Description

Technical Field

[0001] This utility model relates to the field of food-grade silicone rubber product testing technology, specifically to an online detection device for the coloring degree of food-grade silicone rubber products. Background Technology

[0002] In the food processing, packaging, and storage sectors, silicone rubber is widely used in food contact components such as food sealing gaskets, nipples, and baking molds due to its excellent flexibility, temperature resistance, and chemical stability. However, as the food industry's requirements for product quality and safety continue to increase, traditional silicone rubber is prone to discoloration during food contact, severely affecting the appearance and quality of food, and potentially posing a threat to food safety.

[0003] Therefore, after the silicone rubber is processed, it is necessary to test its anti-coloring performance. The test items include mechanical properties, temperature resistance, chemical corrosion resistance, and migration test. After the test, the coloring degree of the test piece is further tested again to obtain the final test result. The traditional method of coloring degree testing is to use a colorimeter. During the testing process, the staff also need to manually flip the silicone rubber sheet, which greatly affects the testing efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide an online detection device for the coloring degree of food-grade silicone rubber products. The device can flip and adjust the silicone rubber parts to achieve rapid detection on both sides of the product, which greatly improves the detection efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an online detection device for the coloring degree of food-grade silicone rubber products, comprising a frame, a detection chamber fixedly connected to the upper end of the frame, a colorimeter installed in the detection chamber, a control panel cooperating with the colorimeter on the detection chamber, a lifting cylinder fixedly connected to the frame, the colorimeter fixedly connected to the lower end of the lifting cylinder, a detection platform slidably connected to the frame, a feeding window cooperating with the detection platform at one end of the detection chamber, a moving mechanism for driving the detection platform to slide on the frame; a first detection seat fixedly connected to the detection platform, a bracket fixedly connected to one side of the first detection seat on the detection platform, a second detection seat hinged in the bracket, a flipping mechanism for driving the second detection seat to flip on the bracket; a movable groove on the upper surface of the second detection seat, a pneumatic adsorption platform slidably inserted into the movable groove, a pneumatic adsorption mechanism on the pneumatic adsorption platform, and a spring fixedly connected between the pneumatic adsorption platform and the movable groove.

[0006] As an improvement, the pneumatic adsorption mechanism includes an air cavity located inside the pneumatic adsorption platform, an adsorption hole communicating with the air cavity is provided at the upper end of the pneumatic adsorption platform, and a vacuum pump is fixedly connected to the bottom surface of the pneumatic adsorption platform.

[0007] As an improvement, the moving mechanism includes a moving block fixedly connected to the bottom surface of the testing table, a moving groove that cooperates with the moving block on the frame, a screw rotatably connected in the moving groove, the moving block being threadedly connected to the outer wall of the screw, and a motor that drives the screw to rotate being fixedly connected to one end of the frame.

[0008] As an improvement, the flipping mechanism includes a gear rotatably connected to one side of the bracket to drive the second detection seat to rotate, an electric push rod is fixedly connected to the detection platform, and a rack that meshes with the gear is fixedly connected to one end of the electric push rod.

[0009] As an improvement, a buffer pad that mates with the second detection seat is fixedly connected to the end of the detection platform away from the first detection seat.

[0010] The advantages of this invention compared to the prior art are as follows: the silicone rubber part to be tested is placed on the upper end of the first testing seat, and the testing platform is driven into the testing chamber for testing by the moving mechanism. After the testing is completed, the flipping mechanism is activated to drive the second testing platform to flip 180 degrees, so that the pneumatic adsorption platform adsorbs the silicone rubber part. Then, the flipping mechanism is activated to start the second testing platform to flip in the opposite direction and reset, so that the other side of the silicone rubber part can be tested, which greatly improves the testing efficiency.
