Description

Technical Field

[0001] This invention relates to the field of heated non-combustible cigarette technology, and in particular, to a method for preparing a magnetically heated smoke-generating section. Background Technology

[0002] Heated tobacco products are a special type of tobacco product that has been under development in recent years. They are heated using electromagnetic heating or other methods, releasing flavor components and other substances from the tobacco. Because the tobacco does not participate in combustion, the production of harmful compounds due to high-temperature decomposition at 900℃ is avoided. This reduces harm to the body while providing consumer satisfaction and lowering environmental smoke pollution.

[0003] Currently, most commonly used magnetically heated tobacco-generating sections are prepared through tobacco suction forming. Equipment for this process is readily available, the manufacturing process is near-perfect, production costs are low, production speed is fast, and all types of tobacco can be produced. For example, Chinese invention patent CN110558606A provides a tobacco suction forming device for the ZJ17 cigarette machine, comprising: an air chamber, suction rollers, and suction ribbons. Multiple suction rollers are arranged within the air chamber, driving the mesh-like suction ribbons to rotate continuously. When process air passes through the air chamber, negative pressure is created in the mesh of the suction ribbons, attracting the tobacco shreds to form a tobacco bundle. An arc-shaped groove is arranged around the meshing surface of the suction rollers, allowing the suction ribbons to mesh along the arc-shaped grooves as the rollers rotate, thus forming an arc-shaped structure of the tobacco bundles attracted by the suction ribbons. This invention reduces cigarette production costs and improves the quality of tobacco processing.

[0004] However, the magnetically heated smoke-generating section formed by wire suction does not contain a sensor. A sensor needs to be inserted into the magnetically heated smoke-generating section prepared after wire suction forming, or a special lighter with a sensor pin is required to electromagnetically heat the smoke-generating section to generate smoke.

[0005] While designs exist that incorporate receptors into the tobacco-generating section, they require entirely new manufacturing processes. These processes only allow for the use of a funnel-shaped coiling method for specific types of ordered tobacco, relying entirely on the pressure of this coiling process to press the receptor wire into the tobacco-generating section. Furthermore, additional tension rollers for the receptor wire are needed after the coiling point. This approach has several drawbacks: First, the entirely new equipment and process render all older tobacco-drawing equipment obsolete. Second, the tobacco-generating process in this new equipment is still imperfect, resulting in high production costs and slow production speeds. Third, it can only process specific types of ordered tobacco. Fourth, the receptor wire and the outer paper conveyor are independent, potentially leading to speed differences that could result in some tobacco-generating sections lacking or having extra receptors, causing instability in the final smoke output.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable method for preparing a magnetically heated smoke-generating section. Summary of the Invention

[0007] The purpose of this invention is to provide a method for preparing a magnetically heated smoke-generating section. By directly adding a sensor implantation part to the existing tobacco-suction forming equipment, the sensor can be effectively implanted in the smoke-generating section without changing the equipment. This method not only retains the stable, efficient, and low-cost characteristics of tobacco-suction forming, but also allows for the preparation and production of various types of tobacco. The implanted sensor is also transported along with the suction cable, ensuring the smoking temperature of the resulting smoke-generating section.

[0008] To achieve the above objectives, the present invention employs the following technical solution:

[0009] A method for preparing a magnetically heated smoke-generating section includes the following steps:

[0010] S1: Feed the tobacco into the tobacco sucking area;

[0011] S2: When the suction ribbon wheel is running, it drives the suction ribbon to run continuously, causing the suction ribbon to bend into an arc shape and enter the suction area;

[0012] S3: By creating negative pressure in the suction area, the tobacco fed into the suction area is adsorbed onto the suction belt to form a tobacco strip;

[0013] S4: Heat and apply adhesive to the smoke-generating strip in the edge sealing area to seal the edges;

[0014] S5: After cutting the smoke-generating strips, smoke is emitted;

[0015] When performing step S1, a sensor implantation part is provided in front of the tobacco suction area to feed the sensor in the sensor implantation part together with the tobacco into the tobacco suction area.

[0016] When performing step S3, the sensor and tobacco fed into the suction area are adsorbed onto the suction tape to form a magnetically heated tobacco strip;

[0017] In step S5, the magnetically heated smoke-generating section is cut to obtain the magnetically heated smoke-generating section, which then emits smoke.

[0018] As a preferred embodiment of the present invention, the receptor implantation part includes a receptor unwinding reel and a receptor introduction head, such that when step S1 is performed, the receptors on the receptor unwinding reel are unwound and guided to the fiber suction area through the receptor introduction head.

[0019] As a preferred embodiment of the present invention, the number of the sensory reel is at least one.

[0020] As a preferred embodiment of the present invention, a sensor forming hole is provided between the sensor inlet head and the sensor unwinding reel, such that the sensor is bent when passing through the sensor forming hole before step S1 is performed, and the extension direction of the bent part of the sensor is the same as the extension direction of the sensor.

[0021] As a preferred embodiment of the present invention, the sensory forming hole includes an L-shaped hole, an M-shaped hole, an N-shaped hole, and a C-shaped hole.

[0022] As a preferred embodiment of the present invention, a speed sensor is provided between the sensor inlet head and the sensor unwinding reel. The speed sensor is electrically connected to the speed sensing part of the suction ribbon, so that when step S3 is executed, it is determined in real time whether the transmission speed of the suction ribbon and the steel coil are the same. If they are the same, no operation is performed; otherwise, an alarm is issued.

[0023] As a preferred embodiment of the present invention, a buffer zone is provided between the sensor unwinding reel and the sensor inlet head.

[0024] As a preferred embodiment of the present invention, the sensor introduction head is connected to a horizontal adjustment block and an vertical adjustment block, so that when step S3 is performed, the position of the sensor introduction head is adjusted by the horizontal adjustment block and the vertical adjustment block, thereby adjusting the position of the sensor implanted into the smoke-generating section strip.

[0025] As a preferred embodiment of the present invention, when performing step S5, the implantation position of the receptor is obtained during the cutting of the smoke-generating segment, and a feedback adjustment signal is sent to the horizontal adjustment block and the vertical adjustment block.

[0026] As a preferred embodiment of the present invention, a dynamic compensation roller is provided between the sensor inlet head and the sensor unwinding reel to adjust the sensor unwinding tension.

[0027] The beneficial effects of the magnetic heating smoke-generating section preparation method of the present invention are as follows: the sensor implantation part is added directly to the original tobacco suction forming equipment, and the sensor can be effectively implanted in the smoke-generating section without changing the equipment. It not only retains the stable, efficient and low-cost characteristics of tobacco suction forming, but also can be used to prepare and produce various tobaccos. The implanted sensor is also transported along with the suction wire, and the smoking temperature of the resulting smoke-generating section is guaranteed. Attached Figure Description

[0028] Figure 1 This is a schematic flowchart of a method for preparing a magnetically heated smoke-generating section according to the present invention. Detailed Implementation

[0029] The following are specific embodiments of the present invention, which further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement of modules and structures set forth in these embodiments does not limit the scope of the invention.

[0031] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0032] Techniques, methods, and systems known to a person skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the license specification.

[0033] Example 1: As Figure 1 The illustration shows only one embodiment of the present invention. A method for preparing a magnetically heated smoke-generating section includes the following steps:

[0034] A method for preparing a magnetically heated smoke-generating section includes the following steps:

[0035] S1: Feed the tobacco into the tobacco sucking area;

[0036] S2: When the suction ribbon wheel is running, it drives the suction ribbon to run continuously, causing the suction ribbon to bend into an arc shape and enter the suction area;

[0037] S3: By creating negative pressure in the suction area, the tobacco fed into the suction area is adsorbed onto the suction belt to form a tobacco strip;

[0038] S4: Heat and apply adhesive to the smoke-generating strip in the edge sealing area to seal the edges;

[0039] S5: After cutting the smoke-generating strips, smoke is emitted;

[0040] When performing step S1, a sensor implantation part is provided in front of the tobacco suction area to feed the sensor in the sensor implantation part together with the tobacco into the tobacco suction area.

[0041] The sensor is a strip-shaped structure made of metal materials such as steel strip, aluminum strip, and alloy strip. After the metal sensor strip is implanted in the smoking section, it can sense and generate heat in the electromagnetic environment of the cigarette lighter, thereby stimulating the tobacco in the smoking section to produce smoke.

[0042] Of course, the sensory tissue is drawn out from the sensory implantation part and led to the tobacco absorption area, where the sensory tissue is fed into the tobacco absorption area together with the tobacco.

[0043] When performing step S3, the sensor and tobacco fed into the suction area are adsorbed onto the suction tape to form a magnetically heated tobacco strip;

[0044] The negative pressure generated at the suction belt attracts the tobacco, thus forming a structure in which the suction belt covers the outer periphery of the tobacco. In this invention, the sensor belt is fed into the suction area together with the tobacco, so that the suction belt covers the tobacco and the sensor belt. The suction belt squeezes and clamps the tobacco and the sensor belt in the middle of the suction belt. During the suction belt transmission process, the tobacco and the sensor belt are clamped and transmitted to form a magnetically heated tobacco-generating segment. The sensor belt is passively transmitted, that is, the sensor implantation part does not require the power of the sensor belt to be fed.

[0045] Of course, in the magnetically heated smoking section, the sensor band is located in the middle of the tobacco filling area, so that when the sensor heats up, it can evenly stimulate the surrounding tobacco to produce smoke.

[0046] It should be noted that the production of this invention can be carried out using conventional tobacco suction equipment, except that a long strip of sensor is added in the middle of the smoking section, and the length of the sensor is the same as the length of the smoking section. Conventional tobacco suction processes can suck and shape disordered tobacco shreds, so the magnetically heated smoking section strip in this invention can also suck and shape disordered tobacco shreds. Of course, it can also suck and shape ordered tobacco shreds.

[0047] In step S5, the magnetically heated smoke-generating section is cut to obtain the magnetically heated smoke-generating section, which then emits smoke.

[0048] The middle part of the obtained long magnetic heating smoke-generating segment is the sensor strip, the outer side of the sensor strip is tobacco, and the outer side of the tobacco is the suction strip. At this point, the magnetic heating smoke-generating segment can be cut to obtain smoke-generating segments.

[0049] In this invention, the receptor implantation unit includes a receptor unwinding reel and a receptor introduction head, such that when step S1 is performed, the receptors on the receptor unwinding reel are unwound and guided to the fiber suction area through the receptor introduction head.

[0050] This invention discloses a method for preparing a magnetically heated smoke-generating section. It directly adds a sensor implantation part to the existing tobacco-suction forming equipment, and can effectively implant the sensor in the smoke-generating section without changing the equipment. It not only retains the stable, efficient and low-cost characteristics of tobacco-suction forming, but also can be used to prepare and produce various types of tobacco. The implanted sensor is also transported along with the suction wire, ensuring the smoking temperature of the resulting smoke-generating section.

[0051] Example 2: As before Figure 1 The above is merely one embodiment of the present invention. Based on Embodiment 1, in the method for preparing a magnetically heated smoke-generating section of the present invention, the number of sensor unwinding reels is at least one, and multiple sensor unwinding reels can be provided so that multiple sensor strips can be used alternately.

[0052] In this invention, a sensor forming hole is provided between the sensor inlet head and the sensor unwinding reel, so that the sensor is bent when passing through the sensor forming hole before step S1 is executed, and the extension direction of the bent part of the sensor is the same as the extension direction of the sensor.

[0053] Here, the sensor forming hole includes L-shaped holes, M-shaped holes, N-shaped holes, V-shaped holes, and C-shaped holes. In reality, when the sensor tape is unwound, its cross-sectional area is a straight-line sensor tape. After passing through the sensor forming hole, the cross-sectional area of ​​the sensor tape includes any structure that can be formed by bending a straight-line component. Therefore, the shape of the sensor forming hole can be many types, including but not limited to L-shaped, M-shaped, N-shaped, V-shaped, and C-shaped holes.

[0054] By bending the linear sensor belt, not only can the structural strength of the sensor belt be increased, but the friction between the sensor belt and the tobacco in the suction area can also be increased, so that the sensor belt can be better passively pulled and transmitted by the suction belt.

[0055] In one embodiment of the present invention, a speed sensor is provided between the sensor inlet head and the sensor unwinding reel. The speed sensor is electrically connected to the speed sensing part of the suction tape, so that when step S3 is executed, it can be determined in real time whether the transmission speed of the suction tape and the steel coil are the same. If they are the same, no operation is performed; otherwise, an alarm is issued. When step S3 is executed, after the suction tape wraps around the tobacco and the sensor tape, it is equivalent to clamping the sensor tape, so that the sensor tape is synchronously transmitted with the suction tape under the action of friction. The sensor is passively transmitted. In order to ensure that a sensor tape is provided at every point in the length direction of the smoke-generating section, the sensor tape and the suction tape need to be transmitted synchronously and at the same speed. Once there is a speed difference between the two, it must be that the sensor tape is not clamped and is not transmitting, and an alarm needs to be issued.

[0056] As an embodiment of the present invention, a buffer area is provided between the sensor unwinding reel and the sensor inlet head. When multiple sensor unwinding reels are used alternately, the sensor tapes on two unwinding reels need to be welded together. At this time, the sensor tape at the unwinding reel stops transmitting. In order to avoid the suction tape also stopping, a buffer area can be provided between the sensor unwinding reel and the sensor inlet head. Before welding, a portion of the sensor tape is buffered and accumulated in the buffer area. When the sensor tape at the unwinding reel stops transmitting after welding, the sensor tape in the buffer area continues to transmit and feed normally, so the suction tape does not need to stop.

[0057] Of course, an active transfer roller can be set at the end of the buffer area near the sensor unwinding reel. Normally, the conveying speed of the active transfer roller is the same as the conveying speed of the suction tape. When the sensor tape is buffered into the buffer area, the conveying speed of the active transfer roller can be increased to accumulate a portion of the sensor tape in the buffer area.

[0058] As an embodiment of the present invention, the sensor introduction head is connected with a horizontal adjustment block and an up-down adjustment block, so that when step S3 is executed, the position of the sensor introduction head is adjusted by the horizontal adjustment block and the up-down adjustment block, thereby adjusting the position of the sensor implanted into the tobacco strip, so that the sensor strip is located exactly in the middle of the tobacco area.

[0059] As an embodiment of the present invention, when performing step S5, the implantation position of the receptor is obtained when the smoke-generating segment is cut, and a feedback adjustment signal is sent to the horizontal adjustment block and the vertical adjustment block.

[0060] As an embodiment of the present invention, a dynamic compensation roller is provided between the sensor inlet head and the sensor unwinding reel to adjust the sensor unwinding tension and prevent the sensor belt from being damaged due to excessive force.

[0061] This invention discloses a method for preparing a magnetically heated smoke-generating section. It directly adds a sensor implantation part to the existing tobacco-suction forming equipment, and can effectively implant the sensor in the smoke-generating section without changing the equipment. It not only retains the stable, efficient and low-cost characteristics of tobacco-suction forming, but also can be used to prepare and produce various types of tobacco. The implanted sensor is also transported along with the suction wire, ensuring the smoking temperature of the resulting smoke-generating section.

[0062] This invention is not limited to the specific embodiments described above, and various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made to the above embodiments based on the technical essence of this invention should be included within the scope of protection of this invention.
