[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 3 As shown, Figure 1 , Figure 2 and Figure 3 The three-dimensional structure diagram, explosion diagram and cross-sectional view of the nozzle fixing device provided by an embodiment of the utility model are shown respectively. Figure 3 This is merely an example of how the nozzle 101 is installed in the nozzle installation hole 2 , and does not limit the installation position of the nozzle 101 .

[0032] In this embodiment, the nozzle fixing device includes:

[0033] A spherical fixing seat 1, wherein the spherical fixing seat 1 is provided with a nozzle mounting hole 2 along its axial direction, and the nozzle mounting hole 2 is used to accommodate the nozzle 101;

[0034] A first fixing frame 3 and a second fixing frame 4, both of which are provided with a circular hole 5, the diameter of the circular hole 5 is smaller than the diameter of the spherical fixing seat 1, the spherical fixing seat 1 is sandwiched between the two circular holes 5, and the spherical fixing seat 1 can rotate in the circular hole 5;

[0035] A locking member is provided between the first fixing frame 3 and the second fixing frame 4, and is used to lock the relative position between the first fixing frame 3 and the second fixing frame 4, so as to clamp the spherical fixing seat 1;

[0036] The adjusting handle 7 is detachably connected to the spherical fixing seat 1 .

[0037] With this technical solution, the nozzle 101 is installed in the nozzle mounting hole 2 by setting a spherical fixing seat 1, and the spherical fixing seat 1 is rotatably installed in the circular hole 5 of the first fixing frame 3 and the second fixing frame 4. The direction of the nozzle mounting hole 2 can be adjusted by rotating the spherical fixing seat 1, thereby adjusting the spray angle of the nozzle 101. In addition, an adjustment handle 7 is detachably provided on the spherical fixing seat 1. The operator can apply a force to the spherical fixing seat 1 by holding the adjustment handle 7 to drive the spherical fixing seat 1 to rotate in the circular hole 5, so that the direction of the nozzle mounting hole 2 can be further adjusted to avoid the nozzle mounting hole 2 of the spherical fixing seat 1 from being offset during the installation or locking of the spherical fixing seat 1, so as to ensure the spray angle of the nozzle 101, thereby effectively improving the uniformity of the dressing of the tobacco leaves inside the feeding barrel.

[0038] Optionally, in this embodiment, the nozzle 101 is arranged in the nozzle mounting hole 2 by interference fit to enhance the installation firmness of the nozzle 101. Of course, in other embodiments, the nozzle can also be threadedly connected to the nozzle mounting hole 2 to fix the nozzle in the nozzle mounting hole 2.

[0039] Furthermore, the adjustment handle 7 includes a rod portion 71 and a handle portion 72 , the extension directions of the rod portion 71 and the handle portion 72 are perpendicular to each other, one end of the rod portion 71 is connected to the middle of the handle portion 72 , and the other end of the rod portion 71 is threadedly connected to the spherical fixing seat 1 .

[0040] Specifically, in this embodiment, a threaded hole is provided at the outer end of the spherical fixing seat 1, and an external thread is provided at the front end of the rod portion 71. The front end of the rod portion 71 can be inserted into the threaded hole and threadedly connected with the threaded hole. When in use, the operator can hold the handle portion 72 to rotate the spherical fixing seat 1 to adjust the direction of the nozzle mounting hole 2.

[0041] With this technical solution, when the locking member is not completely loosened, that is, the locking member provides a certain clamping force to the first fixing frame 3 and the second fixing frame 4, but the spherical fixing seat 1 is not completely locked, the angle of the nozzle mounting hole 2 can be fine-tuned by the adjusting handle 7, and the adjustment is more accurate and labor-saving. At the same time, the operator can also hold the spherical fixing seat 1 by the adjusting handle 7, so that the spherical fixing seat 1 remains motionless during the locking process of the locking member, thereby preventing the problem of the angle of the nozzle mounting hole 2 being offset when the locking member locks the first fixing frame 3 and the second fixing frame 4.

[0042] Optionally, in order to facilitate operation, the extending direction of the threaded hole is arranged to be inclined relative to the axis of the spherical fixing seat 1. Figure 1 As shown, the adjustment handle 7 is connected to the spherical fixing seat 1 in an inclined manner. Preferably, the angle between the extension direction of the threaded hole and the axis of the spherical fixing seat 1 is 40°.

[0043] Furthermore, the outer diameter of the spherical fixing seat 1 is 52 mm-60 mm, and the diameter of the circular hole 5 is 47 mm-55 mm. At the same time, it must be satisfied that the diameter of the circular hole 5 is smaller than the outer diameter of the spherical fixing seat 1 .

[0044] With this technical solution, the aperture of the circular hole 5 provides reliable support, ensuring that the spherical fixing seat 1 is firmly fixed at different angles; in addition, a larger angle adjustment range can be provided to better adapt to different processing requirements.

[0045] Optionally, in this embodiment, the outer diameter of the spherical fixing seat 1 is 55 mm, and the diameter of the circular hole 5 is 50 mm.

[0046] Furthermore, the locking member is a bolt 6, the first fixing frame 3 is provided with a first connecting hole 31, the second fixing frame 4 is provided with a second connecting hole 41, and the bolt passes through the first connecting hole 31 and the second connecting hole 41 corresponding to the position, so as to connect the first fixing frame 3 and the second fixing frame 4. When the bolt is tightened, the first fixing frame 3 and the second fixing frame 4 can provide a clamping force to the spherical fixing seat 1 to lock the orientation of the nozzle mounting hole 2. With this technical solution, the structure is simple and easy to operate. In addition, in addition to being able to lock the relative position between the first fixing frame 3 and the second fixing frame 4, the bolt 6 can also pass through the first connecting hole 31 and the second connecting hole 41 to fix the spherical fixing seat 1, the first fixing frame 3 and the second fixing frame 4 to the barrel wall of the feeding barrel.

[0047] Furthermore, the side facing each other of the first fixing frame 3 and the second fixing frame 4 is the inner side, and the side away from each other is the outer side; the edge of the circular hole 5 is provided with a limiting edge 8 folded toward the outside, and when the spherical fixing seat 1 is clamped between the two circular holes 5, the outer surface of the spherical fixing seat 1 fits with the inner surface of the limiting edge 8.

[0048] Specifically, the edges of the circular holes 5 of the first fixing frame 3 and the second fixing frame 4 are folded outward to form a limiting edge 8. The limiting edge 8 folded outward and the main bodies of the first fixing frame 3 and the second fixing frame 4 form a trumpet shape that is tightened outward, so that the outer surface of the spherical fixing seat 1 fits with the inner surface of the limiting edge 8, increasing the contact area between the fixing seat 1 and the first fixing frame 3 and the second fixing frame 4, thereby not only facilitating the insertion of the spherical fixing seat 1 into the circular hole 5, but also better clamping the spherical fixing seat 1. In addition, the limiting edge 8 can also play a role in limiting and shaping the fixing frame 1, preventing the fixing frame from being deformed due to long-term high temperature and high humidity.

[0049] Furthermore, the first fixing frame 3 and the second fixing frame 4 are in the shape of a triangular plate to match the shape of the barrel wall of the feeding barrel, thereby facilitating the installation and fixation of the nozzle fixing device.

[0050] Furthermore, the number of the first connection holes 31 and the number of the second connection holes 41 are both three, and the three first connection holes 31 and the three second connection holes 41 are respectively arranged at three corners of the first fixing frame 3 and the second fixing frame 4, and the first connection holes 31 and the second connection holes 41 are respectively evenly arranged around the circular hole 5.

[0051] By adopting this technical solution, the first fixing frame 3 and the second fixing frame 4 can fix the spherical fixing seat 1 more stably.

[0052] Furthermore, the edges of the first fixing frame 3 and the second fixing frame 4 are both provided with flanges 9 bent toward the outside, wherein the flange 9 on one side is provided with an arc-shaped notch 10 .

[0053] By adopting this technical solution, by providing the flange 9, it is convenient for the operator to hold the first fixing frame 3 and the second fixing frame 4 by hand when installing the first fixing frame 3 and the second fixing frame 4, so as to facilitate loading and unloading. In addition, a notch 10 is provided on the flange 9 to facilitate the adjustment of the angle of the spherical fixing seat 1 through the adjustment handle 7. When installing the spherical fixing seat 1, it is necessary to align the threaded hole on it with the notch 10, so that when the adjustment handle 7 is turned, the notch 10 can give way to the rod 71 to prevent the rod 71 from interfering with the flange 9, thereby facilitating the operator to use it.

[0054] Furthermore, the spherical fixing seat 1 is made of nylon material.

[0055] This technical solution ensures the wear resistance and stability of the spherical fixing seat 1 during the adjustment process, thereby extending the service life of the spherical fixing seat 1.

[0056] The barrel wall of the feeder is provided with an installation opening for installing the nozzle fixing device. When installing the nozzle fixing device provided in the present application, first fix the first fixing frame 3 to the inner barrel wall of the feeder barrel, align the circular hole 5 on the first fixing frame 3 with the installation opening, and then install the spherical fixing seat 1 through the installation opening and extend it into the circular hole 5 on the first fixing frame 3, and make the outer wall of the spherical fixing seat 1 fit with the inner surface of the limiting edge 8 of the first fixing frame 3, and then set the second fixing frame 4 on the outer side of the barrel wall, so that the spherical fixing seat 1 is clamped between the first fixing frame 3 and the second fixing frame 4, and then adjust the angle of the nozzle mounting hole 2, and make the threaded hole on the spherical fixing seat 1 face the notch 10. Afterwards, the relative position between the first fixing frame 3 and the second fixing frame 4 is locked by a locking member to clamp the spherical fixing seat 1. During the process of locking the first fixing frame 3 and the second fixing frame 4 by the locking member, the spherical fixing seat 1 may be offset. The adjusting handle 7 is threadedly connected to the spherical fixing seat 1 and the angle of the nozzle mounting hole 2 of the spherical fixing seat 1 is further adjusted to accurately control the angle of the nozzle mounting hole 2 and adjust and fix the injection angle of the nozzle 101 to the optimal state, thereby ensuring the atomization effect and improving the uniformity of the tobacco dressing inside the feeding barrel.

[0057] According to the nozzle fixing device provided by the utility model, the direction of the nozzle can be adjusted, so as to accurately adjust the spray angle of the nozzle, thereby improving the uneven dressing of tobacco leaves inside the feeding barrel.
