[0047] The embodiment of the invention discloses a nozzle for cleaning a tobacco drum, which solves the problem that the drum wall structure of the existing tobacco drum is complex and it is inconvenient for operators to enter and exit the drum for cleaning.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] Example 1

[0050] See also Figures 1-8 , Figure 1 A schematic structural diagram of a nozzle for cleaning a tobacco drum provided by the first embodiment of the present invention; Figure 2 A schematic structural diagram of the top nozzle 6 provided in the first embodiment of the present invention; Figure 3 A schematic structural diagram of the fixing base 3 provided in the first embodiment of the present invention; Figure 4 A schematic structural diagram of a circumferential nozzle 2 provided in an embodiment of the present invention; Figure 5 A schematic structural diagram of a nozzle fixing sleeve 61 provided in a first embodiment of the present invention; Figure 6 A schematic structural diagram of a gland provided in accordance with a first embodiment of the present invention; Figure 7 A schematic structural diagram of a nozzle core 64 provided in a first embodiment of the present invention; Figure 8 This is a schematic structural diagram of the tapered sleeve 63 provided in the first embodiment of the present invention.

[0051] In this specific embodiment, the cleaning medium is water, and the direction of the water flow ejected from the incident tube 4 is forward, and the direction of the water flow forming an obtuse angle with the ejection direction is backward. The nozzle for cleaning the tobacco drum includes:

[0052] A nozzle body 1 capable of being embedded in the drum wall and having a first hollow cavity 8, the nozzle body 1 comprising a fixing base 3 connected to the nozzle body 1 at a first end and to the injection tube 4 at a second end, and a circumferential nozzle 2 arranged along the circumference of the nozzle body 1 and communicating with the outside and the first hollow cavity 8;

[0053] A mounting hole for installing the nozzle body 1 is provided on the drum wall, and one end of the nozzle body 1 in the mounting hole is connected to a power source, such as a cylinder, which pushes the nozzle body 1 out of the drum wall by a preset distance, so that water is sprayed backward through the circumferential nozzle 2 to automatically clean the drum wall, thereby improving cleaning efficiency and reducing labor costs.

[0054] The first hollow cavity 8 is symmetrically arranged along the center line of the nozzle body 1 to facilitate production and processing. Similarly, after installation, the center line of the fixing seat 3 coincides with the center line of the nozzle body 1, and the inner surface of the fixing seat 3 and the hollow cavity form a closed cavity for carrying water flow. The fixing seat 3 is preferably provided with an external thread on the outer wall, and the inner wall of the nozzle body 1 is provided with an internal thread to facilitate disassembly and assembly. In order to further facilitate disassembly and assembly, a threaded hole is provided at the center of the fixing seat 3 to facilitate fixation with the injection tube 4 (such as a water pipe), or an external sleeve is provided at the center of the fixing seat 3, and an external thread is provided on the outer wall of the sleeve to achieve fixation with the internal thread of the injection tube 4. The form of the thread can be set as needed.

[0055] A hollow pipe connecting the circumferential nozzle 2 and the first hollow cavity 8 is provided on the nozzle body 1 for installing the circumferential nozzle 2. The circumferential nozzle 2 is provided at the outlet end of the hollow pipe, and the circumferential nozzle 2 is preferably threadedly connected to the outlet end of the hollow pipe. The needs of cleaning the drum wall can be met by selecting different outlet hole sizes and water flow pressures of the circumferential nozzle 2. The spray direction of the circumferential nozzle 2 is at an obtuse angle to the spray direction of the injection pipe 4, thereby achieving the direction adjustment of the incident water flow and the outgoing water flow. The spray direction of the injection pipe 4 is consistent with the center line direction of the nozzle body, and the center line of the circumferential nozzle 2 is at a preset angle to the center line of the nozzle body. When the nozzle body 1 is vertically installed on the drum wall or other plate body, the wall or plate body on which the nozzle body 1 is installed can be cleaned by reverse cleaning, and the cleaning area can be adjusted according to the extended length of the nozzle body 1.

[0056] The nozzle body 1 is preferably configured as a conical shell, with the circumferential nozzles 2 disposed along the circumferential sidewall of the conical shell. The angle between the centerline of the circumferential nozzle 2 and the centerline of the nozzle body 1 is the same as the cone angle of the conical shell, to facilitate the production and processing of the circumferential nozzles 2. It is understood that when there are multiple circumferential nozzles 2, the centerlines of the multiple circumferential nozzles 2 intersect at the same point on the centerline of the conical shell, and the angles between adjacent circumferential nozzles 2 are the same, so that they are evenly disposed along the circumference of the conical shell.

[0057] The tobacco drum cleaning nozzle provided by the present invention is used. When in use, the nozzle body 1 is embedded in the drum wall. The nozzle body 1 and the fixing seat 3 form a hollow cavity, and the injection tube 4 is connected to the hollow cavity. A circumferential nozzle 2 is provided on the circumference of the nozzle body 1. The injection direction of the circumferential nozzle 2 forms an obtuse angle with the injection direction of the injection tube 4, so that the medium enters the first hollow cavity 8 after passing through the injection tube 4 and is ejected backward through the circumferential nozzle 2 to clean the drum wall. This configuration eliminates the need for manual entry into the drum for manual cleaning. The nozzle body 1 set on the drum wall can automatically clean the drum wall, the discharge panel, and the feed panel in the reverse direction, thereby improving maintenance efficiency and reducing labor costs.

[0058] In order to prevent the material in the tobacco drum from entering the interior through the mounting hole, a radial annular wall is provided around the circumferential side wall of the nozzle body 1. The radial annular wall is continuously arranged around the circumference of the nozzle body 1. A sealing member 5 is provided around the side of the radial annular wall close to the fixing seat 3. The sealing member 5 is bonded to the radial annular wall so that when the nozzle body 1 is embedded, it is sealed with the surface of the inlay. The sealing member 5 can be set as a sealing rubber pad.

[0059] On the basis of the above embodiments, a top nozzle 6 is further provided on the nozzle body 1. The top nozzle 6 includes:

[0060] A nozzle fixing sleeve 61 fixed to the nozzle body 1 and having a second hollow cavity 611, a gland 62 fixedly connected to the nozzle fixing sleeve 61, a nozzle core 64 axially extending through the second hollow cavity 611 and the end wall of the gland 62, and an elastic member 65 sleeved on the nozzle core 64, with its two ends respectively abutting against the first end 643 of the nozzle core 64 and the gland 62;

[0061] The nozzle fixing sleeve 61 has a fixing sleeve inlet 613 at one end close to the first hollow cavity 8 for cooperating with the first end 643 , and a pressure cover outlet 621 is provided on the circumferential side wall of the pressure cover 62 in contact with the nozzle core 64 .

[0062] The nozzle retaining sleeve 61 is configured as a cylindrical sleeve with external threads on its outer wall. The nozzle body 1 is provided with a mounting hole for mounting the nozzle retaining sleeve 61, and the mounting hole is internally threaded to facilitate assembly and disassembly of the two. The end wall of the nozzle retaining sleeve 61 is flush with the end wall of the nozzle body 1, maintaining a neat appearance. A second hollow cavity 611 is positioned along the centerline of the nozzle retaining sleeve 61. The outer end wall of the nozzle retaining sleeve 61 is provided with an inwardly extending mounting groove 612 for mounting the gland 62. The inner wall of the mounting groove 612 is internally threaded. The gland 62 is positioned within the mounting groove 612 and is threadedly connected thereto for securement. A fixing sleeve inlet 613 is provided on the end wall of the nozzle fixing sleeve 61 on one side away from the pressure cover 62. The inlet is connected to the first hollow cavity 8 to facilitate the water flow to enter the second hollow cavity 611. The shape of the fixing sleeve inlet 613 is adapted to the structure of the nozzle core 64. In one embodiment, the fixing sleeve inlet 613 is configured as a tapered hole with a diameter increasing from the outside to the inside, thereby facilitating the guidance of the incoming water flow, reducing the water flow pressure at the fixing sleeve inlet 613, and allowing the water flow to pass through the fixing sleeve inlet 613 quickly.

[0063] The nozzle core 64 axially passes through the second hollow cavity 611 and the gland 62, and the side end walls of the nozzle core 64 are flush with the side end walls of the nozzle fixing sleeve 61. The gland 62 is provided with a core mounting hole for mounting the nozzle core 64 and gland outlets 621. The gland outlets 621 are preferably evenly distributed along the circumference, and their number and location are not limited.

[0064] The nozzle core 64 is capable of moving axially. An elastic member 65 is sleeved on the nozzle core 64. One end of the elastic member 65 contacts the inner end wall of the pressure cap 62, and the other end of the elastic member 65 abuts against the first end 643 of the nozzle core 64. When the first end 643 moves axially under the pressure of the water flow, it presses and contracts the elastic member 65. The water flow overcomes the elastic force of the elastic member 65 and enters the second hollow cavity 611 through the fixed sleeve inlet 613, and flows out through the pressure cap outlet 621 to achieve spraying. When in use, the elastic coefficient of the elastic member 65 is set according to the required water outlet pressure. The elastic member 65 is preferably set as a spring. It can be understood that the first end 643 is matched with the structure of the fixed sleeve inlet 613, and is preferably set as a cone.

[0065] The specific operation process is:

[0066] Water flows through the inlet tube 4 on the fixed seat 3 into the first hollow cavity 8 and is ejected backwards through the circumferential nozzle 2. At the same time, the water pressure inside the first hollow cavity 8 gradually increases. When the water pressure inside the first hollow cavity 8 is greater than the elastic force of the elastic member 65, the water pushes the nozzle core 64 to move axially, forming a gap between the first end 643 and the fixed sleeve inlet 613. Water flows through the fixed sleeve inlet 613 into the second hollow cavity 611 and is ejected forwards through the gland outlet 621. Thus, by respectively setting the circumferential nozzle 2 and the top nozzle 6 to achieve the backward and forward ejection of water, the nozzle can clean the cylinder wall in multiple directions, expand the cleaning range, and further improve the cleaning efficiency.

[0067] Furthermore, the nozzle core 64 includes a first end 643, a neck 642, and a second end 641, which are connected in sequence. The neck 642 and the first end 643 are preferably integrally formed, and the second end 641 and the neck 642 are preferably threadedly connected. External threads are provided on the outer wall of the neck 642, and the second end 641 is provided with a mounting hole for the neck 642, which is fixed to the neck 642. The diameter of the neck 642 is smaller than that of the first end 643 and the second end 641. The gland 62 is provided with a mounting groove 622 for mounting the second end 641. A through hole is provided below the mounting groove 622, extending axially through the gland 62. The neck 642 is disposed within the second hollow cavity 611 through the through hole. The bottom wall of the mounting groove 622 is provided with a gland outlet 621, which is arranged parallel to the axial direction. During installation, the elastic member 65 is first placed on the neck 642 so that one end thereof abuts against the end wall of the first end portion 643, and then the pressure cap 62 is installed so that the other end of the elastic member 65 abuts against the inner end wall of the pressure cap 62, and the pressure cap 62 is fixed to the nozzle fixing sleeve 61 via a threaded connection. The neck 642 passes through the through hole, and the second end portion 641 is set in the installation groove 622 and threadedly connected to the neck 642.

[0068] In one embodiment, the gland outlet 621 is disposed on the bottom wall of the mounting groove 622 and is spaced from the centerline of the gland 62 at a distance less than or equal to the radius of the second end portion 641. This allows the gland outlet 621 to be sealed when the end wall of the second end portion 641 contacts the bottom wall of the mounting groove 622. When the nozzle core 64 moves axially under water pressure, the end wall of the second end portion separates from the bottom wall of the mounting groove 622, allowing the gland outlet 621 to communicate with the outside world. Water then flows through the second hollow cavity 611 and the gland outlet 621, exiting along the circumference of the second end portion 641.

[0069] like Figure 8Figure 6 shows a schematic diagram of the conical sleeve structure, with (a) showing a top view and (b) showing a side view. To increase the spray range of the top nozzle 6, the circumferential sidewall of the second end portion 641 is removably fixedly connected to the conical sleeve 63. Accordingly, the structure of the mounting groove 622 is compatible with that of the conical sleeve 63 to facilitate installation and positioning. The circumferential sidewall of the second end portion 641 is provided with external threads, while the inner wall of the center hole of the conical sleeve 63 is provided with internal threads. After passing through the gland outlet 621, water is ejected along the circumference of the conical sleeve 63.

[0070] Example 2

[0071] like Figure 9 As shown, Figure 9 This is a schematic diagram of the structure of a nozzle for cleaning a tobacco drum provided by the second embodiment of the present invention. In this specific embodiment, the present invention provides a nozzle for cleaning a tobacco drum, comprising:

[0072] A nozzle body 1 is embedded in the drum wall and is provided with a first hollow cavity 8. The nozzle body 1 includes a fixing base 3 connected to the nozzle body 1 at a first end and to the injection tube 4 at a second end, and a circumferential nozzle 2 arranged along the circumference of the nozzle body 1 and communicating with the outside and the first hollow cavity 8.

[0073] The fixing seat 3 is connected to the injection tube 4 and the first hollow cavity 8. The injection direction of the circumferential nozzle 2 forms an obtuse angle with the injection direction of the injection tube 4. The medium entering the first hollow cavity 8 through the injection tube 4 is reflected by the inner wall of the first hollow cavity 8 and ejected backward from the circumferential nozzle 2 to clean the cylinder wall.

[0074] An outlet is provided on the nozzle body 1 and has a spraying direction that is the same as the incident direction of the medium. The outlet is communicated with the first hollow cavity 8 .

[0075] Among them, the nozzle body 1, circumferential nozzle 2 and other structures that are the same as those in Example 1 can refer to Example 1 and will not be repeated here. An outlet pipe 7 is set on the nozzle body 1, and the diameter of the outlet pipe 7 can match the diameter of the inlet pipe 4. Water flows through the first hollow cavity 8 and the outlet pipe 7 and is sprayed out. In one embodiment, the end of the outlet pipe 7 is provided with an external thread, and the diameter of the end of the outlet pipe 7 matches the threaded hole of the fixing seat 3 in Example 1 to achieve the combined use of the two nozzles. At the same time, when used in combination, the circumferential nozzle 2 in this embodiment is set between the circumferential nozzles 2 in Example 1 by setting the screw advance amount of the thread to achieve a staggered arrangement and clean different directions.

[0076] Example 3

[0077] like Figure 10 、 11 As shown, Figure 10 A schematic structural diagram of a nozzle for cleaning a tobacco drum provided by a third embodiment of the present invention; Figure 11 This is a schematic structural diagram of a fixing base 3 provided in the third embodiment of the present invention. In this embodiment, the nozzle for cleaning the tobacco drum provided by the present invention includes:

[0078] A nozzle body 1 capable of being embedded in the drum wall and having a first hollow cavity 8, the nozzle body 1 comprising a fixing base 3 connected to the nozzle body 1 at a first end and to the injection tube 4 at a second end, and a circumferential nozzle 2 arranged along the circumference of the nozzle body 1 and communicating with the outside and the first hollow cavity 8;

[0079] The fixing seat 3 is connected to the injection tube 4 and the first hollow cavity 8. The injection direction of the circumferential nozzle 2 forms an obtuse angle with the injection direction of the injection tube 4. The medium entering the first hollow cavity 8 through the injection tube 4 is ejected backward through the circumferential nozzle 2 to clean the cylinder wall.

[0080] The fixing seat 3 includes a fixing portion 31 for fixing to the nozzle body 1 and a rotating portion 32 rotatably connected to the fixing portion 31 . The rotation axis of the rotating portion 32 coincides with the center line of the nozzle body 1 , so as to drive the nozzle body 1 to rotate along the center line under the drive of the medium.

[0081] Among them, the nozzle body 1, circumferential nozzle 2 and other structures that are the same as those in Example 1 can refer to Example 1. Preferably, the nozzle body 1 also includes an outlet provided on the nozzle body 1 and the injection direction is the same as the incident direction of the medium. The outlet is connected to the first hollow cavity 8. The specific structure and connection relationship can be referred to Example 2 and will not be repeated here.

[0082] The fixed portion 31 is threadedly connected to the nozzle body 1, and the rotation axis of the rotating portion 32 coincides with the centerline of the fixed portion 31. After the water enters the first hollow cavity 8, it is ejected along the outlet and circumferential nozzle 2. The rotation speed of the nozzle body 1 is adjusted by adjusting the water flow pressure. Furthermore, a bearing 33 is provided between the fixed portion 31 and the rotating portion 32. The inner ring of the bearing 33 is fixed to the outer wall of the rotating portion 32, and the outer ring of the bearing 33 is fixed to the inner wall of the fixed portion 31. This achieves a rotational connection between the fixed portion 31 and the rotating portion 32. A seal, such as a gasket, is provided between the fixed portion 31 and the rotating portion 32 for sealing. The bearing 33 can be a ball bearing or other type of bearing, and the bearing model is set as needed.

[0083] The bottom of the rotating part 32 is provided with an external thread or an internal thread for externally connecting the shooting tube 4, which can be set as needed. Among them, the fixing seat 3 in the third embodiment can also be set in the first and second embodiments for replacement, and the various embodiments can refer to each other.

[0084] The present invention also provides a combined nozzle, comprising:

[0085] The tobacco roller cleaning nozzle as described in any one of Example 1, the tobacco roller cleaning nozzle as described in any one of Example 2 and / or the tobacco roller cleaning nozzle as described in any one of Example 3 connected in sequence; in one embodiment, the combined nozzle includes: a tobacco roller cleaning nozzle as described in any one of Example 1 and one or several tobacco roller cleaning nozzles as described in any one of Example 2; or a tobacco roller cleaning nozzle as described in any one of Example 1 and one or several tobacco roller cleaning nozzles as described in any one of Example 3; or a tobacco roller cleaning nozzle as described in any one of Example 1, one or several tobacco roller cleaning nozzles as described in any one of Example 2 and one or several tobacco roller cleaning nozzles as described in any one of Example 3, all of which are within the scope of protection of the present invention.

[0086] The tobacco drum cleaning nozzle provided by the present invention is used. When in use, the nozzle body 1 is embedded in the drum wall. The nozzle body 1 and the fixing seat 3 form a hollow cavity, and the injection tube 4 is connected to the hollow cavity. A circumferential nozzle 2 is provided on the circumference of the nozzle body 1. The injection direction of the circumferential nozzle 2 forms an obtuse angle with the injection direction of the injection tube 4, so that the medium enters the first hollow cavity 8 after passing through the injection tube 4 and is ejected backward through the circumferential nozzle 2 to clean the drum wall. This configuration eliminates the need for manual entry into the drum for manual cleaning. The nozzle body 1 set on the drum wall can automatically clean the drum wall, the discharge panel, and the feed panel in the reverse direction, thereby improving maintenance efficiency and reducing labor costs.

[0087] Taking a stem thread feeder as an example, the limited internal drum space, poor maintenance environment, and slippery drum walls can cause operators to fall during maintenance, necessitating on-site supervision by both upstream and downstream process personnel to mitigate safety hazards. Installing cleaning nozzles on the inlet and outlet panels and discharge hood addresses the sticky material produced by the stem thread feeder, which easily adheres to the panels, creating numerous maintenance blind spots. Manual water rinsing is difficult, requiring repeated maintenance. Secondly, this addresses the limited internal drum space and the numerous, multi-faceted raking spikes and guide plates on the drum's inner wall, which not only create inconvenience for operators entering and exiting the drum but also increase safety hazards. Thirdly, this addresses the need for on-site supervision by upstream and downstream process personnel during drum maintenance. Unlike other drum rehydration equipment, the stem thread feeder utilizes a "one person, one machine" production model for each process. This hinders optimal human resource allocation and impacts maintenance schedules in other processes.

[0088] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
