Description

Technical Field

[0001] The utility model relates to the technical field of powder industry, in particular to an amplitude adjustment device for testing the tap density of powder. Background Art

[0002] In the powder industry, tap density testing is a key indicator for evaluating powder material performance. Currently, common tap density test amplitudes include 3mm, 14mm, and 18mm. Currently, the vibration height of the vibration table and sample tube is altered by adding spacers. The test requires the use of different spacer types based on the operator's actual usage.

[0003] The method of adding pads in the prior art requires manual adjustment of the height and position of the pads to ensure the accuracy of the amplitude. This not only increases the complexity of the operation, but may also cause human errors and affect the accuracy of the test results. Every time the amplitude is changed, the pads need to be readjusted, which increases the time cost of test preparation. In test scenarios where the amplitude needs to be changed frequently, this method is particularly inefficient. Since the accuracy and stability of the pad adjustment are difficult to guarantee, the consistency of the amplitude may be affected during each test, resulting in poor repeatability of the test results. The method of adding pads may cause wear and damage to equipment components (such as pads, support structures, etc.), increasing the maintenance cost of the equipment. Utility Model Content

[0004] The purpose of the utility model is to provide an amplitude adjustment device for testing the tap density of powder, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0006] An amplitude adjustment device for testing the tap density of powder, comprising a measuring cylinder, a guide sleeve, a rotating motor, a lifting motor, a rotating motor bracket, a cam and a fixed sleeve connecting rod;

[0007] The rotating motor is fixed to the upper end of the lifting motor through a rotating motor bracket;

[0008] The cam is in a spiral curve shape and is provided with a center hole, and the center hole of the cam is mounted on the rotating motor;

[0009] The fixed sleeve connecting rod is connected to the measuring cylinder, and the fixed sleeve connecting rod is inserted into the guide sleeve;

[0010] The guide sleeve is connected to the equipment via a fixing plate;

[0011] The cam converts the rotational motion into an up-and-down motion of amplitude. The rotary motor rotates and drives the cam. When the cam rotates one circle from the highest point to the lowest point, it generates a free-fall vibration waveform for the measuring cylinder driven by the fixed sleeve connecting rod. The control system collects data for analysis and processing to obtain the tap density value of the powder.

[0012] The amplitude adjustment device for testing the tap density of powder, in a preferred embodiment, is that the measuring cylinder is a 100ml glass measuring cylinder, and scale lines are provided on the surface of the measuring cylinder.

[0013] A preferred embodiment of the amplitude adjustment device for testing the tap density of powder is that the cam is made of stainless steel.

[0014] A preferred embodiment of the amplitude adjustment device for testing the tap density of powder is that the lifting motor drives the amplitude adjustment device to move up and down according to a preset amplitude value.

[0015] The amplitude adjustment device for testing the tap density of powder is preferably applicable to powder testing equipment of various heights, can meet the diverse requirements for amplitude in different testing scenarios, and can realize the setting and switching of different test parameters through programming control.

[0016] The working principle of an amplitude adjustment device for testing the tap density of powders is as follows: a measuring cylinder is filled with sample and fixed to a fixed sleeve connecting rod; a lifting motor drives the amplitude adjustment mechanism up and down according to a preset amplitude value, achieving precise adjustment of the measuring cylinder's amplitude. After the rotary motor is started, a cam converts the rotary motion into an up and down movement of the amplitude, generating a stable vibration waveform. During the vibration process, the powder material moves randomly within the measuring cylinder, gradually packing tightly until a stable tap density is reached. The control system collects test data in real time, including amplitude, vibration frequency, and vibration time, and automatically analyzes and processes it to determine the tap density of the powder.

[0017] Beneficial effects

[0018] The utility model utilizes the precise control capability of the lifting motor and combines it with the cam mechanism driven by the rotating motor to achieve continuous and precise adjustment of the amplitude, thus ensuring the stability and consistency of the amplitude during the test.

[0019] Through automated control, this utility model can quickly respond to test requirements and reduce the time required for manual amplitude adjustment, thereby improving test efficiency. At the same time, precise amplitude control helps to improve the accuracy of test results and provide more reliable data support for the performance evaluation of powder materials.

[0020] The device is flexible in design and suitable for a variety of powder testing equipment, meeting the diverse amplitude requirements in different testing scenarios. Furthermore, through programming control, different test parameters can be easily set and switched, improving the adaptability and flexibility of the device.

[0021] Compared to traditional methods, this new method reduces equipment maintenance requirements and costs due to pad wear and improper adjustment. Furthermore, automated control simplifies operation, making it easy for non-professionals to use and improving testing convenience. This not only addresses the technical challenges of existing powder tap density testing but also provides new insights for further innovation in powder testing technology. By introducing advanced automated control technology, it is expected to drive the upgrading and development of the entire powder testing industry. BRIEF DESCRIPTION OF THE DRAWINGS
