Description

Technical Field

[0001] The invention relates to the technical field of softness testers, in particular to a softness tester. Background Art

[0002] As China's consumer market matures, the softness of paper has become a key indicator for measuring the quality of products. There are many methods and instruments for testing softness internationally. Domestically, a cutter-type softness tester is usually used. The softness of paper is characterized by recording the pressure applied by the cutter when the paper sheet is deformed to a specified degree. Therefore, there are high requirements for the sensitivity and accuracy of the cutter sensor.

[0003] When using it, a calibration device is used, and the current calibration device is generally composed of Figure 5 As shown, the cutting head and the weights are connected to the bottom of both sides of the beam through calibration lines. However, the above technical solution has certain defects when used. For example, it is well known that when one side of the balance is too heavy, the beam on the balance will suddenly tilt at a large angle. If the hand does not retract in time after placing the weights or the cutting head, the sudden tilt of the beam may cause harm to the user. In addition, the beam in the above technical solution cannot be quickly returned to its original position, which may waste a certain amount of calibration time. Summary of the invention

[0008] Preferably, both sides of the crossbeam are provided with sliding grooves, the interior of the sliding grooves is slidably connected with a counterweight block, the top of the crossbeam is provided with a threaded hole, the interior of the threaded hole is threadedly connected with a fixing bolt, and the bottom of the fixing bolt is in conflict with the counterweight block.

[0009] Preferably, the mounting mechanism includes a mounting base fixedly mounted on the softness tester body, the connecting column is located inside the mounting base, through holes are provided on both sides of the mounting base, a second electric telescopic rod is fixedly mounted inside the through hole, and a clamp is fixedly connected to the piston end of the second electric telescopic rod.

[0010] Preferably, a hook-shaped connector is provided at the bottom of the calibration line, and the cutter head and the weight are connected to the calibration line via the hook-shaped connector.

[0011] The beneficial effects of the present invention are as follows: a softness tester provided by the present invention, when in use, connects the connecting column to the mounting mechanism, and the lever structure composed of the crossbeam and the connecting column can transmit the pulling force generated by the weight to the sensor of the softness tester body connected to the cutter head, thereby achieving the effect of accurate calibration. Before calibration, the cutter head and the weight need to be connected to two sets of calibration lines respectively to prevent the crossbeam from tilting suddenly when the cutter head or the weight is placed. The first electric telescopic rod can be started to push the limit block upward so that the push block collides with the crossbeam. If one side is too heavy, the crossbeam will squeeze the push block to move downward so that the crossbeam will not tilt suddenly and cause harm to the user. The calibration result can be judged by observing the spirit level. If the crossbeam needs to return to its original position quickly, the first electric telescopic rod can be started to push the limit block upward. When the push block collides with the crossbeam, the limit block continues to be pushed upward so that the limit block collides with the crossbeam, thereby quickly returning the crossbeam to its original position, saving adjustment time before calibration.
