2.5 to fluid devices

Low- echelon type sizing machine is usually installed at both ends of each piece of the roller surface Block rubber, plastic material so that the pool to maintain a certain level , when the speed increased, the transfer roller And accelerating the speed of the fast moving paper web produced by the fluid force is too large, so that the glue will Breaking the surface of the material spilled pool and nip this material pool turbulent and nip interference Resulting in uneven lateral amount of glue .Size press on high speed , the corresponding increase in the diameter of the sizing roller , there Strength will compensate for the larger flow , while the roll diameter increases correspondingly reduced glue Acceleration forces , roller end faces longer set block rubber, glue from the glue tube is continuous Flowing material pool. Excess glue applied to flow directly into the roller end face to plastic tray. Through Filtered through the sieve into the next cycle of the loop glue , glue effectively prevent turbulence And jump plasma phenomena , ensuring high-speed operation under uniform sizing .On. Under sizing each have a roll to the upper tube. In the width direction of the paper machine A plurality of fluid nozzles average to evenly apply glue supply. By setting a Liquid branch pipe and ball to adjust to the fluid manifold fluid flow. And the addition of overhaul Cleaned with cleaning pipes (normally closed during normal operation) and sewage valves, convenient tube Road cleansing, to further ensure the quality of sizing. 

2.6 wiper edge 

Sizing the operating side of the roll, the roll drive side end surface, a coil spring-Compression wiper edge (see Figure 2.6). Roller rotation prevents the glue from the process of applying Roll end splash. Also features lubrication pipes, glue applied at both ends to prevent the roller sessile The glue is applied while increasing the effect of scraping off, in order to recover from the edge of the wiper scrape Liquid, sizing rollers at both ends and a drain cover.

2.7 Citation roller moving means 

To ensure the quality of sizing to prevent wrinkles in the paper entering the nip and the sizing Offset, reducing the occurrence of breaks. Into leading roll size press with threading Roller moving means (see Figure 2.7), before and after the movement amount is 50m m, according to the machine Operation be adjusted to the best position. Be adjusted by adjusting the ratchet wrench Whole, and the operating side and the drive side to the same time, the adjustment is completed with a locking screw locks

2.8 Given location. Zhisheng mobile devices 

After threading is complete, if Zhisheng has been in the lead position sizing paper nip SRE will easily be applied glue dirty. Therefore set Zhisheng mobile device (see Figure 2.8). After the lead when threading through the nip of the paper Zhisheng, the paper cited the success through the cylinder Piston movement to the position away from the nip portion, the paper threading back off again Back, alternately action

2.9 breaks the whole device

In order to protect the plastic surface , to prevent the continued operation of the plastic surface after some breaks Hazards, increased whole lot of breaks devices. This device is a web break detector detects Send a signal to the PLC after the whole paper break automatically breaks . To ensure the paper is cut Mouth and reduce loss of paper , velocity and timing of cutting knife is important .

2.10 tail threading device

To achieve the former cadres to smooth r cited paper sizing unit , equipped with advanced Tail threading apparatus ( see Figure 2.10 ) . When former cadres to lead the paper sizing machines last F paper prepared by Head down to just the dryer has cited paper pulper button, the blade below Hair board started cited paper was blown down in the pulper . Blowing down process And when you see the cited paper accurately located in the middle of a hair panel , press the cited paper cut Arab Spring . Cut month lifted, threading engagement with the end of the fixed guide plate hair cutter, paper is Cut , while down from the hair dryer cited paper plates were blown sizing guide Machine initiative Zhisheng arranged Zhisheng folder area, and then by Zhisheng lead slip grip Continue to send forward . Then automatically stop tail threading cardboard 施涂机英文文献和中文翻译(5):http://www.751com.cn/fanyi/lunwen_53234.html
