Description

Technical Field

[0001] This utility model relates to the field of oil channel support curtain production technology, and in particular to an oil channel support curtain pressing device. Background Technology

[0002] In the transformer manufacturing process, insulating paperboard and support bars together form cooling oil channels, and their bonding accuracy directly affects insulation performance and heat dissipation efficiency. With the growth of global electricity demand and the continuous expansion of transformer production capacity, the insulating paperboard-support bar bonding process has become a key bottleneck restricting the delivery cycle of the entire unit.

[0003] Existing methods for attaching support strips typically involve pausing the winding of the insulating cardboard and then manually placing individual support strips onto the cardboard for pressing. Some production lines pre-stack the support strips in a hopper and then press them together one by one using intermittent pushers. Regardless of whether manual intervention or pusher feeding is used, there is a possibility that the support strips may tilt.

[0004] Manual placement requires measuring the distance between the two ends before placement. However, when the support strip falls onto the insulating cardboard, the material is prone to tilting, which not only affects the bonding quality but also the production schedule. Accumulated errors in the bonding position require secondary trimming or rework of the entire roll of product, which not only affects the production rhythm but also increases the scrap rate. Utility Model Content

[0005] The purpose of this invention is to propose an oil channel support strip pressing device to solve the problems of easy tilting and large bonding position error of the support strips on the insulating cardboard in the prior art.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows: An oil channel support strip pressing device includes a conveyor belt with a pressure plate mounted horizontally and vertically across its upper part. The conveyor belt is used to transport insulating paperboard, and the pressure plate presses the support strips onto the insulating paperboard. There are two sets of winding machines, located at both ends of the conveyor belt, which drive the winding and unwinding of the insulating paperboard. A conveying mechanism is located at one end of the conveyor belt, near the winding machine that outputs the insulating paperboard, and is used to place the support strips onto the insulating paperboard.

[0007] By adopting the above technical solution, the insulating paperboard is continuously unwound and wound between two sets of winding machines, the conveyor belt operates synchronously, the conveying mechanism places the support strip directly on the surface of the paperboard at the output end, and the pressure plate then descends to complete the pressing, realizing continuous operation and avoiding the cumulative error caused by the stop.

[0008] Furthermore, a support frame is fitted onto the conveyor belt, and the pressure plate moves up and down within the support frame. A hydraulic cylinder is installed on the support frame, and the driving end of the hydraulic cylinder passes through the support frame and is connected to the pressure plate to drive the pressure plate to move up and down.

[0009] By adopting the above technical solution, the hydraulic cylinder and the support frame form a closed force system, the lifting stroke of the pressure plate is stable, the pressing force is uniform, and the fitting deviation caused by uneven force is reduced.

[0010] Furthermore, the support frame includes a base plate fixedly disposed at the bottom of the conveyor belt, support columns located on both sides of the conveyor belt and fixedly disposed on the base plate, and a top plate fixedly disposed on the top of the support columns, wherein the hydraulic cylinder is mounted on the top plate.

[0011] By adopting the above technical solution, the base plate, support column and top plate form a rigid gantry structure with high overall strength and small frame deformation when the pressure plate moves, which further ensures the pressing and positioning accuracy.

[0012] Furthermore, a through hole is provided on the top plate, and an auxiliary rod is installed in the through hole. The lower end of the auxiliary rod is fixedly connected to the pressure plate, and the auxiliary rod is located on both sides of the hydraulic cylinder.

[0013] By adopting the above technical solution, the auxiliary rod guides the pressure plate on both sides, suppressing possible swaying during the lifting process and preventing the pressure plate from tilting and causing the support bar to shift.

[0014] Furthermore, the conveying mechanism includes two columns disposed at one end of the conveyor belt, a feeding disc rotatably disposed on the columns, and a groove formed on the side of the feeding disc, the groove being used to accommodate the support bar.

[0015] By adopting the above technical solution, the support bar is embedded in the groove and rotates with the feeding plate. The landing position is uniquely determined by the angle of the groove, eliminating the error of manual placement.

[0016] Furthermore, a roller is rotatably arranged between the two columns, the feeding disc is fixed on the roller, and a motor for driving the roller to rotate is provided on one side of the column.

[0017] By adopting the above technical solution, the motor synchronously drives the feeding disc through the roller shaft, the rotation angle is controllable, and the support bar rhythm is matched with the conveyor belt speed, avoiding feeding delay or advance.

[0018] Furthermore, the feeding tray includes multiple sector-shaped discs and a support disc fixed on the roller shaft. The sector-shaped discs are fixed on the support discs by screws, and the grooves are formed on both sides of the arc-shaped surface of the sector-shaped discs.

[0019] By adopting the above technical solution, the sector disc can be replaced individually, and the entire disc does not need to be replaced after the groove is worn, thus maintaining long-term material feeding accuracy.

[0020] Furthermore, the plurality of the fan-shaped disks are evenly distributed along the circumference of the support disk to form a circular feeding disk.

[0021] By adopting the above technical solution, the circumferential distribution ensures the balance of the feeding disc's mass and smooth rotation, guaranteeing that the support bar falls at the same angle each time, further reducing positional deviation.

[0022] Compared with the prior art, the present invention has the following beneficial effects: The oil channel support strip pressing device described in this utility model eliminates the cumulative error caused by pauses through the integrated design of continuous unwinding, feeding, and pressing, resulting in good consistency in the bonding position. The rigid system formed by the support frame and hydraulic cylinder ensures stable lifting and lowering of the pressure plate, uniform pressing force, and reduces bonding defects. The double-sided auxiliary rod guides suppress pressure plate swaying and prevent support strip displacement during the pressing process. The replaceable fan-shaped disc structure facilitates maintenance, maintains feeding accuracy over a long period, and reduces maintenance costs. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] This embodiment relates to an oil channel support curtain pressing device, the overall structure of which is as follows: Figure 1 and Figure 2 As shown, it includes a conveyor belt 1, a winding machine 2, and a conveying mechanism 3.

[0031] The conveyor belt 1 is equipped with a pressure plate 4, which is used to transport insulating paperboard. The pressure plate 4 is lifted and lowered on the conveyor belt 1 to press the support strip onto the insulating paperboard. There are two sets of winding machines 2, located at both ends of the conveyor belt 1, which are used to wind up and unwind the insulating paperboard. The conveying mechanism 3 is located at one end of the conveyor belt 1 and on the side of the winding machine 2 that outputs the insulating paperboard. The conveying mechanism 3 is used to place the support strip onto the insulating paperboard.

[0032] It is worth mentioning that the pressure plate 4 is arranged along the width of the conveyor belt 1 and can be raised and lowered at the top of the conveyor belt 1. One set of winding machines 2 can output insulating paperboard, and another set of winding machines 2 can wind up the pressed insulating paperboard and support strips. The insulating paperboard passes from the output winding machine 2 through the conveyor belt 1, and then the conveying mechanism 3 places the support strips on the insulating paperboard on the conveyor belt 1. When the insulating paperboard and support strips move to the lower part of the pressure plate 4, the pressure plate 4 descends and presses the support strips onto the insulating paperboard. This setting realizes automatic pressing of the support strips, which greatly improves work efficiency compared to manual pasting of support strips.

[0033] Based on the above overall introduction, this embodiment presents an exemplary structure of the oil channel support curtain pressing device, such as... Figure 3As shown, a base plate 5 is fixedly installed at the bottom of the conveyor belt 1. Support columns 6 are installed on both sides of the conveyor belt 1 on the base plate 5. A top plate 7 is installed on the top of the support columns 6. A hydraulic cylinder 8 is installed on the top plate 7. The drive shaft of the hydraulic cylinder 8 passes through the top plate 7 and is fixedly connected to the pressure plate 4.

[0034] It should be noted that the base plate 5, support column 6 and top plate 7 form a square support frame. The frame can fix the hydraulic cylinder 8 to the top of the conveyor belt 1, which is convenient for controlling the lifting and lowering of the pressure plate 4, and will not affect the operation of the conveyor belt 1. The base plate 5 is fixedly installed at the bottom of the conveyor belt 1, and the column 301 is used to support the top plate 7 to ensure that the top plate 7 remains horizontal. The pressure plate 4 moves up and down between the top plate 7 and the conveyor belt 1. This arrangement ensures that the pressure plate 4 can stick the support strip to the insulating cardboard.

[0035] As a preferred option, it remains as follows Figure 3 As shown, in this embodiment, a through hole 9 is provided on the top plate 7, and an auxiliary pressure plate 4 and a lifting auxiliary rod 10 are installed in the through hole 9. The auxiliary rod 10 and the pressure plate 4 are fixed with screws. Specifically, the auxiliary rod 10 is located on both sides of the hydraulic cylinder 8. When the hydraulic cylinder 8 drives the pressure plate 4 to rise and fall, the auxiliary rod 10 rises and falls accordingly. This arrangement ensures that the pressure plate 4 will not deviate from its direction and avoids deviation from its position when the support strip is pressed.

[0036] As a preferred implementation method, such as Figure 4 As shown, in this embodiment, the conveying mechanism 3 includes two columns 301 fixedly installed at one end of the conveyor belt 1, a feeding disc rotatably installed on the columns 301, and a groove 303 opened on the side of the feeding disc for placing the support bar. The axis of the feeding disc is arranged perpendicular to the axis of the columns 301.

[0037] It should be noted that the feeding disc is rotated on the top of the column 301. The support bar is placed from the top of the feeding disc onto the groove 303 and then rotates towards the side of the conveyor belt 1. When the groove 303 rotates to face downwards, the support bar automatically falls from the groove 303 onto the insulating cardboard on the conveyor belt 1. After this arrangement is completed, the column 301 is located on one side of the output winding machine 2, ensuring that after the output support bar of the conveyor mechanism 3 is placed onto the conveyor belt 1, the support bar falls directly onto the insulating cardboard, reducing the need for manual placement of the support bar.

[0038] As a preferred option, such as Figure 5As shown, in this embodiment, a roller 304 is rotatably arranged between two columns 301, and a feeding disc is fixedly mounted on the roller 304. A motor 305 that drives the roller 304 to rotate is fixedly mounted on one side of each column 301. Specifically, the roller 304 passes through the top of the two columns 301, and the motor 305 is fixedly mounted on one of the columns 301. The motor 305 drives the roller 304 to rotate, and two feeding discs are arranged opposite each other on the roller 304. The two sides of the support bar are placed on the two feeding discs respectively to ensure the stability of the support bar and avoid deviation, thereby improving the adhesion and pressing quality.

[0039] As a preferred option, it remains as follows Figure 5 As shown, in this embodiment, the feeding tray consists of multiple sector-shaped disks 302. A support disk 306 for mounting the sector-shaped disks 302 is fixedly mounted on the roller shaft 304. The multiple sector-shaped disks 302 are arranged circumferentially on the support disk 306. Specifically, the sector-shaped disks 302 are fixed to the support disk 306 with screws. Grooves 303 are formed on both sides of the arc-shaped surface of the sector-shaped disks 302. The multiple sector-shaped disks 302 are evenly arranged on the support disk 306 to form a complete circular feeding tray. This arrangement facilitates assembly and replacement, and improves adaptability.

[0040] The winding machine 2 is a common winding device in the prior art, generally composed of a winding reel, motor 305, support frame and other components. It only needs to complete the winding of insulating paperboard, so it will not be described in detail here. When sticking the support strips onto the insulating paperboard, adhesive needs to be applied. The support strips can be placed in front of the conveying mechanism 3 to apply the adhesive. The equipment for applying adhesive to the support strips adopts the common glue application equipment in the prior art, generally composed of a straight module and a brush. It only needs to complete the application of glue to the support strips, so it will not be described in detail here.

[0041] The oil channel support strip pressing device in this embodiment eliminates the cumulative error caused by pauses through the integrated design of continuous unwinding, feeding, and pressing, resulting in good consistency in the bonding position. The rigid system formed by the support frame and the hydraulic cylinder 8 ensures stable lifting and lowering of the pressure plate 4, uniform pressing force, and reduces bonding defects. The double-sided auxiliary rods 10 guide and suppress the swaying of the pressure plate 4, preventing the support strip from shifting during the pressing process. The replaceable fan-shaped disk 302 structure facilitates maintenance, maintains feeding accuracy over a long period, and reduces maintenance costs.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
