[0031] An oil seepage structure consisting of a rubber cover 11, a grease bin 12, and a smear ball 19 is provided above the carrier 1. After injecting test grease into the grease bin 12, the outlet size is adjusted by sliding the rubber cover 11 to control the flow rate. The grease is evenly spread on the parchment surface using the smear ball 19, forming a standardized test interface for oil seepage testing.

[0032] The platform 1 is provided with a pair of guide slots 2, which account for four-fifths of the total length of the platform 1.

The first screw 6 is threadedly connected to the grease bin 12 to accurately control the movement path. The rubber cover 11 adjusts the outlet cross-sectional area by sliding, and cooperates with the oil-seeping micropore design of the smearing ball 19 to achieve precise control of the amount of grease applied, and the amount of grease adhesion per unit area can be adjusted for parchment papers with different oil-seeping properties.

[0035] Working principle: When using the parchment oil permeability detection device, first fix the test paper flatly on the upper surface of the detection support plate 4 through the magnetic block 18, and the second servo motor 15 drives the second screw 10 and the third screw 14 to rotate, driving the horizontal axis bracket 8 to rise and fall, forming an XYZ three-axis linkage with the lateral movement of the first screw 6, driving the grease bin 12 to move, and the test grease in the grease bin 12 is adjusted by the rubber cover 11 to control the outlet cross-sectional area and control the flow rate, and then seeps out from the oil seepage pores of the smearing ball 19 and is evenly smeared on the parchment surface; at the same time, the industrial cameras 9 distributed at both ends of the horizontal axis bracket 8 scan and collect images at any position on the parchment surface without dead angles; the control host 3 has a built-in power module and control module to realize one-button start of the entire "smearing-detection" process and coordinated control of each servo motor, and finally the oil permeability of the parchment is judged by analyzing the image transmitted by the industrial camera 9.
