Description
Technical field
The invention belongs to tea packaging field, be specifically related to a kind of packaging machine of tea bag high-precision quantitative blanking system。
Background technology
Packaging machine of tea bag quantitative system precision in the market is not high, and from the measurement flow of market tea packaging machine and structural principle it can be seen that material is entered after metering by hopper the whole link of blanking mouth, the flowing of material is in free falling body state all the time。Therefore, the material of poor fluidity occurs that in above-mentioned metering system measuring accuracy situation poor, even blanking difficulty is very normal。Folium Camelliae sinensis weight ratio relatively gently and is Powdered, there is stronger adhesive force, cause that existing teabag chartered plane blanking measurement system Accuracy of Packaging does not reach the requirement of user, in real process, cause being scattered in a large number of Folium Camelliae sinensis, be unfavorable for high efficiency packaging, simultaneously, the amount of different blankings every time is also incomplete same, it is difficult to more accurate is quantitative, causes the inequality of product；It addition, long-play there is also the situation of blocking blanking mouth, it is difficult to realize continuous blanking and packaging。This is accomplished by a more accurate system and carries out the blanking system of powdered tea leaves。
Summary of the invention
The present invention to provide a kind of packaging machine of tea bag high-precision quantitative blanking system, to solve above-mentioned blanking difficulty, measure inaccuracy, cannot complete the technological deficiency of continuous blanking。
On the one hand, the present invention provides a kind of packaging machine of tea bag high-precision quantitative blanking system, it is characterised in that this system includes: for containing the hopper of material, be provided with material-stirring device in hopper；The quantitative chamber being arranged below being made up of housing at silo, metering screw is arranged in quantitative chamber, in the exit, one end in quantitative chamber, sealing gland leak-proof device is set, it is arranged below blanking mouth at leak-proof device, wherein, distance between the screw thread of metering screw is 5.5-7.0 centimetre, and the diameter of metering screw is 6.0-8.5 centimetre。
In some preferred modes, material-stirring device is made up of stepless speed-change motor and propeller device, controls agitating device by the outside stepless speed-change motor of hopper, drives material turning to prevent caking, increase material fluidity。Particularly preferred, the frequency of stepless speed-change motor is 50 hertz or to allow the rotating speed of stirring paddle be 30 turns per minute, so it is more beneficial for pulverous Folium Camelliae sinensis to overturn in hopper, fills the screw thread space on full quantitative screw rod, allow each screw thread space fill full tea-leaf power。
In some preferred modes, metering screw adopts the metering of positive displacement rotor, metering screw is provided with filling slot, filling slot is surrounded or space between two screw threads forms together with holding the object of metering screw space and the volume of determining filling slot by semi-circular cross-section。The material loading that the groove number that the packing dosage of material is rotated by metering rotor in the unit interval is multiplied by single filling groove is determined, carrys out accurate quantification by changing the swivelling chute number of metering screw in the unit interval。It is to say, the rotating speed of metering screw determines is positioned at the speed that material filling slot moves, the volume of unit filling slot determines the number of the built-in tea-leaf power of single groove。So determine to contain in single tea-bag the amount of tea-leaf power by two parameters of adjustment。In some preferred modes, when tea-leaf power is 80 order time, the rotating speed of quantitative screw rod is 15 turns per minute, the packaging effect reached。In some preferred modes, when tea-leaf power is 50 order time, the rotating speed of quantitative screw rod is 25 turns per minute, the packaging effect reached。80 orders mentioned here or 50 orders refer to that tea-leaf power can be entirely through the standard screen of 80 orders or the standard screen of 50 orders。
In other preferred modes, housing is the cavity holding metering screw with packaged material, material is entered in the measurement chamber of housing by hopper, after metering rotor measures, a number of packaged material being sent into blanking mouth, the metering cavity that housing is formed is the material channel connecting hopper with blanking mouth。
In other preferred modes, one sealing gland leak-proof device in metering cavity exit and installs valve, utilize the open and close of air compressor and stepless speed-change motor Collaborative Control valve, the charging action of each Folium Camelliae sinensis bag pack of accurate quantification, once a tea-bag has fed, valve closes the outlet of metering cavity, simultaneously as there is the effect of gas, it is possible to allow tea-leaf power when air pressure, order drops in tea-bag, decreases flying away and revealing of tea-leaf power。When operation, motor operates, and metering screw is collaborative with valve to be opened；Bag pack completes, and valve is closed rapidly, reveals without defective material, so circulates packaging。
In another preferred mode, blanking mouth is that material is transferred to the passage in packer bag pack package material by quantitative system, is provided with gas purge system, effectively prevents blanking mouth feed blocking and residual in it, improves tea-leaf power and enters the speed of tea-bag。
A kind of packaging machine of tea bag high-precision quantitative blanking system, is characterized in that: blanking system main body is made up of parts such as stepless speed-change motor, hopper, screw rod quantitative system and sealing gland leakage protective systems。Being furnished with material stirring and cavity in hopper, be provided with quantitative screw rod in cavity, cavity discharging place sets valve, and valve is controlled with controlling system by air compressor, and blanking system is connected to blanking mouth by leakage protective system。
The material metering mode of tea packaging machine adopts positive displacement rotor metering (see Fig. 1 and 2), clockwise/counterclockwise rotary electric machine can move along the axial direction left/right of metering rotor, and then can change material filling length in the filling slot (semi-circular cross-section) of metering rotor。The material loading being multiplied by single filling groove by the groove number of metering rotor rotation in the unit interval due to the packing dosage of material is determined, so, rotate metering screw and just can regulate the packaged dosage of material。The measurement flow of tea packaging machine is: packaged material is by hopper) enter in the measurement chamber of cavity, will a number of packaged material feeding gas sealing system after metering screw measures。Valve 4 is opened, and the material of a packing dosage enters in gas sealing system, and system remakes use, valve 4 is closed, cut off control body and gas sealing system, stop that defective material leaks into system, the packaged material of specified quantity is sent in tea packaging machine inner bag packaging material and completes blanking measurement function。
Beneficial effects of the present invention
Precision screw is quantitative, sealing gland leakage protective system completes each parts synergic adjustment, each action coordinates automatically, thus reaching best packaging efficiency, achieving teabag packaging without waste, high precision, indefectible brand-new new packaging concept, good product consistency, packaging efficiency is high, not only can save production cost, raising production efficiency, and its high-precision quantitative, high-air-tightness leakage protective system, establish Enterprise Credit image operator。
