[0002] During the distribution of cigarettes, the cigarette cartons required by each merchant need to be packaged so that the drivers can deliver them quickly. During the packaging process, a baler is needed to increase the packaging efficiency. However, the braking function of the film-applying device in the existing baler is unstable, so that after the film is delivered to the previous household, the film-applying roller still has a certain inertia and will continue to rotate for a distance. This will cause the packaging film to relax in the film-applying device, resulting in unstable film quality. The packaged products often do not meet the quality specifications. At this time, the machine will need to be stopped and the film will be re-threaded for tightening, resulting in a continuous lack of production efficiency and a high failure rate. At the same time, the packaging film is seriously wasted, resulting in increased production costs. Utility Model Content

DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0018] See also Figure 1-2 As shown, a film feeding device of a cigarette strip baling machine of the utility model comprises two mounting plates 1 connected to a baling machine frame, a first film upper roller 4 for supporting a packaging film roller 6 is rotatably connected to the two mounting plates 1, a second film upper roller 5 is rotatably connected to the mounting plate 1 at both ends on one side of the first film upper roller 4, a distance between the first film upper roller 4 and the second film upper roller 5 is smaller than the diameter of the packaging film roller 6, a tensioning roller 7 for tensioning the packaging film is provided on one side of the second film upper roller 5, limiting wheels 8 are provided on both sides of the first film upper roller 4, brake assemblies 2 for stopping the first film upper roller 4 are provided on both sides below the first film upper roller 4, a dust removal device 3 for scraping dust on the rubber roller is provided on one side of the second film upper roller 5, the height of the support block 22 is adjusted by rotating the screw 23, so that the rubber block 21 installed thereon contacts with the first film upper roller 4, and when film is applied, the packaging film on the packaging film roller 6 is tightened by the tensioning roller 7 The packaging film is pulled by the front, so that the packaging film roller 6 rotates, and at the same time, the first upper film roller 4 and the second upper film roller 5 are driven to rotate. When the front stops pulling the film, the first upper film roller 4 receives the friction force of the rubber block 21 and stops rotating immediately, so as to prevent the first upper film roller 4 from continuing to rotate due to inertia, thereby effectively preventing the packaging film on the packaging film roller 6 from continuing to rotate out and preventing the packaging film from loosening. When the next household is packaging, the packaging film is still in a taut state, which effectively improves the packaging quality. Since the second upper film roller 5 has a sliding contact with the packaging film, static electricity is generated on the second upper film roller, so that the second upper film roller 5 will absorb dust in the air, thereby adhering to the packaging film, affecting the packaging quality. The scraper 33 of the dust removal device 3 can effectively scrape off the dust on the second upper film roller 5, thereby playing a dust removal role and improving the packaging quality in the later stage.

[0019] Specifically, the brake assembly 2 includes a support rod 24, a mounting block 25, a screw 23, a support block 22 and a rubber block 21. One end of the support rod 24 is vertically connected to the mounting plate 1, and the other end of the support rod 24 is connected to the mounting block 25. One end of the screw 23 is threadedly connected to the mounting block 25, and the other end of the screw 23 is rotatably connected to the support block 22. The rubber block 21 is installed on the support block 22, and the upper end of the rubber block 21 is in contact with the first upper film roller 4. The height of the support block 22 is adjusted by rotating the screw 23 so that the rubber block 21 installed thereon is in contact with the first upper film roller 4, thereby braking the first upper film roller 4.

[0020] Preferably, the upper end surface of the rubber block 21 is in an arc-shaped structure, and the arc-shaped surface of the rubber block 21 is matched with the first upper film roller 4, so that the contact area between the rubber block 21 and the first upper film roller 4 is larger and the braking performance is better.

[0021] Furthermore, a guide rod 26 is provided below the support block 22 , and the guide rod is movably plugged into the mounting block 25 , and the guide rod 26 plays a guiding role.

[0022] Furthermore, the dust removal device 3 includes a scraper 33, a spring 32 and a rotating shaft 31. Both sides of the scraper 33 are rotatably connected to the mounting plate 1 through the rotating shaft 31. One end of the spring 32 is connected to the scraper 33, and the other end is connected to the mounting plate 1. One side of the scraper 33 is in contact with the second upper film roller 5. Under the action of the spring 32, the scraper 33 always keeps pressing the second upper film roller 5, effectively scraping off the dust adsorbed on the second upper film roller 5, thereby ensuring that no dust is deposited between the second upper film roller 5 and the packaging film, thereby affecting the packaging quality.

[0023] Furthermore, the distance between the two limiting wheels 8 is equal to the length of the packaging film roller 6. The limiting wheels 8 are made of silicone material. The limiting wheels 8 limit the packaging film roller 6 and can also increase the friction on both sides of the packaging film roller 6 to assist the packaging film roller 6 in braking and stopping.

[0024] Furthermore, the rubber block 21 has a U-shaped structure, so that the rubber block 21 has a certain elastic force, so that the rubber block 21 can better fit with the first upper film roller 4. A binding belt 9 is provided at the open end of the rubber block 21 to prevent the rubber block 21 from having too much elastic force and pressing the first upper film roller 4 too tightly.

[0025] When the film feeding device of a cigarette strip packaging machine of the present embodiment is in use, the height of the support block 22 is adjusted by rotating the screw 23, so that the rubber block 21 installed thereon contacts the first film-applying roller 4. When film is applied, the packaging film on the packaging film roller 6 is tightened by the tensioning roller 7. The packaging film is pulled by the front, so that the packaging film roller 6 rotates, and the first film-applying roller 4 and the second film-applying roller 5 are also driven to rotate. When the front stops pulling the film, the first film-applying roller 4 receives the friction force of the rubber block 21, and can stop rotating immediately, so as to prevent the first film-applying roller 4 from continuing to rotate due to inertia. The second upper film roller 5 is in sliding contact with the packaging film, so that static electricity is generated on the second upper film roller 5, and dust in the air is adsorbed on the second upper film roller 5, which adheres to the packaging film and affects the packaging quality. The dust on the second upper film roller 5 is effectively scraped off by the scraper 33 of the dust removal device 3, which plays a dust removal role, improves the packaging quality in the later stage, and reduces the occurrence of faults. The film feeding device of the cigarette strip baling machine of the utility model reduces the occurrence of faults while ensuring the quality of the upper film, and has the characteristics of wide application range and strong practicality.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
