Specific embodiment
As shown in Figure 1,3, a kind of plastics physicochemical property detection device includes heating box 1, and clamping component 2 is located in heating box
On 1 wall, tensioning component 3 includes sliding rail 31, and stepper motor 32 is located on sliding rail 31, and stepper motor 32 passes through connecting rod
33 connect with front end fixing clamp 34；
Described 31 one end of sliding rail is located in heating box 1, the other end is located at outside heating box 1；
Infrared heating device 4 is set in the heating box 1.
Preferably, temperature inductor 5(is set in the heating box 1 in use, temperature inductor 5 is closer to add object to be measured
Body surface face, test data are more quasi-), temperature inductor 5 is connect by controller 6 with infrared heating device 4, warm when work
The temperature in the actual measurement heating box 1 of inductor 5 is spent, the temperature data that controller 6 is surveyed according to temperature inductor 5 controls temperature sense
The working condition of device 5 is answered, if temperature is lower than observed temperature, start-up temperature inductor 5 works, on the contrary then stop temperature
The work of inductor 5 reduces the temperature in heating box 1 by methods such as forced ventilations.
Preferably, sliding rail 31 is equipped with multiple displacement sensors 7, the displacement sensor 7 respectively with control
Device 6 processed connects, every to pass through a displacement sensor 7 when stepper motor 32 moves on sliding rail 31, will start correspondence
Displacement sensor 7, controller 6 can correspond to starting and receive 7 signal of displacement sensor, and controller 6 is according to the position of different location
Move the signal of inductor 7, it can judge 33 shift length of stepper motor.
In Fig. 2,1 surface of heating box is equipped with peep hole 8, and peep hole 8 is equipped with heat-protecting glass, and high-speed camera 9 is located at
Outside heating box and it is directed at peep hole 8, in test, making high-speed camera 9(camera is per minute according to 360) alignment sight
Hole 8 is examined, and film recording is carried out to the overall process of test and can establish by the ex-post analysis of the photo to high-speed camera 9
It tests to the complete image as stretching, with development test to as critical limit deformation values.
Working principle: it takes with a collection of plastic processing into a plurality of shape, the identical threaded plastic item of size, and will wherein one
One end of plastic strip is fixed on clamping component 2, the other end is fixed on front end fixing clamp 34, later start-up temperature inductor 5
Heating box 1 is heated, reaches the temperature in heating box 1 and presets requirement, but maintain the temperature for a period of time, then
Starting stepper motor 32 drives plastic strip to be stretched, and carries out corresponding observation and obtain at such a temperature, under some value of thrust
Stretching data, gradually heating can be carried out to same plastic strip and is tested, different plastic strips can also be carried out different
The test of temperature.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as limitation of the invention, this hair
