Description

Technical Field

[0001] The utility model relates to the technical field of cable testing, in particular to a process testing machine for low-smoke, halogen-free and flame-retardant cable materials. Background Art

[0002] In the field of cable material process testing machines, traditional testing machines often have many shortcomings when testing low-smoke halogen-free flame-retardant cable materials. Traditional methods mainly use simple melt index tests and oxygen index tests to evaluate the flame retardant properties of cable materials, but these methods cannot fully reflect the actual performance of low-smoke halogen-free flame-retardant cable materials, resulting in inaccurate evaluation results. In addition, traditional testing machines produce a large amount of harmful gases during the test process, which pollutes the environment and poses safety hazards.

[0003] A Chinese patent with announcement number CN213239755U discloses a low-smoke halogen-free flame-retardant cable material process testing machine, which includes a bottom frame, a front surface wall of the bottom frame is fixedly mounted with a controller, and a fixing plate is fixed to the top of the bottom frame, the upper surface wall of the fixing plate is symmetrically connected with vertical poles, the top of the vertical pole is connected with a first mounting plate, a hydraulic cylinder is mounted at the middle position of the top of the first mounting plate, and the bottom end of the hydraulic cylinder is connected to a guide plate through a telescopic rod. The patent adds a clamping assembly consisting of a screw, a clamping plate and a first support block at the front and rear ends of the fixing plate respectively, and the clamping plate is moved downward by rotating the screw to thereby press against the cable material placed on the first support block. Two sets of clamping assemblies can be used to clamp the two ends of the cable material respectively, so that the cable material is fixed stably and firmly, avoiding the defect that the cable is easy to rotate and improving the accuracy of the test.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] The existing device moves the test head downward to contact and squeeze the cable. The infrared distance sensor on the test head can detect the distance between the upper limit block and the second support block, thereby monitoring the cable deformation. However, the cable will face high temperature, wear and tear during actual use, so corresponding tests are required for the high temperature resistance and wear resistance of the cable. The existing device can only detect the cable deformation, which has limitations in actual use. Utility Model Content

The temperature indicator arranged inside the heating box can display data. The motor drives the rotating rod to rotate, so that the first grinding wheel and the second grinding wheel can be rotated, and the cable fixed between the first grinding wheel and the second grinding wheel is polished, thereby achieving the test effect of the cable wear resistance.
