A paper feeder for multiple bill collation and coding equipment

Abstract

The invention discloses a paper transport for a multi-joint invoice gathering coding device. The paper transport consists of a first supporting shaft (2.3.1), a second supporting shaft (2.3.2), a first belt pulley (2.3.3), a second belt pulley (2.3.4), a third belt pulley (2.3.5), a fourth belt pulley (2.3.6), a first belt (2.3.7), a second belt (2.3.8) and third driving wheel (2.3.9). The first belt (2.3.7) and the second belt (2.3.8) are provided with protruding nails. The provided paper transport has the following beneficial effects: pre-punched holes are sleeved on the protruding nails of the paper transport, so that all invoices are aligned accurately; with rotation of the belts, the invoices are sleeved at the protruding nails and can be transported timely, so that a phenomenon that the coding quality is influenced due to too small tension of the paper can be prevented; and the power is also provided for supplying and transmission of the invoices by the paper transport.

Description

technical field [0001] The invention relates to a paper feeder in the bill printing industry, and is especially suitable for page-collating and coding equipment for multi-part bills with pre-punched holes on both sides. Background technique [0002] The bills that are commonly used at present all adopt multiple sheets in one form, and each sheet of each sheet has the same serial number, and the back of each sheet has a copying function. When coding multi-part bills (the code is the invoice number), it is necessary to align the upper and lower positions of each bill in order to ensure that the printed multi-part bills are neat and consistent. Otherwise, if the top and bottom of the bill are misaligned, it will cause the upper and lower coding of the printed multi-part bill to be misplaced, and the coding position will be shifted, etc., which will affect the use. Another factor that needs to be strictly controlled during the coding process is the tension of the bill. If the t...

[0004] However, the existing coding equipment is not equipped with a paper feeder, which cannot guarantee that the bills are completely aligned up and down during the conveying process of the bills, nor can it guarantee that the tension of the bills during the conveying process is appropriate.

If the bills sent to the rolling device are not aligned up and down, and there is a positional offset between them, the offset will exist consistently after rolling, and it is not adjustable, which seriously affects the coding quality; if it is sent to The tension of the bills of the coding device is not well controlled, which will also affect the quality of coding
