Thermoplastic extrusion rolling device for PC endurance plate

Abstract

The invention belongs to the technical field of thermoplastic equipment and particularly relates to thermoplastic extrusion rolling device for a PC endurance plate. The device includes a base, a pressure bearing plate is fixedly mounted on a top side of the base, side plates are fixedly mounted on two sides of the base, a rotating roller, an upper pressing roller and a lower pressing roller are arranged between the two side plates, one end of the rotating roller penetrates through the side plates and is provided with a driving motor, the rotating roller is fixedly sleeved with a driving gear,and a driving chain is arranged on the driving gear. The upper pressing roller is located over the lower pressing roller, one end of the upper pressing roller penetrates through the side plates and isfixedly connected with a driven gear in a sleeved mode, the driven gear is connected with the driving chain in a sleeved mode, a PC plate is arranged between the upper pressing roller and the lower pressing roller and located between the rotating roller and the pressure bearing plate, a cross beam is fixedly installed between the two side plates, and a plurality of rigidity lifting devices are fixedly installed on a bottom side of the cross beam. The device has the advantages of high rigidity, small driving force, energy saving and emission reduction and can prevent the PC endurance plate from being easily bent and broken.

Description

technical field [0001] The invention relates to the technical field of thermoplastic equipment, in particular to a PC endurance board thermoplastic extrusion rolling device. Background technique [0002] PC endurance board, also known as Kablon endurance board, polycarbonate solid board, PC bulletproof glass, PC solid board, polycarbonate board, is made of high-performance engineering plastic polycarbonate. In the production process of PC endurance board, the material needs to be thermoplastically extruded and rolled into shape. [0003] At present, the rolling of PC solid sheet is generally carried out by a large-diameter two-roll or four-roll rolling mill, and the PC solid sheet is too thin after rolling, resulting in insufficient toughness. The diameter is directly proportional. If a large-diameter two-roll mill is used to roll a thin plate, the elastic flattening value of the pressure roll itself is often greater than the reduction of the plate to be rolled, making the ...

Problems solved by technology

[0003] At present, the rolling of PC solid sheet is generally carried out by a large-diameter two-roll or four-roll rolling mill, and the PC solid sheet is too thin after rolling, resulting in insufficient toughness. The diameter is directly proportional. If a large-diameter two-roll mill is used to roll a thin plate, the elastic flattening value of the pressure roll itself is often greater than the reduction of the plate to be rolled, making the PC solid sheet easy to bend and break, and when the roll diameter When it is larger, the contact area between the pressure roller and the plate is large, and the rolling force required for rolling the plate is also large; and when the diameter of the pressure roller is small, the corresponding problem of insufficient rigidity of the pressure roller will appear.
