Abstract
A vertical double-sided rotary screen transfer printing apparatus includes a vertical rack and one or more pair of rotary screen transfer printing assemblies horizontally disposed opposite to each other. Each rotary screen transfer printing assembly includes a rotary screen plate roller and a transfer roller arranged parallel to each other. The rotary screen plate roller transfers a pattern onto the transfer roller serving as a temporary transfer carrier. The transfer roller transfers the pattern onto a fabric passing in a vertical direction between the rotary screen transfer printing assemblies opposite to each other.
Claims18
A vertical double-sided rotary screen transfer printing apparatus, comprising a vertical rack and at least one pair of rotary screen transfer assemblies horizontally disposed opposite to each other, each of the rotary screen transfer assemblies comprising a rotary screen plate roller and a transfer roller arranged in parallel with each other, the rotary screen plate roller transferring a pattern onto the transfer roller as a temporary transfer carrier, and the transfer roller transferring the pattern onto a fabric passing in a vertical direction between the transfer rollers of the rotary screen transfer assemblies arranged opposite to each other;
- wherein each of the rotary screen transfer assemblies further comprises a scraper assembly, the scraper assembly comprises a scraper disposed in the rotary screen plate roller, and a position and a pressure of the scraper relative to the rotary screen plate roller are adjusted using a scraper adjustment mechanism;
- wherein the scraper adjustment mechanism comprises a primary adjustment mechanism and a secondary adjustment mechanism;
- wherein the primary adjustment mechanism comprises a swing arm and a swing arm actuating apparatus for actuating the swing arm, the swing arm comprises a first swing arm portion and a second swing arm portion, one of two ends of the first swing arm portion is connected to the swing arm actuating apparatus, the other end of the first swing arm portion is fixedly connected to the second swing arm portion at an angle, a pivot portion is provided on the first swing arm portion, so that the first swing arm portion is pivotable around the pivot portion when being actuated by the swing arm actuating apparatus, a pivoting of the first swing arm portion allows the second swing arm portion to move accordingly, and a movement of the second swing arm portion allows the scraper to move close to or away from an inner surface of the rotary screen plate roller;
- and
- wherein the secondary adjustment mechanism comprises a secondary scraper pressure adjustment assembly and a secondary scraper position adjustment assembly, the secondary scraper pressure adjustment assembly is arranged on the first swing arm portion for adjusting a contact pressure between the scraper and the rotary screen plate roller, and the secondary scraper position adjustment assembly is arranged on the second swing arm portion for adjusting a position of the scraper in the rotary screen plate roller.
