Abstract
Description
Technical Field
[0001] This utility model relates to the field of weighing device technology, and in particular to an air separation weighing device for a cigarette machine. Background Technology
[0002] The Zj119 cigarette rolling machine is a type of mechanical equipment used for rolling cigarettes, commonly used in the tobacco industry. This type of equipment automates the cigarette production process, improving production efficiency and product quality. Features of the Zj119 cigarette rolling machine may include high speed, stability, ease of operation and maintenance, etc. The Zj119 cigarette rolling machine is equipped with an air separation system, which is an important component of the Zj119 cigarette rolling machine and is mainly used for screening and sorting tobacco raw materials during the cigarette production process.
[0003] However, in actual use, the Zj119 cigarette rolling machine retains qualified tobacco stems after screening and sorting the tobacco raw materials, while removing other internal impurities. However, in actual use, it is impossible to quantitatively transport the screened tobacco stems, nor can it weigh them. This makes it impossible to control the specific amount during the transport process, which reduces the effectiveness of the device. Therefore, it is necessary to solve the above problems.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figures 1-4 A Zj119 cigarette machine's air-separation weighing device includes a support frame 1, a base 4 at the bottom of the support frame 1, and limit posts 41 vertically fixedly connected to the four corners of the top of the base 4. The four limit posts 41 slide vertically inside the bottom of the support frame 1. A pressure sensor 42 is installed at the center of the top of the base 4. The support frame 1 is fixedly installed on the top of the pressure sensor 42. A conveying roller 2 is rotatably connected inside the support frame 1. A rotating mechanism for rotating the conveying roller 2 is provided on the surface of the support frame 1. A guide plate 11 is fixedly connected to one side of the surface of the support frame 1. Side plates 12 are fixedly connected to both sides of the top of the guide plate 11. The guide plate 11 is set on the surface of the conveying roller 2. The ratchet 23 facilitates the rotation of the conveying roller 2 during use. At the same time, the pressure sensor 42 allows the conveying roller 2 to rotate at a certain angle after a certain amount of tobacco stems are loaded into the guide trough 21, so that a certain amount of tobacco stem material can be conveyed each time it rotates.
[0021] Reference Figure 2 and Figure 3 In a preferred embodiment, the rotating mechanism includes a ratchet 23. Multiple guide grooves 21 are provided on the surface of the conveying roller 2, and these grooves are evenly distributed in a ring on the surface of the conveying roller 2. A rotating shaft 22 is sleeved at the center of the conveying roller 2. The two ends of the rotating shaft 22 are respectively sleeved on opposite sides inside the support frame 1. The ratchet 23 is rotatably connected to one side of the surface of the support frame 1 and fixedly connected to one end of the rotating shaft 22. A second fixing post 24 is fixedly connected at the center of the surface of the ratchet 23. A second fixing plate 25 is fixedly connected to one end of the second fixing post 24. A connecting rod 3 is rotatably connected to the surface of the ratchet 23. The top end of the connecting rod 3 is sleeved on the surface of the second fixing post 24. A first torsion spring 31 is provided on the surface of the second fixing post 24. The two ends of the first torsion spring 31 are respectively fixedly connected to the surfaces of the connecting rod 3 and the second fixing plate 25 to restrict the rotation of the connecting rod 3, thus simultaneously restricting the rotation of the conveying roller 2.
[0022] Reference Figure 3 and Figure 4 In a preferred embodiment, a third fixing post 33 is fixedly connected to the surface of the connecting rod 3, and a third fixing plate 34 is fixedly connected to one end of the third fixing post 33. A pawl 6 is sleeved on the surface of the third fixing post 33, and the pawl 6 cooperates with the ratchet 23. A third torsion spring 61 is provided on the surface of the third fixing post 33, and the two ends of the third torsion spring 61 are fixedly connected to the pawl 6 and the surface of the connecting rod 3, respectively. A first fixing post 15 is fixedly connected to the side of the support frame 1 near the ratchet 23, and a first fixing plate 16 is fixedly connected to one end of the first fixing post 15. A limiting pawl 5 is sleeved on the surface of the first fixing post 15, and the limiting pawl 5 cooperates with the ratchet 23. A second torsion spring 51 is provided on the surface of the first fixing post 15, and the two ends of the second torsion spring 51 are fixedly connected to the limiting pawl 5 and the surface of the first fixing plate 16, respectively, to restrict the rotation of the conveying roller 2 so that the conveying roller 2 can only rotate in one direction.
[0023] Reference Figure 1 and Figure 4 In a preferred embodiment, a support column 13 is fixedly connected to the surface of the base 4, and an electric push rod 7 is installed on the top of the support column 13. A slot 32 is opened on the surface of the connecting rod 3, and the output end of the electric push rod 7 is located on the surface of the slot 32. A baffle 14 is fixedly connected to the side of the support frame 1 near the ratchet 23. The baffle 14 is located on the bottom side of the connecting rod 3 and is used to extend and retract the electric push rod 7, which will drive the connecting rod 3 to rotate.
[0024] From the above description, it can be seen that the above-described embodiments of this utility model achieve the following technical effects: In actual use, the ratchet 23 facilitates the rotation of the conveying roller 2. Simultaneously, the pressure sensor 42 allows the conveying roller 2 to rotate at a certain angle after a certain amount of tobacco stems are loaded into the guide trough 21, ensuring that a certain amount of tobacco stem material is conveyed with each rotation. When in use, this device can be installed at one end of an air classifier. After the air classifier conveys the tobacco stems, they will fall into the guide trough 21 on the surface of the conveying roller 2. Then, the limiting post 41 at the bottom of the support frame 1 will weigh the loaded tobacco stems. When the preset weight is reached, the weighing signal will be transmitted to... The internal control system drives the electric push rod 7 to extend and retract. When the electric push rod 7 extends, it drives the connecting rod 3 to rotate. With the pawl 6 in place, the ratchet 23 rotates, which in turn drives the conveying roller 2 to rotate, thus rotating and conveying a certain amount of weighed tobacco stems. The tobacco stems are then conveyed through the guide plate 11 on the surface of the support frame 1 and received through another guide trough 21. Then, the first torsion spring 31 causes the connecting rod 3 to rotate back to its original position. At the same time, the ratchet 23 is restricted from rotating under the constraint of the limiting pawl 5. This operation can continue in this manner, thereby enabling the weighing of tobacco stems during conveying and improving the efficiency of the device.
