Description

Technical Field

[0001] The utility model relates to the technical field of tobacco blending, in particular to a loose material equalizing device and a conveying line. Background Art

[0002] Tobacco processing involves multiple mixing steps, and solid material mixing occurs throughout the entire process. The better the mixing, the more stable the product's physical and sensory qualities. Cut tobacco blending is a crucial part of this mixing process. In cigarette production, proportional blending involves accurately and evenly blending cut stems, expanded cut tobacco, reconstituted cut tobacco, and recycled cut tobacco into dried cut tobacco according to the product formulation. This is a critical step in achieving consistent cut tobacco content across all product components, and blending uniformity directly impacts the inherent quality stability of the cigarette product.

[0003] The conventional production model of proportional blending is used in the prior art. The principle of proportional blending is to use a cut tobacco scale as the primary scale, and scales for cut stems, expanded cut tobacco, and reconstituted tobacco as secondary scales. During production, the scales are pre-set with a specific ratio, automatically tracking the cut tobacco scale flow rate and adjusting the flow rates of each scale based on fluctuations in the cut tobacco scale flow rate to achieve the desired blending ratio for different cut tobacco components. During the proportional blending process, expanded cut tobacco is relatively fluffy and easily entangled. This makes it difficult to adjust the material shape after conveying it through the belt scale, affecting the uniformity of the blending ratio and the quality of the cigarettes.

[0035] In the prior art, tobacco cuts are typically blended using a proportional blending model. This involves a cut tobacco scale as the primary scale, and scales for stem cuts, expanded cut tobacco, and reconstituted cut tobacco as secondary scales. During production, the scales pre-set the ratios and automatically track the cut tobacco scale flow rate. The flow rates of the various scales are adjusted based on changes in the cut tobacco scale flow rate, achieving the desired blending ratio for each component. However, during the proportional blending process, expanded cut tobacco is relatively fluffy and easily entangled. This makes it difficult to adjust the material shape after conveying it through the belt scale, impacting the uniformity of the blending ratio and the quality of the cigarettes.

[0036] To solve the above problems, this embodiment provides a conveyor line including a loose material distribution device. Figure 1 The loosening and evenly distributing equipment includes a first conveyor belt, a vibrating loosening device 20 and an evenly distributing device 30. The first conveyor belt conveys expanded tobacco along a first direction. The vibrating loosening device 20 includes a conveying trough 21 and a vibrating assembly 22. The conveying trough 21 is tilted along the first direction at the output end of the first conveyor belt. The first conveyor belt outputs the expanded tobacco to the conveying trough 21. The vibrating assembly 22 can drive the conveying trough 21 to vibrate to loosen the expanded tobacco. The evenly distributing device 30 includes an evenly distributing trough 31 and an evenly distributing baffle 32. The evenly distributing trough 31 is provided below the front end of the conveying trough 21 along the first direction to receive the loosened expanded tobacco. The evenly distributing baffle 32 is provided in the evenly distributing trough 31 to evenly spread the expanded tobacco. The expanded tobacco is loosened by the vibrating loosening device 20 and evenly spread by the evenly distributing baffle 32, thereby avoiding the problem of inaccurate blending amount of the expanded tobacco due to entanglement and irregular shape, thereby improving the uniformity of the proportion blending and the quality of the cigarette.

[0037] Specifically, the loose material grading device includes a belt scale 10, a first conveyor belt is arranged inside the belt scale 10, and is used to transport expanded tobacco shreds. The grading device 30 is configured as a conveyor, including a second conveyor belt, which is laid along a first direction inside the grading trough 31 to transport expanded tobacco shreds. In this embodiment, refer to Figure 2 There are two equalizing baffles 32, forming an equalizing opening. The lower end surfaces of the equalizing baffles 32 are in contact with the surface of the second conveyor belt. The expanded tobacco shreds fall into the equalizing trough 31 and, driven by the second conveyor belt, move in the first direction. When the expanded tobacco shreds reach the equalizing opening, the equalizing baffles 32 block the expanded tobacco shreds, allowing them to pass through the equalizing opening evenly in a loose state, facilitating precise proportioning. In other embodiments, a single equalizing baffle 32 may be provided, extending in a direction perpendicular to the first direction, with an equalizing opening formed between the equalizing baffle 32 and the lower end surface of the second conveyor belt.

[0038] Furthermore, the material distribution device 30 also includes a rotating shaft 33, which is arranged vertically in the material distribution trough 31. A sleeve 321 is provided at one end of the material distribution baffle 32. The sleeve 321 is sleeved on the rotating shaft 33 and has a clearance fit with the rotating shaft 33. The rotating shaft 33 and the sleeve 321 can be used to adjust the inclination angle of the two material distribution baffles 32, thereby adjusting the size of the material distribution opening to control the flow rate of the expanded tobacco.

[0039] Further, see Figure 3The vibration assembly 22 includes a driver 221 and a rocker arm 222. One end of the rocker arm 222 is connected to the conveying trough 21, and the other end is connected to the driver 221. The driver 221 drives the conveying trough 21 to vibrate through the rocker arm 222. In this embodiment, the driver 221 is configured as a vibration motor. In other embodiments, the driver 221 can also be configured as a pneumatic cylinder or an electric cylinder, so that the rocker arm 222 is rotatably connected to the driver 221, thereby driving the rocker arm 222 to vibrate.

[0040] Specifically, the vibrating loosening device 20 also includes a fixing buckle 23, through which the driving member 221 is secured to the underside of the first conveyor belt. Specifically, the fixing buckle 23 is provided on the side wall of the belt scale 10, and the driving member 221 is secured to the belt scale 10 via the fixing buckle 23. In other embodiments, fasteners may be used in place of the fixing buckle 23 to secure the driving member 221.

[0041] Furthermore, the vibration loosening device 20 further includes a connecting member 24, which is provided at the bottom of the conveying trough 21, and the rocker arm 222 is connected to the conveying trough 21 via the connecting member 24. Specifically, the connecting member 24 is configured as a connecting plate, and the rocker arm 222 and the connecting plate can be connected using fasteners, adhesive bonding, or clamping, which is not limited here.

[0042] Further, see Figure 4 The loosening and leveling device further includes two guide plates 40, which are arranged inwardly and tilted at the output end of the first conveyor belt to form a guide port. The expanded tobacco enters the conveying trough 21 through the guide port. The guide port can effectively guide the expanded tobacco into the vibrating loosening device 20 for vibration loosening, preventing the tobacco from being thrown out.
