Description

Technical Field

[0001] This application relates to the field of tobacco production technology, and in particular to anti-deviation vehicles and tobacco storage systems. Background Technology

[0002] In tobacco production, tobacco storage cabinets are used to store materials and regulate the entire production line, ensuring that the mixed materials fully absorb the moisture and liquid applied to them in the previous process to meet the requirements of the production line. The material spreading trolley moves back and forth on the guide rails of the storage cabinet, evenly spreading the material from the previous process onto the support belt layer by layer, ensuring uniform distribution of the material within the storage cabinet. This is crucial for subsequent processing and mixing.

[0003] Currently, the trolley system used in the production of expanded tobacco generally suffers from insufficient guiding stability. Traditional trolleys employ a single-sided wheel structure with a rim, relying on the interaction between the wheel rim and the side of the track to limit lateral movement. However, due to the installation span of up to 60 meters, millimeter-level installation errors are unavoidable at the guide rail joints, leading to localized bending or misalignment of the entire track. When the trolley runs on a non-linear track, continuous dry friction occurs between the wheel rim and the track side. This abnormal friction can cause multiple hazards: firstly, it can lead to plastic deformation of the wheel axle system (including the wheel body, axle, and bearings), shortening the service life of critical components; secondly, the instantaneous high temperature generated by friction may ignite the tobacco raw materials, posing a significant safety hazard; furthermore, trolley misalignment can cause uneven distribution of the tobacco, affecting the density of the tobacco layer and the uniformity of temperature and humidity distribution, ultimately reducing the quality grade of the finished tobacco. Utility Model Content

[0004] Therefore, it is necessary to provide a tow deviance prevention system and tobacco storage system to address the problem of poor guiding stability of existing fabric storage cabinets.

[0005] An anti-deviation trolley includes a main body, wheels, and a deviation correction device. The wheels are rotatably connected to the main body, and at least one wheel is provided on each side of the main body. Wheels on the same side of the main body are rotatably connected to the same track. The deviation correction device includes a bracket and a guide wheel rotatably connected to the bracket. The bracket is fixedly connected to the main body to move synchronously with the main body. The axis of the guide wheel and the axis of the wheel are set at an angle. When the wheel is rotatably connected to the track, the guide wheel is rotatably connected to the other end face of the track.

[0006] In one embodiment, the axis of the guide wheel is perpendicular to the axis of the wheel.

[0007] In one embodiment, at least one of the correction devices is provided on each side of the main body, and the correction devices on both sides of the main body are symmetrically arranged.

[0008] In one embodiment, the wheel includes a wheel body and a rim located at one end of the wheel body along its own axial direction, the wheel body being rotatably connected to a track, and the rim protruding from the circumferential surface of the wheel body and located on one side of the track.

[0009] In one embodiment, the guide wheel is located on the side of the wheel body away from the wheel rim.

[0010] In one embodiment, the wheels located on both sides of the body are arranged opposite each other, and the rim of each wheel is located at one end of the wheel body near the other wheel arranged opposite each other.

[0011] In one embodiment, the steering correction device and the wheel are arranged in a one-to-one correspondence.

[0012] In one embodiment, the bracket includes an upper support member and a lower support member spaced apart, and the correction device further includes a support shaft connected to the bracket, with both ends of the support shaft connected to the upper support member and the lower support member respectively, and the guide wheel sleeved on the outer periphery of the support shaft and rotatably connected to the support shaft.

[0013] In one embodiment, the bracket includes a first connecting segment and a second connecting segment connected to each other, the first connecting segment and the second connecting segment being arranged at an angle, and the end of the first connecting segment away from the second connecting segment being fixedly connected to the main body, and the end of the second connecting segment away from the first connecting segment being connected to the guide wheel.

[0014] A tobacco storage system includes a cabinet with an internal storage space, and the top of the cabinet is provided with parallel tracks. It also includes an anti-deviation trolley as described in any of the above embodiments, wherein each of the wheels is selectively and rotatably connected to the tracks, and the guide wheel on the same side as the wheel is rotatably connected to the end face of the track away from the other track.

[0015] The anti-deviation trolley provided in the above solution uses a deviation correction device. The guide wheel and the wheel axis of the deviation correction device are set at an angle and act on different end faces of the track. The forces in different directions restrict each other, thereby preventing the wheel from deviating from the track during rolling. Even if there is local bending or deviation of the overall track, it can be adjusted in time by the deviation correction device, avoiding friction deformation and damage between the wheel and the track caused by deviation. It also avoids the problem of uneven material distribution caused by trolley deviation, thereby improving the service life and production quality stability of the tobacco storage system.

[0027] See Figure 1 , Figure 1 A schematic diagram of a tobacco storage system 10 according to an embodiment of this application is shown. This application provides a tobacco storage system 10 that can be applied in the tobacco production field, but is not intended to limit its application. Figure 1As shown, the tobacco storage system 10 includes a cabinet 200 with an internal storage space, and a parallel track 210 on the top of the cabinet 200. It also includes an anti-deviation trolley 100 as described in any of the following embodiments. The anti-deviation trolley 100 moves along the track 210 to spread the material in the storage space of the cabinet 200.

[0028] like Figure 1 As shown, in one embodiment of this application, an anti-deviation vehicle 100 is also provided. The anti-deviation vehicle 100 includes a main body 110, wheels 120, and a deviation correction device 130. The wheels 120 are rotatably connected to the main body 110, and at least one wheel 120 is provided on each side of the main body 110. The wheels 120 located on the same side of the main body 110 are rotatably connected to the same track 210.

[0029] Combination Figure 2 As shown, Figure 2 A schematic diagram of the correction device 130 in one embodiment of this application is shown. The correction device 130 includes a bracket 131 and a guide wheel 132 rotatably connected to the bracket 131. The bracket 131 is fixedly connected to the main body 110 to move synchronously with the main body 110. The axis of the guide wheel 132 and the axis of the wheel 120 are set at an angle. When the wheel 120 is rolling on the track 210, the guide wheel 132 is rolling on the other end face of the track 210, thereby realizing that the wheel 120 and the guide wheel 132 act on different end faces of the track 210. By utilizing the mutual restriction between the different end faces, the wheel 120 is prevented from deviating during the rolling process.

[0030] like Figure 1 As shown, each wheel 120 is selectively and rotatably connected to the track 210, and the guide wheel 132 on the same side as the wheel 120 is rotatably connected to the end face of the track 210 away from the other track 210, so as to prevent the wheel 120 from deviating towards the inside of the track 210 by the force between the guide wheel 132 and the track 210, thereby achieving the function of preventing the wheel 120 from deviating.

[0031] like Figure 1 As shown, in one embodiment, the axis of the guide wheel 132 is perpendicular to the axis of the wheel 120, but this is not a limitation. In other embodiments, the axis of the guide wheel 132 and the axis of the wheel 120 can also be set according to the included angle between different end faces of the track 210. In this embodiment, the wheel 120 is rolletically connected to the upper end face 211 of the track 210, and the guide wheel 132 is rolletically connected to the side end face 212 of the track 210. The upper end face 211 and the side end face 212 are perpendicular to each other.

[0032] In one embodiment, at least one correction device 130 is provided on each side of the main body 110, and the correction devices 130 on both sides of the main body 110 are symmetrically arranged so that the wheel 120 can be prevented from shifting inward and outward by the correction devices 130 on both sides at the same time, thereby achieving a better correction effect.

[0033] like Figure 1 As shown, in one embodiment, the wheel 120 includes a wheel body 121 and a rim 122 located at one end of the wheel body 121 along its own axial direction. The wheel body 121 is rotatably connected to the track 210. The rim 122 protrudes from the circumferential surface of the wheel body 121 and is located on one side of the track 210. The rim 122 itself has a correction effect. By utilizing the structural constraint of the rim 122 protruding from the circumferential surface of the wheel body 121, the wheel 120 cannot deviate in the opposite direction to the direction with the rim 122.

[0034] like Figure 1 As shown, in one embodiment, the guide wheel 132 is located on the side of the wheel body 121 away from the wheel edge 122. When the wheel 120 is tilted relative to the track 210, the wheel edge 122 will have friction on the inner or outer side of the track 210, while the guide wheel 132 has the force to drive the main body 110 to drive the wheel 120 to deflect in the opposite direction and avoid the wheel edge 122 from rubbing against the track 210, thereby realizing the correction function.

[0035] like Figure 1 As shown, in one embodiment, the wheels 120 located on both sides of the main body 110 are arranged opposite each other, and the rim 122 of each wheel 120 is located at the end of the wheel body 121 close to the opposite wheel 120. That is, when the wheel 120 is tilted relative to the track 210, without the action of the guide wheel 132, the rim 122 will rub against the inner surfaces of the two parallel tracks 210. At this time, the guide wheel 132 acts on the outer surface of the track 210 to prevent the wheel 120 from shifting and causing the rim 122 to rub against the inner surface of the track 210.

[0036] In other embodiments, the rims 122 of the wheels 120 may also be located at the end of the wheel body 121 away from the opposite wheel 120. That is, when the wheel 120 is tilted relative to the track 210, the rims 122 will rub against the opposing inner surfaces of the two parallel tracks 210, and the rims 122 will rub against the opposing outer surfaces of the two parallel tracks 210. At this time, the guide wheel 132 acts on the inner surface of the track 210 to prevent the wheel 120 from shifting and causing the rims 122 to rub against the outer surface of the track 210.

[0037] In one embodiment, the correction device 130 and the wheel 120 are arranged in a one-to-one correspondence to make the correction effect of the correction device 130 more stable.

[0038] like Figure 2 As shown, in one embodiment, the bracket 131 includes an upper support member 1313 and a lower support member 1314 spaced apart. The correction device 130 also includes a support shaft 133 connected to the bracket 131, with both ends of the support shaft 133 connected to the upper support member 1313 and the lower support member 1314 respectively. Figure 3 As shown, the guide wheel 132 is sleeved on the outer periphery of the support shaft 133 and rotatably connected to the support shaft 133. In the axial direction of the support shaft 133, the guide wheel 132 is located between the upper support member 1313 and the lower support member 1314.

[0039] like Figure 2 and Figure 3 As shown, in this embodiment, the correction device 130 further includes fastening bolts 135, which are detachably connected to the support shaft 133. The two ends of the support shaft 133 pass through the upper support member 1313 and the lower support member 1314, respectively, and the two fastening bolts 135 are respectively connected to the two ends of the support shaft 133. One of the fastening bolts 135 is located on the side of the upper support member 1313 away from the lower support member 1314, and the other fastening bolt 135 is located on the side of the lower support member 1314 away from the upper support member 1313, thereby limiting the support shaft 133 in its axial direction.

[0040] like Figure 3 As shown, the correction device 130 also includes a bearing 134, which is located between the guide wheel 132 and the support shaft 133 to achieve a rotatable connection between the two. However, this is not a limitation, and in other embodiments, the guide wheel 132 may also adopt other rotatable connection methods.

[0041] like Figure 2 As shown, in one embodiment, the bracket 131 includes a first connecting segment 1311 and a second connecting segment 1312 connected together. The first connecting segment 1311 and the second connecting segment 1312 are arranged at an angle, and the end of the first connecting segment 1311 away from the second connecting segment 1312 is fixedly connected to the main body 110. The end of the second connecting segment 1312 away from the first connecting segment 1311 is connected to the guide wheel 132, so that the area sandwiched between the first connecting segment 1311 and the second connecting segment 1312 can avoid the wheel 120 and the track 210, thus preventing the bracket 131 from interfering with the normal rolling of the wheel 120. In this embodiment, the first connecting segment 1311 and the second connecting segment 1312 are arranged perpendicularly.

[0042] The anti-deviation trolley 100 provided in the above solution, by setting up a deviation correction device 130, utilizes the guide wheel 132 and the wheel 120 in the deviation correction device 130, whose axes are set at an angle and act on different end faces of the track 210, so that the forces in different directions mutually restrict each other, thereby preventing the wheel 120 from deviating from the track 210 during rolling. Even if the overall track 210 has local bending or deviation, it can be adjusted in time by the deviation correction device 130, avoiding friction deformation and damage between the wheel 120 and the track 210 due to deviation, and also avoiding the problem of uneven material distribution caused by trolley deviation, thereby improving the service life and production quality stability of the tobacco storage system 10.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
