Feature of the present invention is: first by the opening degree of lift adjusting upper roll, make opening degree reach the suitable dimension of materials demand; Then realize the Quick-clamped of roller by upper and lower hydraulic cylinder and unclamp, and driving down roller to realize sending to of workpiece by motor.
Accompanying drawing explanation
Below in conjunction with embodiment, the present invention is further illustrated;
Fig. 1 is the structural representation of pinch roll mechanism.
In figure: 1, frame; 2, upper pendulum bar; 3, top roll transmission device; 4, lower roll transmission device; 5, draft link; 6, lower hydraulic cylinder; 7, upper hydraulic cylinder; 8, lift.
Specific embodiment
As shown in Figure 1, lower hydraulic cylinder 6 and lift 8 are arranged on two side bottoms of frame 1 respectively, lower hydraulic cylinder 6 by cylinder bottom and frame 1 hinged, lift 8 and frame 1 are slidably connected.
Draft link 5 is L-shaped, and its one end is by bearing pin and frame lower pin joint, and draft link can rotate around this fixing point; Right angle and the lower hydraulic cylinder 6 of draft link 5 are hinged, and the other end of draft link 5 is fixedly connected with lower roll transmission device 4.
Upper pendulum bar 2 is also L shape, and on it, edge lengths is greater than the width of frame 1, and the long limit of upper pendulum bar 2 is by the top pin joint of bearing pin and frame 1, and upper pendulum bar 2 can rotate around this fixing point; Upper pendulum bar 2 one end is fixedly connected with top roll transmission device 3, the other end and upper hydraulic cylinder 7 hinged, the cylinder bottom of upper hydraulic fluid cylinder 7 is fixedly connected with lift.
The axis of top roll transmission device 3 and upper and lower two rollers in lower roll transmission device 4, and can do suitable adjustment by upper and lower hydraulic cylinder point-blank.
Upper hydraulic cylinder and lift in the same side of frame, top roll transmission device, lower roll transmission device and lower hydraulic cylinder at the opposite side of frame, by the flexible rotation achieving upper and lower roller drive of upper and lower fluid cylinder.
Upper and lower roll transmission device drives upper and lower roller to realize sending to of workpiece by motor.
During work, first according to the size of workpiece, adjusted the opening degree of top roll by lift 8, under the driving of motor, workpiece is sent into, and realizes the clamping of roller simultaneously and unclamp by upper and lower hydraulic cylinder.
The parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.
