Description

Technical Field

[0001] This utility model relates to the field of tobacco detection technology, specifically to an automatic cigarette filter rod weight detection device with continuous automatic sampling. Background Technology

[0002] In modern cigarette rolling production, each rolling machine is equipped with a balance testing platform for batch weighing and testing. However, due to the wide range of accuracy requirements in the production stage, the weighing accuracy is not high.

[0003] The general working process is as follows: inspectors manually take samples and measure the total weight of a group of cigarettes, usually 30 cigarettes, on a balance, and calculate the average value. This manual sampling method is usually used as a temporary auxiliary means for operators to adjust the equipment. There is no data recording or unified data judgment and use standard, so it cannot be used for sharing and statistical analysis.

[0004] In the sampling or quality inspection process, the weight of cigarettes can be tested using a comprehensive testing bench, which is usually quite accurate. However, the testing efficiency of the comprehensive testing bench is no more than 5 cigarettes per minute, which is relatively low.

[0005] With the development of the industry, the demand for "lights-out factories" has emerged, emphasizing that the production process also needs to have relatively high detection accuracy and ensure detection efficiency. The purpose is to obtain data from the production process to provide data support for building an intelligent control system.

[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic cigarette filter rod weight detection device with continuous automatic sampling and high detection efficiency.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic cigarette filter rod weight detection device with continuous automatic sampling, including a base, a balance, a balance cantilever, a cigarette tray, a tray lifting mechanism, a scraper mechanism, a cigarette conveyor belt, and a cigarette lifting mechanism.

[0009] The balance is mounted on a base, the balance arm hangs over one side of the balance, and the end of the balance arm forms a support opening;

[0010] The upper arm of the cigarette tray slides vertically with the tray opening. The diameter of the upper arm of the cigarette tray is larger than the diameter of the tray opening, so that the cigarette tray can transfer gravity to the balance through the balance arm by the cooperation between the upper arm and the tray opening.

[0011] The pallet lifting mechanism lifts or moves the cigarette pallet up or down by lifting, and the cigarette pallet is located above the cigarette conveyor belt and is suspended in the air.

[0012] The cigarette lifting mechanism is installed in the cigarette conveyor belt. The cigarette lifting mechanism is used to partially arch up some of the cigarettes in the cigarette conveyor belt so that the height of the cigarettes exceeds the height of the cigarette tray, so that the cigarettes can enter the cigarette tray.

[0013] The scraper mechanism moves horizontally above the cigarette tray and is used to scrape off excess cigarettes from the cigarette tray.

[0014] Based on the above, the support opening includes a horizontal step disposed at the bottom end of the balance arm and a through hole disposed on the horizontal step.

[0015] Based on the above, the bottom tray of the cigarette tray is a V-shaped groove tray, and the top of the upper arm of the cigarette tray is provided with a blocking block with a diameter larger than the perforation. The main body of the upper arm slides in conjunction with the perforation.

[0016] Based on the above, a vertical elongated hole is provided in the middle of the upper arm, and the pallet lifting mechanism includes a drive end and a horizontal plate. The drive end drives the horizontal plate to rise and fall, and the far end of the horizontal plate is inserted into the vertical elongated hole. The height of the horizontal plate is less than the height of the vertical elongated hole.

[0017] Based on the above, the drive end of the scraper mechanism is mounted on the base, the bottom end of the scraper end of the scraper mechanism is aligned with the bottom end and top end of the cigarette tray, and the horizontal movement range of the scraper mechanism covers the width of the cigarette tray.

[0018] Based on the above, the cigarette lifting mechanism includes a triangular stretching belt and a stretching belt drive roller. The bottom edge of the triangular stretching belt is close to and parallel to the surface of the cigarette conveyor belt. The stretching belt drive roller is the apex drive roller of the triangular stretching belt. The stretching belt drive roller can move up and down. When the stretching belt drive roller moves to the highest point, the height of the cigarette in the arched conveyor belt exceeds the height of the cigarette tray.

[0019] Based on the above, the triangular tension band is an elastic band with tensile capacity.

[0020] Based on the above, the scraper end of the scraper mechanism is an L-shaped plate.

[0021] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:

Detailed Implementation

[0028] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0029] like Figures 1-4 As shown, an automatic cigarette filter weight detection device with continuous automatic sampling includes a base 1, a balance 2, a balance cantilever 3, a cigarette tray 4, a tray lifting mechanism 5, a scraper mechanism 6, a cigarette conveyor belt 7, and a cigarette lifting mechanism 8.

[0030] The balance 2 is mounted on the base 1, and the balance arm 3 hangs over one side of the balance. The end of the balance arm 3 forms a support opening 31. In this embodiment, the support opening includes a horizontal step at the bottom of the balance arm 3 and a through hole on the horizontal step.

[0031] The upper arm 41 of the cigarette tray 4 is vertically slidably engaged with the tray opening, and the bottom tray 42 of the cigarette tray 4 is a V-shaped groove tray. Specifically, the top of the upper arm 41 of the cigarette tray 4 is provided with a blocking block 43 with a diameter larger than the perforation, and the main body of the upper arm 41 is slidably engaged with the perforation; so that the cigarette tray 42, through the engagement of the upper arm 41 and the tray opening, transfers gravity to the balance 2 through the balance arm 3.

[0032] In other words, when the cigarette tray 4 does not require external force, all of its weight can be transferred to the balance 2 through the upper arm 41 and the balance cantilever 3, thus making the cigarette tray 4 a weighing platform of the balance 2, and thus the weight of the cigarettes can be accurately measured.

[0033] The V-shaped groove tray should not be too deep, and should be a shallow groove structure. It typically holds 3-5 cigarettes at a time. The purpose is that as the cigarettes flow, new cigarettes can push away old ones, thus achieving cigarette replacement.

[0034] The pallet lifting mechanism 5 lifts or lowers the cigarette tray 4 by lifting, and the cigarette tray 4 is located above the cigarette conveyor belt 7 and is suspended in the air. Specifically, the upper arm 41 is provided with a vertical elongated hole 44 in the middle. The pallet lifting mechanism 5 includes a drive end and a horizontal plate 51. The drive end drives the horizontal plate 51 to rise and fall. The far end of the horizontal plate 51 is inserted into the vertical elongated hole 44. The height of the horizontal plate 51 is less than the height of the vertical elongated hole 44.

[0035] Specifically, when the tray lifting mechanism 5 moves down and the horizontal plate 51 is pressed down to the lower boundary of the vertical elongated hole 44, it can effectively lock the cigarette tray 4 and prevent the cigarette tray 4 from shaking. It mainly works during the process of putting in cigarettes to prevent cigarettes from being unable to enter the cigarette tray 4.

[0036] The cigarette lifting mechanism 8 is disposed in the cigarette conveyor belt 7. The cigarette lifting mechanism 8 is used to partially arch up some cigarettes in the cigarette conveyor belt 7, so that the height of the cigarettes exceeds the height of the cigarette tray 4, so that the cigarettes can enter the cigarette tray 4. Specifically, in this embodiment, the cigarette lifting mechanism 8 includes a triangular stretching belt 81 and a stretching belt drive roller 82. The triangular stretching belt is an elastic belt with tensile capacity and can be stretched and deformed. The bottom edge of the triangular stretching belt 81 is close to and parallel to the surface of the cigarette conveyor belt 7. The stretching belt drive roller 82 is the apex corner drive roller of the triangular stretching belt 81. The stretching belt drive roller 82 can move up and down. When the stretching belt drive roller 82 moves to the highest point, the height of the cigarettes arched in the cigarette conveyor belt exceeds the height of the cigarette tray.

[0037] The scraper mechanism 6 moves horizontally above the cigarette tray 4 to scrape off excess cigarettes from the cigarette tray 4. Specifically, in this embodiment, the drive end of the scraper mechanism 6 is mounted on the base, and the bottom end of the scraper end of the scraper mechanism 6 is aligned with the bottom end and top end of the cigarette tray. The horizontal movement range of the scraper mechanism covers the width of the cigarette tray. The scraper end of the scraper mechanism is an L-shaped plate. Through the horizontal sweeping action, cigarettes higher than the cigarette tray are swept off and returned to the cigarette conveyor belt. The purpose is to quantify the number of cigarettes in the cigarette tray 4.

[0038] Working principle explanation:

[0039] The cigarette conveyor belt 7 is a traditional cigarette conveyor belt, characterized by having side guards on both sides, with cigarettes stacked in multiple layers and flowing horizontally along the cigarette conveyor belt 7.

[0040] When the operation begins, the cigarette tray 4 is located slightly above the top of the stacked cigarette stream, and the cigarette tray 4 serves as the weighing platform for the balance 2.

[0041] When weighing is required, first control the pallet lifting mechanism 5 to descend, press down the upper arm 41 of the cigarette tray 4, so that the cigarette tray 4 is stable as a whole.

[0042] Then, the stretching belt drive roller 82 in the cigarette lifting mechanism 8 is moved upward, so that the apex of the triangular stretching belt is moved upward, so as to form an arched fluid peak in the cigarette stream, the height of which exceeds the height of the cigarette tray 4.

[0043] The cigarette tray 4 and the cigarette lifting mechanism 8 are positioned close to each other in the horizontal direction so that the fluid peak formed is located near the upstream of the cigarette tray 4, and some cigarettes enter the cigarette tray 4 with the height bulge and the horizontal thrust of the cigarette conveyor belt 7.

[0044] The cigarette tray 4 is designed as a V-shaped groove structure tray with fixed structural dimensions, so it can store a fixed number of cigarettes. To ensure that the number of cigarettes stored is determined, a leveling step is performed.

[0045] The drive scraper mechanism 6 works, and the scraper mechanism 6 horizontally sweeps across the upper surface of the cigarette tray 4 to scrape off the excess cigarettes stacked on it, thus fixing the number of cigarettes in the cigarette tray 4.

[0046] Finally, the pallet lifting mechanism 5 is moved upward to release the cigarette tray 4, so that the cigarette tray 4 is no longer subject to external force, restoring the weighing platform function of the balance. The balance reading is then read to obtain the total weight of the cigarettes. Based on the quantity, the weight of each cigarette is calculated and the data is entered into the database for later use. Then, the cigarettes are put back in their original positions.

[0047] During the next weighing, when the cigarette tray 4 picks up a new cigarette, the original cigarettes are pushed away horizontally by the flow of cigarettes, leaving the newly loaded cigarettes. The newly loaded cigarettes are then weighed to obtain the weight of the new cigarettes.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
