Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cigarette packing detection, in particular to a cigarette pack separation device. Background Art
[0002] In the production and logistics links of the tobacco industry, it is often necessary to count, inspect, and package cigarette cartons. Cigarette cartons are often continuous during the transportation process. In the quality inspection link of cigarette cartons, if the cigarette cartons cannot be accurately separated, it will be difficult to conduct a comprehensive and detailed inspection of each cigarette, which may cause cigarette cartons with quality problems to enter the market and be difficult to directly handle individually.
[0003] The existing technology mainly uses a brush device, which uses the brush to create positive pressure on the cigarette strips. When the cigarette strips enter under the brush, they are decelerated by the positive pressure of the brush. After the cigarette strips leave the brush device, they are transported at a normal speed under the drive of the conveyor belt. However, during the transportation of the cigarette strips, the bristles of the brush easily absorb dust, tobacco and other impurities. If they are not cleaned in time, these impurities will accumulate on the brush, forming nodules on the brush, causing the bristles to harden, reducing the flexibility of the brush, and may even scratch the packaging of the cigarette strips, affecting the performance of the brush and the separation effect of the cigarette strips. In addition, the brush needs to constantly contact and rub with the cigarette strips during operation, and the brush will gradually wear out. After long-term use, the length of the brush becomes shorter and the density decreases, resulting in a decrease in the separation effect of the brush, and the brush needs to be replaced regularly.
[0004] Therefore, there is an urgent need for a cigarette strip separation device to solve the above problems. Utility Model Content

[0037] like Figure 1-Figure 3 As shown, in this embodiment, the cigarette strip separation device is arranged on the conveyor belt, and the conveyor belt is used to convey cigarette strips. The cigarette strip separation device includes a bracket 1, a driving mechanism 2 and a separation component 3. Among them, the bracket 1 is mounted on the conveyor belt, and the driving mechanism 2 includes a motor 21 and a transmission shaft 22. The motor 21 is arranged on the bracket 1, and the output end of the motor 21 is connected to the transmission shaft 22. The transmission shaft 22 is located below the conveyor belt, and the transmission shaft 22 is rotatably arranged on the bracket 1. The separation component 3 includes a first roller 31 and a second roller 32. The first roller 31 is sleeved on the transmission shaft 22. Along the height direction of the bracket 1, the highest point of the first roller 31 is higher than the working surface of the conveyor belt, and the rotation speed of the first roller 31 is greater than the conveying speed of the conveyor belt. The second roller 32 is located above the first roller 31, and the second roller 32 is rotatably arranged on the bracket 1. The second roller 32 can press against the cigarette strips on the conveyor belt.
[0038] Specifically, the cigarette strip separation device consists of a bracket 1, rollers, and a drive mechanism 2. It has a simple structure, and the equipment is easy to manufacture, install, and maintain. It also has high reliability and stability. The bracket 1 is a U-shaped structure, and the bracket 1 is semi-enclosed and mounted on the bottom and both sides of the conveyor belt. The motor 21 is mounted on one side of the bracket 1 through the base, and the output end of the motor 21 is connected to the transmission shaft 22. The transmission shaft 22 is rotatably passed through both sides of the bracket 1, and the transmission shaft 22 is located below the bottom of the conveyor belt. A first roller 31 is fixedly sleeved on the transmission shaft 22, and the second roller 32 is rotatably connected to the side wall of the bracket 1, and the second roller 32 is located above the first roller 31 and the conveyor belt. The first roller 31 and the second roller 32 are both made of soft rubber or polyurethane material, and have a certain degree of flexibility when in contact with the cigarette strips. This flexible contact can reduce damage to the cigarette packaging and protect the appearance quality and internal structure of the cigarette strips. In addition, the movement of the rollers is relatively stable, and the contact area with the cigarette strips is small, so it is not easy to malfunction during operation. The separation components 3 are all in rolling contact with the cigarette strips, which can reduce the friction between the cigarette strips and the separation device, reduce the wear and heat generated by friction, and help to extend the service life of the cigarette strips and improve the quality and stability of the product. Optionally, by adjusting the rotation speed of the first roller 31, it is easy to adapt to different cigarette strip conveying speeds. Whether it is high-speed conveying or low-speed conveying, the first roller 31 can effectively perform the separation operation, improving the versatility and adaptability of the equipment. Optionally, the size of the first roller 31 and the spacing between it and the second roller 32 can be precisely adjusted according to the specifications of the cigarette strips, thereby achieving precise control of the separation of the cigarette strips, helping to ensure that there is a suitable spacing between the separated cigarette strips, and facilitating subsequent processing and packaging operations.
[0039] The cigarette strip separation device operates as follows: Continuous cigarette strips or packs are conveyed on the conveyor belt. The motor 21 is activated, and the drive shaft 22 rotates in the same direction as the conveyor belt under the drive of the motor 21. The drive shaft 22 drives the first roller 31 to rotate synchronously. When the first cigarette strip on the conveyor belt passes the first roller 31, the first roller 31 and the second roller 32 simultaneously roll and rub against the cigarette strip, and the second roller 32 presses the cigarette strip against the first roller 31. The highest point of the first roller 31 is higher than the working surface of the conveyor belt. In addition, the rotation speed of the first roller 31 is greater than the conveying speed of the conveyor belt. During the contact process, the speed of the cigarette strip relative to the conveyor belt can be changed, causing the first cigarette strip passing through the separation assembly 3 to suddenly accelerate and separate from the second cigarette strip. In other words, driven by the first roller 31 and under the pressure of the second roller 32, the continuously conveyed cigarette strips are separated one by one. The efficient operation of the separation assembly 3 can meet the needs of large-scale cigarette strip separation and ensure the continuity and efficiency of production. The rotation of the second roller 32 can apply a certain pressure and friction to the cigarettes, effectively preventing the cigarettes from overlapping during transportation, which not only improves the accuracy of separation, but also reduces equipment failures and production delays caused by overlapping cigarettes.
[0040] Further, continue to refer to Figure 1-Figure 3 The cigarette strip separation device also includes an adjusting member 4, which includes a connecting portion 41 and a supporting portion 42. The supporting portion 42 is rotatably sleeved with a second roller 32. The connecting portion 41 is provided on the bracket 1, and the connecting portion 41 is eccentrically arranged relative to the central axis of the supporting portion 42. Specifically, the central axis of the connecting portion 41 does not coincide with the central axis of the supporting portion 42. The bracket 1 is provided with a threaded hole 121, and the outer periphery of the connecting portion 41 is provided with an external thread. The connecting portion 41 is threadedly connected to the threaded hole 121. According to the thickness of different cigarette strips, the adjusting member 4 is rotated, the connecting portion 41 rotates relative to the bracket 1, and the supporting portion 42 rotates around the central axis of the connecting portion 41 to adjust the spacing between the first roller 31 and the second roller 32, which helps to ensure that there is a suitable spacing between the separated cigarette strips, facilitating subsequent processing and packaging operations.
[0041] Further, continue to refer to Figure 1-Figure 2The bracket 1 includes a base 11 and two vertical plates 12. The base 11 is located below the conveyor belt. The two vertical plates 12 are respectively arranged at the two ends of the base 11, and a transmission shaft 22 is rotatably arranged between the two vertical plates 12. There are two separation components 3. The two first rollers 31 are respectively located on both sides of the conveyor belt, and the two second rollers 32 are respectively rotatably arranged on the corresponding vertical plates 12. Specifically, the two vertical plates 12 and the base 11 are combined into a U-shaped bracket 1, which is semi-enclosed and mounted on the bottom and both sides of the conveyor belt, that is, the base 11 is located below the conveyor belt, and the two vertical plates 12 are located beside the conveyor belt. When there is a need to separate the cigarette strips on the conveyor belt on the production line, the cigarette strip separation device also includes a fixed plate 5. The fixed plate 5 is arranged on the base 11, and the fixed plate 5 is installed on the fixed frame of the conveyor belt. The bracket 1 is mounted on the conveyor belt through the fixed plate 5, and the cigarette strips are separated by the driving mechanism 2 and the separation component 3.
[0042] Further, continue to refer to Figure 1-Figure 2 The cigarette strip separation device also includes a connecting member 6, a mounting hole 51 is provided on the fixed plate 5, and an adjustment hole 111 is provided on the base 11. The adjustment hole 111 is a waist-shaped structure, and the connecting member 6 passes through the adjustment hole 111 and is connected to the mounting hole 51. Specifically, the connecting member 6 is a bolt, and the fixed plate 5 is installed on the base 11 through the connecting member 6. There are two fixed plates 5, and the two fixed plates 5 are respectively arranged on both sides of the conveyor belt, and the two fixed plates 5 are respectively installed on both sides of the fixed frame of the conveyor belt. The connecting member 6 can be freely adjusted along the extension direction of the adjustment hole 111 to adjust the distance between the two fixed plates 5, so that it can be installed on conveyor belts of different widths, and has a wide range of applications.
[0043] Further, continue to refer to Figure 1-Figure 2 The central axis of the second roller 32 is arranged parallel to the central axis of the transmission shaft 22. Specifically, when the first cigarette on the conveyor belt passes through the first roller 31, the first roller 31 and the second roller 32 simultaneously roll and rub against the cigarette, and the second roller 32 presses the cigarette against the first roller 31. The first roller 31, the second roller 32 and the transmission shaft 22 are arranged parallel to each other, which can ensure that the cigarette will not deviate relative to the conveyor belt, ensuring the continuity and stability of cigarette transportation.
[0044] Further, continue to refer to Figure 1-Figure 2The cigarette strip separation device further includes a detection mechanism, which includes a detection sensor 7 and a control circuit board electrically connected to the detection sensor 7. The detection sensor 7 is disposed on the bracket 1 and is used to detect whether there are cigarette strips on the conveyor belt. The control circuit board is used to control the motor 21 to turn on or off. Specifically, when the detection sensor 7 detects that there are no cigarette strips on the conveyor belt, the detection sensor 7 sends a low level to the control circuit board, which controls the motor 21 to be in an off state, eliminating the need for cigarette strip separation. When the detection sensor 7 detects that a cigarette is being transported on the conveyor belt, the detection sensor 7 sends a high level to the control circuit board. The control circuit board can control the motor 21 to turn on. The transmission shaft 22 rotates in the same direction of the conveyor belt under the driving action of the motor 21. The transmission shaft 22 drives the first roller 31 to rotate synchronously. The first roller 31 and the second roller 32 simultaneously roll and rub against the cigarette. The second roller 32 presses the cigarette against the first roller 31. Driven by the first roller 31 and under the pressure of the second roller 32, the continuously transported cigarettes are separated one by one. The efficient operation of the separation component 3 can meet the needs of large-scale cigarette separation and ensure the continuity and efficiency of production. The detection mechanism realizes linkage control and automated production with other production links, improving the efficiency of cigarette production and transportation stability.
[0045] Further, continue to refer to Figure 1-Figure 2 The cigarette carton separation device also includes an alarm, which is mounted on the bracket 1 and electrically connected to the control circuit board. Specifically, when the detection sensor 7 detects that cigarette carton is being transported on the conveyor belt and the motor 21 is not running, the cigarette carton separation device has a fault and sends a high level signal to the control circuit board. The control circuit board can control the alarm to sound an alarm and perform fault self-diagnosis to help operators quickly locate and eliminate the fault, thereby reducing production losses.
