Abstract
The invention discloses a method for producing a plastic strip. The method includes the following steps: plastic particles are put into a hopper of an extruder; the extruder extrudes the plastic particles which are heated to a temperature of 160-170 DEG C in a spiral manner to obtain the plastic strip; after being cooled by cooling water, the plastic strip is pressed and formed by a roller; after being pressed and formed, the plastic strip is cut off by a cut-off tool to obtain the plastic strip with a required length; finally, the plastic strip is checked out and then put in storage. According to the invention, the production is convenient, the production cost is low, and the plastic strip is liable to the environment-friendly treatment or recycling.
Description
Technical field
The present invention relates to a kind of plastic products, particularly a kind of production method of plastic strip.
Background technology
At present seal at mouth mask, food bag the plastic strip used is inner employing wire outsourcing plastics, and it exists following defect, 1, wire gets rusty easily variable color, affects outward appearance; 2, heavier-weight, and production cost is improved; 3, wire easily scratches mouth mask and food bag sealing, may affect the safety of user; 4, production technology is comparatively complicated, must by plastic wraps in appearance wiry; 5, make troubles due to wire when processing or reclaim mouth mask, food bag.And existing pure plastic strip is all have certain elasticity, this inside cannot be substituted there is plastic strip wiry.
Summary of the invention
The object of the invention is to, a kind of production method of plastic strip is provided.The present invention is convenient for production, production cost is low and easy environmental protection treatment or recovery.
Technical scheme of the present invention: a kind of production method of plastic strip, it is characterized in that: hopper plastic grain being put into extruder, extruder will be heated to the mode extrusion plastic bar of plastic grain by spiral squeezing of 160-170 DEG C of temperature, plastic strip is after water quench, again by roller die mould, plastic strip after die mould carries out Len req cut-out through cutoff tool, and be finally up to the standards warehouse-in.
In the production method of aforesaid plastic strip, the extrusion method of described extruder is, reducing motor drives reduction box through belt transmission, in the effect through shaft coupling, drive twin-screw rotates, and plastic grain is added in material extrusion case, is undertaken carrying, extruding by the twin-screw rotated, from extruded tube discharging, mounting heater heating of plastic particle in extruded tube.
In the production method of aforesaid plastic strip, the method that described cutoff tool carries out Len req cut-out is, respond to Len req by infrared sensor, and control dip mold and press down, thus make the cutoff tool be arranged on dip mold carry out the cut-out of Len req to plastic strip.
In the production method of aforesaid plastic strip, described plastic strip is made up of the component of following weight portion: polyethylene 60-65 part, calcium carbonate 20-25 part, polyethylene color masterbatch 15-20 part.
In the production method of aforesaid plastic strip, described plastic strip is made up of the component of following weight portion: polyethylene 62 parts, 22 parts, calcium carbonate, polyethylene color masterbatch 16 parts.
Compared with prior art, the present invention is owing to shaping, alternative inside adopts the existing plastic strip of wire outsourcing plastics, abolish in existing plastic strip and wire necessarily need be adopted to be fixed the custom of sizing, and wire can be avoided to get rusty, surface plastic materials variable color, the even situation of wire prick into human body, and decrease production process, make whole production technology comparatively simple, alleviate the weight of product, reduce production cost, also make the appearance of relative product more attractive in appearance, give in process simultaneously or reclaim mouth mask, bring conveniently during food bag, a kind of ideal plastic strip substitute products meeting environmental protection.The present invention is convenient for production, production cost is low and easy environmental protection treatment or recovery.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further illustrated, but not as the foundation limited the present invention.
Embodiment.A kind of production method of plastic strip, it is characterized in that: hopper plastic grain being put into extruder, extruder will be heated to the mode extrusion plastic bar of plastic grain by spiral squeezing of 160-170 DEG C of temperature, plastic strip is after water quench, again by roller die mould, plastic strip after die mould carries out Len req cut-out through cutoff tool, and be finally up to the standards warehouse-in.
The extrusion method of described extruder is, reducing motor drives reduction box through belt transmission, in the effect through shaft coupling, drive twin-screw rotates, plastic grain is added in material extrusion case, undertaken carrying, extruding by the twin-screw rotated, from extruded tube discharging, mounting heater heating of plastic particle in extruded tube.
The method that described cutoff tool carries out Len req cut-out responds to Len req by infrared sensor, and control dip mold and press down, thus make the cutoff tool be arranged on dip mold carry out the cut-out of Len req to plastic strip.
Described plastic strip is made up of the component of following weight portion: polyethylene 60-65 part, calcium carbonate 20-25 part, polyethylene color masterbatch 15-20 part.
Described plastic strip is made up of the component of following weight portion: polyethylene 62 parts, 22 parts, calcium carbonate, polyethylene color masterbatch 16 parts.
