Description

Dust removal device for air jet loom

Technical Field

The utility model relates to a weaving equipment field, especially a dust collector for air jet loom.

Background

Air jet looms are shuttleless looms that use a jet of air to pull the weft yarn through the shed. The operating principle is that air is used as weft insertion medium, the ejected compressed airflow generates friction traction force to weft yarn to pull the weft yarn, the weft yarn is taken through a shed, and the purpose of weft insertion is achieved through the jet flow generated by air jet.

In the weaving process of the air jet loom, the heald frame repeatedly lifts and returns healds, the reed quickly reciprocates to beat up, the arrangement density of the warp yarns is high, so that severe friction force is generated between the warp yarns and the warp yarns, between the healds and the reed, hairiness and sizing on the surface of the warp yarns fall off to form a large amount of floating dust, and the floating dust can float in a textile workshop to pollute the working environment of the textile workshop and even explode when the density reaches a certain concentration. Therefore, the dust removing device is widely used in a textile workshop. However, the existing dust removal device only simply pumps the hairiness in the workshop to the space outside the workshop, the pollution to the environment still exists, and the hairiness is not recycled, so that the existing green environmental protection concept is not met.

SUMMERY OF THE UTILITY MODEL

In view of the above insufficiency, the utility model aims to provide a dust collector for air jet loom can realize the absorption retrieval and utilization to showy filoplume in the weaving workshop.

In order to achieve the above purpose, the technical scheme of the utility model is that:

a dust removal device for a jet loom comprises a dust collection box, wherein an inlet is formed in the upper portion of the dust collection box and is connected with a dust hood through a pipeline, the dust hood is arranged above the jet loom, an air chamber opposite to the inlet is formed in the dust collection box, a plurality of vent holes are uniformly formed in the upper portion of the air chamber, an exhaust fan is connected to the lower portion of the air chamber, a first lead screw is horizontally and rotatably arranged in the dust collection box, one end of the first lead screw extends out of the dust collection box and is connected with a first motor in a transmission mode, a first moving block is screwed on the first lead screw, two ends of the first moving block are in smooth abutting connection with the side wall of the dust collection box, and; the dust collection box is characterized in that a second lead screw is longitudinally and rotatably arranged in the dust collection box, one side of the second lead screw, which is far away from the air chamber, is connected with a second moving block in a threaded mode, two ends of the second moving block are in smooth butt joint with the side wall of the dust collection box, the second moving block is horizontally arranged right opposite to one side of the air chamber, a comb reed which can be inserted into the hairbrush is arranged, an outlet is formed in the bottom of the dust collection box, and a valve which is used for sealing the outlet.

Further, the valve is a weight valve.

Furthermore, a telescopic cylinder is horizontally arranged beside the dust collection box, a telescopic rod of the telescopic cylinder penetrates through the side wall of the dust collection box and then extends into the dust collection box, and the end part of the telescopic rod of the telescopic cylinder is fixedly connected with a push plate arranged close to the bottom surface of the dust collection box.

The working principle is as follows: when the air jet loom works, the exhaust fan works, negative pressure is generated in the air chamber, then negative pressure is generated in the dust collection box, hairs generated by the air jet loom are sucked into the dust collection box through the dust hood arranged at the upper part of the air jet loom, and then the hairs are blocked by the top part provided with the vent hole at the upper part of the air chamber and are accumulated at the top part of the air chamber. When the hairiness is accumulated to a certain amount, the first motor drives the first screw rod to rotate back and forth, so that the first moving block is driven to move on the screw rod in a reciprocating mode, the hairbrush brushes the upper surface of the air chamber in the reciprocating moving process, and the hairiness accumulated on the air chamber is taken away by the hairbrush. And then when the hairbrush with the hairiness is close to the second comb reed, the second motor drives the second lead screw to rotate so as to enable the second moving block to move up and down, in the process that the second moving block moves up and down, the hairiness on the hairbrush is combed down and falls onto the valve by the comb reed, and after a certain amount of accumulated hairiness is accumulated, a worker opens the valve, and the hairiness is discharged from the dust collection box.

Has the advantages that: through the structure, hairiness generated by the air jet loom can be timely cleaned and intensively recovered, and the working environment of a workshop is effectively improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

A dust removing apparatus for an air jet loom as shown in fig. 1 includes a dust box 1, an inlet 101 is provided at an upper portion of the dust box, a duct 2 is connected to the inlet, and a dust hood 4 provided above the air jet loom 3 is connected to the other end of the duct. In addition, a wind chamber 5 is formed in the dust box by separating the inner space thereof by a steel plate. Specifically, the air chamber is arranged opposite to the inlet, and a plurality of vent holes 501 which enable the air chamber to be communicated with the dust collection box are uniformly formed in the upper part of the air chamber. Meanwhile, the lower part of the air chamber is provided with an exhaust fan 6 communicated with the air chamber, negative pressure is generated in the air chamber through the exhaust fan, and then hairs entering the dust collecting box from the inlet are absorbed on the upper surface of the air chamber. In addition, the hair on the surface of the dust collection box can be cleaned at regular time, so that good ventilation performance of the ventilation hole is ensured. A first screw rod 7 is horizontally and rotatably arranged in the dust collection box, a first moving block 8 is screwed on the first screw rod, the width of the first moving block is the same as the inner width of the dust collection box, namely, two ends of the first moving block are abutted against the inner wall of the dust collection box in a sliding fit manner. In addition, one end of the first screw rod penetrates through the dust collection box and then is in transmission connection with a first motor 9 fixedly arranged on the dust collection box. In the production process, the first motor drives the screw rod to rotate in the forward and reverse directions. Meanwhile, a brush 10 abutting against the upper surface of the air chamber is further arranged on the lower surface of the first moving block capable of moving back and forth on the first screw rod.
