Description

Technical Field

[0001] This utility model relates to the field of ceramicized silicone rubber technology, and in particular to a heat resistance testing device for the production of ceramicized silicone rubber. Background Technology

[0002] Ceramicized silicone rubber is a polymer composite material that can be transformed into ceramic materials at high temperatures, and is mainly used in the manufacture of fire-resistant wires and cables. After the rubber is produced, heat resistance testing is required. The heat resistance test simulates a high-temperature environment to observe whether the material will deform, soften, or decompose.

[0003] Operators typically use an acetylene torch to heat the rubber surface. The flame temperature of an acetylene torch can reach over 1,000 degrees Celsius. Compared to liquefied petroleum gas (LPG) torches, acetylene torches have the advantages of higher temperature and faster heating. However, using an acetylene torch does pose certain risks, primarily including explosion and backfire. Strict adherence to safety regulations is essential; therefore, it remains dangerous for operators to hold an acetylene torch while heating rubber. Utility Model Content

[0004] The purpose of this application is to provide a heat resistance testing device for the production of ceramicized silicone rubber, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A heat resistance testing device for the production of ceramicized silicone rubber includes two mounting plates and an experimental assembly mounted on the two mounting plates. A metal mesh is fixedly installed between the two mounting plates. The experimental assembly includes a cutting blade, a rotating rod, and two flame nozzles. The two flame nozzles are movably mounted above the metal mesh. The cutting blade is movably mounted above the metal mesh, and each end of the cutting blade is equipped with a cylinder. The cylinders are fixedly mounted on the outer side wall of the mounting plate. The rotating rod is rotatably mounted at the end of the metal mesh. The cutting blade is positioned between the flame nozzles and the rotating rod. A second motor is fixedly installed on one outer side wall of the mounting plate, and the rotating rod is driven by the second motor. A through slot is formed on one end of the outer wall of each of the two mounting plates, and one end of the rotating rod is embedded in the slot.

[0007] Preferably, a bidirectional screw is provided above the metal mesh, with its two ends connected to the outer walls of two mounting plates via bearings. A motor is fixedly installed on the outer wall of each mounting plate, driving the bidirectional screw. Two sliders are symmetrically threaded onto the outer side of the bidirectional screw, and the two flame nozzles are fixedly connected to the two sliders respectively. A guide rod is provided below the metal mesh, with its two ends fixedly connected to the two mounting plates. Two industrial cameras are symmetrically mounted on the outer side of the guide rod. Connecting rods are symmetrically arranged on both sides of the metal mesh, and the connecting rods are fixedly installed between the sliders on the bidirectional screw and the industrial cameras.

[0008] The beneficial effects of this utility model are: by setting up experimental components, the rubber sheet can be heated automatically, and the flame nozzle can be moved to adapt to rubber sheets of different sizes, eliminating the need for manual operation by operators and improving safety.

[0015] like Figure 1-4The device shown is a heat resistance testing apparatus for the production of ceramicized silicone rubber. It includes two mounting plates 1 and an experimental assembly mounted on the two mounting plates 1. A metal mesh 2 is fixedly installed between the two mounting plates 1. The experimental assembly includes a cutting blade 8, a rotating rod 10, and two flame nozzles 5. The two flame nozzles 5 are movably mounted above the metal mesh 2. The cutting blade 8 is movably mounted above the metal mesh 2, and each end of the cutting blade 8 is equipped with a cylinder 7. The cylinders 7 are fixedly mounted on the outer side wall of the mounting plate 1. The rotating rod 10 is rotatably mounted at the end of the metal mesh 2. The cutting blade 8 is positioned between the flame nozzles 5 and the rotating rod 10. A second motor 9 is fixedly mounted on one outer side wall of the mounting plate 1, and the rotating rod 10 is driven by the second motor 9. A slot 11 is formed through one end of the outer wall of each of the two mounting plates 1, and one end of the rotating rod 10 is embedded inside the slot 11.

[0016] A bidirectional screw 3 is positioned above the metal mesh 2. Both ends of the bidirectional screw 3 are connected to the outer walls of two mounting plates 1 via bearings. A motor 6 is fixedly mounted on the outer wall of the mounting plates 1, driving the bidirectional screw 3. Two sliders are symmetrically threaded onto the outside of the bidirectional screw 3, and two flame nozzles 5 are fixedly connected to the two sliders respectively. A guide rod 12 is positioned below the metal mesh 2. Both ends of the guide rod 12 are fixedly connected to the two mounting plates 1. Two industrial cameras 13 are symmetrically mounted on the outside of the guide rod 12. Connecting rods 4 are symmetrically positioned on both sides of the metal mesh 2, and the connecting rods 4 are fixedly mounted between the sliders on the bidirectional screw 3 and the industrial cameras 13.

[0017] Example: Two mounting plates 1 are installed between two belt conveyors. The plate-shaped ceramicized silicone rubber is transported by the belt conveyors and transported to the top of the metal mesh 2. Two flame nozzles 5 are connected to external fuel tank pipes. When started, they will spray high-temperature flames to heat the rubber plate. After the motor 6 starts, it can drive the bidirectional screw 3 to rotate. After rotation, the slider on the bidirectional screw 3 drives the flame nozzles 5 to move. At the same time, the slider drives the industrial camera 13 to move on the guide rod 12 through the connecting rod 4. Because it is necessary to test the heat resistance of rubber plates of different specifications and sizes, it is necessary to adjust the detection position of the flame nozzles 5 and the industrial camera 13. As the surface of the rubber plate is continuously heated, ceramicization will occur on the surface of the rubber plate. The industrial camera 13 at the bottom of the metal mesh 2 will capture the heating position of the rubber plate. If the rubber plate has insufficient heat resistance due to processing problems, the rubber plate may crack or even burn through. The industrial camera 13 needs to record the image simultaneously, and the operator at the control end will observe it. After the heat resistance test is completed, the belt conveyor is started, which carries the rubber sheet a certain distance. The heated part of the rubber sheet is transported to the bottom of the cutting blade 8. The cylinder 7 drives the cutting blade 8 to move down and press against the surface of the rubber sheet. Since the burning part has become ceramicized and hard, the motor 9 needs to be started to drive the rotating rod 10 to flip. The rotating rod 10 drives the end of the rubber sheet to flip upward. The rotating rod 10 folds the rubber sheet and cooperates with the cutting blade 8, so that the rubber sheet breaks from the burning part. At this time, the operator can observe the fracture point of the rubber sheet and record the internal condition of the ceramicized rubber sheet.
