The invention also provides a calendering method using a three-roll calender of a flashing as defined in any of the above, comprising the steps of,
s1, adjusting the second calender roll 7 to be lifted and the third calender roll 8 to be lowered by an adjusting mechanism;
s2, the waterproof board to be calendered passes through the space between the third calendering roller 8 and the first calendering roller 2 and the space between the second calendering roller 7 and the first calendering roller 2;
s3, adjusting the second calender roll 7 to be lowered and the third calender roll 8 to be raised by the adjusting mechanism, and applying set pressure to the waterproof board;
s4, starting a driving mechanism, and calendering the waterproof board by the first calendering roller 2, the second calendering roller 7 and the third calendering roller 8;
in S1 and S3, the second calender roll 7 and the third calender roll 8 are synchronously lifted and lowered through transmission by a first steering wheel 9, a second steering wheel 10, a third steering wheel 11, a fourth steering wheel 12 and a transmission piece 13.
When the waterproof board is calendered, firstly, the adjusting mechanism adjusts the second calender roll 7 to be lifted and the third calender roll 8 to be lowered; then, the waterproof board to be calendered passes through the space between the third calender roll 8 and the first calender roll 2, and the space between the second calender roll 7 and the first calender roll 2; then the adjusting mechanism adjusts the second calender roll 7 to be lowered and the third calender roll 8 to be raised, and applies set pressure to the waterproof board; the driving mechanism is started, and the first calender roll 2, the second calender roll 7 and the third calender roll 8 calender the waterproof board; in S1 and S3, the second calender roll 7 and the third calender roll 8 are synchronously lifted and lowered through transmission by a first steering wheel 9, a second steering wheel 10, a third steering wheel 11, a fourth steering wheel 12 and a transmission piece 13.
The first lifting block 5 and the second lifting block 6 are linked through the transmission piece 13, the first steering wheel 9, the second steering wheel 10, the third steering wheel 11 and the fourth steering wheel 12, so that the first lifting block 5 and the second lifting block 6 can realize the inefficiency of acting force between each other; namely, when the second calender roll 7 is lifted, the weight of the third calender roll 8 can provide an upward pulling force to the second calender roll 7 after passing through the transmission piece 13, thereby the lifting of the second calender roll 7 is simpler and more convenient; similarly, when the third calender roll 8 is lifted, the weight of the second calender roll 7 can exert an upward tensile force on the third calender roll 8, so that the heights and the reductions of the second calender roll 7 and the third calender roll 8 are simple and convenient, and compared with the prior art that a power mechanism for driving is required to be arranged independently to lift the second calender roll 7 and the third calender roll 8, the structure of the device can greatly reduce the required power and reduce the input requirement on equipment.
The mass of the second calender roll 7 is larger than that of the third calender roll 8, when the driving mechanism drives the second calender roll 7 and the third calender roll 8 to lift, partial effect can be consumed, and the second calender roll 7 is positioned above the third calender roll 8, so that even if partial consumption exists, the self weight of the second calender roll 7 can better balance the mass and partial loss of the third calender roll 8.
When the second calender roll 7 and the third calender roll 8 are lifted and lowered, firstly, the adjusting worm 20 is driven by the motor to rotate, and at the moment, the adjusting worm 20 drives the two adjusting worm wheels 18 to rotate; when the adjusting turbine 18 rotates, the adjusting rod 17 is driven to rotate; since the adjusting lever 17 is rotatably connected with the supporting block 16, the position of the adjusting lever 17 itself is not fixed; however, the adjusting rod 17 is in threaded fit with the first lifting block 5 and the second lifting block 6, so that the first lifting block 5 and the second lifting block 6 are lifted and lowered under the action of the threads of the adjusting rod 17; meanwhile, the thread directions of the upper half part and the lower half part of the adjusting rod 17 are opposite, so that the adjusting rod 17 can simultaneously drive the second calender roll 7 and the third calender roll 8 to reversely lift when rotating, and the load of the transmission piece 13 is reduced; meanwhile, the transmission piece 13 can transmit the weight of the second calender roll 7 and the third calender roll 8, so that the load of the adjusting rod 17 is smaller in the actual use process;
moreover, since the adjusting rod 17 is synchronously screwed with the first lifting block 5 and the second lifting block 6, the distances between the second calender roll 7 and the third calender roll 8 and the first calender roll 2 are equal, and the calendering quality is ensured.
After being drawn out from the first lifting block 5, the top of the transmission part 13 sequentially bypasses the first steering wheel 9, the second steering wheel 10, the third steering wheel 11, the fifth steering wheel 14, the sixth steering wheel 15 and the fourth steering wheel 12 (all chain wheels matched with a chain), and then is connected with the second lifting block 6, so that the transmission part 13 (namely the chain) can better transmit acting force to a required position; simultaneously the corner of driving medium 13 also can be better goes on, prevents that driving medium 13 from taking place deformation or fracture.
In the calendering process, the driving motor 21 drives the driving gear 22 to rotate, and the driving gear 22 drives the first gear 23 on one side to rotate; meanwhile, the first gear 23 drives the second gear 24 and the third gear 25 to rotate through the upper side and the lower side of the first gear respectively, so that the second calender roll 7 and the third calender roll 8 are driven to rotate, and the waterproof board is calendered. Because the adjusting rod 17 still receives a certain acting force in the calendering process, the adjusting worm gear 18 is limited by the adjusting worm 20, the positions of the second calender roll 7 and the third calender roll 8 are ensured, and the calendering quality is ensured.
As the time of use increases, the transmission member 13 tends to loosen, and therefore some adjustment is usually required to keep the transmission member 13 properly tensioned; during adjustment, the stabilizing cylinder 29 is moved upwards firstly, the top of the stabilizing cylinder 29 is magnetically attracted by the limiting disc 31, and the bottom of the stabilizing cylinder 29 is separated from the positioning part 28; then, fixing the top of the adjusting stud 27 by using a wrench or the like to prevent the adjusting stud from rotating; then, a wrench is used to rotate the positioning piece 28, so that the adjusting screw 26 and the adjusting stud 27 rotate relatively, and the adjusting screw 26 further enters the adjusting stud 27; when the tension of the transmission member 13 reaches a proper value, the stabilizing cylinder 29 is pulled down, so that the stabilizing cylinder 29 is separated from the limiting disc 31 until the bottom of the stabilizing cylinder 29 finally abuts against the supporting disc 30, and at the moment, the top and the bottom of the stabilizing cylinder 29 are respectively buckled on the outer walls of the adjusting stud 27 and the positioning member 28, so that the positioning member 28 and the adjusting stud 27 cannot rotate relatively, and the tension of the transmission member 13 can be stably maintained. During the rotation of the positioning member 28, the engagement housing 34 and the rotating ball 33 perform relative rotation therebetween.
The limiting disc 31 is weak in magnetism, and only can simply play a temporary fixing role on the stabilizing cylinder 29 in practical use, and after the stabilizing cylinder 29 is separated from the limiting disc 31, the stabilizing cylinder 29 cannot be sucked up by the limiting disc 31; secondly, if the angle positioning piece 28 and the adjusting stud 27 are not opposite, the stabilizing cylinder 29 can be sleeved after the positioning piece 28 and the adjusting stud 27 are relatively rotated by a small angle; due to the variability of the tension of the transmission member 13, the normal tension of the transmission member 13 is not affected even if the relative rotation is performed by a small angle.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
