The foamed polyethylene net has good elasticity and softness, can effectively play roles of buffering and vibration prevention, and is widely applied to fruit packaging.

The existing fruit net sleeve packaging device has the problem that the packaging quality is not stable enough. For example, chinese patent CN 105015827B discloses a small-sized automatic apple net packing machine, which adopts a mechanical claw to install an upper sleeve, and since the upper sleeve is not fixed, there is a risk that the upper sleeve falls off when a fruit is not loaded. Chinese patent CN 111017293 a discloses an automatic apple net packing machine, wherein a net cutting device cuts off the net below the fruits, so that the net not wrapped on the fruits is completely separated from a net traction device, resulting in the defect that the net can not be fed again after being cut. Meanwhile, the existing net cover packaging device is mostly aimed at spherical fruits, and automatic net cover operation can not be carried out on fruits with long fruit stalks. At present, the packaging of fruits with long fruit stalks is basically completed manually, and the problems of high labor cost, low efficiency, uneven packaging quality and the like exist.

In view of the above-mentioned drawbacks and the current demand for the mesh packaging of spherical fruits, especially fruits with long fruit stalks, it is desirable to provide a mesh device that is simple and safe to operate, so as to solve the problems of high cost, low efficiency, poor quality, etc. of the existing mesh packaging, and to achieve the automation of fruit mesh packaging.

step 2: the net material 100 is conveyed through the net conveying mechanism 1, so that the end part of the net material 100 is stretched by the net stretching inner cylinder 21 and then moves downwards along the outer wall of the net stretching inner cylinder 21 until the end part of the net material 100 is folded outwards along the guide wings 211 to form a folding part;

And 3, repeating the operations of the step 1 to the step 9 to perform the netting operation of the next fruit until all the fruits to be netted are netted.

In the present invention, the operation of each of the above-described mechanisms is controlled by the control system 10 (for example, the PLC control system 10), and the operation is highly accurate and simple.

The operation of the automatic fruit netting device of the present invention will be described in detail below.

The first step is as follows: each mechanism is reset to its respective home position under the control of the control system 10.

The second step is that: under the control of the control system 10, the conveyor belt 7 conveys the (long stalk) fruit to the tray 51.

The third step: the control system 10 controls the net supporting motor 26 to rotate in the forward direction, so as to drive the inner cylinder bracket 28 and the net supporting inner cylinder 21 to move upwards to enter the inside of the net sleeving outer cylinder 31, and the net supporting motor 26 stops rotating until the first preset position is reached.

The fourth step: the control system 10 controls the mesh expanding motor 22 to rotate in the forward direction, so as to drive the transmission disc 24 to rotate in the forward direction, further drive the transmission rod 25 to rotate in the forward direction, and further drive the mesh expanding roller 23 to rotate in the forward direction.

The fifth step: the control system 10 controls the two net feeding motors 14 of the net feeding mechanism 1 to rotate in opposite directions, so as to drive the two net feeding rollers 12 to rotate in opposite directions, and further convey the end part of the net material 100 to the top end of the net supporting inner cylinder 21. Under the action of the mesh expanding roller 23 and the two mesh conveying rollers 12 rotating oppositely, the mesh material 100 is expanded by the mesh expanding inner cylinder 21 and moves downwards along the outer wall of the mesh expanding inner cylinder 21.

And a sixth step: the end of the net material 100 is folded outwards under the action of the arc-shaped guide wings 211 of the net-stretching inner cylinder 21 to form a folded part, and the folded part enters between the elastic sheet 33 and the wedge-shaped protrusion 34 of the clamping assembly. At this time, the grid expanding motor 22 and the two grid feeding motors 14 stop rotating. Then, the control system 10 controls the telescopic rod of the telescopic cylinder 32 to extend downwards, so that the elastic sheet 33 is attached to the wedge-shaped protrusion 34, thereby fixing the folded part and keeping the end of the net material 100 in the unfolded state.

The seventh step: the control system 10 controls the net cutting motor 41 to rotate forward to drive the heating wire 43 to cut off the net material 100 to form a net sleeve, so as to complete the net cutting action, and after the net cutting is completed, the net cutting motor 41 rotates reversely to return the heating wire 43 to its initial position.

Eighth step: the control system 10 controls the grid-supporting motor 26 to rotate in the reverse direction, so as to drive the inner cylinder bracket 28 and the grid-supporting inner cylinder 21 to move downwards. Meanwhile, the control system 10 controls the mesh expanding motor 22 to rotate reversely, so as to drive the transmission disc 24 to rotate reversely, so as to drive the transmission rod 25 to rotate reversely, so as to drive the mesh expanding roller 23 to rotate reversely. After the net supporting inner cylinder 21 exits the net sleeving outer cylinder 31, the net expanding motor 22 stops rotating. When the net-supporting inner cylinder 21 returns to its initial position, the net-supporting motor 26 stops rotating.

The ninth step: the control system 10 controls the fruit feeding motor 53 to rotate forward, so that the tray 51 is driven to move towards the screen sleeving mechanism 3 along the horizontal direction, the tray 51 passes through the space between the turning block 61 and the turning rod 62 until the second preset position right below the screen sleeving outer cylinder 31 is reached, and the fruit feeding motor 53 stops rotating.

The tenth step: the control system 10 controls the netting motor 36 to rotate forward, so as to drive the outer cylinder bracket 38 and the netting outer cylinder 31 to move downwards until the lower end of the netting outer cylinder 31 contacts with the tray 51, and the netting motor 36 stops rotating. The control system 10 then controls the telescopic rod of the telescopic cylinder 32 to retract upwards, so that the elastic sheet 33 springs up and away from the wedge-shaped protrusion 34, thereby releasing the net cover. Thereby completing the fruit netting operation.

The eleventh step: the control system 10 controls the netting motor 36 to rotate in reverse, so as to drive the tub support 38 and the netting tub 31 to move upward until the original position is returned, and the netting motor 36 stops rotating.

The twelfth step: the control system 10 controls the fruit feeding motor 53 to rotate reversely, so that the tray 51 moves in a direction away from the net covering mechanism 3 along a horizontal direction, when the guide plate 513 of the tray 51 contacts with one end of the turning plate 61 close to the net covering mechanism 3, the guide plate 513 moves upwards along the inclined surface of the turning plate 61, and the tray 51 rotates (inclines) upwards by taking the sliding shaft 52 as an axis, and when the inclined angle of the tray 51 reaches a certain angle, the fruit covered on the tray 51 is turned out of the tray 51. The tray 51 continues to move until it returns to its initial position and the fruit feeding motor 53 stops rotating.

The fruit netting operation can be completed by the steps.
