[0016] Technical effects and advantages of the present invention:

[0017] 1. When the driving motor drives the U-shaped frame and the silicone head to rotate, the shade-dried insulator clay blank can be driven to rotate. While the insulator clay blank is rotating, multiple metal rotating balls can be driven to rotate. If protrusions and burrs are generated on the outside of the insulator clay blank, multiple rotating metal rotating balls can rub the outside of the insulator clay blank to remove the protrusions and burrs, thereby preventing the burrs and protrusions from affecting the quality of the insulator clay blank. Furthermore, when the insulator clay blank is pressed down into the groove, a sealed space is formed between the insulator clay blank and the inside of the groove. When the paint is sprayed out, the paint can be prevented from leaking, thereby saving raw materials.

[0018] 2. After rotating for a certain period of time, the spray paint sucked by the suction pump can be discharged from the gap between the metal rotating ball and the discharge trough. The paint is in a liquid state. Since the metal rotating ball is in a state of continuous rotation, the metal rotating ball can always drive the spray paint out, and finally the paint is smeared on the bottom end of the insulator mud blank. When the suction power of the suction pump increases and the discharge pressure increases, the paint can be sprayed out from the gap between the metal rotating ball and the discharge trough. With the rotation of the metal rotating ball, the paint can be evenly applied to the outside of the insulator mud blank, and the rotation of the metal rotating ball can squeeze the paint to adhere to the insulator mud blank.

[0019] 3. In addition, an electric heating wire is provided inside the truncated table. When the electric heating wire is started, the groove can be heated. The sealed space formed by the insulator clay blank and the groove can avoid heat loss and preliminarily dry the paint so that the paint adheres to the outside of the insulator clay blank and is not easy to fall off. At the same time, multiple metal rotating balls are made of metal and can quickly absorb heat. The multiple metal rotating balls can transfer the absorbed heat to the insulator clay blank to speed up the drying speed of the paint.

[0020] 4. When the coating is completed, the cylinder can be started to retract, driving the silicone head to rise. Since the silicone head and the insulator clay blank are in an adsorption connection state, the insulator clay blank will be driven to rise, so that the insulator clay blank will be separated from the groove, and a height will be created between the insulator clay blank and the groove. The insulator clay blank can be rotated by driving the motor, driving the surrounding air to rotate, and the heat generated in the groove can be used to spin dry the outside of the insulator clay blank, so that the coating is completely dry, thereby improving the drying efficiency.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clearly described in detail. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides Figure 1 - Figure 4 The spray drying device for applying glaze on the surface of porcelain insulators which can improve drying efficiency is shown, and includes a support frame 1, a center table 3 is fixedly connected to the middle of the top of the support frame 1, a round table 6 is fixedly connected to the top of the center table 3, the support frame 1 is configured to be cylindrical, and a plurality of conveying rollers 2 are rotatably connected to the outer side of the top of the support frame 1, and the plurality of conveying rollers 2 are distributed around the center table 3. Materials can be conveyed by the plurality of conveying rollers 2, so that the materials can be moved close to the round table 6 to facilitate operation by personnel.

[0028] It should be noted that a reduction motor may be installed on the side of the support frame 1 to control the rotation speed and normal transmission of the conveying roller 2. This is a common existing technology and will not be described in detail here.

[0029] A groove is provided at the top of the truncated table 6, and a plurality of discharge troughs are provided inside the groove. Metal rotating balls 20 are rotatably connected to the plurality of discharge troughs. A suction pump 5 is provided on one side of the truncated table 6, and a sealing ring is provided on the top of the truncated table 6. A storage box 4 is fixedly connected to one side of the support frame 1. An inner liner is provided inside the truncated table 6, and a cavity is provided in the inner liner. The cavity is connected to the plurality of discharge troughs. The storage box 4, the suction pump 5 and the cavity are connected in sequence through pipelines. In the actual operation of the present invention, spray paint can be put into the storage box 4, and the spray paint can be drawn into the discharge trough by the suction pump 5 to complete the spraying operation.

[0030] In the actual operation of the present invention, since the porcelain insulator needs to make clay blanks first, after the clay blanks are dried in the shade and have a certain hardness, they can be glazed. After the glazing process, a drying device is required to dry the glaze on its surface, and then the whole is fired. Therefore, a gap is left between the multiple discharge troughs and the corresponding metal rotating balls 20, and a spacing is provided between the outer side of the truncated cone 6 and the inner tank. An electric heating wire is provided in the spacing. The shade-dried insulator clay blank 24 can be clamped in the groove, and the outer side of the insulator clay blank 24 is attached to the surface of the multiple metal rotating balls 20. An adsorption mechanism is provided above the insulator clay blank 24, and a discharge port 21 is opened at the bottom of the groove, and a leak plugging mechanism is provided inside the discharge port 21.

[0031] A fixing frame 7 is fixed to the bottom end of the support frame 1, a connecting plate 8 is fixed to one side of the fixing frame 7, a driving motor 9 is fixed to the top of the connecting plate 8, a driving shaft is arranged at the bottom of the driving motor 9, a U-shaped frame 10 is fixedly connected to the bottom end of the driving shaft, a fixing plate 12 is fixed to the bottom of the U-shaped frame 10, a silicone head 13 is arranged at the bottom end of the fixing plate 12, the silicone head 13 is attached to the upper surface of the insulator mud blank 24, and the driving motor 9 is started to drive the U-shaped frame 10 and the silicone head 13 to rotate.

[0032] The U-shaped opening of the U-shaped frame 10 is downward, and a cylinder 11 is arranged inside the U-shaped frame 10. A protruding end is arranged at the bottom end of the cylinder 11. The protruding end passes through a fixed plate 12, and the bottom end of a silicone head 13 is fixed to the bottom of the protruding end. The adsorption mechanism includes an adsorption pump 14, and the adsorption pump 14 is fixed to one side of the U-shaped frame 10. A plurality of adsorption holes 15 are provided on the outside of the silicone head 13, and an air cavity is provided inside the silicone head 13. A connecting pipe 16 is connected between the air cavity and the adsorption pump 14, and the plurality of adsorption holes 15 are connected to the air cavity. When the adsorption pump 14 is started, the plurality of adsorption holes 15 generate suction, and when the silicone head 13 contacts and extrude the insulator mud blank 24, the insulator mud blank 24 can be adsorbed and connected.

[0033] In the actual operation of the present invention, the shade-dried insulator clay blank 24 can be placed inside the groove, and by starting the cylinder 11, the extended end of the cylinder 11 drives the silicone head 13 to press down. While pressing down, the silicone head 13 can squeeze the upper surface of the insulator clay blank 24. At the same time, with the adsorption of the adsorption holes 15, a connection can be generated between the insulator clay blank 24 and the silicone head 13, and the insulator clay blank 24 can be stuck in the groove, and the bottom end of the insulator clay blank 24 can contact multiple metal rotating balls 20.

[0034] When the driving motor 9 drives the U-shaped frame 10 and the silicone head 13 to rotate, the insulator clay blank 24 can be driven to rotate. While the insulator clay blank 24 rotates, multiple metal rotating balls 20 can be driven to rotate. If protrusions and burrs are generated on the outer side of the insulator clay blank 24, multiple rotating metal rotating balls 20 can rub the outer side of the insulator clay blank 24 to remove the protrusions and burrs, thereby preventing the burrs and protrusions from affecting the quality of the insulator clay blank 24.

[0035] After rotating for a certain period of time, the spray paint sucked by the suction pump 5 can be discharged from the gap between the metal rotating ball 20 and the discharge trough. The paint is in a liquid state and can lubricate the metal rotating ball 20 and the insulator mud blank 24. Since the metal rotating ball 20 is in a state of continuous rotation, the metal rotating ball 20 can always drive the spray paint out, and finally the paint is applied to the bottom end of the insulator mud blank 24, and when the suction power of the suction pump 5 increases and the discharge pressure increases, the paint can be sprayed out from the gap between the metal rotating ball 20 and the discharge trough. With the rotation of the metal rotating ball 20, the paint can be evenly applied to the outside of the insulator mud blank 24, and the rotation of the metal rotating ball 20 can squeeze the paint to adhere to the insulator mud blank 24.

[0036] It should be noted that the insulator clay blank 24 is glazed and then fired to form a shape, and after forming, the steel legs and other metal accessories are fixed to the upper end of the insulator clay blank 24 by gluing.

[0037] Furthermore, when the insulator clay blank 24 is pressed down into the groove, the insulator clay blank 24 and the inside of the groove form a sealed space, and when the paint is sprayed out, leakage of the paint can be avoided, thereby saving raw materials.

[0038] It should be noted that multiple metal rotating balls 20 can be staggered to facilitate the multiple metal rotating balls 20 to evenly apply extrusion coating to the insulator mud blank 24, and the distribution quantity and position of the metal rotating balls 20 can be arranged according to actual needs. The schematic diagram of the present invention is for reference only.

[0039] In addition, an electric heating wire is provided inside the truncated table 6. When the electric heating wire is started, the groove can be heated. The sealed space formed by the insulator clay blank 24 and the inside of the groove can avoid heat loss and preliminarily dry the paint so that the paint adheres to the outside of the insulator clay blank 24 and is not easy to fall off. At the same time, multiple metal rotating balls 20 are made of metal and can quickly absorb heat. The multiple metal rotating balls 20 can transfer the absorbed heat to the insulator clay blank 24 to accelerate the drying speed of the paint.

[0040] When the coating is completed, the cylinder 11 can be started to retract the cylinder 11, driving the silicone head 13 to rise. Since the silicone head 13 and the insulator clay blank 24 are in an adsorption connection state, the insulator clay blank 24 will be driven to rise, so that the insulator clay blank 24 is separated from the groove, and a height is generated between the insulator clay blank 24 and the groove. The insulator clay blank 24 is driven to rotate by the driving motor 9, and the surrounding air is driven to rotate. With the heat generated in the groove, the outside of the insulator clay blank 24 can be dried to make the coating completely dry.

[0041] The leak-proof mechanism includes an electric push rod 17 and a collecting box 18. The collecting box 18 is fixedly connected to the bottom end of the support frame 1. The electric push rod 17 is fixed to the bottom end of the collecting box 18. The collecting box 18 is connected to the groove. A telescopic end 22 is provided at the top of the electric push rod 17. The top of the telescopic end 22 passes through the collecting box 18, and a plug 23 is connected to the top of the passing end. The plug 23 is elastic and is engaged with the inside of the discharge port 21. The width of the plug 23 is greater than the width of the telescopic end 22.

[0042] In the actual operation of the present invention, after the coating is completed, the electric push rod 17 can be started, and the electric push rod 17 can rise, so that the plug 23 can rise and separate from the discharge port 21. Since the radius of the telescopic end 22 is smaller than the radius of the plug 23, the excess coating can enter the interior of the collecting box 18 along the telescopic end 22, thereby completing the collection of the remaining material. At the same time, when the telescopic end 22 rises, the bottom end of the insulator mud blank 24 can be lifted up, and the contraction of the cylinder 11 can be coordinated to facilitate the insulator mud blank 24 to be removed from the groove, thereby reducing manual operation of personnel and avoiding the insulator mud blank 24 from being stuck in the groove.

[0043] A combined sensor is arranged inside the plug 23, and the combined sensor includes a temperature sensor and a humidity sensor, so as to facilitate real-time detection of the temperature and humidity of the internal coating.

[0044] A suction pump is fixed at the bottom end of the support frame 1. The collection box 18, the suction pump and the material storage box 4 are connected in sequence through a discharge pipe 19. The suction pump can suck the glaze inside the collection box 18 into the material storage box 4 to save resources.
