The heater is connected on the pyrotoxin and for being held in diaphragm.The neighbouring pinch roller of pressing of the heater is set,
And positioned at the upstream for pressing pinch roller, i.e., by heating of the heater to the diaphragm, then the pinch roller of pressing just will tool
Sticking diaphragm is pressed on the metallic plate, to adsorb the dust on the metallic plate.For example, the pyrotoxin is electric heating
Source, the heater are resistance heater, and the supporting piece is connected to the cover and sets on body and be held on the heater, uses
So that the heater is held on diaphragm.For example, for the ease of being sticked on the diaphragm, the heater is cylindrical body, institute
The bottom of heater is stated formed with arc contact surface, the arc contact surface is used to contact diaphragm.For example, the heater rotates
Ground is connected to the cover and sets on body and be electrically connected with by cable and the pyrotoxin.For example, the heat generating component also includes note
Recall elongate member made of alloy, one end of the elongate member is connected to the cover and set on body, and the other end is tilted towards described by pinch roller
Extension.The end of the heater is connected to one end that the elongate member sets body away from the cover.For example, the elongate member is piece
Body shape, the width of the elongate member are gradually reduced along the direction for setting body away from the cover.When the heater adstante febre, it is by heat
Amount is transferred on the elongate member, and the elongate member is then by thermal stretching, so as to promote the pressing body to be held on diaphragm, then
Realize the heating to diaphragm.For example, in order to improve heating effect so that described press on pinch roller also has certain temperature, described
Formed with shoe contact site, the shoe contact site is concavely provided with shoe heating surface, the shoe heating surface for the side of heater
Direction is described to be coordinated by pinch roller and with described by pinch roller, so as to which the pressing layer pressed on wheel surface is heated, so as to
Improve the viscosity of the diaphragm.Because the pressing layer of the pressing wheel surface is firm layer or stainless steel layer, therefore it is easy to receive
The heat that the heater is sent.For example, the shoe heating surface and the formation heating gap between pressing pinch roller, so that
The shoe heating surface can be transferred heat to described by pinch roller by way of radiant heating.When the metal need not be transmitted
During plate, the pyrotoxin then stops powering to the heater, and the heater cooling, now the extensible member then shrinks, from
And the heater is pulled away from the transmission frame, and then be advantageous to overhaul the carriage.For example, heated for the ease of improving
Effect, the heating component also include rotary body, and the rotary body is cylinder, and the rotary body is slidingly arranged at the cover and set
On body, and it is connected with the heater.For example, the heater presses the side of pinch roller formed with oval convex surface, institute away from described in
State ellipsoid convex surface and abut the arc contact surface, when the heater presses pinch roller described in, the rotary body can drive
The heater rotation so that the oval convex surface of the heater approaches the diaphragm, while shoe heating surface alignment institute
State the surface by pinch roller.When that need not heat, the rotary body can drive it is described rotated by pinch roller, and coordinate the extensible member
Motion so that the oval convex surface is away from diaphragm.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that the ordinary skill people for this area
For member, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the present invention's
