Description
Technical field
The utility model relates to a kind of three-roller automatical feeding system produced for offset ink, belongs to offset ink production equipment technical field.
Background technology
Relatively more conventional when three-roller is offset ink production is also important milling apparatus.Common three-roller material loading is generally artificial loading, because relating to output not quite general is one batch with about 500 kilograms, artificial loading is fast more convenient.But the Printing ink producing amount of large-scale ink enterprise every batch is in ton, the build of corresponding three-roller is also huger, and hand stock, just be not as so convenient as small-sized three-roller, must use some mechanical assistance instruments ability material loading smoothly, loading efficiency is low, and fastness intensity is large; Simultaneously because three-roller is opening equipment, easily cause foreign material to enter three-roller during hand stock, affect ink quality, meeting damage equipment time serious, also there is certain potential safety hazard during hand stock, therefore need to develop a kind of three-roller automatical feeding system produced for offset ink
Chinese utility model patent, the patent No.: 201320823786.8, disclose one " the three-roller automatical feeding system for offset ink is produced ", this patent realizes the three-roller automatic charging that offset ink is produced, and the artificial loading overcoming prior art on the one hand easily introduces impurity, affects the deficiency of offset ink quality, on the other hand, save manpower, reduce the labour intensity of operator, substantially increase production efficiency and production security.
But in practical operation find when feed pipe by feed pump by ink inspiration three-roller time, due to the characteristic of the thickness of ink own, when feed pipe sucks ink, even supply (ink sucking that block can not get the supply of ink around) is can not get after ink in material cylinder sucks, the ink entering three-roller cuts in and out, and affects the charging control of three-roller.
Utility model content
For the problems referred to above that existing three-roller is reinforced, the structure on the utility model design optimization three-roller charging (feeding) equipment, to feed in raw material uneven problem to solve existing charging (feeding) equipment.
The technical solution of the utility model is: the utility model comprises three-roller, and be fixed at the feeding chamber at three-roller top, described equipment also comprises PLC, material conveying mechanism, the electrical-controlled lifting mechanism be elevated for driving material conveying mechanism and material cylinder drive unit, described material conveying mechanism is by feed pipe, feed pump and discharge nozzle are formed by fixedly connecting, feed pipe is fixed with the first liquid level sensor near entrance point, the outlet of discharge nozzle is positioned at the top of feeding chamber, the inwall of feeding chamber is fixed with the second liquid level sensor, described material cylinder drive unit comprises circular material cylinder, rotatable platform and servomotor, rotatable platform comprises fixed head and is arranged on the rotor plate in the middle of fixed head, described circle material cylinder is placed on rotor plate, fixed head is provided with two backstays for positioning round material cylinder, backstay is provided with two rollers near circular material cylinder side, rotor plate lower end is connected with servomotor by driving-belt, electrical-controlled lifting mechanism, feed pump, first liquid level sensor, second liquid level sensor is all connected with PLC with servomotor.
With circular, described charge pipe expects that the lateral separation of casing wall is 10cm-15cm.
The beneficial effects of the utility model are: three-roller automatic charging equipment of the present utility model, the artificial loading overcoming prior art on the one hand easily introduces impurity, affect the deficiency of offset ink quality, save manpower, reduce the labour intensity of operator, substantially increase production efficiency and production security; On the other hand, by devising a servomotor in material cylinder bottom portion, driving material cylinder to carry out back rotation by servomotor, solving the problem that discharging is uneven in reinforced process.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: the utility model of the present utility model comprises three-roller 1, and be fixed at the feeding chamber 1-1 at three-roller 1 top, described equipment also comprises PLC 5, material conveying mechanism, the electrical-controlled lifting mechanism 6 be elevated for driving material conveying mechanism and material cylinder drive unit, described material conveying mechanism is by feed pipe 7, feed pump 4 and discharge nozzle 3 are formed by fixedly connecting, feed pipe 7 is fixed with the first liquid level sensor 8 near entrance point, the outlet of discharge nozzle 3 is positioned at the top of feeding chamber 1-1, the inwall of feeding chamber 1-1 is fixed with the second liquid level sensor 2, material cylinder drive unit 10 comprises circular material cylinder 9, rotatable platform 10 and servomotor 12, the rotor plate 14 that rotatable platform 10 comprises fixed head 13 and is arranged in the middle of fixed head 13, circular material cylinder 9 is placed on rotor plate 14, fixed head 13 is provided with two backstays 15 for positioning round material cylinder 9, backstay 15 is provided with two rollers 16 near circular material cylinder 9 side, rotor plate 14 lower end is connected with servomotor 12 by driving-belt 11, electrical-controlled lifting mechanism, feed pump 4, first liquid level sensor 8, second liquid level sensor 2 is all connected with PLC 5 with servomotor 12.
And control charge pipe 7 with circular and expect that the lateral separation of cylinder 9 wall is 10cm-15cm, can ensure that charge pipe is near expecting casing wall position, when circle material cylinder rotates, better can be drawn onto ink.
Operation principle of the present utility model is: first move to below feed pipe 7 by the circle material cylinder 9 being contained with ink material, ensure with circular, charge pipe 7 expects that the lateral separation of cylinder 9 wall is in the position of 10cm-15cm, starting electrical-controlled lifting mechanism 6 drives material conveying mechanism slowly to decline, when the first liquid level sensor 8 of feed pipe 7 lower end has detected liquid level, PLC 6 has controlled to start feed pump 4 and has driven ink material to enter into the feeding chamber 1-1 of three-roller 1 through feed pipe 7 and discharge nozzle 3; In material conveying process when material liquid level in material cylinder drop to the first liquid level sensor 8 liquid level cannot be detected time, PLC 5 can control electrical-controlled lifting mechanism 6 and decline, and then drives material conveying mechanism to decline until electrical-controlled lifting mechanism just stops decline when the first liquid level sensor 8 detects liquid level; On the other hand, material accumulates in the feeding chamber 1-1 of three-roller 1, and in feeding chamber 1-1, liquid level also can rise, and when the liquid level higher limit of arrival second liquid level sensor 2 setting, PLC 5 can control feed pump and close stopping conveying; Along with the material in feeding chamber progressively enters three-roller 1, when the liquid level in feeding chamber arrives the bottom level limit of the second liquid level sensor 2 setting, PLC 5 can control feed pump unlatching and carry out conveying work.
While PLC 5 starts feed pump 4 conveying, PLC 5 starts servomotor 12, and servomotor 12 drives rotor plate 14 to carry out back rotation by driving-belt 11, and feed pipe 7 suction always can be kept even, and at fixed head 13
On backstay 15 can prevent circular material cylinder when rotating because centrifugal force is shifted, ensure the normal operation of conveying.
