Description

Technical Field

[0001] This invention relates to the field of popping bead production technology, specifically to a popping bead surface curing and molding system based on ultraviolet light source curing, used for popping bead surface curing and molding. Background Technology

[0002] Capsule flavorings, also known as flavor capsules, brittle capsules, or beads, come in various sizes, generally between 2.6 and 4.6 mm in diameter. They are poppable beads that release a bursting sensation when squeezed. They are primarily used in cigarette filters, commonly known as menthol capsule cigarettes. Capsule production equipment includes a titration system, a forming system, a filtration system, a cleaning and curing system, a filling and sealing system, a sterilization system, and a PLC central control system. The forming system is mainly used for curing and shaping the surface of the capsules.

[0003] In recent years, in addition to traditional heat curing, cooling curing, and curing liquid curing, ultraviolet (UV) light source curing technology has been gradually designed into the curing methods of burst bead molding systems. UV curing refers to the process of using UV light to initiate the formation of excited-state molecules under UV irradiation, utilizing the photosensitive properties of photoinitiators. These molecules then decompose into free radicals or ions, leading to the polymerization and cross-linking of small unsaturated organic molecules, thus achieving the UV curing process. For example, the Chinese invention patent CN110280197B, which discloses "A Multi-Layer UV-Curable Bursting Bead Production Equipment," consists of a feeding system A, a molding system B, a circulation system C, and a control system D. The molding system B comprises a shear cup 10, a molding riser 11, a left UV curing lamp 21, a right UV curing lamp 22, a cylindrical UV curing lamp 14, a first lifting motor and its matching screw 12, a molding coil 13, and a discharge pipe 16. Clearly, the aforementioned burst bead production equipment uses UV curing technology. However, as can be seen from the technical content disclosed in the patent, the left UV curing lamp 21 and the right UV curing lamp 22 are symmetrically arranged on both sides of the forming riser 11. This structure can only irradiate the two sides of the forming riser 11 facing the UV curing lamp. The illumination is limited and cannot irradiate the forming riser 11 in all directions. As a result, the irradiation of the surface of the bursting beads by ultraviolet light is not ideal, and it is difficult to achieve a stable high focus and comprehensive irradiation effect. The production efficiency of bursting beads is low. Therefore, it is necessary to propose a new bursting bead surface curing and forming system. Summary of the Invention

[0004] The purpose of this invention is to provide a surface curing and molding system for popping beads based on ultraviolet light source curing, so as to solve the technical problem that existing ultraviolet light source molding devices are difficult to achieve stable high focusing and comprehensive irradiation effects.

[0005] To achieve the above-mentioned technical objectives, this invention provides a surface curing and molding system for popping beads based on ultraviolet light source curing, comprising a pre-curing device and a secondary curing device arranged sequentially according to the curing process, wherein:

[0006] The pre-curing device includes a first housing assembly, a first reflective assembly, and a first light source assembly. The first reflective assembly includes two first reflective units, which are respectively disposed on the front and rear inner surfaces of the first housing assembly, and the first reflective unit disposed on the front surface is detachably connected to the first housing assembly.

[0007] The first light source assembly includes two first lamp body units, which are respectively disposed on the two inner sides of the first housing assembly. The two first reflective units and the two first lamp body units are connected in an alternating manner to form a cylindrical first receiving cavity for accommodating the central tube of the sinking tube.

[0008] The secondary curing device includes a second housing assembly, a second reflector assembly, and a second light source assembly. The second light source assembly includes three second lamp units, which are respectively disposed on three inner surfaces of the second housing assembly at 120° angles along the axial direction.

[0009] The second reflective assembly includes three second reflective units fixed to the bottom surface of the second housing assembly, and each second reflective unit is located directly opposite each second lamp body unit. The three second lamp body units and the three second reflective units are staggered to form a cylindrical second receiving cavity for accommodating the central tube of the settling pipe. The second receiving cavity is coaxial with the first receiving cavity.

[0010] Furthermore, the first housing assembly includes a first housing body, a first upper cover, and a first lower cover. The first upper cover and the first lower cover are respectively installed at the upper and lower openings of the first housing body. One side of the first housing body is provided with an opening for detachably connecting the first reflective unit.

[0011] Furthermore, each of the first reflective units includes a first reflector and a first fixing bracket for fixing the first reflector. The two sides of the first fixing bracket are detachably connected to the two ends of the opening. The first reflector has an arc-shaped reflective surface for reflecting the light emitted by the first lamp unit.

[0012] Furthermore, each of the first lamp body units includes a first light source cover plate, a first lens, a first COB light-emitting module, and a first heat sink. The first light source cover plate, the first COB light-emitting module, and the first heat sink are installed sequentially from the central tube of the sinking tube to the side of the first housing assembly. The first lens is installed in a groove on the side of the first light source cover plate near the central tube of the sinking tube.

[0013] Furthermore, the second housing assembly has a regular hexagonal cross-section and is composed of a second housing body, a second upper cover, and a second lower cover. The second upper cover and the second lower cover are respectively installed at the upper and lower openings of the second housing body.

[0014] Furthermore, the second outer shell body includes a second front outer shell body and a second rear outer shell body. One end of the second front outer shell body is hinged to one end of the second rear outer shell body, and the other end of the second front outer shell body is snapped into the other end of the second rear outer shell body. The second front outer shell body is provided with a handle for easy opening.

[0015] Furthermore, each of the second reflective units includes a second reflector and a second fixing bracket for fixing the second reflector. The second fixing bracket is mounted on the upper surface of the second lower cover, and the second reflector has an arc-shaped reflective surface for reflecting the light emitted by the second lamp unit.

[0016] Furthermore, each of the second lamp body units includes a second light source cover plate, a second lens, a second COB light-emitting module, and a second heat sink. The second light source cover plate, the second COB light-emitting module, and the second heat sink are installed sequentially from the center tube of the sinking tube to the side of the second housing assembly. The second lens is installed on the side of the second light source cover plate near the center tube of the sinking tube, and the second lens is a semi-cylindrical lens.

[0017] Furthermore, the pre-curing device also includes a first fan assembly disposed on the side of each of the two first lamp body units away from the central tube of the settling pipe, the first fan assembly consisting of a fan frame and a fan cover.

[0018] Furthermore, the secondary curing device also includes second fan assemblies respectively disposed on the side of the three second lamp units away from the central tube of the settling tube, and the second fan assemblies have the same structure as the first fan assemblies.

[0019] Compared with the prior art, the beneficial effects of the present invention mainly include:

[0020] This invention provides a UV-based surface curing system for popping beads. By sequentially passing a central tube of a settling tube through a pre-curing device and a secondary curing device, the popping beads in the central tube are irradiated by first lamp units positioned on both sides of the central tube during the pre-curing process. Two first reflective units ensure uniform light distribution to the surface of the popping beads, resulting in highly focused and comprehensive irradiation, which is beneficial for bead formation. The formed popping beads then pass through the secondary curing device. A second lamp unit is positioned at 120° intervals along the axis of the central tube, and a second reflective unit directly in front of each second lamp unit ensures uniform light distribution to the surface of the popping beads, resulting in highly focused and comprehensive irradiation, which is beneficial for further curing. In summary, this UV-based surface curing system for popping beads effectively cures the beads during production, leading to a steady increase in production efficiency. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] Please see Figure 1 , Figure 2 As shown, this invention provides a surface curing and molding system for popping beads based on ultraviolet light source curing. This curing and molding system is installed on a popping bead production equipment 400 and includes a pre-curing device 100 and a secondary curing device 200. A settling tube center tube 300 passes sequentially through the pre-curing device 100 and the secondary curing device 200. The pre-curing device 100 is assembled with the popping bead production equipment 400 through four threaded holes on its back side, and the secondary curing device 200 is assembled with the popping bead production equipment 400 through three threaded holes on its bottom side. The curing process is as follows: Figure 3As shown, the droplet system of the bursting bead production equipment 400 drips the fragrance mixture into the central tube 300 of the settling tube at a certain speed. Since the fragrance mixture and water are immiscible, when the fragrance mixture passes through the pre-curing device 100, the ultraviolet light source of the pre-curing device irradiates its surface, quickly forming a brittle shell, gradually forming bursting bead particles (at this time, the brittle shell on the surface of the bursting bead is relatively soft; this curing step is only to separate the fragrance mixture and produce bursting bead particles). The bursting bead continues to move downwards and passes through the secondary curing device 200, where the brittle shell is cured again, forming bursting beads with a certain surface hardness. It should be noted that the settling tube and the central tube 300 are always filled with water, which is beneficial for the separation of bursting beads and water during the bursting bead forming process. Furthermore, after the bursting beads are formed, they can sink to the receiving cavity at a certain speed using the buoyancy of the water.

[0037] Among them, such as Figure 4 , Figure 5 As shown, the pre-curing device 100 includes a first housing assembly 110, a first reflective assembly 120, and a first light source assembly 130. The first reflective assembly 120 includes two first reflective units 121, which are respectively disposed on the front and rear inner sides of the first housing assembly 110. The first reflective unit 121 disposed on the front side is detachably connected to the first housing assembly 110. The first light source assembly 130 includes two first lamp units 131, which are respectively disposed on the left and right inner sides of the first housing assembly 110. The two first reflective units 121 and the two first lamp units 131 are alternately connected to form a cylindrical first receiving cavity 140 for accommodating the central tube 300 of the settling tube.

[0038] like Figure 7 , Figure 8 As shown, the secondary curing device 200 includes a second outer shell assembly 210, a second reflector assembly 220, and a second light source assembly 230. The second light source assembly 230 includes three second lamp body units 231, which are respectively disposed on three inner side surfaces of the second outer shell assembly 210 at 120° along the axial direction. The second reflector assembly 220 includes three second reflector units 221 fixed to the inner bottom surface of the second outer shell assembly 210, and each second reflector unit 221 is disposed directly opposite each second lamp body unit 231. The three second lamp body units 231 and the three second reflector units 221 are staggered to form a cylindrical second receiving cavity 240 for accommodating the central tube 300 of the settling tube. The second receiving cavity 240 is coaxial with the first receiving cavity 140.

[0039] In use, when the popping droplets in the central tube 300 of the settling tube pass through the pre-curing device 100, the first lamp units 131 set on both sides of the central tube 300 of the settling tube irradiate each other, and the light is evenly irradiated onto the surface of the popping droplets through two first reflective units 121, so that the surface of the popping droplets can receive a highly focused and comprehensive irradiation effect, which is conducive to the formation of popping droplets. After the formed popping droplets pass through the secondary curing device 200, a second lamp unit 231 is set at 120° on each side of the central tube 300 of the settling tube 200, and the light emitted by the second lamp unit 231 is evenly irradiated onto the surface of the popping droplets through the second reflective unit 221 directly in front of each second lamp unit 231, so that the surface of the popping droplets can receive a highly focused and comprehensive irradiation effect, which is conducive to the further curing of the surface of the popping droplets.

[0040] Specifically, each component of the pre-curing device 100 described above will be described in detail. Please refer to [link / reference]. Figure 5 As shown, the first housing assembly 110 includes a first housing body 111, a first upper cover 112, and a first lower cover 113. The first housing body 111 is a cuboid frame with open top and bottom. The first upper cover 112 and the first lower cover 113 are respectively installed at the two open openings. One side of the first housing body 111 is provided with an opening for detachably connecting the first reflective unit 121. In this embodiment, the opening side is the front of the first housing assembly 110, and the side opposite to it is the rear side. The two sides between the front and the rear are the left and right sides, respectively. The first reflective unit 121 is located at the front of the first housing assembly 110. A threaded hole for assembly with the burst bead production equipment 400 is opened at the rear. Two mounting holes for installing the first fan assembly 150 are opened at the top and bottom on the left and right sides.

[0041] In this embodiment, the first reflective assembly 120 consists of two identical and mirror-image first reflective units 121. Each first reflective unit 121 includes a first reflector plate 1211 and a first fixing bracket 1212 for fixing the first reflector plate 1211. The two sides of the first fixing bracket 1212 are detachably connected to the two ends of the opening of the first housing body 111 so as to place the sinking tube center tube 300 into the first receiving cavity 140. The first reflector plate 1211 has an arc-shaped reflective surface for reflecting the light emitted by the first lamp body unit 121. The arc-shaped reflective surface allows light to be evenly irradiated onto the surface of the popping beads to be pre-cured, which is beneficial to the formation of popping beads.

[0042] Optionally, the first reflector 1211 is made of mirrored aluminum plate.

[0043] In this embodiment, the first light source assembly 130 consists of two identical, mirror-arranged first lamp body units 131. Each first lamp body unit 131 includes a first light source cover plate 1311, a first lens 1312, a first COB light-emitting module 1313, and a first heat sink 1314. The first light source cover plate 1311, the first COB light-emitting module 1313, and the first heat sink 1314 are installed sequentially from the central tube 300 of the settling tube to the side of the first housing assembly 110. The first lens 1312 is installed in the groove on the side of the first light source cover plate 1311 near the central tube 300 of the settling tube. The two first lenses 1312 can effectively concentrate the ultraviolet light emitted by the first COB light-emitting module 1313, prevent light diffusion, and greatly improve the curing efficiency.

[0044] In this embodiment, the pre-curing device 100 further includes a first fan assembly 150 respectively disposed on the side of the two first lamp body units 131 away from the central tube 300 of the settling tube. The first fan assembly 150 consists of a fan frame 151 and a fan cover 152. The fan frame 151 is mounted on the first heat sink 1314. The fan of the fan frame 151 is located in the mounting holes on the left and right sides of the first outer shell body 111. The fan cover 152 covers the fan.

[0045] The airflow direction of the heat dissipation of the pre-curing device 100 is as follows: Figure 6 As shown, when the ultraviolet light source provided by the first light source assembly 130 is in use, the mounting holes located on the lower left and right sides of the first housing body 111 are air inlets, while the mounting holes located on the upper left and right sides of the first housing body 111 are air outlets, resulting in good heat dissipation.

[0046] Specifically, each component of the aforementioned secondary curing apparatus 200 will be described in detail. Please refer to [link / reference]. Figure 8 As shown, the cross-section of the second housing assembly 210 is a regular hexagon, and it consists of a second housing body 211, a second upper cover 212 and a second lower cover 213. The second upper cover 212 and the second lower cover 213 are respectively installed at the upper and lower openings of the second housing body 211.

[0047] In this embodiment, the second outer shell body 211 includes a second front outer shell body 2111 and a second rear outer shell body 2112. One end of the second front outer shell body 2111 is hinged to one end of the second rear outer shell body 2112 via a hinge. The other end of the second front outer shell body 2111 is snapped to the other end of the second rear outer shell body 2112 via a buckle. The second front outer shell body 2111 is provided with a handle for easy opening. The handle allows the second front outer shell body 2111 and the second rear outer shell body 2112 to be opened so that the submerged tube center tube 300 can be placed into the second receiving cavity 240.

[0048] Optionally, the second front housing body 2111 and the second rear housing body 2112 are also provided with mounting holes for mounting the second fan assembly 250.

[0049] In this embodiment, the second reflective assembly 220 consists of three second reflective units 221 evenly arranged around the center tube 300 of the settling tube. Each second reflective unit 221 includes a second reflector 2211 and a second fixing bracket 2212 for fixing the second reflector 2211. The second fixing bracket 2212 is installed on the upper surface of the second lower cover 213. The second reflector 2211 has an arc-shaped reflective surface for reflecting the light emitted by the second lamp unit 231. The arc-shaped reflective surface allows light to be evenly irradiated onto the surface of the popping beads that are about to be pre-cured, which is beneficial to the formation of popping beads.

[0050] Optionally, the second reflector 2211 is also made of mirrored aluminum plate.

[0051] It is understandable that the curvature of the first reflector 1211 and the second reflector 2211 is not limited, and can be set according to the reflection requirements in actual use.

[0052] In this embodiment, the second light-emitting component 230 is composed of three second lamp body units 231. Each second lamp body unit 231 includes a second light source cover plate 2311, a second lens 2312, a second COB light-emitting module 2313, and a second heat sink 2314. The second light source cover plate 2311, the second COB light-emitting module 2313, and the second heat sink 2314 are installed sequentially from the central tube 300 of the settling tube to the side of the second housing component 210. The second lens 2312 is installed on the side of the second light source cover plate 2311 near the central tube 300 of the settling tube, and the second lens 2312 is a semi-cylindrical lens. The first lens 1312 of the two semi-cylindrical lenses can more effectively concentrate the ultraviolet light emitted by the first COB light-emitting module 1313 and prevent light diffusion. The light-concentrating effect is better than that of a cylindrical lens. Therefore, a semi-cylindrical lens is used in the secondary curing device 200.

[0053] In this embodiment, the secondary curing device 200 further includes a second fan assembly 250 disposed on the side of the two second lamp body units 231 away from the central tube 300 of the settling tube. The second fan assembly 250 has the same structure as the first fan assembly 150.

[0054] The heat dissipation airflow direction of the secondary curing device 200 is as follows: Figure 9As shown, when the ultraviolet light source provided by the second light source assembly 230 is in use, the mounting holes located on the lower part of the three sides of the second housing body 211 are air inlets, while the mounting holes located on the upper part of the three sides of the second housing body 211 are air outlets, resulting in better heat dissipation.

[0055] Unlike existing technologies, this invention provides a surface curing and molding system for popping beads based on ultraviolet light source curing. By sequentially passing the central tube 300 of the settling tube through the pre-curing device 100 and the secondary curing device 200, the popping beads in the central tube 300 are uniformly irradiated onto the surface of the popping beads by the two first reflective units 121 when passing through the pre-curing device 100, resulting in a highly focused and comprehensive irradiation effect, which is beneficial for popping bead molding. After passing through the secondary curing device 200, the light emitted by the second lamp unit 231 is uniformly irradiated onto the surface of the popping beads by the second reflective unit 221, resulting in a highly focused and comprehensive irradiation effect, which is beneficial for further curing of the popping bead surface. This solves the technical problem that traditional light sources are difficult to achieve stable high focus and comprehensive irradiation.

[0056] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
