Quality appraisal of the winder

coiling machine is a piece of equipment used to make coiled products such as hoses and plastic pipes. It realizes precise control of coiled products such as hoses and plastic pipes by adjusting equipment parameters. Rolling machines can be divided into different types according to the type of roll and the products processed.
rolling machine can roll various soft rolls, film materials, cloth, paper and other materials into standard size reels to meet the needs of production, transportation and storage.
In the quality case of the rolling machine, quality appraisal is an indispensable link. Zhongke Testing provides quality appraisal services for rolling machines.

1. Function failure: Observe whether the winding machine cannot work normally, such as being unable to coil or unload goods, unable to lift or lower, etc. If the winder completely loses its function or some of its functions fail, it may mean a malfunction has occurred.

3. Abnormal pressure: Observe whether the working pressure of the rolling machine is abnormal. If the pressure is too high or too low, it may indicate a problem with the hydraulic system, such as a failed pump or valve, a leak, or a blockage.
4. Difficulty in operation: Pay attention to whether the operation of the rolling machine becomes difficult or unsmooth, for example, the resistance of the operating handle or control device increases, or greater force is required during operation. This can be caused by damaged internal parts, problems with the hydraulic cylinder or motor, or hydraulic blockage.
