Description

Forming method of reinforced fiber board blank

Technical Field

The invention relates to the technical field of reinforced fiber board processing, in particular to a forming method of a reinforced fiber board blank.

Background

Currently, the application amount of the reinforced fiber board is quite large. However, the conventional production method has the following disadvantages: the slabs produced by the traditional production process have different blank thicknesses, the thickness deviation generally exceeds the standard value of the industry, the flatness also has larger deviation, and the thickness of all the slabs is difficult to control within the allowable standard deviation range even if the slabs are produced in the same batch; steel templates are required to be used for stacking and separating the slabs, and a large number of steel templates, trolleys for transporting the templates, steel template release agents or lubricants and the like are occupied; because the slab thickness is different when the slab is manufactured, the slab is asymmetric left, right or has larger flatness deviation, even if the whole stacking slab is compacted and leveled by pressurizing through a press, the thickness and the size can not be basically unified all the time due to the large and small deviation of the slab, and the flatness can only be improved to some extent; the steel templates are used for separating the stacked plate blanks to prevent the adhesion between the plate blanks, so that the smooth water drainage through the steel templates is avoided when the plate blanks are pressed by a press, the pressing speed is low (the plate blanks are too fast to be drained smoothly, so that slurry is burst and splashed to be damaged), and the time consumption is long; the pressed plate blank needs to be pre-cured for a long time, and the plate blank can be easily demoulded (the plate blank is separated from the steel template) after being dried and hardened; the subsequent process needs to remove the material and fix the thickness of the plate blank by a sander, so that a large amount of waste materials are recycled, the production quality of the plate blank is indirectly influenced, and a large amount of manpower, material resources and equipment investment are wasted; reserving enough size allowance for cutting, edging and correcting the length and width of the produced plate blank; the flatness and smoothness of the produced plate surface are relatively insufficient; the plate blank cutting adopts a pure transmission mode of a roller shaft conveyer belt, and the conveyer belt is often deviated left and right, so that the diagonal line of the plate blank is unstable, the deviation is large, and manual adjustment is needed; the slab production non-continuous operation generally comprises the steps of cutting vertically and horizontally and stacking (each slab needs to be separated by a template) after a primary slab is produced, then conveying the primary slab to a press by a trolley in a rail conveying mode, then conveying the whole stacked slab into the press by a traction device for pressing, pulling out the trolley of the whole stacked slab by the traction device after pressing is finished, then placing the trolley for pre-curing to wait for slab condensation and drying, separating the slab from a steel template and stacking the slab by a stripper, and finally conveying the slab into a still kettle for high-temperature and high-pressure steam curing, wherein the whole process is complex and complicated in flow, and a large amount of manpower and material resources are consumed.

The upper extrusion roller can do vertical reciprocating motion under the driving of the vertical adjusting component; and the upper extrusion roller is positioned above the lower extrusion roller, so that the distance between the upper extrusion roller and the lower extrusion roller can be adjusted through the vertical adjusting assembly, and the extrusion mechanism can be used for extruding slabs with different thicknesses, thereby effectively improving the application range of the thickness fixing device. Because last squeeze roll and last brush roller all set up on vertical adjusting part, and go up squeeze roll and last brush roller homoenergetic and be vertical reciprocating motion under vertical adjusting part's drive, enable like this and go up the reciprocating of squeeze roll and last brush roller and keep synchronous, this interval that just can avoid going up between squeeze roll and the last brush roller changes to it has good clean effect all the time to enable to go up the brush roller. Because the left side edge of the bottom surface of the covering cover is provided with the accommodating cavity opening, and the right lower cavity wall of the accommodating cavity opening is provided with the material receiving groove body; then, because the upper part of the upper squeeze roll and the upper brush roll are positioned in the accommodating cavity opening, the material receiving groove body is positioned below the right circumferential surface of the upper squeeze roll, and the material receiving groove body is positioned above the right side of the lower circumferential surface of the upper squeeze roll, the upper squeeze roll and the upper brush roll can rotate anticlockwise in the use process, and therefore moisture and raw materials thrown from the upper squeeze roll and the upper brush roll can splash onto the right cavity wall of the accommodating cavity opening; in the process that the water and the raw materials flow downwards, the material receiving groove body can just receive the water and the raw materials to prevent the water and the raw materials from flowing downwards continuously, so that the water and the raw materials can be prevented from dropping on the extruded plate blank, and the high-quality plate blank can be conveniently extruded; and the condition that moisture or raw materials splash at will everywhere can be avoided like this to avoid the environment in workshop to receive the pollution. The structure of the cover is very simple, which can facilitate the manufacture of the fixed-thickness extrusion device of the reinforced fiber board blank. Through making the upper brush roller be longitudinal extension to make the circumferential surface of upper brush roller and the circumferential surface of last squeeze roll contact, can play fine cleaning action to the circumferential surface of last squeeze roll like this, thereby help improving the clear quality of last squeeze roll, and then help improving the extrusion quality of slab. Through making lower brush roller be longitudinal extension to make the circumferential surface of brush roller down contact with the circumferential surface of squeeze roll down, can play fine cleaning action to the circumferential surface of squeeze roll down like this, thereby help improving the clear quality of squeeze roll down, and then help improving the extrusion quality of slab. Through the arrangement of the water receiving tank body, the water receiving tank body is positioned below the lower extrusion roller, so that when water is extruded out of the plate blank, the water can be collected by the water receiving tank body, and the environment of a workshop is prevented from being polluted by the water; and the lower part of the lower squeeze roller and the lower brush roller are positioned in the water receiving tank body, so that the probability of splashing of water and raw materials can be greatly reduced, and the environment of a workshop can be prevented from being polluted. Through the setting of each transition roller axle to make each transition roller axle arrange side by side under two between the squeeze roll, can play fine bearing effect to the slab like this when the slab passes through between two extrusion devices, the probability that deformation appears in this slab that can significantly reduce, thereby can further improve the processingquality of slab. By arranging the two extrusion mechanisms on the second frame horizontally side by side, continuous extrusion is realized, and the extrusion quality of the plate blank is improved. Through the setting of vertical cutting device, can play the purpose of vertical cutting slab, be convenient for like this when the blanking, produce big slab earlier, then obtain the billet of suitable size through the cutting, can save the blanking process of a certain amount like this to the enterprise of being convenient for improves the production efficiency of slab according to the needs of production at any time. By adopting the electromagnetic adsorption die head and the iron pressing plate, the iron pressing plate can be adsorbed on the electromagnetic adsorption die head after being electrified; and after the outage, then can very conveniently dismantle the iron clamp plate from the electromagnetism adsorption die head, this helps improving the iron clamp plate separation and maintains the operation convenience to help improving the convenience of the maintenance of iron clamp plate. The fluorine coating or the die-casting wear-resistant non-stick silica gel is sprayed on the surface of the iron pressing plate, so that the iron pressing plate has an anti-sticking effect, and the iron pressing plate can be easily separated after the plate blank is pressed, so that the surface of the plate blank is smooth and is not peeled and fluffed, and the production quality of the plate blank is improved. Through the arrangement of the drainage trough plate and the drainage support filter plate, moisture extruded on the slab can be smoothly discharged when the slab is processed, so that the density and the appearance quality of the slab are prevented from being influenced, the slab surface is enabled to be finer, smoother and smoother, the processing quality of the slab is further improved, and the production efficiency of the slab can be greatly improved. By using stainless steel for the hydrophobic support filter plate, it can be prevented from being magnetically adsorbed, which contributes to improvement in reliability of the pressing action of the platen device. High-pressure water can be sprayed to the polyester spiral conveying mesh belt through the high-pressure water spraying head, so that a very good cleaning effect can be achieved on the polyester spiral conveying mesh belt, and raw materials or impurities are prevented from remaining on the polyester spiral conveying mesh belt; the vacuum water suction head can suck the moisture on the polyester spiral conveying mesh belt so as to avoid the condition that the moisture on the washed polyester spiral conveying mesh belt is excessive, so that the condition that the plate blank is excessively wet can be avoided; this contributes to an improved production quality of the slab. Through the setting of absorption cylinder, can play the purpose of upwards holding the slab to enable the slab to break away from polyester spiral conveying mesh belt well, this stability that helps improving the slab and carry. Through the setting of horizontal cutting device, can play vertically to cut about the slab to can be used to the front and back side of cutting the slab, can reach the purpose of the repairment of slab like this, thereby help improving the machining precision of slab. Because slab bunching device includes fourth frame, fishplate bar conveyer belt, crane, vertical balladeur train, sucking disc, fishplate bar dolly, the vertical side cut subassembly in a left side, the vertical side cut subassembly in the right side, this slab bunching device can cut the side about the slab to and enable the slab and pile up at the fishplate bar dolly, the transport that the slab piled up neatly can also be convenient for, help improving the processingquality and the machining efficiency of slab like this. Through rim charge recovery unit's setting, can retrieve the slab left side that the slab front and back side, the left side that the left side vertical trimming subassembly cut that the horizontal cutting device cut got off, the slab right side that the right side vertical trimming subassembly cut got off to can avoid the waste of raw materials, this helps reducing manufacturing cost. By applying the forming method, the production of the plate blanks can be continuously carried out without stopping or transferring in other modes, and the whole processes from the manufacture of an initial blank (initial blank for short), the thickness control, the leveling compaction and the plate blank stacking are continuously and uninterruptedly operated, so that the systematization and integration of the plate blank forming are realized, and the plate blanks with smooth top surfaces and uniform sizes can be continuously and quickly produced. The devices used in the whole slab production process are all interdependent and are not independently separated, so that the production process is continuous, and the processing quality and the processing efficiency of the slab are improved. If the common reinforced fiber board is produced, the finished product can be basically obtained by high-temperature high-pressure steam curing and drying after the plate blank is formed, and sanding and edging can be omitted. Meanwhile, the stacked slabs are not required to be separated by a template and are directly conveyed to a steam curing process after being stacked, ground track transfer conveying and a large number of auxiliary production facilities and equipment are omitted, the control on the whole production cost and the production quality are greatly improved, and the production efficiency is greatly improved.

The cover 326 is also of a very simple construction which facilitates manufacture of the reinforcing fiberboard blank thickness-setting extrusion apparatus. By extending the upper brush roller 324 in the longitudinal direction and contacting the circumferential surface of the upper brush roller 324 with the circumferential surface of the upper squeeze roller 321, the circumferential surface of the upper squeeze roller 321 can be cleaned well, which contributes to improving the cleaning quality of the upper squeeze roller 321 and thus the squeezing quality of the slab.

The devices used in the whole slab production process are all interdependent and are not independently separated, so that the production process is continuous, and the processing quality and the processing efficiency of the slab are improved. If the common reinforced fiber board is produced, the finished product can be basically obtained by high-temperature high-pressure steam curing and drying after the plate blank is formed, and sanding and edging can be omitted. Meanwhile, the stacked slabs are not required to be separated by a template and are directly conveyed to a steam curing process after being stacked, ground track transfer conveying and a large number of auxiliary production facilities and equipment are omitted, the control on the whole production cost and the production quality are greatly improved, and the production efficiency is greatly improved.

As shown in fig. 2, the thick plate removing device 2 coordinates and controls the actions of the parts through a circuit control module on the existing plate blank forming system; wherein the inductive probe 25 and the first cylinder 27 are electrically connected with the circuit control module. A gap capable of ensuring the passage of a plate of normal thickness is reserved between the oscillating piece 24 and the fast conveyor belt 22; when the plate thickness is too large, the plate blank collides against the lower end of the swing member 24, thereby swinging the swing member 24; when the inductive probe 25 detects the swinging of the swinging piece 24, a corresponding signal is transmitted to the circuit control module; the first cylinder 27 is then retracted by the electronic control module to move the movable support plate 26 up and away from the blanking gap 29 by the first cylinder 27. When the thick plate blank moves to the blanking gap 29, the thick plate blank falls from the blanking gap 29 due to the loss of the limit of the movable supporting plate 26, and then falls on the double-helix crushing mechanism 28, so that the thick plate blank can be crushed, crushed materials are conveyed to the stirring tank through the corresponding conveying belt for stirring, and are returned to the batching system through the pump after being stirred, so that the thick plate blank can be reused, and the waste of raw materials can be avoided.

The common plate only needs a short time to be pressed and leveled; however, the high-density slab needs to be subjected to pressurization and pressure holding for a relatively long time, and the pressurization and pressure holding time depends on the process requirement.

The water content of the initial blank manufactured by the blank manufacturing device 1 is preferably controlled to be 28-30% so as to prevent the initial blank from being rolled and deformed relatively easily by the thickness setting device 3. The thickness is controlled within the deviation range of the process requirement, because the thickness is determined and compacted and leveled afterwards, and the specific reserved thickness compression amount is determined according to the production process requirement. In general, the compression amount of 0.0-1.0 mm is reserved in the thickness fixing treatment, so that the thickness of the plate blank treated by the thickness fixing device is ensured to be consistent from different thicknesses; 5-20% of compression amount needs to be reserved when the subsequent press is compacted and leveled; then, the total thickness of the produced primary blank is the thickness standard value plus the compacting and flattening compression amount (the thickness standard value is multiplied by (5-20%)) + the thickness setting treatment reserved amount. In addition, the thickness of the initial blank is allowed to have a deviation amount (the thickness of the thinnest part and the thickness of the thickest part of the initial blank) of 0-1 mm, and the total thickness of the initial blank is more than 1mm, the winding number of small material layers of the jet-laid plate making system or the amount of the jetted slurry can be controlled by adjusting, and the single-layer small material layer is controlled to be 0.2-1.0 mm/layer, so that the process requirement of the thickness of the initial blank is easily met. For example: the technological requirement is that a reinforced fiber board with the thickness of 10mm is produced, the compression amount of a press is 10%, the thickness value of a produced primary blank is controlled to be 10mm + 10 multiplied by 10% + 0.0-1.0 mm which is 11.0-12.0 mm, the compression amount is 1mm after the treatment of a thickness setting device 3, the thickness of the blank is 11.0mm, then the blank is compacted and flattened by the press, the compression ratio is about 10% or 1.0mm, the thickness of the final blank is controlled to be about 10mm, the thickness deviation of the 10mm board according to the national standard of the JCT564-2018 fiber reinforced calcium silicate board industry is +/-0.4 mm, the thickness standard requirement can be completely and easily realized, the produced primary blank is conveyed to the thickness setting device 3 through a fast conveying belt 22 and a slow conveying belt 23, and the primary blank is rolled by a thickness setting device 3 through upper and lower pairs of rollers. When the initial blank enters the blank body of the slow conveying belt 23 of the fixed thickness device 3, the running speed of the slow conveying belt 23 is firstly reduced to be below 1/3 of the speed of the fast conveying belt 22, so that the fixed thickness device 3 can roll at a low speed; the running linear speed of the roll shaft of each group of paired rolls of the fixed thickness device 3 is 1.1-1.3 times of the speed of the slow conveying belt 23, and the specific speed is linked with the speeds of the fast conveying belt 22 and the slow conveying belt 23; the standard thickness of each pair of upper and lower squeeze rolls can be set or the thickness can be accurately detected by up-down correlation of a laser displacement sensor and then fed back to the vertical adjusting component 323 to automatically control the gap between the upper and lower squeeze roll shafts, the gap between the left and right pair of rolls of the thickness determining device 3 is reduced in a descending manner (two or three pairs of rolls are generally arranged), and finally the thickness of the primary blank is controlled within the standard thickness value and the deviation range of the process requirement. Generally, the thickness of the slab processed by the thickness setting device can be realized within ± 0.2 mm.
