Abstract
The invention provides a production process for a PP waste packing belt. The process comprises the steps that waste PP is collected, cleaned and dried, and then the waste PP and powdery filler are mixed and fed; a main extruder is used for carrying out plasticizing mixing and waste filtration; an auxiliary extruder is used for evenly and continuously supplying clean PP melt; and the PP melt is placed into a cooling tank to be cooled, dried and drawn in a drying box, subjected to knurling and thermal shaping and then subjected to cooling shrinkage in an ice water tank, and finally the PP melt is coiled to form a finished product. According to the production process, the waste PP is collected and reutilized, so that resources are saved, and plastic pollution to the environment is reduced. In the cooling and sizing process, as the number of transmission teeth of a first steel wheel is less than that of transmission teeth of the other three steel wheels, and the four steel wheels are all driven by a motor, the rotating speed of the first steel wheel is lower than that of the other steel wheels, so that the time of shrinkage of the PP packing belt passing through the ice water tank is prolonged. Thus, the PP packing belt is not likely to have large deformation after being coiled into the finished product, and the overall quality is improved.
Description
Technical field
The present invention relates to the production technology of a kind of strap, be specially the production technology of a kind of PP waste material strap.
Background technology
PP strap, formal name used at school polypropylene, it it is one lighter in common plastics, the main material of PP strap is polypropylene wiredrawing grade resins, PP strap has lovely luster, attractive in appearance, light weight, specific strength is big, flexible, non-corrosive, it is not afraid of humidity, it is not afraid of corrosion, acid and alkali-resistance, water absorption, hygroscopicity is only small, plasticity is good, tensile fracture is strong, resist bending, light specific gravity, the advantage such as easy to use, intensity is not reduced after immersion, use the advantages such as operation safety, it is widely used to household items, weaving, clothing, telecommunication instrument, bookstore, the aspects such as the packaging of post and telecommunications and exported product, plastic baling band per ton can substitute for 4～5 tons of steel bands, show very big superiority.
The plastic baling band of current domestic use has the materials such as polypropylene, polyethylene and polrvinyl chloride, wherein based on polypropylene plastics strap, accounts for the 90% of plastic baling band yield.The production process of polypropylene and vinyon strap is essentially identical.PP strap is that PP GRANULES material is put into extruder, and material is melted by hot melt, is extruded into band through head, then through stretch and the operation such as embossing polypropylene plastics strap.
PP waste plastics all can produce a lot, the PP waste plastics recovery that cannot recycle to be become product PP strap, not only saves resource but also reduce plastic pollution environment every year.
In PP strap produces, often have when PP strap is rolled into finished product and produce very big deformation, the total quality of plant produced PP strap can be reduced, also can waste very big human resources in this respect.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that the production technology of a kind of PP waste material strap.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
The present invention provides the production technology of a kind of PP waste material strap, PP waste material is carried out, dries, PP waste material and fleur mixing blanking afterwards, first pass through main extruder plasticizing mixing and filtering spam, uniformly constantly provide clean PP melt then through secondary extruder, under PP melt, cooling bath cools down, be then passed through baking box and carry out baking stretching, afterwards through embossing, hot shaping and frozen water tank cooling and shaping, finally it is wound into finished product.
As a preferred technical solution of the present invention, when PP waste material is with fleur mixing blanking, PP waste material is initially positioned at inside the silo of main extruder, and fleur is initially positioned at inside the pulverulent fillers bucket above main extruder, PP waste material and fleur Homogeneous phase mixing is made by buncher and agitating device
As a preferred technical solution of the present invention, when through main extruder plasticizing mixing, by the filter screen in main extruder, and filter wherein low-density polyethylene, impurity particle and be not plasticized the material of mixing.
As a preferred technical solution of the present invention, clean PP melt from main extruder out after, through the storage bin hopper of secondary extruder and store.
As a preferred technical solution of the present invention, when cooling and shaping, adopting four and just take turns with diameter, the transmission number of teeth that the transmission number of teeth of first steel wheel compares other three steel wheels is few, PP strap, after baking box to first steel wheel, tentatively contracts back to the other three steel wheel then through frozen water tank.
The present invention reaches to provide the benefit that:
1, PP waste plastics is collected recycle, not only save resource but also reduce plastic pollution environment；
2, after PP waste material is carried out, dries, by solving plastic molting and the impurity filtered in melt with main extruder, improve the quality of product, when the filter screen in main extruder needs to change, enough melts are stored by the storage bin hopper of secondary extruder, the raw material produced required for strap is uninterruptedly provided, improves production efficiency；
3, in cooling and shaping, owing to the transmission number of teeth of other three steel wheels of transmission gear ratio of first steel wheel is few, and by same driven by motor, therefore, first steel wheel is very fast relative to the rotating speed of other steel wheel, which adds PP strap through the space producing to shrink through frozen water tank, thus no longer having very big deformation after PP strap is rolled into finished product, directly should require needed for having fully met full-automatic unmannedization, improves total quality.
Accompanying drawing explanation
Accompanying drawing is for providing a further understanding of the present invention, and constitutes a part for description, is used for together with embodiments of the present invention explaining the present invention, is not intended that limitation of the present invention.
In the accompanying drawings:
Fig. 1 is production technological process of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention.
Embodiment: as shown in Figure 1, the present invention provides the production technology of a kind of PP waste material strap, PP waste material is carried out, dries, PP waste material and fleur mixing blanking afterwards, first passes through main extruder plasticizing mixing and filtering spam, uniformly constantly provides clean PP melt then through secondary extruder, under PP melt, cooling bath cools down, it is then passed through baking box and carries out baking stretching, afterwards through embossing, hot shaping and frozen water tank cooling and shaping, be finally wound into finished product.
When PP waste material is with fleur mixing blanking, PP waste material is initially positioned at inside the silo of main extruder, and fleur is initially positioned at inside the pulverulent fillers bucket above main extruder, made PP waste material and fleur Homogeneous phase mixing by buncher and agitating device
When through main extruder plasticizing mixing, by the filter screen in main extruder, and filter wherein low-density polyethylene, impurity particle and be not plasticized the material of mixing.
