Abstract
The utility model provides a scour protection top controlling means, ascending including drive paper feeding elevating platform or descend motor to reach the electric machine control major loop, and be equipped with the normally open contact of master control contactor on this electric machine control major loop, its characterized in that still is equipped with the normally open contact of protection contactor on the electric machine control major loop, and the protection contactor coil set up in taking limit switch's protection circuit. Make the paper feeding elevating platform rise to anomalous position and when touching limit switch, can break off the protection circuit immediately, make the motor stall, prevent to rush to summit. The utility model has the advantages of simple structure and reliable performance, prevent effectively that the paper feeding elevating platform from rushing to summit, protected the safe operation of equipment and motor, guarantee production normal clear.
Description
Technical field
This utility model relates to a kind of device that controls, and especially a kind of controls the device that printing die ironing equipment paper feeding lifting platform is rushed to summit, and belongs to printing equipment and controls technical field.
Background technology
Printing die ironing equipment in process of production, owing to paper feeding lifting platform frequently rises, usually can cause electrical control gear to break down, and causes paper feeding lifting platform out of control and damages or cause electrical fault, namely usually said rushes to summit.Phenomenon of rushing to summit all occurred in many equipment, and fault rate is higher, and not only impact produces and increases maintenance cost, also even with the life-span, the precision of equipment and debugging is brought considerable influence.Fault of rushing to summit is bigger and frequent break-make mainly due to major loop ascending current, it is easy to makes ac contactor contact produce spark and makes contact surface fusing and bonding, after causing coil losing electricity also cannot break contact, stop electric machine rotation.Therefore, it is necessary to prior art is improved, to prevent the accident of rushing to summit.
Summary of the invention
The purpose of this utility model is in that to provide a kind of preventing colliding with top to control device, in order to effective control paper feeding lifting platform is out of control and damages or washes out motor.
This utility model is completed by following technical proposal: a kind of preventing colliding with top controls device, including the motor driving paper feeding lifting platform to rise or fall, and motor controls major loop, and the normally opened contact of master control catalyst is controlled major loop is provided with at this motor, it is characterized in that controlling major loop is additionally provided with the normally opened contact of protection catalyst at motor, protection contactor coil is arranged on in the protection circuit of limit switch, so that when paper feeding lifting platform rises to out-of-the way position and touches limit switch, disconnect protection circuit, make the protection contactor coil dead electricity in protection circuit, the normally opened contact making protection catalyst disconnects, and leave the motor off rotation, prevent from rushing to summit.
Described protection circuit is connected with power supply.
Described limit switch is matched with the preventing colliding with top collision block being arranged on paper feeding lifting platform or touching lever, in order to when paper feeding lifting platform rises above precalculated position, is backed down limit switch by preventing colliding with top collision block or touching lever and is disconnected protection circuit.
This utility model has following advantages and effect: adopt such scheme; can conveniently by being arranged on the normally opened contact protecting catalyst that motor controls on major loop; and it is arranged on the protection contactor coil in the protection circuit of limit switch; when making paper feeding lifting platform rise to out-of-the way position and touch limit switch; protection circuit can be disconnected immediately; and leave the motor off rotation; prevent from rushing to summit; this utility model simple in construction, dependable performance; effectively prevent paper feeding lifting platform from rushing to summit; protect the safe operation of equipment and motor, ensure that production is normally carried out.
Accompanying drawing explanation
Fig. 1 is this utility model circuit structure diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
Such as Fig. 1; the preventing colliding with top that this utility model provides controls device and includes: drive the motor M that paper feeding lifting platform rises or falls; and conventional motor controls major loop Z; and the normally opened contact KM-1 of master control catalyst is controlled major loop Z is provided with at this motor; control to be additionally provided with on major loop Z the normally opened contact KM0-1 of protection catalyst at motor, protection contactor coil KMO is arranged on in the protection circuit B of limit switch SQO；Described protection circuit B is connected with power supply.
During normal operation, motor controls major loop Z, the normally opened contact KM-1 of master control catalyst, the normally opened contact KM0-1 of protection catalyst, protection circuit B normal operation；When paper feeding lifting platform rises to out-of-the way position; when backing down limit switch SQO by the preventing colliding with top collision block being arranged on paper feeding lifting platform; namely protection circuit B is disconnected; make the protection contactor coil KMO dead electricity in protection circuit B; the normally opened contact KMO-1 then protecting catalyst disconnects; cut off motor to control major loop Z and make motor M stop operating, it is prevented that rush to summit；Even if the normally opened contact KM-1 that motor controls the master control catalyst in major loop Z occurs abnormal; contact surface fusing is made and bonding as produced spark; when also cannot disconnect the normally opened contact KM-1 of master control catalyst after causing the coil losing electricity of master control catalyst; also by protection circuit B; make the protection contactor coil KMO dead electricity in protection circuit B; so that the normally opened contact KMO-1 that motor controls the protection catalyst in major loop Z disconnects; motor M can be allowed to quit work, effectively protect the equipment such as paper feeding lifting platform and motor M to be not damaged by.
