Abstract
The invention relates to a pressing device for an uncoiling machine. The pressing device comprises a pressing roll. The pressing roll is located on one side of an uncoiling roll of the uncoiling machine and parallel to the uncoiling roll. The pressing roll is fixed to the top end portion of a swing arm. The swing arm is rotationally connected with a shaft of a sliding wheel. The sliding wheel is arranged on a guide rail. The end, perpendicular to the uncoiling roll and away from the uncoiling roll, of the guide rail is fixedly provided with a pressure applying air cylinder and a displacement hydraulic cylinder. The pressure applying air cylinder inclines relative to the guide rail. The outer end of a piston rod of the pressure applying air cylinder is hinged to the upper portion of the swing arm. The outer end of the piston rod of the displacement hydraulic cylinder is fixedly connected with the shaft of the sliding wheel. By the adoption of the scheme, the quality problem caused by the uneven uncoiling speed of an existing uncoiling machine is solved.
Description
Technical field
The present invention relates to the servicing unit of uncoiler, specifically a kind of pressing device of uncoiling machine.
Background technology
Metallic plate is the basic workpiece of a lot of metallic article, and metallic plate is generally coiling rolling adding man-hour, is fixed on the cylinder of uncoiler by volume, and metallic plate is blank processing after evener leveling.The unwinding device that uncoiler is rolled up as sheet material is widely used, and uncoiler generally drives a cylinder placing sheet material volume rotate around the shaft thus realize uncoiling by motor.But problems of the prior art are, for the metal plate coils that some materials are softer, as foil volume, the speed made the test due to uncoiler is difficult to accomplish accurately constant, when velocity variations is obvious, very easily occurs folded volume or situation about stretching, affects crudy.
Summary of the invention
The object of the present invention is to provide a kind of pressing device of uncoiling machine, it can solve the inconsistent quality problems caused of speed that existing uncoiler makes the test.
Technical scheme of the present invention is as follows:
A kind of pressing device of uncoiling machine, it comprises nip rolls, described nip rolls is positioned at the side of the pay-off roll of uncoiler, nip rolls is parallel with pay-off roll, the top ends of nip rolls and a swing arm is fixed, the axle of swing arm and a pulley is rotationally connected, pulley is arranged on a guide rail, guide rail is vertical with pay-off roll and the one end keeping away winding up roller is fixed with exert pressure cylinder and displacement hydraulic cylinder, cylinder opposite rail of exerting pressure tilts, exert pressure the piston rod outer end of cylinder and the upper articulation of swing arm, the piston rod outer end of displacement hydraulic cylinder is fixedly connected with the axle of pulley.
Further, also comprise and control to exert pressure the controller of the pressure of cylinder and the pressure of displacement hydraulic cylinder.
Further, described swing arm is made up of force application rod portion and support bar portion, and swing arm is connected on support bar portion, and force application rod portion and nip rolls are fixed and coaxial with the piston rod of cylinder of exerting pressure, and the lower end in support bar portion and the axle of pulley are rotationally connected.
Further, described nip rolls is rubber rollers.
The hold down gag of this programme adopts nip rolls to exert pressure to the material volume in pay-off roll, and produces certain frictional force, and when pay-off roll rotates quickening, nip rolls can hinder the rotation of pay-off roll to the frictional force of pay-off roll, has certain inhibitory action; When pay-off roll rotation is slowed down, nip rolls can drive the rotation of pay-off roll to the frictional force of pay-off roll, has certain promotion.Material is smooth output under twisting in the effect of nip rolls.For keeping exerting pressure of nip rolls certain, controller can be adopted to control to exert pressure the pressure of cylinder and displacement hydraulic cylinder.The force application rod portion of swing arm is consistent with the pressure of cylinder of exerting pressure to the thrust of nip rolls, the component of reduced force.Nip rolls adopts rubber rollers, not easily damages material volume, and can ensure necessarily large frictional force.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
A kind of pressing device of uncoiling machine as shown in Figure 1, it comprises nip rolls 2, described nip rolls 2 is positioned at the side of the pay-off roll 3 of uncoiler 1, nip rolls 2 is parallel with pay-off roll 3, the top ends of nip rolls 2 and a swing arm 4 is fixed, the axle of swing arm 4 and a pulley 8 is rotationally connected, pulley 8 is arranged on a guide rail 10, guide rail 10 is vertical with pay-off roll 3 and the one end keeping away winding up roller 3 is fixed with exert pressure cylinder 6 and displacement hydraulic cylinder 7, cylinder 6 opposite rail 10 of exerting pressure tilts, to exert pressure the piston rod outer end of cylinder 6 and the upper articulation of swing arm 4, the piston rod outer end of displacement hydraulic cylinder 7 is fixedly connected with the axle of pulley 8.Displacement hydraulic cylinder 7 promotes the pay-off roll 3 of swing arm 4 near uncoiler 1, and cylinder 6 of exerting pressure promotes swing arm 4 again and rotates until contact to pay-off roll 3, and exerts a force to pay-off roll 3.
Controller 9 controls to exert pressure the pressure of cylinder 6 and the pressure of displacement hydraulic cylinder 7, makes the displacement of swing arm 4 and the support force controllable precise to nip rolls 2.
Described swing arm 4 is made up of force application rod portion 41 and support bar portion 42, and swing arm 4 is connected on support bar portion 42, and force application rod portion 41 is fixing and coaxial with the piston rod of cylinder 6 of exerting pressure with nip rolls 2, and the lower end in support bar portion 42 and the axle of pulley 8 are rotationally connected.
Described nip rolls 2 is rubber rollers, not easily damages material volume, and can ensure necessarily large frictional force.
