Description

Technical Field

[0001] The utility model relates to the technical field of testers, in particular to a full-automatic dry powder fluidity tester. Background Art

[0002] The working principle of the full-automatic dry powder fluidity tester is mainly based on the measurement of the flow rate and particle size distribution of the powder. During the test, the instrument places the dry powder sample in the measuring container and makes the dry powder flow in the container by controlling certain pressure or gravity conditions. At the same time, the instrument uses measurement technologies such as laser velocity measurement technology or load cells to monitor and record the flow rate of the dry powder in real time.

[0003] Before using the dry powder fluidity tester to test the fluidity of the dry powder, it is often necessary to adjust the height of the funnel. At present, the dry powder fluidity testers on the market often adjust the height of the funnel through bolts. During the adjustment process, the bolts need to be loosened first, and then the bolts are rotated to lock them after the height of the funnel is adjusted. This adjustment method has relatively cumbersome steps and is very troublesome, which is not conducive to the use of users. Therefore, there is an urgent need for a dry powder fluidity tester that can quickly adjust the height of the funnel. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a full-automatic dry powder fluidity tester to solve the disadvantages existing in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] In addition, a preferred structure is that a secondary cavity is opened at the rear of the adjustment cavity inside the mounting plate, the size of the secondary cavity is smaller than that of the adjustment cavity and is communicated with it.

[0008] In addition, a preferred structure is that a plurality of springs are installed on the side of the secondary cavity far away from the adjustment cavity, and the other ends of the springs are all connected to the adjustment plate.

[0009] In addition, a preferred structure is that through holes are opened on the side of the adjustment cavity facing the column corresponding to the limit columns, and the through holes are adapted to the limit columns.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Refer to Figures 1-4, A fully automatic dry powder fluidity tester, which includes a tester body 1. On one side of the tester body 1, a vertical column 2 is fixedly arranged. Two rows of limiting holes 21 are vertically opened at the rear of the vertical column 2. An installation plate 3 is vertically movably arranged on the vertical column 2, and a funnel assembly 4 is fixedly arranged on the installation plate 3. An adjustment cavity 31 is opened inside the installation plate 3. An adjustment plate 5 is movably arranged in the adjustment cavity 31. On both sides of the adjustment plate 5, limiting columns 51 are fixedly arranged, and the limiting columns 51 are all adapted to the limiting holes 21. Among them, through the settings of the tester body 1 and the funnel assembly 4, the automatic test of the dry powder fluidity can be realized. And it is worth noting that the specific structures, working methods and usage methods of the tester body 1 and the funnel assembly 4 are all existing technologies that have been publicly available on the market at present. They are all common knowledge well-known to those skilled in the art and do not belong to the main technical problems to be solved in this technical solution. Therefore, they will not be elaborated in this utility model.

[0020] Among them, a secondary cavity 32 is opened at the rear of the adjustment cavity 31 inside the installation plate 3. The size of the secondary cavity 32 is smaller than that of the adjustment cavity 31 and is communicated with it. On the side of the secondary cavity 32 away from the adjustment cavity 31, a plurality of springs 7 are installed, and the other ends of the springs 7 are all connected to the adjustment plate 5. Through the setting of the springs 7, the pushing of the adjustment plate 5 can be realized, so that the limiting columns 51 on the adjustment plate 5 can be stably clamped with the adjustment cavity 31.

[0021] Among them, through holes corresponding to the limiting columns 5 are opened on the side of the adjustment cavity 31 facing the vertical column 2, and the through holes are adapted to the limiting columns 5. This can enable the limiting columns 51 to extend out of the adjustment cavity 31 and be inserted into the limiting holes 21.

[0022] Among them, the width and height of the adjustment plate 5 are adapted to those of the adjustment cavity 31, and the length of the adjustment cavity 31 is greater than the length of the limiting column 51. This can ensure that the adjustment plate 5 slides smoothly inside the adjustment cavity 31.

[0023] Among them, an adjustment rod 6 is fixedly and vertically arranged on the side of the adjustment plate 5 facing the spring 7. The adjustment rod 6 extends out of the installation plate 3, and an adjustment handle 61 is fixedly arranged at the end of the adjustment rod 6 extending out of the installation plate 3. Through the settings of the adjustment rod 6 and the adjustment handle 61, it is convenient for the user to move and adjust the adjustment plate 5.

[0024] In this utility model, when the user needs to adjust the height of the installation plate 3 and the funnel assembly 4, the adjustment rod 6 can be pulled outwards through the adjustment handle 61. At this time, the adjustment plate 5 and the limiting column 51 can be driven to move outwards through the adjustment rod 6. At this time, the spring 7 is compressed by the extrusion of the adjustment plate 5, and the limiting column 51 leaves the inside of the limiting hole 21. At this time, the clamping between the limiting column 51 and the limiting hole 21 is released, and the user can then adjust the height of the installation plate 3 by moving it up and down.

[0025] Further, after the user finishes adjusting the height of the mounting plate 3, the adjusting handle 61 can be loosened, and then the mounting plate 3 can be slightly moved up and down. When the limiting post 51 is aligned with the limiting hole 21, the adjusting plate 5 and the limiting post 51 will move outwards by the elastic force of the spring 7, so that the limiting post 51 can move into the limiting hole 21 again and be engaged with it. At this time, the adjustment of the height of the mounting plate 3 and the funnel assembly 4 is completed, and the operation steps are relatively convenient, which is convenient for the user to use.

[0026] In the present utility model, the test of the fluidity of the dry powder can be realized through the setting of the tester body 1 and the funnel assembly 4. During the preparation for the test, through the setting of the adjusting plate 5 and the adjusting rod 6, the height of the funnel assembly 4 can be quickly adjusted. The operation steps of this adjustment method are relatively simple, which is convenient for the user to use.

[0027] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
