Description

Certificate extraction and separation device and certificate processing equipment Technical Field The invention relates to a certificate extraction and separation device and certificate processing equipment, and belongs to the technical field of office automation. Background At present, printing of a certificate with a thick cover sheet is always a difficult problem in the printing industry, and the general practice is to print required printing contents on paper and then bind the printing contents with the cover sheet. However, for registration certificates such as the real property certificates, the certificates cannot be printed first and then bound into a whole, and the certificates are often required to be manually turned over and printed one by one, so that the efficiency is very low, and the self-service printing of the certificates by the user cannot be realized. There are also some schemes on the market for solving the problem of page turning and printing of the certificate, wherein the first category comprises rubber roll paper rubbing, the general structure comprises an extraction roll and a pair of separation rubber roll groups, so that the extraction, separation and page turning of the certificate are realized, for example, a page turning and recycling mechanism suitable for issuing the certificate is disclosed by the publication number CN215204178U, the second category comprises extracting and page turning in a negative pressure mode, and the third category comprises directly grabbing the certificate by a mechanical arm, conveying and page turning. In the first scheme, a certain stability is provided, and the basic constraint on the certificate paper can be basically achieved, but the environment and the state of the certificate itself are relatively critical (the situation that the certificate cannot be curled) are relatively influenced, in the scheme, the two actions of extraction and separation are mutually influenced, the separation reliability needs to be improved, so that a plurality of certificates need to be prevented from entering between the separation roller sets, the meshing point of the separation roller sets is needed to be extruded, namely, the larger the resistance of the separation roller below the separation roller sets is more beneficial (the meshing pressure is increased, the damping of the separation roller below the separation roller sets is increased), the larger the resistance can cause difficulty in extracting the certificate (namely, the certificate is difficult to enter the meshing point of the separation roller sets), and if the certificate needs to easily enter the meshing point (the reliability of extraction is improved), the resistance of the separation roller below the separation roller sets is small (the separation pressure and the damping of the glue roller are reduced), and the reliability of the separation is seriously reduced, namely, the certificates are easy to enter between the separation roller sets. The second type of negative pressure mode has certain advantages, but the disadvantages are obvious, firstly, the static electricity is strong in dry weather in winter, one page is adsorbed by negative pressure, the next page is adsorbed to one block by static electricity and is difficult to separate, the negative pressure adsorption paper is dry in winter, the paper is curled, and the failure rate of negative pressure adsorption paper is not low. Secondly, the small negative pressure device is simple to acquire, but the sucking reliability is poor, and the large negative pressure device is expensive and complex. The third category is very costly and impractical for large-scale batch use. Disclosure of Invention The invention aims to overcome the defects of the prior art and provide a certificate extraction and separation device which can improve the accuracy of certificate extraction and separation and ensure that only one certificate is separated and enters a subsequent certificate treatment process. In order to solve the technical problems, the technical scheme of the invention is that the certificate extracting and separating device is arranged on a rack and comprises: A conveying separation roller pair, wherein the conveying separation roller pair comprises a conveying roller set suitable for being driven to rotate and a separation roller set suitable for being driven to rotate, the separation roller set is arranged below the conveying roller set, and a certificate passing channel for passing a certificate is formed between the separation roller set and the conveying roller set; a set of take-up rollers adapted to be driven in rotation to convey a specimen into the specimen passing path; the interval acquisition component is used for acquiring the interval of the certificate passing channel when the certificate passes through the certificate; The interval adjusting assembly is used for rotationally connecting the separation roller set and driving the s
