PVC Sheet Calendering Production Invented May 10, 2017

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a method for producing a multilayer rubber sheet and a calendering production line thereof, and more particularly to a rubber sheet having a multilayer structure having a multilayer structure using a symmetrical laminated composite calendering production line.

Rubber sheet in a variety of industries have been widely used, especially multi-layer rubber sheet, because of its excellent mechanical properties, in all walks of life applications more and more attention. The existing rubber sheet rolling production line can meet the preparation of a single and very few layers of rubber sheet, for the preparation of microstructure of multi-layer rubber sheet, especially the use of a small amount of calendering machine can not achieve mass production.

DISCLOSURE OF THE INVENTION It is an object of the present invention to provide a simple laminating composite method and a calendering production line suitable for preparing a multilayer rubber sheet for the production of a rubber sheet having a multilayer microstructure in view of the failure of the conventional calendering production line, The laminated composite method and the rolling production line method are simple, the required equipment is small, compact structure, easy to implement.

The technical scheme adopted by the invention is a multi-layer rubber sheet laminated composite rolling production line, which comprises: a calender, a steam generator, a # 1 coating drying zone, a 2 # coating drying zone, The coating drying zone and the 2 # coating drying zone are symmetrically arranged on both sides of the calender and the number and working conditions of the 1 # coating drying zone and the 2 # coating drying zone are the same.

According to the present invention, there is provided a multi-layer rubber sheet laminated composite rolling line comprising a coating machine, a drying roller, a sliding rod, a far infrared heater, A drying machine is arranged on the upper side of the coater and the drying roller, the far-infrared heater is mounted on the sliding rod, and the drying rod is arranged on the slide bar, After the machine is installed in the far-infrared heater, the winding device is set behind the dryer.

According to the present invention, there is provided a multi-layer rubber sheet laminated composite rolling production line, wherein the calender is equipped with a frequency converter and a forward / reverse circuit, and the positive and negative rotation of the calender roll can be realized.

According to the present invention, there is provided a multilayer rubber sheet laminated composite rolling production line which is provided on one side of a calender and is provided with a calendering roll for a calender for an operating temperature required for rolling a multilayer rubber sheet Heating up and cooling.

A multi-layer rubber sheet laminated composite rolling production line is fixed on a ceiling of a plant, and a far infrared heater is mounted on a slide bar so as to be freely slidable on a slide bar.

According to the invention, there is provided a multilayer rubber sheet laminated composite rolling production line, wherein the dryer has upper and lower two-layer channels, and the upper and lower two-layer channels are arranged in parallel.

According to the present invention, there is provided a multilayer rubber sheet laminated composite rolling production line, wherein the take-up device is provided with n rubber sheet take-up rollers and a frequency conversion governor and a forward / reverse circuit, n take-up rollers In the vertical direction of the winding device in parallel arranged in parallel, and in the same drive motor under the rotation movement.

The multi-layer rubber sheet laminated composite calendering production line according to the number n of the unwinding rolls and the number of calendering m, and finally, M-1) layer having a microstructure. N and m are integers greater than 2.

The multi-layer rubber sheet laminated composite rolling production line comprises the following steps:

Step 1 uses the steam generator to heat the calender of the calender to achieve the required operating temperature;

The process 2 uses a calender to calend the compound provided by the extruder or other equipment and adjust the baffle of the calender to a suitable width to press out the desired width of the rubber sheet;

Step 3 The coating film of the pressed rubber sheet was coated with a # 1 coater;

Step 4 The rubber sheet after the coating was softened by a # 1 drying roll and initially heated and dried;
