Detalhes do produto

A máquina de impressão de copos de plástico é um equipamento especializado usado para imprimir padrões, logotipos, texto e outros conteúdos na superfície de copos de plástico. Ele utiliza tecnologia de impressão avançada para obter alta precisão e impressão de alta qualidade em copos de plástico de várias formas e tamanhos. É amplamente utilizado em indústrias como embalagens de alimentos, bebidas e catering.

Specialized Equipamento de impressão para copos de plástico descartáveis.

O principal desafio deste equipamento de impressão altamente especializado reside na obtenção de impressão de padrão multicolorido de alta qualidade na superfície plástica cônica e não absorvente.

I. Introdução ao trabalho (fluxo de trabalho)

O fluxo de trabalho de uma máquina de impressão offset totalmente automática pode ser resumido nas seguintes etapas principais:

Automatic Alimentação: Os trabalhadores colocam copos de plástico empilhados na tremonha do equipamento.Através de um dispositivo de separação automática (como uma roda estelar), os copos são separados um por um de maneira ordenada e transportados para porta-copos na corrente de transmissão ou correia transportadora. Tratamento

Pre-Printing (Crucial) - Tratamento Corona: Os copos de plástico (especialmente o material PP) têm baixa energia superficial e são inertes, dificultando a adesão da tinta.

Antes da impressão, os copos passam por um dispositivo de tratamento corona. Este dispositivo usa descarga de alta tensão para alterar a estrutura molecular da superfície do copo de plástico, aumentando a energia e a rugosidade da superfície, melhorando significativamente a adesão da tinta e evitando que os padrões impressos descasquem.

Positioning e transporte: Os copos são posicionados com precisão em porta-copos acionados por servo motor. Cada porta-copos pode girar durante o transporte. Esta é a chave para obter uma impressão uniforme na superfície cônica.

Printing: Esta é a tinta central. Quando os copos passam intermitentemente por cada unidade de impressão com a corrente de transmissão:

Sistema de entrega de tinta: Tira tinta da fonte de tinta e, por meio de uma série de rolos de tinta (rolo condutor, rolo vibratório, rolo distribuidor), uniformiza a tinta e a entrega ao cilindro da chapa.

Tinta: Até a tinta é aplicada às áreas da imagem da placa de impressão (placa de relevo ou resina).

Primeira placa de transferência para o cobertor: O cilindro da placa entra em contato com o cilindro do cobertor, transferindo a tinta das áreas da imagem da placa para a manta de borracha elástica.

Segunda transferência - Cobertor para Copo: O cilindro da manta, carregando a tinta, pressiona a superfície do copo plástico giratório. Devido à elasticidade da manta, ela se adapta bem à superfície cônica do copo, transferindo completamente o padrão.

Cada unidade Uma máquina com 6 unidades realiza impressão em 6 cores; 6 unidades realizam impressão em 6 cores. Todas as cores são impressas sequencialmente em uma única passagem, formando o padrão de cor completo.

A secagem e a Curing

Plastic não são absorventes, de modo que a tinta impressa não pode secar rapidamente através da penetração como no papel.

Após a impressão, os copos entram imediatamente em um sistema de cura UV. A irradiação de luz UV (ultravioleta) de alta intensidade faz com que os componentes de resina fotossensíveis na tinta UV se polimerizem, solidificando a tinta do líquido para o sólido em frações de segundo, aderindo-a firmemente ao copo. Este processo é rápido, não envolve voláteis e é ecologicamente correto.

Automatic Collection

The copos curados são transportados para a seção de coleção.

Por meio de mãos mecânicas ou chutes, os copos são empilhados novamente para embalagem do trabalhador ou conectados diretamente ao próximo processo de produção (como manga, boxe).
