Description

Tobacco Vacuum Rehumidification Turnover Box Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a tobacco vacuum rehumidification turnover box. Background Technology

[0002] Vacuum rehumidification is a key process in the tobacco processing production line. Its main function is to increase the moisture content and temperature of tobacco leaves, making them softer, easier to loosen, and improving their processing resistance. It also reduces the grassy and unpleasant odors of the tobacco leaves, thus improving their quality. The vacuum rehumidification process includes four stages: vacuuming, humidification, heat preservation, and reverse vacuuming. Currently, the vacuum rehumidification process typically uses steel turnover boxes to hold the tobacco leaves, facilitating their circulation within the system after opening the bales. Once the turnover box enters the vacuum rehumidification device, the tobacco leaves are in a vacuum environment, creating a pressure and temperature difference between the inside and outside of the tobacco leaves. Humidifying steam is then applied, and the steam entering the box is quickly absorbed by the tobacco leaves. Due to the temperature difference between the steam and the tobacco leaves inside the box, the steam condenses on the surface of the tobacco leaves and is absorbed, releasing heat of vaporization that raises the temperature of the tobacco leaves. This temperature increase further increases the rate at which moisture spreads and penetrates from the surface to the inner layers of the tobacco leaves, thus achieving rapid and stable rehumidification of the tobacco leaves within the box.

[0003] However, in actual production, the compression and stacking of tobacco leaves in the turnover box, especially the tobacco leaves near the bottom of the turnover box, are subject to greater compression, which can easily lead to the formation of clumps of tobacco leaves, i.e., the formation of excessively large or dense tobacco clumps. This increases the diffusion resistance and diffusion distance of the humidifying airflow, thereby reducing the permeability of the humidifying airflow to these tobacco clumps. As a result, the tobacco leaves in the turnover box may not be fully rehydrated, and the low rehydration rate will affect the subsequent processing and the final quality of the tobacco leaves. Summary of the Invention

[0004] The purpose of this utility model is to provide a tobacco vacuum rehumidification turnover box, which can prevent tobacco leaves from being squeezed and stacked in the turnover box to form tobacco leaf cakes, and improve the steam permeability inside the box, thereby improving the rehumidification rate of tobacco leaves and improving the quality of tobacco leaves.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A tobacco vacuum rehumidification turnover box is provided, including a box body and a breathable component. The box body includes a base and a side plate surrounding the base.

A plurality of first protrusions are provided at intervals on the side of the base facing the placement cavity. The outer surface of the first protrusions is set as a curved surface.

[0007] The ventilated component is located in the middle of the side of the base facing the placement cavity. The ventilated component has a ventilated channel that connects the placement cavity to the outside. The ventilated component has a plurality of vents that are connected to the ventilated channel and the placement cavity, respectively.

[0008] In one embodiment, the base includes a base plate and a support plate. The first protrusion is disposed on the base plate. The first protrusion has a venting cavity communicating with the venting channel. The two ends of the first protrusion abut against the two side plates respectively. An air inlet communicating with the steam hole is disposed on the side of the first protrusion that abuts against the side plates, and the air inlet is communicating with the venting cavity.

[0009] In one embodiment, the breathable component includes a breathable tube, the inside of which is hollow to form the breathable channel, and a plurality of breathable holes are provided on the tube wall, the plurality of breathable holes being evenly arranged on the tube wall.

[0010] In one embodiment, the first protrusion is further provided with a slot, the slot is provided with a through hole, one end of the vent tube is inserted into the vent cavity through the through hole, the end of the vent tube inserted into the vent cavity is provided with a vent, and the vent channel is connected to the vent cavity through the vent.

[0011] In one embodiment, the base plate and the support base are detachably connected, and a limiting component is movably disposed on one side of the side plate adjacent to the base plate. The limiting component has a first position and a second position. When the limiting component is in the first position, the limiting component is partially located in the placement cavity and directly above the base plate. When the limiting component is in the second position, the horizontal projection of the limiting component is located outside the base plate.

[0012] In one embodiment, the limiting component includes a limiting block, a limiting opening for the limiting block to pass through on the side plate, a fixing part on the limiting block, a connecting rod on the fixing part, and a first elastic locking connector on the connecting rod near one end of the side plate. The diameter of the connecting rod is smaller than the steam hole, and the size of the first elastic locking connector is larger than the steam hole. When the limiting component is in the first position, the limiting block is partially located in the placement cavity and directly above the bottom plate, while the connecting rod and the first elastic locking connector pass through the steam hole and are located in the placement cavity. When the limiting component is in the second position, the horizontal projection of the limiting block is located outside the bottom plate, while the connecting rod and the first elastic locking connector are located outside the housing.

[0013] In one embodiment, the base is provided with a placement slot for placing the limiting component, the size of the placement slot being adapted to the size of the limiting block.

[0014] In one embodiment, the limiting block is further provided with a second elastic snap-fit ​​connector, the orientation of the second elastic snap-fit ​​connector being opposite to that of the first elastic snap-fit ​​connector, and the placement groove is provided with a snap-fit ​​hole for engaging with the second elastic snap-fit ​​connector.

[0015] In one embodiment, a support block is provided on the side of the base facing away from the placement cavity, and the base is provided with an air supply hole communicating with the ventilation channel.

[0017] The beneficial effects of this utility model are:

[0018] This utility model discloses a tobacco vacuum rehumidification turnover box. By setting multiple first protrusions with curved outer surfaces at intervals on the base, the mutual compression between tobacco leaves falling to the bottom of the box is reduced, preventing the tobacco leaves inside the box from becoming too dense and forming excessively large or dense tobacco clumps. As a result, the resistance when steam enters the box is reduced, which is conducive to the flow of steam in the box, improves the efficiency and permeability of tobacco leaf rehumidification and heating, and thus improves the quality of tobacco leaves.

[0019] Furthermore, in traditional storage boxes, steam mainly enters the placement chamber through the opening at the top of the box and steam holes on the side panels. Steam struggles to reach the middle section near the bottom of the box, or the temperature and humidity decrease when steam reaches this area, making it difficult for the tobacco leaves near the middle and bottom of the box to achieve effective rehumidification and warming. In this invention, by installing a ventilated component at the middle position of the base facing the placement chamber, and introducing external steam into the placement chamber through the ventilated channel of the component, the tobacco leaves near the middle of the base can directly receive steam rehumidification and warming, improving the rehumidification rate of the tobacco leaves in the middle of the base and thus enhancing the quality of the tobacco leaves.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0034] As shown in Figures 1 to 7, a tobacco vacuum rehumidification turnover box according to this embodiment includes a box body 100 and a ventilation component 200. The box body 100 includes a base 110 and a side plate 120 surrounding the base 110. The base 110 and the side plate 120 form a placement cavity 130. A plurality of steam holes 121 are provided through the side plate 120. A plurality of first protrusions 140 are provided on the side of the base 110 facing the placement cavity 130. The outer surface of the first protrusions 140 is curved. The ventilation component 200 is located in the middle of the side of the base 110 facing the placement cavity 130. A ventilation channel 211 is provided inside the ventilation component 200 to connect the placement cavity 130 with the outside. A plurality of ventilation holes 212 are provided on the ventilation component 200. The ventilation holes 212 are respectively connected to the ventilation channel 211 and the placement cavity 130.

[0035] In this embodiment, by providing multiple first protrusions 140 with curved outer surfaces at intervals on the base 110, the mutual squeezing effect between tobacco leaves falling into the bottom of the box 100 can be effectively reduced, avoiding excessive squeezing of tobacco leaves in the box 100 to form excessively large or dense tobacco lumps. As a result, the resistance when steam enters the box 100 is reduced, which is conducive to the flow of steam in the box 100, improves the efficiency and permeability of tobacco leaf rehumidification and heating, and thus improves the quality of tobacco leaves.

[0036] Furthermore, in traditional turnover boxes, steam mainly enters the placement cavity 130 through the opening at the top of the box body 100 and the steam holes 121 on the side plate 120. Steam has difficulty reaching the middle position near the bottom of the box body 100, or the temperature and humidity decrease when steam reaches this position, making it difficult for the tobacco leaves near the middle and bottom of the box body 100 to achieve effective rehumidification and heating. In this invention, by setting a ventilating component 200 at the middle position on the side of the base 110 facing the placement cavity 130, and introducing external steam into the placement cavity 130 through the ventilating channel 211 of the ventilating component 200, the tobacco leaves near the middle position of the base 110 can be directly subjected to steam rehumidification and heating, improving the rehumidification rate of the tobacco leaves in the middle position of the base 110, which is beneficial to improving the quality of the tobacco leaves.

[0037] In one embodiment, the base 110 includes a base plate 111 and a support plate 112. A first protrusion 140 is disposed on the base plate 111. In actual operation, the cross-section of the base plate 111 is wavy or sinusoidal wavy, which is convenient for processing. A ventilated cavity 141 communicating with the ventilated channel 211 is provided inside the first protrusion 140. The two ends of the first protrusion 140 abut against the two side plates 120 respectively. An air inlet 142 communicating with the steam hole 121 is provided on the side of the first protrusion 140 that abuts against the side plate 120, and the air inlet 142 is communicating with the ventilated cavity 141.

[0038] In one embodiment, the ventilation component 200 includes a ventilation pipe 210. The ventilation pipe 210 is hollow, forming a ventilation channel 211. Multiple ventilation holes 212 are evenly arranged on the wall of the ventilation pipe 210 to ensure uniform ventilation and improve the rehumidification rate of the tobacco leaves. In this embodiment, the length of the ventilation pipe 210 is vertically oriented, allowing steam to be directly delivered to the middle and bottom of the placement cavity 130. This ensures that the tobacco leaves located near the middle and bottom of the placement cavity 130 receive sufficient rehumidification and heating, resulting in uniform rehumidification of the tobacco leaves in all positions within the placement cavity 130, improving the overall rehumidification rate and quality of the tobacco leaves.

[0039] In one embodiment, the first protrusion 140 is further provided with a slot 143, and the slot 143 is provided with an insertion hole 144 that penetrates the slot 143 to realize the insertion and engagement of the vent pipe 210 with the first protrusion 140. At the same time, when the vent pipe 210 is inserted, the slot wall of the slot 143 guides and positions the vent pipe 210, ensuring that the vent pipe 210 remains vertical, thereby ensuring that the length of the vent pipe 210 is maintained from the bottom to the middle of the placement cavity 130, ensuring the delivery of steam to the middle position of the placement cavity 130. One end of the vent pipe 210 is inserted into the vent cavity 141 through the insertion hole 144, and the end of the vent pipe 210 inserted into the vent cavity 141 has a vent opening. The vent channel 211 communicates with the vent cavity 141 through the vent opening to realize the conduction of steam.

[0040] Furthermore, a positioning block 213 is also provided on the vent pipe 210. The positioning block 213 is set on the outer wall of the vent pipe 210. When the vent pipe 210 is inserted into the slot 143 to a certain depth, the positioning block 213 abuts against the upper surface on both sides of the insertion hole 144 position of the first protrusion 140. At this time, the bottom of the vent pipe 210 is spaced apart from the support plate 112 so that the steam in the vent chamber 141 can enter the vent channel 211 through the vent at one end of the vent pipe 210 and enter the placement chamber 130 through the vent hole 212 to rehydrate and heat the tobacco leaves.

[0041] In one embodiment, the base plate 111 and the support base are detachably connected. A limiting component 300 is movably disposed on the side of the side plate 120 adjacent to the base plate 111. The limiting component 300 has a first position and a second position. When the limiting component 300 is in the first position, part of the limiting component 300 is located inside the placement cavity 130 and directly above the base plate 111, thereby limiting the base plate 111 and preventing it from directly detaching from the opening above the housing 100. When the limiting component 300 is in the second position, its horizontal projection is located outside the base plate 111, thus releasing the limiting effect on the base plate 111. The operator can then remove the base plate 111 through the opening above the housing 100, facilitating replacement, cleaning, and maintenance of the base plate 111.

[0042] In one embodiment, as shown in Figures 3 and 6, the limiting component 300 includes a limiting block 310. A limiting opening 122 is provided on the side plate 120 for the limiting block 310 to pass through. A fixing part 320 is provided on the limiting block 310. A connecting rod 330 is provided on the fixing part 320. A first elastic snap connector 340 is provided on the connecting rod 330 near the side plate 120. The diameter of the connecting rod 330 is smaller than that of the steam hole 121, and the size of the first elastic snap connector 340 is larger than that of the steam hole 121. When the limiting component 300 is in the first position, the limiting block 310 is partially located in the placement cavity 130 and directly above the bottom plate 111. The limiting block 310 achieves a limiting effect on the bottom plate 111. At this time, the connecting rod 330 and the first elastic snap-fit ​​connector 340 are located inside the placement cavity 130 through the steam hole 121. The first elastic snap-fit ​​connector 340 engages with the steam hole 121, thus fixing the limiting component 300 to the side plate 120. When the limiting component 300 is in the second position, the horizontal projection of the limiting block 310 is located outside the bottom plate 111. Releasing the limiting effect of the limiting block 310 on the bottom plate 111 allows the bottom plate 111 to be separated from the housing 100. At this time, the connecting rod 330 and the first elastic snap-fit ​​connector 340 are located outside the housing 100, releasing the fixed connection between the limiting component 300 and the side plate 120.

[0043] In one embodiment, as shown in Figure 3, the base 110 is provided with a placement groove 113 for placing the limiting component 300. The size of the placement groove 113 is adapted to the size of the limiting block 310. When the base plate 111 needs to be removed, the removed limiting component 300 is placed in the placement groove 113 to avoid loss. When the base plate 111 is put back into the housing 100, the limiting component 300 can be directly used in the placement groove 113 to limit and fix the base plate 111, which is simple and convenient to operate.

[0044] In one embodiment, the limiting block 310 is further provided with a second elastic snap-fit ​​connector 350, the orientation of the second elastic snap-fit ​​connector 350 is opposite to that of the first elastic snap-fit ​​connector 340, and the placement groove 113 is provided with a snap-fit ​​hole 1131 that snaps into the second elastic snap-fit ​​connector 350. By snapping the second elastic snap-fit ​​connector 350 into the snap-fit ​​hole 1131, the limiting component 300 can be fixed in the placement groove 113, thus preventing the limiting component 300 from coming out of the placement groove 113 and being lost.

[0045] In one embodiment, as shown in FIG6, a support block 114 is provided on the side of the base 110 facing away from the placement cavity 130, so that an air supply gap 150 is provided between the base 110 and the ground or workbench. The base 110 is provided with an air supply hole 1121 communicating with the ventilation channel 211, so that external steam is input from the air supply gap 150 and enters the ventilation channel 211 through the air supply hole 1121, thereby increasing the air intake volume and air intake efficiency of external steam entering the ventilation channel 211, improving the efficiency of steam in rehumidifying and heating the tobacco leaves in the box 100, thereby improving the quality of the tobacco leaves.

[0046] In one embodiment, as shown in FIG8, a plurality of second protrusions 160 are also provided at intervals on the base 110. The plurality of second protrusions 160 are evenly disposed on the outer surface of the first protrusion 140 and / or on the surface of the base 110 facing the placement cavity 130. The outer surface of the second protrusion 160 is curved to further reduce the mutual compression between tobacco leaves, avoid excessive compression between tobacco leaves to form excessively large or dense tobacco blocks, reduce the resistance of steam flow between tobacco leaves, and ensure the re-permeability of tobacco leaves.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
