Description

Technical Field

[0001] This invention relates to the field of abrasion testing machine technology, and specifically to an abrasion resistance testing device for building materials. Background Technology

[0002] After the building materials are manufactured, they need to be tested using an abrasion testing machine to ensure the quality and performance of unglazed tiles.

[0003] For example, Chinese patent CN221745788U describes a ceramic tile abrasion resistance testing machine, which includes a chassis. A grinding wheel is fixedly installed on the top surface of the chassis. A positioning fixture is fixedly connected to one side of the grinding wheel. A storage hopper is fixedly installed above the positioning fixture. A sand discharge pipe is fixedly connected below the storage hopper. A connector is fixedly connected to the bottom end of the sand discharge pipe. A sand discharge nozzle is fixedly connected below the connector. The storage hopper, sand discharge pipe, connector, and sand discharge nozzle are sequentially connected. A sand discharge assembly is provided on the inner wall of the sand discharge pipe. One end of the sand discharge assembly is provided with a sand discharge quantity adjustment assembly and a sand discharge direction adjustment assembly. By setting the sand discharge assembly and the sand discharge quantity adjustment assembly, the operator can adjust the gap between the two sand baffles by changing the angle of the second rotating rod, thereby changing the sand discharge quantity. This allows the operator to adjust the sand discharge quantity according to the usage requirements and guide the abrasive to the grinding wheel friction surface with a uniform thickness, improving the accuracy and precision of the test results.

[0004] However: the positioning fixture is fixedly connected to the counterweight, and the counterweight will continuously exert pressure on the positioning fixture in contact with the friction steel wheel. When installing building materials, the force of the counterweight must be overcome to ensure that there is a gap between the positioning fixture and the friction steel wheel for the installation of building materials, making the installation of building materials difficult. At the same time, the force of the positioning fixture in contact with the friction steel wheel cannot be adjusted as needed; in addition, the abrasive cannot be circulated and cannot be adapted to long-term testing.

[0005] Based on this, the present invention designs a wear resistance testing device for building materials to solve the above problems. Summary of the Invention

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The present invention will be further described below with reference to embodiments.

[0024] The lifting component of the follow-up clamping assembly 3 moves upward, pushing the adjustable counterweight assembly upward. The adjustable counterweight assembly does not exert force on the follow-up support assembly, which is in a movable state. Building materials can be installed onto the follow-up support assembly without overcoming the weight of the adjustable counterweight assembly, which is convenient for operators. At the same time, according to the pressure requirements of the building materials on the grinding end of the grinding assembly 6 during wear resistance testing, the adjusting component adjusts the weight of the adjustable counterweight assembly, so that the tension generated by the adjusted weight of the adjustable counterweight assembly ensures that the pressure requirements of the building materials on the grinding end of the grinding assembly 6 meet the testing requirements. This allows for corresponding adjustments as needed, improving adaptability. During testing, the circulating abrasive supply assembly 4 can collect the ground abrasive and re-feed it, realizing abrasive circulation supply. During testing, the dust removal assembly 5 collects the dust and gas generated during testing, preventing dust and gas from polluting the processing environment.

The horizontal shaft 336 drives the second bevel gear 324 to rotate. The second bevel gear 324 drives the first bevel gear 36 to rotate. The first bevel gear 36 drives the second threaded rod 313 to rotate. Under the guidance of the first guide rod 32, the second threaded rod 313 drives the return plate 37 to move upward. The return plate 37 of the lifting assembly pushes the lowest weight 33 of the adjustable counterweight assembly to move upward, and then pushes the other weights 33 to move upward. After all the weights 33 have moved upward, the steel cable 31 is in a slack state. The adjustable counterweight assembly does not exert tension on the base plate 322 of the follow-up support assembly. The base plate 322 of the follow-up support assembly is in a movable state. Then, the base plate 322 of the follow-up support assembly is slid, and the base plate 322 moves away from the grinding assembly 6 along the horizontal bar 320. Then, the handwheel 31 is turned. 7. Handwheel 317 drives threaded rod 318 to rotate. Under the guidance of column 315 and second guide rod 316, threaded rod 318 drives clamping plate 325 to move away from grinding component 6, placing building material on base plate 322. The building material is located between clamping plate 325 and grinding component 6. Turning handwheel 317 drives threaded rod 318 to rotate. Under the guidance of column 315 and second guide rod 316, threaded rod 318 drives clamping plate 325 to move towards grinding component 6. Clamping plate 325 pushes building material to contact the two sets of second guide rods 316 on the right, fixing the building material between clamping plate 325 and the two sets of second guide rods 316 on the right. The building material can be installed on the base plate 322 of the follow-up support component without overcoming the gravity of the adjustable counterweight component, which is beneficial for operators to install building materials.

[0030] Based on the pressure requirements of the building materials on the grinding end of the grinding component 6 during wear resistance testing, a set number of weights 33 are selected. The first cylinder 329 of the adjustment component drives the pressure plate 332 to move upward, and the first motor 38 drives the first threaded rod 310 to rotate. Under the guidance of the guide rail assembly 311, the first threaded rod 310 drives the side moving plate 338 to move along the guide rail assembly 311. The side moving plate 338 drives the pad 333 to move upward. The pad 333 moves until it contacts the bottom of the horizontal plate 35. Under the guidance of the third guide rod 331, the first cylinder 329 drives the pressure plate 332 to move downward, and the pressure plate 332 drives the second groove... The inner wall of 337 is in contact with the side wall of the horizontal plate 35, and the inner wall of the first groove 334 is in contact with the pressure plate 332. The pressure plate 332 and the pad 333 cooperate to clamp the horizontal plate 35. The second cylinder 330 drives the connecting frame 335 to move away from the weight 33. The connecting frame 335 drives the pressure plate 332 and the pad 333 to move away from the weight 33. The pressure plate 332 and the pad 333 drive the horizontal plate 35 to move away from the weight 33. The horizontal plate 35 drives the insertion rod 326 to move away from the weight 33. After the insertion rod 326 separates from the weight 33, the first motor 38 drives the first threaded rod 310 to rotate. Under the action of the rail assembly 311, the first threaded rod 310 drives the side moving plate 338 to move along the rail assembly 311. The side moving plate 338 drives the pad 333 and the pressure plate 332 to move. The pressure plate 332 and the pad 333 drive the horizontal plate 35 to move vertically. The horizontal plate 35 drives the insertion rod 326 to move vertically. When the insertion rod 326 moves to the lowest weight 33 among the selected number of weights 33, the first motor 38 stops rotating. The second cylinder 330 drives the horizontal plate 35 to move towards the lowest weight 33 among the selected weights 33. The horizontal plate 35 drives the insertion rod 326 to move towards the lowest weight 33 among the selected weights 33. When the rod 326 is inserted, it connects to the first insertion hole 39 of the bottommost weight 33 of the selected weights 33 and the second insertion hole 328 of the straight cylinder 327. The rod 326 connects the straight cylinder 327 and the selected weights 33 together as a selected counterweight. Under the action of the third guide rod 331, the first cylinder 329 drives the pressure plate 332 to move upward and separate from the horizontal plate 35. The second cylinder 330 drives the pad 333 to separate from the horizontal plate 35. The weight 33 below the bottommost weight 33 of the selected weights 33 is supported on the rectangular plate 37. The weight 33 below the bottommost weight 33 of the selected weights 33 does not participate in the counterweight.

[0031] The second motor 323 drives the horizontal shaft 336 to rotate, the horizontal shaft 336 drives the second bevel gear 324 to rotate, the second bevel gear 324 drives the first bevel gear 36 to rotate, the first bevel gear 36 drives the second threaded rod 313 to rotate, and under the guidance of the first guide rod 32, the second threaded rod 313 drives the return plate 37 to move downward, and the return plate 37 drives the weight 33 below the lowest layer of the selected weight 33 and the adjustment component to move downward.

[0032] The selected weights 33 and the straight cylinder 327 move downwards under their own weight without any support at the bottom, causing the steel rope 31 to taut. The steel rope 31 moves along the guide wheel 319, causing the base plate 322 to move along the crossbar 320. The base plate 322 moves the fixed building material towards the grinding assembly 6, ensuring that the building material is always in contact with the grinding end of the grinding assembly 6.
