Paper feeder

Abstract

The invention discloses a paper feeder. The paper feeder comprises a frame and a paper feeding head and is characterized by comprising a height adjustment device for adjusting the height of the paperfeeding head and a longitudinal adjustment device for adjusting the longitudinal position of the paper feeding head. Driving sources of the height adjustment device and the longitudinal adjustment device are both connected with an electrical connector. The paper feeder has advantages that electric driving is adopted in height and longitudinal adjustment of the paper feeding head, lifting of a feeding table board and side board width adjustment, and the driving sources are connected with the electrical connector to realize automatic operation.

Description

technical field The invention relates to an improved invention of a paper feeder, in particular to a paper feeder used in combination with a screen printing machine. Background technique Most of the sheet-fed automatic screen printing machines use a paper feeder to realize automatic paper feeding. There are several problems in the traditional sheet-fed paper feeder. 1. The circulating power of the paper feeder is transmitted through the main machine to drive the paper feeder to separate the paper. and delivery, when the paper specifications change, it is necessary to manually adjust the front, rear, up and down of the paper feed head, and adjust the left and right positions of the side stoppers to adapt to the changes in the paper, while manual adjustment has the problem of low efficiency; 2. In traditional sheet-fed paper feeders, in order to adjust the paper head up and down, back and forth, the air source is generally introduced from the outside with hoses. These pipeline...

Most of the sheet-fed automatic screen printing machines use a paper feeder to realize automatic paper feeding. There are several problems in the traditional sheet-fed paper feeder. 1. The circulating power of the paper feeder is transmitted through the main machine to drive the paper feeder to separate the paper. and delivery, when the paper specifications change, it is necessary to manually adjust the front, rear, up and down of the paper feed head, and adjust the left and right positions of the side stoppers to adapt to the changes in the paper, while manual adjustment has the problem of low efficiency; 2. In traditional sheet-fed paper feeders, in order to adjust the paper head up and down, back and forth, the air source is generally introduced from the outside with hoses. These pipelines need to be of sufficient length, and the redundant pipelines are often towering above the equipment, which increases the The height of the equipment increases the cost of equipment packaging and transportation, and it is exposed to the outside, posing safety hazards and hindering the visual inspection of the equipment; The switches are scattered and placed externally, which not only poses safety hazards, but also increases the horizontal size of the equipment, which is not conducive to packaging and transportation
