Embodiment Construction

[0042] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0043] exist figure 1 and figure 2 Among them, from the left, there are extruder 1, die 2, rolling roll 3, guide roll 4, traction roll 5 and synchronous trolley 6.

[0044] The extruder 1 heats and melts a thermoplastic resin such as acrylic resin. The thermoplastic resin is heated by the extruder 1, mixed in a molten state, and continuously sent to the mold 2. The heating temperature is equal to or higher than the melting temperature of the thermoplastic resin.

[0045] The heated and melted thermoplastic resin is extruded from the die 2 into a sheet form at a speed of, for example, 10 m / min to 30 m / min. As the mold 2, for example, a normal T-die can be used. The mold 2 can extrude the thermoplastic resin in a single layer, or in a multi-layer extrusion of two layers or more than three layers. Single-layer continuous sheets can be formed by utili...

Abstract

The invention provides a cutting machine capable of cutting rigid synthetic resin plate at high quality, in particular to the wide and thin rigid synthetic resin plate made from rubber and added with little acrylic resin or the like and provides a cutting machine capable of cutting out standard plate without chip from continuously flowing rigid synthetic resin plate. The cutting machine (10) comprises opposite an upper blade (12A) and a lower blade (12B), wherein two side faces of each blade are with elastic components (19A, 19B) protruded than the blades, while the elastic components can clamp rigid synthetic resin plate (7) when in cutting, the elastic components arranged on two side faces of the upper or lower blade are composed of an elastic portion near the blade and an elastic portion far from the blade, while the rigidity of the elastic portion near the blade is higher than the elastic portion far from the blade.

Description

technical field [0001] The present invention relates to a cutting machine for a hard synthetic resin sheet, and particularly relates to a cutting machine for a hard synthetic resin sheet such as acrylic resin which is wide, thin, and has a small amount of added rubber components. Furthermore, the present invention relates to a cutting machine for cutting a continuously flowing hard synthetic resin sheet in the transverse direction to obtain sheets of a standard size. Background technique [0002] There is a method of inserting a cutting blade into both upper and lower surfaces of a hard synthetic resin sheet to generate a starting point of brittle fracture, and cutting by propagating the brittle fracture in the thickness direction of the sheet. This technique has the following features (see Patent Document 1 and Patent Document 2). [0003] • No cutting that cannot be recirculated is produced. [0004] ·Short cutting time. [0005] ·The cutting device or cutting mold is c...
