Description

Technical Field

[0001] This utility model relates to the field of tobacco preparation technology, and in particular to a slurry-based reconstituted tobacco leaf stripping system. Background Technology

[0002] Reconstituted tobacco leaf preparation methods include slurry method, roll pressing method, papermaking method, and dry method. Among them, slurry method reconstituted tobacco leaf is obtained by casting tobacco pulp containing tobacco powder onto an annular steel belt, followed by primary baking, peeling, secondary baking, winding or cutting.

[0003] The stripping process mainly involves using the stripping blades of the stripping system to peel the reconstituted tobacco leaves, which have been dried to a certain moisture content, from the steel belt. The leaves then undergo a secondary curing stage for final dehydration. The effectiveness of the stripping directly affects the surface quality of the reconstituted tobacco leaves. However, during production, the stripping blades gradually wear down and become dull over time, requiring timely replacement. This disrupts production continuity, causes losses, and poses certain quality risks. Utility Model Content

[0004] The purpose of this invention is to provide a slurry-based reconstituted tobacco leaf stripping system that avoids prolonged use of the same part of the stripping blade, extends the service life of the stripping blade, maintains the sharpness of the blade during stripping, improves the quality of the stripping process, reduces the frequency of blade replacement, and reduces production losses.

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

[0006] A slurry-based reconstituted tobacco leaf stripping system is used to strip reconstituted tobacco leaves attached to the support surface of a slurry casting steel belt. The slurry-based reconstituted tobacco leaf stripping system includes:

[0007] An unwinding module is disposed on one side of the tobacco casting steel strip, and the unwinding module includes a fixed cutter shaft;

[0008] The peeling knife is divided into a part to be used, a flattening part and a winding part. The part to be used is wound and sleeved on the fixed knife shaft. The blade of the flattening part can contact the tobacco casting steel strip and cover the width of the tobacco casting steel strip along the conveying direction to peel off the reconstituted tobacco leaf. The length of the flattening part remains unchanged.

[0009] A winding module is provided on the other side of the tobacco casting steel strip. The winding module is provided with a winding knife shaft. The winding part is connected to the winding knife shaft. The winding knife shaft can rotate to gradually wind and sleeve the stripping knife on the winding knife shaft, so that part of the flat part gradually becomes the winding part and part of the unused part gradually becomes the flat part.

[0010] As an optional technical solution for the slurry-based reconstituted tobacco leaf stripping system, the slurry-based reconstituted tobacco leaf stripping system further includes a grinding module, which is disposed between the tobacco slurry casting steel belt and the winding module, and the grinding module can grind the blade.

[0011] As an optional technical solution for the slurry-based reconstituted tobacco leaf stripping system, the slurry-based reconstituted tobacco leaf stripping system further includes a fixing module, which includes a rotating arm bracket. The end of the flat portion away from the blade is fixed to the rotating arm bracket, and the rotating arm bracket enables the flat portion to rotate around the rotating axis of the rotating arm bracket.

[0012] As an optional technical solution for the thick slurry reconstituted tobacco leaf stripping system, the fixing module includes an airbag assembly, which includes an airbag, a rotating blade liner, and a connecting blade holder. The connecting blade holder is fixedly connected to the rotating arm bracket, and the rotating blade liner supports and fits against the flat portion. The rotating blade liner and the connecting blade holder are connected at intervals through the airbag, and the airbag can be inflated to make the rotating blade liner rotate.

[0013] As an optional technical solution for the thick slurry reconstituted tobacco leaf stripping system, the air bladder includes a first air bladder and a second air bladder, which are spaced apart between the rotating blade liner and the connecting blade holder. The first air bladder can be inflated to bring the blade closer to the tobacco slurry casting steel belt, and the second air bladder can be inflated to move the blade away from the tobacco slurry casting steel belt.

[0014] As an optional technical solution for the thick slurry reconstituted tobacco leaf stripping system, the winding module includes a servo motor, which can control the rotation of the winding cutter shaft.

[0015] As an optional technical solution for the slurry-based reconstituted tobacco leaf stripping system, a warning section is provided at the end of the part to be used that is away from the flattened part. The unwinding module includes a warning sensor, which is communicatively connected to the servo motor. When the warning sensor detects that the warning section has been converted to the flattened part, the servo motor brakes the winding cutter shaft.

[0016] As an optional technical solution for the slurry-based reconstituted tobacco leaf stripping system, the fixed cutter shaft is configured as an air-expanding shaft.

[0017] As an optional technical solution for the slurry-based reconstituted tobacco leaf stripping system, the slurry-based reconstituted tobacco leaf stripping system includes a stripping knife temperature control module.

[0018] As an optional technical solution for the slurry-based reconstituted tobacco leaf stripping system, the slurry-based reconstituted tobacco leaf stripping system includes a tray module, which is used to receive and transfer the stripped reconstituted tobacco leaves.

[0019] The beneficial effects of this utility model are:

[0020] The slurry-based reconstituted tobacco leaf stripping system provided by this utility model is used to strip reconstituted tobacco leaves attached to the backing surface of the slurry cast steel strip, and includes an unwinding module, a stripping knife, and a winding module. The unwinding module is located on one side of the tobacco casting steel belt and includes a fixed cutter shaft. The peeling blade is divided into a usable part, a flattened part, and a winding part. The usable part is wound and sleeved on the fixed cutter shaft. The blade of the flattened part can contact the tobacco casting steel belt and cover the width of the tobacco casting steel belt along the conveying direction to peel off the reconstituted tobacco leaves. The winding module is located on the other side of the tobacco casting steel belt and is equipped with a winding cutter shaft. The winding part is connected to the winding cutter shaft. The winding cutter shaft can rotate to gradually wind and sleeve the peeling blade on the winding cutter shaft. While ensuring that the length of the flattened part remains unchanged, part of the flattened part gradually turns into the winding part, and part of the usable part gradually turns into the flattened part. The contact part between the peeling blade and the tobacco casting steel belt is updated in real time, avoiding the use of the same part of the blade on the peeling blade for a long time, extending the service life of the peeling blade, and maintaining the sharpness of the blade during peeling, improving the quality of the peeling process, reducing the frequency of blade changes, and reducing production losses.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. 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. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] like Figures 1 to 3As shown in the figure, this utility model discloses a slurry-based reconstituted tobacco leaf stripping system for stripping reconstituted tobacco leaves attached to the backing surface of a slurry-casting steel belt 100. A steel belt drive roller 110 is provided on the other side of the slurry-casting steel belt 100, which can drive the slurry-casting steel belt 100 to move along the conveying direction. The slurry-based reconstituted tobacco leaf stripping system includes an unwinding module, a stripping blade 300, and a winding module. The unwinding module is located on one side of the slurry casting steel belt 100 and includes a fixed blade shaft 210 to fix the rolled stripping blade 300. The stripping blade 300 is divided into a usable portion 310, a flattened portion 320, and a winding portion 330. The usable portion 310 is wound and sleeved on the fixed blade shaft 210. The blade of the flattened portion 320 can contact the slurry casting steel belt 100 and cover the width of the slurry casting steel belt 100 along the conveying direction to strip the reconstituted tobacco leaf. The winding module is located on the other side of the slurry casting steel belt 100 and is equipped with a winding blade shaft 410. The winding portion... 330 is connected to the take-up knife shaft 410. The take-up knife shaft 410 can rotate to gradually wind and sleeve the stripping knife 300 onto the take-up knife shaft 410. While ensuring that the length of the flat part 320 remains unchanged, part of the flat part 320 gradually transforms into the take-up part 330, and part of the unused part 310 gradually transforms into the flat part 320. The contact part between the stripping knife 300 and the tobacco casting steel belt 100 is updated in real time, avoiding the use of the same part of the blade on the stripping knife 300 for a long time, extending the service life of the stripping knife 300, and maintaining the sharpness of the blade during stripping, improving the quality of the stripping process, reducing the frequency of knife replacement, and reducing production losses.

[0034] Specifically, the thick slurry reconstituted tobacco leaf stripping system also includes a grinding module 500. The grinding module 500 is located between the tobacco slurry casting steel belt 100 and the winding module. The grinding module 500 can perform real-time grinding on the used blades of the stripping knife 300 before winding and during its movement, so as to realize the reusability of the stripping knife 300 and save process loss costs. With the continuous movement and updating of the flat part 320 of the stripping knife 300, grinding is performed at the same time, and the stripping knife 300 can be used directly after winding.

[0035] For example, the slurry-based reconstituted tobacco leaf stripping system includes a stripping blade temperature control module, which can select and adjust the temperature of the stripping blade according to the current moisture content of the reconstituted tobacco leaf and the stripping situation of the stripping blade 300 on the reconstituted tobacco leaf, thereby improving the stripping effect, so as to better complete the stripping process and reduce the adhesion residue caused by excessive moisture content or the embrittlement and splashing caused by excessive moisture content.

[0036] Optionally, the slurry-based reconstituted tobacco leaf stripping system includes a tray module for receiving and transferring the stripped reconstituted tobacco leaves. The tray module can collect the stripped reconstituted tobacco leaves in a timely manner to prevent them from being lost or scattered, and allow them to directly enter the secondary drying process.

[0037] In this embodiment, the slurry-based reconstituted tobacco leaf stripping system further includes a fixing module 600. The fixing module 600 includes a rotating arm bracket 610. The end of the flat portion 320 away from the blade is fixed to the rotating arm bracket 610. The rotating arm bracket 610 enables the flat portion 320 to rotate around the rotating axis of the rotating arm bracket 610, thereby moving the position of the flat portion 320 and controlling the blade to timely adhere to the tobacco slurry casting steel strip 100 for stripping.

[0038] Furthermore, the fixed module 600 includes an airbag assembly 620, which includes an airbag, a rotating blade liner 623, and a connecting blade holder 624. The connecting blade holder 624 is fixedly connected to the rotating arm bracket 610. The rotating blade liner 623 supports the flattened portion 320. The rotating blade liner 623 and the connecting blade holder 624 are connected at intervals via the airbag. The airbag can be inflated to make the rotating blade liner 623 rotate. Through the expansion of the airbag and the lever principle, the peeling blade 300 is given more freedom of movement, so as to further change the contact angle between the blade of the peeling blade 300 and the tobacco casting steel belt 100, so that the blade is in close contact with the surface of the tobacco casting steel belt 100. At the same time, the angle between the blade and the conveying direction can be flexibly adjusted according to the thickness of the reconstituted tobacco leaf to seek a better peeling effect. Specifically, as shown below... Figure 2 As shown, the airbag includes a first airbag 621 and a second airbag 622. The first airbag 621 and the second airbag 622 are spaced apart and sandwiched between the rotating blade liner 623 and the connecting blade holder 624. The first airbag 621 can be inflated to bring the blade closer to the tobacco casting steel strip 100, and the second airbag 622 can be inflated to move the blade away from the tobacco casting steel strip 100.

[0039] Continue to refer to Figures 1 to 3 In this embodiment, the winding module includes a servo motor and an encoder. The winding module can control the rotation of the winding blade shaft 410 through the servo motor to wind up the peeling blade 300. The encoder and servo motor can jointly control the feed amount of the peeling blade 300.

[0040] Optionally, a warning section is provided at the end of the part to be used 310 away from the flattening part 320. The unwinding module includes a warning sensor, which is communicatively connected to a servo motor. When the warning sensor detects that the warning section has been converted to the flattening part 320, the servo motor brakes the winding knife shaft 410 to prevent the movement of the thick slurry reconstituted tobacco leaf stripping system from exceeding the limit, avoid the stripping knife 300 from falling off and going out of control, and improve the safety of the thick slurry reconstituted tobacco leaf stripping system.

[0041] Furthermore, the fixed blade shaft 210 is configured as a damped air expansion shaft, which is simple to install and place, has a short inflation operation time, high efficiency, and is convenient to disassemble and replace the stripping blade 300. In addition, the installation structure is stable and has a good service life.

[0042] 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
