Description

Technical Field

[0001] The utility model relates to the technical field of tap density measurement, in particular to a detection device and a tap density system. Background Art

[0002] Tap density refers to the mass per unit volume of powder in a container measured after tapping under specified conditions. Figure 1 As shown, the tap density measurement method is as follows: weighed powder is placed into the measuring cylinder 01 of the tapping device, which is fixed to the support 02. The cam 03 is rotated, and the directional rod 04, guided by the guide sleeve 05, drives the support 02 to slide vertically. The support 02 strikes the anvil 06, compacting the powder. After the cam 03 stops rotating, the volume of the powder in the measuring cylinder 01 is measured. The ratio of the powder mass to the volume is the tap density of the powder. The tapping device vibrates 250 times per minute, each vibration lasting 12 minutes, with an amplitude of 3 mm.

[0003] However, the vibration amplitude of the graduated cylinder 01 gradually decreases as the cam 03 wears, causing the measured tap density to decrease. Since the vibration amplitude of the graduated cylinder 01 cannot be monitored, it is impossible to accurately determine whether the measurement results of the tap density device are accurate.

[0043] By using the monitoring part 21 to monitor whether the weighing piece 11 reaches the specified height during vibration to detect whether the amplitude of the weighing piece 11 reaches the set amplitude, it can be used to determine whether the compaction component 1 is worn, and then parts can be replaced in time to make the measurement results of the compaction component 1 more accurate.

[0044] like Figure 3 As shown, in one embodiment, the detection component 2 includes: a counting member 22, which is electrically connected to the monitoring member 21 and is used to count the number of times the weighing member 11 reaches a specified height during vibration. By monitoring the amplitude of the weighing member 11 in a counting manner, the detection result is more accurate, and it is possible to more accurately judge whether the structure of the vibration component 1 will affect the measurement result and whether it is necessary to replace parts. As a convertible embodiment, it is also possible to only set the monitoring member 21 to judge whether the weighing member 11 can reach a specified height during vibration, without judging the number of times the specified height is reached.

[0045] like Figure 2-Figure 3As shown, in one embodiment, the monitoring part 21 is an infrared sensing structure.

Furthermore, the counting member 22 is used to count the number of times the amplitude of the weighing member 11 reaches the maximum amplitude. Specifically, the setting height of the infrared ray transmitting port of the transmitting part 211 and the infrared ray receiving port of the receiving part 212 are the same as the height of the top of the weighing member 11 at the maximum amplitude.

As a convertible embodiment, it is also possible that the setting height of the monitoring member 21 is the same as the height of the weighing member 11 near the top, and there is no excessive restriction here.

[0047] like Figure 2 As shown, in one embodiment, the detection device includes: a sensing member 3 fixedly disposed at the top of a weighing member 11, and an infrared sensing structure inductively connected to the sensing member 3. The sensing member 3 is a light-transmitting structure. By providing the sensing member 3, an inductive connection with the infrared sensing structure can be achieved, thereby increasing the accuracy of the detection results and preventing the weighing member 11 from failing to accurately receive the infrared signal. As a variable embodiment, the sensing member 3 may also be omitted.

[0049] In one embodiment, the weighing member 11 is a measuring cylinder for weighing the volume of the powder. As a convertible embodiment, the weighing member 11 can also be a common cylinder or other containing structure, which is not limited here.

[0050] like Figure 2As shown, in one embodiment, the vibration assembly 1 includes: a support base 12, a weighing member 11 is fixed on the upper part of the support base 12; a sliding member 13 is fixedly arranged below the support base 12; a vibrating member 14 is arranged below the sliding member 13 and contacts the sliding member 13, and is used to drive the sliding member 13 to slide in the vertical direction. Among them, the vibrating member 14 is a cam, which is connected to the output end of the motor. The maximum amplitude of the vibration of the measuring cylinder driven by the cam is 3mm, and the vibration frequency is 250 times / min; the vertical direction is Figure 2 By providing the vibrating member 14, the weighing member 11 can be driven to move in the vertical direction, thereby compacting the powder in the accommodating cavity.

[0051] like Figure 2 As shown, in one embodiment, the compaction assembly 1 includes a guide member 15 having a hollow cavity, in which a sliding member 13 is inserted. The sliding member 13 is a sliding rod, and the guide member 15 is a bearing. The guide member 15 can guide the movement direction of the sliding member 13. As an alternative embodiment, the guide member 15 can be omitted, or pads can be provided on both sides of the sliding member 13.

[0052] The detection principle of the vibration compaction system in this embodiment is as follows:

[0053] Step 1: Fix the sensing element 3 to the top of the measuring cylinder, and fix the emitting portion 211 and the receiving portion 212 of the infrared sensing structure to opposite sides of the measuring cylinder, and set the infrared sensing structure at the same height as the top of the measuring cylinder at the maximum amplitude;

[0054] Step 2: Weigh a certain amount of powder into a measuring cylinder, and fix the measuring cylinder on the support base 12;

[0055] Step 3: Set the vibration time to 12 minutes, that is, set the vibration frequency to 3000 times. The motor drives the cam to rotate, which in turn drives the sliding rod, the support base 12, and the measuring cylinder to slide in the vertical direction. The bottom end of the support base 12 collides with the top end of the bearing, thereby compacting the powder in the measuring cylinder.

[0056] Step 4: The transmitting unit 211 transmits an infrared signal to the sensing element 3. The sensing element 3 sends the received infrared signal to the receiving unit 212, and the counting unit 22 performs counting.

[0057] Step 5: After stopping the vibration, read the reading of the counting member 22 and compare it with the set vibration number of 3000 times.
