Abstract
Description
Technical Field
[0001] This utility model relates to the field of aerosol processing technology, and in particular to an automatic aerosol glass bead dispensing device. Background Technology
[0002] Aerosols are sealed containers that release liquid in a mist, foam, or spray form using internal pressure. They are widely used in cosmetics, cleaning agents, pharmaceuticals, coatings, and other fields. Before filling, glass beads (usually 1-3 beads, about 2-10mm in diameter) are typically added to the aerosol can. Their main function is to help mix the liquid with the propellant or precipitated components. When shaken, the beads roll or collide, breaking up any clumps and ensuring the contents are homogeneous (e.g., paint, nail polish, some spray adhesives).
[0003] Current production lines generally use rotary feeding devices: glass beads in the storage tank are sorted by vibration and fall from the outlet into a circular track. As the motor-driven rotary table rotates, the receiving holes on its surface periodically align with the track outlet to receive the glass beads. The rotary table transfers the glass beads to a fixed support tray area. Because the rotary table rotates continuously while the support tray is stationary, the glass beads experience sliding friction at their contact surfaces. When the rotary table moves the glass beads to the discharge port of the support tray, the glass beads slide into the discharge tray through an inclined guide groove. At this time, a pushing device pushes the glass beads into the discharge pipe, and finally they fall into the aerosol can that arrives at the bottom of the pipe simultaneously, completing the automatic dispensing.
[0004] The existing equipment lacks the function of screening glass beads by size during the feeding process. Because small-sized glass beads often get mixed in during storage, transportation and production, when smaller glass beads are loaded into the aerosol can, the mixing effect is poor and the suction tube may even be blocked when shaken, making it difficult to meet production requirements. Utility Model Content
[0005] The purpose of this invention is to solve the problem in the prior art that it is inconvenient to screen the size of glass beads when dispensing them into an aerosol, and to propose an automatic glass bead dispensing device for aerosols.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic aerosol glass bead dispensing device includes a rotating box with a feeding section inside. It also includes a storage bin fixedly mounted on the top of the rotating box, wherein a fixing plate is fixedly mounted on one inner wall of the storage bin, and the inner wall of the fixing plate and the inner wall of the storage bin form a waste bin. An installation groove is formed on the fixing plate, and the bottom of the installation groove communicates with the inside of the waste bin. A screening plate is slidably mounted in the installation groove, wherein multiple screening grooves are formed on the screening plate, the bottom of each screening groove communicates with the inside of the waste bin, and guide plates are fixedly mounted on the top of both sides of each screening groove. A sliding channel is formed between the two sets of guide plates, and the two ends of the sliding channel are respectively connected to the output end of the storage bin and the input end of the feeding section.
[0008] To facilitate the sliding of the glass beads, preferably, the fixing plate has an inverted L-shaped structure, the top of the fixing plate is inclined, and the mounting groove is formed on the inclined surface of the fixing plate.
[0009] Preferably, the width of the screening groove is in the range of 0.5-9mm.
[0010] In order to adjust the amount of glass beads fed, preferably, the storage bin is provided with an adjustment plate, one end of which extends into the storage bin and forms a feeding channel with the inner wall of one side of the storage bin. The feeding channel is connected to one end of the sliding channel, and a vibration motor is fixedly installed on the storage bin.
[0011] For convenient material handling, preferably, the feeding unit has a rotating material handling part and a distributing part. The rotating material handling part includes a material support plate detachably disposed in the rotating box. The rotating box has a feeding channel, the top of which is connected to the other end of the sliding channel. A turntable is rotatably disposed in the rotating box, the bottom of which abuts against the top of the material support plate. A groove is formed on the top of the turntable, and the bottom of the feeding channel is connected to the groove. The material support plate has multiple first discharge holes, and multiple second discharge holes corresponding to the first discharge holes are formed on the bottom of the groove. When the axis of the second discharge hole coincides with that of the first discharge hole, at least one glass bead enters the first discharge hole through the second discharge hole.
[0012] Furthermore, the material distribution unit includes a material distribution box disposed at the bottom of the rotating box, the material distribution box having multiple receiving chambers inside, a dispensing pipe with a valve fixedly disposed at the bottom of the receiving chamber, the output end of the dispensing pipe being connected to the mouth of the aerosol can, and multiple conveying pipes fixedly disposed on the rotating box, the two ends of the conveying pipes being connected to the output end of the first discharge hole and the input end of the receiving chamber, respectively.
[0013] Compared with the prior art, the present invention provides an automatic aerosol glass bead dispensing device, which has the following beneficial effects:
[0014] 1. This automatic glass bead dispensing device for aerosols features a screening plate installed inside the storage hopper. The screening plate has elongated screening grooves that extend through one side of the wall. Guide plates are fixedly installed on the top of both sides of the screening grooves. When glass beads enter one end of the sliding channel from the output end of the storage hopper, those of the correct size slide out from the other end of the sliding channel, while those of the incorrect size pass through the screening grooves and enter the waste hopper. This automatic screening of glass beads during the feeding process not only ensures mixing but also prevents them from being sucked into the suction pipe, thus improving the overall performance.
[0015] 2. This automatic glass bead dispensing device for aerosols uses a distribution box fixed at the bottom of the rotating box, and multiple dispensing pipes fixed at the bottom of the distribution box. Glass beads entering the first feeding hole can enter the receiving chamber through the conveying pipe. When the aerosol can moves directly below the dispensing pipe, the valve of the dispensing pipe is opened to dispense glass beads into the aerosol can. Multiple aerosol cans can be dispensed with glass beads at the same time, improving production efficiency.
[0016] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model has a screening plate installed in the storage bin, with a long strip-shaped screening groove that extends through one side of the wall thickness on the screening plate. Guide plates are fixedly installed on the top of both sides of the screening groove. This allows for automatic screening of glass beads by size during the feeding process, which not only ensures the mixing effect but also prevents them from being sucked into the suction tube, thus improving the usage effect.

[0024] Example:
[0025] Reference Figures 1-4An automatic aerosol glass bead dispensing device includes a rotating box 1, a feeding section inside the rotating box 1, and a storage bin 102 fixedly mounted on the top of the rotating box 1. A fixing plate is fixedly mounted on one inner wall of the storage bin 102. A waste bin 105 is formed between the inner wall of the fixing plate and the inner wall of the storage bin 102. To facilitate the automatic discharge of waste from the waste bin 105, a discharge plate is fixedly mounted inside the waste bin 105. Unsuitable glass beads entering the waste bin 105 can be discharged from the waste bin 105 through the discharge plate. An installation groove 104 is provided on the fixing plate. Here, the fixing plate is designed as an inverted L-shaped structure, and the top of the fixing plate... The mounting plate is inclined, with the mounting groove 104 formed on the inclined surface of the fixed plate. When the glass beads fall onto the top of the fixed plate, they can slide along the inclined surface at the top. The bottom of the mounting groove 104 is connected to the waste bin 105. A screening plate 2 is slidably mounted in the mounting groove 104. The mounting groove 104 is a stepped groove, and the end of the mounting groove 104 at the lowest point of the inclined surface is open. Blocks are fixedly installed on the inner walls of both sides of the opening to block the screening plate 2 and prevent it from sliding down from the opening, thus affecting normal use. The screening plate 2 has multiple screening grooves 201, ranging from two to twenty. Here, we prefer eleven. The end of the screening trough 201 near the inclined surface is also open and connects to the opening of the mounting trough 104. When glass beads of the correct size roll on the screening trough 201, it reduces obstruction to the glass beads and improves the usage effect. The bottom of the screening trough 201 is connected to the waste bin 105, meaning that glass beads of the wrong size can fall from the screening trough 201 into the waste bin 105. Guide plates 202 are fixedly installed on the top of both sides of the screening trough 201. The guide plates 202 have a right-angled triangular structure, and the guide plates 202 on two adjacent screening troughs 201 intersect to form a large isosceles triangle. At this time, the two sets of non-intersecting guide plates 202 A sliding channel is formed between the glass beads and the storage bin 102. The two ends of the sliding channel are connected to the output end of the storage bin 102 and the input end of the feeding section, respectively. That is to say, the glass beads enter one end of the sliding channel from the output end of the storage bin 102. During the sliding process, glass beads of the correct size will slide out from the other end of the sliding channel, while glass beads of the incorrect size will enter the waste bin 105 through the screening tank 201. This realizes automatic screening of glass bead size during the feeding process, which not only ensures the mixing effect, but also avoids the situation of being sucked into the suction tube. It also ensures the quality of glass beads in the aerosol can, promotes the production standard of high-end aerosols, and ensures that every aerosol product is completely consistent.
[0026] In use, a screening plate 2 is installed in the storage bin 102. The screening plate 2 has a long strip-shaped screening groove 201 that extends through one side of the wall thickness. Guide plates 202 are fixedly installed on the top of both sides of the screening groove 201. When the glass beads enter one end of the sliding channel from the output end of the storage bin 102, the glass beads that meet the size will slide out from the other end of the sliding channel, while the glass beads that do not meet the size will pass through the screening groove 201 and enter the waste bin 105. This realizes automatic screening of the size of the glass beads during the feeding process, which not only ensures the mixing effect, but also avoids the situation of being sucked into the suction tube, thus improving the use effect.
[0027] Reference Figure 4 The width of the screening groove 201 ranges from 0.5 to 9 mm. Here, we prefer 7 mm (-0.1, -0.3 mm). At this time, the size of the glass beads is 8 ± 1 mm. During use, the screening plate 2 is slidably placed in the installation groove 104. The corresponding screening plate 2 can be replaced according to the size of the glass beads used to improve the usage effect.
[0028] Reference Figures 1-3 An adjusting plate 103 is provided on the storage silo 102, and an adjusting screw is threadedly connected to the storage silo 102. One end of the adjusting screw abuts against the side wall of the adjusting plate 103, which is used to fix the adjusting plate 103 after the position of the adjusting plate 103 is adjusted. One end of the adjusting plate 103 extending into the storage silo 102 forms a feeding channel with one side inner wall of the storage silo 102, and the feeding channel is connected to one end of the sliding channel. A vibration motor, model XP1688-main 3, is fixedly installed on the storage silo 102. In use, by sliding the adjusting plate 103 on the storage silo 102 and adjusting the size of the feeding channel, the feeding speed and quantity of glass beads can be controlled, which is convenient for the screening plate 2 to screen. Moreover, the vibration motor installed on the storage silo 102 can further improve the feeding effect.
[0029] Reference Figures 1-3Here, the feeding section has a rotating material handling section and a distributing section. The rotating material handling section includes a material support tray 3 detachably installed inside the rotating box 1. Preferably, the material support tray 3 is bolted to the rotating box 1. A maintenance window, larger than half the size of the rotating box 1, is provided on the side wall of the rotating box 1. A maintenance cover is bolted to the maintenance window to facilitate the replacement or maintenance of components inside the rotating box 1, improving performance. A feeding channel is provided inside the rotating box 1, connecting the top of the feeding channel to the other end of the sliding channel. This means that when glass beads of the correct size slide out from the other end of the sliding channel, they will... Inside the feeding channel, a turntable 4 is rotatably mounted inside the rotating box 1, and a rotating shaft 6 is also rotatably mounted inside the rotating box 1. A support plate 601 is fixedly mounted on the top of the rotating shaft 6, with the top of the support plate 601 abutting against the bottom of the turntable 4. A polygonal guide block 602 (preferably rectangular) is fixedly mounted on the top of the support plate 601. A guide groove is formed at the bottom of the turntable 4, and the guide block 602 slides within the guide groove. When the rotating shaft 6 rotates, the turntable 4 can be driven to rotate via the guide block 602. A servo motor for driving the rotation of the rotating shaft 6 is fixedly mounted inside the rotating box 1. The rotating box 1 has a ventilation opening at its bottom. A first magnetic block is fixedly mounted on the top of the support plate 601, and a second magnetic block, magnetically attracted to the first magnetic block, is fixedly mounted on the bottom of the turntable 4. This ensures a good fit between the bottom of the turntable 4 and the top of the support plate 601. The top of the support plate 601 is flush with the top of the material tray 3. The bottom of the turntable 4 can be aligned with the top of the material tray 3, or they can be left apart. When not aligned, the distance between the bottom of the turntable 4 and the top of the material tray 3 is less than the radius of the glass bead. A groove is formed on the top of the turntable 4, with an approximately V-shaped cross-section, extending one side towards the axis of the turntable 4. On the other side, it extends towards the circumference of the turntable 4, connecting with the groove at the bottom of the feeding channel. The material tray 3 has multiple first feeding holes 301, ranging from two to twenty. Here, we prefer eight, evenly distributed circumferentially. The bottom of the groove has multiple second feeding holes 401 corresponding to the first feeding holes 301, also eight in number. The inner diameters of the first feeding holes 301 and the second feeding holes 401 are equal, and the inner diameter of the second feeding holes 401 is greater than or equal to the diameter of the glass bead. Here, we prefer 9+0.The glass beads are 3mm thick. A groove is provided on the turntable 4 to facilitate the entry of glass beads into the second feeding hole 401. During the rotation of the turntable 4, when the axis of the second feeding hole 401 coincides with that of the first feeding hole 301, at least one glass bead passes through the second feeding hole 401 and enters the first feeding hole 301. Preferably, two glass beads are used. At this point, the depth of the second feeding hole 401 is less than the sum of the diameters of the two glass beads. That is, the bottom glass bead is completely inside the second feeding hole 401, and a large portion of the second glass bead is inside the second feeding hole 401. When the axis of the second feeding hole 401 coincides with that of the first feeding hole 301, the turntable 4 pauses briefly, allowing both glass beads to enter the first feeding hole 301, achieving the desired material handling effect.
[0030] Reference Figure 2 Here, the material distribution section includes a material distribution box 5 at the bottom of the rotating box 1. Connecting plates are fixed at both ends of the material distribution box 5, and these connecting plates are bolted to the bottom of the rotating box 1. The material distribution box 5 contains multiple receiving chambers 501, arranged in two groups of four chambers each, for a total of eight chambers 501. A dispensing pipe 502 with a valve (preferably a solenoid valve) is fixed at the bottom of each receiving chamber 501. The output end of the dispensing pipe 502 is connected to the opening of the aerosol can. In use, the conveyor belt drives two groups of aerosol cans to move directly below the dispensing pipe 502, and then the valve on the dispensing pipe 502 is opened to dispense glass beads into the aerosol cans. Multiple conveying pipes 101 are fixedly installed on the rotating box 1, ranging from two to twenty. Here, we prefer eight pipes, each corresponding to a first discharge hole 301. The two ends of each conveying pipe 101 are connected to the output end of the first discharge hole 301 and the receiving chamber 501, respectively. The input terminal is connected. During use, glass beads entering the first feeding hole 301 can enter the receiving chamber 501 through the conveying pipe 101. When the aerosol can moves directly below the dispensing pipe 502, the valve of the dispensing pipe 502 is opened to dispense glass beads into the aerosol can. Multiple aerosol cans can be dispensed simultaneously, improving production efficiency. The dispensing box 5 is a transparent acrylic plate with 8 sets of bead holes arranged in it, corresponding one-to-one with the receiving chamber 501. Each bead hole corresponds to a set of dual-color indicator lights (green light indicates normal filling, red light indicates empty state). Sensors for monitoring glass beads are installed in the dispensing pipe 502, such as ultrasonic sensors, photoelectric sensors, and capacitive sensors. Photoelectric sensors are suitable for monitoring opaque glass beads. When the glass beads are transparent, ultrasonic sensors are preferred, model UB400-12GM-E5-V1, which can monitor the glass beads in the dispensing pipe 502 in real time and reduce the occurrence of missing beads.
