Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf loosening and rewetting, in particular to a device for detecting the loosening and rewetting effect of tobacco slices. Background Art

[0002] Tobacco leaf loosening and rewetting is an important link in the processing of tobacco slices. Its main purpose is to increase the temperature of tobacco leaves, increase the moisture content of tobacco leaves, improve the toughness and anti-breakability of tobacco leaves; in this process, after the tobacco leaves are processed, their physical and chemical properties are improved to facilitate subsequent processing and cigarette production. The quality control key points of the loosening and rewetting process include avoiding excessive rewetting of tobacco leaves, because this will cause the tobacco leaves to absorb too much moisture, which will affect their quality and appearance; in addition, whether the quality of the tobacco leaves after loosening and rewetting meets the requirements, such as the moisture content, is also an important aspect of quality control; for example, "Cigarette Process Specification", "Tobacco Slice Inspector" and other books write that the purpose of loosening and rewetting is to increase the moisture content and temperature of tobacco slices, improve the processability of tobacco slices, make the cut tobacco slices loose, and improve the sensory quality of tobacco slices; the moisture content, temperature, and loosening rate of tobacco slices after loosening and rewetting should all meet the production index requirements.

[0003] The loosening and rewetting equipment is generally a drum type. It utilizes the air in the circulating hot air chamber rewetting machine to be in a high-temperature condition, and steam and water mist are sprayed onto the tobacco slices tumbling in the cylinder to achieve the purpose of leaf moistening, loosening and rewetting. The tobacco slices are sent to the feeding screen by the feeding vibrating trough and then enter the rotating drum. Under the action of the rake nails arranged in a spiral pattern and gravity, they tumble forward along the inclined drum. Steam and water nozzles are arranged at both the feeding port and the discharging port of the drum. Under the action of steam and water mist, the temperature of the leaves increases and the moisture content increases.

[0004] The indexes of the loosening and rewetting effect mainly include the loosening rate, the discharging temperature, the outlet moisture content, the hot air temperature, the outlet moisture standard deviation, etc. The loosening rate is an important index to measure the loosening and rewetting effect. The ideal loosening rate should be greater than 90%; at present, to evaluate the loosening effect of tobacco slices, it mainly relies on manually selecting agglomerated tobacco leaves and then weighing to calculate the loosening rate. It is necessary to manually pick up the tobacco leaves at the discharging port of the loosening and rewetting equipment, and then spread out the discharging tobacco slices for selection. However, during the testing process, a large amount of tobacco leaves are usually produced at the loosening and rewetting equipment port. The manual spreading and selection processes often lag behind the discharging, resulting in the accumulation of discharging tobacco leaves, which not only affects the normal production order, but also takes a long time and leads to low production efficiency. Content of the Utility Model

[0005] The object of the present utility model is to provide a device for detecting the loosening and tempering effect of tobacco slices, aiming at the problem in the prior art that tobacco leaves need to be manually taken out from the discharge port of the loosening and tempering equipment, and then the discharged tobacco slices are spread out for selection. Usually, a large amount of tobacco leaves are produced at the discharge port of the loosening and tempering equipment, and the manual spreading and selection processes often lag behind the discharge, resulting in the accumulation of discharged tobacco leaves and affecting the normal production order.

[0006] The solution of the present utility model is a device for detecting the loosening and tempering effect of tobacco slices, comprising: a rotary sampling plate, a scraper, and a conveyor belt;

[0007] The rotary sampling plate is fixed to the outside of the discharge hood through a vertical rotating shaft and can horizontally rotate from between the discharge hood and the discharge vibrating trough to the conveyor belt under the drive of a rotary reduction motor, so as to obtain the detected material after loosening and tempering from below the discharge hood;

[0008] The scraper is fixed above the conveyor belt and is located within the rotation circle of the rotary sampling plate; the height of the scraper is adjacent to and higher than that of the rotary sampling plate, so as to scrape the material to be detected on the rotary sampling plate onto the conveyor belt;

[0009] The tail end of the conveyor belt is connected to the discharge vibrating trough.

[0010] The detection device for the effect of tobacco leaf loosening and tempering according to the present utility model is provided with a rotating sampling plate under the discharge hood of the loosening and tempering machine. During the process that the loosening and tempering machine completes the loosening and tempering of a batch of tobacco leaves and discharges them to the discharge vibrating chute, the rotating sampling plate can be driven by a rotating reduction motor to rotate between the discharge hood and the discharge vibrating chute, so as to obtain the detected material after loosening and tempering according to the set frequency or time. When sampling is not required, it can not rotate between the discharge hood and the discharge vibrating chute. On the one hand, it does not affect the large amount of discharged material under the discharge hood to the discharge vibrating chute, so that the sampling of the detected material does not affect the transportation of most non-detected materials to the next process, thus avoiding the obstruction of normal material transportation caused by manual spreading sampling. Then, by setting a conveyor belt, a scraper and the position of the scraper, when the rotating sampling plate filled with the material sample rotates horizontally above the conveyor belt, the stationary scraper moves in the opposite direction relative to the rotating sampling plate, scraping the material on the rotating sampling plate onto the conveyor belt, and then the conveyor belt is used for manual detection or a detection machine is set in the transportation section of the conveyor belt for detection, so that it is not necessary to manually spread out the material for detection. By connecting the tail end of the conveyor belt to the discharge vibrating chute, the tobacco leaves after detection can be returned to the normal conveying channel for the next process. Therefore, through sampling and detection, the material is returned from the discharge vibrating chute after sampling and detection, conforming to the material transportation, preventing material accumulation and blockage, and avoiding the problems of tobacco leaf accumulation or detection lag, thus not affecting the normal order of production. The present utility model can not only improve the efficiency of sampling and detection, but also drive the rotating sampling plate to sample by a rotating reduction motor, enabling sampling at regular times and frequencies, avoiding missing or under-selecting of caked tobacco leaves, and improving the accuracy of evaluating the loosening rate of tobacco leaves.

[0011] Preferably, for the detection device for the effect of tobacco leaf loosening and tempering according to the present utility model, the conveying speed of the conveyor belt is matched with the rotating speed of the rotating sampling plate.

[0012] As a preferred solution of the present utility model, by controlling the rotating speed of the driving motor of the conveyor belt and the rotating speed of the rotating reduction motor, the conveying speed of the conveyor belt can be matched with the rotating speed of the rotating sampling plate, so that within the time when the rotating sampling plate obtains the detected material and scrapes it onto the conveyor belt, the conveyor belt can move the detected material scraped onto the conveyor belt last time away from under the rotating sampling plate, thereby reducing the overlap of the detected material, improving the recognition degree of the detected material, being beneficial to more clearly and accurately showing the caked tobacco leaves of the detected material in the subsequent process, and further avoiding the situation that the caked tobacco leaves are not recognized, so as to further improve the accuracy of tobacco leaf loosening evaluation.

[0013] Preferably, the apparatus for detecting the loosening and tempering effect of tobacco slices according to the present utility model further includes a detection and analysis system and a machine vision detector disposed above the conveyor belt. The machine vision detector is configured to capture an image of the detection material on the conveyor belt, and the machine vision detector is electrically connected to the detection and analysis system. The detection and analysis system is configured to analyze the loosening and tempering effect of the detection material.

[0014] As a preferred embodiment of the present utility model, by providing a machine vision detector above the conveyor belt, the sampled detection material is transported through the machine vision detector from the conveyor belt, and an image of the detection material can be obtained. Then, the image is transmitted to the detection and analysis system through data transmission. The detection and analysis system automatically analyzes the state of the tobacco slices after loosening and tempering of the detection material, and combines the conditions and indicators of loosening and tempering. Thus, it is possible to analyze and evaluate the loosening and tempering effect of the batch of materials to be loosened and tempered. Capturing the material during the transportation of the detection material does not affect the transportation of the material, enabling the detection analysis and normal material transportation to proceed simultaneously, further improving the detection efficiency and normal production efficiency. Moreover, by obtaining the result through automatic and rapid analysis, the preset and adjustment of loosening and tempering can be carried out quickly, further improving the quality of loosening and tempering.

The second conveying section, the third conveying section, and the fourth conveying section are horizontal conveyors. The conveying direction of the third conveying section turns 180° from the second conveying section to the third conveying section. The tail of the fourth conveying section is connected to the discharge vibrating trough and has the same conveying direction as the discharge vibrating trough.

[0016] As a preferred embodiment of the present utility model, by setting the conveyor belt into four sections and through the inclined conveying effect of the first conveying section, tobacco flakes of different weights can have different frictional forces due to their own gravity, so that the detected materials are continuously spread out on the first conveying section, replacing manual spreading, and improving the efficiency of conveying and selecting caked tobacco leaves. And through the setting of the second conveying section and the third conveying section, the conveying direction can be turned by 180° from the first conveying section, and the detection is completed on the fourth conveying section. Then, the materials are conveyed in the same direction as the discharge vibrating trough through the fourth conveying section, and the detected materials can be returned to the discharge vibrating trough. Without affecting the next process of the detected materials, the processes of loose moisture regain discharge, obtaining detected materials, detecting samples, and returning the detected materials to the discharge vibrating trough are in an orderly manner and run synchronously, further improving the efficiency of the device for detecting the loose moisture regain effect.

[0017] Preferably, for the device for detecting the loose moisture regain effect of tobacco flakes of the present utility model, the machine vision detector is arranged above the fourth conveying section.

[0018] As a preferred embodiment of the present utility model, by arranging the machine vision detector above the fourth conveying section, on the one hand, the machine vision detector can synchronously return the detected materials to the discharge vibrating trough and synchronously obtain the caked tobacco leaf images of the materials automatically when the materials are transported from the discharge vibrating trough to the next process, enabling the tobacco leaf caking detection and the tobacco flake conveying process to be carried out synchronously. Compared with the long time-consuming of manual detection, the efficiency of tobacco leaf loose detection is further improved.

[0019] Preferably, for the device for detecting the loose moisture regain effect of tobacco flakes of the present utility model, the third conveying section is a semi-circular arc conveying section.

On the other hand, the detected materials can be conveyed to the fourth conveying section more smoothly in the semi-circular arc conveying section, further reducing the failure rate of tobacco leaf conveying or avoiding blockage, and further improving the conveying efficiency and detection efficiency.

[0021] Preferably, for the device for detecting the loose moisture regain effect of tobacco flakes of the present utility model, the machine vision detector is fixed above the conveyor belt through a gantry; the width of the gantry matches the width of the conveyor belt; the machine vision detector is fixed in the middle of the gantry.

[0022] As a preferred embodiment of the present utility model, the machine vision detector is fixed by a gantry, which can avoid obstructing the transportation of the detected material. The machine vision detector is fixed in the middle of the gantry to maintain the shooting field of view of the machine vision detector, improve the integrity of the lumped tobacco flakes obtained by the machine vision detector, and further improve the accuracy of the evaluation of the tobacco leaf loosening rate.

[0023] Preferably, for the tobacco flake loosening and tempering effect detection device of the present utility model, the rotary sampling plate is in the shape of a fan-shaped disc; one side of the center of the rotary sampling plate is connected to the rotary reduction motor.

[0024] As a preferred embodiment of the present utility model, by setting the rotary sampling plate as a fan-shaped disc, the smooth rotation of the rotary sampling plate can be maintained. One side of the center of the rotary sampling plate is connected to the rotary reduction motor and serves as the gravity support for carrying the detected material, minimizing the influence of the weight of the detected material on the rotation of the detected material with the rotary sampling plate, further maintaining the rate consistency of the rotation of the rotary sampling plate, and reducing the failure rate of the rotation of the rotary sampling plate.

[0025] Preferably, for the tobacco flake loosening and tempering effect detection device of the present utility model, the scraper is fixed to the side plate of the conveyor belt through a right-angle arm beam and a sliding member; the scraper is horizontally fixed to the upper end of the right-angle arm beam, and the lower end of the right-angle arm beam is slidably connected to the sliding member along the tangent direction of the rotation circle of the rotary sampling plate, and the sliding member is fixed to the side plate.

[0026] As a preferred embodiment of the present utility model, the scraper is fixed to the side plate of the conveyor through a right-angle arm beam and a sliding member. The right-angle arm beam has a stable supporting performance. Moreover, since the scraper is horizontally fixed, the reverse force of the detected material on the rotary sampling plate acting on the scraper is horizontal, and the supporting direction of the right-angle arm beam is vertical, avoiding the influence of the right-angle arm beam on the rotation of the rotary sampling plate and making the device operate more smoothly; on the other hand, by setting the sliding member, the lower end of the right-angle arm beam can be slidably connected to the sliding member along the tangent direction of the rotation of the rotary sampling plate.

After adjusting the position, it is fixed again. According to the actual frequency of the material at the position of the rotary sampling plate, it is temporary to ensure that the material in the rotary sampling tray is completely scraped off, further improving the applicability of the device.

[0029] Preferably, in the tobacco sheet loosening and rewetting effect detection device of the present utility model, a cross baffle and side baffles are provided at one end of the conveyor belt adjacent to the rotary sampling plate; the side baffles include two fixed on both sides of the conveyor belt, and the two side baffles are respectively fixedly connected to both sides of the cross baffle.

[0031] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are:

[0032] (1) It can drive the rotary sampling plate to rotate between the discharge hood and the discharge vibrating trough through the rotary reduction motor, and then can obtain the detected material after loosening and rewetting according to the set frequency or time. When sampling is not required, it can not rotate between the discharge hood and the discharge vibrating trough. On the one hand, it does not affect the discharge of a large amount of material below the discharge hood to the discharge vibrating trough, so that the sampling of the detected material does not affect the transportation of most non-detected materials to the next process, thus avoiding the obstruction of normal material transportation caused by manual spreading sampling; through the conveyor belt for manual detection or setting a detection machine in the transportation section of the conveyor belt for detection, and by connecting the tail end of the conveyor belt to the discharge vibrating trough, the detected tobacco sheets can also be returned to the normal transportation channel for the next process, conforming to the material transportation, preventing material accumulation and blocking, and avoiding problems such as tobacco leaf accumulation or detection lag, so as not to affect the normal order of production and improving the production efficiency.
