[0022] In the above scheme, when the pearl powder in the rotating drum 2 needs to be poured, the handle 201 is moved to the left to be out of the limit of the limiting frame 202, at which time the handle 201 can drive the rotating drum 2 to rotate, so as to pour the pearl powder in the rotating drum 2.

[0023] As shown in Figures 5-10 , the extrusion assembly comprises an electric push rod 10 arranged on the upper side of the rotating frame 6, the telescopic part of the electric push rod 10 is provided with a rotating platform 11, the lower part of the rotating platform 11 is provided with an extrusion plate 12, the lower side of the extrusion plate 12 is provided with a plurality of grooves, the extrusion plate 12 is slidingly connected with a fixed shell 13, there is a gap between the fixed shell 13 and the guide shell 7, the extrusion plate 12 is provided with a second spring in contact with the fixed shell 13, the lower side of the fixed shell 13 is fixedly connected with a rotating frame 14, the rotating frame 14 is composed of a plurality of arc-shaped plates and a circular ring fixedly connected with each other, and the plurality of grooves in the extrusion plate 12 correspond one-to-one with the plurality of arc-shaped plates in the rotating frame 14.

[0024] In the above scheme, the rotating platform 11 is composed of a rotating part and a fixed part, the rotating part is fixedly connected with the telescopic part of the electric push rod 10, when the rotating frame 14 moves downward to the outer edge in contact with the outer edge of the bottom shell 8, the arc-shaped plates in the rotating frame 14 have been attached to the adjacent fixed plates 9, at which time the rotating frame 14 rotates 90°, so that all the fixed plates 9 and all the arc-shaped plates in the rotating frame 14 are in a grid shape from top to bottom, in this process, the pearls fall into the grid and are arranged, so that the pearls remain stable when being extruded subsequently, then through the downward movement of the extrusion plate 12, the grooves in the extrusion plate 12 contact the arc-shaped plates in the rotating frame 14, so that the continuous downward movement of the extrusion plate 12 extrudes and breaks the pearls in the grid, thus realizing the effect of first placing the pearls in the grid for limitation and then breaking.

[0025] As shown in Figure 5 and Figure 10 , the extrusion plate 12 is provided with a driving module 1201 for driving it to rotate along the rotating platform 11.

[0026] In the above scheme, the driving module 1201 is composed of a second driving motor and a gear set, the second driving motor is installed on the extrusion plate 12, and the gear set is installed on the rotating part of the rotating platform 11 and the driving shaft of the second driving motor respectively.

[0027] As shown in Figure 3 , the upper side of the fixed shell 13 is fixedly connected with a guide plate 1301, and the fixed part of the electric push rod 10 passes through the guide plate 1301.

[0028] In the above scheme, the guide plate 1301 is used to guide the pearls into the gap between the fixed shell 13 and the guide shell 7, and the upper side of the guide plate 1301 is provided with an annular inclined surface.

[0029] Working principle: when the need to grind the pearls, the user first remove the cover plate 4, then put into the barrel 2 pearls, pearls in the process of falling through the gap between the guide shell 7 and fixed shell 13 (pearls in the process of falling will also be guided by the guide plate 1301 and enter the gap between the guide shell 7 and fixed shell 13), eventually fall into the upper side of the bottom shell 8.

[0030] When the required pearl falls to the upper side of the bottom shell 8, the pearls are separated by several fixed plates 9, arranged on the upper side of the bottom shell 8, and under the action of the downward concave on the upper side of the bottom shell 8, the pearls are dispersed on the upper side of the bottom shell 8, then the user controls the extension of the electric push rod 10 to move downward by the control terminal, the extension of the electric push rod 10 immediately drives the extrusion plate 12 to move downward through the rotating platform 11, and the extrusion plate 12 is indirectly extruded by the second spring.

[0031] When the rotating frame 14 moves downward to the outer edge in contact with the outer edge of the bottom shell 8, the arc plate in the rotating frame 14 has been attached to the adjacent fixed plate 9, at which time the drive module 1201 drives the extrusion plate 12, the extrusion plate 12 drives the rotating frame 14 and its attached parts to rotate 90° along the rotating platform 11 through the fixed shell 13, so that all the fixed plates 9 and all the arc plates in the rotating frame 14 are grid-shaped from top to bottom, and the pearls are arranged through the grid to keep stable when being extruded subsequently, at this time the user controls the extension of the electric push rod 10 to continue moving downward by the control terminal, the extension of the electric push rod 10 drives the extrusion plate 12 to continue moving downward through the rotating platform 11, at this time the rotating frame 14 has moved to the limit position, therefore, the extrusion plate 12 slides downward along the fixed shell 13 (the second spring is extruded in the process of relative movement between the two), the groove in the extrusion plate 12 contacts the arc plate in the rotating frame 14 in the process of moving downward, and the pearls in the grid are extruded and broken through the continuous downward movement of the extrusion plate 12, thus realizing the effect of first limiting the pearls in the grid and then breaking them.

[0032] When the pre-treatment of the pearls is completed, the extension of the electric push rod 10 is controlled to move upward by the control terminal, the extension of the electric push rod 10 drives the extrusion plate 12 to move upward and reset through the rotating platform 11, at this time the extrusion plate 12 first moves away from the fixed shell 13 (achieved by the release of the elastic force of the second spring), then the extension of the electric push rod 10 continues to move upward until it moves to Figure 5 the state, at which time the electric push rod 10 stops, the pre-treatment of the pearls is completed, then the extrusion plate 12 is driven by the drive module 1201, the extrusion plate 12 drives the rotating frame 14 and its attached parts to rotate 90° in the opposite direction along the rotating platform 11 through the fixed shell 13.

[0033] After the pre-treatment of the pearls is completed, the user rotates the rotating frame 6, which drives the parts thereon to rotate, so that the pre-treated pearls in the bottom shell 8 fall to the bottom of the rotating drum 2. Then, the rotating frame 6 is rotated in the opposite direction, so that the rotating frame 6 is in the state shown in the drawing. At this time, the next batch of pearls to be treated can be put into the rotating drum 2, and the above-mentioned pre-treatment of the pearls can be repeated.

[0034] When the pre-treatment of the pearls is completed, the grinding module 5 is controlled by the control terminal to grind the pearls in the rotating drum 2. When the grinding of the pearls is completed, the finished pearl powder is obtained. Then, the user dismounts the cover plate 4, the rotating frame 6 and the associated parts, and then pushes the handle 201 to the left, so that the handle 201 is extruded from the limiting of the limiting frame 202 in the process of extruding the first spring. Finally, the user holds the handle 201 and rotates it, so that the handle 201 drives the rotating drum 2 to rotate along the moving frame 1. When the rotating angle of the rotating drum 2 is sufficient to make the pearl powder in it discharge, the pearl powder is discharged from the rotating drum 2.

[0035] After the pearl powder is discharged from the rotating drum 2, the user rotates the handle 201 in the opposite direction, so that the handle 201 drives the rotating drum 2 to rotate in the opposite direction, and the rotating drum 2 returns to the state shown in the drawing. Then, the user releases the handle 201, and the handle 201 is close to the limiting frame 202 under the action of the first spring, so as to restore the limiting of the handle 201.

[0036] Example 2 On the basis of Embodiment 1, in order to enhance the pre-treatment efficiency of the pearls, this embodiment makes the pearls move in the process of being extruded by knocking, so as to avoid the generation of local accumulation problem; As Figures 10-14As shown, the telescopic part of the electric push rod 10 is provided with an elastic telescopic rod 21, the telescopic part of the elastic telescopic rod 21 is provided with a pressing ball 22 for knocking the rotating platform 11, the fixed part of the electric push rod 10 is fixedly connected with a guide frame 15, the guide frame 15 penetrates through a guide plate 1301, the guide frame 15 is provided with a first guide slot 16 arranged in a ring array, the lower side of the guide frame 15 is slidably connected with a sliding shell 17, the sliding shell 17 is provided with a second guide slot 18 arranged in a ring array, the second guide slot 18 is communicated with the adjacent first guide slot 16, the telescopic part of the electric push rod 10 is provided with a sliding frame 19, the sliding frame 19 slides along the first guide slot 16 arranged in a ring array and the second guide slot 18 arranged in a ring array, the telescopic part of the electric push rod 10 is fixedly connected with a fixed ring 1901, the fixed ring 1901 and the sliding frame 19 are fixedly connected with a tension spring 1902 located in the guide frame 15 and the sliding shell 17, the outer side of the sliding frame 19 is fixedly connected with a connecting frame 20, the connecting frame 20 is fixedly connected with the elastic telescopic rod 21, the first guide slot 16 is composed of inclined slots and vertical slots communicated with each other, the widths of the two sides of the inclined slot are inconsistent, the guide frame 15 is fixedly connected with a spring limiting pin 23 arranged in a ring array, the spring limiting pin 23 is located at the position where the inclined slot and the vertical slot are communicated in the adjacent first guide slot 16, and the spring limiting pin 23 arranged in a ring array is used for temporarily blocking the sliding of the sliding frame 19.

[0037] In the above scheme, the outer side of the pressing plate 12 and the fixed shell 13 can be fixedly connected with a flexible ring, which is used for reducing the influence of vibration on the parts in the guide shell 7, the sliding frame 19 is composed of a circular ring and two fixed columns fixedly connected with each other, the first guide slot 16, the second guide slot 18, the elastic telescopic rod 21 and the pressing ball 22 are two in the present application, the telescopic part of the electric push rod 10 is pulled during the extension, under the action of the sliding frame 19 temporarily blocked by the spring limiting pin 23, the tension spring 1902 is preferentially stretched, when the pulling force of the tension spring 1902 pulling the sliding frame 19 is greater than the force provided by the spring limiting pin 23 limiting the sliding frame 19, the sliding frame 19 is forced to extrude and shrink the spring limiting pin 23 into the guide frame 15, at this time, the tension spring 1902 is released, the pressing ball 22 knocks the rotating platform 11, under the action of the parts transmitting vibration force, the pressing plate 12 vibrates in the process of pressing the pearls, so as to avoid local accumulation, the distance between the upper side of the spring limiting pin 23 and the lower side of the inclined slot in the first guide slot 16 is greater than the diameter of the fixed column on the outer side of the sliding frame 19, the width of the inclined slot in the second guide slot 18 gradually increases from top to bottom, which is used for preventing the sliding frame 19 from being blocked by the spring limiting pin 23 when it is reset.

[0038] Working principle: when the pearl on the upper side of the bottom shell 8 needs to be extruded, the control terminal controls the extension of the electric push rod 10 to move downward, the extension of the electric push rod 10 drives the fixed ring 1901 and the sliding shell 17 to move synchronously, the sliding shell 17 slides downward along the guide frame 15, and the fixed ring 1901 pulls the sliding frame 19 to slide downward along the two first guide grooves 16 through the tension spring 1902.

[0039] When the sliding frame 19 is blocked by the two spring limiting pins 23, and the pulling force of the tension spring 1902 is less than the supporting force of the two spring limiting pins 23 on the sliding frame 19, the fixed ring 1901 continues to move, the tension spring 1902 is stretched, and the sliding frame 19 is blocked.

[0040] When the extrusion plate 12 extrudes the pearl, the pulling force of the tension spring 1902 is greater than the supporting force of the two spring limiting pins 23 on the sliding frame 19, at which time the tension spring 1902 pulls the sliding frame 19 downward, and the sliding frame 19 moves downward and extrudes the two spring limiting pins 23, so that the two spring limiting pins 23 are retracted. During the downward movement of the sliding frame 19, the two elastic extension rods 21 and the two extrusion balls 22 are driven to move downward synchronously through the connecting frame 20 (the sliding frame 19 will rotate compared with the guide frame 15 during the downward movement of the sliding frame 19), and the pulling force generated by the tension spring 1902 causes the extrusion balls 22 to knock the rotating platform 11, and the vibration force is transmitted to the extruded pearl through the extrusion plate 12 and the rotating platform 11, so that the local accumulation of the pearl can be dispersed by the vibration force generated by the knocking during the extrusion process.

[0041] When the knocking of the pearl is completed, the sliding frame 19 has slid into the second guide groove 18 from the first guide groove 16, and then the control terminal controls the extension of the electric push rod 10 to drive the fixed ring 1901 and the sliding shell 17 to move upward synchronously, the sliding shell 17 slides upward, the sliding frame 19 gradually slides into the first guide groove 16 from the second guide groove 18, and the sliding shell 17 moves from the vertical groove in the second guide groove 18 to the inclined groove. During the movement of the sliding shell 17, the sliding frame 19 passes through the spring limiting pin 23 and slides from the lower side to the upper side of the inclined groove in the second guide groove 18 (for reference, see the accompanying drawings), and the resetting of the sliding frame 19 is completed. When the pearl needs to be processed again, the above steps can be repeated.

[0042] Example 3 On the basis of embodiment 2, a grinding method for producing water-soluble pearl powder is shown in Figures 1-14 Based on a grinding device for producing water-soluble pearl powder, the specific steps are as follows: S1: When the pearl needs to be pretreated, the pearl falls onto the upper side of the bottom shell 8, and the pearl is arranged on the upper side of the bottom shell 8 by the spacing of the plurality of fixed plates 9; S2: After the pearls are arranged, the telescopic part of the electric push rod 10 extends out, causing the rotating platform 11 to drive the pressing plate 12 and indirectly press the fixed shell 13 through the second spring, causing the fixed shell 13 to drive the rotating frame 14 to move. At the same time, the fixed ring 1901 and the sliding shell 17 move synchronously. The fixed ring 1901 pulls the sliding frame 19 along the two first guide grooves 16 through the tension spring 1902. S3: When the sliding frame 19 is blocked by the spring limiting pin 23, the tension spring 1902 is stretched and the sliding frame 19 is blocked. At this time, the tension of the tension spring 1902 is less than the supporting force of the two spring limiting pins 23 on the sliding frame 19. S4: When the arc-shaped plate inside the rotating frame 14 is in contact with the adjacent fixed plate 9, the rotating frame 14 rotates 90° along the rotating platform 11 so that all the fixed plates 9 and all the arc-shaped plates inside the rotating frame 14 appear as a grid when viewed from top to bottom; S5: After all the fixed plates 9 and all the arc plates in the rotating frame 14 form a grid, the telescopic part of the electric push rod 10 continues to drive the extrusion plate 12 to move. When the tension of the tension spring 1902 is greater than the supporting force of the two spring limit pins 23 on the sliding frame 19, the tension spring 1902 pulls the sliding frame 19. The sliding frame 19 drives the elastic telescopic rod 21 and the extrusion ball 22 to move, so that the extrusion ball 22 strikes the rotating platform 11. The vibration force is transmitted to the extrusion plate 12 through the rotating platform 11 to the extruded pearl, so that the pearl vibrates during the extrusion process. S6: After the pretreatment of the pearl is completed, the telescopic part of the electric push rod 10 drives the pressing plate 12 to reset. S7: After the pretreatment of the pearl is completed, the rotating frame 6 drives the bottom shell 8 to rotate, causing the pretreated pearl inside the bottom shell 8 to fall to the bottom of the rotating cylinder 2, and then the grinding module 5 grinds the pearl.

10. A grinding method for producing water-soluble pearl powder, comprising the grinding equipment for producing water-soluble pearl powder according to claim 9, characterized in that, The specific steps are as follows: S1: When pearls need to be pre-treated, the pearls fall into the upper side of the bottom shell (8) and are separated by several fixing plates (9) so that the pearls are arranged on the upper side of the bottom shell (8). S2: After the pearls are arranged, the telescopic part of the electric push rod (10) extends out, causing the rotating platform (11) to drive the pressing plate (12) and indirectly press the fixed shell (13) through the second spring, causing the fixed shell (13) to drive the rotating frame (14) to move. At the same time, the fixed ring (1901) and the sliding shell (17) move synchronously. The fixed ring (1901) pulls the sliding frame (19) along the two first guide grooves (16) through the tension spring (1902). S3: When the sliding frame (19) is blocked by the spring limiting pin (23), the tension spring (1902) is stretched and the sliding frame (19) is blocked. At this time, the tension of the tension spring (1902) is less than the supporting force of the two spring limiting pins (23) on the sliding frame (19). S4: When the arc plate inside the rotating frame (14) is in contact with the adjacent fixed plate (9), the rotating frame (14) rotates 90° along the rotating platform (11) so that all the fixed plates (9) and all the arc plates inside the rotating frame (14) appear as a grid when viewed from top to bottom; S5: After all the fixed plates (9) and the arc plates in the rotating frame (14) form a grid, the telescopic part of the electric push rod (10) continues to drive the extrusion plate (12) to move. When the tension of the tension spring (1902) is greater than the support force of the two spring limit pins (23) on the sliding frame (19), the tension spring (1902) pulls the sliding frame (19), and the sliding frame (19) drives the elastic telescopic rod (21) and the extrusion ball (22) to move, so that the extrusion ball (22) strikes the rotating platform (11), and the vibration force is transmitted to the extrusion plate (12) through the rotating platform (11) to the extrusion pearl, so that the pearl vibrates during the extrusion process. S6: After the pretreatment of the pearl is completed, the telescopic part of the electric push rod (10) drives the extrusion plate (12) to reset. S7: After the pretreatment of the pearl is completed, the rotating frame (6) drives the bottom shell (8) to rotate, so that the pretreated pearl inside the bottom shell (8) falls to the bottom of the rotating cylinder (2), and then the grinding module (5) grinds the pearl.
