Description
Technical field
This utility model relates to a kind of arrangements for speed regulation, especially relates to the synchronous speed regulation device of a kind of disc paper cutting rewinding machine.
Background technology
Disc paper cutting rewinding machine is used for producing health toilet paper shallow bid paper, perfect along with public place facility, it is widely used in hotel, the toilet of the public places such as office building, the accreditation of little obbbin is day by day increased by people with demand, and modern little obbbin not only requires to want health clean, and for the shape of paper, thickness all requires, and requires that the paper product outward appearance produced wants clean and tidy, trimming edge can not be unedged simultaneously.
Existing disc paper cutting rewinding machine operating process:
Machine (Pneumatic charging) pneumatic feed on raw material---manual type tension adjusting device embossing void is cut (punching) cutting and rewinding and is released finished product
Existing equipment feature:
The least obbbin paper tube core uses air-expanding shaft location, rolling.
2. mechanical type paper loading rack paper feeding, pneumatic type width belt paper feeding.
The most each paper loading rack all has independent tension adjusting apparatus.
4. tension adjusting device uses manual type V belt buncher.
Manual type V belt buncher structure is as in figure 2 it is shown, speed control principle: it is to realize the change of diameter pulley by two driving wheels of opening and closing, to reach the purpose of speed governing.During speed governing, because fixed wheel is motionless but move the driving wheel on both sides, so the spacing of two root bark bands produces change the most accordingly.
There is following defect in existing speed control device:
1) due to tension adjusting device be use manual type V belt buncher speed governing, lack adjust promptness.
2) whether what tension force controlled stablizes the quality being directly connected to product:
If tension force is not enough, body paper is in operation and produces drift, it may appear that finished paper wrinkling after cutting and rewinding；If overtension, body paper is the most easily pulled off, and after making product rewinding, finished paper broken end increases.
3) use machine driving due to tension adjusting device, so the coaxial transmission serious wear of machinery, need often maintenance.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and the synchronous speed regulation device of a kind of disc paper cutting rewinding machine is provided.
The purpose of this utility model can be achieved through the following technical solutions:
The synchronous speed regulation device of a kind of disc paper cutting rewinding machine, in order to keep big volume and the equalization of strain of rouleau in disc paper cutting rewinding machine, including PLC, big volume adjusting part and rouleau adjusting part, described PLC is connected with big volume adjusting part and rouleau adjusting part respectively；
When being adjusted, big volume adjusting part and rouleau adjusting part connect the torque and rotating speed obtained respectively on big volume motor and rouleau motor, PLC adjusts big volume motor and the rotating speed of rouleau motor and torque according to the torque on big volume motor and rouleau motor and rotating speed closed loop respectively, thus keeps big volume and the equalization of strain of rouleau in disc paper cutting rewinding machine.
Described big volume adjusting part includes the primary transducer being sequentially connected with, big volume motor and main encoder, and described main encoder is connected with PLC.
Described rouleau adjusting part is provided with multiple, and quantity is consistent with rouleau quantity, including be sequentially connected with from converter, rouleau motor and from encoder, described is connected with PLC from converter.
Described main encoder and all include torque harvester from encoder, in order to gather big volume motor and the output torque of rouleau motor respectively.
This device also includes the touch screen being connected with PLC, in order to show torque, rotating speed and coil diameter and to set tension force preset value.
Described main encoder and all include coil diameter harvester and rotating speed harvester from encoder.
Compared with prior art, this utility model has the advantage that
1) harsh environments can be fitted, possess that capacity of resisting disturbance is strong, reliability is high, length in service life, precision high.
2) tension force is set in man-machine upper setting, the operating system of hommization.
3) overcome the machinery rolling drawback to mechanical wear, in the service life of prolonged mechanical, maintain easily equipment.
4) data are through PLC process, at specific dynamic process, and energy dressing parameter in time so that the performance of rolling is more preferable.
5) owing to using Frequency Converter Control, make main frame speed and put chart speed degree and obtain synchronize, rolling whole during can keep constant tension force.
(1) when starting rouleau, it is impossible to the disconnected paper because of overtension；Can not pine paper during big volume initialization.
(2) when accelerating, slow down, above-mentioned situation can not be had to occur when stopping.
6) touch screen is used can not only to carry out dynamic data modification, moreover it is possible to tension force is quantified display.
7) mechanical governing is relatively slow to velocity variations reaction, introduces the problem that electron controls technology improves this respect.
8) electron controls technology is used to improve the problem that the low torque conversion range of mechanical transmission efficiency is limited.

Fig. 2 is the structural scheme of mechanism of prior art.
Wherein, 1, PLC, 2, primary transducer, 3, roll up motor greatly, 4, main encoder, 5, from converter, 6, rouleau motor, 7, from encoder, 8, touch screen.
Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment:
1) primary transducer be complete machine power drive, 1# from converter be 1# paper loading rack paper feeding power, 2# be 2# paper loading rack paper feeding power from converter, touch screen is used for data feedback for parameters revision, PLC for system control, encoder, it is configured so that and makes equipment electrical control be in a complete closed loop system, thus fully eliminate overtension and cross minor issue.
2) job requirement:
Tension force controls to refer to control enduringly the ability of tension force when body paper carries on equipment.This control all must keep effective to any speed of service of machine, including the acceleration of machine, deceleration and at the uniform velocity.Even if in the case of stopping in emergency, also should have the ability to ensure that slitting thing is the most damaged.Use master & slave control method just can reach tension force and control purpose.
Technical basis:
The essence making constant tensile control of converter is the closed-loop vector utilizing converter to be controlled, additional encoder feedback.For folding and unfolding paper roll, the coil diameter of rolling is ascending change, in order to ensure identical tension, it requires that the output torque of motor wants ascending change.Simultaneously in different operating process, corresponding torque compensation to be carried out.Moment of the least volume initialization, accelerating, slow down, stop, during big volume initialization, will carry out different torques when different coil diameter and compensate, the whole process that thus can make rolling is the most stable, it is to avoid overtension during rouleau；The phenomenon of pine yarn during big volume initialization.
