[0028] On the one hand, if Figure 1-6 As shown, an embodiment of the present invention provides a moisture meter moving device for a tobacco sheet redrying machine, wherein the moisture meter moving device (10) comprises:

[0029] Power member (100);

[0030] A first connecting member (200) and a load-bearing assembly (300), wherein one end of the first connecting member (200) is connected to the power member (100), the first connecting member (200) is used to pass through the top wall (40) of the tobacco sheet redrying machine, and the other end of the first connecting member (200) is connected to the load-bearing assembly (300), and the load-bearing assembly (300) is used to connect to the moisture meter (20);

[0031] The power member (100) is used to drive the first connecting member (200) to move, so as to drive the moisture meter to move and detect the moisture content of the material through the load-bearing component (300), and at least part of the weight of the moisture meter is applied to the load-bearing component (300).

[0032] The tobacco slice re-drying machine includes a housing, and a drying area, a cooling area, and a rehumidification area located inside the housing. The tobacco slices are used as materials and are transported by a belt or a mesh belt in the tobacco slice re-drying machine. The tobacco slices are laid on the belt or the mesh belt, and are driven by the belt or the mesh belt to pass through the drying area, the cooling area, and the rehumidification area in sequence. In the following embodiments, the direction in which the belt or mesh belt drives the tobacco slices to move is referred to as the forward direction, and the direction perpendicular to the forward direction is referred to as the width direction. The width direction of the belt or mesh belt is usually wider, such as 2 to 3 meters, and the tobacco slices are usually laid to the edge in the width direction of the belt or mesh belt.

[0033] The power part (100) can be of various types or structures, and is intended to provide power to drive the moisture meter (20) to move in the width direction. This will be described below in conjunction with more specific embodiments. The power part (100) is located as a whole outside the casing of the tobacco sheet redrying machine, that is, it is isolated from the high temperature and dust environment inside the casing, to avoid the accumulation of debris on the power part (100) causing poor movement, or the detector and other components on the power part (100) being affected by high temperature, resulting in inaccurate detection results, and the power part (100) is exposed outside the casing, which is convenient for disassembly and observation.

[0034] The first connecting member (200) serves as a bridge connecting the power member (100) outside the box and the load-bearing component (300) inside the box, and plays a transmission role. The first connecting member (200) can be a variety of structures, such as a columnar structure. The following is a further detailed description in conjunction with the structure of a tobacco sheet re-drying machine. The tobacco sheet re-drying machine includes a box including a top wall (40) and a frame (30), and the top wall (40) is mounted on the top of the frame (30). The top wall (40) can be a horizontally arranged plate-like structure. A second clearance opening (41) is provided on the top wall (40), and the second clearance opening (41) is a long strip opening that passes through the upper and lower sides of the top wall (40) and extends in the forward direction. The first connecting member (200) passes through the second clearance opening (41), and can be separated from the edge of the second clearance opening (41) by a certain gap.

It can also play the role of stabilizing the movement of the moisture meter (200), and avoiding the problem that the moisture meter (200) is unstable due to the power member (100) and the moisture meter (200) being far apart across the top wall (40).

[0036] During the production process, the present application can drive the moisture meter (200) to move in the width direction to detect the moisture at different positions in the width direction of the tobacco sheet, and control the air volume at different positions in the drying area according to the moisture at different positions in the width direction, such as controlling the air volume of the left and right circulating air, thereby achieving a uniform degree of dryness of the tobacco sheet in the width direction.

[0037] A moisture meter moving device and a tobacco sheet redrying machine proposed in the embodiment of the present invention mainly drive the moisture meter to move through a power part, realize automatic movement to detect the moisture of multiple points of materials, make sampling more comprehensive, and make the detection result more valuable. In the prior art, the moisture meter in the sampling room of the tobacco sheet redrying machine is mostly installed at a fixed position below the top plate, which can only detect the moisture of the material at a fixed position, and cannot realize the full detection of the moisture of the material paving width. Compared with the prior art, in the present application document, the mobile sampling of the moisture meter is realized by driving the power part, and then the sampling of multiple positions of the material on the same conveying progress is realized, the sampling range is increased, and the sampling reference value is greater. The power part is outside the box of the tobacco sheet redrying machine, which avoids the influence of the high temperature and dust environment in the box on the power part, and is easy to install, repair, disassemble, etc. At the same time, the weight of the moisture meter is borne on the load-bearing component, and no vertical force is generated on the power part, thereby avoiding the wear caused by the long-term operation of the power part, and avoiding the increase in energy consumption caused by the heavy load during operation. The overall structure of the device is simple, easy to maintain, and can realize the long-term and effective operation of the device.

Specifically, the load-bearing platform (310) extends in the width direction, and the two ends of the load-bearing platform (310) are respectively fixed on the frame (30) to ensure that the load-bearing platform (310) is stable and not easy to shake. The sliding member (320) can be a plate-like structure, or other structures that can cooperate with the load-bearing platform (310). The load-bearing platform (310) is used to support the sliding member (320) from the bottom of at least part of the structure of the sliding member (320), and then play the role of supporting the weight of the moisture meter (20) by the load-bearing platform (310).

[0049] The first clearance opening (311) is a long strip-shaped opening extending in the width direction. The sliding member (320) is a plate-shaped structure approximately in a square shape and is located above the load-bearing platform (310). The second connecting member (330) may be a rod-shaped structure, passing through the first clearance opening (311) of the load-bearing platform (310), and may be spaced apart from the edge of the first clearance opening (311) by a gap. The sliding member (320) and the first connecting member (200) and the second connecting member (330) may be integrally formed, or may be welded.

[0050] In one embodiment, the load-bearing assembly (300) further includes a plurality of sliding wheels (340), wherein the sliding wheels (340) are disposed on the sliding member (320), and the sliding member (320) is rollingly connected to the load-bearing platform (310) via the sliding wheels (340).
