Rubber calender usually consists of two or more rollers arranged in a certain form, which will rotate relative to each other under power drive. In general, there is a certain speed ratio between adjacent rollers, such as the speed of one roller is faster than that of another roller, which can make the rubber material be better squeezed and shear between the rollers.
When the machine is started, the raw glue or compound is placed between or above the two rollers, and the compound is pulled into the gap between the two rollers due to the friction generated by the rotation of the rollers.After the rubber material enters the roll gap, it will be subjected to strong shear and extrusion action.
The linear speed difference between the two rollers causes the rubber material to suffer uneven force between the roller gaps, resulting in a shearing effect, which cuts the macromolecular chain of the rubber material like scissors. At the same time, the molecular structure of the compound changes due to the extrusion of the roller, and the constant change of the gap also causes the compound to be repeatedly squeezed and stretched.
With the continuous rotation of the roller, the extrusion pressure of the rubber material in the roll gap gradually increases. The section of the roll gap is gradually reduced, so that the rubber material is subjected to strong extrusion and shear. In this process, on the one hand, the adhesive material has viscous flow and constantly expands and deforms; On the other hand, elastic deformation can occur. These two deformation processes are closely related to the fluidity and viscoelasticity of the compound.
After the extrusion and shearing action of the roller, the rubber raw material is rolled and formed. According to different production needs, the film can be made with a certain thickness and width, or the rubber material can be squeezed on the skeleton material such as textile and steel cord to complete the hanging operation, and the operation of the rubber embryo pressing and the lamination of multi-layer film can also be carried out
1.The cylinder ( piston ) adopts the best seals structure , with reasonable design and reliable function. The seals part is good quality YX typepolyurethane seals (not rubber seal ) ,which is oil resistant , aging resistant .Our machine adopts the double seals structure , and seals part is easy change and protect
2.Automatic control : automatic mold closing , automatic exhausting , automatic heating and keep stable temperature, automatically timing for vulcanization , automatic alarming , automatic mold opening ,etc
3..The vulcanizing temperature can be set and showed in the digital displan .
4.Vulcanizing time can be set in the PLC screen . If you want to heat and vulcanize for 1 minutes , just set it directly . When it reaches 1minutes ,machine will alarm then machine will open the mold automatically
5.Pillar is made of high quality # 45 steel, The hardness , wear resistance and abrasive resistance is high improved by quenching and tempering
6.The top beam and bottom plate form is welded with the good quality Q-235A ductile iron .After welding , it is also processed by the artificial vibration or high temperature aging treatment , to eliminate the internal stress and avoid the deformation
7.plunger is made of LG-P cold hard alloy steel . Surface of it owns high hardness and wear resistant.Depth of chilled layer is 8-15mm , hardness is HRC 60-70 , making the plunger own long life time
