Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a dual-cylinder synchronously rotating aggregate abrasion testing machine. Background Technology

[0002] Abrasion testing machine is an industrial testing device suitable for testing the abrasion resistance of materials such as rubber, tires, conveyor belts, shoe soles, and soft synthetic leather. Under a specified contact pressure and on a given area, it measures the amount of abrasion caused by the friction of the sample on a certain level of abrasive parts. Abrasion is the mass loss value of the sample, and the volumetric abrasion is calculated from the density of the sample. Then, the data is collected, compared, and analyzed to obtain the test results.

[0003] Chinese Utility Model Patent Publication No. CN210513986U discloses a paint abrasion resistance testing machine. The specification of this machine reveals that by setting a fixing ring and a clamping nut, the fixing ring and clamping nut cooperate to keep the paint sample compacted throughout the test, preventing slippage with the sample tray and improving measurement accuracy. Furthermore, by setting a left half, a right half, a fixing magnet, and an electromagnet, the cooperation of the fixing magnet and electromagnet facilitates the separation or closure of the left and right halves, making it easier to open and close the fixing ring and further facilitating the installation of the paint sample. The rubber pad and anti-slip texture are useful; the rubber pad allows the retaining ring to press the paint sample more tightly, and the anti-slip texture increases the static friction between the rubber pad and the paint sample, preventing the paint sample from slipping on the test tray during the test and improving the accuracy of the measurement. However, this paint abrasion resistance tester does not have a detachable sample tray, making it inconvenient to perform abrasion tests on samples of different sizes. In addition, this paint abrasion resistance tester only has a single set of abrasion components, which cannot perform different tests on various abrasion media and accessories, nor can it perform repeated tests on a single material. The test data is not accurate enough, and its practicality is poor. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a material abrasion testing machine with synchronous rotation of two cylinders, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a dual-cylinder synchronously rotating aggregate abrasion testing machine, including a base, a geared motor fixedly installed inside the base, a turntable fixedly installed on the output shaft of the geared motor, a protrusion fixedly installed at the center of the end of the turntable away from the geared motor, a stud fixedly installed at the center of the end of the protrusion away from the turntable, a sample tray provided on the side of the turntable away from the geared motor, a groove provided on the end of the sample tray near the turntable, a fixed seat fixedly installed on the top of the base away from the sample tray, a support arm provided on the inner side of the fixed seat, a fixed block fixedly installed on the side of the support arm away from the fixed seat, a connecting block fixedly installed on the top of the fixed block away from the sample tray, an air intake provided on the top of the fixed block, and a dust collection component rotatably installed on the outer surface of the connecting block.

[0007] The above technical solution improves the overall stability of the equipment by symmetrically installing four sets of support feet at the bottom of the base. The control panel allows operators to easily adjust the rotation speed of the sample tray. The support arm is rotatably connected to the fixed base via a rotating shaft, allowing for angle adjustment of the support arm and precise alignment of the grinding wheel with the sample tray. The fixed bracket with the grinding wheel threaded connection on the outside of the connecting column enables quick installation of the grinding wheel and facilitates its disassembly, allowing for the replacement of grinding wheels of different specifications according to experimental requirements.

[0008] Preferably, the groove and the protrusion are adapted to each other, the groove and the protrusion are snap-fit ​​connected, and the stud is connected through the sample tray.

[0009] Through the above technical solution, the matching of grooves and protrusions enables rapid positioning and installation of the sample tray and turntable. At the same time, the snap-fit ​​connection between the grooves and protrusions enables precise transmission between the turntable and sample tray, reducing wear and tear and extending their service life. Furthermore, the matching of grooves and protrusions facilitates quick disassembly of the turntable and sample tray, allowing staff to easily replace sample trays of different sizes according to the wear materials of different dimensions.

[0011] The above technical solution, by setting up a dust collection component, facilitates the collection of waste materials during abrasion tests, preventing dust from spreading outside the equipment or accumulating on the sample surface.

[0012] Preferably, the vent is connected to the suction port, the first suction port and the second suction port have the same structure, the first suction port and the second suction port are symmetrically distributed on the center line of the sample tray, and the inner diameter of the suction nozzle increases from the inside to the outside.

[0013] The above technical solution ensures waste collection by connecting the air inlet and the air outlet. By setting the first and second dust inlets to have the same structure and symmetrically distributed on the surface of the sample tray, the dust collection efficiency is improved. By setting the inner diameter of the dust nozzle to increase from the inside to the outside, the dust collection area can be effectively increased, thereby improving the waste collection efficiency.

[0014] Preferably, the outer surface of the sample tray is provided with a retaining ring, and an adjusting bolt is provided on the outer side of the retaining ring. The side of the sample tray away from the turntable is provided with a pressure plate that is slidably connected to the stud and a locking block that is threadedly connected to the stud.

[0015] The above technical solution involves first placing the sample to be tested on top of the sample tray, then installing the retaining ring on the outside of the sample tray, adjusting the tightness between the retaining ring and the sample tray by adjusting the bolts, and then pressing the pressure plate through the stud onto the surface of the sample. With the locking block and the threaded connection of the stud, the sample can be quickly fixed, preventing the sample from loosening during the wear process and ensuring the accuracy of the test data.

[0016] Preferably, there are two identical sets of sample trays and dust collection components. The two sets of sample trays and dust collection components are symmetrically distributed on the top of the base, and the two sets of sample trays correspond one-to-one with the two sets of dust collection components.

[0017] By using the above technical solution, and by setting up two sets of identical sample trays and dust collection components, it is possible to conduct different tests on various abrasive media and accessories, and also to perform repeated tests on the same point of a material.
