Description

A roller arm mechanism and filter tip assembly machine Technical Field

[0001] This utility model relates to the field of cigarette machinery technology, and in particular to a roller arm mechanism and a filter tip assembly machine. Background Technology

[0002] In cigarette production, processes such as cutting tipping paper and making double-strand cigarettes are required. During operation, the tipping paper is glued by an adhesive applicator and then cut into tipping paper pieces that meet process requirements by a cutting drum and a cutting knife. The filter tipping machine places three cigarette sections (single cigarette - double filter - single cigarette) into the cigarette receiving groove of the converging drum. A length adjustment device brings the three sections closer together, and then the tipping paper is pasted onto the sections to form a double-strand cigarette. The length adjustment device includes two roller arms and two floats. The two roller arms are located on either side of the converging drum, with rollers mounted on them. The floats are located between the rollers and the converging drum. During adjustment, the two roller arms are moved closer or further apart, causing the rollers to abut against the floats, which in turn brings the three cigarette sections closer together.

[0003] During production, the high-speed rotation of the paper cutter throws adhesive residue onto the rollers of the roller arm. Additionally, adhesive overflows during the splicing of paper sheets and the assembly of the three-section cigarette assembly; this overflow is also thrown onto the rollers due to the rotation of the converging drum. As the floats and rollers rotate at high speed, the adhesive residue is compressed and adheres to the rollers, altering the center distance between the two rollers, creating eccentricity, and consequently changing the distance between the two floats. This results in deviations in cigarette length, affecting product quality. Due to the difference in operation between the inner and outer rollers, the outer rollers offer more space and a wider field of vision, making them easier to clean. However, the inner rollers are obstructed by the wiring and air pipes of the drums, making operation difficult, visibility limited, and cleaning challenging. Even with tools, cleaning is not thorough.

[0004] Therefore, there is an urgent need for a roller arm mechanism and a filter nozzle assembly machine to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a roller arm mechanism and filter nozzle assembly machine that is easy to clean and maintain, cleans thoroughly, can quickly and timely remove accumulated glue, keeps the working surface of the roller clean, eliminates the influence of cigarette length deviation caused by accumulated glue on the roller, and has low manufacturing cost and stable operation.

[0032] As shown in Figure 1, this utility model provides a roller arm mechanism applicable to the ZJ116 winding and splicing machine. It includes an arm body 1, a roller 2, a scraping assembly 4, and an air blowing assembly 5. The roller 2 is rotatably connected to the arm body 1, specifically, the roller 2 is connected to the arm body 1 via a roller shaft 3. The scraping assembly 4 includes a scraper 41, which is disposed on the arm body 1 and used to scrape away adhesive residue from the outer periphery of the roller 2. The air blowing assembly 5 includes an air pipe 51, which is disposed on the arm body 1 and used to blow air onto the outer periphery of the roller 2 to remove residual adhesive residue. By using the scraper 41, adhesive residue is scraped away from the outer periphery of the roller 2 as it rotates. By using the air pipe 51, residual adhesive residue scraped by the scraper 41 is blown away from the outer periphery of the roller 2. The scraper 41 and air pipe 51 work together to clean the glue residue on the roller 2. Cleaning and maintenance are convenient and thorough, quickly removing accumulated glue and keeping the working surface of the roller 2 clean. This ensures the distance between the roller 2 and the float ring remains constant, keeping the distance between the two float rings within the range of cigarette length production. This eliminates the impact of glue buildup on the roller 2 on cigarette length deviation. Furthermore, the roller arm mechanism has low manufacturing cost and stable operation. In addition, the scraper 41 and air pipe 51 are mounted on the arm body 1, resulting in a compact structure that saves space. The small installation space does not affect the installation of other operating components, and it improves the integration level of the filter nozzle assembly machine.

[0033] Optionally, in this embodiment, the scraping assembly 4 further includes a fixing base 42, which is detachably connected to the arm body 1, and the scraper 41 is disposed on the fixing base 42. The scraper 41 is fixed to the arm body 1 by the fixing base 42, which facilitates the fixing of the scraper 41. The fixing base 42 is detachably connected to the arm body 1, which facilitates the disassembly of the scraping assembly 4. In other embodiments, the scraper 41 can also be directly fixed to the arm body 1, and the fixing method can be snap-fit ​​or welding, etc.

[0034] Specifically, in this embodiment, the scraping assembly 4 further includes a first screw 43 and a second screw 44. The arm body 1 has a first internal threaded hole. The first screw 43 passes through the fixing seat 42 and is threadedly connected to the first internal threaded hole. The fixing seat 42 has a second internal threaded hole. The second screw 44 passes through the scraper 41 and is threadedly connected to the second internal threaded hole. This arrangement facilitates the disassembly of the fixing seat 42 and the scraper 41, and ensures a stable and reliable connection. Furthermore, the first screw 43 is an M6 locking screw, and the second screw 44 is an M4 locking screw.

[0035] Optionally, the mounting base 42 is provided with a groove extending along the length of the mounting base 42. The scraper 41 is slidably connected to the groove. The bottom wall of the groove is provided with a plurality of second internal threaded holes spaced apart along the length of the mounting base 42. A second screw 44 passes through the scraper 41 and is threadedly connected to one of the second internal threaded holes. This configuration allows the position of the scraper 41 relative to the roller 2 to be adjustable, providing a certain amount of installation space to facilitate adjustment of the scraper 41's installation position, ensuring the scraper 41 is in the optimal position relative to the roller 2. Furthermore, the slidable connection between the scraper 41 and the groove guides and positions the scraper 41 during position adjustments.

[0036] Optionally, the scraper 41 is disposed on the side wall of the fixing base 42 and is perpendicular to the arm body 1. This facilitates the installation of the scraper 41 and provides a better scraping effect on the adhesive residue on the roller 2.

[0037] Optionally, in this embodiment, the air blowing assembly 5 further includes a strapping strap 52, through which the air tube 51 is fixed to the arm body 1. This arrangement simplifies the fixing of the air tube 51 and facilitates installation. In other embodiments, the air tube 51 can also be glued to the arm body 1. Further, the arm body 1 is provided with an annular locking groove, into which the strapping strap 52 engages, pressing the air tube 51 against the arm body 1. By engaging the strapping strap 52 within the annular locking groove, the strapping strap 52 serves a positioning function, making the fixing of the air tube 51 more reliable.

[0038] While the scraper 41 removes the glue residue on the outer periphery of the roller 2, a small amount of glue residue will also accumulate on the scraper 41 over time, reducing the scraping efficiency of the scraper 41. Optionally, in this embodiment, the air outlet of the air pipe 51 is directed towards the outer periphery of the roller 2 and towards the cutting end of the scraper 41. This arrangement ensures that the residual glue residue on the outer periphery of the roller 2 is blown away, while also blowing away the glue residue on the cutting end of the scraper 41, thus providing a secondary guarantee for keeping the working surface of the roller 2 clean.

[0039] Optionally, in this embodiment, the distance from the air outlet of the air pipe 51 to the outer peripheral wall of the roller 2 along the length of the air pipe 51 is 10 mm, which can effectively blow away residual adhesive residue on the roller 2. In addition, the air pressure in the air passage is 30 mbar, which has a good effect on blowing away adhesive residue.

[0040] Optionally, in this embodiment, the distance from the cutting end of the scraper 41 to the outer peripheral wall of the roller 2 along the length of the scraper 41 is 0.05 mm, which satisfies the requirement that the scraper 41 cleans the roller 2 without damaging the roller 2.

Specifically, the arm body 1 is provided with a connecting hole 11, and the arm body 1 is connected to the moving block through the connecting hole 11. This filter tip assembly machine can clean the glue residue on the roller 2, and the cleaning and maintenance are convenient and thorough. It can quickly and timely remove the accumulated glue, keep the working surface of the roller 2 clean, and eliminate the influence of the glue accumulation on the roller 2 on the cigarette length deviation. In addition, this filter tip assembly machine has a high degree of integration. Optionally, the filter tip assembly machine also includes a screw, which is connected to the moving block for driving the moving block to move.
