Description

Technical Field

[0001] This utility model belongs to the field of power transformer component manufacturing, specifically relating to a cardboard tube processing equipment for the production of power transformer coils. Background Technology

[0002] Transformer coils are usually supported and fixed by cardboard tubes. In order to ensure that the size and quality of the coils meet the requirements, the height of the cardboard tubes is also very important.

[0003] Large coils typically use cardboard tubes with a diameter of over 1 meter and a height that can reach several meters. The height of the cardboard tube is generally slightly greater than the designed coil height. When winding the coil, one end of the cardboard tube needs to be sawn to the designed coil height. Currently, there is no mechanized equipment for sawing and chamfering cardboard tubes. In the coil production process, the height line for sawing is usually drawn manually on the cardboard tube according to the designed height dimensions on the coil drawing, plus a margin. A handheld circular saw is used to cut along the height line, followed by fine-tuning with an electric planer to the height required by the drawing. A handheld chamfering machine is then used to chamfer the inner and outer sides of the planed end of the cardboard tube according to the drawing, and it is sanded smooth. Finally, a vacuum cleaner is used to clean up the dust generated during sawing and chamfering. This method is time-consuming, labor-intensive, and subject to certain human error.

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0027] This utility model embodiment enables one person to perform sawing and rounding operations on the cardboard tube 14 by reasonably arranging the sawing and rounding processing mechanisms of the cardboard tube 14 and the rotation power mechanism of the cardboard tube 14. Example 1

[0028] like Figure 1 , Figure 2As shown, the cardboard tube processing equipment includes a fixed rubber roller 1 and two movable rubber rollers 2 arranged horizontally in the same direction. The two movable rubber rollers 2 are located on the left and right sides of the fixed rubber roller 1, respectively. The two movable rubber rollers 2 are at the same height, and the upper horizontal cross-section of the fixed rubber roller 1 is lower than the upper horizontal cross-section of the movable rubber roller 2. The rubber roller drive platform 3 is installed at the rear end of the processing equipment. The two ends of the fixed rubber roller 1 are rotatably mounted on the rubber roller drive platform 3 and the front fixed rubber roller seat 7, respectively. The two ends of the movable rubber roller 2 are rotatably mounted on the rubber roller drive platform 3 and the front movable rubber roller seat 4, respectively. The front movable rubber roller seat 4 is movably mounted on the front lead screw mechanism 5. Two pairs of limit frames 6 are symmetrically installed on the outside of the two movable rubber rollers 2. The processing mechanism 8 is installed on the front side of the front lead screw mechanism 5. The electrical box 9 is installed on the left side of the processing mechanism 8. The control system is installed inside the electrical box 9. The operation panel 10 is installed above the electrical box 9. The control system is electrically connected to the operation panel 10. The lower frame 11 with a flat plate structure is horizontally installed below the fixed rubber roller 1. The lower frame 11 is located between the adjacent sides of the rubber roller drive platform 3 and the processing mechanism 8. A scale 12 is installed on the upper surface of one side of the lower frame 11. The positioning reference baffle 13 with an inverted U-shaped structure is movably mounted on the lower frame 11. The fixed rubber roller 1 passes through the opening of the positioning reference baffle 13. The lower part of the front fixed rubber roller seat 7 and the lower part of the front lead screw mechanism 5 are fixedly mounted on the lower frame 11. The upper horizontal section of the cylindrical fixed rubber roller 1 is higher than the upper side of the housing of the front lead screw mechanism 5 and the processing mechanism 8. The cardboard tube 14 to be cut is placed on three parallel rubber rollers. The rotation of the three rubber rollers drives the cardboard tube 14 to rotate. At the same time, the upper part of the cardboard tube 14 is limited by the limit frame 6. The front end of the cardboard tube 14 extends into the processing range of the processing mechanism 8. During the rotation of the cardboard tube 14, the processing mechanism 8 realizes the automatic cutting of the cardboard tube 14.

[0029] like Figure 3 , Figure 4 , Figure 7As shown, the movable rubber roller 2 includes a rubber roller core 21 and a rubber layer 24 fixedly disposed on the outer periphery of the rubber roller core 21. A certain length of the rear end of the rubber roller core 21 is reserved without the rubber layer 24. A rear bearing 22 is fixedly installed on the outer periphery of the reserved length of the rear end of the rubber roller core 21 without the rubber layer 24. A double-row sprocket 23 is installed on the outer periphery of the rubber roller core 21 between the rear bearing 22 and the rear end of the rubber layer 24. The rubber layer 24 at the front end of the rubber roller core 21 is divided into two sections. A front bearing 25 is fixedly installed on the outer periphery of the rubber roller core 21 between the two sections of the rubber layer 24. The fixed rubber roller 1 includes a second rubber roller core, a second rubber layer, a second front bearing, a second rear bearing, and a double-row sprocket 27. The second rubber roller core is slightly shorter than the first rubber roller core 21. A section at the front end of the second rubber roller core has no rubber layer. The second front bearing is fixedly installed on the outer periphery of the section at the front end of the second rubber roller core. The other structures of the fixed rubber roller are the same as the movable rubber roller, and will not be described again here. The front end of the movable rubber roller 2 is rotatably mounted on the front movable rubber roller seat 4 via the first front bearing 25. The rear end of the movable rubber roller 2 passes through a rectangular opening at the upper front side of the rubber roller drive platform 3 and is rotatably mounted on the rear movable rubber roller seat 33 inside the rubber roller drive platform 3 via the first rear bearing 22. The front end of the fixed rubber roller 1 is rotatably mounted on the front fixed rubber roller seat 7 via the second front bearing. The rear end of the fixed rubber roller 1 passes through a circular opening in the middle of the front side of the rubber roller drive platform 3 and is rotatably mounted on the rear fixed rubber roller seat 34 inside the rubber roller drive platform 3 via the second rear bearing.

[0030] like Figure 1 , Figure 5 , Figure 6 As shown, the front movable rubber roller seat 4 includes a bearing seat 41, which is welded to a support column 42. The support column 42 is welded to a slider 43, and an internal threaded hole is formed at the center of the slider 43. The front lead screw mechanism 5 includes a bidirectional lead screw 51 and a groove 52. The left half of the bidirectional lead screw 51 has a left-hand thread, and the right half has a right-hand thread. The thread of the bidirectional lead screw 51 mates with the internal threaded hole on the slider 43. The two front movable rubber roller seats 4 are mounted on the front lead screw mechanism 5, one on the left and one on the right, in symmetrical positions. The upper middle part of the front fixed rubber roller seat 7 has the same structure as the front movable rubber roller seat 4, including a bearing seat and a support column. The lower end of the support column of the front fixed rubber roller seat 7 is fixedly welded to the lower frame 11. The geared motor 53 is fixedly mounted on one side of the front lead screw mechanism 5. The shaft of the geared motor 53 is fixedly connected to one end of the bidirectional lead screw 51, and the shaft of the geared motor 53 drives the bidirectional lead screw 51 to rotate. When the bidirectional lead screw 51 rotates, it drives the slider 43 to move, so that the two front movable rubber roller seats 4 on the left and right can move synchronously to the middle or the sides.

[0031] like Figure 7As shown, the rubber roller drive platform 3 includes a housing and an internal mechanism. The housing is a cuboid structure with an elongated opening on the upper part of the front side, the width of which is slightly larger than the diameter of the movable rubber roller 2. A circular opening is located in the middle of the lower part of the front side of the housing, the diameter of which is slightly larger than the diameter of the fixed rubber roller 1. The internal mechanism of the rubber roller drive platform 3 includes a sprocket motor 31, a rear lead screw mechanism 32, a rear movable rubber roller seat 33, a rear fixed rubber roller seat 34, and a second reduction motor 35. The second reduction motor 35 is located at one end of the rear lead screw mechanism 32. The sprocket motor 31 is fixedly installed on one side of the inner wall of the rubber roller drive platform 3 housing and is controlled by a control system within the electrical box 9. The rear lead screw mechanism 32 is fixedly installed inside the rubber roller drive platform 3 housing. The specific structure of the rear lead screw mechanism 32 is exactly the same as that of the front lead screw mechanism 5. The structure of the rear movable rubber roller seat 33 is exactly the same as that of the front movable rubber roller seat 4. The rear movable rubber roller seat 33 is threadedly mounted on the rear lead screw mechanism 32. The rear fixed rubber roller seat 34 is identical to the front fixed rubber roller seat 7, and is welded inside the housing of the rubber roller drive platform 3. The geared motor 35 on the rear lead screw mechanism 32 and the geared motor 53 on the front lead screw mechanism 5 are both controlled by the control system inside the electrical box 9 and operate synchronously, enabling the movable rubber roller 2 to move synchronously to the center or sides while always remaining parallel. Figure 8 As shown, three chains 26 are used to connect the shaft of the sprocket motor 31, the double-row sprockets 23 on the two movable rubber rollers 2, and the double-row sprockets 27 on the fixed rubber roller 1, so that one sprocket motor 31 drives the three rubber rollers to rotate synchronously. The rear side of the outer casing is a detachable steel plate, which facilitates the disassembly and assembly of the chains 26 or the maintenance of the internal mechanism of the rubber roller drive platform 3 after opening the steel plate.

[0032] like Figure 1 As shown, the limiting frame 6 includes a horizontal support arm, a rotating arm, and a rotating locking device. One end of the horizontal support arm is welded to the lower frame 11, and the other end of the horizontal support arm is connected to one end of the rotating arm via the rotating locking device. A limiting roller is fixedly installed on the other end of the rotating arm. Two symmetrical limiting frames 6 are provided on the left and right sides of the lower frame 11. After the cardboard tube 14 is placed in the sawing position, the rotating arm of the limiting frame 6 is manually rotated until the limiting roller is in close contact with and clamps the cardboard tube 14. Then, the rotating locking device is fully locked to achieve rotational limiting of the cardboard tube 14 and prevent the cardboard tube 14 from sliding or misaligning. The rotating locking device can specifically use an existing rotating shaft connection with bolt locking.

[0033] like Figure 1 , Figure 2As shown, the processing mechanism 8 includes a housing, a processing mechanism shaft 81, and a circular saw 82. The housing also includes a drive power supply, which drives the circular saw 82 to rotate. The housing is a cuboid with a step along the upper edge of its front side and a vertical rectangular slot in the middle. The processing mechanism shaft 81 is an L-shaped piece formed by welding two square tubes (a horizontal section and a vertical section). The lower end of the vertical section of the processing mechanism shaft 81 is connected to the housing via a pivot, located at the lower edge of the rectangular slot on the front side. The processing mechanism shaft 81 can rotate around the pivot, allowing the horizontal section of the shaft to be raised or lowered. One end of the horizontal section of the processing mechanism shaft 81 is welded perpendicularly to the vertical section, and the other end is connected to the circular saw 82 via a detachable fixed connection mechanism. The circular saw 82 is rotatably mounted in the fixed connection mechanism. The circular saw 82 is also electrically connected to the drive power supply inside the housing. After the drive power supply powers the circular saw 82, it rotates, which can then cut the cardboard tube 14.

[0034] The upper side of the lower frame 11 is provided with parallel baffle grooves along its length. The lower end of the inverted U-shaped positioning reference baffle 13 is movably mounted on the lower frame 11 through the baffle groove. The positioning reference baffle 13 can slide back and forth along the baffle groove and lock at the selected position according to the required cutting height of the cardboard tube 14. The locking mechanism is existing technology. A scale 12 is fixedly provided on the upper surface of one side of the lower frame 11. The zero mark of the scale 12 is aligned with the position of the circular saw 82.

[0035] The control system is a common electrical device, including an electrical box 9 and a control mechanism (such as a programmable logic controller) inside the electrical box 9. The control mechanism is electrically connected to the operation panel 10, the sprocket motor 31, the geared motor 53, and the geared motor 35. The operation panel 10 is equipped with multiple buttons for operating and controlling the rotation or stopping of the rubber roller, the rotation or stopping of the circular saw 82, and the inward or outward movement of the two movable rubber rollers 2.

[0036] In this first embodiment, the sawing process of the cardboard tube 14 is as follows:

[0037] First, remove the steel plate and open the roller drive platform 3. Remove the three chains 26 inside the roller drive platform 3 to adjust the spacing of the movable rollers 2. Based on the diameter of the cardboard tube 14 to be processed, use the buttons on the operation panel 10 to start the first reduction motor 53 and the second reduction motor 35 to adjust the spacing of the two movable rollers 2 until all three rollers are in contact with the cardboard tube 14. After determining the position of the movable rollers 2, determine the required chain length based on the center distance and diameter of each double-row sprocket. Select a suitable chain 26 to connect the shaft of the sprocket motor 31, the first double-row sprocket 23 of the two movable rollers 2, and the second double-row sprocket 27 of the fixed roller 1. Loosen the rotation locking device of the limit frame 6, and the rotating arm opens outwards. The diameter of the cardboard tube 14 is usually only a few fixed sizes, so the spacing of the movable rollers 2 does not need to be adjusted every time.

[0038] Install the circular saw 82 at one end of the processing mechanism shaft 81; rotate the processing mechanism shaft 81 outward to lift the circular saw 82; according to the target cutting height of the cardboard tube 14, move the positioning reference baffle 13 to the corresponding position according to the scale 12; manually operate the crane to transport the cardboard tube 14 onto the processing equipment, with the outer side of the cardboard tube 14 in contact with the three rubber rollers, and the rear edge of the cardboard tube 14 in contact with the positioning reference baffle 13. The positioning reference baffle 13 is used as a reference for placing the cardboard tube 14. After the cardboard tube 14 is placed in place, loosen the positioning reference baffle 13 and move it back to ensure that the positioning reference baffle 13 does not affect the rotation of the cardboard tube 14. Rotate the processing mechanism shaft 81 back to its original position and lower the circular saw 82. At this time, the circular saw 82 is at the target cutting position of the cardboard tube 14. Rotate the rotating arm of the limit frame 6 inward to make the limit roller close to the outer side of the cardboard tube 14, and then adjust and lock the rotation locking device of the limit frame 6.

[0039] Start the circular saw 82 and the rubber roller drive table 3 via the operation panel 10 to begin sawing. At the start of sawing, manually apply slight pressure to one end of the processing mechanism shaft 81 where the circular saw 82 is mounted, causing the circular saw 82 to cut through and penetrate the wall of the cardboard tube 14. The slow rotation of the rubber roller causes the cardboard tube 14 to rotate one revolution, completing one revolution of the circular saw 82. Turn off the circular saw 82 and the rubber roller drive table 3 via the operation panel 10; the sawing of the cardboard tube 14 is now complete. Example 2

[0040] In this second embodiment, the circular saw 82 is replaced with a rounded corner cutter head.

[0041] In this second embodiment, the process of rounding the corners of the cardboard tube 14 is as follows:

[0042] After the sawing operation is completed, rotate the machining mechanism shaft 81 outward to lift the circular saw 82, remove the circular saw 82 and replace it with a rounded corner cutter head. Rotate the machining mechanism shaft 81 back to its original position and lower the rounded corner cutter head.

[0043] Start the rounding cutter and rubber roller drive table 3 via the operation panel 10 to begin the rounding process. The rotating rubber roller drives the cardboard tube 14 to slowly rotate one revolution, and the rounding cutter completes the rounding of one edge of the cardboard tube 14. Turn off the rounding cutter and rubber roller drive table 3 via the operation panel 10, and the rounding of the cardboard tube 14 is complete. Finally, release the limit frame 6 and manually operate the crane to remove the finished cardboard tube 14.

[0044] In this embodiment of the utility model, all technical features not described in detail are existing technologies or conventional technical means, and will not be repeated here.

[0045] Finally, it should be noted that the above embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto. Those skilled in the art should understand that any person skilled in the art can modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this utility model; and these modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be covered within the protection scope of this utility model.
