Paper automatic tin foil machine

Abstract

The invention provides a paper automatic tin foil machine, and relates to equipment for producing tin foil paper. The invention aims to solve the problem existing in the prior production of the tin foil paper that much tin residue is generated in tin liquid in a tin melting slot. In the paper automatic tin foil machine, a machine frame is provided with a pressing roll device comprising an upper pressing roll, a lower pressing roll and a pressing roll gap adjusting mechanism, a drive mechanism, a paper supply axis, a paper collecting axis, a tin melting device and a tin supply device comprising a tin pump and a horizontal flow box, wherein the drive mechanism is connected with a rotary axis of the lower pressing roll; paper on the paper supply axis is connected to the paper collecting axisby the upper pressing roll, and the drive mechanism is connected with the paper collecting axis; an inlet of the tin pump is soaked in the tin liquid of the tin melting slot, and an outlet of the tinpump is inserted in the horizontal flow box; the horizontal flow box is arranged above the tin melting slot, and a strip-shaped tin outlet tongue of the horizontal flow box is parallel to the axial line of the lower pressing roll and arranged on the part of the obliquely upper side of the lower pressing roll, which moves towards the roll face of the lower pressing roll to the highest point; and the lower pressing roll is arranged above the tin liquid of the tin melting slot and close to the tin liquid. Because the rolling of the lower pressing roll does not stir the tin liquid, the tin residue generated in the tin liquid is obviously reduced.

Description

technical field [0001] The invention relates to a device for producing paper with a metal film, especially a device for producing tinfoil paper. Background technique [0002] Tin foil paper or tin foil is a composite paper with a thin film of tin material, which has a wide range of uses among the people. In recent years, tin foil paper has been produced by mechanical calendering. A typical calender has a frame on which upper and lower pressure rollers, a pressure roller gap adjustment mechanism and a driving mechanism are installed, and the driving mechanism is connected to the rotating shaft of the upper or lower pressure roller. The tin-lead alloy sheet is pressed through the calender by the upper and lower rollers, then heated and softened, then the gap between the rollers is reduced, and then rolled repeatedly to form a 30-50 micron tin-lead alloy film. It is then glued to the paper with glue, and finally made into tinfoil. Due to the irregular shape of the tin-lead a...
