Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0023] Please see the attached Figure 1 -Attached Figure 2

[0024] A fruit film coating and boxing device includes a device body 1, a shell 2 with an open bottom is provided on the device body 1, an inlet 3 is provided on the shell 2 for placing fruit, and a plastic wrap winding device 4 is provided on both sides of the shell 2. The plastic wrap winding device 4 belongs to the existing technology, for example, it includes a motor device that can be rotated forward and reverse and a roller for installing a plastic wrap tube, etc., which will not be described in detail here; a plastic wrap body 6 is provided between the two groups of plastic wrap winding devices 4. The material of the plastic wrap body 6 of the present application can preferably be prepared by chitosan film liquid, ferulic acid, sodium alginate film, etc. For example, an edible composite film and its preparation method and use proposed in Publication No. CN108639564B have been disclosed.

[0025] The cling film body 6 extends into the shell 2, and the two ends of the cling film body 6 respectively pass through the two sides of the shell 2 so as to be wound on the two cling film winding devices 4; a guide component corresponding to the inlet 3 is provided in the inner cavity of the shell 2 and located outside the cling film body 6. The guide component is used to drive the cling film body 6 to cover the fruit entering from the inlet 3 when the two cling film winding devices 4 unwind the cling film body 6. Figure 2 state;

[0026] A placement platform 11 is provided on the device body 1 below the housing 2 and is driven up and down by a telescopic device 10. A fresh-keeping box 12 corresponding to the guide assembly is placed on the placement platform 11 for containing fruits covered with the fresh-keeping film body 6;

[0027] A limiting cutter is provided above the fresh-keeping box 12. This is used to wrap the fruit with the plastic wrap body 6 and cut off the outer wall of the plastic wrap body 6, allowing the fruit to fall into the fresh-keeping box 12 along with the fruit. The limiting cutter moves upward along with the telescopic device 10, gradually forcing the plastic wrap body 6 to retract inward, and then cuts off the plastic wrap body 6. This, on the one hand, separates the portion of the plastic wrap body 6 wrapped around the fruit from the rest of the plastic wrap body 6 on the plastic wrap winding device 4, allowing it to be used to wrap other fruit. On the other hand, it allows the fruit wrapped in the plastic wrap body 6 to move downward into the fresh-keeping box 12.

[0028] Please see the attached Figure 3

[0029] Preferably, the guide component of this embodiment includes:

[0030] There are two sets of upper limit plates 7, which are located on both sides of the inlet 3 and fixed in the shell 2. The two sets of upper limit plates 7 are used to guide the fruits entering from the inlet 3 so that the fruits fall on the plastic wrap body 6; and

[0031] The lower limit plate 8 is provided with two groups, which correspond to the upper limit plate 7 and are fixed in the shell 2. The lower limit plate 8 enables the cling film winding device 4 to unwind the cling film body 6, so that the cling film body 6 can be wrapped around the outside of the fruit under the action of the gravity of the fruit. Figure 2 As shown;

[0032] The upper limit plate 7 and the lower limit plate 8 are both provided at opposite ends with guide rollers 9 for fitting with the outer wall of the cling film body 6 so as to guide the cling film body 6 .

[0033] Preferably, the limiting cutting member of this embodiment includes:

[0034] The limiting ring 13 is detachably arranged above the fresh-keeping box 12. The axis of the limiting ring 13 is located at the center of the guide assembly. The inner diameter of the limiting ring 13 is larger than or matches the diameter of the inlet, so that the fruit wrapped with the plastic wrap body 6 passes through the limiting ring 13 and falls downward into the fresh-keeping box 12. The diameter of the limiting ring 13 is smaller than the width of the plastic wrap body 6, which is convenient for cutting a circular portion on the plastic wrap body 6. Subsequently, the plastic wrap winding device 4 on one side can be driven to unwind the plastic wrap body 6 and the other plastic wrap body 6 can be driven to rewind the plastic wrap body 6, so that the uncut portion of the plastic wrap body 6 can be re-aligned with the inlet, which is convenient for wrapping the next fruit; and

[0035] There are two groups of fan-shaped plates 17, which are symmetrically slidably arranged on the top of the limit ring 13. The two groups of fan-shaped plates 17 are provided with electric heating cutting blades 18 on the opposite side. The two groups of fan-shaped plates 17 are driven by the telescopic device 16 to move relative to the limit ring 13. The telescopic device 16 drives the two groups of fan-shaped plates 17 to move closer to or away from each other, and the electric heating cutting blades 18 cut the cling film body 6, so that the cling film body 6 wrapped around the fruit is partially separated from the original cling film body 6.

[0036] Preferably, the limiting ring 13 of this embodiment is located on the inner side of the two groups of brackets, and the two groups of brackets are fixed to the placement platform 11. A threaded rod 14 is threadedly inserted on the opposite side of the two groups of brackets, and the outer end of the threaded rod 14 is provided with a driving handwheel for the user to rotate. The end of the threaded rod 14 facing the limiting ring 13 is provided with a block 15 through a bearing. The block 15 is inserted into the block hole opened on the side wall of the limiting ring 13, and the side of the block 15 away from the limiting ring 13 is provided with a guide rod horizontally passing through the bracket, which limits the block 15 from being driven to rotate by the threaded rod 14. Through this arrangement, it is convenient to replace limiting rings 13 of different specifications for use to adapt to fruits of different specifications.

[0037] As a preference, a pressure sensor 5 is provided at the bottom of the guide assembly of this embodiment. For example, a pressure sensor 5 of model HX711 may be used. Of course, this is not limited to this model.

[0038] The pressure sensor 5 is electrically connected to the external controller and is used to send a signal to the external controller when receiving the pressure signal of the fan plate 17, so that the external controller controls the telescopic device 2 16, the electric heating cutting blade 18 and the telescopic device 10. Specifically, when the fan plate 17 contacts the pressure sensor 5, the external controller controls the telescopic device 2 16 to work, controls the telescopic device 10 to stop working, and controls the electric heating cutting blade 18 to work.

[0039] Preferably, the side wall of the housing 2 of this embodiment is provided with a transparent window so that the user can observe the position of the fruit wrapped with the plastic wrap body 6 from the outside to operate the device.

[0040] Working principle: Place the fresh-keeping box 12 on the placement platform 11, put the fruit into the shell 2 from the inlet 3, and the fruit falls on the plastic wrap body 6 between the two sets of upper limit plates 7. Then, the two plastic wrap winding devices 4 rotate in opposite directions to unwind the plastic wrap body 6, and then the plastic wrap body 6 moves downward to cover the fruit (such as Figure 2State), control the telescopic device 10 upward and the limit ring 13 upward, so that the plastic wrap body 6 is wrapped around the outer wall of the fruit, until the sector plate 17 contacts the pressure sensor 5, the external controller controls the telescopic device 2 16 to work, controls the telescopic device 10 to stop working, and the electrically heated cutting blade 18 to work. The telescopic device 2 16 drives the sector plates 17 to move inward, and the two groups of sector plates 17 contact each other, so that the fruit wrapped in the plastic wrap body 6 and the part of the plastic wrap body 6 covering its outer wall fall downward through the electrically heated cutting blade 18, and pass through the opening on the limit ring 13 and fall into the fresh-keeping box 12, and then drive the telescopic device 10 to drive the placement platform 11 to reset downward;

[0041] Then, one cling film winding device 4 is driven to rewind the cling film body 6, and the other cling film winding device 4 is driven to unwind the cling film body 6, and the uncut area on the cling film body 6 is used to wrap and box the next fruit.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
