Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing, and more particularly to a tobacco humidifier capable of automatically adjusting water spraying. Background Art

[0002] Tobacco shred processing is an important link in the cigarette processing process and an important guarantee for achieving cigarette product design requirements and improving product processing quality. It mainly includes slicing, loosening and moisture recovery, leaf storage, leaf moistening and adding materials, shredding, leaf shred heating and humidification, leaf shred drying, flavoring and other processing steps. The tobacco leaves after modulation and re-roasting are made into shredded tobacco, which is expanded through the tobacco expansion process to become expanded shredded tobacco. Tobacco expansion is divided into leaf shred expansion and stem shred expansion. Tobacco expansion can also be divided into full formula expansion and partial expansion. Full formula expansion can also be called online expansion. All the shredded tobacco used in cigarettes are heated and humidified, and then immediately sent to the tobacco drying machine for rapid drying. The humidification method in the prior art is mostly to feed the expanded tobacco into a sealed chamber, and then fill the sealed chamber with moisture while turning the expanded tobacco. For example, patent authorization announcement No. CN216601625U discloses a pre-humidification device for tobacco processing in a cigarette factory. Although this method can humidify the tobacco evenly by turning it, the position where the moisture is introduced is fixed. In order to ensure uniform humidification of the tobacco, the tobacco needs to be fully turned and stirred. However, the tobacco is easily broken during the turning and stirring process, which not only affects the subsequent processing, but also affects the quality of the finished cigarette.

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0030] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0031] Example 1:

[0032] according to Figures 1 to 4 As shown, the utility model provides a tobacco humidifier with automatic water spraying adjustment, comprising a tobacco storage tank 1, a stand 2, a movable stand 4 and a water spraying humidifying mechanism 5;

[0033] The tobacco storage tank 1 includes a tank body 11, and the center of the tank body 11 is surrounded by a ring baffle 12 to form a central hollow groove; the stand 2 is located on both sides of the tank body 11, and the movable platform 4 is located directly above the tank body 11, and the two ends of the movable platform 4 are connected to the stand 2 through a lifting mechanism 3.

[0034] The water spraying and humidifying mechanism 5 includes a hollow shaft 51, an atomizing nozzle 54 and a water pump 57; the hollow shaft 51 is rotatably connected to the movable frame 4, and the bottom of the hollow shaft 51 is closed, and the top is connected to a water pipe 55 through a rotary joint 56, the water pump 57 is connected to the water pipe 55, and the atomizing nozzle 54 is connected to the hollow shaft 51 to spray and humidify the tank body 11.

[0035] Furthermore, the lifting mechanism 3 includes a motor 31 installed in one side frame 2. A screw 32 is vertically fixed to the output end of the motor 31. A screw sleeve 33 is threadedly mounted on the screw 32. A guide rod 34 is vertically provided in the other side frame 2. A guide sleeve 35 is slidably mounted on the guide rod 34. The screw sleeve 33 and the guide sleeve 35 are connected to the movable platform 4 via a connecting plate 36. The lifting mechanism 3 can drive the movable platform 4 to move up and down above the tobacco storage tank 1.

[0036] Furthermore, if Figure 4 As shown, a water shutoff assembly 52 is provided below the hollow shaft 51. The water shutoff assembly 52 includes a water container 521 fixedly mounted on the lower end of the hollow shaft 51. A spherical stopper 522 is connected to the water container 521 via an elastic member. The atomizing nozzle 54 is connected to the water container 521 at the lower end of the spherical stopper 522. The elastic member is a spring 526 vertically connected between the spherical stopper 522 and the inner wall of the water container 521. When in a free state, the spring 526 pushes the spherical stopper 522 to the position of the water outlet of the water container 521, thereby blocking the water outlet of the water container 521 through the spherical stopper 522.

[0037] A vertical rod 524 that passes through the water container 521 is provided at the bottom of the spherical stopper 522, and a push block 525 is provided at the bottom of the vertical rod 524. The push block 525 abuts against the bottom of the central hollow groove. When the movable platform 4 moves downward as a whole, the spherical stopper 522 moves upward under the action of the push block 525, and the hollow shaft 51 is connected to the atomizing nozzle 54; when the movable platform 4 moves upward as a whole, the spherical stopper 522 moves downward under the action of the elastic member, and the hollow shaft 51 is disconnected from the atomizing nozzle 54.

[0038] In this embodiment, when the lifting mechanism 3 drives the movable frame 4 to move downward, the vertical rod 524 is inserted into the central slot and moves downward. At the same time, the atomizing nozzle 54 is inserted into the tobacco in the tobacco storage tank 1. When the push block 525 abuts the bottom of the central slot, the spherical plug 522 overcomes the elastic force of the spring 526 and moves upward under the thrust of the vertical rod 524, opening the water outlet of the water container 521. The water pump 57 draws the water into the water container 521 through the water pipe 55, which can flow smoothly into the diversion pipe 53 and be directly atomized and sprayed into the tobacco storage tank 1 from each atomizing nozzle 54 to spray water and humidify the tobacco. When the lifting mechanism 3 drives the atomizing nozzle 54 to move out of the tobacco, the spherical plug 522 is pushed downward under the elastic force of the spring 526, blocking the water outlet of the water container 521, and the water spraying work of the atomizing nozzle 54 can be stopped.

[0039] Furthermore, at least two diversion pipes 53 are provided on the water container 521 at the lower end of the spherical stopper 522 , and the atomizing nozzles 54 are respectively connected to the corresponding diversion pipes 53 .

[0040] The atomizing nozzle 54 extends vertically into the tank body 11, and a plurality of atomizing nozzle holes are evenly arranged on the atomizing nozzle 54. In this embodiment, the multiple diverter pipes 53 and the atomizing nozzle 54 ensure that the tobacco in the tank body 11 is evenly humidified.

[0041] Furthermore, the diverter pipes 53 are arranged in an annular array on the side wall of the water container 521 with the axis of the water container 521 as the center; the hollow shaft 51, the water container 521, the vertical rod 524 and the annular baffle 12 are located on the same central axis.

[0042] Furthermore, a sealing sleeve 523 is provided between the upper end of the vertical rod 524 and the water container 521. The sealing sleeve 523 seals the gap between the vertical rod 524 and the water container 521 to prevent water from flowing along the vertical rod 524 into the central empty groove and being difficult to clean.

[0043] Furthermore, if Figure 3 As shown, the present invention also includes a rotating mechanism 6, which includes a groove wheel 61 fixedly mounted on the hollow shaft 51, and a second motor 62 is provided on the movable frame 4. The output end of the second motor 62 is fixedly mounted with a dial 63 matching the groove wheel 61, and the dial 63 is provided with a dial post 64, which cooperates with the dial groove in the groove wheel 61 to drive the groove wheel 61 and the hollow shaft 51 to rotate.

[0044] Motor 2 62 is a stepping motor. Motor 2 62 can rotate one circle when it receives a pulse signal. When the lifting mechanism 3 drives the water spraying and humidifying mechanism 5 to move out of the tobacco storage tank 1, motor 2 62 operates. Under the action of the groove wheel 61 mechanism formed by the groove wheel 61 and the dial 63, the water spraying and humidifying mechanism 5 can be driven to rotate a certain angle. Then the lifting mechanism 3 drives the water spraying and humidifying mechanism 5 again to extend into the tobacco storage tank 1 to spray water and humidify the tobacco, thereby realizing automatic replacement of the water spraying position, and then humidifying the tobacco at different positions. Through the continuous cooperation of the lifting mechanism 3 and the rotating mechanism 6, the tobacco at different positions in the tobacco storage tank 1 can be humidified, and uniform humidification of the tobacco can be achieved. Moreover, the atomizing nozzle 54 moves straight up and down in the tobacco storage tank 1 without flipping the tobacco to cause the internal tobacco to be broken.

[0045] During specific use, the utility model is a tobacco humidifier with automatic adjustment of water spraying. When humidifying the tobacco in the tobacco storage tank 1, the motor 31 is operated first, driving the screw 32 to rotate, and under the cooperation of the screw 32 and the screw sleeve 33 and the guiding action of the guide rod 34 and the guide sleeve 35, the movable frame 4 and the water spraying humidifying mechanism 5 are driven to move downward, so that the atomizing nozzle 54 is inserted into the tobacco in the tobacco storage tank 1, and at the same time, the water pump 57 continuously pumps water into the water container 521 through the water pipe 55. When the push block 525 abuts against the bottom of the central hollow groove, the vertical rod 524 pushes the spherical stopper 522 to move upward, opening the water outlet of the water container 521, and the water in the water container 521 flows into the diversion pipe 53 and is directly atomized from each atomizing nozzle 54. Sprinkle it in the tobacco and spray water to humidify the tobacco. At this time, the spring 526 is in a compressed state. After spraying water for a certain period of time, the motor 1 31 reverses and drives the movable frame 4 to move upward, so that the atomizing nozzle 54 is removed from the tobacco. At the same time, the spherical stopper 522 is pushed downward under the elastic force of the spring 526 to block the water outlet of the water container 521. Then the motor 2 62 operates to drive the dial 63 to rotate, and the dial column 64 and the groove wheel 61 on the dial 63 cooperate to drive the water spraying and humidifying mechanism 5 to rotate a certain angle. Then the lifting mechanism 3 operates again to drive the atomizing nozzle 54 to extend into the tobacco storage tank 1 for water spraying and humidification. Repeat the above steps to continuously spray water and humidify the tobacco at different positions in the tobacco storage tank 1 to achieve uniform humidification of the tobacco.

[0046] Example 2:

[0047] Based on the first embodiment, Figure 2As shown, a humidity sensor 13 is installed in the tobacco storage tank 1, and the humidity sensor 13 is electrically connected to the water pump 57. The humidity sensor 13 can detect the humidity of the tobacco in the tobacco storage tank 1 in real time. When the humidity is too low, it can send a signal to the outside world and the water pump 57. The staff starts the tobacco humidifier, and the water pump 57 operates to pump water to humidify the inside of the tobacco storage tank 1. When the humidity reaches the standard value, the humidity sensor 13 sends a signal to the water pump 57 to control the water pump 57 to stop pumping water immediately. The water spraying humidification mechanism 5 can no longer spray water mist to prevent excessive humidification of the tobacco due to untimely shutdown.
