The invention relates to the technical field of
plastic packaging bag tensile detection, and discloses a
plastic packaging bag tensile detection device which comprises a
processing platform, a storage cabinet is arranged in the
processing platform, supporting legs are fixedly connected to the four corners of the bottom of the
processing platform, and a tensile detection mechanism is arranged at the top of the processing platform; the four corners of a
plastic bag are stably clamped through a screw rod, a movable clamping plate and a fixed clamping plate, cooperative movement of a motor sliding rail, a
linear motor, a movable frame, a sliding rod and a first sliding block is matched, pulling force on the two sides is converted into pulling force in four directions through an inclined sliding groove and a second sliding block, and stretching resistance detection in the four directions is conducted on the
plastic bag. According to the design, the limitation that only two-side stretching detection is adopted in the prior art is overcome, the tensile data of the
plastic bag in different directions can be obtained, the tensile performance of the plastic bag can be comprehensively evaluated, a more accurate basis is provided for quality evaluation, it is ensured that the plastic bags with different purposes can bear the tensile force in the corresponding direction in
actual use, and the detection precision is improved.
