The L-shaped extending end of the abutting plate 16 is movably penetrated through the top of the cavity in the main shell 1 and located at the partition plate 3. The abutting plate 16 is movably penetrated through the rear end abutting plate 52 and the front end cutting knife plate 51. The surface of the penetrating end of the abutting plate 16 is provided with a limiting protrusion to prevent the end of the abutting plate 16 from sliding out of the front end cutting knife plate 51. When the upper rotating rod 103 is rotated, the abutting plate 16 is swung with the penetrating opening of the partition plate 3 as the fulcrum to avoid stagger and misalignment with the synchronous transversely moving cutting mechanism 5. At the same time, the abutting plate 16 is swung to contact the top of the packaging box to form lateral surface extrusion and fixation, thereby fixing the packaging film on the surface of the packaging box.

[0057] It should be noted that a groove is transversely formed in the middle of the partition plate 3. An upper pushing plate 18 is provided above the groove in the cavity of the main shell 1.

A film feeding mechanism 7 is rotationally arranged at the top of the cavity of the main shell 1 away from the partition plate 3. The film feeding mechanism 7 is used to feed the rolled packaging film to the surface of the receiving rod 43 (the packaging film uses a transparent film type with good adhesion and the cost is one half of that of a heat-shrinkable film. The width of the packaging film is set to be twice that of the packaging film to extend from the two side surfaces when covering the four surfaces of the packaging box, which facilitates the downward cutting of the side cutting mechanism 5 and folding of the extended part to cover the packaging box). The receiving rod 43 preliminarily winds the packaging film of the film feeding mechanism 7.

[0059] The inner surface of the film covering shell 41 is located on one side of the top of the receiving rod 43 and is rotatably provided with an upper smoothing wheel rod 44, and an lower smoothing wheel rod 45 is rotatably provided on one side of the upper smoothing wheel rod 44.

The inner surface of the film covering shell 41 is rotatably provided with an ejection wheel 49 at the bottom of the guide plate 48. The surface of the ejection wheel 49 protrudes on one side and is provided with an ejection plate. The extension length of the ejection plate can be adjusted by rotating the fixing screw on one side.

The spacing is less than the width of the packaging box. Under normal circumstances, the packaging box is transported from the outside to the position where the ejection plate 410 and the L-shaped top of the ejection groove plate 411 are flush. After the packaging box is covered with film, the ejection plate 410 is rotated to eject the packaging box from the ejection groove plate 411 to the transport mechanism 2.

[0064] The implementation principle of the three-dimensional packaging machine of the embodiment of the application is as follows: before the machine is started, the personnel first inserts the packaging film wound in the film feeding mechanism 7 through the receiving rod 43 between the upper flattening wheel rod 44 and the lower flattening wheel rod 45, between the upper clamping wheel rod 46 and the lower clamping wheel rod 47, and the guide plate 48 in sequence, and finally the packaging film is protruded at the extended end of the discharge plate 410 and aligned with the top of the push-up plate 18.

[0065] Then the feeding chute 6 transports the external packaging box into the cavity of the main shell 1, and the packaging box is transported in the process, and is located on the upper end surface of the packaging film, at this time, the personnel controls the rotating motor 15 to operate at intervals through the control system, when the feeding chute 6 transports the current packaging box to the surface of the packaging film, the feeding chute 6 stops running, the rotating motor 15 starts, and the motor end of the transmission rod 11 side starts;

[0066] The rotating motor 15 drives the rotating shaft 12 to rotate, so that the plurality of bevel gear sets 17 on the surface of the rotating shaft 12 operate to drive the rotating main rod 101 to rotate respectively, and the receiving rod 43, the upper flattening wheel rod 44, the lower flattening wheel rod 45, the upper clamping wheel rod 46, and the lower clamping wheel rod 47 are driven to rotate by the rotating gear set 42, and the upper clamping wheel rod 46 and the lower clamping wheel rod 47 rotate in opposite directions to clamp the packaging film, and at the same time, the packaging film is driven to move to one side of the discharge plate 410, and in the process of moving, the packaging film passes through the upper flattening wheel rod 44 and the lower flattening wheel rod 45, and is subjected to opposite rotation of the upper flattening wheel rod 44 and the lower flattening wheel rod 45 to fully contact the inclined surface pattern on the surface thereof to flatten the surface wrinkles, and finally the packaging film continuously moves to the surface of the discharge plate 410;

[0067] At the same time, the rotating main rod 101 drives the lower gear 106 and the upper gear 107 to rotate, and when the protruding part on the surface of the gear contacts the side surface of the lower linkage plate 105 and the upper linkage plate 104, it applies an outward pushing force to the lower linkage plate 105 and the upper linkage plate 104, and the lower linkage plate 105 is subjected to a pushing force to swing around the connection point of the rotating rod 102, thereby driving the rotating linkage 57 to move the push plate 55 to insert the fixed block 56 to move up and down, and in the process of moving the push plate 55, the rear end abutting plate 52 drives the front end cutting knife plate 51 and the two side cutting plates 53 to move up and down synchronously, thereby cutting the packaging film connection point on the surface of the packaging box;

[0068] In the process of cutting, the rear end abutting plate 52 abuts against one side of the packaging box, and under the transverse movement of the rear end abutting plate 52, the front end cutting knife plate 51 and the two side cutting plates 53, the abutting plate 16 is driven to abut against the side surface of the packaging box (by rotating the upper rod 103 to drive the abutting plate 16 to swing around the through point of the partition plate 3 as a fulcrum, thereby preventing misalignment between the front end cutting knife plate 51 and the abutting plate 16 caused by transverse movement), and in the process of swinging and abutting of the abutting plate 16, the packaging film folded along one side of the packaging box is folded again, so that the packaging film covers the top of the packaging box;

[0069] At this time, the packaging film is attached to the surface of the packaging box, the discharge plate 410 is driven to rotate by the rotating gear set 42, so that the discharge plate 410 and the discharge groove plate 411 at the top are not in a flat state, thereby making the packaging box after film covering fall into the discharge groove plate 411, and the surface of the discharge plate is driven to rotate by the discharge wheel 49, and is conveyed to the outside low-temperature sealing structure by the conveying mechanism 2, and the guide rod 13 and the limiting plate 14 arrange and limit the left side margin of a plurality of packaging boxes, so that the plurality of packaging boxes are accurately conveyed to the top of the discharge plate 410 and the discharge groove plate 411 to align the surface, and are orderly discharged to the outside, thereby forming an integrated operation process of the film covering mechanism 4, the cutting mechanism 5 and the rotating rod set 10 driven by the rotating shaft 12, simplifying the operation process and effectively improving the production efficiency.

[0070] The above merely provides the optional embodiments of the present application, but does not limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall fall into the protection scope of the present application.
