Preparation of slitter cutter
1. Razor slitting
1.1. The razor slitting requires the film to travel in the correct direction to the winding section.
1.2. Adjust the photoelectric tracking to bring the film to the proper position.
1.3. Tension the film and attach the blade to the razor holder.
1.4. According to the specifications required by the instruction sheet, the sliding razor holder is cut into the razor groove under the film, and the blade edge and the edge of the sipe are required to be in contact with each other.
1.5 After adjusting the depth of the cutter, lock the razor frame screws.
2. Round knife cutting
2.1. Check whether the upper and lower knives are sharp and have no gaps, and vice versa;
2.2. Determine the number of knives (N+1) according to the number of product series (N);
2.3. Install the lower knife to adjust the width of the lower knife according to the actual width of the product;
2.4 Install the upper knife correctly. The flat side of the upper knife is aligned with the side of the lower cutting edge. The upper knife is aligned with the gap between the lower knife and the septum. Press the screws on both sides to make the upper knife enter the gap depth to about 2mm. The upper knife is attached to the lower knife and fastened. Finally, the screw on the left side of the upper knife holder is adjusted so that the whole knife holder moves 1-2 mm to the right side and is fastened.

six. Burr

The raw edge product not only affects the appearance, but also directly affects the use. The edging product is observed with a magnifying glass. The edge of the film is jagged. The film roll is prone to breakage during use, and the consequences are very serious. For example, if the printed film breaks during the printing process, the ink will be caused. Splash, need to clean the machine and the ground, and then lead the film, re-coloring and other processes, production of physical and working loss; if the tape film breaks during the coating process, it is necessary to open the oven more than ten meters, re-introduction Membrane, turn off the oven, heat up and reproduce. These are things that users are very annoying and we must pay attention to.

In addition, we must pay attention to the protection of the end face during the moving process of the film roll, the film end face gap caused by the operation accident, and the gap has high concealment, the problem is difficult to find and flow to the user, the product will be Use has a greater impact.

ten. Color circle

The factors that cause the film to roll the color circle are:
(1) Contamination equipment is contaminated: due to the pollution of the dust in the cutting workshop, as well as the operation of the equipment in the slitting process and the friction between the membrane and the friction generated by the static electricity, the cutting equipment continuously accumulates more and more dust. When it accumulates to a certain extent and fails to clean in time, it will pollute the slit film roll to form a color circle. In addition, the aging and hardening of the roll skin (sand) debris will also cause the color circle of the film roll to appear.
(2) The environment of the cutting environment is polluted: during the cutting process, due to the influence of some accidental pollution sources, such as the dust on the ceiling of the cutting machine, the exhaust of the diesel forklift, etc., the air is spread to pollute the cutting products. And form a color circle.
In order to effectively reduce the impact of color circles on product quality, the following measures must be taken:
(1) Do 5S work regularly to maintain the sanitation of the workshop and the cleanliness of the machine; (2) It is forbidden to open the doors and windows without sand filter for a long time, and keep the good habit of closing the door;
(3) The contaminated film on the surface of the parent roll must be removed before the film can be cut, so as to avoid the dirt of the surface film from contaminating the cutting machine;
(4) The diesel forklift that requires black smoke is kept away from the surrounding of the workshop to prevent the tail gas pollution from being cut into the products.
