Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco leaf threshing and redrying, and particularly relates to a supporting wheel and a leaf conditioning machine. Background Art

[0002] In the processing of tobacco leaf redrying, the leaf conditioning machine is the main equipment in the threshing and redrying processing line. Its purpose is to increase the moisture content in the tobacco leaves, improve the processability of the tobacco leaves, and make the quality of the tobacco slices more standardized and consistent. Generally, a drum-type hot air leaf conditioning machine is used for threshing and redrying, which includes a feeding chamber, a leaf conditioning drum, a hot air system, a discharging chamber, a frame, a main pipeline system, a pipe cabinet system, a main drive system, a leaf conditioning drum lifting system, etc.

[0003] As Figure 1 and Figure 2 shown, the leaf conditioning drum 11 is inclined with the left end lower and the right end higher. The left rolling ring 12 of the leaf conditioning drum 11 is supported by two supporting wheels 13 arranged on its front and rear sides, and the right rolling ring of the leaf conditioning drum is also supported by two supporting wheels arranged on its front and rear sides. During installation, the supporting wheel is sleeved on the supporting wheel shaft 15, and one end of the supporting wheel shaft is coaxially connected with the output shaft of the motor. During operation, the motor drives the supporting wheel shaft and the supporting wheel 13 to rotate accordingly, and the supporting wheel drives the rolling ring and the leaf conditioning drum to rotate by the friction force between its outer circumferential surface and the rolling ring. During operation, since the leaf conditioning drum is constantly running, the installation position of the supporting wheel will change due to the vibration of the frame 14 of the leaf conditioning machine, and the friction between the supporting wheel and the rolling ring of the leaf conditioning drum will cause wear of the supporting wheel. Therefore, accurately judging whether the contact between the supporting wheel and the rolling ring is uniform and sufficient, that is, judging whether the installation position of the supporting wheel is appropriate and whether the supporting wheel is excessively worn, is very crucial for ensuring the stable operation of the leaf conditioning drum.

[0004] In the prior art, usually, the inspection personnel regularly observe the contact situation between the supporting wheel and the rolling ring to judge whether the contact between the supporting wheel and the rolling ring is uniform and sufficient and the wear situation of the supporting wheel, and then adjust the installation position of the supporting wheel so that the leaf conditioning drum can operate stably. However, relying on manual regular observation, the accuracy of the observation results is greatly related to the work experience of the inspection personnel, lacking a standardized detection method, and it is difficult to ensure the accuracy of the results. Therefore, how to conveniently and intuitively know the wear situation of the supporting wheel and reduce the requirements for the work experience of the inspection personnel has become a technical problem urgently to be solved by those skilled in the art. Summary of the Utility Model

[0025] Now, various exemplary embodiments of the present invention will be described in detail with reference to the attached drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps described in these embodiments do not limit the scope of the present invention.

[0026] The following description of at least one exemplary embodiment is actually merely illustrative and in no way constitutes any limitation to the present invention and its application or use.

[0027] For technologies, methods, and devices known to those of ordinary skill in the relevant field, detailed discussions may not be made, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.

[0028] 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.

[0029] As Figure 3 and Figure 4 shown, the embodiment of the present invention provides a supporting roller. On the right end face 22 of the supporting roller 21, at least two color - different color rings 41 are nested in sequence from outside to inside. The centers of each of the color rings 41 coincide with the center of the shaft hole of the supporting roller 21. The outer diameter of the outermost color ring 41 is equal to the diameter of the supporting roller 21. On the right end face 22 of the supporting roller, a plurality of scale lines 31 extending radially are also provided, and each of the scale lines 31 is evenly distributed in the circumferential direction of the shaft hole.

[0030] For the supporting roller provided by the embodiment of the present invention, at least two color - different color rings 41 are nested in sequence from outside to inside on its right end face 22. A plurality of scale lines 31 extending radially are also provided on this right end face. Each of the scale lines 31 is evenly distributed in the circumferential direction of the shaft hole of the supporting roller. When in use, the inspector only needs to observe which color ring is worn, its degree of wear, and each scale line, and can more conveniently and intuitively know the wear condition of the supporting roller, reducing the requirements for the inspector's work experience.

[0031] In one embodiment, the number of the color rings 41 is three. Preferably, the three color rings are, from outside to inside, a green color ring, a white color ring, and a gray color ring.

[0032] In another embodiment, the number of the color rings 41 is five. Preferably, the five color rings are, from outside to inside, a green color ring, a white color ring, a gray color ring, a yellow color ring, and a red color ring.

[0033] Furthermore, the widths of the respective color rings 41 in the radial direction can be equal. It can be understood that the respective color rings 41 are nested with each other from outside to inside, that is, in two adjacent color rings, the inner diameter of the outer color ring is equal to the outer diameter of the inner color ring, that is, the inner circular line of the outer color ring coincides with the outer circular line of the inner color ring; the supporting wheel 21 is sleeved on the supporting wheel shaft 23 through a shaft hole.

[0034] Specifically, the number of the scale lines 31 is six.

[0035] An embodiment of the present invention further provides a leaf conditioning machine, which includes two supporting wheels for respectively supporting the front and rear sides of the left rolling ring of the leaf conditioning cylinder and two supporting wheels for respectively supporting the front and rear sides of the right rolling ring of the leaf conditioning cylinder, and the four supporting wheels are all the supporting wheels 21 described in any of the above technical solutions.

[0036] It should be noted that when the two supporting wheels located on the front and rear sides of the left rolling ring are in uniform and sufficient contact with the left rolling ring, the wear rates of the two supporting wheels are the same, that is, when the two supporting wheels are in use, they will be worn to the same color ring and the wear amount on the color ring is the same. If the inspectors observe that the wear degrees of the two supporting wheels are different, such as the two supporting wheels are respectively worn to different color rings or although both are worn to the same color ring but the wear amount on the color ring is different, it can be determined that the leaf conditioning cylinder is biased towards the supporting wheel with a larger wear degree, so that the inspectors can adjust the installation position of the supporting wheel 21 based on this, such as making the supporting wheel with a larger wear degree approach the supporting wheel with a smaller wear degree or raising the position of the supporting wheel with a larger wear degree in the vertical direction, so that after adjustment, the two supporting wheels are both in uniform and sufficient contact with the left rolling ring. The observation method of the wear conditions on the two supporting wheels located on the front and rear sides of the left rolling ring is the same as that of the above two supporting wheels, and will not be elaborated here.

[0037] After the supporting wheel is used for a long time or when all the color rings are worn off, the inspectors can conveniently, visually and accurately know the wear conditions of the respective supporting wheels by observing the scale values of the respective scale lines 31 arranged in the radial direction on the right end face of the supporting wheel at the worn positions, which provides a basis for adjusting the installation positions of the respective supporting wheels, and at the same time, it can also be judged whether the supporting wheel is out of round and whether it is still suitable for use in the leaf conditioning machine according to the wear conditions of the supporting wheel.

[0038] Specifically, the left end face of the supporting roller has the same structure as its right end face 22. That is, the above-mentioned various color rings and each graduation line same as those on the right end face can also be provided on the left end face of the supporting roller, so that the use of the supporting roller is more convenient, and the wear condition can be observed from both the left and right directions. At the same time, there is no need to distinguish during installation.

[0039] The supporting roller of the present utility model is provided with a plurality of color rings 41 and a plurality of graduation lines 31, which is convenient for the inspectors to observe the wear condition of each supporting roller in real time and make accurate judgments, so as to facilitate understanding whether the installation positions of the supporting rollers are appropriate for timely adjustment. At the same time, the size and installation method of the supporting roller are the same as those of the original supporting roller on the leaf conditioning machine, without increasing the installation difficulty. By only observing the wear condition of the color rings and the graduation lines, the operation condition and wear degree of the supporting roller can be known, avoiding the situation that the inspectors with insufficient experience cannot detect the minute changes of the supporting roller. Moreover, the present utility model reflects the relatively minute wear condition of the supporting roller through obvious color rings and precise graduation lines, ensuring the reliability and accuracy of the observation results. It can also be used for the detection of the operation condition of other transmission components for friction rotation, observing the wear condition of the transmission component in real time and adjusting the installation position of the transmission component.

[0040] Although some specific embodiments of the present 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 present 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 present utility model. The scope of the present utility model is defined by the appended claims.
