cutting the mesh belt when the cutter rotation driving motor drives the cutter to rotate horizontally after the upper die cylinder rises to a position above the cutter.

And then, the conveying chain is enabled to continue to drive the lifting chain plate to move forward until the conveying chain reaches between the left separation blade and the right separation blade, because the distance between the left separation blade and the right separation blade is smaller than the distance between the left push plate and the right push plate, the left lower clamping jaw and the right lower clamping jaw respectively move along the outer sides of the back guide inclined plates which are opposite to each other, the left lower clamping jaw and the right lower clamping jaw are respectively pulled open towards the left side and the right side by the two back guide inclined plates until the left lower clamping jaw arm and the right lower clamping jaw swing through the vertical central line where the articulated shaft is located, and the left lower clamping block and the right lower clamping block are opened towards the left side and the right side.

And the conveying chain continues to drive the lifting chain plate and the fruit sleeved with the mesh belt to move forwards until the fruit reaches the end of the front end of the lower mold core track, the push rod falls to the lower part of the lower mold core track to drive the lower mold core to move downwards to the lower part of the lifting chain plate, the fruit loses the support of the lower mold core at the moment, and the fruit can fall into the collecting area to finish unloading. When the transmission chain drives the lifting chain plate to continue to move to the rear end of the lower mold core track, the push rod can lift the slope of the lower mold core track, which is bent obliquely downwards, until the middle of the lower mold core track is reached, the lower mold core continuously rises at the moment, the lower mold core reaches the upper limit position, and then the next unpackaged fruit can be placed for the next packing operation.
