Description

Technical Field

[0001] The utility model relates to the technical field of cigarette preparation, and in particular, to a material classification and recovery device. Background Art

[0002] Fragrance adding machines and feeders are widely used in tobacco processing. They are used to add flavors or sugars to cigarettes during the production of cigarettes and tobacco leaves. During production, flavors or sugars are added to material tanks, collectively referred to as materials. When production is completed, the residual liquid in the material tank needs to be discharged, weighed, and the return accuracy and density calculated.

[0003] Now there are more and more equipment for material push and recovery. For example, Chinese patent utility model patent CN209989343U proposes a material return device for spice production, including a box body without a cover on the top, a pressing mechanism, an extraction mechanism and a material return mechanism. The upper edges of the box body are respectively hinged with cover plates by hinges. The two cover plates are respectively provided with semicircular holes on the edges of one side near the center of the box body. The two semicircular holes form a circular hole. The pressing mechanism is matched in the circular hole. The extraction mechanism is located below the pressing cylinder. The bottom of the box body is provided with a material return mechanism. The lower walls of the box body are respectively provided with through holes. The material return mechanism includes a conveying mechanism. The conveying mechanism is respectively provided with an extraction liquid box and a material receiving box. A water pump is provided on one side of the extraction liquid box. The water pump is respectively connected to the extraction liquid box and the pressing mechanism through a pipeline. Compared with the prior art, the utility model has the advantages of reasonable structure, high working efficiency and convenient material return.

[0004] However, the above-mentioned material return device still has the following disadvantages: it still only makes material return convenient, but when returning the material, the operator is still required to manually weigh the residual liquid in the return tank, calculate the return accuracy, and manually send the remaining material back to the gum material room, where the staff of the gum material room will check the density of the remaining material and compare it. When multiple production lines for adding cigarettes are working at the same time, there are multiple material return operations at all times, which makes the work intensity of returned material recovery calculation very high, greatly wasting manpower and material resources, and the operator is inevitably prone to recovery calculation errors under such high-intensity work, resulting in no guarantee of return accuracy, affecting the next tobacco production process, and no guarantee of stable tobacco production.

[0005] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient material sorting and recycling device. Utility Model Content

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0031] Technologies, methods, and systems known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be considered part of the authorization specification.

[0032] Embodiment 1: Figure 1 The figure is only one of the embodiments of the present invention, a material classification and recovery device, including a material tank 1, an inspection part 2 and a recovery part 3, the inspection part 2 includes a metering tank 21, a weighing device 22 arranged at the bottom of the metering tank 21 and a level gauge 23 arranged at the top of the inner side of the metering tank 21; the material tank 1 is connected with the metering tank 21 through a conveying pipe 11, the recovery part 3 includes a first recovery pipe 31 and a second recovery pipe 32 connected with the metering tank 21, a recovery bucket 33 is arranged at the lower end of the first recovery pipe 31, and a check bucket 34 is arranged at the lower end of the second recovery pipe 32, a first valve 111 is arranged at the conveying pipe 11, a second valve 311 is arranged at the first recovery pipe 31, and a third valve 321 is arranged at the second recovery pipe 32;

[0033] The utility model further comprises a controller, and the weighing device 22, the liquid level meter 23, the first valve 111, the second valve 311 and the third valve 321 are all electrically connected to the controller.

[0034] In the utility model, materials such as flavors, spices or sugars are added to the material tank 1 for direct use in feeding tobacco leaves. After the feeding is completed, the remaining materials in the material tank 1 need to be recovered. At this time, the controller controls the first valve 111 to open, so that the remaining materials in the material tank 1 reach the metering tank 21 through the conveying pipe 11; the inspection unit 2 inspects the return accuracy and return density of the material reaching the metering tank 21 through the weighing device 22 and the liquid level meter 23. If both the return accuracy and the return density are qualified, the controller controls the second valve 311 to open, and the material in the metering tank 21 reaches the recovery barrel 33 through the first recovery pipe 31, and is transported back to the material room for the next use; otherwise, if either the return accuracy and the return density are abnormal, the controller controls the third valve 321 to open, and the material in the metering tank 21 reaches the review barrel 34 through the second recovery pipe 32, and enters the manual review process.

[0035] Among them, the detection method in the metering tank 21 is as follows:

[0036] The weighing device 22 under the metering tank 21 obtains the mass of the metering tank 21 before and after the remaining material reaches the metering tank 21 and sends it to the controller. The controller calculates the mass m2 of the remaining material according to the mass difference before and after the remaining material reaches the metering tank 21. According to the total amount m1 of the material added to the material tank 1 at the beginning of tobacco leaf preparation and the amount of material added m3 used for tobacco leaf preparation, the material return accuracy p=100%*(m1-m3) / m2 can be calculated;

[0037] In addition, the liquid height of the material in the metering tank 21 can be obtained according to the liquid level meter 23, and the material volume V can be calculated according to the model and bottom area of ​​the metering tank 21, and the returned material density q = m2 / V can be calculated.

[0038] If the calculated return material accuracy is within the range of 100%±1%, the return material accuracy is normal. Otherwise, it enters the manual review process and the system alarm prompts that the return material accuracy is abnormal; the calculated liquid material density is compared with the liquid material density of the current production brand in the database. If the comparison error is within 100%±1%, it is normal. Otherwise, it is abnormal and needs to enter the manual review process. The system alarm prompts that the return material liquid density is abnormal.

[0039] Of course, an alarm is provided at the second recovery pipe 32 for reporting abnormalities in the return accuracy and the return liquid density.

[0040] In this way, through the control of the controller, through the coordination of the valves of the conveying pipe, the first recovery pipe and the second recovery pipe, as well as the weighing and liquid measuring at the metering tank, the material return situation can be intelligently detected, the return accuracy and material-liquid density can be automatically calculated and compared, and when abnormal data occurs, manual review can be notified to ensure that the return is reasonable and stable, reduce manpower consumption, and ensure stable tobacco production.

On the basis of the first embodiment, in a material classification and recovery device of the present invention, the liquid level meter 23 is an ultrasonic liquid level meter, which performs non-contact continuous measurement, thereby avoiding material residue, corrosion, pollution, etc. caused by contact type measuring instruments contacting materials, and the continuity of measurement data is better. Moreover, the high-frequency vibration of the ultrasonic wave has a certain surface self-cleaning ability, so that when the liquid in the metering tank 21 is recovered, the liquid on the tank wall can be ultrasonically shaken off to prevent liquid residue, thereby greatly reducing the liquid contamination of the material recovered next time.

[0042] In the utility model, a first scraper 211 and a second scraper 212 are provided in the metering tank 21, and the first scraper 211 is connected to the side wall of the metering tank 21 through a first telescopic rod 213; the second scraper 212 is connected to the side wall of the metering tank 21 away from the first telescopic rod 213 through a second telescopic rod 214; the first scraper 211 and the second scraper 212 are arranged in parallel, and can approach and move away from each other under the extension and retraction of the first telescopic rod 213 and the second telescopic rod 214; the liquid is scraped on the inner wall of the metering tank 21 to further avoid liquid residue.

[0043] It should be noted that when the material in the material tank enters the metering tank 21, the first scraper 211 and the second scraper 212 move away from each other, so that the material enters the space between the first scraper 211 and the second scraper 212, and the liquid level meter 23 is arranged at the upper end between the first scraper 211 and the second scraper 212, and the first recovery pipe 31 and the second recovery pipe 32 are arranged at the lower end between the first scraper 211 and the second scraper 212, so that the material entering the space between the first scraper 211 and the second scraper 212 can be effectively and conveniently ultrasonically measured for the liquid level and ultrasonically cleaned out.

[0044] In addition, the first telescopic rod 213 and the second telescopic rod 214 are both provided with a driving motor, and the motor shaft of the driving motor is provided with an encoder for obtaining the number of rotations of the motor shaft, so as to obtain the positions of the first telescopic rod 213 and the second telescopic rod 214, and also obtain the distance between the first scraper 211 and the second scraper 212. The encoder is electrically connected to the controller, and the volume of the liquid in the metering tank 21 can be known through the distance between the first scraper 211 and the second scraper 212 and the reading of the liquid level meter 23.

[0045] Embodiment three, as Figures 1 to 5 The figure shown is only one embodiment of the present invention. Based on any of the above embodiments, in a material classification and recovery device of the present invention, the height of the material tank 1 is higher than the height of the metering tank 21, and the first recovery pipe 31 and the second recovery pipe 32 are both connected to the bottom surface of the metering tank 21.

[0046] In addition, the conveying pipe 11 includes a first pipe section close to the material tank 1 and a second pipe section close to the metering tank 21. The first valve 111 is arranged on the first pipe section, and the second pipe section is provided with an ultrasonic liquid guide. There are multiple ultrasonic liquid guides to prevent material from remaining in the conveying pipe 11.

[0047] In the present invention, an AGV trolley 35 is provided at the lower side of the recovery barrel 33, and the AGV trolley returns the recovery barrel to the sweetener material warehouse.

[0048] In the present invention, the number of the liquid level meter 23 is at least one, and multiple liquid level meters can avoid measurement errors.

[0049] In the present invention, the number of the material tank 1 and the conveying pipe 11 is at least one, so that the materials in multiple material tanks 1 can be inspected and recovered in sequence.

[0050] Finally, the inner wall of the metering tank 21 is provided with an antistatic coating to effectively avoid static adsorption inside the tank.

[0051] The utility model discloses a material classification and recovery device with a simple structure. Through the cooperation of the valves of the conveying pipe, the first recovery pipe and the second recovery pipe, as well as the weighing and liquid measuring at the metering tank, the material return situation can be intelligently detected, the material return accuracy and the material-liquid density can be automatically calculated and compared, and when the data is abnormal, manual review can be notified to ensure that the material return is reasonable and stable, which reduces manpower consumption and ensures the stability of tobacco leaf production.
