[0044] When the sliding sleeve 10 slides to the top of the fixed column 3, the contact sleeve ring 29 is jacked up by the fixed ring 25, the jacking disc 42 is jacked up by the jacking rod 41 when the contact sleeve ring 29 is jacked up, so that the feeding column 15 is jacked up, and the grid openings 36 on the outer surface of the feeding column 15 slide into the inside of the cap sleeve 18 during the jacking process, so that the material in the hopper 2 reciprocally enters the inside of the temporary storage cavity 35, at this time the sealing block 38 is pressed downward by the bottom of the pressure rod 19, so that the sealing cavity 37 and the temporary storage cavity 35 are in communication, at this time the material in the temporary storage cavity 35 flows into the inside of the mixing barrel 1 from the bottom of the sealing cavity 37, when the temporary storage assembly is not triggered, the plurality of grid openings 36 on the top of the feeding column 15 are below the cap sleeve 18, at this time the material in the hopper 2 can enter the inside of the temporary storage cavity 35 through the grid openings 36, and the bottom of the pressure rod 19 does not contact the sealing block 38, the sealing block 38 and the top of the sealing cavity 37 are sealed from each other under the jacking force of the jacking spring 39, so as to prevent the material in the temporary storage cavity 35 from flowing into the sealing cavity 37.

[0047] For example, in an embodiment, the present application also provides a preparation method of weather-resistant power cable material, which is applied to the preparation equipment of weather-resistant power cable material as above, and comprises the following steps:

[0048] Step S1: when the raw materials for producing the cable material are mixed, the raw materials need to be placed in the inside of the mixing barrel 1, and the special materials are placed in the inside of the hopper 2, in the mixing process, the raw materials in the inside of the mixing barrel 1 are stirred and turned over from bottom to top by the motor 5 driving the turnover assembly, at the same time, when the turnover assembly slides to the upper side, it triggers the temporary storage assembly to make the special materials flow into the inside of the mixing barrel 1, and at the same time, the discharging port 33 of the fixed column 3 is triggered by the trigger mechanism, so that the materials in the inside of the mixing barrel 1 flow out;

[0049] Step S2: When the turnover assembly is working, the sliding sleeve 10 will slide up and down along the guide rods 22 while rotating, so that the stirring rods 12 on the outer surface of the sliding sleeve 10 can stir the material in the mixing barrel 1, and at the same time, the material is turned over by the spiral blades 11 to make the mixing more uniform. While the sliding sleeve 10 is sliding, the rhombus cursor 23 on the inside slides along the forward slide 26 and the reverse slide 27, so that the sliding sleeve 10 can slide up and down on the outer surface of the fixed column 3, improving the efficiency of turnover and stirring and the uniformity of material mixing;

[0050] Step S3: When the sliding sleeve 10 slides to the top area of the fixed column 3, the contact sleeve ring 29 is lifted up by the fixed ring 25, and the lifting disc 42 is lifted up by the lifting rod 41 when the contact sleeve ring 29 is lifted up, so that the feeding column 15 is lifted up. In the process of lifting, the grid port 36 on the outer surface of the feeding column 15 slides into the inside of the cap sleeve 18, so that the material in the hopper 2 reciprocally enters the inside of the temporary storage cavity 35. At this time, the sealing block 38 is pressed down by the pressing rod 19 at the bottom, so that the sealing cavity 37 is in communication with the temporary storage cavity 35. At this time, the material in the temporary storage cavity 35 can flow from the bottom of the sealing cavity 37 into the inside of the mixing barrel 1;

[0051] Step S4: When the contact sleeve ring 29 slides up, the bridge rod 31 is driven to slide up, so that the connecting disc 32 slides up in the inside of the discharge cavity 30, and the sealing baffle 34 slides up above the discharge port 33 to open the discharge port 33. At this time, the mixed material in the mixing barrel 1 can flow out through the discharge port 33.

[0052] The device is used in practice: at present, when the materials are mixed, the existing equipment generally places the raw materials and mixed main materials in the stirring barrel, and then uses stirring screws or stirring claws for mixing and stirring. However, when special mixing substances need to be added intermittently, the time interval and quantity of the special substances cannot be controlled, resulting in uneven mixing. In the present application, when the sliding sleeve 10 slides to the top area of the fixed column 3, the contact sleeve ring 29 is lifted upward through the fixed ring 25. When the contact sleeve ring 29 is lifted upward, the lifting disc 42 is lifted upward through the lifting rod 41, so that the feeding column 15 is lifted upward. In the lifting process, the grid openings 36 on the outer surface of the feeding column 15 slide into the inside of the cap sleeve 18, so that the materials in the hopper 2 reciprocally enter the inside of the temporary storage cavity 35. At this time, the sealing block 38 is pressed downward through the bottom of the pressing rod 19, so that the sealing cavity 37 is communicated with the temporary storage cavity 35. At this time, the substances in the temporary storage cavity 35 can flow into the inside of the mixing barrel 1 from the bottom of the sealing cavity 37. When the temporary storage assembly is not triggered, the plurality of grid openings 36 on the top of the feeding column 15 are located below the cap sleeve 18. At this time, the materials in the hopper 2 can enter the inside of the temporary storage cavity 35 through the grid openings 36. Meanwhile, the bottom of the pressing rod 19 does not contact the sealing block 38. Under the lifting force of the lifting spring 39, the sealing block 38 and the top of the sealing cavity 37 are sealed from each other, so as to prevent the substances in the temporary storage cavity 35 from flowing into the sealing cavity 37. By controlling the reciprocating movement of the feeding column 15, the intermittent feeding between the materials can be realized, so as to gradually add the special substances, and the adding interval time is the same.
