Description

Technical Field

[0002] In the tobacco processing process, the air atomizing nozzle 500 is a key component in the process of flavoring and adding materials to tobacco thread. The air atomizing nozzle 500 atomizes flavors and fragrances through compressed air and evenly sprays the atomized flavors and fragrances on the tobacco material at a certain spatial angle. Figure 1 As shown, the drum 700 rotates in a clockwise direction, and the tobacco in the drum 700 falls down as the drum 700 moves to the highest point on the left side, and the air atomizing nozzle 500 installed on the feed panel 600 atomizes and sprays the tobacco in the drum 700. The air atomizing nozzle 500 can swing with the installation point of the feed panel 600 as the center of the circle, and the air atomizing nozzle 500 is based on the plane formed by the X-axis and Z-axis where the feed panel 600 is located, and the spray angle of the atomizing nozzle 500 is adjusted in two directions along the X-axis direction and the Z-axis direction. According to the process requirements, the spray angle of the air atomizing nozzle 500 on the feed panel 600 is nine o'clock, which has a better effect on the atomization spray of tobacco, so as to fully ensure that the spices are evenly sprayed on the tobacco material. Therefore, in order to ensure that the tobacco fully absorbs the spices in the drum 700, the spray angle of the air atomizing nozzle 500 needs to be strictly controlled. When the tobacco shreds are unevenly sprayed with flavors, or after the air atomizing nozzle 500 is maintained and replaced, it is necessary to readjust the spray angle of the air atomizing nozzle 500. However, the adjustment is made based on the experience of the staff, and repeated adjustments often occur during the process, which not only increases the workload of the staff, but also affects the entire production rhythm due to the low efficiency of the adjustment work.

[0003] Therefore, how to improve the adjustment efficiency of the air atomizing nozzle while achieving precise adjustment of the spray angle is a technical problem that technical personnel in this field currently need to solve. Summary of the invention

[0043] Another object of the present invention is to provide a fragrance adding machine having the above-mentioned atomizing nozzle angle positioning device.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] like Figure 2 As shown, an embodiment of the present invention discloses an atomizing nozzle angle positioning device, including a nozzle support module 100, a first adjustment module 200 and a second adjustment module 300. Among them, the atomizing nozzle 500 is fixed on the nozzle support module 100, and is swingably mounted on the feed panel 600 through the nozzle support module 100. The first adjustment module 200 can push the nozzle support module 100 to swing along the first direction, and control the angle value of the nozzle support module 100 swinging along the first direction through the first scale part 210, and then accurately control the angle adjustment of the atomizing nozzle 500 along the first direction of the feed panel 600. The second adjustment module 300 pushes the nozzle support module 100 to swing along the second direction, and also sets a second scale part 310, and accurately controls the angle adjustment of the atomizing nozzle 500 along the second direction of the feed panel 600 through the second scale part 310, and the first direction and the second direction of the angle adjustment of the atomizing nozzle 500 are perpendicular to each other. In a specific embodiment, the first adjustment module 200 adjusts the spray angle of the atomizing nozzle 500 along the X-axis direction of the material panel 600, and the second adjustment module 300 adjusts the spray angle of the atomizing nozzle 500 along the Z-axis direction of the material panel 600.

[0046] The atomizing nozzle angle positioning device provided in this embodiment realizes rapid adjustment of the atomizing nozzle 500 along the first direction and the second direction through the first adjustment module 200 and the second adjustment module 300, while the first scale part 210 and the second scale part 310 realize quantification and precision of the angle adjustment process, so that the atomizing nozzle angle positioning device provided in this embodiment realizes efficient and precise angle adjustment of the atomizing nozzle 500.

[0047] like Figure 3As shown, the first adjustment module 200 includes a connecting rod 220, a support plate 230 and a first pointer 211, wherein the first end of the connecting rod 220 is hingedly mounted on the support plate 230, and the second end of the connecting rod 220 is fixed to the nozzle support module 100, so that the nozzle support module 100 is pushed to swing along the first direction by the rotation of the connecting rod 220 on the support plate 230. At the same time, a first rotation scale 212 for marking the rotation angle is engraved on the surface of the first end of the connecting rod 220, and the first pointer 211 fixed on the support plate 230 points to the scale line of the first rotation scale 212, and the angle adjustment value of the atomizing nozzle 500 along the first direction is indicated by the cooperation of the first pointer 211 and the first rotation scale 212, so that the cooperation of the first pointer 211 and the first rotation scale 212 forms the first scale part 210.

[0048] Meanwhile, the first adjustment module 200 further includes a connecting rod portion, and the connecting rod portion is provided with a first connecting rod 240 and a second connecting rod 250 . The first end of the first connecting rod 240 is hinged to the support plate 230, and the second end of the first connecting rod 240 is hinged to the first end of the second connecting rod 250. At the same time, the first end of the connecting rod 220 is provided with an arc groove 221, which extends along the rotation direction of the connecting rod 220, and the center of the arc groove 221 is located on the same side as the hinge point of the connecting rod 220 and the support plate 230. The second end of the second connecting rod 250 is hinged to the arc groove 221, so that a four-bar linkage mechanism is formed among the first connecting rod 240, the second connecting rod 250, the connecting rod 220 and the support plate 230. When a force is applied to the second connecting rod 250, the second end of the second connecting rod 250 cooperates with the arc groove 221 of the connecting rod 220, thereby pushing the connecting rod 220 to rotate along the first direction with the hinge point of the connecting rod 220 and the support plate 230 as the rotation center.

[0049] like Figure 2 and Figure 3As shown, the first adjustment module 200 includes a first rotating part 260, and the first rotating part 260 includes a mounting bracket 261, an adjustment rod 262, a first locking nut 263 and a second locking nut 264. The mounting bracket 261 is fixed on the support plate 230, and the mounting bracket 261 is provided with an adjustment rod mounting hole. The adjustment rod 262 passes through the adjustment rod mounting hole and is fixed to the first end of the second connecting rod 250. Then, the adjustment rod 262 can apply a force to the second connecting rod 250 to drive the operation of the connecting rod part. At the same time, after the angle of the atomizing nozzle 500 is adjusted along the first direction by pushing the adjusting rod 262, in order to improve the stability of the adjusted angle, a first locking nut 263 and a second locking nut 264 are provided, and the first locking nut 263 and the second locking nut 264 are both threadedly connected to the adjusting rod 262, and the first locking nut 263 and the second locking nut 264 are respectively located on both sides of the mounting bracket 261. After the adjustment is completed, the first locking nut 263 and the second locking nut 264 can be rotated to clamp the first locking nut 263 and the second locking nut 264 on the mounting bracket 261, so that the adjusting rod 262 is locked on the mounting bracket 261 and the adjusting rod 262 is fixed and limited. When the angle adjustment is required, the first locking nut 263 and the second locking nut 264 are rotated in the opposite direction to loosen the adjusting rod 262 from the mounting bracket 261.

[0050] like Figure 3 As shown, the mounting bracket 261 also has a first detection sensor 270, and the first detection sensor 270 performs real-time detection on the first locking nut 263 of the adjusting rod 262. Therefore, when the atomizing nozzle 500 deflects along the first direction, the relative position between the first detection sensor 270 fixed on the mounting bracket 261 and the first locking nut 263 on the adjusting rod 262 will change. When the first detection sensor 270 cannot detect the first locking nut 263, an alarm signal will be transmitted to promote the staff to make timely adjustments and corrections to ensure the normal operation of the tobacco atomization work. In a specific embodiment, the first locking nut 263 and the second locking nut 264 are both made of nylon material, so as to facilitate the first detection sensor 270 to detect the first locking nut 263 in real time.

[0051] like Figure 3 As shown, the second adjustment module 300 includes a rotating shaft 320, a base 330 and a second pointer 311. The rotating shaft 320 is rotatably mounted on the base 330, and the rotating shaft 320 is connected to the first adjustment module 200, and then the second adjustment module 300 drives the first adjustment module 200 to rotate along the second direction, thereby pushing the atomizing nozzle 500 installed on the first adjustment module 200 to adjust the angle along the second direction.

[0052] like Figure 4As shown, the second adjustment module 300 is also provided with a locking portion 340, and the locking portion 340 is provided with a first locking block 341 and a second locking block 342. The first locking block 341 and the second locking block 342 are respectively sleeved on the outside of the rotating shaft 320, and one of the first locking block 341 and the second locking block 342 is fixed on the base 330, and the first locking block 341 and the second locking block 342 are connected by an adjusting bolt. After the rotating shaft 320 adjusts the atomizing nozzle 500, the first locking block 341 and the second locking block 342 are tightened to each other by the adjusting bolt to clamp the rotating shaft 320 and limit the rotation of the rotating shaft 320 along its own axis. When it is necessary to adjust the angle of the atomizing nozzle 500 along the second direction, the adjusting bolt is rotated in the opposite direction to release the locking of the first locking block 341 and the second locking block 342 on the rotating shaft 320, so that the rotating shaft 320 can rotate. In a specific embodiment, the first locking block 341 is fixed to the base 330 by two M6 bolts, and the second locking block 342 is movable, and the second locking block 342 is connected to the first locking block 341 by two M4 bolts. When the rotating shaft 320 needs to be rotated, the two M4 bolts are loosened, and the rotating shaft 320 is rotated to a specified position. After the adjustment is completed, the two M4 bolts are tightened, that is, the rotating shaft 320 is locked and fixed by the first locking block 341 and the second locking block 342.

[0053] Similarly, if Figure 2 As shown, the base 330 is also provided with a second rotation scale 312 for marking the rotation angle of the rotation axis 320 , and the second pointer 311 cooperates with the second rotation scale 312 to achieve precise adjustment of the angle of the atomizing nozzle 500 along the second direction, forming a second scale portion 310 .

[0054] like Figure 5As shown, the atomizing nozzle angle positioning device provided in this embodiment also includes a slide rail portion 400. The slide rail portion 400 is provided with a first slide rail rod 410, a first slider 420, a second slide rail rod 430 and a second slider 440. The first slide rail rod 410 and the second slide rail rod 430 are both provided with a slide groove, and the first slider 420 and the second slider 440 are slidably mounted on the first slide rail rod 410 and the second slide rail rod 430 through the slide groove. The first slide rail rod 410 is fixed on the rotating shaft 320, and the first slide rail rod 410 extends along the axis direction of the rotating shaft 320, and the second slide rail rod 430 is mounted on the first slide rail rod 410 through the first slider 420, so that the second slide rail rod 430 can slide along the extension direction of the first slide rail rod 410, and the axis of the first slide rail rod 410 and the axis of the second slide rail rod 430 are perpendicular to each other. The support plate 230 of the first adjustment module 200 is slidably installed on the second slide rod 430 through the second slider 440, and then the rotating shaft 320 is connected to the first adjustment module 200 through the slide rail portion 400, thereby realizing the mutual connection between the second adjustment module 300 and the first adjustment module 200, and the relative positions of the first adjustment module 200 and the second adjustment module 300 can be adjusted in two directions along the axial direction of the first slide rod 410 and the axial direction of the second slide rod 430, and the relative position of the atomizing nozzle 500 on the feed panel 600 can be further adjusted.

[0055] like Figure 3 As shown, the base 330 is also provided with a second detection sensor 350. The second detection sensor 350 can detect the mounting bracket 261 of the first adjustment module 200 in real time. When the angle of the atomizing nozzle 500 changes along the second direction, that is, when the first adjustment module 200 rotates along the second direction, the relative position of the second detection sensor 350 on the base 330 and the mounting bracket 261 of the first adjustment module 200 changes. When the second detection sensor 350 cannot detect the mounting bracket 261, the second detection sensor 350 transmits an alarm signal to prompt the staff to adjust and correct the angle of the atomizing nozzle 500 along the second direction.

[0056] like Figure 2 As shown, the nozzle support module 100 includes a joint bearing 110 , and the atomizing nozzle 500 fixed on the nozzle support is installed on the feed panel 600 through the joint bearing 110 , thereby realizing the atomizing nozzle 500 to swing in different directions on the feed panel 600 .
