Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

[0035] like Figure 1 and Figure 2 As shown in the embodiment, an electronic belt scale is provided, which can be used on the tobacco processing production line in the cigarette manufacturing process.

[0036] In some embodiments, the electronic belt scale may include a conveying assembly 100, a frame 200, a side rail 300, and a stop 410. The conveying assembly 100 is used to convey materials, which may be tobacco. The frame 200 may be disposed on one side of the conveying assembly 100 and spaced apart from it. This avoids wear and tear on the conveying assembly 100 caused by the frame 200, extending the service life of the conveying assembly 100. In some embodiments, the frame 200 may be spaced apart on the conveying side of the conveying assembly 100, i.e., the side of the conveying assembly 100 used to transport materials. In some embodiments, the frame 200 may be disposed close to one side of the conveying assembly 100 and may be substantially perpendicular to the conveying assembly 100.

[0037] In this embodiment, along the width direction of the conveying assembly 100, one side of the retaining edge 300 can be connected to the side of the frame 200 facing the conveying assembly 100. That is, one side of the retaining edge 300 can be connected to the side of the frame 200 facing the interior of the conveying assembly 100. The other side of the retaining edge 300 can abut against and fit against the surface of the conveying assembly 100 facing the conveying side, and is close to the edge of the conveying assembly 100.

[0038] Therefore, the baffle 300 can prevent the material on the conveying component 100 from entering the gap between the frame 200 and the conveying component 100, thus avoiding material leakage. At the same time, it can also prevent the conveying component 100 from deviating due to dirt accumulation.

[0039] In some embodiments, the stop 410 may be connected to the frame 200. The stop 410 may be located between the stop edge 300 and the conveying assembly 100, and there is a gap between the stop 410 and the conveying assembly 100, thereby preventing the stop 410 from interfering with the operation of the conveying assembly 100.

[0040] Additionally, the stop 410 can be located on the side of the flange 300 that contacts the conveyor assembly 100, facing the frame 200. Thus, the stop 410 prevents the portion of the flange 300 that contacts the conveyor assembly 100 from rolling into the gap between the frame 200 and the conveyor assembly 100, thereby preventing the flange 300 from rolling up. This, in turn, prevents material from entering the gap between the frame 200 and the conveyor assembly 100, avoiding problems such as inaccurate weighing, leaks, and misalignment of the conveyor assembly 100 due to dirt buildup. It also reduces wear on the conveyor assembly 100 and extends its service life.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments, the conveying assembly 100 may include a conveyor belt 110 and a conveyor roller 120. The conveyor belt 110 may be fitted onto the conveyor roller 120, and the conveyor roller 120 may drive the conveyor belt 110 to run. It is understood that the conveyor roller 120 is also connected to a corresponding drive device (not shown) or the like, which can be used to drive the conveyor roller 120 to rotate.

[0042] In some embodiments, the frame 200 may be disposed on the side of the conveyor belt 110 opposite to the conveyor roller 120, and spaced apart from the surface of the conveyor belt 110 opposite to the conveyor roller 120. This avoids friction of the conveyor belt 110 with the frame 200 during operation, reducing wear on the conveyor belt 110.

[0043] In some embodiments, the guard 300 may include an integral connecting portion 310 and a blocking portion 320. The connecting portion 310 may be fixedly connected to the frame 200. The end of the blocking portion 320 away from the connecting portion 310 may be attached to the side of the conveyor belt 110 opposite to the conveyor roller 120, that is, there is no gap between the blocking portion 320 and the conveyor belt 110, which can prevent material from entering the gap between the conveying assembly 100 and the frame 200.

[0044] In some embodiments, the guard edge 300 may be made of a flexible material such as silicone, that is, the guard edge 300 is a flexible guard edge, which may have a certain degree of flexibility, so as to ensure that the blocking part 320 of the guard edge 300 can fit as closely as possible to the conveyor belt 110 and reduce the generation of gaps.

[0045] In some embodiments, the side surface of the blocking portion 320 facing the conveyor belt 110 may also be provided with a wear-resistant layer, which can increase the wear resistance of the blocking edge 300 and extend the service life of the blocking edge 300.

[0046] In some embodiments, the electronic belt scale further includes a pressure plate 500, which can be pressed against the side of the connecting portion 310 away from the frame 200 and is fixedly connected to the frame 200 by means of bolts or snap-fit. Thus, the retaining edge 300 can be kept fixed relative to the frame 200, thereby achieving a fixed connection between the retaining edge 300 and the frame 200.

[0047] In some embodiments, the stop member 410 may be fixedly connected to the frame 200 by means of bonding or other methods. The stop member 410 may extend along the conveying direction of the conveyor belt 110, and the extension length of the stop member 410 may be approximately equal to the conveying length of the conveyor belt 110. In the embodiments, the stop member 410 may be disposed between the blocking part 320 and the conveyor belt 110, and may be disposed at intervals from the conveyor belt 110.

[0048] In other embodiments, the stop member 410 may also be connected to the side of the blocking part 320 facing the conveyor belt 110 by means of bonding or the like, and is located at the end of the blocking part 320 near the connecting part 310.

[0049] In some embodiments, the distance between the stop 410 and the conveyor belt 110 is set to 2 mm.

[0050] In some embodiments, the stop 410 may be an airbag. One end of the stop 410 may be connected to an air source 440, which can be used to supply gas to the stop 410. During operation, the stop 410 can be inflated by the air source 440.

[0051] In other embodiments, the stop 410 may also be a structure such as a stop bar.

[0052] like Figure 2 and Figure 3 As shown, in some embodiments, a control valve assembly 420 is also provided on the pipeline connecting the gas source 440 and the stop member 410, which can be used to control the on / off connection between the gas source 440 and the stop member 410. In some embodiments, the control valve assembly 420 may include a shut-off valve 421 and a solenoid valve 422 arranged in sequence.

[0053] In some embodiments, a pressure sensor 430 is also provided between the air source 440 and the stop member 410, which can be used to detect the pressure in the stop member 410.

[0054] In addition, the electronic belt scale also includes a control module (not shown in the figure), which can be electrically connected to other electrical components in the electronic belt scale. Thus, the control module can uniformly control the operation of each electrical component in the electronic belt scale.

[0055] In summary, the electronic belt scale provided in this application can prevent the blocking portion 320 of the side guard 300 from being drawn into the gap between the frame 200 and the conveying assembly 100 through the stop member 410. This ensures a good fit between the blocking portion 320 and the conveyor belt 110, preventing material from entering the gap between the frame 200 and the conveying assembly 100 through the gap between the side guard 300 and the conveyor belt 110. This avoids problems such as inaccurate weighing, leakage, and misalignment of the conveying assembly 100 due to dirt accumulation, and also reduces wear on the conveying assembly 100, extending its service life.
