Description

Technical Field

[0001] The utility model relates to a glue overflow prevention mechanism for printing glue brushing, belonging to the technical field of glue overflow prevention. Background Art

[0002] Offset printing is also called offset printing in Guangdong and Hong Kong. It is a type of lithography and the main printing method. Offset printing can restore the color, contrast and level of the original with high precision and clarity. It is currently the most common paper printing method. It is suitable for posters, brochures, manuals, newspapers, packaging, books, magazines, calendars and other related color printed materials.

[0003] After searching, a Chinese patent with publication number CN214052366U discloses a material guide device for preventing glue overflow in the printing and processing of self-adhesive roll materials. Its technical points are: it includes a fixed plate, a first support rod is fixedly installed on the left side of the upper end of the plate body of the fixed plate, the end of the first support rod is fixedly connected to the first rotating shaft, and the first material guide roller is rotatably connected to the shaft body of the first rotating shaft, a second support rod is fixedly installed on the left side of the lower end of the plate body of the fixed plate, the end of the second support rod is fixedly connected to the second rotating shaft, and the second material guide roller is rotatably connected to the shaft body of the second rotating shaft, and the positions of the first support rod end and the second support rod end of the fixed plate are provided with angle adjustment devices. The first material guide roller and the second material guide roller are used to replace the traditional material baffle plate, and in the case of positioning the material guide, the edge of the material is rolled against the first material guide roller and the second material guide roller, and the friction between the edge of the material and the device is minimized during operation to achieve the purpose of preventing glue overflow.

[0004] The above scheme solves the problem that the edge of the self-adhesive strip rubs against the baffle, causing a small amount of adhesive to overflow onto the baffle and gradually accumulate. After accumulating to a certain level, the friction between the strip and the baffle increases sharply, and the amount of overflowed glue increases sharply, thereby affecting normal production and causing production interruption. However, since two angle adjustment devices are provided, the extreme angles need to be adjusted one by one when adjusting the rollers, which makes the adjustment more troublesome and has a low adjustment accuracy.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
