Detailed Description
The invention will be further described with reference to specific embodiments and the accompanying drawings in the description, without limiting the scope of the invention thereto.
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: the utility model provides an oil-immersed transformer cardboard glues machine admittedly, includes following technical scheme: the feeding device comprises a workbench 1, wherein hydraulic equipment 2 is fixedly arranged on the upper surface of the workbench 1, a feeding platform 4 is fixedly arranged 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;
double-deck feeding eyelidretractor 6 includes collateral branch frame 7, the equal fixed mounting in surface of collateral branch frame 7 has four bearings 9, and collateral branch frame 7 left upper portion and the homogeneous integrated into one piece in lower part have a support flitch 8, jack 11 has all been seted up at the middle part of collateral branch frame 7, and collateral branch frame 7 welds the left end in the material platform 4 upper surface of walking, insulating oil shower nozzle 12 has all been pegged graft to the inside of jack 11, evenly rotate between two collateral branch frames 7 and be connected with and bearing 9 fixed connection's roller bearing 10, hydraulic means 2 pointed out herein is the complete hydraulic pressure thrust device commonly used among the prior art, for the common core subassembly of current hot press, also can use the roll-in device to replace, double-deck feeding eyelidretractor 6 uses the bilayer herein as the example, but the layering feed structure of this subassembly can increase and decrease according to the.
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, the lower end of the hydraulic device 2 is fixedly mounted with the pressure plate 3.
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 sharp nozzle tube 18, the right end of the sharp nozzle tube 18 is uniformly provided with dense pinhole-type nozzles 19, and the sharp nozzle tube 18 is screwed to the right end of the thin elbow 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-oil immersion operation on the surface of the paper board of the inner interlayer before hot pressing, and oil supply equipment for insulating oil is screwed at the outer end of the threaded pipe 13, so that the nozzle 17 can carry out oil injection operation on the interlayer before the paper board is hot pressed; 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.
Example two:
referring to fig. 1, fig. 2, fig. 3 and fig. 5, a second technical solution provided by the present invention is different from the first technical solution in that:
particularly, the nozzle 17 comprises a flat nozzle body 20, the right end of the flat nozzle body 20 is provided with strip-shaped dense pinhole type spray holes 21, the right side wall of the flat nozzle body 20 is uniformly embedded with brush bristles 22, the flat nozzle body 20 is in threaded connection with the right end of the thin bent pipe 14, the nozzles 17 can be closely arranged side by side to cover the surface of the paperboard, the length of the nozzles can be controlled by the number of the assembled nozzles 17, and compared with a long flat nozzle which is directly used, the nozzles are better in adaptability and convenient to replace and maintain.
The working principle is as follows:
through using the nozzle 17 of suitable quantity to carry out the oil spout operation to the intermediate layer, because the end of flat nozzle body 20 has brush hair 22, so should be equipped with multiple length specification when this kind of nozzle 17 makes, guarantee that the brush hair 22 can contact the surface of cardboard after the assembly, the required oil spout working gas pressure of this nozzle is less, guarantee that fluid can spray to the brush overhead with flat line type can, brush hair 22 can play the effect of even coating to this obtains more even preimpregnation oil effect.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
