Upper rubber 30 plays stabilization when shrinking, when preventing bottom rubber 28, middle layer rubber 29 and upper rubber 30 from shrinking
Skew, while the cambered surface of 27 vertical component effect upper end of stabilizing member can prevent from being scratched on middle net 32.The warp and weft one of spacer screen 38
As it is relatively thick, while quality is harder, and there is no need to apply tensile force to spacer screen 38.
Under the pulling force effect of veil 31, middle net 32 and spacer screen 38, while under the position-limiting action of limited block 26, on hot melt
The PP frame 35 of spacer screen 38, middle net 32 and veil 31 can be upturned towards one end of pulling off device, rotate revolving part 23, so that rolling
Wheel 24 is located at 19 right side of square tube, starts telescoping cylinder 16 later, so that the telescopic rod of telescoping cylinder 16 extends, when stretching for telescoping cylinder 16
After the completion of bar elongation, hooks pawl 18 and be located at below the gap between 35 frame of PP frame and its reinforcing rib, PP frame 35 is tilted upward later
The one end risen presses down on, so that hooking the bending part of pawl 18 in the gap between 35 frame of PP frame and its reinforcing rib, later
Revolving part 23 is rotated, so that the idler wheel 24 on revolving part 23 is located at 35 top of PP frame, prevents 35 one end of PP frame from tilting again, then
Starting telescoping cylinder 16 makes its telescopic rod bounce back, and when the telescopic rod of telescoping cylinder 16 pulls movable plate 17 to move to the right, passes through
The bolt of upper long hole 21 and lower long hole 22 moves to the right in lower long hole 22, and the opposite one end of two claws 20 tilts to the right,
One end that two claws 20 are located remotely from each other tilts to the left and by square tube 19 tight against PP frame 35, effective during stretching to guarantee
The stability of PP frame 35.
After hot melt has the PP frame 35 of spacer screen 38, middle net 32 and veil 31 to be drawn out vulcanizer 14, by another PP frame 35
It is placed on supporting plate 33, by spacer screen 38, middle net 32 and face after the above-mentioned movement for carrying out longitudinal stretching to veil 31 and middle net 32 of repetition
Net 31 is thermally melted on the PP frame 35 of 34 lower section of heating plate, then cuts off spacer screen 38, middle net 32 and veil 31, the PP that will be processed for the first time
Frame 35 is removed, so that pulling off device pulls out the PP frame 35 in vulcanizer 14, continuous add is can be realized in circulation above-mentioned steps
Work.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.

Direction movement, veil (31) and middle net (32) are longitudinally stretched at this time, heating plate (34) make spacer screen (38), middle net (32) and
Veil (31) presses closer PP frame (35) and spacer screen (38), middle net (32) and veil (31) is thermally melted on PP frame (35), works as heating plate
(34) after rising reduction, upper rubber (30), middle layer rubber (29) are separated with middle net (32) and veil (31), in veil
(31), under the pulling force effect of middle net (32) and spacer screen (38), while under the position-limiting action of limited block (26), spacer screen on hot melt
(38), the PP frame (35) of middle net (32) and veil (31) can be upturned towards one end of pulling off device, rotate revolving part (23),
So that idler wheel (24) is located on the right side of square tube (19), start telescoping cylinder (16) later, so that the telescopic rod of telescoping cylinder (16) extends, when
After the completion of the telescopic rod elongation of telescoping cylinder (16), hooks pawl (18) and be located under the gap between PP frame (35) frame and its reinforcing rib
Side, one end that PP frame (35) is upturned later press down on, so that hooking the bending part of pawl (18) in PP frame (35) frame
In gap between its reinforcing rib, revolving part (23) are rotated later, so that the idler wheel (24) on revolving part (23) is located at PP frame
(35) top, prevents PP frame (35) one end from tilting again, and then starting telescoping cylinder (16) makes its telescopic rod bounce back, in telescoping cylinder
(16) when telescopic rod pulls movable plate (17) to move to the right, the bolt of upper long hole (21) and lower long hole (22) is passed through in lower length
Is moved in hole (22) to the right, the opposite one end of two claws (20) tilts to the right, one end that two claws (20) are located remotely from each other to
Left side simultaneously passes through square tube (19) tight against PP frame (35), effectively guarantees the stability of PP frame (35) during stretching, when
After hot melt has the PP frame (35) of spacer screen (38), middle net (32) and veil (31) to be drawn out vulcanizer (14), by another PP frame
(35) it is placed on supporting plate (33), by spacer screen after the above-mentioned movement for carrying out longitudinal stretching to veil (31) and middle net (32) of repetition
(38), middle net (32) and veil (31) are thermally melted on the PP frame (35) below heating plate (34), then cut off spacer screen (38), middle net
(32) and veil (31), the PP frame (35) processed for the first time is removed, so that pulling off device is by the PP frame (35) in vulcanizer (14)
Continuous maching can be realized in pull-out, circulation above-mentioned steps.
