Description

Technical Field

[0001] This patent relates to the technical field of reconstituted tobacco production equipment, specifically to a papermaking reconstituted tobacco cutting device and a reconstituted tobacco production system. Background Technology

[0002] Reconstituted tobacco using the papermaking method refers to the process of using waste materials such as tobacco stems, dust, and broken tobacco leaves from cigarette manufacturing to create sheet-like or filamentous recycled products, which are then used as cigarette fillers. Reconstituted tobacco plays an important role in cigarette production, not only reducing costs but also improving the intrinsic quality of cigarettes.

[0003] During the reconstituted tobacco production process, defects are inevitable due to factors such as human error and equipment malfunctions. Currently, when defects occur, manual intervention is required to stop the transfer of reconstituted tobacco and prevent them from entering the storage compartment. However, if manual intervention is not timely and defects do enter the storage compartment, the entire compartment of finished products will be subject to inspection, resulting in significant economic losses. Furthermore, manual intervention is time-consuming, labor-intensive, and unsafe. Utility Model Content

[0004] The purpose of this patent is to improve the production efficiency of reconstituted tobacco using the papermaking method, and to solve this technical problem:

[0045] The detailed features and advantages of this application are described below in the specific embodiments. The content of this description is sufficient to enable any person skilled in the art to understand the technical content of this application and implement it accordingly. Based on the specification, claims and drawings disclosed in this specification, a person skilled in the art can easily understand the related objectives and advantages of this application.

[0046] This patent will now be described with reference to the accompanying drawings, in which similar reference numerals denote similar elements. While specific structures and arrangements are discussed, it should be understood that this is done merely for illustrative purposes. Those skilled in the art will recognize that other structures and arrangements can be used without departing from the spirit and scope of this patent. It will be clear to those skilled in the art that this patent can also be used in a variety of other applications.

[0047] In this specification and claims, several terms will be used, and unless otherwise indicated, these terms will be defined to have the following meanings:

[0048] The singular forms “a” and “the” include their corresponding plural forms. “At least one” means one or more, and “more” means two or more. “At least one of the following” or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can be expressed as: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0049] All figures used to represent physical quantities should be considered to be, in all cases, modified by the terms "within the unavoidable margin of error" or "approximately". Therefore, the numerical values ​​presented herein are approximations and may vary depending on the desired properties sought to be obtained by this patent. The principles of equivalents, which are applied to a minimum and not intended to limit the scope of the claims, should be applied, for example, each value should be interpreted at least according to the reported significant digits and by applying conventional rounding techniques.

[0050] It should be understood that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. A and B can be singular or plural. Additionally, the character " / " in this article generally indicates an "or" relationship between the preceding and following related objects, but it can also represent an "and / or" relationship. Please refer to the context for a more accurate understanding.

[0051] The paper-making sheet referred to in this patent is a type of tobacco sheet. The paper-making reconstituted tobacco sheet uses tobacco materials or tobacco waste from cigarette manufacturing processes, such as tobacco dust, stems, tobacco leaf fragments, and some low-grade tobacco leaves, as raw materials. After soaking in water, solid-liquid separation is performed to separate the water-soluble and insoluble substances in the tobacco. The insoluble substances are pulped and then processed into fiber substrate using a papermaking machine, while the water-soluble substances are concentrated, reduced, and added to the substrate. Finally, after drying, the paper-making sheet is obtained. On the one hand, the paper-making sheet maximizes the utilization of tobacco raw materials, saving on cigarette costs. On the other hand, the paper-making sheet plays an important role in reducing the release of tar from cigarettes and thus reducing the harm of cigarettes.

[0052] Existing methods for producing tobacco sheets mainly include the slurry process and the papermaking process. The papermaking method, which produces tobacco sheets, is entirely different from the slurry method. Its physical and filling properties are far superior, effectively reducing tar and harmful substances in cigarette smoke, and it plays an increasingly important role in cigarette formulation. Because the papermaking process for reconstituted tobacco fully utilizes mature technologies and equipment from the papermaking industry, it has unparalleled advantages in production capacity compared to other reconstituted tobacco types such as the roll pressing and slurry processes. Through continuous and efficient material processing, large-scale production is achieved. Based on the different physicochemical performance requirements of the papermaking reconstituted tobacco products, significant adjustments can be made to the extraction, pulping, and papermaking processes to achieve quality control over the product's physical properties, thereby meeting the industrial processing performance needs of cigarette manufacturers.

[0053] The typical preparation method for tobacco sheets using the papermaking process involves the following steps: First, tobacco materials (tobacco stems, tobacco leaf fragments) are soaked and extracted with hot water. A solid-liquid separation step separates the water-soluble tobacco components from the insoluble components such as tobacco fibers. The resulting fibers are formed into sheet bases on a paper machine. The water-soluble components are then concentrated by distillation to obtain a tobacco concentrate. This concentrate is then impregnated or sprayed onto the sheet base, and finally dried to form tobacco sheets. In the process of manufacturing tobacco sheets using the papermaking method, traditional techniques have been adapted from papermaking methods.

[0054] All other terms used herein for special definition are intended to have the general meaning understood by one of ordinary skill in the art, and in particular, meaning that one of ordinary skill in the art, upon reading the claims, specification and drawings of this patent, can directly and without doubt determine how the technical solution of this patent can be implemented.

[0055] Even if there are incomplete descriptions, omissions, or ambiguities in the grammar, words, punctuation, graphics, symbols, etc. of the claims, specification, and drawings of this patent, a person skilled in the art can still arrive at the only correct understanding by reading the claims, specification, and drawings as a whole without extensive reasoning or experimentation, and effectively exclude various incorrect interpretations that are not aimed at achieving the purpose of this patent.

[0056] Those skilled in the art would first choose to read the claims, specification, and drawings of this patent to reasonably interpret the terms; secondly, they would choose to refer to the relevant definitions in other documents published by the applicant before the filing date to reasonably interpret the terms; thirdly, they would choose the references cited in this patent to reasonably interpret the terms; and finally, they would choose to combine the technical dictionaries, technical manuals, reference books, textbooks, national or industry technical standards, etc., commonly used by those skilled in the art to reasonably interpret the terms.

[0057] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0058] Example 1

[0059] refer to Figures 1-3 This patent first provides a cutting device for reconstituted tobacco leaves produced by a papermaking process, connected to a conveying device 300, including a cutting component 100 and a control component 200. The conveying device 300 is used to convey reconstituted tobacco leaves produced by a papermaking process 400. The cutting component 100 is used to cut the reconstituted tobacco leaves produced by a papermaking process 400 conveyed by the conveying device 300. The control component 200 is electrically connected to the cutting component 100 and is used to send a cutting signal to the cutting component 100.

[0060] Specifically, the cutting assembly 100 includes a drive unit, a cutting unit, and a support unit.

[0061] The drive unit provides power to the cutting unit and includes an external air source, a solenoid valve 170, and a stroke cylinder 110. The solenoid valve 170 is positioned between the external air source and the stroke cylinder 110 to control the air supply to the stroke cylinder 110, thereby controlling its movement. The stroke cylinder 110 moves up and down. After the serrated cutter 120 contacts the reconstituted tobacco leaf, it cuts it. The stroke cylinder 110 then drives the cutter back to its original position. Two sets of stroke cylinders 110 are provided.

[0062] The cutting section is used to cut reconstituted tobacco leaves for papermaking. The cutting section includes a serrated cutter 120 and a guide shaft 130. The serrated cutter 120 is a stainless steel cutter with a serrated shape. The guide shaft 130 is connected to a fixed bracket 140 and the serrated cutter 120. Four sets of guide shafts 130 are provided.

[0063] The bracket section is used to install the drive section and the cutting section. The bracket section includes a fixed bracket 140, a safety guard 150, and a fixed base 160.

[0064] The fixed bracket 140 is connected to the guide shaft 130. A safety guard 150 is positioned above the cutting assembly 100. The control assembly 200 also includes an audible and visual alarm. The audible and visual alarm 220 is used to issue an easily noticeable audible and visual alarm signal upon receiving a cutting command. The control assembly 200 also includes a cutting command transmission switch, which converts manual operation into a cutting command.

[0065] In this embodiment, the technical problem to be solved is that after the control component 200 issues a cutting command, the solenoid valve 170 is activated, starting the stroke cylinder 110. The cylinder 110 drives the serrated cutter 120 to move up and down. After the serrated cutter contacts the reconstituted tobacco leaf, it cuts it. After cutting, the cylinder drives the cutter back to its original position. The guide shaft 130 is used to ensure that the serrated cutter 120 can move in the up and down direction. Specifically, in this embodiment, as shown... Figure 1 As shown, cylinders 110 are located at both ends of the serrated cutter 120. The serrated cutter 120 is a stainless steel serrated cutter. The guide shaft 130 is connected to the fixed bracket 140 and the serrated cutter 120. The safety guard 150 is located above the cutting assembly 100. The fixed base 160 is used to support and fix the papermaking reconstituted tobacco cutting device on the reconstituted tobacco production line.

[0066] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, a control component 200 is also provided, which is electrically connected to a solenoid valve 170. After the cut-off command switch 230 sends a cut-off command, the solenoid valve 170 is activated and displayed on the control panel 210 on the control component 200. The operator can intuitively understand the operation of the papermaking reconstituted tobacco leaf cutting device.

[0067] The functions that this device can perform are described in detail below:

[0068] 1. Command control

[0069] When the control component 200 sends a cutting command through the cutting command switch 230, the papermaking reconstituted tobacco cutting device is activated to cut the reconstituted tobacco and the result is displayed on the control panel 21.

[0070] 2. Audible and visual alarm

[0071] When the control component 200 sends a cut-off command, the audible and visual alarm is activated in the audible and visual alarm 220 to remind the operator to handle the fault.

[0072] This invention modifies existing reconstituted tobacco equipment by rationally configuring the papermaking reconstituted tobacco cutting device, solving the problem that existing technologies can only stop the reconstituted tobacco leaf cutting manually, thus facilitating operation. Furthermore, by incorporating an audible and visual alarm 220, the papermaking reconstituted tobacco cutting device is automated and unmanned, reducing the operator's workload.

[0073] Example 2

[0074] This patent also relates to a reconstituted tobacco production system, including a conveying device, a storage device, and, for example, a papermaking reconstituted tobacco cutting device as described in Embodiment 1. The storage device is used to store the papermaking reconstituted tobacco conveyed by the conveying device. The papermaking reconstituted tobacco cutting device is located in front of the storage device, according to the material flow direction of the papermaking reconstituted tobacco.

[0075] This patent adds a papermaking-type reconstituted tobacco leaf cutting device to the conveying device between the drying oven and the storage device (e.g., a storage cabinet) of the reconstituted tobacco leaves produced by the papermaking process. Existing methods for preventing substandard reconstituted tobacco leaves from entering the storage cabinet involve manually blocking the reconstituted tobacco leaves exiting the drying oven.
