V-shaped operation platform mechanism

Abstract

The utility model discloses a V-shaped operation platform mechanism which is composed of a left supporting plate, a right supporting plate, a left supporting plate supporting rod, a right supporting plate supporting rod, a left supporting plate mounting plate, a right supporting plate mounting plate, a left supporting plate rebounding spring, a right supporting plate rebounding spring, a movable platform plate mechanism, a bottom supporting plate and a spine supporting piece. When the conditions that the left part is thin and the right part is thick (note: thin represents few pages and thick represents more pages) and the right part is thin and the left part is thick are generated in the page turning process of a book file, the self-adaptive fit between the pages and the glass surface of the downwards pressed glass pressing plate can be adjusted through the lifting of the left supporting plate and the right supporting plate with the springback mechanism and the springback supporting piece capable of springback; and therefore, a relatively good flattening effect of the page is achieved.

Description

Technical Field

[0001] The utility model is applied to a book and periodical scanner with a V-shaped pressing glass and a V-shaped operating platform for various bound documents without disassembly and binding. The application of the utility model aims to achieve a better effect of flattening the paper of the book and periodical scanner. Background Art

[0002] Ordinary V-shaped book scanners with V-shaped glass pressure frames are only equipped with a simple V-shaped operating platform mechanism without lifting adjustment. During the page turning process, the left page may be thinner and the right page may be thicker (note: "thin" represents fewer pages, and "thick" represents more pages) or the right page may be thinner and the left page may be thicker. When the V-shaped glass pressure frame is pressed down, the platform mechanism without lifting adjustment cannot ensure that the left and right pages always fit together with the surface of the V-shaped pressure frame glass. Summary of the Invention

[0003] The invention also provides a method for adjusting the position of the pages and the glass surface of the glass pressing plate by adjusting the position of the pages and the glass surface of the glass pressing plate to ensure that the pages are always in contact with each other during the page turning and scanning process of the V-shaped book scanner with a V-shaped glass pressing frame. During operation, first adjust the platform to align the center seam of the bound document 6 with the V-tip of the glass of the V-shaped glass pressing frame 4. When the V-shaped glass pressing frame 4 presses against the pages of the bound document 6, when the number of pages on the left side of the bound document 6 is relatively small, the support plate lifting and adjusting spring 10 will pull the support plate support rod 3 to make the support plate 1 rise and support the left part of the bound document. At the same time, the thicker right side of the bound document will be pressed down. At this time, the support plate lifting and adjusting spring 10 is in a pulled state. In this case, the support plate 1 can simultaneously press the pages of the bound document to the glass surface with balanced force under the adjustment of the support plate lifting and adjusting spring 10. In addition, the reboundable spine support 5 plays a cooperative role in pressing the spine of the bound document upward at the same time, so that the left and right pages of the bound document can always be kept in contact with the glass surface of the V-shaped pressing frame. By the same token, the effect of adaptive adjustment of left thick and right thin can also be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Combined with the drawings of the specification, the utility model is mainly composed of a pallet 1, a pallet support rod 3, a copy glass 9, a pallet lifting adjustment spring 10, a support rod mounting plate 2, a spine support 5, an opening and closing plate 11, a platform moving plate 8, a platform bottom plate 7 and a slide rail 12. Each pallet 1 of the left and right pallets is connected to one end of the four pallet support rods 3, and the pallet support rod 3 is connected to one end of the pallet lifting adjustment spring 10 (the number of springs used is configured according to the requirements of the rebound force of the pallet 1, but at least 2 are required for each pallet). The pallet lifting adjustment spring 10 The other end and the other end of the pallet support rod 3 are connected to the support rod mounting plate 2, the pallet 1 and the support rod mounting plate 2 are always in a parallel state, the support rod mounting plate 2 is installed on the opening and closing plate 11 at a certain angle, the opening and closing plate 11 is installed on the slide rail, the left and right opening and closing plates can adjust the gap between the left and right pallets according to the thickness of the volume of documents, the slide rails for installing the left and right opening and closing plates 11 are installed on the mobile platform plate 8, the mobile platform plate 8 can be moved left and right under manual or electric control, the mobile platform plate 8 is installed on the slide rail, and the slide rail is installed on the platform bottom plate 7;

[0011] During specific operation, first adjust the distance between the left and right support plates according to the thickness of the bound document, and then adjust the platform moving plate 8 so that the center seam position of the bound document 6 is aligned with the V-tip of the copy glass 9. When the glass pressing frame 4 presses the bound document down, the support plate on the side holding more papers will be pressed down by the copy glass 9, but the paper is pressed toward the copy glass 9 by the adjustment action of the support plate lifting and adjusting spring 10, and the support plate on the side holding less papers will rise under the action of the support plate lifting and adjusting spring 10 to press the paper toward the copy glass 9. In this case, the support plate 1 can simultaneously press the pages of the bound document to the glass surface with balanced force under the adjustment of the support plate lifting and adjusting spring 10, and the cooperative effect of the resilient spine support 5 pressing the spine of the bound document upward at the same time can achieve the effect of always keeping the left and right pages of the bound document in contact with the surface of the V-shaped pressing frame glass.
