Full-automatic screen printer

Abstract

The invention discloses a full-automatic screen printer, which comprises a feed system, a transfer device, a positioning and punching device and a traction device, wherein the feed system comprises a tension control system, an edge aligning system and a dedusting wheel; the positioning and punching device is arranged between the transfer device and the traction device of the screen printer through a frame which is provided with a vertical punching mold, a horizontal punching mold and a control device; and small holes radially and uniformly distributed on the surface of a driving wheel of the traction device are communicated with an inner cavity which is externally connected with a draft device. The full-automatic screen printer can detect and automatically regulate the tension in the process of feeding and play a role of stretching to prevent materials from wrinkling in the process of travelling, automatically aligns edges and corrects deflection to improve the positioning accuracy, adheres dust on the surfaces of the materials by using the dedusting wheel, has better paper-advancing effect and on-line punching function, positions and punches conveniently and accurately, has high automation degree of the whole machine, and can effectively guarantee the printing quality of products.

Description

technical field [0001] The invention belongs to the field of printing machinery, in particular to a fully automatic screen printing machine. Background technique [0002] As an important printing equipment, screen printing machine is widely used in the printing field. The wrinkle and deflection of the material when feeding, and the dust attached to the surface of the material will affect the printing quality of the final product. Stability will also lead to unstable printing accuracy, resulting in waste of materials, and in severe cases, the product will be scrapped. Existing screen printing machines do not have the function of continuous online positioning and punching, and additional special punching equipment is required, and a special process is used to carry out punching operations. On the one hand, the number of machines and equipment is increased, and the working hours of the operation are increased. Also because of the connection problem of the two processes, the po...

[0002] As an important printing equipment, screen printing machine is widely used in the printing field. The wrinkle and deflection of the material when feeding, and the dust attached to the surface of the material will affect the printing quality of the final product. Stability will also lead to unstable printing accuracy, resulting in waste of materials, and in severe cases, the product will be scrapped

Existing screen printing machines do not have the function of continuous online positioning and punching, and additional special punching equipment is required, and a special process is used to carry out punching operations. On the one hand, the number of machines and equipment is increased, and the working hours of the operation are increased. Also due to the connection problem of the two processes, the positioning is unstable, which is easy to cause waste of materials
