[0001] The utility model belongs to the field of film production equipment, in particular to an adjustable slitting device. Background Art
[0002] With the advancement of science and technology, there are more and more types of films, their performance is getting better and better, and their production costs are getting lower and lower. Films are used in more and more places in industrial production and people's daily lives, so higher and higher requirements are put forward for the production efficiency of films and the quality of film rolls. Before use, the film often needs to be slit to meet the width requirements of use. In order to meet the different slitting width requirements of different products, it is often necessary to adjust the distance between the slitting knives of the slitting machine during the slitting process of the film. The position adjustment between the slitting knives on the existing slitting machines is usually manually adjusted, which is time-consuming and labor-intensive, heavily dependent on experience, and the accuracy is still difficult to be very precise, which affects the production speed and the quality of the film roll.
