2, when belt reversing, custom operation or misoperation appear in operative employee regular meeting, because in the motor positive and inverse circuit, stop button SB1 is in normally off, is just playing button SB2 and are being in normally open with the anti-button SB3 of rising; When starting when just playing button SB2, positive contactor coil KM1 gets electric, and positive contactor coil is often opened subsidy contact KM1 adhesive, and the simultaneously positive contactor coil normally closed subsidy contact KM1 that interlocks disconnects, and motor just changes.If in just changeing, play counter-rotating, closed SB3, anti-clinching normally closed contact SB3 disconnection this moment, positive contactor coil KM1 outage, KM1 disconnects thereby positive contactor coil is often opened the subsidy contact, and the positive contactor coil normally closed subsidy contact KM1 closure of interlocking makes positive crossover outage; While is electric owing to counter-rotating contactor coil KM2 gets, and the counter-rotating contactor coil is often opened subsidy contact KM2 closure, and motor is without direct stressed counter-rotating of deceleration.Motor just changes and earlier belt is not stopped in (or counter-rotating) process and directly play counter-rotating (or just changeing), not only lacked the step of adjusting belt, make belt deviation easily, and in this process, the belt forced brake also immediately oppositely quickens to make current of electric strengthen, easily burn motor, and motor shaft oppositely is subjected to strong reversing suddenly, moment of torsion moment increase very easily causes shaft break of motor;
No matter be that belt deviation or motor shaft twist off, all will cause unnecessary loss:
In case belt deviation just will aggravate the wearing and tearing of belt, the belt life cycle is shortened; It is serious to cause belt to spill material simultaneously, and the increasing of material that land easily causes mixed matter, and product quality is reduced; Removing is landed and is expected to have strengthened operating personnel's workload and labour intensity, has consumed great amount of manpower and time.And if shaft break of motor, constitution equipment accident not only then, and loss is also even more serious.Owing to often change belt, motor or motor shaft, both increased attendant's labour intensity, strengthened expense and cost; Also reduced the operating rate of equipment simultaneously, untimelyly also will directly influence production, resulted in greater loss if change.
Summary of the invention
The purpose of this utility model is exactly at the problems referred to above, aim to provide a kind of by postponing belt motor rotating start-up time, thereby reduce Motor torque, prevent the startup protective circuit design of belt deviation.
For this reason, the technical solution taked of the utility model is:
A kind of belt motor start delay circuit, comprise counter-rotating contactor coil interlock normally closed subsidy contact KM2, counter the interlock normally closed subsidy contact KM1 and just playing clinching normally closed contact SB2 of clinching normally closed contact SB3, positive contactor coil that rises, it is characterized in that, in positive crossover and counter-rotating circuit respectively and meet time relay KT1 and KT2; The time relay retarded closing contact KT1 that promptly between the counter-rotating contactor coil of positive crossover is interlocked normally closed subsidy contact KM2 and the anti-clinching normally closed contact SB3 of rising, connects, the positive contactor coil of the circuit that reverses interlock normally closed subsidy contact KM1 with just play the time relay retarded closing contact KT2 that also connects between the clinching normally closed contact SB2.
The beneficial effects of the utility model are:
Adopt the belt motor start delay circuit of the utility model, the motor that can effectively prevent to cause because of misoperation or custom operation has reduced motor shaft and has twisted off accident without the oppositely stressed problem of slowing down directly, has improved motor useful life; Control the belt deviation phenomenon, alleviated the belt wearing and tearing, prolonged the belt life cycle; Reduce belt and spilt material, avoided mixing matter, reduced workload and labour intensity that cleaning is spilt material, changed belt and motor, saved the cost expenditure, guaranteed the direct motion of producing.;
