Provide the user that this equipment also can not comprise compressor under the situation of atomizing air.The fabric injector has a small-sized hopper, so the raw material supply that it can use separately or install on handcart is used.Another scheme can have an independently compressor, itself has the motor of the independent operation that is used for raw material and air.
Have been found that peristaltic pump can produce special vibration, this vibration has improved for example flow of fabric of high viscosity feedstock by binding and self-cleaning hopper between loose flexible pipe and high viscosity feedstock.This pump can turn round forward or backwards, and antiport wherein is used to empty flexible pipe or transferring raw material.
Flexible pipe maintaining body on the peristaltic pump is formed by connecting flexible pipe, flexible pipe retainer plate, installing plate and retainer screw.The flexible pipe that has joint slides on each end of flexible pipe retainer plate.The flexible pipe retainer plate is fixed to installing plate or surface by fixator, passes the surface of installing plate for use in access and hose coupling is outstanding.The flexible pipe retainer plate supports the down load that is applied by peristaltic pump, and installing plate or surface will connect flexible pipe keep suitable alignment in pump.When cooperating flexible pipe to be connected by nipple, the profile of assembly parts (for example hexagon) matches with the opening on installing plate or surface can prevent the rotation of assembly parts.
In peristaltic pump of the present invention, the distance that flexible pipe is stretched is set as variable or adjustable, therefore can obtain variable flow velocity.Flow furthers pipeline by one or changes away from the adjuster of rotor center.When the distance D of leaving mounting points increases, thereby flexible pipe tension force T increases the leakage QL that reduces roller contact point place.Relation between output/input pressure P, pipeline or flexible pipe tension force T, fluid viscosity V and pipeline/hose material is selected will determine the efficient of pump.Because these factors, pump can be arbitrarily in 0 to 100% running of volumetric efficiency.
When injector or distributing valve were closed (no raw material flows) and pump running, seepage volume QL equaled displacement volume (2Q * revolutions per minute) to prevent overvoltage.The needs to expensive motor rotary speed and/or closing control have been eliminated in the design of self compensation pump, have also eliminated the motor starting (allowing 15 amperes of outputs of use standard) of high electric current.
These and other objects of the present invention and advantage will more fully show from description taken together with the accompanying drawings subsequently, and wherein identical Reference numeral is represented same or analogous parts in whole a plurality of views.

The specific embodiment
The present invention is generally designated 10, is small-sized, a relatively inexpensive and self-contained fabric spraying device.Handcart 12 comprises the adjustable peristaltic pump of one or more flows 14, motor 16 (electronic or gasoline driven), raw material supply bucket 18 and volume control device 20 for example injector or distributing valve.A both-end motor shaft can also be provided, and wherein an end drives peristaltic pump 14, and the other end drives an air compressor 22.
As shown in Figure 1, provide the user that this equipment also can not comprise compressor in the situation of atomizing air.The fabric injector has a small-sized hopper 20a, thus it can use separately or on handcart fixing raw material supply use.Another program can have an independently compressor, itself has the motor of the independent operation that is used for raw material and air.
Have been found that peristaltic pump can produce special vibration, this vibration has improved for example flow of fabric of high viscosity feedstock by binding and self-cleaning hopper 18 between loose flexible pipe 24 and high viscosity feedstock.This pump 14 can turn round forward or backwards, and antiport wherein is used to empty flexible pipe or transferring raw material.
Flexible pipe maintaining body 26 on the peristaltic pump 14 is formed by connecting flexible pipe 28, flexible pipe retainer plate 30, installing plate 32 and retainer screw 34.The flexible pipe that has joint 36 slides on each end 30a of flexible pipe retainer plate 30.Flexible pipe retainer plate 30 is fixed on installing plate or the surface 32 by fixator 34, and hose coupling 36 is given prominence to and passed the surface of installing plate 32 for use in access simultaneously.Flexible pipe retainer plate 30 supports the down load that is applied by peristaltic pump 14, and installing plate or surface 32 will connect flexible pipe 28 keep suitable alignment in pump 14.When cooperating flexible pipe 38 to be connected by nipple 38a, the profile of assembly parts 36 (for example hexagon) matches with the opening 32a on installing plate or surface 32 can prevent the rotation of assembly parts 36.
In peristaltic pump 14 of the present invention, the distance D that flexible pipe 28 is stretched is set as variable or adjustable, therefore can realize variable flow velocity.Flow changes by adjuster 40, and described adjuster 40 is by raising about support 12, rotor 42 and roller 44 or reducing installing plate 32 pipeline 28 is furthered or away from the center of rotor 42.
Preferred adjuster 46 is variable force device flows to be used to change the tension force on the pipeline 28 and therefore to cause.Such device can be fluid (gas or liquid) cylinder, and if desired, it can have an independent pressure regulator 48, is used to control the intensity of force that applies and therefore controls flow velocity.Adjuster 46 also can be a solenoid, adjustable springs or other forcer well known in the art.
When the distance D of leaving fixing point increases, thereby flexible pipe tension force T increases the leakage QL that reduces roller 44 contact point places.Relation between output/input pressure P, pipeline or flexible pipe tension force T, fluid viscosity V and pipeline/hose material is selected will determine the efficient of pump.Because these factors, pump can be arbitrarily in 0 to 100% running of volumetric efficiency.
When injector or distributing valve 20 were closed (no raw material flows) and pump 14 runnings, seepage volume QL equaled displacement volume (2Q * revolutions per minute) to prevent overvoltage.The design of self compensation pump has been eliminated the expensive motor rotary speed and the needs of closing control, has also eliminated the motor starting (allowing 15 amperes of outputs of use standard) of high electric current.
