[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0023] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the attached Figure 1 , and is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting this application.

[0024] like Figure 1-5 As shown, a UV stability tester for rubber filler oil products includes a test box 1, an ultraviolet lamp 2, a partition 3, and a door panel 13. The ultraviolet lamp 2 is set on the top of the test box 1, the front of the test box 1 is open, and the door panel 13 is hingedly set. The partition 3 is placed horizontally in the test box 1, and the edge is fixedly connected to the inner wall of the test box 1. Multiple rotating shafts 5 are rotatably connected to the partition 3, and the rotating shafts 5 are connected to a driving assembly for driving them to rotate. The top of the rotating shaft 5 is fixedly connected to a placing table 4, and the top of the placing table 4 is provided with a groove. A sample cup 10 is movably set in the groove of the placing table 4. A lifting structure is provided at the center of the multiple placing tables 4, and a stirring paddle 18 connected to the lifting structure is provided in each sample cup 10.

[0025] Specifically, by simultaneously driving the placement table 4 and the rotating shaft 5 to rotate, the stirring paddle 18 stirs the rubber filling oil product in the sample cup 10, thereby ensuring the test results.

[0026] Furthermore, the driving assembly includes a driven gear 6, a motor bracket 7, a motor 8, and a driving gear. The bottom end of each rotating shaft 5 is fixedly connected to a driven gear 6, and multiple rotating shafts 5 and driven gears 6 are distributed in a ring shape, and a driving gear is provided at the center. At the same time, the driving gear is engaged with multiple driven gears 6. The motor bracket 7 is fixedly connected to the bottom of the partition 3, the motor 8 is fixedly mounted on the motor bracket 7, and the output shaft of the motor 8 is connected to the driving gear for driving it to rotate.

[0027] Specifically, the driving gear in the center is driven to rotate by the motor 8, so that the driving gear synchronously drives the driven gear 6 to rotate, and then the rotating shaft 5 rotates accordingly.

[0028] Furthermore, the lifting structure includes a vertical sleeve 14, a column 15, a frame 16, and a connecting rod 17. The vertical sleeve 14 is located at the center of multiple placement platforms 4, and the vertical sleeve 14 is fixedly connected to the partition 3. The vertical sleeve 14 is a hollow structure, and the column 15 slides with the vertical sleeve 14. The top of the column 15 is fixedly connected to the frame 16, and the ends of the frame 16 are connected to the stirring paddle 18 through the connecting rod 17.

[0029] Specifically, the column 15 can slide and rise and fall in the vertical sleeve 14 to adjust the height, and is detachable, so that it can be avoided when the sample cup 10 is placed, and the stirring paddle 18 can be cleaned after being disassembled.

[0030] Furthermore, a positioning ear 12 is fixedly connected to the outer wall of the sample cup 10, and a positioning groove 11 adapted to the positioning ear 12 is provided on the groove wall of the placement table 4. When the sample cup 10 is placed in the placement table 4, the positioning ear 12 on the outer wall of the sample cup 10 is inserted into the positioning groove 11, so that the sample cup 10 will not rotate in the placement table 4, thereby preventing self-rotation.

[0031] Furthermore, the placement tables 4 and the rotating shafts 5 are arranged in groups of three or four so as to be able to test multiple groups of rubber extension oil products at the same time.

[0032] Furthermore, the horizontal cross-sections of the vertical sleeve 14 and the vertical column 15 are rectangular to prevent the vertical sleeve 14 and the vertical column 15 from rotating.

[0033] Furthermore, the rotating shaft 5 is rotationally connected to the partition 3 via a bearing to ensure the stability of the rotation of the rotating shaft 5.

[0034] In the above structure, the rubber filler oil product to be tested is placed in the sample cup 10, and the column 15, the frame 16 and the connecting rod 17 are pulled to raise and avoid it. Then, the sample cup 10 is placed in the placement table 4, and the column 15 is loosened, so that the stirring paddle 18 falls into the sample cup 10 and contacts the rubber filler oil product. The door panel 13 is closed, the ultraviolet lamp 2 is turned on, and then the motor 8 is started to drive the driving gear to rotate. The driving gear engages and drives the driven gear 6 to rotate, thereby rotating the rotating shaft 5 and the placement table 4, so that the stirring paddle 18 stirs the rubber filler oil product in the sample cup 10, so that the ultraviolet lamp 2 evenly irradiates the rubber filler oil product.

[0035] The above shows and describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application.
