Rubber-coated mechanism 2 and structural similarity of the prior art do not repeat them here.

The course of work of the utility model device is described below in conjunction with Fig. 1.Can further understand the structure of all mechanisms thus.

At first, by sending into core paper from core paper conveying mechanism 6 manually, when core paper arrives on the line that is in contact with one another of upper and lower corrugation roller 5 and 4,, thereby upper corrugated roller 5 is upwards boosted because core paper itself has certain thickness.This will make framework 10 rotate around the bearing pin 47 of its end, and its end that links to each other with pulling force governor motion 11 is also upwards rotated around bearing pin 47, this rotation compression spring 28.The rotation of this end will excite the sensor 23 that is arranged at pulling force governor motion 11 sides, and make its closure.As previously mentioned, the closure of sensor 23 will make with it electromagnet 18 energisings in the facial tissue conveying mechanism that is electrically connected, and attract its armature downwards.Lever dolly 14 is clockwise rotated around mandrel 28 under pull bar 19 effects that link to each other with armature, finally cause upper and lower dancing roll 15,16 to contact.At this moment, under motor 13 driving effects, drive dancing roll 15 by belt and belt pulley and rotate.Like this, realized just when core paper is sent on the path of contact of upper and lower corrugation roller 5,4 that facial tissue conveying mechanism 7 begins to carry facial tissue to the path of contact place of lower corrugated roller 4 pressure rolls 6 simultaneously.

Can guarantee fully that on structural design the front end at the front end of in type corrugating medium and facial tissue arrives the path of contact of lower corrugated roller 4 and pressure roll 6 simultaneously.Like this, utilize the structure of the utility model device, can avoid corrugating medium and the bonding inconsistent phenomenon of facial tissue effectively, can maximally utilise raw material paper like this, improve yield rate.

Self-explantoryly be, when the tail end of core paper is passed by when going up the path of contact of lower corrugated roller 5,4, the above-mentioned power of upwards pushing upper corrugated roller 5 open disappears, framework 10 resets under the effect of spring 28, and the switch that furthers disconnects, after electromagnet 18 outages, lever dolly 14 resets under the effect of counterweight 17, motor 13 remains in operation simultaneously, so just stops the conveying of next face root, finishes a working cycles.

Because the structure of rubber-coated mechanism 2 is intended mutually with prior art, therefore in above-mentioned description, also it is not described the course of work.

From the description of the said structure and the course of work, be not difficult to find out, core paper and facial tissue for different-thickness, the utility model device all adopt the spring governor motion regulate and each roller between pressure, so structurally simplified greatly, and it is also more convenient to regulate operation, simultaneously than the existing gas or the governor motion that surges, the most significant advantage is that cost reduces greatly, be convenient to maintenance, easy to operate, and also the quality of corrugated paper finished product is guaranteed.
