Description

Cooling device for artificial board strength performance detection sample and clamping head Technical Field The utility model belongs to the technical field of artificial board detection, and particularly relates to a cooling device for an artificial board strength performance detection sample and a clamping head. Background The strength performance of the rough board is detected in the production process of the medium-density board or the shaving board so as to timely adjust the production process according to the strength performance of the rough board, and prevent the finished product after subsequent sanding from generating large-scale product defects. Therefore, it is important to improve the efficiency of measuring the strength performance of the blank and to ensure the accuracy of the measurement. The blank in the production process is cooled to room temperature after being cut, and then is measured according to the detection method of the internal bonding strength and static bending strength of national standards. And the internal bonding strength performance measurement is to uniformly coat the melted hot melt adhesive on the surface of the clamping head and bond the test piece and the clamping head together. In the actual measurement process, the clamping head needs to be heated to be more than 90 ℃ when the plate is adhered to the clamping head. The adhesive in the plate can be degraded in the high-temperature environment, so that the strength performance of the plate is reduced. In order to improve the efficiency of measuring the strength performance of the blank and to make the measurement result as accurate as possible, the process of combining and measuring the bonding chuck of the plate needs to obviously and stably reduce the temperature of the bonded plate and the chuck to the room temperature, and meanwhile, the supercooling of the plate is avoided, so that cold and hot impact is caused. The static bending strength is also required to be cooled to room temperature rapidly before measurement, and the external environment is ensured not to generate supercooling impact on the plate. Two methods are generally adopted at present, one is placed at a ventilation place for natural cooling, and the disadvantage is that the cooling speed is low, and the strength performance of the plate can be obviously reduced under the condition of long-time high-temperature baking of the plate. Secondly, put into the refrigerator with sticking chuck and the panel that awaits measuring, the advantage is that cooling rate is fast, but because external temperature is too low, can make the panel experience violent cold and hot impact at the cooling in-process, can reduce the intensity performance of panel, because in low temperature environment, easily make chuck and blank appear the drop of water because of the temperature difference condensation moreover, panel absorbs water influences intensity. To sum up, at present, a cooling device which is convenient and effective is lacking for cooling a blank and a clamping head which is stuck with the internal combination property to be detected.
