Description

Technical Field

[0001] The invention relates to the technical field of vacuum cleaner equipment, in particular to a vacuum cleaner filter performance testing device. Background Art

[0002] The vacuum cleaner filter testing device is a key equipment for evaluating the performance of vacuum cleaner filters. It simulates the working state of the vacuum cleaner and performs a series of tests on the filter to ensure its filtration efficiency, durability and other indicators. The vacuum cleaner filter testing device is widely used in vacuum cleaner production, research and development, and quality inspection.

[0003] However, when performing performance tests on existing vacuum cleaner filters, the degree of automation in testing the vacuum cleaner filters is insufficient, and it is also not convenient to quickly visualize the filtering performance of the filter, which reduces the equipment's detection efficiency of the filter. Therefore, a vacuum cleaner filter performance testing device is needed to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a vacuum cleaner filter performance testing device 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: a vacuum cleaner filter performance test device, comprising a support base for support, wherein four corners of the upper end surface of the support base are provided with square pillars, a support top seat is fixedly provided on the upper end surface of the square pillar, and a limit slot is provided at the center of the upper end surface of the support top seat.

[0006] A guide cylinder, wherein the guide cylinder is fixedly arranged on the upper end surface of the support top seat through the limit slot, and a cylinder push rod is arranged at the output end of the lower end surface of the guide cylinder;

[0007] An air guide device, wherein the air guide device is slidably engaged with the inner end surface of the support top seat through the cylinder push rod;

The positioning slot 211 can provide a sufficient guiding basis for the high-pressure nozzle 32, thereby improving the accuracy of the subsequent positioning of the high-pressure nozzle 32 to the inside of the support guide seat 212, thereby improving the efficiency of subsequent detection of the vacuum cleaner filter 251.

[0044] Working principle: Before use, the staff can position the vacuum cleaner filter 251 loading robot arm to the front of the support top seat 7, so that the subsequent robot arm can quickly load and replace the vacuum cleaner filter 251, and then the air intake duct 31 can be connected with the external air guide duct, so as to facilitate the subsequent continuous introduction of different mixed air for testing. When the vacuum cleaner filter 251 is loaded, in the initial state, the threaded slide 255 and the support guide seat 212 are in a separated state, and then the robot arm can guide the vacuum cleaner filter 251 to the upper part of the filter fixture 259. At this time, the servo motor 24 is started, and the servo motor 24 can synchronously drive the two sets of guide screws 26 to rotate through the synchronous pulley 22 and the synchronous belt 23, so that the two sets of guide screws 26 can be connected with the threaded slide 255 through the thread, and then drive the threaded slide 255 to be closed inside the support guide seat 212, and then the guide cylinder 5 is started, and the guide cylinder 5 can drive the cylinder push Rod 4 moves downward, at this time, the cylinder push rod 4 can synchronously drive the alignment slide 34 to move downward, so that the alignment slide 34 can synchronously drive the three groups of high-pressure nozzles 32 to be positioned inside the positioning slot 211, and at the same time, the sealing ring 33 can perform a sealing operation on the upper part of the positioning slot 211, and then the external air guide pipe can introduce the mixed gas into the high-pressure nozzle 32, and the high-pressure nozzle 32 can introduce the gas into the threaded slide 255 through the positioning slot 211. At this time, the gas passes through the vacuum cleaner filter 251, and then the vacuum cleaner filter 251 can filter various dusts in the gas. At the same time, the high-speed gas can make the vacuum cleaner filter 251 generate thrust, thereby driving the filter fixture 259 to move downward, so that the spring retaining ring 258 elastically contracts, and at this time, the pressure sensor 257 can sense and detect the continuous thrust, so as to quickly and stably determine the continuous pass rate performance of the vacuum cleaner filter 251. When the thrust increases to a certain extent, the detection is terminated.
