Description

The liquid phase noumenal method polypropylene automatic feeding packing device of weighing

The utility model belongs to class of jobs and relates to a kind of device, especially packing device of liquid phase noumenal method polypropylene product of carrying and packing solid material.

In known technology, the packing of product of existing liquid phase noumenal method polypropylene process units mainly is the manual operation packing, adopts the discharge control cock bottom bottom polypropylene flash distillation still that platform scale, other flanging machine, capper, the chopping machine placed of scale are set.Finish in the flash distillation of flash distillation still, after check propylene gas content is qualified, opening at the bottom of the still control cock by the operative employee stares at platform scale by operative employee's hand support packaging bag eye in addition again and connects material to weigh to shift out after waiting to be filled to quantitatively and change bag, and so forth, discharge pack weighing and bagging, its operative employee's labour intensity height, work capacity is big, artificial weighting error is also big, especially the friction of polypropylene Flow of Goods and Materials very easily produces static, adds that a small amount of propylene residual gas mixes with atmosphere, easily takes place to dodge quick-fried, there is hidden danger, the polypropylene product that is packing again is the granular material dust from flying, is directly endangering operator's health and safety, and need to close baiting valve again after single still product has been arranged, opening vacuum pump vacuumizes, charge into nitrogen then in still, its technology is complicated, power consumption is high, and also production brings inconvenience to device.Know that again existing automatic rating packing controller is that the electromechanics that is grouped into of mechanics and electrical control division by scale is in conjunction with product, DCS-25 (50) A-I as the development and production of Changzhou knob prestige automatic packaging machine works, II, III type automatic rating packing controller, formed by scale main body and electrical control cabinet exactly, be equiped with the FX2N-80MR Programmable Logic Controller in the electrical control cabinet and connect the scale main body respectively by circuit, the conveyer at the material control valve of scale body front portion and scale body rear portion, flanging machine, sack closer and chopping machine, handle the electrical control button, under the PLC instruction, just can finish the blowing of setting automatically, weighing, carry, packaging process.It is suitable for cooperating the liquid phase noumenal method polypropylene packing of product device of development of new.

The purpose of the utility model provides a kind of improved liquid phase body polypropylene product feeding packing device, it can realize automatic feeding, weigh and pack by operation electrical control button, reduce operator's labour intensity and work capacity greatly, improve operating environment, and the work efficiency height, power consumption is low, weighing is accurate, the device safe in operation, easy and simple to handle.

For achieving the above object, the technical solution adopted in the utility model is: the single stills of several polypropylene flash distillations are established threeway at folder between the automatic controlling valve of each still bottom drain hole and the manually actuated control valve be connected feeding pipe, be connected in storage tank by the pipeline collection, the conjuncted material gas separating device that is shaped in storage tank top, install automatic controlling valve on the jar end drain hole, control cock bottom load auxiliaring bucket, feed hopper bottom connects the explosion proof type automatic rating packing controller, scale bottom installing conveyer, flanging closer and chopping machine, the electrical control cabinet of automatic rating packing controller by circuit respectively with the scale main body, the control feeding valve, conveyer, the flanging closer is connected with chopping machine, organize to be linked to be and be the polypropylene product automatic feeding packing device of weighing.During use, after propylene gas permutation test in the flash distillation still flash distillation end still is qualified, open the nitrogen pipeline master cock and in still, fill nitrogen to setting pressure, press and open blowing automatic controlling valve at the bottom of the still, the polypropylene product material under the nitrogen effect by still at the bottom of three feeding pipes that stimulate the menstrual flow send into storage tank, treat that the product force feed finishes in the still after, close baiting valve at the bottom of the still, owing to be the nitrogen state in the still, can directly carry out flash distillation again, so cycle operation by polymeric kettle material spray in the flash distillation still.Defeated deposit in the storage tank the polypropylene product material by the operative employee press open jar at the bottom of the control cock button, the product material is by the packaging bag of valve bottom on hopper inflow automatic rating packing controller, after carrying out the quantitative weighing pack, by conveyer defeated through flanging closer flanging seal, after chopping machine prints, the check warehouse-in.

Because the new-type feeding packing device that the utility model design has adopted the strength feeding to concentrate the storage tank Automatic weighing and packaging to carry, compared with the prior art, its advantage is that operator's pressing device action button just can carry out the automatic discharging of product, conveying, collection storage, automatic weighing and package handling.Through testing on probation showing for several times, the inferior only nitrogen of the every still of flash distillation still of device trail run can be saved more than 60%, the packing weighing precision improves more than 10 times, and operator's labour intensity and work capacity have been alleviated greatly, also reduced dust pollution greatly, especially package unit adopts nitrogen to carry and the electrostatic prevention facility, eliminated effectively by static and caused the hidden danger that sudden strain of a muscle is quick-fried, its novel structure, reasonable in design, level advanced person, safe in operation, easy and simple to handle, popularizing application prospect is wide, be applicable to many stills intermittent cyclic formula, the feeding and the packing of new type of continuous production formula liquid phase noumenal method polypropylene product are a kind of later-model material package device.
