Abstract
The utility model discloses a discharge constant flow improvement device for a feeder. A device for detecting height of materials is arranged on a quantitative pipe connected with a feeding hoister, and an electronic belt scale is arranged below the quantitative pipe; and the device for detecting the height of the material is a grating height detecting system, the grating height detecting system is connected with a programmable logic controller (PLC), and the PLC outputs signals to control speed change of the feeding hoister. According to the discharge constant flow improvement device for the feeder, three pairs of photoelectric switches for detecting the height of the material on the quantitative pipe in the prior art are changed into a grating capable of accurately detecting the height of the material. Through the device, the material of the quantitative pipe can be kept on a constant level, the flow at the outlet of the electronic scale is constant, and the material is not extruded into blocks.
Description
Technical field
The utility model relates to the equipment of tobacco manufacture field, especially refers to the modifying device of feeding machine discharging opening constant flow rate.
Background technology
In the existing cigarette fiber tow production, need to install one at operation inlets such as feeding in raw material, dry by the fire silk and overlap constant-flow device, with the stability of satisfied inlet mass flow.Shown in the following accompanying drawing 1 of this constant-flow device device structure, mainly form by feeding gig 3, quantity tube 1, photoelectric switch 2 and belted electronic balance 4.This equipment groundwork is: three pairs of photoelectric switchs 2 generally are installed on the quantity tube 1, are respectively high, medium and low bit switch, can detect the height of materials of three positions.The motor of feeding gig 3 is a variable frequency control, artificially presses the certain frequency operation through the height control feeding gig 3 of photoelectric switch 2 detection materials by middle control operator.Belted electronic balance 4 places quantity tube 1 below; Under normal circumstances; Belted electronic balance 4 flows can remain in the constant flow rate design objective scope; But because the running frequency of feeding gig 3 belongs to artificial control, can not follow the tracks of the actual height of material in the quantity tube 1 timely and effectively, have situation such as big perhaps quantity tube 1 putty of belted electronic balance 4 flow fluctuations.For example: quantity tube 1 material is less sometimes, and the motor running frequency of feeding machine 3 is slower simultaneously, may cause the short time fracture, makes belted electronic balance 4 flows produce fluctuation; Sometimes quantity tube 1 material is more, and the motor running frequency of feeding gig 3 is very fast simultaneously, easily the material in the quantity tube 1 is caused extruding, even causes quantity tube 1 putty.
The utility model content
To the weak point that exists in the prior art, the utility model provides a kind of feeding machine constant discharging flow modifying device, and this device can make the material of quantity tube remain on constant level, makes the constant flow of electronic scales outlet, and material is not squeezed into bulk.
For realizing above-mentioned purpose, the utility model technical scheme is:
A kind of feeding machine constant discharging flow modifying device wherein, is equipped with the device that detects height of materials on the quantity tube that joins with the feeding gig, belted electronic balance is installed on the quantity tube below; The device of said detection height of materials is a grating height detection system, and this grating height detection system connects the PLC controller, PLC controller output signal control feeding gig velocity variations.
The usefulness of technique scheme is:
The utility model feeding machine constant discharging flow modifying device replaces with the grating that can accurately detect height of materials with three pairs of photoelectric switchs that detect height of materials on the quantity tube in the prior art; Through optical grating detection technology, can accurately detect the height of materials in the quantity tube.Through the pid control circuit in the PLC controller, can realize that height of materials remains on constant level in the quantity tube.The material discharging can realize that the flow of belted electronic balance remains in the constant flow rate design objective scope in the quantity tube behind belted electronic balance.The material that has solved in the quantity tube causes extruding owing to too high, thereby and causes the phenomenon of quantity tube putty.The utility model feeding machine constant discharging flow modifying device tobacco manufacture field at home still belongs to blank, and the Study on Technology achievement will have better practicability and generalization.
Description of drawings
Fig. 1 is a prior art feeding machine constant discharging flow modifying device structural representation;
Fig. 2 is the utility model feeding machine constant discharging flow modifying device structural representation;
Fig. 3 is the utility model grating pid control circuit scheme drawing.
The specific embodiment
Combine accompanying drawing and embodiment that the utility model is described at present.
Feeding machine constant discharging flow modifying device as shown in Figure 2 wherein, is equipped with the grating 2 that detects height of materials on the quantity tube 1 that joins with feeding gig 3, belted electronic balance 4 is installed on quantity tube 1 below.This grating height detection system connects the PLC controller, PLC controller output signal control feeding gig velocity variations.
The PLC controller is used its functional language and is designed pid control circuit and control in internal functional blocks.The utility model pid control circuit mainly is made up of feeding machine variable frequency control loop; This feeding machine variable frequency control loop connects a grating height detection system, and is as shown in Figure 3, and setting the grating height value is numerical value A; Through grating height detection system grating 2 detected actual height values (numerical value B) are input in the PLC controller; Through the PID computing, PLC controller output control signal is controlled the frequency converter of feeding gig 3, thereby controls the variation of rate of feeding through the output of frequency converter; Height of materials with in the assurance quantity tube 1 remains on constant level, and realizes the controlled reset of grating height in the quantity tube 1.
Above embodiment is merely the technological thought of explanation the utility model; Can not limit the protection domain of the utility model with this; Every technological thought that proposes according to the utility model, any change of on the technical scheme basis, being done all falls within the utility model protection domain.
