AI Technical Summary
The drop between the secondary tobacco stem outlet and the screening spring vibrating trough of the existing tobacco stem lubricating machine causes tobacco stem leakage, especially during vibration, some tobacco stems bounce to the ground, causing leakage.
A transition trough and a flexible curtain are installed between the secondary tobacco curing outlet of the tobacco curing machine and the vibrating trough. The transition trough includes an extension plate with side baffles. The flexible curtain forms a bend between the moisture exhaust hood and the vibrating trough. A barrier net is installed on the flexible curtain to prevent tobacco stems from falling in. The flexible curtain is made of waterproof material to maintain stability.
By eliminating the drop and buffering the slippage of tobacco stems, leakage is reduced, ensuring that no tobacco stems leak out under normal operating conditions of the vibrating trough, while effectively collecting condensate and maintaining humidity control.

[0023] like Figures 1-3 As shown, this utility model discloses a leak-proof device for tobacco stems at the secondary stem-moistening outlet of a stem-moistening machine, comprising:
[0024] The transition trough 1 is set between the secondary lubrication outlet and the vibrating trough 3. The transition trough 1 includes an extension plate 11 with a side baffle 12. The extension plate 11 is inclined. One end of the extension plate 11 is rotatably connected to the bottom of the secondary lubrication outlet, and the other end of the extension plate 11 is placed on the inlet end of the vibrating trough 3.
[0025] The flexible curtain 2, positioned between the desiccant 4 and the vibrating trough 3, has a length greater than the distance between them, creating a bend 21. The flexible curtain 2 is fixedly connected to the desiccant 4 and the vibrating trough 3 using adhesives or other common methods. The bend 21 serves two purposes: firstly, it prevents the vibration of the vibrating trough 3 from affecting the stability of the desiccant 4; secondly, it helps to collect condensate from the desiccant 4.
[0026] It should be understood that this utility model is based on the modification of existing stem lubrication machines, vibrating troughs, and dehumidification hoods, and the structure and principle of the aforementioned existing equipment will not be described in detail.
[0027] In the embodiment, the flexible fabric 2 is provided with a blocking net 22 for preventing the tobacco stems from falling into the bending part 21, the aperture of the blocking net 22 is smaller than the diameter of the tobacco stems, the flexible fabric 2 is waterproof fabric, the flexible fabric 2 is symmetrically arranged on both sides of the vibration groove 3, the bending part 21 is located outside the vibration groove 3, and the bottom area of the bending part 21 is provided with at least two layers of flexible fabric material. The lowest point of the bending part 21 is provided with a water collecting outlet. The waterproof fabric and the blocking net 22 can be obtained through commercial channels, the waterproof fabric is selected from common waterproof tarpaulins such as PCV tarpaulin and PE tarpaulin, the bottom area of the bending part 21 is stitched with multiple layers of tarpaulin to increase the self weight, and the blocking net 22 can be selected from nylon mesh and glass fiber mesh and is fixed on the waterproof fabric in a manner of gluing or sewing.
[0028] In the embodiment, in order to ensure the normal operation of the transition groove body 1, the width of the transition groove body 1 is greater than the width of the secondary tobacco stem moistening outlet and smaller than the width of the vibration groove 3; in order to reduce the noise generated when the transition groove body jumps with the vibration groove and to protect the extension plate and the vibration groove structure, the elastic pad 31 is arranged on the area of the inlet end of the vibration groove 3 in contact with the extension plate 11, and the elastic pad 31 can be rubber pad and is fixed on the vibration groove 3 through gluing.
[0029] The working principle of the utility model is as follows:
[0030] When the tobacco stem leakage prevention device is used, the tobacco stems are sent into the screening spring vibration groove through the transition groove body 1 from the secondary tobacco stem moistening outlet of the tobacco stem moistening machine after being moistened for the second time, and are conveyed to the subsequent process with the vibration of the vibration groove 3.
[0031] In this process, the transition groove body 1 jumps with the vibration of the vibration groove 3, and the tobacco stems do not stay in the extension plate 11 but slide into the vibration groove 3, and due to the arrangement of the transition groove body 1, the difference between the secondary tobacco stem moistening outlet of the tobacco stem moistening machine and the inlet end of the corresponding vibration groove 3 is eliminated, so that the tobacco stems can be buffered and slid to the vibration groove 3 through the transition groove body 1, thereby avoiding the tobacco stems from directly falling into the vibration groove 3 and reducing the probability of the tobacco stems jumping to the ground with the vibration of the vibration groove 3 to cause material leakage.
[0032] Meanwhile, the flexible fabric 2 is arranged in the gap between the inlet end of the vibration groove and the corresponding moisture discharge cover, so that the possibility of material leakage caused by the tobacco stems jumping out with the vibration of the vibration groove is finally eliminated.
[0033] In addition, the arrangement of the flexible fabric 2 closes the inlet end area of the vibration groove to a certain extent, which is beneficial to the pumping of the moisture discharge cover and makes the humidity more controllable.
[0034] The above examples are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
