[0002] Bursting beads, also known as flavor pills, brittle capsules, and beads, refer to small liquid beads embedded in the tobacco filter. They are wrapped with liquids of different types of flavors. Smokers can pinch the beads to burst during smoking to make the liquid inside the beads flow out, making the cigarette taste richer and more fragrant, giving smokers a more comfortable experience.

[0003] The existing popping bead box includes a bottom cover, a top cover, a desiccant and popping beads. A certain amount of popping beads and desiccant need to be loaded into the bottom cover and sealed by the top cover. However, the existing popping beads are usually only filled for a single flavor to achieve quantitative packaging. Considering the user's demand for popping beads with multiple flavors, the current popping bead box production equipment is difficult to meet the needs. Moreover, when the popping bead plate is screened, the popping beads are exposed and directly in contact with the outside air, and the popping beads are easily affected by moisture.

[0016] S2. Start one or more of the popping bead discs of the popping bead screening mechanism at the same time, which are controlled by a controller. Before the popping bead screening, it is necessary to manually put popping beads of different flavors into each popping bead disc in advance, and the popping bead disc opening and closing are realized by the closing component. When the top rod lifting component closes the jack, the air source is connected to the drying chamber, and the draining disc rotates to make the popping beads do centrifugal motion.

[0019] In summary, the beneficial effects of the present invention are as follows: the existing bead popping equipment only packages single-flavor bead popping, and is not dried before packaging, so the moisture of the bead popping affects its service life. The bead popping screening mechanism of the present invention includes multiple bead popping trays, which can be operated simultaneously or only one of them can be operated. The parameters are set according to the needs and controlled by the control unit. A certain amount of bead popping is placed in the bead popping tray according to production needs. The cover is driven by the third driving cylinder and moves up and down with the mobile bracket to realize the opening and closing of the bead popping tray, so as to prevent the bead popping from getting damp. The bead popping into the bead popping tray rotates with the draining tray and is connected to hot air (the temperature needs to be controlled to prevent the bead popping from melting) for drying. Within the set time, the bead popping reaches the optimal drying state after centrifugal motion and air drying. Then the first driving cylinder drives the through The gas rod descends and separates from the socket, and the popping beads flow out of the socket through the conical surface of the drain plate and enter the sieving cavity. Since the sieving plate is tilted, the popping beads will be in a lower position, and some of the popping beads will enter the dropping holes. When the sieving plate with the dropping holes of the popping beads rotates to a higher position, the popping beads in the dropping holes will flow out from the discharge holes on the inclined plate, flow to the suction box through the hose, and finally be transported to the bottom cover by the material receiving assembly. The present invention provides a drying and sieving structure in the popping bead plate to process batches of popping beads and realize quantitative packaging. At the same time, it can combine popping beads of multiple flavors according to demand without manual labor or multiple equipment for processing, and can dry popping beads of multiple flavors without batch drying like traditional drying equipment. It has a high degree of automation, which makes up for the shortcomings of existing popping bead box assembly equipment. BRIEF DESCRIPTION OF THE DRAWINGS

The screening chamber 312 is provided with a useful The push rod lifting assembly 315 is used to open and close the socket 3141. The push rod lifting assembly 315 is connected to an air source. When the push rod lifting assembly 315 closes the socket 3141, the air source is connected to the drying chamber 311. A one-way air valve 317 is provided on the cover 351. The connected air source can flow from the one-way air valve 317 to the outside to achieve air exchange. The one-way air valve 317 is commercially available. In this embodiment, a support ring is provided under the drain tray, and the drain tray can be driven by a motor.

[0033] A conical surface 3142 with a larger upper portion and a smaller lower portion is provided at the bottom of the drain tray 314, and the socket 3141 is provided at the center of the bottom of the conical surface 3142. The top rod lifting assembly 315 includes a ventilation rod 3151, a first driving cylinder 3152, and a support frame 3153. The first driving cylinder 3152 is installed at the center of the support frame 3153 and the output end of the first driving cylinder 3152 is connected to the ventilation rod 3151. A ventilation cavity is provided in the ventilation rod 3151 and a plurality of ventilation holes 3154 are evenly distributed on the outer wall of the ventilation rod 3151. The side wall of the ventilation pipe 3155 is connected to the ventilation pipe 3155 and the ventilation pipe 3155 is connected to the air source. The support frame 3153 in this example is a triangular support frame 3153, and space is left between adjacent supporting legs for the bursting beads to pass through.

[0034] The sub-screening disc 313 is installed obliquely in the sub-screening cavity 312, and an oblique ring 3121 is provided at the bottom of the sub-screening disc 313 in the sub-screening cavity 312.

When the sealing cover 351 moves up, the connecting shaft 352 is separated from the plug-in part 316 by external force. The preferred method is that the upper end opening of the blasting bead tray 31 is completely closed when the sealing cover 351 is docked with the drain tray. Of course, the incomplete sealing does not affect the drying of the drying chamber 311. It is sufficient to try to avoid most of the blasting beads being exposed to the air.

The linear drive cylinder 342 is installed on the connecting arm 344 and is used to drive the material receiving valve 341 to move along the front and rear direction of the turntable 1. The vertical drive cylinder 343 is installed on the column 32 and is used to drive the connecting arm 344 to move along the vertical direction.

[0039] A baffle 12 is provided outside each placement slot 11 , and a contact sensor 345 is provided on the side wall of the material receiving valve 341 . When the contact sensor 345 of the material receiving valve 341 touches the baffle 12 , the valve port of the material receiving valve 341 opens.

[0040] The bottom cover feeding mechanism 2 includes a bottom cover vibration plate 21 and a bottom cover feeding robot 22 ; the desiccant feeding mechanism 4 includes a desiccant vibration plate 41 and a desiccant feeding robot 42 ; the top cover feeding mechanism 5 includes a top cover vibration plate 51 and a top cover feeding robot 52 .

[0041] The assembly method using the bead box assembly equipment includes the following steps:

[0042] S1, the bottom cover feeding mechanism 2 moves the bottom covers one by one into the placement slot 11, and the power source drives the turntable 1 to rotate, so that the bottom covers reach the bead blasting screening mechanism 3;

[0043] S2. Start one or more of the popping bead trays 31 of the popping bead screening mechanism 3 at the same time, which are controlled by the controller. Before the popping bead screening, it is necessary to manually put popping beads of different flavors into each popping bead tray 31 in advance, and the opening and closing of the popping bead tray 31 are realized by the closing component 35. When the push rod lifting component 315 closes the socket 3141, the air source is connected to the drying chamber 311, and the draining tray 314 rotates to make the popping beads perform centrifugal motion. After the popping beads are air-dried and centrifuged within the set time, the push rod lifting component 315 opens the socket 3141 of the draining tray 314, and the popping beads flow to the screening tray 313 for quantitative screening, and then flow to the suction component 33 through the hose 37, and finally are transferred to the bottom cover by the receiving component 34. The turntable 1 rotates to rotate the bottom cover filled with popping beads to the desiccant feeding mechanism 4;

[0044] S3, the desiccant feeding mechanism 4 moves the desiccant into the bottom cover filled with explosive beads, and the power source drives the turntable 1 to rotate so that it reaches the top cover feeding mechanism 5;

[0045] S4, the top cover loading mechanism 5 moves the top cover to above the bottom cover, seals the bottom cover and the top cover, and finally realizes the unloading of the finished bead box.

[0046] Working principle: the existing bead popping equipment only packages single flavor bead popping, and is not dried before packaging. The moisture of the bead popping affects its service life. The bead popping screening mechanism 3 of the present invention includes multiple bead popping trays 31, which can be operated simultaneously or only one of them is operated. The parameters are set according to the needs and controlled by the control unit. A certain amount of bead popping is placed in the bead popping tray 31 according to the production needs. The cover 351 is driven by the third driving cylinder 353 and moves up and down with the movable bracket 38 to realize the opening and closing of the bead popping tray 31 to prevent the bead popping from getting damp. The bead popping into the bead popping tray 31 rotates with the draining tray 314 and is connected to hot air (the temperature needs to be controlled to prevent the bead popping from melting) for drying. After the set time, the bead popping reaches the optimal drying state after centrifugal motion and air drying. Then the first driving cylinder 3152 drives the ventilation rod 3151 to descend and separate from the socket 3141, and the bead popping is completed. The beads flow out of the insertion hole 3141 through the conical surface 3142 of the drain plate 314 and enter the sieve cavity 312. Since the sieve plate 313 is tilted, the beads will be in a lower position, and some of the beads will enter the drop holes 3131. When the drop holes 3131 of the sieve plate 313 with the beads rotate to a higher position, the beads in the drop holes 3131 will flow out from the discharge holes 3123 on the inclined plate, flow to the suction box 331 through the hose 37, and finally be transported to the bottom cover by the material receiving assembly 34. The present invention provides a drying and sieving structure in the bead blasting plate 31 to process batches of beads and realize quantitative packaging. At the same time, beads of multiple flavors can be combined according to demand without manual labor or multiple equipment for processing, and can dry beads of multiple flavors without batch drying like traditional drying equipment. It has a high degree of automation, which makes up for the shortcomings of existing bead box assembly equipment.
