Description

Technical Field

[0001] This invention belongs to the technical field of cigarette production equipment, specifically relating to an online tobacco additive detection device. Background Technology

[0002] Blending is an important step in cigarette production. The blending process refers to the process of uniformly and precisely mixing air-blown tobacco, expanded tobacco, stems, and recycled tobacco into the finished cigarette leaves according to the proportions set in the process formula. It is a key link to ensure that the content of various types of tobacco in cigarette products meets the process requirements, and the uniformity of blending directly determines the stability of the taste and smoking experience of the cigarette products.

[0003] In existing technologies, after blending is completed, the uniformity of the additives is checked. However, this is done by using an infrared detector to check the surface of the blended material. The uniformity in the thickness direction of the material cannot be detected. In the lower layer of the material, there may be uneven distribution of the material, such as clumping. It is impossible to detect and deal with the clumping in the lower layer of the material in a timely manner. Summary of the Invention

[0004] The purpose of this invention is to provide an online tobacco additive detection device to solve the problem that when using an infrared detector to detect the surface of the blended material, the uniformity in the thickness direction of the material cannot be detected, and uneven material distribution such as clumping may occur in the lower layer of the material, making it impossible to detect and deal with the clumping in the lower layer of the material in a timely manner.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] An online tobacco additive detection device includes a feed belt with a detection unit mounted on it. The detection unit is used to periodically detect the uniformity of the additives.

[0007] The feed belt outlet is connected to a guide chute, the guide chute is equipped with a uniformity adjustment component, and the guide chute outlet is connected to a blending belt.

[0008] The uniformity adjustment component includes several sliding plates, which are evenly arranged along the length of the feed chute, and adjacent sliding plates can vibrate horizontally in an alternating manner.

[0009] Preferably, the acquisition and detection unit includes a first photodetector and a cross-section detection component. The first photodetector and the detection component are respectively fixedly installed above the feed belt, with the first photodetector located in front of the cross-section detection component in the feeding direction of the feed belt. This configuration allows the first photodetector to detect the surface distribution of the material.

[0010] Preferably, the cross-section detection assembly includes a mounting base disposed above the feed belt, and a detection cavity is formed inside the mounting base, in which a second photoelectric detector is fixedly installed;

[0011] The mounting base has a sampling slot that communicates with the detection chamber. A first cylinder is fixedly installed inside the sampling slot, and a sampling clamp is driven to the telescopic end of the first cylinder. This configuration allows the sampling clamp to move via the telescopic movement of the first cylinder, gripping the material without altering its distribution on the feed belt. The distribution of the material in the thickness direction is then detected by a second photoelectric detector.

[0012] Preferably, a first limiting block and a second limiting block are fixedly connected in the sampling slot, the first limiting block is located below the second limiting block, and the sampling clamp is slidably disposed between the first limiting block and the second limiting block;

[0013] When the sampling clamp abuts against the first limiting block, the two clamping plates of the sampling clamp slide towards each other. When the sampling clamp abuts against the second limiting block, the two clamping plates of the sampling clamp slide away from each other. When the sampling clamp slides between the first and second limiting blocks, the relative position between the two clamping plates of the sampling clamp remains unchanged. With this configuration, the sampling clamp picks up material at the first limiting block, then the first cylinder drives the sampling clamp to the detection chamber for detection, and then drives the sampling clamp to the second limiting block, where the sampling clamp releases the material, and the material falls back onto the feed belt.

[0014] Preferably, each of the aforementioned slide plates is fixedly equipped with screening teeth. This arrangement allows the material to be screened by the screening teeth on the slide plates, thereby improving the uniformity of the material.

[0015] Preferably, an installation groove is provided in one side wall of the material guide groove along the length of the material guide groove, a drive rod is slidably installed in the installation groove, a third cylinder is provided in the installation groove, and the telescopic end of the third cylinder is fixedly connected to the drive rod.

[0016] The feed trough has several guide holes, and a guide rod is fixedly connected to the slide plate. The guide rod is slidably disposed in the guide holes. A protrusion corresponding to the slide plate is fixedly connected to the drive rod, and the front end of the guide rod abuts against the protrusion.

[0017] A reset assembly is provided between the slide plate and the guide chute. This configuration allows the first cylinder to be activated when material agglomeration is detected. The reciprocating motion of the cylinder's extension end drives the drive rod to slide up and down, with the guide rod's front end contacting different positions on the protrusion. This causes the slide plate to slide horizontally, causing the screening teeth to slide alternately, impacting the agglomerated material and dispersing it.

[0018] Preferably, the reset assembly includes a reset spring. A positioning hole is formed in the side wall of the guide groove away from the mounting groove. A positioning rod is fixed to the slide plate, the axis of which is parallel to the axis of the guide rod. The reset spring is sleeved on the positioning rod and located between the guide groove and the slide plate. This arrangement provides pressure to the slide plate towards the protrusion, allowing the guide rod to maintain contact with the protrusion and enabling the slide plate to slide back and forth.

[0019] Preferably, one end of the positioning rod extends through the side wall of the guide groove, a transmission gear is fixedly connected to the positioning rod, the axes of the positioning rod are all located in the same plane, a rack is fixedly connected to the side wall of the guide groove, and the length direction of the rack is parallel to the plane formed by the axes of the positioning rod, and the rack meshes with the transmission gear.

[0020] A fourth cylinder is fixedly installed on the outer wall of the feed chute, and the rack is fixed to the telescopic end of the fourth cylinder. This arrangement facilitates the flipping of the slide plates, and when the material falls from one slide plate to the next, it is subjected to the impact of gravity, which improves the de-agglomeration effect.

[0021] Preferably, a telescopic baffle is provided on the upper surface of the slide plate, a rubber strip is provided on the top of the telescopic baffle, and a placement groove matching the rubber strip is provided on the lower surface of the telescopic baffle. This arrangement helps to close the rear end gap when the slide plates are flipped, preventing materials from falling through the gap between the slide plates and reducing material waste.

[0022] Preferably, both the first and second photodetectors are connected to a processor. This configuration facilitates online monitoring of materials on the production line, allows for timely control when abnormal material distribution occurs, and improves production efficiency.

[0023] Because of the adoption of the above technical solution, the present invention has the following advantages:

[0024] 1. In the solution, the uniformity of tobacco material during feeding is detected by the acquisition and detection unit. When uneven distribution such as clumping is detected in the tobacco material, the uniformity adjustment component set on the feed chute is used to adjust the uniformity of the material in time, so that the material has good uniformity and more uniform distribution, thereby improving product quality.

[0025] 2. In this solution, when tobacco material clumps together, the third cylinder is activated, causing the extension end of the third cylinder to reciprocate, which drives the drive rod to slide up and down. The front end of the guide rod contacts different positions on the protrusion, causing the slide plate to slide horizontally, which drives the screening teeth to slide alternately, simulating the vibration effect, which has an impact effect on the clumped material, dispersing the material and reducing the clumping in the material.

[0026] 3. In this solution, by setting the slide plates to a flip-type structure, when tobacco material clumps together, the slide plates flip each other. When the material falls from one slide plate to the next, it is subjected to the impact of gravity, which, combined with the unclogging action of the slide plates sliding alternately, improves the unclogging effect.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0042] like Figures 1 to 7 As shown, an online tobacco additive detection device of the present invention includes a feed belt 1, on which a collection and detection unit is provided. The detection unit is used to periodically detect the uniformity of the additives.

[0043] The discharge port of the feed belt 1 is connected to the guide chute 2, the guide chute 2 is equipped with a uniformity adjustment component, and the discharge port of the guide chute 2 is connected to the mixing belt.

[0044] In this embodiment, the acquisition and detection unit includes a first photoelectric detector 3 and a cross-section detection component. The first photoelectric detector 3 and the cross-section detection component are respectively fixedly installed above the feed belt 1. The first photoelectric detector 3 is located in front of the detection component in the feeding direction of the feed belt 1. The material distribution on the surface of the material flow is detected by the first photoelectric detector 3.

[0045] The detection assembly includes a mounting base 4, which is fixedly installed above the feed belt 1. A detection cavity 41 is provided on the lower end face of the mounting base 4, and a second photoelectric detector 411 is fixedly installed in the detection cavity 41. A sampling slot 42 is provided on the mounting base 4, which communicates with the detection cavity 41. A first cylinder 44 is fixedly installed in the sampling slot 42, and the telescopic end of the first cylinder 44 is connected to the sampling clamp 421.

[0046] Both the first photodetector 3 and the second photodetector 4 are connected to a processor, which is connected to a communication network to detect silk additives online.

[0047] The sampling clamp 421 includes two clamping plates 4211 and a mounting horizontal plate 4212. The two clamping plates 4211 are slidably disposed below the mounting horizontal plate 4212. The telescopic end of the first cylinder 44 slides vertically through the mounting horizontal plate 4212. The mounting horizontal plate 4212 has movable grooves 4213 that match the two clamping plates 4211 respectively. A connecting shaft 4214 is slidably disposed in the movable groove 4213. The two ends of the connecting shaft 4214 are rotatably connected to the clamping plates 4211. A connecting rod 4215 is connected to the middle of the connecting shaft 4214. The connecting rod 4215 is rotatably connected to the telescopic end of the first cylinder 44.

[0048] Understandably, the clamp plate 4211 on the side of the sampling clamp 421 closest to the detection chamber 41 is a transparent plate, which facilitates the second photodetector to perform detection through the clamp plate 4211.

[0049] The sampling clamp 421 is moved down to the feed belt by the first cylinder to clamp the material, which is beneficial to clamp the material without changing the distribution state of the material in the material flow and to detect the distribution of the material in the thickness direction.

[0050] A limiting groove is provided at one end of the movable slide 4213 near the first cylinder 44, and an arc-shaped baffle 4217 is provided in the limiting groove. A first limiting block 422 and a second limiting block 423 are provided in the sampling groove. Both the first limiting block 422 and the second limiting block 423 are located on the stroke of the mounting plate 4212, and the second limiting block 423 is located above the first limiting block 422.

[0051] The first cylinder drives the sampling clamp 421 to move down to the first limiting block 422. The first limiting block 422 limits the mounting plate 4212. The telescopic end of the first cylinder continues to move down, driving the connecting rod 4215 to rotate, causing the connecting shaft 4214 to approach between the movable slide grooves 4213 until it slides into the limiting slot. The two clamping plates 4211 clamp the material. Then the first cylinder 44 retracts its telescopic end. The connecting shaft 4214 is located in the limiting slot and is blocked by the arc-shaped baffle 4217. The sampling clamp 421 picks up the material and rises together to the detection chamber for detection. After reaching the position of the second limiting block 423, the mounting plate 4212 is blocked by the second limiting block 423 during the rise. The telescopic end of the first cylinder applies a force along the axial direction of the connecting rod 4215 to the connecting shaft 4214 through the connecting rod 4215. The connecting shaft 4214 disengages from the limiting slot, and the two clamping plates 4211 release the material.

[0052] This causes the two clamping plates 4211 of the sampling clamp 421 to slide towards each other when the sampling clamp 421 comes into contact with the first limiting block 422, and the two clamping plates 4211 of the sampling clamp 421 to slide away from each other when the sampling clamp 421 comes into contact with the second limiting block 423. When the sampling clamp 421 slides between the first limiting block 422 and the second limiting block 423, the relative position between the two clamping plates 4211 of the sampling clamp 421 remains unchanged.

[0053] Understandably, in other embodiments of this application, the sampling clamp 421 may also be a robotic arm connected to the first cylinder 44. The first cylinder 44 drives the robotic arm to move down and grab the material from the feed belt 1. Then the first cylinder moves up and carries the grabbed material to the detection chamber 41 for detection.

[0054] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the uniformity adjustment component includes several sliding plates 5, which are evenly distributed along the length of the feed chute 2, and each of the sliding plates 5 is fixed with screening teeth 51. The screening teeth 51 on the sliding plates 5 screen the material, thereby improving the uniformity of the material.

[0055] In this embodiment, an installation groove 21 is provided in the inner side wall of the material guide trough 2 along the length direction of the material guide trough 2. A drive rod 22 is slidably installed in the installation groove 21. A third cylinder 23 is provided in the installation groove 21. The telescopic end of the third cylinder 23 is fixedly connected to the drive rod 22.

[0056] The feed chute 2 has several guide holes, and a guide rod 24 is fixedly connected to the slide plate 5. The guide rod 24 is slidably disposed within the guide holes. A protrusion 221 corresponding to the slide plate 5 is fixedly connected to the drive rod 22. The protrusions 221 are arranged along the length direction of the drive rod 22, and the spacing between the protrusions 221 is different. The front end of the guide rod 24 abuts against the protrusion 221. Understandably, in order to extend the service life of the equipment, the front end of the guide rod 24 is set as an arc-shaped block, and the position on the protrusion 221 that contacts the front end of the guide rod 24 is set as an arc-shaped structure to reduce friction.

[0057] The third cylinder 23 starts and drives the drive rod 22 to slide. The guide rods 24 on different slide plates 5 have different contact positions with the corresponding protrusions 221 on the drive rod 22. At this time, the slide plates 5 slide alternately, which drives the screening teeth 51 to slide alternately, which has an impact effect on the agglomerated materials and disperses the materials.

[0058] In this embodiment, a reset assembly is provided between the slide plate 5 and the guide groove 2. The reset assembly includes a reset spring 26. A positioning hole is provided in the side wall of the guide groove 2 away from the mounting groove 21. A positioning rod 25 is fixedly connected to the slide plate 5. The axis of the positioning rod 25 is parallel to the axis of the guide rod 24. The reset spring 26 is sleeved on the positioning rod 25, and its two ends abut against the guide groove 2 and the slide plate 5. The reset spring 26 provides pressure on the slide plate 5 toward the protrusion 221, so that the guide rod 24 can maintain an abutment state with the protrusion 221, allowing the slide plate 5 to slide back and forth. In other embodiments of this application, the reset assembly can also be a rubber sleeve sleeved on the positioning rod 25, with its two ends abutting against the guide groove 2 and the slide plate 5, providing pressure on the slide plate 5 toward the protrusion 221, so that the guide rod 24 can maintain an abutment state with the protrusion 221, allowing the slide plate 5 to slide back and forth.

[0059] When tobacco material clumps together, the third cylinder 23 is activated, causing the extension end of the third cylinder 23 to reciprocate, which drives the drive rod 22 to slide up and down. The front end of the guide rod 24 contacts different positions on the protrusion 221, causing the slide plate 5 to slide horizontally, which in turn causes the screening teeth 51 to slide alternately, thus impacting the clumped material, dispersing the material and reducing clumping.

[0060] In this embodiment, one end of the positioning rod 25 extends through the side wall of the guide groove 2, and a transmission gear 27 is fixedly connected to the positioning rod 25. The axes of the positioning rod 25 are all located in the same plane. A rack 28 is fixedly connected to the side wall of the guide groove 2, and the length direction of the rack 28 is parallel to the plane formed by the axis of the positioning rod 25. The rack 28 meshes with the transmission gear 27.

[0061] A fourth cylinder 29 is fixedly installed on the outer wall of the feed chute 2, and a rack 28 is fixedly connected to the telescopic end of the fourth cylinder 29. The slide plates 5 are configured with a flipping structure. When tobacco material clumps together, the slide plates 5 flip each other. When the material falls from one slide plate 5 to the next, it is impacted by gravity, which, combined with the unclogging action of the slide plates 5 sliding alternately, improves the unclogging effect.

[0062] Understandably, a telescopic baffle 52 is provided on the upper surface of the slide plate 5, a rubber strip is provided on the top of the telescopic baffle 52, and a placement groove matching the rubber strip is provided on the lower surface of the telescopic baffle 52. When the slide plates 5 are flipped between each other, the rear end gap is closed to prevent materials from falling through the gap between the slide plates 5 and reduce material waste.

[0063] The principle of this application is as follows: the feed belt 1 transports the tobacco material, the first photoelectric detector 3 detects the surface of the material flow, and the first cylinder 44 drives the sampling clamp 421 to pick up the material from the feed belt 1. Before reaching the detection chamber, the second photoelectric detector 411 of the cross-section detection component detects the material distribution in the thickness direction. When the tobacco material clumps together, the third cylinder 23 is activated, causing the telescopic end of the third cylinder 23 to reciprocate, driving the drive rod 22 to slide up and down. The front end of the guide rod 24 contacts different positions on the protrusion 221, causing the slide plate 5 to slide horizontally, driving the screening teeth 51 to slide alternately, which has an impact effect on the clumped material, dispersing the material and reducing clumping. At the same time, the fourth cylinder 29 is activated, causing the slide plates 5 to flip back and forth. When the material falls from one slide plate 5 to the next, it is impacted by gravity, which, combined with the de-clumping action of the slide plates 5 sliding alternately, improves the de-clumping effect.

[0064] The above provides a detailed description of the online tobacco additive detection device provided by the present invention. The specific embodiments are described only to aid in understanding the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
