[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 2 - Figure 4 , the utility model provides an embodiment: 1. A packaging film ink printing device comprises a box body 1, an ink box 2 is fixedly connected to the front side of the top of the box body 1, a feeding pipe 3 is fixedly connected to the middle side of the top of the ink box 2, a connecting pipe 4 is fixedly connected to the middle side of the lower part of the ink box 2, a printing template 5 is fixedly connected to the bottom of the connecting pipe 4, a cylinder 6 is fixedly connected to the inner bottom wall of the box body 1, a lower pressing die 7 is fixedly connected to the output end of the cylinder 6, two guide rollers 8 are rotatably connected to the rear side of the inner wall of the box body 1, a plurality of rollers 9 are rotatably connected to the rear side of the inner wall of the box body 1, two drying devices 10 are arranged on the rear side of the inner wall of the box body 1, two electric heating nets 11 are fixedly connected to the rear side of the inner wall of the box body 1, and a printing template 5 is fixedly connected to the bottom of the connecting pipe 4. A filter box 12 is connected, one side of the filter box 12 is fixedly connected to an air outlet pipe 13, the outside of the filter box 12 is fixedly connected to a suction pipe 14, the lower side of the inside of the filter box 12 is fixedly connected to a suction fan 21, the upper side of the inside of the filter box 12 is slidably connected to an activated carbon filter screen 22, the outside of the filter box 12 is fixedly connected to two thin shells 1 25, the top of the thin shell 1 25 is fixedly connected to a thin shell 26, the inside of the thin shell 1 25 is slidably connected to a plug rod 24, one side of the outside of the plug rod 24 is fixedly connected to a baffle 28, the other side of the outside of the plug rod 24 is sleeved with a spring 23, and a blocking block 27 is arranged on the top of the baffle 28, and a cleaning component is arranged on the front side of the inside of the box body 1, and the cleaning component is used to clean dust on the packaging film

[0033] Specifically, during operation, first, the packaging film needs to pass through the film introduction channel in the box body 1, and then it is wound around multiple rollers 9 and guide rollers 8. During this period, the cleaning component is responsible for cleaning the dust on the surface of the film. Then, the two cylinders 6 are started synchronously to drive the lower die 7 to rise, so that it cooperates with the printing template 5 to accurately print the film. After printing, the film is sent to the right chamber, and then the two drying devices 10 start to operate to dry the film wound on the rollers 9 and guide rollers 8. The exhaust gas generated is driven by the suction fan 21 in the box body 1, filtered through the activated carbon filter 22, and discharged to the exhaust pipe 13. When replacing the activated carbon filter 22, by pulling the plug rod 24, the baffle 28 will move outward under the action of the spring 23, and the blocking block 27 will slide into the thin shell 25 to maintain stability. This design avoids accidental resetting caused by the elastic force of the spring 23 when the filter is replaced. When installing the filter, just push up the blocking block 27, and under the action of the spring 23, the baffle 28 and the plug-in rod 24 will automatically return to their positions, ensuring that the filter is firmly embedded. The whole process is smooth and easy to operate.

[0034] Reference Figure 2 and Figure 5 The cleaning component includes a motor 15, one side of the motor 15 is fixedly connected to the front side of the inner wall of the box body 1, a turntable 16 is fixedly connected to the output end of the box body 1, a connecting rod 17 is fixedly connected to the top of the turntable 16, a hollow shell 18 is slidably connected to the outer side of the connecting rod 17, two U-shaped brushes 20 are fixedly connected to the outer side of the hollow shell 18, and a limiting block 19 is fixedly connected to the outer side of the U-shaped brush 20.

[0035] Specifically, at this moment, the drive motor 15 drives the turntable 16 to rotate, which acts on the turntable 16 to start rotating. This rotation then causes the connecting rod 17 to rotate and slide along the inside of the hollow shell 18. This sliding process directly drives the U-shaped brush 20, and under the constraint of the limit block 19, it achieves flexible movement, thereby achieving efficient cleaning of dust on the packaging film.

[0036] Reference Figure 2 and Figure 4 The upper outer part of the connecting pipe 4 is fixedly connected to the front side of the box body 1, the outer side of the suction pipe 14 is fixedly connected to the inside of the box body 1, one end of the spring 23 is fixedly connected to the middle of the baffle 28, and the other end of the spring 23 is fixedly connected to the inner wall of the thin shell 1 25. The plug-in rod 24 penetrates the filter box 12 and is plugged into the activated carbon filter 22. The upper side of the blocking block 27 is slidably connected to the inside of the thin shell 26, and the lower side of the blocking block 27 is slidably connected to the inside of the thin shell 1 25. One side of the thin shell 26 is fixedly connected to the outside of the filter box 12, the outer side of the baffle 28 is slidably connected to the inside of the thin shell 1 25, and the outer side of the limit block 19 is slidably connected to the inner wall of the box body 1.

[0037] Specifically, the upper outer portion of the connecting pipe 4 is fixed inside the front side of the housing 1, ensuring the flow path of air or liquid. The suction pipe 14 is fixed inside the housing for gas to enter the filter box 12. The spring 23 is a key component, one end of which is fixed in the center of the baffle 28, playing a role of balance and control, and the other end is embedded in the inner wall of the thin shell 1 25, ensuring the stability of the spring 23 and the appropriate tension on other components. The plug-in rod 24 passes through the filter box 12 and penetrates into the inside of the activated carbon filter 22, providing a flexible interface for the installation and replacement of the filter. The blocking block 27 is designed to slide in the thin shell 26 at the top and be connected to the thin shell 1 25 at the bottom to ensure its stability and positioning during operation. One side of the thin shell 26 is fastened to the outside of the filter box 12 to provide additional support and structural integrity. The outer side of the baffle 28 is connected to the thin shell 1 25 by sliding, playing a supporting and regulating role. The limiting block 19 limits the movement track of the U-shaped brush 20, thereby ensuring the normal working range of the system.

[0038] Working principle: When it is working, firstly, the packaging film to be printed is passed through the film channel of the box body 1, and at the same time, the packaging film is wrapped around multiple rollers 9 and two guide rollers 8. At this time, the driving motor 15 drives the turntable 16 to rotate, and then drives the turntable 16 to rotate, so that the connecting rod 17 rotates, and then drives the connecting rod 17 to slide inside the hollow shell 18, and then drives the U-shaped brush 20 to move back and forth under the restriction of the limit block 19, so as to clean the dust of the packaging film, and synchronously start the two cylinders 6, the two cylinders 6 drive, and then drive the lower die 7 The lower die 7 cooperates with the printing template 5 to print the packaging film, and then the plurality of rollers 9 are started to allow the packaging film at the printed portion to enter the right chamber, and the two drying devices 10 are started to dry the packaging film wrapped around the plurality of rollers 9 and the two guide rollers 8. The generated harmful gas is driven by the suction fan 21 inside the filter box 12 to suck the generated gas from the inside of the box body 1 into the filter box 12, and is filtered through the activated carbon filter 22 and goes out from the outlet pipe 13. When the activated carbon filter 22 needs to be removed, the plug rod 24 is pulled. This action will drive the baffle 28 to move outward, and at the same time the spring 23 will be compressed, and the blocking block 27 will slide from the inside of the thin shell 26 into the thin shell 1 25. This design prevents the baffle 28 and the plug-in rod 24 from re-entering the activated carbon filter 22 under the elastic force of the spring 23 after the hand is released. At this time, take away the activated carbon filter 22. When the activated carbon filter 22 needs to be installed, just pull the blocking block 27 upward. At this time, under the elastic force of the spring 23, the baffle 28 and the plug-in rod 24 will move inward until they are firmly inserted into the filter box 12 and connected to the inside of the activated carbon filter 22. At this time, the installation is completed.
