[0042] Combine the following Figure 1-2 The technical solution of the utility model is further illustrated through specific implementation methods.
[0043] In cigarette production, a drum-type tobacco drying is generally used. The tobacco to be dried is added to the drum through a feeding device, and hot air is blown into the feeding device by a hot air blower. The hot air can preheat the tobacco and improve the drying effect. However, the hot air in the feeding device is in direct contact with the tobacco, resulting in less feeding each time, and it is also easy to cause tobacco dust, and the feeding effect is not good.
[0044] In order to solve the above problems, the embodiment of the utility model provides a feeding device, which includes a feeding barrel 1, a feeding assembly 2 and a medium pipeline 3. The feeding barrel 1 is provided with a feed port 11 and a discharge port 12, and the feeding barrel 1 is used to transport and discharge materials; the feeding assembly 2 is provided on the feeding barrel 1, and the feeding assembly 2 extends into the feeding barrel 1 to push the material from the feed port 11 to the discharge port 12; the medium pipeline 3 is sleeved on the outside of the feeding barrel 1, and the medium pipeline 3 has a medium inlet 31 and a medium outlet 32, and the medium pipeline 3 is used to transport hot air, and the hot air can heat the material in the feeding barrel 1. Specifically, the material is added through the feed port 11 on the feeding barrel 1, and the hot air is sent in through the medium inlet 31 at the same time, and the material is pushed to the discharge port 12 by the feeding assembly 2. The feeding device sleeves the medium pipeline 3 on the outside of the feeding barrel 1, so that the material in the feeding barrel 1 does not directly contact with the medium, which can effectively avoid dust, and can also play a role in preheating the material.
[0045] In this embodiment, the medium pipeline 3 is coaxially arranged with the feed barrel 1, and the medium pipeline 3 surrounds the outer side of the feed barrel 1. The medium pipeline 3 is arranged to ensure that the medium does not directly contact the material. The medium pipeline 3 is fixedly connected to the feed barrel 1 through a connecting plate. Optionally, four connecting plates are provided, which are distributed at 90° intervals along the circumference of the feed barrel 1. Furthermore, a medium inlet 31 is provided on the side wall of the medium pipeline 3 for introducing hot air, and preheating the material by heating the barrel wall of the feed barrel 1. The end of the medium pipeline 3 away from the discharge port 12 is closed, and the end close to the discharge port 12 is open as a medium outlet 32 for conveying hot air. Optionally, the medium outlet 32 is located in the middle of the feed barrel 1.
[0046] In order to further avoid the material from raising dust during feeding, both ends of the feeding barrel 1 along the axial direction are closed, and the feed port 11 and the discharge port 12 are both arranged on the barrel wall of the feeding barrel 1, which is convenient for feeding and discharging, and also avoids the material from raising dust. Optionally, both ends of the feeding barrel 1 along the axial direction are closed by end caps 5, and flanges are arranged at both ends of the feeding barrel 1, and the end caps 5 are connected to the feeding barrel 1 through the flanges.
[0047] In this embodiment, the feeding device also includes a feeding barrel 4, which is arranged on the feeding barrel 1, and has a feeding port 41 and a discharging port 42, and the discharging port 42 is connected to the feeding port 11 on the feeding barrel 1. The feeding barrel 4 is provided with a material storage cavity, and the material is stacked in the material storage cavity, and the material is automatically discharged by using the dead weight and fluidity of the material. Further, the feeding barrel 4 is set to be conical, and the size of the feeding port 41 is larger than the size of the discharging port 42, so that the material can enter the feeding barrel 1 conveniently.
[0048] like Figure 1-2 As shown, the feeding assembly 2 includes a driving member, a transmission member and a spiral feeding rod 21. The driving member is arranged on one end of the feeding barrel 1 close to the feed port 11, the transmission member is rotatably arranged in the feeding barrel 1, the spiral feeding rod 21 is rotatably arranged in the feeding barrel 1, and is arranged along the axial direction of the feeding barrel 1, one end of the transmission member is connected to the driving member, and the other end is connected to the spiral feeding rod 21, the driving member drives the spiral feeding rod 21 to rotate through the transmission member, thereby pushing the material from the feed port 11 to the discharge port 12.
[0049] Specifically, the driving part adopts an asynchronous motor, which has a large starting torque, a simple structure and good stability. The transmission part adopts a gear, and the asynchronous motor is connected to the gear through a belt to drive the gear to rotate. A motor seat is provided at one end of the feeding barrel 1 close to the feeding port 11 for fixing the motor, and a through hole is provided in the center of the seat for installing a spiral feeding rod 21. The material is pushed to the discharge port 12 through the rotation of the spiral feeding rod 21, which effectively avoids blockage caused by material adhesion and ensures the uniformity of feeding.
[0050] Furthermore, the outer side of the spiral feeding rod 21 has a spiral portion, which extends from the feed port 11 toward the discharge port 12 and at least extends to the discharge port 12. The rotation direction of the spiral portion is left-handed or right-handed, that is, the spiral portions on the spiral feeding rod 21 all extend in one direction, and the rotating spiral pushes the material to the discharge port 12.
[0051] Alternatively, the discharge port 12 is arranged on the wall of the feeding barrel 1, the spiral feeding rod 21 has a first end and a second end, and the outer side of the spiral feeding rod 21 has a first spiral portion 211 and a second spiral portion 212, the rotation direction of the first spiral portion 211 and the rotation direction of the second spiral portion 212 are opposite, the first spiral portion 211 extends from the first end to the side of the discharge port 12 close to the first end, and the second spiral portion 212 extends from the second end to the side of the discharge port 12 close to the second end, that is, the discharge port 12 has no spiral, thereby ensuring that the material is accurately discharged at the discharge port 12.
[0052] The utility model also provides a wire drying device, which includes a drum, a hot air blower and a feeding device. The drum is sleeved on the outside of the feeding drum 1, and the discharge port 12 is located on the inside of the drum. The drum is connected to one end of the medium pipeline 3 where the medium outlet 32 is provided, and the hot air blower is connected to the medium inlet 31 of the feeding device, which is used to blow hot air into the medium pipeline 3. The material enters the drum from the discharge port 12 of the feeding drum 1, and the hot air enters the medium pipeline 3 from the medium inlet 31 to preheat the material in the feeding drum 1. Then, the hot air enters the drum from the medium outlet 32, and the drum dries the material. In this process, the hot air does not directly contact the material, which avoids the dust of the material when the device is charged, and the hot air can preheat the material in the feeding device. The hot air and the material enter the drum in the same direction, which improves the drying effect of the material.
[0053] The embodiment of the utility model also provides a cigarette production line, which includes tobacco drying equipment to improve the quality of cigarettes.
[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
