Operation principle:Before use, selecting the type of fixture according to the heater type of production, as shown in figure 13, work as fever
When insulation board 6 in body is single side wrapping wire, the single side wrapping wire fixture as shown in Fig. 5,6,7 is selected.In specific production, by flowing water
The insulation board that line is conveyed through is fed band 12 and transports into this equipment.When insulation board is moved at positioning baffle 13, determined
Position baffle and cannot move on, at this time, positioning push plate 14 move, insulation board is pushed to the side wall of cradle.Pass through two
Insulation board is moved at the origin of material fetching mechanism by the mode of point location.
Feeding slider-actuated feeding sucker in material fetching mechanism is drawn insulation board out of feed mechanism and is sent into winding mechanism.
In winding mechanism fixture clamping insulation board after, material fetching mechanism be reset to origin draw again insulation board be sent into other side around
In silk mechanism.Due to the winding mechanism in this case, welding mechanism, wire feeder is both provided with two sets, is symmetrically mounted on feeder
Structure both sides, therefore be conducive to improve production efficiency, while the structure of equipment is also more compact.
After fixture clamps insulation board, heating wire is transported to the electrode on insulation board plate by wire feeder by wire feeding mouth
Place, while weld rifle 52 and move to designated position under the driving of welding sliding block, then weld rifle and weld heating wire 7 and electrode 61
Connect, then welding mechanism resets.
Then the clockwise or counter-clockwise swing under the driving of coiling electric motor 33 of fixture 32, simultaneously, wire feeding mouth exists
Front and rear and side-to-side movement under the action of wire feed slide unit, by heating wire around the home in the card slot on insulation board.Wherein due to insulation board
Quality is frivolous, it is difficult to which pulling force when bearing heating wire 7 around the home, particularly is provided with coiling support axle construction in this case.Such as Fig. 7, Fig. 9 institutes
Show, coiling support axis 34 is provided with two, is symmetrically mounted on fixture both sides and positioned at insulation board buckle lower section.When insulation board wrapping wire
When, heating wire is around the home on the hook of coiling support axis.After wrapping wire is completed, actuating unit driving coiling support axis rotates so that hangs
Hook 35 departs from heating wire.
After wrapping wire is completed, heating wire and another electrode welding, after the completion of welding, the pneumatic clipper on wire feeder 4
Heating wire is cut short the wrapping wire that can complete one piece of insulation board by knife 9.Simultaneously, the feeding sucker in feed mechanism is out of fixture
Finished product is drawn, then feeding sucker rotates 180 °, and the insulation board of non-wrapping wire is put into wrapping wire in fixture.Last feeding sucker is answered
Position, places products into feeding belt and transports, while draws the insulation board of non-wrapping wire.Feeding sucker can be completed to take in once moving
Material and two steps of feeding, can be greatly improved production efficiency.
Wherein it should be noted that:As shown in figure 8, when insulation board is two-sided wrapping wire, it is only necessary to cancel coiling support axis knot
Structure, while coiling electric motor drives fixture to that rotating Vortex some weeks the two-sided wrapping wire of insulation board can be completed.
Compared with conventional art, the structure in this case can whole-course automation completion insulation board single side or two-sided wrapping wire work
Industry, while production efficiency is increased substantially, also helps the quality for ensureing product, therefore can be widely popularized use.
The advantages of basic principle and main feature and the utility model of the utility model has been shown and described above.One's own profession
