Description

Technical Field

[0001] This utility model relates to the field of cigarette machinery and equipment technology, and more specifically, to a transmission device for cigarette machinery and equipment. Background Technology

[0002] There are various transmission methods in cigarette winding equipment. Among them, the power input shaft of the spider hand's transmission device is a synchronous belt drive. The pulley and shaft are connected by a key, which has a weak load-bearing capacity and the pulley is too heavy. Due to inertia, the impact force on the key or keyway is large when starting and stopping, often resulting in keyway wear or key shearing. This directly causes the transmission device to run off track, affecting quality and operation. In addition, sometimes even a slight misalignment can cause the cigarette to be squeezed but not fall off, leaving an indentation. This requires repeated adjustments and repositioning to replace the pulley and drive shaft. The disassembly and assembly are extensive, time-consuming, and require frequent replacement of spare parts, which is uneconomical, inconvenient, and increases the labor intensity of the operators.

[0003] Therefore, how to provide a transmission device for cigarette making equipment has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a transmission device in cigarette manufacturing equipment.

[0005] According to a first aspect of the present invention, a transmission device for cigarette making equipment is provided, comprising: a pulley, a transmission assembly, and a locking assembly;

[0006] The pulley includes a hub, a toothed ring, and a web. Both ends of the web are connected to the hub and the toothed ring, and the web is provided with through holes. The inner wall of the hub is provided with multiple slots.

[0007] The transmission assembly includes a transmission shaft, a mounting groove, and a fixing key. The mounting groove is disposed on the first end of the transmission shaft and is evenly spaced along the outer peripheral wall of the transmission shaft. The fixing key is inserted into the mounting groove and the retaining groove respectively.

[0008] In the working state, the drive shaft is inserted into the hub, the locking assembly abuts against the slot, and the locking assembly is connected to the first end of the drive shaft.

[0009] Optionally, there are 6 through holes, which are evenly spaced along the circumference of the web.

[0010] Optionally, a worm gear is provided on the drive shaft.

[0011] Optionally, the transmission assembly further includes a connecting rod connected to the second end of the transmission shaft, wherein the diameter of the connecting rod is larger than the diameter of the transmission shaft, and the worm gear is sleeved on the connecting rod.

[0027] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a transmission device for cigarette making equipment, including: pulley 1, transmission assembly 2 and locking assembly 3.

[0028] The pulley 1 includes a hub 11, a toothed ring 12, and a web 13. Both ends of the web 13 are connected to the hub 11 and the toothed ring 12, and the web 13 is provided with through holes 14. The inner wall of the hub 11 is provided with multiple slots 15.

[0029] The transmission assembly 2 includes a transmission shaft 21, a mounting groove, and a fixing key 22. The mounting groove is located on the first end of the transmission shaft 21 and is evenly spaced along the outer peripheral wall of the transmission shaft 21. The fixing key 22 is inserted into the mounting groove and the retaining groove 15 respectively.

[0030] Specifically, the pulley 1 is connected to the belt through an external toothed ring 12. Due to the meshing of the toothed ring 12 with the belt, the stability of the transmission can be guaranteed.

[0031] There are four fixing keys 22 and four slots 15. The slots 15 are evenly spaced along the inner wall of the hub 11, and the fixing keys 22 are evenly spaced along the outer peripheral wall of the drive shaft 21.

[0032] In the working state, the drive shaft 21 is inserted into the hub 11, the locking component 3 abuts against the slot 15, and the locking component 3 is connected to the first end of the drive shaft 21.

[0033] This invention connects both ends of the web plate 13 to the hub 11 and the toothed ring 12, and provides through holes 14 on the web plate 13. Mounting grooves are provided on the first end of the drive shaft 21, and are evenly spaced along the outer periphery of the drive shaft 21. Fixing keys 22 are inserted into the mounting grooves and retaining slots 15 respectively. In the working state, the drive shaft 21 is inserted into the hub 11, and multiple fixing keys 22 are inserted into the mounting grooves and retaining slots 15 respectively, achieving the purpose that the rotation of the drive shaft 21 can drive the driven pulley 1 to rotate. This improves the impact resistance and load-bearing capacity, and allows the locking assembly 3 to abut against the retaining slot 15. The locking assembly 3 is also connected to the first end of the drive shaft 21, preventing the rotating shaft from separating from the driven pulley 1 during operation. Furthermore, by providing through holes 14 on the web plate 13, the weight of the parts is reduced without compromising their functionality, alleviating the problem of excessive impact on the transmission connection due to high inertia during start-up and shutdown.

[0034] In one embodiment of the transmission device for cigarette rolling equipment of this utility model, such as Figure 1 As shown, there are 6 through holes 14, which are evenly spaced along the circumference of the web plate 13. This arrangement can further reduce the weight of the pulley 1 and reduce the problem of excessive impact on the transmission connection during start-up and shutdown.

[0035] Furthermore, a worm gear 4 is provided on the drive shaft 21.

[0036] In one embodiment of the transmission device for cigarette rolling equipment of this utility model, such as Figure 1 and Figure 2 As shown, the transmission assembly 2 also includes a connecting rod 23, which is connected to the second end of the transmission shaft 21, and the diameter of the connecting rod 23 is larger than the diameter of the transmission shaft. The worm gear 4 is sleeved on the connecting rod 23.

[0037] This invention connects the connecting rod 23 to the second end of the transmission shaft 21, and makes the diameter of the connecting rod 23 larger than the diameter of the transmission shaft. This allows the fixing key 22 on the transmission shaft 21 to engage with the mounting groove and the slot 15, thereby restricting the lateral movement of the pulley 1 through the connecting rod 23. This increases the stability and safety of the transmission device for cigarette equipment during operation.

[0038] In one embodiment of the transmission device for cigarette rolling equipment of this utility model, a threaded rod 24 is provided on the first end of the transmission shaft 21.

[0039] The locking assembly 3 includes a fixing nut 31, the outer diameter of which is larger than the inner diameter of the hub 11. The fixing nut 31 is threadedly connected to the threaded rod 24. This arrangement, under the combined action of the fixing nut 31 and the connecting rod 23, provides a restriction on the lateral movement of the pulley 1.

[0040] In one embodiment of the transmission device for cigarette rolling equipment of this utility model, such as Figure 1 and Figure 2 As shown, the locking assembly 3 also includes a backstop washer 32, which is sleeved on the drive shaft 21 and located between the fixing nut 31 and the pulley 1.

[0041] This utility model, by sleeved with a backstop washer 32 on the transmission shaft 21 and positioned between the fixing nut 31 and the pulley 1, enables the transmission device of this utility model for cigarette equipment to maintain a stable and anti-loosening effect under vibration, impact and high-speed conditions.

[0042] In one embodiment of the transmission device for cigarette rolling equipment of this utility model, such as Figure 1 and Figure 2 As shown, the anti-reverse washer 32 includes a washer body, an outer ring thrust plate 33 and an inner ring thrust plate. The outer ring thrust plates 33 are respectively disposed on both sides of the outer edge of the washer body, and the inner ring thrust plate is disposed inside the washer body. The outer ring thrust plates 33 are engaged with the slot 15, and the inner ring thrust plate abuts against the drive shaft 21.

[0043] This invention features outer ring thrust plates 33 disposed on both sides of the outer edge of the washer body, and inner ring thrust plates disposed inside the washer body. In the working state, the anti-loosening washer 32 is fitted onto the drive shaft 21. At this time, the inner ring thrust plates abut against the drive shaft 21, and the outer ring thrust plates 33 engage with the slots 15. This structure does not rely on friction and can maintain a stable anti-loosening effect under vibration, impact, and high-speed conditions. It also reduces the need for frequent maintenance and extends the service life of the equipment.

[0044] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
