Abstract
The invention discloses a kind of production methods of woven bag, are as follows：Step 1: plastic raw materials are heated, are filtered, squeeze out film in blocks；Step 2: piece film through supercooling, dry coating material layers after cut into and cut open silk；Step 3: cut open silk is made flat filament after heating, stretching cooling；Step 4: flat filament using braider be woven into the braiding cylinder of continuous tubular；Step 5: the braiding cylinder after braiding is scalded to the braiding semi-finished product bag for being cut into two open ends by predetermined size with heater strip；Step 6: the semi-finished product bag of braiding is formed after sewing one end close, the finished product woven bag of one end open.Woven bag both ends produced by the invention are scalded using heater strip cuts, sack end not filoselle, the closely knit no loophole material leakage phenomenon of structure, and manufactured size is consistent, stable quality.
Description
Technical field
The present invention relates to woven bag processing technique field more particularly to a kind of production methods of woven bag.
Background technology
Polywoven Bag is now widely used in a kind of packaging material of fertilizer, chemical industry, crops and other items；It is mainly produced
Technique is into flat filament shape, by woven bag is made through knitting device using the extruded film of plastic raw materials, cutting and simple tension.
Traditional mode of production mode be easy to cause woven bag filoselle, not closely knit enough the material leakage phenomenon that starts a leak, and manufactured size is not
One, quality is not sufficiently stable.
Invention content
Present invention aim to address above-mentioned deficiencies, provide a kind of production method of woven bag.
A kind of production method of woven bag of the present invention, is as follows：
Step 1: plastic raw materials are heated, are filtered, squeeze out film in blocks.
Step 2: piece film through supercooling, dry coating material layers after cut into and cut open silk.
Step 3: cut open silk is made flat filament after heating, stretching cooling.
Step 4: flat filament using braider be woven into the braiding cylinder of continuous tubular.
Step 5: the braiding cylinder after braiding is scalded to the braiding semi-finished product for being cut into two open ends by predetermined size with heater strip
Bag.
Step 6: the semi-finished product bag of braiding is formed after sewing one end close, the finished product woven bag of one end open.
Woven bag both ends produced by the invention are scalded using heater strip cuts, and filoselle, the closely knit no loophole of structure do not leak for sack end
Expect phenomenon, and manufactured size is consistent, stable quality.
Specific embodiment
Below by embodiment to further instruction of the present invention, the embodiment of the present invention is with technical scheme of the present invention
Premised under implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is unlimited
In following embodiments：
A kind of production method of woven bag, is as follows：
Step 1: plastic raw materials are heated, are filtered, squeeze out film in blocks.
Step 2: piece film through supercooling, dry coating material layers after cut into and cut open silk.
Step 3: cut open silk is made flat filament after heating, stretching cooling.
Step 4: flat filament using braider be woven into the braiding cylinder of continuous tubular.
Step 5: the braiding cylinder after braiding is scalded to the braiding semi-finished product for being cut into two open ends by predetermined size with heater strip
Bag.
Step 6: the semi-finished product bag of braiding is formed after sewing one end close, the finished product woven bag of one end open.
