Sheet preheating horizontal conveyance upwarping control mechanism for metal decorating machine

Abstract

The invention discloses a sheet preheating horizontal conveyance upwarping control mechanism for a metal decorating machine. The sheet preheating horizontal conveyance upwarping control mechanism comprises a sheet preheating device connected between a cleaning device and a material pushing mechanism. The sheet preheating device comprises a drying box and a cyclic heating mechanism communicating with the drying box. The two longitudinal sides of the drying box are provided with a sheet feeding inlet and a sheet discharging outlet. Two pairs of rubber rollers are arranged on the cleaning device up and down in the longitudinal direction, and the outer side face of a driving side machine body plate of the cleaning device is provided with a rubber roller end face gear. Two rows of hot gas pipes with gas outlets are arranged inside the drying box up and down. A row of carrying shafts are arranged between the upper and lower rows of the hot gas pipes, and each carrying shaft is sleeved with a plurality of cushion wheels in a positioning mode. A synchronous driving mechanism for the carrying shafts is arranged on a driving side machine body plate of the drying box. The driving side machine body plate of the cleaning device is provided with a bridging driving mechanism passing through the gap between the rubber roller end face gear and the synchronous driving mechanism for the carrying shafts. A sheet preheating horizontal conveyance upwarping control mechanism body is arranged inside the drying box and comprises magnetic wheels which are positioned every two adjacent cushion wheels on the carrying shafts in a sleeving mode. Stable operation of sheets can be guaranteed while product quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and relates to an iron printing machine, in particular to a sheet preheating horizontal conveyance control mechanism for an iron printing machine. Background technique [0002] In the production of tinplate printing, the drying of coatings and inks is a complex physical and chemical reaction process. Because tinplate is insoluble in water and does not absorb solvents, generally before entering the iron printing machine for ink coating, the surface of the metal sheet is primed and dried with paint, but if the drying effect of the paint surface is not ideal, the surface will appear sticky and incomplete Curing will affect the post-printing effect. If the coating and ink are not dry enough to cause the paint film to be tender, the surface pattern will be easily changed or scratched, especially when it is used as a container material for canned food or beverages. If the food or beverage c...

Problems solved by technology

[0005] However, due to the light weight of the iron sheet itself, the sheet is preheated from the inlet of the sheet preheating device to the outlet During the conveying process of the mouth, it is easy to appear the upward phenomenon, which leads to a new technical problem of deviation during the conveying process, which seriously affects the smooth operation of the sheet.
