Roll feeding device for printing film production

Abstract

The invention discloses a roll conveying device for producing a printed film. The roll conveying device comprises film winding rolls, a control device, a fixer, a locking shaft, a movable shaft capable of actively moving up and down and a fixed shaft, wherein the fixer, the locking shaft, the movable shaft and the fixed shaft are sequentially arranged; two parallel fixing plates are vertically mounted on the fixer; the fixing plates are fixed to the fixer through first mounting shafts capable of actively rotating; two telescopic second mounting shafts capable of actively rotating are arranged on each fixing plate; the upper and lower two film winding rolls are mounted between the two fixing plates; each film winding roll consists of a central shaft, side baffles and a protective barrel; the two ends of the central shaft are separately connected with the second mounting shafts located on different fixing plates; the two side baffles are mounted on the central shaft; the side baffles are connected with the central shaft through a main bearing; and the main bearing is embedded in the central shaft. By mounting the two film winding rolls on the rotatable fixing plates and matching the locking shaft, the film winding rolls can be conveniently changed. When the film winding rolls are changed, normal production also can be carried out.

Problems solved by technology

[0002] In the production process of gusset plate, printing film will be used. The printing film needs to use roll feeding device in the production process. The existing roll feeding device needs to stop printing when replacing the new film roll, which is not conducive to the improvement of production efficiency. , at the same time, the weight of the loaded film roll is relatively heavy, and the installation process is more troublesome

The blank film on the film roll on the roll feeding device is in direct contact with the external environment. If the blank film is stored for a long time, it is easy to be polluted and easily worn, which will affect the quality of the product.

Moreover, the existing film roll needs the operator to judge with the naked eye when judging whether the blank film is used up, which is not conducive to the effective use of the blank film.
