Process:
The foil roll is introduced into the rubber roller of the feeding device via the decoiling machine and then would in the winding former after passing through the edge of the shearing machine and the roller wheel of the burr pressing device. The inter layer insulation coil is erected in the rear of the coiling optical shaft of the Foil Winding Machine and wound in the winding former after sheared by the trimming roll and the shears blade.
Functional feature:
1. The device adopts and electrical servo deflection correction system to achieve manual/automatic adjustment of the foil position more conveniently and reliably.
2. An advanced electrical control technology of constant tension is adopted to control the tension of the foil and the inter layer insulation, with the features such as quantitive, accurate and convenient control of the tension no mechanical friction. The required tension can be maintained for forward winding, stop and backward winding, ensuring compact coils.
3. The inter layer insulation adopts a cantilever mechanism, convenient for feeding and the mechanism can be pulled out as a whole without guide rails outside the body.
4. Automatic welding mechanism and roll shearing mechanism adopt ball screws and linear guide rails for drive, ensuring the service life and accuracy of the device.
5. This device first adopts the all-in-one sing frame, solving problems such as few coil urns and deflection correction lag.
6. This device is a hi-tech product produced by combining with actual production on the basis of many similar products at home and abroad. The whole machine is controlled via an advanced PLC touch screen, with high automation level and simple and reliable operation, representing higher production level of domestic foil winding machines.

Analysis on the Performance, Installation and Maintenance of Metering Pump Back Pressure Valve
Dosing pumps as the ideal chemical injection equipment ideal, widely used in petrochemical, chemical, oil and gas fields, power, paper, pharmaceutical, environmental protection, water treatment and other industries. Dosing pump back pressure valve, there are two general purposes. 1. Used to prevent the gravity flow of gravity under gravity (or siphon), this time generally greater than the pressure of the liquid itself can be used, such as to prevent the liquid level of 2 meters medicine tank gravity, the pressure can be greater than 0.02MPa back pressure Valve, the general metering pump can be used 0.1MPa. 2. Used to stabilize the metering pump flow, such as some metering pump flow with the pressure changes larger, can be set in the metering pump outlet back pressure valve, the metering pump output flow stability, then generally choose back pressure valve The pressure for the metering pump actual use pressure or slightly less than the metering pump working pressure. The check valve in the outlet pipe is used to prevent backflow of the liquid and the back pressure valve is used to maintain a constant pressure at the metering pump outlet. Due to the reciprocating movement of the metering pump, the driving part has a certain impact sound is normal phenomenon, GB / T7782-1996 "metering pump" provisions in the distance of 1 meter from the pump is not the noise of 75 dB (of course, the smaller the better), abnormal sound , The following may be caused by the following reasons: a. The pressure of the pump exceeds the rated pressure of the pump (This phenomenon may occur when the check valve on the pipe is not clear. You can install a pressure gauge at the outlet of the metering pump to the check valve to check the outlet pressure of the metering pump ). b. Worm bearing damage.
