[0001] Cross-reference to related applications

[0002] This application is based on and claims priority to Chinese Patent Application No. 202411585420.0, filed on November 7, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of mold technology, and in particular to an extrusion die head and extrusion mold for manufacturing aerosol-generated articles. Background Technology

[0004] In related technologies, extrusion dies used to manufacture aerosol-generated products by extrusion are generally equipped with a die head and a die core. The material is extruded from the die core to form the aerosol-generated product.

[0005] To improve production efficiency, some extrusion dies are equipped with multiple cores, and the material is extruded from each core, thus allowing multiple aerosols to be extruded simultaneously to generate products.

[0006] However, during the extrusion process, it is difficult to maintain a consistent extrusion speed at each die core. ， Therefore, in related technologies, extrusion dies with multiple cores are prone to inconsistent material output at each core, resulting in poor appearance and internal surface quality of the extruded aerosol products. This leads to significant material waste and increased production costs. Summary of the Invention

[0018] In one embodiment, the handwheel has a non-circular hole, and the force-applying part is inserted into the non-circular hole to achieve a detachable anti-rotation connection between the handwheel and the force-applying part.

[0019] In one embodiment, the outer surface of the regulating valve has a sealing groove arranged circumferentially along the regulating valve, and the extrusion die further includes a sealing ring disposed in the sealing groove and in sealing contact with the inner sidewall of the valve mounting channel.

[0020] In one embodiment, the valve mounting channel includes a first section and a second section, which are located on opposite sides of the discharge channel. A portion of the regulating valve is located in the first section and another portion is located in the second section. The portion of the regulating valve located in the first section and the portion of the regulating valve located in the second section are both provided with the sealing groove.

[0021] In one embodiment, the first housing has locking channels that communicate one-to-one with the valve mounting channels. The extending direction of the locking channels intersects with the extending direction of the valve mounting channels. The extrusion die includes locking members movably disposed within each of the locking channels. The locking members can switch between a locking position abutting against the corresponding regulating valve and an unlocking position avoiding the corresponding regulating valve by moving along the extending direction of the locking channels.

[0057] This application provides an extrusion die 100 for manufacturing aerosol-generating articles.

[0058] The aerosol generating product is used in conjunction with an electronic atomizing device having a heating element. Specifically, the aerosol generating product includes an aerosol generating matrix 200 (see Figure 19). The heating element heats and atomizes the aerosol generating matrix 200 to generate an aerosol for inhalation by the user or for use in medicine, beauty, etc.

[0059] There are various heating methods for heating elements. For example, heating methods include center heating and peripheral heating. Center heating refers to the heating element being inserted into the aerosol generating matrix 200 to bake and heat the aerosol generating matrix 200. Peripheral heating refers to the heating element being positioned around the aerosol generating matrix 200 to bake and heat the aerosol generating matrix 200. These heating methods can specifically include resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc., and are not specifically limited here.

[0060] The extrusion die 100 is used in conjunction with an extruder, such as a hydraulic plunger extruder, a twin-screw extruder, a single-screw extruder, etc., to manufacture all or part of an aerosol-generating product by extruding and molding the material.

[0061] Extrusion molding is a processing method in which material is fed into an extruder, and through the action between the extruder barrel and the screw, the material is pushed forward by the screw and continuously passed through the extrusion die 100 at the extruder outlet to form products or semi-finished products of various cross-sections. The material formed by extrusion molding is in the form of strips.

[0062] This application describes an example of using an extrusion die 100 to manufacture an aerosol generating matrix 200 in an aerosol generating article. It should be noted that the aerosol generating article may consist only of the aerosol generating matrix 200, or it may be a combination of the aerosol generating matrix 200 and other structures. For example, as needed, the aerosol generating article may also have functional sections at one or both ends of the aerosol generating matrix 200. The functional sections may only have a filtration function, or they may have both filtration and cooling functions. In some embodiments, all or part of the functional sections may also be manufactured using the extrusion die 100 in this application embodiment.

[0063] The specific structure of the aerosol generating matrix 200 is not limited here. Exemplarily, the aerosol generating matrix 200 may be made of the atomizing medium itself, such as a smoky flavoring medium. In other embodiments, the aerosol generating matrix 200 may also include a matrix and an atomizing medium disposed on the matrix. The matrix may be, for example, high-temperature resistant carbon fiber. In this way, by providing a matrix, the strength of the aerosol generating matrix 200 can be improved, and it can withstand a certain degree of high temperature without producing odor.

[0064] The specific composition of the aerosol generating matrix 200 is not limited here. For example, in one embodiment, the aerosol generating matrix 200 may include plant components, auxiliary components, smoke-generating agent components, adhesive components, etc.

[0065] In one embodiment, the plant-based ingredients are one or more combinations of raw tobacco leaves, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants, which are powdered after being crushed. The plant-based ingredients are the core source of the product's aroma. Endogenous substances in the plant-based ingredients, such as nicotine, enter the bloodstream through atomization, promoting the pituitary gland to produce dopamine, thereby generating a sense of physiological satisfaction.

[0066] In one embodiment, the auxiliary component can be one or more combinations of inorganic fillers, lubricants, and emulsifiers. The inorganic fillers include one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic fillers provide skeletal support for the plant components, and their micropores increase the porosity of the wall material after molding, thereby improving the aerosol release rate.

[0067] Lubricants include one or more of the following: candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. Lubricants can increase the flowability of particles, reduce friction between particles, result in a more uniform overall particle density, and also reduce the pressure required for mold forming, thus reducing mold wear.

[0068] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can, to some extent, slow down the loss of flavor substances during storage, increase the stability of flavor substances, and improve the sensory quality of the product. Emulsifiers (also known as surfactants) can reduce the interfacial tension between water-soluble and water-insoluble components in a mixture, and form a more robust film on the surface of microdroplets or an electric double layer on the surface of microdroplets due to the charge given by the emulsifier, preventing microdroplets from agglomerating and maintaining a homogeneous emulsion. Homogenizing two immiscible components through emulsification can improve the consistency of product quality.

[0069] The function of the smoke-generating agent is to produce a large amount of vapor upon heating, thereby increasing the amount of smoke in the smoke-generating product. In one embodiment, the smoke-generating agent may include, for example, one or more combinations of: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerol); an ester of a polyhydric alcohol (such as glyceryl monoacetate, glyceryl diacetate, or glyceryl triacetate); a monocarboxylic acid; a polycarboxylic acid (such as lauric acid, myristic acid) or an aliphatic ester of a polycarboxylic acid (such as dimethyl dodecanoate, dimethyl tetradecanoate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl lauryl acetate, triacetin, meso-erythritol, a mixture of diacetins, diethyl caprylate, triethyl citrate, methyl benzoate, phenylacetic acid methyl ester, ethyl vanillate, glyceryl tributate, and lauryl acetate).

[0070] In one embodiment, the adhesive component is a natural plant extract, a non-ionic modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, pullulan polysaccharide, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan. The adhesive achieves close contact with the product component materials through wetting at the interface, generating intermolecular attraction, thereby binding the powder, liquid, or other components. Furthermore, the use of a natural plant extract and a non-ionic adhesive avoids the release of harmful substances such as methanol, formaldehyde, and acrolein associated with colloidal modification, thus improving the safety of the product.

[0071] For example, the aerosol generating matrix 200 can be a particulate aggregate, which is a reconstituted tobacco medium, such as a reconstituted tobacco medium containing smoke-generating agents, tobacco, and other components. The particulate aggregate aerosol generating matrix 200 remains an integral medium after being heated and inhaled or after heating is stopped, and is not prone to disintegration and falling off. This solves the problems of thin sheet, filament, or loose particulate aerosol generating matrices in the prior art, such as loose sheet, shedding of filamentous components, and difficulty in cleaning.

[0072] Please refer to Figures 1 to 18. The extrusion die 100 of this embodiment includes an extrusion die head 10 and a die core 20.

[0073] The extrusion die 10 includes a first base 11 and regulating valves 12. The first base 11 has multiple discharge channels 11a. Each regulating valve 12 corresponds to one discharge channel 11a, and each regulating valve 12 is respectively located at the corresponding discharge channel 11a. Each regulating valve 12 adjusts the flow rate of the corresponding discharge channel 11a by adjusting its opening degree.

[0074] Each mold core 20 corresponds to a discharge channel 11a. Each mold core 20 is located at the corresponding discharge channel 11a and is downstream of the corresponding regulating valve 12 along the material flow direction.

[0075] Specifically, the discharge channel 11a on the first seat 11 is used both to install the mold core 20 and to allow materials to pass through.

[0076] The number of discharge channels 11a can be two or more.

[0077] The distribution of the discharge channels 11a on the first body 11 is not limited. For example, the discharge channels 11a can be arranged in a row, or in multiple rows when the number of discharge channels 11a is relatively large. In addition, the discharge channels 11a can also be arranged in various shapes such as wavy, circular, elliptical, or racetrack-shaped, and can also be randomly distributed on the first body 11.

[0078] The regulating valve 12 installed at each discharge channel 11a is used to regulate the flow rate of the corresponding discharge channel 11a. In other words, the flow rate of each discharge channel 11a can be independently regulated by the corresponding regulating valve 12.

[0079] Please refer to Figures 8, 10 to 12, 16 and 18. The regulating valve 12 has an open state and a closed state.

[0080] Please refer to Figures 8, 11, 12 and 16. When the regulating valve 12 is in the open state, the regulating valve 12 connects the discharge channel 11a, that is, the opening degree of the regulating valve 12 is greater than 0.

[0081] When the regulating valve 12 is in the open state, each regulating valve 12 can adjust its opening degree manually or automatically. Different opening degrees correspond to different degrees of opening of the regulating valve 12. For example, please refer to Figures 8, 11 and 16. When the opening degree of the regulating valve 12 reaches the maximum value, the flow area of ​​the discharge channel 11a reaches the maximum value, and the flow rate of the discharge channel 11a is also the maximum. Please refer to Figure 12. When the opening degree of the regulating valve 12 is greater than 0 and less than the maximum value, the flow area of ​​the discharge channel 11a is greater than 0 and less than the maximum value, and the flow rate of the discharge channel 11a is less than the maximum flow rate of the discharge channel 11a.

[0082] The regulating valve 12 can be adjusted in a stepless manner, that is, the opening of the regulating valve 12 can be any value between 0 and the maximum value (including 0 and the maximum value). Stepless adjustment can improve the convenience and accuracy of adjustment.

[0083] In other implementations, the control valve 12 can be adjusted in a stepped manner, that is, the opening of the control valve 12 is a number of fixed values ​​including 0 and the maximum value, and the control valve 12 can only be adjusted between the set fixed values.

[0084] Please refer to Figures 10 and 18. When the regulating valve 12 is in the closed state, the regulating valve 12 cuts off the discharge channel 11a. That is, the opening degree of the regulating valve 12 is 0, the flow area of ​​the discharge channel 11a is also 0, and the material cannot flow in the discharge channel 11a.

[0085] Please continue to refer to Figures 1 to 3, 6, 13 to 15. The die core 20 is used to extrude the aerosol generating matrix 200. That is, the material entering the discharge channel 11a is extruded from the die core 20 to form the aerosol generating matrix 200.

[0086] The number of mold cores 20 is the same as the number of discharge channels 11a, that is, one mold core 20 is provided at each discharge channel 11a. For example, the first base 11 shown in Figures 1 and 13 is provided with nine discharge channels 11a, and one mold core 20 is provided at each discharge channel 11a. That is to say, the number of mold cores 20 is also nine. The material is extruded from each mold core 20, so that nine aerosol generating matrices 200 can be extruded at the same time.

[0087] Please refer to Figures 8 and 16. The fact that each die core 20 is located downstream of the corresponding regulating valve 12 along the material flow direction means that for the regulating valve 12 and die core 20 set in the same discharge channel 11a, the material first passes through the regulating valve 12 and then is extruded from the die core 20.

[0088] Each regulating valve 12 can adjust the extrusion speed at each die core 20 by adjusting its own opening.

[0089] For example, during the operation of the extruder, if there are significant differences in the extrusion speed at different die cores 20, the opening of the regulating valve 12 corresponding to the die core 20 with a faster extrusion speed can be reduced to decrease the extrusion speed of that die core 20, or the opening of the regulating valve 12 corresponding to the die core 20 with a slower extrusion speed can be increased to increase the extrusion speed of that die core 20. This will ensure that the extrusion speed at each die core 20 is roughly consistent.

[0090] For example, a speed detection device can be used to detect the extrusion speed at each die core 20. The detection device can be installed on other equipment downstream of the extruder or on the extruder itself. For manual adjustment, the extruder can provide feedback to the operator via text, light, voice, etc., to remind the operator to manually adjust the opening of the corresponding regulating valve 12. For automatic adjustment, the control components on the extruder can adjust the opening of the corresponding regulating valve 12 based on the detection results of the detection device.

[0091] Since the speed of the material flowing through each discharge channel 11a can be made more consistent by adjusting the opening of the regulating valve 12 at each discharge channel 11a, the extrusion speed at each die core 20 can be made to be approximately consistent. Therefore, the extrusion die 100 of this application embodiment can better ensure that the output amount at each die core 20 can be approximately consistent, thereby effectively improving the molding quality of the extruded aerosol generation matrix 200, reducing material waste, and thus reducing production costs.

[0092] In one embodiment, referring to Figures 1, 5, 8, 10, 16, and 18, the regulating valve 12 has a valve orifice 12a that passes through the regulating valve 12 and communicates with the discharge channel 11a. The regulating valve 12 adjusts its opening by changing the flow area of ​​the valve orifice 12a through movement relative to the first seat 11.

[0093] Specifically, valve orifice 12a is used for material to pass through, and the flow area of ​​valve orifice 12a refers to the area through which material can pass through valve orifice 12a.

[0094] The regulating valve 12 is movably disposed on the first seat 11, meaning that the entire regulating valve 12 can move relative to the first seat 11. By moving relative to the first seat 11, the regulating valve 12 can change the position of the valve orifice 12a, thereby changing the flow area of ​​the valve orifice 12a. For example, referring to Figures 8 and 11, when the valve orifice 12a is in a position fully connected to the discharge channel 11a, the flow area of ​​the valve orifice 12a reaches its maximum value, and the flow rate of the discharge channel 11a reaches its maximum value. Referring to Figure 12, when the valve orifice 12a is in a position partially offset from the discharge channel 11a (i.e., the valve orifice 12a is partially blocked), the valve orifice 12a is partially connected to the discharge channel 11a. At the same time, as the degree of offset increases, the flow area of ​​the valve orifice 12a decreases accordingly. The smaller the flow area, the less connected the valve orifice 12a is to the discharge channel 11a, and the smaller the flow rate of the discharge channel 11a.

[0095] The regulating valve 12, by moving relative to the first seat 11, can be positioned to fully connect the valve orifice 12a with the discharge channel 11a, or to partially offset the valve orifice 12a from the discharge channel 11a. Furthermore, even when partially offset, the regulating valve 12 can move to a position with a different degree of offset from the discharge channel 11a. This allows the flow area of ​​the valve orifice 12a to change with the movement of the regulating valve 12, thereby achieving valve opening adjustment. This type of regulating valve 12 has a simple structure, is easy to manufacture, and is not easily damaged. Therefore, using this type of regulating valve 12 can both meet the requirements of valve opening adjustment and save on the manufacturing cost of the extrusion die 100.

[0096] In one embodiment, referring to Figures 8, 10 to 12, 16, and 18, the regulating valve 12 may be rotatably disposed on the first seat 11, and the portion of the regulating valve 12 with the valve hole 12a is located within the discharge channel 11a. That is, the regulating valve 12 changes the flow area connecting the valve hole 12a and the discharge channel 11a by rotating relative to the first seat 11.

[0097] Please refer to Figure 12. When the regulating valve 12 is rotated to a position where a portion of the valve orifice 12a faces the inner wall of the discharge channel 11a, the inner wall of the discharge channel 11a partially blocks the valve orifice 12a, thereby causing the valve orifice 12a to be partially misaligned with the discharge channel 11a.

[0098] In other embodiments, the regulating valve 12 may also be movably disposed on the first seat 11, that is, the regulating valve 12 may change the flow area of ​​the valve hole 12a connected to the discharge channel 11a by linear movement.

[0099] To facilitate the installation of the regulating valve 12, in one embodiment, referring to Figures 4, 9, and 15, the first seat 11 may be provided with valve mounting channels 11b corresponding to and communicating with the discharge channels 11a. The extending direction of the valve mounting channels 11b intersects the extending direction of the discharge channels 11a. For example, as shown in Figure 9, the extending direction of the valve mounting channels 11b is perpendicular to the extending direction of the discharge channels 11a. In other embodiments, the extending direction of the valve mounting channels 11b may also be oblique to the extending direction of the discharge channels 11a. Each regulating valve 12 is movably installed in its corresponding valve mounting channel 11b, meaning that the regulating valve 12 can move within the valve mounting channel 11b.

[0100] Referring to Figure 9, the valve mounting channel 11b can have a first section 11b1 and a second section 11b2. The first section 11b1 and the second section 11b2 are located on opposite sides of the discharge channel 11a, respectively. A portion of the regulating valve 12 is located within the first section 11b1, and the other portion is located within the second section 11b2. That is, one end of the regulating valve 12 can pass through the discharge channel 11a to move from one side of the discharge channel 11a to the opposite side. This arrangement can improve the stability of the regulating valve 12 installation.

[0101] In other embodiments, the valve mounting channel 11b may only have a first section 11b1 and no second section 11b2, that is, one end of the regulating valve 12 may be located in the discharge channel 11a.

[0102] Please refer to Figures 5, 10, and 13 for the control valve 12, which is manually adjusted. A portion of the control valve 12 extends from the end of the valve mounting channel 11b away from the discharge channel 11a to the outside of the valve mounting channel 11b, forming a force-applying part 12b. The force-applying part 12b is the part of the control valve 12 used to apply external force, so that the control valve 12 can move under the action of external force.

[0103] For example, referring to Figure 10, the force-applying part 12b may be provided with a force-applying component mounting hole 12b1. The extending direction of the force-applying component mounting hole 12b1 intersects with the extending direction of the valve mounting channel 11b. That is, the extending direction of the force-applying component mounting hole 12b1 may be perpendicular to the extending direction of the valve mounting channel 11b or oblique to the extending direction of the valve mounting channel 11b.

[0104] The force-applying component mounting hole 12b1 is used to install a force-applying tool. That is, the operator can insert a part of a screwdriver or other similar force-applying tool into the force-applying component mounting hole 12b1 and then apply force to the force-applying tool so that the force-applying tool can drive the regulating valve 12 to move.

[0105] For example, the force-applying part 12b may also be provided with a force-applying component mounting post. The extending direction of the force-applying component mounting post intersects with the extending direction of the valve mounting channel 11b. That is, the extending direction of the force-applying component mounting post can be perpendicular to the extending direction of the valve mounting channel 11b or oblique to the extending direction of the valve mounting channel 11b. The force-applying component mounting post is used in conjunction with a force-applying tool having a socket. That is, the operator can insert the force-applying component mounting post into the socket of the force-applying tool, and then apply force to the force-applying tool so that the force-applying tool can drive the regulating valve 12 to move.

[0106] For example, referring to Figure 13, for the regulating valve 12 rotatably disposed on the first seat 11, the extrusion die 10 may be equipped with a handwheel 14. The handwheel 14 is detachably anti-rotatingly connected to the force-applying part 12b. That is, the handwheel 14 is not only detachably connected to the force-applying part 12b, but also does not rotate relative to the regulating valve 12. When it is necessary to adjust a certain regulating valve 12, it is only necessary to detachably anti-rotately connect the handwheel 14 to the corresponding regulating valve 12, and then rotate the handwheel 14 so that the handwheel 14 can drive the corresponding regulating valve 12 to rotate relative to the first seat 11 under the action of external force.

[0107] The handwheel 14 shown in Figure 13 is provided with a non-circular hole 14a, which refers to a hole whose cross-sectional shape is not circular. The cross-sectional shape of the non-circular hole 14a shown in Figure 13 is rectangular. In other embodiments, the cross-sectional shape of the non-circular hole 14a can also be semi-circular, elliptical, triangular, etc. The force-applying part 12b is inserted into the non-circular hole 14a to achieve a detachable anti-rotation connection between the handwheel 14 and the force-applying part 12b. That is, the shape of the force-applying part 12b is approximately consistent with the cross-sectional shape of the non-circular hole 14a. For example, the cross-sectional shape of the force-applying part 12b shown in Figure 13 is also rectangular. After the force-applying part 12b is inserted into the non-circular hole 14a, the force-applying part 12b cannot rotate within the non-circular hole 14a. Therefore, by rotating the handwheel 14, the handwheel 14 can drive the corresponding regulating valve 12 to rotate relative to the first seat 11. This configuration facilitates the connection or separation of the handwheel 14 from the force-applying part 12b of each regulating valve 12, thereby improving the convenience of adjustment.

[0108] In other embodiments, the handwheel 14 can also be detachably anti-rotationally connected to the force-applying part 12b by means of threaded connection with the force-applying part 12b, or by fastening the handwheel 14 to the force-applying part 12b with fasteners such as screws and bolts.

[0109] In other embodiments, the extrusion die 10 may not have a handwheel 14. For example, other force-applying tools with similar structure or function to the handwheel 14 may be used instead of the handwheel 14.

[0110] Referring to Figure 8, the outer surface of the regulating valve 12 may also have a sealing groove 12c arranged circumferentially along the regulating valve 12. The extrusion die 10 also includes a sealing ring (not shown in the figure), which is disposed within the sealing groove 12c and makes sealing contact with the inner wall of the valve mounting channel 11b. In other words, the sealing between the regulating valve 12 and the inner wall of the valve mounting channel 11b can be achieved by the sealing ring disposed within the sealing groove 12c, thereby preventing material leakage during the extrusion process.

[0111] The number of sealing grooves 12c can be one or more. When there are multiple sealing grooves 12c, a sealing ring is set in each sealing groove 12c. For example, the outer surface of the regulating valve 12 shown in Figure 8 is provided with two sealing grooves 12c, and a sealing ring is set in each sealing groove 12c.

[0112] Please refer to Figures 8 and 9. For the valve mounting channel 11b with the first section 11b1 and the second section 11b2, sealing grooves 12c can be provided at both the location of the regulating valve 12 in the first section 11b1 and the location of the regulating valve 12 in the second section 11b2. That is, a part of the sealing ring is in sealing contact with the inner wall of the first section 11b1 of the valve mounting channel 11b, and another part of the sealing ring is in sealing contact with the inner wall of the second section 11b2 of the valve mounting channel 11b. Thus, a seal can be formed on both sides of the discharge channel 11a, thereby better preventing material leakage during the extrusion process.

[0113] In one embodiment, referring to Figures 1, 4, 8, 9, 14 and 15, the first seat 11 may be provided with a locking channel 11c that corresponds to and communicates with the valve mounting channel 11b. The extending direction of the locking channel 11c intersects with the extending direction of the valve mounting channel 11b. That is, the extending direction of the locking channel 11c may be perpendicular to the extending direction of the valve mounting channel 11b or oblique to the extending direction of the valve mounting channel 11b.

[0114] The extrusion die 10 includes locking members 13 movably disposed within each locking channel 11c. That is, each locking member 13 corresponds one-to-one with a locking channel 11c, and each locking channel 11c contains a corresponding locking member 13, which can move within its corresponding locking channel 11c. The locking member 13 moves along the extending direction of the locking channel 11c to switch between a locked position abutting against the corresponding regulating valve 12 and an unlocked position avoiding the corresponding regulating valve 12. Specifically, the locking elements 13 in each locking channel 11c are used to lock or unlock the regulating valve 12 in the valve mounting channel 11b corresponding to the locking channel 11c. The movement of the locking element 13 along the extension direction of the locking channel 11c means that the overall movement trend of the locking element 13 is along the extension direction of the locking channel 11c. Based on this, the specific movement mode of the locking element 13 is not limited. For example, the locking element 13 can move along the extension direction of the locking channel 11c by translation or by rotation.

[0115] For example, referring to Figure 8, the locking member 13 can be threadedly engaged with the locking channel 11c. That is, the locking member 13 can move along the extension direction of the locking channel 11c by rotation. At the same time, the locking member 13 can also be kept in the locked position or the unlocked position by utilizing the threaded engagement with the locking channel 11c, without the need for other structures to keep the locking member 13 in the locked position or the unlocked position.

[0116] Please refer to Figure 8. When the locking member 13 abuts against the corresponding regulating valve 12, the part where the locking member 13 abuts against the corresponding regulating valve 12 is actually located in the valve mounting channel 11b. At this time, the locking member 13 is in the locked position, and the locking member 13 locks the regulating valve 12 onto the first seat 11.

[0117] To facilitate the contact between the locking member 13 and the corresponding regulating valve 12, for example, please refer to FIG8, the outer surface of the regulating valve 12 may be provided with a locking groove 12d extending circumferentially along the regulating valve 12. When the locking member 13 is in the locked position, the locking member 13 extends into the locking groove 12d.

[0118] When the locking element 13 avoids the corresponding regulating valve 12, the locking element 13 is in the unlocked position, and the regulating valve 12 can move normally to adjust the opening.

[0119] The locking member 13 can move to either the locked or unlocked position by moving along the extension direction of the locking channel 11c. By locking the regulating valve 12 onto the first seat 11, it is possible to better prevent the position of the regulating valve 12 from shifting and changing the adjusted opening, and it is also possible to better prevent the regulating valve 12 from moving around during the extrusion process and affecting the normal flow of the material, thereby better ensuring that the speed of the material flowing through each discharge channel 11a tends to be consistent.

[0120] In one embodiment, referring to Figures 1 and 5, the regulating valve 12 may be provided with a first indicator mark 12e exposed to the external field of vision, that is, the operator can directly see the first indicator mark 12e with the naked eye. The first indicator mark 12e may be a printed indicator shape (i.e., the indicator shape is a pattern) or an indicator shape formed by part of the structure of the regulating valve 12.

[0121] For example, the shape of the first indicator mark 12e can be a cross shape as shown in Figure 5, or a polygon such as a triangle, quadrilateral, or pentagon, or other shapes that can serve as indicators.

[0122] The position of the first indicator mark 12e changes with the movement of the control valve 12, making it easier for the operator to identify the current position of the control valve 12. For example, the operator can determine whether the control valve 12 is currently in the closed or open position based on the current position of the first indicator mark 12e. If the control valve 12 is in the open position, the operator can also roughly determine the opening degree of the control valve 12 based on the current position of the first indicator mark 12e.

[0123] In another embodiment, referring to FIG13, the regulating valve 12 may also be provided with a second indicator mark 12f exposed to the external view, and the first seat 11 is provided with a first indicator scale 11d exposed to the external view and having multiple marks. The regulating valve 12 is moved so that the second indicator mark 12f points to one of the multiple marks.

[0124] Specifically, each mark represents a different position. For example, the mark can be a combination of one or more of numbers, degrees, and stripes. For instance, the mark shown in Figure 13 is a combination of stripes and degrees.

[0125] The second indicator mark 12f can adopt the same or similar structure as the first indicator mark 12e. For example, the regulating valve 12 shown in FIG13 has a force-applying part 12b. Since the regulating valve 12 is rotatably mounted on the first seat 11 and the cross-sectional shape of the force-applying part 12b is rectangular, the force-applying part 12b can serve as the second indicator mark 12f.

[0126] The regulating valve 12 moves to point the second indicator mark 12f to one of a plurality of marks. For example, the second indicator mark 12f shown in Figure 13 can be referenced by one of the corners of a rectangle, and the mark that corner points to is the mark that the second indicator mark 12f points to.

[0127] The second indicator mark 12f and the first indicator scale 11d work together to make it easier for the operator to identify the current position of the regulating valve 12.

[0128] In another embodiment, the regulating valve 12 may be provided with a second indicator scale exposed to the external view and having multiple markings, and the first seat 11 may be provided with a third indicator mark exposed to the external view. The regulating valve 12 may be moved to make one of the multiple markings point to the third indicator mark.

[0129] The second indicator scale is similar to the first indicator scale 11d, and the third indicator mark is similar to the second indicator mark 12f. The difference is that the second indicator scale is located on the regulating valve 12 instead of the first seat 11, and the third indicator mark is located on the first seat 11 instead of the regulating valve 12. The second indicator scale and the third indicator mark work together to help the operator identify the current position of the regulating valve 12.

[0130] It should be noted that the regulating valve 12 is not limited to adjusting the opening by moving relative to the first seat 11. For example, in some other embodiments, the regulating valve 12 may be provided with a valve body having a valve hole 12a and an openable and closable valve plate. The valve plate moves to change the flow area of ​​the valve hole 12a, thereby adjusting the opening.

[0131] In one embodiment, referring to Figures 13, 16 and 18, the extrusion die 10 may also be provided with a second seat 15 having a flow guide channel 15a. The second seat 15 is located upstream of the first seat 11 along the material flow direction, and the flow guide channel 15a is connected to each discharge channel 11a. That is, the material first flows into the flow guide channel 15a, and then flows to each discharge channel 11a through the flow guide channel 15a.

[0132] Please refer to Figure 16. The flow area of ​​the guide channel 15a gradually increases from the side away from the first base 11 to the side closer to the first base 11. In other words, the closer to the first base 11, the larger the flow area of ​​the guide channel 15a. This makes it easier to introduce the material into each discharge channel 11a more evenly, thereby improving the molding quality of the aerosol matrix 200 extruded from each die core 20.

[0133] In one embodiment, referring to FIG16, the extrusion die 10 may also be provided with a flow divider post 16, which is disposed on the first seat 11, and at least a portion of the flow divider post 16 is located within the flow channel 15a.

[0134] Specifically, the way the diversion guide post 16 is disposed on the first base 11 is not limited. For example, the diversion guide post 16 shown in FIG16 is fastened to the first base 11 by screws. In other embodiments, the diversion guide post 16 can also be welded to the first base 11 or integrally formed.

[0135] The diversion guide post 16 shown in Figure 16 has only a portion of its structure located within the diversion channel 15a. In other embodiments, the entire diversion guide post 16 may be located within the diversion channel 15a.

[0136] Please refer to Figure 16. The external dimensions of the diversion guide post 16 located within the diversion channel 15a gradually expand from the side away from the first base 11 to the side closer to the first base 11. In other words, the closer to the first base 11, the larger the cross-sectional area of ​​the diversion guide post 16. Multiple discharge channels 11a can be arranged around the outer periphery of the diversion guide post 16, which means that the material in the diversion channel 15a is guided by the diversion guide post 16 to be directed to each discharge channel 11a respectively.

[0137] By setting the diversion guide column 16, the pressure of the material in the diversion channel 15a can be more evenly distributed at the inlet of each discharge channel 11a, thereby allowing the material to be more evenly introduced into each discharge channel 11a.

[0138] In one embodiment, please refer to FIG16, the second seat 15 may be provided with a heating fluid channel 15b, which is arranged around the outer periphery of the guide channel 15a.

[0139] The heating fluid channel 15b is used to introduce a fluid with a relatively high temperature. The relatively high temperature fluid can heat the material in the guide channel 15a, thereby further improving the molding quality of the aerosol matrix 200 extruded from each die core 20.

[0140] In one embodiment, referring to Figure 16, the second seat 15 may also be provided with a detection channel 15c communicating with the flow channel 15a. The extrusion die 10 also includes a sensor 17 with a detection head, which extends into the detection channel 15c to detect the pressure and / or temperature within the flow channel 15a. That is, depending on different detection needs, the sensor 17 can be used to detect the pressure within the flow channel 15a, or the temperature within the flow channel 15a, or both pressure and temperature within the flow channel 15a simultaneously. This facilitates monitoring the current state of the material and timely adjustments.

[0141] In one embodiment, please refer to Figures 1 to 3, 14, 15 and 17. Each die core 20 may be detachably disposed at the corresponding discharge channel 11a. When the extrusion die 100 is in the working state, the corresponding die core 20 can be replaced at least by switching the regulating valve 12 from the open state of the discharge channel 11a to the closed state of the discharge channel 11a.

[0142] The extrusion die 100 being in working condition means that the extrusion die 100 is installed on the extruder and is in the state of extruding material.

[0143] In related technologies, during the extrusion process of aerosol generating matrix 200, if one or more die cores on the extrusion die 100 malfunction and need to be replaced, the extruder can only be stopped to replace the die cores. Therefore, this replacement method will greatly reduce the output efficiency of the production line.

[0144] In this embodiment, if one or more of the die cores 20 malfunction while the extrusion die 100 is in operation, the regulating valve 12 corresponding to the malfunctioning die core 20 can be switched from the open state to the closed state to prevent material from flowing to the die core 20. Then, the die core 20 can be replaced, while other normal die cores 20 can continue to extrude the aerosol generating matrix 200. Thus, the die core 20 can be replaced online without stopping the extruder, which can better avoid affecting the output efficiency of the aerosol generating matrix 200 when replacing the die core 20.

[0145] It is understandable that the extrusion die 100 is not limited to changing the die core 20 when it is in operation. The die core 20 can also be changed when the extrusion die 100 is not in operation. However, when the extrusion die 100 is not in operation, the regulating valve 12 can be in the closed state or the open state.

[0146] In one embodiment, referring to Figures 1 to 4 and Figure 6, the outer periphery of each mold core 20 may have a plurality of protruding edges 20a spaced apart. Each discharge channel 11a has a protrusion 11e corresponding to each protruding edge 20a and a first boss 11f located upstream of the protrusion 11e along the material flow direction. All protrusions 11e are spaced apart circumferentially along the discharge channel 11a, and a first clearance opening 11g is formed between adjacent protrusions 11e to allow the protruding edges 20a to pass through. The protruding edges 20a of each mold core 20 are detachably disposed at the corresponding discharge channel 11a by being sandwiched between the first boss 11f and the protrusion 11e within the corresponding discharge channel 11a.

[0147] Specifically, during the installation of the mold core 20, the protruding edges 20a on the mold core 20 are aligned with the corresponding first clearance openings 11g. After the protruding edges 20a pass through the first clearance openings 11g, the mold core 20 is rotated to clamp the protruding edges 20a between the first boss 11f and the corresponding protrusion 11e, thus completing the installation of the mold core 20. When it is necessary to disassemble the mold core 20, simply rotate the mold core 20 in the opposite direction to move the protruding edges 20a to the corresponding first clearance openings 11g, and the mold core 20 can be removed. This method facilitates the installation and removal of the mold core 20, thereby improving the efficiency of mold core 20 replacement.

[0148] It should be noted that if the die core 20 is being replaced while the extrusion die 100 is in operation, the regulating valve 12 should be switched to the closed state during both disassembly and installation of the replaced die core 20. However, during the disassembly of the die core 20, after the protruding edge 20a on the die core 20 moves to the corresponding first clearance opening 11g, the regulating valve 12 can be switched from the closed state to the open state first. This allows the material pressure to push the die core 20 out of the discharge channel 11a. After the die core 20 is pushed out, the regulating valve 12 can be switched from the open state to the closed state, making it easier to remove the die core 20 from the installation channel. After the die core 20 is removed, the operator only needs to remove any remaining material at the installation location of the die core 20, then install the replaced die core 20, and finally switch the regulating valve 12 from the closed state to the open state for normal use of the die core 20. In addition, during the opening process of the regulating valve 12, the opening degree of the regulating valve 12 can be adjusted relatively slowly so that the material slowly fills the discharge channel 11a, thereby ensuring that the molding quality of the aerosol generation matrix 200 initially extruded by the replaced mold core 20 can remain stable.

[0149] In one embodiment, referring to Figures 14, 15, and 17, each die core 20 has an extrusion portion 21 and a limiting portion 22 located on the outer periphery of the extrusion portion 21. A second protrusion 11h is formed on the inner sidewall of each discharge channel 11a. The extrusion die head 10 includes a pressure plate 18 corresponding to each discharge channel 11a and having a second clearance opening 18a. Each pressure plate 18 is detachably connected to the first base 11, such that the limiting portion 22 of each die core 20 is sandwiched between the corresponding pressure plate 18 and the second protrusion 11h, and the extrusion portion 21 of each die core 20 is inserted into the second clearance opening 18a of the corresponding pressure plate 18.

[0150] The way in which the pressure plate 18 is detachably connected to the first seat 11 is not limited. For example, as shown in Figures 14, 15 and 17, the pressure plate 18 is fastened to the first seat 11 by screws. In other embodiments, the pressure plate 18 can also be detachably connected to the first seat 11 by snap-fit ​​or other means.

[0151] The extrusion section 21 of the core 20 is the part that extrudes the material to form the aerosol generation matrix 200.

[0152] Specifically, during the installation of the mold core 20, the limiting part 22 of the mold core 20 is first placed against the second protrusion 11h in the corresponding discharge channel 11a. Then, the extrusion part 21 of the mold core 20 is inserted into the second clearance opening 18a of the corresponding pressure plate 18. Next, the pressure plate 18 is connected to the first base 11, thus completing the installation of the mold core 20. When it is necessary to disassemble the mold core 20, simply separate the pressure plate 18 from the first base 11 to remove the mold core 20. This method also facilitates the disassembly and assembly of the mold core 20, thereby improving the efficiency of mold core 20 replacement.

[0153] In addition, the replacement method of this type of die core 20 when the extrusion die 100 is in working condition is similar to the replacement method of the die core 20 described in the previous embodiment. During the disassembly of the die core 20, after separating the pressure plate 18 from the first seat 11, the regulating valve 12 can be switched from the closed state to the open state first, so as to use the pressure of the material to push the die core 20 out of the discharge channel 11a. After the die core 20 is pushed out, the regulating valve 12 is switched from the open state to the closed state, which also makes it easier to remove the die core 20 from the installation channel.

[0154] It should be noted that the way in which the mold core 20 is detachably set at the corresponding discharge channel 11a is not limited to the way described in the above embodiments. For example, in some other embodiments, the mold core 20 can be threaded into the discharge channel 11a, or the mold core 20 can also be fastened to the first base 11 by fasteners such as screws and bolts, as long as the mold core 20 can be disassembled and assembled.
