(1) The working process of the stable material forming system 1 comprises the following steps:

the preparation of the material mixing comprises the steps of mixing gypsum powder, glass fiber and solid additives according to a proportion and accurately proportioning, then conveying the mixture into a gypsum bin 101, connecting a water inlet pipe 107 with a water supply pipe, and connecting a liquid additive bin 108 with a liquid additive supply port.

The process of initially installing the fiber cloth comprises the following steps: the upper fiber cloth 113 installed on the upper fiber cloth rack 129 sequentially passes through the upper deviation rectifying machine 112, the lower side of the leveling roller shaft 124 and the lower surface of the upper forming belt 114 from left to right, and the lower fiber cloth 127 installed on the lower fiber cloth rack 128 sequentially passes through the lower deviation rectifying machine 126 and the inner surface of the groove of the lower forming belt 123 from left to right; because the flexibility of the fiber cloth is far higher than that of the facing paper, the fiber cloth is easy to deviate during conveying, and therefore, a deviation correcting machine is required to be arranged in high-speed production equipment.

Gypsum materials are mixed into slurry, a lifter 105 lifts the mixed gypsum powder in a gypsum bin 101 into a transverse conveyor 103, the gypsum powder is firstly transported into a hopper of an electronic scale 104, and if the storage of the hopper is full, the excessive gypsum powder flows into a return pipe 102 through a left port of the transverse conveyor 103 and then flows back into the gypsum bin 101; the electronic scale 104 feeds and conveys the conveyor 106 into the stirrer 109 in a metered amount, the liquid additive and water flow into the stirrer 109 in a metered amount through a metering and conveying valve, and the slurry is uniformly stirred into gypsum slurry, and the gypsum slurry flows onto a lower fiber cloth 113 on the inner surface of the groove of the lower molding belt 123 through a vibrating conveying pipe 110.

The vibrating conveying pipe 110 has the advantages that: each discharging hose 1101 is connected by adopting a transverse spring and a longitudinal spring, the discharging hose 1101 is kept vibrating under the action of a vibrating motor 1104, gypsum slurry in the hose can flow out quickly and sequentially, solidification and blockage caused by unsmooth local flow are avoided, a hard pipe head 1106 is arranged at the head of the discharging hose 1101 and is fixed by a fixing frame 1105, and the stability of the gypsum slurry when flowing out of the hard pipe head 1106 is ensured. In the conventional gypsum board molding process, a station is required to manually level the gypsum slurry and knead the gypsum slurry output pipe at fixed time to prevent local solidification.

The fiber gypsum board is molded, gypsum slurry flows onto a lower fiber cloth 127 on the inner surface of a groove of a lower molding belt 123, a lower belt shaft 120 and an upper belt shaft 116 rotate to respectively drive the lower molding belt 123 and the upper molding belt 114 to move, and then drive the lower fiber cloth 127 and the upper fiber cloth 113 to move rightwards, when the gypsum slurry passes through a leveling roller shaft 124, the gypsum slurry is primarily flattened, and then passes through the lower surface of an upper molding belt 114 below the lower plane of a molding pressing plate 115, the gypsum board with required thickness is extruded in the groove of the lower molding belt 123, the upper fiber cloth 113 and the lower fiber cloth 127 are respectively pressed into the upper surface and the lower surface of the gypsum board, at the moment, the gypsum slurry starts to be initially set, the fiber cloth is adhered by the initially set gypsum slurry, and the relative position of the fiber cloth is fixed; after passing through the lower planar area of the forming platen 115, the gypsum board is separated from the upper forming belt 114, transported by the lower forming belt 123 onto the drive roller 119 and separated from the lower forming belt 123, and the gypsum board is transported by the drive roller 119 to the next station; the driving end of the lower belt shaft 120 is disposed on the lower belt shaft on the right side, and the driving end of the upper belt shaft 116 is disposed on the upper belt shaft on the right side, so that the lower forming belt 123 and the upper forming belt 114 respectively form a tensile scraping effect on the lower fiber cloth 127 and the upper fiber cloth 113, and the fiber cloth stretches and is flat in the high-speed forming process.

The upper fiber cloth 113 is arranged below the leveling roller 124, the lower end part of the leveling roller 124 stretches into the U-shaped groove of the lower forming belt 123, the end surfaces of the two sides of the leveling roller 124 are tightly contacted with the two side edges of the U-shaped groove, the leveling roller 124 is prevented from being directly contacted with gypsum slurry, and the gypsum slurry is solidified and adhered on the leveling roller 124 and is not easy to clean; the rotational linear speed of the leveling roller shaft 124 does not exceed the horizontal speed of the lower molding belt 123, and the tightening and leveling of the upper fabric 113 can be ensured.

The groove group is arranged on the lower surface of the forming pressing plate 115, the contact area between the lower surface and the U-shaped surface of the upper forming belt 114 is reduced, the friction force during relative movement is reduced, vibration cannot be generated due to overlarge friction force after the speed of the forming belt is improved, meanwhile, the upper forming belt 114 has certain toughness and rigidity, when the groove group of the forming pressing plate 115 is arranged densely, the vertical pressure on the upper surface of the upper forming belt 114 on the lower surface is equally divided by the toughness, and therefore, the uneven effect cannot be formed on the upper surface of the gypsum board.

The gypsum board is extrusion in the enclosure space in the recess of lower shaping belt 123, avoid the gypsum thick liquid to follow the excessive of side, go up the U type structure of shaping belt 114, the area of contact of the both sides limit of going up shaping belt 114 and the U type side of shaping belt 123 down has been increased, further anti-overflow effect has been increased, thereby the required cleaning device after the gypsum thick liquid overflows in the traditional shaping scheme has been saved, guarantee simultaneously that the U type groove of the internal surface of last shaping belt 114 can closely cooperate with the lower bottom surface and both sides limit of shaping clamp plate 115, do not take place the lateral deviation, the internal surface U type groove of last shaping belt 114 cooperatees with the step structure of last belt axle 116, do not take place lateral displacement.

The vertical height of the molding press 115 can be adjusted by the press fixing frame 122, so that the thickness of the molding gypsum board can be adjusted, and the tension roller 117 realizes the tension effect on the upper molding belt 123 in thickness adjustment.

(2) The working process of the preheating curing system 2 comprises the following steps:

in the traditional gypsum board production process, after the gypsum board is molded by a molding machine, the gypsum board is conveyed to a cutting system for fixed-length cutting, but in high-speed production equipment, the gypsum board conveying speed is greatly increased, when the gypsum board reaches the cutting system, solidification is insufficient, the cutting effect is poor, and the gypsum board can be fully solidified only by lengthening a conveying line to cause the overlength of a production line, so that in the fiber gypsum board high-speed production line, a preheating solidification process is designed, a preheating solidification system 2 is developed, a heat regenerating device is designed in a drying and heat regenerating utilization system 4, and the natural solidification process of the gypsum board before cutting is changed into a heating solidification and ultraviolet solidification process, thereby greatly shortening the length of the production line.

The fiber gypsum board is conveyed into the insulation box 201 by the driving roll shaft 119, the first heater 202 on the inner wall of the box is used for promoting the radiation heating and solidification of the gypsum board, the ultraviolet lamp 203 is used for irradiating the gypsum board and promoting the solidification of UV glue, the air inlet pipe 205 is used for blowing dry hot air to blow the gypsum board to dry and thermally cure the gypsum board, under the action of three modes, the gypsum board can be quickly solidified in the insulation box 201, and then the gypsum board is conveyed to the next station for sizing and cutting through the driving roll shaft 119. The first heater 202 is preferably a radiation type heater because if an air conduction type heater is selected, the generated heat is easily blown away by dry hot air blown by the air inlet pipe 205, so that the heat loss is larger, the UV irradiation curing is a unique innovation of the process, the traditional paper gypsum board is shielded by the protective paper, the ultraviolet light cannot be cured by the UV irradiation, the surface of the fiber gypsum board is covered fiber cloth, the fiber is provided with a certain gap, and the fiber cloth is pressed into the surface of the gypsum board, the curing speed is very high after the UV glue is irradiated by the ultraviolet lamp, and the air inlet pipe 205 is blown dry by hot air to further accelerate the curing of the gypsum board.

(3) The working process of the double-station follow-up cutting system 3 comprises the following steps:

the toughness and elasticity of the fiber cloth are stronger, a knife cutting process of a traditional paper-surface gypsum board is adopted, the cutting surface is rough and easy to damage, and therefore a follow-up sawing mode is adopted, but the cutting speed of the follow-up sawing process is slower, and the quick return repeated cutting of the follow-up cutting device after the cutting of a single gypsum board is finished cannot be guaranteed in high-speed production, so that a double-station follow-up cutting process is developed, two gypsum boards are sawed in a follow-up mode simultaneously, and sawing strokes are completed once for every two sawing lengths of the gypsum boards, namely, the reciprocating stroke of the follow-up cutting device is the same as the stroke of the single-station follow-up cutting, so that the quick cutting in high-speed production is realized.

The fiber gypsum board is conveyed onto a left driven roller 304 on a sliding plate 303 from a preheating curing system 2, sequentially passes through a first positioning roller 305, a right driven roller 304 and a right driving roller 119, the distance between the left driven roller and the right driven roller is the cutting dimension length of one gypsum board, when the distance between the right end of the gypsum board and a cutting device 308 on the right side of the sliding plate 303 reaches a cutting length, the sliding plate 303 moves along a track 302 and the gypsum board at the same speed in the same direction under the driving of a servo motor 307, the two cutting devices 308 start to transversely saw along a transverse track 3082, the single cutting time does not exceed the travel time of the sliding plate 303 from the left end to the right end along the track 302, the travel distance of the sliding plate 303 does not exceed the distance between the left side of a rectangular hole in the sliding plate 303 and the left side of a first positioning wheel 306, otherwise, the sliding plate 303 interferes with the first positioning wheel 306, after the cutting is finished, the sliding plate 308 is reset, the fiber gypsum board continues to move, and the reset time of the sliding plate 303 does not exceed the two-pass sawing lengths required by the conveying of the gypsum board, so that the sawing is repeated.

When the sliding plate 303 and the fiber gypsum board move in the same direction and at the same speed, the passive roller 304 plays a supporting role on the fiber gypsum board, and when the sliding plate 303 returns to the original position, the passive roller 304 and the fiber gypsum board are in rolling connection, so that the lower surface of the gypsum board is not damaged.

The best effect is that the stable synchronization between the plasterboard and the slide 303 is kept constant and the position of the plasterboard is fixed, but the clamping force required for the position fixing is not required to be too large because the plasterboard is an integral body before cutting and the fiber plasterboard is heavy. The first positioning roller 305 is connected with a device for driving rotation, is directly fixed on the cutting area bracket 301, has the same linear speed with the linear speed of the driving roller shaft 119, can realize the transportation of the plasterboard, is positioned in the steps in the first positioning roller 305, realizes the transverse position limitation of the plasterboard, and is provided with a first positioning wheel 306 at the upper end of the first positioning roller 305, and the plasterboard is fixed in position in the vertical direction, thus ensuring the stability of the plasterboard during cutting. The small gap is reserved between the lower surface of the first positioning wheel 306 and the upper surface of the gypsum board, because the first positioning roller 305 and the second positioning roller 310 have certain cylindricity errors, if the first positioning wheel 306 and the gypsum board are in close contact, the cylindricity errors at high speed can generate vibration effects on the gypsum board, the gap is not reserved, the surface of the gypsum board is not damaged, therefore, the small gap distance is set to be equal to the cylindricity error value, the first positioning wheel 306 can generate certain clamping effects on the gypsum board through the cylindricity errors, the upper surface and the lower surface of the gypsum board are not damaged, the clamping principle of the second positioning roller 310 and the second positioning wheel 309 is the same, and stable positioning of the gypsum board is realized.

In the cutting device 308, if the saw blade 3085 is a nondirectional toothless saw blade, the coupling mechanism 3084 is a straight connecting rod and is responsible for coupling the driving wheel 3083 and the saw blade 3085, and the saw blade 3085 can cut in a return stroke without rotating 180 degrees after cutting in a single pass; if the saw blade 3085 is a toothed saw blade with directivity, the coupling mechanism 3084 is a torsional structure capable of rotating 180 degrees to couple the driving wheel 3083 and the saw blade 3085, and when the saw blade 3085 is twisted 180 degrees after cutting in one pass, the saw blade is cut in a return stroke to adapt to the directivity of the toothed saw blade, and the coupling mechanism 3084 is a common coupling piece with a rotating function, but the coupling mechanism is required to have a power steering function. Saw blade 3085 is vertically positioned between two passive rollers 304 without sawing slide 303.

(4) The working process of the drying and backheating utilization system 4 is as follows:

the principle of the closed structure of the drying box 401 is that the inlet and the outlet of each layer in the drying box 401 are provided with a soft baffle 412 and a hard baffle 413 which are connected in a staggered manner, each layer is in a closed state, the whole drying box 401 is in a closed state, when the gypsum board is at the inlet or the outlet, the soft baffle 412 is lapped on the upper surface of the gypsum board, the height of the hard baffle 413 is equal to the height of the conveying shaft 411, and the drying box 401 is also in a closed state.

In the hot air circulation drying process, the air suction fan 403 sucks out the air in the drying box 401 from the air outlet pipe 402, a large amount of water vapor is contained in the air, when the air passes through the circulating air main pipe 408, the density of the water vapor is lower, the water vapor enters the moisture discharging pipe 404, the dried air is heated by the second heater 409 and is sent back into the drying box 401 through the air inlet pipe 410, so that hot air circulation drying is realized, and the drying hot air is more favorable for drying wet gypsum boards.

In the conventional drying process, the hot steam entering the moisture discharging pipe 404 is wasted, the hot steam exchanges heat by the heat exchanger 406, and the heat after the heat exchange is blown into the heat preservation box 201 in the form of dry hot air through the hot return air output pipe 405 and the air inlet pipe 205 of the preheating solidification system 2, so that the heat recovery and reutilization are realized.

The advantages are that: the whole set of production equipment has compact structure, high production efficiency, strong automation degree, stable production process and high productivity; the processing technology is novel, scientific and reasonable, and is very suitable for high-speed manufacture of fiber gypsum boards; the main raw material gypsum powder is processed by phosphogypsum serving as an industrial tail material of a phosphate fertilizer plant or sulphur gypsum serving as an industrial tail material of a power plant, so that the waste utilization is realized, and the production cost of the fiber gypsum board is greatly reduced.
