Description

High vacuum winding film plating powder clutch automatic tension control device

The utility model relates to a kind of vacuum spirally wound filming equipment, particularly a kind of base material Winding Tension Controlling assembly.

In early days, high vacuum spirally wound filming equipment, usually be made up of the direct-current machine of three band speed measuring motors, its retractable winding up roller and plated film home roll are driven by direct-current machine respectively, and adopting winding tension controller is in torque motor manual control mode or the direct-current machine semiautomatic controls mode that tests the speed, fixed ratio change according to variation of retractable coil coil-diameter and plated film home roll rotating speed, regulation and control retractable winding up roller drive-motor rotating speed, this structure is formed complicated, poor-performing influences the quality of plated film.

The dealer is at the deficiency of said structure, the transmission that improves equipment, to adapt to thinner control requirement, between plated film home roll and wind-up roll, if a speed stabilizing driving roll forms four electric motor driving, its Winding Tension Controlling is with the drive-motor gear shift mode, therefore, must be equipped with the bigger motor of power headroom, the electricity consumption of equipment amount is big, for improving single machine yield, must improve winding speed, costs such as its device fabrication, use, maintenance heighten, and this control device volume is bigger, are difficult to adapt to the various production-scale demands in market.But, in power-actuated mechanical adjustable speed drive, along with development of technology, in some fields, ac motor speed control by variable frequency device (as the FR-540 type etc.), with the powder clutch of micro computer (as the LE-40MTB-E type etc.) controller control (as the ZKB-BN type etc.), the application of all succeeding, and tension pick-up (as the LX-TD type etc.) also has suitable good technical basis, the product of these market supplies is for the tension control of improving high vacuum spirally wound filming equipment provides the necessary technology condition.

The purpose of this utility model is that a kind of improved vacuum winding film plating powder clutch automatic tension control device will be provided, and it can improve the reeling quality of coiling base material, can adapt to the demand of various tension characteristic base material large winding diameter High-efficient Production, and can save the energy.

Utility model is achieved in that high vacuum winding film plating powder clutch automatic tension control device, be provided with a magnetic field powder clutch coupling that has a tension controller on the shaft extension of its retractable winding up roller drive-motor, motor drives through powder clutch and connects the retractable winding up roller; Coating material wear around the path in, between retractable winding up roller and home roll, be respectively equipped with the tensioning roller assembly that touches and be connected with lead with the tension controller of powder clutch with coating material.

The tensioning roller assembly is provided with the tonometry roller that directly contacts with coating material, is installed with the tension pick-up that is connected with lead with the tension controller of powder clutch on the tonometry roller.

When the utility model changes in substrate tension, pick up its variable signal by transmitter and be passed to tension controller, use the regulation and control powder clutch, it is loosened or hold receipts tightly, the shaft extension of let off roll, tension force with base material in the automatic control winding process, the linearity of its feature outclass the characteristic of direct-current machine, make the reeling quality of coiling base material reach smooth, evenly, seamless, thereby guarantee good coating quality, simultaneously can select suitable power of motor for use, tension variation needn't be controlled by electric machine speed regulation, makes equipment that bigger base material loaded space can be arranged, increase winding speed, both improved throughput, again can save energy, and make the entire equipment designs simplification, and can adapt to bigger use range, the be beyond one's reach scope of major diameter base material winding work of particularly early stage equipment.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.
