Definitions

  • PLATE HEATER 72 Inventor: Adolf F. Beaten, St. Paul, Minn.
  • PLATE mm BACKGROUND AND SUMMARY OF THE INVENTION This invention relates to the field of plate heaters for use in the synthetic fiber industry. Further the apparatus relates to the use of easily replaceable draw plates or wear plates. In the prior art the wear plate and heating elements were often bonded together or elaborately clamped together so that they had to'be removed from the machine together when the wear plate surface became worn. This meant removal of the heater wiring as well as the wear plate and heater elements and much time was consumed in the replacement as well as the high. cost of replacing both heaters and wear plate. In the present invention, heater and sensor-are mounted on a spring loaded support plate and contained in a sheet metal housing.
  • the heater plate fits on top-of the heater/sensor assembly and by pressing against the spring support slips into position, in which it is retrained. by two screws. If replating or exchange of the plate becomes necessary, only these two screws have to be loosened and the plate can be easily and quickly removed thereby sensitive wire embedded in a suitable material.
  • the plate heater is made so that the plate 13 can be easily replaced whenever necessary.
  • Slots 30 in one end of the plate 13 cooperate with ro ctions extending inward] such as inwardly projecting fi i re studs 31 in the mounting base 10, and slots 32 in the opposite end of plate 13 cooperate with screws 33 and threaded holes 34 of the base to detachably secure the plate ,13 to the base 10.
  • End plate 11 and 12 are tapped to receive screws 35, these screws being positioned into slots 36 of base 10 andtightened to secure the end plates. This arrangement allows easy assembly and disassembly of the plate heater apparatus for replacement of the plate.
  • FIG. 1 is an overall view of the plate heater
  • FIG. 2 is a cross-sectional view taken through FIG. 1 at point 2--2;
  • FIG. 3 is an exploded view of the apparatus of FIG. 1.
  • FIG. 1 there is disclosed a side elevation of the plate heater including a mounting base 10, end plates 11 and 12, and a replaceable channel shaped draw plate or wear plate 13 along the surface of which the yarn or fiber is to be drawn.
  • the plate 13 has channel edges 13a and a longitudinally curved surface 13b so that the moving yarns may be in contact with the heated plate surface for the entire length of the plate.
  • the replaceable wear plate 13 forms the outer component of the plate and heater assembly 14.
  • Fork shaped heater element 15 which may be in the order of 0.020 inch thick is designed to fit into unifonn thermal contact with the draw plate and comprises'a flexible insulating member of glass-fiber-reinforcedsilicone rubber having an etched foil type electrical heater element embedded in and extending throughout the strip to provide heating of the entire plate surface 13b, the heating wire terminals being brought out at conductors l6 and 17 for connection to a suitable source of power.
  • the metal backing strip 21 has end tabs 22 and 23 which fit into slots 24 in the end plates 11 and 12 respectively to locate and hold the ends of the heater subassembly.
  • a coil spring 25 is positioned in the middle of the plate between backing strip 21 and mounting base 10 to urge the heating subassembly tightly against plate 13.
  • the compressible rubber member 20 powered by the spring steel backing strip 21 and the coil spring 25 forces all portions of the heater element against the wear plate.
  • temperature sensor 26 which is dimensioned to fit into the slot area 27 of the forked heater 15 and to be pressed against the plate 13 by the heater subassembly to sense the heat of the plate surface 13b and to provide an output which is a function thereof which can be sensed at terminals 28.
  • Sensor 26 may be in the form of a temperature 15, 20, 21 and 26 remains mounted onbase member 10;
  • An electrically heated plate heater apparatus for heat treating moving synthetic fibers in which the'wear plate can be easily detached from the electrical heating element and the remainder of the apparatus for rapid replacement of the wear sandwich construc-' tion assembly'comprising in order:
  • an elongated wear plate member having a curved elongated exterior surface to be heated and upon which heated surface moving fibers pass to be treated;
  • heater means separate from the wear plate member and having an elongated shape to match said wear' plate member and positioned in heating relation to said wear plate member;
  • metal backing plate means having an elongated shape to match said heater means
  • elongated base member mounting means for supporting said assembly, saidfmounting means comprising first means for mounting said heater means together with said backing plate means and removable fastening means for detachably mounting said wear plate member to said mounting means;
  • said backing plate means forcing said heater means into uniform thermal contact with said wear plate member over the length thereof when said wear plate member is fastened to said mounting means.
  • said heater means comprisesi a flexible heater element having an elongated shape to match said wear plate material positioned in heating relation to said wear plate member;
  • a compressible strip having an elongated shape to match said heater element.
  • said backing plate means comprises spring means such as a stainless steel backing plate having an elongated shape to match said heater means.
  • said spring means further comprises coil spring means positioned between said steel backing plate and said base member mounting means.
  • said spring means further comprises coil spring means positioned between said backing plate and said base member mounting means so that said coil spring means, said backing plate and said compressible strip are compressed and bias said flexible heater element into uniform thermal contact with said wear 7 plate member over the length thereof when said wear plate
