Description

Device for aligning seamless molding press Technical Field The utility model relates to the technical field of laser holographic molding, in particular to a device for aligning a seamless molding press. Background In the field of laser holographic anti-counterfeiting packaging, a seamless mould pressing technology is a core technology for realizing high-precision laser patterns (such as vertical lines, light columns and miniature characters). The product needs to strictly align the 1 st edition basic grating with the 2 nd edition enhancement pattern (the dislocation tolerance is less than or equal to 0.1 mm), otherwise, the defects of light beam fracture, text blurring and the like can be caused. The traditional molding press is dependent on manual experience in alignment, and has the following problems: 1. The adjustment mechanism is original, repeated trial and error is needed when the plate is pasted, a worker adjusts the position of the plate by visual inspection, the plate pasting can reach the production requirement only by 3-5 times on average, and the plate is consumed by single trial and error, so that waste is caused. 2. The precision and the efficiency are contradictory, namely the manual alignment limit precision is only +/-1 mm, and the high-end anti-counterfeiting product (such as a currency safety line) requires +/-0.1 mm. In order to improve the precision, workers need to stop the machine to manually knock the shaft sleeve micro-moving plate roller, and the operation is easy to damage equipment and time-consuming to adjust. Aiming at the defects of the prior art, the utility model discloses a device for aligning a seamless molding press so as to solve the problems. Disclosure of utility model Aiming at the technical problems in the prior art, the utility model provides a mechanical alignment device for a seamless molding press, which has the advantages of simple structure, low cost and reliable precision, solves the alignment problem, reduces the trial-and-error times and improves the production efficiency. The technical scheme for solving the technical problems is that the seamless molding press aligning device comprises a molding press body, a plate roller and a shaft sleeve; Support pieces are symmetrically arranged on two sides of the molding press body; the two ends of the plate roller are fixedly connected with the shaft sleeve; The middle part of each shaft sleeve is provided with a containing cavity which divides the shaft sleeve into an inner sleeve body close to the plate roller and an outer sleeve body far away from the plate roller; The supporting piece is embedded in the accommodating cavity at the corresponding end; The inner sleeve body and the outer sleeve body are respectively provided with a plurality of through holes of circumferential annular cloth, and all the through holes penetrate through the sleeve wall body to the accommodating cavity; The through hole is internally provided with a displacement member, and the inner end of the displacement member extends into the accommodating cavity and is abutted against the surface of the support member; The displacement member is provided with a locking member which is used for fixing the relative position between the displacement member and the support member after the displacement member is abutted against the support member; the inner side surface spacing of the outer sleeve bodies of the two sleeve bodies is larger than the outer side surface spacing of the two supporting pieces, and the radial depth of the accommodating cavity is larger than the radial thickness of the supporting pieces.
