Description

Technical Field

[0001] This utility model relates to the field of tablecloth testing technology, and more specifically, to a tensile testing device for processing plastic tablecloths. Background Technology

[0002] Tablecloths, also known as "tablecloths," are primarily used to prevent dirt from seeping into tables. They are everyday items that protect against dust and stains, and are generally made of materials such as plastic and polyester fabric. During the processing of plastic tablecloths, their tensile strength needs to be tested, requiring a strength testing device. For example, the tensile strength testing device for plastic tablecloth processing disclosed in patent CN216208160U involves winding the plastic tablecloth onto a winding roller, then rotating an adjusting screw. The adjusting screw causes the upper and lower clamping blocks to move towards each other, and the upper and lower clamping blocks move a locking block into a through groove, securing one end of the plastic tablecloth. The movable clamping mechanism can hold the other end of the plastic tablecloth in place, ensuring that the plastic tablecloth is fixed during testing and improving the accuracy of the test. The second motor drives the second threaded rod to rotate, and the second threaded rod then drives the movable seat to move horizontally, thereby moving the movable clamping mechanism to achieve the purpose of tensile testing on the plastic tablecloth. The plastic tablecloth is stretched during the test, and the test results can be displayed intuitively through the scale lines. The first motor drives the first threaded rod to rotate, and the first threaded rod then drives the movable plate to move vertically downward, and the movable plate then drives the guide rod to move downward.

[0003] When the above device is in use, the adjusting screw drives the upper clamping block and the lower clamping block to move towards each other. The upper clamping block and the lower clamping block drive the fitting block to be inserted into the through groove, which clamps one end of the plastic tablecloth. The moving clamping mechanism can clamp the other end of the plastic tablecloth, ensuring that the plastic tablecloth is fixed during the test. However, the tablecloth needs to be passed through the outer end face of the winding roller and wrapped half a turn. Due to the obstruction of the upper clamping block, the installation of the tablecloth is relatively inconvenient. At the same time, when clamping the tablecloth, the through groove also needs to be rotated to align with the fitting block. Utility Model Content
