Description
Technical field
The utility model belongs to BOPP production technical field, is specifically related to a kind of BOPP co-extrusion device for suction material, the co-extrusion powder of the appearance can effectively eliminate BOPP production time.
Background technology
The problem that all can run into powder as long as relating to the producer of stir mixing, I take charge of the BOPP production line of having introduced a German Bruckner in 1998, also run into similar problem in the process of vacuum co-extrusion suction.According to the configuration of original equipment, its adopts powder has directly been blown into the working method of extrusion device, and in actual production, powder can cause that some exhausts are smooth, the even negative effect of rupture of membranes of pressure oscillation.The appearance of this impact is random and unpredictable, together with being sometimes entrained in other rupture of membranes reason, has increased the difficulty of technique judgement.
Powder comes from the process that batch mixing stirs, and has certain relation with shape and the formula Design of material.Generally speaking, broken less in the process that surperficial smoother and circular pellet stir at batch mixing, therefore powder is also less, otherwise than being easier to produce powder.Concerning manufacturer, the shape that changes material relates to the raw material supply of upstream, and improves material surface smoothness and many times conflict mutually with the formula Design of product, and the difficulty that solves this problem by raw material is very large, and operability is not strong.In actual production, expect to seek by the method for scrap build the method for a powder difficult problem that solves co-extrusion suction.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of BOPP co-extrusion device for suction material is provided, and the co-extrusion powder of the appearance while utilizing this device can effectively eliminate BOPP production, avoids pressure oscillation and rupture of membranes, improves the stability of producing.
In order to realize foregoing invention object, the technical solution adopted in the utility model is:
A kind of BOPP co-extrusion device for suction material, comprises hopper, suction bucket, raw material hopper, filter bag, air inlet pipe and vavuum pump; Vavuum pump is connected with suction bucket by air inlet pipe; Suction bucket bottom is connected with hopper, and middle part is connected with raw material hopper by feed pipe, and top arranges filter bag; After vavuum pump is evacuated suction bucket, raw material in raw material hopper is sucked to suction bucket, then blow raw material is blown in hopper, it is characterized in that, between vavuum pump and air inlet pipe, air filter is set.
Further, described air filter comprises air cleaner, spring and shell, and described air cleaner arranges spring between air cleaner and top cover within being arranged on the dismountable shell of top cover.
Further, described filter bag is made up of low-density fibre cloth, the density of its fiber be controlled at just can make powder by and pellet can not pass through.
The utility model, by increase air filtration unit in existing co-extrusion device for suction material, is tackled the powder in suction process get off by this device, the more auxiliary problem that just can solve powder that regularly manually cleans; In addition, make the high-density fiber cloth in existing equipment into low-density fibre cloth, ensure that powder is sucked into vacuum plant, pellet but can not pass through filter bag.
The beneficial effects of the utility model are: the co-extrusion device for suction material that practical the utility model provides, in BOPP production process, raw-material powder no longer enters extrusion system, the production problems such as blanking bridge formation, pressure oscillation and the rupture of membranes often occurring before can avoiding, have improved production stability.The utility model is simple in structure, installs some parts additional and carry out suitable transformation and can eliminate the powder harm difficult problem in extrusion on existing equipment basis, economical and practical with low cost.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Existing BOPP co-extrusion device for suction material structure as shown in Figure 1, is mainly made up of hopper 1, suction bucket 3, raw material hopper 9, filter bag 4, inflatable mouth 12, magnetic valve 12, air inlet pipe 7 and vavuum pump 10 etc.; Vavuum pump 10 is connected with suction bucket 3 by air inlet pipe 7; Suction bucket 3 bottoms connect hopper 1, and middle part is connected with raw material hopper 9 by feed pipe 8, and top arranges filter bag 4.Its basic functional principle is as follows: when unlatching vavuum pump 10 is worked, magnetic valve 12 drives cylinder 6 to open the rubber gasket 5 of bleeding point, by air inlet pipe 7, negative pressure state is pumped into in the inside of suction bucket 3, be played sealing function in moment sealing plate 2 meetings that start by negative pressure adhesive, the granular material of extracting out in raw material hopper 9 arrives suction bucket 3; Program above completes final vacuum pump 10 and stops, inflatable mouth 11 starts to blow under the control of magnetic valve 12, suction bucket inside becomes normal pressure, granular material backs down sealing plate 2 and enters hopper 1 under the effect of deadweight, and inflatable mouth 11 has also blown into the powder in material in hopper 1 in the process of blowing.
The utility model structure as shown in Figure 2, on original structure basis, arranges air filter between vavuum pump 10 and air inlet pipe 7.Air filter comprises air cleaner 14, spring 15 and air filter housing 13, and air cleaner 14 arranges holddown spring 15 within being arranged on the dismountable air filter housing 13 of top cover between air cleaner 14 and top cover.In addition, filter bag 4 also makes low-density fibre cloth into from high-density fiber cloth to be made, and the density of its fiber is controlled at and just can makes powder enter vacuum plant by filter bag, and pellet is stayed to hopper.
The BOPP co-extrusion device for suction material that adopts the utility model to provide, the powder in raw material is by low-density fibre cloth, through air inlet pipe 7, under being tackled by air filter before vavuum pump 10, collect after certain amount, open the top cover of air filter, by manually cleaning.Select the cleaner of suitable size according to the actual conditions of producing, take into full account amount of powder and manual clean frequency, may take too greatly more space, too little there will be frequently, is manually cleaned.After having installed this device additional, the production problems such as the blanking bridge formation, pressure oscillation and the rupture of membranes that cause because of powder problem in production significantly reduce.
Above-described embodiment object is to make professional and technical personnel in the field to understand the technical solution of the utility model and to be implemented according to it; can not limit with it protection domain of this patent; all distortion of doing according to the utility model disclosure technology, all fall into protection domain of the present utility model.
