Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a device for removing outer packaging paper tubes of defective cigarettes. Background Art

[0002] During the production process of filter cigarettes, factors such as raw materials, equipment, and the quality of operators may cause problems such as insufficient fullness and tightness of tobacco, blurred or missing work number printing, color difference of tipping paper, air leakage at the interface, inconsistent draw resistance, and packaging quality defects, resulting in a certain number of defective cigarettes. These defective cigarettes are not caused by tobacco quality problems, so the tobacco can be completely recycled. In the existing technology, there are two main methods for recycling tobacco from cigarettes. One is to use water vapor to break the cigarette paper on the surface of the cigarette to separate the tobacco. Due to the contact of tobacco with water and air, it is easy to cause color change, breakage, and mildew, resulting in tobacco degradation and low tobacco recycling efficiency. The other method is the air blowing recovery method. This method separates the tobacco from the outer packaging paper tube of the cigarette by blowing air into the outer packaging paper tube of the cigarette. For filter cigarettes, this method can only separate the airflow in one direction, which affects the application range of the equipment.

[0003] In the prior art, the patent document with the authorization announcement number "CN106723322A" discloses an online re-blending device for defective and thin tobacco in a cigarette machine, comprising a frame, a sorting device, a cigarette-rubbing assembly, a separating device, a main motor, a material collection system, a sorting and direction adjustment system, and a drop hopper; the drop hopper is mounted on the top of the frame, the sorting device, the cigarette-rubbing assembly, the separating device, and the main motor are mounted on the upper part of the frame, the sorting device, the cigarette-rubbing assembly, and the separating device are mounted in order from top to bottom, the dropping system is connected to the material collection system at the bottom of the frame, and the sorting device, the cigarette-rubbing assembly, and the separating device are driven by the main motor. Using this patented technical solution, the cigarette-rubbing assembly loosens the outer packaging paper tube of the cigarettes, making the tobacco shreds easier to screen and remove. However, in the process of the cigarettes passing through the cigarette-rubbing assembly, due to the large randomness of the cigarette postures, multiple cigarettes are squeezed together, which easily causes the cigarette conveying channel to be blocked, affecting the continuous and stable operation of the equipment.
