Description

Technical Field

[0001] The invention relates to the technical field of insulator processing, and in particular to a suction cup glazing machine and a glazing method for insulator production. Background Art

[0002] An insulator is a device that can withstand voltage and mechanical stress and is installed between conductors of different potentials or between conductors and grounded components. There are many types of insulators, with different shapes and sizes ranging from a few centimeters to several meters. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting hardware. According to the different materials used for insulating parts, they can generally be divided into porcelain insulators, glass insulators and composite insulators. Among them, porcelain insulators are the most commonly used, and the electrical ceramics used in their insulating parts are baked from quartz, feldspar and clay as raw materials. During the production process, glaze water needs to be poured onto the insulator blank after blanking, and then fired and formed, so that the surface of the porcelain part is covered with a layer of porcelain glaze, so as to improve the mechanical strength of the porcelain insulator, prevent water infiltration, and increase the surface smoothness. At present, the glazing process of porcelain insulators is mostly semi-automatic, requiring a single manual loading and unloading, and it is impossible to achieve simultaneous glazing of large batches of blanks, which greatly affects production efficiency. Some automatic glazing machines partially solve the above problems by dipping glaze on an assembly line, but they can usually only be used for disc-type suspension porcelain insulators and shorter column insulators, and are not suitable for glazing large insulators.

The glaze pool is provided with a water inlet and a water return port, and the water inlet and the water return port are connected to the circulation system.

[0004] Furthermore, the column device includes a column, both sides of which are slidably connected to the lifting groove through an automatic rail A, a negative pressure chamber is opened inside the column, and the negative pressure chamber can be connected to a movable hose of the negative pressure pipeline through the flange on the top of the column.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The present invention will be further described below in conjunction with the accompanying drawings:

[0026] like Figures 1 to 6 As shown, a sucker glazing machine for insulator production includes a glaze pool 1, and a plurality of pairs of lifting grooves 101 are opened on the two longitudinal walls of the glaze pool 1 (as shown in the figure, three pairs in this embodiment), and an aisle plate 17 is set between the two longitudinal walls. The end of the aisle plate 17 is located between two adjacent lifting grooves 101 on the same side. The lifting groove 101 is slidably connected to the column device (so the column devices on the longitudinal walls on both sides are also paired), and the column device includes a column 2, and the two sides of the column 2 are slidably connected to the lifting groove 101 through an automatic rail A3, and a negative pressure cavity 201 is opened inside the column 2. A movable hose that can be connected to the negative pressure pipeline through the top flange of the column 2, a plurality of rows of bosses 202 are provided in the vertical direction along the opposite surface of the column 2 (as shown in the figure, there is only one row in this embodiment), the end face of the boss 202 is connected to the negative pressure chamber 201, the boss 202 is rotatably connected to the adsorption disk 4, the adsorption disk 4 is provided with a gear ring 401, the gear rings 401 of adjacent adsorption disks 4 are meshed, and a plurality of adsorption holes 402 are opened on the end face of the adsorption disk 4. When the negative pressure chamber 201 is connected to the negative pressure pipeline, the adsorption holes 402 will generate suction to make the insulator 19 fit to the end face of the adsorption disk 4. If the adsorption object is a small insulator 19, each adsorption disk 4 corresponds to one insulator 19 (that is, only one end of the small insulator 19 is adsorbed); if the adsorption object is a large column insulator 19, each pair of adsorption disks 4 corresponds to one insulator 19 (such as Figure 3 As shown, both ends of the large insulator 19 are adsorbed).

[0027] In this embodiment, the driving device is arranged behind the driving side column device, and the driving device is used to rotate the insulator adsorbed by the column device in the glaze water. The driving device includes a motor room 5 opened behind the driving side column device, the motor room 5 is connected to the lifting groove 101 through an axis hole 501, the motor 6 is slidably connected to the bottom of the motor room 5 through the automatic rail B7, and the output end of the motor 6 is inserted into the axis hole 501 and slidably connected to the axis hole 501; a shaft 403 (such as Figure 4 As shown), the shaft 403 is rotatably connected to the through hole on the back side of the column 2, and a coupling hole 404 is opened on the end face of the shaft 403. Under the push of the automatic rail B7, the output end of the motor 6 can slide out of the shaft hole 501 and be inserted into the coupling hole 404 to achieve a driving connection (through a matching spline), so that the motor 6 can drive the adsorption disk 4 to rotate, and drive the other adsorption disks 4 on the column 2 to rotate through the engagement between the gear rings 401.

[0028] From the above, it can be seen that the driving device can only directly drive the adsorption disk 4 on the driving side column 2 to rotate. When glazing a large column insulator 19, the adsorption disk 4 on the opposite side can be driven to rotate through the transmission of the insulator 19. Therefore, only one side of the paired column devices needs to be the driving side (this is the case in the attached figure); when glazing a small insulator, both sides need to be the driving side, that is, each column device is equipped with a driving device.

[0029] In this embodiment, the glaze pool 1 is provided with a water inlet 102 and a water return port 103, and the water inlet 102 and the water return port 103 are connected to the circulation system. The circulation system includes a circulation chamber 8 opened behind the horizontal wall on one side of the glaze pool 1, and the circulation chamber 8 has a liquid storage tank 9 and a filter 10 built in. The inlet end of the filter 10 is connected to the water return port 103 through an automatic valve A11, and the outlet end of the filter 10 is connected to the inlet end of the liquid storage tank 9 through a pump A12, and the outlet end of the liquid storage tank 9 is connected to a pump B13, and the pump B13 is connected to the water inlet 102 through an automatic valve B14; the glaze pool 1 is provided with a water level sensor 15, and the water level sensor 15 is electrically connected to the circulation system controller 16 to transmit water level data to it in real time. When the water level is lower than the set value, the circulation system controller 16 controls the pump B13 to inject the glaze water in the liquid storage tank 9 into the glaze pool 1; when the water level is too high or the glaze water needs to be filtered, the circulation system controller 16 controls the pump A12 to start, so that the glaze water in the glaze pool 1 is filtered by the filter 10 and then injected into the liquid storage tank 9 for storage.

[0030] In this embodiment, a loading vehicle 18 is provided, and the front and rear ends of the vehicle frames 1801 on both sides of the loading vehicle 18 are connected by a cross beam 1802. A universal wheel 1803 is provided at the bottom of the vehicle frame 1801. The vehicle frame 1801 includes a plurality of longitudinal beams 1804. A groove rail A is provided on the top surface of the longitudinal beams 1804. A plurality of supporting rods 1805 are provided between the longitudinal beams 1804 of corresponding heights on both sides. The height of the supporting rods 1805 corresponds to the suction plate 4 on the column 2 when it is raised (as shown in the figure, the four layers of supporting rods 1805 in this embodiment correspond to four pairs of suction plates 4 respectively). The quick-release heads A at both ends of the support rod 1805 are slidably connected to the groove rail A, and the top surface of the support rod 1805 is provided with a groove rail B, and the groove rail B is slidably connected to the quick-release head B at the bottom of the support block 1806, and the top of the support block 1806 can cooperate with the neck of the insulator 19. The number of support blocks 1806 on each support rod 1805 is determined according to the number of columns of the bosses 202 (or adsorption plates 4) on the column 2 (the column 2 in the attached figure has only one column of adsorption plates 4, and the adsorbed insulators 19 also have only one column, so each support rod 1805 only needs to be equipped with one support block 1806).

[0031] The present invention also provides a glazing method for insulator production, comprising the following steps:

[0032] Loading stage: Place the insulator 19 on the support block 1806 of the loading vehicle 18, and push the loading vehicle 18 to the top of the glaze pool 1. At this time, the corresponding column devices on both sides are located in the frame opening surrounded by the bottom of the loading vehicle 18 (such as Figure 6 As shown), the column 2 is raised by the automatic rail A3, and the position of the insulator 19 is adjusted by the sliding support block 1806, so that the insulators 19 of each layer on the loading vehicle 18 correspond to the adsorption plates 4 of different heights, and the movable hose of the negative pressure pipeline is connected to the top flange of the column 2, and the insulator 19 is pressed and fitted to the adsorption plate 4, and the support rod 1805 between the longitudinal beams 1804 is removed, and the column 2 with the insulator 19 is sunk into the glaze pool 1;

[0033] Glazing stage: after the column 2 drops to the lowest point, the coupling hole 404 and the shaft hole 501 are coaxial, and the automatic rail B7 drives the motor 6 to slide inward, and the output end of the motor 6 slides out of the shaft hole 501 and is connected to the coupling hole 404 through a spline engagement drive. Driven by the motor 6, the mutually meshed adsorption plates 4 on the driving side rotate together, and drive the insulator 19 adsorbed thereon to rotate, and the insulator 19 is glazed during the rotation process;

[0034] Reset stage: After the insulator 19 is glazed, the motor 6 stops rotating, the automatic rail B7 drives the motor 6 to slide outward, the output end of the motor 6 is disconnected from the coupling hole 404 and slides into the shaft hole 501, the automatic rail A3 raises the column 2 again, and the insulator 19 is raised and drained for a period of time;

[0035] Unloading stage: After the insulator 19 is drained, the support rod 1805 is reinstalled on the longitudinal beams 1804 of each layer of the loading cart 18, and the support block 1806 is slid to align it with the neck of the insulator 19. Then, the connection between the movable hose and the top flange of the column 2 is disconnected, so that the insulator 19 falls onto the support block 1806, and the column 2 is lowered back into the lifting slot 101. The loading cart 18 carrying the glazed insulator 19 is pushed to the baking process.

[0036] The present invention can glaze various types of insulators in batches, and is particularly suitable for large insulators. It is equipped with a special loading vehicle to conveniently and efficiently complete loading, unloading and subsequent drying work, and has a circulation system to circulate and filter glaze water and maintain the water level to ensure a stable glazing process.
