[0002] Low-compression kneaded silicone rubber is a special type of silicone rubber with low compression set (compression set). This means that after compression, the material quickly returns to its original shape, maintaining excellent elasticity and stability. It is typically used in applications where high compression set is required, ensuring long-term performance. Modification of low-compression kneaded silicone rubber involves adding various fillers, additives, or employing specialized processing techniques to enhance its performance and adaptability to various applications. Modification can improve its physical properties, chemical stability, temperature resistance, mechanical strength, and aging resistance, among other properties, to meet the requirements of specific industries.

[0003] In the prior art, a modification device is required to modify the silicone rubber before mixing it. At this time, suitable fillers and modifiers need to be added and heated and mixed according to the application performance requirements of the silicone rubber. However, the existing modification device does not have the function of quantitative feeding of fillers and modifiers. Generally, they need to be weighed and quantified in advance and then added to the interior of the modification device. This operation is time-consuming and labor-intensive, which greatly reduces the processing efficiency of the silicone rubber. To this end, we propose a modification device for producing low-compression mixed silicone rubber and a modification method thereof to solve the above problems. Summary of the Invention

S5: Finally, after the rubber material, liquid modifier, filler or solid modifier are added in sequence, the heating rod is energized to heat the rubber material, liquid modifier, filler or solid modifier, and then the motor is started to drive the stirring shaft, multiple stirring rods and two scrapers to rotate. At this time, the rubber material, liquid modifier, filler or solid modifier can be efficiently stirred and mixed, and the modification effect of the silicone rubber can be accurately controlled by controlling the heating temperature.

[0022] The beneficial effects of the present invention are: 1. Open the sealing cover and add the liquid modifier that needs to be adjusted into the interior of the metering cylinder. At this time, the addition amount of the liquid modifier can be accurately set through the metering cylinder.

At the same time, when the second motor rotates, it can also drive the disc to rotate. At this time, the disc can drive the bottom end of the push rod to rotate and move up and down on the disc. At this time, the push rod can drive the knocking rod and the impact block to move up and down, thereby vibrating the feed pipe through the cooperation between the impact block and the feed pipe. Here, the vibration of the feed pipe can promote the discharge of solid materials, prevent sticking to the wall, and ensure the smooth discharge of materials. 4. By starting the third motor, the screw rod can be driven to rotate. At this time, the threaded connection between the screw rod and the moving rod can drive the moving rod to move horizontally. At this time, the moving rod can drive the baffle plate to move horizontally. When the baffle plate moves to the left, the internal channel of the feed pipe can be blocked to facilitate the quantitative addition of fillers and solid modifiers. When the baffle plate moves to the right, the internal channel of the feed pipe can be opened to facilitate the discharge of rubber, fillers and solid modifiers. The present invention realizes rapid quantitative feeding during the modification processing of low-compression mixed silicone rubber through a simple structure, can ensure the precise ratio between the rubber material, filler and modifier, and does not require personnel to quantify in advance through weighing equipment, which saves time and labor and is highly practical.
