DETAILED DESCRIPTION

[0027] The present application will be further described in detail through specific embodiments in combination with the drawings. In different embodiments, similar elements are denoted by associated similar element reference numbers. In the following embodiments, many details are described in order to make the present application better understood. However, those skilled in the art can easily recognize that, in different cases, some features can be omitted, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and it is not necessary for those skilled in the art to understand the related operations in detail according to the description in the specification and the general technical knowledge in the art.

[0028] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0029] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0030] In related technologies, the size of the discharge baffle at the outlet can be reduced so that it does not contact the feed tray, thus preventing friction and wear that could cause metal debris to fall off. However, this method causes particles to fall into the gap between the feed tray and the discharge baffle, accumulating on the feed tray. Over time, this accumulation makes the feed tray difficult to clean, and even worse, particles squeezed into the gap can cause wear on the feed tray, leading to equipment aging and a shortened service life.

[0031] To address the aforementioned issues, this application provides a granulation device in which a flexible wear-resistant component is installed between the baffle plate and the turntable and receiving sleeve. This prevents the baffle plate from directly contacting the turntable and receiving sleeve and causing friction, thus preventing metal fragments from falling into the granular material and improving the quality of the granular material. Furthermore, it prevents particles from falling into the gap between the baffle plate and the turntable and receiving sleeve and causing wear on the equipment, thereby preventing equipment aging and extending the service life of the equipment.

[0032] In the following embodiments, the granulated material produced by the granulation device may be, for example, a non-combustible granular atomizing matrix (granular smoke-generating matrix). Of course, the granular material may also be food granules or pharmaceutical granules, etc.

[0033] See Figure 1 and Figure 2 As shown, the pelletizing apparatus provided in this application includes a turntable 10, a forming barrel 20, an extrusion assembly 30, a receiving sleeve 40, multiple cutting mechanisms 50, and a material blocking assembly 60.

[0034] The turntable 10 can rotate around its own axis. Driven by the first rotation drive mechanism, the turntable 10 rotates around its own axis to fix the forming barrel 20 on the turntable 10. The forming barrel 20 can rotate synchronously with the turntable 10. The forming barrel 20 is a barrel-shaped structure with one end closed and the other end having a feed port 22. The closed end of the forming barrel 20 is fixed on the turntable 10.

[0035] The axis of the forming barrel 20 of the barrel structure coincides with the axis of the rotary disc 10, so that the rotary disc 10 and the forming barrel 20 rotate coaxially.

[0036] The forming barrel 20 is used to contain material, which can enter the interior of the forming barrel 20 through the material inlet 22 of the forming barrel 20, wherein the material can be raw material for making atomization substrate, or raw material for making food particles or medicine particles. A plurality of forming holes 21 are arranged on the side wall of the forming barrel 20, and the plurality of forming holes 21 are circumferentially divided and arranged on the side wall of the forming barrel 20 in a manner of surrounding the axis of the forming barrel 20.

[0037] The material is the material for making atomization substrate, which can generate aerosol in a heat-not-burn manner, for example, can be a smoking substrate with glycerol and propylene glycol as main components. Of course, in other embodiments, the material can also be other components such as medicine, food, and the like.

[0038] The extrusion assembly 30 is arranged in the interior of the forming barrel 20 and can rotate relative to the forming barrel 20. The extrusion assembly 30 is used to extrude the material from the forming holes 21 to form columnar material when rotating relative to the forming barrel 20. The extrusion assembly 30 is arranged in the interior of the forming barrel 20 in a manner of being rotatable relative to the forming barrel 20, and the extrusion assembly 30 can push the material to the side wall of the forming barrel 20 when rotating relative to the forming barrel 20, so that the material is extruded from the forming holes 21 to form columnar material.

[0039] It should be noted that the extrusion assembly 30 can be driven by the second rotation driving mechanism, and the rotation direction of the extrusion assembly 30 is the same as or not the same as that of the rotary disc 10, in other words, the extrusion assembly 30 can rotate in the same direction as or not the same direction as the forming barrel 20. When the extrusion assembly 30 rotates in the same direction as the forming barrel 20, the relative rotation speed exists between the two, that is, the material can be pushed to the side wall of the forming barrel 20 by the extrusion assembly 30, and at the same time, the material can be extruded from the forming holes 21. When the extrusion assembly 30 rotates in the same direction as the forming barrel 20, the rotation speeds of the two need to be kept different, for example, the rotation speed of the extrusion assembly 30 is greater than that of the forming barrel 20, so that the extrusion assembly 30 rotates relative to the forming barrel 20, and the material can be pushed to the side wall of the forming barrel 20 by the extrusion assembly 30 and extruded from the forming holes 21.

[0040] Referring to Figure 1 and Figure 2As shown, the extrusion assembly 30 includes an extrusion knife 31, which can be arranged inside the forming barrel 20 in a manner of rotating around the axis of the forming barrel 20 under the driving of the second rotary driving mechanism, wherein the extrusion knife 31 has a preset gap with the inner side wall of the forming barrel 21 at one end thereof towards the inner side wall of the forming barrel 20, and the material can be pushed into the preset gap in the process of rotation of the extrusion knife 31, and the material is extruded from the forming hole 21 by the extrusion force provided by the extrusion knife 31.

[0041] The radial size of the rotating disc 10 is greater than the radial size of the forming barrel 20, and the receiving sleeve 40 is sleeved on the circumferential side of the rotating disc 10 in the radial direction, so that the receiving sleeve 40 is spaced from the outer side wall of the forming barrel 20 to form the material storage space 11.

[0042] The receiving sleeve 40 is sleeved on the circumferential side of the rotating disc 10, more specifically, the receiving sleeve 40 is sleeved on the outer circumferential side of the rotating disc 10. Among them, the receiving sleeve 40 is kept in a stationary state relative to the rotating disc 10, the inner side wall of the receiving sleeve 40 and the outer side wall of the forming barrel 20 correspond to two opposite side walls of the material storage space 11, and the rotating disc 10 corresponds to the bottom wall of the material storage space 11, that is, the material storage space 11 in the form of a groove is enclosed by the inner side wall of the receiving sleeve 40, the outer side wall of the forming barrel 20 and the rotating disc 10.

[0043] A plurality of cutting mechanisms 50 are arranged on the periphery of the forming barrel 20, wherein the cutting mechanism 50 includes a cutting piece 51, the cutting piece 51 is installed between the receiving sleeve 40 and the outer side wall of the forming barrel 20, and the cutting piece 51 in each cutting mechanism 50 is arranged on the periphery of the forming barrel 20 in a manner of surrounding the axis of the forming barrel 20, wherein the cutting piece 51 is used to cut the columnar material molded by the extrusion assembly 30 from the forming hole 21 into granular material.

[0044] In this embodiment, the granular material molded by the cutting piece 51 can be temporarily stored in the material storage space 11. In some embodiments, a discharge port 41 is formed on the receiving sleeve 40 and communicates with the material storage space 11, so as to discharge the granular material temporarily stored in the material storage space 11 for collection.

[0045] In the process of rotation of the forming barrel 20 under the action of the rotating disc 10, the cutting piece 51 remains stationary relative to the forming barrel 20, and with the rotation of the forming barrel 20, the columnar material molded by the extrusion assembly 30 from the forming hole 21 is cut by the cutting piece 51 into granular material.

[0046] The size of the granular material can be adjusted according to the rotating speed of the forming barrel 20. With the increase of the rotating speed of the forming barrel 20, the time for the cutting member 51 to contact the columnar material is shortened, and the size of the granular material cut by the cutting member 51 is reduced accordingly. Correspondingly, with the decrease of the rotating speed of the forming barrel 20, the time for the cutting member 51 to contact the columnar material is increased, and the size of the granular material cut by the cutting member 51 is increased accordingly.

[0047] Of course, when the rotating speed of the forming barrel 20 remains unchanged, the size of the granular material can also be adjusted by adjusting the distance between the cutting member 51 and the outer side wall of the forming barrel 20. For example, the distance between the cutting member 51 and the outer side wall of the forming barrel 20 is increased to increase the size of the granular material, and the distance between the cutting member 51 and the outer side wall of the forming barrel 20 is reduced to reduce the size of the granular material.

[0048] As shown in Figures 1-4 , the material blocking assembly 60 includes a material blocking member 61 and a flexible wear-resistant member 62. The material blocking member 61 is arranged on the cutting member 51 near the discharge port 41, and is used to guide the granular material formed after being cut by the cutting member 51 to the discharge port 41, so that the granular material is discharged from the discharge port 41 and collected. The flexible wear-resistant member 62 is arranged on the material blocking member 61. The material blocking member 61 has one side facing the rotating disc 10 and one side facing the receiving sleeve 40. The flexible wear-resistant member 62 seals the one side of the material blocking member 61 facing the rotating disc 10 and the one side of the material blocking member 61 facing the receiving sleeve 40 by abutting against the rotating disc 10 and the receiving sleeve 40, thereby avoiding direct contact between the material blocking member 61 and the rotating disc 10 and the receiving sleeve 40.

[0049] The material blocking member 61 is a plate-shaped structure usually made of metal material, which can ensure the structural strength of the material blocking member 61. The flexible wear-resistant member 62 can avoid direct contact between the material blocking member 61 and the rotating disc 10 and the receiving sleeve 40, and seal the one side of the material blocking member 61 facing the rotating disc 10 and the one side of the material blocking member 61 facing the receiving sleeve 40 by abutting against the rotating disc 10 and the receiving sleeve 40, thereby avoiding the granular material entering the gap between the material blocking member 61 and the rotating disc 10 and the receiving sleeve 40, so that the rotating disc 10 can be kept clean for a long time, reducing the labor and time cost of cleaning, and also avoiding the wear of the rotating disc 10 and the receiving sleeve 40 caused by the material accumulated in the gap for a long time, further preventing the aging of the granulating device and prolonging the service life of the granulating device.

[0050] Usually, a box-shaped collecting device is arranged outside the discharge port 41 to collect the granular material discharged from the discharge port 41. In order to facilitate the granular material to be discharged from the discharge port 41 and collected by the collecting device, the flexible wear-resistant member 62 is arranged on the material blocking member 61. Figure 1 and Figure 2As shown, a discharge chute 70 is further installed at the discharge port 41, and a box-shaped collecting device is usually arranged below the discharge chute 70, and the discharge chute 70 can guide the direction of the discharge of the granular material, and the granular material falls into the collecting device under the action of gravity and is collected.

[0051] Continuing to refer to Figure 1 and Figure 2 As shown, the flexible wear-resistant part 62 is arranged at the side of the material blocking part 61 facing the rotating direction of the rotating disc 10, and in combination with Figure 3 As shown, the flexible wear-resistant part 62 extends out of the side of the material blocking part 61 facing the rotating disc 10 and the side of the material blocking part 61 facing the receiving sleeve 40, so that under the action of the rotating of the rotating disc 10, the part of the flexible wear-resistant part 62 extending out of the side of the material blocking part 61 facing the rotating disc 10 is located between the material blocking part 61 and the rotating disc 10, and the part of the flexible wear-resistant part 62 extending out of the side of the material blocking part 61 facing the receiving sleeve 40 is located between the material blocking part 61 and the receiving sleeve 40, so that the material blocking part 61 can avoid directly contacting the rotating disc 10 and the receiving sleeve 40, thereby avoiding the problem that the rotating of the rotating disc 10 directly rubs against the material blocking part 61 to generate debris, and further improving the quality of the granular material.

[0052] Continuing to refer to Figure 3 As shown, the length of the flexible wear-resistant part 62 extending out of the side of the material blocking part 61 facing the rotating disc 10 is greater than the distance between the side of the material blocking part 61 facing the rotating disc 10 and the rotating disc 10, and the length of the flexible wear-resistant part 62 extending out of the side of the material blocking part 61 facing the receiving sleeve 40 is greater than the distance between the side of the material blocking part 61 facing the receiving sleeve 40 and the receiving sleeve 40, in other words, the size of the material blocking part 61 is reduced, so that the material blocking part 61 does not directly contact the rotating disc 10 and the receiving sleeve 40, and under the action of the friction between the rotating of the rotating disc 10 and the flexible wear-resistant part 62, the part of the flexible wear-resistant part 62 extending out of the side of the material blocking part 61 facing the rotating disc 10 and the part of the flexible wear-resistant part 62 extending out of the side of the material blocking part 61 facing the receiving sleeve 40 are driven to the side of the material blocking part 61 facing the rotating disc 10 and the rotating disc 10 and the side of the material blocking part 61 facing the receiving sleeve 40 and the receiving sleeve 40, respectively.

[0053] Referring to Figure 4 As shown, the flexible wear-resistant part 62 is arranged at the side of the material blocking part 61 facing the rotating disc 10 and the side of the material blocking part 61 facing the receiving sleeve 40, and such arrangement can save the manufacturing cost of the flexible wear-resistant part 62, and the flexible wear-resistant part 62 is arranged only between the side of the material blocking part 61 facing the rotating disc 10 and the rotating disc 10 and between the side of the material blocking part 61 facing the receiving sleeve 40 and the receiving sleeve 40.

[0054] The flexible wear-resistant piece 62 is made of silica gel material, which can produce elastic deformation when abutting against the rotary disc 10 and the receiving sleeve 40, so as to achieve the sealing effect. When the material is food-grade material, the flexible wear-resistant piece 62 is made of food-grade silica gel material.

[0055] As shown in Figure 3 and Figure 4 , the flexible wear-resistant piece 62 is detachably mounted on the material blocking piece 61. The flexible wear-resistant piece 61 will be worn out after a long time of use due to the contact with the rotary disc 10 and the receiving sleeve 40, therefore, the detachable connection mode facilitates the replacement of the flexible wear-resistant piece 61 which is worn out and affects the use effect.

[0056] As shown in Figure 3 , the flexible wear-resistant piece 62 is in a plate-shaped structure, and the part of the flexible wear-resistant piece 62 which does not extend out of the material blocking piece 61 is fixed on the material blocking piece 61 by the bolt 63. As shown in Figure 4 , the flexible wear-resistant piece 62 is detachably mounted only on the side of the material blocking piece 61 facing the rotary disc 10 and the side of the material blocking piece 61 facing the receiving sleeve 40.

[0057] In order to facilitate the guiding of the granular material to the discharge port 41, the material blocking piece 61 is bent, and one end of the material blocking piece 61 faces the outer side wall of the forming barrel 20, and the other end of the material blocking piece 61 extends to the discharge port 41, thereby guiding the granular material to the discharge port 41.

[0058] As shown in Figures 1-4 , the cutting mechanism 50 further comprises a connecting piece 52, one end of the connecting piece 52 is connected to the receiving sleeve 40, and the cutting piece 51 is arranged at the other end of the connecting piece 52. As shown in Figure 1 and Figure 2 , the free end of the cutting piece 51 abuts against the outer side wall of the forming barrel 20, and the free end of the cutting piece 51 is inclinedly arranged towards the downstream of the rotation direction of the forming barrel 20, so that the free end of the cutting piece 51 can cut the columnar material into granular material. The free end of the cutting piece 51 is the end of the cutting piece 51 facing the forming barrel 20, and the free end is inclinedly arranged towards the downstream of the rotation direction of the forming barrel 20, so that the free end of the cutting piece 51 abuts against the outer side wall of the forming barrel 20, and the cutting piece 51 can generate a cutting force on the columnar material extruded from the forming hole 21 under the action of the rotating forming barrel 20.

[0059] In this embodiment, the connecting piece 52 and the cutting piece 51 arranged at the other end of the connecting piece 52 are in an integrated structure, and the integrated structure is inclinedly arranged towards the downstream of the rotation direction of the forming barrel 20.

[0060] As shown in Figure 1 , the cutting mechanism 50 further comprises an elastic reset piece 53, Figure 1Only a schematic diagram in which the elastic reset member 53 is arranged on one cutting mechanism 50 is shown, one end of the elastic reset member 53 is connected to the connecting member 52, and the other end of the elastic reset member 53 is connected to the receiving sleeve 40, the elastic potential energy provided by the elastic reset member 53 generates a pulling force on the connecting member 52 and the cutting member 51 of the integral structure, and then the free end of the cutting member 51 is attached to the outer side wall of the forming barrel 20.

[0061] Referring to Figure 3 and Figure 4 As shown, the free end of the cutting member 51 has an attachment surface 511 and a cutting blade part 512, wherein the attachment surface 511 is located on the side of the cutting member 51 facing the forming barrel 20, and the cutting blade part 512 is located at the end of the end of the cutting member 51 away from the connecting member 52, the attachment surface 511 is circumscribed on the outer side wall of the forming barrel 20, and the cutting blade part 512 can cut the columnar material into granular material.

[0062] Specifically, one end of the connecting member 52 is rotatably mounted on the receiving sleeve 40, and under the action of the elastic deformation of the elastic reset member 53, the other end of the connecting member 52 can be pulled towards the direction of the outer side wall of the forming barrel 20, so that the attachment surface 511 is circumscribed on the outer side wall of the forming barrel 20, so as to cooperate with the rotating forming barrel 20 to cut the columnar material extruded from the forming hole 41 into granular material by the cutting blade part 512.

[0063] In summary, in the granulating device provided by the present application, the flexible wear-resistant member 62 is arranged to avoid direct contact of the material blocking member 61 with the rotating disc 10 and the receiving sleeve 40, and the flexible wear-resistant member 62 abuts against the rotating disc 10 and the receiving sleeve 40 to seal the side of the material blocking member 61 facing the rotating disc 10 and the side of the material blocking member 61 facing the receiving sleeve 40, so as to prevent the granular material from entering the gap between the material blocking member 61 and the rotating disc 10 and the receiving sleeve 40, so that the rotating disc 10 can be kept clean for a long time, reducing the labor and time cost during cleaning, and also avoiding the wear of the rotating disc 10 and the receiving sleeve 40 caused by the material accumulated in the gap for a long time, further preventing the aging of the granulating device and prolonging the service life of the granulating device.
