Performance parameters and structural arrangement of non-woven calender

- Nov 13, 2018-

The non-woven calender is a product which is arranged in a certain form by two or more rolls, and is pressed into a certain thickness and surface shape at a certain temperature, and the cloth can be glued. Machinery.


The non-woven calender can be divided into two rolls, three rolls, four rolls and five rolls calender according to the number of rolls; according to the arrangement of the rolls, it can be divided into "L" type, "T" type, "F". Type, "Z" type and "S" type, etc.


The non-woven calender is mainly composed of a roller, a frame, a roller distance adjusting device, a roller temperature adjusting device, a transmission device, a lubrication system and a control system. There are many performance parameters, including the number of rollers and their arrangement, the diameter and length of the roller, the speed range of the roller, the speed ratio and production capacity, the minimum thickness and thickness tolerance of the rolled product, and the transverse pressure of the roller. And drive power, etc.


Unlike other machines, the non-woven calender consists of a frame, a press roll and its adjustment device, a transmission system and a heating system. The frame is usually made of cast iron and mounted directly on either side of a cast iron or cast steel stand. It is used to support the pressure roller bearing, the shaft crossing or the pressure roller pre-bending device, the pressure roller adjusting device, the lubricating device and other auxiliary devices.


The press roll is made of chilled cast iron and cast steel, and its aspect ratio is selected according to the bending strength of the press roll material, which is about 2.6 to 3.5. In order to compensate for the defects of uneven thickness of the product caused by the bending deformation caused by the force of the pressing roller, the pressing roller is mostly formed into a waist drum shape, and the thickness unevenness of the product can be eliminated by the roller crossing device and the roller pre-bending device.
