Description
Technical Field
[0001] This utility model belongs to the field of tobacco processing and production technology, and specifically relates to an online measuring device for the amount of cigarette recycle in a cigarette machine. Background Technology
[0002] The tobacco recycling device in a cigarette rolling machine mainly consists of a main recycling conveyor belt, a secondary recycling conveyor belt, and a tobacco dropping trough. The main recycling conveyor belt runs from front to back, transporting tobacco from the secondary recycling conveyor belt and the tobacco trimmed by the leveling disc to the rear tobacco dropping trough. Afterward, the tobacco enters the recycling storage area and is re-entered into the tobacco suction and forming system for use by the cigarette rolling machine. The weight of this portion of tobacco is the recycling amount. Because the recycled tobacco is subjected to the shearing force of the leveling disc, it can cause breakage and reduce the tobacco's structure. When the recycling amount is too large, it can easily lead to problems such as loose ends, weight, large fluctuations in draw resistance and hardness, and poor consistency in filling density, affecting the quality of the cigarettes. Therefore, accurately weighing the recycling amount, studying the relationship between the recycling amount and rolling quality, and controlling the recycling amount within an appropriate range are of great significance for improving the rolling quality of cigarette rolling machines and enhancing brand appeal.
[0003] The current industry method for measuring recycled tobacco is as follows: during equipment operation, the VE rear door is opened, and tobacco shreds collected from the 1-minute dropping trough are weighed. However, due to the up-and-down vibration of the dropping trough during equipment operation and the small receiving area, some material falls from the side of the trough, making it impossible to collect all the tobacco shreds per unit time. This results in low accuracy of the measurement results, and the operation of the mechanical equipment poses a significant threat to the safety of the experimental personnel. How to safely and accurately weigh the recycled tobacco is a challenge facing the industry.
[0004] Therefore, there is an urgent need for an online measurement device for the amount of recycled yarn that can accurately, in real time and safely weigh the recycled yarn. Utility Model Content
[0005] The purpose of this invention is to provide an online measurement device for the amount of tobacco scrap in a cigarette machine, thereby overcoming the technical problems of existing methods for measuring tobacco scrap in cigarette machines. These methods suffer from low accuracy due to the up-and-down vibration of the tobacco scrap trough, a small receiving area, and the inability to completely collect tobacco scrap per unit time. Furthermore, the operation of the mechanical equipment poses a significant safety threat to the experimental personnel. The specific technical solution is as follows:

[0030] Example
[0031] like Figure 1 and Figure 2 As shown, this utility model embodiment provides an online measurement device for the amount of tobacco shreds in a cigarette machine, used for online measurement of the amount of tobacco shreds. It includes a main tobacco shred conveying mechanism 1, a secondary tobacco shred conveying mechanism 2 located upstream of the main tobacco shred conveying mechanism 1, and a tobacco drop trough 3 located downstream of the main conveying mechanism. The main tobacco shred conveying mechanism 1 receives tobacco shreds conveyed by the secondary tobacco shred conveying mechanism 2, the tobacco drop trough 3 receives tobacco shreds delivered by the main tobacco shred conveying mechanism 1, and the secondary tobacco shred conveying mechanism 2 receives tobacco shreds falling from the suction umbrella and those split and shaved by the leveling device. The secondary tobacco shred conveying mechanism 2 is higher than the main tobacco shred conveying mechanism 1, and the main tobacco shred conveying mechanism 1 is higher than the tobacco drop trough 3.
[0032] In some preferred embodiments, the wire dropping trough 3 is inclined, with the feed end of the wire dropping trough 3 being higher than its discharge end, and the inclination angle of the wire dropping trough 3 being 10° to 15°.
[0033] Preferably, the auxiliary return yarn conveying mechanism 2, located upstream of the main return yarn conveying mechanism 1, has its discharge end connected to the feed end of the main return yarn conveying mechanism 1; the yarn dropping trough 3, located downstream of the main return yarn conveying mechanism 1, has its discharge end connected to the main return yarn conveying mechanism 1.
[0034] Specifically, the secondary return wire conveying mechanism 2 is a belt conveyor. Belt conveyors are existing technology and can be purchased on the market, so they will not be described in detail here.
[0035] Preferably, the main return yarn conveying mechanism 1 includes a conveying section, a protective section, and a weighing section, wherein the protective section and the weighing section are mounted on the conveying section.
[0036] In some preferred embodiments, the conveying unit includes a mounting bracket, a drive roller 105, a driven roller 106, a conveyor belt 101, and a drive motor 104. Notably, the drive motor 104 is a geared motor, which is mounted on the mounting bracket. The output end of the drive motor 104 is connected to the drive roller 105. The drive roller 105 and the driven roller 106 are rotatably mounted on the mounting bracket and located at opposite ends of the mounting bracket. The conveyor belt 101 is sleeved on the drive roller 105 and the driven roller 106. Driven by the drive motor 104, the conveyor belt 101 rotates, thereby realizing the conveying of tobacco shreds.
[0037] In some preferred embodiments, the weighing unit includes a plurality of weighing rollers 107, a plurality of pressure sensors 108, and a control module. The weighing rollers 107 are mounted on the mounting bracket and located between the drive roller 105 and the driven roller 106. The pressure sensors 108 are mounted on the weighing rollers 107, and the sensing surface of the pressure sensors 108 abuts against the conveyor belt 101. The pressure sensors 108 are used to monitor the changes in the weight of the tobacco on the conveyor belt 101 in real time. The control module is mounted on the mounting bracket and is electrically connected to the pressure sensors 108 and the drive motor 104. The control module receives the signals fed back by the pressure sensors 108 and controls the drive motor 104.
[0038] It is worth mentioning that the number of weighing rollers 107 and pressure sensors 108 is the same, and the pressure sensors 108 are used in conjunction with the weighing rollers 107. The number of weighing rollers 107 is not less than three.
[0039] Preferably, in order to prevent tobacco from falling off both sides of the conveyor belt 101 during the conveying process, a protective part is provided on the mounting bracket. The protective part includes a protective baffle 102 and a cover plate 103. The protective baffle 102 is installed on opposite sides of the mounting bracket to separate the two sides of the conveyor belt 101. The cover plate 103 is installed on the protective baffle 102. The cover plate 103 further prevents tobacco from falling off the conveying mechanism during the conveying process.
[0040] In some preferred embodiments, the control module includes a controller 109 and a display screen; the display screen, the drive motor 104, and the pressure sensor 108 are all electrically connected to the controller 109.
[0041] The controller 109 is used to control the drive motor 104 to rotate so as to drive the drive roller 105 to rotate, thereby causing the conveyor belt 101 to carry the tobacco shreds downstream. It is also used to receive the weight information of the tobacco shreds collected by the pressure sensor 108 and display the weight information of the tobacco shreds to the staff in real time through the display.
[0042] In use, the value collected by the pressure sensor 108 when the conveyor belt 101 is empty is taken as the first weight parameter. When the tobacco falls onto the conveyor belt 101, the value collected by the pressure sensor 108 increases and is recorded as the second weight parameter. The difference between the second weight parameter and the first weight parameter is taken as the weight of the tobacco, so as to achieve accurate, real-time and safe measurement of the weight of the tobacco.
[0043] In summary, the online measurement device for the amount of tobacco scrap in a cigarette machine provided by this utility model collects the weight changes of the conveyor belt in real time by setting up a conveyor mechanism with a weighing function, thereby obtaining the real-time weight of the tobacco scraps on the conveyor belt. This solves the technical problems of existing cigarette machine tobacco scrap measurement methods, which suffer from low accuracy due to the up-and-down vibration of the dropping groove and the small material receiving area, which causes some material to fall from the side of the groove, making it impossible to completely collect the tobacco scraps per unit time. Furthermore, the operation of the mechanical equipment poses a significant threat to the safety of the experimental personnel.
