Embodiment Construction

[0029] figure 1 The appearance of the guide roller 10 of this embodiment is shown. The guide roller 10 is composed of an outer roller 12 and an inner roller 14 respectively shown in FIG. 2(A) and FIG. 2(B). An O-ring 16 shown in FIG. 3(A) is attached to the inner roller 14 . The journals 18 and 20 and the rotary joint 22 respectively shown in FIGS. 4(A) to 4(C) are attached to the guide roller 10 . The outer roller 12 and the inner roller 14 are respectively fixed by journals 18 and 20 and rotate together in the circumferential direction.

[0030] Referring to FIG. 2(A), the outer roller 12 has a cylindrical shape along the axis AX1. The outer roller 12 is made of, for example, stainless steel, aluminum, iron or resin. The overall length of the outer roll 12 is several hundred mm, and the thickness of the outer roll 12 is in the range of several mm to several tens of mm. The outer diameter of the outer roll 12 is defined by the outer peripheral surface PR11 of the outer r...

Abstract

The invention provides a guide roller, a film conveyance apparatus, and a sheet forming machine which can dynamically adjust the shape of the periphery of the guide roller. The guide roller (10) has an outer roller (12) having an axis (AX1), and an inner roller (14) which has an axis (AX2) coinciding with the axis (AX1) and is received in the outer roller (12). The outer roller (12) has multiple slits (SL1 To SL3) formed in the periphery (PR11). Being viewed radially, the inner roller (14) has multiple holes (HL1a to HL3a, HL1b to HL3b) which go into a hollow part from the periphery (PR21) and which are arranged in positions avoiding the multiple slits (SL1 To SL3). The multiple holes (HL1a to HL3a, HL1b to HL3b) are surrounded by annular grooves (GR1a to GR3a, GR1b to GR3b). The multiple slits (SL1 to SL3) are formed in the outer side of the annular grooves (GR1a to GR3a, GR1b to GR3b). The periphery (PR110) of the outer roller (12) is pressed against a to-be-guided conveyance object.

Description

technical field [0001] The present invention relates to a guide roller, a film conveying device, and a sheet forming machine. Background technique [0002] of Patent Document 1 figure 1 An extrusion sheet forming machine is described in . This sheet forming machine includes: a film conveying device that conveys a strip-shaped carrier film, a coating device (die) that coats a slurry on the surface of the conveyed carrier film, and a coating device (die head) that coats the coated slurry. Dry drying unit. The film conveying device includes an unwinding unit that supplies the carrier film from a support roll, a conveying unit that conveys the carrier film, and a winding unit that winds the carrier film into a roll. A pair of guide rollers for guiding the carrier film to the discharge port of the die are present on the conveyance path of the carrier film. The carrier film is conveyed in a state of being in contact with the guide surface (roll surface) of the guide roller. B...
