[0030] A gauge spacer 25 is arranged between the two partitions 22 to maintain the gap between the two partitions 22. The essential technical effects and implementation process of the technical solution herein are as follows:

[0031] The workpiece 4 enters the gauge 2 from the track 1, and finally the qualified ones enter the material frame 3, and the unqualified ones are quickly ejected from the U-shaped groove for isolation;

[0032] The gauge spacer is selected according to the thickness of the corresponding product to ensure that the passed gasket product meets the deformation requirements, and the unqualified product is blocked and isolated.

[0033] The track 1 is a slope track with an inclination of 30-60°, which ensures that the product automatically slides smoothly to the gauge 2;
