Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a sealing device for a tube and a leaf-beating and re-drying equipment. Background Technology

[0002] Leaf threshing and re-drying is a necessary processing step in transforming tobacco leaves from agricultural products into raw materials for cigarette production after harvesting, and it is a key link in the initial processing of tobacco leaves. Leaf threshing and re-drying equipment is a crucial piece of equipment in tobacco processing, mainly used for threshing, separating, and re-drying tobacco leaves to ensure that the quality of the tobacco leaves meets the requirements for subsequent processing and storage.

[0003] The leaf re-drying equipment mainly consists of a head cover (feed head cover and discharge head cover) and a cylinder. The head cover is a fixed part, and the cylinder is a rotating part. The cylinder and the head cover need to be sealed to prevent the leakage of media and materials inside the cylinder.

[0004] In existing technologies, the sealing between the cylinder and the hood is typically achieved by fixing a sealing device to the side plate of the hood, ensuring that the sealing device fits snugly against the cylinder. However, after a period of use, the sealing device wears down and can no longer fit snugly against the cylinder, creating gaps that allow material inside the cylinder to leak during operation.

[0005] Therefore, there is an urgent need for a sealing device for the cylinder and a leaf re-drying equipment to solve the above problems. Utility Model Content

[0006] The first objective of this invention is to provide a sealing device for a cylinder, in order to solve the problem in the prior art where there is a gap between the sealing device and the cylinder, and the material inside the cylinder is prone to leakage during operation.

[0007] The second objective of this invention is to provide a leaf-drying and re-drying device that solves the problem of easy material leakage.

[0013] Furthermore, the annular seal is a flexible sealing ring, which includes an annular fixing part and an annular abutting part connected to each other. The annular fixing part is located between the annular mounting assembly and the head cover side plate, and the annular seal is located between the annular abutting part and the cylinder.

[0014] Furthermore, the annular mounting assembly includes an annular pressure strip and a mounting member. The inner diameter of the annular pressure strip is larger than the outer diameter of the cylinder, and the mounting member is used to fix the annular pressure strip to the headgear side plate.

[0015] Furthermore, multiple mounting components are provided, and multiple mounting holes are provided on the annular pressure strip. The multiple mounting holes are provided one-to-one with the multiple mounting components and one-to-one with the multiple fixing holes on the head cover side plate.

[0016] Furthermore, the annular pressure strip includes multiple arc-shaped pressure strips, and multiple mounting holes are located on the multiple arc-shaped pressure strips.

[0017] Furthermore, at least two mounting holes are located at both ends of the arc-shaped pressure strip.

[0018] Furthermore, the sealing device for the cylinder also includes a limiting sleeve, one end of which is fixed to the annular mounting assembly, and the elastic fixing assembly passes through the limiting sleeve.

[0019] Furthermore, the elastic fixing component includes an elastic element and an arc-shaped fixing ring connected together.

[0020] Furthermore, one end of the arc-shaped retaining ring is detachably connected to one end of the elastic element, and the other end of the arc-shaped retaining ring is detachably connected to the other end of the elastic element.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] This invention provides a sealing device for a cylinder, which prevents material leakage inside the cylinder during operation.

[0037] For example, such as Figure 1 As shown, the sealing device for the cylinder includes an annular seal 1, an annular mounting assembly 2, and an elastic fixing assembly 3. The annular mounting assembly 2 is connected to the head cover side plate 100 and is used to install the annular seal 1 onto the head cover side plate 100. The elastic fixing assembly 3 is located on the side of the annular seal 1 away from the cylinder and is used to abut the annular seal 1 against the cylinder. With this configuration, even if the annular seal 1 wears during use, the elastic fixing assembly 3 ensures that the annular seal 1 remains in contact with the cylinder, preventing gaps between the annular seal 1 and the cylinder, and preventing material leakage inside the cylinder during operation.

[0038] It should be noted that the head cover side plate 100 is fixed to the head cover. The head cover and the cylinder are structures inside the leaf re-drying equipment, which are existing technologies and will not be described in detail in this embodiment.

[0039] Furthermore, the annular seal 1 can be a flexible sealing ring, which includes a connected annular fixing part (not shown in the figure) and an annular abutment part (not shown in the figure). The annular fixing part is located between the annular mounting assembly 2 and the head cover side plate 100, and the annular seal 1 is located between the annular abutment part and the cylinder. It is understood that the annular seal 1 is a flexible sealing ring, which allows it to abut against the outer surface of the cylinder under the fixing action of the elastic fixing assembly 3 after partial wear, thus improving the sealing effect of the annular seal 1. Moreover, the flexible sealing ring includes a connected annular fixing part and an annular abutment part, facilitating the fixing of the annular seal 1 and the abutment between the annular seal 1 and the outer surface of the cylinder, enabling a more stable seal between the cylinder and the head cover, preventing leakage of material inside the cylinder due to gaps between the annular seal 1 and the cylinder. In this embodiment, the flexible sealing ring is made of existing flexible materials, which is sufficient to meet actual usage requirements; this embodiment does not impose specific limitations.

[0040] Furthermore, the annular mounting assembly 2 includes an annular pressure strip 21 and a mounting component (not shown in the figure). The inner diameter of the annular pressure strip 21 is larger than the outer diameter of the cylinder, and the mounting component is used to fix the annular pressure strip 21 to the headgear side plate 100. It is understood that the inner diameter of the annular pressure strip 21 being larger than the outer diameter of the cylinder facilitates the installation of the annular pressure strip 21, and the mounting component used to fix the annular pressure strip 21 to the headgear side plate 100 ensures the stability of the annular pressure strip 21.

[0041] Furthermore, multiple mounting components are provided, and the annular pressure strip 21 has multiple mounting holes, each corresponding to a different mounting component and also corresponding to a different fixing hole (not shown in the figure) on the headgear side plate 100. It is understood that by providing multiple mounting components and corresponding mounting and fixing holes, the stability of the annular mounting assembly 2 can be further improved, thereby enhancing the fixing effect of the annular mounting assembly 2 on the annular seal 1. In this embodiment, the mounting component can be a bolt, and both the mounting and fixing holes can be threaded holes. The bolt and the threaded hole cooperate to achieve the installation of the annular pressure strip 21.

[0042] Furthermore, the annular pressure strip 21 includes multiple arc-shaped pressure strips (not shown in the figure), and multiple mounting holes are located on the multiple arc-shaped pressure strips. It can be understood that by setting the annular pressure strip 21 as multiple arc-shaped pressure strips, the arc-shaped pressure strips can be installed one by one during installation, which improves the convenience of installing the annular pressure strip 21 and the annular seal 1.

[0043] Furthermore, there are at least two mounting holes on the curved strip, located at both ends of the curved strip. It can be understood that when the end faces of adjacent curved strips meet, there are at least two mounting holes located at both ends of the curved strip, which can better fix the ends of the curved strip to ensure the flatness of the joint between adjacent curved strips after the two curved strips are installed on the headgear side panel 100.

[0044] Furthermore, the sealing device for the cylinder also includes a limiting sleeve 4, one end of which is fixed to the annular mounting assembly 2, and the elastic fixing assembly 3 passes through the limiting sleeve 4. It is understood that by setting the limiting sleeve 4, the elastic fixing assembly 3 is easily limited, improving its stability and preventing misalignment or detachment from the annular seal 1. In this embodiment, one end of the limiting sleeve 4 is fixed between the annular mounting assembly 2 and the head cover side plate 100, with the annular mounting assembly 2 and the head cover side plate 100 clamping and fixing one end of the limiting sleeve 4. Of course, in other embodiments, the limiting sleeve 4 can also be fixed using other fixing methods, as long as the actual needs are met; this embodiment does not specifically limit this.

[0045] Furthermore, the elastic fixing component 3 includes a connected elastic element (not shown in the figure) and an arc-shaped fixing ring (not shown in the figure). It is understood that by providing a connected elastic element and an arc-shaped fixing ring, the elastic element and the arc-shaped fixing ring can be coupled without requiring the elastic fixing component 3 to be a single, integrated elastic structure, thus facilitating installation. In this embodiment, the arc-shaped fixing ring has a certain width, increasing the contact area with the annular seal 1, thereby improving the fixing effect on the annular seal 1.

[0046] In this embodiment, to further facilitate the installation and replacement of the elastic element and the arc-shaped retaining ring, one end of the arc-shaped retaining ring is detachably connected to one end of the elastic element, and the other end of the arc-shaped retaining ring is detachably connected to the other end of the elastic element. This achieves the effect of facilitating the installation and replacement of the elastic element and the arc-shaped retaining ring. In this embodiment, the elastic element includes, but is not limited to, a spring. Connecting holes are provided at both ends of the arc-shaped retaining ring, and locking hooks are formed at both ends of the elastic element. The locking hooks cooperate with the connecting holes to achieve the connection between the elastic element and the arc-shaped retaining ring. Of course, in other embodiments, other structures can also be used for the detachable connection between the elastic element and the arc-shaped retaining ring. For example, locking buckles can be provided at both ends of the arc-shaped retaining ring, and locking rings can be provided at both ends of the elastic element. The locking buckles can connect with the locking rings. All structures for achieving the detachable connection between the elastic element and the arc-shaped retaining ring are existing technologies in the art, and this embodiment does not impose specific limitations; any structure that meets the usage requirements is acceptable.

[0047] This embodiment also provides a leaf-drying and re-drying device that solves the problem of easy material leakage.

[0048] For example, the leaf re-drying equipment includes a cylinder, a head cover, and a sealing device for the cylinder. By providing the sealing device for the cylinder, material is prevented from flowing out from the gap between the cylinder and the head cover.

[0049] In this embodiment, the sealing device for the cylinder is connected to the side plate 100 of the head cover to install the sealing device for the cylinder.

[0050] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
