Description
Technical field
The present invention relates to a kind of corrugated paper board production line drying unit, be applied to belong to light industry and machinery and energy-saving field on the corrugation drying system of corrugated paper board production line.
Background technology
Traditional corrugated paper board production line drying unit, by the oven dry plate, heating platen or pressure roller are formed, and are clipped in the corrugation on the conveyer belt, by oven dry plate working face heat are provided, and transmit heat and give corrugation, play need of stoving.
Corrugated paper production line uses has had very long history so far, generally presses with pressure roller at first above the oven dry plate, and developing into now with the heating power pressing plate increases contact area, improves heat-transfer effect.The heating power pressing plate is used in corrugated paper board production line oven dry portion, replaces traditional pressure roller, and it is with being intended to: 1. the pressure roller under the traditional form causes the drying-plate concentrated wear easily.Article one, new board production is used after the 1-2, can find and the pressure roller position, and the wearing and tearing of hot plate amount can reach 1mm～2mm, our transformed production line, and the hot plate that has wearing and tearing reach more than the 4mm deeply.Like this, during through hot plate heating corrugated board,, influenced the moulding of cardboard, also reduced the speed of production line simultaneously, be unfavorable for that cardboard is bonding because the running orbit of cardboard is existing " S " type.2. the heating power pressing plate is compared with pressure roller, adopts the pressure roller compacting, and the contact area of cardboard and hot plate is little; And adopt the heating power pressing plate to suppress the sail band; Can improve the contact area of cardboard and hot plate greatly, guarantee cardboard forming time institute calorific requirement, particularly the heat of the urgent need of oven dry portion front cardboard setting.3. adopt the heating power pressing plate, can overcome cardboard office plate and the hot plate loose contact that the thermal deformation owing to drying-plate causes influences exchange heat.4. owing to the height of heating power pressing plate is realized through automatic control, when producing the cardboard of different-thickness, the different numbers of plies, can artificially control automatically, guarantee the different condition of equivalent thickness of the thickness of cardboard, particularly width through measuring.
Any material all has the characteristic of expanding with heat and contract with cold, when corrugated board through hot plate oven dry the time can take away great amount of heat, make at the bottom of the hot plate inconsistent with the temperature of face.Top temperature is low, and hot drying-plate is with regard to concave deformation, and especially first to the 5th variation is the most obvious.Speed is fast more, and the heat of taking away is many more, is out of shape big more.In addition, traditional gravity pressure roller is a straight line, is the line contact, can be not crooked along with the hot plate distortion.Like this middle part just press less than, and both sides are pressed overweightly, cause to come unstuck, bubbles, fit in the middle of the cardboard bad etc., the corrugation shape on certain both sides is crushed.In addition, its heat transfer efficiency is low, will come unstuck because of the cardboard shortage of heat if the speed of a motor vehicle is too fast, and it is bad to cause fitting.Because the cylinder last item is what disperse to install, weight is difficult for adjustment, is easy to flatten the stupefied shape of corrugated board and stupefied phenomenon occurs down, and the cardboard of producing also can crooked out-of-flatness, more difficult adjustment when especially single corrugation and double-layer corrugated cardboard conversion.Change the gravity pressure roller into heating platen, set up the one group of heating platen that can control up-down separately on every block of hot plate separately, every group of heating platen can both be controlled separately.Can freely select according to the different speed of a motor vehicle, different temperatures, can address the above problem preferably.
But to the oven dry plate, the general power of only considering to improve heat source can improve speed; Do not have to consider how to utilize the limited energy, reduce reactive loss and enhance productivity.
The concave deformation that oven dry plate owing to expand with heat and contract with cold is caused not find to have to improve from the oven dry plate structure and overcomes.
Oven dry plate lower surface 160-180 ℃ of high-temperature metal surface is in naked state according to investigations in decades always, the heat radiation energy consumption with the energy that contacts air transmitted is belonged to reactive loss, and caused the workshop temperature too high.Soon the attached carton factory of rugged printing of Fuyang, Zhejiang day of opening adopts the comparatively novel equipment of domestic corrugated paper production line equipment Jingshan Light Industry Machinery Co., Ltd., Hubei of leading enterprise, and the inventor finds also recently that oven dry plate lower surface is exposed so far and contacts with air; It is more famous with management that Fuyang, Zhejiang one ring is packaged in the carton industry of Hangzhou its technology, and the corrugated paper production line oven dry plate lower surface of its import is exposed equally to be contacted with air.Corrugated paper production line oven dry plate lower surface is exposed to be corrugated paper production line way always, forms a kind of inertial thinking, and the instrument factory technical staff does not generally have concern to have very big energy waste here.
The workshop temperature was generally higher when corrugated paper board production line was produced, and especially when summer, weather was hot, working environment was very abominable, does not generally solve this difficult problem so far, and operator's work is very arduous.
