Processing, to ensure the uniformity of tobacco in different intervals on the same production line, the distances from the air inlet 6 to the two ends of the uniform air duct 3 in the length direction are equal, and a diverter block 5 is fixedly provided inside the uniform air duct 3. On the one hand, by setting the air inlet 6 to be equal in distance at both ends of the uniform air duct 3, and at the same time, setting a diverter block 5 in the middle of the uniform air duct 3, the fluid is evenly diverted to improve the uniform fluid transportation on the air outlet duct 7 in the uniform air duct 3. On the other hand, a mounting plate 10 is provided on the air outlet duct 7, and the mounting plate 10 is fixedly connected to the air outlet duct 7. An air outlet hole 12 is opened on the mounting plate 10, and the air outlet hole 12 is connected to the inside of the uniform air duct 3. The air outlet hole 12 is set, and the fluid is transported through the air outlet hole 12. At the same time, a certain pressure is required to pass through the air outlet hole 12 to achieve uniform transportation of the fluid at the end of the air outlet duct 7.
[0026] Please refer to Figure 1-3 As shown, a mounting cavity 2 is formed in the air chamber box 1, the uniform air duct 3 is located in the mounting cavity 2, one end of the air inlet 6 is fixedly connected to one end of the air chamber box 1 through a flange, and the mounting cavity 2 is used for mounting and connecting the uniform air duct 3, so that the two ends of the uniform air duct 3 are fixedly connected to the inner wall of the mounting cavity 2, and at the same time, the air inlet 6 is fixedly connected to the air chamber box 1 through the flange, and the air inlet 6 is used to connect an external fluid pipeline to realize the input of fluid into the uniform air duct 3.
[0027] Please refer to Figure 1-3 As shown, the air inlet 6 is connected with an input pipe 8, and the input pipe 8 is communicated with the air inlet 6. The input pipe 8 is used to connect to an external pipe for conveying fluid. One end of the input pipe 8 away from the air inlet 6 is connected with a flow control valve (not shown). The flow control valve is an existing conventional technology, and only needs to realize the control of the input flow of the uniform air duct 3. By controlling the input flow of the uniform air duct 3, the processing speed of the processing area can be matched to realize the uniform conveying of the tobacco fluid.
[0028] Please refer to Figure 3As shown, an air duct cavity 4 is formed inside the uniform air duct 3, and the flow duct cross-section of the uniform air duct 3 cavity along the direction from the air inlet 6 to the air outlet 7 gradually increases, which effectively increases the output area of the air outlet 7. At the same time, the tobacco on the production line is processed synchronously, thereby improving the production efficiency. The diverter block 5 is fixedly connected to the inner walls of the upper and lower ends of the diverter block 5 and the air duct cavity 4.
[0029] Please refer to Figure 4 As shown, the diverter block 5 is ellipsoidal, and the distances from the diverter block 5 to the two ends of the uniform air duct 3 are equal. The diverter block 5 realizes the diversion of the fluid in the air duct cavity 4, so that the fluid is diverted on the side of the air inlet 6 under the action of the diverter block 5, so that the amount of fluid reaching the two ends of the air outlet 7 tends to be consistent, effectively ensuring the uniformity of fluid transportation.
[0030] Please refer to Figure 1 , 6 As shown, the air outlet holes 12 are provided in plurality, and the plurality of air outlet holes 12 are evenly distributed in multiple rows on the mounting plate 10. By arranging the plurality of air outlet holes 12 at the air outlet duct 7, the air outlet holes 12 can allow the fluid in the uniform air duct 3 to pass through only when a certain pressure is formed, so that the fluid can be output only when the uniform air duct 3 is filled with enough fluid. Since the aperture of each air outlet hole 12 is consistent, when a certain pressure is formed inside the uniform air duct 3, the fluid is evenly discharged through the plurality of air outlet holes 12. At the same time, with the distribution of the positions of the diverter block 5 and the air inlet 6, the uniform distribution of the fluid is achieved, ensuring that the fluid output at different positions at the output end of the air outlet duct 7 is consistent, thereby effectively improving the uniformity of the tobacco and the consistency of the filling density, and the uniformity of the tobacco bundles formed during the filling process is consistent.
[0031] Please refer to Figure 1 , 6 As shown, a guide plate 11 is provided on the side of the air outlet 12 away from the air inlet 6, and the guide plate 11 is distributed along the length of the air outlet 7, and both ends thereof are rotatably connected to the air chamber box 1. By providing a rotatably adjustable guide plate 11 on one side of the air outlet 12, the guide plate 11 can guide the fluid output from the air outlet 12 to transport the fluid in different directions, and change the output position of the fluid to match the positions of tobacco placed at different heights on the processing equipment.
[0032] Please refer to Figure 2 As shown, fixing rings 9 are symmetrically provided at both ends of the length of the air chamber box 1. The fixing rings 9 are fixedly connected to the air chamber box 1 and are located on one side of the input pipe 8. The fixing rings 9 are used to realize the fixed installation connection between the device and the processing equipment.
[0033] Working principle of this utility model:
[0034] Connect the fixing ring 9 to the fixed position on the processing equipment to realize the integrated installation connection between the device and the processing equipment. At the same time, connect the input pipe 8 to the external fluid input pipe and the fluid equipment to realize the input of fluid from the input pipe 8 to the uniform air duct 3.
[0035] The fluid is transported by the input pipe 8, flows through the air inlet 6, the air duct cavity 4, the air outlet 7, and the air outlet 12 in sequence, and is finally transported to the tobacco by the guidance of the guide plate 11, so as to achieve uniform blowing of the tobacco. Among them, since the air inlet 6 is arranged in the middle of the air duct cavity 4, the distance between the two ends of the uniform air duct 3 is equal. After the fluid flows through the air inlet 6, the fluid flows evenly to the two ends of the air duct cavity 4 to a certain extent. After the fluid flows through the air inlet 6, the fluid in the air duct cavity 4 is diverted by the diverter block 5 to ensure uniformity. The flow rates of the input fluid at both ends of the uniform air duct 3 in the length direction tend to be consistent. At the same time, since a plurality of air outlet holes 12 are provided at the air outlet duct 7, the fluid needs to form a certain pressure in the air duct cavity 4 when passing through the air outlet holes 12. After a certain pressure is formed in the air duct cavity 4, the fluid in the air duct cavity 4 is driven to pass through each air outlet hole 12 evenly to achieve consistency in the air outlet volume, thereby ensuring uniform blowing of the tobacco shreds and the uniformity of the tobacco shreds formed during the filling process. The filling density tends to be consistent, thereby avoiding different empty rates and qualities of cigarettes.
