Description

Technical Field

[0001] This utility model relates to the field of adhesive coating technology for accessories, specifically, to an adhesive coating machine for the production of transformer insulation accessories. Background Technology

[0002] As a core piece of equipment in the power system, the safe and stable operation of transformers highly depends on the reliability of their insulation system, and the adhesive coating process for insulation components is a crucial link in ensuring the effectiveness of this system. During operation, transformers not only endure high-voltage electric fields but also face continuous temperature rises, mechanical vibrations, and the corrosive effects of external moisture and dust. Gaps or loose connections in insulation components can easily become weak points in the electric field distortion, leading to partial discharge or even insulation breakdown, directly threatening equipment safety. Adhesive coating precisely fills the gaps between components, forming a continuous, sealed insulation layer. This not only blocks the intrusion paths of moisture and impurities, preventing insulation materials from aging and failing due to moisture, but also enhances the mechanical fixing strength between components, reducing loosening and wear caused by vibration. Furthermore, the temperature-resistant and insulating properties of the adhesive layer further optimize the electric field distribution, slowing down the aging rate of the insulation, thus building a solid insulation defense for the long-term stable operation of the transformer.

[0003] In existing technologies, some glue applicators are insufficient for applying glue to uneven surfaces of parts. This is most typical for the curved sides of cylindrical parts. Unlike for flat surfaces, glue applicators cannot fix the parts, open the glue tank outlet, and control the glue tank to move across the part's surface to obtain a glue layer of roughly the same thickness. If the curved side is divided into many strips along the axial direction and glued to each strip sequentially, it would be too time-consuming.

[0004] Therefore, this utility model provides a stable welding device for mold manufacturing to solve the above-mentioned problems. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a glue coating machine for the production of transformer insulation accessories. It solves the technical problem in the prior art that, for uneven coating surfaces, it is impossible to fix the accessories in the same way as for flat surfaces. The glue tank outlet is opened and the glue tank is controlled to move horizontally on the surface of the accessories to obtain a glue layer of approximately the same thickness.

[0006] According to one aspect, at least one embodiment of the present invention provides a gluing machine for the production of transformer insulation components, comprising: a bottom platform, an upper platform disposed at the top of the bottom platform, and a gluing mechanism disposed on the side of the upper platform. A transfer mechanism is disposed above the upper platform. The transfer mechanism includes a sliding box disposed on the gluing mechanism, a plurality of threaded tubes threadedly connected to the bottom of the sliding box, and a gluing component rotatably inserted into the threaded tubes. The gluing component is configured as a cylindrical tube, with an open top and a closed bottom. The fitting surface is designed to mate with the curved side of the part to be glued. A glue application port that is laterally covered by the curved surface is opened on the fitting surface. A glue inlet is opened on the top surface of the sliding box corresponding to the position of the glued part. First, a glued part that mates with the surface of the part to be glued is selected. A threaded tube is rotatably sleeved on the side wall of the glued part. The threaded tube is threaded onto the sliding box, thus installing the glued part. Then, the glued part is rotated to the appropriate position. The glue is transferred from the glue application mechanism to the transfer mechanism. The glue application port is a narrow opening that is laterally covered with the fitting surface, which can evenly apply the glue to the surface of the part that contacts the fitting surface in one go.

[0007] For example, in at least one embodiment of the present invention, a glue-applying machine for producing transformer insulation components further includes, as a preferred technical solution of the present invention, a glue-applying mechanism comprising a support frame fixedly disposed on the bottom platform corresponding to the side of the upper platform, a sliding member that moves longitudinally within the support frame, and a threaded rod threadedly connected to the sliding member. One end of the threaded rod passes through the sliding member and is rotatably connected to a connecting member. A glue storage tank is longitudinally disposed on the connecting member, and an outlet is disposed at the bottom of the glue storage tank. When the threaded rod is rotated, the threaded rod is threadedly connected to the sliding member, so the threaded rod moves on the sliding member, driving the connecting member, which in turn drives the glue storage tank to move, moving the glue storage tank above the set glue-applying component. The sliding member moves downward, causing one end of the glue storage tank to pass through the glue-applying port and contact the glue-applying component.

[0008] For example, in at least one embodiment of the present invention, a glue-applying machine for producing transformer insulation accessories is provided, which further includes: a hydraulic cylinder fixedly installed at the top of the bottom platform inside the support frame; a hydraulic rod fixedly installed at the output end of the hydraulic cylinder; and the end of the hydraulic rod away from the hydraulic cylinder fixedly installed on the sliding member. The hydraulic cylinder is used to drive the sliding member to move up and down.

[0009] For example, in at least one embodiment of the present invention, a glue-applying machine for producing transformer insulation accessories is provided, which further includes: a plurality of positioning rods fixedly provided on the side of the sliding member near the connecting member, the positioning rods being slidably inserted into the connecting member, the positioning rods enabling the connecting member to move stably, ensuring that the angle of the connecting member remains consistent with that of the sliding member, and preventing the glue storage tank from rotating.

[0010] For example, in at least one embodiment of the present invention, a glue coating machine for producing transformer insulation accessories is provided, which further includes: a switching mechanism is provided in the glue storage tank near the outlet end. The switching mechanism includes a cross plate A fixed on the inner wall of the glue storage tank, an elastic telescopic member A fixed on the cross plate A near the outlet side, and a blocking plate fixed on the elastic telescopic member A near the outlet end. Pushing the blocking plate inward will open the glue storage tank, and conversely, the glue storage tank will be closed by the action of the blocking plate.

[0011] For example, in at least one embodiment of the present invention, a glue applicator for producing transformer insulation accessories is provided, which further includes: the switching mechanism further includes a cross plate B fixedly disposed on the inner wall of the glue applicator and an insert rod fixedly disposed on the side of the cross plate B near the glue storage tank, the insert rod being used to push open the blocking plate.

[0012] For example, in at least one embodiment of the present invention, a glue-applying machine for the production of transformer insulation accessories is provided, which further includes: a conveying mechanism fixedly arranged on the bottom platform at a position corresponding to the upper platform above the bottom platform for batch glue application.

[0013] For example, in at least one embodiment of the present invention, a glue-applying machine for producing transformer insulation accessories is provided, which further includes: the conveying mechanism includes a conveyor belt, and the conveyor belt is provided with a limiting member for limiting the accessories to be glued.

[0014] For example, in at least one embodiment of the present invention, a glue-applying machine for producing transformer insulation accessories further includes: the limiting member is positioned corresponding to the glue-applying part.

[0015] For example, in at least one embodiment of the present invention, a glue-applying machine for producing transformer insulation accessories is provided, which further includes: elastic telescopic members B are fixedly provided at both ends of the bottom of the sliding box corresponding to the positions of the side plates of the conveying mechanism. The two ends of the elastic telescopic members B are respectively fixedly provided on the sliding box and the side plates of the conveying mechanism. The elastic telescopic members B are used to support the sliding box so that the conveying mechanism can operate smoothly.

[0016] The beneficial effects of the embodiments of this utility model are as follows: This invention features an adhesive applicator with a threaded tube rotatably fitted onto its side wall. The threaded tube is then threaded onto a sliding box, thus installing the adhesive applicator. After rotating the applicator to the appropriate position, the adhesive moves within the applicator, quickly filling it and being squeezed out from the applicator nozzle at the bottom. The nozzle is a narrow, elongated opening that horizontally covers the mating surfaces, allowing for uniform application of adhesive to the surfaces of the parts in contact with the mating surfaces in one go. This design is characterized by high quality and efficiency.

[0017] This invention features a threaded rod. When the threaded rod is rotated, it is threadedly connected to a sliding component. As the threaded rod moves on the sliding component, it drives a connecting component, which in turn drives the glue storage tank to move above the pre-set glue application component. At this point, a hydraulic cylinder is driven, which in turn drives a hydraulic rod to move downwards. This causes one end of the glue storage tank's upper outlet to pass through the glue application port and contact the glue application component, thus connecting the glue application mechanism with the transfer mechanism.

[0018] This invention features a push rod on the glue applicator that presses against a blocking plate inside the glue storage tank. The blocking plate compresses and moves the elastic telescopic component A. Under the action of the glue storage tank's own driving device, the glue in the storage tank flows towards the outlet and then moves into the glue applicator below. The glue applicator and the glue storage tank adhere and press against each other at the junction, and a rubber ring or other seal can be used to prevent glue leakage, thus completing the transfer of glue from the glue applicator to the transfer mechanism.

[0027] like Figure 1 Figure 6The diagram illustrates a gluing machine for producing transformer insulation components according to an embodiment of the present invention. It includes a bottom platform 1, an upper platform 2 positioned at the top of the bottom platform 1, and a gluing mechanism 3 positioned on the side of the upper platform 2. A transfer mechanism 4 is positioned above the upper platform 2. The transfer mechanism 4 includes a sliding box 41 mounted on the gluing mechanism 3, several threaded tubes 42 threaded to the bottom of the sliding box 41, and a gluing component 43 rotatably inserted into the threaded tubes 42. The gluing component 43 is cylindrical, with an open top and an arc-shaped bottom end that meets the component to be glued. The mating surface 431 is fitted with the side of the part, and the mating surface 431 is provided with a horizontally covering glue application port 432. The top surface of the sliding box 41 is provided with a glue application port 411 corresponding to the position of the glue application part 43. First, a glue application part 43 that fits the surface of the part to be glued is selected. A threaded tube 42 is rotatably sleeved on the side wall of the glue application part 43. The threaded tube 42 is threaded onto the sliding box 41, that is, the glue application part 43 is installed. Then, the glue application part 43 is rotated to a suitable position. The glue is transferred from the glue application mechanism 3 to the transfer mechanism 4. The glue application port 432 is a narrow opening that is horizontally covered with the mating surface 431, which can evenly apply the glue to the surface of the part that contacts the mating surface 431 in one go.

[0028] Furthermore, the gluing mechanism 3 includes a support frame 31 fixedly mounted on the bottom platform 1 corresponding to the side of the upper platform 2, a sliding member 32 that moves longitudinally within the support frame 31, and a threaded rod 33 threadedly connected to the sliding member 32. One end of the threaded rod 33 passes through the sliding member 32 and is rotatably connected to a connector 34. A glue storage tank 35 is longitudinally mounted on the connector 34, and an outlet 351 is provided at the bottom of the glue storage tank 35. When the threaded rod 33 is rotated, it is threadedly connected to the sliding member 32. Therefore, the threaded rod 33 moves on the sliding member 32, driving the connector 34. The connector 34 drives the glue storage tank 35 to move, moving the glue storage tank 35 above the set glue applicator 43. The sliding member 32 moves downward, causing one end of the outlet 351 on the glue storage tank 35 to pass through the glue application port 411 and contact the glue applicator 43.

[0029] Furthermore, a hydraulic cylinder 36 is fixedly installed at the top of the bottom platform 1 inside the support frame 31, and a hydraulic rod 37 is fixedly installed at the output end of the hydraulic cylinder 36. The end of the hydraulic rod 37 away from the hydraulic cylinder 36 is fixedly installed on the sliding member 32. The hydraulic cylinder 36 is used to drive the sliding member 32 to move up and down.

[0030] Among them, a plurality of positioning rods 38 are fixedly provided on the side of the sliding member 32 near the connecting member 34. The positioning rods 38 are slidably inserted into the connecting member 34. The positioning rods 38 can make the connecting member 34 move stably, so that the angle of the connecting member 34 is always consistent with that of the sliding member 32, and prevent the glue storage tank 35 from rotating.

[0031] Specifically, a switching mechanism 5 is provided inside the glue storage tank 35 near the outlet 351. The switching mechanism 5 includes a cross plate A51 fixed on the inner wall of the glue storage tank 35, an elastic telescopic member A52 fixed on the cross plate A51 near the outlet 351, and a blocking plate 53 fixed on the elastic telescopic member A52 near the outlet 351. Pushing the blocking plate 53 inward will open the glue storage tank 35, and conversely, the glue storage tank 35 will be closed by the action of the blocking plate 53.

[0032] It is worth noting that the switching mechanism 5 also includes a cross plate B54 fixedly disposed on the inner wall of the adhesive coating component 43 and a plug rod 55 fixedly disposed on the side of the cross plate B54 near the adhesive storage tank 35. The plug rod 55 is used to push open the blocking plate 53.

[0033] It should be noted that a conveying mechanism 6 is fixedly installed on the bottom platform 1 at a position above the upper platform 2, for batch gluing.

[0034] Furthermore, the conveying mechanism 6 includes a conveyor belt 61, on which a limiting member 62 for restricting the parts to be coated with glue is provided.

[0035] Furthermore, the limiting member 62 is positioned corresponding to the adhesive coating member 43.

[0036] Specifically, elastic telescopic members B63 are fixedly installed at both ends of the bottom of the sliding box 41 corresponding to the positions of the side plates of the conveying mechanism 6. The two ends of the elastic telescopic members B63 are respectively fixedly installed on the sliding box 41 and the side plates of the conveying mechanism 6. The elastic telescopic members B63 are used to support the sliding box 41 and keep the conveying mechanism 6 running smoothly.

[0037] Working principle and usage process of this utility model: When the glue applicator is working, firstly, a glue applicator part 43 that fits the surface of the part to be glued is selected. A threaded tube 42 is rotatably sleeved on the side wall of the glue applicator part 43. The threaded tube 42 is threaded onto the sliding box 41, thus installing the glue applicator part 43. Then, the glue applicator part 43 is rotated to the appropriate position, and the threaded rod 33 is rotated. The threaded rod 33 is threadedly connected to the sliding part 32, so the threaded rod 33 moves on the sliding part 32, driving the connecting part 34. The connecting part 34 drives the glue storage tank 35 to move, moving the glue storage tank 35 to the set glue applicator position. Above component 43, hydraulic cylinder 36 is driven. Hydraulic cylinder 36 can be an SC50-100 model, powered by an external hydraulic pump. Hydraulic cylinder 36 drives hydraulic rod 37 downwards. One end of outlet 351 on the glue tank 35 passes through the glue inlet 411 and contacts the glue applicator 43. The insert rod 55 on the glue applicator 43 abuts against the blocking plate 53 inside the glue tank 35. The blocking plate 53 compresses the elastic telescopic member A52, causing it to move. Under the action of the built-in drive device of the glue tank 35, the glue inside the glue tank 35 flows towards outlet 35. 1. The adhesive then moves into the lower coating part 43. The coating part 43 and the glue storage tank 35 are pressed together and sealed with rubber rings to prevent glue leakage. The glue continues to move inside the coating part 43, quickly filling it, and is squeezed out from the coating port 432 below the coating part 43. The coating port 432 is a narrow opening that is horizontally covered with mating surfaces 431, which can evenly apply the glue to the surface of the accessory that contacts the mating surfaces 431 in one go. It has the characteristics of high quality and high efficiency. The positioning rod 38 can make the connector 34 stable. The fixed movement ensures that the angle of the connecting part 34 remains consistent with that of the sliding part 32, preventing the glue storage tank 35 from rotating. The elastic coefficient of the elastic telescopic part A52 is greater than that of the elastic telescopic part B63. Therefore, when the insertion rod 55 contacts the blocking plate 53 in the glue applicator 43, the elastic telescopic part B63 contracts first, bringing the mating surface 431 close to the surface of the accessory. The glue then flows out from the glue applicator 43, preventing premature glue outflow and failure to apply it to the accessory. Rotating the threaded tube 42 can adjust the distance between the glue applicator 43 and the accessory. When applying glue to a small number of accessories, the accessories are placed directly on the upper platform 2, with one end of the elastic telescopic part B63 set on the upper platform 2. When there are a large number of accessories to be sprayed, the accessories can be placed on the dedicated limiting part 62, and the conveying mechanism 6 can be used for batch glue application.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
