Slitting Machine For Adhesive Tape

Slitting Machine For Adhesive Tape

Slitting adjustment
1. Put the cutter down, open the curling blower switch, set the winding tension, start the machine, run 2-3 meters, stop;
2. Measure the width of each joint to confirm whether the requirements are met. If there is any error, the ratio of the cutter should be re-matched.
3. Check whether each of the paper cores and the corresponding film are aligned, otherwise adjust them;

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

(iv) Effect of film roll tightness on product quality

(5) Coping methods
1. Reasonable principle: Applicable is reasonable, which means that the cutting operator and the quality inspector are too loose according to the winding/
Too tightly influence the degree of influence on different products, adjust the cutting process reasonably, and reasonably grasp the tightness of the film roll to meet the requirements of the use of film products.
2. Ningsong Motight principle: objective when cutting equipment status, product specifications, film performance characteristics, etc.
When the influence of the condition causes the winding tightness to be in an inappropriate degree, the principle of tightness is generally used, because the problem of over-tightening often makes the film unusable, except for the special requirements.
3. The principle of primary and secondary: it means that in the process of slitting production, small groups should be followed to the interests of large collectives.
The principle of benefiting the interests of the company, avoiding the pursuit of high output and high distribution for the purpose of reducing the quality of cutting, all should be based on product quality, maintaining the German crown film brand as the responsibility, effectively completing various production and quality indicators Effectively serve the enterprise and users, and strive to be the best supplier of film.
4. System Management Principles: Refers to the use of systematic, scientific management methods, practical, theoretical, and empirical
The accumulated cutting control method is compiled, and according to the optimal combination of different types of products, width, winding length, season and other external variables and slitting tension, pressure and other internal variables, the document control management is performed to form an operation guidance document. Minimize the influence of subjective factors, reduce the impact caused by insufficient individual ability or excessive dependence on experience, and continuously supplement, optimize and improve the operation guidance documents to meet the needs of system management.

two. Wrinkle (wrinkle, vertical wrinkle, cross wrinkle, line wrinkle)

Through many years, the BOPP industry has carried out a series of intensive and meticulous work on solving the problem of wrinkling. From the two aspects of process parameter screening and equipment adjustment and transformation, we have found a set of effective solutions and received very good results. effect,
Methods include:

5 Under the same parameters, the long gauge is more likely to wrinkle than the short gauge film roll, which means that the longer the specification, the worse the exhaust effect, and the lower the strength of the long gauge paper tube, the slitting process paper The slight bending of the tube tends to cause the film in the middle of the film roll to wrinkle for a long time, and when the paper core is long, under the high-speed rotation of the slit, as the axis of the film winding, its straightness, concentricity, strength, The indicators such as surface finish are the most important. Generally speaking, the longer the paper core, the more difficult it is to ensure the straightness and concentricity. Therefore, the quality of the paper core is very important. It is necessary to improve the inspection of the paper core. If the paper tube is found during the slitting process, the paper tube is found. The quality is abnormal and needs to be replaced in time. In addition, under the same parameter conditions, the short gauge is more prone to deviation than the long gauge membrane coil, and a large winding pressure is required. Therefore, for the adjustment of the wrinkle, the wrinkle can be reduced by appropriately reducing the pressure setting for the long specification, and the pressure is increased for the short specification to prevent the deviation;
6 Different thickness films have different degrees of wrinkling, thick film stiffness is better, less wrinkles, thin film is more open, so the thin film should be adjusted to increase the strength of the parameters to overcome For the generation of wrinkles, different thickness of the film should have different special data for slitting;
7 The product that is slit inside and outside the slitting machine may have different degrees of wrinkling due to the different angles (wrap angles) entering the winding roller. The difference between the inner and outer wrinkles of each slitting machine should be compared, such as The difference is obvious. During the slitting process, the specification that is prone to wrinkle should be cut on the side that is not prone to wrinkle;
8 The wrinkle reduction can also be achieved by adjusting the venting performance of the pressure roller and improving the stability of the winding arm.
