Description
Technical Field
The invention belongs to the technical field of low-grammage paper production, and particularly discloses a production system of high-quality natural-color low-grammage paper.
Background
Low-basis weight paper is more and more popular in various industries because low-basis weight paper has a low basis weight, and the lower the basis weight of paper, the less environmental impact and the more comfortable use of paper. With the constant acceleration of knowledge economy and the development trend of recycling economy, the demand of low-gram-weight paper is higher and higher, especially for high-quality natural-color low-gram-weight paper.
In the production process of low-gram-weight paper, the formed paper needs to be dewatered and dried, which is usually completed by adopting a drying system, and the existing drying system generally adopts a hot air type drying technology. The hot air type drying technology is applied to drying of low-gram-weight paper, and due to the fact that hot air is adopted to directly dry the paper, for the high-quality natural-color low-gram-weight paper, the hot air direct blowing can cause uneven shrinkage and damage to color and quality. Meanwhile, the energy consumption is high, the heat utilization efficiency is low, and the environmental pollution is easily caused.
Disclosure of Invention
The invention aims to provide a production system of high-quality natural color low-grammage paper, which aims to solve the problem that the color and the quality are damaged when a hot air type drying technology is adopted to dry the high-quality natural color low-grammage paper.
In order to achieve the purpose, the basic scheme of the invention is as follows: a production system of high-quality natural-color low-gram-weight paper comprises a drying box, a tray rack and an exhaust drying mechanism, wherein a box door is arranged on the drying box, and a heat-insulating layer is arranged on the drying box; the exhaust drying mechanism and the tray rack are arranged in a drying box, and a dehumidifying unit is arranged in the drying box; the exhaust drying mechanism comprises an exhaust fan, a heating plate and a plurality of rows of exhaust pipes, wherein the exhaust fan is connected with the plurality of rows of exhaust pipes, the heating plate is positioned between the exhaust fan and the exhaust pipes, and a plurality of through holes are formed in two sides of the exhaust pipes in the horizontal direction; the tray frame is provided with a plurality of layers of tray frames, and the tray frames and the exhaust pipes are arranged in a staggered mode.
The working principle of the basic scheme is as follows: the system is used for drying and producing high-quality natural-color low-gram-weight paper in the production process, after the formed paper is placed into the tray, the tray can be placed into the tray frame, the box door is closed, and the air exhaust drying mechanism and the dehumidifying unit are started. After the stoving unit that airs exhaust starts, the air exhauster is sent into the stoving incasement with wind, and the hot plate heats the wind of sending into the stoving case, discharges through the through-hole of exhaust pipe both sides again, because the through-hole is located the exhaust pipe horizontal direction, and the crisscross setting of tray frame and exhaust pipe for hot-blast high quality true qualities low gram weight paper that can not be to on the tray directly blows, but makes high quality true qualities low gram weight paper on the tray be in there is hot-blast environment. Hot-blast wet unit discharge that still can advance makes the incasement of drying form a heated air circulation state, then hot-blast high-quality true qualities low gram weight paper that can not directly be to on the tray is dried again, and then makes high-quality true qualities low gram weight paper on the tray can not lead to the shrink inhomogeneous because of hot-blast straight blow, and colour and quality are impaired. The heat preservation can preserve the heat of stoving incasement portion and not run off because of the environment, and then reduces the loss of energy consumption, improves heat utilization efficiency.
The beneficial effect of this basic scheme lies in:
1. although this system is dried high quality true qualities low gram weight paper through hot-blast, hot-blast can not directly weather to high quality true qualities low gram weight paper among the drying process, just lets high quality true qualities low gram weight paper carry out the environment that is in heated air circulation and is in, and then prevents that high quality true qualities low gram weight paper from carrying out the shrink inhomogeneous, the impaired problem of colour and quality that leads to because of hot-blast directly blowing effect.
2. This system has effectively prevented the heat loss of stoving incasement through the cooperation of heat preservation and stoving mechanism of airing exhaust, and then has reduced the loss of energy consumption, has improved thermal utilization efficiency.
Compared with the prior art, the system can ensure that the color and the quality of the low-gram-weight paper are not damaged when the low-gram-weight paper with high quality and natural color is dried, and can reduce the loss of energy consumption.
Furthermore, the through-holes are evenly arranged at intervals, the cross sections of the through-holes are trumpet-shaped, and the large-diameter ends of the through-holes face outwards.
The shape of through-hole can reduce hot-blast temperature, and the setting of through-hole can be more even carry out the stoving effect to the low gram weight paper in the tray.
Furthermore, the dehumidifying unit comprises two dehumidifiers, and the dehumidifiers are arranged on two side faces of the drying box, which are adjacent to the box door.
The dehumidifier is arranged in such a way, so that the air in the drying box flows more uniformly, and the drying effect of the low-gram-weight paper is better.
Further, a plurality of telescopic rods are arranged in the drying box, the box door is fixedly connected with the telescopic rods, and the tray rack is fixed with the box door.
The chamber door passes through the telescopic link to be connected with the stoving case, and opening and closing of chamber door is through the flexible control of telescopic link, and the chamber door is convenient for use with the fixed tray frame of chamber door after opening to it is more convenient to make this system use.
Further, the inside temperature and humidity sensor that is equipped with of stoving incasement portion, temperature and humidity sensor links with dehumidifier and hot plate electricity respectively.
Carry out the close control through temperature and humidity sensor to the temperature and the humidity of stoving incasement, further make the stoving in-box low gram weight paper's stoving process environment better, and then keep the production effect of low gram weight paper better.
Further, a moving mechanism is arranged on the box door and drives the tray rack to move in a reciprocating mode.
The moving mechanism enables the tray frame to do reciprocating motion circularly, so that the drying process of the low-gram-weight paper in the tray is quicker.
Further, an oval sliding groove is formed in the box door, a sliding block is arranged in the sliding groove, the tray frame is fixedly connected with the sliding block, and the sliding block is driven by the moving mechanism to move in the sliding groove.
The sliding block drives the tray frame to continuously move in an oval shape, so that the moving process of the tray frame is stable, the drying process of the low-gram-weight paper is kept, the drying efficiency is improved, and the quality is not influenced.
Further, the moving mechanism comprises a motor and a conveyor belt, the motor drives the conveyor belt to transmit, and the conveyor belt is fixed with the sliding block.
The design and the manufacture of the moving mechanism are convenient.
