Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to an automated mixing and blending device for tobacco processing. Background Technology

[0002] Tobacco processing is a crucial step in the tobacco manufacturing process. It involves a series of processing steps on raw tobacco leaves to transform them into shredded tobacco suitable for cigarette production. First, the tobacco leaves undergo pre-treatment such as rehydration and loosening. Then, a shredder cuts the leaves into shreds of a specific width. Next, processes like drying are performed to adjust the moisture content and temperature of the shredded tobacco to achieve suitable processing parameters. The processing also includes adding flavorings and aromatics to impart specific flavors and aromas to the shredded tobacco. Strict control of parameters at each stage is essential to ensure consistent quality of the produced shredded tobacco, meeting the quality requirements of cigarette products and providing consumers with high-quality tobacco products.

[0003] However, existing automated mixing and blending devices in the tobacco processing line are prone to clogging at the feed inlet during the initial feeding of tobacco shreds. This severely impacts subsequent production processes, preventing proper feeding. This not only reduces production efficiency but also negatively affects the quality and schedule of the entire tobacco processing line. Furthermore, resolving this issue requires significant time and effort from staff for troubleshooting and cleaning, increasing production costs and workload. Therefore, to address these shortcomings, an automated mixing and blending device for the tobacco processing line is proposed to solve these problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an automated mixing and blending device for tobacco processing, which aims to improve the problem that some tobacco mixing and blending devices in the prior art are prone to blockage during the feeding process, resulting in the inability to feed normally.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated mixing and blending device for tobacco processing includes a mixing tank.

[0007] A drive assembly for providing power is provided on the left side of the mixing tank. A drive shaft is fixedly connected to the outside of the drive assembly. The drive shaft is located inside the mixing tank. A cam is fixedly connected to the drive shaft. A mixing assembly for mixing tobacco is also provided on the drive shaft.

[0008] The mixing tank is slidably connected to a limiting plate on the left side, and a right-angle rod is fixedly connected to the right side of the limiting plate. The outside of the cam is in contact with the bottom of the right-angle rod.

[0009] A top cone is fixedly connected to the top of the right-angle rod, a connecting plate is fixedly connected to the left side of the right-angle rod, two sliding rods are fixedly connected to the top of the connecting plate, springs are sleeved on the outside of the two sliding rods, and limit plates are fixedly connected to the top of the two sliding rods. The two limit plates are located outside the mixing tank.

[0010] A feed pipe is fixedly connected to the top left side of the mixing tank, and a trapezoidal ring is fixedly connected to the top of the feed pipe. The top cone is located inside the feed pipe or the trapezoidal ring.

[0011] Preferably, the mixing component includes a plurality of connecting posts fixedly connected to the bottom of the drive shaft, a scooping frame fixedly connected to the outer end of the plurality of connecting posts, a plurality of dispersing rollers fixedly connected to the inside of the scooping frame, and a slot provided on the left side of the scooping frame;

[0012] The top of the drive shaft is fixedly connected to multiple docking rods, and two cross rods are fixedly connected between two adjacent docking rods. An arc-shaped scraper is fixedly connected to the top of the multiple docking rods.

[0013] Preferably, the outer end of the arc-shaped scraper is slidably connected to the inner wall of the mixing tank, and the outer end of the scooping frame is also slidably connected to the inner wall of the mixing tank.

[0014] Preferably, the drive component is a motor, the drive shaft is fixedly connected to the output end of the motor, and the drive shaft is rotatably connected inside the mixing tank.

[0015] Preferably, a limiting groove is formed on the left side of the inside of the mixing tank, and the outside of the limiting plate is slidably connected to the inside of the limiting groove.

[0016] Preferably, a discharge pipe is fixedly connected to the right side of the mixing tank, a valve is provided on the outside of the discharge pipe, a collection box is provided below the discharge pipe, and a filter plate is fixedly connected inside the collection box.

[0017] Preferably, a base is fixedly connected to the bottom of the mixing tank, and the collection box is fixedly connected to the base.

[0018] Preferably, a fixing plate is fixedly connected to the left side of the inside of the mixing tank, and the two sliding rods slide through the fixing plate.

[0019] Preferably, the two ends of the spring are fixedly connected to the fixing plate and the connecting plate, respectively.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the tobacco raw material enters the mixing tank through the trapezoidal ring and the feed pipe, the motor drives the drive shaft to rotate, which in turn causes the cam to make a circular motion. The cam intermittently squeezes the right-angle rod, causing the right-angle rod to move and compress the spring at the same time. This causes the top cone of the right-angle rod to slide up and down between the feed pipe and the trapezoidal ring, which can clear the channel in time, prevent the tobacco from accumulating and blocking, and thus ensure the normal feeding of tobacco and greatly improve work efficiency.

[0022] 2. In this utility model, when the drive shaft rotates, the scooping frame makes a circular motion inside the mixing tank. The scooping frame can scoop the tobacco raw material into its interior. When it moves to the top, the tobacco falls down, causing the tobacco to flow continuously inside the mixing tank, increasing the mixing opportunity and making the tobacco more evenly distributed in the mixing tank. This ensures that the tobacco is fully stirred and mixed in the mixing tank, guaranteeing the uniformity of the mixture. Attached Figure Description

[0031] One embodiment provided by this utility model:

[0032] An automated mixing and blending device for tobacco processing includes a mixing tank 1, which is the main structure of the entire automated mixing and blending device for tobacco processing, providing space for the installation and operation of other structures. A drive assembly for providing power is arranged on the left side of the mixing tank 1, and a drive shaft 3 is fixedly connected to the outside of the drive assembly, with the drive shaft 3 located inside the mixing tank 1.

[0033] The drive assembly can be motor 2, which is installed on the left side of the mixing tank 1. Motor 2 is the power source of the entire device, providing the necessary power for the mixing and blending of tobacco. Drive shaft 3 is fixedly connected to the output end of motor 2, and the outside of drive shaft 3 is rotatably connected to the inside of mixing tank 1. Drive shaft 3 is driven to rotate by motor 2.

[0034] A cam 4 is fixedly connected to the outside of the drive shaft 3, and the cam 4 rotates in a circular motion as the drive shaft 3 rotates. A mixing component for mixing tobacco is also provided on the drive shaft 3.

[0035] A limiting plate 5 is slidably connected to the inside left side of the mixing tank 1. The function of the limiting plate 5 is to restrict the movement direction of the right-angle rod 6, ensuring that the right-angle rod 6 can only slide in the specified direction. A limiting groove 11 is formed inside the left side of the mixing tank 1, and the outside of the limiting plate 5 is slidably connected to the inside of the limiting groove 11.

[0036] A right-angle rod 6 is fixedly connected to the right side of the limiting plate 5. The outside of the cam 4 is in contact with the bottom of the right-angle rod 6. During the rotation, the cam 4 will intermittently squeeze the right-angle rod 6 to cause displacement.

[0037] A top cone 7 is fixedly connected to the top of the right-angle rod 6. The top cone 7 slides up and down as the right-angle rod 6 moves. The top cone 7 is conical in shape and its function is to prevent the tobacco raw material from forming a blockage between the feed pipe 14 and the trapezoidal ring 15.

[0038] A connecting plate 8 is fixedly connected to the left side of the right-angle rod 6. Two sliding rods 9 are fixedly connected to the top of the connecting plate 8. Springs 10 are fitted around the outside of each sliding rod 9. The springs 10 achieve the reset of the top cone 7 through elastic deformation. Limiting plates 13 are fixedly connected to the top of each sliding rod 9. The limiting plates 13 are located outside the mixing tank 1. The sliding rods 9 achieve the up and down movement of the top cone 7 by sliding, ensuring its flexibility.

[0039] A feed pipe 14 is fixedly connected to the top left side of the mixing tank 1, and a trapezoidal ring 15 is fixedly connected to the top of the feed pipe 14. When the top cone 7 moves up and down, it is located inside the feed pipe 14 or the trapezoidal ring 15. A mixing component for mixing tobacco is provided outside the drive assembly.

[0040] A fixed plate 12 is fixedly connected to the inside left side of the mixing tank 1, and the two sliding rods 9 slide through the inside of the fixed plate 12. One end of the spring 10 is fixedly connected to the bottom of the fixed plate 12, and the other end of the spring 10 is fixedly connected to the top of the connecting plate 8.

[0041] Reference Figures 2 to 4 The mixing assembly includes multiple connecting pillars 16, the tops of which are fixedly connected to the bottom of the drive shaft 3. A scooping frame 17 is fixedly connected to the bottom of each connecting pillar 16, and its outer end is slidably connected to the inside of the mixing tank 1. Multiple dispersing rollers 18 are fixedly connected inside the scooping frame 17. A slot 19 is provided on the left side of the scooping frame 17 to facilitate tobacco flow within it. Multiple docking rods 20 are fixedly connected to the top of the drive shaft 3, and two cross rods 21 are fixedly connected to the outside of adjacent docking rods 20. An arc-shaped scraper 22 is fixedly connected to the top of each docking rod 20. The arc-shaped scraper 22 is slidably connected to the inside of the mixing tank 1, and its function is to scrape the tobacco off the inner wall of the mixing tank 1, preventing the tobacco from sticking to the inner wall and affecting the mixing effect.

[0042] When the drive shaft 3 drives the scooping frame 17 to make a circular motion, the scooping frame 17 can scoop the tobacco raw material into its interior. When it moves to the top, the tobacco will fall down and be dispersed and mixed by the cross rod 21 and the dispersing roller 18. The design of the scooping frame 17 allows the tobacco to be fully stirred and mixed in the mixing tank 1, which greatly improves the mixing efficiency and uniformity.

[0043] Reference Figure 1 and Figure 2A discharge pipe 23 is fixedly connected to the right side of the mixing tank 1. The discharge pipe 23 is the channel through which the mixed tobacco is discharged from the mixing tank 1. A valve 24 is installed on the outside of the discharge pipe 23, and a collection box 25 is located below the discharge pipe 23. The function of the collection box 25 is to collect the mixed tobacco. A filter plate 26 is fixedly connected inside the collection box 25. The filter plate 26 is usually made of metal mesh or other filter materials. The filter plate 26 has a certain pore size and filtration accuracy, which can filter out impurities and particles in the tobacco and improve the quality of the tobacco.

[0044] A base 27 is fixedly connected to the bottom of the mixing tank 1, and the collection box 25 is fixedly connected to the base 27.

[0045] The working principle of the automated mixing and blending device used in the above tobacco processing steps is as follows:

[0046] The tobacco raw material enters the mixing tank 1 through the trapezoidal ring 15 and the feed pipe 14. At this time, the motor 2 can be started to drive the drive shaft 3 to rotate, which in turn drives the cam 4 to make a circular motion. As the cam 4 rotates, it will intermittently squeeze the right-angle rod 6 to make it displace. At this time, it will drive the sliding rod 9 to move upward through the connecting plate 8, which will compress the spring 10. At this time, the top cone 7 will slide up and down between the feed pipe 14 and the trapezoidal ring 15, thereby preventing the tobacco raw material from forming a blockage between the feed pipe 14 and the trapezoidal ring 15.

[0047] Simultaneously, as the drive shaft 3 rotates, it drives the scooping frame 17 to make a circular motion, which can scoop the tobacco raw material into the scooping frame 17. When it moves to the top, it can sprinkle the tobacco inside the scooping frame 17 and use the cross bar 21 and the dispersing roller 18 to disperse and mix the tobacco, which can greatly improve the mixing efficiency and ensure the uniformity of the mixing. After the mixing is completed, the mixed tobacco can be dropped out through the valve 24 and the discharge pipe 23 into the collection box 25. After being filtered by the filter plate 26, the quality of the tobacco can be further improved.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
