Description

Technical Field

[0001] The utility model relates to the technical field of leaf threshing and re-drying, and more specifically, to a leaf threshing and re-drying hot air leaf moistening machine with a quick-detachable rake nail for the moistening cylinder. Background Art

[0002] During the leaf redrying process, MacTavish hot air moistening machines are commonly used to process tobacco agricultural products. Inside the hot air moistening machine, the tobacco leaves are continuously spiraled forward by the rotating moistening cylinder to the discharge outlet, completing the moistening process. Inside the cylinder, they are subjected to high-temperature, high-humidity steam to hydrate and heat the tobacco leaves. In tobacco redrying operations, the redrying process is crucial for controlling the intrinsic quality of the tobacco leaves and removing green and unpleasant odors. The hot air moistening cylinder is positioned at a 3-5° horizontal angle to the ground. Within the cylinder, the tobacco leaves are driven forward at a constant speed to the discharge outlet by gravity and the centrifugal force of the cylinder's rotation. Due to the physical properties of tobacco leaves, they are prone to tangling and clumping when subjected to stress. Therefore, the cylinder is often equipped with rakes to separate and loosen the tobacco leaves, ensuring uniform distribution. The hot air moistening cylinder primarily consists of the cylinder, the outer and inner walls, and the inner and outer rakes.

[0003] Tobacco leaves possess varying physical and chemical properties due to their origin and moisture content. This can lead to different behaviors during the high-temperature, high-humidity processing of tobacco leaves in the leaf conditioning drum, such as breakage, stickiness, clumping, and entanglement. The leaf threshing and redrying process often requires handling different incoming tobacco leaves in various states, such as "one-knife two-section," "two-knife three-section," "whole-leaf threshing," and "module-shaped tobacco." This necessitates targeted adjustments to the conditioning drum processing mode, which also involves changes in the arrangement, distribution, shape, and size of the rake spikes. Because the current design of the leaf conditioning drum rake spikes is all integrally welded to the inner wall of the drum, changing the rake spike arrangement often requires temporary cutting and grinding, significantly impacting the efficiency of the mode change and hindering the sustainability and stability of large-scale production models.

[0004] Therefore, there is an urgent need for a quick-detachable rake nail for the leaf-threshing and re-baking hot-air leaf-wetting machine. Utility Model Content

[0023] In the present disclosure, when a specific component is described as being located between a first component and a second component, there may or may not be an intervening component between the specific component and the first component or the second component. When a specific component is described as being connected to another component, the specific component may be directly connected to the other component without an intervening component, or may not be directly connected to the other component but have an intervening component.

[0024] All terms (including technical or scientific terms) used in this disclosure have the same meaning as those understood by one of ordinary skill in the art to which this disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in, for example, general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined herein.

[0025] 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.

[0026] As mentioned previously, leaf conditioning cylinders often require targeted changes in the layout and specifications of the rake spikes based on the state of incoming tobacco leaves. Some companies resort to temporary cutting and grinding to meet processing requirements. While this method can accommodate the processing needs of incoming tobacco leaves of varying specifications, frequent cutting and welding significantly impacts the life of the rake spikes. Furthermore, the low efficiency of cutting and grinding hinders continuous production. Furthermore, due to the ash coating inside the cylinder, cutting can easily lead to smoldering.

[0027] like Figures 1-4 As shown, the quick-release rake nail of the leaf threshing and re-drying hot air leaf moistening machine leaf moistening cylinder provided in this embodiment includes: a rake nail body 5, the rake nail body 5 is connected to the inner wall 1 of the hot air leaf moistening machine leaf moistening cylinder through a quick-release locking sleeve 2, and a twelve-card anti-retraction washer 3 is provided on the quick-release locking sleeve 2, and the twelve-card anti-retraction washer 3 is used to clamp the quick-release locking sleeve 2 and the rake nail body 5.

[0028] The rake nail body 5 is welded to the inner wall 1 of the leaf moistening cylinder of the hot air leaf moistening machine through a quick-release locking sleeve 2.

[0029] Furthermore, the outer peripheral surface of the rake nail body 5 has a rake nail force surface 6. In a specific implementation, the original rake nail can be disassembled and then modified, and the rake nail cross section can be polished and a bayonet groove can be cut to process the rake nail force surface 6.

[0030] At work, such as Figure 2 As shown, the quick-release locking sleeve 2 is welded to the inner wall 1 of the hot air leaf moistening machine's leaf moistening cylinder at the original rake nail welding position, which facilitates the timely dispersion of the blade impact force to the inner wall during operation. Then, the twelve-card retaining washer 3 is used to clamp the quick-release locking sleeve 2 and the rake nail body 5 up and down to ensure that the rake nail is firmly stressed after quick installation and timely transmits and disperses the force in the leaf moistening cylinder processing mode. When installation is required, simply screw the rake nail of the corresponding specification into the thread of the quick-release locking sleeve 2 and clamp the twelve-card retaining washer 3 to complete the reinforcement.

[0031] Furthermore, the length of the rake nail body 5 is 150mm-350mm. Preferably, the length of the rake nail body 5 is 200mm-300mm. More preferably, in one embodiment of the present invention, the length of the rake nail body 5 is 200mm or 300mm.

[0032] Furthermore, if Figure 3 and Figure 4 As shown, the shape of the rake nail body 5 is a "I" shape or an "L" shape. It should be noted that the length and shape of the rake nail body 5 are not specifically limited in the present invention.

[0033] Furthermore, in one embodiment of the present invention, four types of rake nails with different functions are designed according to the changes in the physical and chemical properties of tobacco leaves of different specifications after processing in the leaf moistening cylinder. Specifically, the specifications of the rake nail body 5 include: an "I"-shaped rake nail with a length of 200mm, an "L"-shaped rake nail with a length of 200mm, an "I"-shaped rake nail with a length of 300mm, and an "L"-shaped rake nail with a length of 300mm. During use, for tobacco leaves with "one knife and two sections" specifications, combined with the tobacco leaf winding characteristics, a rake nail array mode with a combination of 200mm "I" type and 200mm "L" type layers is often used for processing; for tobacco leaves with "two knife and three sections" specifications, combined with the tobacco leaf winding characteristics, a rake nail array mode with a combination of 300mm "I" type and 300mm "L" type layers is often used for processing; for tobacco leaves with "full leaf beating" specifications, combined with the tobacco leaf winding characteristics, a rake nail array mode with a combination of 200mm "I" type, 200mm "L", 300mm "I" type, and 300mm "L" type layers is often used for processing; for tobacco leaves with "module tobacco" specifications, combined with the tobacco leaf winding characteristics, a rake nail array mode with a combination of 200mm "I" type and 300mm "I" type layers is often used for processing. The utility model provides four quick-detachable and quick-install modular rake nails, and corresponding array combinations are made for different incoming material processing specifications. The quick-detachable rake nails of the leaf-threshing and redrying hot air leaf-moistening machine of the present invention provide a suggested modular transformation idea for the processing of tobacco leaves with different incoming material specifications, and provide a new idea for the integrated modularization in subsequent module conversion. Furthermore, in some embodiments of the present invention, this idea can be applied to other leaf-threshing and redrying processing equipment to achieve integrated modular transformation for different incoming material specifications.

[0034] The quick-detachable rake nails of the leaf moistening machine for threshing and redrying hot air leaf moistening provided by the embodiment of the utility model can meet the different rake nail usage modes for different incoming material specifications. At the same time, the quick-detachable design is adopted to replace the rake nail array, and the quick-detachable locking sleeve is used to greatly reduce the replacement and installation time of the rake nails; the rapid mode conversion of the rake nail arrangement of the leaf moistening machine can be realized for tobacco leaves of different specifications to meet the requirements of process instructions; the design is simple and the conversion is convenient, which solves the problem of poor processing effect of the leaf moistening process due to the difficulty of mode conversion; the manual operation is convenient, which avoids the high-risk risk of fire operation in the cylinder, reduces the difficulty of manual operation, and provides ideas for the subsequent modular transformation of the leaf threshing and redrying processing links.
