TECHNICAL FIELD
[0001] The present application relates to the field of oil-immersed transformer, in particular to an automatic bonding oil channel machine device for interlayer insulation of oil-immersed transformer. BACKGROUND
[0002] The distribution transformer is one of the important equipment in the power supply system of industrial and mining enterprises and civil buildings, which reduces the 10 (6) kV or 35 kV network voltage to the 230 / 400V bus voltage used by users. The transformer oil is a liquid of petroleum, which has the possibility of burning and has shortcomings in environmental protection. However, due to the excellent performance and low price of transformer oil, most power transformers still use transformer oil as insulation and cooling medium. In the production process of oil-immersed transformer, long strip-shaped oil channel support strips are needed to be pasted with oil paper to form oil channels to ensure the circulation of oil. The existing point gluing type oil channel pasting equipment cannot uniformly apply glue, which will cause the glue to accumulate and expose on the periphery of the support strip or cause the insulation paper to deform slightly. Therefore, after winding, the oil channel inside is deformed or blocked, and the oil channel is unevenly distributed. In view of the above problems, the present application provides an automatic bonding oil channel machine device for interlayer insulation of oil-immersed transformer. SUMMARY
[0003] The present application aims to provide an automatic bonding oil channel machine device for interlayer insulation of oil-immersed transformer to solve the problems in the background art.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Please see Figures 1-6 This invention provides a technical solution: an automatic bonding oil channel machine for interlayer insulation of an oil-immersed transformer, comprising an insulation bar stacking device 1 and a feeding conveyor belt 2. A glue application conveying mechanism 4 is mounted at the rear end of the feeding conveyor belt 2, and an adhesive conveyor belt 5 is mounted at the rear end of the glue application conveying mechanism 4. An insulation strip 3 and insulation paper 7 are sleeved on the inner surface of the adhesive conveyor belt 5. A glue replenishing device 6 is mounted between the inner surface of the insulation paper 7 and the insulation strip 3 at the end. The insulation bar stacking device 1 is installed vertically, and the width of the feeding conveyor belt 2 is smaller than that of the insulation strip 3. The width of strip 3 is the same as the width of adhesive conveyor belt 5 and the width of feeding conveyor belt 2. The glue application conveyor mechanism 4 includes a fixed plate 41. The bottom end of the fixed plate 41 is equipped with a first conveyor roller 46 and the top end of the fixed plate 41 is equipped with a second conveyor roller 47 that can be raised and lowered. The outer surfaces of the first conveyor roller 46 and the second conveyor roller 47 are both sleeved with a first conveyor belt 48. The glue application device 6 includes a conical isolation frame and a conical glue application cone 36 set at the front and rear ends. The upper surface of the isolation frame and the glue application cone 36 coincides with the lower surface plane of the insulating strip 3.
[0023] This invention provides an automated integrated structure for stacking, conveying, gluing, and bonding of insulating strips. In use, the insulating strips descend at a uniform speed from the insulating strip stacking device 1 to the upper surface of the feeding conveyor belt 2, and are then conveyed backward to the inside of the gluing conveyor mechanism 4. After being clamped at both ends, the gluing mechanism applies glue to the middle of the lower surface of the insulating strip 3. Then, it is bonded together with the insulating paper conveyed by the bonding conveyor belt 5. Subsequently, the two ends are separated by the glue replenishment device 6, which facilitates the glue application cone 63 to apply glue to the lower surface of the outer end of the insulating strip 3 for replenishment. This effectively solves the problem of uneven glue application in existing dot-type oil channel bonding equipment, which causes uneven oil channels after winding.
[0024] Specifically, the insulating strip stacking device 1 includes a support bar 11, a lifting rod 12 is mounted on the rear surface of the support bar 11, a chain frame 13 is mounted on the rear surface of the lifting rod 12, a connecting chain 14 is hinged to the bottom end of the chain frame 13, and a stop bar 15 is mounted on the front surface of the chain frame 13. The front surface of the stop bar 15 is tightly attached to the rear surface of the lifting rod 12. Multiple sets of chain frames 13 and connecting chains 14 form a ring-shaped chain lifting conveyor belt, which evenly stacks the insulating strips 3 on the upper surface of the feeding conveyor belt 2 from top to bottom, thereby achieving the purpose of evenly spaced stacking.
[0025] Specifically, the side surface of the fixing plate 41 is integrally formed with a slide rail 42, and the inner surface of the slide rail 42 is fitted with a slide shaft 44. The inner surface of the slide shaft 44 is fitted to the outer end of the second conveying roller 47. When insulating strips 3 of different thicknesses enter, the slide shaft 44 and the second conveying roller 37 press the insulating strip 3 to ensure smooth transmission, provide clamping force, and avoid affecting its relative position during the glue application process.
[0026] Specifically, the bottom end of the fixed plate 41 is provided with a shaft hole 43, and the inner surface of the shaft hole 43 is sleeved on the outer end of the first conveying roller 46.
[0027] Specifically, a slide rod 45 is fitted at the top of the slide shaft 44. The slide rod 45 is sleeved on the top of the slide rail 42. The outer surface of the slide rod 45 can adopt a spring structure, which can automatically jump to adapt to the clamping height when the insulating strip 3 of different thicknesses enters. Alternatively, a nut structure with a height that is fixed relative to the dust cover 49 can be screwed through the outer surface of the dust cover 49, which is conducive to the rotation of the structure to adjust the lifting and lowering of the slide rod 45. The latter method is preferred.
[0028] Specifically, the outer surface of the fixing plate 41 is fitted with a dust cover 49.
[0029] Specifically, the bonding conveyor belt 5 includes a third conveyor roller 51, with a connecting plate 52 mounted on the outer end of the third conveyor roller 51, and a second conveyor belt 53 sleeved on the outer surface of the third conveyor roller 51.
[0030] Specifically, the feeding conveyor belt 2 and the bonding conveyor belt 5 are identical in size and structure except for the conveying stroke.
[0031] Specifically, the isolation frame includes a first isolation frame 61 and a second isolation frame 62. The first isolation frame 61 and the second isolation frame 62 are assembled on the front and rear sides of the glue-applying cone 63. When the isolation frame is in use, as shown in Figure 6, the insulating paper is divided into four functional areas according to different processing states: the feeding section at 71, which is transported upward and backward along the bottom of the adhesive conveyor belt 5; the positioning area at 72, which is pasted with the middle of the insulating strip 3; the folding area at 73, which is used for glue application; and the forming area at 74. The insulating paper 7 is passively transported from front to back and is bonded to the adhesive and the insulating strip 3. The unpainted insulating paper 7 is flipped downward by the inclined conical structure of the isolation frame, which facilitates the application of glue by the smaller glue-applying cone 63. The position of the feeding section in the figure is only an example. In actual applications, it needs to be staggered from the bottom structure of the glue-applying conveyor mechanism 4.
[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
