Description

Technical Field

[0001] This utility model relates to the technical field of cigarette processing equipment, and more specifically to an adjustable material guiding device for a leaf air separator. Background Technology

[0002] To ensure the quality and safety of tobacco products, their moisture content needs to be strictly controlled. Due to differences in process flow parameters among different brands, some brands have a higher flow rate of 7200 kg / h for their leaf shred air separators, while others have a lower flow rate of 3600 kg / h. This results in uneven material distribution at the outlet of the leaf shred air separator, inconsistent fabric thickness, and even instances where the material is not fully distributed in the detection area of ​​the moisture meter probe. This leads to larger errors in the moisture meter data, hindering the monitoring and adjustment of moisture content and increasing the difficulty and risk of process control. Utility Model Content

The piston rod of the cylinder is connected to the guide plate through a connecting structure. The guide plate and the connecting structure are rotatably connected. By extending and retracting the piston rod of the cylinder, the guide plate is driven to rotate around the first hinge shaft, thereby adjusting the width of the material guiding channel.

[0016] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0017] See Figures 1 to 2This embodiment discloses an adjustable material guiding device for a leaf-filament air classifier. The adjustable material guiding device includes two sets of material guiding components 1 arranged opposite each other on the left and right sides of the discharge conveyor belt of the leaf-filament air classifier. Each set of material guiding components 1 includes a guide plate 2. A material guiding channel 3 is formed between the guide plates 2 of the two sets of material guiding components 1. The top of one end of the guide plate 2 is mounted on the frame of the discharge conveyor belt through a first bracket 4. The top of one end of the guide plate 2 is rotatably connected to the first bracket 4 through a vertically extending first hinge shaft 5. The top of the other end of the guide plate 2 is connected to a cylinder 6. The cylinder body of the cylinder 6 is rotatably mounted on a second bracket 11 fixed to the frame of the discharge conveyor belt. The piston rod of the cylinder 6 is connected to the guide plate 2 through a connecting structure. The guide plate 2 is rotatably connected to the connecting structure. By extending and retracting the piston rod of the cylinder 6, the guide plate 2 is driven to rotate around the first hinge shaft 5, thereby adjusting the width of the material guiding channel 3. The bottom of the guide plate 2 is equipped with a baffle curtain, which seals the gap between the bottom of the guide plate 2 and the discharge conveyor belt to prevent material leakage.

[0018] The bottom of the first support 4 is fixedly installed on the frame of the discharge conveyor belt. The rod end of the first rod end spherical bearing 7 is fixedly installed on the top of the first support 4. The bearing end of the first rod end spherical bearing 7 is rotatably connected to the top of one end of the guide plate 2 through the first hinge shaft 5. The top of the guide plate 2 is provided with a fixing rod 8, and the guide plate 2 is rotatably connected to the bearing end of the first rod end spherical bearing 7 through the fixing rod 8.

[0019] The connecting structure includes a second rod end spherical bearing 9. The rod end of the second rod end spherical bearing 9 is fixedly connected to the piston rod of the cylinder 6. The bearing end of the second rod end spherical bearing 9 is rotatably connected to the top of the other end of the guide plate 2 via a vertically extending second hinge shaft 10. The guide plate 2 is rotatably connected to the bearing end of the second rod end spherical bearing 9 via a fixing rod 8.

[0020] During operation, the piston rods of the two sets of cylinders 6 can extend and retract, thereby driving the two guide plates 2 to rotate around their respective first hinge axes 5, thus adjusting the width of the guide channel 3 formed by the gap between the two guide plates 2. When the material flow rate is large, the two guide plates 2 can be adjusted to be parallel, at which point the guide channel 3 is widest, which can accommodate the centered and uniform conveying of materials with a large flow rate. When the material flow rate is small, the included angle between the two guide plates 2 can be adjusted to an acute angle, so that the width of the guide channel 3 gradually narrows towards the center along the conveying direction, allowing materials with a small flow rate to be conveyed centered and uniformly, ensuring uniform material distribution, thus ensuring that the material is evenly spread in the detection area of ​​the moisture meter probe, and ensuring the accuracy of the data collected by the moisture meter.

[0021] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
