Adhesive Jumbo Roll Tape Slitter Machine

Adhesive Jumbo Roll Tape Slitter Machine

Slitting machine starts production
1. The winding roller is pressed down, the counter is cleared, and the production is started;
2. During the operation process, check the winding status of each joint from time to time, and adjust the tension according to the tightness of the winding to make each volume
The material is wound up and the end face is flush and firm;
3. Always pay attention to product quality during machine operation.
4. The machine has no abnormal sound.
5. Whether the photoelectric tracking operation is normal.
6. When checking the next volume, pay attention to check the surface of the product for quality defects and stick the tape as required.

(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 ---
two. Wrinkles (wrinkles, vertical wrinkles, cross wrinkles, wrinkles)

With the continuous improvement of slitting technology, the length of wrinkle is becoming less and less, and the products of individual manufacturers have achieved zero wrinkle, which undoubtedly grasps the opportunities in the fierce competition environment. It is worth noting that the wrinkles that we sometimes appear are not caused by the unreasonable setting of the cutting parameters, but because our operators are not responsible for the work, and the film is not attached to the paper tube but is free. After the film is put on the paper tube, it is turned on and cut, and the quality of the wrinkle is artificially created. It must be paid attention to, eliminate the defects of human quality and improve the quality of the product.
