[0002] Heated cigarettes, favored by consumers due to their sensory similarity to traditional cigarettes, have experienced rapid growth in recent years. The core raw material for heated cigarettes is the tobacco core material in the heating section, which currently comes in three main forms: pellets, traditional cut tobacco, and reconstituted tobacco. Reconstituted tobacco, while retaining the active ingredients of natural tobacco, offers greater plasticity, homogenization, and controllability, making it the primary raw material for heated cigarette cores.
[0003] Methods for preparing reconstituted tobacco include the thick slurry method, roller pressing method, papermaking method, and dry method. In the thick slurry method, reconstituted tobacco is obtained by coating tobacco slurry containing tobacco powder onto an endless steel belt, followed by primary baking, peeling, secondary baking, and winding or shredding. The uniformity of the cast slurry thickness directly affects the thickness and moisture content of the reconstituted tobacco leaves after drying and forming. However, due to multiple factors such as the fluctuation of the slurry liquid level in the silo, the linear accuracy of the scraper processing, the flatness of the steel belt, and the equipment and operating accuracy, it is difficult to achieve consistent lateral uniformity in the cast slurry thickness, and the scraper as a whole is difficult to achieve local adjustment.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0036] like Figures 1 to 5 As shown, this embodiment provides a casting scraper device 100, including a scraper frame 120 and a plurality of scraper units 110, all of which are arranged in sequence along the working direction, the scraper unit 110 including a scraper seat 118 and a scraper body 116 movably connected to the scraper seat 118, the scraper seat 118 is fixed to the scraper frame 120, the scraper body 116 can move in the vertical direction relative to the scraper seat 118, and the scraper body 116 is elastically connected to the scraper seat 118 through an elastic member 114, the elastic member 114 is used to pull the scraper body 116 upward, the scraper body 116 extends along the working direction, one end of the scraper body 116 is provided with a male splicing end, and the other end is provided with a female splicing end, the two adjacent scraper bodies 116 are matched and connected through the male splicing end and the female splicing end, and the two adjacent scraper bodies 116 can slide relative to each other in the vertical direction.
[0037] The casting scraper device 100 is provided with a plurality of scraper bodies 116 that are matched and connected in sequence, so that the casting scraper device 100 has a casting scraper with multiple short-term local independent adjustment, thereby achieving segmented adjustment of the lateral uniformity of the casting thickness and ensuring the consistency of the lateral uniformity of the casting thickness. By providing a plurality of scraper units 110 arranged along the working direction, the casting scraper device 100 can flexibly adjust the relative position relationship between the scraper frame 120 and each scraper body 116 to meet the needs of large-area operations, thereby achieving efficient and continuous scraping operations. The design of the elastic member 114 allows the scraper body 116 to move freely in the vertical direction, playing the role of balancing the weight of the scraper body 116, thereby ensuring the working stability of the scraper body 116 under different working environments. The design of the male and female splicing ends allows for convenient and rapid relative sliding between adjacent scraper bodies 116, improving the flexibility and adaptability of the casting scraper device 100. This also reduces the risk of accidental displacement of the scraper bodies 116, helping to ensure the operational stability of the casting scraper device 100 and enabling the casting scraper device 100 to adapt to various process requirements. These improvements help improve the operating accuracy, stability, and efficiency of the casting scraper device 100, thereby meeting the needs of modern production.
[0038] Specifically, the elastic member 114 is a tension spring; and the number of the scraper units 110 is two to eight.
[0039] In this embodiment, the casting scraper device 100 is used in a process suitable for thick pulp method reconstituted tobacco. In other implementations of this embodiment, the casting scraper device 100 is used in other working environments requiring casting. The specific working environment is determined by those skilled in the art based on actual project conditions. The determination method is common knowledge in the art and will not be elaborated here.
[0040] When the casting scraper device 100 is applied to the process of thick slurry method reconstituted tobacco leaves, the separately arranged casting scraper can meet the width requirements of the subsequent production of slit small rolls, and ensure the thickness consistency of each section of reconstituted tobacco leaf small roll after slitting.
[0041] In this embodiment, the scraper unit 110 further includes two displacement sensors 111 . The displacement sensors 111 are fixed to the scraper seat 118 . The two displacement sensors 111 are respectively used to measure the displacement of the two ends of the scraper body 116 relative to the scraper seat 118 .
[0042] By providing a displacement sensor 111, the displacement of the ends of the scraper body 116 relative to the scraper holder 118 can be monitored in real time, thereby ensuring precise control of the scraper body 116 during operation. This improves the operating accuracy of the casting scraper device 100, ensures the accuracy and controllability of the scraping operation, and helps improve the quality of the operation. Furthermore, accurate understanding of the positions of the ends of the scraper body 116 facilitates the operator's calculation of the required position adjustment of the scraper body 116, thereby reducing the difficulty of adjustment for the operator.
[0043] Exemplarily, at least one connecting rod 115 is fixed to the scraper body 116 , and a linear bearing 113 is fixed to the scraper seat 118 . The number of linear bearings 113 is the same as the number of connecting rods 115 , and each connecting rod 115 is slidably engaged with a linear bearing 113 in the vertical direction.
[0044] With the help of the cooperation between the connecting rod 115 and the linear bearing 113, the scraper body 116 can slide smoothly in the vertical direction relative to the scraper seat 118, thereby improving the working efficiency and stability of the casting scraper device 100 and reducing errors in operation.
[0045] Furthermore, the linear bearing 113 extends in the vertical direction; the scraper seat 118 is movably connected to a micrometer screw 112, and the number of micrometer screws 112 and the connecting rod 115 are the same and correspond one to one; when the scraper body 116 moves upward, it stops at the connecting rod 115 and the micrometer screw 112 abutting against each other.
[0046] The contact between the micrometer screw 112 and the connecting rod 115 stops the scraper body 116, thereby limiting the upward movement of the scraper body 116 and improving operational accuracy. The micrometer screw 112 allows precise control of the range of movement of the scraper body 116 relative to the scraper holder 118, thereby enhancing the operating precision and controllability of the casting scraper apparatus 100. Specifically, the micrometer screw 112 has an adjustment accuracy of 10 microns.
[0047] In this embodiment, a locking member 117 is movably connected to the scraper seat 118 , and the locking member 117 can selectively lock and connect the scraper seat 118 and the scraper body 116 .
[0048] The design of the locking piece 117 can easily and quickly realize the locking and loosening of the scraper seat 118 and the scraper body 116, thereby enabling the casting scraper device 100 to complete the scraping operation while the scraper body 116 remains unchanged, thereby enabling the casting scraper device 100 to be applied to different process requirements, thereby expanding the application scenarios.
[0049] Furthermore, the projection of the scraper seat 118 in a plane perpendicular to the working direction is an inverted U-shape, the locking piece 117 is connected to one side wall of the scraper seat 118, and the scraper body 116 can be clamped between the other side wall of the scraper seat 118 and the locking piece 117, thereby improving the structural compactness and operational convenience of the casting scraper device 100.
[0050] The locking member 117 cooperates with the inverted U-shaped scraper holder 118, allowing the locking member 117 to be easily connected to one side of the scraper holder 118. This also facilitates the locking member 117 to press the scraper body 116 against the other side of the scraper holder 118, thereby locking the scraper body 116 through a clamping method. The above design optimizes the structure of the scraper holder 118, making it easier to lock and release the scraper body 116 with the locking member 117, while also reducing the space occupied by the casting scraper device 100.
[0051] Furthermore, the locking member 117 includes a locking bolt connected to a side wall of the scraper seat 118 .
[0052] By adopting a locking bolt as the specific form of the locking member 117, the structure of the casting scraper device 100 is further simplified, the difficulty of operating the locking member 117 on the scraper seat 118 is reduced, the convenience of locking and loosening operations is improved, and the overall reliability of the casting scraper device 100 is improved.
[0053] In this embodiment, the projection of the scraper body 116 in the horizontal plane is Z-shaped.
[0054] By joining two adjacent scraper bodies 116 in a Z-shaped pattern at the joint, the joint is ensured to be effective, avoiding the occurrence of casting bulges at the joint, thereby ensuring the quality of the work. The above improvements enable the scraper body 116 to adapt to more working scenarios and application requirements, and enhance the versatility and practicality of the casting scraper device 100.
[0055] like Figures 1 to 6 As shown, this embodiment further provides a steel belt conveyor system, including a steel belt conveyor 200 and the aforementioned casting scraper device 100. A conveyor steel belt 300 is mounted on the steel belt conveyor 200. The steel belt conveyor 200 is used to drive the conveyor steel belt 300, and the casting scraper device 100 is used to control the thickness of the cast wet film 600 carried by the conveyor steel belt 300. Specifically, the scraper frame 120 is fixed to the steel belt conveyor 200.
[0056] By combining a steel belt conveyor 200 with a casting scraper device 100, this steel belt conveyor system precisely controls the thickness of the wet cast film 600 carried on the conveyor belt 300, thereby improving production efficiency and product quality. The steel belt conveyor system enables continuous and stable operation, helping to reduce production costs and labor input.
[0057] In this embodiment, the steel belt conveyor system is applied to a casting machine for a reconstituted tobacco baking and forming machine. In other implementations of this embodiment, the steel belt conveyor system is applied to other casting equipment. The specific application scenario is determined by those skilled in the art based on actual engineering practices. The determination method is common knowledge in the art and will not be elaborated here.
[0058] Exemplarily, the steel belt conveying system also includes a casting storage bin 400 located upstream of the casting scraper device 100. The casting storage bin 400 contains tobacco slurry 500, which is used to apply tobacco slurry 500 on the conveying steel belt 300. The tobacco slurry 500 is converted into a casting wet film 600 on the conveying steel belt 300.
[0059] With the help of the setting of the cast film storage silo 400, the operation of smearing the tobacco slurry 500 on the conveyor steel belt 300 is realized, and the tobacco slurry 500 is converted into the cast film wet film 600, thereby simplifying the operation process, realizing the efficient production of the cast film wet film 600, improving the continuity and production efficiency of the production process, and ensuring the stability of product quality.
