Slitting machine operating procedures -

Second, the volume of the replacement of the finished product (operating station)
1. Press and hold the “winding side 1 swing” and “winding side 2 swing” buttons until the finished roll leaves the press roller (winding arm vertical state). 2. At the same time, the blades cut off the finished product on both sides, and the end of the film is glued to the finished roll as the end mark of the finished roll. 3. Continue to press and hold the “winding side 1 swing” and “winding side 2 swing” buttons, and the winding arm will open to both sides until the finished product rolls over to the unloading trolley tray and release the button.
4. Press the “Release side 1 card head release” and “Rewind side 2 card head release” buttons, the card head will open, release the finished product roll (if the finished product roll does not come down, manually shake the finished product roll).
5. Press and hold the “winding side 1 swinging” and “winding side 2 swinging” keys, and the winding arm station will be turned up and forward until the winding arm reaches the paper discharge core position and release the button.

6. Unload and unwind the trolley and advance the finished product to the packaging area.
7. After the winding arm is in the correct position, manually install the empty paper core (the double-sided adhesive should be attached to the paper core).

(2) The purpose, method and characteristics of hardness testing

 

3. Method for detecting film roll hardness
1 selection of testing equipment
There are various instruments for detecting the hardness of an object, but so far there has not been a hardness tester that professionally detects the hardness of a film roll. Due to the large difference in surface hardness between various objects and the variety of hardness testers, it is important to select a hardness tester that can effectively reflect the tightness of the film roll. After screening and comparison, our company has determined the "A-type rubber hardness tester" for detecting the surface hardness of rubber products as an auxiliary instrument for detecting the tightness of the film roll.
2 detection instrument correction
Since the "A type rubber hardness tester" is not a special test instrument for the film roll, in order to improve the detection accuracy of the instrument, we have modified the structure of the hardness tester according to the characteristics of the film, and increased the presser area by 5 times.
3 detection methods a.
Before the test, the pointer of the hardness tester should be in the free state and point to the zero position. When pressing the hardness tester on the glass plate, the pointer should be 100 degrees (the end face of the press pin and the bottom of the foot are in close contact with the glass). If the zero position and the 100 degree are not indicated, the needle can be pressed slightly several times, if not When referring to zero and 100 degrees, it cannot be used. The hardness tester to be confirmed can be used again if it meets the requirements for use. b.
When testing the hardness, put the hardness tester on the side of the film product, take the left, middle and right positions, at least 40mm from the edge of the film roll, and firmly press the end of the hardness tester with both hands, so that the pressure pin is pressed vertically. The sample is read within 1 s until the pressure is fully contacted with the sample, and the average is taken and recorded.

Reasons, countermeasures and effects of BOPP film slitting quality ---

nine. Scratch
      Whether the slitting and scratching can be compared and determined by the film surface before and after the slitting, there are various reasons for the scratching of the membrane surface, and the analysis should be based on the appearance of the scratch, such as short-line scratching. The difference of the speed ratio of each drive roller exceeds the process setting requirement, and it needs to be carefully tested and adjusted. If the film surface scratch occurs continuously, the film on the slitter should be inspected for whether it touches the fixed object or cuts each. Whether the roller adheres to dirt such as fine sand grains scratches the film surface.
Scratch is the appearance quality problem of the film, which directly affects the quality appearance of the deep-processed product. Therefore, it is not allowed to exist in the film quality control standard. The slitting process finds that the scratching problem must be carefully checked and quickly eliminated. Since the scratch on the film surface is an irreversible appearance quality problem, it is not allowed to operate the disease when the film surface is scratched, so as to avoid the continuous occurrence of the problem.
