Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a rotary tobacco impurity removal and remixing device. 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 cigarettes in a cigarette machine, comprising a frame, a sorting device, a cigarette rubbing component, a separating device, a main motor, a material receiving system, a sorting and direction adjustment system, and a drop hopper; the drop hopper is installed on the top of the frame, the sorting device, the cigarette rubbing component, the separating device, and the main motor are installed on the upper part of the frame, the sorting device, the cigarette rubbing component, and the separating device are installed in sequence from top to bottom, the dropping system is connected to the material receiving system at the bottom of the frame, and the sorting device, the cigarette rubbing component, and the separating device are driven by the main motor. By adopting this patented technical solution, the posture and direction of the cigarette entering the separation wheel are pre-identified, so that the compressed air flow will not blow out the tobacco in the opposite direction of the cigarette filter, thereby improving the efficiency of tobacco recycling to a certain extent. However, in the process of recycling defective cigarette tobacco, due to the influence of the environment and the limitations of process conditions, a large amount of impurities such as paper scraps, filter tips and other materials are easily mixed into the tobacco. These debris must be removed in time to facilitate the timely recycling of the tobacco. In the existing technology, a vibrating screen is generally used to remove the debris. However, the vibrating screen is relatively expensive, resulting in a complex structure of the screening equipment, high investment cost, and high requirements for control accuracy and control difficulty, which is not convenient for widespread promotion and application.

[0021] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0022] The utility model provides a rotary tobacco impurity removal and remixing device, such as Figures 1 to 3 As shown, it includes a feed pipe 1, a first end plate 2, a second end plate 3, a motor 4 and multiple screening rollers 5. The feed pipe 1 is installed on the first end plate 2 using a rolling bearing, the second end plate 3 is fixedly connected to the output shaft of the motor 4, and the screening rollers 5 are fixedly connected between the first end plate 2 and the second end plate 3.

[0023] By adopting the technical solution of the present invention, when tobacco mixed with impurities is fed into between the first end plate and the second end plate through the feed pipe, the posture of the tobacco is adjusted as the screening roller rotates, so that its length direction is close to the length direction of the screening roller. Due to its small size, the tobacco falls out through the gap between the two adjacent screening rollers, while paper scraps, filter tips and other impurities can only fall out from the slag discharge holes due to their large external dimensions, thereby realizing the separation and screening of tobacco and impurities, and timely removing impurities from the tobacco. Compared with the existing technology, it is less difficult to control the continuous unidirectional rotation movement of the motor, and the present invention has a simple structure and low investment cost, and is suitable for wide promotion and application.

[0024] Specifically, the first end plate 2 and the second end plate 3 are both in the shape of annulus, the screening roller 5 is in the shape of a cylinder, and a plurality of screening rollers 5 are evenly arranged in an array around the first end plate 2 or the second end plate 3 .

[0025] In addition, a distribution tray 6 is provided between the first end plate 2 and the second end plate 3. The distribution tray 6 is conical in shape, and the bottom of the distribution tray 6 is fixedly connected to the output shaft of the motor 4, while the top of the distribution tray 6 is aligned with the orifice of the feed pipe 1. With the technical solution of the present utility model, the distribution tray is used to distribute the material initially entering between the first end plate and the second end plate as close to the first end plate as possible, so that the material must be screened and impurity-removed before being re-mixed and reused, avoiding omissions in the screening and impurity-removal process of the material.

[0026] In addition, the second end plate 3 is fixedly connected to one end of a discharge barrel 7, the other end of which extends to the periphery of the first end plate 2. The discharge barrel 7 is also supported on a receiving hopper 8, which is disposed below the first end plate 2. The discharge barrel 7 is preferably conical in shape as a whole. Using the technical solution of the present invention, tobacco shredded from the material mixed with impurities first passes through the gap between two adjacent screening rollers and falls into the discharge barrel. Due to the outer conical shape of the discharge barrel, the tobacco shreds can slide down into the receiving hopper under their own gravity and then be transported outward.

[0027] Specifically, the screening roller 5 can be replaced by stainless steel wire, thereby significantly reducing the manufacturing cost of the present invention. The surface of the second end plate 3 is also provided with a plurality of slag discharge holes 9, and a slag collecting trough 10 is also provided below the second end plate 3. The rotary tobacco impurity removal and remixing device also includes a slag guide trough 11, one end of which is provided below the slag discharge holes 9, and the other end of which is provided above the slag collecting trough 10. The receiving hopper 8 is also fixedly connected to one end of the remixing pipe 12, the other end of which extends outward. A screw conveyor is also installed in the remixing pipe 12.
