At present, the common book wrapping methods mainly include newspaper calendar wrapping book cover, transparent book cover and transparent self-adhesive book cover. The first one is to wrap the old newspapers or calendars that are larger than the size of the book cover on the book. Although it is energy-saving and environmentally friendly, it makes the name of the book unrecognizable; the second is to directly put the book cover on the cover and back cover of the book, which is simple and convenient. But its material is relatively hard, and it is two layers of leather with the book, which is easy to slip and break; the third is to paste the transparent self-adhesive book cover on the writing, the material is soft and not easy to fall off, the disadvantage is that the book cover is easy to stick during the pasting process Together, it will cause the book cover to wrinkle and produce air bubbles. It is a purely manual operation, which is difficult, time-consuming and labor-intensive.

As shown in FIG. 1 , a book wrapping machine based on gear transmission mainly includes a housing 5 , a pair of meshing gears a and b, a paper delivery shaft 1 , a paper delivery shaft 9 , a roller shaft 7 and a separation shaft 6 . It is characterized in that: from the inner side of the housing 5 to the direction of the paper outlet, the paper release shaft 1, the paper receiving shaft 9 and the roller shaft 7 are sequentially installed, the separation shaft 6 is located above the roller shaft 7, and each shaft is vertically inserted into the two side panels of the housing 10, wherein the paper delivery shaft 1 and the paper delivery shaft 9 can rotate relative to the housing 5, the roller shaft 7 and the separation shaft 6 are fixed relative to the housing 5, and a pair of meshing gears a2 and gear b4 are connected with the paper delivery shaft 1 and the paper delivery shaft respectively. 9 constitutes a clearance and interference fit, and is located outside the side panel 10 of the housing 5 .

The book wrapping machine also includes an adaptive transmission ratio device installed on the paper release shaft 1, which is composed of a friction plate 18, a compression spring 19, and a compression nut 20, and the compression nut 20 is screwed on the end of the paper release shaft 1 part, the inner side compresses the compression spring 19, and the other end of the compression spring 19 is pressed on the paper release shaft 1 gear a2, and the other side of the gear a2 is in contact with the friction plate 18, and the friction plate 18 is fixed on the paper release shaft 1.

The book wrapping machine also includes a tension rod 3, which is located at the lower position in the middle of the paper delivery shaft 1 and the paper delivery shaft 9. The tension rod 3 vertically passes through the two side panels 10 of the housing 5 and is fixed.

The book wrapping machine also includes a pair of truncated cone-shaped positioning blocks 11 coaxially installed on the paper release shaft 1, the small ends of which are opposite, and the positioning blocks 11 can slide relative to the paper release shaft 1 under the action of a certain axial force, for Supports cover paper cores 17 of varying lengths.

A roller 8 is installed on the roller 7 , and the roller 8 can rotate relative to the roller 7 .

The gearless ends of the paper delivery shaft 1 and the paper delivery shaft 9 are easily separated from the side panel 10 to facilitate the replacement of the self-adhesive cover paper 14 .

The rear side of the housing 5 is a hand-held area, and the hand-held area is in the shape of an arc concentric with the paper-feeding shaft 1, and the bottom surface of the housing 5 and the upper cover 12 are respectively circumscribed to the arc.

The upper cover 12 of the housing 5 is made of transparent material, and is connected with the handle area of the housing 5 through a hinge.

Specific examples are as follows:

As shown in Figures 1, 2 and 3, the working principle of this book wrapping machine is that the book cover paper core 17 is clamped on the paper release shaft 1 by a pair of truncated cone-shaped positioning blocks 11, and can be positioned by sliding the truncated cone. Block 11, to accommodate different sizes of book covers. Under the action of the meshing gear a2 and gear b4, the self-adhesive cover paper 14 bypasses the tension rod 3 and reaches the separation shaft 6 and the roller 8. At this time, the self-adhesive cover paper 14 is separated into the book cover paper 16 and the Pad paper 15, the cover paper 16 after separating the pad paper is smoothly pasted on the surface of the book 13 under the rolling action of the roller 8; the pad paper 15 is wound around the separation shaft 6 to the paper delivery shaft 9, so as to achieve the purpose of recycling .

During use, first paste the book cover paper 16 behind the separation pad on the edge of the book 13, and exceed about 2 centimeters, then push forward with the hand-held book wrapping machine, and the book cover paper behind the separation pad paper torn off by the roller 8 16 is evenly pasted on the surface of the book 13, and when it reaches the spine, turn the book 13 over and continue to push the book wrapping machine forward until it completely wraps the book 13 and continues to push forward about 2 cm, cutting off the cover paper 16 after the separation pad paper , and then the book cover paper 16 after the separated pad paper of about 2 centimeters that both ends are excess is turned over and pasted on the inboard of book 13 back cover and cover, promptly completes a school bag book cover work. Since the line speed of the self-adhesive book cover paper 14 and the line speed of the pad paper 15 on the surface of the delivery shaft 9 are constantly changing, assuming that the speed of pushing the book wrapping machine is uniform, the self-adhesive book cover paper roll on the paper delivery shaft 1 becomes thinner as it is used. , the line speed will become smaller and smaller, and the pad paper roll on the delivery shaft 9 will become thicker and thicker, and the line speed will become larger and larger, which will cause the uncoordinated speed of putting paper and receiving paper. If only one or two books are wrapped, the impact may not be great, but if there are many books wrapped, the incongruity caused by the speed difference between loading and receiving paper will be obvious. Therefore, an adaptive transmission ratio device is specially designed, which is composed of friction plate 18, compression spring 19, and compression nut 20. The other end of 19 is compressed on the gear a2 of the paper release shaft 1, and the other side of the gear a2 is in contact with the friction plate 18, and the friction plate 18 is fixed on the paper release shaft 1. When the speed difference is not obvious, the friction between the gear a2 and the friction plate 18 can drive the paper delivery shaft 1 to rotate together, and when the speed difference accumulates to a certain extent, the force of the paper delivery shaft 9 pulling the backing paper 15 becomes larger When the friction force between the friction plates 18 of the gear a2 can be overcome, the gear a2 and the friction plates 18 will slip, and the paper-feeding shaft will slip relative to the gear a2 after 1 revolution, and no longer obey the transmission ratio between the gear a2 and the gear b4, thus Make sure that the book cover will not be pulled or even broken.

The gearless end of the paper release shaft 1 and the paper delivery shaft 9 is easy to separate from the side panel 10. After the self-adhesive book cover paper 14 is used up, it can be removed. Put down the paper shaft 1 and replace it with new paper, and remove the paper delivery shaft 9 to take off the backing paper 15 at the same time.

The above-mentioned specific embodiments are used to explain the utility model, rather than to limit the utility model. Within the spirit of the utility model and the protection scope of the claims, all technical solutions obtained by taking equivalent replacement or equivalent transformation to the utility model , all fall into the protection scope of the present utility model.
