Locating mechanism for film feeding roll of laser packaging film pressing machine

Abstract

The invention discloses a locating mechanism for a film feeding roll of a laser packaging film pressing machine. The top of a fixed base is screwed with a hex head screw, a locating pin is connected to the top of a connecting base in an inserted way, the fixed base and the connecting base are sleeved at two ends of the film feeding roll through grooves, slide bar are connected to opposite side walls of a fixed block in an inserted way, a stripe hole is formed in the slide bar, a locating rod is connected to the inner chamber of the stripe hole in an inserted way, an adjusting knob is connected to one end of the slide bar in an inserted way through the inner chamber of the fixed block, the upper end and the lower end of the film feeding roll are respectively welded with a bearing and a locating block, a locating hole is formed in the locating block, a support rod is connected to one end of an arc-shaped block, the support rod is fixed on the outer wall of a sliding block, a shaft lever is fixed at one end of the adjusting knob, and the outer wall of the shaft lever is screwed to the inner chamber of the sliding block by thread lines. The locating mechanism for a film feeding roll of a laser packaging film pressing machine is convenient to operate and accurate in positioning, and can provide better stationarity for a film during film pressing.

Description

technical field [0001] The invention relates to the technical field of film presses, in particular to a positioning mechanism for film feed rollers of laser packaging film presses. Background technique [0002] Laser holographic embossing anti-counterfeiting technology was introduced into my country in the late 1980s and early 1990s. At present, there are three major types of wide-format products: holographic paper (including laminated cardboard and transfer paper), holographic film and holographic anodized aluminum products. It has been closely integrated with the traditional packaging and printing industry technology. Laser packaging is a subdivision of the packaging industry and has achieved rapid development. Compared with other products in the packaging industry, laser packaging materials not only have novel and bright It is known as the most cutting-edge technical product in the world's packaging and printing industry. The application fields of laser materials have been...

AI Technical Summary

Problems solved by technology

The application fields of laser materials have been very extensive, and they have been rapidly promoted in industries such as food, medicine, daily chemical products, tobacco and wine, clothing, gift packaging, and decorative materials. The machine that prints the pattern on the laser film passing through the heating roller, the general film press machine is more troublesome when putting the laser film on the film feed roller, the operation is cumbersome, the accuracy is poor, and it is easy to be unbalanced due to the unbalanced effect of the film feed roller It leads to uneven stress on the film during the lamination process, especially when the two films are overlapped together for processing, the walking route is inconsistent, resulting in partial bonding after processing, which affects the quality of the finished product and greatly reduces the production efficiency. For this reason, we propose a positioning mechanism for the film feed roller of the laser packaging film press
