Description
Technical field
The invention belongs to sewing machine technique field, is related to a kind of chip suction device of sewing machine, particularly a kind of sewing machine inhales bits
The air intake assembly of device.
Background technology
Sewing machine can also produce many cloth bits waste materials, the end of a thread chip in the course of the work, if processed not in time, easily right
Sewing machine runs well and affects.In order to solve this problem, the device for processing chip can be set on sewing machine.
For example, Chinese utility model patent (authorized announcement date：2012.9.12；Authorization Notice No.：CN 202430458 U)
A kind of pneumatic dust collect plant of industrial sewing machine is disclosed, and air draught dress is considered to be worth doing including the pneumatic type cloth for being connected to sewing machine needle board lower end
Put, be connected to pneumatic type the end of a thread air intake device of aspiration channel rear end in thread trimmer group, pneumatic type cloth bits air intake device and pneumatic type
The end of a thread air intake device is connected with cloth retracting device, the action of pneumatic type cloth bits air intake device and pneumatic type the end of a thread air intake device
By same solenoid valve control.
Wherein pneumatic type cloth bits air intake device is：Material-falling hopper is provided with below the needle plate of overedger, is located at below material-falling hopper
Bend pipe, flexible pipe, suction tube are in turn connected to form a suction passage, and suction tube is connected with air intake duct, one end of air intake duct with enter
One end of tracheae connect to form inlet channel, the other end and flexible pipe and the feed pipe on retracting device to be in turn connected to form charging logical
Road, suction passage and inlet channel, feeding-passage and retracting device intracavity inter-connection, on the other end and magnetic valve of air inlet pipe
One of gas outlet be connected.
But, in the dust collect plant, by air inlet pipe air inlet, its air inflow only leans on air inlet to pneumatic type cloth bits air intake device
Pipe is supplied, and its air inflow is less, so as to its suction bits effect is poor.
The content of the invention
The purpose of the present invention is there are the problems referred to above for existing technology, it is proposed that a kind of larger sewing machine of air inflow
The air intake assembly of bits-suction device.
The purpose of the present invention can be realized by following technical proposal：
The air intake assembly of chip suction device of sewing machine, is arranged at chip suction device of sewing machine, and bits-suction device includes suction tube, institute
The air intake assembly stated includes being connected to suction tube side part and cylindrical air inlet support, and having in described air inlet support is used for
To suction tube produce negative pressure inlet channel, it is characterised in that the air intake assembly also include be connected to air inlet stent side portion and
Cylindrical tonifying Qi part, the two ends of described tonifying Qi part are connected with extraneous and inlet channel respectively, described tonifying Qi part bag
Cylindrical muffler is included, the two ends of the muffler are connected with extraneous and inlet channel respectively.
During use, inlet channel is ventilated, the air-flow of quick flowing produces negative pressure in suction tube so that suction tube
Suction out cloth bits.As tonifying Qi part is additionally arranged in this air intake assembly, tonifying Qi part is connected with inlet channel, and inlet channel is also in tonifying Qi
Negative pressure is produced at part so that the air outside tonifying Qi part flows through tonifying Qi part hence into suction tube, increases this air intake assembly
Air inflow, so as to improve chip suction device of sewing machine suction consider to be worth doing effect.But due to tonifying Qi part operationally, air-flow enters tonifying Qi
Noise can be produced during part, and noise can make air intake assembly shake more severe, bits are inhaled so as to have impact on.So, in this air inlet group
Muffler is set in part so that, while ensureing to increase air inflow, its noise content is less, that is to say, that in this group for this component
In part, by arranging tonifying Qi part and the muffler in tonifying Qi part simultaneously, it is ensured that the increase air inflow that this component can be stable.
In the air intake assembly of above-mentioned chip suction device of sewing machine, the outer end of described muffler is coaxially provided with benefit in a tubular form
Gas joint, be coaxially provided with the outer end of the tonifying Qi joint radial inward diminution in cone shape spigot surface.In tonifying Qi joint
Outer end arranges spigot surface, so as to increase the contact surface of tonifying Qi joint and air so that the more convenient entrance tonifying Qi joint of air,
So as to increase air compensation, and then the air inflow of increase suction tube, therefore so that inhale bits effect more preferable.
In the air intake assembly of above-mentioned chip suction device of sewing machine, the inner of described tonifying Qi joint has stretches out and in a tubular form
Extension, the extending area inside muffler with muffler be coaxially disposed and between extension and muffler madial wall have
There is gap.The air-flow entered from tonifying Qi joint can produce certain noise, and a portion noise is absorbed by muffler, another portion
Noise recoils to tonifying Qi joint.Therefore, extension is set so that the noise of most of resilience all enters entering department and muffler
It is eliminated between madial wall.Likewise, eliminating the noise of air-flow, it is to avoid noise produces effect of jitter to air intake assembly and inhales bits,
So that it is more stable to inhale bits effect.
Valve is fixed with the air intake assembly of above-mentioned chip suction device of sewing machine, described air inlet support, described enters
Gas mixing pipe be coaxially provided with gas support also, the two ends of the gas mixing pipe are connected with the inner of tonifying Qi part and suction tube respectively, institute
State inlet channel is formed with negative pressure hole, described valve and negative pressure hole on the wall of gas mixing pipe side.It is separately provided gas mixing pipe so that negative
The processing in pressure hole is more convenient.
In the air intake assembly of above-mentioned chip suction device of sewing machine, described gas mixing pipe is arranged with the grafting of air inlet support.Due to
Gas mixing pipe grafting is arranged in air inlet support, can adjust the inserting depth of gas mixing pipe as needed, so as to adjusting gas mixing pipe and inhaling
The distance between expects pipe stretches into the length of suction tube, adjusts then the air inlet in suction tube so that inhale bits effect more preferable.
It is provided between the air intake assembly of above-mentioned chip suction device of sewing machine, described gas mixing pipe and air inlet support for making
The circumferentially positioned position limiting structure of gas mixing pipe and air inlet support.Between gas mixing pipe and air inlet support, position limiting structure is set so that when
When adjusting the position of gas mixing pipe, suction nozzle is facilitated to be directed at negative pressure hole always, it is ensured that air inlet effect and suction bits effect.
In the air intake assembly of above-mentioned chip suction device of sewing machine, described position limiting structure includes being arranged on convex on gas mixing pipe
Block and on air inlet support along air inlet support is axially arranged and the groove in strip, described projection and groove match.
When the position of gas mixing pipe is adjusted, projection is embedded in groove always.
Compared with prior art, the air intake assembly of this chip suction device of sewing machine due in air intake assembly arrange tonifying Qi part,
And muffler is set in tonifying Qi part so that the air inflow of the increase bits-suction device that this component can be stable.
