The bottom end of the first clamping mechanism is fixedly provided with a sliding block through a tension sensor, the top end of the base is provided with a linear driving mechanism for driving the sliding block to move back and forth between the two second clamping mechanisms, and by arranging the first clamping mechanism and the two second clamping mechanisms, two to-be-tested oxford fabric samples can be fixed at the same time during testing; after the pulling test on one side is finished, the second sample can be directly tested in the resetting process of the first clamping mechanism, so that the waiting time is shortened, and the working efficiency is improved.

Description

Technical Field

[0001] The utility model relates to the technical field of Oxford cloth production, in particular to an Oxford cloth tearing strength testing device. Background Art

[0002] Oxford cloth is also called Oxford spinning. It is mostly made of polyester cotton blended yarn interwoven with cotton yarn, and adopts square weave with heavy weft. It is easy to wash and dry, soft to the touch, good moisture absorption, and comfortable to wear. It looks like yarn-dyed cloth. It was named because the earliest student uniform shirts of Oxford University used this cotton cloth. Oxford cloth is treated with a waterproof agent during post-processing to make the surface of the fabric waterproof. After processing, the Oxford cloth with waterproof properties is not only waterproof, but also has the advantages of sun protection and UV protection, which is convenient for outdoor use.

[0003] When Oxford cloth is produced, its samples need to be tested for tear strength to ensure product quality. Existing Oxford cloth tear strength testing devices generally clamp and position the two ends of the Oxford cloth through a clamping mechanism, and then pull one end of the Oxford cloth for testing. In actual use, only a single Oxford cloth can be tested, and the driving mechanism needs to repeatedly drive the clamping mechanism at one end to move forward and backward, resulting in low work efficiency. Summary of the invention

[0004] The utility model aims to provide an Oxford cloth tearing strength testing device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an Oxford cloth tear strength testing device, comprising a base, two second clamping mechanisms respectively arranged at both ends of the base in the length direction, and a first clamping mechanism arranged between the two second clamping mechanisms, a slider being fixed to the bottom end of the first clamping mechanism through a tension sensor, and a linear driving mechanism for driving the slider to move back and forth between the two second clamping mechanisms being arranged at the top end of the base.

[0006] Furthermore, the first clamping mechanism includes a first bottom plate, a first fixed top plate and a first movable plate which are arranged in parallel vertically and horizontally between the first bottom plate and the first fixed top plate and are movable vertically by a first lifting member. The first bottom plate and the first movable plate are used to simultaneously fix one end of two pieces of Oxford cloth.

[0007] Furthermore, the four corners of the first bottom plate and the first fixed top plate are connected by vertical guide rods, and the first movable plate is slidably connected to the guide rods.

[0008] Furthermore, support plates are vertically fixed on both sides of the top of the base along its length direction, and the second clamping mechanism includes two second bottom plates and a second top plate horizontally fixed at the upper and lower ends of the support plate close to the first clamping mechanism, and a second movable plate is provided between the second bottom plate and the second top plate to move up and down through a second lifting member.

[0009] Furthermore, the first bottom plate and the first movable plate, and the second bottom plate and the second movable plate are provided with mutually matching positioning protrusions and positioning grooves on the opposite sides.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] By arranging a first clamping mechanism and two second clamping mechanisms at the top of the base, two Oxford cloth samples to be tested can be fixed at the same time during the test. After the pulling test on one side is completed, the second sample can be directly tested during the resetting of the first clamping mechanism, thereby reducing waiting time and improving work efficiency.

[0012] By providing the positioning protrusion and the positioning groove, the clamping stability can be improved, and the Oxford cloth can be prevented from being separated from the first clamping mechanism or the second clamping mechanism during the pulling process, resulting in failure in testing.
