Description

Technical Field

[0001] The utility model relates to the technical field of rubber material testing, in particular to a sealing rubber sealing performance testing device. Background Art

[0002] Existing sealant manufacturers must test the sealing performance of sealants under certain load-bearing conditions before the sealants leave the factory to ensure that they meet the factory standards. The existing testing method is generally to first use the sealant to be tested to bond the glass pot body and the bottom of the pot separated from each other, and after the sealant is completely dry, fix the pot body and then hang a weight at the bottom of the pot. After hanging for a period of time, observe whether the bottom of the pot will fall off the pot body and whether the bonding part will come apart. Add water to the glass pot and observe whether the bonding part will leak to determine the sealing performance of the sealant.

[0003] After searching, the Chinese patent application number CN213239346U discloses a sealant sealing test device, including: a bracket; a limiting mechanism, which is arranged on the bracket to limit the pot body and keep the bottom of the pot and the bonding part away from the air; a crimping mechanism, the lower end of which can extend into the pot body and abut against the bottom of the pot, and a weight is placed on the upper limit of the crimping mechanism; and a protective mechanism, which can prevent the crimping mechanism from moving downward.

[0004] A sealant sealing test device in the above patent has the following shortcomings: in the above patent, the sealant performance is tested by the cooperation between the weight and the pressure rod, but the weight test method has a long test time and relatively low test efficiency, which affects the detection efficiency of the test device.

[0011] With the above structure, the two synchronous wheels can be rotated synchronously through the cooperation between the synchronous wheel and the synchronous belt.

[0012] The output shaft of the servo motor is fixedly connected to one of the synchronous wheels, and one end of the transmission shafts of the two synchronous wheels is fixedly connected to the two screw rods respectively.

[0013] With the above structure, the screw is driven to rotate by the rotation of the synchronous wheel.

[0014] The test assembly is located directly above the test pot, and the cross-section of the driving column is an external T-shaped structure.

[0015] By adopting the above structure, the bottom of the test pot is squeezed by the test component, thereby facilitating the testing of the performance of the sealant.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model facilitates the testing of the sealant performance by using a test pot through the cooperation between the detection component and the test component. The cooperation between the pressure sensor and the detection seat in the test component facilitates the detection of the pressure of the detection seat on the bottom of the test pot.

[0018] (2) The utility model provides two screws in the detection tube, and cooperates with a servo motor, a synchronous belt and a synchronous wheel to directly drive the screws to rotate, thereby driving the driving column to adjust its pressure on the bottom of the pot.
