The rubber calender is generally composed of a work roll, a frame, a machine base, a transmission device, a speed, and pitch adjustment device, a roller heating and cooling device, a lubrication system, and an emergency stop device. There are many types of calenders. To meet different technological requirements, there are two, three, and four rolls in total. The following will introduce you several common types of rubber calenders.
Here is the content list:
What is a three-roll rubber calender?
What is an S-shaped four-roller rubber calender?
What is a four-roll inverted L-shaped rubber calender?
The three-roller rubber calender is installed in parallel on the machine base with two frames connected by upper beams, and three pairs of roller bearings and three rollers are installed on the frame. The bearings of the middle roller are fixed on the frame of the rubber calender machine, and the bearings of the upper and lower rollers are respectively connected with the adjusting screw. Use a motor or a handwheel to complete the roll pitch adjustment work through the vertical rod, worm gear, and worm gearbox. Use claw clutches 17, 18 to control the adjustment of the upper and lower rollers, and claw clutches 19 and 20 to control the adjustment of the left and right ends respectively. The roller distance indicator indicates the size of the roller distance. The safety device is used to control the adjustment range of the roller pitch and emergency stop.
The advantages of the S-shaped four-roll rubber calender are high speed, high precision, and can improve production capacity and product quality. The roller of the S-shaped four-roller rubber calender is made of alloy chilled cast iron, which adopts the drilling type and uses the automatic temperature adjustment mechanism of the superheated water circulation method to adjust the temperature of the roller. The four rollers are arranged in an S shape, so that not only the force is reasonable, but also the operation is convenient. These four rollers are driven by a reducer and a universal coupling by two motors. The speed regulating device is adjusted by a thyristor, which saves electricity, has high efficiency, is small in structure, and is easy to maintain, so it can be glued without changing the process. Wipe glue or calender film. The S-shaped four-roll rubber calender is equipped with an automatic thickness gauge and an automatic temperature recording and measuring device, which can automatically control the thickness of the product and the temperature of the roller.
The characteristic of the four-roll inverted L-shaped rubber calender is that the rollers are arranged in an inverted L shape, and a set of speed ratio gears are installed on both sides of the roller; the pitch adjustment device is driven by a separate motor; the motor is perpendicular to the output shaft of the reducer The layout reduces the floor space. The four-roll inverted L-shaped rubber calender is widely used in the production of tires and tube belts.
