[0022] Please refer to Figures 1-5 , and make a further description of the embodiments of the present utility model;

[0023] A fineness gauge for a squeegee, comprising a measuring table 1, a fineness gauge scale plate 2 and a squeegee seat 3. A slot matching the fineness gauge scale plate 2 is opened on the upper surface of the measuring table 1, and the fineness gauge scale plate 2 is fitted into the slot of the measuring table 1. The squeegee seat 3 is oppositely arranged at the upper end of the measuring table 1;

[0024] Connectors 7 are fixed on both sides of the squeegee seat 3. Tooth rail grooves 6 are opened on both sides of the measuring table 1, and side rail seats 5 are slidably arranged outside the tooth rail grooves 6. An angle steel piece 9 is fixed between the side rail seats 5 and the connectors 7;

[0025] A squeegee 4 is arranged at one end of the squeegee seat 3 close to the fineness gauge scale plate 2. A curved arm 13 is movably arranged between the squeegee 4 and the squeegee seat 3, and a push shaft 11 runs through the curved arm 13. An air pump group 8 is fixed on the squeegee seat 3, and the air pump group 8 is movably docked with the push shaft 11;

[0026] For this fineness gauge for a squeegee, the fineness gauge scale plate 2 fitted and fixed to the measuring table 1 can be replaced with fineness gauge scale plates 2 of different precision specifications according to actual measurement precision requirements. After placing the material to be measured at one end of the fineness gauge scale plate 2 during measurement, the horizontal position of the squeegee seat 3 is adjusted along the tooth rail groove 6 mainly by pushing the squeegee seat 3. During this period, the air pump group 8 and the push shaft 11 longitudinally push the curved arm 13 to press the squeegee 4 according to the position angle of the curved arm 13. Through the horizontal displacement of the squeegee 4 on the fineness gauge scale plate 2 and by pushing and spreading the material to be measured during this period, the squeegee measurement is completed;

[0027] Compared with the traditional manual measurement method, this fineness gauge for a squeegee strictly maintains the horizontal displacement positions of the squeegee seat 3 and the squeegee 4 on the fineness gauge scale plate 2 through the sliding fit structure of the squeegee seat 3, the side rail seats 5 and the tooth rail grooves 6 to ensure the displacement precision of the entire horizontal pushing displacement. At the same time, the air pressure pushing force continuously supplied by the air pump group 8 and the push shaft 11 is used to ensure the force stability of the entire squeegee scraping the material to be measured, that is, the consistency of the measurement action direction and the applied force during the entire measurement process is controlled, the reliability of the measurement data of this fineness gauge for a squeegee is improved, the manual measurement method is simplified at the same time, and the measurement data differences caused by the measurement method when dealing with materials to be measured with poor ductility are avoided.

[0028] Furthermore, a corner wheel 10 is hingedly arranged on one side of the squeegee seat 3 close to the squeegee 4, and the corner wheel 10 is fixedly connected to the curved arm 13, and the turning amplitude of the corner wheel 10 matches that of the curved arm 13. The external corner wheel 10 and the curved arm 13 are hingedly and movably matched to conveniently adjust the angle of the corner wheel 10 according to the damping provided by the structural connection end. Furthermore, the included angle size formed by the squeegee 4 and the surface of the fineness gauge scale plate 2 is adjusted by adjusting the angle of the corner wheel 10, improving the adjustability of this fineness gauge for a squeegee.

[0029] Further, the air pump group 8 is an inflatable air pump shaft controlled by the on-off of an air valve, and the shaft port end of the air pump group 8 is matched with the piston of the push shaft 11. The inflatable air pump group 8 controlled by the on-off of the air valve is used to conveniently adjust the actual thrust of the push shaft 11 through the inflation pressure data, improving the adjustability of the blade fineness gauge.

[0030] Further, a gear 15 and a wheel bearing 17 are rotatably arranged in the side rail seat 5 in an axial docking manner. A striped tooth groove matching the gear 15 is grooved in the tooth rail groove 6, and the gear 15 is in rolling fit with the tooth rail groove 6. Further, the gear 15 and the tooth rail groove 6 with tooth pattern fit are used to provide relative sliding accuracy for the sliding structure of the side rail seat 5 and the measuring table 1 to meet the actual measurement requirements.

[0031] Further, a motor group 14 is arranged on one side of the gear 15 in the side rail seat 5, and a transmission chain 16 is arranged between the motor group 14 and the wheel bearing 17. By braking the motor group 14 of the electric type, the gear 15 is driven to follow along the wheel bearing 17 by the transmission of the transmission chain 16. Furthermore, the manual pushing measurement is replaced by the automatic rolling of the switch gear 15 in the tooth rail groove 6, simplifying the measurement operation.

[0032] Further, the air pump group 8 is externally connected with a solenoid valve port pipe controlled by air pressure. The air source pipeline can be connected through an external supply method, and the solenoid valve port pipe is controlled by on-off through real-time air pressure monitoring to challenge the push pressure in the air pump group 8, improving the adjustability of the blade fineness gauge.
