Description

Technical Field

[0001] This invention belongs to the field of glitter powder processing technology and relates to a drying device for processing glitter powder. Background Technology

[0002] New material glitter powder refers to glitter or sequins made using novel materials or technologies, offering better environmental friendliness, safety, or unique visual effects. With continuous technological advancements, the application of glitter powder in various fields will become increasingly widespread. During the production and processing of glitter powder, the moisture content directly determines its performance, safety, and subsequent processing, necessitating a drying process.

[0003] Glitter powder is usually dried in a drying oven. Because glitter powder is very fine, it easily adheres to the inner wall of the drying device. Discharging requires scraping with tools, which makes the process cumbersome and reduces the production efficiency of glitter powder.

[0004] To address the above problems, this invention proposes a drying device for processing glitter powder. Summary of the Invention

[0005] To address the problems existing in the background technology, the present invention proposes a drying device for processing glitter powder.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A drying device for processing glitter powder, comprising a drying box, wherein a column is rotatably installed inside the drying box; multiple material-holding cylinder mechanisms are arranged along the circumferential direction on the column; each material-holding cylinder mechanism includes a connecting block, an arc-shaped perforated plate, and a first closing plate; there are two connecting blocks, each of which is fixedly connected to an arc-shaped perforated plate, the arc-shaped perforated plate being elastically slidably connected to the other connecting block, and one side of the first closing plate being rotatably connected to one of the arc-shaped perforated plates; the connecting blocks are connected to limit blocks via telescopic rods, and the limit blocks are slidably arranged on the column. The drying chamber is equipped with a drive unit that moves the limiting block outward. A discharge pipe is located at the bottom of the drying chamber, and a discharge assembly is elastically slidably installed within the discharge pipe. When the glitter powder in the holding cylinder mechanism is dried and moves above the discharge assembly, the drive unit moves the limiting block outward from the limiting groove and separates it from the column. Under its own gravity, the holding cylinder mechanism partially enters the discharge pipe, the discharge assembly opens, the first closing plate opens, and the glitter powder in the holding cylinder mechanism falls out. The column continues to rotate, and under the action of other holding cylinder mechanisms, the holding cylinder mechanism in the discharge pipe shakes up and down, shaking off the glitter powder from the inner wall of the holding cylinder mechanism in the discharge pipe.

[0007] Furthermore, the discharge assembly includes a first spiral plate, a second spiral plate, and a second closing plate; the first spiral plate is elastically slidably disposed inside the discharge pipe, the second spiral plate is disposed on the first spiral plate, the second spiral plate is rotatably connected to the second closing plate, and a fourth motor for driving the second closing plate to rotate is disposed on the second spiral plate.

[0008] Furthermore, a groove is provided on the inner wall of the discharge pipe, and a slider is slidably disposed in the groove. The slider is fixedly connected to the first spiral plate. A second spring is provided in the groove, the upper end of the second spring is connected to the slider, and the lower end of the second spring is fixedly connected to the end wall of the groove. An electrically controlled telescopic push rod is installed in the groove, which is used to lift the slider.

[0009] Furthermore, the discharge assembly is equipped with a weighing component. When the material container mechanism moves above the discharge assembly, the weighing component weighs the material container mechanism. When the weight of the material container mechanism is less than a preset value, the drive component is activated.

[0010] The weighing component includes a pressure sensor, which is disposed between the first and second spiral plates. When the material container mechanism is on the discharge component, the material container mechanism acts on the pressure sensor through the second spiral plate, causing the pressure sensor to generate a pressure value.

[0011] Furthermore, the driving component includes an electromagnet, and a fixed limiting slide is fixed inside the drying oven. The fixed limiting slide has a clearance groove that cooperates with the limiting block. The electromagnet is disposed in the clearance groove. When the electromagnet is energized, it has an attractive force on the limiting block.

[0012] Furthermore, the drying chamber is equipped with a perforated plate for dispersing, and the material holding cylinder mechanism is located inside the perforated plate for dispersing.

[0013] Furthermore, a feeding assembly is provided on the top of the drying chamber, the feeding assembly includes a feeding pipe, the feeding pipe is located on the top of the drying chamber, a guide plate is provided inside the feeding pipe, and a cover plate is provided on the feeding pipe.

[0014] Furthermore, a stirring rod is provided inside the material container mechanism. The stirring rod is rotatably positioned between two connecting blocks, and a second motor for driving the stirring rod to rotate is installed on one of the connecting blocks.

[0015] Furthermore, a rubber strip is provided on the side of the second closing plate away from the second loop plate.

[0016] Furthermore, a T-shaped groove is provided on the connecting block, and a T-shaped slider is slidably disposed in the T-shaped groove. The T-shaped slider is fixedly connected to the corresponding arc-shaped perforated plate, and a first spring is fixedly connected between the end wall of the T-shaped slider and the T-shaped groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Once the glitter powder in the feeding cylinder is dried, it detaches from the column and enters the discharge pipe for discharge. During the discharge process, other feeding cylinders rotating around the column continue drying, sequentially squeezing the feeding cylinder in the discharge pipe. This causes the feeding cylinder in the discharge pipe to vibrate up and down, which helps to remove the glitter powder from its inner wall, improving the glitter powder recovery rate. Furthermore, no additional structure is needed to scrape the glitter powder from the inner wall of the feeding cylinder, and it does not affect the drying process of other feeding cylinders, thus contributing to improved glitter powder drying efficiency.

[0019] As the feeding cylinder rotates around the column, the glitter powder inside the feeding cylinder tumbles, ensuring that the glitter powder is heated evenly, which helps to improve drying efficiency. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1: As Figures 1-18 As shown, the technical solution adopted by the present invention is as follows: A drying device for processing glitter powder includes a drying box 1, a material holding cylinder mechanism 7, a feeding component and a discharging component.

[0041] A column 3 is rotatably mounted inside the drying chamber 1, and the column 3 is coaxially mounted with the drying chamber 1. A first motor 2 is fixedly mounted on the drying chamber 1 to drive the column 3 to rotate.

[0042] like Figure 7 As shown, multiple material-holding cylinder mechanisms 7 are evenly arranged along the circumference of the column 3. The material-holding cylinder mechanism 7 is used to hold glitter powder.

[0043] Each material container mechanism 7 includes a connecting block 8, an arc-shaped perforated plate 9, and a first closing plate 15. There are two connecting blocks 8, located at opposite ends of the material container mechanism 7. Each connecting block 8 is fixedly connected to an arc-shaped perforated plate 9; one end of the arc-shaped perforated plate 9 is fixedly connected to the corresponding connecting block 8, and the other end of the arc-shaped perforated plate 9 is elastically slidably connected to the other connecting block 8. Specifically, as shown... Figure 11 As shown, a T-shaped groove 10 is provided on the connecting block 8, and the length direction of the T-shaped groove 10 is parallel to the axis direction of the material container mechanism 7. A T-shaped slider 11 is fixedly connected to the arc-shaped perforated plate 9, and the T-shaped slider 11 is slidably disposed in the T-shaped groove 10. A first spring 12 is provided in the T-shaped groove 10, and the first spring 12 is fixedly connected between the T-shaped slider 11 and one end wall of the T-shaped groove 10.

[0044] like Figure 12 , Figure 14 As shown, the connecting block 8 has a mating groove that mates with the arc-shaped perforated plate 9. One end of the arc-shaped perforated plate 9, on which the T-shaped slider 11 is mounted, is slidably positioned within the mating groove. Under the action of the first spring 12, the T-shaped slider 11 is positioned at the end of the T-shaped groove 10 furthest from the other connecting block 8, at which point the material-holding cylinder mechanism 7 is in its shortest state. When the T-shaped slider 11 moves along the T-shaped groove 10 toward the other connecting block 8, the two connecting blocks 8 move away from each other, the material-holding cylinder mechanism 7 extends, and the arc-shaped perforated plate 9 slides along the mating groove.

[0045] Each connecting block 8 is fixedly connected to a telescopic rod 6, the axis of which is perpendicular to the axis of the material container mechanism 7. A limiting block 5 is fixedly connected to the end of the telescopic rod 6 away from the material container mechanism 7. The limiting block 5 is slidably disposed within a limiting groove 4 formed on the column 3. As the limiting block 5 slides outward along the limiting groove 4, the two connecting blocks 8 move away from each other, the material container mechanism 7 extends, the limiting block 5 disengages from the limiting groove 4, and the material container mechanism 7 detaches from the column 3.

[0046] The drying oven 1 is equipped with a driving component that moves the limiting block 5 outward. When the driving component is activated, the limiting block 5 moves outward from the limiting groove 4 and disengages from the column 3. Figure 3 , Figure 16As shown, the driving component includes an electromagnet 19, and a fixed limiting slide 18 is fixed inside the drying oven 1. The fixed limiting slide 18 has a relief groove that cooperates with the limiting block 5. The electromagnet 19 is set in the relief groove. When the electromagnet 19 is energized, it has an attractive force on the limiting block 5.

[0047] like Figure 10 As shown, one side of the first closing plate 15 is rotatably connected to one of the arc-shaped perforated plates 9 via a first rotating shaft 16. A third motor 17 that drives the first rotating shaft 16 to rotate is installed on the corresponding connecting block 8. The connecting block 8, the arc-shaped perforated plate 9, and the first closing plate 15 form a space for holding glitter powder. The first closing plate 15 is located on the side of the material holding cylinder mechanism 7 away from the column 3.

[0048] A stirring rod 14 is rotatably mounted inside the material container mechanism 7. A second motor 13 is installed on one of the connecting blocks 8, and the output shaft of the second motor 13 is fixedly connected to one end of the stirring rod 14. The stirring rod 14 rotates inside the material container mechanism 7, thereby agitating the glitter powder, which helps to improve the drying efficiency of the glitter powder and ensures that the glitter powder is heated evenly.

[0049] An air inlet pipe 36 is provided on one side of the drying chamber 1, and an exhaust pipe 37 is provided on the other side. Hot air is delivered into the drying chamber 1 through the air inlet pipe 36 to dry the glitter powder. The gas inside the drying chamber 1 is discharged through the exhaust pipe 37.

[0050] like Figure 4 As shown, a perforated plate 35 is fixedly installed inside the drying chamber 1, and the material holding cylinder mechanism 7 is located inside the perforated plate 35. The perforated plate 35 has a dispersing effect on the hot air, so that the hot air is evenly dispersed into the drying chamber 1.

[0051] A feeding assembly is provided at the top of the drying chamber 1. The feeding assembly includes a feeding pipe 20, which is fixed to the top of the drying chamber 1 and passes through a perforated plate 35 of the dispersion belt into the drying chamber 1. A cover plate 22 is installed on the upper part of the feeding pipe 20. Two guide plates 21 are symmetrically arranged inside the feeding pipe 20. The upper ends of the two guide plates 21 are far apart from each other.

[0052] Rotate the feeding cylinder mechanism 7 to the top of the drying chamber 1, positioning it below the feed pipe 20. At this point, start the third motor 17. The third motor 17 drives the first closing plate 15 to rotate via the first rotating shaft 16, opening the feeding cylinder mechanism 7. Then, open the cover plate 22 and add glitter powder into the feeding cylinder mechanism 7 through the feed pipe 20. After adding the powder, rotate the first closing plate 15 via the third motor 17, closing the feeding cylinder mechanism 7. Rotate the column 3, causing the next feeding cylinder mechanism 7 to rotate to the top of the drying chamber 1 and add glitter powder. This process continues until all feeding cylinder mechanisms 7 have added glitter powder.

[0053] A discharge pipe 23 is installed at the bottom of the drying chamber 1, and the discharge pipe 23 extends upward through the perforated plate 35 of the dispersion belt. A discharge assembly is installed inside the discharge pipe 23.

[0054] The discharge assembly includes a first spiral plate 24, a second spiral plate 25, and a second closing plate 27. The first spiral plate 24 is elastically slidably disposed within the discharge pipe 23. Specifically, as shown... Figure 3 , Figure 5 As shown, grooves 32 are provided on the inner walls of both ends of the discharge pipe 23, and sliders 31 are slidably disposed in the grooves 32. The sliders 31 are fixedly connected to the first spiral plate 24. A second spring 33 is provided in the grooves 32, the upper end of the second spring 33 is connected to the slider 31, and the lower end of the second spring 33 is fixedly connected to the end wall of the groove 32.

[0055] An electrically controlled telescopic push rod 34 is installed inside the slide 32. The electrically controlled telescopic push rod 34 is used to lift the slider 31. When the electrically controlled telescopic push rod 34 extends, it pushes the first spiral plate 24 upward through the slider 31.

[0056] A second circular plate 25 is provided on the first circular plate 24. The side of the second circular plate 25 closest to the axis of the drying chamber 1 is arc-shaped and matches the perforated plate 35 of the dispersion zone. Under the support of the electrically controlled telescopic top rod 34, when the slider 31 is at the upper end of the slide groove 32, the second circular plate 25 is flush with the inner wall of the perforated plate 35 of the dispersion zone.

[0057] Two second closing plates 27 are symmetrically arranged inside the second circular plate 25. The second closing plates 27 are rotatably connected to the second circular plate 25 via a second rotating shaft 29, and the second closing plates 27 are fixedly connected to the second rotating shaft 29. The second rotating shaft 29 is rotatably connected to the second circular plate 25. The second closing plates 27 are arc-shaped to match the second circular plate 25. A fourth motor 30 is installed on the second circular plate 25 to drive the second rotating shaft 29 to rotate. The fourth motor 30 drives the second rotating shaft 29 to rotate, and the second closing plates 27 rotate around the second rotating shaft 29, causing the discharge assembly to open or close. When the material container mechanism 7 is inside the discharge pipe 23, the discharge assembly opens, opening the first closing plate 15, and the dried glitter powder inside the material container mechanism 7 falls through the discharge assembly.

[0058] Rubber strips 28 are provided on the side of the two second closing plates 27 that are close to each other.

[0059] In this embodiment, a weighing component is provided on the discharge assembly. When the material container 7 passes through the discharge assembly, the weighing component weighs the material container 7. When the weight of the material container 7 is less than a preset value, the electromagnet 19 is energized.

[0060] The weighing assembly includes a pressure sensor 26, which is positioned between the first rotary plate 24 and the second rotary plate 25. Since the discharge assembly is located at the bottom of the drying chamber 1, when the feeding cylinder mechanism 7 moves to the bottom of the drying chamber 1, it tends to move downwards under its own gravity. As the feeding cylinder mechanism 7 passes the discharge assembly, it presses against the pressure sensor 26 through the second rotary plate 25, causing the pressure sensor 26 to generate a pressure value. As drying progresses, the moisture in the glitter powder gradually evaporates, causing the weight of the glitter powder to gradually decrease. Consequently, the pressure exerted by the feeding cylinder mechanism 7 on the second rotary plate 25 gradually decreases, and the pressure value of the pressure sensor 26 gradually decreases. When the glitter powder is dried to a certain extent, the pressure value of the pressure sensor 26 is less than a preset value.

[0061] The first motor 2, electromagnet 19, electrically controlled telescopic rod 34, third motor 17, fourth motor 30, and pressure sensor 26 are all electrically connected to the controller. When the pressure value of pressure sensor 26 is less than the preset value, electromagnet 19 is energized, and electrically controlled telescopic rod 34 shortens.

[0062] Working principle: Initially, the limiting block 5 is in the limiting groove 4, and the telescopic rod 6 is in its shortest state. The first closing plate 15 is in the closed state. Under the action of the first spring 12, the T-shaped slider 11 is at the end of the corresponding T-shaped slide groove 10 away from the other connecting block 8, and the material container mechanism 7 is in its shortest state. The electrically controlled telescopic push rod 34 remains in the extended state, and the electrically controlled telescopic push rod 34 pushes the slider 31 so that the slider 31 is at the upper end of the slide groove 32, so that the second circular plate 25 and the second closing plate 27 are flush with the inner wall of the dispersion perforated plate 35. The second closing plate 27 is in the closed state.

[0063] When using, first add a certain amount of glitter powder to be dried into the feeding cylinder 7. The specific operation is as follows:

[0064] Open cover 22. Start the first motor 2. The first motor 2 drives the column 3 to rotate. The column 3 drives the material container mechanism 7 to rotate through the limit block 5 and the telescopic rod 6. When the material container mechanism 7 moves to the top of the drying chamber 1, the material container mechanism 7 is below the feed pipe 20. At this time, the first closing plate 15 is directly opposite the guide plate 21. Pause the first motor 2 and start the third motor 17 to open the first closing plate 15. Add a measured amount of glitter powder into cover 22. The glitter powder enters the material container mechanism 7 below. Then, close the first closing plate 15 through the third motor 17. Continue to rotate the first motor 2 so that the next material container mechanism 7 is below the guide plate 21.

[0065] Similarly, a fixed amount of glitter powder is added to each of the multiple feeding cylinder mechanisms 7. The cover plate 22 is then placed on top to cover the feed pipe 20.

[0066] It should be noted that the diameter of the holes on the curved perforated plate 9 is smaller than the outer diameter of the glitter powder to prevent the glitter powder from leaking out.

[0067] Next, the glitter powder in the feeding cylinder mechanism 7 is dried. Hot air is delivered into the drying chamber 1 through the air inlet pipe 36. The perforated plate 35 disperses the hot air, ensuring that it enters the drying chamber 1 evenly. The hot air enters the feeding cylinder mechanism 7 through the arc-shaped perforated plate 9 to dry the glitter powder. The gas in the drying chamber 1 is discharged through the exhaust pipe 37.

[0068] Simultaneously, the first motor 2 is started, which drives the column 3 to rotate, and the feeding cylinder mechanism 7 rotates around the column 3. As the feeding cylinder mechanism 7 rotates, the glitter powder tumbles inside the feeding cylinder mechanism 7, which helps to improve drying efficiency and ensures that the glitter powder is heated evenly.

[0069] At the same time, the second motor 13 is started, which drives the stirring rod 14 to rotate. The stirring rod 14 stirs the glitter powder in the material container 7, preventing the glitter powder from accumulating in the material container 7, further improving the drying efficiency, and also helping to make the glitter powder heat evenly.

[0070] As the material-holding cylinder mechanism 7 rotates around the column 3, when it reaches the bottom of the drying chamber 1, it tends to move downwards under its own weight. When it passes the discharge assembly, the mechanism compresses the pressure sensor 26 via the second rotary plate 25, causing the sensor to generate a pressure value. The pressure sensor 26 transmits this value to the controller, which then determines whether the received pressure value is less than a preset value.

[0071] As the drying process continues, the moisture in the glitter powder gradually evaporates, causing the weight of the glitter powder to gradually decrease. Consequently, the extrusion pressure exerted by the feeding cylinder mechanism 7 on the second rotary plate 25 gradually decreases, and the pressure value of the pressure sensor 26 gradually decreases. When the glitter powder is dried to a certain extent, the pressure value of the pressure sensor 26 is less than the preset value.

[0072] When the pressure value of pressure sensor 26 is less than the preset value, the first motor 2 stops, the electromagnet 19 is energized, and the electrically controlled telescopic rod 34 shortens. The first motor 2 stops, causing the column 3 to stop rotating. At this time, the material container mechanism 7 is above the two second closed plates 27, and the limiting block 5 is directly opposite the electromagnet 19. In this embodiment, for ease of description, the material container mechanism 7, which is on the discharge assembly at this time, is named the first material container mechanism.

[0073] When the electromagnet 19 is energized, the limiting block 5 moves into the clearance groove and disengages from the limiting groove 4. The limiting block 5 moves the connecting block 8 via the telescopic rod 6, causing the two connecting blocks 8 to move away from each other, and the two arc-shaped perforated plates 9 to move away from each other. The first material container mechanism extends, the T-shaped slider 11 slides within the T-shaped groove 10, and the first spring 12 is compressed. This continues until the limiting block 5 is attracted to the electromagnet 19, at which point the material container mechanism 7 disengages from the column 3.

[0074] After the electrically controlled telescopic top rod 34 is shortened, the slider 31 loses the support of the electrically controlled telescopic top rod 34, the first material-holding cylinder mechanism and the discharge assembly move downwards, the slider 31 moves down along the slide groove 32, and the second spring 33 is compressed. As the second spring 33 is compressed, the elastic force of the second spring 33 gradually increases. Until the action of the second spring 33, the first material-holding cylinder mechanism, the first rotary plate 24 and the second rotary plate 25 stop moving downwards. At this time, the upper part of the first material-holding cylinder mechanism is located inside the drying chamber 1, as shown. Figure 18 As shown.

[0075] The fourth motor 30 and the third motor 17 are started. The fourth motor 30 drives the second closing plate 27 to rotate via the second rotating shaft 29, thereby opening the discharge assembly. At the same time, the third motor 17 drives the first closing plate 15 to rotate, thereby opening the first material holding cylinder mechanism and discharging the glitter powder inside. A collector is placed below the discharge pipe 23 to collect the dried glitter powder.

[0076] Then, the first motor 2 causes the column 3 to continue rotating, which in turn drives the material container mechanism 7 (excluding the first material container mechanism) to rotate. This continues to dry the glitter powder within the material container mechanism 7. Since the first material container mechanism has been detached from the column 3, it remains within the discharge pipe 23.

[0077] As the column 3 rotates, when the material-holding cylinder mechanism 7 passes the bottom of the drying chamber 1, since the upper part of the first material-holding cylinder mechanism is located inside the drying chamber 1, the material-holding cylinder mechanism 7 will squeeze the first material-holding cylinder mechanism, causing the first material-holding cylinder mechanism to move downwards. The first loop plate 24, the second loop plate 25, and the slider 31 also move downwards, and the second spring 33 is further compressed. As the material-holding cylinder mechanism 7 disengages from the first material-holding cylinder mechanism, under the action of the second spring 33, the slider 31, the first loop plate 24, the second loop plate 25, and the first material-holding cylinder mechanism move upwards.

[0078] As multiple material-collecting cylinder mechanisms 7 pass through the first material-collecting cylinder mechanism in sequence, the first material-collecting cylinder mechanism moves up and down repeatedly, creating a shaking effect. This helps to shake off the glitter powder adhering to the inner wall of the arc-shaped perforated plate 9, allowing the glitter powder to fall smoothly and improving the recovery rate of the glitter powder.

[0079] After the glitter powder is discharged from the first feeding cylinder mechanism, the first closing plate 15 is rotated by the third motor 17, thereby closing the first feeding cylinder mechanism. The second closing plate 27 is rotated by the fourth motor 30, thereby closing the discharge assembly. When the limiting groove 4 corresponding to the first feeding cylinder mechanism moves to the bottom of the drying chamber 1 and is opposite to the clearance groove, the first motor 2 is paused, and the column 3 stops moving. The electromagnet 19 is de-energized. After losing the attraction of the electromagnet 19, under the action of the first spring 12, the two connecting blocks 8 move closer to each other, and the two arc-shaped perforated plates 9 move closer to each other, shortening the feeding cylinder mechanism 7. The limiting block 5 moves towards the limiting groove 4 and enters the limiting groove 4. The first feeding cylinder mechanism is then reconnected to the column 3.

[0080] The technique of stopping the first motor 2 when the limiting groove 4 corresponding to the first material-filling cylinder mechanism moves to the bottom of the drying chamber 1 and aligns with the clearance groove is a mature existing technology and will not be elaborated here. For example, a laser emitter can be installed on the connecting block 8, and a laser receiver can be installed in the limiting groove 4. When the first material-filling cylinder mechanism finishes discharging, the laser emitter is activated. When the limiting groove 4 corresponding to the first material-filling cylinder mechanism receives a laser signal, the first motor 2 stops, and the electromagnet 19 is de-energized. Since the laser receivers in other limiting grooves 4 are blocked by the limiting block 5, they will not receive a laser signal.

[0081] After the first material container mechanism is reconnected to the column 3, the electrically controlled telescopic push rod 34 is activated. The electrically controlled telescopic push rod 34 pushes the slider 31, causing the first loop plate 24 and the second loop plate 25 to move upward and reset. The second loop plate 25 pushes the first material container mechanism upward, the telescopic rod 6 shortens, and the first material container mechanism returns to its initial state.

[0082] Then, the first motor 2 drives the column 3 to continue rotating, and the column 3 drives the material container mechanism 7 to rotate, continuing to dry the glitter powder inside the material container mechanism 7. When the material container mechanism 7 passes the discharge assembly, the pressure sensor 26 detects the material container mechanism 7.

[0083] It should be noted that as the column 3 rotates, when the emptied material container mechanism 7 comes into contact with the discharge assembly, the material container mechanism 7 tends to move downwards under its own gravity, squeezing the pressure sensor 26 and causing the pressure sensor 26 to generate a pressure value. This pressure value of the pressure sensor 26 is set as the lower limit. When the detected value of the pressure sensor 26 is less than the preset value but greater than the lower limit, the first motor 2 stops, the electromagnet 19 is energized, and the electrically controlled telescopic top rod 34 shortens to discharge the dried material container mechanism 7.

[0084] The process continues until all the glitter powder in the multiple material container mechanisms 7 is dried and discharged through the discharge assembly.

[0085] Example 2: This example only describes the differences from Example 1. In this example, no weighing component is used. Instead, a humidity sensor is installed in each material container 7, and the humidity sensor is electrically connected to the controller. The humidity sensor detects the humidity value inside the drying chamber 1. The humidity sensor transmits the detected value to the controller. When the glitter powder in the material container 7 is dried, the humidity value inside the corresponding material container 7 is lower than a preset value, causing the dried material container 7 to move to the bottom of the drying chamber 1. This pauses the first motor 2, energizes the electromagnet 19, and shortens the electrically controlled telescopic top rod 34. This then discharges the dried material from the material container 7.

[0086] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
