A kind of automatic regulation system for pressure that is used for the single-face corrugation machine pressure roll
Technical field:
The utility model relates to the corrugated board production technical field, refers in particular to a kind of automatic regulation system for pressure that is used for the single-face corrugation machine pressure roll.
Background technology:
Single face corrugated board is to fashion into required corrugation shape by corrugating medium through the corrugation roller of single-face corrugation machine, and be coated with the formulated sticker of starch in the corrugation crest, is bonded with facial tissue under the pressure of pressure roll again.The setting pressure of pressure roll is directly connected to the quality of bonding quality, in process of production, and under the more satisfactory state, the corresponding different speed of a motor vehicle requires different setting pressures, if pressure roll pressure is too little, can cause bonding bad the coming unstuck of core paper and facial tissue, form empty the subsides, directly produce waste product.If pressure roll pressure is too big, it is quick-fried to cause core paper and facial tissue to be pressed, and squishes phenomenon, equally also can directly produce waste product.Therefore the control of the appropriateness of described pressure roll pressure is the key that can product qualified, existing corrugated paper board production line, the pressure roll pressure control technology measure of single-face corrugation machine is to determine by manual measurement single-faced corrugated paper board finished product whether described pressure is suitable, this measure has its weak point: when finding defective work, produced a large amount of defective works.The pressure of pressure roll is to depend on the promotion of cylinder and keep fully in process of production, because cylinder itself has compressibility, the cumulative errors of driving member change in the middle of some in addition, cause each uncertainty, inexactness of adjusting and not directly perceived, therefore present corrugated board production device is because this adjustment inconvenience is higher to the percent defective that makes cardboard.
Summary of the invention:
The purpose of this utility model is to provide a kind of can regulate pressure roll pressure in real time, reduces the automatic regulation system for pressure that is used for corrugated paper board production line single-face corrugation machine pressure roll of percent defective.
For achieving the above object, technical scheme provided by the utility model is: a kind of automatic regulation system for pressure that is used for the single-face corrugation machine pressure roll, it includes electricity-controlled pneumatic ratio valve, velocity sensor, data acquisition module, the PLC Programmable Logic Controller, analog output module, pressure cylinder, exit roller, wherein, exit roller is installed on the paper bowl bearing, the paper bowl bearing is installed on the frame, velocity sensor is installed on the exit roller side, and velocity sensor and data acquisition module, the PLC Programmable Logic Controller, analog output module, electricity-controlled pneumatic ratio valve is connected successively, electricity-controlled pneumatic ratio valve after the series connection is installed on the pressure cylinder of single-face corrugation machine, the piston rod of pressure cylinder is connected with pressure roller seat on the frame, on the pressure roller seat pressure roll is installed.
The utility model is after having adopted such scheme, by velocity sensor, the automatic control system that PLC Programmable Logic Controller etc. constitute, wherein, velocity sensor is transferred to Programmable Logic Controller by data acquisition module in real time with the single-face corrugation machine speed of production, analyze computing by Programmable Logic Controller by the software of establishment, the speed data of gathering is carried out computing by the relational expression of predefined speed data and output pressure, the corresponding corresponding pressure of different speed, operation result is passed to analog output module, by analog output module by the control electricity-controlled pneumatic ratio valve pressure size of coming the controlled pressure cylinder, thereby reach the purpose of regulating pressure roll pressure, after adopting this programme, the pressure that can guarantee pressure roll all is controlled in the optimal pressure limit in the different speed of a motor vehicle, thereby reaches the purpose that reduces waste product.

The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing 1 and accompanying drawing 2, preferred embodiment of the present utility model is: the described automatic regulation system for pressure that is used for the single-face corrugation machine pressure roll of present embodiment, it includes electricity-controlled pneumatic ratio valve 1, velocity sensor 2, data acquisition module 3, PLC Programmable Logic Controller 4, analog output module 5, pressure cylinder 6, exit roller 7, wherein, exit roller 7 is installed on the paper bowl bearing 8, paper bowl bearing 8 is installed on the frame, velocity sensor 2 is installed on exit roller 7 sides, and velocity sensor 2 and data acquisition module 3, PLC Programmable Logic Controller 4, analog output module 5, electricity-controlled pneumatic ratio valve 1 is connected successively, electricity-controlled pneumatic ratio valve 1 after the series connection is installed on the pressure cylinder 6 of single-face corrugation machine, the piston rod of pressure cylinder 6 is connected with pressure roller seat 9 on the frame, and pressure roll 10 is installed on the pressure roller seat 9.
Its operation principle is: velocity sensor 2 is contained on exit roller 7 sides that can reflect the variation of unit Corrugating Machine speed of production, facial tissue must pass through exit roller 7, under the drive of facial tissue, so just can reflect the variation of unit Corrugating Machine speed of production, velocity sensor 2 is gathered the information of single-face corrugation machine speed of production in real time, and become the signal of telecommunication to reach data acquisition module 3 information translation, data acquisition module 3 is delivered in the PLC Programmable Logic Controller 4 after the signal of telecommunication that receives is reduced into velocity information, PLC Programmable Logic Controller 4 is analyzed computing by the software of establishment, the speed data of gathering is carried out computing by predefined speed data and output pressure relational expression, the corresponding corresponding pressure of its different speed, operation result is passed in the analog output module 5 with electrical signal form, analog output module 5 is according to the instruction control electricity-controlled pneumatic ratio valve 1 of PLC Programmable Logic Controller 4, make the pressure of pressure cylinder 6 change increase or minimizing with the single-face corrugation machine speed of production, promote 9 motions of pressure roller seat at pressure cylinder 6, the pressure of pressure roll 10 is either large or small to be regulated in real time, and what the control of electricity-controlled pneumatic ratio valve 1 was adopted is control automatically in real time.Speed data of setting and output pressure ratio relation are determined as required by the user, the utility model can be equipped with touch-screen, setting speed data and output pressure relational expression data are imported thus, perhaps rewrite the speed data and the output pressure relational expression data of former setting thus, very convenient, can see simultaneously on-the-spot pressure adjusting situation, very directly perceived.When the velocity amplitude of gathering is in when constant, system keep-ups pressure constant, when the velocity amplitude of gathering changes, PLC Programmable Logic Controller 4 sends instruction to analog output module 5, start electricity-controlled pneumatic ratio valve 1 action, thereby make the pressure of pressure cylinder 6 increase or reduce to reach the purpose of regulating pressure roll 10 pressure.The pressure of pressure roll 10 can accurately be regulated automatically, guaranteed the production good quality also of corrugated board energy continous-stable.
The embodiment of the above is the preferred embodiment of the utility model only, is not to limit practical range of the present utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the present utility model.
