DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0029] Reference Figures 1 to 5 As shown, in one embodiment of the utility model, a toy heat shrink film packaging device includes a first conveyor belt 1, a second conveyor belt 2 and a tunnel furnace 3 which are connected in sequence, and the first conveyor belt 1 conveys the toy to the second conveyor belt 2;

[0030] A protective cover 11 is provided on the first conveyor belt 1, and the toys on the first conveyor belt 1 will pass through the toys. A plurality of fans 12 are arranged at intervals on the protective cover 11 along the conveying direction of the first conveyor belt 1, and the fans 12 blow air toward the toys on the first conveyor belt 1 to ensure that the toys are free of moisture when they are conveyed to the second conveyor belt 2 and contact the heat shrink film;

[0031] The second conveyor belt 2 is provided with a film supporting structure 4, a film closing structure 5, a waste edge winding structure 6 and a cutting structure 7 in sequence along its conveying direction, and also includes a film roll 8 located below the second conveyor belt 2. The heat shrinkable film is pulled out from the film roll 8 and passes through the film supporting structure 4, the film closing structure 5 and the waste edge winding structure 6 in sequence.

[0032] The film supporting structure 4 makes the middle part of the heat shrink film concave, so that the heat shrink film presents a U shape, and the toys output by the first conveyor belt 1 fall into the concave part of the heat shrink film; the upper ends of both sides of the heat shrink film will pass through the film closing structure 5, and the film closing structure 5 will heat-seal the upper end of the heat shrink film, so that a heat-sealing line extending along its conveying direction appears on the heat shrink film, and the part of the heat shrink film above the heat-sealing line is the waste edge; the waste edge rolling structure 6 pulls the heat shrink film to move by rolling up the waste edge; then, the cutting structure 7 cuts and heat-seals the heat shrink film between two adjacent toys, so that the heat shrink film forms an independent bag body to wrap the toy, and then the toy is moved to the tunnel furnace 3, and the heat shrink film shrinks and fits on the surface of the toy, so that the heat shrink film can be packaged on the surface of the toy in an assembly line manner.

[0033] In this embodiment, the film support structure 4 includes a support plate 41 arranged at the input end of the second conveyor belt 2, and both sides of the support plate 41 along the conveying direction of the second conveyor belt 2 are provided with a limit plate 42, and the limit plate 42 is inclined upward along the conveying direction of the second conveyor belt 2, and the end of the support plate 41 close to the first conveyor belt 1 is butted against the lower end of the limit plate 42;

[0034] Two expansion rods 43 are provided at one end of the support plate 41 close to the first conveyor belt 1. The two expansion rods 43 are arranged on both sides of the support plate 41 along the conveying direction of the second conveyor belt 2. The expansion rods 43 extend horizontally. The distance between one end of the expansion rod 43 connected to the support plate 41 and the first conveyor belt 1 is smaller than the distance between one end of the expansion rod 43 away from the support plate 41 and the first conveyor belt 1, so that the expansion rod 43 is inclined.

[0035] After the heat shrink film is pulled out, it first passes through the support plate 41 close to one end of the first conveyor belt 1. At this time, the two sides of the heat shrink film will be placed on the expansion rod 43, and then, the two sides of the heat shrink film will pass over the limit plate 42, so that the two sides of the heat shrink film will be bent. At this time, the middle part of the heat shrink film is concave, and the heat shrink film is U-shaped. The inclined arrangement of the expansion rod 43 can prevent the heat shrink film from being pulled too much and broken when passing over the limit plate 42.

[0036] In this embodiment, a baffle 44 is provided on one side of the limiting plate 42 close to the heat shrink film, and the U-shaped heat shrink film will pass through between the two limiting plates 42, and the upper ends of both sides of the heat shrink film will be located below the baffle 44 and contact with the baffle 44. In this way, the upper ends of both sides of the heat shrink film will not rise and bend inward, ensuring that the heat shrink film is fully opened between the limiting plates 42, and the toy can easily enter the recess.

[0037] In this embodiment, a third conveyor belt 9 is provided above the second conveyor belt 2. The third conveyor belt 9 is located between the film closing structure 5 and the cutting structure 7 to press the heat shrink film downward. The running speed of the second conveyor belt 2 is consistent with the running speed of the third conveyor belt 9.

[0038] After the heat shrink film passes through the film-closing structure 5, both sides of the heat shrink film will be heat-sealed. At this time, the heat shrink film is protruding upward and has a pointed end. If this part is directly heat-shrunk, it may not be able to fit to the surface of the toy, affecting the appearance; therefore, a third conveyor belt 9 is provided, and the spacing between the third conveyor belt 9 and the second conveyor belt 2 is adjusted. After the toy enters under the third conveyor belt 9, the third conveyor belt 9 will smooth out this part of the protruding heat shrink film, so that the heat shrink film is as close to the toy surface as possible; and the speeds of the second conveyor belt 2 and the third conveyor belt 9 are controlled to be consistent, ensuring that the toy can move at the original spacing without affecting the subsequent cutting.

[0039] Preferably, an elastic layer 91 is laid on the belt surface of the third conveyor belt 9, and a groove 92 extending along the moving direction thereof is provided on the elastic layer 91, and the groove 92 accommodates the toys on the second conveyor belt 2;

[0040] The groove 92 is used to locate the moving path of the toy, and the elastic layer 91 is used to provide pressure to press the heat shrink film so that the heat shrink film is as close to the surface of the toy as possible.

[0041] Preferably, a plurality of expansion joints 93 are arranged side by side on the elastic layer 91, and the expansion joints 93 extend from the grooves 92 to both sides of the elastic layer 91 along its moving direction. The extension direction of the expansion joints 93 is perpendicular to the conveying direction of the third conveyor belt 9. Because the elastic layer 91 moves following the belt surface of the third conveyor belt 9, and the belt surface moves in a circular motion, the expansion joints 93 can allow the elastic layer 91 to adapt to deformation at the turning position.

[0042] In this embodiment, the elastic layer 91 is a sponge, and the sponge is fixed to the belt surface of the third conveyor belt 9 by means of glue.

[0043] In this embodiment, the film-closing structure 5 includes a first heating plate and a second heating plate arranged side by side, the first heating plate and the second heating plate are both rotatable, the rotation axes of the first heating plate and the second heating plate are both in the vertical direction, the outer wall of the first heating plate is provided with an annular cutter, the outer wall of the second heating plate is provided with an annular groove, the upper ends of both sides of the heat shrinkable film pass through between the first heating plate and the second heating plate, and the annular cutter presses the heat shrinkable film into the annular groove, thereby forming a heat seal line on the heat shrinkable film;

[0044] Specifically, gears are provided at the upper ends of the first heating plate and the second heating plate, and the two gears are meshed with each other, and one of the gears rotates when driven by the motor, thereby driving the first heating plate and the second heating plate to rotate.

[0045] In this embodiment, the scrap edge winding structure 6 includes a reel and a driving module for driving the reel to rotate. One end of the scrap edge is fixed to the reel, and the scrap edge is wound up by the rotation of the reel.

[0046] In this embodiment, the cutting structure 7 includes a hot cutting knife and a cylinder for driving the hot cutting knife to rise and fall. The hot cutting knife is located between the second conveyor belt 2 and the tunnel furnace 3. The hot cutting knife uses the gap between the second conveyor belt 2 and the tunnel furnace 3 to cut the heat shrink film and seal the heat shrink film.

[0047] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
