Description

Technical Field

[0001] This invention relates to the field of burst bead production equipment technology, and in particular to a three-layer burst bead multi-process molding equipment. Background Technology

[0002] With increasing public concern about the relationship between smoking and health, and the ongoing global tobacco control movement, the research, development, production, and sales of low-tar, low-harm cigarettes have become an inevitable trend in the tobacco industry. However, reducing cigarette tar content brings new problems, such as reduced aroma and decreased comfort. Therefore, effective methods are needed to both specifically reduce the tar content in cigarette smoke and selectively add flavorings and additives to compensate for the drawbacks caused by lower tar levels.

[0003] Most regular cigarettes with reduced tar content suffer from two main problems: 1. Slightly less throat comfort and a more pronounced dryness; 2. Significantly reduced aroma quantity and concentration, directly impacting smoking comfort and physiological satisfaction. To address these issues, major domestic manufacturers are currently pursuing two research directions: 1. Designing flavoring and additive formulas and developing tobacco flavorings; 2. Adding various liquids to the filter.

[0004] Adding liquid to cigarette filters is typically achieved by adding flavor capsules. A flavor capsule is a small bead encased in a transparent shell, containing a liquid flavoring agent. Smokers break the shell, releasing the flavoring agent into the filter and altering the taste of the inhaled smoke. The liquid inside the flavor capsule is generally of two types: 1. oil-soluble flavoring; 2. water-soluble flavoring. Oil-soluble flavoring capsules are usually made by dripping a hydrophilic polymer. The resulting capsules are typically single-layered, then cooled and dried. The advantages of oil-soluble flavoring capsules are: simple equipment and low process requirements; they can compensate for the decrease in aroma quantity and concentration caused by reducing tar in cigarettes. The disadvantage is that they cannot hydrate the smoke, thus failing to improve throat comfort. Water-soluble flavoring capsules overcome the disadvantages of oil-soluble flavorings. On one hand, water-soluble flavorings can add flavor to the smoke; on the other hand, they humidify the smoke, improving the smoking experience and reducing throat dryness. Furthermore, water can dissolve ammonia, HCN (hydrogen cyanide), and other substances in flue gas, thereby further reducing harmful components in the flue gas. However, because the hydrophilic polymer shell cannot prevent the loss of water from water-soluble flavorings, an additional non-hydrophilic shell is needed to lock in the moisture. Therefore, the bursting beads encapsulating water-soluble flavorings usually have a three-layer structure.

[0005] Some methods for preparing three-layer burst beads employ a two-stage molding process, where a single-layer burst bead is first created, and then a second, non-hydrophilic outer shell is attached. For example, patent application CN110419775A discloses a method for preparing a water-resistant burst bead. The method involves using a metering pump to add a first photosensitive resin coating layer and a water-soluble core liquid to a room-temperature purified water protective solution via concentric droppers, forming a water-resistant burst bead precursor. This precursor is then washed with a 90% ethanol aqueous solution and air-dried. Next, the precursor is placed in a roller coating pan, and a second polyacrylic acid resin coating layer is sprayed onto it using a sprayer. After drying, the water-resistant burst beads are produced. For example, patent application CN110973699A discloses a water-bursting bead and its preparation method. The method involves dripping a core material (a mixed aqueous solution of water-soluble fragrance, calcium chloride, and xanthan gum) into a wall material solution (a mixture of sodium alginate and paraffin). After the reaction is complete, the beads in the wall material solution are filtered out and added to a calcium chloride cold water bath. The beads after the calcium chloride cold water bath are then added to a fatty amine for hydrophobic modification, resulting in water-bursting beads with a three-layer structure comprising a core material, a wall material, and a hydrophobic modified material. While this two-stage molding method for producing water-bursting beads does not require highly sophisticated equipment, the process is complex, labor costs are high, and the ethanol-water cleaning step poses safety hazards.

[0006] To address the shortcomings of the two-stage molding method, some research and development efforts have been undertaken on equipment and processes for the one-time dripping molding of three-layer bursting beads. For example, patent application CN109965327A discloses a seamless soft capsule dripping device and a dripping molding method. The device delivers three layers of liquid—shell liquid, intermediate liquid, and core liquid—via a delivery pump and delivery pipe to the outer, middle, and core layers of a dripping head system. The dripping head system then evenly drips the shell liquid, intermediate liquid, and core liquid together into a molding tube. A cooling pump then delivers coolant from a coolant tank into the molding tube. The coolant carries the seamless capsule out along a cooling hose, while the seamless capsule cools, solidifies, and hardens in the coolant. This approach uses the same molding process as single-layer dripping beads to produce three-layer structures. However, this requires simultaneously cooling and molding two different molding processes' liquids (shell liquid and intermediate liquid) in a single cooling medium, which is difficult to achieve in actual production. Furthermore, while the solution utilizes a camera to monitor the pellet forming process, it lacks a corresponding rejection device to remove defective pellets, which increases the complexity of subsequent processes. Additionally, the solution does not include a heating device for the flow channel of the capsule shell liquid; in actual production, if the machine stops, the cooled liquid will become trapped, preventing further production.

[0078] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0079] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0080] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0081] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0082] like Figures 1 to 17 As shown, this is one embodiment of the three-layer burst bead multi-process molding equipment of the present invention.

[0083] See Figure 1 and Figure 2 The three-layer bursting bead multi-process molding equipment in this embodiment includes a dripping device 1, a curing molding device 2, a visual inspection device 3, a rejection receiving device 4, and a control system 5.

[0084] Among them, combined Figures 3 to 6 The dripper device 1 is used to gather the core liquid, the intermediate layer liquid and the outer layer liquid to form a bursting bead, which is formed at the outlet of the dripper device 1.

[0085] Combination Figures 7 to 9 The curing and molding device 2 includes a popping bead transport channel 2.1, a cooling / heating curing component, and a light curing component. The upper end of the popping bead transport channel 2.1 is located below the outlet of the dripping device 1. The cooling / heating curing component is located at the upper end of the popping bead transport channel 2.1. This component separates the popping beads formed at the outlet of the dripping device 1 from the dripping device 1 using a flowing carrier liquid (such as oil), allowing the popping beads to flow into the popping bead transport channel 2.1 with the carrier liquid. The temperature of the carrier liquid cools / heats and / or cures the intermediate and / or outer layers of the popping beads. The light curing component is located in the middle of the popping bead transport channel 2.1. This component uses ultraviolet light to irradiate the popping bead transport channel 2.1, curing the intermediate and / or outer layers of the popping beads. The curing and molding device 2 performs cooling / heating curing and / or light curing on the popping beads, thus curing the layers (intermediate and outer layers) of the popping beads into a solid form.

[0086] Depending on the core liquid of the bursting beads, the outer liquid used in the bursting beads also varies, and therefore the curing and molding process of the outer liquid may also differ. The curing and molding device 2 in this embodiment is equipped with a cooling / heating curing component and a light curing component, which can realize various curing and molding processes according to actual needs, specifically including:

[0087] (1) When the liquid in the bursting beads is made of a cooling and curing material, a cooling and curing process is adopted, and a cooling / heating curing component is used to cool and cure the liquid in the bursting beads by using a carrier liquid with cooling and temperature control.

[0088] (2) When the liquid coating of the bursting beads is made of heat-curing material, a heat-curing process is adopted, and a cooling / heat curing component is used to heat and cure the liquid coating of the bursting beads by a carrier liquid with temperature control.

[0089] (3) When the liquid in the capsule is made of polymer monomers or oligomers, a photocuring process is used in the presence of a photoinitiator. A photocuring component is used to photocur the liquid in the capsule by ultraviolet irradiation.

[0090] (4) When one layer of the capsule uses a cooling / heating curing material and the other layer uses a polymer monomer or oligomer, a combination of cooling / heating curing process and light curing process is used, and cooling / heating curing component and light curing component are used to cure and shape the corresponding layer of capsule respectively.

[0091] (5) Depending on the required number of layers of the leather liquid, three-layer burst beads containing two layers of leather liquid can be produced, or two-layer burst beads containing one layer of leather liquid can be produced. Depending on the material of the leather liquid, one of the following processes can be selected: cooling curing process, heating curing process, and light curing process to cure and shape the leather liquid.

[0092] Therefore, the three-layer bursting bead multi-process molding equipment of this embodiment has multiple curing and molding processes, which can meet the production of bursting beads with different core liquid materials and different skin liquid materials, realize multi-purpose use of one machine, and thus effectively reduce equipment investment and floor space.

[0093] Combination Figures 10 to 12 The visual inspection device 3 includes a visual inspection channel 3.1 and a camera 3.2. The upper end of the visual inspection channel 3.1 is connected to the lower end of the popping bead transmission channel 2.1. After being solidified and formed through the popping bead transmission channel 2.1, the popping beads flow into the visual inspection channel 3.1 from the lower end of the popping bead transmission channel 2.1 along with the carrier liquid. The camera 3.2 acquires images of the popping beads passing through the visual inspection channel 3.1 to monitor the forming quality of the popping beads through visual inspection.

[0094] Combination Figure 13 The rejection and receiving device 4 includes a rejection component and a receiving component, the receiving component including at least two oil drain baskets 4.1.

[0095] The control system 5 is connected to the camera 3.2 of the vision inspection device 3 and the rejection component of the rejection receiving device 4. Based on the images captured by the camera 3.2, the control system 5 determines whether the corresponding burst beads are qualified or unqualified through image comparison. According to the judgment result, it controls the rejection component of the rejection receiving device 4 to separately discharge qualified and unqualified burst beads into the two oil-draining baskets 4.1 of the receiving component of the rejection receiving device 4, thereby achieving online automatic rejection of unqualified burst beads. This eliminates the need for subsequent manual inspection and rejection processes, simplifies subsequent production processes, and improves efficiency. Simultaneously, the control system 5 can also provide feedback adjustment to the burst bead production process parameters of the dripping device 1 and the curing molding device 2 based on the images captured by the camera 3.2 and the judgment results, to improve the molding quality and pass rate of the burst beads.

[0096] See Figures 3 to 6 In this embodiment, preferably, the dripping device 1 includes a housing 1.1, a vibrating diaphragm 1.2, a voice coil motor 1.3, a core liquid guide block 1.4, an intermediate layer guide block 1.5, and an outer layer guide block 1.6. The housing 1.1 has a core liquid cavity 1.1a located at the upper end of the housing 1.1, with an opening at its upper end. The vibrating diaphragm 1.2 covers the opening of the core liquid cavity 1.1a. The voice coil motor 1.3 acts on the vibrating diaphragm 1.2, causing it to vibrate intermittently. The core liquid guide block 1.4 has a core liquid flow channel 1.4a extending vertically through its interior. The upper end of the core liquid flow channel 1.4a connects to the lower end of the core liquid cavity 1.1a, and the lower end of the core liquid flow channel 1.4a has a core liquid outlet 1.4b. An intermediate layer guide block 1.5 is fitted over a core liquid guide block 1.4, with an intermediate layer liquid channel 1.5a formed between the intermediate layer guide block 1.5 and the core liquid guide block 1.4. An intermediate layer liquid outlet 1.5b is located at the lower end of the intermediate layer liquid channel 1.5a. An outer layer guide block 1.6 is fitted over the intermediate layer guide block 1.5, with an outer layer liquid channel 1.6a formed between the outer layer guide block 1.6 and the intermediate layer guide block 1.5. An outer layer liquid outlet 1.6b is located at the lower end of the outer layer liquid channel 1.6a. The core liquid outlet 1.4b, the intermediate layer liquid outlet 1.5b, and the outer layer liquid outlet 1.6b are concentrically arranged to form the outlet of the dripper device 1. During operation, the core fluid enters the core fluid chamber 1.1a and flows from the core fluid chamber 1.1a into the core fluid channel 1.4a. The intermediate layer and outer layer skin fluids enter the intermediate layer skin fluid channel 1.5a and the outer layer skin fluid channel 1.6a, respectively. The voice coil motor 1.3 starts, and the vibration of the voice coil motor 1.3 drives the vibrating diaphragm 1.2 to vibrate, causing a change in the volume of the core fluid chamber 1.1a. This forces the core fluid out through the core fluid outlet 1.4b at the lower end of the core fluid channel 1.4a. When the core fluid is extruded, due to the viscosity characteristics of the liquid, the extruded core fluid carries away a portion of the intermediate layer skin fluid. The intermediate layer liquid at the lower end of channel 1.5a is the intermediate layer liquid outlet 1.5b. Similarly, the intermediate layer liquid will carry away a portion of the outer layer liquid at the lower end of the outer layer liquid outlet 1.6b. Thus, the raw material for a bursting bead is separated from the core liquid channel 1.4a, the intermediate layer liquid channel 1.5a, and the outer layer liquid channel 1.6a, and gathers at the outlet at the lower end of the dripping device 1 to form a bursting bead. Then, the cooling / heating curing component of the curing device 2 carries away the bursting bead formed at the outlet of the dripping device 1 through the flowing carrier liquid.

[0097] In existing technologies, a metering pump is typically used to drive three raw materials to be added to a carrier fluid through a dropper. The temperature and flow rate of the carrier fluid cause the three raw materials to shrink into spherical shapes and break at the dropper outlet, forming small droplets. The dimensional accuracy of the popping beads produced in this way is very sensitive to the instantaneous temperature and flow rate fluctuations of the carrier fluid. In actual production, it is observed that the flow state of the carrier fluid at the dropper outlet is unstable due to the characteristics of fluid mechanics, with occasional undercurrents. The instantaneous temperature and flow rate of the carrier fluid are constantly changing. Therefore, this production method is mostly used in the production of single-layer droplets, and the dimensional accuracy of the droplets fluctuates greatly. Compared to existing technologies, the dripping device 1 in this embodiment uses a voice coil motor 1.3 to drive a vibrating diaphragm 1.2 to extrude the core liquid in an intermittent vibration-triggered manner. The core liquid can be extruded at a fixed frequency and a fixed volume through the core liquid outlet 1.4b, and the intermediate layer liquid and outer layer liquid are driven to converge with the extruded core liquid at the same fixed frequency and a fixed volume to form a bursting bead, which then enters the carrier flow liquid. The carrier flow liquid only needs to be able to shrink and shape the bursting bead and carry it away before the next frequency arrives. Therefore, the dimensional accuracy of the bursting beads produced by the dripping device 1 in this embodiment does not have high requirements for the instantaneous temperature fluctuation and instantaneous flow rate fluctuation of the carrier flow liquid. Furthermore, the high motion accuracy of the voice coil motor 1.3 can determine the content of the core liquid, intermediate layer liquid, and outer layer liquid in each bursting bead. This is more conducive to controlling the improvement of bursting bead accuracy and adjusting production parameters in the actual production process, thereby achieving high efficiency, high forming accuracy, and high pass rate in the production of three-layer bursting beads.

[0098] In this embodiment, the voice coil motor 1.3 is connected to the control system 5. The control system 5 can provide feedback and automatically adjust the working parameters of the voice coil motor 1.3 based on the popping bead image and judgment result acquired by the camera 3.2 of the vision inspection device 3, so as to ensure the molding quality and pass rate of the popping beads.

[0099] See Figure 1 , Figure 2 and Figure 5In this embodiment, preferably, the upper end of the intermediate layer liquid flow channel 1.5a is provided with an intermediate layer liquid inlet 1.5c that is connected to the intermediate layer liquid flow channel 1.5a. The intermediate layer liquid inlet 1.5c is connected to the intermediate layer liquid raw material tank 1.5e through the intermediate layer liquid throat 1.5d. The intermediate layer liquid in the intermediate layer liquid raw material tank 1.5e is pumped into the intermediate layer liquid flow channel 1.5a through the intermediate layer liquid throat 1.5d and the intermediate layer liquid inlet 1.5c. The upper end of the outer layer liquid flow channel 1.6a is provided with an outer layer liquid inlet 1.6c, which is connected to the outer layer liquid flow channel 1.6a. The outer layer liquid inlet 1.6c is connected to the outer layer liquid raw material tank 1.6e through the outer layer liquid throat 1.6d. The outer layer liquid in the outer layer liquid raw material tank 1.6e is pumped through the outer layer liquid throat 1.6d and the outer layer liquid inlet 1.6c into the outer layer liquid flow channel 1.6a. The outer layer liquid throat 1.5d and the outer layer liquid throat 1.6d have high temperature control accuracy.

[0100] In existing technologies, the raw material tank for the molten leather of the dripping beads is typically designed at the top of the dripping device. This allows the temperature of the raw material tank to be used to keep the molten leather in the pipeline warm. Because the pipeline is short, even if the molten leather in the pipeline solidifies due to a shutdown, it can quickly thaw again, and the temperature fluctuation during production is small. However, placing the raw material tank at the top of the device requires operators to carry raw materials or tools and climb a ladder to change or maintain the raw material tank, which is extremely inconvenient and poses a production safety hazard. Compared to existing technologies, this embodiment uses a throat tube with high temperature control accuracy to deliver the molten leather to the dripping device 1. The raw material tank can be placed on a platform on one side of the dripping device 1, instead of being placed at the top of the dripping device 1. This ensures that the temperature fluctuation of the molten leather is small, increases the convenience of changing and maintaining the raw material tank, and reduces production safety hazards.

[0101] In addition, the upper end of the core liquid chamber 1.1a is provided with a core liquid inlet 1.1c that is connected to the core liquid chamber 1.1a. The core liquid inlet 1.1c is connected to the core liquid raw material tank through a pipeline to introduce core liquid into the core liquid chamber 1.1a.

[0102] See Figure 5In this embodiment, preferably, the opening of the core fluid chamber 1.1a is located on the upper end face of the outer shell 1.1, the vibrating diaphragm 1.2 is pressed onto the upper end face of the outer shell 1.1 by the upper pressure cover 1.7, the voice coil motor 1.3 is connected to the upper end of the piston rod 1.8, the upper end of the piston rod 1.8 is connected to the voice coil motor 1.3 by a coupling 1.9, the lower end of the piston rod 1.8 is provided with a flange 1.8a, and the lower end of the piston rod 1.8 passes through the vibrating diaphragm 1.2 and through the flange. 1.8a is in contact with the lower surface of the diaphragm 1.2. A pressure ring 1.20 is inserted through the piston rod 1.8, which is in contact with the upper surface of the diaphragm 1.2. A clamping nut 1.21 is used to press and fix the pressure ring 1.20, the diaphragm 1.2 and the flange 1.8a. This achieves a fixed connection between the voice coil motor 1.3 and the diaphragm 1.2, so that the voice coil motor 1.3 can act on the diaphragm 1.2 and drive the diaphragm 1.2 to vibrate intermittently.

[0103] Furthermore, the outer casing 1.1, upper pressure cover 1.7, pressure ring 1.20, and flange 1.8a all have rounded corners at the corners that contact the vibrating diaphragm 1.2 and are close to the core fluid cavity 1.1a. The vibrating diaphragm 1.2 vibrates in a drum-shaped trajectory under the action of the voice coil motor 1.3. Rounding the corners of these four components—outer casing 1.1, upper pressure cover 1.7, pressure ring 1.20, and flange 1.8a—at the corners that contact the vibrating diaphragm 1.2 and are close to the core fluid cavity 1.1a increases the contact area with the diaphragm 1.2, improves the stability of the diaphragm 1.2's vibration, prevents rapid fatigue fracture due to stress concentration, and extends the lifespan of the diaphragm 1.2.

[0104] See Figure 5 In this embodiment, preferably, the outer shell 1.1 is provided with an exhaust hole 1.1b, which is located at the top of the core fluid cavity 1.1a. The exhaust hole 1.1b connects the core fluid cavity 1.1a with the external space of the outer shell 1.1. Air in the core fluid cavity 1.1a can be discharged through the exhaust hole 1.1b, so that the compressibility of the internal volume of the core fluid cavity 1.1a remains constant.

[0105] In this embodiment, preferably, the contact surfaces between the outer shell 1.1, the core liquid guide block 1.4, the intermediate layer guide block 1.5, and the outer layer guide block 1.6 are all precision-machined using a CNC machine tool, with dimensional and positional tolerances controlled at the micrometer level. Furthermore, the core liquid outlet 1.4b at the lower end of the core liquid guide block 1.4 is ground using a high-precision grinding machine, and the positional tolerance between it and the mounting mating surface at the upper end of the core liquid guide block 1.4 is also controlled at the micrometer level. Similarly, the intermediate layer liquid outlet 1.5b and the outer layer liquid outlet 1.6b also maintain micrometer-level positional tolerances with their corresponding mounting mating surfaces. Therefore, the outer shell 1.1, core liquid guide block 1.4, intermediate layer guide block 1.5, and outer layer guide block 1.6 of the dripper device 1 can automatically center and maintain high concentricity and dimensional accuracy after assembly, without requiring manual secondary adjustment. Furthermore, the high processing and assembly precision ensures that the cross-sectional area of ​​each layer of the three-layer burst beads is very close to the theoretical calculation value, and the volume of the two layers of skin fluid carried by each core fluid is also very close to the calculation value of the physiotherapy, thus ensuring the burst bead forming precision.

[0106] See Figure 5 In this embodiment, preferably, the core fluid cavity 1.1a is located at the upper end of the outer shell 1.1, and an installation cavity 1.1d communicating with the lower end of the core fluid cavity 1.1a is formed on the lower end surface of the outer shell 1.1. The upper ends of the core fluid guide block 1.4, the middle layer guide block 1.5, and the outer layer guide block 1.6 are all located within the installation cavity 1.1d, while the lower ends of the core fluid guide block 1.4, the middle layer guide block 1.5, and the outer layer guide block 1.6 extend out of the installation cavity 1.1d. A lower pressure cap 1.24 is provided between the outer layer guide block 1.6 and the lower end of the installation cavity 1.1d to press and fix the outer layer guide block 1.6, the middle layer guide block 1.5, and the core fluid guide block 1.4 within the installation cavity 1.1d of the outer shell 1.1. The lower end of the outer guide block 1.6 is covered with a heat insulation sleeve 1.25. The heat insulation sleeve 1.25 is made of a material with low thermal conductivity. When the outlet of the dripping device 1 is immersed in the carrier liquid, it can greatly slow down the heat conduction speed between the dripping device 1 and the carrier liquid, reduce the temperature fluctuation of the core liquid and the outer liquid raw materials in the dripping device 1, and thus improve the molding quality of the bursting beads.

[0107] Furthermore, in this embodiment, the outer shell 1.1, the core liquid guide block 1.4, the intermediate layer guide block 1.5, and the outer layer guide block 1.6 are all made of thermally conductive materials, preferably metal materials. See also Figure 3 and Figure 5The outer shell 1.1 contains a heating rod 1.22 and a first temperature probe 1.23 for monitoring the heating temperature of the heating rod 1.22. The heating rod 1.22 is inserted into the outer shell 1.1 from the upper end and extends to the lower end of the outer shell 1.1. Several heating rods 1.22 can be provided for uniform heating. When the heating rod 1.22 is heating, through the thermal conduction effect of the heat-conducting material, the outer shell 1.1 and the core liquid guide block 1.4, intermediate layer guide block 1.5 and outer layer guide block 1.6 installed in the outer shell 1.1 can be heated simultaneously. This keeps the core liquid, intermediate layer skin liquid and outer layer skin liquid flowing through the core liquid channel 1.4a, intermediate layer skin liquid channel 1.5a and outer layer skin liquid channel 1.6a under a suitable constant temperature state, thereby ensuring that the three layers of raw materials can be transported and formed under a constant temperature state, making the forming quality of the three-layer burst beads more stable. At the same time, it can also prevent the skin liquid from condensing and clogging the flow channels due to machine stoppage.

[0108] In this embodiment, both the heating rod 1.22 and the first temperature probe 1.23 are connected to the control system 5. The first temperature probe 1.23 feeds back the detected heating temperature information to the control system 5 in real time. The control system 5 automatically adjusts and controls the heating temperature of the heating rod 1.22 according to the received heating information and the popping bead production process parameters to meet the production requirements.

[0109] See Figure 5 In this embodiment, preferably, the cavity wall surface at the lower end of the mounting cavity 1.1d of the outer shell 1.1 is an inlet surface 1.1e that slopes outward from top to bottom. This forms a long inlet angle at the lower end of the mounting cavity 1.1d, which makes it easier to install and remove the core liquid guide block 1.4, the intermediate layer guide block 1.5 and the outer layer guide block 1.6 in the outer shell 1.1, and facilitates the disassembly and assembly operation when changing the specifications of the popping beads produced.

[0110] See Figure 6 In this embodiment, preferably, the outer peripheral side of the outer guide block 16 located at the outer liquid outlet 16b extends outward to form a convex ring 16f. The convex ring 16f can prevent the extruded three-layer bursting bead raw material from climbing upward along the outer peripheral side of the outer guide block 16 due to the liquid tension.

[0111] See Figures 7 to 9In this embodiment, preferably, the cooling / heating curing component of the curing and molding device 2 includes a fixed base 2.2, a curing and molding tank 2.3, and an overflow tank 2.4. The fixed base 2.2 is fitted over the popping bead transmission channel 2.1, forming a cavity between the fixed base 2.2 and the popping bead transmission channel 2.1 that is closed at the lower end and open at the upper end. The curing and molding tank 2.3 extends vertically through the interior, is fitted over the popping bead transmission channel 2.1, and its lower end is connected to the upper end of the fixed base 2.2. The interior of the curing and molding tank 2.3 communicates with the cavity between the fixed base 2.2 and the popping bead transmission channel 2.1, thereby forming a curing and molding cavity 2.3a that is closed at the lower end and open at the upper end between the fixed base 2.2, the curing and molding tank 2.3, and the popping bead transmission channel 2.1. An overflow trough 2.4 is fitted onto a curing tank 2.3. The lower end face of the overflow trough 2.4 is connected and fixed to the upper end face of the fixing base 2.2. An overflow cavity 2.4a, which is closed at the lower end and open at the upper end, is formed between the overflow trough 2.4 and the curing tank 2.3. The upper end face of both the popping bead transmission channel 2.1 and the upper end face of the overflow trough 2.4 are lower than the upper end face of the curing tank 2.3. The fixing base 2.2 is provided with a carrier flow liquid inlet 2.2a, and the overflow trough 2.4 is provided with a carrier flow liquid overflow outlet 2.4b. A carrier fluid with the required temperature for the popping bead production process enters the curing and molding chamber 2.3a from the carrier fluid inlet 2.2a on the fixed base 2.2 and flows upward. When it reaches the upper end face of the popping bead transfer channel 2.1, part of the carrier fluid flows into the popping bead transfer channel 2.1, while the other part continues to flow upward to the upper end face of the curing and molding tank 2.3 and overflows into the overflow chamber 2.4a, finally flowing out from the carrier fluid overflow outlet 2.4b on the overflow tank 2.4. Thus, a flowing carrier fluid is formed on the upper end face of the popping bead transfer channel 2.1. The lower outlet of the dripping device 1 is immersed in the carrier fluid at this location, which allows the carrier fluid to separate the popping beads formed at the outlet of the dripping device 1 from the dripping device 1 and carry them into the popping bead transfer channel 2.1. At the same time, the temperature of the carrier fluid cools / heats and solidifies the middle and / or outer layers of the popping beads.

[0112] See Figure 9 In this embodiment, preferably, a porous flow stabilizer plate 2.5 and a honeycomb flow stabilizer block 2.6 are sequentially fitted from bottom to top between the curing and molding tank 2.3 and the popping bead transmission channel 2.1. When the carrier fluid entering the curing and molding chamber 2.3a from the carrier fluid inlet 2.2a on the fixed seat 2.2 flows upward, it first passes through the porous flow stabilizer plate 2.5 for the first stage of flow stabilization, then through the honeycomb flow stabilizer block 2.6 for the second stage of flow stabilization, and then reaches the upper end face of the popping bead transmission channel 2.1 and the upper end face of the curing and molding tank 2.3. After undergoing two stages of flow stabilization, the carrier fluid overflows to the lower end outlet of the dripping device 1, which can minimize the fluctuation of the carrier fluid flow rate.

[0113] Preferably, the porous flow stabilizer plate 2.5 is supported on the spacer ring 2.7, the spacer ring 2.7 is fixedly sleeved on the popping bead transmission channel 2.1 and located inside the fixing seat 2.2, and fixing rings 2.8 are sleeved on the upper and lower ends of the honeycomb flow stabilizer block 2.6 on the popping bead transmission channel 2.1, and the fixing rings 2.8 press and fix the honeycomb flow stabilizer block 2.6 and the porous flow stabilizer plate 2.5 tightly.

[0114] Preferably, a second temperature probe 2.9 is provided on the mounting base 2.2. The second temperature probe 2.9 is used to monitor the temperature of the carrier fluid at the carrier fluid inlet 2.2a, that is, to monitor the temperature of the carrier fluid before it comes into contact with the dropper device 1. In this embodiment, the second temperature probe 2.9 is connected to the control system 5. The second temperature probe 2.9 feeds back the detected carrier fluid temperature information to the control system 5 in real time. The control system 5 automatically adjusts and controls the temperature of the carrier fluid entering the carrier fluid inlet 2.2a according to the received carrier fluid temperature information and the popping bead production process parameters to ensure that it meets the production requirements.

[0115] See Figures 7 to 9 In this embodiment, preferably, the photocuring component of the curing and molding device 2 includes a hollow chamber 2.10 and an ultraviolet lamp 2.11 disposed inside the chamber 2.10. The popping bead transport channel 2.1 extends vertically through the chamber 2.10, and the ultraviolet lamp 2.11 is arranged on the outer periphery of the popping bead transport channel 2.1. When the popping beads flow through the popping bead transport channel 2.1 with the carrier liquid, the ultraviolet lamp 2.11 can irradiate the popping beads flowing in the carrier liquid within the popping bead transport channel 2.1, thereby photocuring the middle and / or outer layers of the popping beads. In this embodiment, the ultraviolet lamp 2.11 is connected to the control system 5, which automatically controls the ultraviolet lamp 2.11 to turn on or off according to the needs of the popping bead production and molding process.

[0116] Preferably, the chamber 2.10 includes a vertically arranged back plate 2.10a, a chamber cover 2.10b connected to the back plate 2.10a, a top plate 2.10c connecting the upper ends of the back plate 2.10a and the chamber cover 2.10b, and a bottom plate 2.10d connecting the lower ends of the back plate 2.10a and the chamber cover 2.10b. The back plate 2.10a, the chamber cover 2.10b, the top plate 2.10c, and the bottom plate 2.10d form a hollow chamber 2.10. The top plate 2.10c is connected to the lower end of the cooling / heating curing component via a support 2.12. Specifically, the support 2.10 is fixedly sleeved on the popping bead transmission channel 2.1, the top plate 2.10c is connected to the lower end of the support 2.12, and the upper end of the support 2.12 is fixedly connected to the lower end face of the fixing seat 2.2 by screws. Thus, the bead transport channel 2.1, the cooling / heating curing component, and the photocuring component are connected and fixed together.

[0117] See Figure 7 and Figure 9 In this embodiment, preferably, the curing and molding device 2 further includes a first lifting component, which is used to drive the popping bead transmission channel 2.1, the cooling / heating curing component, and the light curing component to move up and down synchronously. By driving the popping bead transmission channel 2.1, the cooling / heating curing component, and the light curing component to move up and down synchronously by the first lifting component, the distance between the overflow liquid surface of the carrier fluid at the upper end of the popping bead transmission channel 2.1 and the outlet at the lower end of the dripping head device 1 can be adjusted, that is, the depth at which the outlet at the lower end of the dripping head device 1 is inserted into the carrier fluid can be adjusted, thereby adjusting the flow state of the carrier fluid.

[0118] Preferably, the first lifting assembly includes a first servo motor 2.13 and a first linear module 2.14 connected to the first servo motor 2.13. The first linear module 2.14 is driven by the first servo motor 2.13 to perform linear motion, thereby synchronously lifting and lowering the pod delivery channel 2.1, the cooling / heating curing assembly, and the photocuring assembly. The structure of the first linear module 2.14 is not limited; for example, a ball screw structure can be used to convert the rotary motion of the servo motor into linear motion. In this embodiment, the first linear module 2.14 is connected to the back plate 2.10a of the chamber 2.10. The first linear module 2.14 converts the rotary motion of the first servo motor 2.13 into linear motion, thereby causing the chamber 2.10 to perform linear motion accordingly, thus synchronously lifting and lowering the pod delivery channel 2.1, the cooling / heating curing assembly, and the photocuring assembly.

[0119] In this embodiment, the first servo motor 2.13 is connected to the control system 5. The control system 5 automatically adjusts and controls the operation of the first servo motor 2.13 in real time according to the popping bead production process parameters. This allows the control system to control and adjust the distance between the overflow liquid surface of the carrier flow liquid at the upper end of the popping bead transmission channel 2.1 and the outlet at the lower end of the dripping head device 1 in real time.

[0120] See Figures 10 to 12In this embodiment, preferably, the visual inspection channel 3.1 of the visual inspection device 3 includes a square channel 3.1a with a square cross-section and a circular channel 3.1b with a circular cross-section. The cross-section of the popping bead transmission channel 2.1 is circular. The lower end of the popping bead transmission channel 2.1 is smoothly connected to the upper end of the square channel 3.1a through a circular-to-square channel 3.1c with equal cross-sectional area. The lower end of the square channel 3.1a is smoothly connected to the upper end of the circular channel 3.1b through a square-to-circular channel 3.1d with equal cross-sectional area. The lower end of the circular channel 3.1b leads to the rejection component of the rejection receiving device 4. The camera 3.2 is located on the outer periphery of the square channel 3.1a. After being solidified in the popping bead transport channel 2.1, the popping beads flow from the lower end of the transport channel 2.1 into the vision inspection channel 3.1 along with the carrier liquid. They then sequentially pass through a round-to-square channel 3.1c, a square channel 3.1a, a square-to-round channel 3.1d, and a circular channel 3.1b. The camera 3.2 captures images of the popping beads passing through the square channel 3.1a from the outer periphery of the square channel 3.1a. Thus, in this embodiment, the vision inspection device 3 smoothly transitions the circular popping bead transport channel 2.1 into a square channel 3.1a through the round-to-square channel 3.1c, capturing images of the popping beads in the square channel 3.1a. Then, it smoothly transitions the square channel 3.1a into a circular channel 3.1b through the square-to-round channel 3.1d. This avoids the image distortion caused by the circular channel when capturing images of the popping beads on the outer periphery of the circular channel, and also does not alter the flow rate of the carrier liquid.

[0121] See Figure 12 In this embodiment, preferably, an optical glass 3.3 is provided circumferentially in the middle of the square channel 3.1a, and a visual observation window 3.4 is provided on the outer periphery of the square channel 3.1a at a position corresponding to the optical glass 3.3. A camera 3.2 is located on the outer periphery of the visual observation window 3.4. The camera 3.2 acquires images of the popping beads passing through the square channel 3.1a through the visual observation window 3.4 and the optical glass 3.3 on the outer periphery of the square channel 3.1a.

[0122] Furthermore, a camera light source 3.5 is provided on the outer periphery of the visual observation window 3.4. The camera light source 3.5 is positioned opposite the camera 3.2 on opposite sides of the visual observation window 3.4. The light emitted by the camera light source 3.5 passes through the visual observation window 3.4 and the optical glass 3.3 and illuminates the square channel 3.1a, which is beneficial for the camera 3.2 to capture a clear image of the popping beads passing through the square channel 3.1a.

[0123] In this embodiment, preferably, the camera light source 3.5 is mounted on the light source bracket 3.6.

[0124] In this embodiment, preferably, the camera 3.2 is mounted on the camera bracket 3.7.

[0125] See Figure 12 In this embodiment, preferably, the round-to-square channel 3.1c is located within the round-to-square conversion block 3.8, the square channel 3.1a is located within the square block 3.9, the square-to-round channel 3.1d is located within the square-to-round conversion block 3.10, and the round channel 3.1b is located within the pagoda elbow 3.11. The round-to-square conversion block 3.8, the square block 3.9, the square-to-round conversion block 3.10, and the pagoda elbow 3.11 are connected sequentially from top to bottom. The upper end of the round-to-square conversion block 3.8 is connected to the lower end of the popping bead transmission channel 2.1, and the lower end of the pagoda elbow 3.11 leads to the rejection component of the rejection receiving device 4.

[0126] Preferably, the round-to-square conversion block 3.8 and the square block 3.9 are connected and fixed together by screws, and the square block 3.9 and the square-to-round conversion block 3.10 are connected and fixed together by screws.

[0127] Preferably, the upper end of the pagoda elbow 3.11 is connected to the clamp adapter 3.13 via a clamp 3.12, and the clamp adapter 3.13 is connected and fixed to the lower end of the square-to-round conversion block 3.10 via screws.

[0128] See Figure 10 and Figure 11 In this embodiment, preferably, the visual inspection device 3 further includes a sensor 3.14, which is used to detect whether a popping bead passes through the visual inspection channel 3.1. The sensor 3.14 is preferably a through-beam photoelectric sensor, and the sensor 3.14 is connected to the control system 5. In this embodiment, the sensor 3.14 is located on the outer periphery of the visual inspection channel 3.1, specifically on the outer periphery of the upper end of the square channel 3.1a, and the position of the sensor 3.14 is higher than the position of the camera 3.2. When the popping bead passes through the visual inspection channel 3.1, the sensor 3.14 is triggered when it reaches the square channel 3.1a and passes the sensor 3.14. That is, the sensor 3.14 detects that a popping bead has passed by. The sensor 3.14 transmits the detected trigger information to the control system 5. The control system 5 controls the camera 3.2 to take pictures based on the received trigger information, thereby acquiring images of the passing popping bead. The camera 3.2 transmits the acquired images to the control system 5. The control system 5 compares the received images to determine whether the passing popping bead is a qualified popping bead or an unqualified popping bead. Based on the determination result, it controls the rejection component of the rejection receiving device 4 to separate and discharge qualified and unqualified popping beads, and provides feedback to adjust the popping bead production process parameters, automatically adjusting the parameters of each control point of the equipment.

[0129] In this embodiment, preferably, the sensor 3.14 is mounted on the sensor bracket 3.15.

[0130] See Figures 13 to 16 In this embodiment, preferably, the rejection component of the rejection receiving device 4 includes a discharge bend 4.2, a baffle plate 4.3, a flow guide flap 4.4, and a drive mechanism. The upper end of the discharge bend 4.2 is connected to the lower end of the visual inspection channel 3.1. In this embodiment, the upper end of the discharge bend 4.2 is connected to the lower end of the pagoda bend 3.11. After passing through the visual inspection channel 3.1, the popping beads flow into the discharge bend 4.2 with the carrier liquid. Two baffle plates 4.3 are provided, and the two baffle plates 4.3 are arranged opposite each other at a distance below the lower end of the discharge bend 4.2. The flow guide flap 4.4 is provided between the two baffle plates 4.3, and the flow guide flap 4.4 divides the space between the two baffle plates 4.3 into two independent drop troughs 4.5. One drop trough 4.5 serves as the drop trough for qualified popping beads, and the other drop trough 4.5 serves as the drop trough for unqualified popping beads. Two discharge troughs 4.5 lead to two drain baskets 4.1 of the receiving assembly, one of which serves as the drain basket for qualified popping beads, and the other as the drain basket for unqualified popping beads. A drive mechanism is connected to a guide flap 4.4, which rotates to position one of the discharge troughs 4.5 below the lower end of the discharge bend 4.2, while the other avoids the lower end of the discharge bend 4.2. This allows qualified and unqualified popping beads to be separately discharged into the qualified and unqualified popping bead drain baskets, respectively. The drive mechanism is connected to the control system 5. The control system 5 controls the drive mechanism's action based on the comparison and judgment results of the popping bead images captured by the camera 3.2: when the judgment result is a qualified popping bead, the control system 5 controls the drive mechanism to drive the guide flap 4.4 to rotate until the qualified popping bead dropping chute is located at the lower end of the discharge bend 4.2, so that the corresponding popping bead falls into the qualified popping bead drain basket through the qualified popping bead dropping chute; when the judgment result is a defective popping bead, the control system 5 controls the drive mechanism to drive the guide flap 4.4 to rotate until the defective popping bead dropping chute is located at the lower end of the discharge bend 4.2, so that the corresponding popping bead falls into the defective popping bead drain basket through the defective popping bead dropping chute, thereby automatically removing the defective popping bead. This allows for the automatic removal of a section of popping bead with quality problems based on the detection results of the visual inspection device 3.

[0131] In this embodiment, the receiving component may be provided with three oil drain baskets 4.1, two of which serve as qualified and unqualified burst beads oil drain baskets respectively to receive qualified and unqualified burst beads, and the third oil drain basket 4.1 serves as a spare oil drain basket to replace the qualified or unqualified burst beads when the oil drain basket is full of burst beads and needs to be removed and poured out.

[0132] In this embodiment, see Figure 13 and Figure 15Preferably, the drive mechanism includes a drive shaft 4.8 and a rotating electromagnet 4.9. The drive shaft 4.8 is rotatably supported on a fixed plate 4.7 via a bearing 4.6. The rotating electromagnet 4.9 is mounted on the fixed plate 4.7 and is connected to one end of the drive shaft 4.8. The other end of the drive shaft 4.8 is connected to a flow guide flap 4.4. The rotating electromagnet 4.9 provides rotational driving force to the drive shaft 4.8 and drives the flow guide flap 4.4 to rotate. The rotating electromagnet 4.9 is connected to a control system 5, and the control system 5 controls the operation of the rotating electromagnet 4.9.

[0133] Preferably, in this embodiment, a support column 4.10 is provided on the fixing plate 4.7, and a rotating electromagnet 4.9 is provided on the mounting plate 4.11, with the mounting plate 4.11 connected to the support column 4.10.

[0134] Preferably, in this embodiment, a protective cover 4.12 is provided on the fixing plate 4.7, and the rotating electromagnet 4.9 is housed in the protective cover 4.12 to provide protection.

[0135] Preferably, in this embodiment, the discharge bend 4.2 is mounted on the fixing plate 4.7 by a pipe clamp 4.13.

[0136] See Figure 13 and Figure 15 In this embodiment, preferably, the rejection receiving device 4 further includes a second lifting component, which is used to drive the rejection component to rise and fall. The lower end of the discharge bend 4.2 in the rejection component is the discharge port of the three-layer bursting bead multi-process molding equipment of this embodiment. The bursting beads formed at the lower end outlet of the dripping head device 1 flow sequentially through the bursting bead transmission channel 2.1, the visual inspection channel 3.1 and the discharge bend 4.2 with the carrier flowing liquid, and then flow out from the lower end of the discharge bend 4.2 and are discharged into the oil drain basket 4.1 of the receiving component. Therefore, the lower end surface of the discharge bend 4.2 is the outlet liquid surface of the carrier flowing liquid. The height difference between the outlet liquid surface of the carrier flowing liquid and the overflow liquid surface of the carrier flowing liquid at the upper end surface of the bursting bead transmission channel 2.1 determines the flow rate of the carrier flowing liquid. By driving the removal component to lift and lower through the second lifting component, the height position of the lower end face of the discharge bend 4.2 can be adjusted, thereby adjusting the height difference between the outlet liquid surface of the carrier fluid and the overflow liquid surface of the carrier fluid, and thus adjusting and controlling the flow rate of the carrier fluid.

[0137] Preferably, the second lifting assembly includes a second servo motor 4.14 and a second linear module 4.15 connected to the second servo motor 4.14. The second linear module 4.15 is driven by the second servo motor 4.14 to perform linear motion and drive the rejection assembly to rise and fall. The structure of the second linear module 4.15 is not limited; for example, a ball screw structure can be used to convert the rotary motion of the servo motor into linear motion. In this embodiment, the second linear module 4.15 is connected to the protective cover 12. The second linear module 4.15 converts the rotary motion of the second servo motor 4.14 into linear motion and drives the protective cover 12 to perform linear motion accordingly, thereby driving the rejection assembly to rise and fall as a whole.

[0138] In this embodiment, the second servo motor 4.14 is connected to the control system 5. The control system 5 automatically adjusts and controls the operation of the second servo motor 4.14 in real time according to the popping bead production process parameters. This allows for real-time control and adjustment of the height difference between the carrier flow liquid outlet surface at the lower end face of the discharge bend 4.2 and the carrier flow liquid overflow surface at the upper end face of the popping bead transmission channel 2.1.

[0139] See Figure 16 In this embodiment, preferably, the receiving component of the receiving device 4 includes an oil tank 4.16. The oil tank 4.16 is equipped with a filter screen 4.17 that divides its internal space into upper and lower layers. At least two drain baskets 4.1 are located in the upper layer of the oil tank 4.16, above the filter screen 4.17. The drain baskets 4.1 use their mesh to separate the popping beads from the carrier liquid. The popping beads remain in the drain baskets 4.1, while the carrier liquid flows out through the mesh and falls into the oil tank 4.16. The filter screen 4.17 filters the carrier liquid flowing out of the drain baskets 4.1, removing impurities. The carrier fluid, after being filtered by the filter screen 4.17, is stored in the lower space of the oil tank 4.16. After temperature control, it can be transported to the carrier fluid inlet 2.2a on the fixed seat 2.2 of the cooling / heating curing component of the curing and molding device 2 for recycling.

[0140] Preferably, the filter screen 4.17 is disposed on the skeleton perforated plate 4.18, which is connected to the oil tank 4.16 via the screen outer frame 4.19. This allows for easy disassembly and cleaning of the filter screen 4.17 and replacement with screens of other mesh sizes, resulting in lower impurity content in the carrier fluid and less impact on the cooling / heating curing process of the popping beads.

[0141] Preferably, a silica gel plate 4.20 is provided below the filter screen 4.17. The silica gel plate 4.20 has through holes running vertically through it, allowing the carrier liquid to pass through. The silica gel plate 4.20 serves a heat preservation function.

[0142] Preferably, the outer sheet metal of the fuel tank 4.16 is filled with foamed thermal insulation material to achieve the function of heat preservation.

[0143] By setting up a silicone plate 4.20 and filling the outer sheet metal of the oil tank 4.16 with foamed thermal insulation material, the thermal conduction effect between the carrier fluid in the oil tank 4.16 and the external environment can be significantly reduced, which reduces the generation of condensate and the temperature fluctuation of the carrier fluid.

[0144] See Figure 17 In this embodiment, preferably, the lower space of the oil tank 4.16 is provided with a first outlet 4.16a, which is connected to the input port of the variable frequency water pump. The output port of the variable frequency water pump leads to the cooling / heating curing component of the curing molding device 2, and the carrier fluid overflowing from the cooling / heating curing component leads to the upper space of the oil tank 4.16. In this embodiment, the output port of the variable frequency water pump is connected to the carrier fluid inlet 2.2a on the fixing seat 2.2 of the cooling / heating curing component through a pipeline; the carrier fluid overflow outlet 2.4b on the overflow tank 2.4 of the cooling / heating curing component leads to the upper space of the oil tank 4.16 through a pipeline, so that the carrier fluid flowing out from the carrier fluid overflow outlet 2.4b is also recovered into the oil tank 4.16. The carrier fluid in the oil tank 4.16 is then circulated to the cooling / heating curing component by the variable frequency water pump. Preferably, a first filter 4.21 is provided at the first outlet 4.16a of the oil tank 4.16, and the first outlet 4.16a is connected to the input port of the variable frequency water pump through the first filter 4.21.

[0145] See Figure 17 In this embodiment, preferably, a second outlet 4.16b and an inlet 4.16c are provided on one side of the lower space of the fuel tank 4.16, combined with Figure 1 and Figure 2The second outlet 4.16b is connected to the input port of the industrial chiller 6, and the output port of the industrial chiller 6 is connected to the inlet 4.16c. The industrial chiller 6 cools or heats the carrier fluid in the oil tank 4.16. The water pump of the industrial chiller 6 draws the carrier fluid from the oil tank 4.16 through the second outlet 4.16b, cools or heats it in the industrial chiller 6 for temperature control, and then sends it back to the oil tank 4.16 through the inlet 4.16c. This achieves the regulation and control of the temperature of the carrier fluid in the oil tank 4.16, that is, the temperature regulation and control of the carrier fluid delivered to the cooling / heating curing component. Using the carrier fluid with temperature controlled by the industrial chiller 6 as the cooling / heating curing molding fluid for the burst beads provides a rapid and gentle cooling / heating curve for the three-layer burst beads, without any production safety hazards. In this embodiment, the industrial chiller 6 is connected to the control system 5, which automatically adjusts and controls the cooling or heating temperature of the carrier fluid by the industrial chiller 6 according to the burst bead production process parameters. Preferably, a second filter 4.22 and a third filter 4.23 are respectively provided at the second outlet 4.16b and the inlet 4.16c of the oil tank 4.16. The second outlet 4.16b is connected to the input port of the industrial chiller 6 through the second filter 4.22, and the inlet 4.16c is connected to the output port of the industrial chiller 6 through the third filter 4.23.

[0146] Preferably, a guide tube 4.24 is provided in the lower space of the fuel tank 4.16, one end of the guide tube 4.24 is connected to the inlet 4.16c, and the other end of the guide tube 4.24 extends horizontally to the other side of the lower space of the fuel tank 4.16.

[0147] Preferably, a vertical partition 4.25 is provided in the middle of the lower space of the fuel tank 4.16, which divides the lower space of the fuel tank 4.16 into two interconnected areas, and a guide tube 4.24 passes through the vertical partition 4.25.

[0148] By setting a vertical baffle 4.25 located in the middle of the lower space of the oil tank 4.16 and a guide pipe 4.24 passing through the vertical baffle 4.25, the flow direction of the carrier fluid in the oil tank 4.16 can be interfered with, preventing short circuits between the first outlet 4.16a, the second outlet 4.16b and the inlet 4.16c, which is more conducive to maintaining a balanced temperature distribution of the carrier fluid in the oil tank 4.16.

[0149] See Figure 17 In this embodiment, preferably, the lower space of the oil tank 4.16 is provided with a drain outlet 4.16d, and a drain valve 4.26 is provided at the drain outlet 4.16d.

[0150] See Figure 1 and Figure 2In this embodiment, the control system 5 includes a controller, which is a conventional controller, such as a PLC controller or a microcontroller. The control system 5 may also include an electrical control cabinet 51, in which the controller and its related control components are housed. The control system 5 may also include a touch screen display 52, which is connected to the controller and is used to display parameter information and provide a human-machine interface.

[0151] See Figure 1 and Figure 2 The three-layer bursting bead multi-process molding equipment of this embodiment also includes a frame 7, which is provided with a tabletop 71. The curing and molding device 2 is installed on the tabletop 71 of the frame 7. The dripping device 1 is installed on the frame 7 and located above the curing and molding device 2, and also above the tabletop 71. The intermediate layer leather liquid raw material tank 1.5e and the outer layer leather liquid raw material tank 1.6e are both placed on the tabletop 71 and pumped to the dripping device 1 through the intermediate layer leather liquid throat pipe 1.5d and the outer layer leather liquid throat pipe 1.6d, respectively. The visual inspection device 3 is located below the curing and molding device 2 and also below the tabletop 71. The rejection component of the rejection receiving device 4 is installed on one side of the frame 7. The upper end of the discharge bend 4.2 is connected to the lower end of the pagoda bend 3.11 through a pipeline. The oil tank 4.16 is placed on one side of the frame 7 and located below the rejection component. The control system 5 is installed on the frame 7.
