The preparation method for weather-resistant power cable material includes the following steps: Step S1: When mixing the raw materials for producing the cable material, the raw materials need to be placed inside the mixing cylinder, and the special materials need to be placed inside the hopper. During the mixing process, the motor drives the material turning assembly to stir and turn the raw materials inside the mixing cylinder from bottom to top. At the same time, when the material turning assembly slides to the upper part, it will trigger the temporary storage assembly to make the special materials flow into the interior of the mixing cylinder. At the same time, it will also trigger the outlet of the fixed column through the triggering mechanism to make the materials inside the mixing cylinder flow out; Step S2: When the material turning component works, the sliding sleeve will slide up and down along multiple guide rods while rotating, so that the stirring rods on the outer surface of the sliding sleeve stir the materials inside the mixing cylinder. At the same time of stirring, the materials are turned over by the spiral blades, making the mixing more uniform.

During the jacking process, the grid openings on the outer surface of the feeding column slide into the inside of the cap sleeve, so that the materials in the hopper reciprocally enter the inside of the temporary storage cavity. At this time, by pressing down the sealing block at the bottom of the pressing rod, the sealing cavity can be communicated with the temporary storage cavity, and the materials inside the temporary storage cavity can flow into the inside of the mixing cylinder from the bottom of the sealing cavity; Step S4: When the triggering mechanism works, when the contact collar slides up, it will drive the bridging rod to slide up, thus driving the connecting plate to slide up inside the discharge cavity, making the sealing flap slide above the discharge port to open the discharge port. At this time, the materials mixed inside the mixing cylinder can flow out through the discharge port.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting the material turning component, the raw materials inside the mixing cylinder can be turned over and stirred when mixing the raw materials for producing the cable material, making the mixing more uniform. At the same time, the material turning component can also trigger the temporary storage component to send the special materials stored inside into the mixing cylinder for mixing. By setting the temporary storage component, the special materials can be temporarily stored and supplied to the inside of the mixing cylinder in cooperation with the material turning component. By setting the triggering mechanism, the discharge of the materials inside the mixing cylinder can be controlled and interlocked with the temporary storage component. When the material turning component slides to the upper part, it will trigger the temporary storage component to make the special materials flow into the mixing cylinder. At the same time, it will also trigger the discharge port of the fixed column through the triggering mechanism to make the materials inside the mixing cylinder flow out; 2. When the material turning component works, the sliding sleeve will slide up and down along multiple guide rods and rotate at the same time, so that the stirring rods on the outer surface of the sliding sleeve stir the materials inside the mixing cylinder, and at the same time of stirring, the materials are turned over by the spiral blades, making the mixing more uniform. While the sliding sleeve slides, the diamond cursor inside slides along the forward slideway and the reverse slideway, so that the sliding sleeve can slide up and down reciprocally on the outer surface of the fixed column, improving the efficiency of material turning and stirring and the uniformity of material mixing; 3. When the temporary storage component works, when the sliding sleeve slides to the top area of the fixed column, it will jack up the contact sleeve ring through the fixed ring. When the contact sleeve ring is jacked up, it will jack up the jacking disc through the jacking rod, so that the feeding column is jacked up. During the jacking process, the grid openings on the outer surface of the feeding column slide into the inside of the cap sleeve, so that the materials in the hopper enter the temporary storage cavity reciprocally. At this time, by pressing down the sealing block at the bottom of the pressing rod, the sealing cavity can be communicated with the temporary storage cavity, and the substances inside the temporary storage cavity can flow into the inside of the mixing cylinder from the bottom of the sealing cavity; 4. When the triggering mechanism works, when the contact sleeve ring slides up, it will drive the bridging rod to slide up, thereby driving the connecting disc to slide up inside the discharge cavity, making the sealing flap slide above the discharge port to open the discharge port. At this time, the mixed materials inside the mixing cylinder can flow out through the discharge port. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-11 , the present invention provides a technical solution: a weather-resistant power cable material preparation device, including a mixing cylinder 1, a hopper 2 is fixed on the top of the mixing cylinder 1, the top of the mixing cylinder 1 is closed, a fixed column 3 is fixed on the inner top surface of the mixing cylinder 1, the bottom of the fixed column 3 penetrates to the lower part of the mixing cylinder 1, a material turning assembly is arranged on the outer side of the fixed column 3, a plurality of temporary storage assemblies are arranged on the top of the mixing cylinder 1, a mushroom rack 8 is fixed on the inner bottom surface of the hopper 2, a reciprocating cavity 43 is opened near the top edge inside the fixed column 3, and a triggering mechanism is arranged inside the reciprocating cavity 43; The bottom of the mixing cylinder 1 is open, and an annular groove 20 is provided on the inner wall of the bottom opening of the mixing cylinder 1. A gear ring 7 is rotatably arranged on the outer surface of the fixed column 3 near the bottom edge. An annular ring 21 is fixed to the top of the gear ring 7, and the annular ring 21 is slidably engaged inside the annular groove 20. A frame 4 is fixed on the outer surface of the fixed column 3 near the bottom edge. A motor 5 is fixed on the frame 4, and a driving gear 6 is fixed to the output end of the motor 5. The driving gear 6 meshes with the gear ring 7. A guide plate 9 is obliquely fixed between the inner walls of the mixing cylinder 1, and the inner side of the guide plate 9 extends obliquely downward to the lower part of the mixing cylinder 1 and is located outside the material turning assembly.

[0020] The achieved effect is that by setting the material turning assembly, the raw materials inside the mixing cylinder 1 can be turned and stirred during the mixing production of cable material raw materials, making the mixing more uniform. At the same time, the material turning assembly can also trigger the temporary storage assembly to send the special materials stored inside into the mixing cylinder 1 for mixing. By setting the temporary storage assembly, the special materials can be temporarily stored and supplied to the inside of the mixing cylinder 1 in cooperation with the material turning assembly. By setting the triggering mechanism, the discharge of the materials inside the mixing cylinder 1 can be controlled and interlocked with the temporary storage assembly. When the material turning assembly slides to the upper part, it will trigger the temporary storage assembly to make the special materials flow into the mixing cylinder 1. At the same time, it will also trigger the discharge port 33 of the fixed column 3 through the triggering mechanism to make the materials inside the mixing cylinder 1 flow out. When the material turning assembly flips the materials, due to the obliquely arranged guide plate 9, the space between its inner side and the components on the outer surface of the fixed column 3 is small, so as to ensure that the materials above can be fully mixed before flowing into the lower part.

[0021] Such as Figure 1 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown in the figure, the material turning component includes a sliding sleeve 10. An auxiliary ring 24 is rotatably arranged on the inner top surface of the mixing cylinder 1. A plurality of guide rods 22 are fixedly arranged at equal intervals along the circumferential direction at the bottom of the auxiliary ring 24. The bottoms of the plurality of guide rods 22 are correspondingly fixed on the top of the gear ring 7. The sliding sleeve 10 is slidably connected between the outer surfaces of the plurality of guide rods 22, and the inner wall of the sliding sleeve 10 is in mutual fit with the outer surface of the fixed column 3. A forward slideway 26 is spirally arranged on the outer surface of the fixed column 3, and a reverse slideway 27 is spirally arranged on the outer surface of the fixed column 3. The forward slideway 26 and the reverse slideway 27 intersect and penetrate each other, and the two ends of the forward slideway 26 and the reverse slideway 27 are mutually communicated. A diamond cursor 23 is rotatably arranged on the inner wall of the sliding sleeve 10, and the diamond cursor 23 is slidably engaged inside the forward slideway 26. A spiral blade 11 is fixed at the middle part of the outer surface of the sliding sleeve 10. A plurality of stirring rods 12 are fixedly arranged at equal intervals along the circumferential direction near the top of the outer surface of the sliding sleeve 10. A notch 28 is arranged at the edge near the top of the outer surface of the fixed column 3. A fixed ring 25 is fixed at the edge near the top of the inner wall of the sliding sleeve 10, and the inner wall of the fixed ring 25 is in mutual fit with the inner wall of the notch 28.

[0022] The achieved effect is that while the sliding sleeve 10 slides up and down along the plurality of guide rods 22, it rotates, so that the stirring rods 12 on the outer surface of the sliding sleeve 10 stir the materials inside the mixing cylinder 1, and while stirring, the spiral blade 11 turns the materials, making the mixing more uniform. While the sliding sleeve 10 slides, the diamond cursor 23 inside slides along the forward slideway 26 and the reverse slideway 27, so that the sliding sleeve 10 can slide up and down reciprocally on the outer surface of the fixed column 3, improving the efficiency of material turning and stirring and the uniformity of material mixing. When sliding downwards, the diamond cursor 23 slides along the forward slideway 26. When sliding to the bottom communication part of the forward slideway 26 and the reverse slideway 27, under the guidance of the communication part, the diamond cursor 23 slides from the forward slideway 26 into the reverse slideway 27, and at this time, the sliding sleeve 10 can be driven to slide upwards. By reciprocating in this way, the function of reciprocally turning and stirring the materials inside the mixing cylinder 1 can be realized.

[0023] Such as Figure 2 、 Figure 3 and Figure 11As shown, the temporary storage component includes a feeding column 15. A cap sleeve 18 is fixed at the bottom of the mushroom rack 8 near the outer surface edge. An adjustment cavity 13 is formed at the middle of the top of the mixing cylinder 1, and a movable cavity 14 is formed near the edge of the top of the mixing cylinder 1. The feeding column 15 is arranged inside the movable cavity 14. The top of the feeding column 15 slides through to the upper side of the mixing cylinder 1 and extends into the cap sleeve 18. The bottom of the feeding column 15 slides through to the inside of the mixing cylinder 1. A side port 16 penetrating into the inside of the movable cavity 14 is formed on the inner wall of the adjustment cavity 13. A jacking plate 42 is slidably arranged between the inner walls of the adjustment cavity 13. A guiding plate 17 is fixed on the outer surface of the jacking plate 42. The guiding plate 17 is slidably engaged between the inner walls of the side port 16, and one end of the guiding plate 17 extends into the movable cavity 14. A protrusion is arranged on the outer surface of the feeding column 15. One end of the guiding plate 17 extends below the protrusion. A downward pressing spring 40 is fixed at the top of the movable cavity 14, and the bottom of the downward pressing spring 40 is fixed on the protrusion. A temporary storage cavity 35 is formed at the middle of the inside of the feeding column 15. A plurality of grid openings 36 are equidistantly arranged along the circumferential direction near the top edge of the outer surface of the temporary storage cavity 35. A sealing cavity 37 is formed near the bottom edge of the inside of the feeding column 15. The top of the sealing cavity 37 is communicated with the bottom of the temporary storage cavity 35, and the bottom of the sealing cavity 37 penetrates to the lower side of the feeding column 15. A pressing rod 19 is fixed at the inner side of the cap sleeve 18 at the bottom of the mushroom rack 8. The bottom of the pressing rod 19 slides through to the inside of the temporary storage cavity 35. A sealing block 38 is arranged inside the sealing cavity 37. A jacking spring 39 is fixed at the bottom of the sealing block 38, and the bottom of the jacking spring 39 is fixed on the inner bottom surface of the sealing cavity 37.

[0024] The achieved effect is that when the sliding sleeve 10 slides to the top area of the fixed column 3, the contact sleeve ring 29 will be jacked up by the fixed ring 25. When the contact sleeve ring 29 is jacked up, the jacking plate 42 will be jacked up by the jacking rod 41, so as to jack up the feeding column 15. During the jacking process, the grid openings 36 on the outer surface of the feeding column 15 slide into the cap sleeve 18, so that the materials in the hopper 2 reciprocally enter the temporary storage cavity 35. At this time, by pressing the sealing block 38 downward with the bottom of the pressing rod 19, the sealing cavity 37 can be communicated with the temporary storage cavity 35. At this time, the substances in the temporary storage cavity 35 can flow into the mixing cylinder 1 from the bottom of the sealing cavity 37. When the temporary storage component is not triggered, the plurality of grid openings 36 at 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 temporary storage cavity 35 through the grid openings 36. At the same time, the bottom of the pressing rod 19 does not contact the sealing block 38. Under the jacking force of the jacking spring 39, the sealing block 38 is sealed with the top of the sealing cavity 37, so as to prevent the substances in the temporary storage cavity 35 from flowing into the sealing cavity 37.

[0025] Such as Figure 3 , Figure 5 , Figure 8 andFigure 10 As shown in Figure 10 , the triggering mechanism includes a cross-shaped slide plate 45. A contact collar 29 is slidably arranged between the inner walls of the notch 28. An annular cavity 47 is formed at the top of the notch 28. The contact collar 29 is located below the annular cavity 47. Four guiding ports 44 penetrating through to the notch 28 are formed on the inner wall of the reciprocating cavity 43. The cross-shaped slide plate 45 is slidably arranged between the inner wall of the reciprocating cavity 43 and the inner walls of the plurality of guiding ports 44. Four ends of the cross-shaped slide plate 45 are respectively and fixedly connected to the inner wall of the contact collar 29. A reciprocating spring 46 is fixed to the top of the cross-shaped slide plate 45. The top of the reciprocating spring 46 is fixed to the inner top surface of the reciprocating cavity 43. A jacking rod 41 is fixed to the top of the cross-shaped slide plate 45. The top of the jacking rod 41 slidably penetrates into the inside of the adjusting cavity 13, and the top of the jacking rod 41 is fixed to the bottom of the jacking disc 42. A discharge cavity 30 is formed near the bottom edge inside the fixed column 3. A bridging rod 31 is fixed to the bottom of the cross-shaped slide plate 45. The bottom of the bridging rod 31 slidably penetrates into the inside of the discharge cavity 30. A plurality of discharge ports 33 penetrating through to the outer surface of the fixed column 3 are formed on the inner wall of the discharge cavity 30. A connecting disc 32 is slidably arranged between the inner walls of the discharge cavity 30. The bottom of the bridging rod 31 is fixed to the top of the connecting disc 32. A sealing flap 34 is fixed to the bottom of the connecting disc 32 near the outer surface edge. The sealing flap 34 is located inside the opening of the discharge port 33.

[0026] The achieved effect is that when the contact collar 29 slides upward, it will drive the bridging rod 31 to slide upward, thereby driving the connecting disc 32 to slide upward inside the discharge cavity 30, causing the sealing flap 34 to slide above the discharge port 33 to open the discharge port 33. At this time, the mixed material inside the mixing cylinder 1 can flow out through the discharge port 33. During subsequent resetting, the elastic pressure of the reciprocating spring 46 can press the cross-shaped slide plate 45 downward, facilitating subsequent resetting. Moreover, during the sliding process, the end of the cross-shaped slide plate 45 is slidably engaged between the inner walls of the guiding ports 44, which can ensure the stability of its sliding.

[0027] For example, in one embodiment, the present invention further provides a preparation method for weather-resistant power cable material, which is applied to a weather-resistant power cable material preparation device as described above, including the following steps: Step S1: When mixing the raw materials for producing the cable material, the raw materials need to be placed inside the mixing cylinder 1, and the special materials need to be placed inside the hopper 2. During the mixing process, the motor 5 drives the material turning assembly to stir and turn the raw materials inside the mixing cylinder 1 from bottom to top. At the same time, when the material turning assembly slides to the upper part, it will trigger the temporary storage assembly to make the special materials flow into the mixing cylinder 1. Meanwhile, it will also trigger the discharge port 33 of the fixed column 3 through the triggering mechanism, so that the materials inside the mixing cylinder 1 flow out; Step S2: When the material turning component works, the sliding sleeve 10 will slide up and down along multiple guide rods 22 and rotate at the same time, so that the stirring rods 12 on the outer surface of the sliding sleeve 10 stir the materials inside the mixing cylinder 1, and at the same time, the spiral blades 11 turn the materials, making the mixing more uniform. While the sliding sleeve 10 slides, the diamond cursor 23 inside slides along the forward slideway 26 and the reverse slideway 27, so that the sliding sleeve 10 can slide up and down reciprocally on the outer surface of the fixed column 3, improving the efficiency of material turning and stirring and the uniformity of material mixing; Step S3: When the temporary storage component works, when the sliding sleeve 10 slides to the top area of the fixed column 3, it will jack up the contact collar 29 through the fixed ring 25. When the contact collar 29 is jacked up, it will jack up the jacking plate 42 through the jacking rod 41, so that the feeding column 15 is jacked up. During the jacking process, the grid openings 36 on the outer surface of the feeding column 15 slide into the inside of the capping sleeve 18, so that the materials in the hopper 2 reciprocally enter the temporary storage cavity 35. At this time, by pressing down the sealing block 38 through the bottom of the pressing rod 19, the sealing cavity 37 can be communicated with the temporary storage cavity 35, and the materials in the temporary storage cavity 35 can flow into the inside of the mixing cylinder 1 from the bottom of the sealing cavity 37; Step S4: When the triggering mechanism works, when the contact collar 29 slides up, it will drive the bridging rod 31 to slide up, thus driving the connecting disk 32 to slide up inside the discharge cavity 30, making the sealing flap 34 slide above the discharge port 33 to open the discharge port 33. At this time, the mixed materials inside the mixing cylinder 1 can flow out through the discharge port 33.

[0028] The use of this device in practice: Currently, when mixing materials, existing equipment generally places the raw materials and the main mixed materials together inside the mixing barrel, and then uses a mixing screw or mixing claws for mixing. However, when it is necessary to intermittently add special mixed substances midway, it is impossible to control the time interval and quantity of the addition of the special substances, resulting in uneven mixing. In this application, when the sliding sleeve 10 slides to the top area of the fixed column 3, the contact collar 29 will be jacked up by the fixed ring 25. When the contact collar 29 is jacked up, the jacking plate 42 will be jacked up by the jacking rod 41, so that the feeding column 15 is jacked up. During the jacking 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 temporary storage cavity 35. At this time, by pressing the sealing block 38 downward with the bottom of the pressure rod 19, the sealing cavity 37 can be 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 cylinder 1 from the bottom of the sealing cavity 37. When the temporary storage component is not triggered, the multiple grid openings 36 at 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 temporary storage cavity 35 through the grid openings 36. At the same time, the bottom of the pressure rod 19 does not contact the sealing block 38, and under the jacking force of the jacking spring 39, the sealing block 38 is sealed with the top of the sealing cavity 37, thereby preventing the substances in the temporary storage cavity 35 from flowing into the sealing cavity 37. By controlling the up and down reciprocating movement of the feeding column 15, intermittent feeding of the materials can be carried out to gradually add special substances and make the addition interval time the same.
