The interior of the fixed block 4 is a hollow structure, and a sliding block 5 adapted to the fixed block 4 is slidably installed on the mounting frame 3. The sliding block 5 is slidably embedded in the fixed block 4, and the fixed block 4 and the sliding block 5 cooperate with each other and support the rubber strip to be polished. The bottom surface of the mounting frame 3 is installed with an electric push rod Ⅰ6, and the push rod of the electric push rod Ⅰ6 is connected to the sliding block 5. A driving wheel 7 is rotatably installed at the end of the moving block 5, and a waterproof motor 8 is also installed at the end of the sliding block 5. The output shaft of the waterproof motor 8 is connected to the rotating shaft of the driving wheel 7. A driven wheel 9 is rotatably installed at the end of the fixed block 4. A motor 10 is installed in the middle of the top surface of the frame 1, and a grinding wheel 11 is connected to the output shaft of the motor 10. The grinding wheel 11 is used for the rubber strip on the mounting frame 3. The rubber sleeve on the mounting frame 3 is continuously driven by the chain conveyor 2 to move to the grinding wheel 11 for grinding, thereby improving the grinding efficiency of the rubber strip; the mounting frame 3 is composed of a bracket and a disc, and the disc of the mounting frame 3 is radially opened with a slide groove, the sliding block 5 and the fixed block 4 are symmetrically distributed in the slide groove of the disc of the mounting frame 3, and the sliding block 5 is radially stretched from the fixed block 4 to elastically clamp the rubber strip.

[0022] like Figure 4 As shown, a cooling member is provided on the frame 1, and the cooling member includes a water tank 12 and a driving member. The water tank 12 is installed on one side of the top of the frame 1, and the frame 1 is provided with a driving member for driving the water tank 12 to rise and submerge the rubber strip on the mounting frame 3 by driving the water tank 12 to rise and make the water therein immerse the rubber strip on the mounting frame 3, so that the water tank 12 wets and cools the rubber strip before grinding through the water inside it, thereby improving the grinding effect of the rubber strip; the driving member includes a guide rod 13 and an electric push rod II 14, and a plurality of guide rods 13 are provided on the top of the frame 1, and the water tank 12 is slidably installed on the guide rods 13. An electric push rod II 14 is also installed on the top of the frame 1, and the push rod of the electric push rod II 14 is connected to the water tank 12, and the electric push rod II 14 can drive the water tank 12 to rise and fall under the guidance of the guide rod 13, so that the water inside the water tank 12 can wet and cool the rubber strip on the mounting frame 3 moving above it.

[0023] like Figure 1 and Figure 4As shown, a collecting frame 15 is installed at the bottom of one end of the frame 1 away from the water tank 12, and the collecting frame 15 is used to collect the polished rubber strips in a centralized manner; a collecting rod 16 is installed inside the collecting frame 15, and the top of the collecting rod 16 is lower than the top surface of the frame 1. The collecting rod 16 is used to connect and stack the rubber strips that are released to the collecting frame 15 after being polished on the mounting frame 3, and the collecting rod 16 is conducive to concentrating the polished rubber strips.

[0024] When the rubber strip is polished, first place the polished rubber strip on the periphery of the fixed block 4 and the sliding block 5 on the mounting frame 3, and then activate the chain plate conveyor 2. When the chain plate conveyor 2 drives the mounting frame 3 to move, the electric push rod Ⅰ6 is activated, and the electric push rod Ⅰ6 drives the sliding block 5 to slide in the slide groove of the mounting frame 3 through the push rod. After the sliding block 5 slides out from the fixed block 4, the fixed block 4 and the sliding block 5 will jointly stretch the rubber strip placed on the outside thereof, so that the rubber strip is elastically stretched and then limited on the mounting frame 3. When the rubber strip on the mounting frame 3 moves to the top of the water tank 12, The chain conveyor 2 stops driving the mounting frame 3, and the electric push rod II 14 is activated at this time. The electric push rod II 14 will push the water tank 12 upward through the push rod, so that the water tank 12 is lifted to the position of the mounting frame 3 just above it under the guidance of the guide rod 13. The water in the water tank 12 will soak on the rubber strip supported by the fixed block 4 and the sliding block 5. After the water in the water tank 12 soaks and cools the rubber strip for a certain period of time, the electric push rod II 14 drives the water tank 12 to move downward, and after the rubber strip is separated from the water, it continues to drive the mounting frame 3 to rotate through the chain conveyor 2. When the mounting frame 3 drives the rubber strip thereon to move When the chain conveyor 2 moves to the grinding wheel 11, the chain conveyor 2 is suspended. At this time, the waterproof motor 8 and the motor 10 are started synchronously. The waterproof motor 8 will be enabled to rotate the output shaft drive wheel 7. The rotating drive wheel 7 will cooperate with the driven wheel 9 to rotate the rubber strip on it. At this time, the motor 10 will also drive the grinding wheel 11 to rotate, so that the rubber strip on the mounting frame 3 can be rotated and polished synchronously, so that the rubber strip can be polished evenly all around, and when the chain conveyor 2 is suspended, the rubber strip on the mounting frame 3 following the adjacent grinding wheel 11 will be soaked in the raised water tank 12 synchronously, thereby When the conveyor 2 intermittently drives the mounting frame 3 to rotate, each time the previous rubber strip is being polished, the subsequent rubber strip can be soaked and cooled at the same time. When the polished rubber strip on the mounting frame 3 is transported to the top of the collecting frame 15 by the chain conveyor 2, the electric push rod Ⅰ6 drives the sliding block 5 to retract into the fixed block 4, so that the stretched rubber strips on the fixed block 4 and the sliding block 5 are relaxed, so that the rubber strips fall from the mounting frame 3 to the collecting rod 16 in the collecting frame 15, and are concentratedly stacked under the connection of the collecting rod 16, so that it is convenient to take out the polished rubber strips in batches from the collecting frame 15 later.
