Description

Pneumatic burr sucking device of longitudinal sewing machine

Technical Field

The utility model relates to a fabrics processing longitudinal joint machine field, more specifically says, it relates to a pneumatic wool edge material device that inhales of longitudinal joint machine.

Background

The towel is wrapped the edge and needs to excise unnecessary deckle edge material before, and it is at scissors below position setting one suction cylinder among the current equipment, and suction cylinder bottom is connected industry electric vacuum cleaner, starts electric vacuum cleaner and produces certain suction at the top port that inhales the feed cylinder, inhales the collection with the leftover bits of cloth walking in excision. The electric dust collector has large volume, cannot be directly placed below the equipment, is generally placed at a far position on the side of the equipment, needs to be communicated with a long pipe, has attenuated suction force, can accumulate and block a pipeline due to burr materials, generates heat when a motor of the dust collector is overloaded, is easy to damage and generates fire risks. Moreover, when the electric dust collector works, the sound is about 85 decibels, the noise is very high, and the working environment is polluted; meanwhile, the industrial electric dust collector has one thousand yuan and higher price.

The longitudinal sewing machine is communicated with an air pipe, the position of the edge of the towel needs to be detected before the edge folding sewing, the towel blank is ensured to pass through the specified position of the longitudinal sewing machine, and the air is blown towards the pile loop in order to accurately detect the position of the pile loop of the towel; the other is that the edge is sewed to blow against the towel edge, so that the looped pile is not sewed and pressed in the edge. Therefore, the applicant designs and develops a pneumatic wool edge material sucking device by using the convenience of the device with an air passage.

Disclosure of Invention

Not enough to prior art exists, the utility model aims to provide a solve the pneumatic deckle edge material device that inhales of longitudinal joint machine of above-mentioned problem utilizes equipment self gas circuit facility, blows to the suction that produces the drive air current of inhaling the feed cylinder, and the deckle edge material after directly will cuting is sent into and is inhaled the terminal sack of feed cylinder, simple structure, effective, reduction equipment cost.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the pneumatic burr material device that inhales of longitudinal sewing machine, including being located the material suction tube of trimming machine scissors below, inhale material suction tube top one avris and be equipped with the apron that shelters from partial nozzle, trompil on the apron, the trachea of intercommunication compressed air source is given vent to anger and is held in stretching into the material suction tube through the hole, and the material suction tube bottom cup joints the sack.

The utility model discloses further improve technical scheme and be, apron inboard erects connects riser 5. Can block the falling wool edge material from entering the material suction barrel along the same direction.

The utility model discloses further improve technical scheme be, in the trachea inserts the suction cylinder perpendicularly, the trachea gas outlet is higher than the riser bottom.

The utility model discloses further improve technical scheme and be, install solenoid valve, choke valve on the trachea. When the shearing device does not need to work, the switch is controlled by the electromagnetic valve; the throttle valve controls the flow rate of the inlet air and adjusts the suction force generated in the suction cylinder.

The utility model discloses further improve technical scheme and be, solenoid valve, choke valve set up on being close to the trachea of inhaling feed cylinder one end.

The utility model discloses beneficial effect:

the utility model discloses utilize the trachea to high-speed jet compressed air in inhaling the feed cylinder, form the efflux in the trachea export, produce the entrainment and flow under the entrainment effect for air around the trachea export is constantly taken out and is inhaled away, makes the pressure drop that adsorbs the intracavity to below the atmospheric pressure, forms certain negative pressure, is inhaling the feed cylinder mouth and produces suction. The sheared rough edge materials are sucked into the suction barrel in time and then fall into the pocket due to gravity.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the inverted structure of FIG. 1;

fig. 3 is a working principle diagram of the suction cylinder.

Detailed Description

As shown in fig. 1 and 2, the utility model discloses a be located the feed cylinder 1 that inhales of trimming machine scissors 6 below, an avris in 1 top of the feed cylinder of inhaling is equipped with the apron 2 that shelters from partial nozzle, the trompil is gone up to the

apron

2, 3 ends of giving vent to anger of trachea that communicate compressed air source stretch into the feed cylinder 1 perpendicularly through the hole in, 2 inboard vertical joints riser 5 of apron, 5 bottoms of riser stretch into in the feed cylinder, 3 gas outlets of trachea are higher than 5 bottoms of riser, 1 bottoms of feed cylinder cup joint sack 4, be close to on the trachea of connecting the air source and inhale feed cylinder one end and install solenoid valve, choke.

The operating principle is as shown in fig. 3, compressed air is injected into the space of the suction barrel below the cover plate at a high speed from the air pipe, jet flow is formed at the outlet of the air pipe, entrainment flow is generated, air around the outlet of the spray pipe is continuously sucked away under the action of entrainment, the pressure in the suction barrel is reduced to be below atmospheric pressure, certain negative pressure is formed, the suction barrel opening generates suction, the burr materials cut by the upper scissors enter the suction barrel under the action of suction, and the burr materials fall into the cloth bag according to self gravity after entering the suction barrel.
