[0033] The horizontal pressure plate 5, the edge of the horizontal pressure plate 5 is fixed with a sealing ring 6, the sealing ring 6 is symmetrically distributed above and below the center of the horizontal pressure plate 5, the outer edge of the sealing ring 6 is tightly fitted with the inner surface of the pressure plate limiting groove 4, the above structure design can avoid the leakage of the sealant from the edge of the horizontal pressure plate 5, and ensure the accuracy of the test, the top surface of the horizontal pressure plate 5 is fixed with a threaded connecting rod 7, the threaded connecting rod 7 penetrates a stable hole 8, the stable hole 8 is opened on a stable frame 9, the stable frame 9 is fixedly installed at the top of the cylindrical cavity 1, a limiting column 10 is installed on the top surface of the stable frame 9, the top end of the limiting column 10 is fitted with the bottom surface of a blocking plate 11, the blocking plate 11 is fixedly installed on the threaded connecting rod 7, and a weight 12 is installed on the top of the threaded connecting rod 7;

[0034] The cylindrical cavity 1, a support threaded rod 13 is fixedly installed on the bottom surface of the outer wall of the cylindrical cavity 1, the support threaded rod 13 is connected with the inner wall of a support sleeve 14, and the support sleeve 14 is fixedly installed with an anti-skid pad 15 on the bottom of the outer wall.

[0035] In one embodiment, the center of the threaded connecting rod 7, the stable hole 8 and the cylindrical cavity 1 are on the same vertical line, the threaded connecting rod 7 and the stable hole 8 are in sliding connection, and the above structure design enables the horizontal pressure plate 5 to move stably and linearly along the stable hole 8 when moving vertically, with the threaded connecting rod 7 being centered.

[0036] In one preferred embodiment, the limiting columns 10 are symmetrically distributed about the center of the blocking plate 11, and the distance between the symmetric limiting columns 10 is greater than half the length of the front view of the blocking plate 11, the above structure design enables the limiting columns 10 to stably support the downward moving blocking plate 11, the threaded connecting rod 7 and the weight 12, and improves the blocking and limiting effect of the horizontal pressure plate 5 in cooperation with the pressure plate limiting groove 4.

The above structural design allows for easy adjustment of the number of weights 12 installed according to the consistency of the material during testing, and also facilitates the installation and removal of the weights 12.

[0038] In one preferred embodiment, the support threaded rod 13 and the support sleeve 14 are threadedly connected. Both the support threaded rod 13 and the support sleeve 14 are symmetrically distributed about the center of the cylindrical cavity 1.

The valve on the extrusion pipe 3 is closed, and the valve on the material inlet pipe 2 and the valve on the sampling port pipe of the automatic production equipment are opened. The sealant enters the cylindrical cavity 1 through the material inlet pipe 2 from the sampling port pipe of the automatic production equipment, and pushes the horizontal pressure plate 5 upward. The horizontal pressure plate 5, with the sealing ring 6, slides upward along the pressure plate limiting groove 4. The threaded connecting rod 7 installed on the top of the horizontal pressure plate 5 also slides upward steadily along the stabilizing hole 8.

[0041] Once the amount of sealant added is sufficient, close the valve on the material inlet pipe 2 and the valve on the sampling port pipe of the automatic production equipment. Based on the consistency of the sealant being tested, select an appropriate number of weights 12 and rotate the weights 12 to the top of the threaded connecting rod 7. Then open the material inlet pipe 2. Under the gravity of the weights 12, the horizontal pressure plate 5 slides down along the pressure plate limiting groove 4 to squeeze the sealant. The sealant is squeezed out from the extrusion pipe 3. Record the amount of sealant squeezed out per unit time.
