[0001] The present invention relates to the technical field of test chambers, and particularly to a high and low temperature test chamber for cloth-based tapes. Background Art

[0002] A cloth-based tape is a high-adhesion tape with a relatively large adhesive force, mainly used for carton sealing, carpet splicing, heavy bundling, waterproof packaging, etc. The cloth-based tape is based on the thermal compound of polyethylene and gauze fibers, coated with a high-viscosity synthetic glue, and has strong peel force, tensile strength, oil resistance, aging resistance, temperature resistance, waterproofness, corrosion resistance and other characteristics.

[0003] In many industrial and daily life application scenarios, the performance of cloth-based tapes is crucial. And in different temperature environments, the performance such as viscosity and elasticity of cloth-based tapes may change significantly. Some existing test equipment has many inconveniences when conducting high and low temperature tests on cloth-based tapes. For example, the fixation of cloth-based tapes is not convenient and stable enough, it is difficult to accurately detect the change in the tensile force of the tape during the test, and the operation is complex when switching between high and low temperature environments, etc., which cannot well meet the comprehensive and accurate performance test requirements of cloth-based tapes.

[0022] 3. The cooler can cool the refrigeration chamber, so that the base glue can be tested at low temperature. By starting the electric push rod, the driving plate can be driven to move. The driving plate can drive the rack seat to move. The rack seat can drive the rotating gear and the rotating shaft to rotate. The rotating shaft can drive the baffle to rotate. The rotation of multiple baffles can close the ventilation holes.

[0023] 4. By starting the drive motor, the drive motor can drive the drive shaft to rotate. With the cooperation of the drive bevel gear and the driven bevel gear, the drive shaft can drive the two threaded rods to rotate. The threaded rods can drive the lifting seat to move upward.
