[0031] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0032] like Figures 1 to 3 As shown, this utility model embodiment provides a cigarette end content detection device, including: a housing 1, and a feeding hopper 2, a conveying assembly 3, a screening assembly 4 and a weighing assembly 5 disposed inside the housing 1.
[0033] The side wall of the casing 1 is provided with a feed inlet 11, and the feed hopper 2 is connected to the feed inlet 11.
[0034] The conveying component 3 is located on the feeding side.
[0035] The screening component 4 includes a first screening section 41 and a second screening section 42. The second screening section 42 is located below the first screening section 41. The first screening section 41 includes a tobacco screening plate 411, a tobacco tray 412 and a first tray 413. The tobacco screening plate 411 is above the tobacco tray 412 and the first tray 413. The tobacco tray 412 is located between the tobacco screening plate 411 and the first tray 413. The weighing component 5 is connected to the tobacco tray 412 and the second screening section 42 respectively.
[0036] Specifically, during use, the conveying assembly 3 transports the cigarettes from the feed hopper 2 to the first screening section 41, where the cigarettes are cut into tobacco shreds, filter rods, cigarette paper, and tobacco dust.
[0037] Next, the tobacco, filter rod, cigarette paper, and tobacco dust fall onto the tobacco sieve plate 411. Larger items such as the filter rod and cigarette paper are discharged. When the tobacco sieve plate 411 vibrates, the tobacco, cigarette paper, and tobacco dust separate. The tobacco and tobacco dust fall into the tobacco tray 412. At this time, the tobacco tray 412 is weighed by the weighing component 5 to obtain the first weight, which is the total weight of the tobacco and tobacco dust.
[0038] Next, the tobacco shreds and tobacco dust fall into the second screening section 42. Through the action of the second screening section 42, the tobacco shreds and tobacco dust are separated, and then the weighing component 5 weighs the tobacco shreds to obtain a second weight, which is the weight of the tobacco dust. The tobacco dust content can then be calculated.
[0039] The cigarette dust content is equal to the second weight / the first weight.
[0040] This utility model places the second screening section 42 below the second screening section 42, and places the tobacco screening plate 411 above the tobacco tray 412 and the first tray 413, with the tobacco tray 412 located between the tobacco screening plate 411 and the first tray 413, and the weighing component 5 connected to the tobacco tray 412 and the second screening section 42 respectively. In use, the conveying assembly 3 transports the cigarettes from the feed hopper 2 to the first screening section 41, where the cigarettes are cut into shredded tobacco, filter rods, cigarette paper, and tobacco dust. Then, the shredded tobacco, filter rods, cigarette paper, and tobacco dust fall onto the tobacco shredding plate 411. When the tobacco shredding plate 411 vibrates, the shredded tobacco, cigarette paper, and tobacco dust separate, and the shredded tobacco and tobacco dust fall into the tobacco tray 412. At this time, the weighing assembly 5 weighs the tobacco tray 412. Next, the shredded tobacco and tobacco dust fall into the second screening section 42. Through the action of the second screening section 42, the shredded tobacco and tobacco dust are separated, and the weighing assembly 5 weighs the shredded tobacco. By weighing twice, the weight of the tobacco dust can be obtained. This invention eliminates the need for manual stripping of cigarettes and removal of tobacco, resulting in a high degree of automation. Furthermore, the weight of the shredded tobacco and tobacco dust can be measured simultaneously without changing the tobacco tray 412 during operation, reducing the labor intensity of operators and saving measurement time.
[0041] In one embodiment of the cigarette tip content detection device of this utility model, such as Figure 1 and Figure 2 As shown, the first screening section 41 also includes a connecting shaft 414, which is respectively disposed at both ends of the tobacco screening plate 411, and the two ends of the connecting shaft 414 are respectively connected to the tobacco screening plate 411 and the first tray 413.
