Description

Technical Field

[0001] This utility model belongs to the field of powder distribution technology, and in particular relates to a high-precision powder metering and dispensing device. Background Technology

[0002] High-precision powder refers to industrial raw materials made by mixing and dispersing powdered raw resin with various additives after advanced refining, resulting in smaller and finer particles.

[0003] In the production of high-precision powders, various additives need to be added in precise quantities. Precise metering and distribution are required to ensure the stability of the production process and the controllability of product quality, thereby ensuring the accurate proportion of each raw material and improving the quality and consistency of the final powder. However, during distribution, because the powder is concentrated in one place, the top of the powder is not flat, causing a deviation in its center of gravity. This results in uneven pressure on the weighing sensor, causing it to shift or vibrate, which in turn affects the accuracy of the weighing sensor, leading to inaccurate measurement results and affecting the precision of the final powder.

[0004] Therefore, how to provide a high-precision powder metering and dispensing device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The diagram shown is a structural schematic of a high-precision powder metering and dispensing device according to an embodiment of the present invention, comprising:

[0033] First support frame 1;

[0034] Touch screen 17 is fixedly installed on the front side of the bottom of the first support frame 1;

[0035] Positioning frame 2 is fixedly installed on the front side of the top of the first support frame 1;

[0036] Placement frame 4 is movably inserted into the middle of positioning frame 2;

[0037] A high-precision weighing sensor 9 and an array of high-precision weighing sensors 9 are placed at the bottom of the placement frame 4, and a weight display screen 13 is provided on the side.

[0038] Material cup 8, the array of material cups 8 is placed inside the placement frame 4 and is in active contact with the top of the high-precision weighing sensor 9;

[0039] The centrifugal structure is located on the rear side of the positioning frame 2, which drives the material cup 8 to rotate and flatten.

[0040] In this embodiment of the utility model, when in use, the first support frame 1 is installed in a predetermined place, and then the weight of the powder put into the bottom of the placement frame 4 by the touch screen 17 is adjusted. Then the centrifugal structure is started intermittently so that the powder in the material cup 8 is flattened. Then the material cup 8 stops rotating, and the powder in the material cup 8 can be weighed with high precision by the high precision weighing sensor 9, and then displayed on the corresponding weight display screen 13.

[0041] By setting a centrifugal structure on the positioning frame 2, the corresponding material cup 8 in the placement frame 4 is rotated, thereby generating centrifugal force in the material cup 8, which flattens the powder in the material cup 8. This makes it easier for the high-precision weighing sensor 9 to weigh the powder in the material cup 8 with high precision, thereby reducing the occurrence of weighing errors.

[0042] like Figure 1 , Figure 2 and Figure 3As shown, in a preferred embodiment of the present invention, the positioning frame 2 is symmetrically provided with a compaction structure on both sides. The compaction structure includes a support plate 20, a second support frame 22 and a pressure plate 24. The support plate 20 is symmetrically installed on both sides of the positioning frame 2, and a storage groove 21 is opened at the lower end. The pressure plate 24 is movably placed inside the storage groove 21 and is correspondingly arranged with the material cup 8 below. The second support frame 22 is fixedly installed on the top of the support plate 20, and a multi-stage telescopic rod 23 is provided on the surface, which is fixedly connected to the middle of the top of the pressure plate 24.

[0043] In this embodiment of the utility model, when the material cup 8 containing powder moves below the support plate 20, the multi-stage telescopic rod 23 on the second support frame 22 at the top of the support plate 20 is activated, thereby causing the pressure plate 24 in the storage groove 21 at the lower end of the support plate 20 to extend and enter the material cup 8, thereby pressing the powder in the material cup 8 flat.

[0044] By setting up a compaction structure, the powder in the material cup 8 can be compacted, thereby improving the stability of the powder and preventing leakage due to bumps during transportation.

[0045] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment of the present invention, the centrifugal structure includes an adjusting gear 19, a second toothed groove 10, and a movable groove 15. The second toothed groove 10 is located in the middle of the material cup 8. An adjusting toothed roller 18 is provided in the middle of the rear side of the positioning frame 2 and is engaged with the second toothed groove 10. The movable groove 15 is located in the rear side of the positioning frame 2 and is provided with an electric rotating rod 16 in the middle. The adjusting gear 19 is fixedly installed at the bottom of the movable groove 15 and is engaged with the adjusting toothed roller 18.

[0046] In this embodiment of the utility model, when in use, the electric rotary rod 16 is intermittently started, and then the adjusting gear 19 at the bottom of the electric rotary rod 16 drives the adjusting tooth roller 18 to rotate, and then drives the material cup 8 to rotate through the second tooth groove 10.

[0047] By setting up a centrifugal structure, the powder in the material cup 8 is flattened under the influence of centrifugal force, which facilitates the high-precision weighing sensor 9 to weigh the powder in the material cup 8 with high precision and reduces the occurrence of weighing errors.

[0048] like Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, in a preferred embodiment of the present invention, the bottom of the positioning frame 2 is also provided with a driving structure. The driving structure includes a first tooth groove 5, a toothed disc 6 and a motor 7. The first tooth groove 5 is opened at the bottom of the placement frame 4. The motor 7 is fixedly installed at the bottom of the positioning frame 2. The toothed disc 6 is disposed inside the first tooth groove 5 and meshes with one side of the first tooth groove 5. The toothed disc 6 is fixedly connected to the motor 7.

[0049] In this embodiment of the utility model, when in use, the motor 7 at the bottom of the positioning frame 2 is started, which causes the toothed disk 6 in the first toothed groove 5 to rotate, thereby changing the length of the placement frame 4 extending out of both sides of the positioning frame 2 through the engagement of the first toothed groove 5.

[0050] By setting up a driving structure, it is easier to control and adjust the length of the placement frame 4 extending from both sides of the positioning frame 2, thereby facilitating the removal and placement of the material cup 8.

[0051] like Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the pressure plate 24 is circular, and the diameter of the pressure plate 24 is equal to the inner diameter of the material cup 8.

[0052] In this embodiment of the utility model, when in use, the pressure plate 24 is set to be circular, and the diameter of the pressure plate 24 is equal to the inner diameter of the material cup 8, so that the powder in the material cup 8 can be compacted when the pressure plate 24 descends.

[0053] like Figure 1 As shown, in a preferred embodiment of the present invention, the two sides of the placement frame 4 are arrayed with openings 14, and the side of the positioning frame 2 is provided with through holes 3.

[0054] In this embodiment of the utility model, when in use, openings 14 are arrayed on both sides of the first support frame 1 to facilitate the removal of the material cup 8, and through holes 3 are provided on the side of the positioning frame 2 to facilitate the viewing of the weight display screen 13 inside the positioning frame 2 through the through holes 3.

[0055] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the top of the positioning frame 2 is fixedly installed with a delivery port 11, and the lower end of the delivery port 11 is movably provided with a through-and-break partition 12.

[0056] In this embodiment of the utility model, when in use, a feeding port 11 is fixedly installed on the top of the positioning frame 2, and a switch plate 12 is movably provided at the lower end of the feeding port 11, thereby facilitating the control of the material entry and exit time.

[0057] The above embodiments of this utility model provide a high-precision powder metering and dispensing device. When in use, the first support frame 1 is installed in a predetermined position, and then the weight of the powder dispensed by each high-precision weighing sensor 9 at the bottom of the placement frame 4 is adjusted by the touch screen 17.

[0058] Then, connect the feeding port 11 to the conveying pipe, and then activate the on / off baffle 12 to open the feeding port 11, so that the powder can be fed into the material cup 8 through the feeding port 11.

[0059] Subsequently, the electric rotary rod 16 in the active slot 15 is intermittently started, and the adjusting gear 19 at the bottom of the electric rotary rod 16 drives the adjusting tooth roller 18 to rotate. Then, through the second tooth groove 10 in the middle of the material cup 8, the material cup 8 is driven to rotate, and under the influence of centrifugal force, the powder in the material cup 8 is flattened.

[0060] When the electric rotary rod 16 is stopped, the material cup 8 no longer moves, which allows the high-precision weighing sensor 9 at the bottom of the frame 4 to weigh the powder in the material cup 8 with high precision and display it on the corresponding weight display screen 13.

[0061] When the weight of the powder in the material cup 8 reaches the required level, the motor 7 at the bottom of the positioning frame 2 is started, which causes the toothed disc 6 in the first toothed groove 5 to rotate. Through the cooperation of the first toothed groove 5, the length of the placement frame 4 extending out of the positioning frame 2 on both sides changes.

[0062] When the material cup 8 containing the powder moves below the support plate 20, the multi-stage telescopic rod 23 on the second support frame 22 at the top of the support plate 20 is activated, causing the pressure plate 24 in the storage groove 21 at the lower end of the support plate 20 to extend and enter the material cup 8, thereby flattening the powder in the material cup 8. When it moves out from below the support plate 20, the material cup 8 can be taken out through the opening 14. Because the powder is flattened, the stability of the powder is improved, thus avoiding leakage of material due to bumps during transportation.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
