Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a fine crushing device for microcapsule powder essence. Background Art

[0002] As a new type of flavor product, microcapsule powder flavor is widely welcomed in the market because it can control the release rate of flavor, prolong the fragrance time, and protect the flavor from the external environment. Before making microcapsules, the flavor needs to be crushed to improve the quality of microcapsule powder flavor.

These devices usually use a fixed grinding mechanism, and its grinding force and grinding effect are difficult to adjust, so they cannot adapt to flavor products with different particle size requirements. Secondly, the microcapsule powder of the existing grinding device cannot be screened during the grinding process, resulting in uneven coarseness and fineness, which affects the product quality.

[0022] See also Figure 1-5 , the utility model provides a technical solution:

[0023] A fine grinding device for microcapsule powder flavor comprises a grinding bin 1, a feeding port 11 is provided on the top of the grinding bin 1, two grinding rollers 4 are arranged in the inner cavity of the grinding bin 1, the two grinding rollers 4 are powered by a driving motor 12 to generate high-speed rotation, the grinding rollers 4 comprise a power shaft 41, a grinding plate 42 is arranged on both sides of the power shaft 41, the two grinding plates 42 are connected by a connecting plate 43, and the grinding plates 42 can move along the outer side of the connecting plate 43, and an adjusting plate 42 is arranged inside the power shaft 41. The regulating mechanism 44 includes a servo motor 441, the output end of the servo motor 441 is fixedly connected to a driving shaft 442, one end of the driving shaft 442 is provided with a driving gear 443, and the first linking bar 444 and the second linking bar 445 are respectively provided on both sides of the driving gear 443, and one end of the first linking bar 444 and the second linking bar 445 are provided with a push-pull plate 446, one side of the push-pull plate 446 is connected to the inner wall of the crushing plate 42, and a screening bin 2 is provided at the bottom of the crushing bin 1.

[0024] In this embodiment, please refer to Figure 5The screening bin 2 includes a bin body 21, a discharge port 22 is provided at the bottom of the bin body 21, a sieve plate 23 is provided in the inner cavity of the bin body 21, and a vibration motor 24 is provided at the inner wall of the bin body 21 at the bottom of the sieve plate 23. The sieve plate 23 can generate high-frequency vibration through the vibration motor 24, and a pouring port 25 is provided on one side of the bin body 21. A rework bin 26 is provided on one side of the pouring port 25, and one side of the sieve plate 23 is arranged to be inclined toward the pouring port 25. In this embodiment, the sieve plate 23 is powered by the vibration motor 24 to generate high-frequency vibration, which can separate the flavor particles with larger particle size, and make the flavor particles with large particle size slide through the inclined surface of the sieve plate 23 into the inner cavity of the rework bin 26, and the flavor particles discharged through the discharge port 22 meet the standards, and the large particle size particles that do not meet the standards are removed.

[0025] In this embodiment, please refer to Figure 4 The corresponding surfaces of the second linkage bar 445 and the first linkage bar 444 are both provided with gear grooves, and the gear grooves are adapted to the outer edge of the driving gear 443. When the driving gear 443 rotates, the second linkage bar 445 and the first linkage bar 444 can move. In this embodiment, since the first linkage bar 444 and the second linkage bar 445 are arranged on both sides of the driving gear 443, when the driving gear 443 rotates, the first linkage bar 444 and the second linkage bar 445 can be driven to move toward or away from each other.

[0026] In this embodiment, please refer to Figure 5 The number of sieve plates 23 is at least two, and they are arranged in the inner cavity of the bin body 21 from top to bottom, and a return bin is provided on the inclined side of each sieve plate 23, and a vibration motor 24 is provided at the bottom of each sieve plate 23. The filter holes of the sieve plate 23 gradually become smaller from top to bottom. In this embodiment, by providing multiple sieve plates 23, multiple screening of the flavor powder can be performed to meet different production needs, and at the same time, more delicate flavor powder can be obtained.

[0027] In this embodiment, please refer to Figure 1 , Figure 5 A pneumatic conveyor 3 for conveying flavor powder is provided on one side of the crushing bin 1, a suction pipe 32 is provided at the suction end of the pneumatic conveyor 3, and a feeding pipe 31 is provided at the discharge end of the pneumatic conveyor 3. One end of the suction pipe 32 passes through the rework bin 26 and is interconnected with the inner cavity of each rework bin 26. In this embodiment, when the sieved flavor powder enters the rework bin 26, if these powders do not meet the production requirements, they are conveyed to the inner cavity of the crushing bin 1 through the feeding pipe 31 and reprocessed.

[0028] In this embodiment, please refer to Figure 1A return port 13 is provided on the top of the inner wall of the crushing bin 1 above the crushing roller 4, and one end of the feed pipe 31 is connected with the inner cavity of the crushing bin 1 through the return port 13. In this embodiment, it is ensured that the reworked large-particle flavor powder can be crushed again by the crushing roller 4. At the same time, the pneumatic conveyor 3 is through an air compressor or a centrifugal fan, and pushes the flavor powder to move in the pipeline.

[0029] Working principle of this utility model:

[0030] Step 1: Power is given by the servo motor 441 to control the driving shaft 442 to drive the driving gear 443 to rotate. Since the outer edge of the driving gear 443 is meshed with the inner sides of the first linkage bar 444 and the second linkage bar 445, when the driving gear 443 rotates, the first linkage bar 444 and the second linkage bar 445 can be driven to move, and the first linkage bar 444 and the second linkage bar 445 can be controlled to move toward or away from each other by controlling the rotation direction of the driving gear 443. When the first linkage bar 444 and the second linkage bar 445 are in rotation, the first linkage bar 444 and the second linkage bar 445 are in rotation. When the back-and-forth movement occurs, the two push-pull plates 446 are driven to gradually increase the distance between them, thereby pushing the rolling plate 42 to move outward, increasing the overall diameter of the grinding roller 4, so that the gap between the two grinding rollers 4 becomes smaller, and the particle size of the flavor powder produced by the grinding rollers 4 becomes smaller. When the first linkage bar 444 and the second linkage bar 445 produce opposite movements, the push-pull plate 446 drives the two grinding plates 42 to move closer to the power shaft 41, so that the distance between the two grinding rollers 4 becomes larger, and the particle size of the flavor powder produced by the grinding rollers 4 becomes larger.

[0031] Step 2: The essence is crushed into powder after passing through the crushing bin 1 and falls into the inner cavity of the screening bin 2. Since a sieve plate 23 is provided in the screening bin 2, the essence powder falls on the upper surface of the sieve plate 23. The vibration motor 24 provides power to vibrate the sieve plate 23, and the essence powder with a particle size smaller than the filter holes on the sieve plate 23 falls into the sieve plate of the next layer. As the sieve plate 23 is inclined toward the reworking bin 26, the essence powder with a larger particle size slides into the inner cavity of the reworking bin 26 through the pouring port 25 under the continuous vibration of the sieve plate 23. The pneumatic conveyor 3 can be started according to production needs. The air compressor and centrifugal fan of the pneumatic conveyor 3 will transfer the essence powder to the inner cavity of the crushing bin 1 through the suction pipe 32 and the feeding pipe 31, and re-crush it through the crushing rollers 4. The essence powder can also be re-processed to a suitable particle size by adjusting the spacing between the crushing rollers 4.

The above embodiments and descriptions are only for explaining the principle of the utility model. The utility model may have various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
