Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0052] In the utility model, unless otherwise specifically defined and limited, the terms "connection", "fixing" and the like should be understood broadly, for example, "fixing" can be fixed connection, or detachable connection, or integral; "connection" can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically limited. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0053] Referring to Figure 1 and Figure 2 The utility model provides a carousel formula multi -element accurate blending equipment, carousel formula multi -element accurate blending equipment includes roof 1, carousel 2, collector 3, stirring bucket 4, a plurality of tension load cell 5 and a plurality of bunker 6, the lower part of roof 1 is surrounded with a plurality of tension load cell 5, the free end of a plurality of tension load cell 5 is connected with the top end of a plurality of bunker 6 one by one, the discharge port of bunker 6 is provided with electromagnetic valve 61 to open and close the discharge port of bunker 6, the lower part of bunker 6 is provided with carousel 2, the carousel 2 is provided with the discharge port 21, collector 3 is connected with the discharge port 21, stirring bucket 4 is set up in the lower part of discharge port 21, wherein carousel 2 can drive the material collecting port of collector 3 to rotate to the lower part of the discharge port of bunker 6, and the material collecting port of collector 3 can rotate to the feed inlet of stirring bucket 4.

[0054] Collector 3 is the collection container of mixed powder, and the mixed powder can be unloaded into stirring bucket 4 by turning over 180°. Collector 3 can be hemispherical, square or conical, etc. The shape of the discharge port 21 is matched with the shape of the collector 3 to ensure that the collector 3 can be normally turned over 180°. It should be noted that if the weight of the bunker 6 is heavy, a plurality of auxiliary springs can be added to the top end of the bunker 6, and the auxiliary spring is provided with a telescopic rod to improve the connection strength between the roof 1 and the bunker 6. Of course, after adding the auxiliary spring, the measurement of the tension load cell 5 needs to be converted accordingly.

[0055] The weight of the bunker 6 and the powder inside the bunker 6 is measured directly by the tension load cell 5, and the weight of the powder inside the bunker 6 can also be measured directly. The tension load cell 5 can be arranged on the vertical extension line of the center of gravity of the bunker 6 to accurately measure the weight of the powder inside the bunker 6. The reduction of the powder is the proportioning amount put into the collector 3. Compared with the indirect measurement method of the pressure sensor at the bottom of the conveyor belt, the tension load cell 5 directly measures by hanging, which effectively reduces the measurement error and improves the mixing liquid proportioning accuracy.

[0056] The carousel 2 is arranged below the plurality of circumferentially arranged bunkers 6, Figure 2The dashed line in the figure is the moving curve of the feeding opening 21 during rotation, and the collector 3 and the feeding opening 21 are arranged below the discharge opening of the hopper 6. When the rotary disc 2 rotates, the collector 3 and the feeding opening 21 can rotate synchronously, thereby corresponding to realize the discharge of multiple hoppers 6. After the collector 3 completes the collection of the required powder, it can be flipped by 180° to pour the mixed powder in the interior through the feeding opening 21 into the stirring barrel 4. Compared with the linear feeding mode of the conveying belt, the one-way space occupation of the rotary disc feeding mode is smaller, thereby improving the installation adaptability of the rotary disc multi-element precise blending device. Moreover, the smaller the diameter of the circle surrounded by the multiple hoppers 6 arranged around, the smaller the space occupation of the rotary disc multi-element precise blending device. The actual number and weight requirements of the hoppers 6 can be set.

[0057] In the first embodiment, as shown in Figure 3 and Figure 4 The collector 3 includes a hemispherical shell 31, a hinged rod 32, a connecting rod 33 and a motor 34. The hemispherical shell 31 is arranged at the top end of the feeding opening 21. The two sides of the hemispherical shell 31 are connected with the hinged rod 32 and the connecting rod 33. The hinged rod 32 is rotationally connected with the rotary disc 2. The connecting rod 33 is rotationally connected with the motor 34. The motor 34 can drive the hemispherical shell 31 to rotate around the axis of the connecting rod 33. Specifically, the rotation and support of the hemispherical shell 31 at the feeding opening 21 are realized by the hinged rod 32 and the connecting rod 33. The rotation of the hemispherical shell 31 is driven by the motor 34, thereby realizing the flipping and discharging action of the hemispherical shell 31, which is simple and practical to operate. The inner wall of the hemispherical shell 31 is arc-shaped, which facilitates the collection of the powder after falling through the arc-shaped surface to the center position at the bottom end of the hemispherical shell 31, thereby effectively avoiding the accumulation of the powder on the two sides of the inner wall of the hemispherical shell 31 to affect the subsequent feeding of the powder and avoiding the dust of the powder to affect the blending accuracy.

[0058] Further, an arc-shaped groove 22 is formed at the top end of the rotary disc 2. The connecting rod 33 is coaxially and rotationally connected with the arc-shaped groove 22. In the first embodiment, the components of the collector 3 are arranged at the top end of the rotary disc 2, thereby facilitating the disassembly and maintenance of the components of the collector 3. The arc-shaped groove 22 can be internally provided with a bearing, which is sleeved on the connecting rod 33, thereby further enhancing the bearing capacity of the hemispherical shell 31 through the arc-shaped groove 22.

[0059] Secondly, the collector 3 further comprises a first bevel gear 35, a second bevel gear 36 and a first transmission shaft 37; the first bevel gear 35 is connected with the connecting rod 33; the second bevel gear 36 is sleeved on the first transmission shaft 37 and is in meshing transmission with the first bevel gear 35; the first transmission shaft 37 is connected with the motor 34; the inside of the rotating disc 2 is provided with a cavity 23; the second bevel gear 36 is arranged in the cavity 23; the first transmission shaft 37 is rotationally connected with the cavity 23 after penetrating through the second bevel gear 36. Specifically, the first transmission shaft 37 is fixedly installed in the cavity 23, which further improves the load-bearing capacity of the hemispherical shell 31 and the transmission stability of the collector 3.

[0060] In addition, the feeding port 21 comprises a clearance section 211 and an expanding section 212 which are in communication; the upper part of the hemispherical shell 31 is arranged in the clearance section 211, and the lower part of the hemispherical shell 31 is arranged in the expanding section 212; the diameter of the port of the expanding section 212 facing the clearance section 211 is smaller than the diameter of the port away from the clearance section 211. Specifically, when the mixed powder in the hemispherical shell 31 is poured, part of the mixed powder will first fall on the clearance section 211 and slide along the wall surface of the clearance section 211 synchronously with the rotation of the hemispherical shell 31 until the collecting port of the hemispherical shell 31 is opened to the expanding section 212, and then the mixed powder is hung and falls into the stirring barrel 4 through the expanding section 212. Since the diameter of the top port of the expanding section 212 is smaller than the diameter of the bottom port, the mixed powder can be effectively prevented from adhering to the wall surface of the expanding section 212, and the mixing precision of the mixed liquid is further improved.

[0061] To avoid the mixed powder adhering to the clearance section 211, the setting height of the clearance section 211 can be reduced, or the hemispherical shell 31 can be rotationally connected with the clearance section 211, and the powder adhering to the clearance section 211 is scraped off by the wall surface of the collecting port of the hemispherical shell 31, so as to ensure the feeding precision of the mixed powder.

[0062] Further, the bottom end of the hemispherical shell 31 is provided with a vibrator 7. The vibrator 7 is an eccentric vibrator. When the collecting port of the hemispherical shell 31 faces the feeding port of the stirring barrel 4, the vibrator 7 is started, and the vibration generated by the vibrator 7 shakes the powder adhering in the hemispherical shell 31 out, further improving the feeding precision of the mixed powder.

[0063] In the second embodiment, referring to Figure 5In the embodiment, the semi-spherical shell 31, the articulated rod 32 and the connecting rod 33 are arranged inside the rotary disc 2, and the motor 34 is arranged on the side of the rotary disc 2, so that the material collector 3 does not interfere with the top surface space of the rotary disc 2, thereby reducing the distance between the hopper 62 and the top surface of the rotary disc 2, effectively preventing powder dust, and improving the powder proportioning accuracy. Optionally, an extended section 311 is additionally arranged at the top end of the semi-spherical shell 31, that is, the semi-spherical shell 31 is between semi-spherical and spherical, which can effectively prevent powder dust on the one hand, and make the top surface of the semi-spherical shell 31 and the top surface of the rotary disc 2 be at the same level on the other hand, thereby sealing the gap between the two, effectively preventing external dust or impurities from entering the gap, so as to ensure the feeding accuracy of the material collector 3.

[0064] As shown in the drawings, Figure 6 The bin 6 further includes a hopper 62, a large-diameter discharge port, a vertical pipe 63 and a compensation discharge port; the tension weigher 5 is connected with the hopper 62; the compensation discharge port is communicated with the hopper 62 through the vertical pipe 63; the large-diameter discharge port and the compensation discharge port are both provided with electromagnetic valves 61; and the diameter of the large-diameter discharge port is larger than that of the compensation discharge port. Specifically, the large-diameter discharge port has a large diameter and discharges fast, and the discharge amount through the large-diameter discharge port is close to the preset value, and then the remaining powder weight is compensated through the compensation discharge port, which can effectively avoid that the discharge amount of the large-diameter discharge port is much larger or much smaller than the preset discharge amount, so as to improve the discharge accuracy of the powder. The feeding port 621 can be arranged on the top end or the side of the hopper 62. The vertical pipe 63 can effectively avoid material jamming.

[0065] Further, the rotary disc 2 includes a disc body 25, a second transmission shaft 26 and a motor 27; the second transmission shaft 26 is coaxial with the disc body 25, and the second transmission shaft 26 is arranged at the bottom end of the disc body 25; and the motor 27 is connected with the second transmission shaft 26. Specifically, the movement curve of the feeding port 21 during rotation is coaxial with the second transmission shaft 26, and the rotary disc 2 is rotated to rotate the semi-spherical shell 31 to the lower side of each hopper 62, collect the powder in the corresponding hopper 62 according to the proportioning requirement, and then rotate the semi-spherical shell 31 to the upper side of the stirring barrel 4 to discharge the powder. The rotary movement mode makes the rotary disc type multi-element precise proportioning device occupy a smaller space, and each powder is concentrated in the semi-spherical shell 31, which effectively avoids the interference of external dust and impurities and dust, and finally improves the proportioning accuracy of the mixed liquid.
