Description

Technical Field

[0001] The utility model relates to the technical field of rack chain overload prevention devices, in particular to a mechanical overload prevention device for a rack chain of a clothing assembly line. Background Art

[0002] The clothing assembly line is a production method that makes clothing production more efficient and systematic by breaking down the production process into a series of small steps. The rack chain overload protection device in the clothing assembly line can prevent overload or abnormal load from damaging the equipment, reduce the risk of equipment failure or accidents, and thus protect the safety of operators. By effectively preventing overload, the rack chain overload protection device can ensure the continuous and stable operation of the production line, avoid downtime caused by equipment failure or damage, thereby improving overall production efficiency and extending the service life of the equipment.

[0003] The existing rack chain achieves overload protection by controlling the driving motor current. Another method is to add an encoder to the rack chain and judge the overload of the rack chain according to the speed difference of the rack chain. However, the effect of neither the motor current nor the encoder is good. The motor control range is wide and the error is relatively large. The encoder control distance is limited and cannot protect the entire chain. Therefore, the mechanical overload protection device of the rack chain needs to be improved. Utility Model Content

[0004] One purpose of the present invention is to propose a mechanical overload protection device for a rack chain of a clothing assembly line. When the rack chain of the present invention is overloaded, it will drive the motor to rotate, and the rotation of the motor will drive the platform plate to rotate. The rotation of the platform plate will touch the micro switch, thereby triggering the micro switch and transmitting the signal to the controller and the circuit board. The power supply of the motor is turned off by the controller, and the circuit board has a self-locking function. After the power is cut off, the motor cannot be restarted even if it is reset. It needs to be manually reset after personnel inspection. The overload protection force generated by the rack chain is driven by the rotation of the platform plate to drive the fixed rod to rotate along with the movable block at the bottom, which can drive the springs on both sides to perform elastic deformation, thereby alleviating the generated overload force, and can ensure that the overload force is in an adjustable state, and the control is more precise; after the overload protection is triggered, it plays a self-locking role, and can only be restarted after personnel inspection and reset, to prevent personnel from operating incorrectly.
