[0002] Mica powder has a natural flaky structure and reflective properties. When added to toy materials (such as plastics and paints), it can produce a pearly luster or shimmering effect, making toys more attractive to children. It is commonly found on the surfaces of dolls, decorative stickers, or models.

[0003] Therefore, in order to improve the gloss effect of toys, packaged mica powder is usually sold with toy products. However, the packaging of mica powder requires precise quantity. The existing mica powder feeding and packaging process is mostly done manually, which cannot guarantee that each package is quantitative. Therefore, those skilled in the art have designed a quantitative feeding device for mica powder packaging. Summary of the Invention

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0023] Example

[0024] like Figure 1-4 As shown, a vibrating mica quantitative feeding device includes a control box 1 as a base, a quantitative feeding rack 2 fixedly installed above the control box 1, a mica powder hopper 3 fixedly installed above the quantitative feeding rack 2, a solenoid valve group 4 installed on the back of the control box 1, and a cup holder 5 placed between the control box 1 and the quantitative feeding rack 2 for holding mica powder.

[0025] An L-shaped corner plate 11 is welded on the top of the control box 1. An auxiliary baffle 12 is also welded on the same straight line as the L-shaped corner plate 11. Specifically, the L-shaped corner plate 11 and the auxiliary baffle 12 can be used to quickly and accurately place the cup holder 5, so that the cup in the cup holder 5 can be accurately loaded with mica powder.

[0026] The quantitative feeding rack 2 includes a quantitative feeding rack body 21 fixedly assembled with the control box 1, and an intercepting feeding component 22 installed at the center of the lower part of the quantitative feeding rack body 21.

[0027] The intercepting and feeding assembly 22 includes a mica powder metering plate 221 fixedly installed with the metering feeding frame 21, an upper intercepting plate 222 movably embedded above the mica powder metering plate 221, an upper intercepting plate driving cylinder 223 fixedly installed with the mica powder metering plate 221 and whose output end is fixedly connected to the upper intercepting plate 222, a lower intercepting plate 224 movably embedded below the mica powder metering plate 221, a lower intercepting plate driving cylinder 225 fixedly installed with the mica powder metering plate 221 and whose output end is fixedly connected to the lower intercepting plate 224, and a guide plate 226 located below the mica powder metering plate 221 and fixedly installed with the mica powder metering plate 221.

[0028] A hopper trough 211 is provided in the center of the quantitative feeding frame 21. Specifically, after the mica powder hopper 3 is fixedly installed with the quantitative feeding frame 21, the hopper trough 211 can correspond to the discharge part of the mica powder hopper 3 and align it with the intercepting feeding component 22.

[0029] The mica powder metering plate 221 has rectangular grooves 2211 on both the upper and lower surfaces for embedding the upper interceptor plate 222 and the lower interceptor plate 224, and six mica metering cavities 2212 are equally spaced at the locations where the rectangular grooves 2211 are opened.

[0030] The upper interceptor plate 222 has six upper interceptor plate through holes 2221 at fixed intervals. Specifically, the opening position of the upper interceptor plate through holes 2221 is aligned with the six mica metering cavities 2212 on the mica powder metering plate 221, and the radius of the upper interceptor plate through holes 2221 is smaller than the radius of the mica metering cavity 2212. When the upper interceptor plate driving cylinder 223 drives the upper interceptor plate 222 to move, the upper interceptor plate through holes 2221 move away from the mica metering cavity 2212 and cover the mica metering cavity 2212 through the upper interceptor plate 222. At this time, the mica powder in the mica powder hopper 3 is intercepted and no longer falls into the mica metering cavity 2212 through the upper interceptor plate through holes 2221.

[0031] The lower interceptor plate 224 has six through holes 2241 at fixed intervals. Specifically, the opening positions of the through holes 2241 are aligned with the six mica metering cavities 2212 on the mica powder metering plate 221, and the radius of the through holes 2241 is smaller than the radius of the mica metering cavities 2212. When the lower interceptor plate driving cylinder 225 drives the lower interceptor plate 224 to move, the through holes 2241 move away from the mica metering cavities 2212, and the lower interceptor plate 224 abuts against the mica. The bottom of the mica metering cavity 2212 is closed at this time, which facilitates the equal loading of mica powder in the mica metering cavity 2212. When the lower interceptor plate driving cylinder 225 drives the lower interceptor plate 224 to move so that the lower interceptor plate through hole 2241 moves to align with the mica metering cavity 2212, the mica powder quantitatively filled by the mica metering cavity 2212 falls into the guide plate 226 through the lower interceptor plate through hole 2241, and then falls into the holding cup in the cup holder 5 through the guide plate 226.

[0032] The guide plate 226 has six integrally formed discharge cones 2261. Specifically, the mica powder can be accurately introduced into the holding cup in the cup holder 5 through the discharge cones 2261.

[0033] The mica powder hopper 3 includes a hopper body 31, six discharge holes 32 opened at the lower end of the discharge section of the hopper body 31, and an air valve vibrator 33 installed on the outer side of the hopper body 31. Specifically, the air valve vibrator 33 vibrates to control the mica powder inside the hopper body 31 so that it can fall evenly through the discharge holes 32 into the mica powder metering plate 221 for metered filling.

[0034] The cup holder 5 includes a cup holder plate 51, four anti-slip feet 52 welded to the bottom corners of the cup holder plate 51, six cup holder openings 53 equidistantly opened on the cup holder plate 51 for fixing cups, and an annular groove 54 opened around the cup holder openings 53 for collecting scattered mica powder.

[0035] It should be further explained that the solenoid valve group 4 is connected to the upper interceptor plate drive cylinder 223, the lower interceptor plate drive cylinder 225 and the valve vibrator 33 respectively. It can be manually operated by the control box 1 so that the upper interceptor plate drive cylinder 223, the lower interceptor plate drive cylinder 225 and the valve vibrator 33 can be operated at timed intervals under manual control, so as to achieve efficient and high-precision quantitative dispensing of mica powder.

[0036] In summary, the feeding steps of the vibratory mica quantitative feeding device can be summarized as follows, the core of which is to achieve precise dispensing through the alternating action of the intercepting plates:

[0037] S1. Initial Preparation Phase:

[0038] The cup holder 5 is positioned by the L-shaped corner plate 11 and the auxiliary baffle 12, and the cup is aligned with the discharge cone 2261 of the guide plate 226;

[0039] The air valve vibrator 33 is activated, making the powder in the mica powder hopper 3 loose and uniform;

[0040] The upper interceptor plate drive cylinder 223 retracts, the upper interceptor plate 222 through hole moves away from the mica metering cavity 2212, and closes the feed inlet; the lower interceptor plate drive cylinder 225 retracts, the lower interceptor plate 224 through hole moves away from the metering cavity, and closes the discharge outlet;

[0041] S2. Quantitative cavity filling stage:

[0042] The upper interceptor plate drive cylinder 223 extends and pushes the upper interceptor plate 222 to move, so that the through hole 2221 of the upper interceptor plate is aligned with the top of the mica metering chamber 2212, and the mica powder in the hopper 3 falls into the metering chamber through the discharge hole 32.

[0043] The air valve vibrator 33 vibrates continuously to ensure that the powder fills the metering cavity evenly and avoids voids or uneven accumulation.

[0044] After filling is completed, the upper interceptor plate drive cylinder 223 retracts, and the upper interceptor plate 222 resets to seal the top of the metering chamber, stopping the feeding.

[0045] S3. Quantitative powder release stage:

[0046] The lower interceptor plate drive cylinder 225 extends, pushing the lower interceptor plate 224 to move, so that the lower interceptor plate through hole 2241 is aligned with the bottom of the mica metering cavity 2212, and the metered mica powder falls through the through hole;

[0047] The discharge cone 2261 of the guide plate 226 guides the powder to fall precisely into the holding cup of the cup holder 5;

[0048] After the release is complete, the lower interceptor plate drives the cylinder 225 to retract, resetting and sealing the bottom of the metering chamber, preparing for the next cycle;

[0049] S4. Loop Control:

[0050] The solenoid valve group 4 controls the cylinder to operate according to the set timing sequence, realizing the alternating opening and closing of the upper and lower interceptor plates to form continuous quantitative feeding;

[0051] The vibrator is started and stopped intermittently during the filling stage to balance the powder flow efficiency and dust control requirements.

[0052] Key collaborative logic: The upper and lower interceptor plates strictly follow the interlocking logic of "upper opening and lower closing during filling, upper closing and lower opening during release" to avoid powder leakage or double blockage.

[0053] The vibration intensity is matched with the cylinder's operating speed to ensure uniform filling while preventing overflow from the metering chamber.

All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
