[0015] This invention also relates to a method for weighing and metering powder materials, applied to a powder material weighing and metering device, as detailed below:

[0016] S1: Equipment preparation and parameter setting;

[0017] Before weighing powder materials, the amount of material to be discharged each time is set through the touch screen. The rotation of the screw feeder is controlled by controlling the intermittent working time of the corresponding drive motor, thereby controlling the discharge amount of the discharge pipe.

[0018] S2: Quantitative discharge of powdered material;

[0019] The intermittently working drive motor drives the corresponding stirring component to rotate intermittently. The rotating stirring blades in the stirring component will drive the corresponding spiral feeding component to rotate intermittently, so that the discharge pipe discharges a certain amount of material. At the same time as the material is discharged, the rotating stirring blades will stir the material in the storage tank to prevent the powder inside the storage tank from clumping.

[0020] S3: The powder material is weighed and measured again for measurement.

[0021] When weighing powder materials, place the container for the material on the feeding platform directly below the discharge pipe to receive the material. After receiving the material, place the container for the material on the electronic scale again to weigh and test, thus completing the weighing and measurement operation of the powder materials.

[0022] The present invention has the following beneficial effects:

[0023] 1. The storage tank of this invention can be assembled into a single tank or a double tank. In the case of a single tank, the stirring shaft is spliced ​​together by a specific No. 1 plate, which is suitable for single-pipe discharge scenarios. In the case of a double tank, the stirring shaft is used separately on both sides by using a No. 2 plate with a partition, which enables double-pipe discharge. The two tanks can be loaded with the same or different powder materials for weighing and metering. In addition, when used in a dual-station configuration, the two stations can be used simultaneously or independently to meet different production needs.

[0024] 2. The feeding platform of this invention is equipped with an adjustment component. The No. 1 adjustment seat and the No. 2 adjustment seat cooperate through structures such as gear shafts and threaded levers to realize the overall height adjustment of the feeding platform, and can also adjust the height of the No. 1 and No. 2 feeding platforms individually to adapt to the loading vessels of different heights and improve the versatility of the equipment.

[0025] 3. Driven by the screw assembly, the present invention automatically separates the first and second stirring shafts, which is convenient to operate. Moreover, the lifting assembly in the top box drives the stirring assembly to rotate. During the discharge process, the stirring blades stir the powder material in the storage tank, effectively preventing powder agglomeration and ensuring smooth material discharge.

[0067] The gear shaft 602 of the second adjustment seat 632 has a rectangular groove 6022 on its outer side, and a rectangular protrusion 6021 is fixed on the outer side of the gear shaft 602 of the first adjustment seat 631. The size of the rectangular protrusion 6021 matches the size of the rectangular groove 6022.

[0068] The operation process of this embodiment is as follows: When in use, when the first adjustment seat 631 of the first material platform 610 and the second adjustment seat 632 of the second material platform 620 are in a docking state, the rectangular protrusion 6021 of the first adjustment seat 631 is inserted into the rectangular groove 6022 of the second adjustment seat 632. If it is necessary to adjust the height of the feeding platform 600 as a whole, one of the threaded levers 603 can be manually rotated in the forward or reverse direction to make the gear shaft 602 in the first adjustment seat 631 and the gear shaft 602 in the second adjustment seat 632 rotate synchronously. During this process, the movable sleeve 6013 in the first adjustment seat 631 and the movable sleeve 6013 in the second adjustment seat 632 move inward or outward synchronously, so that the height of the feeding platform 600 can be moved up or down synchronously to complete the operation of adjusting the height of the feeding platform 600 as a whole.

[0069] When the first adjusting seat 631 of the first material platform 610 and the second adjusting seat 632 of the second material platform 620 are in the separated state, if it is necessary to adjust the height of the first material platform 610 alone, simply manually rotate the threaded lever 603 in the first adjusting seat 631 in the forward or reverse direction, so that the gear shaft 602 in the first adjusting seat 631 rotates. During this process, the movable sleeve 6013 in the first adjusting seat 631 moves inward or outward, thereby raising or lowering the height of the first material platform 610, thus completing the operation of adjusting the height of the first material platform 610 alone. If it is necessary to adjust the height of the second material platform 620 alone, simply manually rotate the threaded lever 603 in the second adjusting seat 632 in the forward or reverse direction, so that the gear shaft 602 in the second adjusting seat 632 rotates. During this process, the movable sleeve 6013 in the second adjusting seat 632 moves inward or outward, thereby raising or lowering the height of the second material platform 620, thus completing the operation of adjusting the height of the second material platform 620 alone.

[0073] Furthermore, the No. 1 material platform 610 and the No. 2 material platform 620 are connected together by the adjustment component 630 to form an integrated unit.

[0074] The operation process of this embodiment is as follows: When the storage tank 300 is used as a single tank, first place a No. 1 plate 331 at the connection part of the No. 1 tank 310 and the No. 2 tank 320, ensuring that the threaded through hole on one side of the No. 1 plate 331 corresponds and overlaps with the threaded blind hole on the connection side of the No. 1 tank 310, and at the same time ensure that the threaded through hole on the other side of the No. 1 plate 331 corresponds and overlaps with the threaded blind hole on the connection side of the No. 2 tank 320. Then fix the screw into the overlapping threaded blind hole and threaded blind hole to complete the splicing of one side of the No. 1 tank 310 and the No. 2 tank 320. Then, in the same way as above, place another No. 1 plate 331 at the connection part of the No. 1 tank 310 and the No. 2 tank 320 and fix it to complete the assembly of the storage tank 300.

[0075] Next, align the discharge pipe 500 with the discharge port at the bottom of the storage tank 300, and then use screws to fix and install it, ensuring that the insert rod 501 in the spiral feeding assembly 510 inside the discharge pipe 500 is inserted into the second slot 302 in the middle part of the mixing assembly 340.

[0076] When the storage tank 300 is used as a single tank, the two No. 2 inserts 202 in the middle lifting assembly 230 are simultaneously inserted into the No. 1 slot 301 of the No. 1 stirring shaft 341 and the No. 1 slot 301 of the No. 2 stirring shaft 342. Through the action of the drive motor 233 in the middle part, the No. 1 stirring shaft 341 and the No. 2 stirring shaft 342 are driven to rotate as a whole, thereby driving the middle spiral feeding assembly 510 to rotate synchronously for single-pipe discharge.

[0077] Example 4

[0078] Please see Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 Based on Embodiments 1, 2, and 3, the storage tank 300 is a double-tank structure, and the sealing plate 330 is a second plate 332. A partition is welded in the middle of the second plate 332, and second fixing plates 3302 are welded to both sides of the second plate 332. Threaded through holes are provided on the outer side of the second fixing plates 3302. The threaded through holes on one side of the second plate 332 correspond one-to-one with the threaded blind holes on the connecting side of the first tank 310, and the threaded through holes on the other side of the second plate 332 correspond one-to-one with the threaded blind holes on the connecting side of the second tank 320. The first tank 310 and the second plate 332, as well as the second tank 320 and the second plate 332, are fixed together by the second fixing plates 3302 and screws. The first stirring shaft 341 and the second stirring shaft 342 are used separately on both sides. The first stirring shaft 341 is located inside the first tank 310, and the second stirring shaft 342 is located in the second tank. Inside body 320, the first insert 201 of the lifting assembly 230 on the left side is inserted into the first slot 301 on the top surface of the first stirring shaft 341, and the first insert 201 of the lifting assembly 230 on the right side is inserted into the first slot 301 on the top surface of the second stirring shaft 342. Two discharge pipes 500 are located at the bottom of the first tank body 310 and the bottom of the second tank body 320, respectively. One side of the top edge of the discharge pipe 500 on the left side is fixed to the tank seat 311 at the bottom of the first tank body 310 with screws, and the other side of the top edge of the discharge pipe 500 on the left side is fixed to the bottom of the second plate 332 with screws. One side of the top edge of the discharge pipe 500 on the right side is fixed to the tank seat 311 at the bottom of the second tank body 320 with screws, and the other side of the top edge of the discharge pipe 500 on the right side is fixed to the bottom of the second plate 332 with screws.

[0079] Specifically, the insert rod 501 in the spiral feeding assembly 510 inside the discharge pipe 500 on the left is inserted into the second slot 302 located on the bottom surface of the first stirring shaft 341, and the insert rod 501 in the spiral feeding assembly 510 inside the discharge pipe 500 on the right is inserted into the second slot 302 located on the bottom surface of the second stirring shaft 342.

[0080] Furthermore, the No. 1 material platform 610 and the No. 2 material platform 620 are used separately, with the No. 1 material platform 610 and the No. 2 material platform 620 located directly below the two discharge pipes 500 respectively.

[0081] The operation process of this embodiment is as follows: When the storage tank 300 is used as a double tank, the middle moving seat 231 and the drive motor 233 are first driven to the highest position by a set of hydraulic rods 232 of the middle lifting assembly 230. Then, the first seat 410 and the second seat 420 are driven to move to the outer side by the driving action of the screw assembly 132 on both sides, so that the first tank 310 and the second tank 320 move to the outer side. Then, the first stirring shaft 341 and the second stirring shaft 342 are manually moved to the outermost position. Then, the moving seats 231 and the drive motor 233 on both sides are driven to move to the lowest position by the hydraulic rods 232 of the lifting assembly 230 on both sides. This causes the first insert block 201 in the lifting assembly 230 on both sides to be inserted into the first slot 301 of the first stirring shaft 341 and the second stirring shaft 342 respectively.

[0082] Next, plate 332 is placed at the connection between tank 310 and tank 320, ensuring that the threaded through hole on one side of plate 332 corresponds to the threaded blind hole on the connecting side of tank 310, and at the same time, ensuring that the threaded through hole on the other side of plate 332 corresponds to the threaded blind hole on the connecting side of tank 320. Then, screws are fixed into the overlapping threaded blind holes to complete the assembly of storage tank 300. Through the partition in the middle of plate 332, storage tank 300 forms a double tank, which can be used in conjunction with the separated material platform 610 and material platform 620 for dual-station use. At this time, different powder materials can be loaded into tank 310 and tank 320 for weighing and metering, and the same powder materials can also be loaded into tank 310 and tank 320 for weighing and metering.

[0083] Next, align the two discharge pipes 500 with the two discharge ports at the bottom of the storage tank 300, and then fix them with screws to ensure that the insert rod 501 in the spiral feeding assembly 510 inside the left discharge pipe 500 is inserted into the second slot 302 on the bottom surface of the first stirring shaft 341, and the insert rod 501 in the spiral feeding assembly 510 inside the right discharge pipe 500 is inserted into the second slot 302 on the bottom surface of the second stirring shaft 342.

[0084] When the storage tank 300 is used as a double tank, the drive motors 233 on both sides drive the first stirring shaft 341 and the second stirring shaft 342 to rotate separately, thereby driving the spiral feeding components 510 on both sides to rotate synchronously for double-pipe discharge.

[0085] It should be noted that when the storage tank 300 is used as a dual-tank, both sides can either work synchronously with the motor 233 or work independently.

[0086] Example 5

[0087] This invention also relates to a method for weighing and metering powder materials, applied to a powder material weighing and metering device, as detailed below:

[0088] S1: Equipment preparation and parameter setting;

[0089] Before weighing the powder material, the amount of material to be discharged each time is set through the touch screen 120. By controlling the intermittent working time of the corresponding drive motor 233, the rotation of the screw feeding component 510 is controlled, thereby controlling the discharge amount of the discharge pipe 500.

[0090] S2: Quantitative discharge of powdered material;

[0091] The intermittently operating drive motor 233 drives the corresponding stirring component 340 to rotate intermittently. The rotating stirring blade 3401 in the stirring component 340 will drive the corresponding spiral feeding component 510 to rotate intermittently, so that the discharge pipe 500 discharges a certain amount of material. At the same time as the material is discharged, the rotating stirring blade 3401 will stir the material in the storage tank 300 to prevent the powder inside the storage tank 300 from clumping.

[0092] S3: The powder material is weighed and measured again for measurement.

[0093] When weighing powder materials, place the container for receiving the material on the discharge platform 600 directly below the discharge pipe 500. After receiving the material, place the container for receiving the material on the electronic scale 110 for weighing and testing again to complete the weighing and measurement operation of the powder materials.

The top side of the discharge pipe (500) on the right is fixed to the tank seat (311) at the bottom of the second tank (320) by screws, and the other side of the top side of the discharge pipe (500) on the right is fixed to the bottom of the second plate (332) by screws. The insert rod (501) in the spiral feeding assembly (510) inside the discharge pipe (500) on the left side is inserted into the second slot (302) on the bottom surface of the first stirring shaft (341), and the insert rod (501) in the spiral feeding assembly (510) inside the discharge pipe (500) on the right side is inserted into the second slot (302) on the bottom surface of the second stirring shaft (342). The No. 1 material platform (610) and the No. 2 material platform (620) are used separately, and the No. 1 material platform (610) and the No. 2 material platform (620) are respectively located directly below the two discharge pipes (500).

10. A method for weighing and measuring powder materials, characterized in that, The powder material weighing and metering device described in any one of claims 1 to 7 is specifically as follows: S1: Equipment preparation and parameter setting; Before weighing the powder material, the amount of material to be discharged each time is set through the touch screen (120). By controlling the intermittent working time of the corresponding drive motor (233), the rotation of the screw feeding assembly (510) is controlled, thereby controlling the discharge amount of the discharge pipe (500). S2: Quantitative discharge of powdered material; The intermittently working drive motor (233) drives the corresponding stirring component (340) to rotate intermittently. The rotating stirring blade (3401) in the stirring component (340) will drive the corresponding spiral feeding component (510) to rotate intermittently, so that the discharge pipe (500) discharges a certain amount of material. At the same time as the material is discharged, the rotating stirring blade (3401) will stir the material in the storage tank (300) to prevent the powder inside the storage tank (300) from clumping. S3: The powder material is weighed and measured again for measurement. When weighing powder materials, place the container for the material on the feeding platform (600) directly below the discharge pipe (500) to receive the material. After receiving the material, place the container for the material on the electronic scale (110) again to weigh and test, thus completing the weighing and measurement operation of the powder materials.
