Abstract
Description
Technical Field
[0001] This utility model relates to the field of leaf trimming machine technology, specifically a pneumatic hopper material handling device suitable for leaf trimming machine units. Background Technology
[0002] In the tobacco leaf re-drying process, the leaf-threshing and air-separating equipment is a crucial component for separating the leaves from the stems. Leaf threshing is a physical process that uses mechanical force to tear the tobacco leaves from the stems. A rotating beating roller is equipped with rough-surfaced cutting blades. During rotation, the roller maintains a certain gap with the fixed blades and the frame to allow the tobacco leaves to pass through. Due to the relative speed between the moving blades of the beating roller and the fixed blades and frame, the material is torn and struck as it passes through the beating machine. During this tearing process, the leaves are ripped from the stems, thus achieving stem-leaf separation. The threshed material is then discharged from the beating machine through the frame.
[0003] In the currently used leaf threshing machines, when the material is fed into the leaf threshing machine from the previous stage equipment during rotation, the material falls from above onto both sides of the threshing roller. Material falling onto the same side of the threshing roller has a better leaf threshing effect, while material falling onto different sides of the threshing roller has a poor leaf threshing effect. This results in uneven separation of material and stem, poor leaf threshing effect, low tobacco leaf yield, and low economic benefits. To address this, we propose a pneumatic hopper material adjustment device suitable for leaf threshing units. Utility Model Content

The two ends of the seated bearing 14 are respectively fixedly connected to the leaf-beater main housing 26, and a reversing plate 15 is installed on the column surface of the seated bearing 14.
[0019] It should be noted that the reversing plate 15 is a long strip of metal plate, which is fixedly installed inside the leaf beater by a bearing 14. It can rotate 60° clockwise (counterclockwise). Its function is to guide all the material to one side of the beating roller by rotating clockwise (counterclockwise), thereby improving the material leaf stem separation capability. The bearing 14 is connected to the reversing plate 15 installed inside the main housing 26 of the leaf beater and on the upper part of the beating roller. The angle of the reversing plate 15 is adjusted by the pneumatic control system to send the material to one side of the beating roller, thus solving the problem of material on both sides of the beating roller of the leaf beater.
[0020] A mounting base 21 is installed on the outside of the main housing 26 of the leaf cutter, and a double-eared seat 22 is provided inside the mounting base 21. A cylinder 9 is fixedly installed inside the double-eared seat 22, and a connecting rod 11 is connected to the piston rod end of the cylinder 9. The end of the connecting rod 11 is connected to the bearing 14 with a seat. A pneumatic control system is provided on the outside of the main housing 26 of the leaf cutter.
[0021] It should be noted that the connecting rod 11 is a common metal connector, connected to the bearing 14 with a seat on one side and to the cylinder 9 on the other side. Its function is to connect the bearing 14 with the cylinder 9 and provide support for the cylinder 9 to drive the reversing plate 15 to move. The cylinder 9 is installed on the outside of the blade blower main housing 26, and has its own magnetic switch and mounting base 21. Its lower side is connected to the connecting rod 11. Its function is to provide power for the angle adjustment of the reversing plate 15.
[0022] Please see Figure 3 The pneumatic control system includes a throttle valve 27, a solenoid valve 28, a pressure reducing valve 29, a PU tube 33, a silencer 34, and a limit switch 35. One end of the PU tube 33 is provided with a compressed air inlet pipe, and a threaded two-way valve 31 is provided at the connection between the PU tube 33 and the compressed air inlet pipe. The pressure reducing valve 29 and the solenoid valve 28 are installed on the outside of the PU tube 33. A silencer 34 is provided on the outside of the solenoid valve 28.

The ends of the two throttle valves 27 are connected to the cylinder 9 through a compression pipeline. A limit switch 35 is provided on the outside of the cylinder 9.
[0023] It should be noted that the device of this utility model is equipped with a controller for control. The electrical control part uses a Siemens S7-1500 series PL controller with PROFITNET interface and modular programming to realize on-site operable control. This utility model is based on the pneumatic control principle, using compressed air to drive the reversing plate 15 to move and adjust the distribution of material in the leaf beater. According to the incoming material and the rotation direction of the beating roller, the operator sets the angle of the reversing plate 15. The pneumatic control system determines the thrust and pull of the piston rod of the cylinder 9 according to the magnitude of the working force. The cylinder 9 drives the bearing 14 with seat through the connecting rod 11 to move, thereby controlling the adjustment angle of the reversing plate 15. When the material falls into the leaf beater, under the adjustment of the reversing plate 15, the material falls evenly to one side of the beating roller, improving the leaf beating effect. At the same time, the material is buffered under the action of the reversing plate 15, reducing the wear on the beating roller.
[0024] Please see Figure 3 A shut-off valve 30 is installed on the outside of the PU tube 33 between the threaded tee 31 and the pressure reducing valve 29.
[0025] It should be noted that the shut-off valve 30 mainly controls the switching of airflow, that is, cutting off or connecting the flow path of compressed air.

In addition, the design of the first PC thread straight-through 32 and the second PC thread facilitates quick installation and disassembly, simplifying the maintenance and repair of the equipment.
[0028] Please see Figure 2 A first observation window 1 is provided on one side of the main body 26 of the leaf cutter, and a second observation window 2 is provided on one side of the main body 26 of the leaf cutter located on the vertical plane of the first observation window 1.
[0029] It should be noted that the main housing 26 of the leaf cutter is equipped with a first observation window 1 and a second observation window 2, which facilitates the operator to observe the internal condition of the equipment, detect problems in a timely manner, and handle them.
[0030] Please see Figure 2 An external light is provided on the exterior of the leaf trimmer main housing 26, and a lampshade 6 is provided on the surface of the leaf trimmer main housing 26 outside the light.
[0031] It should be noted that the design of the lighting and lampshade 6 increases the visibility of the working environment and improves the safety and convenience of operation.
[0032] Please see Figure 2 The piston rod end of cylinder 9 is equipped with a Y-type double elbow joint 10, and the end of connecting rod 11 is rotatably connected to the Y-type double elbow joint 10.
[0033] It should be noted that a Y-type double elbow joint 10 is installed at the end of the piston rod of cylinder 9, and the connecting rod 11 is connected to cylinder 9 through this joint. This design makes the connection of the pneumatic system more flexible and avoids damage or uneven movement caused by excessive fixation.
