Description
Technical field
The present invention relates to a kind of film punching machine control system, belong to agricultural mechanical field.
Background technology
In order to improve the quality and yield of fruit, orchard workers have the mulch film of reflecting effect in fruit tree lower berth setting tool, utilize mulch film also can be subject to the irradiation of sunlight towards the ground side to the reflection guarantee lower part of a tree fruit of sunlight.But be paved with mulch film under tree after, there will be three problems, one is that tree root gas permeability is bad; Two is that rainy period and the rear rainwater that rains can not penetrate into underground in time; Three is that rainwater damages evil effect to mulch film.In order to address this problem, just need on mulch film, get size and the rational aperture of spacing.Traditional hole-ground film mode is manual punching, and the hole size be up to differs, irregular arrangement, can affect the lighting effect of mulch film like this, and perforating efficiency is low.Therefore, be necessary to develop and can improve perforating efficiency, do not affect again hole-ground film equipment that is ventilative and reflecting effect, control system is its key components.Control system is in order to coordinate winding up roller, porcupine roller and felt roll organically, and in process winding up roller rotation process, the radius of gyration constantly changes brought problem.
Summary of the invention
The technical problem to be solved in the present invention is, in order to ensure that the aperture of mulch film being got hole meets the requirements, is evenly distributed, perforating efficiency is high, needs to control puncher winding up roller rotating speed, porcupine roller rotating speed, ensures that the linear velocity of mulch film is consistent with the linear velocity at porcupine roller needle point place.Control the lifting opportunity of felt roll, ensure that felt roll could rise when the linear velocity of mulch film is consistent with the linear velocity at porcupine roller needle point place.
Needle-type film punching machine control system arranges module, speed measurement module, control signal module, felt roll control module, porcupine roller frequency transformer control module and winding up roller frequency transformer control module by puncher control module, speed and forms.
When working beginning, first Negotiation speed arranges the linear velocity of mulch film when module installation punches, and then utilizes control signal module to send and starts punching signal.After puncher control module receives enabling signal, start frequency converter and motor with default frequency, at this moment the actual linear velocity of mulch film does not also have and the linear velocity that sets reaches synchronous.After motor rotates, puncher control module Negotiation speed measurement module collects current linear velocity data, and utilizes current linear velocity data to calculate the current diameter of winding up roller, calculates the output frequency of frequency converter according to winding up roller diameter and porcupine roller diameter.The frequency converter output frequency calculated is transferred to porcupine roller frequency transformer control module and winding up roller frequency transformer control module by puncher control module, and the operating frequency of two frequency converters that upgrade in time.After porcupine roller frequency converter and winding up roller frequency converter operating frequency obtain upgrading, actual linear velocity and arrange linear velocity and reach synchronous, rises felt roll, starts punching.After puncher control module receives stop signal, first fall felt roll, then stop the work of frequency converter and motor.
A kind of embodiment preferably of this technical solution is that the needle-type film punching machine control system of this structure, can either protect the aperture of mulch film being got hole and meet the requirements, be evenly distributed, and can ensure that again perforating efficiency is high.

Detailed description of the invention
Provide embodiments of the invention below in conjunction with accompanying drawing, be used for further illustrating technical solution.
Found out by Fig. 1, needle-type film punching machine control system arranges module, speed measurement module, control signal module, felt roll control module, porcupine roller frequency transformer control module and winding up roller frequency transformer control module etc. by control module, speed and forms.
Needle-type film punching machine control system operation principle is: when working beginning, first Negotiation speed arranges the linear velocity of mulch film when module installation punches, and then utilizes control signal module to send and starts punching signal.After puncher control module receives enabling signal, start frequency converter and motor with default frequency.When motor just starts, actual linear velocity does not also have and the linear velocity that sets reaches synchronous.After motor rotates, puncher control module Negotiation speed measurement module collects current linear velocity data, and utilizes current linear velocity data to calculate the current diameter of winding up roller, calculates the output frequency of frequency converter according to winding up roller diameter and porcupine roller diameter.The frequency converter output frequency calculated is transferred to porcupine roller frequency transformer control module and winding up roller frequency transformer control module by puncher control module, and the operating frequency of two frequency converters that upgrade in time.After porcupine roller frequency converter and winding up roller frequency converter operating frequency obtain upgrading, actual linear velocity and arrange linear velocity and reach synchronous, rises felt roll, starts punching.After puncher control module receives stop signal, first fall felt roll, then stop the work of frequency converter and motor.
Fig. 2 is the partial circuit of winding up roller and porcupine roller frequency transformer control module, wherein QF0 is master switch, KM1 and KM2 is respectively the contactor in winding up roller motor and porcupine roller electromotor control circuit, MI1 and DCM is frequency converter on off control outside terminal, and switch is therebetween outputed signal by PLC and controls.When master switch QF0 closes, winding up roller frequency converter, porcupine roller frequency converter and PLC are all energized operation, and the original frequency of two frequency converters is arranged by external communication, and start and stop are controlled by frequency converter outside terminal.After PLC powers on, can a default frequency be transmitted first to two frequency converters.When needs actuating motor, one to be inputted to PLC and start control signal, after PLC receives and starts control signal, the outside terminal switch of closed corresponding frequency converter, actuating motor.When puncher is in puncturing patterns, PLC compares and measures the mulch film linear velocity that obtains and arranges linear velocity, dynamically trims the operating frequency value of two frequency converters, and by communication, corresponding frequencies value is transferred to corresponding frequency converter according to measurement result.When needs stop motor, a stop control signal to be inputted to PLC, after PLC receives stop control signal, disconnect the outside terminal switch of corresponding frequency converter, stop motor.
Fig. 3 is tachometric survey and the partial circuit arranging module, and wherein Switching Power Supply is the power supply of powering to two speed probes.After master switch QF0 is closed, PLC works on power, two speed probe energisings, when corresponding measured axle rotates, sensor sends PLC to pulse signal, PLC calculates the rotating speed of measured axle according to the quantity of the pulse signal received and corresponding time, then in conjunction with the diameter of measured axle, calculates the linear velocity of mulch film.
Fig. 4 is the partial circuit of felt roll control module.After PLC receives the control signal of felt roll rise, output signal makes switch close, and felt roll rises.
