What is decoiler? Decoiler is power driven equipment mainly according to the need of the printing unit feed quantity (paper pull reel paper rotational speed) to adjust the supply of paper. To control the rotational speed of drum paper process is implemented by clutch and scrolls. Before adopting the electromagnetic clutch, C and Z purlin machine adopts pneumatic clutch. In the process of printing, the printing speed is not a constant value, which is gradually increasing. Sometimes decoiler needs to use the tension roller to control the supply of paper and tension.

What is decoiler? Around anchors, tension roller cylinder decoiler and paper tension balance will ensure the tension roller in a state of balance. Tension roll position which indicates that the tension of paper and the size of the paper supply will put the location of the input for the tension and speed of paper supplies. In the printing process, the tension roller floating up and down the smaller the distance. The more conducive stability of paper tension is decoiler. Tension controller is a key component in uncoiling machine tension control system. It is mainly to complete the detection signal processing, analysis and execute the command. At present our country mainly adopts controller. This controller can indicate and clutch paper scrolls the working state of the brake pads, but the decoiler can set at any time or the position of correct tension roller.

What is decoiler? According to the requirements of the frontier printing press, the decoiler will generally use web to order. Due to different C purlin machine types, decoiler paper core shaft diameter difference is more. Normally when we order rolls of paper, first of all we will consider the paper roll core shaft diameter size. General requirements of roll paper core diameter is larger than the paper core shaft 2 to 5mm. Decoiler should be paid attention to second, which can also use the largest outside diameter with the installation. The decoiler should check whether there is any deformation on paper core. If deformation is too big, it should be repaired. After they straighten out core insert paper rolls of purlin forming machine, then they will check that the paper at the ends of the spindle distance, which try to install the web center.

What is decoiler? The decoiler after the computer can make sure horizontal in the same location as the roll of paper. It will use double-sided and single-sided adhesive tape paper paste. In the process of stitching, the decoiler can ensure that the two roll diameter which is consistent with linear velocity. If the paper is manual decoiler, it will roll-up drum paper cut, after the adjustment of paper transverse position, directly at the beginning of the new roll of paper. On the top of the coil, the purlin line needs to have at least roll motor. It is better to hydraulic motor and hydraulic motor speed.
