[0003] Existing testing procedures for hot-melt foam include appearance inspection, viscosity test, and curing time test. These testing methods all rely on visual observation to determine the test results, which may lead to inaccurate test results and low accuracy. Utility Model Content

[0004] The purpose of the utility model is to provide a foam hot melt detection mechanism to solve the problem that the detection result may be inaccurate and the accuracy of the detection result is low.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: a foam hot melt detection mechanism, including a detection platform, a heat insulation cover is fixed on the top surface of the detection platform, a heater is provided on the top surface of the heat insulation cover, two support columns are fixed on the top surface of the detection platform, a fixing plate is provided above the detection platform, both sides of the bottom surface of the fixing plate are respectively fixed to the top ends of the two support columns, a sliding hole is opened on the top surface of the fixing plate, a sliding rod is slidably inserted into the inside of the sliding hole, a pressing plate is fixed to the bottom end of the sliding rod, and a counterweight column is fixed to the top end of the sliding rod.

[0011] Compared with the existing technology, a foam hot melt detection mechanism using the above technical solution has the following features:

[0012] Beneficial effects:

[0013] 1. The staff will first place the foam on the top surface of the test table, and then the heater in the working state will cause the space between the test table and the insulation cover to heat up, so that the foam on the test table is in a high-temperature environment for hot melt testing. During the hot melt testing process, the pressing plate will press on the top surface of the foam, and use the sliding rod and the gravity of the counterweight column to apply a downward force to the foam. When the foam melts due to the high temperature environment, the pressing plate will sink into the inside of the foam, and then drive the sliding rod to slide downward inside the sliding hole. At this time, the temperature inside the insulation cover will be detected by the temperature sensor, and then the temperature sensor will send the specific temperature value to the PLC controller, and then the PLC controller will send the specific temperature value to the display, which will make it easy for the staff to understand the current temperature value inside the insulation cover, and can detect the quality and performance of the foam. The change in the sliding distance of the sliding rod inside the sliding hole is used to judge the test result of the foam, thereby increasing the accuracy of the test result;

[0014] Second, before placing the foam on the top surface of the test bench, the staff will first apply forces in opposite directions to the two sliding plates, causing the two sliding plates to move away from each other and compress the extrusion springs. Then, the staff will place the foam between the two sliding plates and withdraw the forces applied to the sliding plates. At this time, the two compressed extrusion springs push the two sliding plates closer together and clamp the foam to the test bench, increasing the firmness of the foam's position on the test bench.

[0015] 3. The staff can observe the progress of the current foam hot melt test through the transparent plate made of ultra-white glass. During the hot melt test, the flip plate is vertically placed on the test table. At this time, the bottom of the flip plate is inside the limit groove, and the reset spring is in an uncompressed state. By pushing up the blocking column, the bottom of the flip plate can be fixed inside the limit groove to prevent heat loss inside the insulation cover and increase the sealing between the test table and the insulation cover.
