TECHNICAL FIELD
[0001] The present application relates to the technical field of paper slitting, in particular to a paper processing device. BACKGROUND
[0002] In the processing flow of transfer paper, the slitting process is a crucial link, which aims to accurately slit the large-size raw paper roll obtained by purchase into several small-size finished paper rolls according to the specific needs of downstream customers.
[0003] The common practice in the current industry is to use forklifts and other handling equipment to transport raw paper tubes with large weight and volume to the slitting machine and erect them on the unwinding mechanism of the slitting machine. Then, the slitting machine drives the paper roll to rotate through a series of complex mechanical and electrical control systems, and uses high-precision cutters to slit it radially into paper rolls with smaller width, and finally the winding mechanism neatly winds the slit paper roll into shape.
[0004] However, the existing slitting machine equipment, especially those industrial-grade slitting machines that can handle wide and large-diameter raw paper rolls, generally have the problems of complex structure and large size. For example, the length of the slitting machine equipment can reach 8-10 meters, the width exceeds 3 meters, the height is close to 2.5 meters, and the floor area is equivalent to the size of an ordinary family living room. Such a large machine size, on the one hand, requires a large amount of steel, castings and other raw materials in the manufacturing process of the equipment, and the integration of precision transmission systems and intelligent control systems leads to a purchase cost of a single equipment exceeding one million yuan; on the other hand, when planning the layout of the factory, the enterprise not only needs to reserve enough installation space, but also needs to consider the maintenance channel, material transportation channel and other supporting areas during equipment operation, which puts forward strict space requirements for the production site. According to industry statistics, such large slitting equipment will occupy an average of 15%-20% of the total area of the factory, which seriously compresses the available space of other production links and greatly limits the flexibility of production layout. In addition, the large size of the equipment also brings high energy consumption, including power consumption, daily maintenance cost, equipment depreciation cost, etc., which further increases the fixed asset investment and operating burden of the enterprise, makes the production cost high, and affects the profit space of the enterprise in market competition.
