Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a device for separating defective cigarettes and tobacco paper tubes. 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 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. This patented technical solution pre-identifies the posture and direction of cigarettes entering the separation wheel, so that the compressed airflow will not blow out tobacco in the opposite direction of the cigarette filter, thereby improving the efficiency of tobacco recycling to a certain extent. However, due to the use of a large number of detection elements, this technical solution greatly increases the complexity of the equipment structure and the corresponding process method. In addition, due to the humid indoor environment and other reasons, the outer packaging paper tubes of cigarettes after friction with the cigarette rubbing plate are easily attached to the outer surface of the smoke catching wheel and are not easy to remove, which not only affects the stable operation of the equipment, but also makes the paper tubes difficult to collect.

The smoke catching device 4 includes a plurality of smoke catching wheels 6 and a plurality of cigarette rubbing plates 10. The cigarette rubbing plates 10 correspond to the smoke catching wheels 6 one by one and are arranged in pairs in a top-down order. The gap between the cigarette rubbing plates 10 and the smoke catching wheels 6 forms a cigarette branch flow channel 48. The two adjacent cigarette branch flow channels 48 are connected to each other end to end. A paper picking groove 29 is provided on the outer peripheral surface of the smoke catching wheel 6. The paper picking groove 29 is annular and is arranged between two adjacent smoke catching wheels 6. One end of the inter-wheel stripping knife 26 is fixedly connected to the cigarette rubbing plate 11, and the other end of the inter-wheel stripping knife 26 extends into the corresponding paper picking groove 29 of the previous smoke catching wheel 6.

[0030] By adopting the technical solution of the present invention, after the defective cigarettes collected from the output end of the cigarette production line are put into the hopper, in the process of transferring the defective cigarettes through multiple cigarette flow channels, the smoke-catching wheel and the cigarette-rubbing plate both generate friction on the outer packaging paper tube of the cigarettes, making the paper tube soft and causing some paper tubes to wear, making it easier to recycle and collect the tobacco. After the tobacco in the cigarettes is collected, if the residual paper tube or paper scraps adhere to the surface of the smoke-catching wheel, they can be scraped off in time by the inter-wheel stripping knife. The scraped paper tube or paper scraps are transferred to the chip collecting trough through multiple cigarette flow channels for collection, avoiding arbitrary discard that affects environmental hygiene, thus ensuring the stable operation of the equipment and making it easier to collect the paper tubes.

[0031] Specifically, the ratio of the number of the inter-wheel stripping knives 26 to the number of the cigarette rubbing plates 10 is 3:1, and every three inter-wheel stripping knives 26 are arranged on the cigarette rubbing plates 10 at equal intervals along the axial direction of the smoke catching wheel 6 .

[0032] Preferably, the smoke catching wheel 6 and each of the three inter-wheel stripping blades 26 are integrally manufactured, thereby reducing the manufacturing cost of the equipment.

[0033] Furthermore, the frame 1 is provided with a knife holder 25 and a terminal stripper 27. The surface of the knife holder 25 is provided with several slots 28. One end of the terminal stripper 27 is inserted into the slot 28, and the other end of the terminal stripper 27 extends into the corresponding paper removal slot 29 of the last smoke-catching wheel 6. Preferably, there are three terminal strippers 27, which are evenly spaced along the axial direction of the smoke-catching wheel 7. The technical solution of the present utility model allows the terminal stripper 27 to promptly scrape away paper scraps or paper tubes adhering to the surface of the last smoke-catching wheel 7, ensuring the continued stable operation of the equipment. The paper scraps or paper tubes are also promptly collected and cleaned to prevent them from affecting the sanitary environment of the production site.

[0034] In addition, the smoke-catching device 4 also includes a plurality of driven gears 8. The smoke-catching wheels 6 correspond to the driven gears 8 one by one and are arranged in pairs. Each pair of smoke-catching wheels 6 and driven gears 8 are coaxially fixed together, and two adjacent driven gears 8 are meshed with each other. The smoke-catching device 4 also includes a main motor 17. The output shaft of the main motor 17 is fixedly connected to the driving gear 18, and the driving gear 18 is meshed with one of the driven gears 8. Preferably, the number of smoke-catching wheels 6 or driven gears 8 is 2. Compared with the prior art, the technical solution of the present invention does not require the installation of complex detection equipment to detect the posture direction of the cigarette, which is conducive to simplifying the equipment structure and simplifying the process steps. By blowing compressed air into both sides of the cigarette trough and performing air-blowing separation treatment on the tobacco when the cigarette is transferred and transported through multiple cigarette flow channels, the tobacco in the cigarette paper tube can be completely blown clean, thereby improving the efficiency of tobacco recycling.

[0035] Specifically, the top of the frame 1 is also fixedly connected to the drop hopper 2, and the first branch cigarette flow channel 48 is connected to the drop hopper 2. The frame 1 also has a cigarette prying device 19, which includes a cigarette prying gear 20. The cigarette prying gear 20 is arranged at the entrance of the first branch cigarette flow channel. By adopting the technical solution of the utility model, by installing the cigarette prying device at the entrance of the first branch cigarette flow channel, the rotation direction of the cigarette prying gear 20 is opposite to the rotation direction of the corresponding smoke catching wheel 6, which can provide a boost to the forward conveying force of the cigarettes, thereby preventing cigarettes from getting stuck at the entrance of the first branch cigarette flow channel.

[0036] In addition, the smoke-prying device 19 also includes a first pulley 21, a second pulley 22 and an auxiliary motor 23. The first pulley 21 is coaxially fixed to the smoke-prying gear 20, and the second pulley 22 is fixed to the output shaft of the auxiliary motor 23. The first pulley 21 and the second pulley 22 are meshed together through a transmission belt 24. Preferably, the first pulley 21 and the second pulley 22 are both synchronous pulleys, and the transmission belt 24 is a synchronous belt. A plurality of smoke-receiving grooves 12 are also provided on the outer peripheral surface of the smoke-catching wheel 6, and the length direction of the smoke-receiving grooves 12 is consistent with the axial direction of the smoke-catching wheel 6. By adopting the technical solution of the present invention, by arranging a smoke-prying device at the entrance of the first cigarette branch flow channel, the rotation direction of the cigarette-prying gear 20 is opposite to the rotation direction of the corresponding cigarette-catching wheel 6, which can provide assistance to the forward conveying force of the cigarette, thereby avoiding the cigarette from being stuck at the entrance of the first cigarette branch flow channel.

[0037] In addition, the defective cigarette and tobacco paper tube separation device also includes an air storage tank 3, and an air blowing pipe 13 and a smoke guide pipe 5 are also provided in the frame 1.

One side of the pressure block 32 is fixedly connected to the piston rod of the smoke compression cylinder 34, and the other side of the pressure block 32 is aligned with the limiting groove 33.

[0039] By adopting the technical solution of the present invention, after the defective cigarettes collected from the output end of the cigarette production line are put into the drop hopper, in the process of transferring the defective cigarettes through multiple cigarette flow channels, the smoke catching wheel and the cigarette rubbing plate respectively generate friction on the outer packaging paper tube of the cigarettes, causing the paper tube to wear or soften, thereby facilitating the recovery of the tobacco inside the paper tube; when the smoke pressing cylinder is activated and the defective cigarettes are clamped between the pressing block and the cigarette placing groove, the compressed air from the gas storage tank is blown into from the left or right side of the cigarette placing groove, so that the tobacco and the filter tip are collected into the smoke guide pipe through the right or left side of the cigarette placing groove, and then the filter tip and the cigarette are compressed. After the shredded tobacco is screened and separated, the usable shredded tobacco is mixed back into the input end of the cigarette production line, while the outer packaging paper tubes of defective cigarettes are transferred to the chip guide trough via multiple cigarette flow channels, and then transferred from the chip guide trough to the chip collection trough for collection. Compared with the existing technology, the present invention does not set up complex detection equipment to detect the posture direction of the cigarettes, which is conducive to simplifying the equipment structure and simplifying the process steps. By blowing compressed air into both sides of the cigarette trough and blowing and separating the tobacco when the cigarettes are transferred and transported through multiple cigarette flow channels, the tobacco in the cigarette paper tube can be completely blown clean, thereby improving the efficiency of tobacco recycling.
