Description

Technical Field

[0001] This application relates to the field of cigarette production technology, and in particular to a check mechanism, a cleaning device, and cigarette production equipment. Background Technology

[0002] In tobacco production, tobacco leaves and shredded tobacco need to be conveyed into the conveyor belt. To ensure even distribution, the conveyor belt moves in both directions. However, tobacco leaves and shredded tobacco easily remain on the belt, requiring brushes to simultaneously rotate and clean them. One end of the brush roller has an adjusting nut, which is prone to loosening due to the reaction force when the roller reverses direction. The threads gradually loosen with the vibration of the movement. Over long-term operation, the adjusting nut repeatedly experiences tightening and loosening, increasing the risk of thread wear. Furthermore, the continuous accumulation of loosening can easily cause the brush roller to become unstable, leading to it detaching from the end bushing. Utility Model Content

[0003] Therefore, it is necessary to provide a check mechanism, a cleaning device, and cigarette production equipment to address the problem that adjusting nuts are easily loosened by reaction forces.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] In a first aspect, embodiments of this application provide a check mechanism, including:

[0006] Adjust the bearing housing;

[0007] The roller body has one end rotatably engaged with the adjusting bearing seat via a bearing.

[0008] A bushing is fitted onto the end of the roller body that connects to the adjusting bearing seat, and rotates with the adjusting bearing seat.

[0009] An adjusting nut is threaded onto the side of the adjusting bearing housing opposite to the roller body and abuts against the bushing.

[0010] The check valve includes a fixed end and a limiting end. The fixed end is fixedly connected to the adjusting bearing seat, and the limiting end is connected to the adjusting nut.

[0011] In one embodiment of the first aspect, the fixed end is arranged parallel to a first direction, and the limiting end is arranged parallel to a second direction, wherein the first direction is parallel to the central axis of the roller body, and the second direction is perpendicular to the central axis of the roller body.

[0012] In one embodiment of the first aspect, the fixed end is provided with a through hole, and one end of the adjusting bearing seat is provided with a mounting hole;

[0013] The anti-return mechanism also includes a through-hole and a locking element. The through-hole passes through the through hole and the mounting hole in sequence and is then connected to the locking element.

[0014] In one embodiment of the first aspect, a groove is provided on one side of the adjusting nut, and the limiting end is engaged in the groove.

[0015] In one embodiment of the first aspect, the two ends of the roller body are square structures.

[0016] In one embodiment of the first aspect, the check mechanism further includes a drive bearing housing, and the end of the roller body away from the adjustment bearing housing is rotatably connected to the drive bearing housing.

[0017] In one embodiment of the first aspect, the anti-return mechanism further includes a drive wheel, the end of the roller body away from the adjusting bearing housing being fixedly connected to the drive wheel after passing through the drive bearing housing.

[0018] Secondly, embodiments of this application also provide a cleaning device, including the check mechanism described in any of the above embodiments.

[0019] In one embodiment of the second aspect, the cleaning device further includes a plurality of brushes, each brush being circumferentially distributed around the outside of the roller along the central axis of the roller, and the brushes being arranged parallel to the central axis of the roller.

[0020] Thirdly, embodiments of this application also provide a cigarette production equipment, including the check mechanism or check mechanism described in any of the above embodiments.

[0021] Compared to related technologies, the advantages of this application are as follows: This application provides a check valve mechanism, a cleaning device, and cigarette production equipment.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] See Figure 1As shown, an embodiment of this application provides a check mechanism 100, which includes an adjusting bearing seat 110, a roller body 120, a bushing, an adjusting nut 130, and a check element 140.

[0040] Specifically, the adjusting bearing housing 110 is fixed to the side bracket of the belt by bolts and has holes for the roller body 120 to pass through. One end of the roller body 120 is rotatably engaged with the adjusting bearing housing 110 via a bearing, so that it can rotate relative to the adjusting bearing housing 110 under the action of external force. It can be understood that a bearing is installed inside the adjusting bearing housing 110, and one end of the roller body 120 passes through the bearing, so that it is rotatably engaged with the adjusting bearing housing 110 via the bearing, thereby reducing the rotational wear of the adjusting bearing housing 110.

[0041] The bushing is fitted onto the end of the roller body 120 that connects to the adjusting bearing seat 110, and passes through the bearing after being installed on the roller body 120, so as to rotate with the adjusting bearing seat 110, thereby enabling the bushing to rotate with the roller body 120 relative to the adjusting bearing seat 110, reducing the rotational wear of the roller body 120.

[0042] The adjusting nut 130 is threaded onto the side of the adjusting bearing housing 110 opposite to the roller body 120, and the insertion length of the adjusting nut 130 is controlled by the thread depth. After the adjusting nut 130 is tightened against the bushing, the tightness of the adjusting bushing on the roller body 120 is adjusted by further tightening it to adjust the rotation speed of the roller body 120.

[0043] Understandably, since the adjusting nut 130 is pressed against the bushing, when the roller body 120 rotates in the opposite direction to the adjusting nut 130, the adjusting nut 130 is prone to loosening. During long-term operation, this will cause the adjusting nut 130 and the adjusting bearing seat 110 to loosen, and in severe cases, the roller body 120 may fall off the bushing.

[0044] The two ends of the check valve 140 are connected to the adjusting bearing housing 110 and the adjusting nut 130, respectively, so that the adjusting nut 130 can remain relatively fixed relative to the adjusting bearing housing 110. Even when the roller body 120 reverses, the adjusting nut 130 remains fixed to the adjusting bearing housing 110 under the restriction of the check valve 140 and will not rotate with the roller body 120, thus preventing the adjusting nut 130 from loosening and improving the installation stability of the roller body 120.

[0045] Continue reading Figure 2 As shown, for example, the check valve 140 includes a fixed end 141 and a limiting end 142. The fixed end 141 and the limiting end 142 are located on different planes to form an L-shaped installation structure, so as to keep the adjusting nut 130 and the adjusting bearing seat 110 relatively fixed in different planes.

[0046] Furthermore, the fixed end 141 is arranged parallel to the first direction y, and the limiting end 142 is arranged parallel to the second direction x. The first direction y is parallel to the central axis of the roller body 120, and the second direction x is perpendicular to the central axis of the roller body 120. The check valve 140 can be a welded metal workpiece to ensure its working strength. One side of the fixed end 141 is perpendicularly connected to one side of the limiting end 142 to facilitate the connection of the adjusting nut 130 and the adjusting bearing seat 110. The overall space occupied is small, reducing interference of the device during industrial operation.

[0047] Continue reading Figure 3 and Figure 4 As shown, in some embodiments, the fixed end 141 has a through hole 143, and one end of the adjusting bearing seat 110 has a mounting hole 112. The check mechanism 100 also includes a through insert 150 and a locking member. The through insert 150 passes through the through hole 143 and the mounting hole 112 in sequence and is then connected to the locking member.

[0048] Specifically, the through-plug 150 and locking element enable a detachable connection between the fixed end 141 and the adjusting bearing housing 110, facilitating the removal and replacement of the check valve 140. Additionally, the other end of the adjusting bearing housing 110 has symmetrically provided mounting holes 112, which are used to fix the housing to the supports on both sides of the belt, ensuring stable installation. The check valve 140 is installed in one mounting hole 112 via the through-plug 150. While installing the check valve 140, the through-plug 150 also secures the adjusting bearing housing 110 to the support, eliminating the need for additional holes and reducing process steps.

[0049] For example, the insert 150 can be a bolt, pin, or other workpiece, and the locking part can be a nut, snap ring, or other similar component. No specific limitation is required here; the appropriate selection can be made based on the working conditions.

[0050] Furthermore, the adjusting bearing housing 110 has a threaded hole 111 so that the adjusting nut 130 locks into the threaded hole 111.

[0051] Continue reading Figure 5 As shown, in some embodiments, a groove 131 is provided on one side of the adjusting nut 130, and the limiting end 142 is engaged in the groove 131.

[0052] Specifically, the limiting end 142 is a flat plate with one side of it locked in the groove 131 of the adjusting nut 130. When the adjusting nut 130 has a tendency to rotate, the side wall of the groove 131 is pressed against by the limiting end 142. The limiting end 142 is fixed on the adjusting bearing seat 110, and the adjusting nut 130 cannot rotate with the roller body 120.

[0053] Continue reading Figure 6As shown, in some embodiments, the two ends of the roller body 120 are square structures. Specifically, since the ends of the roller body 120 are square, the bushing is correspondingly square so that the bushing can rotate with the roller body 120, avoiding the situation where the roller body 120 rotates freely relative to the bushing due to excessive tightness when a circular bushing is used.

[0054] In some embodiments, the check mechanism 100 further includes a drive bearing housing, and one end of the roller body 120 away from the adjusting bearing housing 110 is rotatably connected to the drive bearing housing.

[0055] Specifically, the two ends of the roller body 120 are connected to the adjusting bearing seat 110 and the drive bearing seat respectively to support the two ends of the roller body 120 and maintain the stability of the roller body 120 installation.

[0056] In some embodiments, the check mechanism 100 further includes a drive wheel, with one end of the roller body 120 away from the adjusting bearing seat 110 fixedly connected to the drive wheel after passing through the drive bearing seat.

[0057] Specifically, the transmission wheel can be connected to an external drive mechanism to rotate under the control of the drive mechanism, thereby driving the roller 120 to rotate and achieve the corresponding operation requirements.

[0058] Understandably, the drive mechanism can be a motor, and the transmission wheel can be a pulley, sprocket, or other structure, which is connected to the motor via a transmission belt or chain.

[0059] Embodiments of this application also provide a cleaning device, including the check mechanism 100 in any of the above embodiments.

[0060] This embodiment has the check mechanism 100 of any of the above embodiments, and therefore has all the beneficial effects of the check mechanism 100 of any of the above embodiments, which will not be described in detail here.

[0061] It should be noted that the anti-return mechanism 100 in this embodiment is not limited to its application in cleaning devices. It can also be applied to structures such as conveyor rollers and pressing rollers to achieve different operational capabilities. For ease of understanding, in this embodiment, the anti-return mechanism 100 is applied to the roller brush of a cigarette production equipment to clean tobacco leaves or shredded tobacco on the belt.

[0062] In some embodiments, the cleaning device further includes a plurality of brushes 200, each brush 200 being circumferentially distributed around the outer side of the roller 120 along the central axis of the roller 120, and the brushes 200 being arranged parallel to the central axis of the roller 120. Thus, during the rotation of the roller 120, the roller 120 drives the brushes 200 to rotate, thereby removing tobacco leaves or tobacco shreds from the belt.

[0063] Embodiments of this application also provide a cigarette production apparatus, including the check mechanism 100 or cleaning device in any of the above embodiments.

[0064] This embodiment has the check mechanism 100 or cleaning device of any of the above embodiments, and therefore has all the beneficial effects of the check mechanism 100 or cleaning device of any of the above embodiments, which will not be described in detail here.

[0065] 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.

[0066] 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.
