Description

Technical Field

[0001] This invention belongs to the field of pharmaceutical processing, and specifically relates to a device for opening a box tray packaging film. Background Technology

[0002] In the medicine bottle filling process, empty medicine bottles are usually placed in trays wrapped with packaging film. The packaging film on the trays needs to be torn off before the medicine bottles in the trays can be further filled, sealed, and printed. Currently, the unwrapping operation of the packaging film on the trays is all done manually, which is not only inefficient but also time-consuming and labor-intensive, seriously affecting the processing efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention aims to provide a box tray packaging film tearing device. This device can efficiently and quickly tear the outer packaging film of the box tray, and can also effectively collect and process the torn packaging film, making it more labor-saving and efficient, thereby significantly improving processing efficiency.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A box tray packaging film opening device includes a film-tearing platform, a lifting platform above the film-tearing platform, and a lifting platform including a bracket, a lifting plate, and a first telescopic cylinder. The bracket is mounted on a roller conveyor. The lifting plate is horizontally positioned and slides vertically on the bracket. The first telescopic cylinder is vertically mounted on the bracket, and its piston rod is fixedly connected to the lifting plate. Four heated cutting blades are provided on the four sides of the box tray below the lifting plate, and these four blades are connected to corresponding horizontal drive components mounted on the lifting plate. An upper suction cup assembly is provided at the bottom of the lifting plate, and a lower suction cup assembly is provided above the film-tearing platform. Both suction cup assemblies are connected to an external negative pressure source. A lifting mechanism for lifting the box tray upwards is also provided below the film-tearing platform. A feeding mechanism for pushing the box tray towards the discharge port on one side of the film-tearing platform is provided on one side. A film feeding mechanism is also vertically provided on the lifting plate, which feeds the torn packaging film to a heating and compression assembly below the film-tearing platform. The heating and compression assembly heats and compresses the torn packaging film into a sheet. A discharge conveyor is also provided at the discharge port.

[0005] Preferably, the film-tearing platform includes a horizontally arranged roller conveyor, and the lower suction cup assembly and the top support mechanism are both located below the roller gap of the roller conveyor; the lifting platform is installed at the material conveying tail end of the roller conveyor, and a baffle for positioning the box support is provided at the tail end of the roller conveyor.

[0006] Preferably, the horizontal drive assembly includes a second telescopic cylinder, which is horizontally installed below the lifting plate, and the piston rod of the second telescopic cylinder is fixedly connected to the corresponding heated cutter.

[0007] Preferably, the top support mechanism includes a third telescopic rod, which is installed vertically upward below the roller gap of the roller conveyor.

[0008] Preferably, the feeding mechanism includes a fourth telescopic cylinder and a push plate. The push plate is horizontally positioned on the side of the box holder opposite to the feeding port. The fourth telescopic cylinder is horizontally installed below the roller conveyor perpendicular to the push plate. The push plate is fixedly connected to the piston rod of the fourth telescopic cylinder by a connecting plate that passes through the gap between the rollers.

[0009] Preferably, the film feeding mechanism includes a fifth telescopic cylinder mounted vertically downward on the lifting plate, and the piston rod of the fifth telescopic cylinder is arranged to pass through the gap between the rollers of the roller conveyor and correspond to the feed port of the heating and compression assembly.

[0010] Preferably, the heating and compression assembly includes two opposing heating rollers and a housing, the housing being installed below the roller conveyor, and the two heating rollers being rotatably installed inside the housing; the feed inlet above the housing is correspondingly arranged with the film feeding mechanism; a first gear is coaxially mounted on the end of the rotating shaft of the heating roller, the two first gears meshing, and a second gear is mounted on the motor output shaft mounted on the housing, the second gear meshing with one of the first gears.

[0011] Preferably, a receiving tray is provided at the discharge port below the housing.

[0012] The beneficial effects of this invention are as follows: 1. In this invention, the box tray with packaging film is conveyed from left to right to the baffle and reaches the limit position, at which point it is exactly below the lifting platform, thus effectively positioning the box tray. Then, the first telescopic cylinder drives the lifting platform to move up and down, thereby driving the heating cutter, upper suction cup assembly, film feeding mechanism and other mechanisms to move up and down synchronously, thus realizing a rapid film tearing action.

[0013] 2. The second telescopic cylinder drives the corresponding heated cutter to approach the side wall of the box tray, thereby using the high-temperature heated cutter to cut the packaging film from the middle of the box tray, which can realize the rapid cutting operation of the packaging film and make the separation of the packaging film more efficient.

[0014] 3. When the lifting platform moves downward, the upper suction cup assembly moves downward with it and adsorbs the packaging film on the top of the box tray, while the packaging film at the bottom of the box tray is adsorbed by the lower suction cup assembly. After the heated cutter cuts the packaging film, the lifting platform drives the upper suction cup assembly to rise, thereby tearing the packaging film on the top of the box tray off the box tray.

[0015] 4. After the upper suction cup assembly tears open the cut upper packaging film, the lower packaging film is held in place by the lower suction cup assembly. At the same time, the third telescopic cylinder moves upward to lift the box tray body, thereby tearing the lower packaging film off the box tray. Then, the feeding mechanism set on one side of the film tearing platform pushes the box tray body to the discharge port on the side of the roller conveyor.

[0016] 5. When the fourth telescopic cylinder is activated, it drives the push plate to move horizontally backward through the connecting plate, so that the box tray on the roller conveyor can be smoothly sent to the feeding port and the film tearing operation of the packaging film below can be completed.

[0017] 6. After the packaging film is torn off the box tray, the fifth telescopic cylinder extends downwards to send the packaging film adsorbed on the upper and lower suction cup components through the roller gap to the heating and compression component for centralized processing, which makes it easier to collect and process the packaging film.

[0018] 7. The power of the motor is transmitted to the two first gears through the second gear, which in turn drives the two heating rollers to rotate in opposite directions. This heats and squeezes the packaging film from the film feeding mechanism, compressing the packaging film into sheets and collecting them in the receiving tray, which makes it easier for the subsequent recycling of the packaging film.

Detailed Implementation

[0020] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of the invention.

[0021] like Figure 1-4 As shown, this invention proposes a film-opening device for box tray packaging film, including a film-tearing platform. The film-tearing platform includes a horizontally arranged roller conveyor 1. A lifting platform is installed above the right-side conveying 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 point it is exactly below the lifting platform, thereby effectively positioning the box tray.

[0022] The lifting platform includes a support frame 22, a lifting plate 21, and a first telescopic cylinder 23. The support frame 22 is installed on both sides of the roller conveyor 1. The lifting plate 21 is horizontally positioned and slides up and down on the support frame 22. The first telescopic cylinder 23 is vertically installed on the support frame 22, and its piston rod is fixedly connected to the lifting plate 21. The first telescopic cylinder 23 drives the lifting plate 21 to move up and down, 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, thus realizing a rapid film tearing action.

[0023] Four heated cutting blades 3 are provided on the four sides of the box tray below the lifting plate 21. These four heated cutting blades 3 are connected to a horizontal drive assembly installed on the lifting platform. The heated cutting blades 3 adopt the existing electric heating cutting blade structure. The horizontal drive assembly includes four second telescopic cylinders 31, all horizontally installed below the lifting plate 21. The piston rod of each second telescopic cylinder 31 is fixedly connected to the corresponding heated cutting blade 3. By driving the corresponding heated cutting blade 3 closer to the side wall of the box tray through the second telescopic cylinder 31, the high-temperature heated cutting blade 3 cuts the packaging film from the middle of the box tray, enabling rapid film cutting and making the film separation more efficient.

[0024] The bottom of the lifting plate 21 is equipped with an upper suction cup assembly 71, and a lower suction cup assembly 72 is correspondingly provided above the film-tearing platform. The multiple suction cups in both suction cup assemblies are connected to an external negative pressure source. The lower suction cup assembly 72 and the top support mechanism are both located below the roller gap of the roller conveyor 1. When the lifting platform moves downward, the upper suction cup assembly 71 moves downward with it and adsorbs the packaging film on the top of the box tray, while the packaging film at the bottom of the box tray is adsorbed by the lower suction cup assembly 72. When the heated cutter 3 cuts the packaging film, the lifting platform drives the upper suction cup assembly 71 to rise, thereby tearing the packaging film on the top of the box tray off the box tray.

[0025] Below the film-tearing platform is a support mechanism for lifting the box tray upwards. This support mechanism includes a third telescopic cylinder 8, which is vertically mounted below the roller gap of the roller conveyor 1. When the upper suction cup assembly 71 tears open the cut upper packaging film, the lower packaging film is held by the lower suction cup assembly 72. Simultaneously, the upward movement of the third telescopic cylinder lifts the box tray body, thus tearing the lower packaging film off the box tray. A material-feeding mechanism on one side of the film-tearing platform then pushes the box tray body to the discharge port 10 on the side of the roller conveyor 1.

[0026] A feeding conveyor 12 is located at the feeding port 10 on the opposite side of the film-tearing platform from the feeding mechanism. The box tray with the packaging film torn off is pushed onto the feeding conveyor 12 via the feeding mechanism through the feeding port 10, and then transported to the next process via the feeding conveyor 12. The feeding mechanism includes a fourth telescopic cylinder 43 and a push plate 41. The push plate 41 is positioned horizontally on the side of the box tray opposite the feeding port 10. The fourth telescopic cylinder 43 is horizontally mounted below the roller conveyor 1, perpendicular to the push plate 41. The push plate 41 is fixed to the piston rod of the fourth telescopic cylinder 43 via a connecting plate 42 that passes through the gap between the rollers. When the fourth telescopic cylinder 43 actuates, it drives the push plate 41 to move horizontally backward via the connecting plate 42, thereby smoothly conveying the box tray on the roller conveyor 1 to the feeding port 10 and completing the film-tearing operation below.

[0027] A film feeding mechanism is also vertically installed on the lifting platform. This mechanism delivers the torn packaging film to the heating and compression assembly located below the film-tearing platform. The film feeding mechanism includes a fifth telescopic cylinder 5 mounted vertically downwards on the lifting platform. The piston rod of the fifth telescopic cylinder 5 passes through the gap between the rollers of the roller conveyor 1 and corresponds to the inlet of the heating roller 60 assembly. After the packaging film is torn from the box tray, the downward extension of the fifth telescopic cylinder 5 allows the packaging film adsorbed on the upper suction cup assembly 71 and the lower suction cup assembly 72 to be delivered through the roller gap to the heating roller 60 assembly for centralized processing, facilitating the collection and handling of the packaging film.

[0028] The heating and compression assembly is used to heat and compress the torn packaging film into sheets. The assembly includes two opposing rotating heating rollers 60 and a housing 6. The housing 6 is mounted below the roller conveyor 1, and the two heating rollers 60 are rotatably mounted inside the housing 6. The two heating rollers 60 employ the existing electric heating roller structure. The feed inlet above the housing 6 corresponds to the film feeding mechanism. Second gears 6362 are coaxially mounted on the ends of the rotating shafts of the two heating rollers 60, and the two second gears 6362 mesh. A second gear is mounted on the output shaft of the motor mounted on the housing 6, and this second gear meshes with one of the second gears 6362. A receiving tray 61 is provided at the discharge port below the housing 6. The motor's power is transmitted to the two second gears 6362 through the second gears, thereby driving the two heating rollers 60 to rotate in opposite directions. This heats and compresses the packaging film from the film feeding mechanism, compressing it into sheets and collecting them in the receiving tray 61, facilitating subsequent recycling of the packaging film.

[0029] When using this invention, the box tray is conveyed by the roller conveyor 1 to the limit position of the baffle 11. Then, the first telescopic cylinder 23 drives the lifting plate 21 to descend. Afterward, the second telescopic cylinder 31 drives the heating cutter 3 to adhere to the outer packaging film of the box tray. The heating cutter 3 cuts the packaging film through high temperature. Two suction cup assemblies located at the top and bottom of the box tray use negative pressure to attract the broken packaging film. The first telescopic cylinder 23 drives the lifting plate 21 to rise, separating the broken packaging film above the box tray from the box tray. The third telescopic cylinder located below the box tray lifts the box tray. The packaging film, which is disconnected from the box tray, is completely detached from the box tray. The fourth telescopic cylinder 43 moves the push plate 41 horizontally, sending 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, sending the packaging film adsorbed on the two suction cup assemblies through the gap between the rollers to the heating roller 60 assembly. The two heating rollers 60 rotate in opposite directions, heating and squeezing the packaging film from the film feeding mechanism. The packaging film is compressed into a sheet and collected in the receiving tray 61, thus completing the box tray film removal process.
