[0035] The specific embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0036] Example

[0037] See also Figures 1 to 7The utility model discloses a weighing device for multiple rotating dispersed materials, a preferred embodiment of which comprises a base unit 100, a feeding unit 200, a central column driving unit 300, a combined feeding unit 400, a feeding hopper 500, a measuring hopper 600 and a collecting hopper 700. The base unit 100 is the support of the entire weighing device, and other units of the weighing device, such as the feeding unit 200, the central column driving unit 300, the combined feeding unit 400 and the collecting hopper 700 are all mounted and fixed on the base unit 100.

[0038] The central column driving unit 300 is fixed on the base unit 100. Multiple combined feeding units 400 weigh and measure materials at the same time, and are the core functional units of the device. They are fixed on the base unit 300, surrounding the center 300 of the central column driving unit, and symmetrically distributed around the central column driving unit 300. The central column driving unit 300 drives these combined feeding units 400 to move at the same time, thereby completing the material weighing and metering actions. The feeding unit 200 is located above all the combined feeding units 400, and it is also connected to the central column driving unit 300. The feeding unit 200 distributes the materials to different combined feeding units 400. Below each combined feeding unit 400, there are separate feeding hoppers 500 and metering hoppers 600 in sequence. Each combined feeding unit 400 corresponds to a feeding hopper 500 and a metering hopper 600. A collecting bucket 700 is installed below all the measuring buckets 600, which collects and concentrates the materials output by multiple measuring buckets 600, so as to obtain accurate measured output.

[0039] See especially Figure 1 and Figure 2 In this embodiment, the base unit 100 is composed of a support frame 110, a support leg 120 and a chute 130. The support frame 110 is a rectangle with a central opening, and two support legs 120 are fixed below the four right angles of the support frame 110 to support the support frame 110. The chute 130 is funnel-shaped, which passes through the opening set in the middle of the support frame 110, rests on the support frame 110, and is then fixed on the support frame 110. The collecting bucket 700 is connected and fixed to the support leg 120, which is located below the outlet of the chute 130 and receives the materials from the chute 130. On the upper plane of the chute 130, a disc-shaped first connecting mechanism 140 is set.

[0040] See especially Figure 1 and Figure 3In this embodiment, the feed unit 200 is a silo with a top cone and is circular. At the center of the circle is a raised top cover, and a plurality of openings are arranged around the edge. The feed unit 200 is located above the combined feeding unit 300, and each of its openings corresponds to the entrance of a combined feeding unit 300 below it. Because the feed unit 200 is circular, and the combined feeding unit 300 is arranged symmetrically along the circumferential direction, the material from the upper-level equipment will be relatively evenly guided to different combined feeding units 300 after falling into the feed unit 200, thereby ensuring the accuracy of weighing and metering. At the center of the feed unit 200, a sweeping rod 210 is provided to sweep the material from the center into the opening located at the edge. Below the feed unit 200, a cylindrical second connecting mechanism 220 is connected and fixed to the first connecting mechanism 140 above the chute 130, so that the feed unit 200 is fixedly connected to the base unit 100.

[0041] See especially Figure 1 and Figure 4 In this embodiment, the center column driving unit 300 includes multiple groups of connecting rod driving devices 310. It uses the center column as a frame and is mounted on the second connecting mechanism 220 of the feeding unit 200 using the central circular hole 320. Each group of connecting rod driving devices 310 corresponds to a combined feeding unit 400. Under the drive of the motor with a reduction gear, the lever on the motor shaft is used as an actuator to drive the scraper device in the feeding hopper 500 and the measuring hopper 600 to operate, thereby releasing the materials that meet the weighing and metering requirements into the collecting hopper 700.

[0042] See especially Figure 1 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the combined feeding unit 400 is composed of an inner screw module 410, an outer rotating tube module 420, a mounting bracket 430, a mounting base 440, and a silo 450. The silo 450 is located at the uppermost end of the combined feeding unit 400, and it is fixed to the mounting base 440 together with the inner screw module 410 and the outer rotating tube module 420 through the mounting bracket 430. The mounting base 440 is connected and fixed to the central column driving unit 300.

[0043] The opening of the silo 450 is fixed on the mounting base 440, and its entrance corresponds to the opening position on the circumferential edge of the feeding unit 200, and receives the material distributed relatively evenly by the feeding unit 200. The outlet of the silo 450 is composed of an inner screw module 410 and an outer rotary tube module 420 to form a feeding mechanism. Among them, the inner screw module 410 is composed of an inner screw 411 and a first drive motor 412. The first drive motor 412 is fixedly connected to the mounting bracket 430 and is located on the side of the silo 450 close to the central column drive unit 300. The output shaft of the first drive motor 412 is driven and connected to one end of the inner screw 411. On the one hand, it fixes the inner screw 411, and on the other hand, it can also drive the inner screw 411 to rotate. The outer rotary tube module 420 is composed of an outer rotary tube 421 and a second drive motor 422. The outer rotary tube 421 is fixed to the mounting base 440 through the mounting bracket 430, and is attached to one side of the silo 450, and can rotate along the axial direction. The second drive motor 422 is fixedly connected to the mounting bracket 430, and is located on the side of the silo 450 away from the center column drive unit 300, and is used to drive the outer rotating tube 421 to rotate. The outer diameter of the inner screw 411 matches the inner diameter of the outer rotating tube 421, and is mounted inside the outer rotating tube 421, and can rotate independently. The outer rotating tube 421 serves as the outlet of the silo 450, guiding the material to flow out of the silo 450. During the outflow of the material, the outer rotating tube 421 and the inner screw 411 rotate differentially under the drive of the second drive motor 422 and the first drive motor 412 respectively, wherein the rotation speed of the outer rotating tube 421 is slightly faster than that of the inner screw 411, thereby ensuring that the material does not stick to the tube wall during the transmission process, and ensuring the accuracy of weighing and metering.

[0044] See especially Figure 1 , Figure 8 and Fig. 9 , the feeding hopper 500 and the measuring hopper 600 are driven by the central column driving unit 300 and work in cooperation with the central column driving unit 300. The inlet of the feeding hopper 500 is upwardly installed below the end of the outer rotary tube module 420 away from the silo 450, and is used to receive materials from the silo 450. In order to ensure that the viscous material does not stick to the outlet of the feeding hopper 500 and affect the weighing and metering, a first scraper 510 is set at the outlet of the feeding hopper 500. The first scraper 510 is connected to the central column driving unit 300 and is driven by the central column driving unit 300. The inlet of the measuring hopper 600 is upwardly installed below the outlet of the feeding hopper 500, and is used to receive materials from the feeding hopper 500. Similarly, in order to ensure that the viscous material does not stick to the outlet of the measuring hopper 600 and affect the weighing and metering, a second scraper 610 is set at the outlet of the measuring hopper 600. The second scraper 610 is connected to the central column driving unit 300 and is driven by the central column driving unit 300. The outlet of the measuring hopper 600 matches the position of the chute 130 in the base unit 100. The material leaving the measuring hopper 600 passes through the chute 130 and enters the collecting hopper 700.

[0045] See especially Figure 1 and Fig.10 The collecting bucket 700 includes a collecting bucket 710 and a collecting bucket flat plate 720, which are used to collect and aggregate materials from multiple combined feeding units 400, and then deliver the materials with accurate total weight to the next level of equipment. The collecting bucket 710 is fixed on the collecting bucket flat plate 720, and the collecting bucket flat plate 720 is fixed to the four legs 120 of the frame 110 in the base unit 100. The collecting bucket 710 is located below the chute 130, and it collects the materials from the chute 130 together and then outputs them from the outlet below. In order to ensure that the sticky materials do not stick to the outlet of the collecting bucket 710 and affect the weighing and metering, a third scraper 730 is set at the outlet of the collecting bucket 710. The third scraper 730 is connected to the collecting bucket flat plate 720 through a cylinder 740, and its opening and closing are controlled by the cylinder 740.

[0046] The following is a brief description of the working process of the weighing device of the utility model for multiple rotating dispersed materials: when the material from the feed unit 200 is sent to the combined feeding unit 400, the two drive motors (the first drive motor 412 and the second drive motor 422) in the combined feeding unit 400 respectively drive the inner screw 411 and the outer spiral tube 421 to operate at different speeds. According to different materials, different parameters are adjusted to make the material output more stable and uniform, and then the weight is combined through the feeding hopper 500 and the metering hopper 600, and then the weighed material is sent to the next process in combination with the chute 130 and the collection hopper 710. Scrapers (the first scraper 510, the second scraper 610 and the third scraper 730) are set at each relevant hopper outlet to ensure that the sticky material can pass completely without residue.

[0047] The specific working principle is as follows: when the feed hopper 500 is empty, the combined feed unit 400 transports the material from the combined feed unit 400 to the feed hopper 500 at a set time. When the weighing hopper 600 below the feed hopper 500 is empty after discharging the material, the feed hopper 500 opens and discharges the material into the weighing hopper 600, and the weighing hopper 600 starts weighing again.

[0048] Assume that our target weight is 250g, and we take a combination of 5 buckets (that is, take the sum of the five buckets as the result). Then there are 5 feeding hoppers 500 and 5 measuring hoppers 600 involved in the weighing, for a total of 10 buckets. There are 252 ways to take 5 buckets out of these 10 buckets. First, when setting the vibration time of the feeding unit 200, 50g is used as the target weight of each bucket, so that the material vibrated will be around 50g. However, since the materials are of different sizes and quantities, and are not very uniform, the weight of each bucket will vary, but it will be around 50g: there will be both heavy buckets and light buckets. Then, according to the weighing of the measuring bucket 600, one of the 252 methods is selected, so that the probability that the weight of the 5 buckets adds up to 250g is very high, and accurate weighing can be achieved. In this process, the combined feeding unit 400 needs to be able to deliver the material from the feeding unit 200 completely into the feeding hopper 500 of the next level to meet the requirement of "the weight of each hopper is around 50g", so the material transmission in the combined feeding unit 400 is extremely important.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, any equivalent changes and modifications made according to the content of the patent application scope of the present invention should be within the technical scope of the present invention.
