Abstract
The utility model discloses a kind of mill roll state homalocephalus detent mechanism, milling train comprises rolling mill body, roll, connecting rod and homalocephalus, and drive the motor of roller rotational, described connecting rod end is provided with projection, described rolling mill body is provided with proximity switch, when described connecting rod is transported to correct position, described bump contact proximity switch, described proximity switch is that output control circuit is normally closed switch and is connected on the power supply circuits of motor.The utility model mill roll state homalocephalus detent mechanism structure is simple, and equipment investment cost is few, safe and reliable, improves the efficiency and security of changing roll.
Description
Technical field
The utility model relates to milling train field, particularly relates to the mechanism of a kind of supplementary mill roll change state homalocephalus location.
Background technology
Before milling train more renews roll, need homalocephalus to navigate to specific position so that the installation of new roll.Because the position of connecting rod is at the rear of operating desk and memorial archway, location needs an operative employee rotate roll on operating desk, and another operative employee goes to rear to see position, just can complete location, therefore there is following problem: 1, a people is difficult to complete operation; 2, naked eyes judge position, cannot accomplish accurate location; 3, under equipment running status, at equipment rear, observation has certain potential safety hazard.
Utility model content
Technical problem to be solved in the utility model realizes the mechanism that a kind of raising more renews roll efficiency and security.
To achieve these goals, the technical solution adopted in the utility model is: a kind of mill roll state homalocephalus detent mechanism, milling train comprises rolling mill body, roll, connecting rod and homalocephalus, and drive the motor of roller rotational, described connecting rod end is provided with projection, and described rolling mill body is provided with proximity switch, when described connecting rod is transported to correct position, described bump contact proximity switch, described proximity switch is that output control circuit is normally closed switch and is connected on the power supply circuits of motor.
The utility model mill roll state homalocephalus detent mechanism structure is simple, and equipment investment cost is few, safe and reliable, improves the efficiency and security of changing roll.
Accompanying drawing explanation
Below to the content brief description that width accompanying drawing every in the utility model description is expressed:
Fig. 1 is detent mechanism circuit theory schematic diagram.
Detailed description of the invention
Milling train comprises rolling mill body, roll, connecting rod and homalocephalus, before milling train more renews roll, need homalocephalus to navigate to specific position so that the installation of new roll, roll is connected with connecting rod, roll and connecting rod are driven by motor and operate, milling train connecting rod end (root) welds a projection, rolling mill body is fixed a proximity switch, the position of proximity switch is when connecting rod is transported to correct position (setting needs the position stopped), projection on connecting rod just in time contacts with proximity switch, then can automatically control running by proximity switch, when running to correct position, autostop, two staff do not coordinate observation.
As shown in Figure 1, proximity switch is that output control circuit is normally closed switch and is connected on the power supply circuits of motor, motor controlled by PLC and proximity switch output status signal to PLC.Before changing roll, after manual adjustment homalocephalus to the position needed, stop roll rotation, the break-make effect of recycling proximity switch, realize the automatic rotation location of roll, need add the condition of roll change state during setting program before proximity switch, proximity switch introjection when preventing from normally running, causes unit exception to stop.After changing roll, excision proximity switch and projection, equipment then can normally work.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
