Description

Technical Field

[0001] The utility model is applicable to the technical field of adhesive tape manufacturing, and particularly relates to an electric heating device safety device for an adhesive tape. Background Art

[0002] At present, latex tape is in a molten state before it is dried. When a factory manufactures latex, it needs to conduct a large number of experiments on latex tape to test the quality and effect of the latex coated on the surface of the tape. In the experiment, the plastic tape coated with latex will be placed in an electric heating box for heating and drying to form it, and then its quality will be tested.

[0003] However, nowadays, when placing the latex-coated plastic tape inside the electric heating box for heating and drying, the tape sample to be tested is often placed flat inside the corresponding test plate, and then the test plate and the tape sample are pushed and placed inside the electric heating box simultaneously. After the heating and drying process, the operator needs to take out the test plate from the electric heating box and test the dried tape sample. When the electric heating box is heated up, the temperature of the internal space of the electric heating box will also rise synchronously, which will cause the operator to take out the test plate. Once the operator makes an error in operation and reaches into the electric heating box without wearing the corresponding heat-insulating gloves, it is very easy to come into direct contact with the box with higher air temperature and get injured, which will affect the subsequent detection efficiency. Therefore, we propose a safety device for electric heating devices of tapes. Utility Model Content

A sliding roller is rotatably sleeved on the outer surface of each fixing rod, and the top of the sliding roller is movably fitted to the outer bottom surface of the containing frame.

[0011] By adopting the above technical solution, the rotation of the sliding roller can provide the necessary assistance for the movement of the containing frame, thereby increasing the moving speed of the containing frame.
