[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figures 1 to 6 As shown, this invention discloses a humidification device for filter rod forming, used to humidify the paper tape 1 before winding and forming to reduce its hardness, comprising:

[0046] Humidification section 2, which allows paper tape 1 to pass through and humidify paper tape 1.

[0047] Liquid supply unit 3 is connected to humidification unit 2 and is used to atomize humidification liquid to form water vapor.

[0048] The humidification unit 2 includes a humidification chamber, which is equipped with a steam distribution plate 21, a sealing part 22, and a negative pressure part.

[0049] The steam separator 21 is used to divide the internal space of the humidification chamber and guide the direction of water vapor circulation inside the humidification chamber.

[0050] The sealing part 22 is provided with a passage gap corresponding to the paper tape 1. The sealing part 22 is used to prevent water vapor from overflowing from the inside of the humidification chamber.

[0051] The negative pressure section is used to drive the circulation of water vapor inside the humidification chamber.

[0052] In use, the humidification device is set at least one station before the winding and forming step. Then, the paper tape 1 is driven to pass through the humidification section 2 at a uniform speed. The atomized water vapor inside the humidification section 2 adheres to and integrates into the paper tape 1, wetting the paper tape 1 to reduce the hardness of the paper tape 1, so as to facilitate the subsequent winding and forming of the paper tape 1.

[0053] Specifically, in this application, there are two sets of steam distribution plates 21. The two sets of steam distribution plates 21 are arranged on both sides of the paper tape 1 along the traveling direction of the paper tape 1. The opposite sides of the two sets of steam distribution plates 21 form an impregnation section 01 for the paper tape 1 to pass through.

[0054] The steam separator plate 21 has a connecting hole 211 corresponding to the liquid supply section 3.

[0055] A flow gap is provided between the steam separator plate 21 and the sealing part 22 to allow water vapor to flow.

[0056] In the above structure, such as Figure 5 As shown, the steam distribution plate 21 is used to separate the internal space of the humidification chamber in order to plan the movement path of water vapor inside the humidification chamber. Specifically, the two steam distribution plates 21 on opposite sides form a wetting section 01 for the paper tape 1 to pass through, while the two steam distribution plates 21 on opposite sides form a water vapor return section. The wetting section 01 is connected to the liquid supply section 3 through the connecting hole 211. The wetting section 01 is filled with a large amount of water vapor, which can adhere to the surface of the paper tape 1 when the paper tape 1 passes through, thereby achieving the purpose of wetting the paper tape 1.

[0057] In this application, there are two sets of liquid supply sections 3, which are distributed on both sides of the humidification section 2.

[0058] The liquid supply unit 3 is equipped with a water storage tank and an atomizing device.

[0059] A sealing conduit 31 corresponding to the connecting hole 211 is provided at one end of the liquid supply section 3 near the humidification section 2.

[0060] The atomizing device in the liquid supply section 3 can draw water from the water tank and atomize it into small water droplets, which are then injected into the humidification section 2. The water vapor will pass through the connecting hole 211 into the wetting section 01 and quickly fill the wetting section 01. Then it will act on the paper tape 1. Some of the water droplets attached to the paper tape 1 will rise with the inertia generated by the movement direction of the paper tape 1, while the other part of the water droplets will fall under the action of gravity.

[0061] In this application, the liquid supply section 3 is equipped with heating equipment, a water storage tank and an atomizing device, which improves the wetting effect of the paper tape 1 by heating the water vapor.

[0062] It should be further noted that the unit also includes a frame assembly 5; the humidification unit 2 and the liquid supply unit 3 are mounted on the frame assembly 5.

[0063] The frame assembly 5 is also equipped with a guide wheel assembly 4, which is used to pull the paper tape 1 from bottom to top through the humidification section 2. It is easy to imagine that the frame assembly 5 is equipped with a drive unit that drives the guide wheel assembly 4.

[0064] In this application, there are two sets of sealing parts 22, which are distributed vertically. The width of the passage gap on the two sets of sealing parts 22 is the same as the thickness of the paper tape 1.

[0065] It needs to be specifically explained that, such as Figure 5 As shown, the top sealing part 22 is concave and the bottom sealing part 22 is convex. The sealing part 22 is positioned in the center of the sealing part 22 through the gap. The sealing part 22 is the same thickness as the paper tape 1 to prevent water droplets from flowing out, thereby achieving the effect of uniform wetting of the paper tape.

[0066] Specifically, during use, some of the water droplets attached to the paper tape 1 will rise due to the inertia generated by the movement direction of the paper tape 1, and these water droplets will accumulate in the depression of the top sealing part 22 as the paper tape 1 continues to run, thereby continuously wetting the paper tape 1 that passes through.

[0067] In this application, both ends of the two steam distribution plates 21 are provided with inclined surfaces that are inclined toward the sealing part 22.

[0068] With the above structural arrangement, the water vapor inside the wetting part 01 can be concentrated and moved toward the paper strip 1 by the influence of the inclined surface during the process of the suction of the negative pressure part, and act on the paper strip 1, thereby improving the adhesion efficiency of water vapor, accelerating the wetting process and improving the wetting effect.

[0069] It should be noted that the negative pressure section includes a first negative pressure zone 23 and a second negative pressure zone 24.

[0070] The first negative pressure zone 23 and the second negative pressure zone 24 are distributed vertically within the humidification section 2, but are not located within the immersion section 01.

[0071] The first negative pressure zone 23 and the second negative pressure zone 24 include air vents opened in the humidification chamber, a negative pressure pipe communicating with the air vents, and a negative pressure power unit connected to the negative pressure pipe.

[0072] The negative pressure power unit is connected to the liquid supply unit 3. The negative pressure power unit is used to drive the water vapor circulation inside the humidification unit 2 and the liquid supply unit 3. Specifically, the negative pressure power unit is a vacuum pump. Its output end is connected to the water storage tank, and its input end is connected to the humidification unit 2 through the negative pressure pipe. It is used to draw water vapor from the humidification unit 2 and re-enter the humidification unit 2 through the liquid supply unit 3 for circulation. It should be added that the top of the water storage tank is connected to the humidification unit 2 through the sealed conduit 31. The output end of the atomizing device is set in the sealed conduit 31. The atomizing device is used to draw water from the water storage tank and atomize it into water droplets. Then, the water mist is sprayed into the connecting hole 211 through the sealed conduit 31.

[0073] In this application, the humidification unit 2 is also provided with a drain pipe 25, which is located at the bottom of the humidification chamber and is connected to the liquid supply unit 3.

[0074] With the above structural arrangement, when water vapor enters the wetting section through the connecting hole 211 and acts on the paper tape 1, some of the water vapor will rise due to the inertia generated by the movement direction of the paper tape 1, while the other part of the water vapor will fall under the action of gravity.

[0075] To prevent rising water vapor from accumulating at the sealing part 22, a first negative pressure zone 23 is provided. The first negative pressure zone 23 can be used to draw up the rising water vapor and guide it into the liquid supply part 3, while excess water vapor will drip onto the steam distribution plate 21 and slide down to the bottom of the humidification part 2 with the steam distribution plate 21.

[0076] The falling water vapor accumulates in the lower space of the humidification section 2 under the influence of gravity. At this time, under the negative pressure of the second negative pressure zone 24, the water vapor can be adsorbed and flow out along the drain pipe 25 into the liquid supply section 3.

[0077] In the above mechanism, the negative pressure section can be used to drive the airflow inside the wetting section 01 to circulate, and the water droplets generated by the liquid supply section 3 can continuously act on the paper tape 1 to wet the paper tape 1 as the airflow circulates, ensuring that the humidity inside the wetting section 01 is at the same standard state.

[0078] Finally, it should be noted that the humidification chamber includes two sets of sealed shells 26, which are arranged opposite to each other, and the two sets of sealed shells 26 have missing parts on opposite sides. The missing parts of the two sets of sealed shells 26 form the humidification chamber, and there is an installation gap between the two sets of sealed shells 26 that corresponds to the passage gap of the sealing part 22.

[0079] With the above-mentioned installation gap setting, the paper tape 1 can be easily installed into the sealing part 22 and guide wheel assembly 4 inside the humidification part 2 during use.

[0080] In summary, this application allows the paper strip 1 to be moistened and softened before processing by passing it through the humidification section 2. This effectively avoids the situation where the paper strip 1 is too hard and will bend, deform, or even break during the winding process. In order to ensure that the paper strip 1 is moistened and softened evenly, the humidification section 2 is provided with a steam distribution plate 21 and a negative pressure section to drive the water vapor to circulate in the humidification section 2 and act evenly on the paper strip 1, avoiding the situation where water vapor accumulates in one place. At the same time, it can also prevent water vapor from overflowing and affecting the working environment.

[0081] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0082] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
