Abstract
Description
Technical Field
[0001] This utility model relates to the field of resin soft knife raw material testing, specifically to a resin powder flowability testing fixture. Background Technology
[0002] In the manufacturing of flexible blades, one type is made by heating and pressing resin powder, diamond, binder, and auxiliary abrasives to form blades with specific parameters; this is called a resin flexible blade. This process requires selecting suitable resin powder, controlling its flowability during heating, and ensuring consistent spacing between the raw materials to meet specifications. Selecting the right resin powder necessitates understanding its flow parameters beforehand. Currently, the flowability testing of resin powder relies on controlling the pressing height and thickness of each resin pellet before heating. However, at the same temperature, the flow direction of each resin pellet can differ, resulting in upward, rightward, or both, and irregular flow patterns. This unevenness in powder spacing makes it impossible to measure specific data, thus affecting the selection of resin powder and consequently impacting the production efficiency of the flexible blade. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of existing testing processes where, under the same temperature, each resin pellet has a different flow direction, resulting in upward, rightward, or both upward and rightward flow, or irregular flow, leading to uneven powder gaps and making it impossible to measure specific data. This invention provides a resin powder flowability testing fixture that ensures that there is only one variable when the resin powder is heated, serving as the testing standard, so that the powder is evenly distributed and the resin flows in a specific direction, thus solving the problems of the prior art.
[0004] To achieve the above and other objectives, this utility model provides a resin powder flowability testing fixture, which includes:
[0005] The box has a receiving cavity inside;

The upper pressure plate is located at the upper part of the receiving cavity, and the left and right pressure plates are located on both sides of the bottom of the receiving cavity of the box.
[0007] A rotating rod is provided on one side of the pressure plate. The rotating rod includes an upper rotating rod, a left rotating rod, and a right rotating rod, and passes through the housing.
[0008] In some embodiments, the top surface of the enclosure is a glass plate, and the remaining surfaces are made of heat-resistant aluminum.
[0009] In some embodiments, the glass plate is provided with horizontal and vertical scale lines that intersect at one vertex of the box.
[0010] In some embodiments, the rotating rod is provided with a rotating rod handle on one side of the casing exterior.
[0011] In some embodiments, the rotating rod is provided with a first thread, and the housing is provided with a second thread that is adapted to the first thread.
[0012] In some embodiments, the left pressure plate and the right pressure plate have the same length and width, the upper pressure plate has a longer length than the left pressure plate, and the upper pressure plate has a thicker thickness than the left pressure plate.
[0013] In some embodiments, the resin powder flowability testing fixture includes a bump handle disposed on the upper part of the glass plate.
[0014] This utility model provides a resin powder flowability testing fixture. Compared with the prior art, this utility model has the following beneficial effects: The resin powder flowability testing fixture provided by this utility model can realize the detection and comparison of different resins under the same conditions, or the same resin under different conditions.

Rotate the upper rotating rod 31 to adjust the upper pressure plate 21 to a position close to the box body 1. Place it in the sintering furnace, and observe the changes through the glass plate 12 after heating. After the temperature cools to room temperature, record the height of the pellets 5 through the longitudinal scale line 14 of the glass plate 12.
[0030] Option 2: Press the resin powder into pellets 5 of the same specification. Record the initial diameter and thickness of the pellets 5 using a measuring tool.
