The first embodiment is as follows:
referring to fig. 1, fig. 2, fig. 3 and fig. 4, a first technical solution provided by the present invention is: a paperboard hot bonding machine for an oil-immersed transformer comprises the following technical scheme: the feeding device comprises a workbench 1, wherein hydraulic equipment 2 is fixedly mounted on the upper surface of the workbench 1, a feeding platform 4 is fixedly mounted on the upper surface of the workbench 1, and a double-layer feeding support 6 is welded at the left end of the feeding platform 4;
the double-layer feeding support 6 comprises side supports 7, four bearings 9 are fixedly mounted on the surfaces of the side supports 7, material supporting plates 8 are integrally formed on the upper portion of the left side of each side support 7 and the lower portion of the left side of each side support 7, insertion holes 11 are formed in the middle of each side support 7, each side support 7 is welded to the left end of the upper surface of the material conveying platform 4, insulating oil spray heads 12 are inserted into the insertion holes 11, rolling shafts 10 fixedly connected with the bearings 9 are uniformly and rotatably connected between the two side supports 7, the hydraulic equipment 2 indicated in the text is a common complete hydraulic pushing device in the prior art and is a common core component of an existing hot press, the rolling devices can also be used for replacement, the double-layer feeding support 6 is exemplified by double layers in the text, the layered feeding structure of the double-layer feeding support can be increased or decreased according to needs, and the number of the double-layer feeding support is two.
Specifically, insulating oil nozzle 12 includes screwed pipe 13, and the rear end integrated into one piece of screwed pipe 13 surface has annular flange 15, and the rear end welding of screwed pipe 13 has thin return bend 14, and the front side spiro union of screwed pipe 13 surface has fastening ring 16, and screwed pipe 13 pegs graft in jack 11, and thin return bend 14's end spiro union has nozzle 17 again, and thin return bend 14 can prolong the pipe length as required to this increases nozzle 17 interface quantity, carries out intermediate layer oil spout operation to the cardboard that the width is wideer.
Specifically, a pressure plate 3 is fixedly mounted to a lower end of the hydraulic device 2.
Specifically, the heating device 5 is fixedly mounted on the lower portion of the working table 1, the heating device 5 is electrically connected to a power supply through an internal wire, the heating device 5 is a device for heating the surface of the feeding platform 4 from the lower side through components such as an electric heating tube, and the like, and is a common device component in the market, so detailed description is omitted here.
Specifically, the nozzle 17 includes a pointed nozzle tube 18, the right end of the pointed nozzle tube 18 is uniformly provided with dense pinhole type spray holes 19, and the pointed nozzle tube 18 is screwed to the right end of the thin bent tube 14.
The working principle is as follows:
the left side of the double-layer feeding support 6 is connected with a sheet feeding device of the paper boards, two rolling shafts 10 are in a group, each group of rolling shafts corresponds to a feeding conveying belt of one layer of paper boards, the feeding conveying belts play a role in guiding and fixing the fed paper boards, and after the paper boards are fed to the lower side position of the hydraulic equipment 2, conventional ironing operation is carried out; because the uppermost layer and the lowermost layer of the paper board are polished surfaces and the material of the paper board is different from that of the inner interlayer, the device carries out pre-immersion oil operation on the surface of the paper board of the inner interlayer before hot pressing, and oil injection operation can be carried out on the interlayer of the paper board before hot pressing by the nozzle 17 through the oil supply equipment which is screwed with insulating oil at the outer end of the threaded pipe 13; therefore, the paperboard is immersed in oil in advance and then is subjected to hot pressing operation, the paperboard is immersed in oil to expand and deform to a certain degree, the amount of the oil needed to be absorbed by the paperboard after being immersed in the insulating oil is reduced compared with the prior art when the paperboard is used, and the deformation degree of the paperboard is far smaller than the deformation generated by directly immersing the insulating paperboard in the insulating oil, so that the internal stress generated by expansion after the insulating paperboard is immersed in oil is reduced, and the tolerance and the quality of the paperboard during immersion in oil are improved;
by using a proper number of nozzles 17 to perform oil spraying operation on the interlayer, the end of the sharp nozzle tube 18 is provided with the dense pinhole type spray holes 19, so that the required working air pressure is higher when oil is sprayed, the sprayed oil beam is thinner and has better penetrating power, and the oil has better penetrating effect.
