Abrégé

The present invention relates to a belt mounting mechanism and a multifunctional bronzing device that uses said mechanism. The mechanism comprises: a microporous belt, a conveying roller, an adjusting roller, a fixing plate, an adjusting plate, and two adjusting components. The belt mounting mechanism and the multifunctional bronzing device that uses said mechanism implement connection and support between the fixing plate and the adjusting plate by being provided with the adjusting components, which helps the level of the microporous belt to be conveniently adjusted. In addition, by means of the detachable design of the adjusting components, sleeving and mounting of the entire microporous belt can be facilitated, so that the stacked connection of the microporous belt can be avoided, increasing the flatness of the microporous belt and improving the separation effect while increasing the punchable area and the number of air suction holes and improving the adsorption effect.

Provided is a fully automatic cold stamping machine of a rotating wheel type, the cold stamping machine comprising a frame body (a), a sealed box (b), an infrared pre-heater (d), a vacuum suction mechanism (m), and a conveyor belt mechanism (c) mainly formed by a preceding-stage hot stamping conveyor belt (5) and a post-stage hot stamping conveyor belt (6); a pre-printing curing device (e), an aluminium foil loader (f), an aluminium foil recoverer (h), an in-printing curing device (n), and a post-printing curing device (k) respectively located within the sealed box (b); and a cold stamping rubber roll mechanism (g) formed by a rotating wheel main roller (7) and two hot stamping dandy rolls (8, 9). A hot stamping part of the cold stamping machine uses a structural form of one rotating wheel main roller (7) cooperating with two hot stamping dandy rolls (8, 9), can perform two-sided press fitting and transfer printing treatment on an electro-chemical aluminium foil (B) and a printed material (A), and at the same time uses three curing devices (e, n, k) to perform different degrees of curing treatment on glue on the printed material (A) in pre-printing, in-printing and post-printing stages, thereby effectively guaranteeing the integrity of a hot stamping pattern and the hot stamping effect. The cold stamping machine has a simple and compact structure, can guarantee the effects of hot stamping processes such as embossed hot stamping, relief cold stamping and relief laser transfer printing.

A full-automatic silk-screen cold-ironing printing machine, comprising: a frame body (a), a seal box (b), a conveying belt mechanism (c), an infrared preheater (d), a vacuum suction mechanism (m) used for adsorbing a printing stock (A) onto the conveying belt mechanism (c), and a front end curer (e), an aluminum-foil storage (f), an aluminum-foil recycling device (g), a cold-ironing rubber roller mechanism (h) and a rear end curer (k) that are separately located in the seal box (b). A fresh air inlet (3) and an air outlet (4) are formed on the seal box. The cold-ironing printing machine can prevent pollution from an external environment, and effectively resolve the problem of deformation of the printing stock due to excessively high temperature and the problem of deviation or deformation in a conveying process.

A silk screen printing embossment cold-ironing method, comprising: step 1: sucking up sheets in an air suction manner by using a discharging separator, and conveying the sheets out one by one; step 2: conveying the sheets to a color seat by using an air suction belt, and imprinting UV printing ink on the sheets, a UV lamp being used for curing the UV printing ink during imprinting; step 3: coating at least part of the sheets with UV gloss paint by using a reticulate-pattern roller seat; step 4: conveying the sheets to a drying base for curing of the UV gloss paint; step 5: conveying the sheets to a circular screen silk printing base, and printing UV glue on an embossment cold-ironing component; step 6: semi-curing the UV glue of the sheets on the drying base by using the UV lamp; step 7: adhering electrochemical aluminum foil to the UV glue on the sheets by using a gold stamping base, and separating redundant electrochemical aluminum foil from the sheets after completely curing the UV glue by using the UV lamp; and step 8: completing embossment cold-ironing. By means of the technical solution, the adjustment time of a screen printing plate is extremely short, and the productivity speed is greatly increased.
