Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco manufacturing technology, and in particular to a tobacco stem transfer detection device. Background Technology
[0002] In the stem separation system, after the stems are separated by a two-stage air separation device, they fall directly into the collection funnel. The bottom of the funnel is connected to the stem conveying pipeline, which transports the stems to the stem recycling device. The pipeline system then sends the stems into the stem box or the central stem removal system.
[0003] However, while secondary air separation separates tobacco shreds from the stems or adjusts the stem density through airflow, whether the ratio of separated stem shreds (i.e., the residual proportion of tobacco shreds in the stems) meets the standards needs to be confirmed through subsequent processes. Directly feeding the stems into the funnel means that problems cannot be detected in the separation process immediately. This results in the stem shreds collected in the stem box needing to be returned to the stem separation system multiple times for reprocessing, increasing rework costs, extending the production cycle, reducing output per unit time, and impacting production efficiency. Summary of the Invention
[0004] To address the aforementioned technical problems, this utility model provides a stem transfer detection device that moves quality control forward to the air separation stage through real-time detection, thereby improving the controllability of the production process and the stability of product quality.
[0005] The technical solution adopted by this utility model to solve its technical problem is to provide a filament transfer detection device, comprising: The conveyor line is inclined upward at a specific angle to the horizontal plane and is used to transport the filaments from the bottom start end to the top end. The inspection mechanism includes an inspection camera assembly that is adjustable above the conveyor line via mounting components; A receiving hopper is located at the end of the conveyor line and includes a hopper body that is connected to the conveyor line and a receiving pipe located at the bottom of the hopper body.

[0007] As a further improvement of this utility model, the wire support is symmetrically provided with material separating belts on both sides along the wire conveying direction, and the two material separating belts are arranged opposite each other on the two side edges of the conveyor belt.
[0008] As a further improvement of this utility model, the mounting assembly includes: A support plate is provided on the side of the conveyor line and is vertically installed near the bottom of the conveyor line; The connecting frame is positioned above the conveyor line, perpendicular to the direction of the wire conveying. One end of the frame is movably connected to the support plate, and the other end is connected to a mounting plate for mounting the detection camera.
[0009] As a further improvement of this utility model, the detection camera assembly includes a controller and an industrial camera. The controller is fixedly installed on the side of the mounting plate facing the direction of the wire conveying, and the industrial camera is installed on the front side of the mounting plate through an adjustment bracket and is electrically connected to the controller.
[0010] As a further improvement of this utility model, the adjusting bracket includes: Two fixing plates are symmetrically arranged at both ends of the bottom of the mounting plate, and waist-shaped adjustment holes are provided on the two fixing plates; The first adjusting plate, and the two first adjusting plates are respectively rotatably connected to the corresponding fixed plates through a rotating shaft, and are locked and fixed by fasteners passing through the waist-shaped adjusting holes.
[0011] As a further improvement of this utility model, the adjustment bracket also includes a second adjustment plate, and the industrial camera is fixed on the second adjustment plate; the two ends of the second adjustment plate are respectively provided with vertically arranged connection slots corresponding to the connection positions of the two first adjustment plates, and fasteners are passed through the connection slots to lock and fix the first adjustment plate.

The horizontal portion is provided with a proximity switch for detecting the amount of filaments in the funnel body.
[0013] As a further improvement of this utility model, the bottom of the funnel body is provided with a hopper that connects to the receiving pipe. The hopper is provided with a stalk collector. The top opening of the stalk collector connects to the outlet of the funnel body. The stalk collector is provided with an outlet on the side facing the receiving pipe. The outlet extends to the outside of the hopper through a connecting pipe and is connected to the receiving pipe through a clamp-type quick connector.
[0014] As a further improvement of this utility model, a dust collection chamber is formed between the filament collector and the inner wall of the hopper, and a dust collection pipe interface communicating with the dust collection chamber is provided on the side wall of the hopper adjacent to the receiving pipe.

[0018] The preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0019] See Figure 1This utility model proposes a stem transfer detection device, which is arranged between the secondary air separation process of the stem separation system and the tobacco stem conveying pipeline. It is mainly used to monitor the stem content in tobacco stems in real time and feed back the stem ratio data to the stem separation system so as to make real-time adjustments to the secondary air separation process, thereby moving quality control forward to the air separation stage and improving the controllability of the production process and the stability of product quality.
[0020] The tobacco stem transfer and detection device includes a conveyor line 1, a detection mechanism 2 located on the conveying path of the conveyor line 1, and a collection funnel 3 located at the end of the conveyor line 1. The conveyor line 1 transports the tobacco stems from the feeding vibrating trough 4 (which outputs the tobacco stems separated in the secondary air separation process) to the funnel body 31 of the collection funnel 3. The stems then enter the tobacco stem conveying pipe through the collection pipe 32 at the bottom of the funnel body 31 for collection. Simultaneously, during the conveying process, the detection camera assembly 22 of the detection mechanism 2 takes pictures of the amount of tobacco in the stems to detect the tobacco stem ratio in real time after secondary air separation. The conveyor line 1 is arranged at a specific upward angle to prevent the accumulation of tobacco stems during conveying, thereby ensuring the accuracy and reliability of the sampling results.
[0021] It should be noted that the control program of the stalk transfer and detection device involved in this application is built based on the PLC program of an existing stalk separation system. In the device of this application, both the conveyor line and the detection mechanism have intelligent processing capabilities. Through the pre-set program of the stalk separation system, combined with the data obtained from real-time detection, they autonomously analyze and adjust their own action information. For example, they can flexibly adjust the conveying speed of the conveyor line and control the shooting frequency of the detection camera component according to actual needs. In addition, the application technology of industrial cameras in this field is relatively mature; therefore, the control system is not described in detail in this application.
[0022] See Figure 1 and 2 The conveyor line 1 includes a line support 11, a conveyor belt 12, and a drive mechanism 13. The line support 11 is inclined at an angle of 10° to 20° to the horizontal plane, balancing space utilization and conveying requirements. The conveyor belt 12 is wound around drive rollers and driven rollers on the line support 11, forming a stable conveying channel. The drive mechanism 13 is located at the end of the line support 11, and its function is to drive the drive rollers, thereby driving the conveyor belt 12. To ensure the accuracy and stability of the drive, a servo motor is used in the drive mechanism.
[0023] The preferred inclination angle of the conveyor line 1 is 15°. This allows for a compact and efficient installation within the limited space of the frame 5, while also maximizing the length of the conveyor belt within the confined space, creating favorable conditions for rapid filament transport. For example, in conjunction with the sampling speed of an industrial camera, the conveyor belt can stably transport filaments at a speed of 1 m / s, effectively improving sampling and testing efficiency.
[0024] Furthermore, the conveyor belt 11 is symmetrically equipped with two material separating belts 14 on both sides along the direction of wire conveying. The two material separating belts 14 are arranged opposite each other at the two side edges of the conveyor belt 12. This effectively prevents the wire from spreading to both sides and falling off during the conveying process, or from falling into the conveyor support, thereby ensuring the stability of wire conveying and reducing material loss and equipment failure risk.
[0025] The material separator belt is made of soft materials such as food-grade rubber, which is flexible and will not interfere with the conveyor belt's conveying speed, ensuring that the conveyor belt can operate stably according to preset parameters and reducing equipment maintenance costs.
[0026] Continue reading Figure 1 and Figure 3 The detection camera assembly 22 of the detection mechanism 2 is mounted on the conveyor line 1 via the mounting assembly 21, so that the detection camera assembly 22 has the ability to be flexibly adjusted in multiple directions and angles, thereby improving the applicability of the detection mechanism to different detection scenarios and needs.
[0027] Specifically, the mounting assembly 21 includes a support plate 211 and a connecting frame 212. The support plate 211 is located beside the conveyor line 1 and is installed vertically near the bottom of the conveyor line 1, providing a support base for the entire mounting assembly. The connecting frame 212 is perpendicular to the wire conveying direction and is positioned horizontally across the top of the conveyor line 1. One end of the connecting frame 212 is movably connected to the support plate 211, extending from the attached... Figure 1 As can be clearly seen, the two are connected through the cooperation of a slider and a groove, and locked in place by fasteners. This allows the connecting frame 212 to be flexibly adjusted in the vertical direction to meet the needs of different detection height positions. The other end of the connecting frame 212 is connected to the mounting plate 213 for mounting the detection camera 22.
[0028] Furthermore, the detection camera assembly 22 includes a controller 221 and an industrial camera 222. The controller 221 is fixedly mounted on the side of the mounting plate 213 facing the direction of the wire conveying, while the industrial camera 222 is mounted on the front side of the mounting plate 213 via an adjustment bracket and is electrically connected to the controller 221 to ensure that the controller can acquire the image information collected by the industrial camera in real time.
[0029] The adjustment bracket includes two fixed plates 223 symmetrically positioned at both ends of the bottom of the mounting plate 213, and two first adjustment plates 224 movably connected to the two fixed plates 223 respectively. Each fixed plate 223 has a waist-shaped adjustment hole 2231. The two first adjustment plates 224 are rotatably connected to their corresponding fixed plates 223 via a rotating shaft 225, allowing the first adjustment plate to rotate around the shaft at a certain angle. The fixed plates and the first adjustment plates are locked together by fasteners passing through the waist-shaped adjustment holes 2231, ensuring both stability after adjustment and flexibility, allowing the angle of the industrial camera to be adjusted according to actual testing requirements.
[0030] Furthermore, to enable further position adjustment of the industrial camera, the adjustment bracket also includes a second adjustment plate 226, on which the industrial camera 222 is fixed. The two ends of the second adjustment plate 226 correspond to the connection positions of the two first adjustment plates 224, and vertically arranged connection slots 2261 are respectively opened. Fasteners are passed through the connection slots 2261 and locked to the first adjustment plates 224, thereby enabling the second adjustment plate to be adjusted vertically relative to the first adjustment plate, further expanding the adjustment range of the industrial camera's angle and position, and better meeting the diverse needs of wire detection under different complex working conditions.
[0031] See Figure 1 , Figure 4 and Figure 5 At the end of the conveyor line 1, a receiving funnel 3 is provided. The receiving funnel 3 includes a funnel body 31 that is connected to the conveyor line 1, and a receiving pipe 32 located at the bottom of the funnel body 31. The top of the funnel body 31 is provided with an inlet 311 and an arc-shaped guide 312 facing the conveyor belt 12. In actual production, the wire is conveyed rapidly on the conveyor belt. When it is conveyed to the end of the conveyor belt, it falls in a parabolic state due to inertia. The arc-shaped guide 312 ensures that the wire can fall accurately into the funnel body 31.
[0032] A horizontal section 313, integrally connected to the arc-shaped guide section 312, is located on the side opposite to the feed inlet 311. This horizontal section 313 is equipped with a proximity switch 314 (model B4V) for detecting the amount of skein inside the funnel body 31. When the skein buildup in the funnel body 31 reaches the sensing range of the proximity switch 314, the switch is triggered, immediately stopping the skein separation system and ensuring the safety and stability of the entire production process.
[0033] Furthermore, a hopper 33 is provided at the bottom of the funnel body 31, which connects to the receiving pipe 32. The hopper 33 contains a stem collector 331, and the top opening of the stem collector 331 connects to the outlet of the funnel body 31. That is, the receiving pipe 32 is connected to the funnel body 31 through the stem collector 331, so that the stems in the funnel body 31 can be collected uniformly by the tobacco stem conveying pipe connected to the rear end of the receiving pipe 32.
[0034] The stalk collector 331 has a discharge port 3311 on the side facing the receiving pipe 32. The discharge port 3311 is connected to the receiving pipe 32 by a clamp-type quick connector 34. The clamp-type quick connector 34 has the advantages of quick connection, convenient disassembly, and good sealing, which improves the installation and maintenance efficiency of the equipment, while ensuring that the stalks will not leak during the conveying process, thus ensuring the cleanliness of the production environment and the stability of the production process.
[0035] Furthermore, a dust collection chamber 35 is formed between the stem collector 331 and the inner wall of the hopper 33. The hopper 33 has a dust collection pipe interface 333 on its side wall adjacent to the receiving pipe 32, communicating with the dust collection chamber 35. A through hole 334 for the connecting pipe 332 is formed on the side wall of the hopper 33 facing the same direction as the receiving pipe 32. A gap 335 is provided between the through hole 334 and the connecting pipe 332. The dust collection chamber 35 communicates with the receiving pipe 32 through the gap 335. This system collects dust generated during the processing of stems by other mechanisms in the stem separation system and collects it along with the stems, achieving a compact and rational layout.
[0036] In summary, the stem transfer detection device provided by this utility model is set between the secondary air separation process and the tobacco stem conveying pipeline, so that the stem quantity ratio can be detected in real time before entering the receiving funnel. This moves quality control forward to the air separation stage. If abnormal quantity ratio is detected, production parameters can be adjusted in time, improving production controllability and ensuring stable product quality.
