Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to an integrated wheel assembly, in particular to a new integrated wheel assembly for a cigarette making machine. Background Art

[0002] During routine production, tobacco factories reported a high rate of fines trapped at the filter end of their cigarettes. These fines also exhibited wrinkling, air leakage, and other issues after splicing. This resulted in high scrap rates, high auxiliary material consumption, and significantly reduced product quality consistency. Furthermore, incomplete rejection of substandard cigarettes during the filter removal process led to consumer complaints. Analysis of the docking and installation process and on-site observations of the unit revealed that 70% of fines trapped incidents were caused by inertial fines ejection from the integrated wheel.

[0003] Traditional integrated wheels consist of a wheel body with a smoke receiving groove and a pin groove on its surface, each with an air intake hole. During actual use, the pin groove is easily contaminated with glue and cigarette dust, which can be carried into the cigarette holder, requiring machine downtime for cleaning. Frequent downtime for cleaning reduces efficiency and affects production.

[0004] For example, a Chinese patent document discloses an improved integrated wheel structure for the PROTOS series cigarette making machine (Application No. 200920190462.9). This wheel includes an integrated wheel body without needle plates, and instead features trapezoidal grooves spaced along its circumference. By eliminating 32 needle plates, the improved wheel body avoids contact with glue during use, thus eliminating glue accumulation. Tip rods and rotten cigarettes that fall onto the wheel body are immediately carried away, preventing machine downtime caused by cigarette squeezing. However, the negative pressure holes in this integrated wheel are straight, resulting in less than ideal suction, and the lack of a filter cartridge makes it prone to clogging, shortening its service life. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems in the existing technology and to provide a new integrated wheel assembly for a cigarette making machine which has good dust collection effect and is not prone to clogging.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a new integrated wheel assembly of a cigarette making machine, comprising a wheel body and a cover body fixedly connected to one end of the wheel body, the outer wall of the wheel body is evenly provided with a cigarette placing groove, the cigarette placing groove extends parallel to the axis of the wheel body, and is characterized in that the outer walls of the pair of wheel bodies are ring-shaped and the annular grooves separate the cigarette placing grooves, the annular grooves are provided with a mounting cavity in the middle of the wheel body, a dust collecting barrel is provided in the mounting cavity, the inner end of the cover body is pressed against the inner end of the dust collecting barrel, negative pressure holes are evenly distributed on the wheel body, and the outer ends of the negative pressure holes are connected to the cigarette placing grooves, and the outer end diameter of the negative pressure hole is smaller than the inner end diameter.

[0007] During operation, impurities adhering to the outer wall of the cigarette in the cigarette slot are adsorbed through the negative pressure hole and adsorbed into the dust collecting tube, which has the advantage of good dust collection effect. By opening the cover, the dust collecting tube can be cleaned, which is convenient for dust removal, not easy to be blocked, and increases the service life. The outer end diameter of the negative pressure hole is smaller than the inner end diameter, which increases the suction force of the negative pressure hole, thereby improving the dust collection effect.

[0008] In the novel integrated wheel assembly of the cigarette making machine, the inner side wall of the negative pressure hole is a conical surface. This arrangement has the advantage of a strong suction force.

[0009] In the novel integrated wheel assembly of the cigarette making machine, the negative pressure hole is trumpet-shaped and the cross section of the inner side wall of the negative pressure hole is arc-shaped. This arrangement improves the suction force of the negative pressure hole and has a longer service life.

[0010] In the novel integrated wheel assembly for a cigarette making machine, a bearing is sleeved on the outer end of the cover, and a shoulder is provided on the cover against which the inner ring of the bearing abuts. The bearing facilitates rotation of the wheel, providing advantages of easy installation and reliable use.

[0011] In the novel integrated wheel assembly of the cigarette making machine, the other end of the wheel body is threadedly connected to the front cover body, and the inner end of the front cover body abuts against the outer end of the dust collecting barrel. The provision of the front cover body facilitates the replacement of the dust collecting barrel and has the advantages of being convenient and reliable.

[0012] In the novel integrated wheel assembly for a cigarette making machine, an annular groove is formed on the outer wall of the front cover. A sealing ring is embedded in the groove and squeezed between the front cover and the wheel. The sealing ring improves the sealing effect between the front cover and the wheel, preventing air leakage.

[0013] In the novel integrated wheel assembly of the cigarette making machine, the outer side wall of the wheel body is provided with two annular grooves which are coaxially arranged with the wheel body and both pass through the cigarette receiving slot.

[0014] Compared with the existing technology, the new integrated wheel assembly of the cigarette making machine has the following advantages:

[0015] 1. Impurities adhering to the outer wall of the cigarette in the cigarette slot are adsorbed through the negative pressure hole and adsorbed into the dust collection tube, which has the advantages of good dust collection effect and is not easy to be blocked;

[0016] 2. The dust collection tube can be cleaned by opening the cover, which is convenient for dust removal and prolongs the service life;

[0017] 3. The inner wall of the negative pressure hole is a conical surface, which has the advantage of strong suction;

[0018] 4. By providing the above-mentioned sealing ring, the sealing effect between the front cover body and the wheel body is improved, and air leakage is avoided. BRIEF DESCRIPTION OF THE DRAWINGS
