Slitting machine operating procedures -
Second, the volume of the replacement of the finished product (operating station)
8. Operate the button on the winding arm to wind up the paper core.
9. Manually cut the film to be cut onto the corresponding rewinding paper core. After tightening the film, it is firmly adhered to the paper core (note that the side 1 and side 2 films are differently worn).
10. After all the paper cores on both sides are glued, press “Crop 1 Clamp” and “Reel 2 Clamp” at the same time, and then press “Rewind side 1 open” and “winding side 2 open” at the same time. The position is automatically swung until the winding paper core is pressed against the upper roller, the winding main body is started, and the film is slowly wound until it is tight. (The two-button white indicator light turns from blinking to steady light)
11. 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.
12. The main operator shall check the winding condition of each film and fine-tune the winding arm if necessary.
Reasons, countermeasures and effects of BOPP film slitting quality ---
thirteen. Foreign matter such as dust and small flying insects in the film roll
In the slitting process of the film, the mother roll film needs to be unwrapped and then slit and wound, which creates conditions for the entry of foreign matter. Since many film products themselves need to be in direct contact with foods, medicines, etc., the hygiene requirements are very strict, and the film is not allowed to be attached with foreign objects such as mosquitoes. Once found, it causes major quality complaints and claims, directly causing the company's economic loss and product brand. Damaged and negatively affected, therefore, the environmental cleaning and purification work in the production workshop plays a very important role in ensuring the quality of the film.
Domestic cutting machine development status and outlets ---
1. Not rigorous in the manufacturing process
Tolerance control in the mechanical manufacturing process is not precise enough, and the surface is rough, especially in the matching electroplating industry, which is shoddy. There is a defect in the dynamic balance of the roller for cutting the Chinese-made equipment at one time. The lag of the related industry, the rubber coated by the roller has far less wear resistance and anti-aging than the foreign products. The bearings used seem to use well-known foreign brands, but the counterfeit and shoddy floods the domestic bearing market. Even when the real goods are purchased, the precision is far lower than the precision used by foreign slitting machines.
In the entire production process of a slitting machine, there is no guarantee of production process. At present, most of the slitting machines produced in China are completed by a number of outsourcing units, and the quality of their production is even more difficult to guarantee. In addition, the metal materials used and the heat treatment process are not rigorous enough, resulting in many problems in the use of a slitting machine. It has seriously affected the share of a slitting machine in the domestic market. The secondary and tertiary slitting machines have fewer problems than the one slitting machine, because the parts of the secondary and tertiary slitting machines are completed by the slitting machine manufacturer, and the dynamic balancing machine used is in a narrow range. It can accurately control the unbalanced grams, and the industrial difficulty coefficient of manufacturing is reduced. Its selling price is far lower than that of foreign products. Therefore, the proportion of domestically produced slitting machines in the domestic slitting machine market getting bigger.
