Description

Technical Field

[0001] This utility model relates to the field of cigarette production equipment technology, and in particular to a device that can perform tobacco stem sampling and blockage detection. Background Technology

[0002] The cigarette making machine is a high-speed operating device used in cigarette production. During the cigarette production process, if the tobacco shreds contain an abnormal proportion of tobacco stems, it will lead to quality defects such as punctures and uneven circumference in the cigarettes. Therefore, it is necessary to remove some of the tobacco stems from the tobacco shreds and collect them centrally. At the same time, a tobacco stem sampling device is needed to sample the removed tobacco stems to analyze their quality and composition, ensuring the production quality of the cigarettes. The existing tobacco stem sampling device uses negative pressure to input tobacco stems into a negative pressure pipeline. The negative pressure pipeline is equipped with a three-way reversing valve. One end of the reversing valve can input tobacco stems into a centralized dust collection device, while the other end uses a centrifugal separator to throw the tobacco stems into a sampling box. The negative pressure air is then input into the centralized dust collection device through another pipeline inside the sampling box. This device has a very complex structure, requiring multiple negative pressure pipelines and a centrifugal separator. It is bulky, and the sampling device part can only be arranged on the outside of the machine body, which cannot meet the requirements of miniaturization and aesthetic design of new cigarette equipment.

[0003] In summary, developing a device with a simple structure and small size that can perform tobacco stem sampling and blockage detection is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] This application provides a device for tobacco stem sampling and blockage detection. The device includes a support 3, with a collection hopper 1 connected to one end of the support 3. The collection hopper 1 receives falling tobacco stems and guides them to its opening. A rotating pipe 6 is provided on one side of the collection hopper 1's opening, rotatably connected to the side wall of the support 3. A connecting pipe 61 is provided on the side wall of the rotating pipe 6, which connects to the opening of the collection hopper 1. Tobacco stems entering the collection hopper 1 pass through the opening and the connecting pipe 61 into the rotating pipe 6. A negative pressure pipe 5 is connected to the end of the rotating pipe 6 facing away from the opening of the collection hopper 1, transporting the tobacco stems inside the rotating pipe 6. Additionally, a sampling box is provided below the collection hopper 1. 8. The port of the sampling box 8 corresponds to the opening of the collection hopper 1. The tobacco stems in the collection hopper 1 can fall into the sampling box 8 through the opening of the collection hopper 1. In one embodiment of this application, the transportation and sampling functions of the device for tobacco stem sampling and blockage detection can be switched by rotating the rotating pipe 6. The connecting pipe 61 of the rotating pipe 6 is connected to the opening of the collection hopper 1. At this time, the device for tobacco stem sampling and blockage detection can be in the transportation state. The tobacco stems enter the rotating pipe 6 and are sucked away by the negative pressure pipe 5. The connecting pipe 61 of the rotating pipe 6 is completely separated from the opening of the collection hopper 1. The port of the collection hopper 1 is connected to the sampling box 8. The tobacco stems pass through the opening of the collection hopper 1 and fall into the sampling box 8. After sampling is completed, the sampling box 8 can be taken out. The rotating pipe 6 is rotated again to reset the rotating pipe 6 and continue to transport tobacco stems.

[0026] Please refer to the instruction manual appendix. Figure 1A pipe rack 7 is provided on one side of the support 3, and the pipe rack 7 is perpendicular to the support 3. An installation groove (not shown in the figure) is provided at the end of the pipe rack 7 near the collection hopper 1. An installation flange 63 is provided at the end of the rotating pipe 6, which can be clamped and engaged in the installation groove. The installation flange 63 can rotate within the installation groove. Similarly, the rotating pipe 6 rotates around its center line with the installation flange 63. A rotating shaft 62 is provided at the end of the rotating pipe 6 away from the installation flange 63, and the extension direction of the rotating shaft 62 coincides with the axis of the rotating pipe 6. Preferably, a sealing block 2 is also provided at the end of the support 3. The sealing block 2 has a connecting hole 21 that can connect with the opening of the connecting pipe 61 and the collection hopper 1. The sealing block 2 connects the collection hopper 1 and the rotating pipe. 6. Connection ensures that the tobacco stems in the collection hopper 1 can smoothly enter the rotating pipe 6. An arc-shaped groove 22 is provided on the side of the sealing block 2 near the opening of the collection hopper 1. The connecting hole 21 passes through the arc-shaped sidewall of the arc-shaped groove 22. Correspondingly, an arc plate 64 is provided in the rotating pipe 6. The radius of the arc corresponding to the arc plate 64 is larger than the radius of the rotating pipe 6. The arc plate 64 fits into the connecting pipe 61. The connecting pipe 61 extends along the thickness direction of the arc plate 64 to pass through the arc plate 64. In the process of transporting tobacco stems, the rotating pipe 6 is rotated. The rotating pipe 6 drives the arc plate 64, so that the arc plate 64 gradually fits into the sidewall of the arc-shaped groove 22 of the sealing block 2. The rotating pipe 6 connects with the connecting hole 21 of the sealing block 2.

[0027] It should be noted that the mounting flange 63 consists of two parallel flanges with a distance between them slightly greater than the thickness of the pipe rack 7. Each flange clamps the rotating pipe 6 onto the side wall of the pipe rack 7, and the mounting groove fits snugly against the side wall of the rotating pipe 6 to ensure the smooth rotation of the rotating pipe 6.

[0028] Preferably, the curvature of the arc plate 64 is the same as that of the arc groove 22, but the radius of the arc plate 64 is slightly larger than the radius of the arc of the arc groove 22. That is, during the process of the arc plate 64 and the arc groove 22 fitting together, the arc plate 64 bends towards the side closer to the center of the arc of the arc groove 22. When the arc plate 64 and the arc groove 22 are fully fitted together, the arc plate 64 holds the side wall of the arc groove 22 with elasticity, so that the two fit tightly together, ensuring the tightness of the connection between the collection hopper 1 and the rotating pipe 6.

[0029] Please refer to the instruction manual appendix. Figure 1 With appendix Figure 3Both the support 3 and the pipe frame 7 are specifically bent plates with a bending angle of 90°. The height of the support 3 is greater than the height of the pipe frame 7. A sealing block 2 is fixedly connected to the side wall of the support 3. The width of the sealing block 2 is less than the width of the sampling box 8. The side wall of the sampling box 8 fits against the side wall of the support 3. That is, the arc groove 22 at the end of the sealing block 2 is spaced apart from the side wall of the sampling box 8 away from the support 3. After the device that can realize tobacco stem sampling and blockage detection is converted to tobacco stem sampling mode, the rotating pipe 6 rotates to the side away from the sealing block 2. At this time, the two sides of the arc plate 64 respectively The rotating pipe 6 connects to the outside through the connecting pipe 61 of the rotating pipe 6 and the edge of the sealing block 2 and the edge of the sampling box 8. The negative pressure pipe 5 cannot transport the tobacco stems in the collection hopper 1 to the dust removal equipment. In addition, at this time, the arc plate 64 and the arc groove 22 have no fitting part, which prevents the connecting pipe 61 from separating from the connecting hole 21. The arc plate 64 partially blocks the connecting pipe 61, and the opening of the collection hopper 1 is blocked. Furthermore, the arc plate 64 connects the sampling box 8 and the sealing block 2, which blocks the notch on one side of the opening of the collection hopper 1, preventing some tobacco stems from falling outside the sampling box 8 during the sampling process.

[0030] Please refer to the instruction manual appendix. Figure 2 The collecting hopper 1 is fixed to the end face of the sealing block 2 away from the arc groove 22. The opening of the collecting hopper 1 is aligned with the connecting hole 21 of the sealing block 2. The inner cavity of the collecting hopper 1 gradually narrows towards the end close to the sealing block 2, forming a tapering slope. When the tobacco stem enters the collecting hopper 1, it slides through the tapering slope to the opening of the collecting hopper 1, ensuring that the tobacco stem can quickly enter the rotating pipe 6 or the sampling box 8. In addition, a detection plate 10 is provided at the end of the collecting hopper 1 away from the opening. The detection plate 10 is specifically a bent plate with a bending angle of 90°. The extension direction of the bent part is parallel to the end face of the sealing block 2. The end of the bent plate corresponds to the opening of the collecting hopper 1. A sensor 9 is inserted through the end of the detection plate 10. Preferably, the sensor 9 is a distance sensor. The sensor 9 detects the distance between the tobacco stem in the collecting hopper 1 and the sensor 9. The sensor 9 is also connected to an alarm. If the distance between the sensor 9 and the tobacco stem is less than a preset distance, the sensor 9 sends a blockage signal and the alarm is activated.

[0031] Preferably, the rotating shaft 62 of the rotating pipe 6 extends out of the outer end of the sampling box 8. The end of the rotating shaft 62 can be connected to any one of the handle 4, motor shaft, or cylinder shaft. When switching the mode of the device that can realize tobacco stem sampling and blockage detection, the rotating pipe 6 can be rotated by pulling the handle 4 or starting the motor. A negative pressure pipe 5 is connected to the side of the rotating pipe 6 away from the rotating shaft 62. The other end of the negative pressure pipe 5 is connected to a dust removal device, which provides negative pressure to the negative pressure pipe 5.

[0032] Please refer to the instruction manual appendix. Figure 4At this time, the device for tobacco stem sampling and blockage detection is in tobacco stem transport mode. The arc-shaped plate of the rotating pipe 6 is in contact with the side wall of the arc-shaped groove 22 of the sealing block 2. The connecting pipe 61 of the rotating pipe 6 is connected to the connecting hole 21. The tobacco stem falls from above the collecting hopper 1 onto the tapering inclined surface. The tobacco stem slides down the tapering inclined surface to the opening of the collecting hopper 1. The dust removal device forms a negative pressure at the port of the collecting hopper 1 through the connected rotating pipe 6 and the sealing block 2. The tobacco stem at the port is sucked into the rotating pipe 6 and enters the dust removal equipment through the negative pressure pipe 5. Please refer to the instruction manual appendix. Figure 5 At this time, the device for tobacco stem sampling and blockage detection is in sampling mode. The connecting pipe 61 of the rotating pipe 6 is completely separated from the connecting hole 21 of the sealing block 2. The arc plate 64 is not in contact with the side wall of the arc groove 22. The collecting hopper 1 is connected to the inner cavity of the sampling box 8 through the connecting hole 21 of the sealing block 2. The tobacco stems fall into the sampling box 8 from the opening of the collecting hopper 1 by gravity. After a period of sampling, the rotating pipe 6 is rotated, and the device for tobacco stem sampling and blockage detection continues to operate in transport mode to test the collected tobacco stems and analyze their quality and composition.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
