Description

Technical Field

[0001] The utility model belongs to the field of film winding and unwinding mechanisms of fully automatic tray packaging machines, and specifically relates to an automatic film winding and unwinding mechanism for fully automatic tray packaging. Background Art

[0002] A fully automatic tray packaging machine is an efficient packaging device, mainly used for automatically loading products into trays or boxes, and performing operations such as sealing and labeling. It is widely used in industries such as food, medicine, electronics, and cosmetics, which can improve production efficiency, reduce labor costs, and ensure the consistency and stability of packaging quality. The film winding and unwinding mechanism is one of its key components, mainly responsible for the supply and recycling of the film. This mechanism plays a crucial role in the packaging process, ensuring that the film can be smoothly and accurately supplied to the packaging station to complete the packaging of the product;

[0003] When the packaging machine starts, the film on the film reel is pulled out by the traction device and conveyed to the packaging station through a series of guide rollers and tension control devices. At the packaging station, the film is heat-sealed and cut to form independent packaging bags. After the packaging is completed, the waste part of the film is recycled into the film winding mechanism for subsequent processing. One end of the traditional film winding and unwinding mechanism is a finished film unwinding mechanism, and the other end is a waste film winding mechanism. When the finished film is used up, a new film needs to be installed. At this time, the normal film changing time takes five minutes. Not only is the film changing time relatively long, but also manual replacement is required, thus reducing the automation efficiency of the automatic film winding and unwinding mechanism and further reducing the packaging efficiency.

[0004] In summary, the utility model provides an automatic film winding and unwinding mechanism for fully automatic tray packaging to solve the above problems. Summary of the Utility Model

[0018] Embodiment 1

[0019] As Figure 1As shown in the figure, this is the first embodiment of the present utility model. This embodiment provides an automatic film winding and unwinding mechanism for fully automatic tray packaging, which includes a frame. On one side of the upper end of the frame, a first film unwinding air shaft 1 is installed. On the other side of the upper end of the frame, a second film unwinding air shaft 5 is installed. On the surface of the frame and below the first film unwinding air shaft 1, a first detection roller 2, a first guide roller 3, and a first microswitch 26 are installed. On the surface of the frame and below the second film unwinding air shaft 5, a second detection roller 6, a second film guiding roller 7, and a second microswitch 27 are installed. On one side of the lower end of the frame, a first film changing driving roller 4, a film changing cylinder 8, and a third film guiding roller 10 are installed. The output end of the film changing cylinder 8 is installed with a second film changing driving roller 9. On the other side of the lower end of the frame, a film winding air shaft 25 is installed. The first detection roller 2 and the second detection roller 6 are used to detect the usage of the film. The first film changing driving roller 4, the second film guiding roller 7, the film changing cylinder 8, the second film changing driving roller 9, the first microswitch 26, and the second microswitch 27 are used for automatic film changing.

[0020] As Figure 1 shown, the wound film is installed on the surface of the first film unwinding air shaft 1. One end of the wound film successively bypasses the first detection roller 2, the first guide roller 3, the first film changing driving roller 4, the third film guiding roller 10, the fourth film guiding roller 11, and the fifth film guiding roller 12. After passing through the photoelectric switch 13, it successively bypasses the sixth film guiding roller 14, the seventh film guiding roller 15, the adjusting roller 16, the eighth film guiding roller 17, and the ninth film guiding roller 18. It is frictionally driven by the tight fit of the passive shaft 19 and the driving shaft 20. After passing through the frame, it bypasses the tenth film guiding roller 21, the eleventh film guiding roller 22, the gravity shaft 23, and the twelfth film guiding roller 24, and is wound by the film winding air shaft 25. The spare wound film is installed on the surface of the second film unwinding air shaft 5. After bypassing the second detection roller 6 and the second film guiding roller 7, it is fixed on the surface of the second film changing driving roller 9 and has an adhesive sticker on its surface. When the wound film on the surface of the first film unwinding air shaft 1 is used up, the first microswitch 26 detects and sends a signal to control the film changing cylinder 8 to push the second film changing driving roller 9 to make it stick to the first film changing driving roller 4, thereby sticking the spare wound film fixed on the second film changing driving roller 9 to the film being used, making it replace the used-up film, so as to achieve the effect of automatic and fast film changing without stopping the equipment.

[0021] Embodiment 2

[0022] Referring to the figure, this is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0023] In this embodiment, on the other side of the lower end of the frame, a tenth film guiding roller 21, an eleventh film guiding roller 22, a gravity shaft 23, and a twelfth film guiding roller 24 are also installed. The tenth film guiding roller 21, the eleventh film guiding roller 22, the gravity shaft 23, and the twelfth film guiding roller 24 are all movably connected to the frame through bearings.

[0024] At the center of the lower end of the frame, a fourth film guiding roller 11, a fifth film guiding roller 12, a photoelectric switch 13, a sixth film guiding roller 14, a seventh film guiding roller 15, an adjusting roller 16, an eighth film guiding roller 17, a ninth film guiding roller 18, a passive shaft 19 and an active shaft 20 are installed.

[0025] The first guiding roller 3, the second film guiding roller 7, the third film guiding roller 10, the fourth film guiding roller 11, the fifth film guiding roller 12, the sixth film guiding roller 14, the seventh film guiding roller 15, the eighth film guiding roller 17, the ninth film guiding roller 18, the tenth film guiding roller 21, the eleventh film guiding roller 22 and the twelfth film guiding roller 24 are all used for film guiding. The photoelectric switch 13 is used to detect the moving position of the film.

[0026] The first film paying-off air shaft 1, the second film paying-off air shaft 5, the first detecting roller 2, the second detecting roller 6, the first guiding roller 3 and the second film guiding roller 7 are all movably connected to the frame through bearings. The film changing cylinder 8 is fixedly connected to the frame. The second film changing driving roller 9 is movably connected to the output end of the film changing cylinder 8 through a bearing.

[0027] The third film guiding roller 10 and the first film changing driving roller 4 are both movably connected to the frame through bearings. The first micro switch 26 and the second micro switch 27 are both fixedly connected to the frame.

[0028] As shown in the figure, the movement track of the winding film can be limited by the third film guiding roller 10, so as to prevent the winding film from deviating during the unwinding process. The movement track of the winding film can be corrected by the adjusting roller 16 and the gravity shaft 23, so as to achieve the effect of deviation correction. The third film guiding roller 10, the fourth film guiding roller 11, the fifth film guiding roller 12, the sixth film guiding roller 14, the seventh film guiding roller 15, the eighth film guiding roller 17, the ninth film guiding roller 18, the tenth film guiding roller 21, the eleventh film guiding roller 22 and the twelfth film guiding roller 24 are used to guide and support the winding film, so that it can be stably wound.

[0029] During use, the winding film is installed on the surface of the first film paying-off air shaft 1. One end of the winding film sequentially bypasses the first detecting roller 2, the first guiding roller 3, the first film changing driving roller 4, the third film guiding roller 10, the fourth film guiding roller 11 and the fifth film guiding roller 12, passes through the photoelectric switch 13, and then sequentially bypasses the sixth film guiding roller 14, the seventh film guiding roller 15, the adjusting roller 16, the eighth film guiding roller 17 and the ninth film guiding roller 18. It is frictionally driven by the tight fit of the passive shaft 19 and the active shaft 20.

[0030] The spare roll film is installed on the surface of the second film-releasing air shaft 5. After passing around the second detection roller 6 and the second film-guiding roller 7, it is fixed on the surface of the second film-changing driving roller 9 and has self-adhesive on its surface. When the roll film on the surface of the first film-releasing air shaft 1 is used up, the first micro-switch 26 detects and sends a signal to control the film-changing cylinder 8 to push the second film-changing driving roller 9 to make it stick to the first film-changing driving roller 4, thereby sticking the spare roll film fixed on the second film-changing driving roller 9 to the roll film in use to make it replace the used-up roll film, so as to achieve the effect of automatic and quick film-changing without stopping the equipment. Similarly, when the roll film on the surface of the second film-releasing air shaft 5 is used up, the spare roll film installed on the surface of the first film-releasing air shaft 1 can also be automatically changed through the signal detected and sent by the second micro-switch 27.
