Detailed description of the invention
The present invention is further described below in conjunction with the drawings and specific embodiments.
See Fig. 1 to Fig. 2, the throwing roller arrangement 100 of the spreading machine provided in figure, comprises two pieces of frame plates 101 forming and throw roller arrangement 100 two side that be arranged in parallel; Frame plate 101 selects 3158 × 3130 × 20 millimeters of steel plate processing.
Between two pieces of frame plates 101, be provided with the discharging chamber 110 becoming certain inclination angle with level, the below in discharging chamber 110 is provided with the discharging opening 111 sending fiber, and discharging chamber 110 is provided with material mouth 113 towards the side 112 of feed bin; And in discharging chamber 110 dorsad the bottom of the side 114 of feed bin be provided with maintenance magnetic separation door 115.
10 the material casting rollers 104 becoming certain inclination angle with level are provided with in the position of the material mouth 113 in discharging chamber 110.Each throwing roller 104 is assembling parts, is made up of the axle sleeve on axle and installation shaft and blade, and blade and axle sleeve interlock and assemble, and two ends M68 × 2 nut checks, axle is made up of 45 rod irons of ∮ 80 × 1822, and blade is processed by cold rolling carbon steel Q235A.Axle sleeve is made up of carbon steel Q235A.
Each material casting roller 104 is thrown roller motor 106 by one and is driven, throwing roller motor 106 for 10 is arranged on two pieces of frame plates 101 respectively, every block frame plate 101 is provided with 5 and throws roller motor 106, throwing roller motor 106 is reducing motor, selects the FA47/GDRE100M4/TF/M5/A high efficiency motor that SEW company produces.
See Fig. 3, throw roller motor 106 and adopt electric machine support 105 to be arranged on frame plate 101, electric machine support 105 60 × 40 × 4 rectangular tubes and Plate Welding are processed.
The two ends of material casting roller 104 all adopt bearing block 104a to be arranged on frame plate 101, and bearing block 104a selects SKF rolling bearing units FY50TF.
One end of material casting roller 104 is connected by shaft coupling with the output shaft of reducing motor.
10 each freedom of material casting roller 104 are independently thrown roller motor 106 and are driven, and force to be thrown into sending the fiber of feeding mouth 113 in discharging chamber 110.Equidistantly arrange between 10 material casting rollers 104.10 material casting roller 104 arranged in groups and the certain inclination angle of level, each material casting roller 104 is assembled by the disc-like wafer of numerous star is staggered.Fiber in feed bin can obtain preferably fiber separation through the pressure material casting of material casting roller 104, is laterally forming uniform stream.
Discharging chamber 10 is separated into the equal independently sub-discharging chamber 116 of 8 width along the axis direction being parallel to material casting roller 104 by 7 pieces of flow distribution plates 102, after fiber is dished out by material casting roller 104 pressure, freely fall along each independently sub-discharging chamber 116, non-interference between the fiber in each independently sub-discharging chamber 116, make blanking more even.7 pieces of flow distribution plates 102 select 1950 × 2060 × 3 millimeters of cold rolling carbon steel Q235A to process, and they are fixed on frame plate 101 by the six roots of sensation little axle 102a, 102b and nut.
Offer air port 107a on the top of each independently sub-discharging chamber 116 side 114 of feed bin dorsad, air port 107a is stamped air door 107, and 8 air door 107 steel plate flangings are made.
See Fig. 4 and Fig. 5, be provided with a long kidney-shaped hole (not shown) on the top of each air door 107, the upper limb in air port is provided with a bolt A, bolt A is also tight with nut B through long kidney-shaped hole.When needs increase air amount, first unscrew locking nut A, bolt B is unclamped, damper 107 upwards.When needs reduce air capacity, unscrew locking nut A, bolt B is unclamped, damper 107 is downward.Adjustment terminates, then is locked by nut A.The size that damper 107 is opened, effectively controls fiber falling speed, thus make fiber thickness and density more even.
When producing the slab of different-thickness, upper and lower by damper 107, the size that damper is opened, air capacity is applicable to, and adjustment turns clockwise and the material casting roller different rotating speeds be rotated counterclockwise, effective control fiber falling speed, makes fiber even, thus improves production board qualification rate.
Between 7 pieces of flow distribution plates 102, be inserted with one piece of dividing plate 103, division board 103 is positioned at flow distribution plate 102 central authorities, entering air in air port, making air curve enter discharging bin 110 for isolating straight line.Monoblock division board 103 is processed by 1450 × 1290 × 10 millimeter of 3240 phenolic laminated sheet.Whole phenolic laminated sheet offers 7 slots, inserts for 7 pieces of flow distribution plates 103.
The lower end of this dividing plate 103 and the side 114 from discharging back lining to feed bin between leave air intake passage 103a.
Above-mentioned a kind of using method with air door adjustment in the throwing roller arrangement of the spreading machine of adjustable damper is: first according to the thickness of slab, if production slab, when needs increase air amount, first unscrew locking nut A, bolt B is unclamped, and damper 107 upwards.If production thin plate, when needs reduce air capacity, unscrew locking nut A, bolt B is unclamped, damper 107 is downward.Adjustment terminates, then is locked by nut A.
The throwing roller arrangement of the spreading machine of the present embodiment is applied on 4 feet of (1220 millimeters) fiberboard complete production lines, successfully solve slab fiber pavement thickness, a Density inhomogeneity difficult problem, the pattern for thin plate fibreboard production line provides foundation and reference.
Due to medium density fiber production line, because it is different to produce slab thickness, plate blank paving thickness is also different.Especially for sheet billet of mating formation, damper size, control fiber and mat formation evenly extremely important, the production board produced like this is best in quality.
A kind of throwing roller arrangement with the spreading machine of adjustable damper of the present invention just can be applied on the Midst density complete production line of the various breadth such as 4 feet (1220 millimeters), 8 feet (2440 millimeters) by arranging air door quantity, and other similar production equipment.
