the other side of the outer gas pipeline 18 is provided with an annular sealing pipe 19; the inner gas pipeline 20 is slidingly fitted in the annular sealing pipe 19 (a rubber ring is arranged in the annular sealing pipe 19 to realize sliding sealing), one end of the inner gas pipeline 20 is provided with a sliding switch head 21, the sliding switch head 21 is slidingly fitted in the inner part of the outer gas pipeline 18 (a rubber ring is arranged on the outer side of the sliding switch head 21 to realize sliding sealing);

[0045] In the working process of the continuous film processing mechanism, through the linkage of the blowing switch cylinder 11 and the gas pipeline, the beating and cleaning of the continuous film between the umbrella skirt of the composite insulator and the cooperative operation of the component self-cleaning are realized; combined with the above connection relationship and the description of the accompanying drawings Figure 3 The working principle of the continuous film processing mechanism is as follows: When the continuous film between the umbrella skirt needs to be removed, the push head of the spraying switching cylinder 11 is extended to drive the spraying striker to move outward of the spraying treatment cavity 10, and the beating spraying head 13 on the side of the main spraying cavity 12 slides and extends along the cleaning channel 14. At this time, the outer gas pipeline 18 moves synchronously with the spraying striker, the sliding switching head 21 contacts the right sealing ring 25, and the left cleaning gas jet hole 24 is in communication. The cleaning gas pump 22 is started, high-pressure gas enters the inner gas pipeline 20 through the cleaning hose 23, flows into the outer gas pipeline 18 through the cleaning gas jet hole 24 on the left side of the sliding switching head 21, and then enters the main spraying cavity 12. The gas is sprayed through the multiple groups of channels of the beating spraying head 13: the impurity spraying channels 16 on both sides spray the umbrella skirt surface, the impurity spraying channels 16 on the front side spray the gas along the axial direction of the core rod to remove the attached continuous film debris, and the anti-sticking spraying channels 17 on the lower side continuously spray the gas to avoid the continuous film adhered to the lower surface of the beating spraying head 13. At the same time, the wedge structure on the front side of the beating spraying head 13 directly contacts the continuous film between the umbrella skirt, and cooperates with the rotation of the composite insulator (driven by the core rod driving mechanism) to knock the continuous film into the treatment box 2. When the umbrella skirt area is cleaned, the spraying switching cylinder 11 is retracted, the push head of which pulls the outer gas pipeline 18 to move rightward as a whole, and the sliding switching head 21 is in contact with the left sealing ring 25, and the right cleaning gas jet hole 24 is opened. The gas flow is diverted to enter the brush cleaning shunt pipe 27 through the cleaning bellows 26, and is blown from the shunt pipe to the flexible brush 15 on the lower side of the cleaning channel 14 to remove the impurities adhered to the root of the brush. During the retraction of the beating spraying head 13, the flexible brush 15 mechanically scrapes the lower surface of the beating spraying head 13, and the residual adhering objects are taken away by the gas flow and the brush to realize self-cleaning. The continuous film treatment mechanism has the following advantages: The continuous film treatment mechanism realizes the switching between the "umbrella skirt-core rod spraying" and "brush self-cleaning" working conditions through the gas path switching of the "sliding switching head 21-sealing ring 25". Firstly, the wedge structure of the beating spraying head 13 cooperates with the multi-directional spraying channels to efficiently remove the continuous film through mechanical beating and clean the impurities on the umbrella skirt, core rod and beating piece surface through gas spraying, solving the problem of residual debris in the traditional single beating. Secondly, the sliding switching head 21 cooperates with the sealing ring 25 to realize the switching of the gas path synchronously through the action of the spraying switching cylinder 11, without the need for additional driving components to complete the mode conversion of "beating spraying" and "brush cleaning", which is compact in structure and strong in linkage. Thirdly, the double anti-sticking design of the anti-sticking spraying channel 17 and the flexible brush 15 avoids the adhesion of the continuous film to the beating piece, and keeps the brush clean through gas backblowing to ensure stable cleaning effect in long-term use.

[0046] After the continuous film between the umbrella skirt of the composite insulator is cleaned, the continuous film at the end of the core rod also needs to be brushed and swept. Figure 10-11As shown, the two sides of the inside of the processing box 2 are respectively provided with a core rod scraping mechanism corresponding to the core rod end of the composite insulator on the two sides. Figure 11 As shown, the core rod scraping mechanism includes a scraping base frame 28 with H-shaped cross section, the lower side of the scraping base frame 28 is fixed with the bottom of the processing box 2, and the upper side of the scraping base frame 28 is respectively slidably connected with a scraping pressure shaft 29; the outer side of the scraping pressure shaft 29 is provided with a scraping shaft connecting plate 30, and the inner side of the scraping pressure shaft 29 is provided with a scraping plate 31 with arc-shaped cross section, the inside of the scraping plate 31 is provided with a steel wire brush 32, the steel wire brush 32 is used to brush the skin film on the core rod end when the composite insulator is rotated to remove the skin film on the umbrella skirt; the scraping pressure shaft 29 between the scraping base frame 28 and the scraping plate 31 is penetrated by a scraping spring 33, the scraping spring 33 is used to force the scraping plate 31 to slide inward, so that the steel wire brush 32 is in contact with the core rod end; the horizontal plate of the scraping base frame 28 is provided with a polishing cylinder 34, the push head of the polishing cylinder 34 penetrates the scraping base frame 28 and is fixed with a polishing plate 35 with arc-shaped cross section, the upper side of the polishing plate 35 is bonded with a polishing cloth 36, the polishing cloth 36 is used to polish the core rod end after the steel wire brush 32 finishes brushing the skin film on the core rod end.

[0051] The connection relationship between the casting platform 44 and the core rod supporting mechanism is as follows: In the die casting stage, the supporting cylinder 58 is in the retracted position, and the die casting lower sliding plate 50 is located directly below the die casting upper sliding plate 49; at this time, the upper supporting wheels 66 are located on the low position horizontal section of the driving zigzag plate 68, and the upper supporting heads 62 are lower than the demolding surface of the forming mold 52; after the die casting is completed, the supporting cylinder 58 is extended, and the pushing head pushes the die casting lower sliding plate 50 to move outward as a whole; under the continuous action of the upper supporting return springs 69, the upper supporting wheels 66 are always in close contact with the driving zigzag plate 68, when sliding through the rising slope of the zigzag plate, the upper supporting wheels 66 are forced to lift, and the upper supporting connecting columns 65, the upper supporting connecting plates 63 and the upper supporting shafts 61 are sequentially transmitted, so that the upper supporting heads 62 move vertically upward; the end portions of the core rods in the grooves are synchronously lifted, the composite insulator is completely separated from the forming mold 52, and the demolding without a prying rod is completed; then the supporting cylinder 58 continues to extend outward, the upper supporting wheels 66 enter the high position horizontal section of the zigzag plate and remain in the lifted state, after the workpiece is taken by manual or mechanical hand, the cylinder is reversely retracted, each component is reset in the opposite order, and the next round of die casting is prepared.

[0052] When the core rod is stuck with the forming die 52, if the core rod is directly lifted out by the rigidly connected upper supporting head 62, hard contact damage of the core rod or the forming die 52 is easily caused; in order to solve this problem, as shown in Figure 17 ; the upper supporting head 62 is flexibly matched with the upper supporting shaft 61, the lower side of the upper supporting head 62 is provided with a necked slot 70, the upper side of the upper supporting shaft 61 is slidingly matched in the necked slot 70 (the upper supporting shaft 61 is provided with an anti-extraction structure and will not be extracted out of the necked slot 70), the upper side of the upper supporting shaft 61 and the slot bottom of the necked slot 70 are provided with a buffer spring 71, the buffer spring 71 has a large stiffness coefficient and can lift out the stuck core rod; when the core rod is stuck with the forming die 52, the buffer spring 71 is compressed, and then the stuck core rod is taken out by a crowbar on one side.

[0053] After the formed composite insulator is lifted out by the core rod lifting-out mechanism, natural cooling and air cooling are needed; as shown in Figure 18 , the discharge side of the adjustable casting device is provided with a small mechanical arm 72, the execution end of the small mechanical arm 72 is provided with an air-cooled lifting mechanism; the air-cooled lifting mechanism is used for air-cooling the formed composite insulator; as shown in Figure 19-20 , the air-cooled lifting mechanism includes an L-shaped cross-section air-cooled base frame 73; the air-cooled base frame 73 is provided with an air-cooled air pump 74 and an air-cooled cavity 75, the air outlet end of the air-cooled air pump 74 is communicated with the inside of the air-cooled cavity 75 through an air-cooled hose 76; the formed composite insulator is sprayed and cooled by the air flow sprayed by the air-cooled air pump 74 to the air-cooled cavity 75; as shown in ​As shown, the air cooling cavity 75 is a cylindrical cavity structure with an opening on the lower side, and the lower side of the air cooling cavity 75 is fixed with the upper supporting ring 78 through the air cooling corrugated pipe 77; the air cooling rotating plate 79 is rotatably fitted in the upper supporting ring 78, and the air cooling rotating plate 79 is provided with the air blowing hole 80; the air cooling driving motor 82 is installed on the upper side of the air cooling cavity 75 through the motor bracket 81, the motor shaft of the air cooling driving motor 82 is fixed with one end of the rotating column 83 through the shaft coupling, the other end of the rotating column 83 is fixed with the air cooling ring bracket 84, the air cooling ring bracket 84 is a frame structure, the lower side of the air cooling ring bracket 84 is slidably fitted with the linkage column 85, the lower side of the linkage column 85 is fixed with the upper side of the air cooling rotating plate 79, the upper side of the linkage column 85 is provided with the anti-falling structure, which can avoid the linkage column 85 from falling out of the air cooling ring bracket 84, the linkage column 85 between the air cooling ring bracket 84 and the air cooling rotating plate 79 is penetrated by the air cooling return spring 86; the air cooling ring bracket 84 is provided with the active pull ring 87 on the upper side, the lower side of the active pull ring 87 is connected with one end of the pulling rope 88, the other end of the pulling rope 88 is fixed with the anti-falling structure on the upper side of the air cooling ring bracket 84 and the linkage column 85 (the upper side of the air cooling ring bracket 84 is provided with the passage allowing the pulling rope 88 to pass through); the air cooling cavity 75 is provided with the air cylinder bracket 89 with an n-shaped cross section on the upper side, the air cylinder bracket 89 is provided with the linkage air cylinder 90, the push head of the linkage air cylinder 90 penetrates out of the air cylinder bracket 89 downward and is fixed with the linkage plate 91, the lower side of the linkage plate 91 is oppositely provided with two linkage shafts 92, the linkage shafts 92 are slidably fitted with the upper side of the air cooling cavity 75, and the lower end of the linkage shaft 92 is fixed with the electromagnet 93; the air cooling ring bracket 84 and the air cooling rotating plate 79 are driven to rotate as a whole by the air cooling driving motor 82, so as to change the relative position of the air blowing hole 80 and blow and cool the formed composite insulator; when the core rod and the forming die 52 are stuck, the electromagnet 93 is used to adsorb the active pull ring 87, the upper supporting ring 78 and the air cooling rotating plate 79 are pulled to move upward, the electromagnet 93 releases the active pull ring 87, and the air cooling rotating plate 79 performs one-side knocking upward on the core rod.

[0056] The wind cooling supporting mechanism has the beneficial effects that: The wind cooling and demolding auxiliary functions are integrated in the same wind cooling supporting mechanism; in the wind cooling stage, the rotating air jet hole 80 is used to uniformly cool the insulator in the circumferential direction; in the knocking stage, the linear displacement of the cylinder is enlarged to the rapid impact stroke of the wind cooling rotating plate 79 through the transient linkage of the electromagnet 93-pulling rope 88-corrugated pipe; the knocking structure formed by the linkage cylinder 90 and the electromagnet 93 cooperates to form a stuck emergency processing mechanism, realizes automatic knocking demolding, reduces the operation risk and protects the core rod and the mold from hard damage.
