Description

Technical Field

[0001] The utility model relates to the technical field of automatic powder processing, in particular to a quantitative powder feeding structure for automatic powder processing equipment. Background Art

[0002] In the automatic powder processing process, the powder is usually unpacked and screened before being unloaded to continue the subsequent process. If there is a demand for particle diameter, it is necessary to unpack, grind and screen before unloading to continue the subsequent process. Usually these processes are integrated on one device to form an automatic powder processing device. However, the processing involves not only the processing of one type of powder, but also the mixing of multiple powders, or the mixing of powders with other raw materials. Before the mixing process, the amount of each powder has a quantitative requirement. Some equipment is quantitative by controlling the opening time of the valve of the equipment discharge port, but this method is not very accurate. There are also equipment that uses a discharge plate with a built-in groove that can be rotated. The powder capacity inside the groove is the rated amount. The groove is connected to the upper part, and the groove is turned to the lower part to discharge the material, so as to realize quantitative powder discharge. However, this method can only be rated for one quantity value. When the required powder demand changes, it cannot be adjusted to meet the change of the rated quantity of powder.

[0028] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0029] Example 1

[0030] See also Figure 1-2 This embodiment introduces a quantitative powder feeding structure for automatic powder processing equipment, which is mainly composed of an equipment body 1, a motor 2, a quantitative component 3, and a partition 4. The equipment body 1 may include a casing, an unpacking structure, a splitting structure, a filtering structure, etc., and may also include other structures, which are arranged according to the automatic powder processing process. The motor 2 adopts a forward and reverse motor to drive the forward and reverse rotation of the quantitative component 3. The feeding port of the equipment body 1 is located at the bottom thereof, and the motor 2 is installed on the outer wall of the feeding port of the equipment body 1, and can be fixed to the outside of the feeding port of the equipment body 1 by a bracket or other mounting accessories.

[0031] The quantitative component 3 is mainly composed of a disc 31 and a telescopic member 32. The disc 31 has a shaft at the center of the circle. The maximum cross-sectional area of ​​the disc 31 is consistent with the cross-sectional area of ​​the feeding port. Therefore, the disc 31 is located in the feeding port and just fits the inner wall of the feeding port to close the feeding port. The outer circumference of the disc 31 is provided with a groove 311 along the center direction to store powder. The overall shape of the groove 311 is rectangular, and the bottom is through-set. The telescopic member 32 is installed at the bottom of the groove 311 to close the bottom of the groove 311.

[0032] The telescopic member 32 mainly includes a bottom plate 321, a telescopic cylinder 322, a baffle 323 and a distance sensor 324. The bottom plate 321 is located in the groove 311 and is detachably connected to the disc 31. The bottom plate 321 and the disc 31 can be connected together by means of embedded bolts, screws, etc. The outer wall of the bottom plate 321 is arc-shaped and fits the outer peripheral edge of the disc 31. The bottom plate 321 closes the bottom of the groove 311. In order to improve the connection sealing between the bottom plate 321 and the groove 311, a flexible pad is bonded around the bottom plate 321. The elastic material such as silicone can be used. The gap between the bottom plate 321 and the groove 311 is filled by compressing the flexible pad to achieve the purpose of completely closing the bottom of the groove 311.

[0033] The part of the bottom plate 321 located inside the groove 311 is connected to the fixed end of the telescopic cylinder 322, and the movable end of the telescopic cylinder 322 is connected to the baffle 323. The baffle 323 fits the inner wall of the groove 311, dividing the groove 311 into two parts, the upper and lower parts. The powder cannot enter the space enclosed by the bottom of the baffle 323 and the top of the bottom plate 321. The part of the groove 311 at the top of the baffle 323 is used to accommodate the powder. The movement of the baffle 323 can change the space of the groove 311 used to accommodate the powder. The bottom of the baffle 323 is provided with a distance sensor 324 for sensing the distance from the bottom plate 321, which serves as a reference to assist the telescopic cylinder 322 in controlling the telescopic distance of the baffle 323. The bottom corner of the baffle 323 is chamfered to reduce the contact area with the groove 311.

[0034] When the space for accommodating the powder in the groove 311 needs to be increased, the telescopic cylinder 322 is driven to move the baffle 323 downward, and vice versa, the baffle 323 is driven to move upward. In the initial state, the groove 311 faces upward to the inside of the equipment body 1, and the powder enters the groove 311. The motor 2 drives the disc 31 to rotate, so that the groove 311 changes from an upward state to a downward state, and the powder in the groove 311 is discharged along the discharge port to achieve quantitative discharge.

[0035] like Figure 3 As shown, in order to facilitate the rotation of the disc 31 and reduce the impact of the powder on the disc 31, a partition 4 is arranged at the top of the discharge port of the equipment body 1. The partition 4 is located above the disc 31 and is rectangular as a whole. The edge of the disc 31 is blocked, and the partition 4 is inclined from the outside to the inside, so that the powder can be guided into the groove 311. A soft brush 41 for intercepting the powder is fixedly connected to the inner side of the partition 4. The soft brush 41 will be in contact with the soft brush 41 when the disc 31 rotates. The soft brush 41 intercepts part of the powder without affecting the normal rotation of the disc 31.

[0036] The existence of the partition 4 can intercept some powders, but some powders will still enter the gap between the disk 31 and the feeding port, affecting the normal rotation of the disk 31. Therefore, a plurality of through holes 11 at the same height are opened on the surface of the feeding port, and the through holes 11 are connected to the chamber surrounded by the partition 4 and the disk 31. A powder suction member 5 is arranged outside the through hole 11 to suck out the powder in the gap between the disk 31 and the feeding port, thereby ensuring the normal rotation of the disk 31.

[0037] The powder suction part 5 mainly includes a square tube 51, an air suction pump 52 and a storage box 53. The square tube 51 is installed on the outer wall of the discharge port of the equipment body 1, wraps the through hole 11 and is connected with the through hole 11; the square tube 51 is connected with the storage box 53 through a pipeline, and the air inlet end of the air suction pump 52 is connected with the storage box 53. It should be noted that a filter is provided at one end of the air suction pump 52 connected to the storage box 53, which can intercept the powder from being discharged from the air suction pump 52. The air suction pump 52 inhales air, and the powder in the gap between the disc 31 and the discharge port enters the storage box 53 through the through hole 11 and the square tube 51, and the storage box 53 can be cleaned regularly.

[0038] This embodiment increases the applicable scope of the quantitative feeding structure by changing the storage space for storing powder in the groove 311 to adapt to the change in the rated quantity of powder, and the structure is simple; in addition, the partition 4 is used to block the top space of the disc 31 to reduce the accumulation of powder in the gap between the disc 31 and the equipment body 1, so that the disc 31 can rotate normally.

[0039] Example 2

[0040] like Figure 4 As shown, this embodiment introduces a quantitative powder feeding structure for automatic powder processing equipment, which is basically the same as the quantitative powder feeding structure for automatic powder processing equipment introduced in Example 1. The difference is that the two symmetrical sides of the groove 311 of the disk 31 of this embodiment away from the shaft begin to expand outward from the middle section to form an outward expansion part, and the side wall of the baffle 1 323 is in contact with the inner wall of the outward expansion part of the groove 311. The outward expansion part can increase the accommodation space of the groove 311. The baffle 1 323 moves in the outward expansion area, and the capacity of the groove 311 can be changed by moving a short distance.

[0041] This embodiment has the same beneficial effects as Embodiment 1.

[0042] Example 3

[0043] like Figure 5 As shown, this embodiment introduces a quantitative powder discharge structure for automatic powder processing equipment, which is basically the same as the quantitative powder discharge structure for automatic powder processing equipment introduced in Example 2. The difference is that one of the outward expansion parts of the groove 311 of the disc 31 of this embodiment is set through along the outward expansion direction. And the telescopic member 32 is mainly composed of a side plate 301, a telescopic cylinder 302 and a baffle 303. The side of the groove 311 is detachably connected to the side plate 301 to close the side of the groove 311. A plurality of telescopic cylinders 302 are connected to the side plate 301. The movable end of the telescopic cylinder 302 is connected to the baffle 303. The plurality of baffles 303 are arranged adjacent to each other and fit the inner wall of the groove 311, blocking the telescopic cylinder 302 and the space for accommodating the powder in the groove 311.

[0044] Multiple baffles 303 are arranged from top to bottom. At first, baffle 303 is located in the middle of groove 311, but it can still block the powder from entering the space between baffle 303 and side plate 301. When the space for accommodating powder needs to be expanded, telescopic cylinders 302 are driven from top to bottom to move the baffles toward side plate 301. That is, during the initial expansion, the top baffle 303 is driven toward side plate 301, and then driven downward in sequence until all baffles 303 are contracted to reach the maximum accommodating space.

[0045] This embodiment has the same beneficial effects as Embodiment 2.

[0046] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
