Abstract
The utility model relates to a diffusion negative-pressure type vacuum suction-head. The diameter of an air conveying channel 3 is reduced from an air inlet end 5 to an air exhausting end 2 in sequence and is increased in sequence from a balance section, and a negative-pressure hole 1 connected with a suction disk 7 is communicated with the air exhausting end.
Description
The utility model relates to a kind ofly draws the device of object by negative pressure, specifically is used for the suction nozzle that the molded equipment of disposable tableware is drawn goods.
In existing disposable tableware former, vavuum pump, vacuum tank and corresponding pipeline and control device all are installed basically, utilize by the negative pressure that vavuum pump produced and draw goods in the mould.Its suction nozzle only plays the effect that connects sucker and negative-pressure gas is passed through.There are deficiencies such as complex structure, expense costliness, wayward, maintenance difficult, noise be bigger in this equipment.
The purpose of this utility model is exactly to overcome the deficiency that exists in the background technology, and a kind of negative pressure equipment simplification, expense reduction, effective suction nozzle of negative pressure of making is provided.
The technical solution that realizes above-mentioned purpose is such:
This diffusion suction type vacuum cups comprises suction nozzle itself, and it mainly is to be provided with gas distribution channel in the suction nozzle body, and the negative pressure hole that links to each other with sucker communicates with the exhaust end of gas distribution channel.Said gas distribution channel is reduced successively by the diameter of inlet end to exhaust end, increases successively again behind a balancing segment.Be connected with appendix and blast pipe on the suction nozzle.Negative pressure hole links to each other with sucker by suction tube.
Accompanying drawing is a structural representation of the present utility model.
As shown in drawings, be provided with the gas channel 3 of a convergent-divergent channel shape in these suction nozzle 4 bodies, be connected with inlet end 5, appendix 8 and exhaust end 2, blast pipe 9 respectively at the two ends of this gas channel 3.Said gas channel 3 reduces successively from the diameter of inlet end 5 to exhaust end 2, and through increasing successively again behind the balancing segment, promptly two microcephalies are horn-like to what push up.Also be communicated with a negative pressure hole 1 at exhaust end 2, this negative pressure hole 1 links to each other with sucker 7 by suction tube 6, that is exhaust end 2 directly communicates with sucker 7.Said blast pipe 9 connects silencer and enters airspace.Said appendix 8 directly is connected with air compressor or air accumulator.
When compressed air when inlet end 5 feeds because the diameter of gas channel 5 diminishes gradually, and make air velocity be increased to the critical value Pk of balancing segment gradually, enter diameter then and become big gas channel 3 gradually, diffusion appears in air-flow also increases its speed rapidly.Negative pressure will be produced at negative pressure hole 1 place that communicates with exhaust end 2 so, thereby the goods that are positioned at mould can be drawn by suction tube 6 and sucker 7.
Because structural design of the present utility model, can replace the existing numerous and jumbled equipment such as vavuum pump, vacuum tank that use fully, only need import compressed air and can reach desirable absorption effect, greatly reduce cost of equipment, also make control become more simple, be highly suitable in the disposable tableware make-up machine and other utilizes negative pressure to draw in the equipment of product to install and use.
