[0002] In the cigarette production process, conveyor lines are often used to transport and transfer items. Generally, a power head is set up to provide conveying power to the conveyor line. The power head includes a drive source and a drive shaft. The drive source provides rotational power to the drive shaft, and the drive shaft then transmits the rotational power to the conveyor line.

[0003] After prolonged use, the drive shaft will experience metal fatigue and become prone to deformation. This will change the stress applied to the drive shaft by the drive source, which will further exacerbate the deformation of the drive shaft and eventually lead to its breakage, affecting production progress. Summary of the Invention

[0004] The purpose of this invention is to overcome the problem of drive shafts being prone to deformation and breakage by providing a power head stabilization structure. This stabilization structure can reduce the stress borne by the drive shaft in the power head during operation, thereby alleviating the situation of drive shaft deformation and breakage.

[0005] To achieve the above objectives, this utility model provides a power head stabilization structure for stabilizing the drive source and drive shaft in a power head. The power head stabilization structure includes:

[0006] A frame for rotatably connecting the drive shaft in a first direction;

[0013] This utility model also provides a cigarette conveying line, including a conveying device and a power head device as described above. The drive shaft in the power head device is connected to the conveying device at one end away from the drive source, and the drive shaft is used to deliver power to the conveying device.

[0014] In some embodiments, the conveying device includes two sprockets and a plurality of chain plates, wherein one of the sprockets is fixedly connected to the drive shaft, and the chain plates are sequentially hinged to form an annular chain conveyor belt. The sprockets are provided with a plurality of notches in the circumferential direction, and the chain plates have protrusions that are adapted to the notches on the inner side of the conveyor belt.

[0027] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0028] This invention discloses a power head stabilizing structure for stabilizing the drive source 1 and drive shaft 3 in the power head, thereby reducing the axial stress, radial stress, and other directional stresses borne by the drive shaft 3 during operation. Axial stress causes axial tensile or compressive deformation of the drive shaft 3, while radial stress causes bending deformation. Stresses in other directions can be decomposed into axial and radial stresses, causing deformation of the drive shaft 3. By reducing the stress borne by the drive shaft 3, the deformation and fracture of the drive shaft 3 are delayed, thus extending its service life.

[0029] Referring to Figures 1 and 2, the stabilizing structure includes a support member 10 and a frame 5. The frame 5 is used to rotatably connect to the drive shaft 3 in a first direction, that is, to ensure that the axial extension direction of the drive shaft 3 is consistent with the first direction, the axial stress direction of the drive shaft 3 is consistent with the first direction, and the radial stress direction of the drive shaft 3 is consistent with the direction perpendicular to the first direction. The XX direction represents the first direction. During operation, the drive shaft 3 mainly bears axial and radial stresses, that is, it mainly bears stresses in the first direction and stresses perpendicular to the first direction. The support member 10 is fixedly connected to the frame 5 and the drive source 1 by fasteners 30. The fasteners 30 are configured to withstand stresses in the first direction and / or perpendicular to the first direction, thus distributing the stress borne by the drive shaft 3 during operation. It should be noted that whether the fasteners 30 bear stresses in the first direction or perpendicular to the first direction, they can reduce the stress on the drive shaft 3, achieving a stabilizing effect and delaying the deformation and fracture of the drive shaft 3.

[0030] In some embodiments, the fastener 30 is a bolt. A bolt, acting alone, can withstand both axial and radial stresses, and is easy to install and remove, making it widely applicable. The axial and radial stresses borne by the drive shaft 3 can be distributed to the bolt through force decomposition. That is, regardless of the bolt's installation direction or position, the bolt fastener 30 can effectively distribute stress, and thus distribute both axial and radial stresses on the drive shaft 3. Of course, in other embodiments, other fasteners 30 capable of withstanding axial and radial stresses, such as pins, can be used. Alternatively, in other embodiments, multiple fasteners 30 can be used in combination to meet the requirement of withstanding stresses along and / or perpendicular to the first direction.

[0031] In some embodiments, the support member 10 includes a first support member 10a and a second support member 10b. When the stabilizing structure is in the stabilizing power head state, the first support member 10a and the second support member 10b are located on opposite radial sides of the drive shaft 3. Providing two support members 10 improves the stability of the stabilizing head, ensures stress distribution on the drive shaft 3, and avoids excessively increasing the mass of the power head device.

[0032] Referring to Figures 1 and 2, in this embodiment, the drive shaft 3 is rotatably connected to the frame 5 in the left-right direction. That is, the axis of the drive shaft 3 is in the left-right direction. In this embodiment, the first direction is the left-right direction, and the direction perpendicular to the first direction refers to all directions perpendicular to the first direction in space, such as the up-down direction, the front-back direction perpendicular to the paper, and all other directions on the vertical plane enclosed by the up-down direction and the front-back direction.

[0033] This utility model also discloses a power head device, including a drive source 1, a drive shaft 3, and a power head stabilizing structure as described in any of the above embodiments, which improves the stability of the power head, delays the deformation and fracture of the drive shaft 3, and extends the service life of the drive shaft 3.

[0034] Generally, as shown in Figures 1 and 2, a bearing (not shown) needs to be installed at the connection between the drive shaft 3 and the frame 5 to improve the stability of the drive shaft 3. The bearing also bears stress during operation. In this embodiment, the support member 10 not only shares the stress borne by the drive shaft 3, delaying deformation and fracture, but also shares the stress borne by the bearing, thus protecting it.

[0035] For drive source 1, an integrated drive is generally adopted. Drive source 1 includes drive components such as a motor, gearbox, steering gear, and clutch, as well as a housing to accommodate all drive components. Support member 10 is connected between frame 5 and housing to prevent direct connection between support member 10 and drive components, thus avoiding interference with their use. The motor provides the power required for drive, the gearbox regulates speed, the steering gear adjusts the direction of power transmission, and the clutch engages and disengages the power transmission path. The coordinated use of various drive components meets different drive requirements.

[0036] Alternatively, drive source 1 can also employ a combined drive system. That is, drive source 1 uses independent drive components such as a motor, gearbox, steering gear, and clutch, each with its own housing. Support member 10 is fixedly connected between the housing of the drive component directly connected to drive shaft 3 and the frame 5. Specifically, when drive source 1 includes an independent motor and gearbox, the gearbox is connected between the motor output and drive shaft 3, the drive component directly connected to drive shaft 3 is the gearbox, and support member 10 is fixedly connected between the frame 5 and the gearbox housing. This ensures that the support member 10 is installed as close as possible to drive source 1, thus maximizing its role in sharing the stress on drive shaft 3.

[0037] In some embodiments, as shown in Figures 1 and 2, the power head device further includes a rotating mechanism 40, which includes a fixing member 2 and a connecting member 4. The fixing member 2 is fixedly connected to the drive source 1, and the connecting member 4 is rotatably mounted on the fixing member 2 and fixedly connected to the fastener 30. Specifically, the fixing member 2 can be fixedly mounted on the housing of the drive source 1 by welding or integral molding, and the connecting member 4 is rotatably engaged with the fixing member 2.

[0038] During installation, the support member 10 is first fixed to the connector 4 using fasteners 30, allowing the support member 10 to rotate relative to the fixed member 2 along with the connector 4, thus adjusting the posture of the support member 10. After the posture of the support member 10 is adjusted, it is then fixed to the frame 5 using fasteners 30, preventing the support member 10 from rotating with the connector 4. This design facilitates the installation and posture adjustment of the support member 10.

[0039] In this embodiment, the support member 10 includes a first support member 10a and a second support member 10b. The first support member 10a is positioned above the drive shaft 3, and the second support member 10b is positioned below the drive shaft 3. The second support member 10b is fixed to the connector 4 by fasteners 30, allowing the second support member 10b to rotate and adjust its posture with the connector 4 before it is fixedly connected to the frame 5.

[0040] In some embodiments, the support member 10 is connected to the drive source 1 by two or more fasteners 30, one of which is fixedly connected to the connector 4. Referring to Figures 1 and 2, in this embodiment, the second support member 10b is a bent rod. The second support member 10b is fixed to the housing of the drive source 1 by two fasteners 30. One fastener 30 fixes the second support member 10b to the connector 4, and the other fastener 30 directly fixes the second support member 10b to the housing of the drive source 1, thereby ensuring the connection strength between the second support member 10b and the drive source 1.

[0041] This utility model also provides a cigarette conveying line. Referring to Figure 3, the cigarette conveying line includes a conveying device 20 and a power head device as described in any of the above embodiments. The drive shaft 3 in the power head device has one end connected to the conveying device 20 away from the drive source 1, and the drive shaft 3 is used to supply power to the conveying device 20. Applying the above-mentioned power head device to the cigarette conveying line results in a long service life for the drive shaft 3, thereby ensuring production reliability and avoiding frequent power head maintenance and replacement, which would affect production.

[0042] In some embodiments, as shown in Figure 4, the conveying device 20 includes two sprockets 6 and several chain plates 8. One of the sprockets 6 is fixedly connected to the drive shaft 3. The chain plates 8 are sequentially hinged to form an annular chain conveyor belt. The sprocket 6 has several notches 7 circumferentially opened. The chain plates 8 have protrusions 9 that are adapted to the notches 7 facing the inside of the conveyor belt. The notches 7 on the sprocket 6 and the protrusions 9 on the chain plates 8 cooperate to improve the conveying stability of the entire conveying device 20.

[0043] In some embodiments, as shown in Figure 5, the conveying devices 20 are provided in two or more sets distributed along a first direction. In existing power head devices, the drive shaft 3 in the power head is used to drive multiple sets of conveying devices 20 simultaneously. This increases the load on the drive shaft 3 and the deformation stress it bears, making it more prone to deformation fracture. However, the cigarette conveying line in this embodiment uses a power head device with a robust structure. The deformation stress borne by the drive shaft 3 is distributed through fasteners 30, delaying deformation fracture and meeting the production requirements when multiple sets of conveying devices 20 are set up for cigarette conveying.

[0044] In some embodiments, the frame 5 includes a guide frame 51 and a fixed frame 52. Guide frames 51 are provided on both sides of the conveying device 20 along a first direction. The guide frames 51 extend along the conveying direction of the conveying device 20 and are rotatably connected to the drive shaft 3. The fixed frame 52 is fixedly connected between the guide frames 51 on both sides of the conveying device 20. The arrangement of the guide frames 51 and the fixed frame 52 improves the stability of the cigarette conveying and prevents the cigarettes from falling during conveying. Additionally, it provides multi-point support for the drive shaft 3, further improving its stability.

[0045] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0046] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0047] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
