Description

Technical Field

[0001] This patent relates to the field of cigarette filter manufacturing technology, specifically to an adsorption device used in the manufacturing process of aerosol-generating products. Background Technology

[0002] In the field of cigarette filter manufacturing technology, ceramic discs are widely used in irregularly shaped filters due to their excellent adsorption properties, high temperature resistance, and chemical stability. They are used to filter harmful components in cigarette smoke, regulate the temperature of the smoke, and optimize the smoking experience.

[0003] Ceramic discs have a large specific surface area and a special porous structure, which can effectively trap smoke particles, tar and small molecule harmful components such as some heavy metals and polycyclic aromatic hydrocarbons in cigarette smoke through physical adsorption and electrostatic action, thereby reducing the entry of these substances into the human body and reducing the health hazards of smoking.

[0004] However, the porous structure inherent in ceramic sheets has become a key technological bottleneck restricting the efficient transportation and production of ceramic sheets.

[0005] The pores on and inside the ceramic sheet possess adsorption properties. During production, when an adsorption device is used to grasp, transfer, or position the ceramic sheet, the adsorption force generated by the device preferentially adsorbs and traps adsorption media such as air and gases in vacuum adsorption through the pores of the ceramic sheet. This significantly reduces the actual effective adsorption force between the adsorption device and the ceramic sheet, making it impossible to form a stable adsorption connection. On automated cigarette filter production lines, frequent occurrences of ceramic sheets falling off or shifting due to weak adsorption not only reduce production efficiency but also easily cause product quality defects, increasing the defect rate and production costs. Furthermore, the presence of pores can cause uneven force during adsorption, further affecting the positioning accuracy and stability of the ceramic sheet on the adsorption device.

[0006] Currently, existing technologies mainly attempt to solve the problem of ceramic sheet adsorption by improving the structure of the adsorption device, such as increasing the contact area of ​​the adsorption head and adjusting the adsorption pressure parameters. However, these solutions only optimize the adsorption device and do not provide an effective solution to the core problem of ceramic sheet porosity. They cannot fundamentally eliminate the negative impact of porosity on the adsorption effect and are insufficient to meet the technical requirements for efficient and stable adsorption of ceramic sheets in the cigarette filter production process.

[0007] Therefore, there is an urgent need for an adsorption device for the manufacturing process of aerosol-generated products to overcome the adsorption barrier caused by the pores of ceramic sheets and improve production efficiency and product quality. Utility Model Content

[0008] This patent aims to solve the problem of traditional adsorption devices being easily affected by pores when adsorbing porous ceramic sheets, and to achieve stable and efficient adsorption. This patent provides the following technical solution:

[0009] In a first aspect, an adsorption device for manufacturing aerosol-generating products is provided, comprising a body, an elastic element, a sealing tube, a suction tube, and a sleeve. The body includes a cavity and a pipe joint for connecting a negative pressure device. The cavity is connected to the pipe joint. The elastic element and the sealing tube are disposed within the cavity. The suction tube is disposed within the cavity and connected to the elastic element and the sealing tube. The sleeve is detachably disposed at the end of the suction tube. When the negative pressure device is turned on, the body, the suction tube, and the sleeve form a negative pressure, thereby causing the porous sheet to be adsorbed and connected to the sleeve in a staggered manner.

[0010] Furthermore, the sleeve includes through holes, and the perforated sheet includes filter holes, with the through holes and filter holes being staggered along the axial direction.

[0011] Furthermore, the cross-sectional shape of the through hole can be regular or irregular, and the regular shape can be one or more of the following: circle, square, triangle, ellipse, pentagon or hexagon.

[0012] Furthermore, the centerline of the straw, the centerline of the cavity, and the centerline of the elastic element coincide.

[0013] Furthermore, an elastic element is placed in the cavity and one end is connected to a straw. The elastic element deforms under negative pressure, allowing the straw to move within the cavity.

[0014] Furthermore, a sealing tube is installed at the junction of the straw and the cavity to prevent the negative pressure environment from being disrupted when the straw moves.

[0015] Furthermore, the number of cavities can be single or multiple.

[0016] Furthermore, there are multiple cavities, and each cavity, straw, and pipe connector corresponds to another cavity.

[0017] Furthermore, there are multiple cavities arranged in an array on the body.

[0018] Furthermore, the material of the porous sheet is ceramic, and the shape of the porous sheet can be regular or irregular.

[0019] This patent has the following beneficial effects:

[0020] 1. An adsorption device is provided for the manufacturing process of aerosol-generating products, comprising a body, an elastic element, a sealing tube, a suction tube, and a sleeve. The body includes a cavity and a pipe joint for connecting a negative pressure device. The elastic element and the sealing tube are disposed in the cavity. The suction tube is disposed in the cavity and connected to the elastic element and the sealing tube. When the negative pressure device is turned on, the body, the suction tube, and the sleeve form a negative pressure, thereby adsorbing and connecting the porous sheet with the sleeve in a staggered manner. When the negative pressure device is turned off, the porous sheet is released from the adsorption device.

[0021] 2. In this patent, the core sleeve design of the device plays a crucial role. It can flexibly change the area and shape of the suction nozzle. When adsorbing porous sheets, the area of ​​the suction nozzle can be misaligned with the holes on the porous sheet, fundamentally avoiding or significantly reducing the situation where the suction nozzle adsorbs into the holes. This design directly solves the problems of insufficient adsorption force and unstable adsorption caused by the correspondence between the suction nozzle and the holes in traditional adsorption devices. It ensures the stable and reliable adsorption effect on porous sheets, effectively reducing the probability of porous sheets falling off or being damaged due to adsorption problems during handling and processing, and ensuring the smooth progress of the production process.

[0022] 3. In this patent, the sleeve and the stepped holes of the suction tube are detachably connected, and the sleeve can be provided with one or more through holes with regular or irregular cross-sections. This design allows for convenient replacement of the appropriate sleeve according to the size, distribution of holes and shape of different porous sheets. Whether facing porous sheets with dense hole arrangement and special shape, or porous sheets of conventional size, the device can quickly adapt by changing the sleeve, which greatly expands the application range of the adsorption device, enhances its versatility and flexibility in different production scenarios, and meets diverse production needs.

[0023] 4. In this patent, the main body is provided with several arrayed cavities, and each cavity is equipped with a corresponding suction tube. This optimized design enables the simultaneous adsorption of multiple porous ceramic sheets. Compared with traditional single-port adsorption devices, this adsorption device can complete the adsorption and transfer of more ceramic sheets per unit time, which significantly improves the efficiency of production operations. Especially in the scenario of mass production of porous thin sheets, this efficient adsorption capacity can greatly shorten the production cycle and provide strong support for enterprises to increase production capacity.

[0024] 5. In this patent, the cavity of the adsorption device adopts a cylindrical design, and the compression spring, suction tube, and cavity are coaxial. This coaxial structural layout ensures that the components of the adsorption device are subjected to uniform force during operation, avoiding excessive local stress. For the adsorption device itself, this reduces problems such as component wear and deformation caused by uneven force, extends the overall service life of the device, and reduces the maintenance and replacement costs of the equipment. At the same time, uniform force also prevents the porous sheet from cracking or being damaged due to excessive local force, protecting the adsorbed porous sheet and reducing product loss.

Standard and extra-standard cigarettes, with a length of 75mm to 91mm and a circumference of 23mm to 25mm, are popular with many customers. Cigarette products of various sizes can also be manufactured with filters of different lengths. Generally, short filters are used for cigarette products with both short length and short circumference. Typically, filter tip lengths range from 15mm, used with "short" and "standard" cigarettes, to 30mm, used with "extra-long" and "extra-thin" cigarettes. The tipping paper in the longitudinal direction of the cigarette with a filter tip is, for example, 3mm to 10mm longer than the filter tip.

[0081] 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.

[0082] An adsorption device 100 for use in the manufacturing process of aerosol-generating products is readily understood to be used in the manufacturing process of aerosol-generating products, particularly in the handling, transportation, or picking up of porous sheets 200 in the aerosol-generating products that can filter aerosols.

[0083] In this embodiment, the aerosol generating product specifically refers to conventional cigarettes, and the perforated sheet 200 specifically refers to a porous ceramic sheet used for external filters of conventional cigarettes.

[0084] Please refer to Figures 1-2The adsorption device 100 includes a body 110, an elastic element 120, a sealing tube 130, a suction tube 140, and a sleeve 150. The body 110 includes a cavity 111 and a pipe joint 112 connected to a negative pressure device. The cavity 111 is connected to the pipe joint 112.

[0085] The top of the main body 110 is provided with a mounting hole 142 for fixing the adsorption device 100. The side of the main body 110 is provided with a cylindrical protrusion as a pipe connector 112. The pipe connector 112 has a pipe connection channel in the center. After the negative pressure device is connected to the pipe connector 112, the adsorption force acts from the pipe connection channel into the interior of the adsorption device 100.

[0086] Cavity 111 is located at the bottom of body 110. Cavity 111 is a cylindrical cavity that extends axially from the bottom end of body 110 toward the center of body 110. Cavity 111 is connected to the pipe connection channel on the side. It is easy to understand that the suction force of the negative pressure device is transmitted to cavity 111 from the pipe connection channel.

[0087] The cavity 111 is provided with an elastic element 120, a sealing tube 130 and a part of a suction tube 140. One end of the elastic element 120 is not fixed in the axial direction, while the other end is connected to the mounting hole 142 at the end of the suction tube 140. The space in the cavity 111 for the elastic element 120 is greater than the space occupied by the elastic element 120 in its natural state. The elastic element 120 can provide the necessary pressure when the sleeve 150 contacts the perforated sheet 200.

[0088] In this embodiment, the elastic element 120 is a compression spring.

[0089] The sealing tube 130 is a cylindrical structure sleeved on the rear section 145 of the straw. The sealing tube 130 fits against the inner wall of the cavity 111 and the outer wall of the straw 140 and is used to keep the cavity 111 in a sealed environment.

[0090] In particular, the centerline of the straw 140, the centerline of the cavity 111, and the centerline of the elastic element 120 coincide, which ensures that the components of the adsorption device 100 are subjected to uniform force during operation and avoids excessive local stress.

[0091] Please refer to Figures 3-4 The straw 140 is a cylindrical structure with a small diameter at the front and a large diameter at the rear. Most of the rear section 145 of the straw is located in the cavity 111, which allows the straw 140 to slide back and forth in the axial direction in the cavity 111 without leaving the cavity 111. The sealing tube 130 can keep the cavity 111 sealed even when the straw 140 slides back and forth.

[0092] The straw 140 includes a front section 144 and a rear section 145, which are integrally formed along the axial direction. A suction tube 143 is located at the center of both sections. A portion of the rear section 145 is disposed within the cavity 111. The smaller diameter of the front section 144 and the larger diameter of the rear section 145 result in the suction tube 143 having the same shape distribution as the diameter variations of the front and rear sections 144 and 145. A stepped hole 141 is provided on the end face of the front section 144, with a diameter larger than that of the suction tube 143. A sleeve 150 is detachably installed in the stepped hole 141.

[0093] A connecting channel is formed between the connecting pipe, cavity 111, suction pipe 143 and sleeve 150. When the negative pressure device is turned on, the adsorption force is transmitted from the connecting pipe head to the sleeve 150. The channel between the connecting pipe, cavity 111, suction pipe 143 and sleeve 150 forms a negative pressure. The elastic element 120 changes from an elongated state to a compressed state in the cavity 111 under the action of negative pressure. The rear section 145 of the suction pipe slides into the cavity 111. The negative pressure environment causes the front end face of the sleeve 150 to generate an adsorption force through the through hole 151 of the sleeve 150, thereby adsorbing the perforated sheet 200 onto the front end face of the sleeve 150.

[0094] It should be noted that the adsorption object of the adsorption device 100 needs to contain through holes 151 and be a lightweight sheet material, so that the adsorption force generated by the sleeve 150 can stably adsorb the porous sheet 200. However, the adsorption device 100 does not impose requirements on the number or distribution shape of the through holes 151 on the end face of the porous sheet 200. When the number or distribution shape of the filter holes 210 on the end face of the porous sheet 200 is different, the adsorption device 100 can adsorb the corresponding porous sheet 200 by changing the sleeve 150.

[0095] Specifically, the cross-sectional shape of the through hole 151 is a regular shape or an irregular shape. The regular shape is one or more of the following: circle, square, triangle, ellipse, pentagon or hexagon. In this embodiment, the shape of the through hole 151 is a single circle.

[0096] In this embodiment, please refer to Figure 5 The perforated sheet 200 is a sheet-like cylindrical structure. The material of the perforated sheet 200 is ceramic. The end face is distributed with sun-shaped filter holes 210. The filter holes 210 are cylindrical through holes with one filter hole 210 in the center. The other filter holes 210 are spaced apart from the central filter hole 210 by a ring and are distributed in a radial circumference around the center.

[0097] Specifically, the filter holes 210 of the porous sheet 200 and the through holes 151 of the sleeve 150 should be staggered in their projections in the axial direction. This allows the through holes 151 to directly act on the non-filter hole 210 portion of the end face of the porous sheet 200 during negative pressure adsorption, while the sleeve and the front end face of the suction tube 140 outside the through holes 151 can shield the adsorption holes on the porous sheet 200, thereby achieving a staggered adsorption connection between the porous sheet 200 and the sleeve.

[0098] Its working principle is as follows: When the adsorption device 100 is working, the main body 110 is connected to the negative pressure device through the pipe joint 112. After the negative pressure device is activated, a negative pressure is generated in the cavity 111 of the main body 110. Under the action of negative pressure, the suction tube 140 is subjected to an inward pulling force. At this time, the sleeve 150 contacts the porous sheet 200. Since the sleeve 150 can change the area and shape of the suction port at the other end of the suction tube 140, the area of ​​the suction port is misaligned with the filter hole 210 of the porous sheet 200, thereby avoiding or reducing the suction port adsorbing onto the filter hole 210 of the porous sheet 200.

[0099] When it is necessary to release the porous sheet 200, the negative pressure device stops working, the negative pressure in the cavity 111 disappears, and the adsorption on the porous sheet 200 is released.

[0100] Specifically, the bottom of the body 110 can have multiple cavities 111 arranged in an array. The number of cavities 111 corresponds one-to-one with the number of tube connectors 112 and the number of straws 140. The cavities 111 are arranged in parallel, and the straws 140 are also arranged in parallel. Each straw 140 can adsorb a single porous sheet 200. It is easy to understand that the more cavities 111 there are, the more porous sheets 200 can be adsorbed in a single operation.

[0101] In practical use, a suitable sleeve 150 is selected and installed in the stepped hole 141 of the suction tube 140, depending on the pore size of the porous sheet to be adsorbed. By selecting sleeves 150 with different through-hole 151 specifications, the area and shape of the suction port at the other end of the suction tube 140 are changed, so that the area of ​​the suction port is misaligned with the filter holes 210 on the porous sheet 200, thereby avoiding or reducing the suction port adsorbing onto the pores on the porous sheet 200 and ensuring the adsorption effect.

[0102] When the negative pressure device is turned off, the adsorption force transmitted from the connector head to the sleeve 150 disappears, and the channel between the connector channel, cavity 111, suction pipe 143 and sleeve 150 returns to atmospheric pressure. The elastic element 120 changes from a compressed state to an extended state in the cavity 111, and the rear section 145 of the suction pipe returns to its initial position in the cavity 111, so that the perforated sheet 200 adsorbed on the front end face of the sleeve 150 is released.

[0103] With this structural design, utilizing the replaceability of the sleeve 150 and the design of the through hole 151, combined with the arrayed cavity 111 and the suction tube 140, it can adapt to the adsorption requirements of different porous ceramic sheets, and improve the stability and efficiency of adsorption.
