[0022] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] like Figure 1-4 As shown, an automated porcelain insulator drying equipment includes a drying box 1, a plurality of movable support plates 3 distributed sequentially from top to bottom and horizontally slidably connected relative to the drying box 1, a plurality of clamping assemblies provided on top of the movable support plates 3, a cover frame 6 provided above the movable support plates 3 and vertically slidably connected to the drying box 1, a lifting assembly for driving the cover frame 6 to rise and fall, and a plurality of partition plates 7 provided inside the cover frame 6, wherein the cover frame 6 and the partition plates 7 are both provided with heaters 8, and the partition plates 7 partition the internal space of the cover frame 6 into a plurality of partition heating chambers, and a group of clamping assemblies corresponds to the bottom of each partition heating chamber;

[0024] When the cover frame 6 descends to contact the upper end surface of the movable support plate 3, each set of clamping assemblies is located inside a partitioned heating cavity, and each set of clamping assemblies can clamp and fix a porcelain insulator, that is, each porcelain insulator is located inside a partitioned heating cavity, then the cover frame 6 and the heater 8 on the partition plate 7 can heat and dry the porcelain insulator inside this partitioned heating cavity;

[0025] A cavity 31 is defined inside the movable support plate 3 , a hot air assembly is connected to the cavity 31 , and a plurality of air holes 34 are defined on the top of the cavity 31 . The air outlet directions of the air holes 34 are directed toward different positions of the porcelain insulator.

[0026] It should be noted that, in this embodiment, the porcelain insulator in the prior art includes an insulator body and a plurality of umbrella portions integrally formed on the insulator body;

[0027] Furthermore, the air outlet direction of the air flow hole 34 is toward the inner and outer wall surfaces of the umbrella part of the porcelain insulator, the connection position between the umbrella part of the porcelain insulator and the main body of the porcelain insulator, and the outer wall surface of the main body of the porcelain insulator. By combining the hot air directional conveying drying and the heating and drying by the heater 8, the occurrence of drying dead corners can be reduced or avoided, and the function of drying the porcelain insulator can be better achieved.

[0028] Preferably, the clamping assembly includes two clamping seats 4 symmetrically arranged on the movable support plate 3, two pressure plates 5 horizontally slidably connected to the two clamping seats 4, and a fixing piece for fixing the pressure plates 5 is provided on the clamping seat 4.

[0029] When in use, the porcelain insulator is placed between the two pressing plates 5 , and then the positions of the pressing plates 5 relative to the clamping seat 4 are adjusted so that the two pressing plates 5 are clamped at both ends of the porcelain insulator.

[0030] It should be noted that the lifting assembly is a conventional technology, including but not limited to the following methods:

[0031] The lifting assembly includes at least two screw rods 9 rotatably connected to the drying box body 1, a servo motor 11 provided on the servo motor 11 and connected to one of the screw rods 9, and a plurality of synchronizers 12 for driving all the screw rods 9 to rotate synchronously. Each of the cover frames 6 is provided with a nut seat 10 corresponding to the number of screw rods 9. The nut seat 10 is connected to the screw rod 9 through a ball nut pair. This implementation method is a conventional technology and will not be repeated here.

[0032] It should be noted that, in this embodiment, the synchronizer 12 is composed of two synchronizer wheels and a synchronizer belt disposed between the two synchronizer wheels;

[0033] In this embodiment, there are two screw rods 9 , one synchronizer 12 , and two synchronizer wheels are respectively provided on the two screw rods 9 .

[0034] When it is necessary to drive the cover frame 6 up or down, the servo motor 11 is started to drive the synchronous member 12 to transmit, and the transmission of the synchronous member 12 drives all the screw rods 9 to rotate. The rotation of the screw rods 9 causes the nut seat 10 and the cover frame 6 to move up or down along the screw rods 9.

[0035] Preferably, the side wall of the drying box body 1 is provided with a fixed seat 2 corresponding to the number of movable support plates 3, and the movable support plate 3 is horizontally slidably connected to the fixed seat 2 through a slider 1 and a slide groove 1, and the screw rod 9 passes through the fixed seat 2 and is rotationally connected to the fixed seat 2.

[0036] It should be noted that, in this embodiment, the cover frame 6 is vertically slidably connected to the drying box body 1 via a second slider and a second slide groove.

[0037] Preferably, the hot air assembly includes a hot air blower 13 provided on one side of the drying box 1, and a plurality of delivery branches 14 connected to the output end of the hot air blower 13. The delivery branches 14 extend into the interior of the drying box 1 and correspond one-to-one with the movable support plates 3. Each of the delivery branches 14 is provided with a switch valve. When the switch valve on the corresponding delivery branch 14 is opened, the delivery branch 14 can deliver hot air.

[0038] The movable support plate 3 also includes a connecting hole 32 opened at the rear end of the cavity 31 and a sealing gasket 33 provided on the inner wall of the connecting hole 32. The output end of the delivery branch pipe 14 extends into the interior of the cavity 31 and the outer wall of the delivery branch pipe 14 fits with the sealing gasket 33, which plays a certain sealing role.

[0039] When drying the porcelain insulator, the hot air blower 13 can generate a hot air flow, which is transported to the inside of the cavity 31 along the delivery branch pipe 14, and then blown toward the porcelain insulator through the air flow hole 34. At the same time, the heater 8 is used to heat and dry the periphery of the porcelain insulator, thereby achieving a better drying effect.

[0040] Preferably, the front end of the drying box body 1 is hinged with a sealed door 101, which is easy to open, and convenient for taking and placing the movable support plate 3 and clamping the porcelain insulator fixed on the top of the movable support plate 3. The front end of the sealed door 101 and the front end of each movable support plate 3 are provided with handles, which are convenient for staff to hold.

[0041] When in use, open the sealing door 101, make the servo motor 11 work to drive the synchronous member 12 to transmit, and then drive all the screw rods 9 to rotate, so that the cover frame 6 moves up. When the cover frame 6 does not block the movable support plate 3 and the parts or objects on the top of the movable support plate 3, the movable support plate 3 is extracted from the inside of the drying box 1, and the porcelain insulator is clamped and fixed by the clamping assembly on the top of the movable support plate 3, and then the movable support plate 3 is placed back into the drying box 1. At this time, the conveying branch pipe 14 is inserted into the connecting hole 32, and the servo motor 11 is worked again to drive the synchronous member 12 to transmit, and then drive all the screw rods 9 to rotate, so that the cover frame 6 is lowered. When the cover frame 6 is in contact with the upper end surface of the movable support plate 3, and the servo motor 11 is turned off. At this time, the porcelain insulator is located inside the partition heating chamber, and the heater 8 and the hot air blower 13 are operated. The operation of the heater 8 can heat and dry the entire porcelain insulator located inside the partition heating chamber, and the hot air flow generated by the operation of the hot air blower 13 is transported to the inside of the cavity 31 through the delivery branch pipe 14, and then output toward the porcelain insulator through the air flow hole 34, which can play a role in heating and drying. By combining the hot air delivery and drying toward the porcelain insulator and the heating and drying by the heater 8, the occurrence of drying dead corners can be reduced or avoided, and the effect of drying the porcelain insulator can be better achieved.

[0042] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
