[0027] like Figure 1-4 As shown, the utility model proposes a film-opening device for a box tray packaging film, including a film-tearing platform, which includes a horizontally arranged roller conveyor 1, a lifting platform installed above the right feeding tail end of the roller conveyor 1, and a baffle 11 for positioning the box tray is provided at the tail end of the roller conveyor 1. The box tray with packaging film is conveyed from left to right to the baffle 11 and reaches the limit position, at which time it is just below the lifting platform, thereby effectively positioning the position of the box tray.

[0028] The lifting platform includes a bracket 22, a lifting plate 21 and a first telescopic cylinder 23. The bracket 22 is installed on both sides of the roller conveyor 1. The lifting plate 21 is horizontally arranged and slidably installed on the bracket 22. The first telescopic cylinder 23 is vertically installed on the bracket 22, and its piston rod is fixedly connected to the lifting plate 21. The lifting plate 21 is driven up and down by the first telescopic cylinder 23, thereby driving the heating cutter 3, the upper suction cup assembly 71, the film feeding mechanism and other mechanisms to move up and down synchronously, thereby realizing a rapid film tearing action.

[0029] Corresponding heating cutters 3 are arranged on the sides of the box holder below the lifting plate 21, and four heating cutters 3 are connected to the corresponding horizontal drive components installed on the lifting platform. Among them, the heating cutter 3 adopts the structure of the electric heating cutter 3 in the prior art. The horizontal drive component includes four second telescopic cylinders 31, and the four second telescopic cylinders 31 are horizontally installed below the lifting plate 21. The piston rod of each second telescopic cylinder 31 is fixedly connected to the corresponding heating cutter 3. The corresponding heating cutter 3 is driven to approach the side wall of the box holder by the second telescopic cylinder 31, so that the packaging film is cut from the middle of the box holder by the high-temperature heating cutter 3, which can realize the quick disconnection operation of the packaging film and make the separation of the packaging film more efficient.

[0030] An upper suction cup assembly 71 is provided at the bottom of the lifting plate 21, and a lower suction cup assembly 72 is correspondingly provided above the film tearing platform. The multiple suction cups included in the two suction cup assemblies are all connected to an external negative pressure source. The lower suction cup assembly 72 and the supporting mechanism are both arranged below the roller gap of the roller conveyor 1. When the lifting platform moves downward, the upper suction cup assembly 71 can move downward with it and absorb the packaging film on the top of the box tray, while the packaging film at the bottom of the box tray is absorbed by the lower suction cup assembly 72. After the heating cutter 3 cuts the packaging film, the lifting platform is used to drive the upper suction cup assembly 71 to rise, so that the packaging film above the box tray can be torn off the box tray.

[0031] A supporting mechanism for lifting the box holder upward is also provided below the film tearing platform. The supporting mechanism includes a third telescopic cylinder 8, which is vertically installed upward below the roller gap of the roller conveyor 1. When the upper suction cup assembly 71 tears the cut upper packaging film, the lower packaging film is sucked by the lower suction cup assembly 72, and the box holder body is lifted up by the upward movement of the third telescopic cylinder, so that the lower packaging film can be torn off the box holder, and then the box holder body is pushed to the unloading port 10 on the side of the roller conveyor 1 by the material diverting mechanism provided on one side of the film tearing platform.

[0032] A feeding conveyor 12 is provided at the feeding port 10 on the other side of the film tearing platform away from the material-discharging mechanism. The box tray with the packaging film torn off is pushed to the feeding conveyor 12 through the feeding port 10 by the material-discharging mechanism, and is sent to the next process by the feeding conveyor 12. Among them, the material-discharging mechanism includes a fourth telescopic cylinder 43 and a push plate 41. The push plate 41 is opposite to the feeding port 10 and is horizontally arranged on the side of the box tray. The fourth telescopic cylinder 43 is horizontally installed perpendicular to the push plate 41 below the roller conveyor 1. The push plate 41 is fixedly connected to the piston rod of the fourth telescopic cylinder 43 through a connecting plate 42 that penetrates the gap between the rollers. When the fourth telescopic cylinder 43 is in motion, the push plate 41 is driven to move backward horizontally through the connecting plate 42, so that the box tray on the roller conveyor 1 can be smoothly sent to the feeding port 10, and the film tearing operation of disconnecting the packaging film below is completed.

[0033] The lifting platform is also vertically provided with a film feeding mechanism, which is used to feed the torn packaging film to the heating and compression assembly provided below the film tearing platform. The film feeding mechanism includes a fifth telescopic cylinder 5 vertically downwardly installed on the lifting platform, and the piston rod of the fifth telescopic cylinder 5 penetrates the roller gap of the roller conveyor 1 and is provided corresponding to the feed port of the heating roller 60 assembly. After the packaging film is torn off by the box holder, the packaging film adsorbed on the upper suction cup assembly 71 and the lower suction cup assembly 72 can be sent to the heating roller 60 assembly through the roller gap by using the downward extension action of the fifth telescopic cylinder 5 for centralized processing, which is more convenient for the collection and processing of the packaging film.

[0034] The heating and compression assembly is used to heat and extrude the torn packaging film into a sheet. The heating and compression assembly includes two heating rollers 60 and a shell 6 that rotate in opposite directions. The shell 6 is installed below the roller conveyor 1, and the two heating rollers 60 are rotatably installed in the shell 6.

The ends of the rotating shafts of the two heating rollers 60 are coaxially mounted with a second gear 6362, and the two second gears 6362 are meshed. The output shaft of the motor installed on the shell 6 is mounted with a second gear, and the second gear is meshed with one of the second gears 6362. A receiving tray 61 is provided at the discharge port below the shell 6. The power of the motor is transmitted to the two second gears 6362 through the second gear, thereby driving the two heating rollers 60 to rotate in opposite directions, so that the packaging film from the film feeding mechanism can be heated and squeezed, so that the packaging film is compressed into a sheet and then collected in the receiving tray 61, which is more convenient for the subsequent recycling of the packaging film.

[0035] When the utility model is used, after the box tray is transported by the roller conveyor 1 to the limit position of the baffle 11, the first telescopic cylinder 23 is actuated to drive the lifting plate 21 to descend; then the second telescopic cylinder 31 drives the heating cutter 3 to move, so that it is close to the outer packaging film of the box tray, and the heating cutter 3 cuts the packaging film by high temperature; the two suction cup assemblies located at the upper and lower parts of the box tray use negative pressure to absorb the cut packaging film, and the first telescopic cylinder 23 drives the lifting plate 21 to rise, so that the broken packaging film above the box tray is separated from the box tray; the third telescopic cylinder located below the box tray lifts the box tray , so that the broken packaging film under the box tray is completely separated from the box tray; the fourth telescopic cylinder 43 drives the push plate 41 to move horizontally, and sends the box tray on the roller conveyor 1 to the unloading conveyor 12 through the unloading port 10; the fifth telescopic cylinder 5 extends downward, and the packaging film adsorbed on the two suction cup assemblies can be sent to the heating roller 60 assembly through the roller gap. The two heating rollers 60 rotate in opposite directions, so that the packaging film from the film feeding mechanism can be heated and squeezed, so that the packaging film is compressed into sheets and then collected in the receiving tray 61, and the box tray film removal action is completed.
