AI Technical Summary

Problems solved by technology

Manual on duty, regular sampling is required, discontinuous after the test, and personnel are required to be on the test site, and the temperature after sampling is greatly affected, and the work efficiency is low; semi-automatic type, purely mechanized operation, needs to manually send the tray into the test box, and does not need to be tested during the test Continuous, you need to set the interval time, and exit a certain sample after the time is up, the test result is not continuous

Embodiment 1

[0055] For the tray 125 is a plate tray without holes, the operation steps and working principle of this embodiment:

[0056] 1. Turn on the main power supply, set the heating temperature T in the button setting area 16, the time required for sample feeding t2, the time for sample starting to discharge t3, the time required for sample discharge t4, the speed of the stepper motor for sample feeding N1, the sample Discharge stepper motor speed N2, blower motor speed P;

[0057] 2. Place the sample 20 on the tray 125, press the automatic test button in the button setting area 16, the controller 5 sends an instruction, the system automatically starts the blower motor 6, the heating ring 8 switch, the temperature in the box 1 rises, the temperature The sensor 10 monitors the temperature. After the heating temperature T is stabilized, the controller 5 issues an instruction, and the system automatically starts the stepping motor 7 to rotate counterclockwise. The speed of the stepping...

Embodiment 2

[0071] For the tray 125 is a frame tray with holes, the operation steps and working principle of this embodiment:

[0072] 1. Turn on the main power supply, set the heating temperature T in the button setting area 16, the time required for sample feeding t2, the time for sample starting to discharge t3, the time required for sample discharging t4, the time for continuing to output the sample tray t5, and the time for sample feeding Stepping motor speed N1, sample discharge stepping motor speed N2, sample tray continues to output stepping motor speed N3, blower motor speed P;

[0073] 2. Place the sample 20 on the sample tray, fix the sample tray on the tray 125 with adhesive tape, press the automatic test key in the button setting area 16, the controller 5 sends an instruction, and the system automatically starts the blower motor 6 and the heating ring 8 Switch, the temperature in the box 1 rises, and the temperature sensor 10 monitors the temperature. After the heating temper...

Embodiment 3

[0085] The automatic static heat resistance tester of the present application has a memory function. When the last operation of embodiment 3 was embodiment 1, the operation steps and working principle of the present embodiment:

Abstract

The invention discloses an automatic static heat resistance tester, which includes a support module, a control module and a control panel; the control module includes a controller, a blower motor, a stepping motor, a heating ring and a timer, and the blower motor and the heating ring are arranged on On the side wall of the box, the stepper motor is set on the bracket, the controller controls the blower motor, heating coil, temperature sensor and stepper motor, the stepper motor controls the feeding device, and the blower motor controls the turbofan; the control panel includes a temperature display area, button setting area, time display area, the temperature sensor tests the temperature of the sample; the button setting area is connected with the control module. The invention is equipped with automatic feeding and automatic discharging functions, the temperature in the box is stable, the airflow guide frame guides the airflow direction, and the airflow in the box is stable and uniform, so that the test results are continuous, convenient for comparison testing, and the accuracy is higher.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to an automatic static heat resistance tester. Background technique [0002] During the processing or reprocessing of plastic materials, they will be processed in extruders or internal mixers, and the temperature will be processed at 120-180°C or higher. The base material of plastic materials is generally resin, and high temperature will make them Decomposition or other problems lead to color changes of colored products (such as PVC modified materials, when all materials are mixed and stirred at high temperature, the surface temperature is usually around 120°C, and the internal temperature will be above 180°C, before entering the next process In the past, the powder in the front stage may be stored for a long time due to accidental factors such as color matching and incomplete extrusion in the back stage, which will cause the material to remain in a static high temperature...
