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.

Slitting machine operating procedures -

Third, through the film:

14. Press the “MACHINE” button, the siren will sound and the signal light will flash yellow. Confirm that the personnel are in the safe area, press "machine on" again, the button light is always on, the machine starts and accelerates to the input set speed.
15. If necessary, perform parent roll adjustment, brake tension adjustment, and flattening roller position check at low speed.

Causes, countermeasures and effects on the quality of BOPP film slitting quality ---

(2) The purpose, method and characteristics of hardness testing
1. OBJECTIVE: The hardness test method provides a quantifiable means for determining the tightness of the film roll and provides a quantifiable basis for the determination.
Some of the product quality characteristics can be quantitative, and some can not be quantified, can only be qualitative. In the past, our judgment on the tightness of the film winding is only based on the hand feeling. The scale of the judgment is difficult to grasp, and the difference between different inspectors Larger. In actual work, when measuring, the non-quantitative characteristics are usually converted into quantifiable substitute quality characteristics, which are used as the basis for evaluation, inspection and assessment. Film roll hardness testing is a means of quantitative control of the main quality characteristics of the slitting under this guiding ideology. However, it is worth emphasizing that not all quality characteristics must be quantified, especially the film as a process material quality characteristic, there are quantitative measurement characteristics, such as thickness, tensile strength, gloss, etc., also have qualitative characteristics, only the process Subjective judgments such as wrinkles, blots, chromatic aberrations, etc.

2. Several characteristics of film roll hardness
1 Different film varieties, the hand tightness is similar but the hardness data is different. This is because the hand roll is used to squeeze the film roll in a certain area of ??the finger, which is a test of one surface, and when the hardness tester is used, it is a The pin point is pressed against the film roll, which is a detection of a point, and there will be differences between the two;
2 different film varieties have different winding hardness requirements, which are based on the characteristics and uses of various films;
3 The tightness and hardness of the film roll are not completely linear. The most sensitive value is between 87 and 95. When the hardness is as low as 85, the rewinding does not affect the hardness. Similarly, when the hardness is high. At 97 o'clock, the effect of rewinding on the film roll hardness is getting smaller and smaller.
4 Winding hardness is a reference index for quantifying the winding tightness. It only reflects a quality characteristic of the film roll surface and does not reflect the fullness of the film roll. Therefore, the key is to effectively control the film roll tightness. The quality of the product used.
