Description
Technical field
The present invention relates to technical field of textile equipment more particularly to a kind of dust-extraction units for Weaving device.
Background technique
Weaving device is a kind of mechanical equipment for natural fiber or chemical fibre being processed into textile.Weaving device into
A large amount of battings and dust can be generated when row weaving operation, such as essential Weaving device-in lint after-finishing of textile products process
Natural lustre finishing machine can generate a large amount of oil-containing battings in use.The a large amount of battings and dust generated when weaving operation not only will affect
The normal operation of Weaving device can also cause very big harm to spinning and weaving workshop environment, and the person for seriously endangering operator is strong
Health, thus need to be arranged dust-extraction unit, the batting of generation and dust are cleaned out by Weaving device by dust-extraction unit, and to cleaning
The batting of Weaving device and dust are filtered and collect out.
Dust-extraction unit common at present uses tubular filter screen structure, generates position in batting, the dust of Weaving device and sets
Air inlet is set, tubular filter screen one end is connected with air inlet, and air inlet is set to by vacuum means, and vacuum suction is provided, thus
The batting generated in Weaving device, dust are sucked into tubular filter screen and are filtered.The wind direction generated due to vacuum suction
It is certain, thus tubular filter screen only has the strainer of about half area in effectively filtering batting and dust, only when this half
Strainer blocked by batting and dust after, the other half strainer just plays filtering function, thus the mistake of tubular filter screen at any time
Filtering surface product is not all using complete.Furthermore for a long time using the mesh of rear strainer can gradually be attached to batting on tubular filter screen and
Dust is blocked, thus needs periodic cleaning tubular filter screen.
At present by using the batting and dust adhered on two kinds of collection mode cleaning tubular filter screens：
First way is to use to artificially collect mode：It is artificial to pat tubular filter screen, make the batting being attached on strainer and powder
Dirt is fallen in collecting bin, but artificially collecting mode in operation needs to close vacuum evacuation device, and operating process is also compared
Trouble, it is time-consuming and laborious.
The second way is to convey collection mode automatically using conveyer belt：Pass through the conveying being set to below tubular filter screen
The batting and dust collected and fallen from strainer are brought, but in actual use, most of batting and dust are in negative pressure
Still accumulation is attached on strainer under sucking action, and only fraction batting and dust can be fallen on conveyer belt, thus this kind
The collecting effect of collection mode is very undesirable.In addition to this, using the conveying device of conveyer belt, structure is complicated, operation stability
Also poor, batting and dust have part batting under the wind axis effect that vacuum suction generates and dust descends slowly and lightly to conveying device
Between each component, it will lead to motor when the batting and excessive dust accumulation between each component and damaged because resistance is excessive.In addition,
When the batting and excessive dust adsorbed on strainer, bulk batting is had, the mixture of mix dust is fallen on conveyer belt, from
And causing cassette tape phenomenon, i.e., bulk mixture is compressed in the gap between conveyer belt and Weaving device, so as to cause conveying
Band stops operating, and the motor for driving conveyer belt to rotate still is being run, this will lead to motor and damages because resistance is excessive.
