Description
Technical Field
[0001] The utility model belongs to the technical field of tobacco leaf threshing and redrying, and specifically designs an adjusting device for the supporting wheels of a leaf conditioning cylinder. Background Art
[0002] The drum-type hot air leaf conditioner is located in the pre-treatment section of tobacco leaf threshing and redrying, and is one of the main equipment on the threshing and redrying line. During the process of processing materials, tobacco leaves are sent to the inlet of the drum-type hot air leaf conditioner by a vibrating conveyor and enter the interior of the leaf conditioning cylinder of the drum-type hot air leaf conditioner from the feed hopper. Since the leaf conditioning cylinder rotates continuously and the included angle with the horizontal plane is 3° to 5°, the tobacco leaves entering the leaf conditioning cylinder continuously fall from the feed end. This movement makes the tobacco leaves loose mechanically to a certain extent and move along the axial direction of the leaf conditioning cylinder towards the discharge end until they are discharged.
[0003] As Figure 1 shown, the left rolling ring 12 of the leaf conditioning cylinder 11 is supported by two supporting wheels 13 arranged on its front and rear sides. The right rolling ring of the leaf conditioning cylinder is also supported by two supporting wheels arranged on its front and rear sides. During installation, the supporting wheels are sleeved on the supporting wheel shafts, and one end of the supporting wheel shaft is coaxially connected to the output shaft of the motor. During operation, the motor drives the supporting wheel shaft and the supporting wheels 13 to rotate accordingly. The supporting wheels drive the rolling ring and the leaf conditioning cylinder to rotate by the friction force between their outer circumferential surfaces and the rolling ring. Since the leaf conditioning cylinder is inclined with the left end lower and the right end higher and forms an included angle of 3° to 5° with the horizontal plane, after the leaf conditioning cylinder rotates for a long time, it is easy to slide down and move upwards, resulting in unstable operation. Although there are stop wheels on the leaf conditioner to block the left and right rolling rings, the stop wheels should not be in contact with the left and right rolling rings for a long time to block and generate a large blocking force, so as to avoid damage to the left and right rolling rings and the inability of the leaf conditioning cylinder to rotate.
[0004] Therefore, in the prior art, generally, the installation positions of the above four supporting wheels are adjusted to change the attitude of the leaf conditioning cylinder, thereby changing the rolling condition of the leaf conditioning cylinder, achieving the purpose of eliminating the movement of the leaf conditioning cylinder and making the leaf conditioning cylinder operate stably. However, during the adjustment, the adjustment amount of the installation position of the supporting wheels is determined by making marks or observing traces. Due to too many marks or blurred marks and unclear traces, it is very easy to not be able to conveniently and intuitively see the adjustment amount, and thus the adjustment amount cannot be well controlled, resulting in a time-consuming and laborious adjustment process and low adjustment efficiency. Therefore, how to design an adjusting device for the supporting wheels of a leaf conditioning cylinder to effectively improve the adjustment efficiency has become a technical problem that needs to be urgently solved by those skilled in the art.

[0030] Known technologies, methods and devices for those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods and devices should be regarded as part of the specification.
[0031] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.
[0032] As Figures 2 to 4As shown in the figure, an adjustment device for a leaf conditioning cylinder supporting wheel according to an embodiment of the present utility model includes two adjustment assemblies 51, and the two adjustment assemblies 51 are respectively arranged at the left and right ends of a supporting wheel shaft 31. The adjustment assembly includes a bearing seat 52, a wedge block 53, a first fixing plate 562, a second fixing plate 572, a horizontal scale 55, and a vertical scale 54. The bearing seat 52 is rotatably connected to the supporting wheel shaft 31, and the wedge block 53 is arranged between the bearing seat and the frame 41 of the leaf conditioner; a first waist-shaped hole for the threaded section of a connecting bolt 521 to pass through is arranged on the bearing seat, the first waist-shaped hole extends in the front-rear direction, a second waist-shaped hole opposite to the first waist-shaped hole is arranged on the wedge block, and a threaded hole opposite to the second waist-shaped hole is arranged on the frame; the first fixing plate 562 is arranged on the frame and in front of the wedge block, a first threaded hole for cooperating with the threaded section of a first adjusting bolt 56 is arranged on the first fixing plate, two first locking nuts 561 are arranged on the threaded section of the first adjusting bolt, and the two first locking nuts are respectively located on both sides of the first fixing plate. The rear end of the first adjusting bolt is rotatably connected to the front end of the wedge block; the second fixing plate 572 is arranged at the front end of the inclined top surface 531 of the wedge block, a second threaded hole for cooperating with the threaded section of a second adjusting bolt 57 is arranged on the second fixing plate, two second locking nuts 571 are arranged on the threaded section of the second adjusting bolt, and the two second locking nuts are respectively located on both sides of the second fixing plate. The rear end of the second adjusting bolt is rotatably connected to the front end of the bearing seat; the horizontal scale is horizontally arranged on the side surface of the frame and directly below the wedge block. A third waist-shaped hole 541 for the threaded section of a mounting screw 542 to pass through is arranged on the vertical scale 54, and a third threaded hole opposite to the third waist-shaped hole is arranged on the bearing seat; the vertical scale extends in a direction perpendicular to the inclined top surface of the wedge block, the third waist-shaped hole is in the same extending direction as the vertical scale, and the lower end of the vertical scale 54 is in contact with the upper end of the horizontal scale 55.
[0033] The adjusting device for the supporting wheel of the leaf moistening cylinder provided by the embodiment of the present utility model, when it is necessary to adjust the installation position of the supporting wheel, first loosen the connecting bolt and move the two first locking nuts away from each other, and then rotate the first adjusting bolt to make the first adjusting bolt 56 move back and forth in the first threaded hole, which can drive the wedge block 53 and the bearing seat to move back and forth accordingly, so as to realize the adjustment of the position of the supporting wheel in the front-back direction. After the adjustment is completed, move the two first locking nuts 561 close to each other until both of them are tightly pressed against the first fixing plate. During the above adjustment process, the connecting bolt slides in the first waist-shaped hole and the second waist-shaped hole, and the lower end of the vertical scale slides back and forth on the upper end of the horizontal scale. By observing the scale indicated by the lower end of the vertical scale on the horizontal scale, it is possible to conveniently and intuitively see the adjustment amount of the supporting wheel in the front-back direction, which is convenient for accurately controlling the adjustment amount, so that the adjustment process is time-saving and labor-saving, and effectively improves the adjustment efficiency; moreover, move the two second locking nuts away from each other, rotate the second adjusting bolt 57 to make the second adjusting bolt move back and forth in the second threaded hole, and drive the bearing seat to move on the inclined top surface of the wedge block, then it is possible to realize the simultaneous adjustment of the position of the supporting wheel in the front-back direction and the vertical direction. After the adjustment is completed, move the two second locking nuts 571 close to each other until both of the second locking nuts are tightly pressed against the second fixing plate, and tighten the connecting bolt to lock both the bearing seat and the wedge block on the frame. During the above adjustment process, the lower end of the vertical scale slides back and forth on the upper end of the horizontal scale. By observing the scale indicated by the lower end of the vertical scale on the horizontal scale, it is possible to conveniently and intuitively see the adjustment amount of the supporting wheel in the front-back direction. At the same time, relying on the self-gravity of the vertical scale, the mounting screw slides up and down in the third waist-shaped hole. By observing the scale indicated by the inclined top surface on the vertical scale, it is possible to conveniently and intuitively know the adjustment amount of the supporting wheel 21 in the vertical direction, that is, the height direction, so as to be able to conveniently and accurately control the adjustment amount of the supporting wheel in the front-back direction and the vertical direction, and further make the adjustment process of the supporting wheel time-saving and labor-saving, and effectively improve the adjustment efficiency.
[0034] Further, the number of the third kidney-shaped holes 541 is two, and the two third kidney-shaped holes are distributed vertically along the extension direction of the vertical scale 54; the number of the third threaded holes is two, and the two third threaded holes correspond to the two third kidney-shaped holes one by one. With this solution, by using two mounting screws to cooperate with the two third kidney-shaped holes one by one, it is possible to better guide and limit the up and down movement of the vertical scale in the direction perpendicular to the inclined top surface, effectively avoiding the vertical scale from rotating around the mounting screws. It can be understood that the wedge block is a trapezoidal block with a lower front and a higher rear; the screw head of the mounting screw 542 does not press the vertical scale, but only limits the vertical scale to prevent it from coming out. The horizontal scale is used to support the vertical scale. Therefore, when the bearing seat moves forward and upward along the inclined top surface of the wedge block, the lower end of the vertical scale always contacts the horizontal scale under its own gravity. The vertical scale only moves forward with the bearing seat and does not move upward with it. At this time, the mounting screw moves with the bearing seat and slides upward in the third kidney-shaped hole. When the bearing seat moves backward and downward along the inclined top surface, the mounting screw slides downward in the third kidney-shaped hole, and the lower end of the vertical scale always contacts the horizontal scale. At this time, the vertical scale only moves backward with the bearing seat and does not move downward with it; when the vertical scale moves back and forth along the inclined top surface of the wedge block with the bearing seat, the inclined top surface will indicate different scales on the vertical scale.
[0035] Specifically, the lower end of the vertical scale 54 is a triangular structure, so that the scale indicated by the tip of the triangular structure on the horizontal scale can more intuitively obtain the adjustment amount in the front and rear directions. Preferably, the triangular structure is a right-angled triangular structure as shown in Figure 4 Figure, and its hypotenuse is close to the upper end of the horizontal scale. It can be understood that scales are provided on the vertical scale and the horizontal scale in their respective extension directions. The zero scale line of the horizontal scale can be located at the middle position thereof, and the zero scale line of the vertical scale is located at the lower end of the vertical scale; the second adjusting bolt is perpendicular to the front end of the bearing seat.
[0036] Further, the number of the first kidney-shaped holes is two, and the two first kidney-shaped holes are oppositely arranged on the front and rear sides of the bearing seat 52; the number of the second kidney-shaped holes is two, and the two second kidney-shaped holes correspond to the two first kidney-shaped holes one by one; the number of the threaded holes is two, and the two threaded holes correspond to the two second kidney-shaped holes one by one. With this solution, by passing two connecting bolts 521 through the first kidney-shaped holes and the second kidney-shaped holes respectively and then cooperating with the threaded holes and then tightening them, the bearing seat 52 and the wedge block 53 can be more firmly locked on the frame 41.
[0037] In specific use, it is possible to select whether to use the first adjustment bolt 56 or the second adjustment bolt 57 for adjustment according to the actual adjustment requirements. Of course, the first adjustment bolt and the second adjustment bolt can also be used in combination for adjustment. If only the position of the bearing block and the supporting roller in the vertical direction, i.e., the height direction, needs to be adjusted, the second adjustment bolt can be rotated first to make the adjustment amount of the bearing block in the vertical direction meet the requirements, and then the first adjustment bolt can be rotated to place the bearing block at its original position in the front-back direction before adjustment. For example, before adjusting the height, the bearing block is at the position where the vertical scale indicates the zero scale line of the horizontal scale. After adjustment, the bearing block can be reset to the above position by rotating the first adjustment bolt.
[0038] It can be understood that by simultaneously adjusting the two adjustment components 51 provided at the left and right ends of the same supporting roller shaft 31, the positions of the supporting roller 21 mounted on the supporting roller shaft in the front-back direction and the vertical direction can be adjusted. The four supporting rollers used to support the left and right rolling rings of the leaf conditioning cylinder respectively all use this adjustment device. After the leaf conditioning cylinder moves up or down, the attitude of the leaf conditioning cylinder can be adjusted conveniently and quickly, enabling the leaf conditioning cylinder to resume stable operation as soon as possible and improving production efficiency.
[0039] Preferably, a shaft hole 522 is provided on the bearing block 52, a first bearing is provided in the shaft hole, and the supporting roller shaft is arranged in the inner ring of the first bearing, thus conveniently realizing the rotational connection between the bearing block 52 and the supporting roller shaft 31 by using the bearing. It can be understood that the outer ring of the first bearing is in interference fit with the shaft hole, and the inner ring of the first bearing is in interference fit with the supporting roller shaft. When the supporting roller shaft rotates, the inner ring rotates in the outer ring. The bearing is a commonly used component in the prior art and will not be elaborated here.
[0040] Specifically, a blind hole opposite to the first threaded hole is provided at the front end of the wedge block 53, a second bearing is provided in the blind hole, and the rear end of the first adjustment bolt 56, i.e., the end away from its bolt head, is arranged in the inner ring of the second bearing, thus conveniently realizing the rotational connection between the first adjustment bolt and the wedge block 53 by using the second bearing. Similarly, the second adjustment bolt 57 and the front end of the bearing block can also be rotationally connected in this way.
[0041] The utility model can visually and conveniently adjust the position of the support wheels of the leaf conditioning cylinder, without the need to mark on the frame and observe the fuzzy movement traces. By directly reading the values on the two scales, the adjustment amount can be known. At the same time, when the leaf conditioning cylinder is in an ideal operating state, the values corresponding to the two scales of the adjustment devices of all support wheels can be recorded, enabling the staff to better understand the position states of the support wheels at this time. In subsequent maintenance, problems can be handled more quickly and simply according to the above-recorded values, improving the maintenance efficiency. Moreover, the adjustment device realizes the quantification of the adjustment amount, which has guiding significance and popularization value in daily standardized operations. And, the adjustment device can be used on other equipment whose running state of the cylinder needs to be adjusted.
[0042] Although some specific embodiments of the utility model have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the utility model. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the utility model. The scope of the utility model is defined by the appended claims.
