Description
Technical field
The utility model relates to the electric field that drags of Cereals Processing Machines hulling machine, and is a kind of especially by adopting the mode of variable frequency adjustment roll rotational speed, traditional hulling machine electric part put together the device of control.
Background technology
The hulling machine roller motor needs to regulate the roll relative velocity when work, and traditional handicraft is to utilize gear box to carry out speed change, reaches the purpose of the relative velocity that changes roller motor.As shown in Figure 1, in order to reach the purpose that changes the roll relative velocity, original hulling machine has adopted speed-changing gear box, by changing the gear ratio of speed-changing gear box, regulate speed change roll 2 speed.
The course of work is as follows: before working on power, regulate the rotating ratio of hulling machine speed change roll 2 earlier by speed-changing gear box, power on then, constant speed motor directly connects the AC220V electrical network, so the rotating speed of constant speed roll 1 keeps constant in the course of the work always; Speed change roll 2 drives by a speed-changing gear box cause another one constant speed motor, by the gear graduation ratio that has mixed up, changes the rotating speed of speed change roll 2, the purpose that provides relative rotation speed to realize hulling paddy.This kind scheme is generally to adopt at present, and its inconvenience mainly is exactly, and troublesome poeration needs to shut down and readjust the direct relative rotation speed of roll, and operating efficiency is lower.
The utility model content
The purpose of this utility model provides a kind of variable-speed gear system, high efficiency, function admirable, reliability height and hulling machine roll speed governing central control device easy to maintenance of replacing.
For solving the problems of the technologies described above, the utility model is realized as follows: a kind of hulling machine variable frequency adjustment roll rotational speed central control device comprises frequency converter, contactor and control end; Frequency converter is connected with control end, constant speed motor is connected with frequency converter by contactor, and variable speed electric motors, particularly is connected with frequency converter, and constant speed motor is connected with two interactional constant speed rolls respectively with variable speed electric motors, particularly.
Good effect of the present utility model is: the special converter that the utility model adopts independent development not only can be reliably, stable operation; Secondly can save energy and reduce the cost and the recovery of investment in technological upgrading; Avoid changing original motor again as much as possible, reduce the change of system.At last, RHVC is installed on the existing system as far as possible, avoids increasing cabinet.The utility model has improved technical process, improves control performance, replaces speed-changing gear box, prolongs the useful life of equipment.

Fig. 3 is the schematic diagram of the utility model variable frequency adjustment roll rotational speed central control device.
Embodiment
The groundwork principle of hulling machine is utilize to change relative velocity between two rolls to realize that paddy sloughs clever shell, makes the purpose of brown rice.
A kind of hulling machine variable frequency adjustment roll rotational speed central control device comprises special converter, contactor, control end.Special converter replaces original variable-speed gear system; Contactor is to make things convenient for centralized control used, controlled to the constant speed roller motor by special converter in implementation civil power is provided, and keeps the constant speed running; Control end is the human-machine operation transposition of whole hulling machine, running that can the centralized control hulling machine with stop, changing the high low speed of roller motor, rotating etc.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, the utility model has replaced speed-changing gear box with a special converter, and special converter is used for controlling motor, electric-machine directly-driven speed change roll.
Workflow is as follows: system has two motors and drives constant speed roll 1 and speed change roll 2 respectively, connect AC220V voltage during work, do not need to regulate in advance the rotating speed of speed change roll 2, get final product the rotating speed of real-time adjusting speed change roll 2 in the course of the work by special converter, thereby change constant speed roll 1 and speed change roll 2 direct relative velocities.The control of special converter makes that the adjusting rotating speed is convenient and reliable, carries out in real time, has improved operating efficiency greatly.
As shown in Figure 3, first execution mode of a kind of hulling machine variable frequency adjustment roll rotational speed central control device described in the utility model is: special converter is connected with control end, constant speed motor is connected with frequency converter by contactor, variable speed electric motors, particularly is connected with frequency converter, and constant speed motor is connected with speed change roll 2 with two interactional constant speed rolls 1 respectively with variable speed electric motors, particularly.X1 is the switching value signal, starting command; X2 is the switching value signal, halt command; X3 is the switching value signal, the rotating order; X4 is the switching value signal, high low speed order; X5, X6 are the switching value signal, reserve; AI1 is analog signals, and 4～20mA reserves;
Workflow is: connect the AC220V power supply, adopt the given mode of terminal, arrange variable speed electric motors, particularly rotating, high low speed, be set rotating switching time etc., press the X1 starting switch, behind about 2s, constant speed motor major loop contactor closure, constant speed motor is started working, and variable speed electric motors, particularly also begins to turn to (forward or reverse) work according to the rotating speed of setting (high speed or low speed) simultaneously, after starting is finished, enter steady operation.The course of work can change turning to of rotating speed of motor, motor by the mode that the terminal switch is set at any time, and fast and stable is reliable.Only need press the X2 halt switch if need to shut down then, then variable speed electric motors, particularly and constant speed motor can shut down.
Be installed together centralized control by hulling machine special converter, control end and contactor with independent development, Optimal Structure Designing, take into full account dustproof heat radiation, security requirement, take loop of power circuit and control loop separately, so external dust can not accumulate on the control loop, avoid influencing the frequency converter function.The radiator in transducer power loop also is designed to make things convenient for the structure of dedusting simultaneously, is convenient to artificial dedusting regularly.
Therefore, the utility model has been realized not shutting down speed governing in the hulling machine course of work, and velocity-stabilization is reliable, has improved the operating efficiency of hulling machine greatly.
Realization of the present utility model is described for example, has described above-mentioned embodiment.But other variations of the present utility model and modification; be apparent for those skilled in the art, any modification/variation in essence disclosed in the utility model and basic principle scope or imitation conversion all belong to claim protection range of the present utility model.
