[0034] Please refer to Figure 1 , the utility model technical scheme, specifically a reconstituted tobacco leaf coating liquid conveying device with a clearing function is described, including: a coating liquid outlet, a coating liquid feeding pipeline 10, a backwashing clearing unit, and a coating unit;

[0035] Specifically, in this embodiment, the coating liquid feeding pipe 10 is inclined, so that the coating liquid with a large viscosity can be better transported under the auxiliary effect of gravity, and the coating liquid feeding pipe 10 is provided with the coating liquid outlet along the coating liquid conveying direction. More specifically, the coating liquid outlet is arranged on the side wall of the coating liquid feeding pipe 10 perpendicular to the coating liquid conveying direction;

[0036] And, if Figure 1 As shown, in this embodiment, the coating liquid outlet is arranged corresponding to the coating unit, and the coating unit and the coating liquid conveying direction are arranged parallel to each other, and the coating liquid outlet is used to convey the coating liquid to the coating unit;

[0037] In order to cope with the situation in the prior art that the coating liquid outlet in the coating liquid conveying device is blocked, the coating liquid feeding pipeline 10 is further provided with the recoil clearing unit, and the recoil clearing unit and the coating liquid outlet are arranged in sequence along the coating liquid conveying direction. More specifically, in the present embodiment, the recoil clearing unit is arranged above the coating liquid outlet. When the coating liquid outlet is blocked, the coating liquid feeding pipeline 10 can be closed by the recoil clearing unit to prevent the coating liquid from flowing in again, and at the same time, high-pressure fluid is provided to the coating liquid outlet to eliminate the blockage of the coating liquid outlet and ensure the conveying of the coating liquid.

[0038] Further, such as Figure 1 As shown, in this embodiment, the specific structure of the recoil clearing unit includes: a clearing port and a valve;

[0039] like Figure 1 As shown, in this embodiment, the specific arrangement structure of the recoil clearing unit is that along the coating liquid conveying direction, the valve, the clearing port, and the coating liquid outlet are sequentially arranged on the coating liquid feeding pipeline 10;

[0040] Through the sequential structure arranged in this way, the normal flow of the clearing port and the specific function of clearing the blockage can be achieved through the opening and closing of the valve. The specific implementation principle is as follows:

[0041] When the valve is open, the coating liquid feeding pipe 10 is connected to the coating liquid outlet. At this time, the coating liquid can be smoothly transported from the coating liquid feeding pipe 10 to the coating liquid outlet without entering the clearing port. At this time, the coating liquid outlet is in a normal working state;

[0042] When the valve is in the closed state, the clearing port is connected to the coating liquid outlet. When the coating liquid outlet is in the blocked state, the valve needs to be switched to the closed state. At this time, the coating liquid is blocked by the valve in the coating liquid feeding pipe 10 to prevent it from flowing into the coating liquid outlet. At this time, the clearing port is connected to the coating liquid outlet. High-pressure fluid is delivered to the coating liquid outlet through the clearing port, which can effectively deal with the blockage of the coating liquid outlet.

[0043] Preferably, in order to more evenly deliver the coating liquid to the coating unit, a plurality of coating liquid outlets are usually provided on the coating liquid feeding pipeline 10, and Figure 1 As shown, specifically in this example, the number of coating liquid outlets is 3, including: a first coating liquid outlet 1, a second coating liquid outlet 2, and a third coating liquid outlet 3; similarly, each of the coating liquid outlets will be provided with a corresponding recoil clearing unit for recoil clearing when each coating liquid outlet is blocked, specifically: a first valve 4, a second valve 5, a third valve 6, a first clearing port 7, a second clearing port 8, and a third clearing port 9.

[0044] Furthermore, in order to improve the coating quality of the tobacco leaves, a plurality of coating liquid outlets are evenly arranged on the coating liquid feeding pipe 10 along the coating liquid conveying direction to ensure that the coating liquid is arranged in a concentrated or dispersed manner.

[0045] Preferably, due to the provision of several coating liquid outlets, each of the coating liquid outlets may be blocked individually. Therefore, in this embodiment, the valve and the clearing port in each recoil clearing unit can be controlled individually to better deal with the blockage situation of each coating liquid outlet.

[0046] Better yet, in order to achieve the best recoil clearing effect, in the present embodiment, the clearing port and the coating liquid outlet are arranged on both sides of the coating liquid feeding pipe 10, and through such a layout and structural design, the high-pressure fluid provided in the clearing port can be better transported to the coating liquid outlet, so as to complete the recoil clearing operation more efficiently.

[0047] Preferably, in the present example, the high-pressure fluid provided by the clearing port to the coating liquid outlet is compressed air for backflushing. Compared with using high-pressure liquid, using compressed air as the high-pressure fluid can better accomplish the backflushing and clearing of the coating liquid outlet, thereby avoiding changes in the relevant process concentration of the coating liquid due to the use of liquid, thereby affecting product quality.

[0048] More preferably, the clearing port is also connected to an air compressor to efficiently provide compressed air to the coating liquid outlet.

[0049] As a preferred example, Figure 1 As shown, in this embodiment, the specific structure of the coating unit includes: an upper coating roller 11 and a lower coating roller 12;

[0050] The layout structure is as follows: the coating upper roller 11 and the coating lower roller 12 are arranged parallel to each other and parallel to the coating liquid conveying direction. Compared with the coating lower roller 12, the coating upper roller 11 is arranged closer to the coating liquid outlet;

[0051] Therefore, the coating liquid conveying process in this embodiment is: after being conveyed through the coating liquid feeding pipe 10, the coating liquid outlet conveys the coating liquid to the coating upper roller 11, and then is transferred to the coating lower roller 12 through the roller design to complete the conveying of the coating liquid.

[0052] Preferably, in order to facilitate the operator to observe the blockage of the coating liquid outlet more clearly and intuitively, in the present embodiment, the coating liquid feeding pipe 10 is made of transparent glass material. When the coating liquid outlet is blocked, the coating liquid feeding pipe 10 made of transparent material can be directly observed visually for timely processing.

[0053] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
