Description

Technical Field

[0001] The utility model relates to the technical field of tobacco equipment maintenance, and more particularly to a rake nail used for an air selector of a cigarette equipment. Background Art

[0002] In tobacco processing, a SIROX heating and humidification system is typically installed before the downstream tobacco dryer. Its primary function is to use high-temperature steam to rapidly increase the moisture content of the cut tobacco, allowing it to expand rapidly and then dry and shape it in the dryer. The SIROX heating and humidification system primarily consists of a humidification system, a feed air lock, a moisture removal system, and an electrical control system. The humidification system terminates in a cylindrical housing and an air separator with rotating rake pins. Steam required for production and water and steam required for cleaning are supplied and discharged through the rake pins.

[0003] At present, during the rotating work and rotating cleaning process of the rake nails, the steam and water sprayed by the rake nails cannot completely cover the inner wall of the equipment casing, causing the tobacco material to adhere to the inner wall of the equipment casing. During the production process, the adhered material is in a high temperature and high humidity environment for a long time and gradually forms wet clumps. After falling into the next silk drying process, it is difficult to be dried. The wet clumps will cause the production of yellow spot smoke in subsequent processes, thereby causing serious process quality problems.

[0004] Therefore, how to provide a rake nail for the air separator of cigarette equipment has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] According to a first aspect of the present invention, there is provided a rake nail for a wind selector of a cigarette making device, comprising: a cavity is provided inside the rake nail, and the cavity is used to communicate with an external steam source;

[0007] The rake nail is provided with an inclined spray hole and a first horizontal spray hole. The inclined spray holes are arranged on the outer peripheral wall of the rake nail and are arranged at intervals along the circumference of the rake nail. The first horizontal spray hole is arranged at the first end of the rake nail. The inclined spray hole and the first horizontal spray hole are both connected to the cavity.

[0008] Optionally, the angle formed by the axis of the inclined spray hole and the axis of the first horizontal spray hole is 60 degrees.

[0009] Optionally, the inclined spray hole is extended toward the first end of the rake nail.

[0010] Optionally, an inner diameter of the inclined injection hole is gradually reduced from a first end of the inclined injection hole communicating with the cavity to a second end of the inclined injection hole.

[0011] Optionally, the rake nail is further provided with a second horizontal spray hole, which is arranged at intervals on the outer peripheral wall of the rake nail, and there is a distance between the second horizontal spray hole and the inclined spray hole.

[0012] Optionally, a connecting rod is provided on the second end of the rake nail, and an external thread is provided on the outer peripheral wall of the connecting rod.

[0013] Optionally, two clamping grooves are further provided on the outer peripheral wall of the rake nail, and the two clamping grooves are arranged opposite to each other.

[0014] The beneficial effects of the present invention are:

[0015] The utility model provides inclined spray holes on the outer peripheral wall of the rake nail and at intervals along the circumference of the rake nail, and a first horizontal spray hole is provided at the first end of the rake nail, and both the inclined spray hole and the first horizontal spray hole are connected to the cavity. During use, an external steam source introduces steam and water into the cavity inside the rake nail, causing the pressure inside the cavity to change, and the steam and water to be discharged from the inclined spray hole and the first horizontal spray hole. Due to the provision of the inclined spray holes, the spray range of the steam and water can be increased, so that the steam and water act on the inner wall of the equipment housing, and can clean tobacco material adhering to the inner wall, thereby ensuring that material does not adhere to the inner wall of the equipment housing during the production process, eliminating the generation of wet clumps, avoiding the process hidden danger of forming yellow-spotted cigarettes, and effectively improving the quality of the finished cigarettes.

[0025] like Figures 1 to 2 As shown, an embodiment of the present invention provides a rake nail for a winnowing device of a cigarette making device, comprising: a rake nail 1 having a cavity 2 provided therein, the cavity 2 being used for communicating with an external steam source.

[0026] The rake nail 1 is provided with an inclined spray hole 3 and a first horizontal spray hole 4. The inclined spray hole 3 is arranged on the outer peripheral wall of the rake nail 1 and is arranged at intervals along the circumference of the rake nail 1. The first horizontal spray hole 4 is arranged at the first end of the rake nail 1. The inclined spray hole 3 and the first horizontal spray hole 4 are both connected to the cavity 2.

[0027] When in use, the rake nail 1 is driven to rotate by the rotating shaft of the air selector, and an external steam source introduces steam and water into the cavity 2 inside the rake nail 1. The pressure inside the cavity 2 changes, and the steam and water are discharged from the inclined injection hole 3 and the first horizontal injection hole 4, and act on the tobacco, causing the tobacco to heat up and expand rapidly.

[0028] When maintenance is required after production, an external steam source introduces steam and water into the cavity 2 inside the rake spike 1. The pressure inside the cavity 2 changes, and the steam and water are discharged from the inclined injection hole 3 and the first horizontal injection hole 4. Due to the setting of the inclined injection hole 3, the injection range of the steam and water can be increased, so that the steam and water act on the inner wall of the equipment housing and can clean the tobacco material adhering to the inner wall.

[0029] The utility model is characterized in that the inclined injection holes 3 are arranged on the outer peripheral wall of the rake nail 1 and are spaced apart along the circumference of the rake nail 1, and the first horizontal injection hole 4 is arranged at the first end of the rake nail 1, and both the inclined injection hole 3 and the first horizontal injection hole 4 are connected to the cavity 2. During use, an external steam source introduces steam and water into the cavity 2 inside the rake nail 1, the internal pressure of the cavity 2 changes, and the steam and water are discharged from the inclined injection hole 3 and the first horizontal injection hole 4. Due to the arrangement of the inclined injection hole 3, the injection range of the steam and water can be increased, so that the steam and water act on the inner wall of the equipment housing, and can clean tobacco materials adhering to the inner wall, thereby ensuring that materials do not adhere to the inner wall of the equipment housing during the production process, eliminating the generation of wet clumps, avoiding the process hidden danger of forming yellow-spotted cigarettes, and effectively improving the quality of the finished cigarettes.

[0030] In one embodiment of the present invention, the rake nails for the air separator of the cigarette making equipment are as follows: Figure 2 As shown, the angle formed by the axis of the inclined spray hole 3 and the axis of the first horizontal spray hole 4 is 60 degrees.

[0031] Specifically, when the angle formed by the axis of the inclined injection hole 3 and the axis of the first horizontal injection hole 4 is 60 degrees, the steam and water sprayed from the inclined injection hole 3 can move toward the inner wall of the device housing with a certain amplitude, and the spray range of the steam and water can be made larger, so as to achieve the cleaning of the tobacco material adhered to the inner wall of the equipment housing.

[0032] It should be noted that the angle formed by the axis of the inclined injection hole 3 of the shell of the present invention and the axis of the first horizontal injection hole 4 can also be other degrees, and the angle formed by the axis of the inclined injection hole 3 and the axis of the first horizontal injection hole 4 is between 25 degrees and 75 degrees.

[0033] In one embodiment of the present invention, the rake nails for the air separator of the cigarette making equipment are as follows: Figure 2 As shown, the inclined injection hole 3 extends toward the first end of the rake nail 1. This arrangement enables the steam and water injected from the inclined injection hole 3 to move toward the first end of the rake nail 1 and be injected onto the inner wall of the device casing, thereby increasing the injection range of the steam and water.

[0034] In one embodiment of the rake nail for the air selector of the cigarette making equipment of the present invention, the inner diameter of the inclined injection hole 3 is gradually reduced from the first end of the inclined injection hole 3 communicating with the cavity 2 to the second end of the inclined injection hole 3 .

[0035] Specifically, the inner diameter of the inclined injection hole 3 is a variable diameter setting, and the inner diameter of the inclined injection hole 3 close to the outer peripheral wall of the rake nail 1 is smaller than the inner diameter of the inclined injection hole 3 close to the inner peripheral wall of the rake nail 1, so that the steam and water inside the cavity 2 increase in pressure after entering the inclined injection hole 3, thereby further increasing the injection range of the steam and water, and can also improve the cleaning efficiency of the tobacco material adhered to the inner wall of the equipment casing, ensuring that the tobacco material adhered to the inner wall of the equipment casing can be cleaned.

[0036] In one embodiment of the present invention, the rake nails for the air separator of the cigarette making equipment are as follows: Figures 1 to 2 As shown, the rake nail 1 is further provided with a second horizontal spray hole 5 , which is arranged at intervals on the outer peripheral wall of the rake nail 1 , and there is a distance between the second horizontal spray hole 5 and the inclined spray hole 3 .

[0037] Specifically, the axis of the second horizontal spray hole 5 is perpendicular to the axis of the first horizontal spray hole 4 .

[0038] The utility model arranges the second horizontal spray holes 5 at intervals on the outer peripheral wall of the rake nail 1, and there is a distance between the second horizontal spray holes 5 and the inclined spray holes 3, so that the tobacco material adhered to the inner wall of the device housing can be cleaned through the multiple second horizontal spray holes 5, so that the rake nail 1 can fully cover the inner wall of the device housing with steam and water through the first horizontal spray holes 4, the second horizontal spray holes 5 and the inclined spray holes 3.

[0039] In one embodiment of the present invention, the rake nails for the air separator of the cigarette making equipment are as follows: Figures 1 to 2 As shown, a connecting rod 6 is provided on the second end of the rake nail 1, and an external thread 7 is provided on the outer peripheral wall of the connecting rod 6. This arrangement enables the rake nail 1 to be stably installed on the air separator through the connecting rod 6, ensuring the stability and safety of the rake nail 1 during operation.

[0040] In one embodiment of the present invention, the rake nails for the air separator of the cigarette making equipment are as follows: Figures 1 to 2 As shown, in order to further increase the installation stability of the rake nail 1, two clamping grooves 8 are further provided on the outer peripheral wall of the rake nail 1, and the two clamping grooves 8 are arranged opposite to each other.

[0041] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention.
